[0006] Means of the present invention: In the gaming machine, "Game ball on the front side A gaming machine including a game board provided with a game area through which a game ball flows down. A specific flow path portion provided on the game board, in which a rear member and a front member are combined to form a flow path for the game ball. A predetermined stage portion provided on the game board. The front member of the specific flow path portion is provided with a convex portion formed to protrude rearward from the rear surface so as to be able to affect the flowing-down state of the game ball, and a concave portion formed on the front surface opposite to the rear surface where the convex portion is formed. A predetermined front decorative portion is arranged so as to overlap the concave portion and the convex portion in a front view. A predetermined light-emitting portion is arranged behind the specific flow path portion, and the convex portion, the concave portion, and the front decorative portion can be irradiated with the light of the light-emitting portion. The stage portion has a demolding trace portion generated in the molding process. The stage portion includes a bottom wall member that forms the bottom surface and rolls the game ball in the left-right direction, and a rear wall member that forms the rear wall surface. The bottom wall member is provided with a ball discharge portion that allows the rolling game ball to fall toward a specific area. On the bottom wall member, a demolding trace portion is provided so as to be substantially symmetric about the virtual center line of the ball discharge portion. It is characterized by the following. And, as an invention different from the present invention, the following means are exemplified. Means 1: In a gaming machine, A gaming machine in which a game board having a game area where game balls flow down is housed in a main body frame, The main body frame is pivotally supported by an outer frame, The game is played by hitting a game ball into the game area by the operation of a player, A lottery is conducted by a predetermined trigger, and a privilege is given to the player according to the result of the lottery, Furthermore, an operation unit that affects the effect by the operation of the player is provided on the front surface of the gaming machine, The game board includes a game board having an opening, and a center frame is provided in the opening, The center frame, Is provided with a protruding wall portion that protrudes forward from the front surface of the game board, A demolding trace portion is provided on the front end surface of the protruding wall portion It is characterized by the following.

[0007] Here, the "center frame" constitutes a center accessory, and may be a frame-shaped one along the edge of the opening of the game board, or may be divided into a plurality in the direction along the edge of the opening of the game board. Further, the "center frame" may be composed of one member or a plurality of members.

[0008] In addition, examples of the "protruding wall portion" include "one that protrudes forward from the front surface of the game board by a length longer than the radius (or diameter) of the game ball", "one that protrudes forward by the same length as from the front surface of the game board to the front end of the obstacle pins implanted in the game board", and the like.

[0009] Furthermore, the "demolding trace portion" refers to the trace left on the molded product by a mechanism (such as an ejector pin, a push-up core, a straight-up core, a protruding core, etc.) for removing the molded product from the mold (die). Compared with other parts, it is slightly concave, convex, or inclined. Examples of the shape of this "demolding trace portion" include "a shape of a part of a circle like a semi-circle", "a circle", "a triangle", "a quadrilateral", "a pentagon", "a hexagon", "a polygon", "an irregular shape", "a star shape", "a heart shape", and so on.

[0010] According to the configuration of Means 1, a gaming machine includes a gaming board having a center frame attached to the opening edge of the gaming board. The center frame includes a protruding wall portion that protrudes forward from the front surface of the gaming board, and a demolding trace portion is provided on the front end surface of the protruding wall portion (refer to the description of [5-8c-2c. Demolding Trace Portion of the Forward Protruding Portion], Demolding Trace Portion 2519, Center Frame 2510, Forward Protruding Portion 2511, FIGS. 113 and 118, etc. in [Modes for Carrying Out the Invention]).

[0011] As a result, since the center frame attached to the opening edge of the gaming board is provided with a protruding wall portion that protrudes forward, the protruding wall portion can prevent the game ball from dropping (invading) into the opening of the gaming board, and a region (gaming region) where the game ball flows down can be formed at a portion outside the center frame on the front surface of the gaming board. The player can be entertained by the movement of the game ball flowing down in this region. And because a demolding trace portion formed during the molding of the center frame (molded product) is provided on the front end surface of the protruding wall portion of the center frame, the center frame can be made prominent by the visibility of the demolding trace portion, and the player's interest can be attracted to the center frame. Therefore, the demolding trace portion provided on the front end surface of the protruding wall portion of the center frame can make the player recognize that a center frame completely different from the conventional one is provided, strongly attract the player's interest, and provide a gaming machine with a high appeal to the player.

[0012] In addition, since the demolding trace portion has a different form compared to other portions in the center frame, when light from a liquid crystal display device, an LED, etc. provided at the rear hits it, it will emit a different light pattern than other portions. As a result, on the front end face of the protruding wall portion in the center frame, the demolding trace portion will stand out by emitting a different light pattern than other portions, strongly attracting the attention of the player, and at the same time, the center frame can be made to look nice by the demolding trace portion shining.

[0013] In addition, after providing the protruding wall portion with a partitioning portion that divides the game area through which the game balls flow into two, the front end face of the partitioning portion may not be provided with a demolding trace portion. As a result, on the front end face of the partitioning portion in the protruding wall portion of the center frame that divides the game area into two, since no demolding trace portion is provided, it is possible to make the player recognize that the partitioning portion is a different portion from the portion where the demolding trace portion is provided in the protruding wall portion, and it is possible to make the player recognize that the partitioning portion is not a portion that constitutes the frame, and it is possible to make the player recognize that the game area 5a is divided into left and right.

[0014] Also, when the front end face of the partitioning portion is not provided with a demolding trace portion as described above, since the partitioning portion becomes less prominent than the portion where the demolding trace portion is provided in the protruding wall portion, it is possible to make it difficult for the player to notice the existence of the partitioning portion, and it is possible to make the player have the illusion that the game balls can move back and forth across the portion of the partitioning portion.

[0015] Also, it is desirable to make the forms of the adjacent demolding trace portions uniform. As a result, the demolding trace portions provided on the front end face of the protruding wall portion in the center frame can be made to look like a pattern, and the appearance of the center frame can be improved.

[0016] Means 2: In the configuration of Means 1, "The protruding wall portion has a partitioning portion that divides the game area through which the game balls flow into two, and the front end face of the partitioning portion is not provided with the demolding trace portion" It is characterized by being such.

[0017] Here, as the "partition part", there can be mentioned "the part extending vertically provided at the end (for example, the right end) of the stage provided within the frame of the center frame", "the part extending downward from the center frame", "the part partitioning a plurality of ball passages on the left or right side of the center frame", etc.

[0018] According to the configuration of means 2, the protruding wall part has a partition part that divides the game area through which the game balls flow into two, and no demolding trace part is provided on the front end face of the partition part (refer to the description of the partition part 2511a of the front protruding part 2511 in [Mode for Carrying Out the Invention]).

[0019] As a result, since no demolding trace part is provided on the front end face of the partition part of the protruding wall part of the center frame that divides the game area into two, it becomes possible to make the player recognize that the partition part is a different part from the part where the demolding trace part is provided on the protruding wall part, and it can be made to be recognized that the partition part is not a part constituting the frame, and it can be made to be recognized that the game area 5a is divided into left and right.

[0020] Alternatively, since no demolding trace part is provided on the front end face of the partition part, the partition part becomes less conspicuous than the part where the demolding trace part is provided on the protruding wall part, and it can be made difficult to notice the existence of the partition part, and it can be made to give the player an illusion that the game balls can go back and forth across the part of the partition part.

[0021] Means 3: In the configuration of means 1 or means 2, the gaming machine, has a game area in front of the game board where game balls flow down, and a winning port through which game balls can enter is provided in the game area, and it is characterized by being a pachinko machine that gives a predetermined privilege when game balls enter the winning port.

[0022] Here, as the "winning openings", there are "general winning openings that are always open within the game area", "starting winning openings (starting openings) that are always open within the game area and in which a lottery of special symbols is conducted to determine whether a favorable gaming state that benefits the player as a predetermined privilege is generated when a game ball enters", "variable winning openings (variable starting openings, accessory winning openings, 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) within the game area", "variable winning openings (variable starting openings, accessory winning openings, etc.) in which a game ball can enter as a predetermined privilege according to the lottery result of ordinary symbols selected when the game ball passes through a specific area (gate, through chucker, etc.) within the game area", "variable starting winning openings (variable starting openings) in which a game ball can enter as a predetermined privilege according to the lottery result of ordinary symbols selected when the game ball passes through a specific area (e.g., gate, chucker, etc.) within the game area, and in which a lottery of special symbols is conducted to determine whether a favorable gaming state that benefits the player as a predetermined privilege is generated when the game ball enters", "V winning openings 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 that benefits the player as a predetermined privilege is generated", "large winning openings and accessory winning openings that open and close in a predetermined pattern and allow the entry of game balls as a favorable gaming state that benefits the player as a predetermined privilege", etc.

[0023] In addition, as a "pachinko machine", there is one "equipped with a lottery means for conducting a special symbol lottery to generate an advantageous gaming state in which a player is advantaged as a predetermined privilege by the entry of a gaming ball into the start opening, a special lottery result display means as a display for variably displaying a special symbol according to the lottery result of the special symbol selected by the lottery means and then stopping and displaying it, and displaying a special lottery result selected by the combination of the stopped and displayed special symbols, and an advantageous gaming state generating means for opening and closing a big winning opening in a predetermined pattern when a special lottery result for generating an advantageous gaming state is displayed in the special lottery result display means (so-called digital pachinko machine)", one "equipped with a distributing means for distributing the gaming balls that have entered the accessory winning opening, and an advantageous gaming state generating means for opening and closing the accessory winning opening in a predetermined pattern as a predetermined privilege when the gaming balls distributed by the distributing means enter the V winning opening, thereby generating an advantageous gaming state in which the player is advantaged (so-called winged machine)", one "having a big winning opening and an accessory winning opening, opening and closing the big winning opening or the accessory winning opening in a predetermined pattern according to the lottery result of the special symbol selected by the entry of a gaming ball into the start opening (start entry), and when the gaming balls that have entered the accessory winning opening are distributed to the V winning opening, opening and closing the accessory winning opening or the big winning opening in a predetermined pattern as a predetermined privilege, thereby generating an advantageous gaming state in which the player is advantaged, and having an advantageous gaming state generating means (so-called composite machine)", and the like.

[0024] According to the configuration of means 3, the gaming machine has a gaming area where gaming balls flow down in front of the game board, and a winning opening through which gaming balls can enter the gaming area is provided. By the entry of a gaming ball into the winning opening, it is a pachinko machine that confers a predetermined privilege.

[0057] The lower right connecting member 23 is for connecting the lower end of the outer frame right member 21 and the right end of the outer frame lower assembly 40 (outer frame lower member 41). 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 rear side of the horizontal fixing portion 23a on the lower side of the upper horizontal fixing portion 23b, and a flat plate-shaped abutting portion 23d that extends short to the left 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.

[0058] The lower right connecting member 23 is attached to the right outer frame member 21 by screwing a screw into the upper horizontal fixing portion 23b from the outside of the right side of the right outer frame member 21, with the rear surface of the abutting portion 23d abutting against the front surface of the bulging portion 21b of the right outer frame member 21, the right side of the upper horizontal fixing portion 23b abutting against the left side of the right outer frame member 21, and the lower surface of the horizontal fixing portion 23a being aligned with the lower end of the right outer frame member 21.

[0061] [2-2. Upper outer frame member] The upper outer frame member 30 of the outer frame 2 will be described in detail mainly with reference to Figure 16. The upper outer frame member 30 is used to connect the upper ends of the left outer frame assembly 10 and the right outer frame assembly 20, which are spaced apart laterally. The upper outer frame member 30 has a width in the front-to-rear direction that is approximately the same as the width of the left outer frame member 11 and the right outer frame member 21 in the front-to-rear direction, a constant thickness in the up-down direction, extends in the left-to-right direction, and is made of wood. The left-to-right length of the upper outer frame member 30 is formed to be the same as the left-to-right length of the lower outer frame member 41 of the lower outer frame assembly 40, which will be described later.

[0062] The upper outer frame member 30 is provided with cutout portions 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 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 cutout portions 30a at both left and right ends in a state of being inserted therein.

[0063] Further, the upper outer frame member 30 is provided with a mounting step portion 30b at the left - hand end portion, where the upper surface and the front surface are recessed more than the general surface. The outer - frame upper hinge assembly 50, which will be described later, is attached to this mounting step portion 30b.

[0064] [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. The lower outer - frame assembly 40 connects the lower ends of the left outer - frame assembly 10 and the right outer - frame assembly 20 that are spaced apart from each other left and right, and is for closing and decorating the lower side of the door frame 3 in the pachinko machine 1.

[0065] The lower outer - frame assembly 40 includes an outer - frame lower member 41 that connects the lower ends of the left outer - frame assembly 10 and the right outer - frame assembly 20 that are spaced apart from each other left and right and extends left and right, a box - shaped front curtain - plate 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 is open at the rear, a box - shaped rear curtain - plate member 43 that is attached to the rear side of the front curtain - plate member 42, is attached to the upper surface of the outer - frame lower member 41, extends left and right, and is open at the front, and a ball - biting prevention mechanism 44 formed at the left end on the upper surface of the rear curtain - plate member 43.

[0066] 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 outer - frame member 11 and the right outer - frame member 21, has a constant thickness in the up - down direction, extends in the left - right direction, and is formed of wood. The length of the outer - frame lower member 41 in the left - right direction is formed to be the same as the length of the upper outer - frame member 30 in the left - right direction.

[0067] The lower outer frame member 41 has cutouts 41a at the center of the front-to-rear direction on both left and right sides, which penetrate vertically and are recessed toward the center in the left-to-right direction. The lower lateral fixing portion 13c of the lower left connecting member 13 and the lower lateral fixing portion 23c of the lower right connecting member 23 are inserted into these cutouts 41a at both ends. This allows the lower ends of the left outer frame member 11 and the right outer frame member 21 to be connected to each other.

[0068] The outer frame lower member 41 is recessed from the top surface and has a recess 41b into which the lower part of the header rear member 43 is inserted. The recess 41b extends left and right and extends from a position toward the rear of the center in the front-to-rear direction to the front end. This recess 41b maximizes the volume of the header internal space 40a formed by the header front member 42 and the header rear member 43.

[0069] The front panel member 42 has the same left-right length as the outer frame lower member 41, is formed in the shape of a horizontally elongated rectangular box with a short depth in the front-to-back direction relative to its height, and is open on the entire rear side. The open rear side of the front panel member 42 is closed by the rear panel member 43, thereby forming, in cooperation with the rear panel member 43, a front panel internal space 40a that becomes part of the enclosure 624 of the main frame speaker 622. The front panel member 42 has an elongated opening 42a on the front surface near the right end that penetrates from front to back and extends left to right.

[0070] The rear panel member 43 has a length in the left-right direction slightly shorter than that of the lower outer frame member 41 and is formed in a box shape with an open front. By attaching the front panel member 42 to the front surface of the rear panel member 43, the rear panel member 43 cooperates with the front panel member 42 to form the panel internal space 40a, which is part of the enclosure 624 of the main frame speaker 622. The rear panel member 43 has a cylindrical connecting tube portion 43a in the center of the left-right direction on its upper surface, which extends left and right and protrudes upward to communicate with the panel internal space 40a. The connecting tube portion 43a is inclined so that its upper end is positioned upward from the front end side, which is coincident with the general upper surface of the rear panel member 43, toward the rear. In this embodiment, the upper end of the connecting tube portion 43a is inclined at a 45-degree angle.

[0071] 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. A plurality of ribs 43b connecting the front - end side and the rear - end side are provided inside the connecting cylinder portion 43a. 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.

[0072] 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 hinge member 60 of the outer frame at the left end on the upper surface of the rear curtain member 43.

[0073] 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 hinge member 60 of the outer frame, which will be described later, can be 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 located 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 has an upper surface inclined so as to be positioned upward as it goes rearward.

[0074] The first discharge port 44b is formed at a position that coincides with the discharge hole 60d of the lower hinge member 60 of the outer frame, which will be 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, and open on 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.

[0075] When an improper tool such as a piano wire is inserted through the gap between the outer frame lower hinge member 60 and the main body frame lower hinge assembly 520 described later, this ball jamming prevention mechanism 44 can prevent the intrusion of the improper tool by means of a standing wall portion 44d rising from the rear end of the placement portion 44a. Even if the tip of the improper tool abuts against the standing wall portion 44d and bends upward, it can abut against an upper end protruding portion 44e protruding forward provided at the upper end of the standing wall portion 44d, thereby preventing further intrusion. Therefore, it is possible to prevent improper acts from being performed through the portion of the outer frame lower hinge member 60.

[0076] By the way, when the standing 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 prevented from moving rearward of the outer frame 2 by the standing 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 is sandwiched between the outer frame 2 and the main body frame 4, and a problem occurs that the main body frame 4 cannot be closed.

[0077] On the other hand, in the ball jamming prevention mechanism 44 of the present 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 (rear of 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, and it is possible to prevent the game ball B from being sandwiched between the outer frame 2 and the main body frame 4.

[0078] 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.

[0079] 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.

[0080] The grill member 46 is in a strip shape extending in the left-right direction and has a plurality of blade parts 46b provided at intervals in the up-down direction. The blade parts 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 inside (the curtain plate internal space 40a) and the outside of the curtain plate front member 42 to communicate with each other through the gaps between the blade parts 46b so as to be ventilable.

[0081] The port member 47 allows the curtain plate internal space 40a (enclosure 624) and the front of the outer frame 2 to communicate with each other through the gaps between the blade parts 46b in 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, and can radiate rich bass to the front of the outer frame 2 (the player side). That is, in the present embodiment, the enclosure 624 of the main body frame speaker 622 is of the bass reflex type, and can let the player hear the heavy bass.

[0082] The seal member 48 is sandwiched and compressed between the upper end of the connection cylinder part 43a and the lower end of the connection part 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, and prevents the sound inside the enclosure 624 of the main body frame speaker 622 from leaking from between the connection cylinder part 43a and the connection part 621c.

[0083] According to the grill member 46 of this embodiment, the air vibrations emitted to the outside from the header internal space 40a by the main body frame speaker 622 can be directed by the inclined blade portions 46b through the notched opening 295b on the lower side of the handle cover 295 of the handle cover unit 290 located diagonally upward and forward, into the front cylinder portion 291a of the handle cover base 291 that houses the handle unit 180. As a result, when a player inserts his or her fingers inside the handle cover 295 (the front cylinder portion 291a of the handle cover base 291) and rotates the handle 197 (the device for striking the game ball B), the main body frame speaker 622 is vibrated to send air into the front cylinder portion 291a, surprising the player and providing an unprecedented performance.

[0084] Furthermore, since the port member 47 is open toward the front, a portion of the sound pressure emitted from the port member 47 through the multiple blade portions 46b of the grill member 46 is emitted forward, so that the sound effects emitted from the port member 47 can be heard by players seated in front of the pachinko machine 1 and other players wandering around the gaming hall where the pachinko machine 1 is installed, and the sound effects can also attract the attention of players, making it possible to provide a pachinko machine 1 that is highly appealing to players.

[0085] Furthermore, since the port member 47 is provided in the lower outer frame assembly 40 of the outer frame 2, the volume of the enclosure 624 of the main frame speaker 622 provided in the main frame 4 can be increased, making it possible to output a more deep bass sound, which entertains the player and prevents a decline in interest.

[0086] [2-4. Outer frame upper hinge assembly] The upper hinge assembly 50 on the outer frame 2 of the outer frame will be described in detail mainly with reference to FIG. 19. FIG. 19(a) is an exploded perspective view of the upper hinge assembly on the outer frame 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 hinge assembly 50 on the outer frame is attached to the upper end of the left outer frame assembly 10 and the left end of the upper outer frame member 30, and is for rotatably attaching the main body frame 4 to the outer frame 2 by a hinge. The upper hinge assembly 50 on the outer frame includes an upper hinge member 51 attached to the upper end of the concave portion 11a of the left outer frame member 11 and the mounting step portion 30b of the upper outer frame member 30, a lock member 52 attached to the upper hinge member 51, and a mounting screw 53 for attaching the lock member 52 to the upper hinge member 51.

[0087] The upper 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 outer 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 horizontal 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 from the left side of the front extension portion 51b around the front side to the portion where the bearing groove 51c opens and continuous with the horizontal fixing portion 51d. The upper hinge member 51 is formed by punching and bending a metal plate by press forming. The upper hinge member 51 can rotatably support a main body frame upper hinge pin 512 (described later) of the main body frame upper hinge member 510 in the bearing groove 51c.

[0088] 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.

[0089] When the lock member 52 is mounted on 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.

[0090] By operating the operation piece 52b, the lock body 52a of the lock member 52 can be rotated 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 completely 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.

[0091] [2-5. Lower hinge member of the outer frame] The lower hinge member 60 of the outer frame 2 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 from near the front end of the horizontal portion 60a, and a discharge hole 60d that penetrates the horizontal portion 60a vertically and is sized such that only one game ball B can pass through. This lower hinge member 60 of the outer frame is formed by punching and bending a metal plate by press molding.

[0092] 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 base in a plan view. The outer frame lower hinge pin 60c is cylindrical, and the upper part above the center in the vertical direction is formed in a frustum shape with a narrowed upper end. This outer frame lower hinge pin 60c is attached at a position near the front end of the horizontal portion 60a and to the left. The discharge hole 60d is formed in the horizontal portion 60a in contact with the central portion in the front-rear direction of the upright portion 60b and extending 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 be approximately the same size as the first discharge port 44b of the ball biting prevention mechanism 44 in the lower outer frame assembly 40.

[0093] 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 lower outer frame 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 lower hinge assembly 520 of the main body frame of the main body frame 4.

[0094] In addition, in the assembled state of the outer frame 2, 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. As a result, 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 the main body frame 4 is closed 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 that it rolls toward the rear side with a wide 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 of being assembled to the pachinko machine 1, it is possible to easily 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.

[0127] 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.

[0128] 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 attachment 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.

[0129] The upper reinforcing frame 113 extends horizontally with a width that is constant in the vertical direction and a length substantially the same as the left and right widths of the door frame base 101.

[0130] 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 is aligned with the through hole of the door frame base 101, and the cylinder attachment frame 115 is inserted into the cylinder insertion hole 101d of the door frame base 101.

[0131] [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 wider in the vertical direction 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 plate ball passage port 101g of the door frame base 101.

[0132] 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.

[0133] Further, a plurality of bead portions 117e that protrude forward and are long in the left-right direction are provided on the substrate portion 117a of the intermediate reinforcement frame 117. The strength and rigidity of the substrate portion 117a (intermediate reinforcement frame 117) are enhanced by these plurality of bead portions 117e.

[0134] 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 thickness thicker than that of 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 by a plurality of rivets at the site of their respective substrate parts 117a with the first sheet metal part 118a facing forward.

[0135] 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. Incidentally, the thickness tc of the second sheet metal part 118b is about 1.7 times the thickness of the first sheet metal part 118a.

[0136] In the state of being assembled to the door frame 3, this intermediate reinforcing frame 117 is located below the door window 101a and behind the dish unit 200 (the production operation unit 300 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 of the glass unit 160 and the rearward movement of the lower part of the glass unit 160. In this 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.

[0137] In the intermediate reinforcing 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 parts with larger upper and lower widths are attached to the left reinforcing frame 111 and the right reinforcing frame 112, it is attached more firmly than the intermediate reinforcing frame in the conventional door frame.

[0138] Also, the intermediate reinforcing 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 reinforcing 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 reinforcing frame 117 has higher strength and rigidity than the intermediate reinforcing frame 114 of the door frame 3 in the first embodiment. Therefore, the door frame reinforcing unit 110 itself also has higher strength and rigidity than the door frame reinforcing unit of the conventional door frame.

[0139] In this way, since the strength and rigidity of the intermediate reinforcing frame 117 (door frame reinforcing 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 reinforcing frame 117 (door frame reinforcing 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 reinforcing frame 117.

[0140] 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 reinforcing frame 117 (door frame reinforcing unit 110) with enhanced strength and rigidity prevents the door frame 3 from plastically deforming 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.

[0141] Further, since 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, not only can the load of the glass unit 160 be supported, but also 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 the pachinko machine 1 with a high deterrent force against unauthorized acts can be provided.

[0142] In addition, 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. Further, 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 game board 5 at the rear is set according to the angle at which the rear flange portion 117c is extended (bent) with respect to the upper flange portion 117b.

[0143] [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.

[0144] (Modification Example 1 of Intermediate Reinforcing Frame) The intermediate reinforcing frame 117A shown in Fig. 39(a) is composed of a single thick metal plate (sheet metal). The intermediate reinforcing frame 117A also has the same effects as described above. Further, according to this intermediate reinforcing 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 reinforcing frame 117A.

[0145] (Modification Example 2 of Intermediate Reinforcing Frame) The intermediate reinforcing 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 reinforcing 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 reinforcing 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-described intermediate reinforcing frame 117. Also, a bead portion 117e may be provided on the intermediate reinforcing frame 117B.

[0146] (Modification Example 3 of Intermediate Reinforcing Frame) In the intermediate reinforcing 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 reinforcing frame 117C also has the same effects as described above. Further, in this intermediate reinforcing frame 117C, since the width (depth) of the upper flange portion 117b in the front-rear direction is made wider than the upper flange portion 117b of the above-described intermediate reinforcing frame 117, the glass unit 160 can be received in a wide range. Note that the intermediate reinforcing 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-described intermediate reinforcing frame 117. Also, a bead portion 117e may be provided on the intermediate reinforcing frame 117C. Further, a locking piece 16b similar to the above may be provided on the glass frame 161 of the glass unit 160.

[0147] (Modification Example 4 of the Intermediate Reinforcement Frame) In the intermediate reinforcement frame 117D shown in Fig. 40(a), 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 enhanced, and even if the upper plate 201 or the lever operation portion 304 of the door frame 3 is strongly pulled forward, it 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 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.

[0148] (Modification Example 5 of the Intermediate Reinforcement Frame) In the intermediate reinforcement frame 117E shown in Fig. 40(b), 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 enhanced, and even if the upper plate 201 or the lever operation portion 304 of the door frame 3 is strongly pulled forward, it 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, inside 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 unauthorized tool tries 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 unauthorized acts can be enhanced.

[0149] The rear flange portion 117c of the intermediate reinforcement frame 117E may be configured to contact the gaming board 5. This allows the door frame 3 and the gaming board 5 to be positioned via the rear flange portion 117c, and the gaming board 5 to be supported by the rear flange portion 117c. When the rear flange portion 117c is configured to contact the gaming board 5, it may be grounded to the gaming board 5. The intermediate reinforcement frame 117E may be configured from a single metal plate as shown in the figure, or may be configured from multiple metal plates like the intermediate reinforcement frame 117 described above. The intermediate reinforcement frame 117E may also be provided with a bead portion 117e. The glass frame 161 of the glass unit 160 may also be provided with a locking piece 161b similar to the above.

[0150] [3-1e-3. Other countermeasure examples] Next, we will explain measures to prevent a gap from being formed between the door frame 3 and the main frame 4 when the upper tray 201 or the like is pulled forward. As a specific example 1, for example, a distance sensor (e.g., a simple switch, optical sensor, magnetic sensor, proximity sensor, displacement sensor, etc.) may be provided to detect the distance (change in distance) between the game board 5 and the vicinity of the center in the left-right direction of the intermediate reinforcement frame 117, and when the signal from the distance sensor exceeds a predetermined threshold, an alarm may be issued to that effect. In this case, the distance sensor may be provided on the main frame 4, the game board 5, or the door frame 3.

[0151] 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 does not undergo plastic deformation. 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 anti-theft effect can be provided.

[0152] Also, as a 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 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 reports it. 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.

[0153] Furthermore, as a 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, it may report that fact.

[0154] 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 reinforcing 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 reinforcing 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 reinforcing frame 117 from bulging forward (plastic deformation or elastic deformation) due to the locking of the intermediate hook.

[0155] [3-1e-4. Small brackets] The above-described door frame reinforcing unit 110 has the following technical features.

[0156] (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 end sides 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.

[0157] 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 part of the open side end of the reinforcing sheet metal opposite to the hinge side, so that the door frame cannot be opened even if it is pulled forward (for example, Patent Document: Japanese Patent Application Laid-Open No. 2008-110159).

[0158] 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, the door frame (reinforcing sheet metal) may be distorted so that the center in the left-right direction of the door frame bulges forward. 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.

[0159] Therefore, in consideration of the above-mentioned situation, the following means aims to provide a gaming machine that makes it difficult for a gap to form between the door frame and the main body frame even when the door frame is pulled, thereby preventing fraudulent acts that use such gap.

[0160] (Technical feature solution) Means 1: In the gaming machine, "A main frame 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 play area to be viewed from the front and that is provided so as to be openable and closable from the front relative to the main body frame; A gaming machine equipped with: The door frame is a reinforcing sheet metal unit having a first reinforcing portion extending laterally along a lower edge of the window portion, The first reinforcing portion is a substrate portion parallel to an opening surface of the window portion; an upper flange portion extending rearward from an upper edge of the base plate portion; a rear flange portion extending upward or downward from a rear end edge of the upper flange portion; It is characterized by being equipped with the following features.

[0161] Here, examples of the "first reinforcing portion" include "one made of one metal plate (sheet metal)" and "one made of multiple metal plates (sheet metal)."

[0162] According to the configuration of means 1, there is 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 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. 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 [Mode for Carrying Out the Invention].

[0163] 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 enhanced compared to the conventional ones, 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 form a gap between the door frame and the main body frame by pulling the door frame forward to perform an illegal act, the door frame will not be distorted by the first reinforcing portion (reinforced sheet metal unit) with enhanced strength and rigidity, and a game machine with a high deterrent force against illegal acts can be provided.

[0164] 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 more enjoyable.

[0165] In addition, 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 of supporting the glass unit by a resin member (for example, a door frame base) made of synthetic resin that constitutes the door frame, the load applied to the resin member can be reduced, and early deterioration due to overloading in the resin member can be suppressed.

[0166] Also, when placing the glass unit 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 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.

[0167] 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, compared with the case where the length is short, the strength and rigidity of the first reinforcing portion can be increased, and the door frame can be made less likely to distort even when pulled forward.

[0168] 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 unauthorized tool tries to intrude along the front surface of the game board, the intrusion of the unauthorized tool can be blocked by the rear flange portion inserted into the game board, and a gaming machine with a high deterrent force against unauthorized acts can be provided.

[0169] 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 the 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.

[0170] Furthermore, it is desirable to make the thickness of the first reinforcing portion thicker than the thickness of the sheet metal of the other reinforcing portions in the reinforcing sheet metal unit. Thereby, since the thickness of the first reinforcing portion is made thicker than the thickness 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.

[0171] 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 this 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.

[0172] Means 2: In the configuration of Means 1, "The upper flange portion is where a glass unit for closing the window portion is placed." is characterized by this.

[0173] 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])

[0174] 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 of having the glass unit 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 overloading in the resin member can be suppressed.

[0175] Further, 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 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. Thus, 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.

[0176] 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" characterized by.

[0177] 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. (Refer to the description of the intermediate reinforcing frame 117 and FIG. 38 etc. in [Embodiments for Carrying Out the Invention])

[0178] 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.

[0179] Also, 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 improper tool tries to intrude along the front surface of the game board, the intrusion of the improper tool can be blocked by the rear flange portion inserted into the game board, and a gaming machine with a high deterrent force against improper acts can be provided.

[0180] Means 4: In any one of the configurations from Means 1 to Means 3, "The first reinforcing part is provided with a lower flange part extending forward or backward from the lower edge of the substrate part." It is characterized by this.

[0181] According to the configuration of Means 4, the first reinforcing part is provided with a lower flange part extending forward or backward from the lower edge of the substrate part. (Refer to the description of the lower flange part 117d and FIG. 36 etc. in [Mode for Carrying Out the Invention])

[0182] Thereby, in the first reinforcing part, in addition to providing an upper flange part extending backward from the upper edge of the substrate part, a lower flange part extending forward or backward from the lower edge of the substrate part is provided. Therefore, the strength and rigidity of the first reinforcing part can be further increased, and a gaming machine capable of surely achieving the above-described operational effects can be provided.

[0183] Means 5: In any one of the configurations from Means 1 to Means 4, "The first reinforcing part has a greater plate thickness than the sheet metal of other reinforcing parts in the reinforcing sheet metal unit." It is characterized by this.

[0184] According to the configuration of Means 5, the first reinforcing part has a greater plate thickness than the sheet metal of other reinforcing parts in the reinforcing sheet metal unit. (Refer to the description of the intermediate reinforcing frame 117 and FIG. 36 etc. in [Mode for Carrying Out the Invention])

[0185] Thereby, since the plate thickness of the first reinforcing part is made greater than the plate thickness of other reinforcing parts, the strength and rigidity of the first reinforcing part can also be increased by this, and a gaming machine capable of achieving the same operational effects as described above can be provided.

[0186] Incidentally, the first reinforcing portion 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).

[0187] Means 6: In any one of the configurations from Means 1 to Means 5, "further comprising a distance sensor for detecting the distance between the first reinforcing portion and the game board". It is characterized by this.

[0188] Here, examples of the "distance sensor" include "switch", "optical sensor", "magnetic sensor", "proximity sensor", "displacement sensor", etc. The distance sensor may be provided on the first reinforcing portion (door frame), may be provided on the game board, or may be provided on the main body frame. As a 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 can be designed in the same way as the input circuit of a 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 wired OR.

[0189] According to the configuration of Means 6, the gaming machine further comprises a distance sensor for detecting the distance between the first reinforcing portion and the game board. (Refer to the chapter of [3 - 1e - 3. Other countermeasure examples] in [Mode for Carrying Out the Invention])

[0190] 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, preventing the player from pulling the door frame too strongly unnecessarily or pulling the door frame strongly for illegal acts, and a gaming machine with a high anti-theft effect can be provided.

[0191] Thus, according to the above solution means, it is possible 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.

[0192] (Relationship between the solution means of the technical features and the embodiment) In the door frame base 101 of the door frame base unit 100 of the door frame 3 of the present embodiment, the door window 101a of the door frame base 101 corresponds to the window portion of the above 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 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 solution means, respectively.

[0193] (Characteristic operational effects of the present embodiment) According to the pachinko machine 1 of this embodiment, since a door frame reinforcement 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 reinforcement unit 110. This door frame reinforcement unit 110 has an intermediate reinforcement frame 117 that extends in the left-right direction along the lower side of a door window 101a of the door frame 3. The intermediate reinforcement frame 117 is provided with a flat plate-shaped substrate portion 117a, an upper flange portion 117b that extends rearward from the upper edge of the substrate portion 117a, and a rear flange portion 117c that extends 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 reinforcement frame 117 (intermediate reinforcement frame 117A, intermediate reinforcement frame 117B, intermediate reinforcement 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 reinforcement frame 117D (intermediate reinforcement frame 117E) becomes a U shape. Therefore, the strength and rigidity can be made higher than those of a conventional reinforcement portion (intermediate reinforcement frame) having a linear or L-shaped cross-sectional shape. That is, since the strength and rigidity of the intermediate reinforcement frame 117 of the door frame reinforcement 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 reinforcement 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 reinforcement frame 117 (door frame reinforcement unit 110) having enhanced strength and rigidity, and a pachinko machine 1 with a high deterrent force against illegal acts can be provided.

[0194] Also, as described above, since the intermediate reinforcing frame 117 (door frame reinforcing 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 plate 201, the lower plate 202, the lever - shaped effect operation part (lever operation part 304), the protruding or projecting push - button - shaped effect operation part (pressing operation part 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.

[0195] Furthermore, since the glass unit 160 for closing the door window 101a is placed on the upper flange part 117b, the weight of the glass unit 160 can be supported by the upper flange part 117b (door frame reinforcing unit 110). Therefore, compared with the case of supporting the glass unit 160 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 the early deterioration due to over - load in the resin member can be suppressed.

[0196] Also, the glass unit 160 is placed on the upper flange part 117b, and the rear surface of the glass unit 160 abuts on the front surface of the rear flange part 117c that extends upward from the rear edge of the upper flange part 117b. Therefore, the rearward movement of the lower end side of the glass unit 160 can be blocked by the rear flange part 117c. Thereby, 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.

[0197] Furthermore, in the intermediate reinforcing frame 117, since the sum (L0) of the lengths (L1 and L2) in the direction along the respective surfaces of the upper flange part 117b and the rear flange part 117c is made longer than the length from the substrate part 117a to the front surface of the game board 5, the strength and rigidity of the intermediate reinforcing frame 117 can be increased compared with the case where the length is short, and the door frame 3 can be made difficult to distort even when pulled forward.

[0198] In addition, 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 as in 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.

[0199] In addition, 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.

[0200] 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.

[0201] Further, an interval sensor for detecting the interval between the intermediate reinforcing frame 117 and the game board 5 may be 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, when 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 this interval is provided. As a result, since the interval sensor can detect the change in the interval due to elastic deformation, 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.

[0202] [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 in 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 on 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 on 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 on the door frame, and a lock spring 124 biasing the upper hinge pin 122 on the door frame to move upward.

[0203] 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.

[0204] The upper door-frame hinge pin 122 is a cylindrical metal rod bent into an L-shape. When assembled to the upper door-frame hinge assembly 120, the portion of the upper door-frame hinge pin 122 that extends vertically penetrates from below near the front ends of a pair of protruding pieces 121b of the hinge bracket 121, with the upper end extending upward beyond the upper protruding piece 121b, and the portion that extends horizontally abuts against the underside of the lower protruding piece 121b. The upper end of the upper door-frame hinge pin 122 is rotatably inserted into the upper door-frame hinge hole 511a of the upper hinge body 511 of the main-frame upper hinge member 510 of the main frame 4.

[0205] The flange member 123 is an E-ring, and is attached to a portion of the upper door-frame hinge pin 122 between the pair of protruding pieces 121b. The lock spring 124 is formed in a coil shape, and is fitted around the portion of the upper door-frame hinge pin 122 that extends vertically, between the flange member 123 and the lower protruding piece 121b of the hinge bracket 121. The lock spring 124 urges the upper door-frame hinge pin 122 upward via the flange member 123.

[0206] In the upper door-frame hinge assembly 120, the upper door-frame hinge pin 122 is biased upward by the lock spring 124, and the horizontally extending portion of the lower end of the upper door-frame hinge pin 122 abuts against the lower surface of the lower protruding piece 121b, thereby restricting further upward movement. In this state, the upper end of the upper door-frame hinge pin 122 protrudes a predetermined amount above the upper surface of the upper protruding piece 121b.

[0207] In the door-frame-upper hinge assembly 120, when the horizontally extending portion of the lower end of the door-frame-upper hinge pin 122 is moved downward against the biasing force of the lock spring 124, the entire door-frame-upper hinge pin 122 can be moved downward, and the upper end of the door-frame-upper hinge pin 122 can be retracted below the upper surface of the upper protruding piece 121b. Therefore, in the door-frame-upper hinge assembly 120, the upper end of the door-frame-upper hinge pin 122 can be inserted from below into the door-frame upper hinge hole 511a of the main-frame-upper hinge member 510 and removed downward. As a result, by inserting the upper end of the door-frame-upper hinge pin 122 into the door-frame upper hinge hole 511a of the main-frame-upper hinge member 510, the upper left end of the door frame 3 in a front view can be supported so as to be hinge-rotatable relative to the main frame 4.

[0208] Furthermore, in the upper door-frame hinge assembly 120, the portion of the upper door-frame hinge pin 122 that extends vertically is positioned coaxially with a lower door-frame hinge pin 126 of a lower door-frame hinge member 125, which will be described later. This allows the upper door-frame hinge pin 122 and the lower door-frame hinge pin 126 to hinge rotate the door frame 3 relative to the main frame 4 in a favorable state.

[0209] [3-1g. Door frame bottom hinge material] The lower door frame hinge member 125 of the door frame base unit 100 will be described mainly with reference to Figures 34 and 35. The lower door frame hinge member 125 is attached to the lower left corner of the door frame reinforcement unit 110 when viewed from the front. The lower door frame hinge member 125 cooperates with the upper door frame hinge assembly 120 to attach the door frame 3 to the main frame 4 so that it can rotate about the hinge.

[0210] The door frame lower hinge member 125 is attached to the door frame reinforcement unit 110 and comprises a flat mounting piece 125a that is rectangular when viewed from the front, a flat protruding piece 125b that extends forward from the lower edge of the mounting piece 125a, and a door frame lower hinge pin 126 (see Figure 35, etc.) that protrudes downward from the underside near the front end of the protruding piece 125b.

[0211] The mounting piece 125a and the protruding piece 125b of the lower hinge member of the door frame 125 are formed by bending a metal plate. The lower hinge pin 126 of the door frame is a cylindrical 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 the 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 where it is assembled to the door frame base unit 100.

[0212] By inserting the lower hinge pin 126 of the 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.

[0213] [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, (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).

[0214] 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.

[0215] 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.

[0216] 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 rotatably attached at a position to the right of the rotation center of the first cam member 134 and the lower end 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 rotatably attached at a position below the rotation center of the first cam member 134 and the lower end rotatably attached at a position below the rotation center of the second cam member 135.

[0217] The cylinder lock 130 also includes a rear cover 138 attached to the cylinder mounting frame 115 so as to cover the cylinder 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 rivets 139 that attach the upper and lower ends of each of the first arm 136 and the second arm 137 to the first cam member 134 and the second cam member 135, respectively, so that they can rotate.

[0218] The first cam member 134 has an upper end side of a first arm 136 attached to the rear side, and an upper end side of a second arm 137 attached to the front side. The second cam member 135 is rotatably attached from the rear side by the cylinder mounting frame 115, and a rotation transmission member 133 is attached to the rear side across the front side of the cylinder mounting frame 115 so as to be rotatable integrally with the second cam member 134. The second cam member 135 has a lower end side of the first arm 136 attached to the front side, and a lower end side of the second arm 137 attached to the front side and forward of the first arm 136.

[0219] In each of first cam member 134 and second cam member 135, the portion where first arm 136 is attached and the portion where second arm 137 is attached are spaced apart at an angle of 90 degrees around the respective rotation axes. In addition, in each of first cam member 134 and second cam member 135, the portion where first arm 136 is attached is located farther from the center of rotation than the portion where second arm 137 is attached.

[0220] The rear cover 138 is removably attached to the cylinder mounting frame 115 at its upper end with screws (not shown), with the cylindrical shafts 138a protruding outward from the lower ends of both the left and right sides engaged with L-shaped locking slits 115b in the cylinder mounting frame 115.

[0221] In this cylinder lock 130, the cylinder mounting frame 115, the cylinder body 131, the rotation transmission member 133, the first cam member 134, the second cam member 135, the first arm 136, and the second arm 137 are made of metal.

[0222] When the cylinder lock 130 is assembled to the door frame 3, the front end of the cylinder body 131 is substantially aligned with the front end of the cylinder insertion opening 440b of the door frame right side unit 430.

[0223] Here, we will explain the conventional cylinder lock 130A. As shown in Figures 41(c) and (d), the conventional cylinder lock 130A has a cylinder body 131 that penetrates the front piece of the cylinder mounting frame 115A from the rear and has its rear end attached to the front piece. In this cylinder lock 130A, a rotation transmission member 133 is provided on the axis of the cylinder body 131.

[0224] Next, the operation of the cylinder lock 130 of this embodiment will be described. In a conventional cylinder lock 130, as shown in Figures 41(c) and (d), a rotation transmission member 133 is provided on the axis of the cylinder body 131, whereas in the cylinder lock 130 of this embodiment, as shown in Figures 41(a) and (b), the rotation transmission member 133 is provided at a position spaced downward from the axis of the cylinder body 131.

[0225] 43(a), in the normal state of this cylinder lock 130, both upper and lower ends of the first arm 136 are attached to the right of the rotation centers of the first cam member 134 and the second cam member 135, respectively, and both upper and lower ends of the second arm 137 are attached to the lower of the rotation centers of the first cam member 134 and the second cam member 135. With the use of a regular key, the cylinder body 131 can be rotated by 90 degrees both clockwise and counterclockwise from the normal state.

[0226] In this state, when the first cam member 134 is rotated counterclockwise via the cylinder of the cylinder body 131 using a key inserted in the keyhole 132, the first arm 136 and the second arm 137 move upward. At this time, because the upper end side of the first arm 136 is attached to the right of the rotation center of the first cam member 134, a large force acts from the first arm 136 to rotate the second cam member 135 counterclockwise, whereas because the upper end side of the second arm 137 is attached below the rotation center of the first cam member 134, almost no force acts from the second arm 137 to rotate the second cam member 135 counterclockwise.

[0227] In this way, when first cam member 134 rotates counterclockwise from the normal state, force is transmitted mainly via first arm 136, causing second cam member 135 to rotate counterclockwise, and rotation transmission member 133 to rotate together with second cam member 135. The upward force acting due to this counterclockwise rotation of first cam member 134 is proportional to the left-right distance between the positions where first arm 136 and second arm 137 are attached to first cam member 134 and the rotation center of first cam member 134. Therefore, as first cam member 134 rotates counterclockwise from the normal state, the upward force acting on first arm 136 decreases, while the upward force acting on second arm 137 increases.

[0228] Therefore, when first cam member 134 rotates counterclockwise beyond 45 degrees from the normal state, the force acting upward on second arm 137 becomes greater than that on first arm 136, and second cam member 135 rotates counterclockwise mainly via second arm 137. Then, the key inserted in keyhole 132 can be rotated counterclockwise up to an angle of 90 degrees from the normal state (see Figure 43(b)).

[0229] Note that when the key is rotated 90 degrees clockwise from the state where it is rotated 90 degrees counterclockwise from the normal state to return to the normal state, it will operate by the reverse action of the above.

[0230] On the other hand, when the key inserted into the keyhole 132 rotates the first cam member 134 clockwise through the cylinder of the cylinder body 131 from the normal state, the first arm 136 with the upper end attached to the right of the rotation center of the first cam member 134 moves downward, and the second arm 137 with the upper end 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 is attached to the right of the rotation center of the first cam member 134, a large force acts to rotate the second cam member 135 clockwise by the first arm 136. In contrast, in the second arm 137, since the upper end is attached below the rotation center of the first cam member 134, almost no force acts to rotate the second cam member 135 clockwise from the second arm 137.

[0231] In this way, when the first cam member 134 rotates clockwise from the normal state, the force is mainly transmitted through the first arm 136, the second cam member 135 rotates clockwise, and the rotation transmission member 133 rotates together with the second cam member 135. The force transmitted from the first cam member 134 to the second cam member 135 by the first arm 136 and the second arm 137 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 clockwise from the normal state, the force to rotate the second cam member 135 decreases in the first arm 136, while the force to rotate the second cam member 135 increases in the second arm 137.

[0232] Therefore, when the rotation angle of the first cam member 134 from the normal state in the clockwise direction exceeds 45 degrees, the second arm 137 has a greater force than the first arm 136 to rotate the second cam member 135, 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)).

[0233] 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 rotated 90 degrees in the clockwise direction to return to the normal state, it will operate by the reverse action of the above.

[0234] 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.

[0235] 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 a different position 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.

[0236] Furthermore, as described above, even if the position of the cylinder body 131 is changed in the door frame 3, there is no need to change the locking unit 650 in the body frame 4, so the locking unit 650 can be reused, thereby suppressing any increase in costs associated with the pachinko machine 1.

[0237] Incidentally, in the conventional cylinder lock 130A, the rotation transmission member 133 is provided at the rear of the cylinder body 131, so there is a risk that a fraudster who knows this configuration could insert a tool from the front to the rear of the cylinder body 131 and use the tool to fraudulently rotate the rotation transmission member 133, thereby opening the door frame 3 and committing fraud. In contrast, the cylinder lock 130 of this embodiment has the rotation transmission member 133 provided at a position away from the axis (rear) of the cylinder body 131. Therefore, even if a tool is inserted at the rear of the cylinder body 131 to rotate the rotation transmission member 133, the rotation transmission member 133 cannot be rotated because the rotation transmission member 133 is not present at that position, and fraudulent acts such as opening the door frame 3, the main body frame 4, etc. can be prevented.

[0238] Furthermore, in cylinder lock 130, second arm 137 connects portions of first arm 136 that are spaced apart by a rotation angle of 90 degrees on first cam member 134 and second cam member 135. Therefore, even if the portions of either first arm 136 or second arm 137 attached to first cam member 134 and second cam member 135 are positioned on a line connecting the center of first cam member 134 and the center of second cam member 135, the other of first arm 136 or second arm 137 connects the portions that are furthest from the line connecting the center of first cam member 134 and the center of second cam member 135. Therefore, even if one of first arm 136 or second arm 137 is positioned at the dead center of first cam member 134 and second cam member 135 and therefore cannot transmit the rotation from first cam member 134 to second cam member 135, the other of first arm 136 or second arm 137 can transmit the rotation from first cam member 134 to second cam member 135, so there is no significant resistance to the rotation of first cam member 134 and the key inserted in keyhole 132 can be rotated smoothly, making it easy to lock and unlock, and also preventing the key inserted in the keyhole from being forced to rotate, preventing damage to the key.

[0239] Furthermore, the rotation of the key inserted into the keyhole 132 is transmitted to the rotation transmission member 133, which is located at an eccentric position, by two arms, the first arm 136 and the second arm 137. Therefore, even if one arm is damaged for some reason, the rotation can be transmitted by the remaining arm, and a pachinko machine 1 having a highly reliable cylinder lock 130 can be provided.

[0240] Furthermore, the rotation of the key inserted into the keyhole 132 is transmitted to the rotation transmission member 133, which is located at an eccentric position, by the smooth rod-shaped (strip-shaped) first arm 136 and second arm 137. If the rotation were transmitted by a gear, there is a risk that the gear would rotate and rotate the rotation transmission member 133 by hooking the tip of a tool onto the gear teeth. However, by making the first arm 136 and the second arm 137 rod-shaped with a smooth surface, it is possible to make it difficult for the tip of a tool to become caught on the first arm 136 or the second arm 137, and it is possible to prevent the rotation transmission member 133 from being rotated by moving the first arm 136 or the second arm 137. This makes it possible to reliably prevent the locking unit 650 from being operated improperly and causing the door frame 3 or the main frame 4 to be unlocked.

[0241] In addition, in the cylinder lock 130 of this embodiment, the first arm 136 and the second arm 137 are used as a rotation transmission mechanism for transmitting the rotation of the first cam member 134 to the second cam member 135, but this is not limited to this and may be, for example, a rotation transmission mechanism using multiple 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.

[0242] [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 Figures 44 and 45. Figure 44(a) is a perspective view of the ball feeding unit of the door frame base unit as seen from the front, and (b) is a perspective view of the ball feeding unit as seen from the rear. Figure 45(a) is an exploded perspective view of the ball feeding unit as seen from the front, and (b) is an exploded perspective view of the ball feeding unit as seen from the rear with the rear case and anti-tamper member removed. The ball feeding unit 140 can feed game balls B supplied from the upper tray 201 of the tray unit 200 one by one to the ball launcher 540 of the main frame 4, and can also extract game balls B stored in the upper tray 201 to the lower tray 202 by operating the upper tray ball extraction button 222.

[0243] The ball feeding unit 140 comprises a box-shaped front cover 141 having an entrance 141a penetrating in the front-to-rear direction through which the game balls B are supplied from the upper tray 201 of the tray unit 200 and a ball ejection port 141b opening below the entrance 141a, and an open rear end; a rear cover 142 that closes the rear end of the front cover 141 and is box-shaped and has an open front end, and has a ball supply port 142a for supplying the game balls B that enter from the entrance 141a of the front cover 141 penetrating in the front-to-rear direction to the ball launching device 540; The rear cover 142 is provided with a ball removal member 143 rotatably supported around an axis extending in the front-to-back direction between the front cover 141 and the front cover 141, and having a partition 143a that separates the entrance 141a and the ball removal opening 141b at the rear of the front cover 141, a ball feeding member 144 that is rotatably supported around an axis extending in the up-down direction between the front cover 141 and the rear cover 142 and sends the game balls B on the partition 143a of the ball removal member 143 one by one to the ball supply opening 142a of the rear cover 142, and a ball feeding solenoid 145 that rotates the ball feeding member 144.

[0244] As shown in the figure, when viewed from the front, this ball feeding unit 140 has a ball feeding member 144 located to the right of the entrance 141a, a ball removal member 143 located to the left of the ball feeding member 144, and a ball feeding solenoid 145 located to the right of the ball feeding member 144.

[0245] The front cover 141 of the ball feeding unit 140 has an arc-shaped slit 141c formed concentrically with the center of rotation of the ball removal member 143 to the left of the ball removal opening 141b when viewed from the front, and the operating rod 143c of the ball removal member 143, which will be described later, extends forward from this slit 141c. In addition, the upper side of the front cover 141 extends upward from the upper edge of the entrance 141a, and is formed so that when the door frame 3 is assembled, the rear side closes the rear-open portion of the ball feeding guide path and ball removal guide path 241c of the rear base 241 in the upper tray ball removal unit 240.

[0246] The ball removal member 143 includes a partition portion 143a that partitions between the inlet 141a and the ball removal port 141b below the inlet 141a and has a partition upper surface that slopes downward toward the ball feeding member 144, a rotation paddle portion 143b that extends downward from an end of the partition portion 143a opposite to the ball feeding member 144 and is bent in a U shape from near the middle in the vertical direction toward the lower center of the ball removal port 141b and has a lower end extending in the front-rear direction and is rotatably supported around an axis, a rod-shaped operating paddle 143c that protrudes forward from the upper end of the rotation paddle portion 143b, and a weight portion 143d that protrudes from the side surface of the rotation paddle portion 143b below the operating paddle 143c to the side opposite to the partition portion 143a. The operating paddle 143c of the ball removal member 143 is formed to protrude forward through an arc-shaped 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 operation transmission portion 242b of an upper dish ball removal slider 242 that moves downward by pressing an upper dish ball removal button 222 of the dish unit 200 through a ball feeding opening 101e of the door frame base 101.

[0247] The ball feeding member 144 includes a blocking portion 144a that faces the inlet 141a and the partition portion 143a of the ball removal member 143 and extends in the vertical direction and has a fan-shaped view in plan around 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° around 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 around the rotation axis by moving the paddle portion 144c disposed at a position eccentric from the rotation axis in the left-right direction by driving a ball feeding solenoid 145.

[0248] 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 inside the ball holding portion 144b.

[0249] 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 in the vertical direction around the axis.

[0250] 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 around 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 so 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 drive 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 so 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.

[0251] 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 around an axis extending in the front-rear direction between the front cover 141 and the rear cover 142. The ball feeding crank 147 also 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.

[0252] 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 around an axis extending in the front-rear direction via the ball feeding actuating lever 146.

[0253] When the ball feeding unit 140 is not driven by the ball feeding solenoid 145 (in the normal state), the ball feeding operating rod 146 is separated from the lower end of the ball feeding solenoid 145 and the tip is positioned downward. In this state, the ball feeding member 144 is in the supply position. Also, 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.

[0254] Also, the ball feeding unit 140 is pivotally supported so that a moment is applied to the ball removal 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 removal member 143 abuts on the upper end of the operating transmission portion 242b of the upper plate ball removal slider 242 that operates by pressing the upper plate ball removal button 222 of the dish unit 200, its rotation is restricted. Therefore, in the normal state, the partition portion 143a of the ball removal member 143 is positioned between the inlet 141a and the ball removal port 141b to partition, and the game ball B does not enter the ball removal port 141b side.

[0255] 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.

[0256] Note that the upper plate ball extraction slider 242 on 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.

[0257] 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.

[0258] The anti-tampering member 148 is formed in a rectangular shape with an outer shape extending horizontally 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 within a predetermined distance from the right side to the left side, and inclined portions 148c that are each formed in a chamfered shape C at the tip sides of the sides of the upper piece portion 148a and the lower piece portion 148b that face each other (the right end side in a front view). The upper piece portion 148a of the anti-tampering member 148 is bent so that the right end in a 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.

[0259] 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.

[0260] According to this anti-tampering member 148, when an illegal game ball B with a string attached is driven into the game area 5a by the ball launcher 540 from the upper tray via the ball feeding unit 140, and an illegal act is performed such that the string attached to the illegal game ball B is operated to insert and remove the illegal game ball B from the first start port 2002 or the like, the string attached to the illegal game ball B is inserted between the upper piece portion 148a and the lower piece portion 148b by the momentum of the illegal game ball B launched (hit) by the ball launcher, and can be cut by the narrowed portion of the V-shaped groove 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.

[0261] [3-1j. Far Cover Unit] The foul cover unit 150 of the door frame base unit 100 will be described in detail mainly with reference to Figures 46 and 47. Figure 46(a) is a perspective view of the foul cover unit of the door frame base unit as seen from the front, and (b) is a perspective view of the foul cover unit as seen from the rear. Figure 47 is a front view of the foul cover unit with the cover member removed. The foul cover unit 150 is attached to the right side of the lower rear part of the door frame base 101 as seen from the rear. The foul cover unit 150 guides game balls B (foul balls) that are launched by the ball launching device 540 but do not reach the game area 5a of the game board 5 to the lower tray 202, and also guides game balls B paid out from the payout device 580 to the upper tray 201 or the lower tray 202. As shown in the figure, the fall cover unit 150 comprises a shallow box-shaped unit body 151 attached to the rear side of the door frame base 101 and open at the front, and a flat lid member 152 attached to the front of the unit body 151.

[0262] The fall cover unit 150 is equipped with a through ball passage 150a that penetrates from front to back at the upper left corner when viewed from the front and connects the lower normal dispensing passage 610a of the lower full ball path unit 610 of the main frame 4 with the upper tray ball supply port 211a of the tray unit 200, and a full ball receiving port 150b that opens toward the rear on the lower right side when viewed from the front of the through ball passage 150a and can connect with the lower full dispensing passage 610b of the lower full ball path unit 610 of the main frame 4.

[0263] The foul cover unit 150 also has a foul ball receiving port 150c that opens upward on the right side of the full ball receiving port 150b when viewed from the front and receives game balls B (foul balls) that have been launched by the ball launching device 540 of the main frame 4 but have not reached the game area 5a, and a ball discharge port 150d that opens forward near the lower right corner when viewed from the front and discharges game balls B received in the full ball receiving port 150b and the foul ball receiving port 150c forward, and is connected to the lower tray ball supply port 211c of the tray unit 200.

[0264] Furthermore, the peel cover unit 150 includes a storage passage 150e formed between the full ball receiving port 150b, the peel 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.

[0265] 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 peel 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.

[0266] In addition, the peel 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.

[0267] When the lower dish 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 dish 202 side, the peel 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 dish 202 is full of game balls B. Therefore, when the full detection sensor 154 detects fullness, the payout of further game balls B can be stopped, and this can be reported to the player, the staff of the game hall, etc., to prompt them to eliminate the fullness of the lower dish 202.

[0268] 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 projection 613a of the discharge passage opening / closing door 613 of the lower full ball path unit 610 in the discharge unit 560 (to be 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 projection 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.

[0269] [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 allows 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.

[0270] The glass unit 160 includes a frame-shaped glass frame 161 that can be attached to the glass unit attachment portion 101h and is larger than the inner peripheral shape of the door window 101a of the door frame base 101, 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.

[0271] 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 front and rear so that a space is formed between them.

[0272] 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 on the outer sides of the upper two corners among the four corners of the door window 101a on the rear surface of the door frame base 101, respectively.

[0273] 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 reinforcement 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. Thereafter, 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.

[0274] 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).

[0275] 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 from the door frame base 101.

[0276] [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 having an outer periphery formed in a predetermined shape, a flat rear protruding piece 172 protruding rearward 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.

[0277] The main body portion 171 of the security cover 170 is formed such that in a state of being attached to the door frame base unit 100, the lower end protrudes downward more than the lower end of the glass unit 160. Further, 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 in a state of being assembled to the pachinko machine 1. More 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 in a state of being assembled to the pachinko machine 1.

[0278] 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. Further, the rear protruding piece 172 also protrudes rearward 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 rearward from a part of the rear surface of the main body portion 171 is formed so as to be along a part of the outer rail 1001 in the front component 1000 of the game board 5 in a state of being assembled to the pachinko machine 1.

[0279] 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. As a result, 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.

[0280] 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). As a result, the security cover 170 can be easily attached to and detached from the door frame base unit 100.

[0281] When the security cover 170 is assembled to the pachinko machine 1, the front surface of the main body 171 abuts against the rear surface (the rear end of the glass frame 161) of the glass unit 160, and the rear protruding piece 172 except for 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. As a result, 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.

[0282] [3-4a. Handle Unit] Next, the handle unit 180 in the door frame 3 will be described in detail with reference to Figures 48 to 52. Figure 48 is an exploded perspective view of the handle unit, the tray unit, and the performance operation unit in the door frame as seen from the front, and Figure 49 is an exploded perspective view of the handle unit, the tray unit, and the performance operation unit in the door frame as seen from the rear. Figure 50 is an exploded perspective view of the handle unit in the door frame as seen from the front, and Figure 51 is an exploded perspective view of the handle unit in the door frame as seen from the rear. Figure 52(a) is an explanatory diagram showing a perspective view of the relationship between the handle base, handle, handle return spring, and handle touch sensor in the handle unit, and (b) is an explanatory diagram showing an exploded perspective view of (a). Figure 53 is an explanatory diagram showing a perspective view of the relationship between the handle base, handle, handle return spring, handle touch sensor, and inner base in the handle unit as seen from the rear. Note that in Figure 53, the position of the first mounting portion 190a in the handle return spring 190 has been changed for ease of understanding.

[0283] The handle unit 180 in this embodiment is attached to the door frame base unit 100 from the front within the cylindrical handle cover unit 290, and when operated by the player, the game ball B in the upper tray 201 can be shot into the game area 5a of the game board 5.

[0284] The handle unit 180 comprises a handle base 181 whose rear end is attached to the handle mounting surface of the door frame base 101, a handle 197 rotatably attached to the front end of the handle base 181, a disc-shaped cover base 183 attached to the handle base 181 so as to cover the center of the front end side of the handle 197, a handle decoration board 184 attached to the front side of the cover base 183 and having multiple LEDs 184a mounted on the front side, and a handle front lens 185 attached to the cover base 183 so as to cover the front side of the handle decoration board 184.

[0285] 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 thereof 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.

[0286] 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, which biases the handle 197 to return to the initial rotation position (the rotation end in the counterclockwise direction when viewed from the front), and an auxiliary spring 191 having one end attached to the inner base 186 and the other end attached to the transmission gear 188, which biases the detection shaft 189a of the handle rotation detection sensor 189 in the clockwise direction when viewed from the front via the transmission gear 188.

[0287] In addition, the handle unit 180 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 the 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.

[0288] 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 to be 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 becomes in a state where it cannot rotate relative to the handle cover base 291.

[0289] Further, the handle base 181 includes a sensor housing recess 181d that houses the handle touch sensor 192 therein from the front, a tab contact portion 181e against which the 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 the 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 in 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 the 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 (to be described later) in the handle 197, and a driver as a tool can be approached from the front through the slit 197e.

[0290] 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 around 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.

[0291] With the annular first attachment portion 190a provided at the front end of the handle return spring 190 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 the player.

[0292] 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.

[0293] 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 brought into 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, and even if the surface corrodes or oxidizes due to the generation of gas or the like from the chemical solution and adhering to the handle return spring 190 or the like, a contact failure does not occur, and the handle touch sensor 192 can surely detect the contact of the player.

[0294] 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.

[0295] This handle unit 180 is attached to the handle mounting seat surface of the door frame base 101 via a 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 rearward of 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, it is inclined so that its tip portion faces 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.

[0296] [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.

[0297] (Modified Example 1) In the above embodiment, it is shown that the tab-shaped terminal 192a of the handle touch sensor 192 and the second attachment portion 190b of the handle return spring 190 are 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 by increasing the contact portion as compared with point contact, the occurrence of poor contact can be prevented. In this case, it is desirable to provide the protrusion of the handle 197 at a portion where chemical solutions such as alcohol or sodium hypochlorite used for cleaning are less likely to be applied. Alternatively, a cover may be provided at the portion so that chemical solutions such as alcohol do not adhere.

[0298] (Modified Example 2) Also, for example, the configuration shown in FIG. 54 may be adopted. FIG. 54 is an explanatory diagram showing a perspective view 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, as viewed from the rear. 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.

[0299] 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 they are screwed together with mounting screws. 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. Thus, 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. So, 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.

[0300] 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 go around like a C shape may also be used.

[0301] 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.

[0302] (Modification Example 3) Alternatively, for example, the handle touch sensor 192 may 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-shaped 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. Also in this case, similar to the above, it is possible to surely prevent poor contact (detection failure of the handle touch sensor 192). Therefore, even when chemical solutions such as alcohol and sodium hypochlorite are used during cleaning in the game hall where the pachinko machine 1 is installed, poor contact does not occur, and the handle touch sensor 192 can surely 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.

[0303] (Modification Example 4) Alternatively, 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-shaped terminal 192a of the handle touch sensor 192 using a mounting screw, and the other round terminal 198a is screwed using a mounting screw 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. Also in this case, similar to the above, it is possible to surely prevent poor contact (detection failure of the handle touch sensor 192). Therefore, even when chemical solutions such as alcohol and sodium hypochlorite are used during cleaning in the game hall where the pachinko machine 1 is installed, poor contact does not occur, and the handle touch sensor 192 can surely detect the contact of the player.

[0304] (Other Modification Examples) In the above description, it is shown that a screw-fastening member is provided on the plating layer provided on the handle 197. However, the present invention is not limited thereto. For example, when a metal portion is provided on the handle 197, the metal portion may be screw-fastened to be electrically connected to the handle touch sensor 192. As the metal portion, for example, the above-described ring portion 197B may be made of metal.

[0305] In the above description, it is shown that the handle touch sensor 192 has tab-shaped terminals 192a. However, 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.

[0306] [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, a handle operated by a player to launch a game ball into a game area and a touch sensor for detecting that the player is touching the handle are provided (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 of the handle by the player. In this type of conventional gaming machine, in the spring for returning the handle, the end portion on the touch sensor side and the end portion on the handle side are brought into contact with each other using the biasing force of the spring.

[0307] Incidentally, in a game hall where gaming machines are installed, when cleaning and disinfecting the gaming machines, chemical solutions such as alcohol or sodium hypochlorite may be used. 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.

[0308] Therefore, in the following means, in view of the above situation, an object is to provide a gaming machine capable of reliably detecting contact with the handle by a player.

[0309] (Means for Solving Technical Features) Means 1: In a gaming machine, A gaming machine provided with a handle unit for firing game balls 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; One end side is screwed together with an electrode tab of the touch sensor, or the tip of a wire connected to the electrode tab or the connector of the touch sensor, and the other end side is in contact with a plated portion or a metal portion of the handle, and it is characterized by including a linear metal wire body.

[0310] Here, examples of the "wire body" include a "spring", a "wire", etc.

[0311] According to the configuration of means 1, a gaming machine is provided with 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, and an electrode tab of the touch sensor, or the tip of a 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 metal portion of the handle, and it includes a linear metal wire body. (Refer to the description in the chapter of [3-4a. Handle Unit] and FIGS. 50 to 54, etc. in [Mode for Carrying Out the Invention])

[0312] In this configuration, in the handle unit for launching a game ball into a game area, one end side of the metal wire body whose other end side is in contact with the plated portion or metal portion of the handle is screwed together with the electrode tab of the touch sensor provided on the handle base, or the tip of the 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 wire electrically connected to the touch sensor via the electrode tab or the connector. As a result, compared with the case where only the one end side of the wire body is simply brought into contact without screwing, even if 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, causing the surface to corrode or oxidize, 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.

[0313] In addition, when screwing the electrode tab of the touch sensor, it is desirable to attach the touch sensor to the handle base. This allows the attachment of one end side of the linear body and the attachment of the touch sensor to be performed simultaneously, reducing the labor involved in assembly and disassembly.

[0314] Also, the other end side of the linear body may be locked to the protruding portion protruding from the handle. As a result, 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) involved in the assembly and disassembly of the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0315] Furthermore, the other end side of the linear body may be screwed to the handle. 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 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.

[0316] 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 for each screw (mounting screw) at one end side and the other end side of the linear body. As a result, since the linear body can be screwed from the same direction at both ends, the labor involved in assembling the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0317] Also, it is desirable that the linear body be a spring that biases the handle around the axis. In this way, since the linear body that electrically connects the handle and the touch sensor is used as the spring that biases the handle, the number of components of the handle unit can be reduced compared to the case where the linear body is a member separate from the spring (for example, an electric wire), and an increase in the cost of the gaming machine can be suppressed.

[0318] 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.

[0319] Here, examples of the "protrusion" include "one integrally formed with the handle", "one insert-molded on 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.

[0320] 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 of the Invention])

[0321] 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 the assembly and disassembly of the handle unit can be reduced, and an increase in the cost of the gaming machine can be suppressed.

[0322] Note that, after locking the other end side of the linear body to the protrusion of the handle, it may be screwed. In this way, 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.

[0323] Means 3: In the configuration of Means Ⅰ or Means 2, "The other end side of the linear body is screwed to the handle." It is characterized by that.

[0324] 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 in [Mode for Carrying Out the Invention])

[0325] Thus, 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 or the like is corroded or oxidized by a chemical solution such as alcohol or sodium hypochlorite, poor contact will not occur, and the touch sensor can surely detect the player's contact with the handle through the linear body.

[0326] 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 with respect to each screw (mounting screw). Thereby, 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.

[0327] 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 its axis." It is characterized by that.

[0328] According to the configuration of means 4, the linear body is a spring that biases the handle around its axis. (Refer to the description of the handle return spring 190 in [Mode for Carrying Out the Invention])

[0329] Accordingly, since the linear body that electrically connects the handle and the touch sensor serves 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.

[0330] 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.

[0331] (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.

[0332] (Characteristic effects of the present embodiment) According to the pachinko machine 1 of the present 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 as 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-like 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-like 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, chemicals such as alcohol or sodium hypochlorite used during cleaning of the pachinko machine 1 do not enter the handle unit 180, or gas or the like is generated and adheres to the spring or the like, even if the surface corrodes or oxidizes, 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 the game ball B cannot be fired 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 the decline of the player's interest.

[0333] Also, when the tab-like 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, and the labor required for assembly and disassembly can be reduced.

[0334] 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 poor contact to occur not only on the one end side (the second attachment portion 190b side) but also on 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, poor contact will 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.

[0335] 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.

[0336] In addition, 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, compared with the case where the linear body is a separate member (for example, an electric wire) from the handle return spring 190, the number of parts of the handle unit 180 can be reduced, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0337] 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. As a result, 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.

[0338] [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. 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.

[0339] The handle cover base 291 has a cylindrical rear tube 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 protrusions that project inward from the inner periphery of the rear tube portion and extend back and forth and are provided at positions corresponding to the groove portions 181c of the handle base 181 in the circumferential direction.

[0340] The rear tube portion has its rear end attached to the handle mounting seat surface of the door frame base 101. This rear tube 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 protrusions 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.

[0341] 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 spindle-shaped (kamakura type, or bowl type, etc.) cylindrical shape 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.

[0342] The handle cover unit 290 of this embodiment can discharge liquid such as drinks and game balls B into the cylinder to the lower side of the handle cover unit 290 through the lower notch opening 295b even if they enter the cylinder.

[0343] Also, the lower notch opening 295b of the handle cover 295 is provided on the extension line in the inclination direction of the blade part 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 part 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 (a game ball B driving device), by vibrating the main body frame speaker 622 and sending wind into the front cylinder part 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 have the operation amount of the handle operation changed, thereby making the player enjoy the game and making it difficult for the player to get bored, and suppressing a decrease in the interest in the game.

[0344] 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 the interest in the game can be suppressed.

[0345] Also, as described above, for 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 different from the door frame 3 where the handle 197 and the handle cover unit 290 are provided is induced 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, it does not damage various sensors (handle rotation detection sensor 189, handle touch sensor 192, single-shot button operation sensor 194, etc.) and bearing mechanisms provided on the handle 197, etc., and it becomes possible to make the handle unit 180 difficult to be damaged, and it is possible to avoid giving discomfort to the player due to the damage of the handle unit 180, and it is possible to suppress the decrease in the player's interest in the game.

[0346] 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.

[0347] 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.

[0348] 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.

[0349] [3-5. Overall Configuration of Dish Unit] The dish unit 200 in the door frame 3 will be described in detail mainly with reference to FIGS. 48 and 49. The dish unit 200 is attached to a portion below the door window 101a on the front surface of the door frame base 101 of the door frame base unit 100. The dish unit 200 includes an upper dish 201 for storing the game balls B to be driven into the game area 5a, and a lower dish 202 disposed below the upper dish 201 and capable of storing the game balls B supplied from the upper dish 201 and the far cover unit 150.

[0350] The dish unit 200 includes a dish base unit 210 having an upper dish 201 and attached to the front surface of the door frame base 101 of the door frame base unit 100, a dish decoration unit 250 having a lower dish 202 and attached to the front surface of the dish base unit 210, and an effect operation unit 300 attached to the front surfaces of the dish decoration unit 250 and the dish base unit 210 and operable by a player.

[0351] The dish base unit 210 includes a flat plate-shaped dish unit base 211 extending horizontally, an upper dish body 212 attached to the upper front portion of the dish unit base 211 and having the upper dish 201, a mounting base (not shown) attached to the right side of the upper dish body 212 and protruding forward, a dish unit relay substrate (not shown) attached to the right side of the mounting base, a ball lending operation unit 220 attached to the upper surface of the mounting base, an upper dish ball extraction front unit (not shown) attached to the lower side of the mounting base, and an upper dish ball extraction rear unit 240 attached to the rear of the upper dish ball extraction front unit.

[0352] The dish decoration unit 250 includes a dish body 251 that is attached to the lower front of the dish unit base 211 and has a lower dish 202, a dish unit main body 252 that is attached to the front of the dish unit base 211 so as to cover the outer periphery of the dish body 251, a lower dish ball removal unit 260 that is attached to the lower surface of the dish body 251, and a left dish decoration unit 270 and a right dish decoration unit 275 that are respectively attached to the upper front of the dish unit main body 252 with a space therebetween in the left and right directions.

[0353] The effect operation unit 300 includes an effect operation part 301 operable by a player, a pressing operation part 303 that can be pressed by the player, a lever operation part 304 that allows the player to perform a lever operation in the front-rear direction, and the effect operation part 301 operable by the player. The effect operation unit 300 includes a base unit 400 attached to the dish base unit 210, and a lever operation unit 410 rotatably attached to the base unit 400 around an axis extending in the left-right direction. The pressing operation part 303 is provided on the upper surface of the base unit 400.

[0354] The dish unit 200 bulges forward as a whole, and the effect operation unit 300 is arranged such that the upper surface of the effect operation part 301 faces obliquely upward and forward at the center in the left-right direction. An upper dish 201 is arranged on the left side of the effect operation unit 300 on the upper surface, a ball lending operation unit 220 is arranged on the right side of the effect operation unit 300, and a lower dish 202 is arranged on the left side of the effect operation unit 300 below the upper dish 201.

[0355] [3-5a. Upper Dish] The upper tray 201 of the tray unit 200 will be described in detail, mainly with reference to Figures 48 and 49. The upper tray 201 is formed by a tray unit base 211 and an upper tray main body 212, and is formed like an upwardly open container, with the left side bulging forward more than the center when viewed from the front. The upper tray 201 (upper tray main body 212) bulges forward most from the left end to the right, approximately one-third of the width of the door frame 3. The front end of the upper tray 201 recedes backward from the most bulging part toward the right when viewed from the front, and has a guide passage portion 201a (see Figure 37) whose depth in the front-to-back direction is slightly larger than the outer diameter of the game ball B. The entire bottom surface of the upper tray 201, including the guide passage portion 201a, is inclined so that the right end is lower, and the right end of the guide passage portion 201a when viewed from the front is recessed below the ball dispensing operation unit 220.

[0356] When assembled to the tray unit 200, the upper tray 201 has a bottom surface that slopes downward from a position below the upper tray ball supply port 211a of the tray unit base 211 to a position slightly below the outer diameter of the game ball B relative to the upper end of the upper tray ball feed port (not shown). This allows the game ball B released forward from the upper tray ball supply port 211a to be received and stored within the upper tray 201, and the received game ball B can be supplied from the right end of the guide passage portion 201a through the upper tray ball feed port to the ball feed unit 140 side.

[0357] In addition, the guide passage section 201a is equipped with a metal earth fitting that is electrically grounded (earthed) in the pachinko machine 1, and when the game ball B comes into contact (rolls) with it, the static electricity charged to the game ball B can be removed.

[0358] [3-5b. Lower plate] The lower tray 202 of the tray unit 200 will be described in detail mainly with reference to FIG. 48 and the like. The lower tray 202 is disposed below the upper tray 201 and to the left of the center in the left-right direction of the tray unit 200 (door frame 3) when viewed from the front. The lower tray 202 is formed by a lower tray body 251 and a tray unit base 211. The lower tray 202 is formed in a container shape capable of storing the game balls B, and is provided with a lower tray ball discharge hole (refer to FIG. 29) 202a that penetrates vertically through the bottom wall and allows the game balls B to be discharged. The lower tray ball discharge hole 202a of the lower tray 202 is closably closed by a lower tray ball discharge lid of the lower tray ball discharge unit 260.

[0359] The lower tray 202 is formed in a substantially rectangular shape that extends 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 tray ball discharge hole 202a that penetrates vertically through the lower tray 202 is disposed near the front end near the right end. The bottom surface of this lower tray 202 is inclined so as to become lower toward the lower tray ball discharge hole 202a. The lower tray ball discharge hole 202a of the lower tray 202 is located to the left of and below the effect operation unit 300 in front of the lower tray ball supply port 211c in a state where it is assembled to the tray unit 200.

[0360] The lower tray 202 can store the game balls B discharged forward from the lower tray ball supply port 211c in a state where the lower tray ball discharge hole 202a is closed, and can discharge the stored game balls B below the tray unit 200 (for example, a dollar box) by opening the lower tray ball discharge hole 202a. Further, in a state where the lower tray ball discharge hole 202a of the lower tray 202 is open, since the lower tray ball discharge hole 202a is disposed in front of the lower tray ball supply port 211c, the game balls B discharged forward from the lower tray ball supply port 211c can be quickly discharged downward from the lower tray ball discharge hole 202a by moving the shortest distance.

[0361] [3-5c. Tray Base Unit] The dish base unit 210 in the dish unit 200 will be described in detail mainly with reference to FIGS. 48 and 49. The dish base unit 210 includes a flat plate-shaped dish unit base 211 that is attached to the lower front of the door frame base unit 100 and extends horizontally, an upper dish main body 212 that has an upper dish 201 and is attached to the upper front of the dish unit base 211, and a dish unit relay board 214 that is attached near the lower right corner on the rear surface of the dish unit base 211.

[0362] In addition, the dish base unit 210 includes a ball lending operation unit 220 that is attached to the upper part of the front surface of the dish unit base 211, an upper dish ball removal front unit (not shown) that is attached to the front surface of the dish unit base 211 below the ball lending operation unit 220, and an upper dish ball removal rear unit 240 that is attached to the rear side of the dish unit base 211 behind the upper dish ball removal front unit.

[0363] [3-5c-1. Dish Unit Base] The dish unit base 211 of the dish base unit 210 will be described in detail mainly with reference to FIGS. 48 and 49. The dish unit base 211 is attached below the door window 101a on the front surface of the door frame base 101 of the door frame base unit 100, and is formed in a flat plate shape (a shallow box shape with an open rear) that extends horizontally across the entire width of the door frame base 101.

[0364] The dish unit base 211 includes an upper dish ball supply port 211a that penetrates front and rear near the upper left corner in a front view and extends cylindrically rearward, a speaker port 211b that penetrates front and rear below the upper dish ball supply port 211a and has a punching metal attached to the front side, a lower dish ball supply port 211c that penetrates front and rear in the lower part to the left of the center in a front view and extends cylindrically rearward, a notch 211d that is cut out on the right side wall of the part that extends cylindrically rearward from the lower dish ball supply port 211c to a size that allows the game ball B to pass through, and an upper dish ball feeding port (not shown) that penetrates front and rear in the upper right side in a front view of the lower dish ball supply port 211c, extends vertically, and has its upper part located at the right end of the upper dish main body 212.

[0365] In the state where the upper plate ball supply port 211a of the dish unit base 211 is assembled to the door frame 3, the front end opens to the rear wall of the upper plate 201, and the cylindrical rear end penetrates the upper plate ball passage port 101g of the door frame base 101 from the front side and is connected to the front end of the through ball passage 150a of the far cover unit 150. Thus, the game ball B discharged from the payout device 580 of the payout unit 560 is supplied (payout) into the upper plate 201 through the upper plate ball supply port 211a.

[0366] In the state where the lower plate ball supply port 211c is assembled to the door frame 3, the front end opens to the rear wall of the lower plate 202, and the cylindrical rear end penetrates the lower plate ball passage port 101f of the door frame base 101 from the front side and is connected to the front end of the ball discharge port 150d of the far cover unit 150. Thus, the game ball B flowing through the storage passage 150e of the far cover unit 150 is supplied into the lower plate 202 through the lower plate ball supply port 211c. Further, the downstream end of the ball discharge guide path 241c in the rear base 241 of the upper plate ball removal rear unit 240 is connected to the notch 211d formed in the portion extending in the cylindrical shape of the lower plate ball supply port 211c. Thus, the game ball B stored in the upper plate 201 is discharged into the lower plate 202 from the lower plate ball supply port 211c through the upper plate ball removal button 222 operation, the upper plate ball supply port, the inlet 141a and the ball discharge port 141b of the ball supply unit 140, the ball supply guide path and the ball discharge guide path 241c of the upper plate ball removal rear unit 240, and the notch 211d.

[0367] The upper plate ball supply port is located in front of the ball receiving port (not shown in the figure) of the rear base 241 in the upper plate ball removal rear unit 240 in the state where it is assembled to the dish base unit 210, and the game ball B in the upper plate 201 is supplied from the ball receiving port of the upper plate ball removal rear unit 240 to the ball supply guide path.

[0368] [3-5c-2. Upper plate main body] The upper dish body 212 of the dish base unit 210 will be described in detail mainly with reference to FIGS. 48 and 49 and the like. The upper dish body 212 is attached to the front surface of the dish unit base 211 and forms the upper dish 201 in cooperation with the dish unit base 211. The upper dish body 212 is formed in a container shape (dish shape) with the upper and rear sides open. The upper dish body 212 extends horizontally, and when viewed from the front, the left side from the center of the left and right is larger and bulges forward. From the most forward-bulging part of the upper dish body 212 toward the right when viewed from the front, the front end retreats backward, and the depth in the front-rear direction is formed to have a width slightly larger than the outer diameter of the game ball B. The bottom surface of the upper dish body 212 is inclined so that the right end is the lowest. The upper part near the right end of the upper dish body 212 is closed.

[0369] In a state where the upper dish body 212 is assembled to the dish unit 200, the part where the upper part near the right end is closed is attached so as to dive under the ball lending operation unit 220.

[0377] [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 given mainly 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.

[0378] 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.

[0379] The rear base 241 protrudes upward from the portion where the upper plate ball removal slider 242 is slidably attached, 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 rearward, and a ball removal 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 rightward in a rear view.

[0380] 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 such that the inlet 141a of the ball feeding unit 140 is located at the lower rear in a state assembled to the door frame 3. 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.

[0381] The portion of the ball removal guide path 241c that extends left and right protrudes rightward in a rear view from the portion where the upper plate ball removal slider 242 is slidably attached, is inclined so that the right end side in a rear view is lower, and opens on the right side surface in a rear view. The portion of the ball removal guide path 241c that extends left and right is closed at the rear side by the rear cover 244. The ball removal guide path 241c is formed such that in a state assembled to the door frame 3, the upper part of the portion that extends vertically below the ball feeding guide path is located in front of the ball removal port 141b of the ball feeding unit 140, and the right end in a rear view of the portion that extends left and right is connected to the notch portion 211d of the lower plate ball supply port 211c in the dish unit base 211. As a result, the game ball B discharged from the ball removal port 141b of the ball feeding unit 140 is discharged into the lower plate 202 from the lower plate ball supply port 211c through the ball removal guide path 241c and the notch portion 211d.

[0382] The upper plate ball removal slider 242 is formed in a quadrangular shape when viewed from the front, and includes an operation receiving portion (not shown) protruding forward from the upper left corner and an operation transmission portion 242b protruding rearward from the rear surface on the rear side of the operation receiving portion. The upper surface of the operation receiving portion is formed flat. Further, the upper surface of the operation transmission portion 242b is inclined so as to be positioned downward as it goes rearward, and the lower surface extends horizontally so as to be connected to the rear end of the upper surface.

[0383] In the state where the upper plate ball removal slider 242 is assembled to the door frame 3, the operation receiving portion penetrates the plate unit base 211 from the rear side and protrudes forward, and the lower end of the upper plate ball removal button 222 abuts on the upper surface of the operation receiving portion. Further, in the state where the upper plate ball removal slider 242 is assembled to the door frame 3, the operation transmission portion 2 of the upper plate ball removal slider 242b protrudes rearward of the rear base 241, and the operation rod 143c of the ball removal member 143 of the ball feeding unit 140 abuts on the upper surface.

[0384] The spring has an upper end attached to the rear base 241 and a lower end attached to the upper plate ball removal slider 242, and biases the upper plate ball removal slider 242 upward. Therefore, the upper plate ball removal slider 242 is positioned at the upward movement end by the biasing force of the spring, and can move downward by resisting the biasing force of the spring.

[0385] Due to the biasing force of the spring, the upper plate ball removal slider 242 is positioned at the upward movement end, and the upper plate ball removal button 222 is positioned at the upward movement end through the operation receiving portion of the upper plate ball removal slider 242. Further, since the upper plate ball removal slider 242 is positioned at the upward movement end by the biasing force of the spring, the downward movement of the operation rod 143c abutting on the upper surface of the operation transmission portion 242b is blocked, and the partition portion 143a of the ball removal member 143 is positioned between the inlet 141a and the ball removal port 141b to partition between the two.

[0386] Therefore, when the upper plate ball removal button 222 is not pressed, the space between the inlet 141a and the ball removal port 141b in the ball feeding unit 140 is partitioned, and the game ball B sent from the upper plate 201 to the ball receiving port can be sent from the inlet 141a and through the ball feeding member 144 to the ball launching device 540 side from the ball supply port 142a.

[0387] On the other hand, when the upper plate ball removal button 222 is pressed downward against the biasing force of the spring, the upper plate ball removal slider 242 moves downward, and the operating lever 143c of the ball removal member 14b that is in contact with the upper surface of the operation transmission portion 242b of the upper plate ball removal slider 242 can move downward. Due to the load of the weight portion 143d of the ball removal member 143, the ball removal member 143 rotates and the partition portion 143a retreats from between the inlet 141a and the ball removal port 141b. As a result, the game ball B that has entered the inlet 141a from the upper plate 201 through the ball receiving port and the ball feeding guide path is discharged forward from the ball removal port 141b that is open below the inlet 141a. Then, the game ball B discharged forward from the ball removal port 141b is guided through the ball removal guide path 241c into the lower plate ball supply port 211c from the notch portion 211d, and then released from the lower plate ball supply port 211c into the lower plate 202, and the game ball B in the upper plate 201 is discharged into the lower plate 202.

[0388] When the downward pressing of the upper plate ball removal button 222 is released, the upper plate ball removal slider is moved upward by the biasing force of the spring, the upper plate ball removal button 222 rises, and the ball removal member 143 rotates by the operating lever 143c in contact with the operation transmission portion 242b, and the partition portion 143a is positioned between the inlet 141a and the ball removal port 141b and returns to the original state.

[0389] In this way, the upper plate ball removal unit 240 can feed the game ball B in the upper plate 201 to the ball launching device 540 side through the ball feeding unit 140 or discharge it to the lower plate 202 side.
