[0022] [3. Door frame] The door frame 3 in the pachinko machine 1 will be described in detail mainly with reference to Figs. 5 to 10. Fig. 5 is a front view of the door frame in the pachinko machine. Fig. 6 is a left side view of the door frame, and Fig. 7 is a right side view of the door frame. Fig. 8 is a perspective view of the door frame seen from the front right, and Fig. 9 is a perspective view of the door frame seen from the front left. Fig. 10 is a cross-sectional view of the door frame cut in the vertical center and viewed from above.

[0023] The door frame 3 is formed in a rectangular shape extending vertically in a front view with approximately the same size as the inside of the outer frame 2, and is attached to the inside of the outer frame 2 so as to be able to open and close from the front side via the main frame 4. The door frame 3 is provided with a game window 201 that closes the game area 5a of the game board 5 into which the game ball B is dropped so as to be visible from the front side, an upper tray 130 that stores the game ball B to be dropped into the game area 5a, and a handle 111 that is operated by the player to drop the game ball B in the upper tray 130 into the game area 5a. The door frame 3 also decorates the entire front surface of the pachinko machine 1 and is provided with various decorative parts. Some of these various decorative parts are not decorated at all, while others are decorated on the entire front and back surfaces. This decorative plating is a precious metal plating such as chrome plating or hard gold plating, and has electrical conductivity, so that electromagnetic noise may enter.

[0024] Therefore, in this embodiment, among the various decorative parts, those that have decorative plating on the entire front and back are electrically connected to a metal door frame reinforcement unit in the door frame base unit of the door frame 3 described later via wiring (not shown) (some of the various decorative parts are electrically connected to the metal door frame reinforcement unit via wiring (not shown), while others are electrically connected by having a conductive member directly attached to the metal door frame reinforcement unit). This makes it possible to transmit electromagnetic noise that has entered the various decorative parts to the metal door frame reinforcement unit, thereby preventing the various decorative boards provided on the various decorative parts from entering the board ground.

[0025] Incidentally, electromagnetic noise that penetrates into those decorative parts that have decorative plating on the entire front and back surfaces is transmitted to the metal door frame reinforcement unit via wiring (not shown), then transmitted to the frame ground board 559 via the door frame metal ground wire described below, and then transmitted from the frame ground board 559 to the ground of the island equipment of the gaming hall via the island equipment ground wire, and is removed from the pachinko machine 1. In other words, in this embodiment, the metal door frame reinforcement unit serves as the frame ground on the door frame side.

[0026] The door frame 3 comprises a door frame base unit (not shown) which has a rectangular, frame-shaped outer shape extending vertically when viewed from the front, a lower door frame unit 100 which is provided on the front surface of the door frame base unit at a height of approximately 1 / 4 of the total height from the bottom end, an upper door frame unit 200 which is provided above the lower door frame unit 100 and on the front surface of the door frame base unit, and an upper door frame hinge portion and a lower door frame hinge portion (not shown) which are rotatably and detachably supported on the upper main frame hinge portion 510 and the lower main frame hinge portion 520 of the main frame 4.

[0027] The door frame base unit comprises a door frame base (not shown) whose outer shape when viewed from the front is formed into a square (rectangle) that extends vertically and has a play window 201 that penetrates from front to back, a door frame main relay board (not shown) attached to the lower rear side of the door frame base near the right end when viewed from the rear, a door frame sub-relay board (not shown) attached to the left side of the door frame main relay board when viewed from the rear, a handle rear relay board (not shown) attached to the left side of the door frame sub-relay board when viewed from the rear, a door frame relay board cover (not shown) that covers the door frame main relay board and part of the door frame sub-relay board from the rear, a handle rear relay board cover (not shown) that covers the handle rear relay board from the rear, and a cable cover (not shown) that covers the wiring cable (not shown).

[0028] The door frame base unit also includes a metal frame-shaped door frame reinforcement unit (not shown) attached to the rear side of the door frame base, a metal upper door frame hinge assembly 120 and a lower door frame hinge member 125 attached to the door frame reinforcement unit, and a metal cylinder lock 127 for opening and closing attached to the door frame reinforcement unit.

[0029] The door frame reinforcement unit is attached to the rear side of the door frame base to reinforce the door frame base and provide rigidity. The upper door frame hinge assembly 120 and the lower door frame hinge member 125 are for attaching the door frame 3 to the main frame 4 so that it can be opened and closed. The cylinder lock 127 cooperates with the locking unit 650 of the main frame 4 to be used for opening and closing the door frame 3 and the main frame 4, and for locking and opening the outer frame 2 and the main frame 4.

[0030] The door frame reinforcement unit functions as a door frame metal ground in addition to reinforcing the door frame base to provide rigidity, and is electrically connected to a frame ground board 559 via a door frame metal ground wire (not shown). The frame ground board 559 is electrically connected to the ground of the island equipment of the game hall via an island equipment ground wire (not shown).

[0031] The door frame lower unit 100 of the door frame 3 is equipped with a handle 111 that can be operated by a player to shoot a game ball B into the game area 5a, a bulging portion 120 that bulges forward, an upper tray 130 that is provided on the upper surface of the bulging portion 120 and stores the game ball B to be shot into the game area 5a, a lower tray 140 that is provided below the upper tray 130 and stores the game ball B, a door frame performance device 150 that is provided on the upper surface of the bulging portion and presents a predetermined performance to the player, an upper tray ball removal button 124 that is provided on the upper surface of the bulging portion 120 and releases the game ball B in the upper tray 130 into the lower tray, a ball lending button 125 and a return button 126 that are provided on the upper surface of the bulging portion 120, a door frame sub-display unit 185 that is provided behind the ball lending button 125 and the return button 126, and a lower front speaker 191 that is provided on the front surface of the bulging portion 120.

[0032] The upper door frame unit 200 of the door frame 3 comprises a game window 201 with an inverted U-shaped inner periphery which allows the game area 5a of the game board 5 to be viewed from the front, a transparent closing glass 205 which closes the game window 201, an upper door frame interior decorative unit 210 which is arranged along the inner periphery of the game window 201, an upper door frame exterior decorative unit 220 which is arranged on the outside of the upper door frame interior decorative unit 210, an upper door frame exterior edge decorative unit 230 which covers the upper door frame interior decorative unit 210 and the upper door frame exterior decorative unit 220, and an upper speaker unit 240 which is arranged on the upper front surface of the upper door frame exterior edge decorative unit 230.

[0033] The door frame 3 also includes a ball feeding unit (not shown) for feeding the game balls B stored in the upper tray 130 one by one to the ball launching device 540 of the main frame 4. The ball feeding unit includes a ball feeding solenoid 105 (see FIG. 67) controlled by the launch control unit 372 of the payout control board 370.

[0034] [3-1. Door frame lower unit] Next, the door frame lower unit 100 of the door frame 3 will be described in detail mainly with reference to Figs. 5 to 13. Fig. 11 is a cross-sectional view of the door frame lower unit cut at the center in the left-right direction and viewed from the right. Fig. 12(a) is a perspective view showing a state in which the first movable part of the door frame performance device has been moved to the upper end, and Fig. 12(b) is a perspective view showing a state in which the performance operation part has been moved to the upper end from the state in (a). Fig. 13(a) is an enlarged front view of the vicinity of the lower front speaker unit, and Fig. 13(b) is an enlarged front view showing a state in which the lower front speaker grill, grill decoration frame, and lattice decoration part in (a) have been removed.

[0035] The door frame lower unit 100 of the door frame 3 is disposed below the game window 201 that closes the game area 5a of the game board 5 held by the main frame 4 so that it can be seen from the front. The door frame lower unit 100 is provided with a handle unit 110 that is provided in the lower right corner when viewed from the front and that can be operated by a player to shoot a game ball B into the game area 5a, and bulging portions 120 that bulge forward above and to the left of the handle unit 110 relative to the surface that closes the front of the main frame 4.

[0036] The door frame lower unit 100 also includes an upper tray 130 for storing game balls B, which is arranged on the upper surface of the bulging portion 120 to surround the device placement section 123, a lower tray 140 for storing game balls B, which is arranged below the upper tray 130 and to the left of the center in the left-right direction, a door frame performance device 150 which is arranged in the device placement section 123 on the upper surface of the bulging portion 120 and can present a predetermined performance to the player, a door frame sub-display section 185 which is arranged in the upper right corner when viewed from the front, and a lower front speaker unit 190 which is arranged on the front surface of the bulging portion 120.

[0037] [3-1a.Handle unit] The handle unit 110 of the door frame lower unit 100 includes a handle 111 that a player can grasp and rotate, a handle cover 112 provided in front of the handle 111, and a handle base 113 that rotatably supports the handle 111. The handle unit 110 is provided within the handle base 113 and includes a handle rotation detection sensor 114 (see FIG. 67) that detects the rotation angle of the handle 111, a handle touch sensor 115 that detects that the player is touching the handle 111, a handle return spring (not shown) that biases the handle 111 in a counterclockwise direction, and a single button 116 that can be pressed by the player.

[0038] The handle unit 110 is inclined so that the rotation axis of the handle 111 moves to the right as it moves forward. This makes it easy for the player to grip the handle 111 of the handle unit 110 and allows the player to rotate it without feeling uncomfortable. Also, the handle unit 110 is configured such that the handle base 113 is extendable in the direction in which the rotation axis of the handle 111 extends, and can be held in a desired extended or extended position. This allows the position of the handle 111 in the front-rear direction to be adjusted, allowing the player to operate the handle 111 in a position that is easy for the player to operate.

[0039] The handle 111 is supported by a handle base 113 so as to be rotatable only within a predetermined angular range. The handle 111 has a plurality of protrusions (four in this example) that are spaced apart in the circumferential direction and protrude from the outer circumferential surface. The handle cover 112 is translucent, and can be decorated with illumination in various colors by a plurality of full-color LEDs arranged at the rear.

[0040] The handle rotation detection sensor 114 of the handle unit 110 is a variable resistor whose internal resistance changes according to the rotation angle of the handle 111. The driving force of a launch solenoid 331 in a ball launching device 540 (described later) changes according to the internal resistance of the handle rotation detection sensor 114, which changes by the rotation operation of the handle 111, and the game ball B can be shot into the game area 5a with a strength according to the rotation angle of the handle 111.

[0041] The handle touch sensor of the handle unit 110 detects the electrostatic capacitance of the handle 111, etc. When a player touches the handle 111, etc., the electrostatic capacitance of the handle 111, etc. changes, and therefore, by detecting the electrostatic capacitance of the handle 111, etc. using the handle touch sensor, it is possible to detect whether or not the player is touching the handle 111. In this embodiment, when the handle touch sensor 115 detects the player's contact and the handle 111 is rotated, the detection of the handle rotation detection sensor 114 is accepted, and the drive of the launch solenoid 331 is controlled with a strength according to the rotation angle of the handle 111, so that the game ball B can be shot in.

[0042] In other words, even if a player tries to shoot the game ball B into the game area 5a by rotating the handle 111 in some way without touching it, the handle touch sensor 115 does not detect the touch of the player, so the launch solenoid 331 is not driven and the game ball B cannot be shot in. This makes it possible to prevent a player from playing a game by rotating the handle 111 in a way other than the normal way, and reduces the load (burden) on the game hall in which the pachinko machine 1 is installed.

[0043] When the player presses the single shot button 116 of the handle unit 110 while rotating the handle 111, the drive of the launch solenoid 331 is stopped by the launch control unit 372 of the payout control board 370. This makes it possible to temporarily stop the launch of the game ball B without returning the rotation of the handle 111. Then, by releasing the pressing of the single shot button 116, the game ball B can be shot into the game area 5a again with the same shooting strength as before the single shot button 116 was operated.

[0044] [3-1b.bulge] The bulging portion 120 of the door frame 3 has a front view of a T-shape with a short axis extending vertically, and has an isosceles trapezoidal shape in plan view, with the rear end side being the full width of the door frame 3 in the left-right direction and narrowing toward the front (see FIG. 10, etc.). The bulging portion 120 bulges forward a length slightly longer than half the full width in the left-right direction. The top surface of the bulging portion 120 is slightly inclined with respect to the horizontal plane so that it is positioned downward as it approaches the front.

[0045] The bulging portion 120 bulges forward in the left-right direction at the center, which divides the overall width of the door frame 3 into thirds, over the entire height from the bottom end to the top of the door frame 3, and the remaining portions (portions on both the left and right sides) bulge forward up to about 1 / 3 of the overall height from the bottom end to the top of the door frame 3. This results in a T-shape when viewed from the front. The bulging portion 120 has a speaker mounting opening 120a that opens in a square shape at the bottom center of the front surface. The lower front speaker unit 190 is attached to this speaker mounting opening 120a.

[0046] The bulging portion 120 is provided with sound release slits 120b and heat release slits 120c extending vertically on both left and right sides of a portion (where the speaker mounting opening 120a is open) that extends vertically in a T-shape when viewed from the front. The sound release slits 120b are for releasing sound from a lower front speaker 191 (described later) to the outside. The heat release slits 120c are for releasing heat from a first lifting / lowering drive motor 175b, a second lifting / lowering drive motor 182, the lower front speaker 191, and the like in the door frame performance device 150 (described later) to the outside.

[0047] The bulge portion 120 comprises a bulge upper decorative portion 121 provided on the upper edge of the front surface, a bulge lower decorative portion 122 provided on the lower edge of the front surface, a device placement portion 123 provided on the top surface at the center in the left-right direction so as to protrude forward from the rear end side, an upper tray ball removal button 124 provided on the top surface for releasing game ball B in the upper tray 130 into the lower tray 140, and a ball lending button 125 and a return button 126 provided behind the upper tray ball removal button 124.

[0048] The bulge-upper decorative part 121 and the bulge-lower decorative part 122 are translucent milky white and formed in a semi-cylindrical shape. The bulge-upper decorative part 121 extends along the upper edge of the front surface of the bulge 120, and is provided to decorate the upper edge of the front side of the upper plate 130 described above. The bulge-upper decorative part 121 has multiple LEDs 121a therein (see FIG. 16). The multiple LEDs 121a are aligned in a line in the direction in which the bulge-upper decorative part 121 extends. These multiple LEDs 121a are full-color LEDs.

[0049] The distance between the two rear ends of the bulge upper decorative part 121, which are spaced apart in the left-right direction, matches the distance between the lower ends of the upper interior decorative parts 212, which are spaced apart in the left-right direction, in the door frame upper interior decorative unit 210 of the door frame upper unit 200, which will be described later. This bulge upper decorative part 121 is formed to match the upper interior decorative part 212 when assembled to the door frame 3, and forms a single continuous decoration together with the upper interior decorative part 212. This bulge upper decorative part 121, together with the upper interior decorative part 212, constitutes a first luminous area LA1 that illuminates and decorates the area around the game window 201.

[0050] In addition, the bulge upper decorative portion 121 decorates the upper side above the upper end of the front peripheral wall 134 of the upper tray 130, and raises the front wall (front peripheral wall 134) of the upper tray 130. This bulge upper decorative portion 121 is configured so that a portion of the light from the LED 121a is irradiated into the upper tray 130 (inside the storage area 131), and the game balls B stored in the storage area 131 can be irradiated with light to create a luminous decoration.

[0051] The lower-bulge decorative part 122 extends along the lower edge of the front surface of the bulge 120. The lower-bulge decorative part 122 has multiple LEDs 122a inside (see FIG. 16). The multiple LEDs 122a are aligned in a line in the direction in which the lower-bulge decorative part 122 extends. The multiple LEDs 122a are full-color LEDs.

[0052] The device mounting section 123 has a planar shape that is a combination of a rectangle that is long in the left-right direction and an isosceles trapezoid with the front side of the rectangle as the base. The left-right width of the rear end side of the device mounting section 123 is approximately half the overall width of the door frame 3. The device mounting section 123 is open at the top on the upper surface of the bulging section 120 and is formed in a container shape that extends from the top into the inside of the bulging section 120.

[0053] The upper tray ball removal button 124 is provided in the right corner of the upper surface of the bulge portion 120, to the right of the upper tray 130. By pressing the upper tray ball removal button 124 downward, the game ball B stored in the upper tray 130 can be released from the discharge port 136 to the lower tray 140. This upper tray ball removal button 124 releases the game ball B in the upper tray 130 to the lower tray 140 only while it is pressed, and when the pressure is released, it moves upward to return to its original state and stops releasing to the lower tray 140.

[0054] The upper tray ball removal button 124 has a square outer shape. The upper tray ball removal button 124 has an illuminating decorative part 124a that is illuminated by an LED disposed below. The illuminating decorative part 124a is disposed so as to surround the outer periphery of the upper tray ball removal button 124. By illuminating the illuminating decorative part 124a, the upper tray ball removal button 124 can be illuminated and decorated.

[0055] The ball lending button 125 is disposed behind the upper tray ball removal button 124 on the upper surface of the bulging portion 120. The ball lending button 125 has a circular outer shape. The return button 126 is disposed to the right of the ball lending button 125 on the upper surface of the bulging portion 120. The return button 126 has an equilateral triangular outer shape.

[0056] The ball lending button 125, when pressed after inserting cash or a prepaid card into a ball lending machine (not shown) provided adjacent to the pachinko machine 1, supplies a predetermined number of game balls B into the upper tray 130, lending the game balls B to the player. The return button 126, when pressed, returns the cash or prepaid card inserted into the ball lending machine minus the amount of the lent game balls B. The remaining amount of cash or prepaid card inserted into the ball lending machine is displayed on the door frame sub-display unit 185.

[0057] [3-1c.Top plate] The upper tray 130 of the door frame 3 is recessed downward on the upper surface of the bulging portion 120, and has a storage area 131 in which the game balls B are stored. The storage area 131 is composed of a front area 131a (area surrounded by a dashed line in FIG. 15) on the front side of the device placement section 123, and side areas 131b (areas surrounded by a dashed line in FIG. 15) on both the left and right outer sides of the device placement section 123, which are connected to each other by the front area 131a.

[0058] The front region 131a has a substantially constant width in the front-rear direction and extends in the left-right direction. The left side region 131b extends in the front-rear direction so that its width in the left-right direction narrows from the rear end side toward the front region 131a side. The right side region 131b extends in the front-rear direction so that its width in the left-right direction widens toward the rear halfway from the front end side of the front region 131a side, and then extends in the front-rear direction so that its width narrows toward the rear end side. The upper tray 130 (storage region 131) is formed to surround the front side and both left and right outer sides of the device placement section 123.

[0059] The upper tray 130 comprises a bottom wall 132 forming the bottom surface, a rear peripheral wall 133 rising upward from the rear end of the bottom wall 132, a front peripheral wall 134 rising upward from the front end of the bottom wall 132, a supply port 135 opening forward at the rear end of the left side region 131b, a discharge outlet 136 opening forward at the rear end of the right side region 131b, and an alignment section 137 provided near the discharge outlet 136 for aligning the game balls B toward the discharge outlet 136.

[0060] The bottom wall 132 of the upper tray 130 is inclined so as to become lower from the supply port 135 side toward the delivery port 136. The front peripheral wall 134 and the rear peripheral wall 133 rise almost vertically. The surfaces of the bottom wall 132, the rear peripheral wall 133, and the front peripheral wall 134 are formed in a mirror-like shape. The bottom wall 132, the rear peripheral wall 133, and the front peripheral wall 134 of the upper tray 130 form a storage area 131. The depth of the upper tray 130 (the height from the bottom wall 132 to the upper ends of the rear peripheral wall 133 and the front peripheral wall 134) is formed deeper than the diameter of the game ball B even at the shallowest part (near the supply port 135).

[0061] The supply port 135 is for supplying the game balls B dispensed from the dispensing device 580 of the main body frame 4 into the storage area 131. The delivery port 136 is for delivering the game balls B stored in the storage area 131 from the storage area 131 to the ball launching device 540 or the lower tray 140. The alignment section 137 is bent downward so that the bottom wall 132 becomes lower toward the delivery port 136 near the boundary between the rectangle and the isosceles trapezoid in the device arrangement section 123, which combines a rectangle and an isosceles trapezoid in a plan view.

[0062] The upper tray 130 also includes a storage light-emitting decoration section 138 having multiple LEDs 138a capable of emitting light toward the storage area 131. The multiple LEDs 138a of the storage light-emitting decoration section 138 are provided on the rear peripheral wall 133, and are provided at a height that is above half the outer diameter of the game ball B from the bottom wall 132 and approximately parallel to the upper end of the rear peripheral wall 133. These LEDs 138a are full-color LEDs. By illuminating the LEDs 138a of the storage light-emitting decoration section 138, the storage area 131 and the game balls B stored in the storage area 131 can be illuminated and decorated.

[0063] The upper tray 130 has a bulge upper decorative part 121 of the bulge 120 provided at the upper end of the front peripheral wall 134, and the bulge upper decorative part 121 raises the front end side of the storage area 131, allowing more game balls B to be stored. In addition, the upper tray 130 is configured so that a portion of the light from the LED 121a of the bulge upper decorative part 121 is irradiated into the storage area 131, and the game balls B in the storage area 131 are also illuminated and decorated by the light from the bulge upper decorative part 121.

[0064] The upper tray 130 has a front area 131a in front of the device placement section 123 where the door frame effect device 150 is placed, and side areas 131b on both the left and right sides, and the front area 131a allows the game balls B to be stored in front of the door frame effect device 150, making it easier for the player to see the game balls B stored in the upper tray 130. In addition, in the upper tray 130, the two side areas 131b connected by the front area 131a are areas that extend forward and backward, making it easier for the player to see the game balls B stored in the side areas 131b in addition to the front area 131a.

[0065] Therefore, by making the game balls B in the upper tray 130 easier to see, the player can be made aware of the amount of stored game balls B. Even if the game balls B in the upper tray 130 are consumed as the game progresses and the amount of stored game balls B decreases, the player can be made to easily recognize the decrease in the amount of stored game balls B and can have game balls B replenished in the upper tray 130. This prevents game balls B from disappearing from the upper tray 130 without the player realizing, prevents sudden interruptions to play, prevents the player from becoming discouraged due to an interruption in play, and suppresses a decrease in the player's interest in the game.

[0066] Furthermore, since the upper tray 130 makes it easy for the player to see the game ball B in the front area 131a and the two side areas 131b, the player can instantly recognize whether or not there is game ball B in the front area 131a by simply dropping his or her gaze from the game area 5a to the door frame performance device 150 below. This eliminates the need for the player to carefully check whether or not there is game ball B in the upper tray 130, making it easier for the player to concentrate on the game, making the game more enjoyable and preventing a decline in interest.

[0067] Furthermore, in the upper tray 130, the game ball B supplied from the supply port 135 into the storage area 131 passes through the front area 131a and is released out of the storage area 131 from the release port 136. Therefore, when the game ball B in the upper tray 130 is consumed by playing a game, the game ball B flows in front of the player (front area 131a), making it easier for the player to recognize the consumption speed and amount of the game ball B, making it easier to achieve the above-mentioned action and effect.

[0068] In addition, the upper tray 130 is provided with a storage light-emitting decorative section 138 that emits light into the storage area 131. The light from the storage light-emitting decorative section 138 (LED 138a) is reflected upward by the game balls B, and the light from the storage light-emitting decorative section 138 makes the game balls B stored in the upper tray 130 sparkle and illuminate, decorating them. This allows the player to enjoy the illuminating decoration of the game balls B, and also strongly draws the player's attention to the game balls B stored in the upper tray 130, allowing the player to check the amount of game balls B stored in the upper tray 130 and achieving the same effect as described above.

[0069] In addition, since the inner surfaces of the bottom wall 132, rear peripheral wall 133, and front peripheral wall 134 of the upper tray 130 are formed in a mirror-like shape, the game balls B stored in the upper tray 130 are reflected onto the peripheral walls of the upper tray 130, giving the player the illusion that game balls B are stored on the other side of the peripheral walls, making it appear as if a large number of game balls B are stored in the upper tray 130.

[0070] Furthermore, in the upper tray 130, an alignment section 137 is provided near the outlet 136 to align the game balls B, so that clogging of the game balls B near the outlet 136 can be prevented, and the game balls B stored in the upper tray 130 can be smoothly sent from the outlet 136 to the ball launcher 540 or the lower tray 140. Therefore, interruption of the game due to clogging of the game balls B can be avoided, allowing the player to enjoy the game and suppressing a decline in interest.

[0071] In addition, in the upper tray 130, the outlet 136 located in the right side area 131b can be seen from the front, so that it is possible to see the game ball B being released from the outlet 136, which was not possible to see in previous pachinko machines, and this can surprise the player and strongly attract the player's attention, thereby achieving the same effect as described above.

[0072] [3-1d. Bottom plate] The lower tray 140 is located below the upper tray 130, to the left of the central part of the bulging portion 120 that bulges forward, and is formed in the shape of a shallow tray that opens upward. A gap is provided between the lower tray 140 and the upper tray 130 (the underside of the left side part of the bulging portion 120) to allow the player to insert his / her hand. The front surface of the lower tray 140 is formed in approximately the same shape as the front surface of the bulging portion 120 in a plan view.

[0073] The lower tray 140 is formed at the lowest part of the bottom wall and has an openable and closable lower tray ball removal hole 141 (see Figure 9), a lower tray ball removal button 142 for opening and closing the lower tray ball removal hole 141 to eject game ball B in the lower tray 140 downward, and a full tank detection sensor 143 (see Figure 67) for detecting when the lower tray 140 is full of game balls B.

[0074] The lower tray 140 is supplied with game balls B in the upper tray 130 by operating the upper tray ball removal button 124. In addition, when the upper tray 130 is full of game balls B, the lower tray 140 is supplied with game balls B paid out from the payout device 580. When the lower tray 140 is full of game balls B, the full tank detection sensor 143 detects that the lower tray 140 is full, and when the full tank of the lower tray 140 is detected, the payout of game balls B by the payout device 580 is temporarily stopped. Thereafter, when the full tank in the lower tray 140 is resolved (the full tank detection sensor 143 is no longer detecting), the temporary suspension of payout is lifted.

[0075] The lower tray ball removal button 142 is provided on the front of the lower tray 140, and has a rectangular outer shape. When the lower tray ball removal button 142 is pressed backwards, the lower tray ball removal hole 141 opens and the lower tray ball removal button 142 remains pressed. When the lower tray ball removal button 142 is pressed backwards further in this state, the lower tray ball removal hole 141 closes and the lower tray ball removal button 142 moves forward, returning to its original state.

[0076] The lower tray ball removal button 142 has a light-emitting decoration part 142a that emits light by an LED (not shown). The light-emitting decoration part 142a is arranged so as to surround both the left and right sides and the upper side of the lower tray ball removal button 142. By illuminating the light-emitting decoration part 142a, the lower tray ball removal button 142 can be illuminated and decorated. For example, during a "jackpot" game in which many game balls B are paid out, the light-emitting decoration part 142a can illuminate and decorate the lower tray ball removal button 142, so that the player's attention can be directed to the lower tray 140, and the game balls B in the lower tray 140 can be discharged into a dollar box or the like below by operating the lower tray ball removal button 142, and it is possible to avoid the lower tray 140 becoming full and the payout of the game balls B being temporarily suspended.

[0077] [3-1e. Overall configuration of the door frame production device] The door frame effect device 150 is disposed in the device placement section 123 provided on the upper surface of the bulging section 120.

[0078] [3-1e-1. Equipment cover] The device cover 151 is formed in a shape in plan view that is a combination of a rectangular shape long in the left-right direction, which is the same as the device arrangement section 123, and an isosceles trapezoid with the front side of the rectangular shape as the base. The device cover 151 has an opening 151a that opens widely in the shape of an isosceles trapezoid at the part of the isosceles trapezoid, an inclined surface part 151b that is bent and inclined so that the rear end side is upward near the center in the front-rear direction at the part of the rectangular shape, and a plurality of grill holes 151c that penetrate in a hexagonal shape near the front end of the part of the rectangular shape. The device cover 151 is inclined as a whole so that the front end side is lower. A first movable part 155 is inserted into the opening 151a of the device cover 151.

[0079] The upper end of the inclined surface portion 151b of the device cover 151 coincides with the lower end of the door frame upper cover 232 of the door frame upper unit 200. In addition, the device cover 151 is inclined so that the front side of the inclined surface portion 151b is lower toward the front. This allows the game ball B to roll forward and be released into the upper tray 130 even if it is placed on the upper surface of the device cover 151.

[0080] [3-1e-2. Door frame display device] The door frame performance display device 152 has a display screen for displaying a performance image formed in a rectangular shape elongated from left to right, and the left-right length is slightly shorter than 1 / 2 the overall width of the door frame 3.

The door frame performance display device 152 is a liquid crystal display device with a screen ratio of 16:9.

[0081] [3-1e-3. Lower speaker unit] The lower speaker unit 153 has a pair of lower speakers 153a spaced apart from each other on the left and right, a lower speaker base 153b to which the pair of lower speakers 153a are attached, and a lower speaker decorative part 153c attached to the lower speaker base 153b and decorating the outer periphery of the lower speakers 153a and the space between the lower speakers 153a. The pair of lower speakers 153a are tweeters that output high-pitched sounds.

[0082] The lower speaker base 153b has a front surface that is inclined so that the rear edge is located above the front edge, and a rear surface that extends downward perpendicularly from the rear edge of the front surface to the front surface, and is formed in a long container shape that is open downward. The lower speaker base 153b also has circular mounting holes formed on the front surface that are spaced apart on the left and right. The front surface of the lower speaker base 153b is inclined at an angle smaller than the angle of inclination from the horizontal of the door frame performance display device 152 (see FIG. 11, etc.).

[0083] The lower speaker decorative part 153c is attached to the front of the lower speaker base 153b, and is composed of an annular part arranged on the outer periphery of the lower speaker 153a, and multiple arc-shaped parts arranged between the pair of lower speakers 153a. The lower speaker decorative part 153c is translucent, and can be decorated with light by illuminating an LED mounted on a lower speaker decorative board (not shown).

[0084] The lower speaker unit 153 is attached inside the lower speaker base 153b so that the pair of lower speakers 153a face forward from the mounting holes of the lower speaker base 153b. This allows the pair of lower speakers 153a to be directed toward the vicinity of the head of a player seated in front of the pachinko machine 1. The upper end of the lower speaker unit 153 is located at a height slightly lower than the vertical center of the door frame performance display device 152, and the lower end is located at a height slightly lower than the lower end of the door frame performance display device 152.

[0085] The lower speaker unit 153 has a front end located forward from the rear end of the opening 151a of the device cover 151 (slightly rearward from the performance operation unit 160), and a rear end located near the front end of the inclined surface portion 151b of the device cover 151. The lower speaker unit 153 can be seen through the transparent device cover 151. The sound output from the pair of lower speakers 153a can be radiated well to the outside (outside the pachinko machine 1) through the grill hole 151c of the device cover 151 and the grill hole 156b of the first movable part main body 156.

[0086] In addition, the lower speaker unit 153 can illuminate and decorate the lower speaker decorative part 153c using the LEDs on the lower speaker decorative board (not shown), thereby illuminating and decorating the area between the lower speaker 153a and the speaker grill of the lower speaker 153a (the device cover 151 and the upper wall of the first movable part main body 156), allowing players to see the illuminated decoration inside the speaker, which has not been seen in previous pachinko machines.

[0087] [3-1e-4. First movable part] The first movable part 155 includes a transparent first movable part body 156 in the shape of a container with the rear and bottom open, a first movable part base 157 attached to the underside of the first movable part body 156, a first movable part cover 158 attached to the top surface of the first movable part body 156, and a first movable part decorative board 159 attached to the inside of the side surface of the first movable part body 156 (see Figs. 11 and 12). The first movable part 155 is disposed in an opening 151a of the device cover 151. The first movable part 155 is supported by a first lifting mechanism 170 so as to be able to rise and fall, and is raised and lowered by the first lifting mechanism 170.

[0088] The shape of the first movable part body 156 in a plan view is similar to the shape of the opening 151a of the device cover 151, and is formed in a shape that combines a rectangle that is long in the left-right direction with an isosceles trapezoid with the front side of the rectangle as the base. The first movable part body 156 is formed in a container shape that is open at the rear and bottom, with an upper wall that combines a rectangle with an isosceles trapezoid, and side walls that extend downward from the sides of the upper wall excluding the rear side. The upper wall (upper surface) of the first movable part body 156 is inclined so that the front side is lower, and curved so that the center in the left-right direction is higher.

[0089] The first movable part body 156 has an opening 156a that penetrates the upper wall in the form of a rectangular shape elongated from side to side near the front end, a number of grill holes 156b that penetrate the upper wall in a hexagonal shape in the area other than the opening 156a, and a number of through holes 156c that are arranged in a row in the circumferential direction in the side wall and penetrate the side wall in a rectangular shape. The opening 156a is inserted into the lower end of the opening frame part 158a of the first movable part cover 158. The through hole 156c is formed in a size that allows the LED 159a mounted on the first movable part decorative board 159 to face outward.

[0090] The first movable part base 157 is formed in a flat plate shape that is long in the left-right direction. The first movable part base 157 is formed so that the width in the front-rear direction is shorter than the width in the front-rear direction at the opening 156a of the first movable part body 156. The first movable part base 157 is attached to the first movable part body 156 so that the front end is at approximately the same position in the front-rear direction as the front end of the opening 156a of the first movable part body 156. The first movable part base 157 is attached to the first movable part body 156 in a horizontal state. A pair of lift sliders 172 of the first lift mechanism 170 is attached to the lower surface of the first movable part base 157, and a second lift base 181 of the second lift mechanism 180 is attached to the upper surface.

[0091] The first movable part cover 158 has an outer shape and is formed to be the same size as the upper wall of the first movable part body 156. The first movable part cover 158 has a horizontally elongated rectangular opening frame part 158a corresponding to the opening 156a of the first movable part body 156, and a plurality of louver parts 158b extending left and right and spaced apart in the front-rear direction. The first movable part cover 158 has a plating layer with a silver metallic luster on the surface. The opening frame part 158a of the first movable part cover 158 protrudes downward at its lower end further than the lower end of the louver part 158b, and is inserted into the opening 156a of the first movable part body 156. The performance operation part 160 is inserted into the frame of the opening frame part 158a.

[0092] The louver portion 158b of the first movable part cover 158 extends with a constant width except for both ends in the left and right direction, and is formed in a triangular shape with both ends in the left and right direction expanding obliquely forward. The multiple (here, five) louver portions 158b are provided in the front-rear direction at intervals slightly larger than the outer diameter of the game ball B. This allows the game ball B to be stored between the louver portions 158b. Incidentally, one game ball B can be stored between the first louver portions 158b from the front, two game balls B can be stored between the second louver portions 158b, and three game balls B can be stored between the third louver portions 158b (see FIG. 15).

[0093] The first movable part decorative board 159 has a plurality of LEDs 159a mounted on the front surface. The plurality of LEDs 159a are arranged at positions corresponding to the through holes 156c of the first movable part main body 156. The first movable part decorative board 159 is attached to the inside of the side wall of the first movable part main body 156, so that the mounted plurality of LEDs 159a face the outside through the through holes 156c of the side wall. The LEDs 159a of the first movable part decorative board 159 are full-color LEDs.

[0094] When the LED 159a of this first movable part decorative board 159 is illuminated with the first movable part 155 lowered (normal state), it can illuminate and decorate the upper part of the rear peripheral wall 133 of the upper tray 130 through the gap between the rear peripheral wall 133 of the upper tray 130 and the side wall of the first movable part main body 156. Also, when the LED 159a of the first movable part decorative board 159 is illuminated with the first movable part 155 raised, it can illuminate and decorate the side wall of the first movable part main body 156, and can irradiate light into the storage area 131 and forward (towards the player).

[0095] [3-1e-5. Production operation section] The performance operation unit 160 is provided so as to be movable up and down with respect to the first movable unit 155, and is a so-called push button that can be operated by a player by pressing it. The performance operation unit 160 is supported so as to be movable up and down by a second lifting mechanism 180, and is raised and lowered by the second lifting mechanism 180 (see Figs. 11 and 12).

[0096] The performance operation unit 160 comprises a translucent pressing operation unit 161 having the word "PUSH" formed on its upper surface, an operation unit decorative board 162 arranged below the pressing operation unit 161 and having a number of LEDs mounted on its upper surface, an operation unit movable base 163 on whose upper surface the pressing operation unit 161 and the operation unit decorative board 162 are attached, an operation unit base 164 which supports the operation unit movable base 163 so that it can be raised and lowered and whose lower surface is attached to the first movable unit 155 via a second lifting mechanism 180 (second lifting base 181), an operation unit spring which urges the operation unit movable base 163 upward, and a press detection sensor 165 (see Figure 67) which detects the pressing operation unit 161 moving downward against the urging force of the operation unit spring.

[0097] The pressing operation part 161 is a rectangular shape that is long from side to side, and the word "PUSH" is formed in relief on the upper surface. The pressing operation part 161 is formed so that its outer periphery is slightly smaller than the inside of the frame of the opening frame part 158a of the first movable part cover 158.

[0098] The multiple LEDs mounted on the upper surface of the operation unit decoration board 162 are full-color LEDs. A first LED that emits light upward and a second LED that emits light outward along the upper surface of the operation unit decoration board 162 are mounted on the upper surface of the operation unit decoration board 162. The operation unit decoration board 162 can illuminate and decorate the pressing operation unit 161 (the letters "PUSH") by illuminating the first LED. In addition, by illuminating the second LED, the peripheral wall of the operation unit movable base 163 can be illuminated and decorated, and when the performance operation unit 160 is at the lowered end, the opening frame portion 158a of the first movable part cover 158 can be illuminated and decorated.

[0099] The operation unit movable base 163 is formed in a box shape that is long from side to side and open at the bottom. The operation unit movable base 163 is formed to be slightly smaller than the outer circumference of the pressing operation unit 161. The pressing operation unit 161 is attached to the upper surface of the operation unit movable base 163 so as to sandwich the operation unit decorative board 162. The operation unit base 164 is inserted into the operation unit movable base 163 from below.

[0100] The operation unit base 164 is composed of a box-shaped portion that is long from side to side and is open at the top and large enough to be inserted into the inside of the operation unit movable base 163, and a flange-shaped portion that protrudes outward from the box-shaped portion to the same position as the outer periphery of the operation unit movable base 163. The operation unit base 164 supports the operation unit movable base 163 so that it can be raised and lowered within a predetermined range. A second lifting mechanism 180 is attached to the underside of this operation unit base 164.

[0101] The upper end of the operation spring abuts against the lower surface of the upper wall of operation unit movable base 163, and the lower end abuts against the upper surface of the lower wall of operation unit base 164. Pressing detection sensor 165 is attached inside operation unit base 164, and detects a detection piece (not shown) of operation unit movable base 163 to detect a pressing operation of pressing operation unit 161 via operation unit movable base 163.

[0102] [3-1e-6. First lifting mechanism] 11, the first lifting mechanism 170 is attached inside the bulging portion 120 and serves to lift and lower the first movable portion 155. The first lifting mechanism 170 includes a pair of lifting rails 171 attached to the inside of the bulging portion 120 at a distance from each other on the left and right and extending vertically, a pair of lifting sliders 172 each guided in the vertical direction by the pair of lifting rails 171, a connecting portion 173 connecting the pair of lifting sliders 172 to each other, a pair of rod-shaped lifting arms 174 each having one end rotatably attached to the lifting slider 172 and the other end rotatably attached to the bulging portion 120, a first lifting drive mechanism 175 which rotates each of the pair of lifting arms 174, and a first lifting detection sensor 176 which detects the lifting position of the lifting slider 172 (first movable portion 155).

[0103] The pair of lift rails 171 are spaced apart laterally by an interval longer than the left-right length of the performance operation unit 160 (press operation unit 161). The pair of lift rails 171 are attached inside the bulging portion 120 so as to extend vertically. The pair of lift sliders 172 have their upper ends attached to the underside of the first movable part base 157 of the first movable part 155, and their lower ends attached to the connecting part 173.

[0104] The front ends of the pair of lifting arms 174 are attached to the corresponding lifting sliders 172 so as to be rotatable about an axis extending in the left-right direction and so as to be slidable in the longitudinal direction of the lifting arms 174. The rear ends of the pair of lifting arms 174 are attached to the bulging portion 120 so as to be rotatable about an axis extending in the left-right direction. Each of the pair of lifting arms 174 has a slit 174a extending in the longitudinal direction at a position closer to the front end than the center in the longitudinal direction.

[0105] The first lifting / lowering drive mechanisms 175 are provided for each of the pair of lifting / lowering arms 174. That is, a pair of first lifting / lowering drive mechanisms 175 are provided. The first lifting / lowering mechanism 170 can lift and lower the first movable unit 155 (performance operation unit 160) via the pair of lifting / lowering sliders 172 to which the tips of the pair of lifting / lowering arms 174 are respectively attached, by rotating each of the pair of lifting / lowering arms 174 by the first lifting / lowering drive mechanism 175 in a direction in which the front ends of the pair of lifting / lowering arms 174 move upward.

[0106] The first lifting drive mechanism 175 is slidably inserted into the slit 174a of the lifting arm 174 and has a first lifting pin 175a that revolves around an axis extending in the left-right direction, and a first lifting drive motor 175b that revolves the first lifting pin 175a. More specifically, the first lifting drive mechanism 175 has a flat drive base 175c that is attached inside the bulging portion 120 and extends in the front-rear and up-down directions, a spur gear-shaped lifting gear 175d that is rotatably attached to the drive base 175c around an axis extending in the left-right direction and has the first lifting pin 175a attached at a position eccentric to the rotation axis, and a drive gear 175e that meshes with the lifting gear 175d and is attached to the rotation axis of the first lifting drive motor 175b.

[0107] In this embodiment, two first lift drive motors 175b are attached to the drive base 175c, and drive gears 175e attached to the rotation shafts of the first lift drive motors 175b are meshed with the lift gears 175d, respectively. In other words, one lift gear 175d is rotated by the two first lift drive motors 175b.

[0108] When the drive gears 175e attached to the respective rotation shafts of the two first lift drive motors 175b of the first lift drive mechanism 175 are rotated in the same direction, the lift gears 175d meshing with the drive gears 175e rotate, and the first lift pins 175a revolve around the axis of the lift gears 175d. As the first lift pins 175a revolve, the first lift pins 175a slide within the slits 174a of the lift arm 174 and press the inside of the slits 174a in the vertical direction, causing the lift arm 174 to rotate (pivot) around its rear end. As a result, the front end of the lift arm 174 moves in the vertical direction, so that the first movable part 155 can be raised and lowered via the lift slider 172 to which the front end of the lift arm 174 is attached.

[0109] The first lifting / lowering detection sensor 176 is in a detection state when the pair of lifting / lowering sliders 172 are positioned at the downward movement end (lowering end). In other words, the first lifting / lowering detection sensor 176 detects, via the lifting / lowering sliders 172, that the first movable part 155 is positioned at the lowering end.

[0110] [3-1e-7. Second lifting mechanism] The second lifting mechanism 180 is attached to the upper surface of the first movable part base 157 of the first movable part 155, and comprises a second lifting base 181 that supports the operation unit base 164 of the performance operation unit 160 so that it can be raised and lowered, a second lifting drive motor 182 attached to the second lifting base 181, a second lifting pin 183 that is attached to the rotating shaft of the second lifting drive motor 182 and revolves at an eccentric position relative to the rotating shaft, a lifting transmission piece 184 that has a slit 184a extending in the front-to-rear direction into which the second lifting pin 183 is slidably inserted and has an upper part that is attached to the operation unit base 164, and a second lifting detection sensor 180a that detects the rise and fall of the second lifting base 181 (performance operation unit 160).

[0111] The second lifting base 181 of the second lifting mechanism 180 supports the operation unit base 164 so that it can be raised and lowered in a direction perpendicular to the upper surface of the pressing operation unit 161 (the direction of an inclined axis that moves forward as it extends upward).

[0112] In the second lifting mechanism 180, when the second lifting pin 183 is revolved by the second lifting drive motor 182, the second lifting pin 183 slides within the slit 184a of the lifting transmission piece 184 and presses the inner surface of the slit 184a in the vertical direction, causing the lifting transmission piece 184 to move in the vertical direction. Since the operation unit base 164 of the performance operation unit 160 is attached to this lifting transmission piece 184, the performance operation unit 160 can be raised and lowered via the lifting transmission piece 184.

[0113] In the second lifting mechanism 180, when the lifting transmission piece 184 (performance operation unit 160) is positioned at the lower end, the second lifting pin 183 is positioned near the rear end of the slit 184a extending in the front-rear direction. In other words, the second lifting pin 183 is positioned at the bottom dead center. When the lifting transmission piece 184 is to be raised from this state, the second lifting drive motor 182 revolves the second lifting pin 183 so as to have a forward movement vector. As a result, the second lifting pin 183 slides forward within the slit 184a, and the second lifting pin 183 presses upward against the inner surface of the slit 184a, causing the lifting transmission piece 184 to move upward.

[0114] As the second lift pin 183 further revolves, when the line connecting the center of the second lift pin 183 and the center of revolution passes the central axis of the slit 184a, the second lift pin 183 slides backward inside the slit 184a while pressing the inner surface of the slit 184a upward. Then, when the second lift pin 183 reaches the vicinity of the rear end of the slit 184a, the drive of the second lift drive motor 182 stops, and the revolution of the second lift pin 183 stops. In this state, the second lift pin 183 is located at the top dead center, and the lift transmission piece 184 is located at the upper end.

[0115] When the lift transmission piece 184 (performance operation unit 160) is positioned at the upper end and a force is applied to move the lift transmission piece 184 downward by, for example, pressing the performance operation unit 160, the second lift pin 183 is positioned at the top dead center, so no force in the front-to-rear direction is applied to the second lift pin 183. Therefore, the second lift pin 183 does not revolve, so the lift transmission piece 184 does not move downward.

[0116] Furthermore, when the performance operation unit 160 is pressed while the lift transmission piece 184 is positioned at the lift end, the player positioned in front of the performance operation unit 160 operates it, so that a rearward movement vector acts on the performance operation unit 160 in addition to a downward movement vector. In contrast, in the lift end state, the second lift pin 183 is positioned at the rear end of the slit 184a, so even if a rearward movement vector acts on the second lift pin 183 through the slit 184a, the second lift pin 183 abuts against the rear end of the slit 184a, preventing the second lift pin 183 from revolving, and the lift transmission piece 184 does not move downward, so that the performance operation unit 160 can be maintained at the lift end position.

[0117] The second lifting / lowering detection sensor 180a is in a detection state when the second lifting / lowering base 181 is located at the downward movement end (lowering end). In other words, the second lifting / lowering detection sensor 180a detects, via the second lifting / lowering base 181, that the performance operation unit 160 is located at the lowering end.

[0118] [3-1f. Door frame sub-display section] The door frame sub-display unit 185 is disposed to the right of the door frame performance display device 152 in the door frame performance device 150, behind the upper tray ball removal button 124, the ball lending button 125, and the return button 126. The door frame sub-display unit 185 is composed of three 7-segment LEDs lined up on the left and right. The door frame sub-display unit 185 is disposed in an inclined state so that the lower end side is positioned forward relative to the upper end side. The lower end of the door frame sub-display unit 185 is disposed at the same height as the upper surface of the bulge portion 120 from which the upper tray ball removal button 124, the ball lending button 125, and the return button 126 protrude.

[0119] The door frame sub-display unit 185 comprises a frame-shaped sub-display unit decorative frame 186 that illuminates and decorates the outer periphery of three square 7-segment LEDs, and a transparent sub-display unit cover 187 that covers the three 7-segment LEDs and the sub-display unit decorative frame 186 and is inclined at the same angle as the inclined surface portion 151b of the device cover 151 in the door frame performance device 150.

[0120] [3-1g. Lower front speaker unit] As shown in Figures 11 and 13, the lower front speaker unit 190 comprises a lower front speaker 191 attached to the rear of the speaker mounting opening 120a of the bulge portion 120, a lower front speaker grill 192 having a plurality of grill holes passing therethrough and closing the speaker mounting opening 120a, a horizontal lattice-shaped grill decoration frame 193 disposed in front of the lower front speaker grill 192 and attached to the front of the bulge portion 120, rod-shaped lattice decoration portions 194 respectively disposed on the rear side of each lattice portion in the grill decoration frame 193, and lattice decoration LEDs 195 provided at both ends of each lattice decoration portion 194 to illuminate and decorate the lattice decoration portion 194.

[0121] The lower front speaker 191 is a woofer that outputs low-frequency sounds. The lower front speaker grill 192 is attached to the inside of the bulging portion 120. The lower front speaker grill 192 is made of punching metal.

[0122] The grill decoration frame 193 has a plated layer with a silver metallic luster on the surface. The grill decoration frame 193 is composed of a rectangular frame along the inner circumference of the speaker mounting opening 120a of the bulging portion 120, and a plurality of lattice sections arranged vertically spaced apart by connecting two sides extending vertically of the frame. The lattice sections extending to the left and right of the grill decoration frame 193 extend at a constant width in the portion (general portion) excluding both ends in the left and right direction, and are formed into a trapezoid shape in which both ends in the left and right direction expand obliquely downward toward the ends and then extend at a constant width.

[0123] The lattice decoration part 194 is translucent and formed in a cylindrical shape that is long in the left-right direction. Both ends of the lattice decoration part 194 in the left-right direction are located behind the trapezoidal part of the lattice part of the grill decoration frame 193, and the remaining part is located below the general part of the lattice part. This allows the lattice decoration part 194 to be viewed from the front, except for both ends. The multiple lattice decoration parts 194 are provided in front of the lower front speaker grill 192. The lattice decoration LED 195 is a full-color LED.

[0124] The lower front speaker unit 190 can output low-pitched (low-frequency) sounds from the lower front speaker 191. This lower front speaker unit 190 faces forward from the front of the bulging portion 120 that bulges forward, so it can apply sound pressure to the player seated in front of the pachinko machine 1. In addition, the lower front speaker unit 190 can illuminate and decorate the lattice decoration portion 194 by appropriately illuminating the multiple lattice decoration LEDs 195, and can illuminate and decorate the inside of the grill decoration frame 193 (the front side of the lower front speaker grill 192) through the lattice decoration portion 194.

[0125] [3-1h. Cylinder lock] Next, a brief description will be given of the cylinder lock 127 of the door frame base unit. The cylinder lock 127 is attached to a cylinder mounting frame of a metal door frame reinforcement unit (not shown) and is used to open and close the door frame 3 and the main frame 4, and to open and close the outer frame 2 and the main frame 4 in cooperation with the locking unit 650. The cylinder lock 127 includes a metal cylindrical cylinder body (not shown) that extends forward and backward, a metal keyhole 128 formed on the front end surface of the cylinder body, and a metal rotation transmission member (not shown) that is attached to the rear side of the cylinder body, is inserted into the keyhole 128, and rotates together with the rotation of a regular metal key.

[0126] The cylinder body of the cylinder lock 127 penetrates the front piece of the cylinder mounting frame of the door frame reinforcement unit from the rear, and the rear end is attached to the front piece. The rotation transmission member is formed in a cylindrical shape (more specifically, a conical cylinder shape whose diameter increases toward the rear) with an open rear, and has a pair of notches cut from the rear end toward the front at positions opposite each other across the central axis. The rotation transmission member is formed so that when the door frame 3 is closed relative to the main frame 4, a metal transmission cylinder 654 of a metal locking unit 650 in the main frame 4 is inserted from the rear, and the pair of protrusions of the transmission cylinder 654 are inserted into the pair of notches, so that the rotation of the rotation transmission member (the key inserted in the keyhole 128) can be transmitted to the transmission cylinder 654 to rotate it. When the door frame 3 is closed relative to the main frame 4 and the rotation transmission member of the cylinder lock 127 in the door frame 3 is in contact with the transmission cylinder 654 of the locking unit 650 in the main frame 4, the cylinder lock 127 and the locking unit 650 are electrically connected.

[0127] When opening the main frame 4 relative to the outer frame 2 and when opening the door frame 3 relative to the main frame 3, the cylinder lock 127 is rotated in a predetermined direction (either clockwise or counterclockwise) by an attendant such as a game parlor clerk, who inserts a genuine metal key into the keyhole 128 of the cylinder lock 127. When the attendant such as a game parlor clerk inserts a genuine metal key into the keyhole 128 of the cylinder lock 127, the attendant becomes charged with static electricity and discharges it, causing electromagnetic noise to be transmitted to the cylinder lock 127 via the genuine metal key. Therefore, in this embodiment, various boards (for example, boards having a power supply line or a board ground line) are not arranged in the vicinity of the cylinder lock 127 to prevent the intrusion of electromagnetic noise.

[0128] [3-2. Door frame upper unit] Next, the door frame upper unit 200 of the door frame 3 will be described in detail mainly with reference to Figs. 5 to 10 and Fig. 14. Fig. 14(a) is an enlarged front view of the upper part of the door frame, and Fig. 14(b) is an enlarged front view showing the state in which the grill decoration frame and the lattice decoration part are removed in Fig. 14(a). The door frame upper unit 200 of the door frame 3 includes a game window 201 that allows the inside of the game area 5a of the game board 5 held by the main frame 4 to be viewed from the front when the door frame 3 is closed to the main frame 4, a door frame upper unit base 202 that has an outer periphery that is long vertically and an inner periphery that becomes the game window 201 is formed in an inverted U shape that is opened downward, and a transparent closing glass 205 that is provided on the door frame upper unit base 202 and closes the inverted U-shaped inner periphery (game window 201) of the door frame upper unit base 202.

[0129] The upper door frame unit 200 also comprises an upper door frame interior decorative unit 210 arranged in a band shape along the inner periphery of the inverted U-shape of the game window 201 on the front surface of the upper door frame unit base 202, an upper door frame exterior decorative unit 220 arranged outside the upper door frame interior decorative unit 210 on the front surface of the upper door frame unit base 202, an upper door frame outer edge decorative unit 230 covering the upper door frame interior decorative unit 210 and the upper door frame exterior decorative unit 220, and an upper speaker unit 240 arranged on the upper front surface of the upper door frame unit base 202.

[0130] [3-2a. Door frame upper unit base] The door frame upper unit base 202 forms the rear surface of the door frame upper unit 200 (see FIG. 10). The door frame upper unit base 202 is flat and formed in a gate shape that is open downward. When viewed from the front, the door frame upper unit base 202 has an outer periphery that is long vertically and a rectangular shape, and an inner periphery that is open downward and is formed in an inverted U shape. The size of the inner periphery of the door frame upper unit base 202 is formed larger than the playing area 5a of the playing board 5 arranged behind it.

[0131] [3-2b.Closing glass] The closing glass 205 is detachably provided at the rear end of the door frame upper unit base 202 so as to close the inner periphery (game window 201) of the door frame upper unit base 202 (see FIG. 10). This closing glass 205 is for closing the front side of the game area 5a so as to prevent the game ball B from falling forward from within the game area 5a of the game board 5 held by the main body frame 4 when the door frame 3 is closed relative to the main body frame 4. The closing glass 205 is transparent reinforced glass.

[0132] [3-2c. Door frame upper interior decoration unit] The door frame upper interior decorative unit 210 comprises a wall-shaped upper interior base 211 which extends along the inner circumference of the door frame upper unit base 202 at a constant width and protrudes forward, a semi-cylindrical upper interior decorative part 212 which extends along the upper interior base 211 and is provided at the front end of the upper interior base 211, and an upper interior decorative substrate 213 which is provided behind the upper interior decorative part 212 and has multiple LEDs 213a mounted on its front surface.

[0133] The upper internal base 211 is formed in an inverted U-shape when viewed from the front. At the front end of the upper internal base 211, a pair of linearly extending portions of the inverted U-shape extend vertically in the up-down direction, and the semicircular arc-shaped portion of the inverted U-shape curves to protrude forward as it goes upward. This upper internal base 211 is formed to be opaque. The left-right distance at the lower end of the upper internal base 211 matches the distance between the rear ends of the bulging portion upper decorative portion 121 of the bulging portion 120 of the door frame lower unit 100, which are spaced apart on the left and right.

[0134] The upper interior decorative part 212 is translucent milky white and formed in a semi-cylindrical shape. The upper interior decorative substrate 213 is attached to the upper interior base 211, and a plurality of LEDs 213a mounted on the front surface are arranged in a row along the upper interior decorative part 212. The plurality of LEDs 213a of the upper interior decorative substrate 213 are full-color LEDs. By appropriately illuminating the plurality of LEDs 213a of the upper interior decorative substrate 213, the upper interior decorative part 212 can be illuminated and decorated.

[0135] The door frame upper interior decorative unit 210 is formed so that, when assembled to the door frame 3, the lower end of the upper interior decorative part 212 coincides with the rear end of the bulge upper decorative part 121 of the bulge 120, and the upper interior decorative part 212 and the bulge upper decorative part 121 form a single continuous decoration.

[0136] The upper interior decorative part 212 of this door frame upper interior decorative unit 210, together with the bulge upper decorative part 121, constitutes a first circumferential light area LA1 (area surrounded by a dashed line in FIG. 16) that illuminates and decorates the area around the game window 201. In addition, since the upper interior decorative part 212 is formed in a milky white color, it is possible to reduce the light from the multiple LEDs 213a and radiate it outward, thereby preventing the inside of the game window 201 surrounded by the upper interior decorative part 212 from becoming difficult to see due to glare, and the game area 5a can be clearly seen from the front through the game window 201.

[0137] [3-2d. Door frame upper exterior decorative unit] The door frame upper external decorative unit 220 has its rear end attached to the front surface of the door frame upper unit base 202, and comprises a plurality of protruding bases 221 which protrude forward and are arranged at intervals in the vertical direction, an upper external apex decorative portion 222 provided at the front end of the protruding base 221, upper external valley decorative portions 223 each arranged between the protruding bases 221, upper external apex LEDs 224 each arranged behind the upper external apex decorative portion 222, and upper external valley LEDs 225 arranged behind the upper external valley decorative portion 223.

[0138] The protruding base 221 is formed in an isosceles triangle shape in a side view. The protruding base 221 extends in the left-right direction from the outer peripheral surface of the upper internal base 211 to the vicinity of the left and right side pieces of the door frame upper unit base 202, and is formed so as to extend outward from the upper internal base 211. The front end of the protruding base 221 protrudes forward to a position substantially the same as the front end of the portion with which the upper internal base 211 is in contact.

[0139] The upper outer apex decorative parts 222 are formed in a cylindrical shape extending in the left-right direction, with both left and right ends formed in a hemispherical shape. The upper outer apex decorative parts 222 are formed so that the outer diameter of the cylinder is approximately 1 / 3 the outer diameter of the upper inner decorative part 212. The upper outer apex decorative parts 222 are each formed to a length corresponding to the left-right length of the protruding base 221 provided thereon. These upper outer apex decorative parts 222 are translucent.

[0140] The upper outer valley decorative part 223 is composed of a part (vertical surface part) extending parallel to the front surface of the door frame upper unit base 202 between the protruding bases 221, and a part (slope part) extending obliquely from the upper side or lower side of the part along the lower side or upper side of the protruding base 221 to the vicinity of the front end of the protruding base 221. The upper outer valley decorative part 223 has a mirror-like plating layer on its surface (front surface). In addition, the upper outer valley decorative part 223 has a square opening formed in the part extending parallel to the front surface of the door frame upper unit base 202 so that the upper outer valley LED 225 arranged at the rear faces forward.

[0141] The upper outer apex LED 224 is a full color LED. The upper outer valley LED 225 is a high brightness full color LED.

[0142] The door frame upper exterior decorative unit 220 can illuminate and decorate the upper exterior apex decorative portion 222 by appropriately illuminating the upper exterior apex LED 224. In addition, the door frame upper exterior decorative unit 220 can illuminate and decorate the upper exterior valley decorative portion 223 by appropriately illuminating the upper exterior valley LED 225, and can brightly illuminate the space between the upper exterior apex decorative portions 222 that are spaced apart in the vertical direction.

[0143] The upper outer apex decorative part 222 and the upper outer valley decorative part 223 of the door frame upper outer decorative unit 220 constitute a second circumferential area LA2 (area surrounded by a two-dot chain line in FIG. 16) that illuminates and decorates the outside of the first circumferential area LA1 around the game window 201. In addition, the front ends of the upper outer apex decorative part 222 and the upper outer valley decorative part 223 of the door frame upper outer decorative unit 220 are located rearward of the front end of the upper inner decorative part 212 of the door frame upper inner decorative unit 210, so that the light irradiated from the upper outer apex LED 224 and the upper outer valley LED 225 toward the game window 201 is blocked by the upper inner base 211 and the upper inner decorative part 212, and even if the upper outer apex decorative part 222 and the upper outer valley decorative part 223 are illuminated and decorated, it is prevented that the inside of the game window 201 becomes difficult to see due to glare, and the game area 5a can be viewed in good condition from the front through the game window 201.

[0144] [3-2e. Door frame upper outer edge decorative unit] The door frame upper outer edge decorative unit 230 comprises a plurality of upper outer edge LEDs 231 arranged in a row along the outer peripheral edge (both left and right sides and the top side) of the door frame upper unit base 202, a door frame upper cover 232 attached to the outer peripheral edge of the door frame upper unit base 202 and covering the door frame upper inner decorative unit 210 and the door frame upper outer decorative unit 220, and an opaque decorative portion 233 provided on both the left and right side walls of the door frame upper cover 232. The plurality of upper outer edge LEDs 231 are full color LEDs.

[0145] The door frame upper cover 232 is composed of a pair of side walls extending forward from positions near the left and right ends of the door frame upper unit base 202, an upper wall connecting the upper edges of the pair of side walls and extending forward from a position near the upper end of the door frame upper unit base 202, and a front wall connecting the front edges of the pair of side walls and the front edge of the upper wall, and is formed in a box shape that is open at the rear and bottom. The door frame upper cover 232 is formed to be transparent overall.

[0146] The door frame upper cover 232 is formed in a shape that conforms to the shape of the front end of the upper interior decorative part 212 so that the front end of the side wall is located slightly forward of the front end of the upper interior decorative part 212. In detail, the front end of the side wall of the door frame upper cover 232 extends vertically from the lower end to a height near the upper end of the part that extends linearly in an inverted U shape in the game window 201, and then extends in an arc shape so as to be positioned forward as it moves upward to approximately the same height as the state of the door frame upper unit base 202. In addition, the front ends of the left and right side walls of the door frame upper cover 232 are curved in such a way that the parts that are curved in an arc shape toward the top move closer to each other as they move upward.

[0147] The door frame upper cover 232 is formed with a pair of speaker mounting openings 232a at both left and right corners of the upper part of the front wall, for mounting the grill decoration frame 243 of the upper speaker unit 240 and the like.

[0148] The opaque decorative portion 233 is provided on the outer surfaces of the left and right side walls of the door frame upper cover 232. The opaque decorative portion 233 has a slit 233a extending forward and backward at a position at the same height as the protruding base 221 of the door frame upper outer decorative unit 220. Through the slit 233a of the opaque decorative portion 233, a part of the transparent side wall of the door frame upper cover 232 faces outward.

[0149] The door frame upper outer edge decorative unit 230 covers the door frame upper interior decorative unit 210 and the door frame upper exterior decorative unit 220 so that they can be seen from the front with the door frame upper cover 232. In addition, the door frame upper outer edge decorative unit 230 can illuminate and decorate the outer edge of the door frame upper unit base 202 and the outer edge of the front wall of the door frame upper cover 232 (the front ends of the side walls and the top wall) by appropriately illuminating the multiple upper outer edge LEDs 231.

[0150] In addition, since the door frame upper outer edge decorative unit 230 has opaque decorative parts 233 on both the left and right outer sides, it is possible to prevent light from the upper outer apex LED 224 and upper outer valley LED 225 of the door frame upper outer decorative unit 220 from being irradiated onto other players seated in front of other pachinko machines placed adjacent to this pachinko machine 1.

[0151] The upper outer edge LEDs 231 (the outer edge of the front end of the upper door frame cover 232) of the upper door frame outer edge decorative unit 230 constitute a third circumferential light area LA3 (the area surrounded by a dashed line in FIG. 16) that illuminates and decorates the outside of the second circumferential light area LA2 around the game window 201. The upper outer edge LEDs 231 of the upper door frame outer edge decorative unit 230 are disposed on the front side of the upper door frame unit base 202, that is, behind the front end of the upper inner decorative part 212 of the upper door frame inner decorative unit 210. Therefore, the light irradiated from the upper outer edge LEDs 231 to the game window 201 side is blocked by the upper inner base 211 and the upper inner decorative part 212. Even if the upper outer edge LEDs 231 are illuminated, it is prevented that the inside of the game window 201 becomes difficult to see due to glare, and the game area 5a can be viewed in good condition from the front through the game window 201.

[0152] [3-2f. Upper speaker unit] The upper speaker unit 240 comprises upper speakers 241 respectively mounted near both left and right corners at the upper front surface of the door frame upper unit base 202, upper speaker grills (not shown) which close the speaker mounting openings 232a of the door frame upper cover 232 in front of each upper speaker 241, a horizontal lattice-shaped grill decoration frame 243 disposed in front of the upper speaker grills and attached to the front wall of the door frame upper cover 232, rod-shaped lattice decoration portions 244 disposed behind the upper speaker grill at approximately the same intervals as each lattice portion in the grill decoration frame 243, and lattice decoration LEDs 245 provided at the outer left and right ends of each lattice decoration portion 244 for illuminating and decorating the lattice decoration portion (see Figure 14).

[0153] The upper speakers 241 are each installed at an angle facing slightly downward in the left-right center of the door frame upper unit 200. The upper speakers 241 are installed further back than the adjacent upper outer apex decorative part 222 of the door frame upper outer decorative unit 220. The upper speakers 241 are full-range speakers that output a full range of sound from low to high tones. The upper speaker grill is installed on the inside (rear surface of the front wall) of the door frame upper cover 232. The upper speaker grill is made of punched metal.

[0154] The grill decoration frame 243 has a plated layer with a silver metallic luster on the surface. The grill decoration frame 243 is composed of a frame portion shaped along the inner circumference of the speaker mounting opening 232a of the door frame upper cover 232, and a plurality of lattice portions arranged vertically spaced apart by connecting two sides extending vertically of the frame portion. The lattice portions extending to the left and right of the grill decoration frame 243 extend at a constant width in the portion (general portion) excluding the end portions on the left and right outer sides of the door frame 3, and are formed into a trapezoid shape in which the end portions on the left and right outer sides extend at a constant width after expanding obliquely downward toward the end portions.

[0155] The lattice decoration part 244 is translucent and formed in a cylindrical shape that is long in the left and right directions. The lattice decoration part 244 can be seen from the front through the upper speaker grill. The lattice decoration LED 245 is a full-color LED.

[0156] The upper speaker unit 240 is located close to the head of the player seated in front of the pachinko machine 1, and can output high-quality stereo sound to the player. In addition, the upper speaker unit 240 can illuminate and decorate the lattice decoration part 244 by appropriately illuminating the multiple lattice decoration LEDs 245, and can illuminate and decorate the inside of the grill decoration frame 243 (the rear side of the upper speaker grill) through the lattice decoration part 244.

[0157] In addition, in the front view of the upper speaker unit 240, the upper outer apex decoration part 222 arranged inside the upper speaker grill (grill decoration frame 243) is located forward of the upper speaker 241. In other words, the lattice decoration part 244 and the upper outer apex decoration part 222, which can be illuminated, are arranged between the upper speaker 241 and the upper speaker grill. As a result, when the upper outer apex decoration part 222 and the lattice decoration part 244 are illuminated, the player can see an effect in which the inside of the speaker grill is illuminated, which has not been seen in previous pachinko machines.

[0158] [3-3. Overall structure of the door frame] Next, the overall configuration of the door frame 3 will be described in detail with reference to Figs. 5 to 16. Fig. 15 is a plan view of the door frame lower unit showing a state in which game balls are stored in the upper tray of the door frame. Fig. 16 is an explanatory diagram showing the circumferential light area in the door frame. When the front of the main body frame 4 is closed, the door frame 3 allows most of the front of the game board 5 held by the main body frame 4, including the game area 5a, to be visible from the front through the game window 201. In addition, the front side of the game board 5 (game area 5a) can be closed by the closing glass 205 of the game window 201.

[0159] As shown in FIG. 16, the door frame 3 has a bulging upper decorative part 121 and an upper inner decorative part 212 connected in a ring shape, and the upper tray 130, the door frame performance device 150, and the game window 201 are arranged inside the ring. In other words, the upper tray 130, the door frame performance device 150, and the game window 201 are surrounded by the bulging upper decorative part 121 and the upper inner decorative part 212 (first circumferential light area LA1). Furthermore, the outside of the upper inner decorative part 212 is surrounded by the upper outer apex decorative part 222 and the upper outer valley decorative part 223 (second circumferential light area LA2), and the upper outer edge LED 231 (third circumferential light area LA3). In other words, the game window 201 is triple-surrounded by the three circumferential light areas, the first circumferential light area LA1, the second circumferential light area LA2, and the third circumferential light area LA3.

[0160] The door frame 3 is formed so that the storage area 131 of the upper tray 130 surrounds the front and both left and right sides of the door frame performance device 150, and the game ball B supplied from the supply port 135 flows along the front edge of the bulge portion 120 and is sent out from the delivery port 136 to the outside (the lower tray 140 or the ball launching device 540).

[0161] In the door frame 3, in a normal state, the first movable part 155 and the performance operation part 160 of the door frame performance device 150 are each located at the downward movement end (lowering end). In this state, the upper surface of the first movable part 155 (first movable part main body 156) is located slightly above the upper surface of the device cover 151 through the opening 151a of the device cover 151. Also, the pressing operation part 161 of the performance operation part 160 is located slightly above the upper surface of the first movable part main body 156 through the opening 156a of the first movable part main body 156.

[0162] The door frame 3 is provided with a bulging upper decorative part 121 over the entire length at the upper end of the front peripheral wall 134 of the upper tray 130. The bulging upper decorative part 121 raises the upper end of the wall that stores the game balls B in the upper tray 130. The upper end of the front side (front area 131a side) of the bulging upper decorative part 121 is higher than the front end of the upper surface of the door frame performance device 150 (first movable part 155) in the normal state. As a result, when the upper tray 130 is filled with game balls B, the game balls B overflow onto the door frame performance device 150 side, making it easier for the player to recognize that the upper tray 130 is full of game balls B, and preventing the game balls B from spilling forward from the upper tray 130.

[0163] The door frame 3 has the upper tray ball removal button 124, ball lending button 125, and return button 126 concentrated in the right corner on the upper surface of the bulging portion 120, to the right of the upper tray 130. The surface on which the upper tray ball removal button 124, ball lending button 125, and return button 126 are provided is located higher than the upper tray 130 and lower than the bulging portion upper decorative portion 121, and is inclined to become lower toward the front. As a result, when a game ball B is placed on the surface on which the upper tray ball removal button 124, ball lending button 125, and return button 126 are provided, the game ball B can be rolled toward the upper tray 130 by the surface and the bulging portion upper decorative portion 121, and released into the upper tray 130.

[0164] In addition, since the surfaces of the bottom wall 132, rear peripheral wall 133, and front peripheral wall 134 that constitute the upper tray 130 (i.e., the inner surfaces of the upper tray 130) of the door frame 3 are formed in a mirror-like manner, the game balls B stored in the upper tray 130 are reflected on the inner surface of the upper tray 130, and the reflected game balls B are visible, creating the illusion that a large number of game balls B are stored in the upper tray 130 and making the volume of the upper tray 130 appear larger.

[0165] In the door frame 3, the game ball B supplied from the supply port 135 in the upper tray 130 first rolls forward in the left side area 131b, then enters the front area 131a and rolls rightward in the front area 131a. The game ball B can be shown to the player as it enters the right side area 131b from the right end of the front area 131a, rolls backward in the right side area 131b, and is then sent out from the delivery port 136 (see FIG. 15). At this time, the game ball B flows through the front area 131a, which is closer to the player on the front side than the door frame performance device 150, so the game ball B in the front area 131a can be easily seen, and the amount of game ball B stored in the upper tray 130 can be easily confirmed.

[0166] In addition, in the door frame 3, the sending outlet 136 is provided at the rear end of the right side region 131b where the game ball B rolls backward in the upper tray 130, so that the sending outlet 136 can be seen from the player side. This allows the player to see the game ball B being sent from the sending outlet 136 (upper tray 130) to the ball launcher 540, which was not possible with previous pachinko machines.

[0167] The pair of lower speakers 153a can be seen through the transparent device cover 151 and the upper wall of the first movable part main body 156 of the door frame 3, and the door frame performance display device 152 can be seen behind the lower speaker 153a. The upper end of the door frame performance display device 152 of the door frame 3 is close to the upper end of the door frame lower unit 100, that is, the lower end of the game window 201. As a result, the door frame performance display device 152 and the performance display device 1600 of the game board 5 are close to each other, so that a performance image can be displayed in which the door frame performance display device 152 and the performance display device 1600 form a single screen.

[0168] In the door frame 3, the lower side of the door frame performance display device 152 arranged behind the performance operation unit 160 is positioned below the upper front end of the performance operation unit 160, and the upper side is positioned above the upper front end of the performance operation unit 160, so that the upper part of the door frame performance display device 152 is higher than the performance operation unit 160. As a result, compared to a case where the entire door frame performance display device 152 is lower than the performance operation unit 160, the door frame performance display device 152 can be easily seen from the player side even if the door frame performance display device 152 is brought close to the performance operation unit 160. In addition, since the depth in the front-rear direction applied to the door frame performance display device 152 can be reduced, the amount of forward bulging of the bulging portion 120 can be suppressed, so that it is possible to avoid giving a feeling of oppression to the player by the bulging portion 120, and it is possible to suppress a decrease in interest by allowing the player to enjoy the game in a comfortable state.

[0169] In addition, the door frame 3 is provided with the door frame performance display device 152 which is positioned diagonally behind the performance operation unit 160 so that the vertical projection range VP of the display screen (the range between the two dotted lines in Figure 11) is close to the performance operation unit 160. Therefore, when the door frame performance display device 152 is viewed from the player's side, the performance operation unit 160 can be seen near the lower outer edge of the door frame performance display device 152. Therefore, by displaying a performance image on the door frame performance display device 152 which decorates the performance operation unit 160, the performance operation unit 160 can be decorated with the performance image, and by changing the performance image the decoration of the performance operation unit 160 can be changed in various ways, making it less likely that the player will get bored.

[0170] Furthermore, because the door frame 3 allows the display screen of the door frame performance display device 152 to be seen near the performance operation unit 160, even if an image of the performance operation unit 160 is not displayed on the door frame performance display device 152, images of arrows, hands, etc. pointing towards the performance operation unit 160 can be displayed to encourage the player to operate the performance operation unit 160. This makes it possible to immediately direct the player's gaze to the performance operation unit 160, making it less likely that the timing of operating the performance operation unit 160 will be delayed, allowing the player to enjoy the player-participation performance of operating the performance operation unit 160 and preventing a decline in interest.

[0171] In addition, due to the lower front speaker grill 192 of the lower front speaker unit 190 and the upper speaker grill of the upper speaker unit 240, the door frame 3 makes it difficult to see the lower front speaker 191 and the upper speaker 241 from the front (player's side) under normal conditions.

[0172] [3-4. Electromagnetic noise countermeasures for door frames] Next, a brief description will be given of noise countermeasures for the door frame 3. As described above, the door frame 3 includes a door frame base unit (not shown) that is rectangular in shape and extends vertically when viewed from the front. As described above, the door frame base unit includes a metal frame-shaped door frame reinforcement unit (not shown) that is attached to the rear side of a door frame base (not shown) that has a game window 201 that penetrates from front to back and is formed into a rectangular shape (rectangle) in shape and extends vertically when viewed from the front, and a metal cylinder lock 127 for opening and closing that is attached to the door frame reinforcement unit. As described above, the door frame reinforcement unit functions as a door frame metal earth in addition to the function of reinforcing the door frame base to provide rigidity, and is electrically connected to a frame earth board 559 provided in the main body frame 4 via a door frame metal earth wire (not shown). That is, in this embodiment, the metal door frame reinforcement unit serves as a frame ground on the door frame side. The frame earth substrate 559 is capable of temporarily collecting electromagnetic noise generated in various locations and grounding (earthing) it to the island equipment of the amusement hall, and is electrically connected to the earth of the island equipment of the amusement hall via an island equipment earth wire not shown.

[0173] As described above, some of the various decorative parts provided on the door frame 3 are not plated at all, while others are plated on the entire front and back. This decorative plating is a precious metal plating such as chrome plating or hard gold plating, and has electrical conductivity. Among the various decorative parts, those plated on the entire front and back are electrically connected to the door frame reinforcement unit via wiring (not shown) or a metal conductive plate (not shown). For this reason, for example, when a player touches a decorative part with decorative plating, static electricity charged to the player is discharged and transmitted as electromagnetic noise from the player to the door frame reinforcement unit via the decorative part, and is then led from the door frame reinforcement unit to the door frame metal earth wire (not shown), the frame earth board 559, and the island equipment earth wire (not shown) to the earth of the island equipment of the game hall, where it is removed.

[0174] When the door frame 3 is closed relative to the main frame 4, as described above, the rotation transmission member of the cylinder lock 127 in the door frame 3 and the transmission cylinder 654 of the locking unit 650 in the main frame 4 come into contact with each other and are electrically connected. Therefore, when a staff member of the game hall or other attendant opens the main frame 4 relative to the outer frame 2 while the door frame 3 is closed relative to the main frame 4, for example, a staff member of the game hall or a person who possesses a setting key (which can change the setting value as well as check the currently set setting value, etc.) can enter the door frame 3 by pressing the key. When a person (a limited number of people) touches the locking unit 650 on the main frame 4, the static electricity charged to the amusement hall staff or other attendant or the person holding the setting key described later is discharged as electromagnetic noise and transmitted from the amusement hall staff or other attendant or the person holding the setting key described later via the locking unit 650 to the door frame reinforcement unit, and from the door frame reinforcement unit via the door frame metal earth wire (not shown), the frame earth board 559, and then the island equipment earth wire (not shown) to the earth of the island equipment of the amusement hall, where it is removed.

[0175] [3-5. Illumination of door frame] Next, the light-emitting effect by the door frame 3 will be described. The door frame 3 surrounds the upper tray 130, the door frame effect device 150, the game window 201, etc. with the bulging upper decorative part 121 and the upper inner decorative part 212 (first circumferential area LA1) which are formed in a milky white cylindrical shape. The multiple LEDs 121a of the bulging upper decorative part 121 and the multiple LEDs 213a of the upper inner decorative part 212 are arranged in a row in the direction in which they each extend. This allows the multiple LEDs 121a and LEDs 213a to be appropriately illuminated to illuminate and decorate the area around the game window 201, etc. At this time, if the multiple LEDs 121a and LEDs 213a are illuminated in sequence, the player can see a light-emitting effect in which light revolves around the game window 201.

[0176] In addition, since the door frame 3 is equipped with an upper outer apex decorative portion 222 and an upper outer valley decorative portion 223 (second peripheral light area LA2) arranged outside the upper inner decorative portion 212, by illuminating and decorating the upper outer apex decorative portion 222 and the upper outer valley decorative portion 223 with the upper outer apex LED 224 and the upper outer valley LED 225, the outside of the first peripheral light area LA1 can be illuminated and decorated, allowing the player to see an illumination effect in which the outside of the game window 201 is illuminated and decorated doubly.

[0177] Since the upper outer apex decorative parts 222 are arranged at intervals in the vertical direction, they can be illuminated one by one from the vertical direction to show the player a light-emitting effect like a level meter. For example, when a chance arrives, the expected value for the game can be shown to the player as a level meter, or a sound meter that matches the output music can be shown to the player.

[0178] In addition, since the upper outer valley decorative portion 223 is formed in a mirror-like shape, by illuminating the upper outer valley LED 225, the spaces between the upper outer peak decorative portions 222 can be made to shine brighter than the upper inner decorative portion 212, and the player can be shown an illuminated effect that can strongly attract the player's attention.

[0179] This door frame 3 is equipped with a plurality of upper outer edge LEDs 231 arranged in a row on the outer edge of the door frame upper unit base 202. By illuminating these upper outer edge LEDs 231, the player can see a light-emitting effect in which the outer edge (third peripheral area LA3) of the door frame 3 is illuminated, which has not been seen in previous pachinko machines 1.

[0180] The door frame 3 has three peripheral light areas on the outside of the game window 201, namely, a first peripheral light area LA1, a second peripheral light area LA2, and a third peripheral light area LA3. By appropriately illuminating each peripheral area, the player can see a variety of light-emitting effects, such as a light-emitting effect that revolves around the game window 201, a light-emitting effect that comes from the outside towards the game window 201, and a light-emitting effect that comes from the game window 201 to the outside.

[0181] In addition, in the door frame 3, by appropriately illuminating the lattice decoration LED 195 of the lower front speaker unit 190 and the lattice decoration LED 245 of the upper speaker unit 240, the lattice portion (lattice decoration portion 194) of the grill decoration frame 193 and the lattice portion (lattice decoration portion 244) of the grill decoration frame 243 can be illuminated and decorated, allowing the player to see an illuminated effect that makes the grill decoration frame 193 of the lower front speaker unit 190 and the grill decoration frame 243 of the upper speaker unit 240 stand out.

[0182] Furthermore, in the door frame 3, by illuminating the lower speaker decorative portion 153c of the lower speaker unit 153, the lattice decorative portion 244 of the upper speaker unit 240, and the upper outer apex LEDs 224 and upper outer valley LEDs 225 located behind the grill decorative frame 243 (upper speaker grill) of the upper speaker unit 240 in the multiple upper outer apex LEDs 224 and upper outer valley LEDs 225, it is possible to illuminate and decorate the space between the pair of lower speakers 153a and the upper wall of the first movable part main body 156, and the space between the upper speaker 241 and the upper speaker grill, allowing players to see an illuminated effect that has not been seen in previous pachinko machines, where the space between the speaker and the speaker grill is illuminated and decorated.

[0183] In addition, since the door frame 3 is provided with a plurality of LEDs 138a of the storage light-emitting decoration section 138 on the rear peripheral wall 133 of the upper tray 130, the upper tray 130 and the game balls B stored in the upper tray 130 can be illuminated and decorated by illuminating the plurality of LEDs 138a. For example, when the game balls B are not stored in the upper tray 130, the plurality of LEDs 138a can be illuminated, and since the inner surface of the upper tray 130 is formed like a mirror, the player can see a light-emitting performance in which the entire upper tray 130 is dazzlingly illuminated and decorated, and the dazzling shining of the upper tray 130 of this pachinko machine 1 strongly attracts the interest of the player who is selecting a pachinko machine to play.

[0184] This storage light-emitting decorative section 138 is located above half the outer diameter of the game ball B from the bottom wall 132 of the upper tray 130, so that when the game ball B is stored in the upper tray 130, the multiple LEDs 138a are illuminated, and the light is irradiated onto the upper half of the game ball B and reflected upward, allowing the player to see an illumination effect in which the game balls B stored in the upper tray 130 sparkle.

[0185] In addition, when the bulge upper decorative part 121 is illuminated, some of the light is also irradiated into the upper tray 130, so that the player can see an illumination effect in which the bulge upper decorative part 121 also illuminates and decorates the upper tray 130 and the game balls B stored in the upper tray 130.

[0186] In addition, the door frame 3 is provided with a light-emitting decorative part 124a surrounding the upper tray ball removal button 124 and a light-emitting decorative part 142a surrounding the lower tray ball removal button 142, so that the upper tray ball removal button 124 and the lower tray ball removal button 142 can be illuminated by illuminating the light-emitting decorative part 124a of the upper tray ball removal button 124 and the light-emitting decorative part 142a of the lower tray ball removal button 142. Therefore, when many game balls B are paid out during a "jackpot" game, by illuminating the upper tray ball removal button 124 and the lower tray ball removal button 142, a light-emitting effect can be shown to encourage the player to operate the upper tray ball removal button 124 and the lower tray ball removal button 142 so as to prevent the upper tray 130 and the lower tray 140 from becoming full of game balls B.

[0187] In this way, the door frame 3 of this embodiment can show the player a variety of light-emitting effects, and by appropriately combining these, a more diverse range of effects can be presented to the player, entertaining the player and preventing them from becoming bored.

[0188] [3-6. Door frame production device] Next, the performance by the door frame performance device 150 of the door frame 3 will be described mainly with reference to Fig. 17 etc. Fig. 17(a) is an explanatory diagram showing a model of the relationship between the door frame performance display device and the performance operation unit in the door frame performance device, (b) is an explanatory diagram showing an example of decoration of the performance operation unit by the performance image of the door frame performance display device, and (c) is an explanatory diagram showing an example of a collaboration performance by the performance image of the door frame performance display device and the movable performance of the performance operation unit.

[0189] In the normal state of the door frame production device 150, the first movable part 155 and the production operation unit 160 are each located at the lower moving end (lowering end). In this state, the upper surface of the first movable part 155 (first movable part main body 156) is located slightly above the upper surface of the device cover 151 through the opening 151a of the device cover 151. In addition, the pressing operation unit 161 of the production operation unit 160 is located slightly above the upper surface of the first movable part main body 156 through the opening 156a of the first movable part main body 156. Even in this normal state, the pressing operation unit 161 of the production operation unit 160 can be pressed.

[0190] In the normal state, when the first LED of the operation unit decoration board 162 is illuminated, the player can see a light-emitting effect in which the upper surface of the pressing operation unit 161 is illuminated and decorated. In addition, in the normal state, when the second LED of the operation unit decoration board 162 is illuminated, the player can see a light-emitting effect in which the opening frame portion 158a of the first movable portion cover 158 surrounding the outside of the pressing operation unit 161 is illuminated and decorated. These light-emitting effects can draw the player's attention to the pressing operation unit 161, and can encourage the player to press the pressing operation unit 161, making it easier for the player to participate in a player-participation type effect in which the player operates the pressing operation unit 161.

[0191] In addition, when the multiple LEDs 159a of the first movable part decorative board 159 are illuminated in the normal state, the space between the rear peripheral wall 133 of the upper tray 130 and the first movable part main body 156 can be illuminated and decorated through the side wall of the first movable part main body 156. In other words, the player can see a lighting effect in which the vicinity of the upper end of the rear peripheral wall 133 of the upper tray 130 is illuminated and decorated.

[0192] In this normal state, when a predetermined sound is output from the pair of lower speakers 153a, the sound is emitted to the player side through the grill hole 151c of the device cover 151 and the grill hole 156b of the first movable part body 156, and the player can hear an acoustic effect in which the sound is heard from the direction of the effect operation unit 160 (press operation unit 161). This makes it possible to attract the player's attention to the press operation unit 161 by the sound from the lower speaker 153a, and to encourage the player to press the press operation unit 161, making it easier for the player to participate in the player-participation type effect of operating the press operation unit 161.

[0193] Furthermore, under normal conditions, the door frame performance device 150 allows the player to see the door frame performance display device 152 in good condition through the device cover 151, and the player can be entertained by the performance image displayed on the door frame performance display device 152 (see Figure 17(a) etc.).

[0194] In the normal state, the door frame effect device 150 can show the player a moving effect in which the first movable part 155 moves to the upper moving end (rising end) together with the effect operation part 160 via the pair of lift arms 174 and lift slider 172 by revolving the first lift pins 175a by the four first lift drive motors 175b of the first lift mechanism 170. As a result, the first movable part 155 pops out upward together with the effect operation part 160, surprising the player and strongly encouraging the player to press the pressing operation part 161, and the first movable part 155 rising can make the player think that something good is going to happen, increasing the player's expectations for the game.

[0195] When the first movable part 155 is moved to the rising end, the side wall of the first movable part body 156 becomes visible from the player side, as shown in Fig. 12(a). In this state, when the multiple LEDs 159a of the first movable part decorative board 159 are illuminated, the player can see a light-emitting effect in which the side wall of the first movable part body 156 is illuminated and decorated. Therefore, when the first movable part 155 is moved from the falling end to the rising end while the side wall of the first movable part body 156 is illuminated and decorated, the player can see an effect in which the first movable part 155 rises from the light, which can give a strong impact to the player.

[0196] In addition, when the first movable part 155 is moved to the raised end and the multiple LEDs 159a on the first movable part decorative substrate 159 are illuminated, some of the light is irradiated onto the game balls B stored in the upper tray 130, so that the multiple LEDs 159a can also be used to show the player an illumination effect that makes the game balls B stored in the upper tray 130 sparkle, thereby achieving the same effect as described above.

[0197] In addition, since the first movable part 155 can be raised and lowered by the four first lifting drive motors 175b, the first movable part 155 can be vibrated by repeatedly rotating the first lifting drive motors 175b in a short forward and reverse direction. In this way, if a player touches the first movable part 155 or the performance operation unit 160 while the first movable part 155 is vibrating, the player can be surprised by the vibration. In addition, if the first movable part 155 is vibrated at the timing of pressing the performance operation unit 160 (pressing operation unit 161), the feeling of the pressing operation can be changed by making it heavier or lighter, which can be entertaining for the player.

[0198] Furthermore, when the first movable part 155 is moved from the lower end to the upper end, the multiple grill holes 156b formed in the upper wall of the first movable part body 156 move upward, and the volume of the space between the multiple grill holes 156b and the pair of lower speakers 153a increases. This changes the volume between the lower speaker 153a and the grill holes 156b, changing the natural vibration of that part and changing the resonance frequency of the sound output from the lower speaker 153a, allowing the player to hear an acoustic effect in which the tone of the sound radiated to the player through the multiple grill holes 156b changes.

[0199] In addition, when the first movable part 155 is moved from the lowering end to the rising end, it appears to the player seated in front of the pachinko machine 1 that the upper part of the first movable part 155 covers the lower part of the display screen of the door frame performance display device 152. As a result, when the first movable part 155 is moved to the rising end, a part of the performance image displayed on the door frame performance display device 152 is blocked by the first movable part 155, so that the player can be made aware of the rise of the first movable part 155, and the same action and effect as above can be achieved.

[0200] At this time, by displaying on the door frame performance display device 152, for example, a performance image in which a specific character lifts up the first movable part 155, or a performance image in which a specific character is lifted up by the rising of the first movable part 155, the player can be shown a collaborative performance made up of the movement performance of the first movable part 155 and the performance image, which can be greatly entertaining to the player.

[0201] In addition, in the normal state, when the second lifting pin 183 is revolved by the second lifting drive motor 182 of the second lifting mechanism 180, the door frame performance device 150 can show the player a moving performance in which the performance operation unit 160 moves to the upper moving end (rising end) via the lifting transmission piece 184. As a result, the upper surface of the pressing operation unit 161 of the performance operation unit 160 is in a state of protruding upward more than the upper surface of the first movable part 155, so that the player's attention can be strongly attracted to the pressing operation unit 161, and the player can be strongly encouraged to press the pressing operation unit 161, and the pressing operation unit 161 can be made to think that something good is going to happen as the pressing operation unit 161 rises, thereby increasing the player's expectations for the game.

[0202] When the performance operation unit 160 is moved to the upper end, the peripheral wall of the operation unit movable base 163 below the pressing operation unit 161 is exposed to the outside, as shown in Fig. 12(b). In this state, when the second LED of the operation unit decoration board 162 is illuminated, the player can see a light-emitting performance in which the peripheral wall of the operation unit movable base 163 is illuminated and decorated. Therefore, when the performance operation unit 160 is moved from the lower end to the upper end while the peripheral wall of the operation unit movable base 163 of the performance operation unit 160 is illuminated and decorated, the player can see a performance in which the performance operation unit 160 is rising from the light, which can give a strong impact to the player.

[0203] In addition, since the second lifting drive motor 182 can raise and lower the performance operation unit 160, the second lifting drive motor 182 can be repeatedly rotated forward and backward in short increments to vibrate the performance operation unit 160. In this way, if a player touches the performance operation unit 160 while it is vibrating, the player can be surprised by the vibration. In addition, by vibrating the performance operation unit 160 at the timing when the performance operation unit 160 (pressing operation unit 161) is pressed, the feeling of the pressing operation can be changed by making it heavier or lighter, which can be entertaining for the player.

[0204] In addition, when the performance operation unit 160 is moved from the lowering end to the rising end, the upper part of the performance operation unit 160 appears to cover the lower part of the display screen of the door frame performance display device 152, when the performance operation unit 160 is moved to the rising end. As a result, when the performance operation unit 160 is moved to the rising end, a part of the performance image displayed on the door frame performance display device 152 is blocked by the performance operation unit 160, so that the player can be made aware of the rise of the performance operation unit 160, and the same action and effect as above can be achieved.

[0205] At this time, by displaying on the door frame performance display device 152, for example, a performance image that decorates the area around the performance operation unit 160 (see Figure 17(b)), a performance image that shows a specified character lifting the performance operation unit 160, a performance image that shows a specified character being lifted by the rising of the performance operation unit 160 (see Figure 17(c)), etc., the player can be shown a collaborative performance made up of the moving performance of the performance operation unit 160 and the performance images, which can be greatly entertaining to the player.

[0206] This performance operation unit 160 can move to the rising end when the first movable part 155 is at the falling end, and can also raise when the first movable part 155 is at the rising end (the state of FIG. 12(b)). For example, by moving the first movable part 155 from the falling end to the rising end and then moving the performance operation unit 160 from the falling end to the rising end, a moving performance in which the performance operation unit 160 rises in two stages can be shown to the player. As a result, since the performance operation unit 160 rises in two stages, it is possible to strongly make the player think that a "jackpot" game will start when the performance operation unit 160 is operated (the special lottery result is a "jackpot"), which can increase the player's expectations for the game, and also allows the player to operate the performance operation unit 160 and enjoy a player-participation type performance.

[0207] In this way, the door frame effect device 150 can present a variety of effects to the player, such as light-emitting effects, moving effects, image effects, player participation effects, sound effects, etc., as described above, and by appropriately combining these, a wider variety of effects can be presented to the player, preventing the player from becoming bored and allowing the player to enjoy the game.

[0208] [3-7. Characteristic Effects of the Present Embodiment] Thus, according to the pachinko machine 1 of this embodiment, the upper tray 130 having the storage area 131 for the game balls B surrounding the device placement section 123 is provided on the upper surface of the bulging portion 120 of the door frame 3 provided in front of and below the game area 5a where the game is played, with the front area 131a on the front side of the device placement section 123 where the door frame performance device 150 is arranged, and the side areas 131b on both the left and right sides. Therefore, the game balls B are stored in the front side of the door frame performance device 150 by the front area 131a, and the game balls B stored in the upper tray 130 can be easily seen by the player. In addition, the two side areas 131b connected by the front area 131a are areas that extend forward and backward, so that the game balls B stored in the side areas 131b in addition to the front area 131a can be easily seen by the player.

[0209] Therefore, by making the game balls B in the upper tray 130 easier to see, the player can be made aware of the amount of stored game balls B. Even if the game balls B in the upper tray 130 are consumed as the game progresses and the amount of stored game balls B decreases, the player can be made to easily recognize the decrease in the amount of stored game balls B and can have game balls B replenished in the upper tray 130. This prevents game balls B from disappearing from the upper tray 130 without the player realizing, prevents sudden interruptions to play, prevents the player from becoming discouraged due to an interruption in play, and suppresses a decrease in the player's interest in the game.

[0210] Furthermore, as described above, the game ball B in the front area 131a and the two side areas 131b can be easily seen by the player, so that the player can instantly recognize whether or not there is game ball B in the front area 131a by simply dropping his or her gaze from the game area 5a to the door frame performance device 150 below. This eliminates the need for the player to carefully check whether or not there is game ball B in the upper tray 130, making it easier for the player to concentrate on the game, making the game more enjoyable and preventing a decline in interest.

[0211] In addition, since the supply port 135 is located on the left side of the two side areas 131b connected by the front area 131a, and the discharge outlet 136 is located on the opposite right side, the front area 131a is located halfway from the supply port 135 to the discharge outlet 136, and the game ball B supplied from the supply port 135 into the storage area 131 passes through the front area 131a and is discharged from the storage area 131 through the discharge outlet 136. Therefore, when the game ball B in the upper tray 130 is consumed by playing a game, the game ball B flows in front of the player (front area 131a), making it easier for the player to recognize the consumption speed and amount of the game ball B, making it easier to achieve the above-mentioned action and effect.

[0212] Furthermore, since the supply port 135 is located on the left side of the side area 131b on both the left and right sides of the device placement section 123, and the discharge port 136 is located on the right side, the distance between the supply port 135 and the discharge port 136 in the left-right direction can be increased, which presumably increases the left-right direction of the storage area 131 as well, thereby making it possible to increase the amount of game balls B that can be stored in the upper tray 130. Therefore, since a large number of game balls B can be stored on the upper tray 130, the player can play without worrying about the amount of stored game balls B, allowing the player to concentrate on the game and enjoy it more. In addition, the player can instantly recognize whether or not there is a game ball B in the front area 131a by simply dropping his or her gaze from the game area 5a to the door frame performance device 150 below, and the player does not need to carefully check whether or not there is a game ball B in the upper tray 130, making it easier for the player to concentrate on the game, making the game more enjoyable and preventing a decline in interest.

[0213] In addition, a storage light-emitting decoration part 138 that irradiates light into the storage area 131 of the upper tray 130 from the bottom surface (bottom wall 132) of the upper tray 130 above half the outer diameter of the game ball B is provided, and light from the LED 138a of the storage light-emitting decoration part 138 is irradiated to a portion above half of the game ball B stored in the storage area 131, so that the light from the storage light-emitting decoration part 138 can be reflected upward by the game ball B. Therefore, the light from the storage light-emitting decoration part 138 can make the game ball B stored in the upper tray 130 sparkle and be illuminating and decorated, allowing the player to enjoy the illuminating decoration of the game ball B and strongly attracting the player's attention to the game ball B stored in the upper tray 130, allowing the player to confirm the amount of game ball B stored in the upper tray 130, and the same action and effect as above can be achieved.

[0214] In addition, since the storage light-emitting decoration part 138 is provided on the rear peripheral wall 133 of the upper tray 130, the LED 138a of the storage light-emitting decoration part 138 is illuminated, and the player can see the light-emitting decoration that has not been seen in previous pachinko machines, in which the rear peripheral wall 133 facing the front of the upper tray 130 is illuminated, which can surprise the player and direct the player's attention to the upper tray 130 (storage area 131), allowing the player to confirm the amount of game balls B stored, thereby ensuring the above-mentioned effect. At this time, since the inner surface of the upper tray 130 is formed in a mirror shape, the light from the storage light-emitting decoration part 138, or the light from the storage light-emitting decoration part 138 reflected by the game balls B, is reflected on the inner surface of the upper tray 130, which can further increase the sparkling feeling in the storage area 131 by the storage light-emitting decoration part 138, and can entertain the player and suppress a decrease in interest.

[0215] In addition, since an alignment section 137 is provided near the outlet 136 to align the game balls B, clogging of the game balls B near the outlet 136 can be prevented, and the game balls B stored in the upper tray 130 can be smoothly sent from the outlet 136 to the ball launcher 540 or the lower tray 140. Therefore, interruption of the game due to clogging of the game balls B can be avoided, allowing the player to enjoy the game and suppressing a decline in interest.

[0216] Furthermore, since the outlet 136 located in the side region 131b of the upper tray 130 can be seen from the front, it is possible to see the game ball B being released from the outlet 136, which was not possible in previous pachinko machines, and this not only surprises the player but also strongly attracts the player's attention, thereby achieving the same effect as described above.

[0217] In addition, since a front area 131a in the storage area 131 in which game ball B is stored is provided on the front side of the device placement section 123, even if game ball B is placed on the door frame performance device 150 provided in the device placement section 123 and rolls forward, it will fall into the front area 131a, thereby preventing game ball B from falling forward from the bulge section 120.

[0218] In addition, since the inner surfaces of the bottom wall 132, rear peripheral wall 133, and front peripheral wall 134 of the upper tray 130 are formed in a mirror-like finish, the game balls B stored in the upper tray 130 are reflected on the peripheral walls of the upper tray 130, giving the player the illusion that game balls B are stored on the other side of the peripheral walls, making it appear as if a large number of game balls B are stored in the upper tray 130.

[0219] In addition, since it is equipped with a storage luminous decorative part 138 that irradiates light into the storage area 131, the light from the storage luminous decorative part 138, or the light from the storage luminous decorative part 138 reflected by the game ball B, is reflected on the inner surface of the upper tray 130, thereby further increasing the sparkling effect in the storage area 131 caused by the storage luminous decorative part 138, entertaining the player and preventing a decline in interest.

[0220] In addition, since the door frame performance device 150 is placed in the device placement section 123 of the bulge section 120, the player can be entertained by the performance provided by the door frame performance device 150, and a decline in the player's interest in the game can be prevented.

[0221] In the above embodiment, the storage area 131 in which the game ball B is stored in the upper tray 130 is shown to be composed of a front area 131a in front of the device placement section 123 (door frame performance device 150) and two side areas 131b on both the left and right sides of the device placement section 123, but this is not limited to this, and may be composed of a front area in front of the device placement section 123, one side area to the left of the device placement section 123, and a back area behind the device placement section 123. Alternatively, it may be composed of a front area 131a in front of the device placement section 123, two side areas 131b on both the left and right sides of the device placement section 123, and a back area behind the device placement section 123 (the device placement section 123 is provided in an island shape within the upper tray 130). The back area of ​​the storage area 131 may be a tunnel shape in which the game ball B is not visible from the player side. In addition, the back area of ​​the storage area 131 may be arranged to pass between the door frame performance display device 152 and the performance operation unit 160 in the door frame performance device 150.

[0222] In addition, in the above embodiment, the upper tray 130 has a mirror-like inner surface, but this is not limited thereto, and the inner surface of the upper tray 130 may be a non-mirror-like surface.

[0223] Furthermore, in the above embodiment, the storage and luminous decorative portion 138 is shown to be provided on the rear peripheral wall 133 of the upper tray 130, but this is not limited to this, and the storage and luminous decorative portion 138 may also be provided on the front peripheral wall 134.

[0224] In addition, in the above embodiment, the first movable part 155 of the door frame performance device 150 is shown to be able to store a certain number of game balls B on the upper surface of the first movable part 155 by the multiple louver portions 158b of the first movable part cover 158, but this is not limited to this, and the upper surface of the door frame performance device 150 may be inclined so that it is lower toward the upper tray 130, and game ball B placed on the upper surface of the door frame performance device 150 may be rolled onto the upper tray 130, so that game ball B is not stored (does not continue to be placed) on the upper surface of the door frame performance device 150.

[0225] [4. Main body frame] The main body frame 4 in the pachinko machine 1 will be described mainly with reference to Fig. 4 and Fig. 18 to Fig. 39.

Therefore, by looking at the traces of opening and closing, it is possible to detect any unauthorized opening and closing of the dispensing control board box 632, thereby increasing the deterrent effect against unauthorized acts against the dispensing control board box 632.

[0245] In addition, the payout control board 633 includes an error LED indicator (not shown) that displays the status of the pachinko machine 1, an RWM clear button 633z having a pressing operation part that serves multiple functions, and the like. In this embodiment, a lead type is used as the RWM clear button 633z, and each lead of the RWM clear button 633z is soldered to the back surface (solder surface) of the payout control board 633. The pressing operation part of the RWM clear button 633z is exposed from an opening formed in the transparent cover body, and the pressing operation part of the RWM clear button 633z can be pressed while the payout control board 633 is housed in the payout control board box 632.

[0246] The RWM clear button 633z has a function as a RAM clear switch for completely erasing information stored in the RAM built in the payout control MPU, which is a microprocessor provided in the payout control board 633, and the RAM built in the main control MPU, which is a microprocessor provided in the main control board that controls the game content (game progress), a function as a setting change button for selecting and switching a setting value, and a function as an error release switch for releasing an error displayed on the error LED indicator. That is, in this embodiment, the setting change function related to the game specifications (function as a setting change button for selecting and switching a setting value) is mounted on the payout control board 633, which is a board separate from the main control board that controls the game content (game progress). In addition, the separate board does not have to be the payout control board 633, and a board that is not stored in a board case, a board stored in a board case, or a board stored in a board case configured as a crimp case is considered. However, since the setting change function (function as a setting change button for selecting and switching setting values) is an important function for a gaming machine, high security is desirable, and a board stored in a board case has higher security than a board not stored in a board case, and a board with even higher security is a board stored in a board case configured as a crimped case. The payout control board 633 is a board stored in a board case configured as a crimped case, so it can be said to have high security. In addition, the main control board 1310 that controls the game content (game progress) is attached to the board holder 1200 attached to the lower rear side of the game panel 1100 as described later, while the payout control board 633 is attached to the main frame 4, which also contributes to improved security.

[0247] The interface unit 620e comprises a board base 634 attached to the left side of the power supply board cover 631 in the power supply unit 620c when viewed from the front, an interface board 635 attached to the rear surface of the board base 634, and an interface board cover 636 attached to the board base 634 so as to cover the rear side of the interface board 635.

[0248] One end of a connection cable extending from the main body frame 4 is connected to the interface board 635. The interface board 635 is connected to the power supply board 630, the payout control board 633, the main control board for controlling the game content (game progress), the peripheral control board for controlling the progress of the performance, etc., and is also connected to a CR unit (not shown) installed outside the pachinko machine 1. The interface board cover 636 extends to the right as viewed from the front beyond the interface board 635 so as to cover a part of the payout control unit 620d.

[0249] The rear cover 640 covers the rear side of the game board 5 that is inserted from the front and attached to the game board attachment portion 301 of the main body frame base 501 of the main body frame base unit 500. The right side of the rear cover 640 in front view is attached to the right end of the rear surface of the main body frame base 501 in front view so as to be rotatable around an axis extending vertically, and the left side of the rear cover in front view is attached to the rear cover attachment portion 551i of the payout base 551 and the rear cover attachment portion 601a of the upper full ball path unit 600 so as to be pivoted openably and closable. A lock screw 642 is provided on the left side of the rear cover 640 in a portion corresponding to the rear cover attachment portion 601a of the upper full ball path unit 600. The left side of the back cover 640 is attached to the back cover attachment portion 551i of the payout base 551 and the back cover attachment portion 601a of the upper full-tank ball path unit 600, and the locking screw 642 is screwed into the back cover attachment portion 601a to fix the back cover 640. The back cover 640 can be rotated about 180 degrees from a closed state in which the back side of the game board 5 is covered to an open state in which the back side of the game board 5 is exposed.

[0250] The rear cover 640 is formed in a shape such that the right side of a flat plate extending vertically and horizontally is bent forward when viewed from the front, and is formed so that the rear surface is positioned on approximately the same plane as the rear surface of the payout base 551 when assembled to the main body frame 4. The rear cover 640 is formed with a plurality of slits 641 for heat dissipation that penetrate from front to back and extend vertically. In this embodiment, the rear cover 640 is formed of a transparent synthetic resin, and the inside of the main body frame 4 can be seen from the rear side of the pachinko machine 1. The slits 641 are not formed at all in an area corresponding to a main control board box (described later) attached to the rear side of the game board 5.

[0251] Incidentally, when the game balls B flow from the ball tank 552 into the tank rail 553, metal powder falls off the game balls B due to wear caused by collisions and rubbing against each other. For this reason, when metal powder generated by wear of the game balls B adheres to the inside of the tank rail 553 on which the game balls B roll downstream, the flow of the game balls B in the downstream direction is impeded, making it difficult to smoothly supply the game balls B downstream, and the payout of the game balls B by the payout device 580 of the payout unit 560 stops.

[0252] Therefore, in this embodiment, multiple cutout portions 553aa are formed on the underside of the tank rail 553 (the underside of the rear surface of the tank rail 553 when looking at the pachinko machine 1 from the front) so that metal powder generated by wear of the game ball B can be removed from the tank rail 553. As a result, for example, metal powder generated by wear of game ball B falls naturally from tank rail 553 to the outside through cutout portion 553aa, and the metal powder can be removed from tank rail 553; metal powder generated by wear of game ball B adhering to the inside of tank rail 553 due to the vibration of game ball B rolling inside tank rail 553 falls from tank rail 553 to the outside through cutout portion 553aa, and the metal powder can be removed from inside tank rail 553 by an attendant such as a game hall staff member inserting a cotton swab into cutout portion 553aa and removing the metal powder generated by wear of game ball B adhering to the inside of tank rail 553.

[0253] In addition, the pachinko machines 1 are arranged in a row in the island equipment of the game hall, back to back, and the game balls B discharged from the pachinko machines 1 are polished by a ball polishing device and then supplied again to the ball tank 552 of the pachinko machine 1 by a ball lifting device, so that the temperature in the island equipment of the game hall is much higher than the temperature inside the game hall. For this reason, the back cover 640 covering the rear side of the game board 5 attached to the main body frame base 501 has multiple heat dissipation slits 641 that penetrate from front to back and extend vertically, as described above, in order to dissipate heat generated from the various boards, electric drive sources such as various motors and various solenoids, and light-emitting means such as various LEDs and various lamps, which are provided on the game board 5, to the outside of the pachinko machine 1. In addition, since the rear cover 640 has multiple slits 641 formed therein, although it is difficult to completely prevent metal powder generated by wear of the game ball B that has fallen through the cutout portion 553aa of the tank rail 553 from penetrating into the rear side of the game board 5, it is possible to inhibit this metal powder from penetrating into the rear side of the game board 5.

[0254] In addition, inside the island equipment of the game hall, multiple types of wiring are suspended from the top for electrically connecting with various connection terminals of the external terminal board 558 of the pachinko machine 1, and there are wiring that is electrically connected to the external terminal board 558 and wiring that is not electrically connected to the external terminal board 558 according to the specifications of the pachinko machine 1. In other words, the wiring that is not electrically connected to the external terminal board 558 becomes unconnected wiring and is in a state of being suspended from the top inside the island equipment of the game hall. Since the pachinko machines 1 are installed in a row facing each other on the island equipment of the game hall, if the unconnected wiring touches various boards provided on the game board 5, electrical drive sources such as various motors and various solenoids, or light-emitting means such as various LEDs and various lamps, a short circuit may occur and cause damage (which may cause a fire). Although the rear cover 640 has multiple slits 641 formed therein, many of the tips of the unconnected wiring are bent at or near the tips, and the tips of the unconnected wiring are caught in the slits 641, making it difficult for them to penetrate toward the rear side of the game board 5, thereby preventing short circuits.

[0255] Among the various boards provided on the game board 5, the boards adjacent to the rear cover 640 (excluding relay boards such as the panel relay board 1410 described later) are covered by a cover body molded from the non-conductive resin that constitutes the board box, and even if the tip of the unconnected wiring penetrates through the slit 641 to the rear side of the game board 5 and comes into contact with the cover body, the boards covered by the cover body will not be affected in any way. The relay boards such as the panel relay board 1410 described later are boards that relay one board and another board, and therefore are an assembly of various connectors, and the wiring patterns for electrically connecting the various connectors are formed not on the surface (mounting surface) of the relay board on which the various connectors are mounted, which is the surface facing the back cover 640, but on the back surface (solder surface) of the relay board, which is the opposite surface facing the back cover 640, and the surface (mounting surface) and back surface (solder surface) of the relay board are solidly painted with a resist of a predetermined color (e.g., green, yellow, red, blue, black, etc.) except for through holes through which pin terminals of various connectors can be inserted and soldered, and the wiring patterns are covered with the resist of the predetermined color and are not exposed. In other words, even if the tip of the unconnected wiring penetrates the back side of the game board 5 through the slit 641 and comes into contact with the relay board, it will not affect the relay board at all.

[0256] In this way, the back cover 640 covering the rear side of the game board 5 attached to the main frame base 501 has the following functions: a protective cover function that can protect the rear side of the game board 5 by covering the rear side of the game board 5; a heat dissipation function that can release heat generated from the various boards, electric drive sources such as various motors and various solenoids, and light-emitting means such as various LEDs and various lamps provided on the game board 5 to the outside of the pachinko machine 1 through the multiple slits 641 by covering the rear side of the game board 5; a metal powder intrusion prevention function that can prevent metal powder generated by wear of the game ball B that has fallen through the cutout portion 553aa of the tank rail 553 from invading the back side of the game board 5; and a protective wall function that can prevent unconnected wiring suspended from inside the island equipment of the game hall from touching the various boards, electric drive sources such as various motors and various solenoids, and light-emitting means such as various LEDs and various lamps provided on the game board 5.

[0257] The locking unit 650 in the main body frame 4 will be described in detail mainly with reference to Fig. 39. Fig. 39(a) is a perspective view of the locking unit of the main body frame seen from the front, and (b) is a perspective view of the locking unit seen from the back. The locking unit 650 is attached to the main body frame base 501 of the main body frame 4, and locks between the main body frame 4 and the door frame 3, and between the main body frame 4 and the outer frame 2. The locking unit 650 comprises a metallic unit base 651 attached to the main frame base 501, a plurality of metallic door frame hooks 652 protruding forward from the unit base 651 and capable of engaging with the door frame 3, a plurality of metallic outer frame hooks 653 protruding rearward from the unit base 651 and capable of engaging with the outer frame 2, a metallic transmission cylinder 654 which moves the door frame hooks 652 or the outer frame hooks 653 in the vertical direction, a metallic lock spring 655 which urges the door frame hooks 652 downward and the outer frame hooks 653 upward, and a metallic outer frame unlocking lever 656 which moves the outer frame hooks 653 downward.

[0258] The main body frame reinforcing frame 530, which is attached to the left side surface of the main body frame base unit 500 as viewed from the front, is attached to the left side surface of the main body frame base 501 of the main body frame base unit 500 as viewed from the front. The main body frame reinforcing frame 530 has a cross-sectional shape in a plan view that is U-shaped with the right side open as viewed from the front, and extends vertically with a constant cross-sectional shape. In this embodiment, the main body frame reinforcing frame 530 is formed from an extruded metal profile.

[0259] When the locking unit 650 is assembled to the main body frame 4, the multiple (three) door frame hooks 652, the transmission cylinder 654, and the outer frame unlocking lever 656 protrude forward from the front surface of the main body frame base 501. The transmission cylinder 654 protrudes forward through the cylinder insertion opening 501f of the main body frame base 501, and by closing the door frame 3 against the main body frame 4, the front end of the transmission cylinder 654 engages with the rotation transmission member 133 of the cylinder lock 130 of the door frame 3, and the rotation of the key inserted in the keyhole 132 is transmitted and rotated. In addition, the locking unit 650 has multiple (three) door frame hooks 652 that are engaged with the hook member 116 of the door frame reinforcement unit 110 in the door frame base unit 100 of the door frame 3, and multiple (two) outer frame hooks 653 that are engaged with the upper hook member 24 and the lower hook member 25 of the outer frame right assembly 20 in the outer frame 2.

[0260] When the locking unit 650 is assembled to the pachinko machine 1, a key corresponding to the keyhole 132 of the cylinder lock 130 is inserted and rotated in a counterclockwise direction as viewed from the front, the multiple door frame hooks 652 move upward via the transmission cylinder 654, and the door frame 3 is unlocked from the main frame 4. On the other hand, when the key is rotated in a clockwise direction as viewed from the front, the multiple outer frame hooks 653 move downward via the transmission cylinder 654, and the main frame 4 is unlocked from the outer frame 2. When the door frame 3 is opened from the main frame 4, the multiple outer frame hooks 653 move downward when the outer frame unlocking lever 656 is slid downward, and the main frame 4 is unlocked from the outer frame 2. In this way, the lock between the main frame 4 and the door frame 3 and between the main frame 4 and the outer frame 2 can be unlocked.

[0261] When locking the space between the main frame 4 and the door frame 3, or between the main frame 4 and the outer frame 2, the tip ends of the door frame hook 652 and the outer frame hook 653 are inclined to become thinner, so that when the door frame 3 is closed against the main frame 4, or the main frame 4 is closed against the outer frame 2, the door frame hook 652 and the outer frame hook 653 move downward or upward to overcome the hook member 116, the upper hook member 24, and the lower hook member 25, and then are locked by the biasing force of the lock spring 655.

[0262] The metallic main body frame reinforcing frame 530 functions as a main body frame metal earth in addition to reinforcing the main body frame base unit 500 and imparting rigidity, and is electrically connected to the above-mentioned frame earth board 559 via a main body frame metal earth wire (not shown). The frame earth board 559 is electrically connected to the earth of the island equipment of the game hall via an island equipment earth wire (not shown). The fact that the metallic main body frame reinforcing frame 530 functions as a main body frame metal earth in addition to reinforcing the main body frame base unit 500 and imparting rigidity will be explained later.

[0263] [4-3. Electromagnetic noise countermeasures for the main frame] Next, a brief explanation will be given of noise countermeasures for the main body frame 4. As described above, the main body frame 4 includes a frame-shaped main body frame base unit 500 whose rear part can be inserted into the outer frame 2 and can support the outer periphery of the game board 5, an inverted L-shaped payout base unit 550 attached along the upper and left sides in front view at the rear side of the main body frame base unit 500, a payout unit 560 for paying out game balls B received by the payout base unit 550 to the player side (upper tray 130 and lower tray 140), a power supply board 630 equipped with a power switch 630a capable of powering on the pachinko machine 1, and a board unit 620 having a payout control board 633.

[0264] As described above, the main body frame base unit 500 is formed of a metal extrusion material and includes a main body frame reinforcing frame 530 attached to the left side of the main body frame base 501 when viewed from the front. As described above, the main body frame reinforcing frame 530 functions as a main body frame metal ground in addition to the function of reinforcing the main body frame base unit 500 to provide rigidity, and is electrically connected to the above-mentioned frame ground board 559 provided on the main body frame 4 via a main body frame metal ground wire (not shown). That is, in this embodiment, the metal main body frame reinforcing frame 530 serves as the frame ground on the main body frame side. In addition, the ball tank 552 has a metal plate (not shown) arranged on the entire bottom part thereof, which is electrically connected to the above-mentioned frame ground board 559 via a ball tank ground wire (not shown). In addition, the ground connection terminal (not shown) provided on the interface board 635 in the board unit 620 is electrically connected to the above-mentioned frame ground board 559 via an interface ground wire (not shown). In addition, the ground connection terminal (not shown) provided on the power supply board 630 in the board unit 620 is electrically connected to the above-mentioned frame ground board 559 via a power supply ground wire (not shown). This frame earth substrate 559 is electrically connected to the earth of the island equipment of the gaming hall via an island equipment earth wire not shown.

[0265] In this way, as a noise countermeasure for the main body frame 4, electromagnetic noise that has entered the main body frame reinforcement frame 530, the ball tank 552, the interface board 635 in the board unit 620, and the power supply board 630 in the board unit 620 is removed by being guided from the main body frame reinforcement frame 530, the ball tank 552, the interface board 635 in the board unit 620, and the power supply board 630 in the board unit 620 through various corresponding earth wires (not shown), the frame earth board 559, and the island equipment earth wire (not shown) to the earth of the island equipment of the amusement hall.

[0266] [4-4. Frame ground board] Next, the frame earth board 559 will be briefly described. As described above, the frame earth board 559 is capable of collecting electromagnetic noise generated at various places and grounding (earthing) it to the island equipment of the game hall, and is provided with a plurality of earth terminals. The first earth terminal (interface earth terminal) is electrically connected as an interface earth to an earth connection terminal provided on the interface board 635 in the board unit 620 of the main body frame 4 via an interface earth wire (not shown), the second earth terminal (island equipment earth terminal) is electrically connected as an island equipment earth to an earth connection terminal in the island equipment of the game hall via an island equipment earth wire (not shown), the third earth terminal (ball tank earth terminal) is a ball tank earth to which one end of a ball tank earth wire (not shown) is attached by a metal screw (not shown) to a metal plate (not shown) arranged on the entire bottom of the ball tank 552, and the other end of this ball tank earth wire is electrically connected, and the fourth earth terminal (main body frame metal earth terminal) is electrically connected to ...main body frame metal earth terminal) is electrically connected to the island equipment of the game hall via an island equipment earth wire (not shown), the third earth terminal (main body frame metal earth terminal) is electrically connected to the island equipment of the game hall via an island equipment earth wire (not shown), the third earth terminal (main body frame metal earth terminal) is electrically connected to the island equipment of the game hall via an island equipment earth wire (not shown), the third earth terminal (main body frame metal earth terminal) is electrically connected to the island equipment of the game hall via an island equipment earth wire (not shown the fifth earth terminal (power supply earth terminal) serves as a power supply earth and is electrically connected to an earth connection terminal provided on the power supply board 630 in the board unit 620 of the main body frame 4 via a power supply earth wire (not shown); and the sixth earth terminal (door frame metal earth) serves as a door frame metal earth and is electrically connected to a metal door frame reinforcement unit in the door frame base unit 500 of the door frame 3 via a metal screw (not shown) at one end of a door frame metal earth wire (not shown), and the other end of the door frame metal earth wire is electrically connected.

[0267] In the circuit of the frame earth board 559, the third earth terminal (sphere tank earth terminal) as the sphere tank earth is electrically connected to one end of a first resistor (not shown), the other end of the first resistor is electrically connected to the fifth earth terminal (power supply earth terminal) as the power supply earth, the second earth terminal (island equipment earth terminal) as the island equipment earth, and the first earth terminal (interface earth terminal) as the interface earth, respectively, and the fourth earth terminal (main body frame metal earth terminal) as the main frame metal earth and the sixth earth terminal (door frame metal earth) as the door frame metal earth are electrically connected to one end of a second resistor (not shown), and the other end of the second resistor is electrically connected to the fifth earth terminal (power supply earth terminal) as the power supply earth, the second earth terminal (island equipment earth terminal) as the island equipment earth, and the first earth terminal (interface earth terminal) as the interface earth, respectively. In other words, the other end of the first resistor and the other end of the second resistor are electrically connected. In this embodiment, 510 ohms (Ω) and 2 watts (W) are adopted as the first resistor and the second resistor.

[0268] Electromagnetic noise flowing into the first earth terminal (interface earth terminal) as an interface earth is conducted to the earth of the island equipment of the game hall via the second earth terminal (island equipment earth terminal) as the island equipment earth and the island equipment earth wire, and is eliminated. Electromagnetic noise flowing into the third earth terminal (ball tank earth terminal) as the ball tank earth is conducted to the earth of the island equipment of the game hall via the second earth terminal (island equipment earth terminal) as the island equipment earth and the island equipment earth wire, and is eliminated. Electromagnetic noise flowing into the fourth earth terminal (main frame metal earth terminal) as the main frame metal earth is conducted to the island equipment earth and the island equipment earth wire, and is eliminated. The electromagnetic noise flowing to the fifth earth terminal (power supply earth terminal) as a power supply earth is conducted via the second earth terminal (island equipment earth terminal) as the island equipment earth and the island equipment earth wire to the earth of the island equipment of the amusement hall and removed, and the electromagnetic noise flowing to the sixth earth terminal (door frame metal earth) as the door frame metal earth is conducted via the second earth terminal (island equipment earth terminal) as the island equipment earth and the island equipment earth wire to the earth of the island equipment of the amusement hall and removed.

[0269] Meanwhile, the payout base unit 550 in the main body frame 4 is fitted with a ball tank 552, a payout unit 560 and the like. The ball tank 552 is supplied with game balls B from the island equipment of the game hall, and the ball tank 552 supplies the game balls B to the payout unit 560. The game balls B are polished in the island equipment of the game hall, and rub against each other during circulation between the island equipment and the pachinko machine 1, becoming charged and discharging static electricity, thereby emitting electromagnetic noise. For this reason, static electricity is likely to accumulate in the area where the ball tank 552 and the payout unit 560, which can store the game balls B, and the surrounding area.

[0270] Therefore, in this embodiment, a frame earth substrate 559 is placed near the ball tank 552 and payout unit 560, which are prone to static electricity accumulation, and for the ball tank 552 and the metal main body frame reinforcement frame 530 in the main body frame base unit 500 of the main body frame 4, which are prone to static electricity accumulation and are therefore strongly affected by electromagnetic noise, the frame earth substrate 559 is designed to gradually attenuate and flow electromagnetic noise through the first resistor and the second resistor, respectively, to the third earth terminal (ball tank earth terminal) as a ball tank earth and the fourth earth terminal (main body frame metal earth terminal) as a main body frame metal earth, thereby suppressing instantaneous discharge of high voltage, and to lead the noise from the second earth terminal (island equipment earth terminal) as an island equipment earth to the earth of the island equipment of the amusement hall via the island equipment earth wire. In other words, electromagnetic noise that has invaded from the ball tank 552 and the payout unit 560, which are prone to accumulate static electricity, can be removed by leading it to the ground of the island equipment of the game hall from the frame ground board 559 via the ball tank 552 and the metal main frame reinforcement frame 530 as a frame ground called the frame ground, and then to the ground of the island equipment of the game hall. Thus, in this embodiment, the metal main frame reinforcement frame 530 functions as a main frame metal ground in addition to reinforcing the main frame base unit 500 and providing it with rigidity.

[0271] As described above, some of the various decorative parts provided on the door frame 3 are plated on the entire front and back sides. This decorative plating is a precious metal plating such as chrome plating or hard gold plating, and has electrical conductivity. The decorative part with this decorative plating is electrically connected to the door frame reinforcement unit in the door frame base unit (not shown) of the door frame 3 via wiring (not shown) or a metal conductive plate (not shown). For this reason, for example, when a player touches a decorative part with decorative plating, static electricity charged to the player is discharged and transmitted as electromagnetic noise from the player to the door frame reinforcement unit via the decorative part. In addition, when an attendant such as a game hall clerk or a person possessing a setting key described later (a limited number of people who can check the current setting values ​​in addition to changing the setting values) touches the locking unit 650 on the main frame 4, as described above, the static electricity charged to the game hall clerk or the person possessing the setting key described later is discharged as electromagnetic noise and is transmitted from the game hall clerk or the person possessing the setting key described later to the door frame reinforcement unit via the locking unit 650.

[0272] Therefore, in this embodiment, for the door frame reinforcement unit in the door frame base unit (not shown) of the door frame 3, in the frame earth board 559, the sixth earth terminal (door frame metal earth) as the door frame metal earth is connected via a second resistor to gradually flow and attenuate electromagnetic noise, thereby suppressing instantaneous discharge of high voltage, and can be led from the second earth terminal (island equipment earth terminal) as the island equipment earth to the earth of the island equipment of the amusement hall via an island equipment earth wire. In other words, electromagnetic noise from decorative parts with decorative plating, players, staff such as skill hall clerks, and persons possessing the setting key described below (limited persons who can check the current setting values ​​in addition to changing the setting values) can be removed by directing it to the earth of the island equipment of the amusement hall through the door frame reinforcement unit from the frame earth board 559 as a frame earth called a frame ground.

[0273] [4-5.Details of the upper part of the main frame] Next, the detailed configuration of the upper part of the main body frame 4 will be described in detail mainly with reference to Figs. 40 to 47. Fig. 40(a) is a plan view of the main body frame, and (b) is a cross-sectional view cut along line BB in (a). Fig. 41 is an enlarged view of the upper part in a perspective view of the main body frame seen from the rear. Fig. 42(a) is a perspective view seen from the front and above in a state in which the tank rail and the like are assembled to the ball tank, and (b) is a perspective view of (a) seen from the front and below. Fig. 43 is an exploded perspective view seen from the front of Fig. 42(a). Fig. 44 is an explanatory diagram showing an area through which game balls overflowing from the ball tank in the upper part of the main body frame flow. Fig. 45 is an explanatory diagram showing the flow of game balls overflowing from the ball tank in the upper part of the main body frame. Fig. 46 is an explanatory diagram showing the flow of game balls to the bypass passage in the upper part of the main body frame. Fig. 47 is an enlarged view showing the vicinity of the tank rail in a perspective view of the main body frame seen from the rear of the hinge side.

[0274] As described above, the main body frame 4 is made up of a frame-shaped main body frame base 501 whose rear portion can be inserted into the outer frame 2 and which is detachably and hinge-rotatably attached to the outer frame 2 by the main body frame upper hinge portion 510 and the main body frame lower hinge portion 520, and which can support the outer periphery of the game board 5; an inverted L-shaped payout base 551 attached along the upper and left sides in a front view at the rear side of the main body frame base 501; a ball tank 552 attached to the payout base 551, which is box-shaped (container-shaped) extending to the left and right and which is open upward; and a tank 552 attached to the left side of the ball tank 552, which is groove-shaped and open upward and extends to the left. It comprises a rail 553, a first rail cover 554 attached to part of the upper end of the tank rail 553, a second rail cover 555 attached to the upper end of the tank rail 553, spaced apart from the first rail cover 554 to the left when viewed from the front, a ball straightening member 556 attached to the upper end of the tank rail 553 at a position between the first rail cover 554 and the second rail cover 555, a ball stopping member 557 attached to the downstream end of the tank rail 553, and a payout device 580 attached to the downstream side of the tank rail 553 behind the payout base 551 for paying out game balls B to the player.

[0275] The ball tank 552 has a rectangular shape extending in the left-right direction in plan view, a bottom wall 552a inclined so that the left side is lower in front view, a front wall 552b and a rear wall 552c extending upward from the front and rear sides of the bottom wall 552a, respectively, and a left wall 552d and a right wall 552e extending upward from both the left and right sides of the bottom wall 552a, respectively, and is formed in a container shape with an open top. The ball tank 552 stores game balls B supplied from an island facility such as a game hall where the pachinko machine 1 is installed.

[0276] The spherical tank 552 also has an overflow section 552f that is cut out from above in the front wall 552b and formed lower than the remaining outer circumferential upper edge. This overflow section 552f is formed over approximately 3 / 4 of the left-right length of the front wall 552b from the end side of the left side wall 552d to the end side on the opposite side (the right side wall 552e side).

[0277] The right end (upstream side) of the tank rail 553 communicates with the inside of the ball tank 552 in front view, and the downstream side extends to one side (left side) in the left-right direction so as to move away from the ball tank 552. The tank rail 553 has a gutter-shaped main guide section 553a that extends from the vicinity of the upstream to the downstream end at the bottom and is formed so that only one game ball B can flow in the width direction perpendicular to the flow direction of the game ball B. The main guide section 553a is inclined so as to become lower as it approaches the left side when viewed from the front. In addition, the main guide section 553a is formed in a crank shape that extends from the right end side to a position that is about 1 / 10 of the total length in the left-right direction in a plan view, parallel to the axis extending from the right end side to the left in the left-right direction, and then extends diagonally from the right end to a position that is about 4 / 10 of the total length in the left-right direction so as to move backward as it approaches the left, and then extends from there to the left end in parallel to the axis extending in the left-right direction.

[0278] In the main guide section 553a, the tank rail 553 has a section extending parallel to the axis extending in the left-right direction from the left end to the right, which extends to the upper end with the same width, and the upper side is closed by attaching the first rail cover 554, the second rail cover 555, and the ball flow straightening member 556 to the upper end of this section. Also, in the section where the upper side is closed, the tank rail 553 is formed so that the height of the flow path through which the game ball B flows becomes lower toward the downstream end (left end), and at the downstream end, it is formed at a height (slightly higher than the outer diameter of the game ball B) that allows only one game ball B to flow.

[0279] In addition, in the tank rail 553, three rectangular cutouts 553aa having a predetermined length (about 30 mm in this embodiment) in the left-right direction are formed at predetermined intervals (about 10 mm in this embodiment) on the bottom surface of the trough-shaped main guide section 553a and the rear wall of the main guide section 553a in a front view at a portion where the upper side is closed. The rectangular cutouts 553aa form a rectangular hole having a length of about 30 mm in the left-right direction and a height of about 7 mm plus the thickness of the rear wall (about 2.5 mm in this embodiment) from the rear wall of the main guide section 553a toward the front in the bottom surface of the main guide section 553a, and a rectangular hole having a length of about 30 mm in the left-right direction and a height of about 7 mm plus the thickness of the bottom plate of the bottom surface (about 2.5 mm in this embodiment) from the bottom surface of the main guide section 553a toward the top in the rear wall of the main guide section 553a, and these rectangular holes are formed in communication with each other.

[0280] When the game balls B flow from the ball tank 552 into the tank rail 553, metal powder falls off the game balls B due to wear caused by collisions and rubbing against each other. Therefore, when metal powder caused by wear of the game balls B adheres to the main guide portion 553a, the flow of the game balls B in the downstream direction is impeded, making it difficult to smoothly supply the game balls B toward the downstream side, and the payout of the game balls B by the payout device 580 stops.

[0281] Therefore, in this embodiment, a plurality of cutout portions 553aa are formed in the main guiding portion 553a, and it is configured so that metal powder generated by wear of the game ball B can be removed from the main guiding portion 553a. As a result, for example, metal powder generated by wear of game ball B falls naturally from main guide portion 553a to the outside through cutout portion 553aa, and the metal powder can be removed from main guide portion 553a by allowing metal powder generated by wear of game ball B adhering to main guide portion 553a due to the vibration of game ball B rolling around main guide portion 553a to fall from main guide portion 553a to the outside through cutout portion 553aa, and the metal powder can be removed from main guide portion 553a by having an attendant such as a game hall staff member insert a cotton swab into cutout portion 553aa and remove the metal powder generated by wear of game ball B adhering to main guide portion 553a.

[0282] The tank rail 553 extends from the upstream end to a portion where the upper side is closed above the main guide portion 553a, and has a bulging portion 553b that bulges out wider than the width of the main guide portion 553a so that multiple game balls B are lined up in the width direction perpendicular to the flow direction of the game balls B, and narrows in the width direction from the upstream end to the downstream side so as to match the width of the main guide portion 553a. This bulging portion 553b allows multiple game balls B that were wide in the width direction on the upstream side to be aligned so that the width direction becomes the width of one game ball B as they move downstream. The bulging portion 553b is also formed so that the width direction becomes narrower as they move from the upper end side to the lower main guide portion 553a. As a result, the tank rail 553 can align multiple game balls B flowing through the bulging portion 553b so that they are aligned in a line in the width direction as they move downstream and downward.

[0283] The bulging portion 553b of the tank rail 553 has a center of curvature located on the inner side and is formed into a three-dimensionally curved shape. Since the center of curvature of the bulging portion 553b is located above the main guiding portion 553a, a slightly chamfered corner is formed at the boundary between the main guiding portion 553a and the bulging portion 553b in the tank rail 553. In addition, the bulging portion 553b is formed with a larger curvature on the downstream side than on the upstream side. For this reason, in the game ball B flowing through the three-dimensionally curved bulging portion 553b, the direction in which the reaction force from the bulging portion 553b side acts changes in various directions depending on the position of the bulging portion 553b that the game ball B abuts against, and the occurrence of ball jamming in the bulging portion 553b can be suppressed. In more detail, when the bulging portion 553b is formed into a shape that extends uniformly, a reaction force always acts on the game ball B circulating inside the bulging portion 553b from the inner surface of the bulging portion 553b in a uniform direction, and the reaction force is difficult to disperse, so that the game ball B inside is always pushed in a uniform direction, making it difficult for the game ball B to escape and making ball jamming (ball jamming) more likely to occur. On the other hand, since the bulging portion 553b is a three-dimensional curved surface, the direction of the reaction force acting from the inner surface of the bulging portion 553b varies depending on the position of the game ball B, and the pushing direction of the multiple game balls B circulating inside is dispersed, making it easier for the pushed game ball B to escape and making it difficult for ball jamming (ball jamming) to occur.

[0284] In addition, the tank rail 553 is molded from a transparent material (polycarbonate resin, etc.) and is configured so that the inside can be seen from the outside. As a result, even if ball clogging (ball jamming) occurs in the tank rail 553, the state of the game balls B in the tank rail 553 can be seen from the outside, so the location where the balls are jammed can be quickly identified. Therefore, ball clogging in the tank rail 553 can be quickly eliminated, so that the interruption of the game due to the occurrence of ball clogging can be shortened as much as possible, and the decrease in the interest of the player in the game due to the interruption of the game can be suppressed. In addition, since the tank rail 553 is made transparent, the rear side (back unit 3000) of the game board 5 attached to the main frame 4 can be seen from the rear through the tank rail 553, so that when a malfunction occurs in the movable performance unit of the game board 5, the state of the transmission mechanism such as the drive motor, gears, and belts can be confirmed with the game board 5 attached to the main frame 4, and the same effect as the above-mentioned mutual effect can be achieved.

[0285] The main frame 4 is provided in front of the ball tank 552, extends in the front-to-rear direction, and extends outward (to the left) from the left side wall 552d of the ball tank 552 on the same side as the downstream side of the tank rail 553 in the left-right direction (the left side when viewed from the front).It is equipped with an overflow surface portion 501m whose rear end side is at the same height as the overflow portion 552f and inclined so that the front end side is higher in order to return the game balls B that have overflowed forward from the ball tank 552 to the ball tank 552, and a bypass passage 552g which extends rearward from the outside of the left side wall 552d of the ball tank 552 at the rear end of the overflow surface portion 501m to above the bulge portion 553b whose upper side is open on the tank rail 553, inclined so that the rear end side is lower, and inclined so that the side away from the ball tank 552 in the left-right direction (the left side) is lower, and which guides some of the game balls B that have overflowed from the ball tank 552 to the overflow surface portion 501m.

[0286] The main frame 4 also includes a discharge portion 551j which is provided on both the left and right outer sides of the bypass passage 552g, opposite the left side wall 552d of the ball tank 552, and which has a left-right spacing wider than the outer diameter of the game ball and a bottom height lower than the portion of the tank rail 553 which is open at the top, an external terminal board 558 which is provided on the opposite side of the bypass passage 552g across the discharge portion 551j, at a position lower than the overflow surface portion 501m, and which has a plurality of wire connection terminals 558a to which electrical wiring can be connected from the rear, and a terminal cover 551k which covers the upper sides of the multiple wire connection terminals 558a (external terminal board 558) and whose upper surface extends horizontally at a position higher than the overflow surface portion 501m.

[0287] The overflow surface portion 501m is formed on the main body frame base 501. The overflow surface portion 501m extends rearward in a flat plate shape from a position that is two to four times the outer diameter of the game ball B lower than the upper edge of the rear surface of the base main body 501a, which is formed in a rectangular shape extending vertically when viewed from the front. The overflow surface portion 501m is formed with a length in the left-right direction that is about 1 / 3 of the length of the left-right direction of the main body frame base 501, and the left end when viewed from the front is located to the right of 1 / 3 of the total length in the left-right direction from the left end of the main body frame base 501. The overflow surface portion 501m is formed with a height from the front end to the rear end that is about 1 / 2 the height of the outer diameter of the game ball B. When the main body frame 4 is closed to the outer frame 2, a gap of about twice the outer diameter of the game ball B is formed between this overflow surface portion 501m and the outer frame upper member 30.

[0288] The main frame base 501 is disposed on both the left and right sides of the overflow surface portion 501m, and has a flat left step portion 501n and a right step portion 501o that extend substantially horizontally at the same height as the front end of the overflow surface portion 501m, and a plurality of ribs 501p that extend in a strip-like manner in the front-rear direction on both the left and right outer sides of the left step portion 501n and the right step portion 501o with their upper ends higher than the left step portion 501n and the right step portion 501o, and are arranged in a row in the left-right direction at intervals narrower than the outer diameter of the game ball B. The left step portion 501n is formed so that its left-right length is shorter than its front-rear length. The left step portion 501n is also inclined so that its rear right corner is slightly lower than the horizontal plane when viewed from the front. The right step portion 501o is formed so that its left-right length is longer than its front-rear length. The right step portion 501o is also inclined so that its rear left corner is slightly lower than the horizontal plane when viewed from the front.

[0289] The multiple ribs 501p of the main frame base 501 are formed higher than the upper surface of the terminal cover 551k, and when the main frame 4 is closed against the outer frame 2, the gap between the outer frame 2 and the lower surface of the outer frame upper member 30 is formed at a height narrower than the outer diameter of the game ball B.

[0290] When the main frame base 501 is assembled to the main frame 4, when viewed from the front, the right end of the overflow surface portion 501m is aligned in the left-right direction with the right end of the overflow portion 552f of the spherical tank 552, the left end of the overflow surface portion 501m is aligned in the left-right direction with the left end of the bypass passage 552g, and the right end of the right stage portion 501o is aligned in the left-right direction with the right side wall 552e of the spherical tank 552.

[0291] The bypass passage 552g is formed integrally with the spherical tank 552. In the following, the container-like area surrounded by the bottom wall 552a, the front wall 552b, the rear wall 552c, the left side wall 552d, and the right side wall 552e is also simply referred to as the spherical tank 552. The bypass passage 552g has a passage surface 552h that extends leftward from the outside of the left side wall 552d of the spherical tank 552 in a flat plate shape, with the front end at the same height as the overflow portion 552f and the rear end inclined downward, and a weir portion that extends upward from the end edge of the passage surface 552h opposite the left side wall 552d to the same height as the left side wall 552d. The left end side (the weir portion 552i side) of the rear end edge of the passage surface 552h of the bypass passage 552g in the front view extends rearward to the same position as the rear wall 552c of the ball tank 552, and extends obliquely so as to move forward from the left end side toward the right end side. Note that the inclination in the left-right direction of the passage surface 552h of the bypass passage 552g may be horizontal.

[0292] When assembled to the main body frame 4, the rear end of the bypass passage 552g extends along the front end of the portion of the tank rail 553 that extends in a crank shape in the left-right direction and that extends obliquely with respect to the left-right direction. That is, the rear end of the bypass passage 552g extends obliquely with respect to the left-right direction. As a result, the flow direction of the game ball B guided rearward by the bypass passage 552g changes from the oblique rear end to a direction perpendicular to the oblique rear end. The obliquely extending rear end of the bypass passage 552g extends approximately parallel (the flow direction of the game ball B in the tank rail 553) to the obliquely extending portion of the tank rail 553. Therefore, the game ball B is released from the rear end of the bypass passage 552g in a direction approximately perpendicular to the flow direction (width direction) of the tank rail 553, so that the game ball B from the bypass passage 552g can be received at a wide portion of the tank rail 553. In addition, since the game balls B are supplied from the bypass passage 552g into the tank rail 553 in a direction approximately perpendicular (at right angles) to the flow direction of the game balls B, it is possible to prevent the game balls B from the bypass passage 552g from clogging the tank rail 553.

[0293] The bypass passage 552g extends diagonally in the left-right direction so that its rear end moves rearward as it approaches the downstream side of the tank rail 553. Therefore, when the game ball B is released from the bypass passage 552g toward the tank rail 553, the diagonally extending rear end allows the game ball B to be released toward the upstream side, which is wider than the downstream side, where the tank rail 553 is narrower, and by releasing the game ball B into the wider section, the occurrence of ball jamming within the tank rail 553 can be suppressed.

[0294] In addition, the portion of the tank rail 553 where the game ball B is guided by the bypass passage 552g corresponds to the rear of the left side wall 552d of the ball tank 552 and the outside of the left portion of the rear wall 552c when viewed from the front. In this portion, the game ball B that passes under the guide surface portion 552j of the ball tank 552 (the ceiling side of the opening 552k) from inside the ball tank 552 flows. For this reason, in the portion of the tank rail 553 behind the bypass passage 552g, the height of the multiple game balls B stacked up in the vertical direction does not exceed the height of the ceiling of the opening 552k (the height of the wall of the tank rail 553). Therefore, space (empty space) can be secured on the downstream side of the ball tank 552 on the tank rail 553, that is, on the rear end side of the bypass passage 552g, allowing the game balls B to be stacked upwards, so that the game balls B guided rearward by the bypass passage 552g can be reliably received by the tank rail 553, and the game balls B will not spill rearward from the tank rail 553.

[0295] The spherical tank 552 has a flat guide surface portion 552j that extends from a position slightly lower than the overflow portion 552f of the left side wall 552d to the right, on the inside surrounded by the front wall 552b, the rear wall 552c, and the left side wall 552d. The guide surface portion 552j extends in the front-rear direction from the front wall 552b to the rear wall 552c. In addition, when viewed from the front, the right end edge of the guide surface portion 552j is formed in a shape such that, when viewed from the front, the right end edge extends diagonally rearward from a position from the left end of the front wall 552b to a position that is approximately 1 / 3 of the total length of the front wall 552b in the left-right direction, from the left end of the front wall 552b to a position that is approximately 1 / 9 of the total length of the front wall 552b in the left-right direction, and from there, the right end edge extends parallel to the left side wall 552d to the vicinity of the rear wall 552c, and from there, the right end edge extends parallel to the rear wall 552c with a constant width in the front-to-back direction from the left end of the rear wall 552c to a position that is approximately 1 / 3 of the total length of the rear wall 552c in the left-to-right direction.

[0296] The spherical tank 552 has an opening 552k formed so as to penetrate the area surrounded by the right end edge of the guide surface portion 552j formed in the above-mentioned shape and a straight line connecting the end of the right end edge on the front wall 552b side and the end on the rear wall 552c side in the vertical direction. The spherical tank 552 also has a flat flange portion 552l extending outward in the left-right direction and in the vertical direction on the same plane as the front wall 552b at the front end side of the right side wall 552e and the front end side of the weir portion 552i of the bypass passage 552g. The upper edge of the part of the front wall 552b excluding the overflow portion 552f and the upper edge of the two flange portions 552l are formed higher than the upper edge of the left side wall 552d and the rear wall 552c (the upper surfaces of the left step portion 501n and the right step portion 501o of the main body frame base 501).

[0297] When the spherical tank 552 and the tank rail 553 are assembled together, the upstream end (the right end in front view) of the tank rail 553 is connected to the opening 552k of the spherical tank 552. In addition, the diagonally extending portion of the tank rail 553, which extends left and right in a crank shape in a plan view, and the portion extending straight left and right on the left side of that are located (protruding) rearward from the spherical tank 552. The rear end edge of the left bypass passage 552g of the left side wall 552d of the spherical tank 552 is located at the front end of the diagonally extending portion of the tank rail 553, which extends left and right in a crank shape in a plan view.

[0298] The discharge portion 551j is formed on the upper surface of the dispensing base 551. When assembled to the main body frame 4, the discharge portion 551j extends rearward from the rear side of the flange portion 552l on the left side as viewed from the front of the ball tank 552 to the tank rail 553 so as to lower in a stepped manner rearward from a height lower than the bypass passage 552g to the same height as the bottom wall 552a of the ball tank 552, and then extends leftward along the tank rail 553 to a position higher than the upper end of the tank rail 553 (a position near the center in the left-right direction of the second rail cover 555), and then extends rearward.

[0299] The external terminal board 558 has a plurality of electric wire connection terminals 558a attached to the rear surface in a state where they are lined up in the left-right direction. The electric wire connection terminal 558a is a one-touch terminal whose gripping portion opens by operating a lever to grip the tip of an electric wire. When the external terminal board 558 is assembled to the main body frame 4, the upper side of the tank rail 553 is disposed in front of the portion closed by the first rail cover 554, the second rail cover 555, and the ball straightening member 556. The terminal cover 551k that covers the upper side of the external terminal board 558 (the plurality of electric wire connection terminals 558a) is formed on the upper surface of the dispensing base 551. The upper surface of the terminal cover 551k is formed at approximately the same height as the upper end of the flange portion 552l of the ball tank 552.

[0300] Next, the effect of the upper part of the main body frame 4 in the pachinko machine 1 will be described. First, as shown by the white arrows in FIG. 44, the overflow surface portion 501m, the left step portion 501n, the right step portion 501o, and the bypass passage 552g are inclined so that the rear end side of the overflow surface portion 501m and the bypass passage 552g are lower, and the rear right corner of the left step portion 501n and the rear left corner of the right step portion 501o are lower. Also, the bottom wall 552a and the tank rail 553 (main guide portion 553a) of the ball tank 552 are inclined so that the left end side is lower when viewed from the front. Also, the guide surface portion 552j of the ball tank 552 is inclined so that the right end side in the opposite direction to the bottom wall 552a is lower.

[0301] Then, when the amount of game balls B stored in the ball tank 552 increases due to supply from the island equipment, they can first flow out to the outside (front) of the ball tank 552 over the overflow part 552f, which is the lowest height among the outer circumferential upper end edges, and the game balls B that overflow from the ball tank 552 can be released to the overflow surface part 501m, and the game balls B that flow out from the ball tank 552 to the front overflow surface part 501m can be returned to the ball tank 552 by the inclination of the overflow surface part 501m (see FIG. 45). Therefore, since it is possible to prevent any further increase in the game balls B in the ball tank 552, it is possible to suppress the game balls B from strongly pushing against each other in the ball tank 552 (increase in ball pressure), and it is possible to prevent the occurrence of clogging (so-called ball jamming) due to the meshing of the game balls B in the ball tank 552.

[0302] In addition, since the bypass passage 552g is provided, as shown in FIG. 46, the game balls B that have overflowed from the ball tank 552 to the overflow surface portion 501m can be sent to the tank rail 553 via the bypass passage 552g. This makes it possible to avoid the game balls B in the ball tank 552 from applying a strong backward pressing force to the game balls B in the ball tank 552 due to the game balls B that have accumulated in the overflow surface portion 501m, and prevents the game balls B from clogging in the ball tank 552. In addition, since the game balls B can be sent to the tank rail 553 via the bypass passage 552g, it is possible to prevent the game balls B that have overflowed from the ball tank 552 or the overflow surface portion 501m from spilling out to the outside (rear side) of the main body frame 4. Therefore, it is possible to avoid the occurrence of a malfunction in which the game balls B that have spilled out to the outside of the main body frame 4 are pinched between the outer frame 2 and the main body frame 4, making it impossible to open or close the main body frame 4.

[0303] Furthermore, some of the game balls B that have overflowed from the ball tank 552 onto the overflow surface 501m can be guided to the downstream side of the tank rail 553 by the bypass passage 552g, and the game balls B can be sent to the tank rail 553 from a certain position along the left side away from the ball tank 552.Therefore, the flow (pressure) of the game balls B sent to the tank rail 553 by the bypass passage 552g can be directed toward the downstream side of the tank rail 553, thereby preventing the game balls B from pushing against each other too strongly within the tank rail 553 and preventing the game balls B from clogging.

[0304] In addition, at the outer circumferential upper edge of the ball tank 552, the height of the remaining upper edge other than the overflow portion 552f is made higher than the overflow portion 552f, so that the upper edge of the left side wall 552d on one side of the ball tank 552 in the left-right direction between the ball tank 552 and the bypass passage 552g is higher than the overflow portion 552f, that is, the rear end of the overflow surface portion 501m. As a result, the game ball B that overflows from the ball tank 552 over the overflow portion 552f and overflows into the overflow surface portion 501m and flows from the overflow surface portion 501m to the bypass passage 552g is blocked by the left side wall 552d on one side of the ball tank 552, so that it is possible to prevent the game ball B from returning from the bypass passage 552g to the ball tank 552 side, and it is possible to prevent the game ball B on the bypass passage 552g side from pressing the game ball B in the ball tank 552 and causing clogging of the game ball B in the ball tank 552.

[0305] Furthermore, as described above, the upper edge of the left side wall 552d between the ball tank 552 and the bypass passage 552g is higher than the rear end of the overflow surface portion 501m (passage surface 552h on which the game ball B rolls in the bypass passage 552g), so that the game ball B can be prevented from overflowing from the ball tank 552 to the bypass passage 552g without passing through the overflow surface portion 501m. This prevents the game ball B from flowing in from the side (ball tank 552) into the bypass passage 552g, so that the flow of the game ball B in the bypass passage 552g can be made to flow in a constant direction from the overflow surface portion 501m on the front end side to the tank rail 553 on the rear end side, and the pressure of the game ball B guided from the bypass passage 552g to the tank rail 553 can be made to be in a constant direction. Therefore, within the tank rail 553, the direction of pressure applied to the game balls B becomes inconsistent, which prevents the game balls B from pushing against each other and becoming stuck, thereby preventing the game balls B from becoming jammed.

[0306] In addition, since the bottom of the tank rail 553 is provided with the main guide section 553a extending to the downstream end, the game balls B in the tank rail 553 are aligned in a line in the left-right direction when they reach the main guide section 553a, so that the game balls B in the tank rail 553 can be aligned and the game balls B can be reliably guided to the downstream payout device 580. In addition, since the tank rail 553 is provided with a wide bulge section 553b in which multiple game balls B can be aligned in the portion where the upper side is open, the game balls B released from the rear end of the bypass passage 552g can be reliably received and the above-mentioned action and effect can be reliably achieved.

[0307] In addition, the bulging portion 553b of the tank rail 553 extends from the upstream end to the portion where the upper side is closed, and the width direction narrows from the upstream end toward the downstream side to match the width of the main guide portion 553a, so that the multiple game balls B can be aligned in a line in the width direction as they move downstream in the bulging portion 553b. In addition, the portion where the upper side of the tank rail 553 is closed is formed so that the height of the flow path through which the game balls B flow decreases toward the downstream end, so that the multiple game balls B that were stacked in multiple stages in the height direction on the upstream side (ball tank 552 side) can be aligned in a line by circulating them downstream through the portion where the upper side of the tank rail 553 is closed. Therefore, the tank rail 553 can guide the multiple game balls B in a line aligned in a line to the downstream side (dispensing device 580 side).

[0308] Furthermore, since it is equipped with overflow surface portion 501m and bypass passage 552g, it is possible to store a certain number of game balls B therein, and since tank rail 553 is equipped with bulge portion 553b, the volume inside tank rail 553 can be increased, so that more game balls B can be stored in combination with ball tank 552.

[0309] In addition, on the opposite side of the ball tank 552, with the bypass passage 552g and the discharge section 551j in between, there is an external terminal board 558 having multiple wire connection terminals 558a to which electrical wiring is connected, and a terminal cover 551k covering the upper side of the multiple wire connection terminals 558a (external terminal board 558).Therefore, the wire connection terminals 558a and the terminal cover 551k can be placed far away from the ball tank 552 to which the game balls B are supplied from the island equipment.As a result, even if the game balls B supplied from the island equipment bounce or are supplied with force at the ball tank 552 or the overflow surface section 501m, it is difficult for them to reach (contact) the wire connection terminals 558a, etc., and no malfunctions such as a short circuit or loosening of electrical wiring due to the game balls B contacting them will occur.

[0310] In addition, since the multiple wire connection terminals 558a face rearward and the upper surface of the terminal cover 551k is higher than the overflow surface 501m, even if the game ball B supplied from the island equipment to the ball tank 552 bounces off the ball tank 552 or the overflow surface 501m, it is difficult for it to land on the upper surface of the terminal cover 551k. Even if the game ball B does land on the upper surface of the terminal cover 551k, it is difficult for it to fall from the rear side, making it easier to avoid the occurrence of the above-mentioned problems.

[0311] Furthermore, the game ball B returned from the overflow surface portion 501m to the guide surface portion 552j of the ball tank 552 is sent to the upstream side of the ball tank 552 (to the right in FIG. 45) due to the inclination of the guide surface portion 552j. This makes it possible to prevent the game ball B on the guide surface portion 552j from pressing the game ball B in the ball tank 552 in the downstream direction, and makes it possible to prevent clogging of the game ball B in the ball tank 552.

[0312] Furthermore, even if the game ball B supplied to the ball tank 552 from the island equipment bounces off the ball tank 552 or the overflow surface 501m and lands on the left step 501n or the right step 501o on both sides of the overflow surface 501m, as shown in Figure 45, the slope of these elements can guide the game ball B to the overflow surface 501m or the bypass passage 552g, preventing malfunctions caused by the game ball B spilling outside the main frame 4.

[0313] In addition, since the game balls B pass under the guide surface portion 552j when they flow from the ball tank 552 to the tank rail 553 side, the amount (height) of the game balls B stacked on the upper side of the tank rail 553 can be restricted by the guide surface portion 552j so that it does not exceed the lower surface of the guide surface portion 552j. Therefore, a space (empty space) capable of stacking the game balls B on the upper side can be secured on the downstream side of the ball tank 552 (guide surface portion 552j) on the tank rail 553, that is, on the rear end side of the bypass passage 552g, and the game balls B guided by the bypass passage 552g can be reliably received.

[0314] Furthermore, since the multiple wire connection terminals 558a and the terminal cover 551k are positioned in front of the portion of the tank rail 553 whose upper side is closed, even if the game ball B falls rearward from the terminal cover 551k, the game ball B will not be received by the tank rail 553, thereby preventing the game ball B from affecting the game ball B inside the tank rail 553 and causing a malfunction.

[0315] In addition, the ball tank 552 is made of an electric conductor (in this example, it is molded from a synthetic resin having electrical conductivity), whereas the tank rail 553 and the peripheral control board box of the peripheral control unit 1500 described later are made of an insulator (in this example, it is molded from a synthetic resin having electrical conductivity). In this embodiment, when the tank rail 553 and the peripheral control board box are charged, they have the same polarity, so that when the metal powder of the game ball B attached to the tank rail 553 falls from the cutout portion 553aa, it adheres to the peripheral control board box of the same polarity as the tank rail 553. That is, the metal powder of the game ball B does not adhere to the ball tank 552, but moves to the tank rail 553, adheres to the tank rail 553, and remains inside the tank rail 553, and when the metal powder of the game ball B attached to the tank rail 553 falls from the cutout portion 553aa, it adheres to the peripheral control board box of the same polarity as the tank rail 553 (for example, the upper surface of the peripheral board box).

[0316] [4-6. Composition of measures against metal powder] Next, a description will be given of a configuration of a metal powder countermeasure that can avoid electrical trouble (short circuit) caused by metal powder of game balls B that have fallen to the outside from main guide portion 553a through multiple cutout portions 553aa formed in trough-shaped main guide portion 553a of tank rail 553, with reference to Fig. 48. Fig. 48 is an enlarged schematic diagram showing a part of the cross section cut along line CC in Fig. 40(a), and shows an overview of the configuration of the metal powder countermeasure.

[0317] As described above, if the metal powder (foreign matter) of the game ball B that falls from the notches 553aa formed in the trough-shaped main guide portion 553a of the tank rail 553 adheres to the peripheral control unit 1500 arranged below the tank rail 553, electrical trouble occurs, causing malfunctions or other problems in the peripheral control unit 1500. For example, the peripheral control board 1510 of the peripheral control unit 1500 is equipped with ICs such as a peripheral control IC, ROM, and SDRAM, which will be described later, and the peripheral data ROM board is equipped with ICs such as a peripheral data ROM, which will be described later. The pin spacing of these ICs is becoming smaller, and the pin spacing of various connectors and special connectors provided on the peripheral control board 1510 is becoming narrower, and the number of connectors on the peripheral control board 1510 is increasing, which is narrowing the spacing between the various connectors, and the spacing between the connectors and the special connectors is also narrowing, so it is necessary to take measures against electrical troubles caused by foreign matter that falls from the tank rail.

[0318] First, the multiple cutout portions 553aa formed in the gutter-shaped main guide portion 553a of the tank rail 553 are positioned, as shown in FIG. 48, offset rearward (in this embodiment, offset by a distance dimension approximately half the diameter of the game ball B) compared to the cover body 1501 of the peripheral control unit 1500 attached to the rear side of the game panel 1100 of the game board 5 (the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of the rear unit 3000).

[0319] As described above, the cross-sectional shape in the front-rear direction of the top plate portion 551a of the payout base 551 on which the tank rail 553 is arranged is formed in a stepped shape with multiple bends downward from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a). In the example shown in Fig. 48, the first eaves portion 551da is extended rearward of the pachinko machine 1 so that the lower end of the top plate portion is substantially flush with the rear surface of the tank rail 553. In addition, when the rear cover 640 is assembled to the main body frame 4, the upper end of the rear cover 640 is in face-to-face contact with the rear surface of the first eaves portion 551da.

[0320] As a result, the metal powder of the game ball B that has fallen to the outside from the main guiding part 553a through the cutout part 553aa can be received and adhered to the first eaves part 551da of the top plate part 551a. That is, the first eaves part 551da of the top plate part 551a prevents the metal powder of the game ball B that has fallen to the outside from the main guiding part 553a through the cutout part 553aa from falling toward the cover body 1501 of the peripheral control unit 1500 and the base body 1502, and further prevents the metal powder of the game ball B that has fallen to the outside from the main guiding part 553a through the cutout part 553aa from entering the cover body 1501 of the peripheral control unit 1500, thereby preventing the occurrence of electrical trouble caused by the metal powder of the game ball B adhering to the peripheral control board 1510.

[0321] In the pachinko machine 1 of this example, further, in a state where the back cover 640 is assembled to the main body frame 4, the back cover 640 extends downward from the abutting portion with the first overhanging portion 551da so as to cover at least a part of the rear of the cover body 1501 of the peripheral control unit 1500. Therefore, when metal powder of the game ball B that has fallen to the outside from the main guide portion 553a through the cutout portion 553aa and adhered to the first overhanging portion 551da of the top plate portion 551a falls from the first overhanging portion 551da of the top plate portion 551a, the metal powder is prevented from being attracted to the rear side (back unit) of the game panel 1100 of the game board 5. It is possible to prevent the game ball B from falling toward the cover body 1501 of the peripheral control unit 1500 attached to the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of the knit 3000) and the base body 1502, and thereby prevent metal powder of the game ball B that has fallen from the first eaves portion 551da of the top plate portion 551a from entering the cover body 1501 of the peripheral control unit 1500, thereby preventing the occurrence of electrical problems caused by metal powder of the game ball B adhering to the peripheral control board 1510.

[0322] In this way, the top plate 551a of the payout base 551 and the back cover 640 function as a eaves or cover (covering) that can prevent metal powder of the game ball B that has fallen from the main guide part 553a to the outside through the cutout parts 553aa formed in the main guide part 553a from falling toward the peripheral control unit 1500 attached to the rear side of the game panel 1100 of the game board 5 (the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of the rear unit 3000). Therefore, electrical trouble caused by metal powder of the game ball B from the tank rail 553 can be prevented.

[0323] In addition, in the pachinko machine 1 of this example, a first eaves portion 551da is provided below the cutout portion 553aa, so that not only when the rear cover 640 is closed but also when the rear cover 640 is opened, metal powder of the game ball B that has fallen to the outside from the main guiding portion 553a through the cutout portion 553aa can be received and adhered to the first eaves portion 551da, and the metal powder of the game ball B that has fallen to the outside from the main guiding portion 553a through the cutout portion 553aa is prevented from falling toward the cover body 1501 and base body 1502 of the peripheral control unit 1500, and thus the metal powder of the game ball B that has fallen to the outside from the main guiding portion 553a through the cutout portion 553aa is prevented from entering the cover body 1501 of the peripheral control unit 1500, thereby preventing electrical trouble caused by the metal powder of the game ball B adhering to the peripheral control board 1510.

[0324] In the above example, when assembled to the main body frame 4, the upper end of the rear cover 640 is in contact with the rear surface of the first overhanging portion 551da, but the upper end of the rear cover 640 and the first overhanging portion 551da may be arranged apart from each other. That is, the arrangement of the rear cover 640 and the first overhanging portion 551da does not matter as long as the rear cover 640 and the first overhanging portion 551da cooperate to prevent metal powder of the game ball B that has fallen to the outside from the main guiding portion 553a through the cutout portion 553aa from entering the cover body 1501 of the peripheral control unit 1500.

[0325] In addition, in this embodiment, the cutout portions 553aa formed in multiple positions in the gutter-shaped main guide portion 553a of the tank rail 553 and the cover body 1501 of the peripheral control unit 1500 attached to the rear side of the game panel 1100 of the game board 5 (the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of the rear unit 3000) are offset in the front-to-rear direction of the pachinko machine 1 (in this embodiment, offset by a distance dimension that is approximately half the diameter of the game ball B) (in other words, the structure is such that the peripheral control unit 1500 is not positioned directly below the cutout portions 553aa), which is effective in preventing electrical trouble caused by metal powder from the game ball B from the tank rail 553.

[0326] In addition, the multiple ventilation holes 1501az formed in the cover body 1501 are provided on the rear surface of the cover body 1501 (the cover plate described later), but are not provided on each cover side wall provided on the upper, left, lower, and right sides of the cover body 1501 (the cover plate described later). Therefore, even if metal powder from the game ball B adheres to the upper wall of the cover body 1501 (the cover side wall formed on the upper side of the cover plate described later), it is difficult for the metal powder to enter the inside of the cover body 1501.

[0327] In addition, a plurality of ventilation holes 1501az may be formed in any one or a combination of cover side walls 1501b to 1501e provided on the upper side, left side, lower side, and right side of the cover flat plate of the cover body 1501, except for the cover side wall 1501b provided on the upper side. For example, a plurality of ventilation holes 1501az may be formed only in the cover side wall 1501c provided on the left side, a plurality of ventilation holes 1501az may be formed only in the cover side wall 1501d provided on the lower side, a plurality of ventilation holes 1501az may be formed only in the cover side wall 1501e provided on the right side, or a plurality of ventilation holes 1501az may be formed in a combination of cover side walls 1501c to 1501e provided on the cover flat plate 1510a, left side, lower side, and right side. Even with this configuration, it is possible to prevent foreign matter (e.g., metal powder generated by wear of the game ball B) generated by the game ball B from falling and invading through the ventilation hole 1501az toward the inside of the peripheral control board box 1505. This makes it possible to prevent electrical trouble caused by foreign matter falling onto various boards of the peripheral control board box 1505. Therefore, it is possible to prevent electrical trouble caused by foreign matter falling from the tank rail 553. The reason why the ventilation hole 1501az is not formed in the cover side wall 1501b provided on the upper side is that if the ventilation hole 1501az is formed in the cover side wall 1501b provided on the upper side, the probability of electrical trouble caused by foreign matter falling onto various boards of the peripheral control board box 1505 increases because foreign matter (e.g., metal powder generated by wear of the game ball B) generated by the game ball B falls and invades through the ventilation hole 1501az toward the inside of the peripheral control board box 1505.

[0328] Furthermore, when no ventilation holes 1501 are provided on the top surface of the cover body 1501, the heat dissipation function may be compensated for by increasing the number of ventilation holes 1501 provided on other surfaces or by expanding the area of ​​the ventilation holes 1501. This can contribute to suppressing the temperature rise of the peripheral control board box 1505, and can suppress the occurrence of electrical troubles such as thermal runaway.

[0329] In addition, the upper surface of the cover body 1501 is in a substantially horizontal state when attached to the pachinko machine 1. Therefore, when the metal powder of the game ball B falls from the main guide portion 553a to the outside through the cutout portion 553aa and adheres to the upper surface of the cover body 1501, the metal powder can be retained on the upper surface of the cover body 1501. This can prevent the metal powder of the game ball B from entering the inside of the cover body 1501. Note that a part or all of the upper surface of the cover body 1501 may be inclined as long as it does not cause the metal powder of the game ball B to fall toward the ventilation hole 1501az formed in the cover body 1501.

[0330] Furthermore, the first overhanging member 551a disposed below the tank rail 553 may be attached to the top plate portion 551a as a separate member (separate structural component).

[0331] In addition, in cases where the upper part or rear of the cover body 1501 of the peripheral control unit 1500 is covered by the first eaves portion 551da and / or the rear cover 640 of the top plate portion 551a, or where the multiple cutout portions 553aa formed in the gutter-shaped main guide portion 553a of the tank rail 553 and the cover body 1501 of the peripheral control unit 1500 are positioned offset in the front-to-rear direction of the pachinko machine 1, and there is a low probability that metal powder of the game ball B that has fallen to the outside from the main guide portion 553a will head toward the cover body 1501 of the peripheral control unit 1500 through the multiple cutout portions 553aa formed in the main guide portion 553a, ventilation holes 1501az may be provided in a part of the upper surface of the cover body 1501 when attached to the pachinko machine 1 (for example, a corner of the cover body 1501; most of the upper surface of the cover body 1501 is closed but ventilation holes 1501az are formed in part of it, etc.).

[0332] Furthermore, this technical idea is not limited to completely preventing metal powder of game ball B that has fallen to the outside from main guiding portion 553a through cutout portion 553aa from entering into cover body 1501 of peripheral control unit 1500, but may be sufficient as long as it suppresses metal powder of game ball B that has fallen to the outside from main guiding portion 553a through cutout portion 553aa from entering into cover body 1501 of peripheral control unit 1500 compared to conventional pachinko machines, and for example, providing ventilation holes 1501az in part of the upper surface of cover body 1501 when attached to pachinko machine 1 (for example, corners of cover body 1501; most of the upper surface of cover body 1501 is closed but part of it has ventilation holes 1501az formed therein, etc.).

[0333] Further, a plurality of slit holes are formed in the cover body 1501 of the peripheral control unit 1500. Further, along the lower side of the cover body 1501, seven connector holes and a volume adjustment hole are formed at positions corresponding to seven connectors and a volume adjustment switch, which will be described later, provided on the peripheral control board 1510 attached to the inside of the cover body 1501, and two connector holes are formed at positions corresponding to two connectors provided on the liquid crystal output board, which will be described later. When the peripheral control board 1510 is attached to the inside of the cover body 1501, gaps are formed between the seven connectors provided on the peripheral control board 1510 and the seven connector holes formed in the cover body 1501, and the seven connectors provided on the peripheral control board 1510 are exposed from these seven connector holes, and a gap is formed between the volume adjustment switch provided on the peripheral control board 1510 and the volume adjustment hole formed in the cover body 1501, and the volume adjustment switch provided on the peripheral control board 1510 is exposed from this volume adjustment hole. In addition, when the liquid crystal output board described later is attached inside the cover body 1501, gaps are formed between the two connectors on the liquid crystal output board and the two connector holes formed in the cover body 1501, and the two connectors on the liquid crystal output board are exposed from these two connector holes.

[0334] The cover body 1501 in the peripheral control unit 1500 takes in air from outside the peripheral control unit 1500 through multiple ventilation holes 1501az formed in the cover body 1501, and multiple ventilation holes 1540az formed in the shield plate 1540 housed in the space between the cover body 1501 and the base body 1502, and also through the gaps mentioned above (gaps formed between the seven connectors on the peripheral control board 1510 and the seven connector holes formed in the cover body 1501, gaps formed between the volume adjustment switch on the peripheral control board 1510 and the volume adjustment hole formed in the cover body 1501, and gaps formed between the two connectors on the liquid crystal output board and two connector holes formed in the cover body 1501).

[0335] Incidentally, when the cover body 1501 of the peripheral control unit 1500 takes in air from outside the peripheral control unit 1500, there is a high probability that the heavy metal powder of the game ball B will be influenced by the air flow and sucked into the inner space of the cover body 1501, and the sucked in metal powder will cause an electrical problem (short circuit) and cause malfunctions (failures) in various electronic components mounted on various boards such as the peripheral data ROM board 1520 and the liquid crystal output board 1530 attached to the inside of the cover body 1501.

[0336] In the pachinko machine 1 of this example, in order to prevent such electrical trouble (short circuit), a first eaves portion 551da is formed along the upper side of the cover body 1501 in the peripheral control unit 1500, so that the peripheral control unit 1500 can be configured to function as an eaves that prevents heavy powder, such as metal powder of the game ball B, from being sucked into the cover body 1501 of the peripheral control unit 1500 through the ventilation holes 1501az formed in the cover body 1501. The configuration of the peripheral control unit 1500 will be described in detail later.

[0337] In the above-described embodiment, a plurality of cutouts 553aa are formed in the main guide portion 553a in the tank rail 553 so that metal powder generated by wear of the game ball B can be removed from the main guide portion 553a, but a single cutout, hole, or groove similar to the cutout 553aa may be formed in the ball passage in which the game ball B rolls. Specifically, in the ball guide unit 570 having a single guide passage 570a that guides the game ball B from the tank rail 553 downward in a serpentine manner as shown in FIG. 33, a cutout, hole, or groove that can remove metal powder of the game ball B in the guide passage 570a to the outside from the guide passage 570a can be formed on the rear surface of the guide unit base 571 of the guide unit 570 shown in FIG. 28. As shown in Fig. 33, below the ball guiding unit 570, the payout device 580 and the board unit 620 are arranged, and the payout device 580 has a board on which the blade rotation detection sensor 590 is mounted, and the board unit 620 has a power board 630, a payout control board 633, an interface board 635, etc. shown in Fig. 34, and various boards are arranged. For this reason, when a cutout, hole, or groove is formed on the rear surface of the induction unit base 571, it is necessary to prevent metal powder of the game ball B that falls through the cutout, hole, or groove formed on the rear surface of the induction unit base 571 from adhering to various boards arranged below the induction unit 570. Therefore, a canopy-like member can be formed to protrude rearward along the upper edge of dispensing device rear cover 582 of dispensing device 580 shown in Figure 27, or the position of the cutout, hole, or groove formed on the rear surface of induction unit base 571 can be shifted from the position of various boards such as the board on which blade rotation detection sensor 590 is mounted in dispensing device 580, or a configuration can be adopted using both.In addition, a configuration can be made by forming a eave-like member protruding toward the rear along the upper edges of the power supply board cover 631 of the power supply board 630, the dispensing control board box 632 of the dispensing control board 633, and the interface board cover 636 of the interface board 635 shown in Figure 34, and the positions of the cutouts, holes, or grooves formed on the rear surface of the induction unit base 571 can be shifted from the positions of the power supply board cover 631, the dispensing control board box 632, and the interface board cover 636, or a configuration can be made by adopting both.

[0338] Next, another configuration of the present invention (hereinafter, referred to as "configuration of metal powder countermeasures according to the second to fifth embodiments") in which a countermeasure against metal powder is taken to avoid electrical trouble caused by metal powder of the game ball B will be described with reference to Figs. 49 to 51. Fig. 49 shows the configuration of the countermeasure against metal powder according to the second embodiment, and is a schematic diagram of the configuration of the countermeasure against metal powder according to the second embodiment. Fig. 50 shows the configuration of the countermeasure against metal powder according to the third embodiment, and is a schematic diagram of the configuration of the countermeasure against metal powder according to the third embodiment. Fig. 51 shows the configuration of the countermeasure against metal powder according to the fourth embodiment, and is a schematic diagram of the configuration of the countermeasure against metal powder according to the fourth embodiment. In Figs. 49 to 51, members having the same functions as those in the embodiment shown in Fig. 48 (hereinafter, referred to as "configuration of the countermeasure against metal powder according to the first embodiment") are denoted by the same reference numerals, the outer shape of the game board 5 is shown by solid lines, and only the parts of the game board 5 necessary for explanation are shown as cross-sectional views.

[0339] [Comparison between the configuration of the first embodiment against metal powder and the configuration of the second embodiment against metal powder] In the configuration for preventing metal powder in the first embodiment, the cross-sectional shape in the front-to-rear direction of the top plate portion 551a on which the tank rail 553 is arranged is formed in a stepped shape with multiple downward bends as it moves from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a), as described above, and forms a first eaves portion 551da extended rearward of the pachinko machine 1 so that the lower end of this top plate portion 551a is approximately flush with the rear surface of the tank rail 553.

[0340] In contrast, in the configuration for preventing metal powder in the second embodiment, as shown in FIG. 49, the cross-sectional shape in the front-to-rear direction of the top plate portion 551a on which the tank rail 553 is arranged is formed in a stepped shape with multiple downward bends as it moves from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a), and the lower end of the top plate portion 551a forms a first eaves portion 551da extended to the rear of the pachinko machine 1, but the first eaves portion 551da is not extended so as to be approximately flush with the rear surface of the tank rail 553, but only up to that point (in the front of the pachinko machine 1) (in the example shown in FIG. 48, up to just below the cutout portion 553aa formed in the gutter-shaped main guide portion 553a of the tank rail 553).

[0341] On the other hand, the upper end of the back cover 640, when assembled to the main body frame 4, bends toward the front side of the pachinko machine 1 (toward the game board 5) and forms a second eaves portion 640a that extends to just below the notch portion 553aa formed in the gutter-shaped main guide portion 553a of the tank rail 553, and this second eaves portion 640a is in contact with the first eaves portion 551da of the top plate portion 551a. Also, the rear end surface of the back cover 640 is arranged further rearward of the pachinko machine 1 than the rear surface of the tank rail 553.

[0342] Thus, the configuration for preventing metal powder in the first embodiment differs in that the first overhanging portion 551da alone forms the overhanging portion, whereas the configuration for preventing metal powder in the second embodiment differs in that the first overhanging portion 551da and the second overhanging portion 640a are connected to jointly form the overhanging portion.

[0343] In addition, as long as the first overhanging portion 551da and the second overhanging portion 640a are connected to jointly form the overhanging portion, the length of the first overhanging portion 551da and the second overhanging portion 640a, i.e., the proportion of each in the overhanging portion and the position where the first overhanging portion 551da and the second overhanging portion 640a are abutted are not limited to the above. For example, the first overhanging portion 640a may be extended to the vicinity of the front surface of the tank rail 553, and the second overhanging portion 640a may be extended to the vicinity of the front surface of the tank rail 553 to abut against the first overhanging portion 640a (abutting on the same surface as the front surface of the tank rail 553), so that metal powder of the game ball B that has fallen to the outside from the main guide portion 553a through the cutout portion 553aa is mainly received and adhered to the second overhanging portion 640a.

[0344] The configuration of the metal powder countermeasure according to the second embodiment can also achieve the same effect as the configuration of the metal powder countermeasure according to the first embodiment. That is, the metal powder of the game ball B that falls to the outside from the main guide portion 553a through the cutout portions 553aa formed in the main guide portion 553a can be received and adhered to the first overhanging portion 551da arranged below the tank rail 553, or received and adhered to the second overhanging portion 640a of the rear cover 640. Furthermore, since the rear surface of the rear cover 640 is extended to cover at least a part of the rear of the cover body 1501 of the peripheral control unit 1500 when assembled to the main frame 4, when metal powder of the game ball B that has fallen to the outside from the main guide portion 553a through the cutout portion 553aa and adhered to the first overhanging portion 551da of the top plate portion 551a or the second overhanging portion 640a of the rear cover 640 falls from the first overhanging portion 551da of the top plate portion 551a or the second overhanging portion 640a of the rear cover 640, the metal powder is prevented from falling onto the rear side of the game panel 1100 of the game board 5 (the rear unit 3 The purpose of this is to prevent game ball B from falling toward the cover body 1501 of the peripheral control unit 1500 attached to the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of .000), and toward the base body 1502, and thereby to prevent metal powder of game ball B that has fallen to the outside from the main guiding portion 553a via the cutout portion 553aa from entering the cover body 1501 of the peripheral control unit 1500, thereby preventing electrical problems from occurring due to metal powder of game ball B adhering to the peripheral control board 1510.

[0345] [Comparison between the configuration of measures against metal powder according to the first embodiment and the configuration of measures against metal powder according to the third embodiment] In the configuration for preventing metal powder in the first embodiment, the cross-sectional shape in the front-to-rear direction of the top plate portion 551a on which the tank rail 553 is arranged is formed in a stepped shape with multiple downward bends as it moves from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a) as described above, and a first eaves portion 551da is formed extending rearward from the pachinko machine 1 so that the lower end of this top plate portion 551a is approximately on the same plane as the rear surface of the tank rail 553, and a rear cover 640 is provided behind the cover body 1501 of the peripheral control unit 1500 without the top plate portion 551a.

[0346] In contrast, in the configuration of the metal powder countermeasure according to the third embodiment, as shown in Fig. 50, when the tank rail 553 is attached to the top plate portion 551a, the first eaves portion 551da is disposed below the tank rail 553, and the rear end portion of the top plate portion 551a is bent downward to form an extended back plate upper portion 551d. The lower end portion of this back plate upper portion 551d is in a state of abutting against the upper end portion of the rear cover 640. Note that the length of the back plate upper portion 551d is not limited to the example shown in Fig. 50, and it may be extended to a position covering the immediate rear of the cover body 1501 of the peripheral control unit 1500, or it may be extended above that position without extending to a position covering the immediate rear of the cover body 1501 of the peripheral control unit 1500 as shown in Fig. 50.

[0347] Thus, the metal powder countermeasure configuration of the first embodiment differs in that the rear cover 640 alone covers at least a portion of the rear of the cover body 1501 of the peripheral control unit 1500, whereas the metal powder countermeasure configuration of the second embodiment differs in that the upper part of the back panel 551d and the rear cover 640 are connected to jointly cover at least a portion of the rear of the cover body 1501 of the peripheral control unit 1500.

[0348] The configuration of the metal powder countermeasure according to the third embodiment can also achieve the same effect as the configuration of the metal powder countermeasure according to the first embodiment. That is, the metal powder of the game ball B that falls to the outside from the main guide portion 553a through the cutout portions 553aa formed in the main guide portion 553a can be received and adhered to the first overhanging portion 551da arranged below the tank rail 553, or received and adhered to the second overhanging portion 640a of the rear cover 640. Furthermore, when assembled to the main body frame 4, the upper part 551d of the back plate and the rear surface of the rear cover 640 are connected to jointly cover at least a part of the rear of the cover body 1501 of the peripheral control unit 1500. Therefore, when metal powder of the game ball B falls to the outside from the main guide part 553a through the cutout part 553aa and adheres to the first overhanging part 551da of the top plate part 551a or the second overhanging part 640a of the rear cover 640, the metal powder falls from the first overhanging part 551da of the top plate part 551a or the second overhanging part 640a of the rear cover 640. This prevents game ball B from falling toward the cover body 1501 of the peripheral control unit 1500 attached (to the rear side of the performance display device 1600 attached to the rear surface of the rear box 3010 of the rear unit 3000) and the base body 1502, and thus prevents metal powder of game ball B that has fallen to the outside from the main guiding portion 553a via the cutout portion 553aa from entering the cover body 1501 of the peripheral control unit 1500, thereby preventing electrical problems caused by metal powder of game ball B adhering to the peripheral control board 1510.

[0349] [Comparison between the configuration of measures against metal powder according to the first embodiment and the configuration of measures against metal powder according to the fourth embodiment] In the configuration for preventing metal powder in the first embodiment, the cross-sectional shape in the front-to-rear direction of the top plate portion 551a on which the tank rail 553 is arranged is formed in a stepped shape with multiple downward bends as it moves from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a), as described above, and forms a first eaves portion 551da extended rearward of the pachinko machine 1 so that the lower end of this top plate portion 551a is approximately flush with the rear surface of the tank rail 553.

[0350] In contrast, in the configuration for preventing metal powder according to the fourth embodiment, as shown in Fig. 51, the cross-sectional shape in the front-rear direction of the top plate portion 551a on which the tank rail 553 is arranged is formed in a step-like shape with multiple bends downward from the front edge to the rear edge of the top plate portion 551a (from the front to the rear of the top plate portion 551a), but the rear edge of the bent top plate portion 551a is parallel to the front wall of the gutter-shaped main guide portion 553a formed in the top plate portion 551a, and is formed with a predetermined distance dimension (a distance dimension that is about half the diameter of the game ball B in this embodiment) downward from the bottom of the main guide portion 553a. In other words, the end face of the bent top plate portion 551a is arranged to protrude downward compared to the bottom of the main guide portion 553a.

[0351] In the configuration for preventing metal powder according to the fourth embodiment, the front surface of second overhanging portion 640a formed by bending the upper side of rear cover 640 largely forward when rear cover 640 is assembled to main body frame 4 is arranged parallel to the front wall of gutter-shaped main guide portion 553a and is in surface contact with the rear surface of top plate portion 551a arranged to protrude downward compared to the bottom of main guide portion 553a. The abutting portion between the front surface of second overhanging portion 640a and the rear surface of top plate portion 551a is arranged farther forward than multiple cutout portions 553aa formed in main guide portion 553a.

[0352] Thus, the configuration for preventing metal powder in the first embodiment is different in that the first overhang portion 551da alone forms the overhang portion, whereas the configuration for preventing metal powder in the fourth embodiment is different in that the first overhang portion 551da is not provided and the second overhang portion 640a alone forms the overhang portion.

[0353] The configuration of the metal powder countermeasure according to the fourth embodiment can also achieve the same effect as the configuration of the metal powder countermeasure according to the first embodiment. That is, the metal powder of the game ball B that falls from the main guide portion 553a to the outside through the cutout portions 553aa formed in the main guide portion 553a can be received and adhered to the upper surface of the second eaves portion 640a tha...
