Particularly in the present embodiment, the game board 80 is detachably attached to the resin base 70, thereby facilitating maintenance work and the like.

  The game board 80 includes a wooden plywood and a sheet material that covers a front plate surface of the plywood, and the front surface of the game board 80 is exposed to the front side of the resin base 70 through an open portion of the game board housing portion 73. . 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 wooden, 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. By various configurations such as the nail 87 and the windmill, the flow path of the game ball is differentiated and adjusted so that the winning to the above-described general winning opening 81 or the like occurs with an appropriate probability.

  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. A bearing portion 133 is formed on the bearing bracket 132 so as to be separated from each other in the vertical direction, and the back pack unit 15 is rotatably attached to the inner frame 13 by these bearing portions 133. A plurality of fixing levers 134 for fixing the back pack unit 15 to the inner frame 13 are provided on the back surface of the resin base 70.

  A central opening 74 that penetrates in the thickness direction of the resin base 70 and opens to the back side of the resin base 70 is formed in the bottom portion (opposing plate portion 251 described later) of the game board housing portion 73 in the resin base 70. The central opening 74 is covered from the front side of the inner frame 13 by the game board 80 housed in the game board housing part 73. Various components such as a control device are mounted on the back of the game board 80, and these various components are exposed to the back side of the inner frame 13 through the central opening 74. 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 held down, 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. It has a ring shape surrounding it. 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.

  Further, 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 partition 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, specifically the end on the insertion part 290 side of the game board 80 and the guide rail 100 (more specifically, the outer side). 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, is forward from the edge portion. 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)
In the present embodiment, in particular, when the front door 14 is closed, there is provided a regulation mechanism that regulates the expansion of the gap between the game board 80 and the glass unit 30 (specifically, the glass panel 32). One. Hereinafter, first, the configuration relating to the glass unit 30 will be described based on FIG. 3, FIG. 4 and FIG. 16, and then the regulating mechanism will be described in detail. FIG. 16 is a partial cross-sectional view taken along line BB in FIG.

  As already described, the glass unit 30 includes the glass panels 31 and 32 held by the glass holder 33 (specifically, the frame portion 34), and the glass panels 31 and 32 are accommodated in the region surrounded by the frame portion 34. (See FIG. 4).

  As shown in the partial cross-sectional view of FIG. 16, the frame portion 34 is formed with a partition portion 36 that partitions the enclosed region back and forth. The partition portion 36 stands up toward the center side of the frame portion 34 and forms a protrusion that extends in the circumferential direction of the frame portion 34. That is, the accommodating portions 37 and 38 that accommodate the glass panels 31 and 32 are partitioned by the partition portion 36. Thereby, a predetermined gap is secured between the glass panels 31 and 32, and interference between the glass panels 31 and 32 is avoided. In the following description, for convenience, the front glass panel 31 is referred to as “front glass panel 31”, and the rear glass panel 32 is referred to as “rear glass panel 32”.

  The front glass panel 31 and the rear glass panel 32 are arranged in a state of facing each other with the partition portion 36 interposed therebetween. The front glass panel 31 is fixed to the frame portion 34 (specifically, the partition portion 36) using an adhesive, and cannot be moved relative to the glass holder 33. Thus, if attention is paid to the fact that the front glass panel 31 is fixed so as not to move, the front glass panel 31 can also be referred to as a “fixed panel 31”.

  On the other hand, the rear glass panel 32 is held in a state in which sliding movement in the direction in which the inner frame 13 and the front door 14 are juxtaposed (that is, the front-rear direction in the pachinko machine 10) is allowed. That is, the rear glass panel 32 is allowed to move relative to the glass holder 33. The holding structure of the rear glass panel 32 by the glass holder 33 will be described in detail.

  As shown in FIG. 4, the housing portion 38 for the rear glass panel 32 has a substantially annular shape extending along the periphery of the rear glass panel 32. More specifically, as shown in FIG. 16, the accommodating portion 38 is continuous with the partition portion 36 and is opposed to the front plate surface of the rear glass panel 32, and the rear glass panel 32. The rear wall portion 42 that faces the rear plate surface and the side wall portion 43 that connects both the wall portions 41 and 42 and faces the end surface of the rear glass panel 32, the inner side of the frame portion 34 as a whole. It has a groove shape that is open toward Thus, the movement of the rear glass panel 32 in the surface expansion direction is restricted by fitting almost the entire periphery of the rear glass panel 32 in the region surrounded by the walls 41 to 43.

  The gap dimension L1 between the front wall part 41 and the rear wall part 42 is set to be larger than the thickness dimension L2 of the rear glass panel 32, thereby permitting sliding movement of the glass panel 32 in the front-rear direction. Yes. That is, the rear glass panel 32 is allowed to move relative to the glass holder 33 in the front-rear direction. Thus, if attention is paid to the fact that the rear glass panel 32 is movable, the rear glass panel 32 can also be referred to as a “movable panel 32”.

  As shown in FIG. 2, the rear glass panel 32 has an edge on the side of the rotation base end of the front door 14, more specifically, a portion that is arranged side by side with the operation port 83 as a ball entry portion. An extension part 49 extending to the side is formed, and a series of openings 44 are formed in the side wall part 43 and the rear wall part 42 of the accommodating part 38 so as to correspond to the extension part 49. . The opening 44 has a size that allows the extension 49 to pass through, and the extension 49 protrudes toward the rotation base end of the front door 14 through the opening 44.

  As shown in FIG. 4, the glass holder 33 is formed by combining a pair of upper and lower holder structures 33 a and 33 b, and the combination direction of the holder structures 33 a and 33 b is that of the rear glass panel 32 with respect to the glass holder 33. It is the same as the mounting direction (specifically, the direction orthogonal to the sliding direction of the rear glass panel 32). Furthermore, the holder constituting bodies 33 a and 33 b are formed so that the boundary position between them overlaps the opening 44. These are contrivances for avoiding the extended portion 49 and the frame portion 34 from being caught when the rear glass panel 32 is attached to the glass holder 33, and suppressing a decrease in workability.

  Incidentally, when the glass holder 33 is divided as described above, it is difficult to secure the holding strength of the rear glass panel 32 by the glass holder 33. This is not preferable because the above-described rear glass panel 32 and the frame 20 may cause a decrease in the stability of relative movement. In this regard, in the present embodiment, the front glass panel 31 is bonded to the glass holder 33 (specifically, both holder structural bodies 33a and 33b), and the holder structural bodies 33a and 33b are connected by the front glass panel 31. Thus, the glass holder 33 can be reinforced. Thereby, the occurrence of the inconvenience is suppressed.

  As an urging means for urging the rear glass panel 32 toward the front wall 41 side (that is, the side away from the game board 80) on the upper and lower sides across the opening 44 in the rear wall portion 42 of the housing portion 38, A leaf spring 57 is attached. The plate spring 57 is formed by folding a metal plate into a V shape, and the folded portion is arranged so as to face upward, that is, the front side in the mounting direction of the rear glass panel 32 with respect to the glass holder 33. . Thus, when the rear glass panel 32 is mounted on the glass holder 33, the rear glass panel 32 and the plate spring 57 are prevented from being caught.

  The rear glass panel 32 is pressed against the front wall portion 41 of the housing portion 38 by the leaf spring 57. That is, the rear glass panel 32 is in a standby state at a front limit position within a slidable range. In the case of adopting a configuration in which the rear glass panel 32 is movable, when the position of the rear glass panel 32 varies when the front door 14 is closed with respect to the inner frame 13, the rear glass panel 32 is There is a possibility of interference with the game board 80. In view of the fact that the game area PE is formed on the front surface of the game board 80, the occurrence of such interference is not preferable because it can cause the flow path of the game ball in the game area PE to change. In this regard, as described above, if the rear glass panel 32 is made to stand by at a predetermined position by the plate spring 57, the above inconvenience can be preferably avoided. In particular, a practically preferable configuration is realized by waiting the rear glass panel 32 at the front limit position farthest from the game board 80 in the slidable range.

  If it explains supplementarily about attachment of leaf spring 57, leaf spring installation part 45 dented on the opposite side to the rear side glass panel 32 will be formed in the part which counters rear side glass panel 32 in back wall part 42. The leaf spring 57 is fixed to the leaf spring installation portion 45. When the relative position of the rear glass panel 32 and the frame body 20 changes and the leaf spring 57 is compressed, the leaf spring 57 is accommodated in the leaf spring installation portion 45, and the rear surface of the rear glass panel 32. Will come into contact with the rear wall 42. As a result, further relative displacement is prevented. As described above in detail, if attention is paid to the point that the front wall part 41 and the rear wall part 42 prevent relative movement of the frame body 20 and the rear glass panel 32 and the point that the slide limit position is defined. These wall portions 41 and 42 can also be referred to as “limit position defining portions 41 and 42” or “stopper portions 41 and 42”.

  Next, the restriction mechanism will be described with reference to FIGS. 12, 13, 17 and 18. FIG. 17 is a schematic view showing the positional relationship between the second rail cover 400 and the glass unit 30, and FIG. 18 is a partial cross-sectional view taken along the line CC of FIG. In FIG. 17, for convenience, a part of the glass unit 30 is represented using a two-dot chain line and dot hatching.

  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. 17, 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. 18, the first facing portion 451 faces the front end edge of the outer rail 102 with a slight gap, and the second facing portions 452 and 453 face 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, specifically, the extended portion 49 of the rear glass panel 32 is fitted in the gap between the outer rail 102 and the second facing portion 452.

  The extending portion 49 has a flat plate shape extending from the glass unit 30 toward the curved portion 421 of the second rail cover 400, and at least a tip portion thereof fits into a gap between the second facing portion 452 and the outer rail 102. ing. The plate surface of the extending portion 49 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. It is also possible to adopt a configuration in which the extending portion 49 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 part 49 comes into contact with the second facing part 452, and the gap between the rear glass panel 32 and the game board 80 is reduced. Expansion will be regulated.

  As described in detail above, by combining the configuration that restricts the expansion of the gap between the glass unit 30 and the game board 80 and the configuration that allows the relative movement of the frame 20 and the rear glass panel 32 in the front door 14, The positional relationship between the rear glass panel 32 and the game board 80 can be suitably maintained, and further contribute to the improvement of the crime prevention function. Here, the positional relationship between the rear glass panel 32 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 view showing the positional relationship between the game board 80 and the rear glass panel 32.

  In the state where the front door 14 is closed with respect to the inner frame 13 as shown in FIG. 19A, the rear glass panel 32 is opposed to the facing portion 450 of the game board 80 (specifically, the second rail cover 400). The extending part 49 is opposed with a slight gap. In this state, the rear glass panel 32 stands by at a position that is the front limit position (closer to the frame body 20) that is closest to the front in the range that can be slid by the urging force of the leaf spring 57.

  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 portion 49 abuts against the facing portion 450 from the rear side, so that the extension portion 39 following the frame body 20 of the front door 14 is prevented from moving. . Specifically, the relative position between the rear glass panel 32 and the frame body 20 is changed by compressing the leaf spring 57 (see FIG. 18). That is, even if the frame 20 is lifted from the inner frame 13, the rear glass panel 32 remains substantially in the original position. Thereby, the positional relationship between the game board 80 (specifically, the front surface thereof) and the rear glass panel 32 is suitably maintained.

  Even when the frame 20 is lifted from the inner frame 13, at least the front glass panel 31 and the glass holder 33 of the glass unit 30 are displaced following the frame 20. The relative position of the frame 20 with respect to the window portion 21 does not change, and the window portion 21 remains closed by the front glass panel 31. Thereby, even if it is a case where the said floating | lifting generate | occur | produces, it can suppress that insertion of an unauthorized tool etc. through the window part 21 becomes easy.

  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 49 of the rear glass panel 32 is moved to the second rail cover by closing the front door 14 as shown in FIG. 22 (e) → FIG. 22 (f). 400 is inserted between the outer rail 102 and the extended portion 49 facing the second facing portion 452 from the rear. Thereby, the expansion of the gap between the game board 80 and the rear glass panel 32 is restricted.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 23, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 801 provided in the main controller 162 incorporates a main control circuit 802 and a power failure monitoring circuit 803. An MPU 811 is mounted on the main control circuit 802. The MPU 811 includes a ROM 812 that stores various control programs executed by the MPU 811 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 812 is executed. A RAM 813 and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated.

  The RAM 813 is configured such that even after the power of the pachinko machine 10 is shut off, the data storage holding power is supplied from the power / fire control board 821 provided in the power / fire control device 243 to hold the data.

  An input / output port is connected to the MPU 811 via a bus line including an address bus and a data bus. Connected to the input side of the main control circuit 802 are a power failure monitoring circuit 803 provided on the main control board 801, a payout control board 822 provided on the payout control device 242, and other switches not shown. In this case, a power / fire control board 821 is connected to the power failure monitoring circuit 803, and power is supplied to the main control circuit 802 via the power failure monitoring circuit 803.

  On the other hand, a power failure monitoring circuit 803, a payout control board 822 and a relay terminal board 823 are connected to the output side of the main control circuit 802. Various commands such as a prize ball command are output to the payout control board 822. Various commands and the like are output from the main control circuit 802 to the sound lamp control board 824 provided in the sound lamp control device 143 via the relay terminal plate 823.

  The power failure monitoring circuit 803 relays the main control circuit 802 and the power supply / launch control board 821 and monitors the DC stable 24 volt power source that is the maximum power output from the power supply / fire control board 821.

  The payout control board 822 controls payout of prize balls and rental balls by the payout device 224. The MPU 831 that is an arithmetic unit includes a ROM 832 that stores a control program executed by the MPU 831, fixed value data, and the like, and a RAM 833 that is used as a work memory or the like.

  Similar to the RAM 813 of the main control circuit 802, the RAM 833 of the payout control board 822 is configured such that the data storage holding power is supplied from the power supply / launch control board 821 even after the power supply of the pachinko machine 10 is shut off. It has become.

  An input / output port is connected to the MPU 831 of the payout control board 822 via a bus line including an address bus and a data bus. On the input side of the payout control board 822, a main control circuit 802, a power / fire control board 821, and a backpack board 829 are connected. The main control circuit 802 and the back pack substrate 829 are connected to the output side of the payout control substrate 822.

  The power / fire control board 821 includes a power supply unit and a fire control unit. The power supply unit supplies necessary operating power to the main control circuit 802, the payout control board 822, and the like through a path indicated by a double line arrow. The launch control unit is responsible for launch control of the game ball launching mechanism 110 in accordance with the operation of the game ball launch handle 29 by the player, and the game ball launching mechanism 110 is driven when predetermined launch conditions are met. .

  The sound lamp control board 824 controls the various lamp units 23 to 25, the speaker unit 26, and the display control device 825. The MPU 841 that is an arithmetic unit includes a ROM 842 that stores a control program executed by the MPU 841, fixed value data, and the like, and a RAM 843 that is used as a work memory or the like.

  An input / output port is connected to the MPU 841 of the sound lamp control board 824 via a bus line including an address bus and a data bus. The main control circuit 802 is connected to the input side of the sound lamp control board 824 by relaying to the relay terminal plate 823. 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 above-described inconvenience is suitably achieved by adopting a configuration in which the extending portion 49 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 49 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 49 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 49 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 49 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 49 is disposed at the rotation base end portion of the front door 14. The moving direction of the extension 49 when the extension 49 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 49 can be reduced, and the hanging allowance (that is, the overlapping allowance in the front-rear direction) of the facing portion 450 and the extending portion 49 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 extended portion 49 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 49 and the facing portion 450 (specifically, the second facing portion 453) are disposed between the operating port 83 and the boundary portion on the rotation base end side. It is possible to suitably suppress the above-described fraud.

  When the extending portion 49 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 extending portion 49, 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 49 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 or the like is lifted concentrates on the extension portion 49 or the like, so that the extension portion 49 or the like is likely to be 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 allowing the rear glass panel 32 to be slidable, rather than improving the strength. Specifically, the rear glass panel 32 is attached to the glass holder 33 (the frame body 20 of the front door 14) while allowing relative movement in the front-rear direction. For this reason, the extension portion 49 and the facing portion 450 abut against each other, and a change in the relative position between the game board 80 and the rear glass panel 32 is suppressed, and accordingly, the extension portion 49 and the facing portion 450 are generated. The load can be reduced. 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.

  In the configuration in which the frame body 20 of the front door 14 has the window portion 21, there is a concern that the strength of the front door 14 (specifically, the frame body 20) around the window portion 21 is reduced. It is assumed that the relative displacement is likely to be hindered if the glass unit 30 is affected by a door frame distortion or the like due to a decrease in strength. In this respect, in this feature, the glass panels 31 and 32 are not directly fixed to the door frame, but are fixed to the frame body 20 via the glass holder 33 as a target of relative displacement. Thereby, the influence of the distortion or the like is suppressed. In particular, the glass holder 33 has an annular shape formed along the outer periphery of the glass panels 31 and 32, and the strength of the frame body 20 around the window portion 21 is secured by fixing the glass holder 33 to the frame body 20. Can contribute to improvement. Therefore, generation | occurrence | production itself of the said distortion etc. can be suppressed and the relative displacement function mentioned above can be exhibited suitably.

  When the glass unit 30 has the fixed front glass panel 31, it is possible to contribute to improving the strength of the glass unit 30 and consequently improving the strength of the front door 14. Even when the positional relationship between the frame 20 and the rear glass panel 32 changes, that is, when the movable rear glass panel 32 moves away from the window portion 21, the window portion 21 is blocked by the front glass panel 31. It will be maintained in a state of being peeled off. Thereby, unauthorized access to the game area PE through the window portion 21 and the boundary portion of the glass unit 30 and the frame body 20 can be suppressed. That is, while maintaining the positional relationship between the game board 80 and the glass unit 30 (specifically, the front glass panel 31), the strength reduction of the front door 14 and the decrease in crime prevention around the window portion 21 due to the positional relationship are suppressed. Can do.

  Moreover, by making the fixed front glass panel 31, the movable rear glass panel 32, and the glass holder 33 into a unit, it is possible to contribute to facilitating maintenance work and the like.

  In the present embodiment, by disposing the plate spring 57 as the urging means on the frame body 20 side, compared to the case where the urging means is disposed on the inner frame 13 side, the urging means and The expansion of the occupied area of the structure accompanying it can be suppressed.

  Also, if the biasing means is disposed on the inner frame 13 side, the rear glass panel 32 is separated from the game board 80 by the biasing means by moving the front door 14 to the closed position. Will be pushed forward. However, in such a configuration, when the front door 14 is closed vigorously, the rear glass panel 32 is moved to the game board 80 or the like before the movement of the rear glass panel 32 to the front limit position is completed. The possibility of interfering with cannot be wiped out. In this regard, if the urging means is disposed on the front door 14 side, the rear glass panel 32 can be kept waiting at the front limit position in advance, and the occurrence of the inconvenience can be suitably suppressed.

  When the rear glass panel 32 is urged by the leaf spring 57, it is preferable to place the leaf spring 57 close to the game area PE. However, it is not preferable that the game area PE or the like is pressed by this, and further, It is not preferable that the visibility of the game area PE is hindered by the leaf spring 57. Therefore, by adopting a configuration in which the leaf spring 57 is arranged between the portion not partitioned by the guide rail 100 on the front surface of the game board 80 and the rear glass panel 32, while ensuring the visibility of the game area PE, It can coexist suitably with the guide rail 100 on the front side of the game board 80.

  Moreover, the following effects can be expected by making the rear glass panel 32 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 rear glass panel 32 as described above, the game board 80, the game ball launching mechanism 110, It is possible to maintain the positional relationship between the rear glass panel 32 and the game board 80 while suitably maintaining the positional relationship. That is, compared with the case where the glass panel is fixed and the game board is movable, the above crime prevention effect and the like can be exhibited while suppressing the complication of the configuration.

  Further, the rear glass panel 32 is urged forward, and the extension portion 49 of the rear glass panel 32 comes into contact with the facing portion 450 of the game board 80, so that the rear glass panel 32 moves forward. The displacement is regulated. Thus, by setting it as the structure which prevents the movement of the rear side glass panel 32 ahead rather than relying on urging | biasing force mechanically, the said clearance gap maintenance function can be improved suitably, and the further crime prevention improvement is anticipated. it can.

  Further, the following effects can be expected as compared with the configuration in which the extending portion 49 faces the facing portion 450 from the front of the pachinko machine 10. That is, in such a configuration, the extension portion 49 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 rear side By biasing the glass panel 32 rearward, it is necessary to cause the extended portion 49 and the facing portion 450 to interfere strongly. In this case, in a normal time when the front door 14 is not lifted or the like, a larger urging force is applied to the extension 49 or the like than when the lift is generated. 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 49 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 above embodiment, the glass unit 30 has the front glass panel 31 as the “fixed panel portion” and the rear glass panel 32 as the “movable panel portion”. However, the present invention is not limited to this. It is not something. It is only necessary to have a configuration corresponding to at least the rear glass panel 32, and the front glass panel 31 can be omitted.

  However, when the front glass panel 31 is omitted, it is assumed that securing the rigidity of the front door 14 (particularly securing the rigidity around the window portion 21) becomes difficult. In particular, considering the fact that the front door 14 is rotatably supported by the inner frame 13, it is difficult to improve the rigidity in this way. The gap between the inner frame 13 and the front door 14 and the window portion 21. This is not preferable because the gap between the glass panel and the glass panel is likely to widen. Therefore, it is desirable to employ the front glass panel 31 from the viewpoint of improving crime prevention.

  (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 configuration 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 is different from that on the game board 80. There is a possibility that the positional relationship with the side glass panel 32 may be affected, and the function of maintaining the positional relationship between the game board 80 and the rear glass panel 32 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 49 of the rear glass panel 32 may be configured to contact the back surface of the game board 80. In other words, the extending portion 49 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 49 may be hooked to the back surface of the game board 80.

  (3) In the above embodiment, the opposing portion 450 of the second rail cover 400 provided on the game board 80 and the extending portion 49 provided on the rear glass panel 32 constitute a “regulating means”. Although the “regulating means” is arranged on the rotation base end side of the front door 14, it is not limited to this. 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 that can be switched between a locked state where the relative movement of the game board 80 and the rear glass panel 32 is disabled and an unlocked state where the relative movement of the game board 80 and the rear glass panel 32 is allowed. A device may be provided, and the locking device may 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-described embodiment, the rear glass panel 32 as the “panel portion” has a flat plate shape, but is not limited thereto. The rear side glass panel 32 can be formed in a curved plate shape. Furthermore, the material of the “panel portion” is not limited to glass, and a synthetic resin material may be used.

  Similar changes can be applied to the front glass panel 31.

  (5) In the above embodiment, the extending portion 49 as the “regulating means” is configured by a part of the rear glass panel 32, but is not limited thereto. For example, a synthetic resin rim may be integrally formed along the periphery of the glass panel, and a configuration corresponding to the extending portion 49 may be provided on the rim. That is, the restricting means of the rear glass panel 32 can be provided in a manner that can move integrally with the rear glass panel 32.

  (6) 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.

  (7) In the above embodiment, the plate spring 57 as the “biasing means” is attached to the front door 14 side, but the attachment target of the plate spring 57 is not limited to the front door 14. For example, the rear glass panel 32 can be urged forward of the pachinko machine 10 by a leaf spring attached to the inner frame 13.

  Incidentally, the leaf spring 57 is not an essential configuration and can be omitted. However, if the leaf spring 57 is omitted, even if the front door 14 is closed while the position of the rear glass panel 32 is varied, the extending portion 49 is located between the front surface of the game board 80 and the facing portion 450. It is preferable to provide a guide portion for guiding the extension portion 49 so as to be inserted therebetween. For example, when the one of the leading portion of the facing portion 450 or the leading portion of the extending portion 49 hits the other as the guiding portion, the extending portion 49 (rear glass panel 32) is used. A guiding inclined surface for guiding may be formed.

  Further, the “biasing means” is not limited to a leaf spring, and a coil spring, silicon rubber, or the like may be employed.

  (8) Although the glass unit 30 is screwed to the frame body 20 in the above embodiment, the attachment method is arbitrary as long as the glass unit 30 is fixed to the frame body 20. . 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, and the lock mechanism allows the glass unit 30 to be removed from the glass unit installation portion 22. It is good to prevent the dropout.

  Further, the front glass panel 31 as the “fixed panel portion” is not bonded to the glass holder 33 but can be fixed using other fixing means such as screws. Even when such a change is made, it is preferable to fix the front glass panel 31 to the holder structural bodies 33a and 33b. Moreover, if it fixes detachably using fixing means, such as a screw | thread, it can contribute to facilitation of maintenance work, such as when the part which each glass panel 31 and 32 has mutually opposed condenses.

  (9) In the above-described embodiment, the glass unit installation part 22 has a concave shape, and the glass unit 30 is accommodated in the glass unit installation part 22. However, the present invention is not limited to this. 22 may be omitted.

  (10) In the above embodiment, the plate springs 57 as “biasing means” are arranged on both the upper and lower sides across the extending portion 49, but the arrangement of the plate springs is arbitrary.

  (11) In the above-described embodiment, the extension portion 49 of the rear glass panel 32 abuts against the facing portion 450 of the game board 80 from the rear side, so that the rear glass panel 32 cannot be moved forward. It was set as the structure to do. The configuration in which the rear glass panel 32 cannot be moved forward is not limited thereto. For example, a configuration in which the extending portion 49 abuts against the facing portion 450 from the front is adopted, and a configuration in which the rear glass panel 32 is biased toward the game board 80 using a biasing means such as a leaf spring is used. As a result, the forward movement of the rear glass panel 32 can be suppressed.

  However, when such a change is made, the initial value of the urging force is increased so that the restriction function does not stop when the relative positional deviation between the rear glass panel 32 and the frame 20 becomes large. Need to set. 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 49 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 embodiment, the biasing force of the leaf spring 57 is also minimized when the relative position shift amount is minimum, and it is preferable to avoid an increase in the load generated in the extension portion 49 and the facing portion 450. be able to. Furthermore, when the change in the gap between the rear glass panel 32 and the game board 80 is very small, the contact between the extension portion 49 and the facing portion 450 can be avoided. It becomes possible to protect suitably. Therefore, desirably, as shown in the above embodiment, the extending portion 49 as the “restricting portion” on the rear glass panel 32 side is from the rear side with respect to the facing portion 450 as the “restricting portion” on the game board side. A configuration that abuts (opposes) 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 extending portion 49 constituting the “regulating means” is arranged between the rotation base end portion of the front door 14 and the operation port 83 as the “entrance portion”. The arrangement of the “regulating means” is arbitrary.

  It is also possible to arrange the “regulating means” between other pitching portions such as the general winning opening 81 and the rotation base end portion of the front door 14.

  (16) In the above embodiment, the glass holder 33 as the “holder part” is configured by combining the plurality of holder structural bodies 33a and 33b, but the number of holder structural bodies is not limited to two. . For example, the holder part can be formed by one member, or the holder part may be formed by combining three or more holder structures.

  Moreover, the holder part should just be what can hold | maintain the back side glass panel 32 at least as a "panel part", and does not necessarily need to form so that it may become cyclic | annular. For example, a holder using a plurality of independently provided frame members such as an upper frame member extending along the upper edge of the rear glass panel 32 and a lower frame extending along the lower edge of the rear glass panel 32. A part may be formed.

  (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 ease of 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 door frame (frame body 20) that covers the gaming machine main body from the front and that can be opened and closed with respect to the gaming machine main body and that has an opening (window portion 21) that exposes the gaming board to the front of the gaming machine. And a door body (front door 14) having a panel unit (glass unit 30) configured to cover the opening and to make the gaming area visible.
The panel unit has a panel portion (rear glass panel 32) facing the game board and a ring formed along the outer periphery of the panel portion, and a holder portion (glass holder 33) for holding the panel portion. And is integrated with the door frame by fixing the holder part to the door frame,
In the game board and the panel portion, when the door body is closed with respect to the gaming machine main body, a restricting means (rear glass panel 32 for restricting a change in the gap between the game board and the panel portion). Extending portion 49 and the facing portion 450) of the game board 80,
The gaming machine according to claim 1, wherein the panel portion and the holder portion are configured such that relative displacement in the front-rear direction is allowed at least in a state where the change of the gap is restricted by the restriction means.

  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 unit (specifically, 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 unit (specifically, the panel portion), and the game ball flows down the game area, the change in the relative position of the game board and the panel unit described above is in the game area. It can be a factor that affects the behavior of the game ball. In a gaming machine having a game board, since the advantage and disadvantage are determined by the behavior of the game ball in the game area, it is not preferable that the relative position of the game board and the panel unit change.

  In this regard, according to this feature, by restricting changes in the gap between the game board and the panel part by the restriction means provided on the panel part and the game board, the occurrence of the inconvenience is suitably suppressed, and the game area flows down. The behavior of the game ball can be made suitable.

  In addition, even if the positional relationship between the main body frame and the door frame changes due to the door frame floating from the main body frame, the panel portion and the holder portion (door frame) are relative to each other in the front-rear direction accordingly. By changing the position, the gap is maintained. Thereby, the dispersion | variation in the position of the game board and panel part resulting from the change of the positional relationship of a main body frame and a door frame can be suppressed, and the positional relationship of a game board and a panel part can be maintained suitably.

  In the configuration in which the door frame has an opening, there is a concern that the strength of the door body may be reduced around the opening. It is assumed that the relative displacement is likely to be hindered if the glass unit is affected by the distortion of the door frame due to the strength reduction. In this respect, in this feature, the glass portion is not directly fixed to the door frame, but is fixed to the door frame via a holder portion as an object of relative displacement. Thereby, the influence of the distortion or the like is suppressed. In particular, the holder portion has an annular shape formed along the outer periphery of the panel portion, and fixing the holder portion to the door frame can contribute to improving the strength of the door body around the opening. Therefore, generation | occurrence | production itself of the said distortion etc. can be suppressed and the relative displacement function mentioned above can be exhibited suitably.

  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 panel unit is mounted from the game board side with respect to the door frame,
The gaming machine according to claim 1, wherein the regulating means regulates an expansion of a gap between the gaming board and the panel portion.

  The change in the gap shown in the feature 1 etc. is not only caused by an accidental factor such as a variation in the assembly of the door body at the time of assembling a gaming machine, but it is an intentional factor such as intentionally shifting the position of the door body. It occurs in the same way. In a configuration in which the panel unit is mounted from the game board side, that is, from the back side of the door frame, it is difficult to pull the panel unit forward of the gaming machine (side away from the game board). For this reason, an improper tool such as a bar is inserted into the boundary portion between the door body and the gaming machine body, and the door body is lifted from the gaming machine body to widen the gap between the gaming board and the panel portion, so that a predetermined position in the gaming area ( For example, it is assumed that an action of generating a ball clogging is performed near the operation port 83 or the like. Such an action may cause inconvenience that the jammed game ball functions as a guide for winning, etc., and profits are illegally acquired.

  According to this feature, if the door frame is lifted from the main body frame as described above, the expansion of the gap between the game board and the panel portion is restricted by the restricting means. Thereby, it can contribute to the improvement of crime prevention.

Feature 3. The panel part is a movable panel part,
The panel unit is provided between the movable panel portion and the opening portion, and is provided with a fixed panel portion (front glass panel 31) fixed to the holder portion,
The gaming machine according to claim 2, wherein the opening is closed by the fixed panel portion.

  According to the feature 3, when the panel unit has the fixed panel portion, it is possible to contribute to the improvement of the strength of the panel unit and, consequently, the strength of the door body. Even when the positional relationship between the door frame and the movable panel portion changes, that is, when the movable panel portion moves away from the opening, the opening is maintained in a state of being blocked by the fixed panel. It will be. Thereby, unauthorized access to the game area through the opening and the boundary part of the panel unit and the door frame can be suppressed. That is, while maintaining the positional relationship between the game board and the panel unit (specifically, the fixed panel portion), it is possible to suppress a decrease in strength of the door body and a decrease in crime prevention around the opening due to the positional relationship.

  In addition, by making the fixed panel portion, the movable panel portion, and the holder portion into a unit, it is possible to contribute to facilitating maintenance work and the like. Moreover, in the structure which has two or more panel parts as mentioned above, it is preferable to hold | maintain the movable panel part so that attachment or detachment is possible by a holder part. Thereby, for example, when dew condensation or the like occurs in the facing portions of both panel portions, the panel portion can be easily cleaned.

Feature 4. Panel portion biasing means (plate spring 57) for biasing the movable panel portion toward the fixed panel portion side,
The holder portion is provided with a blocking portion (front wall portion 41) that prevents the movable panel portion from moving toward the fixed panel portion by contacting the movable panel portion from the fixed panel portion side. 4. The gaming machine according to feature 3, wherein

  As shown in feature 3, the door frame and the movable panel portion are allowed to move relative to each other, that is, when the expansion of the gap is restricted by the restricting means, the door frame can be displaced forward with respect to the movable panel portion. In the configuration, it is necessary to allow the rearward displacement of the movable panel portion with respect to the door frame. However, in such a configuration, when the door body is closed with respect to the gaming machine main body, if the movable panel portion is present at a position far from the fixed panel portion (position close to the game board), the same movement is possible. There is a concern that the panel will easily interfere with the game board. Particularly, since a game area is formed on the front surface of the game board, it is not preferable that such interference occurs. In this respect, if the movable panel portion is biased toward the fixed panel portion by the panel portion biasing means as shown in this feature, the movable panel portion is held at a position close to the fixed panel portion or the fixed panel. It can be moved to a position closer to the part. Thereby, the above disadvantages can be eliminated and a practically preferable configuration can be realized.

  Feature 5. The gaming machine according to claim 4, wherein the panel portion biasing means is disposed on the door body.

  According to the feature 5, by arranging the panel unit urging means on the door body, the panel unit urging means and the panel unit urging means and the gaming machine main body are arranged. The expansion of the occupied area of the structure accompanying it can be suppressed.

  If the panel urging means is disposed on the gaming machine main body side, the movable panel portion is separated from the game board by the panel portion urging means by moving the door body to the closed position. Will be pushed forward. However, in such a configuration, there is a possibility that the movable panel part may interfere with the game board or the like before the movement of the movable panel part to the fixed panel part side is completed when the door body is closed vigorously. Can not be wiped out. In this regard, if the panel unit urging means is disposed on the door body, the movable panel unit can be kept waiting in advance at a position close to the fixed panel unit, and the occurrence of the inconvenience can be suitably suppressed. it can.

Feature 6 The game board stands forward from the front surface of the game board, and forms a partition section (guide passage 103) for guiding the game area and the game ball to the game area on the front surface of the game board ( A guide rail 100),
6. The feature 4 or feature 5, wherein the panel portion biasing means is disposed between a portion of the front surface of the game board that is not partitioned by the partition portion and the movable panel portion. Gaming machine.

  When the panel unit is urged by the panel unit urging means, it is preferable to arrange the panel unit urging means close to the game area, but it is not preferable that the game area or the like is pressed by this, and further It is not preferable that the visibility of the game area is hindered by the panel portion biasing means. Therefore, if the panel portion urging means is arranged between the portion not partitioned by the partition portion and the movable panel portion on the front surface of the game board, the visibility of the game area is ensured while ensuring the visibility of the game board. It can coexist suitably with a division part on the front side.

  For example, when the game board has a substantially rectangular shape and the partition part has a substantially arc shape or a substantially annular shape, the panel unit urging means is disposed at a position near the corner of the game board. Good.

Feature 7. The door body is rotatably supported by the body frame,
The regulating means is
A game board side regulating portion (opposing portion 450) provided on the game board and facing the front surface of the game board with a predetermined gap;
Provided in the movable panel portion, the door body is inserted between the game board side regulating portion and the game board by rotating to a closed position with respect to the gaming machine main body, and the door body is the game It has a panel side regulation part (extension part 49) which separates from between the game board side regulation part and the game board by rotating to an open position with respect to the machine body. The gaming machine according to any one of features 4 to 6.

  According to the feature 7, it is switched to a restricted state in which the expansion of the gap is restricted by rotating the door body to the closed position, and is switched to a state in which the restriction is released by turning the door body to the open position. Can do. In this way, by eliminating the additional operation for causing the restricting means to function, it is possible to suppress complication of the opening / closing operation of the door body while enjoying the gap maintaining function.

  However, in such a configuration in which the panel side regulating portion provided in the movable panel portion is inserted and removed from the gap between the game board side regulating portion and the game board front surface, the front and rear positions of the movable panel portion vary. Therefore, it is assumed that the movement path of the panel side regulation part varies back and forth. If the gap between the game board side restricting portion and the front of the game board is set to be large in consideration of such variation in the movement path, it is assumed that the gap maintaining function is lowered. In this regard, as described in the feature 4 and the like, the above-described inconvenience is suitably wiped off by adopting a configuration that suppresses variation in the position of the movable panel portion at least when the door body reaches the closed position by the panel portion side biasing means. be able to.

Feature 8 A wall standing up from the front of the game board, and guiding means (guide rail 100) for guiding the game ball to the game area;
Features 1 to 7 characterized by comprising a launch rail (launch rail 112) provided on the main body frame for guiding a game ball launched from a game ball launcher (solenoid 111) to the guiding means. The gaming machine according to any one of the above.

  According to the feature 8, the game ball launched from the game ball launching unit reaches the game area via the launch rail → guide means. In a gaming machine in which a game board (specifically guiding means) and a launch rail are both provided in the main body frame, it is not preferable that the positional relationship between the game board and the launch rail changes. In this regard, if the configuration shown in feature 1 or the like is applied to the configuration shown in this feature, the change in the gap between the panel portion and the game board is regulated while suppressing the change in the relative position between the main body frame and the game board. be able to. That is, the positional relationship between the panel unit and the game board and the positional relationship between the game board and the launch rail can be suitably maintained, and a practically preferable configuration can be realized.

  In particular, in the combination with the feature 6, the “partition section” in the feature 6 and the “guidance means” in the feature can be the same.
