Summary of the Invention

Problems to be Solved by the Invention

[0005] Therefore, in view of the above circumstances, an object of the present invention is to provide a gaming machine capable of reducing the deterioration of the appearance of the game board and suppressing the decrease in the interest of players.

Means for Solving the Problems

[0006] Claim 1 of the present invention is "A gaming machine including a game board having a game area where game balls flow down and provided in the front, wherein the game board is provided to protrude forward from the game board , emitting and includes a launched ball passage portion that guides the launched game balls to the upper part of the game area, and the launched ball passage portion has a backflow prevention valve that prevents the backflow of the game balls. A demolding trace portion is provided at a portion of the backflow prevention valve that does not contact the game balls. , and the backflow prevention valve is composed of a base end portion that is pivotally supported and a single portion that protrudes flatly from the base end portion toward the game ball launch passage portion, and is movable when contacted by a launched game ball. The single portion has a first surface portion that can be contacted by a launched game ball, a second surface portion corresponding to the back side of the first surface portion, a first side surface portion that cannot be contacted by a game ball and faces the front side of the gaming machine, and a second side surface portion that cannot be contacted by a game ball and faces the rear side of the gaming machine. The demolding trace portion in the backflow prevention valve is provided on the second side surface portion of the single portion, and the second side surface portion where the demolding trace portion is provided is configured not to contact the front side of the game board. The gaming machine is characterized by the above. As another invention different from the present invention, the following means are exemplified. Means 1: In a gaming machine, "A gaming machine including a game board having a game plate in which a game area where game balls flow down is provided in the front, The game board, forms a ball passage for guiding the launched game balls to the upper part of the game area, and has a rail member that protrudes forward from the game plate and extends vertically along the ball passage. A demolding trace portion is provided on the rear end surface of the rail member." It is characterized by the above.

[0007] Here, examples of the "rail member" include "the inner rail closer to the center of the game board" and "the outer rail provided outside the inner rail closer to the center of the game board". Further, a backflow prevention valve for preventing the backflow of game balls from the game area to the ball passage may or may not be provided on the rail member.

[0008] In addition, the "demolding trace portion" is a trace left on the rail member by a mechanism (for example, an ejector pin, a push-up core, a straight-up core, a protruding core, etc.) for taking out the rail member from a mold (die), and is slightly recessed, protruding, or inclined compared to other parts. Examples of the shape of this "demolding trace portion" include "a shape of a part of a circle such as a semi-circle", "a circle", "a triangle", "a quadrilateral", "a pentagon", "a hexagon", "a polygon", "an irregular shape", "a star shape", "a heart shape", etc.

[0009] According to the configuration of means 1, there is a gaming machine including a game board having a game board provided with a game area where game balls flow down in the front. The game board forms a ball passage for guiding the launched game balls to the upper part of the game area, and has a rail member that protrudes forward from the game board and extends vertically along the ball passage. A demolding trace portion is provided on the rear end surface of the rail member (in [Mode for Carrying Out the Invention], refer to the chapter of [9-1a. Demolding Trace Portion Provided on the Inner Rail], the description of the previous constituent member 1000, the outer rail 1001, the inner rail 1002, FIGS. 160 to 163, etc.).

[0010] According to this configuration, since the demolding trace portion is provided on the rear end surface of the rail member that guides the game balls to the game area, in the rail member as the part where the player's line of sight goes on the game board, the demolding trace portion can be made less conspicuous from the player's side. Therefore, it is possible to reduce the deterioration of the appearance of the game board due to the visibility of the demolding trace portion, and it is possible to suppress the decrease in the player's interest in the game.

[0011] Also, since the demolding trace portion is provided on the rear end surface of the rail member, the game balls do not come into contact with the demolding trace portion of the rail member, and the demolding trace portion does not affect the movement of the game balls. Therefore, it does not give a sense of strangeness or discomfort to the movement of the game balls flowing through the game area, and it is possible to make the player enjoy the movement of the game balls and suppress the decrease in interest.

[0012] In addition, a backflow prevention valve for preventing the backflow of game balls into the ball passage may be further provided on the game board, and a demolding trace portion may be provided at a portion of the backflow prevention valve that does not come into contact with the game balls. As a result, the backflow prevention valve for preventing the backflow of game balls into the ball passage prevents the game balls in the game area from flowing back into the ball passage, allowing the game balls to flow down surely within the game area and enabling the player to enjoy the game with the game balls. And in this case, in the backflow prevention valve, since the demolding trace portion is provided at a portion that does not come into contact with the game balls, the demolding trace portion of the backflow prevention valve does not affect the movement of the game balls, enabling the player to enjoy the movement of the game balls without discomfort and suppressing a decrease in interest.

[0013] Also, when providing the backflow prevention valve as described above, it is desirable to provide a demolding trace portion at a portion that is difficult for the player to see, such as the rear surface of the backflow prevention valve. This way, the appearance of the backflow prevention valve will not be deteriorated by the demolding trace portion, and the appearance of the game board will not be deteriorated.

[0014] Furthermore, when providing the backflow prevention valve as described above, a holder portion for supporting the backflow prevention valve on the game board so as to be openable and closable may be provided, and a demolding trace portion may be provided at a portion of the holder portion that overlaps with the backflow prevention valve at a predetermined position (closed position or open position). For example, when the backflow prevention valve is in the closed position and the demolding trace portion of the holder portion overlaps with the backflow prevention valve, usually, since the backflow prevention valve is in the closed position, the backflow prevention valve and the demolding trace portion of the holder portion overlap, and the presence of the backflow prevention valve makes the demolding trace portion difficult to see from the player side. On the other hand, when the backflow prevention valve is in the open position, the demolding trace portion of the holder portion and the backflow prevention valve do not overlap, so the demolding trace portion is more visible. However, since the time when the backflow prevention valve is in the open position is only a short time when the game ball passes through the portion of the backflow prevention valve, it is difficult to notice the presence of the demolding trace portion provided in the holder portion. For such reasons, it is difficult for the player to notice the demolding trace portion of the holder portion, so the appearance of the game board will not be deteriorated by the demolding trace portion.

[0015] Also, when providing a holder portion that supports the check valve so as to be openable and closable, in the holder portion, since a demolding trace portion is provided at a portion that overlaps with the check valve at a predetermined position such as a closed position or an open position, when assembling the game board, the check valve is operated to check whether the check valve overlaps with the demolding trace portion of the holder portion, so that the operation of the check valve can be confirmed, and the demolding trace portion of the holder portion can be used as a reference for the operation of the check valve.

[0016] Means 2: In the configuration of Means 1, "The game board further has a check valve for preventing the backflow of game balls into the ball passage, and the demolding trace portion is provided at a portion of the check valve that does not contact the game balls." It is characterized by being such.

[0017] Here, the "check valve" may be provided on the rail member or may be provided separately from the rail member.

[0018] According to the configuration of Means 2, the game board further has a check valve for preventing the backflow of game balls into the ball passage, and a demolding trace portion is provided at a portion of the check valve that does not contact the game balls (refer to the descriptions of the backflow prevention member 1007, the ball backflow prevention unit 1061, FIG. 163, etc. in [Mode for Carrying Out the Invention]).

[0019] According to this configuration, since a check valve for preventing the backflow of game balls into the ball passage is provided, the game balls in the game area do not flow back into the ball passage, and the game balls can be reliably made to flow down in the game area, enabling the player to enjoy the game with the game balls. And in this check valve, since a demolding trace portion is provided at a portion that does not contact the game balls, the demolding trace portion of the check valve does not affect the movement of the game balls, and the player can enjoy the movement of the game balls without discomfort and the decline in interest can be suppressed.

[0020] It is desirable to provide a demolding trace portion at a portion that is difficult for the player to see, such as the rear surface of the backflow prevention valve. This way, the appearance of the backflow prevention valve will not be deteriorated by the demolding trace portion, and the appearance of the game board will not be deteriorated either.

[0021] Means 3: In the configuration of Means 2, "The game board has a holder portion that supports the backflow prevention valve in an openable and closable manner, and the demolding trace portion is provided at a portion that overlaps the backflow prevention valve at a predetermined position on the holder portion." It is characterized by being such.

[0022] Here, as the "holder portion", it may be provided on the rail member or may be provided separately from the rail member.

[0023] According to the configuration of Means 3, the game board has a holder portion that supports the backflow prevention valve in an openable and closable manner, and the demolding trace portion is provided at a portion that overlaps the backflow prevention valve at a predetermined position (closed position or open position) (refer to the descriptions of the backflow prevention member 1007, the backflow prevention unit 1060, FIG. 163, etc. in [Mode for Carrying Out the Invention]).

[0024] According to this configuration, for example, when the backflow prevention valve is in the closed position and the demolding trace portion of the holder portion overlaps the backflow prevention valve, usually, since the backflow prevention valve is in the closed position, the backflow prevention valve and the demolding trace portion of the holder portion overlap, and the presence of the backflow prevention valve makes the demolding trace portion difficult to see from the player side. On the other hand, when the backflow prevention valve is in the open position, the demolding trace portion of the holder portion and the backflow prevention valve do not overlap, so the demolding trace portion is easy to see. However, since the time when the backflow prevention valve is in the open position is only a short time when the game ball passes through the portion of the backflow prevention valve, it is difficult to notice the presence of the demolding trace portion provided on the holder portion. For these reasons, it is difficult for the player to notice the demolding trace portion of the holder portion, so the appearance of the game board is not deteriorated by the demolding trace portion.

[0025] In addition, in the holder portion, since a demolding trace portion is provided at a portion overlapping with the backflow prevention valve at a predetermined position such as a closed position or an open position, when assembling the game board, the backflow prevention valve is operated to check whether the backflow prevention valve overlaps with the demolding trace portion of the holder portion, so that the operation of the backflow prevention valve can be confirmed, and the demolding trace portion of the holder portion can be used as a guide for the operation of the backflow prevention valve.

[0026] Means 4: In the configuration of Means 1 or Means 2, The gaming machine is characterized in that a winning opening through which a game ball can enter the game area is provided, and a pachinko machine that gives a predetermined privilege when the game ball enters the winning opening.

[0027] Here, examples of the "winning opening" include "a general winning opening that is always open in the game area", "a starting winning opening (starting opening) that is always open in the game area and in which a lottery of special symbols is conducted to determine whether a favorable gaming state advantageous to the player is generated as a predetermined privilege when the game ball enters", "a variable winning opening (variable starting opening, accessory winning opening, etc.) in which a game ball can enter the game area as a predetermined privilege when the game ball enters a specific receiving port (chucker) in the game area", "a variable winning opening (variable starting opening, accessory winning opening, etc.) in which a game ball can enter the game area as a predetermined privilege according to the lottery result of ordinary symbols drawn when the game ball passes through a specific area (gate, through chucker, etc.) in the game area", "a variable starting winning opening (variable starting opening) in which a game ball can enter the game area as a predetermined privilege according to the lottery result of ordinary symbols drawn when the game ball passes through a specific area (for example, gate, chucker, etc.) in the game area, and in which a lottery of special symbols is conducted to determine whether a favorable gaming state advantageous to the player is generated as a predetermined privilege when the game ball enters", "a V winning opening in which when the game ball that has entered the accessory winning opening is distributed and enters by the distribution means, a favorable gaming state advantageous to the player is generated as a predetermined privilege", "a large winning opening or an accessory winning opening that opens and closes in a predetermined pattern and allows the game ball to enter as a favorable gaming state advantageous to the player as a predetermined privilege", and the like.

[0028] In addition, as a "pachinko machine", there is "a lottery means for conducting a special symbol lottery for generating an advantageous gaming state in which a player is advantaged as a predetermined privilege by the entry of a gaming ball into the start port, and a special symbol is variably displayed according to the lottery result of the special symbol lottery by the lottery means and then stopped and displayed, and a special lottery result display means as a display for displaying a special lottery result selected by the combination of the stopped and displayed special symbols. When a special lottery result that generates an advantageous gaming state is displayed by the special lottery result display means, an advantageous gaming state generation means for opening and closing the big winning port in a predetermined pattern to generate an advantageous gaming state", (so-called, digital pachinko machine), "a distribution means for distributing the gaming balls that have entered the accessory winning port, and an advantageous gaming state generation means for opening and closing the accessory winning port in a predetermined pattern as a predetermined privilege when the gaming balls distributed by the distribution means enter the V winning port to generate an advantageous gaming state in which the player is advantaged", (so-called, wing machine), "a machine having a big winning port and an accessory winning port, opening and closing the big winning port or the accessory winning port in a predetermined pattern according to the lottery result of the special symbol lottery selected by the entry of the gaming ball into the start port (start entry), and when the gaming balls that have entered the accessory winning port are distributed to the V winning port, opening and closing the accessory winning port or the big winning port in a predetermined pattern as a predetermined privilege to generate an advantageous gaming state generation means for generating an advantageous gaming state in which the player is advantaged", (so-called, composite machine), etc. can be mentioned.

[0029] According to the configuration of means 4, the gaming machine is a pachinko machine provided with a winning port into which a gaming ball can enter the gaming area, and a predetermined privilege is given by the entry of the gaming ball into the winning port. Thereby, in the pachinko machine, the action effects of any of the above-described means can be achieved.

The lower right connecting member 23 includes a horizontally extending flat plate-shaped horizontal fixing portion 23a, a flat plate-shaped upper horizontal fixing portion 23b that extends upward from the right side of the horizontal fixing portion 23a and extends rearward from the horizontal fixing portion 23a, a flat plate-shaped lower horizontal fixing portion 23c that extends downward from a portion on the lower side of the upper horizontal fixing portion 23b and rearward from the horizontal fixing portion 23a, and a flat plate-shaped abutting portion 23d that extends short leftward from the rear side of the upper horizontal fixing portion 23b. The lower right connecting member 23 is formed by bending a flat plate-shaped metal plate.

[0063] The lower right connecting member 23 has the rear surface of the abutting portion 23d abutted against the front surface of the bulging portion 21b of the outer frame right member 21, with the right side surface of the upper horizontal fixing portion 23b abutted against the left side surface of the outer frame right member 21, and with the lower surface of the horizontal fixing portion 23a aligned with the lower end of the outer frame right member 21. Then, screws are screwed into the upper horizontal fixing portion 23b from the outside of the right side surface of the outer frame right member 21, thereby being attached to the outer frame right member 21. Also, the lower right connecting member 23 has its horizontal fixing portion 23a abutted against the upper surface of the right end side of the outer frame lower member 41, with its lower horizontal fixing portion 23c inserted into the notch portion 41a of the right side surface of the outer frame lower member 41. Then, screws are screwed into the outer frame lower member 41 through the horizontal fixing portion 23a and the lower horizontal fixing portion 23c, thereby being attached to the outer frame lower member 41.

[0064] The upper hook member 24 and the lower hook member 25 are for the outer frame hook 653 of the locking unit 650 in the main body frame 4 described later to be hooked thereon. The upper hook member 24 has a flat mounting portion 24a that extends vertically with a constant width in the front-rear direction and is attached to the left side surface of the outer frame right member 21, and a flat hook portion 24b that extends leftward from the front edge of the mounting portion 24a and on which the upper outer frame hook 653 is hooked.

[0065] The lower hook member 25 has a flat mounting portion 25a that extends vertically with a constant width in the front-rear direction and is attached to the left side surface of the outer frame right member 21, a flat hook portion 25b that extends leftward from the front edge of the mounting portion 25a and on which the lower outer frame hook 653 is hooked, and a through hole 25c that penetrates the hook portion 25b in the front-rear direction and through which the lower outer frame hook 653 can be inserted.

[0066] [2-2. Upper member of outer frame] Regarding the upper member 30 of the outer frame 2 of the outer frame, it will be described in detail mainly with reference to FIG. 16. The upper member 30 of the outer frame is for connecting the upper ends of the outer frame left assembly 10 and the outer frame right assembly 20 that are spaced apart from each other left and right. The upper member 30 of the outer frame has a width in the front-rear direction that is substantially the same as the front-rear direction of the outer frame left member 11 and the outer frame right member 21, a constant thickness in the vertical direction, and extends in the left-right direction, and is formed of wood. The length of the upper member 30 of the outer frame in the left-right direction is formed to be the same as the length in the left-right direction of the outer frame lower member 41 of the outer frame lower assembly 40 described later.

[0067] The upper member 30 of the outer frame has cutouts 30a that are recessed toward the center in the left-right direction in a state of penetrating vertically at the center in the front-rear direction on both the left and right side surfaces. The upper horizontal fixing portions 12b of the upper left connecting member 12 and the upper horizontal fixing portions 22b of the upper right connecting member 22 are respectively attached to the cutouts 30a at both the left and right ends in a state of being inserted therein.

[0068] Also, the upper member 30 of the outer frame has a mounting step portion 30b at the left end portion where the upper surface and the front surface are recessed more than the general surface. The outer frame upper hinge assembly 50 described later is attached to this mounting step portion 30b.

[0069] [[2-3. Lower Outer Frame Assembly]] The lower outer frame assembly 40 of the outer frame 2 will be described in detail mainly with reference to FIG. 18. FIG. 18 is an exploded perspective view of the lower outer frame assembly of the outer frame as seen from the front with the components disassembled. The lower outer frame assembly 40 connects the lower ends of the left and right outer frame assemblies 10 and 20 which are spaced apart from each other left and right, and is for closing and decorating the area below the door frame 3 in the pachinko machine 1.

[0070] The lower outer frame assembly 40 includes an outer frame lower member 41 that connects the lower ends of the left and right outer frame assemblies 10 and 20 which are spaced apart from each other left and right and extends left and right, a box-shaped front curtain member 42 that is disposed in front of the outer frame lower member 41, extends left and right along the outer frame lower member 41, and has an open rear, and a box-shaped rear curtain member 43 that is attached to the rear side of the front curtain member 42, is attached to the upper surface of the outer frame lower member 41, extends left and right with an open front, and a ball biting prevention mechanism 44 formed at the left end on the upper surface of the rear curtain member 43.

[0071] The outer frame lower member 41 has a width in the front-rear direction that is substantially the same as the front-rear direction of the left and right outer frame members 11 and 21, a constant thickness in the vertical direction, extends in the left-right direction, and is formed of wood. The outer frame lower member 41 is formed to have the same length in the left-right direction as the left-right length of the outer frame upper member 30.

[0072] The outer frame lower member 41 is provided with cutouts 41a that penetrate vertically and are recessed toward the center in the left-right direction at the center in the front-rear direction on both the left and right side surfaces. The lower horizontal fixing portions 13c of the left lower connecting member 13 and the lower horizontal fixing portions 23c of the right lower connecting member 23 are respectively attached in a state of being inserted into the cutouts 41a at both the left and right ends. Thereby, the lower ends of the left and right outer frame members 11 and 21 can be connected.

[0073] Further, the lower outer frame member 41 is recessed from the upper surface and has a recess 41b into which the lower part of the curtain plate rear member 43 is inserted. The recess 41b extends horizontally and opens from a position near the rear of the center in the front-rear direction toward the front end side. This recess 41b maximally expands the volume of the curtain plate internal space 40a formed by the curtain plate front member 42 and the curtain plate rear member 43.

[0074] The curtain plate front member 42 extends in the left-right direction with the same length as the lower outer frame member 41, and is formed in a horizontally long rectangular parallelepiped box shape with a short depth in the front-rear direction relative to the height, and the entire rear surface is open. The curtain plate front member 42 closes the open rear side with the curtain plate rear member 43, and cooperates with the curtain plate rear member 43 to form a curtain plate internal space 40a that is part of the enclosure 624 of the main body frame speaker 622. The curtain plate front member 42 is provided with an elongated hole-shaped opening 42a that penetrates in the front-rear direction and extends in the left-right direction on the front surface near the right end.

[0075] The curtain plate rear member 43 extends in the left-right direction slightly shorter than the lower outer frame member 41 and is formed in a box shape with an open front. The curtain plate rear member 43 attaches the curtain plate front member 42 to the front surface, and cooperates with the curtain plate front member 42 to form a curtain plate internal space 40a that is part of the enclosure 624 of the main body frame speaker 622. The curtain plate rear member 43 has a cylindrical connection tube portion 43a that extends in the left-right direction, protrudes upward, and communicates with the curtain plate internal space 40a at the center in the left-right direction on the upper surface. The upper end of the connection tube portion 43a is inclined so that it is positioned upward from the front end side where it coincides with the general upper surface of the curtain plate rear member 43 toward the rear. In this embodiment, the upper end of the connection tube portion 43a is inclined at an angle of 45 degrees.

[0076] This connecting cylinder portion 43a is formed such that its length in the left - right direction is about 1 / 3 of the length of the entire rear curtain member 43, and its depth in the front - rear direction is formed slightly shorter than the depth of the entire rear curtain member 43. Inside the connecting cylinder portion 43a, a plurality of ribs 43b connecting the front - end side and the rear - end side are provided. At the upper end of this connecting cylinder portion 43a, when the main body frame 4 is closed with respect to the outer frame 2, the connecting portion 621c of the speaker cover 621 in the speaker unit 620a of the substrate unit 620 in the main body frame 4 is connected, and it is in a state of communicating with the internal space of the speaker unit 620a, forming an enclosure 624.

[0077] The ball - biting prevention mechanism 44 is for preventing the game ball B from being pinched between the outer frame 2 and the main body frame 4 when the game ball B stays at the position of the lower outer - frame hinge member 60 at the left end on the upper surface of the rear curtain member 43.

[0078] The ball - biting prevention mechanism 44 is formed at the left end on the upper surface of the rear curtain member 43, and includes a placement portion 44a formed flat so that the lower outer - frame hinge member 60 described later is placed thereon, a first discharge port 44b that opens upward at the left end of the placement portion 44a, a second discharge port 44c that opens upward and is to the right of the first discharge port 44b in the placement portion 44a, a standing wall portion 44d that extends upward from the rear side and the right side of the placement portion 44a, and an upper - end protruding portion 44e that protrudes forward from the upper end of the standing wall portion 44d and whose upper surface is inclined so as to be positioned upward as it goes rearward.

[0079] The first discharge port 44b is formed at a position that coincides with the discharge hole 60d of the lower outer - frame hinge member 60 described later. The first discharge port 44b and the second discharge port 44c are formed to have a size through which the game ball B can pass. The first discharge port 44b and the second discharge port 44c are not in communication with the internal space 40a of the curtain, but open to the rear surface of the rear curtain member 43. Therefore, the game ball B that has entered the first discharge port 44b and the second discharge port 44c can be discharged to the rear of the rear curtain member 43.

[0080] This ball jamming prevention mechanism 44 can prevent an unauthorized tool such as a piano wire from being inserted through the gap between the outer frame lower hinge member 60 and the main body frame lower hinge assembly 520 described later. When an unauthorized tool is inserted, the vertical wall portion 44d rising from the rear end of the placement portion 44a can block the intrusion of the unauthorized tool. Even if the tip of the unauthorized tool contacts the vertical wall portion 44d and bends upward, it will contact the upper end protruding portion 44e protruding forward provided at the upper end of the vertical wall portion 44d, preventing further intrusion. Therefore, unauthorized acts can be prevented through the portion of the outer frame lower hinge member 60.

[0081] By the way, when the vertical wall portion 44d is provided at the rear end of the placement portion 44a, when the main body frame 4 is opened with respect to the outer frame 2, the game ball B that has fallen onto the placement portion 44a for some reason is blocked from moving backward by the vertical wall portion 44d, so the game ball B tends to stay on the placement portion 44a. And when the game ball B stays on the placement portion 44a, when the main body frame 4 is closed with respect to the outer frame 2, the game ball B will be sandwiched between the outer frame 2 and the main body frame 4, causing a problem that the main body frame 4 cannot be closed.

[0082] In contrast, in the ball jamming prevention mechanism 44 of this embodiment, the game ball B that has fallen onto the outer frame lower hinge member 60 or the placement portion 44a can be discharged to the rear of the curtain plate rear member 43 (behind the outer frame 2) through the discharge hole 60d of the outer frame lower hinge member 60 and the first discharge port 44b, or through the second discharge port 44c, preventing the game ball B from being sandwiched between the outer frame 2 and the main body frame 4.

[0083] The outer frame lower assembly 40 includes a pair of guide members 45 spaced apart left and right on the upper surfaces of the curtain plate front member 42 and the curtain plate rear member 43, a flat grill member 46 that closes the opening 42a of the curtain plate front member 42 from the rear side, a port member 47 having two cylinders extending in the front-rear direction and attached inside the curtain plate front member 42 so as to close the opening 42a with the grill member 46 sandwiched therebetween, and a frame-shaped seal member 48 disposed at the upper end of the connection cylinder portion 43a of the curtain plate rear member 43.

[0084] The pair of guide members 45 are such that when the main body frame 4 is closed with respect to the outer frame 2, the lower end of the door frame 3 abuts thereon. The guide members 45 are formed of a low-friction material with low frictional resistance, facilitating the sliding of the lower end of the main body frame 4 and making the opening and closing easier.

[0085] The grill member 46 is in the shape of a strip extending in the left-right direction and has a plurality of blade portions 46b provided at intervals in the vertical direction. The blade portions 46b are provided in an inclined state such that the front end side is higher than the rear end side. This grill member 46 allows the interior (the curtain plate internal space 40a) and the exterior of the front curtain plate member 42 to communicate with each other through the gaps between the blade portions 46b.

[0086] The port member 47 connects the curtain plate internal space 40a (enclosure 624) and the front of the outer frame 2 through the gaps between the blade portions 46b of the grill member 46 by means of two cylinders. The two cylinders of the port member 47 are formed with a predetermined inner diameter and a predetermined length, and resonate and amplify the bass sound emitted from the main body frame speaker 622 to the rear (inside the enclosure 624) according to the principle of Helmholtz resonance, enabling rich bass to be radiated to the front of the outer frame 2 (towards the player). That is, in this embodiment, the enclosure 624 of the main body frame speaker 622 is of the bass reflex type, allowing the player to hear heavy bass.

[0087] The seal member 48 is compressed and sandwiched between the upper end of the connection cylinder portion 43a and the lower end of the connection portion 621c of the speaker cover 621 in the main body frame 4 when the main body frame 4 is closed with respect to the outer frame 2, preventing the sound inside the enclosure 624 of the main body frame speaker 622 from leaking from between the connection cylinder portion 43a and the connection portion 621c.

[0088] According to the grill member 46 of the present embodiment, the air vibration discharged from the inner space 40a of the curtain plate to the outside by the main body frame speaker 622 is inclined by a plurality of blade portions 46b, and passes through the notch opening 295b below the handle cover 295 in the handle cover unit 290 obliquely forward. It can be directed into the front cylinder portion 291a of the handle cover base 291 in which the handle unit 180 is accommodated. As a result, when the player inserts a finger inside the handle cover 295 (the front cylinder portion 291a of the handle cover base 291) and rotates the handle 197 (the device for driving the game ball B), the main body frame speaker 622 is vibrated to send wind into the front cylinder portion 291a, so that the player can be surprised and a novel effect can be produced.

[0089] Further, since the port member 47 is opened forward, a part of the sound pressure discharged from the port member 47 through the plurality of blade portions 46b of the grill member 46 is discharged forward. Therefore, for a player sitting in front of the pachinko machine 1 or another player wandering in the game hall where the pachinko machine 1 is installed, the effect sound discharged from the port member 47 can be heard, and the player's interest can also be attracted by the effect sound, and a pachinko machine 1 with high appeal to the player can be provided.

[0090] In addition, since the port member 47 is provided on the outer frame lower assembly 40 of the outer frame 2 with respect to the enclosure 624 of the main body frame speaker 622 provided on the main body frame 4, the volume of the enclosure 624 can be increased, so that a more bassy effect sound can be output, and the player can be entertained and the decline in interest can be suppressed.

[0091] [2-4. Outer frame upper hinge assembly] The upper frame hinge assembly 50 of the outer frame 2 will be described in detail mainly with reference to FIG. 19. FIG. 19(a) is an exploded perspective view of the upper frame hinge assembly of the outer frame as seen from the front upper side after disassembly, and (b) is an exploded perspective view of (a) as seen from the front lower side. The upper frame hinge assembly 50 is attached to the upper end of the left outer frame assembly 10 and the left end of the upper frame member 30, and is for pivotally attaching the main body frame 4 to the outer frame 2. The upper frame hinge assembly 50 includes an upper frame hinge member 51 attached to the upper end of the recess 11a of the left outer frame member 11 and the mounting step portion 30b of the upper frame member 30, a lock member 52 attached to the upper frame hinge member 51, and a mounting screw 53 attaching the lock member 52 to the upper frame hinge member 51.

[0092] The upper frame hinge member 51 has a flat plate shape extending horizontally and is attached to the upper surface of the mounting step portion 30b of the upper frame member 30, a flat plate-shaped front extension portion 51b extending forward from the front side of the upper fixing portion 51a, a bearing groove 51c extending from the middle of the right side of the front extension portion 51b toward the left and right center of the front extension portion 51b and penetrating vertically, a flat plate-shaped lateral fixing portion 51d extending downward from the left side of the upper fixing portion 51a, and a flat plate-shaped edge wall portion 51e extending downward from the edge of the front extension portion 51b from the left side around the front side to the part where the bearing groove 51c opens and continuous with the lateral fixing portion 51d. The upper frame hinge member 51 is formed by punching and bending a metal plate by press molding. The upper frame hinge member 51 can rotatably support a main body frame upper hinge pin 512 (to be described later) of the main body frame upper hinge member 510 in the bearing groove 51c.

[0093] The lock member 52 includes a strip-shaped lock body 52a extending in the front-rear direction, an operation piece 52b protruding rightward from the rear end of the lock body 52a, an elastically deformable rod-shaped elastic portion 52c extending leftward from the rear end of the lock body 52a and then obliquely forward-leftward, and a mounting hole 52d penetrating vertically near the rear end of the lock body 52a. The lock member 52 is formed of synthetic resin. The lock member 52 is rotatably mounted by a mounting screw 53 on the lower surface of the front extending portion 51b of the outer frame upper hinge member 51 at a position behind the bearing groove 51c.

[0094] In the state where the lock member 52 is attached to the outer frame upper hinge member 51, the lock body 52a can block the bearing groove 51c in plan view, and the right side surface near the front end extends forward so as to be able to contact a portion extending to the opening of the bearing groove 51c in the edge wall portion 51e of the outer frame upper hinge member 51. Further, the tip of the elastic portion 52c extending leftward from the rear end of the lock body 52a is in contact with the inner peripheral surface of the edge wall portion 51e of the outer frame upper hinge member 51. This lock member 52 is biased in the direction in which the front end rotates leftward about the mounting hole 52d by the biasing force of the elastic portion 52c. Therefore, in the normal state, the right side surface near the front end of the lock body 52a of the lock member 52 is in contact with the edge wall portion 51e. In this state, a space capable of accommodating the main body frame upper hinge pin 512 of the main body frame upper hinge member 510 is formed in the portion of the bearing groove 51c in front of the lock body 52a.

[0095] By operating the operation piece 52b, this lock member 52 can rotate the lock body 52a against the biasing force of the elastic portion 52c. Then, by operating the operation piece 52b to rotate the lock body 52a in the direction in which the front end moves leftward, the lock body 52a can be retracted from the bearing groove 51c in plan view, and the bearing groove 51c can be made to be fully open. Thereby, the main body frame upper hinge pin 512 can be inserted into the bearing groove 51c or removed from the bearing groove 51c.

[0096] [2-5. Lower hinge member of the outer frame] The lower hinge member 60 of the outer frame 2 of the outer frame will be described in detail mainly with reference to FIG. 16. The lower hinge member 60 of the outer frame includes a horizontally extending flat plate-shaped horizontal portion 60a, a flat plate-shaped upright portion 60b that rises upward from a portion on the left side of the horizontal portion 60a that is behind the center in the front-rear direction, an outer frame lower hinge pin 60c that protrudes upward near the front end of the horizontal portion 60a, and a discharge hole 60d that penetrates the horizontal portion 60a vertically and has a size that allows only one game ball B to pass through. This lower hinge member 60 of the outer frame is formed by punching and bending a metal plate by press molding.

[0097] The horizontal portion 60a of the lower hinge member 60 of the outer frame is formed in a trapezoid shape with the left side as the bottom side in plan view. The outer frame lower hinge pin 60c is columnar, and the upper part above the center in the vertical direction is formed in a frustum of a cone shape with the upper end narrowed. This outer frame lower hinge pin 60c is attached to a position on the left side near the front end of the horizontal portion 60a. The discharge hole 60d is formed in the horizontal portion 60a so as to be in contact with the central portion in the front-rear direction of the upright portion 60b and extend in an inverted U shape from the left side to the right side of the horizontal portion 60a. This discharge hole 60d is formed to have substantially the same size as the first discharge port 44b of the ball biting prevention mechanism 44 in the outer frame lower assembly 40.

[0098] In a state where the lower hinge member 60 of the outer frame is assembled to the outer frame 2, the rear part of the horizontal portion 60a is placed on the placement portion 44a of the curtain plate rear member 43 in the outer frame lower assembly 40 and fixed to the curtain plate rear member 43 with screws (not shown). Also, the upright portion 60b is attached to a portion in front of the bulging portion 11b on the right side surface of the outer frame left member 11 with screws (not shown). This lower hinge member 60 of the outer frame can be attached to the main body frame 4 so as to be openable and closable in cooperation with the upper hinge member 51 of the outer frame by inserting the outer frame lower hinge pin 60c into the outer frame lower hinge hole 521a in the main body frame lower hinge assembly 520 of the main body frame 4.

[0099] Also, in the state where the outer frame 2 is assembled, the discharge hole 60d coincides with the first discharge port 44b of the ball biting prevention mechanism 44 in the lower outer frame assembly 40. Thereby, the game ball B on the horizontal portion 60a can be dropped (discharged) backward of the outer frame 2 through the discharge hole 60d and the first discharge port 44b. More specifically, when closing the main body frame 4 with respect to the outer frame 2, as the main body frame 4 is closed, the game ball B that has fallen between the outer frame 2 and the main body frame 4 gradually narrows the space between the outer frame 2 and the main body frame 4, so it will roll to the rear side with a wider interval and can be discharged from the discharge hole 60d. At this time, since the discharge hole 60d is formed at a position substantially the same as the rear end of the main body frame 4 when the main body frame 4 is closed with respect to the outer frame 2 in the state where the pachinko machine 1 is assembled, it is easier to prevent the game ball B that has fallen between the outer frame 2 and the main body frame 4 from rolling to the rear side by discharging it from the discharge hole 60d, and it is possible to make it difficult for the game ball B to stay at the portion of the lower outer hinge member 60 of the outer frame.

[0100] [3. Overall Structure of the Door Frame] The door frame 3 of the pachinko machine 1 will be described in detail mainly with reference to FIGS. 20 to 33 and the like.

FIG. 33 is a longitudinal sectional view of the door frame in a state where the upper door frame decoration body is removed.

[0101] The door frame 3 is formed in a rectangular shape that is approximately the same size as the inside of the outer frame 2 and extends vertically in a front view, and is attached to the inside of the outer frame 2 via the main body frame 4 so as to be openable and closable from the front side. The door frame 3 closes the game area 5a of the game board 5 into which the pachinko balls B are driven so that it can be visually recognized from the front side, stores the pachinko balls B for driving into the game area 5a, and includes a handle 197 that is operated by the player to drive the stored pachinko balls B into the game area 5a.

[0127] The handle rear relay board has a rectangular outer shape extending left and right, and is attached to the rear side of the handle mounting seat surface below the ball feeding opening 101e on the rear side of the door frame base 101. The handle rear relay board relays the connection between the door frame main relay board 104 and the handle rotation detection sensor 189, the handle touch sensor 192, the single-shot button operation sensor 194 of the handle unit 180, and the ball feeding solenoid 145 of the ball feeding unit 140. In the state where the door frame base unit 100 is assembled, the rear side of the handle rear relay board is covered by the handle rear relay board cover 108.

[0128] [3-1d. Door Frame Relay Board Cover · Handle Rear Relay Board Cover · Cable Cover] The door frame relay board cover 107, the handle rear relay board cover 108, and the cable cover 109 of the door frame base unit 100 will be mainly described with reference to FIG. 25.

[0130] [3-1e. Door Frame Reinforcement Unit] The door frame reinforcement unit 110 of the door frame base unit 100 will be described in detail mainly with reference to FIGS. 35 to 38. FIG. 35(a) is a perspective view of the door frame reinforcement unit in the door frame seen from the front, and (b) is a perspective view of the door frame reinforcement unit in the door frame seen from the rear. FIG. 36(a) is a perspective view of the intermediate reinforcement frame of the door frame reinforcement unit seen from the front, and (b) is a perspective view of the intermediate reinforcement frame of the door frame reinforcement unit seen from the rear. FIG. 37 is an explanatory view showing an enlarged part of the intermediate reinforcement frame in the longitudinal section of the door frame. FIG. 38 is an explanatory view showing the dimensional relationship of the upper part of the intermediate reinforcement frame.

[0131] The door frame reinforcement unit 110 is attached to the rear side of the door frame base 101 to reinforce the flat door frame base 101 made of synthetic resin and impart rigidity to the door frame base unit 100. The door frame reinforcement unit 110 includes left and right spaced-apart vertically extending left reinforcement frame 111 and right reinforcement frame 112, a horizontally extending upper reinforcement frame 113 connecting the upper ends of the left reinforcement frame 111 and the right reinforcement frame 112, an intermediate reinforcement frame 117 connecting the upper-ward parts of the lower ends of the left reinforcement frame 111 and the right reinforcement frame 112, a cylinder mounting frame 115 attached to the right reinforcement frame 112 (see FIG. 34, etc.), and a hook member 116 to which the door frame hook 652 of the locking unit 650 of the main body frame 4 is hooked and which is attached to the rear side of the right reinforcement frame 112 at a plurality of vertically spaced positions.

[0132] The left reinforcing frame 111 extends vertically with a substantially constant width and a length substantially the same as the height of the door frame base 101, and has a bulging portion 111a that protrudes rightward at a position above the lower end. The left end side of the intermediate reinforcing frame 117 is attached to the bulging portion 111a of the left reinforcing frame 111.

[0133] The right reinforcing frame 112 extends vertically with a substantially constant width and a length substantially the same as the height of the door frame base 101, and has a bulging portion 112a that protrudes leftward at a position above the lower end. The right end side of the intermediate reinforcing frame 117 is attached to the bulging portion 112a of the right reinforcing frame 112. Further, a cylinder mounting frame 115 is attached to the front surface of the bulging portion 112a. A plurality of insertion holes that are spaced apart in the vertical direction and penetrate in the front-rear direction are formed in the right reinforcing frame 112. When the door frame 3 is closed with respect to the main body frame 4, the tip of the door frame hook 652 of the locking unit 650 is inserted through these insertion holes.

[0134] The upper reinforcing frame 113 extends horizontally with a constant width in the vertical direction and a length substantially the same as the left-right width of the door frame base 101.

[0135] The door frame reinforcing unit 110 is attached to the rear side of the door frame base 101 by a plurality of screws (not shown). In a state where the door frame reinforcing unit 110 is attached to the door frame base 101, the through portion 117f of the intermediate reinforcing frame 117 coincides with the through hole of the door frame base 101, and the cylinder mounting frame 115 is inserted into the cylinder insertion hole 101d of the door frame base 101.

[0136] [3-1e-1. Intermediate Reinforcing Frame] Next, the intermediate reinforcement frame 117 in the door frame reinforcement unit 110 will be described in detail. As shown in FIG. 36, the intermediate reinforcement frame 117 is attached so as to connect the bulging portion 111a of the left reinforcement frame 111 and the bulging portion 112a of the right reinforcement frame 112. The intermediate reinforcement frame 117 extends horizontally with a width in the vertical direction wider than the vertical width of the upper reinforcement frame 113. The lower end side of the intermediate reinforcement frame 117 is linear and extends horizontally, while the left and right ends of the upper end side are higher as they extend outward in the horizontal direction. The intermediate reinforcement frame 117 has a through portion 117f that penetrates in the front-rear direction near the right end, and an opening 117g that penetrates in a square shape in the front-rear direction near the left end. The through portion 117f is formed at a position that coincides with the through hole of the door frame base 101. The opening 117g is formed so as to coincide with the upper dish ball passage port 101g of the door frame base 101.

[0137] The intermediate reinforcement frame 117 has a strip-shaped substrate portion 117a with its plate surface facing in the front-rear direction, an upper flange portion 117b extending rearward from the upper edge of the substrate portion 117a, a rear flange portion 117c extending upward from the rear edge of the upper flange portion 117b, and a lower flange portion 117d extending forward from the lower edge of the substrate portion 117a.

[0138] Further, the intermediate reinforcement frame 117 is provided with a plurality of bead portions 117e that protrude forward and are long in the left-right direction on the substrate portion 117a. The strength and rigidity of the substrate portion 117a (intermediate reinforcement frame 117) are enhanced by these plurality of bead portions 117e.

[0139] As shown in Fig. 36(b), the intermediate reinforcing frame 117 is composed of a first sheet metal part 118a having the same thickness as the sheet metal forming the left reinforcing frame 111 and the right reinforcing frame 112, and a second sheet metal part 118b having a greater thickness than the first sheet metal part 118a. The first sheet metal part 118a has a substrate part 117a, an upper flange part 117b, and a lower flange part 117d. The second sheet metal part 118b has a substrate part 117a, an upper flange part 117b, and a rear flange part 117c. The upper flange part 117b, the rear flange part 117c, and the lower flange part 117d are formed by bending the sheet metal. The first sheet metal part 118a and the second sheet metal part 118b are attached to each other at the site of their respective substrate parts 117a with a plurality of rivets, with the first sheet metal part 118a facing forward.

[0140] The length of the first sheet metal part 118a in the left-right direction is the same as the length of the intermediate reinforcing frame 117 in the left-right direction. The length of the second sheet metal part 118b in the left-right direction is shorter than that of the first sheet metal part 118a. The second sheet metal part 118b is attached so as to cover the central part of the first sheet metal part 118a in the left-right direction. Note that the thickness tc of the second sheet metal part 118b is approximately 1.7 times the thickness of the first sheet metal part 118a.

[0141] In the state where this intermediate reinforcing frame 117 is assembled to the door frame 3, it is located below the door window 101a and behind the dish unit 200 (the production operation unit 300 to be described later) (see Figs. 33 and 37). Also, as shown in the figure, the lower end of the glass frame 161 (locking piece 161b) in 160 abuts on the upper surface of the upper flange part 117b of the intermediate reinforcing frame 117. That is, the glass unit 160 is placed on the upper flange part 117b. Further, the lower rear surface (the rear surface of the locking piece 161b) of the glass frame 161 in the glass unit 160 abuts on the front surface of the rear flange part 117c of the intermediate reinforcing frame 117. Thereby, the intermediate reinforcing frame 117 restricts the downward movement and the rearward movement of the lower part of the glass unit 160. Note that in the present embodiment, the rear surface of the rear flange part 117c is located in front of the rear surface of the glass unit 160 and does not protrude rearward.

[0142] In the intermediate reinforcement frame 117 of this embodiment, the upper and lower widths at both ends in the left - right direction are larger than the upper and lower widths at the center in the left - right direction, and since the portions with large upper and lower widths are attached to the left reinforcement frame 111 and the right reinforcement frame 112, it is attached more firmly than the intermediate reinforcement frame in a conventional door frame.

[0143] Further, the intermediate reinforcement frame 117 has an upper flange portion 117b, a rear flange portion 117c, and a lower flange portion 117d, and is formed in a cross - sectional shape like a combination of two crank shapes. Also, the intermediate reinforcement frame 117 is composed of two sheet metals, a first sheet metal portion 118a and a second sheet metal portion 118b. For this reason, the intermediate reinforcement frame 117 has higher strength and rigidity than the intermediate reinforcement frame 114 of the door frame 3 in the first embodiment. Therefore, the door frame reinforcement unit 110 itself also has higher strength and rigidity than the door frame reinforcement unit of a conventional door frame.

[0144] In this way, since the strength and rigidity of the intermediate reinforcement frame 117 (door frame reinforcement unit 110) are enhanced, even if a player grabs and strongly pulls the upper plate 201 or the lower plate 202, or strongly pulls the lever operation portion 304 of the effect operation unit 300 described later, the intermediate reinforcement frame 117 (door frame reinforcement unit 110) will not be distorted (plastically deformed). Therefore, it is possible to prevent a gap from being formed between the door frame 3 and the main body frame 4 due to the distortion of the intermediate reinforcement frame 117.

[0145] Also, even if an attempt is made to form a gap between the door frame 3 and the main body frame 4 by strongly pulling the upper plate 201 or the lever operation portion 304 forward to perform an illegal act, as described above, the intermediate reinforcement frame 117 (door frame reinforcement unit 110) with enhanced strength and rigidity prevents the door frame 3 from being plastically deformed and forming a gap with the main body frame 4, and it is possible to provide a pachinko machine 1 with a high deterrent force against illegal acts.

[0146] In addition, the intermediate reinforcing frame 117 has an upper flange portion 117b on which the glass unit 160 is placed and a rear flange portion 117c extending upward from the upper flange portion 117b. Therefore, not only can the load of the glass unit 160 be supported, but even if an unauthorized tool tries to intrude through the space between the upper flange portion 117b and the lower end of the glass unit 160, the intrusion of the unauthorized tool can be blocked by the rear flange portion 117c extending upward, and a pachinko machine 1 with a high deterrent force against unauthorized acts can be provided.

[0147] Note that, as shown in FIG. 38, the intermediate reinforcing frame 117 is configured such that the distance L1 from the rear surface of the substrate portion 117a to the rear end of the upper flange portion 117b is slightly shorter than the distance L2 from the upper surface of the upper flange portion 117b to the upper end of the rear flange portion 117c. Also, the distance L0 obtained by adding the distance L1 and the distance L2 is configured to be longer than the distance (not shown) from the rear surface of the substrate portion 117a to the rear end of the door frame 3. Therefore, if the rear flange portion 117c is extended rearward in the same manner as the upper flange portion 117b without being bent upward, its rear end is configured to protrude rearward beyond the rear end of the door frame 3. That is, the length at which the rear end can enter the rear game board 5 is set according to the angle at which the rear flange portion 117c is extended (bent) with respect to the upper flange portion 117b.

[0148] [3-1e-2. Modification Examples of Intermediate Reinforcing Frame] Subsequently, modification examples (modification examples 1 to 5) of the intermediate reinforcing frame 117 will be described in detail with reference to FIGS. 39 and 40. FIG. 39(a) is an explanatory diagram showing modification example 1 of the intermediate reinforcing frame in the door frame, (b) is an explanatory diagram showing modification example 2 of the intermediate reinforcing frame, and (c) is an explanatory diagram showing modification example 3 of the intermediate reinforcing frame. FIG. 40(a) is an explanatory diagram showing modification example 4 of the intermediate reinforcing frame in the door frame, and (b) is an explanatory diagram showing modification example 5 of the intermediate reinforcing frame. Here, parts having the same configuration as the intermediate reinforcing frame 117 will be described with the same reference numerals.

[0149] (Modification Example 1 of Intermediate Reinforcing Frame) The intermediate reinforcement frame 117A shown in Fig. 39(a) is composed of a single thick metal plate (sheet metal). The intermediate reinforcement frame 117A also has the same effects as described above. Further, according to this intermediate reinforcement frame 117A, since it is composed of a single sheet metal, there is no need to assemble with rivets or the like as compared with the case of being composed of a plurality of sheet metals, and the cost can be reduced. Note that a bead portion 117e may also be provided on this intermediate reinforcement frame 117A.

[0150] (Modification Example 2 of Intermediate Reinforcement Frame) The intermediate reinforcement frame 117B shown in Fig. 39(b) is such that the lower flange portion 117d extends rearward from the lower end of the substrate portion 117a. The strength and rigidity of the intermediate reinforcement frame 117B can also be enhanced by the lower flange portion 117d extending rearward, and the same effects as described above are achieved. Note that the intermediate reinforcement frame 117B may be composed of a single sheet metal as shown in the figure, or may be composed of a plurality of sheet metals in the same manner as the above intermediate reinforcement frame 117. Also, a bead portion 117e may be provided on the intermediate reinforcement frame 117B.

[0151] (Modification Example 3 of Intermediate Reinforcement Frame) In the intermediate reinforcement frame 117C shown in Fig. 39(c), the rear end of the upper flange portion 117b extends to the rear surface of the glass unit 160, and the rear flange portion 117c extending upward from the rear end of the upper flange portion 117b is located behind the glass unit 160. The intermediate reinforcement frame 117C also has the same effects as described above. Further, in this intermediate reinforcement frame 117C, since the width (depth) of the upper flange portion 117b in the front-rear direction is wider than that of the upper flange portion 117b of the above intermediate reinforcement frame 117, the glass unit 160 can be received in a wide range. Note that the intermediate reinforcement frame 117C may be composed of a single sheet metal as shown in the figure, or may be composed of a plurality of sheet metals in the same manner as the above intermediate reinforcement frame 117. Also, a bead portion 117e may be provided on the intermediate reinforcement frame 117C. Further, a locking piece 161b similar to the above may be provided on the glass frame 161 of the glass unit 160.

[0152] (Modification Example 4 of Intermediate Reinforcement Frame) The intermediate reinforcement frame 117D shown in Fig. 40(a) is such that the rear flange portion 117c extends downward from the rear end of the upper flange portion 117b. More specifically, the rear flange portion 117c hangs down from the rear end of the upper flange portion 117b. Also with this configuration, the strength and rigidity of the intermediate reinforcement frame 117D can be increased, and even when the upper plate 201 of the door frame 3 and the lever operation portion 304 are strongly pulled forward, they will not be distorted (plastically deformed). Further, it is possible to place the glass unit 160 on the upper flange portion 117b of the intermediate reinforcement frame 117D. In Fig. 40(a), although it is shown that the rear surface of the rear flange portion 117c does not protrude rearward beyond the rear surface of the glass unit 160, the rear flange portion 117c may protrude rearward beyond the glass unit 160. Also, the intermediate reinforcement frame 117D may be formed of a single sheet metal as shown in the figure, or may be formed of a plurality of sheet metals in the same manner as the above-described intermediate reinforcement frame 117. Further, a bead portion 117e may also be provided on the intermediate reinforcement frame 117D. Also, a locking piece 161b similar to the above may be provided on the glass frame 161 of the glass unit 160.

[0153] (Modification Example 5 of Intermediate Reinforcement Frame) The intermediate reinforcement frame 117E shown in Fig. 40(b) is such that the rear flange portion 117c extends downward from the rear end of the upper flange portion 117b. More specifically, the rear flange portion 117c extends obliquely downward from the rear end of the upper flange portion 117b. Also with this configuration, the strength and rigidity of the intermediate reinforcement frame 117E can be increased, and even when the upper plate 201 of the door frame 3 and the lever operation portion 304 are strongly pulled forward, they will not be distorted (plastically deformed). When the door frame 3 is closed, the rear end side of the rear flange portion 117c of this intermediate reinforcement frame 117E is inserted into the game board 5 (here, within the front constituent member 1000). Due to the insertion of this rear flange portion 117c, a meandering gap will be formed, so even if an illegal tool attempts to intrude along the front surface of the game board 5, it can be blocked by the rear flange portion 117c, and the deterrent force against illegal acts can be increased.

[0154] Incidentally, the rear flange portion 117c of the intermediate reinforcing frame 117E may be brought into contact with the game board 5. Thereby, it becomes possible to position the door frame 3 and the game board 5 via the rear flange portion 117c, or to support the game board 5 by the rear flange portion 117c. Further, when the rear flange portion 117c is brought into contact with the game board 5, it may be connected to the ground. Furthermore, the intermediate reinforcing frame 117E may be composed of a single sheet metal as shown in the figure, or may be composed of a plurality of sheet metals in the same manner as the above-described intermediate reinforcing frame 117. Also, a bead portion 117e may be provided on the intermediate reinforcing frame 117E. Also, a locking piece 161b similar to the above may be provided on the glass frame 161 of the glass unit 160.

[0155] [3-1e-3. Other countermeasure examples] Next, countermeasures against the formation of a gap between the door frame 3 and the main body frame 4 by pulling the upper plate 201 or the like forward will be described. As a specific example 1, for example, a distance sensor (for example, a simple switch, an optical sensor, a magnetic sensor, a proximity sensor, a displacement sensor, etc.) for detecting the distance (change in distance) between the vicinity of the center in the left-right direction of the intermediate reinforcing frame 117 and the game board 5 is provided, and when the signal from the distance sensor exceeds a predetermined threshold value, a notification to that effect may be made. At this time, the distance sensor may be provided on the main body frame 4, may be provided on the game board 5, or may be provided on the door frame 3.

[0156] In Specific Example 1, as described above, since the strength and rigidity of the intermediate reinforcement frame 117 (door frame reinforcement unit 110) are enhanced, even if the door frame 3 is pulled forward with a strong force, it will not plastically deform. However, if it is pulled strongly, it may elastically deform and the distance between the door frame 3 and the game board 5 may change, creating a gap. Therefore, a distance sensor for detecting this distance is provided. As a result, since the change in distance due to elastic deformation can be detected by the distance sensor, it becomes possible to notify that the door frame 3 has been forcibly pulled according to the detection signal from the distance sensor, preventing the player from pulling the door frame 3 too strongly unnecessarily or pulling the door frame 3 strongly for illegal acts, and a pachinko machine 1 with a high crime prevention effect can be provided.

[0157] Also, as Specific Example 2, for example, a door frame opening switch (not shown) provided near the right end in the front surface of the main body frame 4 may be provided behind the vicinity of the center in the left-right direction of the intermediate reinforcement frame 117. As a result, when the upper plate 201 etc. of the door frame 3 is strongly pulled and elastically deformed so that the vicinity of the center in the left-right direction of the intermediate reinforcement frame 117 moves forward, the door frame opening switch detects the opening of the door frame 3 and notifies the fact. In this case, the door frame opening switch may be provided at both the vicinity of the right end of the main body frame 4 and the vicinity of the center in the left-right direction. Also, the door opening switch in the vicinity of the center in the left-right direction may be provided on the game board 5.

[0158] Furthermore, as Specific Example 3, for example, a strain sensor may be provided on the intermediate reinforcement frame 117, and when the signal from the strain sensor exceeds a predetermined threshold value, the fact may be notified.

[0159] Also, as a specific example 4, for example, a hook-shaped intermediate hook (not shown) that moves in conjunction with the door frame hook 652 of the locking unit 650 is provided at a rear part near the center in the left-right direction of the intermediate reinforcement frame 117 in the main body frame 4. When the door frame 3 is closed with respect to the main body frame 4, the intermediate hook may be locked to the intermediate reinforcement frame 117. Thereby, even if the upper plate 201 or the like is pulled forward, it is possible to prevent the vicinity of the center in the left-right direction of the intermediate reinforcement frame 117 from bulging forward (plastic deformation or elastic deformation) due to the locking of the intermediate hook.

[0160] [3-1e-4. Bracketed] The above-described door frame reinforcement unit 110 has the following technical features.

[0161] (Background of Technical Features) A pachinko machine as a gaming machine includes a main body frame that detachably supports a game board from the front, and a door frame that is attached to the main body frame so as to be openable and closable from the front. The door frame is provided so as to be hinge-rotatable on one end side of the left and right front edges of the main body frame, and a window portion closed by a glass plate is provided, and the game area of the game board can be visually recognized from the front through the glass plate.

[0162] In this type of gaming machine, a frame-shaped reinforcing sheet metal formed by combining a plurality of metal plates is provided on the door frame, and a plurality of hooks are locked from the main body frame side to a portion of the open side end edge of the reinforcing sheet metal opposite to the hinge side, so that the door frame cannot be opened even when pulled forward (for example, Patent Document: Japanese Patent Application Laid-Open No. 2008-110159).

[0163] However, in the technology of the above patent document, for example, when a hand is placed on a ball tray (for example, an upper tray, a lower tray, etc.) provided on the front surface of the door frame and pulled forward, there is a risk that the door frame (reinforcing sheet metal) will be distorted so that the center in the left-right direction of the door frame bulges forward. And when the door frame is distorted, a gap is formed between the door frame and the main body frame, and there is a risk that an illegal tool may be inserted into the gaming machine through the gap.

[0164] Therefore, in the following means, in view of the above situation, it is an object to provide a gaming machine capable of preventing illegal acts using the gap by making it difficult to form a gap between the door frame and the main body frame even when the door frame is pulled.

[0165] (Means for Solving Technical Features) Means 1: In a gaming machine, a main body frame that detachably supports a game board having a game area where games are played with game balls from the front, a door frame having a window portion that allows the game area to be visible from the front and is provided to be openable and closable with respect to the main body frame from the front A gaming machine comprising: The door frame is provided with a reinforcing sheet metal unit having a first reinforcing portion extending left and right along the lower side of the window portion, The first reinforcing portion is a substrate portion parallel to the opening surface of the window portion, an upper flange portion extending rearward from the upper edge of the substrate portion, a rear flange portion extending upward or downward from the rear edge of the upper flange portion and is characterized by "including".

[0166] Here, examples of the "first reinforcing portion" include "one made of a single metal plate (sheet metal)", "one made of a plurality of metal plates (sheet metal)", and the like.

[0167] According to the configuration of means 1, it is a gaming machine comprising a main body frame that detachably supports a game board having a game area where games are played by game balls from the front, and a door frame that has a window portion through which the game area can be visually recognized from the front and is provided to be openable and closable with respect to the main body frame from the front. The door frame includes a reinforced sheet metal unit having a first reinforcing portion extending left and right along the lower side of the window portion. The first reinforcing portion includes a substrate portion parallel to the opening surface of the window portion, an upper flange portion extending rearward from the upper edge of the substrate portion, and a rear flange portion extending upward or downward from the rear edge of the upper flange portion. (Refer to the chapter [3-1. Overall configuration of the door frame base unit], the door frame reinforcing unit 110, and the descriptions in FIGS. 35 to 40, etc. in [Embodiments for Carrying Out the Invention].

[0168] As a result, since the reinforced sheet metal unit is provided on the door frame that is provided to be openable and closable with respect to the main body frame from the front, the strength and rigidity of the door frame are enhanced by the reinforced sheet metal unit. This reinforced sheet metal unit has a first reinforcing portion extending in the left-right direction along the lower side of the window portion of the door frame. The first reinforcing portion is provided with a flat substrate portion, an upper flange portion extending rearward from the upper edge of the substrate portion, and a rear flange portion extending upward or downward from the upper flange portion. When the rear flange portion extends upward from the rear edge of the upper flange portion, the cross-sectional shape of the first reinforcing portion becomes a crank shape, and when the rear flange portion extends downward from the rear edge of the upper flange portion, the cross-sectional shape of the first reinforcing portion becomes a U shape. Therefore, the strength and rigidity can be made higher than those of conventional reinforcing portions (reinforced sheet metal) having a linear or L-shaped cross-sectional shape. That is, since the strength and rigidity of the first reinforcing portion of the reinforced sheet metal unit are higher than before, even if the vicinity of the center in the left-right direction of the door frame is strongly pulled forward, the first reinforcing portion will not be distorted (plastically deformed), and no gap will be formed between the door frame and the main body frame. Therefore, even if an attempt is made to perform an illegal act by forming a gap between the door frame and the main body frame by pulling the door frame forward, the door frame will not be distorted by the first reinforcing portion (reinforced sheet metal unit) with enhanced strength and rigidity, and a gaming machine with a high deterrent force against illegal acts can be provided.

[0169] Also, as described above, since the first reinforcing portion (reinforcing sheet metal unit) does not distort even when the vicinity of the center in the left - right direction of the door frame is strongly pulled forward, it is possible to provide a shape that is easy for the player to pull forward (for example, an upper plate, a lower plate, a lever - shaped effect operation portion, a protruding or projecting push - button - shaped effect operation portion, a protruding decorative body, a recessed decorative body, etc.), and it is possible to provide a gaming machine that can make the player enjoy more.

[0170] Note that a glass unit for closing the window portion may be placed on the upper flange portion. Thereby, since the weight of the glass unit can be supported by the upper flange portion (reinforcing sheet metal unit), compared with the case where the glass unit is supported by a resin member (for example, a door frame base) made of synthetic resin that constitutes the door frame, the load on the resin member can be reduced, and early deterioration due to over - load in the resin member can be suppressed.

[0171] Also, when the glass unit is placed on the upper flange portion, if the front surface of the rear flange portion extending upward from the rear edge of the upper flange portion abuts on the rear surface of the glass unit, the rearward movement of the lower end side of the glass unit can be blocked by the rear flange portion. Thereby, if the upper end side of the glass unit is fixed, it can be attached to the door frame, so that the attachment (detachment) of the glass unit can be made easy.

[0172] Furthermore, in the first reinforcing portion, it is desirable that the sum of the lengths in the direction along the respective surfaces of the upper flange portion and the rear flange portion is longer than the length from the substrate portion to the front surface of the game board. Thereby, since the sum of the lengths in the extending directions of the upper flange portion and the rear flange portion is longer than the distance (length) from the substrate portion to the front surface of the game board, the strength and rigidity of the first reinforcing portion can be increased compared with the case where the length is short, and the door frame is less likely to distort even when pulled forward.

[0173] Also, as described above, when the sum of the length of the upper flange portion and the length of the rear flange portion is made longer than the length from the substrate portion to the front surface of the game board, the tip of the rear flange portion can be positioned behind the front surface of the game board. That is, the rear flange portion can be inserted into the game board from the front. Thereby, even if an illegal tool tries to intrude along the front surface of the game board, the intrusion of the illegal tool can be blocked by the rear flange portion inserted into the game board, and a gaming machine with a high deterrent force against illegal acts can be provided.

[0174] Further, it is desirable to provide the first reinforcing portion with a lower flange portion extending forward or backward from the lower edge of the substrate portion. Thereby, in the first reinforcing portion, in addition to providing an upper flange portion extending backward from the upper edge of the substrate portion, a lower flange portion extending forward or backward from the lower edge of the substrate portion is provided. Therefore, the strength and rigidity of the first reinforcing portion can be further increased, and a gaming machine capable of surely achieving the above-described operational effects can be provided.

[0175] Furthermore, it is desirable to make the first reinforcing portion thicker than the sheet metal of other reinforcing portions in the reinforcing sheet metal unit. Thereby, since the sheet thickness of the first reinforcing portion is made thicker than the sheet thickness of other reinforcing portions, the strength and rigidity of the first reinforcing portion can also be increased by this, and a gaming machine capable of achieving the same operational effects as described above can be provided.

[0176] In addition, a game machine may be further provided with a distance sensor for detecting the distance between the first reinforcing portion and the game board. That is, as described above, since the strength and rigidity of the first reinforcing portion (reinforcing sheet metal unit) are enhanced, even if the door frame is pulled forward with a strong force, it will not undergo plastic deformation. However, if it is pulled strongly, it may undergo elastic deformation and the distance between the door frame and the game board may change, creating a gap. Therefore, a distance sensor for detecting that distance may be provided. As a result, since the change in distance due to elastic deformation can be detected by the distance sensor, it becomes possible to notify that the door frame has been forcibly pulled according to the detection signal from the distance sensor, preventing the player from pulling the door frame too strongly unnecessarily or pulling the door frame strongly for the purpose of committing an illegal act, and a game machine with a high anti-theft effect can be provided.

[0177] Means 2: In the configuration of Means 1, "The upper flange portion is provided with a glass unit for closing the window portion" characterized by this.

[0178] According to the configuration of Means 2, a glass unit for closing the window portion is placed on the upper flange portion. (Refer to the description of the upper flange portion 117b and FIG. 37, etc. in [Mode for Carrying Out the Invention])

[0179] As a result, since the weight of the glass unit can be supported by the upper flange portion (reinforcing sheet metal unit), compared with the case where the glass unit is supported by a resin member (for example, a door frame base) made of synthetic resin that constitutes the door frame, the load on the resin member can be reduced, and early deterioration due to overload in the resin member can be suppressed.

[0180] In addition, since the glass unit is placed on the upper flange portion, when the front surface of the rear flange portion extending upward from the rear end edge of the upper flange portion abuts against the rear surface of the glass unit, the rearward movement of the lower end side of the glass unit can be blocked by the rear flange portion. Thereby, if the upper end side of the glass unit is fixed, it can be attached to the door frame, so that the attachment (detachment) of the glass unit can be made easy.

[0181] Means 3: In the configuration of Means 1 or Means 2, "The first reinforcing portion is The sum of the lengths in the direction along the respective surfaces of the upper flange portion and the rear flange portion is longer than the length from the substrate portion to the front surface of the game board" It is characterized by this.

[0182] According to the configuration of Means 3, in the first reinforcing portion, the sum of the lengths in the direction along the respective surfaces of the upper flange portion and the rear flange portion is made longer than the length from the substrate portion to the front surface of the game board. (In [Embodiments for Carrying Out the Invention], refer to the description of the intermediate reinforcing frame 117 and FIG. 38, etc.)

[0183] Thereby, since the sum of the lengths in the extending directions of the upper flange portion and the rear flange portion is made longer than the distance (length) from the substrate portion to the front surface of the game board, the strength and rigidity of the first reinforcing portion can be increased as compared with the case where the length is short, and the door frame can be made less likely to be distorted even when pulled forward.

[0184] In addition, since the sum of the length of the upper flange portion and the length of the rear flange portion is made longer than the length from the substrate portion to the front surface of the game board, the tip of the rear flange portion can be positioned behind the front surface of the game board. That is, the rear flange portion can be inserted into the game board from the front. Thereby, even if an illegal tool tries to intrude along the front surface of the game board, the intrusion of the illegal tool can be blocked by the rear flange portion inserted into the game board, and a gaming machine with a high deterrent force against illegal acts can be provided.

[0185] Means 4: In any one of the configurations from Means 1 to Means 3, "The first reinforcing portion is provided with a lower flange portion extending forward or backward from the lower edge of the substrate portion." It is characterized by this.

[0186] According to the configuration of Means 4, the first reinforcing portion is provided with a lower flange portion extending forward or backward from the lower edge of the substrate portion. (Refer to the description of the lower flange portion 117d and FIG. 36 in [Embodiments of the Invention])

[0187] Thereby, in the first reinforcing portion, in addition to providing an upper flange portion extending backward from the upper edge of the substrate portion, a lower flange portion extending forward or backward from the lower edge of the substrate portion is provided. Therefore, the strength and rigidity of the first reinforcing portion can be further increased, and a gaming machine capable of surely achieving the above-described operational effects can be provided.

[0188] Means 5: In any one of the configurations from Means 1 to Means 4, "The first reinforcing portion has a greater plate thickness than the sheet metal of the other reinforcing portions in the reinforcing sheet metal unit." It is characterized by this.

[0189] According to the configuration of Means 5, the first reinforcing portion has a greater plate thickness than the sheet metal of the other reinforcing portions in the reinforcing sheet metal unit. (Refer to the description of the intermediate reinforcing frame 117 and FIG. 36 in [Embodiments of the Invention])

[0190] Thereby, since the plate thickness of the first reinforcing portion is greater than that of the other reinforcing portions, the strength and rigidity of the first reinforcing portion can also be increased by this, and a gaming machine capable of achieving the same operational effects as described above can be provided.

[0191] Note that the first reinforcing part may have a thick plate thickness over the entire length in the left-right direction, or may have a thick plate thickness in a part of the entire length in the left-right direction (for example, a predetermined range from the center in the left-right direction).

[0192] Means 6: In any one of the configurations from Means 1 to Means 5, "a distance sensor for detecting the distance between the first reinforcing part and the game board, is further provided", which is characterized.

[0193] Here, examples of the "distance sensor" include a "switch", an "optical sensor", a "magnetic sensor", a "proximity sensor", a "displacement sensor", etc. The distance sensor may be provided on the first reinforcing part (door frame), on the game board, or on the main body frame. As the switch as the distance sensor, for example, a switch (door opening switch) used for a door opening sensor may be used. By using a switch similar to the door opening sensor, the input circuit may be designed in the same way as the input circuit of the door opening sensor or the like. Also, since it is a simple contact, depending on the connection method, it is possible to collectively process a plurality of inputs by a simple connection such as a wired OR.

[0194] According to the configuration of Means 6, the gaming machine further includes a distance sensor for detecting the distance between the first reinforcing part and the game board. (Refer to the chapter of [3-1e-3. Other countermeasure examples] in [Mode for Carrying Out the Invention])

[0195] In this configuration, as described above, since the strength and rigidity of the first reinforcing portion (reinforcing sheet metal unit) are enhanced, the door frame does not plastically deform even when pulled forward with a strong force. However, if it is pulled strongly, it may elastically deform and the distance between the door frame and the game board may change, creating a gap. Therefore, a distance sensor for detecting this distance is provided. As a result, since the change in the distance due to elastic deformation can be detected by the distance sensor, it becomes possible to notify that the door frame has been forcibly pulled according to the detection signal from the distance sensor, and it is possible to prevent the player from pulling the door frame too strongly unnecessarily or pulling the door frame strongly for the purpose of committing an illegal act, and it is possible to provide a gaming machine with a high anti-theft effect.

[0196] As described above, according to the above-described solution means, it is possible to provide a gaming machine capable of preventing an illegal act using the gap by making it difficult to form a gap between the door frame and the main body frame even when the door frame is pulled.

[0197] (Relationship between the solution means of the technical features and the embodiments) The door window 101a of the door frame base 101 in the door frame base unit 100 of the door frame 3 of the present embodiment corresponds to the window portion of the above-described solution means, the door frame reinforcement unit 110 of the door frame base unit 100 in the present embodiment corresponds to the reinforcing sheet metal unit of the above-described solution means, and the intermediate reinforcement frame 117 (intermediate reinforcement frames 117A to 117E) of the door frame reinforcement unit 110 in the present embodiment corresponds to the first reinforcing portion of the above-described solution means, respectively.

[0198] (Characteristic operational effects of the present embodiment) According to the pachinko machine 1 of this embodiment, since a door frame reinforcing unit 110 combining a plurality of metal plates is provided on a door frame 3 that is openable and closable from the front with respect to a main body frame 4, the strength and rigidity of the door frame 3 are enhanced by the door frame reinforcing unit 110. This door frame reinforcing unit 110 has an intermediate reinforcing frame 117 extending in the left-right direction along the lower side of a door window 101a of the door frame 3. The intermediate reinforcing frame 117 is provided with a flat plate-shaped substrate portion 117a, an upper flange portion 117b extending rearward from the upper edge of the substrate portion 117a, and a rear flange portion 117c extending upward or downward from the upper flange portion 117b. When the rear flange portion 117c extends upward from the rear edge of the upper flange portion 117b, the cross-sectional shape of the intermediate reinforcing frame 117 (intermediate reinforcing frame 117A, intermediate reinforcing frame 117B, intermediate reinforcing frame 117C) becomes a crank shape. When the rear flange portion 117c extends downward from the rear edge of the upper flange portion 117b, the cross-sectional shape of the intermediate reinforcing frame 117D (intermediate reinforcing frame 117E) becomes a U shape. Therefore, the strength and rigidity can be made higher than those of a conventional reinforcing portion (intermediate reinforcing frame) having a linear or L-shaped cross-sectional shape. That is, since the strength and rigidity of the intermediate reinforcing frame 117 of the door frame reinforcing unit 110 are enhanced compared to the conventional case, even if the vicinity of the center in the left-right direction of the door frame 3 is strongly pulled forward, the intermediate reinforcing frame 117 will not be distorted (plastically deformed), and no gap will be formed between the door frame 3 and the main body frame 4. Therefore, even if an attempt is made to form a gap between the door frame 3 and the main body frame 4 by pulling the door frame 3 forward to perform an illegal act, the door frame 3 will not be distorted to form a gap with the main body frame 4 due to the intermediate reinforcing frame 117 (door frame reinforcing unit 110) having enhanced strength and rigidity, and a pachinko machine 1 with a high deterrent force against illegal acts can be provided.

[0199] In addition, as described above, since the intermediate reinforcement frame 117 (door frame reinforcement unit 110) does not distort even when the vicinity of the center in the left - right direction of the door frame 3 is strongly pulled forward, it is possible to provide a shape that is easy for the player to pull forward (for example, the upper tray 201, the lower tray 202, the lever - shaped effect operation unit (lever operation unit 304), the protruding or projecting push - button - shaped effect operation unit (pressing operation unit 303), the protruding decorative body, the recessed decorative body, etc.). Thus, it is possible to provide a pachinko machine 1 that can make the player enjoy more.

[0200] Furthermore, since the glass unit 160 for closing the door window 101a is placed on the upper flange portion 117b, the weight of the glass unit 160 can be supported by the upper flange portion 117b (door frame reinforcement unit 110). Therefore, compared with the case where the glass unit 160 is supported by the resin member (for example, the door frame base 101) made of synthetic resin that constitutes the door frame 3, the load on the resin member can be reduced, and early deterioration due to over - load in the resin member can be suppressed.

[0201] Also, the glass unit 160 is placed on the upper flange portion 117b, and the rear surface of the glass unit 160 abuts against the front surface of the rear flange portion 117c that extends upward from the rear - end edge of the upper flange portion 117b. Therefore, the rearward movement of the lower - end side of the glass unit 160 can be blocked by the rear flange portion 117c. As a result, if only the upper - end side of the glass unit 160 is fixed, it can be attached to the door frame 3, so that the attachment (detachment) of the glass unit 160 can be made easy.

[0202] Furthermore, in the intermediate reinforcement frame 117, since the sum (L0) of the lengths (L1 and L2) in the direction along the respective surfaces of the upper flange portion 117b and the rear flange portion 117c is made longer than the length from the substrate portion 117a to the front surface of the game board 5, the strength and rigidity of the intermediate reinforcement frame 117 can be increased compared with the case where the length is short, and the door frame 3 can be made less likely to distort even when pulled forward.

[0203] Also, since the sum (L0) of the length L1 of the upper flange portion 117b and the length L2 of the rear flange portion 117c is made longer than the length from the substrate portion 117a to the front surface of the pachinko game board 5, the tip of the rear flange portion 117c can be positioned behind the front surface of the pachinko game board 5. That is, the rear flange portion 117c can be inserted into the pachinko game board 5 from the front, like the intermediate reinforcing frame 117E. Thereby, even if an illegal tool tries to intrude along the front surface of the pachinko game board 5, the intrusion of the illegal tool can be blocked by the rear flange portion 117c inserted into the pachinko game board 5, and a pachinko machine 1 with a high deterrent force against illegal acts can be provided.

[0204] Also, since the intermediate reinforcing frame 117 is provided with a lower flange portion 117d extending forward or backward from the lower edge of the substrate portion 117a in addition to the upper flange portion 117b side, the strength and rigidity of the intermediate reinforcing frame 117 can be further increased, and a pachinko machine 1 capable of surely achieving the above-described operational effects can be provided.

[0205] Furthermore, since the intermediate reinforcing frame 117 is made thicker than the sheet metal of the other reinforcing portions (left reinforcing frame 111, right reinforcing frame 112, upper reinforcing frame 113) in the door frame reinforcing unit 110, the strength and rigidity of the intermediate reinforcing frame 117 (door frame reinforcing unit 110) can also be increased by this, and a pachinko machine 1 capable of achieving the same operational effects as described above can be provided.

[0206] Furthermore, an interval sensor for detecting the interval between the intermediate reinforcing frame 117 and the game board 5 may be further provided. That is, as described above, since the strength and rigidity of the intermediate reinforcing frame 117 (door frame reinforcing unit 110) are enhanced, the door frame 3 will not plastically deform even when pulled forward with a strong force. However, if pulled strongly, it may elastically deform and the interval between the door frame 3 and the game board 5 may change, creating a gap. Therefore, an interval sensor for detecting that interval is provided. As a result, since the change in the interval due to elastic deformation can be detected by the interval sensor, it becomes possible to notify that the door frame 3 has been forcibly pulled according to the detection signal from the interval sensor, preventing the player from pulling the door frame 3 too strongly unnecessarily or pulling the door frame 3 strongly for illegal acts, and a pachinko machine 1 with a high crime prevention effect can be provided.

[0207] [3-1f. Upper hinge assembly on door frame] The upper hinge assembly 120 on the door frame of the door frame base unit 100 will be mainly described with reference to FIGS. 34 and 35. The upper hinge assembly 120 on the door frame is attached to the upper left corner of the front view of the door frame reinforcing unit 110. The upper hinge assembly 120 on the door frame is for attaching the door frame 3 to the main body frame 4 so as to be hinge-rotatable in cooperation with the lower hinge member 125 of the door frame. The upper hinge assembly 120 on the door frame includes a hinge bracket 121 attached to the door frame reinforcing unit 110, an upper hinge pin 122 of the door frame movably attached to the hinge bracket 121 in the vertical direction, a flange member 123 attached to the upper hinge pin 122 of the door frame, and a lock spring 124 biasing the upper hinge pin 122 of the door frame to move upward.

[0208] The hinge bracket 121 includes a flat mounting piece 121a having a rectangular shape in the front view and flat protruding pieces 121b extending forward from the upper and lower sides of the mounting piece 121a. The hinge bracket 121 has the mounting piece 121a attached to the door frame reinforcing unit 110. The hinge bracket 121 is formed by bending a metal plate.

[0209] The hinge pin 122 on the door frame is a cylindrical metal rod bent into an L shape. In the state where the hinge pin 122 on the door frame is assembled to the hinge assembly 120 on the door frame, the portion extending vertically penetrates from below near the front ends of the pair of protruding pieces 121b in the hinge bracket 121, and the upper end extends upward beyond the upper protruding piece 121b. At the same time, the portion extending horizontally abuts against the lower surface of the lower protruding piece 121b. The upper end of the hinge pin 122 on the door frame is rotatably inserted into the hinge hole 511a for the door frame of the upper hinge body 511 in the hinge member 510 on the main body frame of the main body frame 4.

[0210] The collar member 123 is an E-ring and is attached to the portion between the pair of protruding pieces 121b of the hinge pin 122 on the door frame. The lock spring 124 is formed in a coil shape and is placed around the portion of the hinge pin 122 on the door frame that extends vertically between the collar member 123 and the lower protruding piece 121b of the hinge bracket 121. By this lock spring 124, the hinge pin 122 on the door frame is biased upward via the collar member 123.

[0211] The hinge assembly 120 on the door frame is in a state where the hinge pin 122 on the door frame is biased upward by the lock spring 124. The horizontal portion at the lower end of the hinge pin 122 on the door frame abuts against the lower surface of the lower protruding piece 121b, thereby restricting further upward movement. In this state, the upper end of the hinge pin 122 on the door frame protrudes upward by a predetermined amount from the upper surface of the upper protruding piece 121b.

[0212] The door frame upper hinge assembly 120 can move the horizontally extending part at the lower end of the door frame upper hinge pin 122 downward against the biasing force of the lock spring 124, thereby moving the entire door frame upper hinge pin 122 downward, and the upper end of the door frame upper hinge pin 122 can be submerged below the upper surface of the upper protruding piece 121b. Therefore, the door frame upper hinge assembly 120 can insert or remove the upper end of the door frame upper hinge pin 122 into or from the door frame upper hinge hole 511a of the main body frame upper hinge member 510 from below. By inserting the upper end of the door frame upper hinge pin 122 into the door frame upper hinge hole 511a of the main body frame upper hinge member 510, the upper left end of the door frame 3 in the front view can be supported by the main body frame 4 so as to be hinge-rotatable.

[0213] Also, in the door frame upper hinge assembly 120, the vertically extending part of the door frame upper hinge pin 122 is coaxially positioned with the door frame lower hinge pin 126 of the door frame lower hinge member 125 described later. Thus, the door frame 3 can be hinge-rotated with respect to the main body frame 4 in a good state by the door frame upper hinge pin 122 and the door frame lower hinge pin 126.

[0214] [3-1g. Door Frame Lower Hinge Member] The door frame lower hinge member 125 of the door frame base unit 100 will be mainly described with reference to FIGS. 34 and 35. The door frame lower hinge member 125 is attached to the lower left corner in the front view of the door frame reinforcement unit 110. The door frame lower hinge member 125 is for attaching the door frame 3 to the main body frame 4 so as to be hinge-rotatable in cooperation with the door frame upper hinge assembly 120.

[0215] The door frame lower hinge member 125 includes a mounting piece 125a that is attached to the door frame reinforcement unit 110 and is rectangular in the front view and flat plate-shaped, a flat plate-shaped protruding piece 125b that extends forward from the lower side of the mounting piece 125a, and a door frame lower hinge pin 126 (see FIG. 35, etc.) that protrudes downward from the lower surface near the front end of the protruding piece 125b.

[0216] The attachment piece 125a and the protruding piece 125b of the lower hinge member 125 of the door frame are formed by bending a metal plate. The lower hinge pin 126 of the door frame is a columnar metal rod, and a tapered chamfer is provided on the outer periphery of the lower end portion. This lower hinge pin 126 of the door frame is attached to a portion that is coaxial with a portion extending above and below the upper hinge pin 122 of the upper hinge assembly 120 of the door frame in the protruding piece 125b in a state of being assembled to the door frame base unit 100.

[0217] By inserting the lower hinge pin 126 of this door frame into the lower hinge hole 522a for the door frame of the main body frame lower hinge assembly 520, the door frame 3 can be supported so as to be hinge-rotatable with respect to the main body frame 4.

[0218] [3-1h. Cylinder Lock] The cylinder lock 130 in the door frame base unit 100 of the door frame 3 will be described in detail mainly with reference to FIGS. 41 to 43. FIG. 41(a) is a perspective view of the cylinder lock of the door frame seen from the front, (b) is a perspective view of the cylinder lock of (a) seen from the back and front, (c) is a perspective view of the cylinder lock in a conventional pachinko machine seen from the front, and (d) is a perspective view of the cylinder lock of (a) seen from the back. FIG. 42(a) is an exploded perspective view of the cylinder lock of FIG. 41(a) seen from the front, and (b) is an exploded perspective view of the cylinder lock of FIG. 41(a) seen from the back. FIG. 43(a) is an explanatory view showing the movable mechanism of the cylinder lock of FIG. 41(a) from the front, (b) is an explanatory view of the cylinder lock shown in a state rotated 90 degrees counterclockwise from the state of (a), and (c) is an explanatory view of the cylinder lock shown in a state rotated 90 degrees clockwise from the state of (a).

[0219] The cylinder lock 130 is attached to the cylinder mounting frame 115 of the door frame reinforcement unit 110 and is used in cooperation with the locking unit 650 of the main body frame 4 to open and close the door frame 3 and the main body frame 4, and to lock and unlock the outer frame 2 and the main body frame 4. The cylinder lock 130 includes a columnar cylinder body 131 extending in the front-rear direction, a keyhole 132 formed on the front end face of the cylinder body 131, and a rotation transmission member 133 provided behind the cylinder body 131 and rotating together when a regular key inserted into the keyhole 132 is rotated.

[0220] The cylinder body 131 of the cylinder lock 130 penetrates the front part of the cylinder mounting frame 115 from the rear, and the rear end is attached to the front part. The rotation transmission member 133 is formed in a cylindrical shape with an open rear (specifically, a conical cylindrical shape with a diameter increasing toward the rear), and has a pair of notches cut from the rear end toward the front at positions facing each other across the central axis. The rotation transmission member 133 is formed such that the transmission cylinder 654 of the locking unit 650 in the main body frame 4 is inserted from the rear, and when a pair of protrusions of the transmission cylinder 654 are inserted into the pair of notches, the rotation of the rotation transmission member 133 (the key inserted into the keyhole 132) can be transmitted to the transmission cylinder 654 to cause it to rotate.

[0221] More specifically, the cylinder lock 130 includes a first cam member 134 provided on the rear end side of the cylinder body 131 and rotating together when a regular key inserted into the keyhole 132 is rotated, a second cam member 135 rotatably attached around the axis in the front-rear direction at a position below the cylinder body 131 in the cylinder mounting frame 115, a strip-shaped first arm 136 with the upper end side rotatably attached at a position to the right of the rotation center of the first cam member 134 and the lower end side rotatably attached at a position to the right of the rotation center of the second cam member 135, and a strip-shaped second arm 137 with the upper end side rotatably attached at a position below the rotation center of the first cam member 134 and the lower end side rotatably attached at a position below the rotation center of the second cam member 135.

[0222] In addition, the cylinder tablet 130 is attached to the cylinder mounting frame 115 so as to cover the cylinder main body 131, the first cam member 134, the first arm 136, and the second arm 137 from the rear, excluding the second cam member 135 (rotation transmission member 133), and includes a rear cover 138 and rivets 139 that rotatably attach the upper and lower ends of the first arm 136 and the second arm 137 to the first cam member 134 and the second cam member 135, respectively.

[0223] The upper end side of the first arm 136 is attached to the rear surface side of the first cam member 134, and the upper end side of the second arm 137 is attached to the front surface side. The second cam member 135 is rotatably attached to the cylinder mounting frame 115 from the rear side, and a rotation transmission member 133 is integrally and rotatably attached to the rear side sandwiching the front surface of the cylinder mounting frame 115. The lower end side of the first arm 136 is attached to the front surface side of the second cam member 135, and the lower end side of the second arm 137 is attached to the front surface side in front of the first arm 136.

[0224] In each of the first cam member 134 and the second cam member 135, the portion where the first arm 136 is attached and the portion where the second arm 137 is attached are separated by an angle of 90 degrees around their respective rotation axes. Also, in each of the first cam member 134 and the second cam member 135, the portion where the first arm 136 is attached is provided at a position farther from the rotation center than the portion where the second arm 137 is attached.

[0225] The rear cover 138 is detachably attached to the cylinder mounting frame 115 by a screw (not shown) at the upper end side with shaft portions 138a protruding cylindrically outward from the lower ends of both left and right side surfaces locked to the L-shaped locking slits 115b of the cylinder mounting frame 115.

[0226] This cylinder lock 130 is formed of metal, including a cylinder mounting frame 115, a cylinder body 131, a rotation transmission member 133, a first cam member 134, a second cam member 135, a first arm 136, and a second arm 137.

[0227] When the cylinder lock 130 is assembled to the door frame 3, the front end of the cylinder body 131 substantially coincides with the front end of the cylinder insertion port 440b of the door frame right side unit 430.

[0228] Here, the conventional cylinder lock 130A will be described. As shown in FIGS. 41(c) and (d), in the conventional cylinder lock 130A, the cylinder body 131 penetrates the front piece of the cylinder mounting frame 115A from the rear, and the rear end is attached to the front piece. A rotation transmission member 133 is provided on the axis of the cylinder body 131 of this cylinder lock 130A.

[0229] Subsequently, the operation of the cylinder lock 130 of the present embodiment will be described. In the conventional cylinder lock 130, as shown in FIGS. 41(c) and (d), the rotation transmission member 133 is provided on the axis of the cylinder body 131, whereas in the cylinder lock 130 of the present embodiment, as shown in FIGS. 41(a) and (b), etc., the rotation transmission member 133 is provided at a position separated downward from the axis of the cylinder body 131.

[0230] In the normal state of this cylinder lock 130, as shown in FIG. 43(a), both the upper and lower ends of the first arm 136 are attached to the respective right-side parts of the rotation centers of the first cam member 134 and the second cam member 135, and both the upper and lower ends of the second arm 137 are attached to the respective lower-side parts of the rotation centers of the first cam member 134 and the second cam member 135. In the cylinder body 131, it can be rotated by 90 degrees in the clockwise and counterclockwise directions respectively from the normal state by a regular key.

[0231] In this state, when the key inserted into the keyhole 132 rotates the first cam member 134 counterclockwise through the cylinder of the cylinder body 131, the first arm 136 and the second arm 137 will move upward. At this time, in the first arm 136, since the upper end side is attached to the right of the rotation center of the first cam member 134, a large force acts on the first arm 136 to rotate the second cam member 135 counterclockwise. On the other hand, in the second arm 137, since the upper end side is attached below the rotation center of the first cam member 134, almost no force acts on the second arm 137 to rotate the second cam member 135 counterclockwise.

[0232] In this way, when the first cam member 134 rotates counterclockwise from the normal state, the force is mainly transmitted through the first arm 136, the second cam member 135 rotates counterclockwise, and the rotation transmission member 133 rotates together with the second cam member 135. The upward force generated by the counterclockwise rotation of the first cam member 134 is proportional to the horizontal distance between the parts where the first arm 136 and the second arm 137 are attached to the first cam member 134 and the rotation center of the first cam member 134. Therefore, as the first cam member 134 rotates counterclockwise from the normal state, the upward force acting on the first arm 136 decreases, while the upward force acting on the second arm 137 increases.

[0233] Therefore, when the rotation angle of the first cam member 134 from the normal state counterclockwise exceeds 45 degrees, the upward force acting on the second arm 137 is greater than that acting on the first arm 136, and mainly through the second arm 137, the second cam member 135 rotates counterclockwise. And the key inserted into the keyhole 132 can be rotated counterclockwise from the normal state up to an angle of 90 degrees (see Fig. 43(b)).

[0234] Note that when returning to the normal state by rotating 90 degrees in the clockwise direction from the state where it is rotated 90 degrees counterclockwise from the normal state by the key, it will operate by the reverse action of the above.

[0235] On the other hand, when the first cam member 134 is rotated in the clockwise direction through the cylinder of the cylinder body 131 by the key inserted into the keyhole 132 from the normal state, the first arm 136 with the upper end side attached to the right side of the rotation center of the first cam member 134 moves downward, and the second arm 137 with the upper end side attached below the rotation center of the first cam member 134 moves upward. At this time, in the first arm 136, since the upper end side is attached to the right side of the rotation center of the first cam member 134, a large force to rotate the second cam member 135 in the clockwise direction acts on the first arm 136, while in the second arm 137, since the upper end side is attached below the rotation center of the first cam member 134, almost no force to rotate the second cam member 135 in the clockwise direction acts from the second arm 137.

[0236] In this way, when the first cam member 134 rotates in the clockwise direction from the normal state, the force is mainly transmitted through the first arm 136, the second cam member 135 rotates in the clockwise direction, and the rotation transmission member 133 rotates together with the second cam member 135. The force for transmitting the rotation of the first cam member 134 by the first arm 136 and the second arm 137 to the second cam member 135 is proportional to the lateral distance between the parts where the first arm 136 and the second arm 137 are attached to the first cam member 134 and the rotation center of the first cam member 134. Therefore, as the first cam member 134 rotates in the clockwise direction from the normal state, the force to rotate the second cam member 135 becomes smaller in the first arm 136, while the force to rotate the second cam member 135 becomes larger in the second arm 137.

[0237] Therefore, when the rotation angle of the first cam member 134 from the normal state in the clockwise direction exceeds 45 degrees, the force of the second arm 137 to rotate the second cam member 135 becomes greater than that of the first arm 136, and mainly through the second arm 137, the second cam member 135 rotates in the clockwise direction. And the key inserted into the keyhole 132 can be rotated from the normal state to an angle of 90 degrees in the clockwise direction (see Fig. 43(c)).

[0238] Note that when the key is rotated 90 degrees in the clockwise direction from the state where it is rotated 90 degrees in the clockwise direction from the normal state and then returned to the normal state, it will operate by the reverse action of the above.

[0239] As described above, according to the cylinder lock 130 of the present embodiment, the first cam member 134 and the second cam member 135 are connected by the first arm 136 and the second arm 137 attached with a phase difference of 90 degrees from each other to transmit rotation. Therefore, no matter what rotational position the first cam member 134 (the key inserted into the keyhole 132) is in, rotation can be transmitted by at least one of the first arm 136 and the second arm 137 to rotate the second cam member 135 (the rotation transmission member 133), and the locking and unlocking of the door frame 3 and the main body frame 4 can be made good.

[0240] Also, according to the cylinder lock 130 of the present embodiment, by transmitting rotation by the first arm 136 and the second arm 137 as a rotation transmission mechanism, the axis of the rotation transmission member 133 (the transmission cylinder 654 of the locking unit 650 in the main body frame 4) can be provided at different positions with respect to the axis of the cylinder main body 131. Therefore, without changing the locking unit 650, the position of the cylinder main body 131 in the door frame 3 can be changed to an arbitrary position, and the cylinder main body 131 (the keyhole 132) can be provided at a position that does not interfere with the decoration of the door frame 3, and a pachinko machine 1 with high decorativeness of the door frame 3 can be provided.

[0241] Also, as described above, even if the position of the cylinder body 131 is changed in the door frame 3, it is not necessary to change the locking unit 650 in the main body frame 4. Therefore, the locking unit 650 can be diverted, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0242] By the way, in the conventional cylinder lock 130A, since the rotation transmission member 133 is provided behind the cylinder body 131, a person who knows the configuration may insert a tool from the front to the rear of the cylinder body 131 and illegally rotate the rotation transmission member 133 with the tool, thereby opening the door frame 3 and committing an illegal act. On the other hand, in the cylinder lock 130 of the present embodiment, since the rotation transmission member 133 is provided at a position away from the axis (rear) of the cylinder body 131, even if an attempt is made to insert a tool behind the cylinder body 131 and rotate the rotation transmission member 133, since the rotation transmission member 133 does not exist at that part, the rotation transmission member 133 cannot be rotated, and it is possible to prevent an illegal act of opening the door frame 3, the main body frame 4, etc.

[0243] Furthermore, in the cylinder lock 130, since the second arm 137 connects the portions of the first cam member 134 and the second cam member 135 that are separated by a rotation angle of 90 degrees with respect to the first arm 136, even if the portion of one of the first arm 136 or the second arm 137 attached to the first cam member 134 and the second cam member 135 is located on the straight line connecting the center of the first cam member 134 and the center of the second cam member 135, the other of the first arm 136 or the second arm 137 is in a state of connecting the portions that are farthest from the straight line connecting the center of the first cam member 134 and the center of the second cam member 135. Therefore, even if one of the first arm 136 or the second arm 137 is located at the dead center of the first cam member 134 and the second cam member 135 and cannot transmit the rotation from the first cam member 134 to the second cam member 135, the other of the first arm 136 or the second arm 137 can transmit the rotation from the first cam member 134 to the second cam member 135. Thus, no large resistance is applied to the rotation of the first cam member 134, the key inserted into the keyhole 132 can be smoothly rotated, the locking and unlocking can be easily performed, the key inserted into the keyhole can be prevented from being forced to rotate, and the breakage of the key can be prevented.

[0244] Also, since the rotation of the key inserted into the keyhole 132 is transmitted to the rotation transmission member 133 provided at an eccentric position by the two arms of the first arm 136 and the second arm 137, even if one arm is damaged for some reason, the rotation can be transmitted by the remaining arm, and the pachinko machine 1 having the highly reliable cylinder lock 130 can be provided.

[0245] In addition, since the smooth rod-shaped (strip-shaped) first arm 136 and second arm 137 are configured to transmit the rotation of the key inserted into the keyhole 132 to the rotation transmission member 133 provided at an eccentric position, when the rotation is transmitted by gears, there is a risk that the gear will rotate by hooking the tip of the tool on the teeth of the gear and the rotation transmission member 133 will be rotated. However, since the first arm 136 and the second arm 137 are rod-shaped with smooth surfaces, it is possible to make it difficult for the tip of the tool to catch on the first arm 136 or the second arm 137, and it is possible to avoid the rotation transmission member 133 being rotated by the movement of the first arm 136 or the second arm 137, and it is possible to surely prevent the locking unit 650 from being illegally operated and the door frame 3 and the main body frame 4 from being unlocked.

[0246] In the cylinder lock 130 of the present embodiment, although the first arm 136 and the second arm 137 are used as the rotation transmission mechanism for transmitting the rotation of the first cam member 134 to the second cam member 135, the present invention is not limited thereto. For example, a rotation transmission mechanism using a plurality of gears, a rotation transmission mechanism using a gear and a rack gear, a rotation transmission mechanism using a sprocket and a chain, a rotation transmission mechanism using a pulley and a belt, etc. may be used.

[0247] [3-1i. Ball Feeding Unit] The ball feeding unit 140 of the door frame base unit 100 will be described in detail mainly with reference to FIGS. 44 and 45. FIG. 44(a) is a perspective view of the ball feeding unit of the door frame base unit seen from the front, and (b) is a perspective view of the ball feeding unit seen from the rear. FIG. 45(a) is an exploded perspective view of the ball feeding unit seen from the front, and (b) is an exploded perspective view of the ball feeding unit with the rear case and the anti-tampering member removed seen from the rear. The ball feeding unit 140 can supply the game balls B supplied one by one from the upper tray 201 of the tray unit 200 to the ball launching device 540 of the main body frame 4, and can also remove the game balls B stored in the upper tray 201 to the lower tray 202 by operating the upper tray ball removal button 222.

[0248] The ball feeding unit 140 has a front cover 141 which is box-shaped with its rear open, having a ball inlet 141a through which the game ball B is supplied from the upper plate 201 of the dish unit 200 and penetrates in the front-rear direction, and a ball outlet 141b that opens below the ball inlet 141a; a rear cover 142 which is box-shaped with its front open and its rear closed, having a hitting ball supply port 142a for supplying the game ball B that has entered from the ball inlet 141a of the front cover 141 and penetrates in the front-rear direction to the ball launching device 540; a ball discharging member 143 which is pivotally supported about an axis extending in the front-rear direction between the rear cover 142 and the front cover 141 and has a partition portion 143a that partitions between the ball inlet 141a and the ball outlet 141b on the rear side of the front cover 141; a ball feeding member 144 which is rotatably supported about an axis extending in the vertical direction between the front cover 141 and the rear cover 142 and feeds the game balls B on the partition portion 143a of the ball discharging member 143 one by one to the hitting ball supply port 142a of the rear cover 142; and a ball feeding solenoid 145 for rotating the ball feeding member 144.

[0249] As shown in the figure, in the front view of this ball feeding unit 140, the ball feeding member 144 is arranged on the right side of the ball inlet 141a, the ball discharging member 143 is arranged on the left side of the ball feeding member 144, and the ball feeding solenoid 145 is arranged on the right side of the ball feeding member 144.

[0250] The front cover 141 of the ball feeding unit 140 is provided with an arc-shaped slit 141c formed concentrically with respect to the rotation center of the ball discharging member 143 on the left side of the ball outlet 141b in the front view, and the operating rod 143c of the ball discharging member 143 described later extends forward from this slit 141c. Also, the upper edge of the front cover 141 extends upward from the upper edge of the ball inlet 141a, and when the door frame 3 is assembled, it is formed to close from the rear the part that is open to the rear at the upstream end side of the ball feeding guide path and the ball discharging guide path 241c of the rear base 241 in the upper plate ball discharging rear unit 240.

[0251] The ball discharging member 143 includes a partition portion 143a that partitions the space between the inlet 141a and the ball discharging port 141b below the inlet 141a, with the upper surface of the partition sloping downward toward the ball feeding member 144; a rotating paddle portion 143b that extends downward from the end of the partition portion 143a opposite to the ball feeding member 144, bends in a U-shape from near the middle in the vertical direction toward the lower center of the ball discharging port 141b, and is rotatably supported about an axis with its lower end extending in the front-rear direction; a rod-shaped operating paddle 143c that protrudes forward from the upper end of the rotating paddle portion 143b; and a weight portion 143d that protrudes from the side surface of the rotating paddle portion 143b below the operating paddle 143c to the side opposite to the partition portion 143a. The operating paddle 143c of the ball discharging member 143 is formed to protrude forward through an arcuate slit 141c formed in the front cover 141 (see Fig. 44(a)). The operating paddle 143c abuts against the upper end (upper surface) of an operating transmission portion 242b of an upper plate ball discharging slider 242 that moves downward by pressing an upper plate ball discharging button 222 of the dish unit 200 through a ball feeding opening 101e of the door frame base 101.

[0252] The ball feeding member 144 includes a blocking portion 144a that faces the inlet 141a and the partition portion 143a of the ball discharging member 143, extends in the vertical direction, and has a fan-shaped view in plan about a rotation axis; a ball holding portion 144b that is recessed in an arc shape from the rear end of the blocking portion 144a toward the rotation axis side; and a rod-shaped paddle portion 144c that extends downward from the rear end of the ball holding portion 144b. The blocking portion 144a and the ball holding portion 144b of the ball feeding member 144 are formed adjacent to each other within an angular range of approximately 180° about the rotation axis. Also, the ball holding portion 144b of the ball feeding member 144 is sized to hold one game ball B. The ball feeding member 144 rotates about the rotation axis by moving the paddle portion 144c, which is arranged at a position eccentric from the rotation axis, in the left-right direction by driving a ball feeding solenoid 145.

[0253] This ball feeding member 144 is configured to rotate between a supply position where the blocking portion 144a faces the partition portion 143a and at the same time the ball holding portion 144b faces the direction communicating with the hitting ball supply port 142a, and a holding position where the ball holding portion 144b faces the partition portion 143a. When the ball feeding member 144 is at the supply position, the game ball B held in the ball holding portion 144b is supplied from the hitting ball supply port 142a to the ball launching device 540, and the game ball B that has entered onto the partition portion 143a from the entrance 141a is blocked from moving toward the ball holding portion 144b (hitting ball supply port 142a) by the blocking portion 144a and remains on the partition portion 143a. On the other hand, when the ball feeding member 144 rotates to the holding position, the ball holding portion 144b faces the partition portion 143a, and the end portion on the paddle portion 144c side of the ball holding portion 144b closes the hitting ball supply port 142a, and only one game ball B on the partition portion 143a is held in the ball holding portion 144b.

[0254] Further, the ball feeding unit 140 includes a ball feeding operating paddle 146 whose tip swings in the vertical direction by driving (energizing) a ball feeding solenoid 145, and a ball feeding crank 147 that rotates around an axis extending in the front-rear direction by the movement of the tip of the ball feeding operating paddle 146 that swings in the vertical direction and rotates the ball feeding member 144 around an axis extending in the vertical direction.

[0255] The ball feeding actuating lever 146 is provided with an iron plate 146a at a position below the ball feeding solenoid 145. The ball feeding actuating lever 146 extends horizontally, and the end portion (right end portion) on the side opposite to the ball feeding crank 147 is rotatably attached to the front cover 141 and the rear cover 142 about an axis extending in the front-rear direction. When the ball feeding solenoid 145 is driven, the iron plate 146a is attracted upward toward the ball feeding solenoid 145 by the generated magnetic force, and the ball feeding actuating lever 146 rotates such that the left end portion side closer to the ball feeding crank 147 moves upward with the right end portion as the center. Then, when the driving of the ball feeding solenoid 145 is released, the magnetic force disappears, and the weight of the iron plate 146a acts, causing the ball feeding actuating lever 146 to rotate such that the left end portion side closer to the ball feeding crank 147 moves downward and returns to the initial state. As a result, the ball feeding actuating lever 146 causes the left end portion (tip) closer to the ball feeding crank 147 to swing in the vertical direction by the ball feeding solenoid 145.

[0256] The ball feeding crank 147 includes an engaging portion 147a that can engage with the tip of the ball feeding actuating lever 146 that moves up and down and extends in the left-right direction, and a shaft portion 147b that is disposed on the side opposite to the side where the engaging portion 147a engages with the ball feeding actuating lever 146 and is pivotally supported between the front cover 141 and the rear cover 142 so as to be rotatable about an axis extending in the front-rear direction. The ball feeding crank 147 further includes a transmission portion 147c that extends upward from the shaft portion 147b and engages with a rod-shaped lever portion 144c (see FIG. 45(b)) that protrudes downward from a position eccentric with respect to the rotation center of the ball feeding member 144.

[0257] By driving the ball feeding solenoid 145 to move the tip (left end) of the ball feeding actuating lever 146 upward, this ball feeding unit 140 can rotate the ball feeding crank 147 about an axis extending in the front-rear direction via the ball feeding actuating lever 146.

[0258] When the ball feeding unit 140 is not driven (normal state) of the ball feeding solenoid 145, the ball feeding operating rod 146 is separated from the lower end of the ball feeding solenoid 145 and the tip is positioned downward, and in this state, the ball feeding member 144 is in the supply position. Further, when the ball feeding solenoid 145 is driven, the ball feeding operating rod 146 is attracted to the lower end of the ball feeding solenoid 145 and the tip (left end) is positioned upward, and the ball feeding member 144 rotates to the holding position. That is, when the ball feeding solenoid 145 is driven (ON state), the ball feeding member 144 receives one game ball B, and when the drive of the ball feeding solenoid 145 is released (OFF state), the game ball B received by the ball feeding member 144 can be sent (supplied) to the ball launching device 540 side. The drive of the ball feeding solenoid 145 in this ball feeding unit 140 is controlled in synchronization with the drive control of the launching solenoid 542 by the launching control unit 633b (see FIG. 126) of the payout control board 633.

[0259] Further, the ball feeding unit 140 is pivotally supported so that a moment is applied to the ball removing member 143 or the weight portion 143d to rotate in the counterclockwise direction when viewed from the front. However, since the operating rod 143c protruding forward of the ball removing member 143 abuts on the upper end of the operation transmission portion 242b of the upper plate ball removing slider 242 that operates by pressing the upper plate ball removing button 222 of the dish unit 200, its rotation is restricted. Therefore, in the normal state, the partition portion 143a of the ball removing member 143 is positioned between the inlet 141a and the ball removing port 141b to partition, and the game ball B does not enter the ball removing port 141b side.

[0260] When the player presses the upper plate ball extraction button 222 of the plate unit 200 downward, the upper plate ball extraction slider 242 slides downward together with the operation transmission part 242b, and as the operation transmission part 242b moves downward, the operation lever 143c also moves relatively downward. When the operation lever 143c moves downward together with the operation transmission part 242b, the ball extraction member 143 rotates counterclockwise in the front view, and the partition part 143a moves from between the entrance 141a and the ball extraction port 141b, and the partition is released. As a result, the game ball B that has entered from the entrance 141a falls toward the ball extraction port 141b side, is discharged from the ball extraction port 141b to the ball extraction guide path 241c of the upper plate ball extraction rear unit 240 in the plate unit 200, and can be discharged (supplied) to the lower plate 202 through the lower plate ball supply port 211c.

[0261] Note that the upper plate ball extraction slider 242 in which the operation transmission part 242b with which the operation lever 143c of the ball extraction member 143 abuts is formed is biased upward by a spring. Therefore, even if the game ball B is vigorously supplied onto the partition part 143a, the impact can be absorbed by the spring via the operation lever 143c, the ball extraction member 143 and the like can be prevented from being damaged, and the game ball B can be prevented from bouncing back at the partition part 143a.

[0262] In addition, the ball feeding unit 140 is formed with a rectangular mounting recess 142b (see FIG. 45(b) etc.) that is recessed forward and upward in the rear view of the hitting ball supply port 142a in the rear cover 142, and an anti-tampering member 148 is mounted in the mounting recess 142b. The anti-tampering member 148 of the ball feeding unit 140 is formed of a hard metal plate such as tool steel or stainless steel, and is detachably mounted from the rear side in the mounting recess 142b of the rear cover 142.

[0263] The anti-tampering member 148 is formed in a rectangular shape with an outer shape extending left and right in a front view, and has an upper piece portion 148a and a lower piece portion 148b that are vertically separated at approximately the center in the vertical direction between a predetermined distance from the right side to the left side, and inclined portions 148c that are each formed in a chamfered C shape on the tip sides (right end side in the front view) of the sides of the upper piece portion 148a and the lower piece portion 148b facing each other. The upper piece portion 148a of the anti-tampering member 148 is bent so that the right end in the front view protrudes rearward with respect to the general surface of the anti-tampering member 148. The lower piece portion 148b extends on the same surface as the general surface of the anti-tampering member 148. Thereby, in a plan view, the upper piece portion 148a and the lower piece portion 148b form a V-shaped groove that widens toward the right.

[0264] The anti-tampering member 148 is attached to the attachment recess 142b of the rear cover 142, so that the V-shaped groove formed by the upper piece portion 148a and the lower piece portion 148b communicates with the inside of the ball supply port 142a.

[0265] According to this anti-tampering member 148, when an illegal game ball B with a string attached is driven into the game area 5a from the upper tray through the ball feeding unit 140 by the ball launcher 540, and an illegal act is performed such as operating the string attached to the illegal game ball B to insert and remove the illegal game ball B from the first start port 2002 or the like, the momentum of the illegal game ball B launched (hit) by the ball launcher 540 causes the string attached to the illegal game ball B to be inserted between the upper piece portion 148a and the lower piece portion 148b, and then cut by the narrowed portion of the V shape formed by the upper piece portion 148a and the lower piece portion 148b, thereby preventing the occurrence of illegal acts using the illegal game ball B with a string attached.

[0266] [3-1j. Far Cover Unit] The fur cover unit 150 of the door frame base unit 100 will be described in detail mainly with reference to FIGS. 46 and 47. FIG. 46(a) is a perspective view of the fur cover unit of the door frame base unit seen from the front, and (b) is a perspective view of the fur cover unit seen from the back. Further, FIG. 47 is a front view of the fur cover unit with the lid member removed. The fur cover unit 150 is attached to the right side in the rear view at the lower part on the rear side of the door frame base 101. The fur cover unit 150 guides the game ball B (fur ball) that has been launched by the ball launching device 540 and has not reached the game area 5a of the game board 5 to the lower tray 202, and also guides the game ball B paid out from the payout device 580 to the upper tray 201 or the lower tray 202. As shown in the figure, the fur cover unit 150 includes a shallow box-shaped unit body 151 attached to the rear side of the door frame base 101 with the front side open, and a flat lid member 152 attached to the front surface of the unit body 151.

[0267] The fur cover unit 150 has a through ball passage 150a that penetrates front and rear at the upper left corner in the front view and communicates the lower normal payout passage 610a of the lower full ball path unit 610 of the main body frame 4 with the upper tray ball supply port 211a of the tray unit 200, and a full ball receiving port 150b that opens rearward on the lower right side in the front view of the through ball passage 150a and can communicate with the lower full ball payout passage 610b of the lower full ball path unit 610 of the main body frame 4.

[0268] Further, the fur cover unit 150 has a fur ball receiving port 150c that opens upward on the right side in the front view of the full ball receiving port 150b and receives the game ball B (fur ball) that has not reached the game area 5a despite being launched by the ball launching device 540 of the main body frame 4, and a ball discharge port 150d that opens forward near the lower right corner in the front view, discharges the game ball B received by the full ball receiving port 150b and the fur ball receiving port 150c forward, and communicates with the lower tray ball supply port 211c of the tray unit 200.

[0269] Furthermore, the fur cover unit 150 includes a storage passage 150e formed between the full ball receiving port 150b, the fur ball receiving port 150c, and the ball discharge port 150d by the unit main body 151 and the lid member 152, and having a size capable of storing a predetermined amount of game balls B.

[0270] The through ball passage 150a is formed across both the unit main body 151 and the lid member 152. The full ball receiving port 150b and the fur ball receiving port 150c are formed in the unit main body 151. The ball discharge port 150d is formed in the lid member 152. The storage passage 150e is formed by the unit main body 151 and the lid member 152.

[0271] Also, the fur cover unit 150 includes a flat movable piece 153 that forms a part of the inner wall of the storage passage 150e and is rotatably attached to the unit main body 151 and the lid member 152 at its lower end, a full detection sensor 154 that detects the rotation of the movable piece 153 in a direction away from the storage passage 150e, and a spring 155 that biases the movable piece 153 toward the storage passage 150e side.

[0272] When the lower plate 202 of the dish unit 200 is filled with game balls B and the game balls B are no longer discharged from the ball discharge port 150d to the lower plate 202 side, the fur cover unit 150 can store a certain number of game balls B in the storage passage 150e. When a certain number of game balls B are stored in the storage passage 150e, the upper end of the movable piece 153 moves in a direction away from the storage passage 150e against the biasing force of the spring 155 due to the weight of the game balls B, and the movable piece 153 rotates. This rotation is detected by the full detection sensor 154. As a result, it can be determined that the lower plate 202 is full of game balls B. Therefore, when the full detection sensor 154 detects a full state, the payout of further game balls B can be stopped, and the fact can be notified to the player, the staff of the game hall, etc., to prompt the elimination of the full state of the lower plate 202.

[0273] Further, the fur cover unit 150 is attached below the through ball passage 150a on the rear side of the unit main body 151, and is provided with a door opening / closing contact portion 150f capable of contacting the operating protrusion 613a of the discharge passage opening / closing door 613 of the lower full ball path unit 610 in the discharge unit 560 (described later) of the main body frame 4 (see FIG. 79). The door opening / closing contact portion 150f is inclined so as to move forward as the rear surface goes downward. When the operating protrusion 613a of the discharge passage opening / closing door 613 contacts the door opening / closing contact portion 150f, the discharge passage opening / closing door 613 can be rotated to open the downstream ends (front openings) of the lower normal discharge passage 610a and the lower full ball discharge passage 610b.

[0274] [3-2. Glass Unit] The glass unit 160 in the door frame 3 will be described in detail mainly with reference to FIGS. 31 and 32 and the like. The glass unit 160 is detachably attached by being inserted into the glass unit attachment portion 101h from the rear so as to close the door window 101a of the door frame base 101 in the door frame base unit 100. When the door frame 3 is closed with respect to the main body frame 4, the glass unit 160 enables the game area 5a of the game board 5 attached to the main body frame 4 to be visible from the player side (front), and closes the front of the game area 5a.

[0275] The glass unit 160 includes a frame-shaped glass frame 161 that is larger than the inner peripheral shape of the door window 101a of the door frame base 101 and can be attached to the glass unit attachment portion 101h, two transparent glass plates 162 that close the inside of the glass frame 161 and have an outer periphery attached to the glass frame 161, and a pair of glass unit attachment members 163 that are rotatably attached to the rear side of the door frame base 101 in the door frame base unit 100 and attach the glass frame 161 to the door frame base 101.

[0276] The glass frame 161 has a pair of mounting pieces 161a that extend outward in a flat plate shape from positions below the upper left and right corners when viewed from the front, and a strip-shaped locking piece 161b that protrudes downward from the lower end and extends along the lower side. The mounting piece 161a of the glass frame 161 is capable of abutting against the protruding portion 163b of the glass unit mounting member 163. The locking piece 161b can be inserted into the space between the door frame base 101 and the rear flange portion 117c of the intermediate reinforcing frame 117 of the door frame reinforcing unit 110 so as to be placed on the upper flange portion 117b of the intermediate reinforcing frame 117 (see FIGS. 37 and 85). In the present embodiment, the rear surface of the locking piece 161b abuts against the front surface of the rear flange portion 117c. The two glass plates 162 are respectively attached to the front end side and the rear end side of the glass frame 161, and are spaced apart from each other in the front-rear direction so that a space is formed therebetween.

[0277] The glass unit mounting member 163 has a disk-shaped base portion 163a that is rotatably mounted around an axis extending in the front-rear direction on the rear side of the door frame base 101, and a protruding portion 163b that protrudes in a rod shape in a direction perpendicular to the rotation axis from the base portion 163a. The glass unit mounting member 163 is rotatably mounted respectively outside the upper two corners among the four corners of the door window 101a on the rear surface of the door frame base 101.

[0278] To attach the glass unit 160 to the door frame base 101, first, rotate the glass unit attachment member 163 attached to the door frame base 101 so that the protruding portion 163b is positioned above the base portion 163a. Then, from the rear side of the door frame base 101, insert the locking piece 161b of the glass frame 161 of the glass unit 160 upward into the gap between the door frame base 101 and the rear flange portion 117c of the intermediate reinforcing frame 117 of the door frame reinforcing unit 110 and place it on the upper flange portion 117b. After that, bring the front end of the glass frame 161 into contact with the rear surface of the glass unit attachment portion 101h of the door frame base 101. Subsequently, rotate the glass unit attachment member 163 so that the protruding portion 163b is positioned below the base portion 163a and bring the protruding portion 163b into contact with the rear surface of the attachment piece 161a of the glass frame 161. Thereby, the glass unit 160 is attached to the door frame base 101.

[0279] When removing the glass unit 160 from the door frame base 101, it can be removed by the reverse procedure of the above. Thereby, the glass unit 160 is detachable from the door frame base 101 (door frame base unit 100).

[0280] Note that in the glass unit 160, when the protruding portion 163b of the glass unit attachment member 163 is in the rotational position where it is located below the base portion 163a, the protruding portion 163b restricts the backward movement of the glass frame 161. Therefore, even if vibrations or the like act on the glass unit attachment member 163, the protruding portion 163b does not rotate to a position where it is above the base portion 163a. Accordingly, the restriction on the backward movement of the glass frame 161 is not naturally released, and the glass unit 160 does not naturally come off the door frame base 101.

[0281] [3-3. Anti-theft Cover] Regarding the security cover 170 in the door frame 3, it will be described in detail mainly with reference to FIGS. 31 and 32 and the like. The security cover 170 is attached to the rear side of the door frame base unit 100 so as to cover the lower rear part of the glass unit 160, and is formed of a transparent synthetic resin. The security cover 170 includes a flat main body portion 171 whose outer periphery is formed in a predetermined shape, a flat rear protruding piece 172 that protrudes backward along the outer peripheral edge of the main body portion 171, and a pair of locking pieces 173 that are spaced apart left and right and protrude forward from the main body portion 171 and can be locked to the rear side of the door frame base 101.

[0282] The main body portion 171 of the security cover 170 is formed such that its lower end protrudes downward more than the lower end of the glass unit 160 when attached to the door frame base unit 100. Also, the upper end of the main body portion 171 is formed in a shape along the lower end of the game area 5a in the game board 5 when assembled to the pachinko machine 1. Specifically, the upper end of the main body portion 171 is formed in a shape along a part of the inner rail 1002 of the front component 1000 described later, the out guide portion 1003, a part of the lower right rail 1004, and the right rail 1005, and is formed so as not to protrude into the game area 5a when assembled to the pachinko machine 1.

[0283] The rear protruding piece 172 is formed over substantially the entire circumference of the outer peripheral edge of the main body portion 171. Therefore, the security cover 170 is formed in a shallow box shape that is open to the rear by the main body portion 171 and the rear protruding piece 172, and has high strength and rigidity. Also, the rear protruding piece 172 protrudes backward from a part of the rear surface of the main body portion 171 that is different from the outer peripheral edge of the main body portion 171. The rear protruding piece 172 that protrudes backward from a part of the rear surface of the main body portion 171 is formed to be along a part of the outer rail 1001 in the front component 1000 of the game board 5 when assembled to the pachinko machine 1.

[0284] Note that the rear protruding piece 172 is not formed at a position between the outer rail 1001 and the inner rail 1002 on the game board 5 when the pachinko machine 1 is assembled. Thereby, the game ball B (the game ball B launched by the ball launching device 540) passing between the outer rail 1001 and the inner rail 1002 does not contact the rear protruding piece 172 of the security cover 170, and does not inhibit the entry of the game ball B into the game area 5a.

[0285] The pair of locking pieces 173 are elastically locked to the rear side of the door frame base unit 100 (the speaker duct 103 and the cable cover 109). Thereby, the security cover 170 can be easily attached to and detached from the door frame base unit 100.

[0286] When the security cover 170 is assembled to the pachinko machine 1, the front surface of the main body 171 contacts the rear surface (the rear end of the glass frame 161) of the glass unit 160, and the rear protruding piece 172 excluding the part protruding rearward from the lower side of the main body 171 is inserted into the security recess 1009 of the front component 1000. Further, the security cover 170 is in a state of protruding rearward from the front surface of the front component 1000 so that the rear protruding piece 172 protruding rearward from the lower side of the main body 171 contacts the lower surface of the front component 1000. Thereby, since the space between the security cover 170 and the game board 5 (the front component 1000) is in a complex bent state by the rear protruding piece 172 of the security cover 170 and the security recess 1009 of the front component 1000, even if an illegal tool such as a piano wire tries to enter the game area 5a through the space between the security cover 170 and the front component 1000 from below the front surface of the game board 5, it will be blocked by the rear protruding piece 172 and the security recess 1009, and the entry of illegal tools into the game area 5a can be prevented.

[0287] [3-4a. Handle Unit] Next, the handle unit 180 in the door frame 3 will be described in detail with reference to FIGS. 48 to 52 and the like. FIG. 48 is an exploded perspective view of the handle unit, the plate unit, and the effect operation unit in the door frame as viewed from the front, and FIG. 49 is an exploded perspective view of the handle unit, the plate unit, and the effect operation unit in the door frame as viewed from the rear. FIG. 50 is an exploded perspective view of the handle unit in the door frame as viewed from the front after being disassembled, and FIG. 51 is an exploded perspective view of the handle unit in the door frame as viewed from the rear after being disassembled. FIG. 52(a) is an explanatory view showing the relationship between the handle base, the handle, the handle return spring, and the handle touch sensor in the handle unit in a perspective view, and (b) is an explanatory view showing (a) in a perspective view after being disassembled. FIG. 53 is an explanatory view showing the relationship between the handle base, the handle, the handle return spring, the handle touch sensor, and the inner base in the handle unit in a perspective view as viewed from the rear. In FIG. 53, the position of the first attachment portion 190a of the handle return spring 190 is changed for easy understanding.

[0288] The handle unit 180 of the present embodiment is attached to the door frame base unit 100 from the front inside a cylindrical handle cover unit 290, and by being operated by a player, the game ball B in the upper plate 201 can be driven into the game area 5a of the game board 5.

[0289] The handle unit 180 includes a handle base 181 whose rear end is attached to the handle attachment seat surface of the door frame base 101, a handle 197 rotatably attached to the front end of the handle base 181, a disk-shaped cover pedestal 183 attached to the handle base 181 so as to cover the center of the front end side of the handle 197, a handle decorative substrate 184 attached to the front side of the cover pedestal 183 and having a plurality of LEDs 184a mounted on the front surface thereof, and a handle front lens 185 attached to the cover pedestal 183 so as to cover the front side of the handle decorative substrate 184.

[0290] Further, the handle unit 180 includes an inner base 186 attached to the front surface of the handle base 181 on the rear side of the handle 197, a shaft member 187 having a drive gear portion 187a on the outer periphery thereof, with the handle 197 attached to the front end and rotatably attached by the inner base 186 and the handle base 181, a transmission gear 188 meshing with the drive gear portion 187a of the shaft member 187, and a handle rotation detection sensor 189 having a detection shaft 189a that rotates integrally with the transmission gear 188 and is sandwiched between the handle base 181 and the inner base 186.

[0291] Furthermore, the handle unit 180 includes a handle return spring 190 having one end attached to the handle base 181 and the other end attached to the handle 197, biasing the handle 197 to return to the initial rotation position (the rotation end in the counterclockwise direction in a front view), and an auxiliary spring 191 having one end attached to the inner base 186 and the other end attached to the transmission gear 188, biasing the detection shaft 189a of the handle rotation detection sensor 189 in the clockwise direction in a front view via the transmission gear 188.

[0292] The handle unit 180 also includes a handle touch sensor 192 attached to the handle base 181 behind the inner base 186, a single-shot button 193 having a tip protruding outward from the left side in a front view of the outer peripheral surface of the front end of the handle base 181 and rotatably attached around a shaft extending back and forth to the handle base 181 behind the inner base 186, and a single-shot button operation sensor 194 attached to the handle base 181 for detecting a pressing operation of the single-shot button 193.

[0293] The handle base 181 of the handle unit 180 includes a cylindrical base portion 181a extending in the front-rear direction, a disc-shaped front end portion 181b protruding radially from the front end of the base portion 181a, and groove portions 181c that are recessed from the outer peripheral surface of the cylindrical base portion 181a, extend in the axial direction, and are formed in three at unequal intervals in the circumferential direction. The outer diameter of the base portion 181a of the handle base 181 is formed slightly smaller than the inner diameter of the rear cylindrical portion of the handle cover base 291 in the handle cover unit 290. Further, the three groove portions 181c are formed at positions corresponding to the three ridges of the handle cover base 291. Therefore, with the three groove portions 181c aligned with the three ridges, the base portion 181a can be inserted into the rear cylindrical portion of the handle cover base 291, and by inserting the ridges into the three groove portions 181c respectively, the handle base 181 is in a state where it cannot rotate relative to the handle cover base 291.

[0294] In addition, the handle base 181 includes a sensor housing recess 181d for housing a handle touch sensor 192 therein from the front, a tab contact portion 181e against which a tab-shaped terminal 192a of the handle touch sensor 192 abuts, and a mounting hole 181f provided in the tab contact portion 181e (see FIG. 52). The handle touch sensor 192 is housed in the sensor housing recess 181d, and the tab-shaped terminal 192a of the handle touch sensor 192 is brought into contact with the tab contact portion 181e. Then, the rear portion of the inner base 186 is inserted into the handle base 181 from the front, and a mounting piece 186a of the inner base 186 (see FIG. 53) is positioned in front of the tab-shaped terminal 192a. Then, by screwing and tightening a mounting screw (not shown) into the mounting hole 181f from the front of the mounting piece 186a of the inner base 186, the handle touch sensor 192 can be attached to the handle base 181 together with the inner base 186. At this time, by screwing the mounting screw so as to sandwich a U-shaped second mounting portion 190b provided on the rear end side of the handle return spring 190 between the mounting piece 186a of the inner base 186 and the tab-shaped terminal 192a of the handle touch sensor 192, the rear end side of the handle return spring 190 can be attached to the handle base 181, and the handle return spring 190 and the handle touch sensor 192 can be electrically connected. The portion of the tab contact portion 181e in the handle base 181 can face forward through a slit 197e (described later) in the handle 197, and a driver as a tool can be approached from the front through the slit 197e.

[0295] The handle 197 is provided with a plating layer having conductivity on its surface. The handle 197 includes four first protrusions 197a, second protrusions 197b, third protrusions 197c, and fourth protrusions 197d that protrude outward away from the outer peripheral surface in the circumferential direction, two slits 197e that extend in an arc shape centered on the rotation axis (shaft member 187) and penetrate in the front-rear direction, a spring attachment piece 197f provided at one end side of one slit 197e and facing forward at a portion recessed toward the center side of the handle 197, and an attachment hole 197g that penetrates the spring attachment piece 197f in the front-rear direction.

[0296] With the annular first attachment portion 190a provided at the front end of the handle return spring 190 being abutted against the upper surface of the spring attachment piece 197f in the handle 197, by screwing and tightening a mounting screw (not shown) into the attachment hole 197g from the front, the front end side of the handle return spring 190 can be mounted from the front, and the plating layer on the surface of the handle 197 and the handle return spring 190 can be electrically connected. Thereby, the handle touch sensor 192 and the handle 197 are electrically connected via the metal handle return spring 190, and it becomes possible to detect contact of the handle 197 by a player.

[0297] The four first protrusions 197a, second protrusions 197b, third protrusions 197c, and fourth protrusions 197d in the handle 197 are provided in order in the counterclockwise direction in a front view.

[0298] As described above, according to the handle unit 180 of the present embodiment, since both ends of the metal handle return spring 190 that electrically connects the handle touch sensor 192 and the handle 197 are respectively attached by mounting screws, compared with the case where both ends of the handle return spring 190 are merely in contact, it is possible to surely make an electrical connection and surely prevent a contact failure (detection failure of the handle touch sensor 192). Therefore, in the game hall where the pachinko machine 1 is installed, chemicals such as alcohol and sodium hypochlorite used during cleaning do not enter the handle unit 180, or gases or the like are generated from the chemicals and adhere to the handle return spring 190 or the like, causing corrosion or oxidation of the surface. However, no contact failure will occur, and the handle touch sensor 192 can surely detect the contact of the player.

[0299] Further, in the handle unit 180 of the present embodiment, since a driver for turning a mounting screw can be approached from the front through the slit 197e of the handle 197 with respect to the first attachment portion 190a and the second attachment portion 190b which are both ends of the handle return spring 190, the handle unit 180 can be easily assembled and maintenance is easy.

[0300] This handle unit 180 is attached to the handle mounting seat surface of the door frame base 101 via the handle cover unit 290. The handle mounting seat surface of this door frame base 101 is inclined so that the right end side is located behind the left end side in a plan view and faces the outside (open side). Therefore, the handle unit 180 is also inclined outward in a plan view (in other words, the tip portion thereof is inclined so as to face the outside of the pachinko machine 1 with respect to the line orthogonal to the front surface of the pachinko machine 1.) and is attached and fixed to the door frame 3. Thereby, it is easy for the player to grip the handle 197 of the handle unit 180, and a rotation operation can be performed without a sense of discomfort.

[0301] [3-4a-1. Modification example of handle unit] Next, a modified example of the handle unit will be described. Note that only one of the following plurality of modified examples may be used, or a plurality of modified examples may be appropriately combined and used together with the above-described embodiment.

[0302] (Modified Example 1) In the above embodiment, the tab-shaped terminal 192a of the handle touch sensor 192 and the second attachment portion 190b of the handle return spring 190 are shown to be attached together with a mounting screw, but the present invention is not limited thereto. For example, a protrusion may be provided on the handle 197, and the shape of the front end side (first attachment portion 190a) of the handle return spring 190 may be made to follow a part of the outer periphery of the protrusion of the handle 197 so that the front end of the handle return spring 190 is locked to the protrusion. As a result, the front end side of the handle return spring 190 comes into line contact with the protrusion, and the occurrence of poor contact can be prevented by increasing the contact portion as compared with point contact. In this case, it is desirable to provide the protrusion of the handle 197 at a location where chemicals such as alcohol or sodium hypochlorite used for cleaning are less likely to be applied. Alternatively, a cover may be provided at the location so that chemicals such as alcohol do not adhere thereto.

[0303] (Modified Example 2) Also, for example, the configuration as shown in FIG. 54 may be used. FIG. 54 is an explanatory diagram shown as a perspective view seen from the rear of the relationship between the handle base, the handle, the handle return spring, the handle touch sensor, and the inner base, which is a modified example of the handle unit. In this modified example, the handle 197 is composed of a main body portion 197A and an annular ring portion 197B, and the ring portion 197B is formed of metal or resin having a plating layer on its surface. The ring portion 197B of the handle 197 is provided such that the outer peripheral surface is exposed to the outside at the rear end of the handle 197 (the front end of the handle base 181). Then, the ring portion 197B and the handle touch sensor 192 may be electrically connected by an electric wire 198.

[0304] Specifically, one round terminal 198a of the electric wire 198 provided with round terminals 198a at both ends is sandwiched between the attachment piece 186a of the inner base 186 and the tab-shaped terminal 192a of the handle touch sensor 192, and is screwed together with them using a mounting screw. The other round terminal 198a of the electric wire 198 is screwed to the attachment portion 197h of the ring portion 197B in the handle 197. As a result, when the player grips the handle 197, their finger will contact the ring portion 197B, and the contact can be detected via the ring portion 197B and the electric wire 198. Therefore, similar to the above, poor contact (detection failure of the handle touch sensor 192) can be reliably prevented. Thus, in the game hall where the pachinko machine 1 is installed, even if chemical solutions such as alcohol or sodium hypochlorite are used during cleaning, poor contact will not occur, and the handle touch sensor 192 can reliably detect the contact of the player.

[0305] Note that the ring portion 197B of the handle 197 may be fixed to the main body portion 197A and provided so as to be integrally rotatable, or may be guided by the main body portion 197A or the handle base 181 and provided so as to be relatively rotatable. Also, in the above, an annular ring portion 197B was shown, but a non-annular ring portion 197B that does not make a full circle, such as a C shape, may also be used.

[0306] Also, in the above, the handle 197 is shown as being composed of the main body portion 197A and the ring portion 197B, but it is not limited to this, and the ring portion 197B may be an independent structure separate from the handle 197.

[0307] (Modification Example 3) Also, for example, the handle touch sensor 192 can be provided at another position, and using a wire 198 provided with round terminals 198a at both ends, one round terminal 198a is screwed together with the tab terminal 192a using a mounting screw, and the other round terminal 198a is screwed together with the second mounting portion 190b of the handle return spring 190 using a mounting screw. By doing so as well, similar to the above, it is possible to reliably prevent poor contact (detection failure of the handle touch sensor 192). Therefore, even if chemical solutions such as alcohol or sodium hypochlorite are used during cleaning in the game hall where the pachinko machine 1 is installed, poor contact will not occur, and the handle touch sensor 192 can reliably detect the contact of the player. In this case, the front end side (first mounting portion 190a) of the handle return spring 190 may be attached to the handle 197 using a mounting screw, or may be locked to a protrusion provided on the handle 197.

[0308] (Modification Example 4) Also, for example, a mounting hole is provided on the back surface of the handle 197, and one round terminal 198a of the wire 198 provided with round terminals 198a at both ends is screwed together with the tab terminal 192a of the handle touch sensor 192 using a mounting screw, and the other round terminal 198a is screwed using a mounting screw that is screwed into the mounting hole of the handle 197. At this time, the length of the wire 198 is set to a length that allows the handle 197 to rotate. As the portion of the handle 197 where the round terminal 198a of the wire 198 is screwed, for example, when the handle 197 has a ring portion 197B as shown in FIG. 54, the ring portion 197B is provided so as to rotate integrally with the main body portion 197A, and the round terminal 198a may be screwed to the mounting portion 197h of the ring portion 197B. By doing so as well, similar to the above, it is possible to reliably prevent poor contact (detection failure of the handle touch sensor 192). Therefore, even if chemical solutions such as alcohol or sodium hypochlorite are used during cleaning in the game hall where the pachinko machine 1 is installed, poor contact will not occur, and the handle touch sensor 192 can reliably detect the contact of the player.

[0309] (Other Modification Examples) In the above description, it is shown that a screw is used to fasten to the plating layer provided on the handle 197, but the present invention is not limited thereto. For example, when a metal part is provided on the handle 197, it may be screwed to the metal part so as to be electrically connected to the handle touch sensor 192. As this metal part, for example, the above-described ring part 197B may be made of metal.

[0310] Also, in the above description, the handle touch sensor 192 is shown as having the tab-shaped terminal 192a, but the present invention is not limited thereto, and the handle touch sensor may have a connector. In this case, the tip side of the electric wire connected to the connector may be directly or electrically connected to the handle 197 via the handle return spring 190.

[0311] [3-4a-2. Parentheses] The above-described handle unit 180 has the following technical features. (Background of Technical Features) In a pachinko machine as a gaming machine, there are provided a handle that a player operates to launch a game ball into a game area, and a touch sensor for detecting that the player is touching the handle (for example, Patent Document: Japanese Patent Application Laid-Open No. 2020-137794). In a conventional gaming machine as described in the above patent document, the touch sensor and the handle are electrically connected via a spring for returning the handle to its original position to detect contact with the handle by the player. In this type of conventional gaming machine, in the spring for returning the handle, the end on the touch sensor side and the end on the handle side are brought into contact with each other using the biasing force of the spring.

[0312] By the way, when cleaning and disinfecting gaming machines in a game hall where gaming machines are installed, chemical solutions such as alcohol or sodium hypochlorite may be used. And if the chemical solution used for cleaning or the like enters the handle or gas is generated and adheres to a spring or the like, the surface of the spring or the like may corrode or oxidize, resulting in an electrical contact failure. Due to such a contact failure, the firing of the game balls may become unstable or the game balls may not be fired, which may reduce the interest of the players.

[0313] Therefore, in view of the above situation, the following means aims to provide a gaming machine capable of reliably detecting the contact of the handle by the player.

[0314] (Means for Solving Technical Features) Means 1: In a gaming machine, 「A gaming machine equipped with a handle unit for firing game balls into the game area, The handle unit includes A rotatable handle, A handle base that rotatably supports the handle, A touch sensor provided on the handle base, One end side of the electrode tab of the touch sensor, or the tip of the electric wire connected to the electrode tab or the connector of the touch sensor, is screwed, and the other end side is in contact with the plated portion or the metal portion of the handle, and a linear metal wire body Characterized by comprising」

[0315] Here, examples of the "wire body" include "spring", "electric wire", etc.

[0316] According to the configuration of means 1, a gaming machine includes a handle unit for launching a game ball into a game area. The handle unit includes a rotatable handle, a handle base that rotatably supports the handle, a touch sensor provided on the handle base, an electrode tab of the touch sensor, or the tip of an electric wire connected to the electrode tab or the connector of the touch sensor. One end side is screwed, and the other end side is in contact with the plated portion or the metal portion of the handle, and a linear metal wire body is provided. (Refer to the description in the chapter of [3-4a. Handle Unit] and FIGS. 50 to 54, etc. in [Embodiments of the Invention])

[0317] In this configuration, in the handle unit for launching a game ball into a game area, one end side of a metal wire body whose other end side is in contact with the plated portion or the metal portion of the handle is screwed together with the electrode tab of a touch sensor provided on the handle base, or the tip of an electric wire connected to the electrode tab or the connector of the touch sensor. That is, one end side of the wire body is screwed to the electrode tab of the touch sensor, or the tip of the electric wire that is electrically connected to the touch sensor via the electrode tab or the connector. Thereby, compared with the case where one end side of the wire body is simply brought into contact without screwing, when chemicals such as alcohol or sodium hypochlorite used during cleaning of the gaming machine enter the handle, or gases are generated and adhere to springs or the like, even if the surface corrodes or oxidizes, no contact failure will occur, and the touch sensor can surely detect the player's contact with the handle via the wire body. Therefore, it is possible to provide a gaming machine that can prevent the launch of the game ball from becoming unstable or the game ball from not being able to be launched due to a detection failure of the touch sensor, allowing the player to enjoy the game in a good state and suppressing a decrease in the player's interest.

[0318] In addition, when the electrode tab of the touch sensor is screwed, it is desirable to attach the touch sensor to the handle base. Thereby, the attachment of one end side of the linear body and the attachment of the touch sensor can be performed simultaneously, and the labor required for assembly and disassembly can be reduced.

[0319] Further, the other end side of the linear body may be locked to a protruding portion protruding from the handle. Thereby, since the other end side of the linear body is locked to the protruding portion of the handle and electrically connected, the labor (man-hours) required for the assembly and disassembly of the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0320] Furthermore, the other end side of the linear body may be screwed to the handle. Thereby, since the other end side of the linear body is also screwed to the handle, it is possible to make it difficult for a poor contact to occur not only on one end side but also on the other end side. Therefore, even if the linear body or the like is corroded or oxidized by a chemical solution such as alcohol or sodium hypochlorite during the cleaning of the gaming machine, a poor contact does not occur, and the touch sensor can surely detect the contact of the player with the handle via the linear body.

[0321] Also, as described above, when the other end side of the linear body is also screwed, it is desirable to be able to approach a tool such as a driver from the same direction with respect to the respective screws (mounting screws) on one end side and the other end side of the linear body. Thereby, since the linear body can be screwed from the same direction at both ends, the labor required for assembling the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0322] Also, it is desirable that the linear body be a spring that biases the handle around the axis. As a result, since the linear body that electrically connects the handle and the touch sensor is used as the spring that biases the handle, compared with the case where the linear body is a member separate from the spring (for example, an electric wire), the number of parts of the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0323] Means 2: In the configuration of Means 1, "The other end side of the linear body is locked to a protrusion protruding from the handle" is characterized by being such.

[0324] Here, examples of the "protrusion" include "one integrally formed with the handle", "one insert-molded with respect to the handle (for example, a metal pin)", "one attached to the handle separately from the handle (for example, a metal pin, a screw, etc.)", and the like.

[0325] According to the configuration of Means 2, the other end side of the linear body is locked to a protrusion protruding from the handle. (Refer to the chapter of [3-4a. Handle unit] in [Embodiment for Carrying Out the Invention])

[0326] As a result, since the other end side of the linear body is electrically connected by being locked to the protrusion of the handle, the labor (man-hours) required for assembling and disassembling the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0327] Note that after locking the other end side of the linear body to the protrusion of the handle, it may be screwed. As a result, in the linear body, it is possible to make it difficult for a contact failure to occur not only on one end side but also on the other end side, and it is possible to surely detect the contact of the handle by the player by the touch sensor.

[0328] Means 3: In the configuration of Means 1 or Means 2, "The other end side of the linear body is screwed to the handle." It is characterized by being such.

[0329] According to the configuration of means 3, the other end side of the linear body is screwed to the handle. (Refer to the description of the handle return spring 190 and FIG. 52, etc. in [Mode for Carrying Out the Invention])

[0330] As a result, since the other end side of the linear body is also screwed to the handle, it is possible to make it difficult for poor contact to occur not only on one end side but also on the other end side. Therefore, when cleaning the gaming machine, even if the linear body and the like are corroded or oxidized by a chemical solution such as alcohol or sodium hypochlorite, poor contact will not occur, and it is possible to surely detect the contact of the player with the handle by the touch sensor via the linear body.

[0331] In addition, since the one end side and the other end side of the linear body are each screwed, it is desirable to be able to approach a tool such as a driver from the same direction for each screw (mounting screw). As a result, since the both ends of the linear body can be screwed from the same direction, the labor involved in assembling the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0332] Means 4: In any one of the configurations from means 1 to means 3, "The linear body is a spring that biases the handle around the axis." It is characterized by being such.

[0333] According to the configuration of means 4, the linear body is made into a spring that biases the handle around the axis. (Refer to the description of the handle return spring 190 in [Mode for Carrying Out the Invention])

[0334] As a result, since the linear body that electrically connects the handle and the touch sensor is used as the spring that biases the handle, compared with the case where the linear body is a member different from the spring (for example, an electric wire), the number of parts of the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0335] Thus, according to the above solution means, it is possible to provide a gaming machine capable of reliably detecting contact with the handle by the player.

[0336] (Relationship between the solution means of the technical features and the embodiments) The handle unit 180 in the door frame 3 of the present embodiment corresponds to the handle unit of the above solution means, the handle base 181 of the handle unit 180 in the present embodiment corresponds to the handle base of the above solution means, the handle return spring 190 of the handle unit 180 in the present embodiment corresponds to the linear body and the spring of the above solution means, the handle touch sensor 192 of the handle unit 180 in the present embodiment corresponds to the touch sensor of the above solution means, the tab-shaped terminal 192a of the handle touch sensor 192 in the present embodiment corresponds to the electrode tab of the above solution means, and the handle 197 of the handle unit 180 in the present embodiment corresponds to the handle of the above solution means, respectively.

[0337] (Characteristic effects of the present embodiment) According to the pachinko machine 1 of this embodiment, in the handle unit 180 for firing the game ball B in the door frame 3 into the game area 5a, one end side (second attachment portion 190b side) of the handle return spring 190, which is a metal linear body whose other end side (first attachment portion 190a side) is in contact with the plated portion of the handle 197, is screwed together with the tab-shaped terminal 192a of the handle touch sensor 192 provided on the handle base 181. That is, one end side of the handle return spring 190 is screwed to the tab-shaped terminal 192a of the handle touch sensor 192. Thereby, compared with the case where one end side of the handle return spring 190 is merely brought into contact without being screwed, even if chemicals such as alcohol or sodium hypochlorite used during cleaning of the pachinko machine 1 enter the handle unit 180, or gas or the like is generated and adheres to the spring or the like, causing the surface to corrode or oxidize, no contact failure will occur, and the handle touch sensor 192 can surely detect the contact of the player with the handle 197 via the handle return spring 190. Therefore, the firing of the game ball B will not become unstable or impossible to fire due to a detection failure of the handle touch sensor 192, and it is possible to provide the pachinko machine 1 that can allow the player to enjoy the game in a good state and suppress a decrease in the player's interest.

[0338] Also, when the tab-shaped terminal 192a of the handle touch sensor 192 is screwed, since the handle touch sensor 192 is attached to the handle base 181, the attachment of one end side (second attachment portion 190b side) of the handle return spring 190 and the attachment of the handle touch sensor 192 can be performed simultaneously, reducing the labor required for assembly and disassembly.

[0339] Furthermore, since the other end side (the first attachment portion 190a side) of the handle return spring 190 is screwed to the handle 197, it is possible to make it difficult for a poor contact to occur not only at the one end side (the second attachment portion 190b side) but also at the other end side (the first attachment portion 190a). Therefore, even if the handle return spring 190 or the like is corroded or oxidized by a chemical solution such as alcohol or sodium hypochlorite during the cleaning of the pachinko machine 1, a poor contact does not occur, and the handle touch sensor 192 can surely detect the contact of the player with the handle 197 via the handle return spring 190.

[0340] Also, at one end side (the second attachment portion 190b side) and the other end side (the first attachment portion 190a side) of the handle return spring 190, tools such as a driver can be approached from the same direction (here, the front) with respect to the respective screws (attachment screws), and since the handle return spring 190 can be screwed from the same direction at both ends, the labor required for assembling the handle unit 180 can be reduced, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0341] Also, since the linear body that electrically connects the handle 197 and the handle touch sensor 192 is the handle return spring 190 that biases the handle 197, the number of parts of the handle unit 180 can be reduced compared to the case where the linear body is a separate member (for example, an electric wire) from the handle return spring 190, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0342] Note that the other end side (the first attachment portion 190a side) of the handle return spring 190 may be locked to a protruding portion that protrudes rearward from the handle 197. Thereby, since the other end side of the handle return spring 190 is electrically connected by being locked to the protruding portion of the handle 197, the labor (man-hours) required for assembling and disassembling the handle unit 180 can be reduced, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0343] [3-4b. Handle Cover Unit] The handle cover unit 290 in the door frame 3 will be described in detail mainly with reference to FIGS. 48 and 49 and the like. The handle cover unit 290 includes a handle cover base 291 that covers the outer periphery on the rear side of the handle 197 in the handle unit 180 and has its rear end attached to the handle mounting seat surface of the door frame base 101, and a handle cover 295 that covers the outer periphery with a space therebetween and has its rear end attached to the dish unit main body 252 of the dish unit 200.

[0344] The handle cover base 291 has a cylindrical rear cylinder portion that extends back and forth with an inner diameter into which the base portion 181a of the handle base 181 can be inserted, and a plurality (here, three) of ridges that project inward from the inner periphery of the rear cylinder portion, extend back and forth, and are provided at positions corresponding to the groove portions 181c of the handle base 181 in the circumferential direction.

[0345] The rear cylinder portion has its rear end attached to the handle mounting seat surface of the door frame base 101. This rear cylinder portion is formed to have the same length as the base portion 181a of the handle base 181, and the base portion 181a of the handle base 181 is inserted therein. The three ridges correspond to the three groove portions 181c of the handle base 181, and by being inserted into the groove portions 181c, the handle base 181 can be made non-rotatable relative to each other.

[0346] The handle cover 295 has a front hole 295a with a larger diameter than the handle 197 at the front end, and is formed in a cylindrical shape like a spindle base (kamakura type, or bowl type, etc.) that bulges toward the rear, and a plurality (here, four) of notch openings 295b that are notched from the rear end toward the front are provided in the circumferential direction. The rear end of the handle cover 295 is attached to the dish unit main body 252 of the dish unit 200.

[0347] The handle cover unit 290 of the present embodiment can discharge liquids such as drinks and game balls B into the cylinder through the lower notch opening 295b even if they enter the cylinder, and discharge them downward of the handle cover unit 290.

[0348] In addition, the lower notch opening 295b of the handle cover 295 is provided on the extension line in the inclination direction of the blade portion 46b of the grill member 46 in the outer frame lower assembly 40 of the outer frame 2. Thereby, the wind (wind pressure) discharged obliquely upward and forward from the grill member 46 through the blade portion 46b due to the vibration of the main body frame speaker 622 can enter the cylinder through the notch opening 295b. Therefore, when the player inserts a finger into the cylinder of the handle cover 295 and rotates the handle 197 (game ball B driving device), by vibrating the main body frame speaker 622 and sending wind into the front cylinder portion 291a, the player can be surprised and a novel effect can be achieved. That is, since a stimulus by sound pressure can be applied to the finger of the player operating the handle 197, the player can be surprised, made to anticipate the arrival of a chance, or made to change the operation amount of the handle operation, etc., making the player enjoy the game and making it difficult for the player to get bored, and suppressing a decrease in interest in the game.

[0349] Furthermore, since the sound pressure (sound wind) from the main body frame speaker 622 can be supplied into the handle cover unit 290 through the notch opening 295b, the inside of the handle cover unit 290 can be cooled, and by making the environment around the fingers of the player operating the handle 197 comfortable, the stress on the player can be alleviated and a decrease in interest in the game can be suppressed.

[0350] Also, as described above, with respect to the fingers of a player who is operating the handle 197 with a finger inserted into the handle cover unit 290, the sound pressure (sound wind) emitted forward from the port member 47 provided on the outer frame lower assembly 40 of the outer frame 2, which is different from the door frame 3 where the handle 197 and the handle cover unit 290 are provided, is guided by the plurality of blade portions 46b of the grill member 46 to apply a stimulus. Therefore, compared with the case where a vibration device is provided on the handle 197, various sensors provided on the handle 197 (handle rotation detection sensor 189, handle touch sensor 192, single-shot button operation sensor 194, etc.) and the bearing mechanism are not damaged, and it is possible to make the handle unit 180 difficult to be damaged, avoiding giving discomfort to the player due to the damage of the handle unit 180, and suppressing a decrease in the player's interest in the game.

[0351] Furthermore, since the handle cover 295 has the notch opening 295b, when opening the door frame 3 or the main body frame 4, a finger can be hooked on the right notch opening 295b and pulled, and it can be used as a handle when opening the door frame 3 or the like.

[0352] Also, since the handle cover 295 has the notch opening 295b, by hooking a finger on the handle 197 and the notch opening 295b and grasping them, the rotational position of the handle 197 can be easily fixed, and the game ball B can be continuously driven into the game area 5a with a certain strength without continuously twisting the hand. In this way, since the handle 197 can be rotated in various ways to drive the game ball B, it is possible to provide the pachinko machine 1 that can select a driving operation suitable for the player.

[0353] In addition, a handle 197 is provided at the lower right corner of the door frame 3 on the side opposite to the hinge side, and a notch opening 295b is provided at a portion facing the right side of the outer peripheral surface of the handle cover 295 of the handle cover unit 290. Therefore, the notch opening 295b can be used as a handle when opening and closing the door frame 3. Accordingly, there is no need to provide a handle that deteriorates the appearance of the door frame 3, and the appearance of the door frame 3 can be improved.

[0354] [3-5. Overall Structure of Dish Unit] Regarding the dish unit 200 in the door frame 3, it will be described in detail mainly with reference to FIGS. 48 and 49.

The upper dish 201 is formed by a dish unit base 211 and an upper dish main body 212, and is formed in a container shape that bulges forward more on the left side than the center of the left and right sides when viewed from the front and is open upward. The upper dish 201 (upper dish main body 212) bulges most forward at about 1 / 3 of the part from the left end to the right with respect to the width of the door frame 3 in the left - right direction. From the most bulging part, as it goes to the right when viewed from the front, the front end of the upper dish 201 retreats backward, and has a guiding passage portion 201a (see FIG. 37) whose depth in the front - rear direction is slightly larger than the outer diameter of the pachinko ball B. The entire bottom surface of the upper dish 201 including the guiding passage portion 201a is inclined so that the right - hand side is lower, and the right - hand side of the guiding passage portion 201a when viewed from the front dives below the ball - lending operation unit 220.

[0361] When the upper dish 201 is assembled to the dish unit 200, its bottom surface is inclined so as to become lower from a position below the upper - dish ball supply port 211a of the dish unit base 211 toward a position slightly below the outer diameter of the pachinko ball B with respect to the upper end of the upper - dish ball feeding port (not shown). Thereby, the pachinko ball B discharged forward from the upper - dish ball supply port 211a can be received and stored in the upper dish 201, and the received pachinko ball B can be supplied from the right - hand side of the guiding passage portion 201a through the upper - dish ball feeding port to the ball feeding unit 140 side.

[0362] Note that the guiding passage portion 201a is provided with a metal earthing fitting that is electrically grounded (earthed) in the pachinko machine 1, and when the pachinko ball B contacts (rolls), the static electricity charged on the pachinko ball B can be removed.

[0363] [3 - 5b. Lower dish] The lower dish 202 of the dish unit 200 will be described in detail mainly with reference to FIG. 48 and the like. The lower dish 202 is disposed below the upper dish 201 and to the left of the center in the left-right direction of the dish unit 200 (door frame 3) when viewed from the front. The lower dish 202 is formed by a lower dish main body 251 and a dish unit base 211. The lower dish 202 is formed in a container shape capable of storing the game balls B, and is provided with a lower dish ball discharge hole 202a that penetrates vertically through the bottom wall and enables the discharge of the game balls B (see FIG. 29). The lower dish ball discharge hole 202a of the lower dish 202 is closably closed by a lower dish ball discharge lid of the lower dish ball discharge unit 260.

[0364] The lower dish 202 is formed in a substantially rectangular shape extending left and right in plan view, and the front end on the left side of the center in the left-right direction protrudes forward more than the right side. The lower dish ball discharge hole 202a that penetrates vertically through the lower dish 202 is disposed near the front end near the right end. The bottom surface of this lower dish 202 is inclined so as to become lower toward the lower dish ball discharge hole 202a. The lower dish ball discharge hole 202a of the lower dish 202 is located to the left of and below the effect operation unit 300 in front of the lower dish ball supply port 211c in a state assembled to the dish unit 200.

[0365] The lower dish 202 can store the game balls B discharged forward from the lower dish ball supply port 211c in a state where the lower dish ball discharge hole 202a is closed, and can discharge the stored game balls B to below the dish unit 200 (for example, the dollar box) by opening the lower dish ball discharge hole 202a. Further, in a state where the lower dish ball discharge hole 202a of the lower dish 202 is open, since the lower dish ball discharge hole 202a is disposed in front of the lower dish ball supply port 211c, the game balls B discharged forward from the lower dish ball supply port 211c can be quickly discharged downward from the lower dish ball discharge hole 202a by moving the shortest distance.

[0382] [3-5c-5. Unit after the upper plate ball discharge] Regarding the unit before the upper plate ball discharge and the unit 240 after the upper plate ball discharge in the plate base unit 210, a detailed explanation will be mainly given with reference to FIG. 49. The unit 240 after the upper plate ball discharge is for discharging the game balls B stored in the upper plate 201 to the lower plate 202 in cooperation with the ball feeding unit 140 when the upper plate ball discharge button 222 of the ball lending operation unit 220 is pressed.

[0383] The unit 240 after the upper plate ball discharge includes a rear base 241 attached to the rear surface of the plate unit base 211 so as to close the upper plate ball feeding port from the rear, an upper plate ball discharge slider 242 slidably attached in the vertical direction to the front surface of the rear base 241, a spring (not shown) biasing the upper plate ball discharge slider 242 upward, and a rear cover 244 attached to the rear side of the rear base 241.

[0384] The rear base 241 protrudes upward from the part where the upper plate ball-removing slider 242 is slidably attached and opens forward, and has a ball receiving port (not shown) through which the game ball B can pass. It also has a ball feeding guide path that guides the game ball B received at the ball receiving port downward on the rear surface of the rear base 241 and then guides it rearward, and a ball removing guide path 241c that guides the game ball B downward from a position below the ball feeding guide path on the rear surface of the rear base 241 and then guides it rightward in a rear view.

[0385] The ball receiving port is formed at a position that opens forward through the upper plate ball feeding port of the dish unit base 211 at the downstream end (right end in a front view) of the guiding passage portion 201a of the upper plate 201 in a state assembled to the dish base unit 210. The ball feeding guide path is formed in a state assembled to the door frame 3 such that the inlet 141a of the ball feeding unit 140 is located at the rear of the lower part. As a result, the game ball B supplied to the upper plate 201 enters the inlet 141a of the ball feeding unit 140 through the ball receiving port and the ball feeding guide path.
