In the exposed portion, that is, the front surface of the game board 80, a game area PE in which game balls flow down is formed. As already described, the game area PE is covered with the glass panel 32. In the glass panel 32, the gap between the front surface of the game board 80 is slightly larger than the diameter of the game ball, that is, the game balls flowing down the game area PE are not lined up and down in the same place of the game area PE. Are arranged as follows. Thereby, the ball blockage in the game area PE is suppressed. Note that the game board 80 is not limited to wood, and may be made of a synthetic resin material, for example.

  Hereinafter, the game board 80 (in particular, various configurations arranged in the game area PE) will be described with reference to FIG. FIG. 6 is a front view of the game board 80.

  The game board 80 is formed with a plurality of large and small openings penetrating in its own thickness direction (front-rear direction) by performing router processing. Each opening is provided with a general winning port 81, a variable winning device 82, operating ports 83a and 83b, a through gate 84, a variable display unit 85, and the like. When game balls enter the general winning port 81, the variable winning device 82, and the operation ports 83a and 83b, the game balls are detected by a detection switch described later, and a predetermined number of award balls are paid out based on the detection result. The In addition, an out port 86 is provided at the lowermost part of the game board 80, and game balls that have not entered various winning ports etc. are discharged from the game area PE through the out port 86.

  In addition, in the game board 80, a number of nails 87 are implanted in order to disperse and adjust the flow path of the game ball as appropriate, and various members (functions) such as a windmill are arranged. The flow path of the game ball is differentiated by various configurations such as the nails 87 and the windmills, and adjusted so that the winning to the above-described general winning opening 81 and the like occurs with an appropriate establishment.

  The variable winning device 82 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which a game ball is easy to win in the case of a big hit. As a release mode of the variable winning device 82, a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winnings is regarded as one round, and the variable winning device 82 is opened by a plurality of rounds (for example, 15 rounds). It is set to be repeated as the upper limit.

  The variable display unit 85 is disposed at the upper center of the game board 80, and the operation ports 83a and 83b are disposed below the variable display unit 85. More specifically, the operation ports 83a and 83b are arranged side by side with the operation port 83a on the upper side and the operation port 83b on the lower side. The variable display unit 85 and the operation ports 83a and 83b are portions that control game play, and the player's attention is likely to be gathered. By arranging the variable display unit 85 and the operation ports 83a and 83b side by side in the center of the gaming machine, the movement amount of the line of sight between the two is suppressed, which contributes to the reduction of the burden on the player's eyes.

  The variable display unit 85 includes a symbol display device 94 that variably displays symbols with a winning in the operation ports 83a and 83b as a trigger. The symbol display device 94 is configured as a liquid crystal display device including a liquid crystal display (display screen 94a), and the display content is controlled by a display control device described later. Specifically, on the display screen 94a, symbols are displayed side by side in the upper, middle, and lower levels, and these symbols are variably displayed as they are scrolled in the horizontal direction. When a big hit occurs, a predetermined combination of symbols is stopped and displayed on a preset active line, and a transition is made to a special gaming state. The display mode on the display screen 94a may be changed as follows. That is, the symbols may be displayed side by side on the left, middle, and right, and the symbols may be displayed in a variable manner by scrolling up and down.

  The variable display unit 85 includes a center frame 95 formed so as to surround the symbol display device 94. A first specific lamp unit 96 and a second specific lamp unit 97 are provided on the center frame 95. Reservation lamp portions 98 and 99 are provided at the upper and lower portions of the center frame 95, respectively. The lower holding lamp unit 98 corresponds to the symbol display device 94 and the first specific lamp unit 96, and the number of times that the game ball has passed through the operation port 83 is held up to four times, and the holding lamp unit 98 is turned on. The number of reserved items is displayed. The upper holding lamp unit 99 corresponds to the second specific lamp unit 97, and the number of times that the game ball has passed through the through gate 84 is held up to four times, and the number of holdings is displayed by lighting the holding lamp unit 99. It has become so.

  Referring again to FIG. 5, below the game board housing portion 73 (game board 80) in the resin base 70, a game ball that launches a game ball to the game area PE based on the operation of the game ball launch handle 29. A firing mechanism 110 is provided. The game ball launching mechanism 110 includes a solenoid 111 that launches a game ball placed at a predetermined launch standby position, a launch rail 112 that defines the launch direction of the game ball launched by the solenoid 111, and a game at the launch standby position. A ball feeding device 113 for supplying a ball and a base plate 114 to which these various configurations 111 to 113 are mounted are provided as main components, and the base plate 114 is screwed to the resin base 70 to be internally It is integrated with the frame 13.

  The firing rail 112 is fixed to the base plate 114 in an inclined state so as to be inclined upward toward the game board 80 side. A ball stopper 115 that holds the game ball supplied from the ball feeding device 113 at the above-described firing standby position is disposed at a position closer to the downstream end portion (that is, the lower end portion) of the firing rail 112. The solenoid 111 is disposed at a position further downstream than the ball stopper 115.

  The solenoid 111 is electrically connected to a power source / launch control device described later. Based on the output of the electrical signal from the power supply / launch control device, the output shaft of the solenoid 111 reciprocates in the expansion / contraction direction, so that the game ball placed at the launch standby position is on the game board 80 side, more specifically, the game. It is driven out toward the guide rail 100 mounted on the board 80.

  The guide rail 100 forms a game area PE together with a game area partition member 108 to be described later so that the outer shape of the game area PE is substantially circular. In addition, the guide rail 100 includes an inner rail 101 and an outer rail 102 arranged so as to face each other with a gap slightly larger than the diameter of the game ball, and a single guide passage 103 is defined by both the rails 101 and 102. Is formed. The guide passage 103 includes an inlet portion 104 that is opened to the tip side (obliquely downward) of the firing rail 112, and an outlet portion 105 that is located above the gaming area PE. The game ball fired based on the operation of the solenoid 111 is guided to the game area PE by moving in the order of the firing rail 112 → the guide rail 100 (the entrance portion 104 → the exit portion 105). In the game board 80, a reversal prevention member 106 for preventing the reversal of the game ball reaching the game area PE into the guide passage 103 is attached to the front side of the exit portion 105, specifically near the tip of the inner rail 101. Thus, it is possible to prevent the subsequent launch of the game ball from being hindered by the game ball that has reached the game area PE first.

  Each of the rails 101 and 102 constituting the guide rail 100 has an arc shape centered at a substantially central portion of the game area PE. For this reason, the game ball passing through the guide passage 103 is likely to move (slide or roll) along the outer rail 102, that is, in contact with the outer rail 102 due to the centrifugal force generated by itself.

  As shown in FIG. 5, the guide rail 100 and the launch rail 112 are arranged so that the entrance portion 104 of the guide rail 100 and the tip portion of the launch rail 112 face each other diagonally across the lower edge of the game board 80. Has been. That is, both the rails 100 and 112 are arranged such that the entrance portion 104 of the guide rail 100 and the tip portion of the firing rail 112 are shifted left and right in the vicinity of the lower end edge of the game board 80. Thus, a gap of a predetermined interval is formed between the entrance portion 104 of the guide rail 100 and the firing rail 112 while bringing both rails 100 and 112 close to the lower end edge of the game board 80.

  A foul ball passage 55 is disposed below the gap formed in this way. The foul ball passage 55 is formed integrally with the passage forming unit 50 of the front door 14. If the game balls launched from the game ball launching mechanism 110 do not reach the game area PE and return as foul balls in the guide passage 103, the foul balls enter the foul ball passage 55 through the gap. It becomes. The foul ball passage 55 communicates with the front door side lower tray passage 52, and the game balls that have entered the foul ball passage 55 are discharged to the lower tray 28a shown in FIG. This suppresses interference between the foul ball and the next game ball to be launched.

  The resin base 70 has a plurality of lock devices 79 that can be switched between a locked state in which the game board 80 cannot be removed from the game board housing portion 73 and an unlocked state in which the game board 80 is allowed to be removed. Is provided. The locking device 79 has an abutting portion that abuts against the front surface of the game board 80 in the locked state, and the abutting portion abuts against the front surface of the game board 80, thereby moving the game board 80 toward the front door 14. The displacement will be suppressed.

  On the left side of the firing rail 112 in the resin base 70 (specifically, the side supporting the front door 14), a passage forming member 121 is disposed in a through hole that penetrates the resin base 70 in the front-rear direction. The passage forming member 121 is screwed to the resin base 70 and has a main body side upper dish path 122 and a main body side lower dish path 123. The upstream side of the main body side upper dish passage 122 and the main body side lower dish passage 123 communicates with a game ball distributing section described later. A receiving portion 53 of a passage forming unit 50 attached to the front door 14 is inserted below the passage forming member 121, and a front door side upper plate passage 51 is disposed below the main body side upper plate passage 122. The front door side upper dish passage 51 is disposed below the main body side lower dish passage 123 (see FIG. 5).

  In the resin base 70, below the passage forming member 121, a shutter 124 that restricts the outflow of game balls from the main body side upper dish path 122 and the main body side lower dish path 123 is provided. The shutter 124 is supported by the resin base 70 in a state where the shutter 124 can be switched between a blocking position where the exit portions of both passages are narrowed to prevent the gaming ball from flowing out and an allowable position where the gaming ball is allowed to flow out. Further, a biasing member that biases the shutter 124 toward the blocking position is attached to the resin base 70. When the front door 14 is opened with respect to the inner frame 13, the shutter 124 is biased by the biasing force of the biasing member. Is configured to remain in the blocking position. Thereby, when the front door 14 is opened in a state where the game balls are stored in the main body side upper tray passage 122 or the main body side lower tray passage 123, the disadvantage that the stored balls spill out is avoided. In contrast, when the front door 14 is closed, the shutter 124 is pushed back to the allowable position against the urging force by the receiving portion 53 provided in the passage forming unit 50 of the front door 14. In this state, the main body side upper tray passage 122 and the front door side upper tray passage 51 communicate with the main body side lower tray passage 123 and the front door side lower tray passage 52, respectively, and the movement of the game ball is permitted. Become.

  Next, the back configuration of the inner frame 13 (the resin base 70 and the game board 80) will be described with reference to FIG. FIG. 7 is a rear view of the inner frame 13.

  A bearing fitting 132 is attached to the rotation base end side (the right side in FIG. 7) on the back surface of the resin base 70.

Here, the configuration of the back surface of the game board 80 will be described in detail with reference to FIG. FIG. 8 is a perspective view of the game board 80 as seen from the rear.

  On the back of the game board 80, a base member 141 made of synthetic resin for mounting the variable display unit 85 on the game board 80 is fixed. The pedestal member 141 has a substantially box shape opened to the game board 80 side, and covers almost the entire rear surface of the game board 80. A part of the base member 141 protrudes to the back side of the resin base 70 through the central opening 74 of the resin base 70, and the symbol display device 94 described above and the symbol display device 94 are driven with respect to the protruding portion. And a display control device for mounting. The symbol display device 94 and the display control device are arranged so that the symbol display device is on the front side and the display control device is on the rear side in the front-rear direction (thickness direction of the resin base 70). Furthermore, the game board 80 is equipped with an audio lamp control device unit 142 so as to be positioned behind the display control device. The sound lamp control device unit 142 includes a sound lamp control device 143 and a mounting table 144, and the sound lamp control device 143 is mounted on the mounting table 144.

  The sound lamp control device 143 includes a sound lamp control board that controls sound, lamp display, and display control device in accordance with instructions from a main control device to be described later, and the sound lamp control board is made of a transparent resin material or the like. It is configured to be accommodated in a substrate box 145.

  A main controller unit 160 is provided below the sound lamp controller unit 142 so as to cover the base member 141 from behind. The main controller unit 160 includes a synthetic resin mounting base 161 fixed to the back of the game board 80 and a main control unit 162 mounted on the mounting base 161. The main controller 162 includes a main control board having a function (main control circuit) that controls the main control of the game and a function (power failure monitoring circuit) that monitors the power source, and the main control board is made of a transparent resin material. It is configured to be accommodated in a substrate box 163 made of, for example.

  The board box 163 includes a substantially rectangular parallelepiped box base (front case body) and a box cover (back case body) that covers an opening of the box base. The box base and the box cover are connected so as not to be unsealed by a box sealing portion 164 as sealing means, whereby the substrate box 163 is sealed. A plurality of box sealing portions 164 are provided on the short side portion of the substrate box 163, and at least one of them is used for sealing processing.

  Any configuration can be applied to the box sealing portion 164 as long as the box base and the box cover are coupled so as not to be opened. However, by inserting a locking pin into the locking hole that forms the box sealing portion 164, the box sealing portion 164 can be applied. The base and the box cover are coupled so as not to be opened. The sealing process by the box sealing unit 164 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. Even after opening, the sealing process can be performed again. That is, the sealing process is performed by inserting a locking pin into at least one locking hole portion among the plurality of box sealing portions 164. When the substrate box 163 is opened, such as when a failure occurs in the accommodated main control board or when the main control board is inspected, a connecting portion between the box sealing portion into which the locking pin is inserted and the substrate box 163 main body. Disconnect. As a result, the box base and the box cover of the substrate box 163 are separated, and the internal main control substrate can be taken out. Thereafter, when the sealing process is performed again, a locking pin is inserted into another locking hole. If the history of opening the substrate box 163 is left in the substrate box 163, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 163.

  The board box 163 and the mounting base 161 are connected by a base seal part 165 so that they cannot be opened. Specifically, the pedestal sealing portion 165 has a locking hole portion and a locking pin similarly to the box sealing portion 164, and the locking pin is inserted into the locking hole portion so that the board box 163 and The mounting base 161 is coupled so as not to be separable. This makes it easier to grasp the fact that the substrate box 163 has been illegally removed.

  The portion of the pedestal member 141 that faces the back of the game board 80 corresponds to the game board openings of the general winning port 81, variable winning device 82, upper operating port 83a, and lower operating port 83b, and on the downstream side. A collection passage that collects in one place is formed. Thereby, all the game balls won in the general winning opening 81 and the like are gathered below the game board 80 through the collection passage. That is, the pedestal member 141 is provided with a function of collecting game balls won in various winning openings.

  A discharge passage, which will be described later, is arranged below the game board 80, and the game balls gathered below the game board 80 by the collection passage are led out into the discharge passage. Similarly, the out port 86 leads to the discharge passage, and a game ball that has not won any winning port is led out into the discharge passage through the out port 86.

  Further, in the collection passage, a winning port switch for detecting a game ball won in the general winning port 81 on the front side of the game board 80, a count switch for detecting a game ball won in the variable winning device 82, and an operation port 83a, An operating port switch for detecting a game ball entering 83b is mounted, and a winning detection mechanism is constituted by these various switches. Furthermore, gate switches for detecting game balls passing through the through gate 84 are provided on the left and right sides of the variable display unit 85 in the base member 141. These various switches are electrically connected to the main control device 162, and the detection information by each switch is output to the main control device 162.

  Next, the back pack unit 15 will be described with reference to FIGS. FIG. 9 is a rear view of the pachinko machine 10, and FIG. 10 is a front view of the back pack unit 15.

  As shown in FIG. 9, the inner frame 13 is covered from behind by the back pack unit 15. The back pack unit 15 includes a back pack 201, and a payout mechanism unit 202, a discharge passage board, and a control device assembly unit 204 are attached to the back pack 201.

  The back pack 201 is formed of a synthetic resin having transparency, and as shown in FIG. 10, a base portion 211 to which a payout mechanism portion 202 and the like are attached, and a protective cover portion 212 that protrudes rearward from the pachinko machine 10 and has a substantially rectangular parallelepiped shape. And have. The protective cover 212 has a shape in which the left and right side surfaces and the upper surface are closed and only the lower surface is opened, and has a size sufficient to surround at least the variable display unit 85 (see FIG. 9).

  The base part 211 is provided with an external terminal board (not shown) at the upper right part thereof. Various output terminals are provided on the external terminal plate, and various signals are output to the management control device on the game hall side through these output terminals. Further, the base portion 211 is provided with a pair of upper and lower latch pins 214 at the right end when viewed from the rear of the pachinko machine 10, and the latch pins 214 are inserted through the bearing portions 133 provided on the inner frame 13. The back pack unit 15 is supported so as to be rotatable with respect to the inner frame 13. The base portion 211 is formed with a plurality of insertion portions 215 through which the fixing levers 134 provided in the inner frame 13 are inserted, and the base portion 211 is rearward of the base portion 211 in a state where the fixing levers 134 are inserted through the insertion portions 215. The back pack unit 15 is fixed to the inner frame 13 by contact with the inner frame 13.

  In the base portion 211, a payout mechanism portion 202 is disposed so as to bypass the protective cover portion 212. The payout mechanism 202 is provided with a tank 221 that is arranged at the top of the back pack 201 and that opens upward, and game balls supplied from the island facilities of the game hall are sequentially replenished to the tank 221. The A tank rail 222 that is gently inclined toward the downstream side is connected to the lower side of the tank 221, and a case rail 223 that extends in the vertical direction is connected to the downstream side of the tank rail 222. A payout device 224 is provided at the most downstream portion of the case rail 223. The game balls paid out from the payout device 224 are supplied to the game ball distribution unit 225 provided in the base portion 211 of the back pack 201 through a payout passage (not shown) provided on the downstream side of the payout device 224.

  The game ball distribution unit 225 has a function of distributing the game balls paid out from the payout device 224 to any one of the upper plate 27a, the lower plate 28a, and a discharge passage described later, and the inner opening is the main body described above. The upper dish passage 122 and the front door side upper dish passage 51 lead to the upper dish 27a, and the outer opening communicates with the main body side lower dish passage 123 and the front door side lower dish passage 52 to the lower dish 28a. (See FIGS. 7 and 14).

  At the lower end portion of the base portion 211, the discharge passage board and the control device collective unit 204 are attached so as to sandwich the lower end portion in the front-rear direction. In the discharge passage board, a discharge passage opened rearward is formed on a surface facing the control device assembly unit 204, and an open portion of the discharge passage is closed by the control device assembly unit 204. The discharge passage is formed so as to discharge the game ball to the island facility or the like of the game hall, and the game ball led to the discharge passage from the recovery passage described above passes through the discharge passage to the outside of the pachinko machine 10. Discharged.

  As shown in FIG. 10, the control device assembly unit 204 has a horizontally long mounting base 241, and a payout control device 242 and a power supply / launch control device 243 are mounted on the mounting base 241. The payout control device 242 and the power supply / launch control device 243 are arranged so as to overlap each other so that the payout control device 242 is behind the pachinko machine 10.

  In the payout control device 242, a payout control board for controlling the payout device 224 is accommodated in the board box 244, and a state return switch 245 provided on the payout control board projects out of the board box 244. For example, when the state return switch 245 is pressed when a payout error occurs, such as a ball jam in the payout device 224, the ball jam is eliminated.

  The power source / launch control device 243 includes a power source / launch control board housed in the board box 246, and a predetermined power source required for various control devices and the like is generated and output by the board. Control of the launch of the game ball accompanying the operation of the firing handle 29 is performed. Further, the power supply / launch control device 243 is provided with a RAM erase switch 247. This pachinko machine 10 has a function to store and store various data so that even if a power failure occurs, it maintains the state at the time of the power failure, and when it recovers from the power failure, it can be restored to the state at the time of the power failure. It has become. Therefore, for example, when the power supply is turned off in the normal procedure, as in the case of the game hall being closed, the state before the interruption is stored and held, but when the power is turned on while the RAM erase switch 247 is pressed, the RAM data is initialized. It is like that.

(Mounting structure of game board 80)
Here, the mounting structure of the game board 80 will be described based on FIG. 5, FIG. 11 and FIG. 11 is a perspective view showing a state in which the game board 80 is removed from the inner frame 13, and FIG. 12 is a partial cross-sectional view taken along line AA of FIG.

  As already described, the game board 80 is fitted from the front side of the inner frame 13 with respect to the game board housing portion 73 of the inner frame 13 (see FIG. 5). As shown in FIG. 11, the game board housing part 73 includes a flat counter plate part 251 that faces the back of the game board 80, and a peripheral wall part that stands up from the counter plate part 251 and extends along the periphery of the game board 80. 261. The counter plate portion 251 has the above-described central opening 74 formed at substantially the center thereof, and has a substantially rectangular frame shape when the inner frame 13 is viewed from the front. The peripheral wall portion 261 is composed of an upper side wall portion 262, a lower side wall portion 263, a left side wall portion 264, and a right side wall portion 265 that are individually opposed to the upper, lower, left and right end surfaces of the gaming board 80, and the gaming board 80 as a whole. An annular shape surrounding the It can be said that the peripheral wall portion 261 is formed so as to surround the central opening 74.

  A plurality of stopper portions 271 that suppress the forward displacement of the game board 80 are provided on the left side wall portion 264 of the inner frame 13, that is, the wall portion 264 on the side supporting the front door 14. Each stopper portion 271 protrudes from the inner wall surface of the left side wall portion 264 to the game board housing portion 73 side, and comes into contact with the game board 80 (a second rail cover 400 described in detail later) from the front of the pachinko machine 10. ing. Moreover, each stopper part 271 is accommodated in the game board accommodating part 73, and the protrusion to the front door 14 side is suppressed.

  These stopper portions 271 are arranged at positions near the upper end and the lower end of the game board 80, so that the displacement of the game board 80 can be suppressed in a well-balanced manner. If it supplements regarding arrangement | positioning of the stopper part 271, the stopper part 271U near upper end is arrange | positioned above the part which protrudes in the rotation base end side of the game board 80 in the said guide rail 100, and is located near lower end. The stopper portion 271L is disposed below the convex portion. Accordingly, the stopper portion 271 and the guide rail 100 are preferably allowed to coexist on the front side of the game board 80, and the compression of the game area PE due to the adoption of the stopper portion 271 is suppressed.

  A metal plate member 281 is disposed on the inner frame 13 along the leading edge of the left wall portion 264. The plate member 281 has a long shape extending across both the upper frame portion 13 a and the lower frame portion 13 b of the inner frame 13, and both end portions of the plate member 281 are the left frame portion of the inner frame 13. In addition to being fixed (screwed) to 13c, an intermediate portion of the plate member 281 is fixed (screwed) to the stopper portion 271 described above. Thereby, the part connected with the outer frame 11 and the front door 14 in the inner frame 13 is reinforced, and also the deformation | transformation of the stopper part 271 is suppressed.

  The stopper portion 271 and the counter plate portion 251 described in detail above constitute an insertion portion 290 into which one side portion of the game board 80 can be inserted (see FIG. 12). The insertion portion 290 is located on the rotation base end side of the front door 14, and the inner frame 13 allows the insertion of the game board 80 from the side opposite to the side supporting the front door 14 in the inner frame 13. 13 is open to the rotation tip side (right side wall 265 side). In particular, the gap dimension between the stopper portion 271 and the opposing plate portion 251 (specifically, the portion excluding ribs described later) is set larger than the thickness dimension of the game board 80. Thus, the game board 80 can be inserted into the insertion portion 290 from obliquely forward, and the game board 80 inserted into the insertion portion 290 can be rotated around the insertion portion 290. Further, by turning the insertion port of the insertion portion 290 obliquely forward, the game board 80 can be extended to the rearward projecting portion of the front door 14 or the right frame portion 13d (see FIG. 11) of the inner frame 13 when the game board is inserted. Interference is suppressed.

  In addition, the chamfering is given to the site | part facing the game board 80 in the front-end | tip part of the stopper part 271, and the entrance part of the insertion part 290 is expanded. Thereby, the said gap dimension is enlarged and the catching of the stopper part 271 and the game board 80 at the time of inserting the game board 80 diagonally is suppressed.

  Below the insertion portion 290 (the stopper portion 271 group), specifically, at a position where the left wall portion 264 and the lower wall portion 263 intersect in the inner frame 13 (see FIG. 11), the game board 80 inserted into the insertion portion 290 is placed. A temporary placement portion 125 that can be temporarily placed is provided. The temporary placement portion 125 is formed in the passage forming member 121 and has a surface shape facing the insertion portion 290 side (upward). The temporary placement portion 125 is not necessarily formed in the passage forming member 121 and can be formed in the resin base 70.

  The temporary placement portion 125 is located above the lower wall portion 263 of the game board housing portion 73 and faces the lower end portion of the game board 80. On the other hand, a notch portion 88 corresponding to the temporary placement portion 125 is formed in the lower corner portion of the rotation base end side of the game board 80 (see FIG. 6). When the game board 80 is inserted into the insertion part 290 and rotated, the cutout part 88 of the game board 80 is temporarily placed (temporarily placed) with respect to the temporary placement part 125, so At least a part of the weight of 80 is supported by the resin base 70 of the inner frame 13. As a result, the work load when the game board 80 is mounted is reduced, and the rotation operation of the game board 80 is facilitated.

  In addition, the temporary placement portion 125 extends to the opening side of the insertion portion 290 from the insertion portion 290. Thus, the game board 80 can be temporarily placed before being inserted into the insertion portion 290, which contributes to further facilitation of work.

  When the game board 80 is attached or detached, work is performed from the front side of the inner frame 13. At this time, it goes without saying that the operation is performed in a state where the front door 14 is opened. Here, the positional relationship between the opened front door 14, the game board 80, and the insertion portion 290 will be supplemented with the description based on FIG. FIG. 13 is a schematic diagram showing the positional relationship between the opened front door 14, the game board 80 and the insertion portion 290.

  As shown in FIG. 13, the front door 14 is pivotally supported by the support fittings 71 and 72 provided on the inner frame 13, and the pivotally supported portion (rotation center axis CL) is the center. It is configured to be opened and closed. The support fitting 72 is formed with a defining portion 72 a that defines the maximum opening position of the front door 14. When the front door 14 is opened and hits against the defining portion 72a, further opening is impossible. In the present embodiment, the maximum opening amount of the front door 14 is set to about 100 °. This is because when the front door 14 is opened in a state where the pachinko machine 10 is installed in an island facility such as a hall, the front door 14 does not interfere with other adjacent gaming machines and the like. Thus, it is a device for preventing a game in an adjacent gaming machine from being hindered. The maximum opening amount of the front door 14 is not limited to 100 °. It may be set arbitrarily as long as it is within a range that allows at least the game board 80 to be attached and detached.

  The rotation center axis CL of the front door 14 is located near the front surface of the front door 14, and the rotation base end portion of the front door 14 is fitted inside the inner frame 13 with the front door 14 closed. It becomes the structure which gets stuck. As a result, the inconvenience that an unauthorized tool is inserted through the boundary portion between the front door 14 and the inner frame 13 (particularly, the boundary portion on the rotation base end side of the front door 14) is less likely to occur, and the security function is enhanced. I am trying.

  The insertion portion 290 is disposed behind the rotation center axis CL. Since the front door 14 has a predetermined thickness, even when the front door 14 is opened to the maximum open position as described above, a part of the rear surface is on the right side of the insertion portion 290 (supporting the front door 14). It is in a state of overhanging on the side opposite to the side where it is present. Although the insertion portion 290 exists at a position deeper than the overhanging portion, when the game board 80 is put in and out, interference between the track PL through which the game board 80 passes and the front door 14 is avoided. The orientation of the insertion slot is determined. Thereby, interference with the overhang | projection part of the front door 14 at the time of mounting | wearing the game board 80 and the game board 80 is suppressed.

(Configuration related to protection of guide rail 100)
However, even if the orientation of the insertion port of the insertion portion 290 is devised as described above, it is possible to reduce the chance of occurrence of the interference, but this may result in variations in the insertion direction of the game board 80 or insufficient opening of the front door 14. It is assumed that it is difficult to completely eliminate the resulting interference. That is, it is considered difficult to suppress the occurrence of interference due to work variations only by means such as an insertion slot. Furthermore, since the game board 80 is detachable, the game board 80 may be hit when the game board 80 is transported, and the protection function of the game board 80 has room for improvement.

  In particular, the guide rail 100 that divides the game area PE is not only protruding from the front surface of the game board 80 but also located on the insertion portion 290 side in the game board 80. Compared to various configurations such as the enclosed nail 87, it is assumed that the object of interference is likely to occur. In addition, the guide rail 100 has an arc shape that is open on the opposite side of the insertion portion 290, that is, on the rotating front end side of the game board 80. A block-shaped game area partitioning member 108 that partitions the area PE is provided. In other words, the guide rail 100 and the game area partitioning member 108 form an annular shape by arranging the former on the rotation base end side of the game board 80 and the latter on the rotation front end side of the game board 80. Yes. Since the guide rail 100 is thus arranged on the rotation base end side, it is assumed that the guide rail 100 is likely to cause the interference even when compared with the game area partition member 108.

  As described above, the guide rail 100 has a function of guiding the game ball launched from the game ball launching mechanism 110 to the game area PE. For this reason, when deformation or the like due to the above-described interference occurs in the guide rail 100, it is assumed that the influence on the movement of the game ball is greater than when similar deformation occurs in the game area partition member 108. The Therefore, in the present embodiment, the guide rail 100 is protected from the interference and the like by covering the guide rail 100 from the outside of the game area PE with the first rail cover 350 and the second rail cover 400. .

  The first rail cover 350 and the second rail cover 400 are formed separately from the game board 80 using a synthetic resin material having transparency, and as shown in FIG. The game board 80 is fixed to the game board 80 in a protruding state. More specifically, both rail covers 350 and 400 are located on the front surface of the game board 80 and outside the game area PE, more specifically, the end of the game board 80 on the insertion portion 290 side and the guide rail 100 (specifically, the outer rail 102). ) Between the first rail cover 350 and the inlet portion 104 of the guide rail 100.

  As shown in FIG. 6, the first rail cover 350 has a flat plate-like base portion 360 that faces the front surface of the game board 80 (specifically, contacts the surface). The base portion 360 extends along the outer rail 102 from the entrance portion 104 of the guide rail 100 to a position in front of the top portion 102a of the portion protruding from the insertion portion side (left side) in the outer rail 102. The base portion 360 is integrally formed with a standing portion 370 that stands on the same side as the outer rail 102 from the base portion 360 (that is, in front of the pachinko machine 10). The standing portion 370 has a wall shape facing the outer rail 102 from the opposite side to the game area PE, and the front end edge of the rising portion 370 is formed to protrude forward from the front end edge of the outer rail 102. ing. The upright portion 270 covers the outer rail 102, that is, the portion constituting the guide passage 103 from the insertion portion 290 side.

  The second rail cover 400 is disposed at a position closer to the exit portion 105 of the guide rail 100 than the first rail cover 350. With the first rail cover 350 and the second rail cover 400, almost the entire area of the guide passage 103 is disposed. Is covered from the front side in the insertion direction of the game board 80.

  Hereinafter, the second rail cover 400 will be described in detail with reference to FIGS. 14 and 15. 14 is a partially enlarged view of FIG. 6, and FIG. 15 is a perspective view showing the configuration of the second rail cover 400. For convenience, the inner frame 13 is shown using a two-dot chain line in FIG. 14, and the game board 80 is shown using a two-dot chain line in FIG.

  As shown in FIG. 14, the second rail cover 400 is an area outside the game area PE on the front surface of the game board 80, more specifically, an end on the insertion part 290 side of the game board 80 and the guide rail 100 (more specifically, the outer Rail 102), and has a vertically long shape extending along the same end.

  Similar to the first rail cover 350, the second rail cover 400 includes a flat plate-like base portion 410 that faces the front surface of the game board 80 (specifically, contacts the surface). The base portion 410 extends vertically along the edge of the game board 80, and the upper end of the base portion 410 is higher than the top portion 102 a of the portion of the outer rail 102 that protrudes toward the insertion portion (left side). And the lower end of the base part 410 is formed so as to be located below the top part 102a. The central portion of the edge of the base portion 410 on the outer rail 102 side is curved along the outer rail 102, and the edge opposite to the outer rail 102 is straight along the edge of the game board 80. It extends in a shape. That is, the base portion 410 is bundled so that the width becomes narrow at the center portion in the longitudinal direction of the base portion 410 (see FIG. 15).

  The base portion 410 is integrally formed with a standing portion 420 that stands on the same side as the outer rail 102 from the base portion 410 (that is, in front of the pachinko machine 10). The upright portion 420 has a wall shape facing the outer rail 102 from the side opposite to the game area PE, and the front end edge of the upright portion 420 is formed to protrude forward from the front end edge of the outer rail 102. ing. By this standing portion 420, a portion of the outer rail 102 that protrudes toward the insertion portion 290, that is, a portion that constitutes the guide passage 103 is covered from the insertion portion 290 side.

  The upright portion 420 has a curved portion 421 formed along the curved portion of the base portion 410. The curved portion 421 is configured to be parallel to the outer rail 102 and ensure a slight gap between the curved portion 421 and the outer rail 102. Further, the upright portion 420 extends upward from the upper end of the bending portion 421 and extends downward from the lower end of the bending portion 421. Hereinafter, for the sake of convenience, a portion of the standing portion 420 that is above the curved portion 421 is referred to as an “upper standing portion 422”, and a portion that is below the curved portion 421 is referred to as a “lower standing portion 423”.

  The upper erected portion 422 and the lower erected portion 423 have a flat plate shape extending vertically, and are formed so that a gap with the outer rail 102 increases as the distance from the top portion 102a increases. In accordance with the expansion of the gap, the base portion 410 extends to the outer rail 102 side from the standing portion 420. That is, the curved portion 421 is formed along the edge of the base portion 410 on the outer rail 102 side, whereas the upper upright portion 422 and the lower upright portion 423 are approximately at the center in the width direction of the base portion 410. It is formed to be located. For the sake of convenience, a portion of the base portion 410 that is closer to the outer rail 102 than the upright portion 420 is referred to as “inner base portion 411”, and a portion of the base portion 410 that is closer to the insertion portion 290 is referred to as “outer base portion 412”.

  As shown in FIG. 13, screw holes 413 and 414 constituting fixing means for the second rail cover 400 are formed in the inner base portion 411 and the outer base portion 412. The screws 416 and 417 (see FIG. 14) inserted through the screw holes 413 and 414 are screwed to the game board 80, whereby the second rail cover 400 and the game board 80 are integrated.

  In FIG. 14, the second rail cover 400 has screw holes 414 and screws 417 provided in the outer base part 412 closer to the curved part 421 than screw holes 413 and screws 416 provided in the inner base part 411. Are shifted in the longitudinal direction (vertical direction). This is a device for improving the fixing strength of the second rail cover 400 in a limited space.

  An arm portion 430 that protrudes toward the insertion portion 290 is formed at an end portion (upper end portion) of the upper upright portion 422 opposite to the bending portion 421. The arm portion 430 is opposed to the upper surface 272 of the stopper portion 271 with a slight gap therebetween, and a protrusion 431 that protrudes toward the stopper portion 271 is formed on the facing portion. Corresponding to the protrusion 431, a receiving portion 275 that is recessed downward is formed on the upper surface 272 of the stopper portion 271, and the protrusion 431 is caught by the receiving portion 275.

  In the portion of the protrusion 431 facing the insertion portion 290 side, an inclined surface 432 is formed which is inclined downward from the tip portion of the arm portion 430 toward the root portion, and when the game board 80 is inserted into the insertion portion 290. In this case, the inclined surface 432 hits the boundary portion between the upper surface 272 and the side surface 273 of the stopper portion 271. Thereby, the arm portion 430 is bent and deformed with the base portion (portion connected to the upper upright portion 422) as the base end, and the protrusion 431 is guided to the upper surface 272 of the stopper portion 271. Thereafter, the arm portion 430 is returned to the state before the deformation by the elastic force, so that the protrusion 431 is caught by the receiving portion 275. In this way, the protrusion 431 is hooked on the receiving portion 275, so that the game board 80 is prevented from dropping from the insertion portion 290.

  As already described, in a state in which the protrusion 431 is hooked on the receiving portion 275, the game board 80 is placed on the temporary placement portion 125 on the rotation tip side from the hooking position of the protrusion 431 and the receiving portion 275. Yes. In other words, the game board 80 is prevented from falling off while the game board 80 is supported by the temporary placement unit 125. Thereby, it is suitably avoided that the load due to the weight of the game board 80 or the like is concentrated on the protrusion 431 and the receiving portion 275.

  Here, the relationship between the second rail cover 400 and the insertion portion 290 will be supplementarily described with reference to FIGS. 12 and 14. As shown in FIG. 14, in a state where the game board 80 is mounted on the inner frame 13, the insertion portion 290 (specifically, the stopper portion 271) has the upper standing portion 422 and the lower standing portion 423 of the second rail cover 400. The outer base portion 412 of the second rail cover 400 is fitted to the insertion portion 290.

  The outer base portion 412 is in contact with the back surface 274 of the stopper portion 271 from the back of the pachinko machine 10. A protruding portion 440 that protrudes on the side opposite to the standing portion 420 (on the game board 80 side) is integrally formed at a portion of the outer base portion 412 that is in contact with the stopper portion 271. The protrusion 440 has a cylindrical shape extending in the thickness direction of the game board 80, and the game board 80 is formed with a fitting hole 89 into which the protrusion 440 is fitted. The fitting hole 89 is open to the front side and the back side of the game board 80, and the leading end portion of the protruding portion 440 protrudes to the back side of the game board 80 through the fitting hole 89.

  The protruding portion 440 is provided with a distribution function for distributing the load applied to the second rail cover 400 (specifically, the standing portion 420) to the game board 80 through the protruding portion 440. To prevent the load from being concentrated. In particular, the protruding portion 440 has a vertically long shape extending in the longitudinal direction of the second rail cover 400, so that a load that causes an inclination with respect to the standing portion 420 with the root portion of the rising portion 420 as a base end is generated. When added, such a load can be suitably distributed.

  As shown in FIG. 12, a portion of the opposing plate portion 251 of the inner frame 13 that is closer to the turning tip of the game board 80 than the stopper portion 271, specifically, an edge portion on the central opening 74 side, The rib erected is formed, and the protrusion 440 is in contact with the rib. In this manner, the tip of the protruding portion 440 abuts against the rib of the opposing plate portion 251, so that the displacement of the game board 80 toward the back side of the game board housing portion 73 is restricted.

  Particularly in the present embodiment, the front-rear width dimension of the insertion portion 290 is set to be slightly smaller than the thickness dimension of the game board 80, specifically, the front-rear dimension from the front surface of the base portion 410 to the tip of the protruding portion 440. In a state where the game board 80 is arranged at the mounting completion position, the game board 80 is in a state of strong interference with the insertion portion 290. In this way, by causing the game board 80 to strongly interfere with the insertion portion 290, it is possible to suppress variations in the front and rear positions of the game board 80.

  However, when adopting such a configuration, it is not preferable that the insertion of the game board 80 into the insertion portion 290 becomes difficult. Therefore, as described above, the contact portion between the protruding portion 440 of the second rail cover 400 and the rib of the counter plate portion 251 is more than the contact portion between the base portion 410 and the stopper portion 271 of the second rail cover 400. By adopting a configuration that is positioned on the rotating front end side of the game board 80, it is possible to favorably suppress position variation in a state where the game board 80 is disposed at the mounting completion position while facilitating insertion of the game board 80. Yes.

(Configuration related to gap expansion regulation)
Particularly in the present embodiment, when the front door 14 is closed in a state where the game board 80 is mounted, that is, in a state where the front and rear positions of the game board 80 are defined by the stopper portion 271 and the locking device 79. Further, one of the features is that a restriction mechanism for restricting the expansion of the gap between the game board 80 and the glass unit 30 (specifically, the glass panel 32) is provided. Hereinafter, the restriction mechanism will be described in detail with reference to FIGS. 12, 13, 16, and 17. FIG. 16 is a schematic view showing the positional relationship between the second rail cover 400 and the glass unit 30, and FIG. 17 is a partial cross-sectional view taken along line BB in FIG. In FIG. 16, a part of the glass unit 30 is represented using a two-dot chain line and dot hatching for convenience. Moreover, in FIG. 17, the structure regarding the front door 14 is also displayed for convenience.

  As shown in FIG. 12, the curved portion 421 of the standing portion 420 is formed with a facing portion 450 that protrudes from the front end edge toward the outer rail 102 and faces the game board 80 with the outer rail 102 interposed therebetween. Yes. The facing part 450 is formed so as to straddle the upper standing part 422 and the lower standing part 423, and is provided with a reinforcing function of the bending part 421.

  As shown in FIG. 16, the facing portion 450 includes a first facing portion 451 disposed near the center of the bending portion 421 and second facing portions 452 and 453 disposed near both standing portions 422 and 423. doing. More specifically, as shown in FIG. 13, the facing portion 450 is formed in a stepped shape such that the first facing portion 451 is on the game board 80 side and the second facing portions 452 and 453 are on the front door 14 side.

  As shown in FIG. 17, the first facing portion 451 is opposed to the front end edge of the outer rail 102 with a slight gap, and the second facing portions 452 and 453 are opposed to the front end edge of the outer rail 102. And facing each other with a gap larger than that of the first facing portion 451. A part of the front door 14 is fitted in the gap between the outer rail 102 and the second facing portion 452.

  More specifically, as already described, the glass holder 33 of the front door 14 has an annular shape formed along the outer peripheral edge of the game board 80, and is disposed in front of the game board 80. The frame 34 of the glass holder 33 is separated from the glass unit installation unit 22 so that the edge of the frame 34 on the game board 80 side is closer to the front surface of the game board 80 than the facing part 450 of the second rail cover 400. Projecting to the game board 80 side. An extending portion 39 extending toward the second rail cover 400 is formed at a portion of the frame portion 34 that faces the second rail cover 400 from the game area PE side.

  The extending portion 39 has a flat plate shape extending from the outer wall surface of the frame portion 34 toward the curved portion 421 of the second rail cover 400, and at least a tip portion thereof is a gap between the second facing portion 452 and the outer rail 102. It fits in. The plate surface of the extending portion 39 is orthogonal to the juxtaposed direction (front-rear direction) of the game board 80 and the glass unit 30, and is behind the pachinko machine 10 with a slight gap with respect to the second facing portion 452. Opposite from. Further, the plate surface of the extension portion 39 is positioned on a virtual plane substantially the same as the plate surface on the rear side of the rear glass panel 32. That is, the extension part 39 and the rear glass panel 32 are formed to be substantially flush with each other. It is also possible to adopt a configuration in which the extending portion 39 abuts against the second facing portion 452 from the rear of the pachinko machine 10.

  When at least one of the glass unit 30 and the game board 80 is displaced to the side away from the other, the extending portion 39 comes into contact with the second facing portion 452, and the glass unit 30 (specifically, the rear glass panel 32). And expansion of the gap between the game board 80 and the game board 80 are restricted. In particular, the distal end portion of the extending portion 39 is curved so as to follow the curved portion 421, and is devised so that the allowance for the second facing portions 452 and 453 is as large as possible.

  In this Embodiment, the characteristic structure regarding the attachment structure of the glass unit 30 is employ | adopted together with the structure regarding the clearance gap control mentioned above. Here, the attachment structure of the glass unit 30 is demonstrated based on FIG. FIG. 18 is a partial cross-sectional view showing a structure for attaching the glass unit 30 to the frame body 20.

  As shown in FIG. 18, the frame body 20 of the front door 14 is provided with a holding portion 57 that holds the glass unit 30 (specifically, the attachment portion 35). The holding portion 57 has a cylindrical shape that protrudes toward the inner frame 13, and the mounting portion 35 is formed with an insertion portion 41 into which the holding portion 57 is inserted. More specifically, the central axis of the holding portion 57 extends in the front-rear direction, and the insertion portion 41 has a bottomed round hole shape extending in the same direction as the holding portion 57. When the holding portion 57 is fitted to the insertion portion 41, the movement of the glass unit 30 in the front-rear direction, that is, the sliding movement in the same direction as the parallel arrangement direction of the front door 14 and the inner frame 13 is allowed.

  Further, a through hole 42 is formed in a portion of the attachment portion 35 that forms the bottom of the insertion portion 41. A screw 45 is inserted into the through hole 42, and a tip end portion of the screw 45 inserted through the through hole 42 is screwed into a screw hole 58 formed in the holding portion 57.

  The head 45a of the screw 45 is opposed to the mounting portion 35 with a gap from the inner frame 13 side, and the head unit 45a prevents the glass unit 30 from falling off the frame body 20. In this way, the screw 45 can also be referred to as a “stopper 45” when attention is paid to the fact that the screw 45 has a function of preventing the glass unit 30 from dropping off from the frame body 20.

  A coil spring 46 as “biasing means” is inserted through the screw 45. The coil spring 46 is sandwiched and compressed between the head 45a and the attachment portion 35, and the attachment portion 35 is urged toward the frame 20 (ie, forward in the pachinko machine 10) by the coil spring 46. Yes. That is, the glass unit 30 is biased toward the front side of the game board 80 by the coil spring 46.

  A spring recess 43 into which the coil spring 46 is fitted is formed in a portion of the mounting portion 35 facing the head 45a. When the glass unit 30 slides backward, the coil spring 46 is compressed and fitted into the spring recess 43, so that the head 45a of the screw 45 comes into contact with the mounting portion 35 from the rear. That is, the slide stroke amount L1 of the glass unit 30 is defined by the gap between the mounting portion 35 and the head 45a of the screw 45.

  Here, with reference to FIG. 17 again, the description of the relationship between the glass unit 30 and the glass unit installation part 22 will be supplemented. As already described, the glass unit installation part 22 has a concave shape, and the glass unit 30 is fitted to the glass unit installation part 22 from the rear. The glass unit 30 includes a substantially annular peripheral wall portion 22 a constituting the glass unit installation portion 22, specifically, a peripheral wall portion 22 a that stands on the inner frame 13 side and that surrounds the window portion 21, and the glass unit 30. The overlap margin L2 in the direction orthogonal to the 30 slide directions is set to be larger than the slide stroke amount L1. Thereby, even if it is a case where the glass unit 30 is contact | abutting to the head 45a of the screw | thread 45, the overlap with the glass unit 30 and the glass unit installation part 22 (specifically peripheral wall part 22a) will be ensured. .

  As described above in detail, when the configuration allowing the slide movement of the glass unit 30 is adopted, the glass unit 30 slides and is arranged in the glass panel 32 of the glass unit 30 and the game area PE of the game board 80. It is not preferable that various components such as the nail 87 interfere with each other. Therefore, in the present embodiment, various contrivances are provided for avoiding such inconvenience. Hereinafter, an example will be described.

  As shown in FIG. 18, the plate member 281 fixed to the inner frame 13 is formed with a contact portion 282 that comes into contact with the mounting portion 35 from the game board 80 side when the front door 14 is closed. Yes. When the abutting portion 282 abuts against the attachment portion 35, the sliding movement of the glass unit 30 toward the game board 80 is prevented. Thereby, the clearance gap between the various structures provided in game area PE and the glass panel 32 is maintained, and generation | occurrence | production of the said interference etc. is suppressed. A plurality of configurations corresponding to the contact portion 282 are provided along the outer periphery of the glass unit 30. As for the contact portion 282, the attachment portion 35 is the contact target, but is not limited to this. Although a detailed description is omitted, the contact object of the other contact part is a part other than the attachment part 35 (for example, the frame part 34).

  As described in detail above, the position of the glass panel 32 and the game board 80 can be obtained by using the structure for restricting the gap between the glass unit 30 and the game board 80 and the structure for allowing the glass unit 30 to slide. The relationship can be suitably maintained, and further improvement of the crime prevention function is expected. Here, the positional relationship between the glass unit 30 and the game board 80 when the positional relationship between the front door 14 and the inner frame 13 changes due to external factors will be described with reference to FIG. FIG. 19 is a schematic diagram showing the positional relationship between the game board 80 and the glass unit 30.

  In the state where the front door 14 is closed with respect to the inner frame 13 as shown in FIG. 19A, the glass unit 30 extends to the facing portion 450 of the game board 80 (specifically, the second rail cover 400). The parts 39 are opposed to each other with a slight gap. In this state, the glass unit 30 stands by at the position closest to the front (close to the frame body 20) in the slide range by the urging force of the coil spring 46.

  As shown in FIGS. 19A to 19B, when a fraudulent tool T such as a bar is inserted in the boundary portion between the inner frame 13 and the front door 14 and the boundary portion is pushed and expanded in the front-rear direction. The front door 14 is lifted from the inner frame 13, and the gap between the inner frame 13 and the front door 14 is partially expanded. In this case, as shown in FIG. 19 (b), the extension part 39 abuts against the facing part 450 from the rear, so that the movement of the glass unit 30 following the frame body 20 of the front door 14 is prevented. Specifically, the relative position between the glass unit 30 and the frame body 20 is changed by compressing the coil spring 46 (see FIG. 18). That is, even if the frame body 20 is lifted from the inner frame 13, the glass unit 30 remains substantially in the original position. Thereby, the positional relationship between the game board 80 (specifically, the front surface thereof) and the glass panel 32 is suitably maintained.

  Further, even when the frame 20 is lifted from the inner frame 13, the glass unit 30 is not detached from the glass unit installation portion 22 as shown in the partially enlarged view of FIG. Thus, the overlap between the peripheral wall portion 22 a constituting the glass unit 22 and the glass unit 30 is maintained. Therefore, it is possible to prevent the gap between the frame body 20 and the glass unit 30 from expanding due to a change in the relative position between the frame body 20 and the glass unit 30. Therefore, it is possible to suppress the easy insertion of an unauthorized tool or the like through the window 21 → the same boundary.

  Here, the arrangement of the facing portion 450 will be supplementarily described. As described above, in the configuration in which the front door 14 is supported by the support fittings 71 and 72 disposed near the upper end portion and the lower end portion of the front door 14, an improvement in the rotational stability of the front door 14 is expected. On the other hand, it is assumed that the boundary portion between the front door 14 and the inner frame 13 is likely to expand at a portion between the support brackets 71 and 72. In this regard, the second facing portion 452 in the present embodiment is disposed between the support fittings 71 and 72, and the above restriction function is suitably exhibited.

  Further, at least one of the second facing portions 452 on the lower side is disposed between an end portion of the inner frame 13 that supports the front door 14 and the operation port 83. Thereby, the expansion of the gap in the vicinity of the operating port 83 can be suitably suppressed.

(Flow of game board 80 replacement work)
Hereinafter, the flow of the exchange work of the game board 80 will be described with reference to FIGS. 20 to 21 are perspective views schematically showing a state in which the game board 80 is exchanged. For convenience, the front door 14 is indicated by a two-dot chain line in FIGS. 20A and 21A, and the front door 14 is omitted in the other drawings.

  When removing the game board 80 from the pachinko machine 10, after opening the front door 14 as shown in FIG. 20 (a), the lock device 79 is switched to the unlocked state. As a result, the game board 80 is allowed to rotate.

  After the game board 80 becomes rotatable, as shown in FIG. 20A → FIG. 20B, the game board 80 is rotated to the near side with the insertion portion 290 as the center. At this time, it is not necessary to support the game board 80 by hand because the game board 80 can be rotated while being placed on the temporary placement part 125. Further, the projection 431 of the game board 80 is maintained in a state of being caught by the receiving part 275 of the resin base 70, and the game board 80 is prevented from dropping off from the insertion part 290. That is, even if the game board 80 is rotated to a predetermined position, it is caught and maintained.

  Next, as shown in FIG. 20 (b) → FIG. 20 (c), the game board 80 is lifted upward by holding it by hand. As a result, the game board 80 is separated from the temporary placement portion 125, and the game board 80 is supported by the operator. Then, based on this operation, the protrusion 431 is detached from the receiving portion 275, and the hook is released. Thereby, the operation of pulling out the game board 80 from the insertion portion 290 is allowed.

  Thereafter, as shown in FIG. 20 (c) → FIG. 20 (d), the removal of the game board 80 is completed by moving the game board 80 to the opening side of the insertion portion 290.

  When mounting the game board 80, work is performed in the order of FIG. 21 (a) → FIG. 21 (b) → FIG. 21 (c) → FIG. 21 (d) → FIG. 22 (e) → FIG. Is called.

  First, as shown in FIG. 21A, the front door 14 is rotated to the maximum open position. Thereafter, as shown in FIG. 2B, the game board 80 is held and the game board 80 (specifically, the cutout portion 88) is placed on the temporary placement portion 125. Thereby, the game board 80 is supported by the resin base 70, and at least a part of the weight of the game board 80 can be deposited on the resin base 70 side, and the subsequent work can be facilitated.

  When the game board 80 is pushed toward the insertion portion 290 while being placed on the temporary placement portion 125 as shown in FIG. 21 (b) → FIG. 21 (c), specifically, the same game with the notch 88 as a fulcrum. When the upper end of the board 80 is tilted toward the insertion part 290, a part of the game board 80 is fitted into the insertion part 290, and then the protrusion 431 (specifically, the inclined surface 432) of the second rail cover 400 is the upper surface of the stopper part 271. It hits the boundary between 272 and side surface 273.

  When the game board 80 is further pushed toward the back side of the insertion portion 290 from the state where the inclined surface 432 is in contact with the stopper portion 271 as described above, the arm portion 430 is bent and deformed, and the protrusion 431 is formed on the stopper portion 271. It is guided to the receiving part 275. Then, the protrusion 431 is hooked on the receiving portion 275, so that the game board 80 is prevented from dropping from the insertion portion 290. As described above, in a state in which the game board 80 is prevented from falling off, the weight of the game board 80 is supported by the resin base 70, and the operator does not need to support the game board 80.

  After that, as shown in FIG. 21 (c) → FIG. 21 (d), the game board 80 is accommodated in the game board accommodation part 73 by rotating the game board 80 with the insertion part 290 as the base end. After the game board 80 is accommodated in the game board accommodating portion 73, the lock device 79 is switched to the locked state, whereby the mounting operation of the game board 80 on the resin base 70 is completed.

  After the mounting of the game board 80 is completed, the extended portion 39 of the glass unit 30 is connected to the second rail cover 400 by closing the front door 14 as shown in FIG. 22 (e) → FIG. 22 (f). The extended portion 39 is inserted between the outer rail 102 and the second opposed portion 452 from the rear. Thereby, the expansion of the gap between the game board 80 and the glass unit 30 (specifically, the rear glass panel 32) is restricted.

Based on various commands output from the main control circuit 802, various lamp units 23 to 25, speakers The unit 26 and the display control device 825 are controlled. The display control device 825 controls the symbol display device 94 based on a display command input from the sound lamp control board 824.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  By making the game board 80 detachable from the front side of the inner frame 13, it is possible to facilitate the work compared to a configuration in which the game board is attached and detached from the rear side of the inner frame. Assuming a configuration in which the game board is attached / detached from the back side of the inner frame, it is necessary to attach / detach the game board with the inner frame opened. In this case, for example, by holding the movement of the inner frame by hand so that the inner frame does not move, the game board can be mounted smoothly. However, the work can be complicated when the inner frame is pressed by hand for the purpose of facilitating the work of attaching and detaching the game board. In this regard, as shown in the above embodiment, if the game board 80 can be attached and detached while the inner frame 13 is closed with respect to the outer frame 11, the inner frame 13 can be moved by a pushing operation or the like. Can be avoided. This eliminates the need for preliminary work such as pressing the inner frame 13 by hand when attaching or detaching the game board 80, and can contribute to facilitating the work. Since the opening / closing operation of the back pack unit 15 can be omitted, the work procedure can be simplified.

  When the game board 80 is mounted, the game board 80 can be rotated while being placed on the temporary placement portion 125 of the inner frame 13. That is, since at least a part of the weight of the game board 80 can be deposited on the inner frame 13 side, it is not necessary to rotate the game board 80 while supporting it. Thereby, the work load is reduced.

  By inserting the game board 80 into the insertion part 290, the projection 431 of the game board 80 and the receiving part 275 of the resin base 70 are caught, and the game board 80 is prevented from falling off from the insertion part 290. For this reason, for example, even if the hand is released from the game board 80 during the above-described rotation operation, the inconvenience of re-installation of the game board 80 is less likely to occur. Thereby, it can contribute to the simplification of work.

  In addition, by suppressing the detachment of the game board 80 from the insertion portion 290, it is possible to suppress variations in the mounting track of the game board 80. Thereby, when rotating the game board 80, it can suppress suitably that the game board 80 interferes with another structure.

  At the time of mounting the game board 80, the game board 80 is inserted into the insertion portion 290, so that the game board 80 is shifted to the blocking state. Therefore, a separate operation for shifting to the blocking state is not required. Therefore, complication of the game board mounting work by adopting the drop-off prevention structure can be avoided.

  The protrusion 431 and the receiving portion 275 are disposed on the front side of the game board 80. Thereby, it is easy to visually confirm whether or not the game board 80 has been switched off. In particular, by forming the protrusions 431 integrally with the second rail cover 400, that is, by collecting a configuration that needs to ensure strength, the expansion of the occupied area on the front side of the game board 80 is suppressed. In this case, there is a concern that the visibility may be lowered due to the standing portion 420 of the second rail cover 400, but in the present embodiment, the second rail cover 400 is made transparent so that the protrusion is projected through the standing portion 420. 431 is visible. Thereby, while suppressing the expansion of an occupation area, the fall of visibility of the processus | protrusion 431 etc. resulting from it is suppressed.

  When the game board 80 can be rotated, for example, a shaft pin that rotatably supports the game board 80 can be provided on the resin base 70. However, when the configuration having the shaft pin is employed, it is necessary to secure a work space for inserting the game board 80 through the shaft pin. Specifically, the work space needs to be secured at least on the extension of the central axis of the shaft pin. For example, it is possible to avoid the overlap between the resin base and the work space by arranging the shaft pin offset to the front or rear of the resin base, but the shaft pin is arranged offset in this way. This is not preferable because it may be a factor that makes it difficult to reduce the thickness of the pachinko machine 10. In this regard, if the game board 80 can be rotated by the protrusion 431 and the receiving portion 275, the above-described disadvantages can be avoided and the thinning of the pachinko machine 10 can be promoted.

  By configuring the game board 80 to be detachable from the resin base 70 as described above, it is possible to contribute to, for example, facilitation of maintenance work and replacement of the game board 80 (model change, etc.). However, it is assumed that the following inconvenience is likely to occur when the game board 80 is detachable. That is, there is a possibility that the game board 80 will be bumped when the game board 80 is transported, or that the game board 80 may interfere with the front door 14 or the inner frame 13 when the game board 80 is attached or detached.

  Parts that affect the movement of the game ball, such as the nail 87 and the guide rail 100, are arranged on the front surface of the game board 80. When these parts are subject to the above-described interference and deformation occurs, the game This is not preferable because the movement of the sphere can be unexpected. In particular, since the guide rail 100 surrounds various components disposed in the game area PE such as the nail 87, it is assumed that the guide rail 100 is likely to be subject to interference as compared with the nail 87 and the like. In addition, the guide rail 100 has a function of guiding the game ball launched from the game ball launching mechanism 110 to the game area PE. If deformation or the like occurs due to the interference, there is a concern that the guidance function is lowered. . According to the present embodiment, by covering the guide rail 100 with the rail covers 350 and 400, it is possible to protect the guide rail 100 and suppress the occurrence of the inconvenience.

  The second rail cover 400 covers the guide rail 100 from the outside of the game area PE and from the front side of the game board 80. Thereby, the protection function of the guide rail 100 is improved.

  In particular, in the configuration in which the game board 80 is inserted into the insertion portion 290 from between the front door 14 and the inner frame 13 (resin base 70) as described above, the front door 14 is located on the front side of the game board 80. It is assumed that the front door 14 and the guide rail 100 are likely to interfere with each other. Therefore, by covering the guide rail 100 from the front door 14 side with the second rail cover 400, interference between the guide rail 100 and the front door 14 can be suitably suppressed.

  When the game board 80 is inserted into the insertion portion 290, it is assumed that the possibility that the portion on the insertion destination side of the guide rail 100 interferes is more likely to interfere than other portions. In this regard, according to the present embodiment, the second rail cover 400 covers the portion of the guide rail 100 that is the front side of the game board 80 in the insertion direction, so that the protection function can be suitably exhibited. it can.

  In addition, the game ball launched from the game ball launching mechanism 110 reaches the game area PE via the portion of the guide rail 100 covered by the second rail cover 400. That is, by covering the portion of the guide rail 100 that constitutes the guide passage 103 with the second rail cover 400, it is possible to secure the guide function of the game ball.

  In the present embodiment, in particular, the front portion of the guide rail 100, the second rail cover 400, and the game board 80 is formed by forming a constriction in the base portion 410 of the second rail cover 400 and the rising portion 420 having the curved portion 421. Are preferably coexisting with each other. That is, the second rail cover 400 is arranged while suppressing the compression of the game area PE partitioned by the guide rail 100. That is, by enjoying the protective function of the second rail cover 400 and suppressing the expansion of the occupied area of the second rail cover 400, a practically preferable configuration is realized.

  In particular, in the region between the guide rail 100 (specifically, the outer rail 102) and the portion protruding from the insertion portion 290 and the end of the game board 80, the second rail cover 400 is allowed to be installed. Is narrower. In this regard, by forming the curved portion 421 that is curved along the outer rail 102 in the standing portion 420, while suppressing the expansion of the occupied region, the strength of the standing portion 420 (specifically, resistance to external force applied from the outside of the game region PE) ).

  Further, the curved portion 421 of the standing portion 420 is formed with a facing portion 450, and the facing portion 450 is connected to the upper standing portion 422 and the lower standing portion 423, thereby further increasing the bending portion 421. Strength improvement can be expected. In particular, the facing portion 450 is formed such that the first facing portion 451 and the second facing portions 452 and 453 are stepped in the front-rear direction. Thereby, further strength improvement is possible.

  The gap between the upper standing part 422 and the lower standing part 423 is widened as the distance from the top part 102a of the outer rail 102 increases, and an inner base part 411 is formed so as to fill the gap. Yes. That is, the inner base portion 411 and the outer base portion 412 are formed on both the upper and lower sides across the curved portion 421. By adopting a configuration having these inner and outer base portions 411 and 412, deformation of the bending portion 421 can be suitably suppressed.

  By providing the projection 431 on the second rail cover 400 that requires strength in this way, the installation area on the front side of the game board 80 can be reduced compared to the case where a configuration corresponding to the projection 431 is separately provided. It is possible.

  Some types of gaming machines that cover the inner frame with the front door frame employ a configuration that takes into account the positional relationship between the inner frame and the front door frame. In such a configuration, although the positional relationship between the resin base of the inner frame and the front door frame can be suitably maintained, the game board provided separately from the resin base and the glass provided on the front door frame It is assumed that it is difficult to suitably maintain the positional relationship with the panel. That is, it is assumed that it is difficult to suppress changes and variations in the relative positions (front and rear positions) of the game board and the glass panel.

  In a configuration in which a game area is provided between the game board and the glass panel and the game ball flows down the game area, the change in the relative position of the game board and the glass panel described above affects the behavior of the game ball in the game area. Can be a factor that affects In a gaming machine having a game board, the advantage and disadvantage are determined by the behavior of the game ball in the game area, so the change in the relative position between the game board and the glass panel as described above is not preferable.

  In this regard, in the present embodiment, the occurrence of the above inconvenience is preferable by adopting a configuration in which the extended portion 39 of the front door 14 is inserted between the second rail cover 400 and the outer rail 102 of the game board 80. The behavior of the game ball flowing down the game area PE can be made favorable.

  In particular, in the present embodiment, by adopting a configuration in which the game board 80 can be attached to and detached from the resin base 70, it contributes to facilitating maintenance work and promoting model change. However, by making the gaming board 80 detachable as described above, it is assumed that the above effect can be expected, but the position variation of the gaming board 80 with respect to the resin base 70 is likely to occur. For this reason, even if the positional relationship between the front door 14 and the resin base 70 can be suitably maintained, the position variation between the game board 80 and the resin base 70 described above is different between the game board 80 and the glass panel 32. It is assumed that this affects the positional relationship. In this regard, by providing the extended portion 39 of the front door 14 and the second rail cover 400 of the game board 80, the above inconvenience is suppressed, maintenance work is facilitated, and the positional relationship between the game board and the panel member is maintained. It is possible to achieve both.

  The extension portion 39 of the front door 14 is interposed between the guide passage 103 and the facing portion 450, and the rear plate surface of the extension portion 39 and the rear plate surface of the glass panel 32 are flush with each other. By doing so, it is possible to contribute to stabilization of the behavior of the game ball passing through the guide passage 103.

  For example, the guide passage 103 may be configured to be covered from the front by the glass panel 32 and the facing portion 450 of the second rail cover 400, but the glass panel 32 is provided on the front door 14 side and the facing portion. Since 450 is provided on the game board 80 side, it is assumed that a gap or a step is likely to occur between the glass panel 32 and the facing portion 450. For this reason, the behavior of the game ball guided by the guide passage 130 is disturbed when passing through these gaps, steps, etc., and it may be difficult to guide the game ball stably. In this regard, as described above, if the guide passage 103 is covered with the extending portion 39 and the glass panel 32 provided so as to be flush with each other, such a disadvantage is eliminated and a practically preferable configuration is realized. it can.

  Further, in the game board 80, the facing portion 450 is disposed at a position near the rotation base end portion of the front door 14 and the extension portion 39 is disposed at the rotation base end portion of the front door 14. The moving direction of the extension 39 when the extension 39 is inserted can be made substantially parallel to the front surface of the game board 80. Therefore, for example, the gap between the facing portion 450 and the extending portion 39 can be reduced, or the hanging allowance (that is, the overlapping allowance in the front-rear direction) between the facing portion 450 and the extending portion 39 can be increased. The function of regulating the spread of the gap can be further improved.

  The front door 14 is supported by support brackets 71 and 72 disposed near the upper and lower ends of the front door 14. Therefore, it is assumed that the gap between the front door 14 and the inner frame 13 is likely to expand at an intermediate portion between the support brackets 71 and 72. Is done. Therefore, by arranging the extending portion 39 and the like on the rotation base end side of the front door 14, it is possible to suitably suppress the occurrence of such inconvenience.

  Further, the front door 14 is preferably prevented from being lifted by the locking device 75 on the rotating front end side of the front door 14, and is easily lifted at the intermediate position between the support fittings 71 and 72 on the rotating base end side. Can be. If a fraudulent tool such as a bar is inserted from the boundary portion with the inner frame 13 on the rotation base end side of the front door 14 and the boundary portion is forcibly expanded, the ball is intentionally blocked in the game area PE. Can be generated. If such a ball clogging occurs near the entrance such as the operation port 83, the following game balls are guided to the operation port 83 by the group of game balls clogged with the balls, to the operation port 83, etc. It is assumed that the winning probability of will change. That is, there is a concern that an attempt to illegally enjoy a privilege by intentionally causing a clogged ball will be made. In this regard, in the present embodiment, the extending portion 39 and the facing portion 450 (specifically, the second facing portion 453) are disposed between the operation port 83 and the boundary portion on the rotating proximal end side. It is possible to suitably suppress the above-described fraud.

  When the extending portion 39 and the facing portion 450 are in contact with each other, stress that lifts from the game board 80 is applied to the second rail cover 400. The second rail cover 400 has an upright portion 420, and the strength against deformation in the front-rear direction is increased. Thereby, even if it is pulled forward by the extension part 39, the deformation of the second rail cover 400 can be suppressed. Therefore, the expansion of the gap can be suitably suppressed.

  As described in detail above, in the configuration in which the positional relationship between the game board 80 (specifically, the front surface thereof) and the glass unit 30 (specifically, the glass panel 32) can be maintained, for example, the extension portion 39 and the opposing portion 450 By increasing the strength, it is possible to improve the function of restricting the spread of the gap. However, it is assumed that it is difficult to improve the strength in such a limited area inside the pachinko machine 10. In particular, the game area PE is formed on the front side of the game board 80, and it is not preferable that the game area PE is pressed due to the strength improvement. Furthermore, the stress generated when the frame body 20 and the like are lifted concentrates on the extending portion 39 and the like, so that the extending portion 39 and the like are easily deformed. Therefore, it can be difficult to ensure the regulatory function. For these reasons, it is assumed that it is difficult to improve the regulation function by relying on strength improvement. In this respect, in the present embodiment, the regulation function is preferably improved by making the glass unit 30 slidable instead of improving the strength. Specifically, the glass unit 30 is attached to the frame body 20 of the front door 14 in a state where sliding movement in the front-rear direction is permitted. For this reason, while the extension part 39 and the opposing part 450 contact | abut, while suppressing the change of the relative position of the game board 80 and the glass unit 30, the load which arises in the extension part 39, the opposing part 450, etc. in connection with it is accompanied. Can be small. Thereby, generation | occurrence | production of the said inconvenience can be suppressed and the positional relationship of the game board 80 and the glass unit 30 can be maintained suitably.

  By making the glass unit 30 movable and holding the glass unit 30 at a specific position by the urging force of the coil spring 46, it is possible to suppress an excessively large stress from being applied to the glass unit 30 or the game board 80. Can do. For example, even if a fraudulent act such as inserting a fraudulent tool such as a bar from the boundary between the inner frame 13 and the front door 14 and forcibly lifting the front door 14 is caused by such an act It is possible to suppress the stress to be concentrated on the glass unit 30 or the game board 80. Thereby, it can contribute to the security | security of the function which controls the expansion of a clearance gap.

  Moreover, the following effects can be expected by making the glass unit 30 movable and the game board 80 fixed. That is, the inner frame 13 is provided with not only the game board 80 but also the game ball launching mechanism 110. By sliding the glass unit 30 as described above, the positions of the game board 80 and the game ball launching mechanism 110 are changed. It is possible to maintain the positional relationship between the glass unit 30 and the game board 80 while suitably maintaining the relationship. That is, compared with the case where the glass unit 30 is fixed and the game board 80 is movable, the above-described crime prevention effect and the like can be exhibited while suppressing the complication of the configuration.

  By making the glass unit 30 movable, it is not preferable that the unauthorized tool can be easily inserted through the window portion 21 of the frame 20. In this respect, in the present embodiment, the movement of the glass unit 30 toward the game board 80 is regulated by the contact portion 282 provided on the plate member 281 of the inner frame 13. Thereby, even if it is a case where the glass unit 30 is pushed, for example, it can suppress that the said clearance gap expands and it can suppress the fall of crime prevention.

  Furthermore, in the movable range of the glass unit 30, it is avoided that the glass unit 30 is detached from the glass unit installation portion 22, and the boundary portion between the glass unit 30 and the frame body 20 is prevented from spreading. Thereby, it is possible to make it difficult to insert an unauthorized tool through the window portion 21 → the boundary portion.

  In the present embodiment, the glass unit 30 is made movable, the glass unit 30 is urged forward by the coil spring 46, and the front limit position is defined by the holding portion 57. Thereby, the positional variation of the glass unit 30 at the time of closing the front door 14 can be suppressed, and smooth transition to the restricted state is achieved.

  Further, the glass unit 20 is urged forward, and the extension portion 39 of the glass unit 30 abuts against the facing portion 450 of the game board 80, thereby restricting the forward displacement of the glass unit 30. It was. For this reason, even if the front door 14 is lifted from the inner frame 13 and the glass unit 30 is further pulled forward, the extension portion 39 and the facing portion 450 are not dependent on the biasing force. The forward displacement of the glass unit 30 is regulated by the hooking. Thus, by making it the structure which blocks the movement of the glass unit 30 ahead rather than relying on an urging | biasing force mechanically, the said clearance gap maintenance function can be improved suitably and the further crime prevention improvement can be anticipated.

  In addition, the following effects can be expected as compared with the configuration in which the extending portion 39 faces the facing portion 450 from the front of the pachinko machine 10. That is, in such a configuration, the extension portion 39 and the facing portion 450 are always in contact with each other in a state in which the front door 14 is closed in order to suitably exhibit the gap maintaining function, and further, the glass unit. By urging 30 to the rear, it is necessary to cause strong interference between the extension part 39 and the facing part 450. In this case, in a normal time when the front door 14 is not lifted up, a larger urging force is applied to the extended portion 39 or the like than when lifted up. 450 functional protection can be difficult. In this regard, in the configuration in the above-described embodiment, when the front door 14 is not lifted up, only a small biasing force is applied or a biasing force is applied compared to the case where the front door is lifted up. Absent. Thereby, the said inconvenience can be wiped off suitably and the extension part 39 and the opposing part 450 can be protected. Therefore, it becomes possible to ensure the said gap maintenance function suitably.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (1) In the said embodiment, the displacement of the relative position of the glass unit 30 and the frame 20 of the front door 14 is permitted by making the glass unit 30 movable, and the glass unit 30 (specifically, the glass panel 32 is detailed). ) And the game board 80 (specifically, the front surface thereof). However, the present invention is not limited to this. By making the game board 80 movable, displacement of the relative position between the game board 80 and the resin base 70 of the inner frame 13 is allowed, and the glass unit 30 (specifically, the glass panel 32) and the game board 80 (specifically, its details). It is good also as a structure which maintains the positional relationship with the front surface. The glass unit 30 and the game board 80 may be movable.

  However, when the game board 80 is movable, the game board 80 moves following the glass unit 30 in accordance with the lifting of the front door 14 from the inner frame 13. At this time, it is not preferable that the front and rear positions of the game board 80 and the game ball launching mechanism 110 that supplies game balls to the game board 80 are shifted. Therefore, when changing the game board 80 to be movable, it is preferable to make the following changes. Specifically, the game ball launching mechanism 110 may be mounted in a state in which sliding movement in the front-rear direction is allowed with respect to the resin base 70, and the game ball launching mechanism 110 may be moved together with the game board 80. Thereby, the positional relationship between the game board 80 and the game ball launching mechanism 110 can be suitably maintained, and a practically preferable configuration can be realized.

  (2) In the above embodiment, the function as the “regulating means” is given to the second rail cover 400 that covers the guide rail 100, but the present invention is not limited to this. That is, a configuration corresponding to the facing portion 450 provided on the second rail cover 400 may be separately provided. In addition, although it is possible to provide a structure corresponding to the facing portion 450 not on the game board 80 but on the resin base 70, in this case, the variation in the positional relationship between the game board 80 and the resin base 70 causes the game board 80 and the glass to be glass. There is a possibility that the positional relationship with the unit 30 may be affected, and the function of maintaining the positional relationship between the game board 80 and the glass unit 30 may be deteriorated. Therefore, a configuration corresponding to the facing portion 450 is desirably provided in the game board 80.

  It is also possible to give the regulation function given to the facing portion 450 to the game board 80 itself. For example, a configuration corresponding to the extending portion 39 of the glass unit 30 may be configured to contact the back surface of the game board 80. In other words, the extending portion 39 and the second rail cover 400 constituting the “regulating means” are configured to be hooked in front of the game board 80, but are not limited thereto. It is also possible to be configured to be caught behind the game board 80. For example, as described above, the extended portion 39 may be hooked on the back surface of the game board 80.

  (3) In the above embodiment, the “regulating means” is constituted by the facing portion 450 of the second rail cover 400 provided in the game board 80 and the extending portion 39 of the glass holder 33 provided in the glass unit 30. The “regulating means” is disposed on the rotation base end side of the front door 14, but is not limited thereto. For example, a configuration corresponding to “regulating means” can be arranged on the front end side of the front door 14.

  For example, a lock device is provided that can be switched between a locked state in which the relative movement of the game board 80 and the glass unit 30 is disabled and an unlocked state in which the relative movement of the game board 80 and the glass unit 30 is allowed, The locking device can be configured to switch to the locked state when the front door 14 is open and to switch to the locked state when the front door 14 is closed. In addition, when adopting such a locking device, further improvement in crime prevention can be expected by adopting a configuration in which the locking device is switched from the locked state to the unlocked state in conjunction with the locking device.

  (4) In the above embodiment, the glass unit 30 as the “panel unit” has a plurality of glass panels 31 and 32, but the number of glass panels is arbitrary. For example, the glass unit 30 may be composed of one glass panel and a glass holder. However, it is preferable to employ at least two panel members in view of improvement in safety and crime prevention.

  Further, the glass panels 31 and 32 constituting the “panel part” are attached to the frame body 20 as the “door frame” via the glass holder 33 also constituting the “panel part”. The glass holder 33 may be omitted, and the glass panels 31 and 32 may be directly attached to the frame body 20. For example, when the “panel part” is composed of a single glass panel, the glass panel can be attached in a slidable state with respect to the frame.

  (5) In the above embodiment, the front door 14 as the “door” is rotatable with respect to the inner frame 13 as the “game machine main body”, but the present invention is not limited to this. . The front door 14 only needs to cover the inner frame 13 from the front of the pachinko machine 10, and the opening and closing method is arbitrary. For example, the front door 14 may be configured to be slidable between a closed position and an open position.

  (6) In the above embodiment, the coil spring 46 as the “biasing means” is attached to the front door 14. However, the attachment target of the coil spring 46 is not limited to the front door 14. For example, the glass unit 30 can be urged forward of the pachinko machine 10 by a coil spring 46 attached to the inner frame 13.

  The coil spring 46 is not an indispensable configuration and can be omitted. However, if the coil spring 46 is omitted, the extension 39 is inserted between the front surface of the game board 80 and the facing portion 450 even when the front door 14 is closed while the position of the glass unit 30 varies. It is preferable to provide a guiding portion for guiding the extending portion 39 as described above. For example, when the one of the leading end portion of the facing portion 450 and the leading end portion of the extending portion 39 hits the other as the guiding portion, the extending portion 39 (the glass unit 30) is guided. It is preferable to form a guiding inclined surface.

  (7) In the above embodiment, the glass unit 30 is attached to the frame body 20 with the screw 45. However, if the glass unit 30 is attached so as to be movable in the front-rear direction, the attachment method is arbitrary. It is. For example, the frame 20 is provided with a lock mechanism that can be switched between a lock position that prevents the glass unit 30 from being removed and a lock release position that allows the glass unit 30 to be removed. It is good to prevent the dropout.

  (8) In the said embodiment, although the glass unit installation part 22 was made into concave shape and it was set as the structure which accommodates the glass unit 30 in the same glass unit installation part 22, it is not limited to this. It suffices to have a configuration corresponding to at least the holding portion 57 that holds the glass unit 30 so as to be slidable, and the glass unit installation portion 22 may be omitted.

  However, when the glass unit installation part 22 is omitted, the glass unit 30 can be moved, so that intrusion of unauthorized tools and the like through the window part 21 can be facilitated. This is not preferable because it can be a factor of reducing crime prevention. Therefore, desirably, a configuration corresponding to the peripheral wall portion 22 a of the glass unit installation portion 22 is provided, and the peripheral wall portion 22 a and the glass unit 30 are overlapped in a direction orthogonal to the sliding direction of the glass unit 30.

  (9) In the above embodiment, the inner frame 13 is provided with the contact portion 282 as a “stopper”, and the contact portion 282 prevents the movement of the glass unit 30 to the game board 80 side. These abutting portions 282 are not essential components and can be omitted. However, when the contact portion 282 and the like are omitted, the gap between the glass unit 30 and the game board 80 can be reduced by pressing the glass unit 30 while the front door 14 is closed. This is not preferable because it may go against the idea of maintaining the gap in the present embodiment. Therefore, the omission of the configuration corresponding to the contact portion 282 is desirably avoided.

  (10) In the above embodiment, the attachment portion 35 and the coil spring 46 of the glass unit 30 are arranged at the same position, but the arrangement of the attachment portion 35 and the coil spring 46 may be arbitrarily changed. However, it is desirable to arrange the coil spring 46 at a position closer to the attachment portion 35 in view of the point that the attachment portion 35 has a function of allowing the glass unit 30 to slide. Instead of the coil spring 46, another spring such as a leaf spring can be employed, and further, another urging member such as rubber can be employed.

  (11) In the above embodiment, the extension unit 39 of the glass unit 30 abuts against the opposing part 450 of the game board 80 from the rear, so that the glass unit 30 cannot be moved forward. . The configuration that disables the forward movement of the glass unit 30 is not limited thereto. For example, if the structure in which the extending part 39 abuts against the facing part 450 from the front is adopted and the glass unit 30 is urged toward the game board 80 by using an urging means such as a coil spring, the glass It becomes possible to suppress the forward movement of the unit 30.

  However, when such a change is made, the initial value of the urging force is set high so that the restriction function does not stop when the relative position shift between the glass unit 30 and the frame 20 becomes large. Need arises. For this reason, it is assumed that the urging force is maximized in a state where the deviation of the relative position is the smallest, and the load generated in the extending portion 39 and the facing portion 450 is increased. This is considered undesirable from the viewpoint of ensuring regulatory functions. On the other hand, in the above-described embodiment, when the relative position shift amount is minimum, the biasing force of the coil spring 46 is also minimum, and it is preferable to avoid an increase in the load generated in the extension portion 39 and the facing portion 450. Can do. Further, when the change in the gap between the glass unit 30 and the game board 80 is very small, it is possible to avoid the contact between the extended portion 39 and the opposing bump 450, and the extended portion 39 and the like are preferably used. It becomes possible to protect. Therefore, desirably, as shown in the above-described embodiment, the extending portion 39 as the “restricting portion” on the glass unit 30 side contacts the opposing portion 450 as the “restricting portion” on the game board side from the rear. A (facing) configuration may be employed.

  (12) In the above embodiment, the insertion portion 290 is arranged on the same side as the side on which the front door 14 is pivotally supported in the inner frame 13 (specifically, the resin base 70). It is also possible to arrange the insertion part 290 on the side opposite to the side on which the front door 14 is pivotally supported. However, when such a change is made, it is assumed that the front door 14 tends to obstruct the work when the game board 80 is attached and detached. Certainly, it is possible to suppress a decrease in workability by increasing the opening amount of the front door 14, but such a response is not preferable because the work space can be unnecessarily widened. In particular, it is not preferable that the front door 14 needs to be largely opened in a state where it is installed in an island facility such as a game hall, because it may be a factor that hinders games in adjacent game machines. In this regard, as shown in the above-described embodiment, if the insertion portion 290 is arranged on the same side as the side on which the front door 14 is pivotally supported, the above disadvantages can be eliminated and a practically preferable configuration can be realized.

  (13) In the above embodiment, the game board 80 is configured to be placed at the mounting completion position by rotating, but the present invention is not limited to this. For example, it is possible to adopt a configuration in which the game board 80 can be disposed at the mounting completion position by sliding the game board 80 in a predetermined direction.

  (14) In the above embodiment, the game board 80 is detachable from the front of the resin base 70 with respect to the resin base 70. However, the game board 80 is changed from the rear of the resin base 70 by changing this. A detachable configuration is also possible.

  (15) In the above embodiment, the “panel member” is made of glass, but may be made of synthetic resin. Thus, when making a panel member into a product made from a synthetic resin, it is also possible to perform the following changes collectively. That is, a configuration corresponding to the extending portion 39 can be provided in the panel member.

  (16) Other types of pachinko machines different from the above embodiment, for example, a pachinko machine in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or a game ball in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a right if a player enters, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and other gaming machines.

<Invention Group Extracted from the Embodiments>
Hereinafter, the features of the invention group extracted from the above-described embodiment will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in the above embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Features 1. A gaming machine body (inner frame 13) in which a game board (game board 80) in which a game area (game area PE) in which a game ball flows down is formed on the front side is mounted on a body frame (resin base 70);
A panel portion (glass unit 30) formed so as to cover the gaming board from the front of the gaming machine and be visible to the gaming area is disposed in front of the gaming machine main body and is connected to the gaming machine main body. A door body (front door 14) mounted on a door frame (frame body 20) provided to be openable and closable,
When the door is closed with respect to the gaming machine main body and provided on the gaming board and the panel unit, a regulating means for regulating a change in a gap between the gaming board and the panel unit (of the glass unit 30). Extending portion 39, and facing portion 450) of game board 80,
At least one of the game board and the panel portion is disposed so that relative displacement in the front-rear direction with respect to its own mounting target is allowed at least in a state where the change in the gap is restricted by the restriction means. A gaming machine characterized by being made.

  Some types of gaming machines in which the gaming machine main body is covered with a door body adopt a configuration that takes into account the positional relationship between the main body frame and the door frame. In such a configuration, although the positional relationship between the main body frame and the door frame can be suitably maintained, the game board provided separately from the main body frame and provided separately from the door frame. It is assumed that it is difficult to suitably maintain the positional relationship with the panel portion. That is, it is assumed that it is difficult to suppress changes and variations in the relative positions (front and rear positions) of the game board and the panel unit.

  In a configuration in which a game area is provided between the game board and the panel portion, and the game ball flows down through the game area, the change in the relative position of the game board and the panel portion described above affects the behavior of the game ball in the game area. Can do. In a gaming machine having a game board, the advantage and disadvantage are determined by the behavior of the game ball in the game area, so it is not preferable that the relative position between the game board and the panel member changes.

  In this regard, according to this feature, the restriction means provided in the panel portion and the game board restricts the change in the gap between the game board and the panel portion (for example, the change in the interval between the game board and the panel portion). The occurrence of inconvenience can be suitably suppressed, and the behavior of the game ball flowing down the game area can be made favorable.

  In addition, even when the positional relationship between the main body frame and the door frame changes due to, for example, the door frame floating from the main body frame, the front-rear direction of at least one of the game board and the panel unit and the mounting target is accordingly changed. The above gap is maintained by changing the relative position to. As a result, while suppressing variations in the position and gap of the game board and the panel part due to the change in the positional relationship between the main body frame and the door frame, the load generated in the regulating means can be reduced, and the game board and panel part Deformation can be suppressed. Therefore, it is possible to suitably maintain the positional relationship between the game board and the panel unit.

  Note that the game board and the panel portion shown in this feature are not necessarily parallel. That is, it is not limited to the configuration in which the gap is constant at all locations. For example, when the front surface of the game board is a flat surface, the rear surface of the panel portion can be a curved surface. Furthermore, the “change in the gap” in this feature is not necessarily limited to the change in the shortest distance between the game board and the panel part, but includes the change in the distance between arbitrary places in both the game board and the panel part. Yes.

Feature 2. The regulating means regulates a change in the gap from a regulation release state in which the change in the gap between the game board and the panel unit is not regulated based on the movement of the door body to the closed position with respect to the gaming machine main body. It is provided so that it can be switched to a regulated state.
An abutting portion (holding portion) that determines a limit position of the relative displacement on the abutting side by abutting from the front or the rear against one of the game board and the panel portion where the relative displacement is allowed. 57 tip)
2. The gaming machine according to claim 1, further comprising urging means (coil spring 46) for urging the displaceable one toward the contact portion.

  As shown in the feature 1, in the configuration in which the game board and the panel unit are provided with the restricting means and at least one of the game board and the panel unit is mounted so as to be displaceable, a configuration that allows relative displacement is adopted. Since it becomes difficult to determine the position of these displaceable components when closing the door body, it may be difficult to switch the restricting means to the restricted state.

  In this regard, as shown in this feature, by using the contact portion and the urging means in combination, it is possible to suppress the above-described position variation when closing the door body. Thereby, the smooth transition to the said restriction | limiting state is realizable, employ | adopting the structure which can displace a panel part and a game board.

Feature 3. The abutting portion defines the limit position by abutting from the opposite side to the other of the game board and the panel portion where the relative displacement is allowed,
The restricting means includes a panel portion side restricting portion provided on the panel portion and a game board side restricting portion provided on the game board and facing the panel portion side restricting portion from the rear side, and the game board 3. The gaming machine according to claim 2, wherein an expansion of a gap between the game board and the panel unit is regulated by a side regulating unit and the panel unit side regulating unit coming into contact with each other in the front-rear direction.

  According to the feature 3, in the state where the restricting means is switched to the restricting state, when the door body is lifted, the gap between the game board and the panel portion can be mechanically stopped. For example, when the game board side regulation part and the panel part side regulation part are in contact with each other (regulation state), one of the game board and the panel part is pulled to the side where the gap between both is widened. However, it does not resist such acts depending on the urging force, but it can resist the acts by being caught between the regulating parts. Thereby, the said clearance gap maintenance function can be improved suitably compared with the structure which suppresses the expansion of a clearance gap depending on the biasing force of a biasing means, for example.

Feature 4. A gaming machine body (inner frame 13) in which a game board (game board 80) in which a game area (game area PE) in which a game ball flows down is formed on the front side is mounted on a body frame (resin base 70);
A panel portion (glass unit 30) formed so as to cover the gaming board from the front of the gaming machine and be visible to the gaming area is disposed in front of the gaming machine main body and is connected to the gaming machine main body. A door body (front door 14) mounted on a door frame (frame body 20) provided to be openable and closable,
When the door is closed with respect to the gaming machine main body and provided on the gaming board and the panel unit, a regulating means for regulating a change in a gap between the gaming board and the panel unit (of the glass unit 30). Extending portion 39 and facing portion 450) of game board 80,
The panel portion is mounted on the door frame such that relative displacement in the front-rear direction with respect to the door frame is allowed at least in a state in which a change in the gap is restricted by the restriction means. A gaming machine.

  Some types of gaming machines in which the gaming machine main body is covered with a door body adopt a configuration that takes into account the positional relationship between the main body frame and the door frame. In such a configuration, although the positional relationship between the main body frame and the door frame can be suitably maintained, the game board provided separately from the main body frame and the door frame are provided separately. It is assumed that it is difficult to favorably maintain the positional relationship with the panel unit. That is, it is assumed that it is difficult to suppress changes and variations in the relative positions (front and rear positions) of the game board and the panel unit.

  In a configuration in which a game area is provided between the game board and the panel portion, and the game ball flows down through the game area, the change in the relative position of the game board and the panel portion described above affects the behavior of the game ball in the game area. Can do. In a gaming machine having a game board, the advantage and disadvantage are determined by the behavior of the game ball in the game area, so it is not preferable that the relative position between the game board and the panel member changes.

  In this regard, according to this feature, the restriction means provided in the panel portion and the game board restricts the change in the gap between the game board and the panel portion (for example, the change in the interval between the game board and the panel portion). The occurrence of inconvenience can be suitably suppressed, and the behavior of the game ball flowing down the game area can be made favorable.

  Even when the front and rear positions of the main body frame and the door frame vary, the gap is maintained by changing the relative position of the panel portion and the door frame accordingly. As a result, it is possible to suppress variations in the position of the game board and the panel due to variations in the positions of the main body frame and the door frame (ie, changes in the gap between the game board and the panel), and the positions of the game board and the panel. The relationship can be suitably maintained.

  In addition, the game board has a flow-down area where game balls flow down. For this reason, it is assumed that the influence on the flow-down mode of the game ball is increased when the game board is movable as compared with the case where the panel portion is movable (configuration allowing displacement). Therefore, as shown in this feature, if the panel part is movable, and the configuration is such that the positional variation between the door frame and the main body frame is absorbed by the displacement of the relative position between the panel part and the door frame, the game board is not necessarily displaced. By doing so, it is not necessary to absorb the variation in position, and the above inconvenience can be suitably eliminated.

  Note that the game board and the panel portion shown in this feature are not necessarily parallel. That is, it is not limited to the configuration in which the gap is constant at all locations. For example, when the front surface of the game board is a flat surface, the rear surface of the panel portion can be a curved surface. Furthermore, the “change in the gap” in this feature is not necessarily limited to the change in the shortest distance between the game board and the panel part, but includes the change in the distance between arbitrary places in both the game board and the panel part. Yes.

  Feature 5. The gaming machine according to claim 4, further comprising an attachment portion (attachment portion 35, screw 45, and holding portion 57) for attaching the panel portion in a state in which the panel portion can be displaced in the front-rear direction with respect to the door frame.

  In order to realize the configuration shown in the feature 4, it is preferable to devise the attachment of the panel portion as shown in the feature.

  For example, when adopting a configuration in which the panel portion includes a transparent panel having transparency and a panel holder for holding the transparent panel, it is desirable to attach the panel holder to the door frame by the mounting portion. Specifically, when a configuration is adopted in which the panel holder is omitted and the transparent panel is directly attached to the door frame, it is necessary to provide stoppers on both the front and rear sides of the transparent panel. It is assumed that it protrudes to the game board side. Such an overhang is not preferable because it may cause a pressure on the game area. In this regard, if the above displacement is allowed by attaching a panel holder, it is possible to easily avoid the configuration allowing the displacement of the panel portion from projecting to the rear side of the transparent panel. The permissible configuration can be suitably coexisted with a game board (specifically, a game area) in a limited space.

Feature 6 The game board has a partition portion (guide rail 100) that stands up from the front of the game board and forms a guide portion (guide passage 103) for guiding the game ball to the game region and the game region. And
The mounting portion and the restricting means are disposed along the partition portion,
6. The gaming machine according to claim 5, wherein the attachment portions are arranged on both sides of the restricting means.

  In the configuration in which the positional relationship between the panel portion and the game board is maintained by the regulating means as shown in the feature 4 etc., it is particularly important to maintain the positional relationship between the portion where the game area or the guide portion is provided and the panel portion. It becomes. Therefore, as shown in this feature, a practically preferable configuration can be realized by disposing the attachment portion and the regulating means along the partition portion. Moreover, by arranging the attachment portions on both sides of the restricting means, it is possible to contribute to stabilization of the maintenance function.

Feature 7. The regulating means regulates a change in the gap from a regulation release state in which the change in the gap between the game board and the panel unit is not regulated based on the movement of the door body to the closed position with respect to the gaming machine main body. It is provided so that it can be switched to a regulated state.
A panel portion contact portion (the front end portion of the holding portion 57) that defines a limit position on the front side of the panel portion by contacting the panel portion from the front;
The panel part urging means (coil spring 46) for urging the panel part toward the panel part abutting part is provided. Gaming machine.

  As shown in feature 4 and the like, in the configuration in which the game board and the panel portion are provided with the restricting means and the relative displacement between the panel portion and the door frame is allowed, the positional relationship between the game board and the panel portion is preferably maintained. On the other hand, since the position of the panel portion becomes difficult to be determined, the transition of the restricted state can be difficult.

  In this regard, as shown in this feature, the panel portion is closed when the door body is closed by biasing the panel portion toward the panel contact portion (limit position) by the panel portion biasing means. The variation in the position of can be suppressed. Thereby, smooth transition to a regulation state is realizable, adopting composition which permits relative displacement with a panel part and a door frame.

Feature 8 The door frame has a panel installation part (glass unit installation part 22) in which the panel part is installed from the game board side,
The gaming machine according to claim 7, wherein the panel contact portion (the front end portion of the holding portion 57) is formed on the same side of the door frame as the panel installation portion.

  In the configuration that maintains the positional relationship between the panel unit and the game board by making the panel unit movable as shown in the feature 4 and the like, it may be necessary to secure a displacement region that allows relative displacement between the two. . For example, when it is set as the structure which installs a panel part from the front with respect to a door frame, it will be necessary to form the door frame (panel installation part) in anticipation of the said displacement area | region beforehand, and the thickness of a door body will increase. is assumed. In this regard, as shown in this feature, if the panel portion can be installed from the back side of the door frame, the door frame is lifted from the main body frame, and the door frame is moved away from the panel portion. Therefore, the prospect of the displacement region becomes unnecessary, and the increase in the thickness of the door body can be suppressed. That is, while maintaining the positional relationship between the panel unit and the game board suitably, an increase in the thickness of the door body associated therewith can be suppressed.

Feature 9 A game board installation part (game board accommodating part 73) provided on the main body frame, in which the game board is installed from the front of the game machine;
A game board contact portion (resin base) which is provided on the main body frame and determines a limit position on the front side of the game board by contacting the game board installed in the game board installation section from the front of the game machine. 70 stopper portions 271 and the like)
An urging means for the game board for urging the game board toward the contact part for the game board;
Panel portion biasing means (coil spring 46) for biasing the panel portion to the opposite side of the game board side;
The regulating means is
A game board side regulating portion (opposing portion 450) provided in the game board;
A panel side regulating portion (extension) provided on the panel portion and facing from the near side in the urging direction by the panel portion urging means to the game board side regulating portion with the door closed. A gaming machine according to any one of features 4 to 6, characterized in that the gaming machine has a portion 39).

  According to the feature 8, in the configuration in which the game board is installed from the front with respect to the main body frame by pressing the game board installed in the game board installation unit against the game board contact portion by the game board urging means. The game board can be positioned with reference to the front surface of the game board. For example, even if the thickness of the game board varies due to a manufacturing error or the like, the variation can be allowed while ensuring the positional accuracy. If attention is paid to the fact that a game area is formed on the front surface of the game board, a practically preferable configuration can be realized by improving the positional accuracy of the front surface of the game board as described above.

  In this way, when the game board is positioned with respect to the front surface by the game board contact portion and the game board urging means, it is not preferable that a force acts to push the game board backward. In this regard, in this feature, such inconvenience can be suitably suppressed. Specifically, when the door frame floats forward with respect to the main body frame, the panel side restriction portion comes into contact with the game board side restriction portion from the front side in the urging direction by the panel portion urging means. As a result, the spread of the gap between the game board and the panel portion is suppressed. At this time, the gaming board side regulating portion is pushed forward of the gaming machine by the panel side regulating portion. For this reason, it is possible to prevent the game board from being displaced backward (that is, away from the game board contact portion) against the biasing force of the game board biasing means. On the other hand, when the door frame sinks to the main body frame side, the panel side regulating portion is displaced to the side away from the game board side regulating portion. Therefore, it can avoid that the game board side control part is pushed back, and can eliminate the said inconvenience.

  Further, by urging the game board and the panel unit by each urging means, it is possible to suppress variations in the mounting positions of the game board and the panel unit. Thereby, interference of both the control parts at the time of closing a door body can be suppressed. In particular, by aligning the urging directions of the panel unit and the game board, even if the mounting position of the panel unit and the game board is shifted so as to resist the urging force, the variation in the mounting position of both of them Accumulation can be reduced, and it is possible to prevent the transition to the restricted state from becoming difficult.

  Feature 10 The gaming machine according to any one of features 7 to 9, wherein the panel unit urging means is disposed on the door frame.

  According to the feature 10, by disposing the panel urging means on the door frame, the occupied area of the panel urging means and the configuration associated therewith can be reduced.

  In addition, the following effects can be expected as compared with the case where the panel urging means is disposed on the gaming machine main body side. That is, it is possible to suppress variation in relative position between the door frame and the panel portion when the door body is open, and it is preferable to shift to the restricted state when the door body is closed with respect to the gaming machine body. Can be.

Feature 11. The panel portion is disposed at a position covering an opening (window portion 21) formed in a portion of the door frame that is in front of the game board from the game board side,
The door frame is
While extending along the periphery of the panel portion, and surrounding the panel portion (peripheral wall portion 22a),
When the relative displacement amount of the panel portion and the door frame reaches a predetermined amount, a blocking portion (head portion of the screw 45) that prevents the relative displacement of the panel portion and the door frame by abutting against the panel portion. 45a)
The surrounding portion is formed so that the overlap between the panel portion and the surrounding portion is maintained within a range in which relative movement between the door frame and the panel portion is allowed. The gaming machine according to any one of features 4 to 10.

  When the panel part is movable as shown in the feature 4 etc., the relative position between the panel part and the door frame is changed, and the gap between the two is widened. Unauthorized access to the game area can be facilitated through the gap. This is not preferable from the viewpoint of improving crime prevention. Therefore, as shown in this feature, if the overlap between the panel portion and the surrounding portion is maintained within a range in which relative movement between the door frame and the panel portion is allowed, the gap maintaining function can be achieved. Even when the relative position between the panel portion and the door frame is changed, the spread of the gap between the game board and the door frame can be suppressed. Thereby, the fall of crime prevention can be suppressed.

  In particular, in the combination with the feature 9, the “enclosed portion” shown in the feature 9 can be the same as the “panel installation portion” shown in the feature. The “contact portion” shown in this feature can be the same as the “part”.
