  A gaming board 3 is detachably attached to the gaming machine frame 2. In addition, at the upper position on the left side of the gaming machine frame 2 (left side when facing the front of the game board 3), a launch for launching the game ball 10 toward the game area 4 formed on the front of the game board 3 is performed. As shown in FIG. 2, the game ball 10 stored in the upper plate 11 is lifted to the launching device 30 below the launching device 30 on the rear side of the gaming machine frame 2. A lifting device 29 for supplying the game ball 10 is attached. Note that by providing the launching device 30 at the upper position on the left side of the gaming machine frame 2, the flying of the game ball 10 is more stable than when the launching device 30 is provided at the lower position on the left side of the gaming machine frame 2. In addition, although it has been described that the launching device 30 is provided at the upper position on the left side of the gaming machine frame 2, it is only necessary to be above the gaming area 4, and even above the gaming area 4, the upper position that does not overlap the gaming area 4. It may be the position.

  At the lower part of the upper plate 11, there is provided a guide inclined rod 10 a provided so that the game balls 10 stored in the upper plate 11 are aligned and supplied to the lower unit 29 a of the lifting device 29 described later. ing. In addition, the lower surface of the guide inclined rod 10a is an inclined surface that is gradually inclined downward toward the lifting device 29, and the game ball 10 that has flowed into the guide inclined rod 10a naturally flows down in the passage. ing.

  The game balls 10 stored in the upper plate 11 flow down the guiding inclined rod 10 a and are supplied to the lower unit 29 a provided at the lower part of the lifting device 29, and are sent to the launching device 30 by the lifting device 29. It is lifted and supplied, and is launched into the game area 4 of the game board 3 by the launching device 30. Further, the upper plate 11 and the lower plate 12 communicate with each other, and when the number of game balls stored in the upper plate 11 exceeds a certain number and becomes full, the balls exceeding the certain number are in the lower plate. Flow down to 12.

  As shown in FIG. 1, the launching device 30 is provided with a ball lift arm 33 and a launching arm 34 that are pivotally supported by a common swinging shaft inside the exterior case. One end of the ball lift arm 33 and the firing arm 34 is for a lift fixed coaxially to a cam shaft that is rotationally driven by a firing motor (not shown) fixed to the upper back side of the launching device 30. By slidingly contacting the cam 31 and the launch cam 32, the ball lift arm 33 and the launch arm 34 perform individual swinging motions as the lift cam 31 and the launch cam 32 rotate. The launch arm 34 is stretched below the launch device 30 so as to be substantially parallel to a launch rail 35 that is inclined so as to circumscribe the swinging arc of the ball lift arm 33 and the launch arm 34. The ball spring arm 33 is urged by a launch spring 36, and the ball lift arm 33 is urged by a lift spring 38 stretched so as to be substantially orthogonal to the launch spring 36. The firing rail 35 may be provided with the resin portion 500. When the resin portion 500 is provided on the launch rail 35, the launch rail 35 is inclined upward, and when the game ball 10 is launched by the launch arm 34, the game ball 10 is pressed against the launch rail 35 to play the game ball 10 and the resin portion 500. It is preferable to configure so that a high pressure is generated between them. For example, this can be realized by configuring the trajectory of the firing arm 34 to slightly intersect the surface of the firing rail 35 provided with the resin portion 500.

  The other end of the firing spring 36 that is not connected to the firing arm 34 is coupled to a slide piece 37 that is slidable in the extending direction of the firing spring 36. The urging force of the launch arm 34 is adjusted by sliding with a launch speed adjusting motor (not shown) fixed on the back side of the device 30, and the launch strength of the game ball 10 launched by the launch arm 34 is adjusted. The firing intensity is adjusted by controlling the operation of the firing speed adjustment motor by a firing control board (not shown) based on the operation of the operation knob 13.

  The launching operation of the launching device 30 will be briefly described. First, by the rotation of the launching motor, both the ball lift arm 33 and the launching arm 34 resist the urging force of the lift spring 38 and the launch spring 36. While being swung to the position of the lower corner of the launching device 30, in this state, one launching ball passes through the launching passage from the lifting device 29 and is provided on the rear surface of the outer case of the launching device 30. Is supplied through.

  The game ball 10 supplied to the launching device 30 is the same as the swing plane of the launch arm 34 that becomes the launch plane when only the ball lift arm 33 starts swinging by the rotation of the lift cam 31. On the plane, the ball lift arm 33 is guided to a predetermined firing position on the firing rail 35.

  A circular window through which a launch spring provided at the tip of the launch arm 34 can be inserted is formed at the swinging outer peripheral end of the ball lift arm 33, and the game ball guided to the launch position in the circular window. 10 is held. Further, the shape of the lift cam 31 is such that the outer diameter thereof is greatly increased so that the moving speed of the swinging lower end of the ball lift arm 33 is increased in the region far from the launch position, and the ball lift is increased in the vicinity of the launch position. The outer diameter of the arm 33 is slightly increased so that the guiding speed of the gaming ball 10 guided by the moving speed of the lower end of the swing of the arm 33 becomes low.

  Next, the game ball 10 guided to a predetermined launch position on the launch rail 35 is released from the force against the launch spring 36 as the launch cam 32 rotates, so that the launch spring 36 is released. By swinging the launch arm 34 with a momentum proportional to the biasing force due to, the game arm 4 is launched through the launch path on the launch rail 35.

  At this time, the game ball 10 that has not reached the game area 4 due to the low momentum of launch flows down on the launch rail 35 to the inclined lower side, but flows into the foul ball channel (not shown), It is returned to the upper plate 11 or the lower plate 12 through a discharge passage 25 from a foul ball outlet (not shown) formed at the lower end of the foul ball channel. The foul ball may return to the upper plate 11 or the lower plate 12 through a path different from the payout path 25.

  The game ball 10 launched into the game area 4 through the launch path on the launch rail 35 is changed in the moving direction along the rail 4a in the game area 4, and the starting electric player 6, the attacker 7 and the out port of the game area 4 Recovered from. The rail 4 a that changes the moving direction of the game ball 10 is provided with a resin portion 500 that improves the lubricity of the game ball 10. That is, the resin portion 500 is provided at a position that promotes shaving compared to the conventional case. The lubricity of each game ball 10 to be launched can be enhanced by the resin portion 500 provided on the rail 4a. The resin part 500 is fixed to the rail 4a by locking means 500a such as screwing or claw locking, and is detachable from the rail 4a. A plurality of resin portions 500 are provided to cover part or all of the rail 4a. The resin portion 500 is a fluorine resin such as polytetrafluoroethylene or polytetrafluoroethylene.

  When the rail 4a is covered with a plurality of resin parts 500, the flow of the game balls 20 launched at the joint portions of the resin parts 500 is obstructed, and the malfunction of the resin parts 500 being chipped by the game balls 20 that are launched is prevented. Therefore, for example, the corner of the resin part 500 on the side close to the flow of the game ball 20 is thinner than the corner of the resin part 500 on the opposite side. Further, the resin portion 500 may have an obtuse angle on the side closer to the flow of the game ball 20 than the angle on the opposite side. Furthermore, in order to prevent the corners of the resin part 500 provided on the rail 4a from hanging down from the rails 4a due to its own weight, a configuration may be provided in which locking means 500a is provided in the vicinity of the corners of the resin part 500. Further, the resin part 500 is not limited to the structure that is fixed to the surface of the rail 4a by using the locking means 500a. For example, the resin part 500 may be fixed so that a gap is provided in the rail 4a and pressed against the gap from the back surface of the rail 4a. Good. When the resin part 500 is fixed to the back surface of the rail 4a, a part of the resin part 500 is exposed from the gap of the rail 4a, and the game ball 10 comes into contact with the exposed resin part 500, thereby improving the lubricity of the game ball 10. be able to.

  Since the moving direction of the game ball 10 is changed by the rail 4a, the game ball 10 is pressed with a strong force against the resin portion 500 provided on the rail 4a. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10. Although FIG. 1 shows an example in which the resin portion 500 is provided on the rail 4a, any position may be used as long as the movement vector (direction and speed) of the game ball 10 can be changed. .

The configuration of the game area 4 in which the game ball 10 has been launched will be described with reference to FIG.
Near the upper center of the game area 4, a variable display device 5 for variable display of a plurality of types of identification information called “decorative symbols” is provided, and a “normal symbol” is displayed on the left side of the game board 3 toward the front. A normal symbol display 9 for displaying individual symbols (designed by 7-segment LEDs in the present embodiment) is provided. In the present embodiment, the variable display device 5 is formed by an LCD display (liquid crystal display), and the decorative design can be variably displayed.

  Further, the normal symbol display 9 has 7 segment LEDs, and the decorative symbol displayed on the variable display device 5 is variably started based on the starting ball winning to the starter combination 6 as will be described later. The On the other hand, the normal symbol displayed on the normal symbol display 9 is changed based on the hit ball passing through the gate 8 as will be described later.

  On the left side of the game board 3 facing the front, a gate 8 for guiding a hit ball is provided. The gate 8 includes a gate switch 217 that detects a hit ball that has passed through the gate 8.

  Further, the starter combination 6 is provided with a movable piece 61, which is opened by a starter solenoid (not shown), and the start winning ball that won the starter combination 6 is led to the back of the game board 3. This is detected by the start winning a prize opening switch 216.

  Also, an attacker 7, which is a variable winning ball device provided with an opening / closing plate, is attached below the starter role 6. When the gaming state becomes a big hit state (specific gaming state), an opening / closing plate is opened by an attacker solenoid (not shown), and a big winning opening of the attacker 7 is opened. A winning ball that has entered the big winning opening is detected by a winning ball detection switch (not shown).

  The game board 3 is provided with a plurality of winning holes (not shown). Decorative lamps (not shown) that are lit and displayed during the game are provided around the left and right sides of the game area 4, and at the lower part, an outlet that collects a hit ball that has not won any winning hole as an out ball Is provided.

  Although not shown in FIG. 1, two speakers that emit sound effects are provided on the left and right upper portions outside the game area 4, and a game effect lamp is provided on the outer periphery of the game area 4. ing. A winning ball lamp (not shown) is provided in the vicinity of one of the speakers and is turned on when the winning ball is paid out. Not shown).

  A hit ball fired from the launching device 30 by operating the operation knob 13 enters the game area 4 and flows down the game area 4. When the hit ball is detected by the gate switch 217 through the gate 8, the normal symbol stopped and displayed on the normal symbol display 9 is variably started. If the hit ball passes through the gate switch 217 during variable display of the normal symbol display 9, the passage is memorized, and the normal symbol display 9 stops and passes after it is ready to start changing again. The normal symbol display 9 is variably controlled by subtracting “1” from the memory. The upper limit of the passing memory is set to “4”, for example, and the current passing memory number is displayed by a passing memory display (not shown).

  Further, when the hit ball wins the starter role 6 and is detected by the start winning port switch 216, the decorative symbol displayed on the variable display device 5 starts scrolling if the variation of the decorative symbol can be started. For example, if the variable display is already started and the decorative symbol is changing, and the variation of the decorative symbol cannot be started immediately, the start winning memory is increased by one. In this embodiment, with an upper limit of four, every time a start prize is stored, one additional LED of a start prize storage display (not shown) is lit. Each time the variable display device 5 starts variable display of decorative symbols, one LED is extinguished.

  When the display result after the variable display operation of the normal symbol display 9 becomes a predetermined specific display result (for example, a number corresponding to “7” is lit), the movable provided in the starter role 6 The piece 61 is opened for a predetermined time, and the game ball 10 is in an advantageous state for the player who can easily win the starter combination 6.

  If the game ball 10 wins the starter role 6 and is detected by the start winning port switch 216, the decorative symbol can be variably displayed on the liquid crystal display screen of the variable display device 5 if the variation of the decorative symbol can be started. (Fluctuation display) starts. After that, when the variable display is stopped and the result of the stop display becomes a predetermined specific display mode (for example, 777), a specific gaming state (big hit state) occurs.

  When the big hit state occurs in this way, the opening / closing plate of the attacker 7 is opened, and a first state advantageous to the player is obtained. This first state ends when a predetermined period (for example, 30 seconds) has elapsed or a predetermined number of hit balls (for example, 10) wins, whichever comes first, and then for the player This is a disadvantageous second state. In this embodiment, the repeated continuous control in the first state can be executed up to 15 times. Such a time when the first state that can be executed 15 times at maximum is called a round of repeated continuation control. In this example, the repeated continuation control can be repeatedly executed from the first round to the maximum 15th round. In addition, as a special symbol display (not shown) that variably displays a special symbol separately from the variable display device 5, for example, a 7-segment LED is provided, and the special symbol indicator is interlocked with the start and stop of decoration symbol variation. The special symbol may be variably displayed at.

  The resin part 500 may be provided on the back side of the opening / closing plate of the attacker 7. By providing the resin portion 500 on the back side of the opening / closing plate of the attacker 7, when winning the attacker 7, the game ball 10 collides with the back side of the opening / closing plate of the opened attacker 7, and the game ball 10 and the resin portion 500 are Since a high pressure is applied during this period, the resin portion 500 can be slightly scraped off and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10. When the resin part 500 is provided on the back side of the opening / closing plate of the attacker 7, the game ball 10 collides with the resin part 500 only during the big hit, so that the lubricity of the game ball 10 is not excessively increased. In addition, in the case of a gaming machine in which the player has an advantage by aiming at the right area of the game area 4 during the big hit, by providing the resin portion 500 in a place where the game ball 10 is likely to collide in the right area of the game area 4, Since the game ball 10 collides with the resin part 500 during the big hit, the lubricity of the game ball 10 can be improved.

  Further, when the decorative symbol variably displayed on the variable display device 5 is stopped and displayed with a big hit symbol that matches the same symbol type, a big hit is generated as described above. When the symbol is displayed, a probability variation state (hereinafter, also referred to as a probability variation state) in which the probability of generating a big hit is higher than that in the normal gaming state is varied. A special display mode jackpot symbol that triggers the occurrence of such a probability variation state is called a probability variation symbol. Hereinafter, the jackpot generated by the probability variation symbol is referred to as a probability variation jackpot, and is distinguished from the normal jackpot which is a jackpot generated by a jackpot symbol other than the probability variation symbol (non-probability variation symbol).

  Once a probability variation jackpot occurs in the normal gaming state, the probability variation state is, for example, a probability variation state until a jackpot for at least a predetermined number of probability variation continuations (for example, once or twice) occurs. Is continuously controlled. Further, if a probability variation big hit occurs during the probability variation state, the probability variation continuation count is counted again after that probability variation big hit, and then the probability variation state continues until at least the number of probability variation continuations occurs. If the jackpot that has reached the probability variation continuation count is due to a non-probability variation symbol other than the probability variation symbol, the normal gaming state in which the probability variation does not occur is returned.

  In the variable display device 5, a reach state may occur. Here, the “reach state” is a display that becomes a specific display mode even after the variable display device 5 is variably started and before the display control progresses and reaches a stage before the display result is derived and displayed. A display mode that does not deviate from the conditions. In other words, reach means a display state for making a player think that a combination of specific display modes is easily displayed at a stage where the display result of the variable display device 5 has not yet been derived and displayed. Say. For example, a state in which variable display by the variable display device 5 is performed while maintaining a state in which specific combinations of display modes are maintained is also included in the reach display state. Furthermore, some reach is likely to generate a big hit when it appears, compared to normal reach (normal reach). Such a specific reach is called super reach.

  The reach state is a display state at the time when the display control of the variable display device 5 progresses to reach a stage before the display result is derived and displayed, and before the display result is derived and displayed. It also refers to a display state in a case where at least some of the display results of the determined variable display areas satisfy the conditions for the specific display mode.

  On the back side of the game board 3, an effect control board (not shown) for performing display control of the variable display device 5, a game control board (not shown) on which a game control microcomputer and the like are mounted are provided. ing. Further, on the back side of the game board 3, a launch control board (not shown) on which a microcomputer for controlling the operation of the launch device 30 is mounted is provided. The gaming machine frame 2 is provided with a payout control board (not shown) on which a payout control microcomputer for performing payout control of the game ball 10 is mounted.

  Next, the lifting device 29 that supplies the game ball 10 to the launching device 30 will be described with reference to FIG. The gaming machine 1 is a type of gaming machine in which a launching device 30 is provided at an upper position on the left side (left side as viewed from the front of the game board 3), and a game ball 10 is launched from the upper launch position of the game area 4. Therefore, it is necessary to provide a lifting device 29 for lifting the game ball 10 from the position of the upper plate 11 to the upper launching device 30 on the back surface of the gaming machine 1.

  Therefore, in the gaming machine 1 of the present embodiment, the ball tank 103 is disposed at the position on the opposite side where the lifting device 29 is disposed, and the upper position on the right side (right side when facing the front of the game board 3). In the gaming machine 1 of the present embodiment, the ball payout device 225 is provided between the ball tank 103 and the lifting device 29. Here, the ball tank 103 is a standby unit for waiting the game ball 10 supplied from the replenishment basket 100 via the branching unit 101 and the supply pipe 102, and the game ball 10 is paid out from the ball payout device 225. It prevents you from running out of time. As will be described later, a resin portion 500 is provided on the bottom surface of the ball tank 103. The bottom surface of the ball tank 103 is a surface on which a plurality of game balls 10 can be stacked. By providing the resin portion 500 on the bottom surface, the game ball 10 can be pressed against the resin portion 500 with a force greater than its own weight. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10.

  The ball payout device 225 is provided at a lower position on the right side (right side in FIG. 2) of the ball tank 103. When the game ball 10 to be paid out to the gaming machine 1 is generated by winning or pressing down the lending button 17a, the ball payout device 225 uses the guide rod 104 to draw the game ball 10 waiting in the ball tank 103 to the payout path. 25 is a device that pays out to the upper plate 11 via 25. A sprocket (not shown) for paying out balls one by one and a payout motor (not shown) for driving the sprocket are provided inside the ball payout device 225. The payout motor is driven by the control of the payout control board. When the payout motor is driven, the sprocket rotates, and the game balls 10 in the ball payout device 225 are sent to the payout passage 25 one by one by the sprocket. The game ball 10 paid out through the payout passage 25 is supplied to the upper plate 11 from a payout outlet 251 provided at the lower end of the payout passage 25.

  Next, the lifting device 29 will be described in detail. The lifting device 29 includes a lifting screw 291 as a lifting member for lifting the game balls 10 separated one by one, a lifting path case 290 in which the lifting screw 291 is housed, A drive unit 292 for driving the lifting screw 291 provided below the lifting path case 290 and a game ball 10 lifted by the lifting screw 291 and supplied to the launching device 30 A lifting outlet 293 is included. Further, the lifting device 29 includes a return passage 26 for returning the game ball 10 in the device, and guides the game ball 10 in the device to the return passage 26 by pressing the return operation button 14 as will be described later. The game ball 10 is returned to the lower plate 12 from the return port 261 provided at the lower end of the return passage 26.

  Further, an upper lifting sensor (not shown) is provided in the vicinity of the lifting outlet 293, and a lower lifting sensor 221 is provided between the guide inclined rod 10 a and the lifting screw 291 in the upper plate 11. The upper lifting sensor and the lower lifting sensor 221 are sensors for detecting the presence or absence of the game ball 10 in the lifting screw 291, and games that have entered the lifting screw 291 from the upper plate 11 by the lower lifting sensor 221. The presence or absence of the game ball 10 in the lifting screw 291 is detected by counting the number of gaming balls that have been emitted from the lifting outlet 293 by the upper lifting sensor.

  The gaming machine 1 described above is configured to supply game balls from the game island and collect the game balls on the game island after the game. However, the gaming machine according to the present invention may be an enclosed type in which game balls circulate in the gaming machine, and the enclosed gaming machine will be described below. In the encapsulated gaming machine described below, the case where the launching device is provided at the lower position on the right side of the gaming machine will be described. However, like the gaming machine 1 shown in FIG. You may provide in the upper left position.

  FIG. 3 illustrates an aspect in which the circulation path of the game balls is viewed from the back of the game machine 1 on the lower side of the game area in the game machine 1. With reference to FIG. 3, the circulation path of the enclosed circulation type game ball 10 will be mainly described. In the enclosed circulation type gaming machine 1, the game balls 10 launched into the game area by the launching device are collected from the collection path, and the game balls 10 are supplied to the launching apparatus by returning to the supply path.

  The game ball 10 that has been thrown into the game area is won at any of the winning openings or is collected at the out opening 145 without winning. Specifically, all winning balls (safe balls) won from a winning opening provided in the game area or a variable winning ball device are detected by a winning ball detection switch (not shown) and a winning ball collective cover is provided. Collected by the member 144, passes through the safe ball flow path 706, and is guided to the collection ball passing path 901. In the safe ball flow path 706, the resin portion 500 is provided at a position where the safe balls collected by the winning ball collecting cover member 144 fall on the safe ball flow path 706. Therefore, when the safe balls collected by the winning ball collective cover member 144 flow into the safe ball flow path 706, the movement vector of the safe ball (the game ball 10) is changed by colliding with the surface provided with the resin portion 500. . Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10. Similarly, the resin portion 500 is provided at a position where the game ball 10 that has passed through the safe ball flow path 706 falls into the collection ball passage path 901. Even if the resin portion 500 is provided on the surface on which the plurality of game balls 10 can be stacked in the collection ball passage route 901, a surface for changing the movement vector of the game ball 10 in the middle of the post-merging ball passage route 707 (fired ball detection The resin portion 500 may be provided in the vicinity of the switch 903. Moreover, it is preferable to provide the resin part 500 in the position where several path | routes merge, or the downstream position. Since this position is a position where many game balls 10 flow, there is a high possibility that a plurality of game balls 10 can be stacked, and the lubricity of the game balls 10 can be improved.

  On the other hand, the out ball that has entered the out port 145 flows down the out ball flow path 702 and is guided to the collection ball passing path 901. The out ball flow down path 702 is provided with an out ball detection switch 701 (out game medium detecting means), and a ball flowing down the out ball down flow path 702 is detected. Further, the foul sphere flows down the recovery sphere passing path 901 through the foul sphere return path 902. A foul ball detection switch 33A (foul game medium detecting means) for detecting a foul ball flowing down is provided in the middle of the path through which the foul ball passes. Therefore, all of the safe sphere, the out sphere, and the foul sphere finally enter the collecting sphere passage route 901 and join together, and thereafter flow down the sphere passage route 707 after joining. An example of the path through which the safe ball, the out ball and the foul ball pass is indicated by arrows in FIG. 2, and the game ball flow in the figure is all the game balls after the safe ball, the out ball and the foul ball have joined. Shows the common flow. Note that the position at which the game ball 10 that has flowed down the out-ball flow path 702 falls into the collection ball passage path 901, or the position at which the game ball 10 that has passed through the foul ball return path 902 flows down to the collection ball passage path 901 (safe ball flow path). The resin portion 500 is provided at a position common to the position at which the game ball 10 that has passed through 706 falls on the collection ball passage route 901.

  A launch ball detection switch 903 is provided in the middle of the post-merging ball passage route 707, and all the game balls 10 in which the winning ball, the out ball, and the foul ball merge are detected. Further, 50 replenishment detection switches (also referred to as game ball shortage detection switches) 904 are provided in the middle of the shot ball detection switch 903 on the downstream side. The 50 replenishment detection switch 904 is for detecting whether or not the number of game balls 10 built in the gaming machine 1 has reached a specified number (50). On the other hand, the above-mentioned shot ball detection switch 903 collects and detects all of the game balls 10 that have been shot into the game area, and detects the number of shot balls that have been shot into the game area and this shot ball detection. When the number of game balls 10 detected by the switch 903 becomes equal, it is detected that all the game balls 10 that have been thrown into the game area have been collected.

  The fired ball detection switch 903 having such a role is also used for detecting that the number of encapsulated balls built in the gaming machine 1 exceeds a specified number (50). That is, when the number of game balls 10 sealed in the gaming machine 1 is a prescribed number (50), the last 50th game ball of the sealed balls that are stopped in a non-operating state where no game is performed. The position of 10 is configured to be located just between the 50 replenishment detection switch 904 and the shot ball detection switch 903. Thereby, when the game balls 10 exceeding the specified number (50) are encapsulated in the gaming machine 2, the game balls 10 that are stopped in a state where no game is played exceed the detection position of the launch ball detection switch 903. The launch ball detection switch 903 is always in a sphere detection state, and it is possible to detect that the number of encapsulated spheres is too large. Specifically, the detection signal of the shot ball detection switch 903 is input to the payout control unit provided in the gaming machine 1, and the payout control unit detects a ball for a specified time (for example, 2 seconds) or more based on the detection signal. When it is determined that the continuous detection state is being performed, it is determined that the enclosed game ball 10 is in an excess state. That is, the position where the shot ball detection switch 903 is arranged and the collection ball passage route 901 upstream thereof are the stopping route portion of the game ball 10 exceeding the specified number. Therefore, the shot ball detection switch 903 includes a number detection unit that detects the game ball 10 collected in the circulation path after being used in a game, and a continuous detection in which the number detection unit detects a game medium continuously for a predetermined time or more. When it becomes a state, it is used also as the excess detection means used in order to determine with the excess state of the enclosed game ball 10.

  Further, the payout control unit issues an alarm when it is determined that a ball having a specified time (for example, 2 seconds) or more is being detected. And the surplus ball which the attendant of the game hall has manually exceeded is extracted. Instead of this manual extraction, the payout control unit may control the driving of a ball removal motor 931 (see FIG. 7) to automatically remove excess excess balls. Instead of or in addition to the alarm notification described above, error notification may be performed by a display.

  Further, when a shortage of balls is detected by the 50 replenishment detection switch (also referred to as a gaming ball shortage detection switch) 904, an alarm for prompting the refilling of the gaming balls 10 is notified. Instead of or in addition to this alarm notification, error notification may be performed by the display unit 54.

  The payout control unit includes a CPU (Central Processing Unit) as a control center, a ROM (Read Only Member) that stores a control program, control data, and the like, and a RAM (Random Access Memory) that functions as a work area of the CPU. ), I / O ports and the like.

  On the other hand, when the number of encapsulated balls is less than the specified number (50), the game ball 10 that is stopped in the non-game state is located downstream of the detection position of the 50 supply detection switch 904 and is supplied. The 50 detection switches 904 are in a non-detection state where no sphere is detected. As a result, it is possible to detect that the number of encapsulated spheres is less than the specified number (50).

  In the above circulation path, the above-mentioned winning ball detection switch, out ball detection switch 701 and foul ball detection switch 33A detect the numbers of safe balls, out balls and foul balls, respectively. The detection signals of these switches and the detection signal of the launch ball detection switch 903 are input to the above-described payout control unit. In the payout control unit, the total number of safe balls (winning balls), out balls and foul balls, It is determined whether or not the number of game balls 10 detected by the ball detection switch 903 matches. Specifically, the CPU of the payout control unit determines “safe ball (winning ball) + out ball + foul ball = number of game balls 10 detected by the launch ball detection switch 903”. In this way, the payout control unit determines whether the total number of safe balls (winning balls), out balls, and foul balls is the same as the number of game balls 10 detected by the launch ball detection switch 903. Judgment means for judging is provided.

  FIG. 4 illustrates an aspect in which the circulation path of the game balls is viewed from the front of the gaming machine 1 on the lower side of the gaming area in the gaming machine 1. With reference to FIG. 4, the structure of the circulation mechanism of the enclosed circulation type game ball 10 will be described in more detail.

  In addition to the above-mentioned circulation mechanism on the lower side of the game area, mainly the ball collection path 189, the polishing member 913, the ball raising switch (lower) 41b, the ball raising switch (upper) 41a, the discharge guiding portion 915, The rectifier 916, the slide member 170, and the ball removal box 173 are disposed. Detection signals from the ball raising switch (lower) 41b and the ball raising switch (upper) 41a are input to the aforementioned payout control unit. The ball collection path 189 is a circulation path of the collected game balls 10 described above, and is equivalent to, for example, the post-merging ball passage path 707 in FIG.

  The game ball 10 that has flowed down the ball collection path 189 enters a transfer device (not shown) for transferring the game ball 10 upward. More specifically, the transport device incorporates a transport screw that is rotated by a transport motor, and the game ball 10 is transported upward by the rotation of the transport screw. The transfer device is further provided with a polishing member 913 for polishing the game ball 10 by contacting with the game ball 10 being transferred, and the surface of the game ball 10 is polished while being transferred upward. The The carry motor is connected to the payout control unit, and the carry motor is driven and controlled by a control signal from the payout control unit. The polishing member 913 has a columnar shape and is arranged such that its longitudinal direction extends in the vertical direction of the game ball 10. The polishing member 913 has, for example, a buff main body portion and a surface mesh portion that covers the surface of the buff main body portion. The buff body is a columnar member formed from a porous member such as a sponge. However, the buff main body is not limited to a sponge, and for example, any material that can take in dirt and the like removed from the surface of the game ball 10 by polishing the surface of the game ball 10 can be used. As an example, a buff main body portion made of a paper-like member may be used.

  A ball raising switch (lower) 41b is provided in the vicinity of the game ball inlet of the transfer device, and the game ball 10 entering the transfer device is detected. On the other hand, the game ball 10 transported upward by the transport device and discharged from the transport device is detected by the ball raising switch (upper) 41a. When the detected game ball 10 is supplied again to the ball launch position and driven into the game area, the game ball 10 is guided to the ball launch position by the rectifier 916. The rectifier 916 includes a solenoid (also referred to as a rectifier solenoid) 196a. The solenoid 196a is connected to the payout control unit, and is excited and controlled by a control signal from the payout control unit. When the player operates the hitting operation handle 13, the hitting motor 18 is driven and the hitting hammer is intermittently swung. One game ball 10 that has been supplied to the launch position by the rectifier 916 is ejected by the hitting hammer, and the game ball 10 is driven into the game area through the inner rail and the outer rail. In addition, the lubricity for every game ball 10 to be fired can be improved by providing the resin portion 500 at a portion where the game ball 10 is supplied to the launch position by the rectifier 916.

  When the game ball 10 is supplied to the launch position by the rectifier 916, the game ball 10 located on the ball raising switch (upper) 41a disappears, so the ball raising switch (upper) 41a is temporarily turned off (non-detection state). However, the game ball 10 lifted by the transfer device is supplied, and the ball raising switch (upper) 41a is turned ON (detected state) again. Therefore, during hitting, the detection signal of the ball raising switch (upper) 41a is repeatedly turned ON and OFF, and the payout control unit counts the detection signal and counts the number of shot balls. Further, the payout control unit also counts the number of collected shot balls based on the detection signal of the shot ball detection switch 903. The payout control unit monitors the difference between the number of shot balls and the number of shot balls collected. When the difference is equal to or greater than a predetermined number (30), the payout control unit determines abnormality and performs control such as error notification. Specifically, the CPU of the payout control unit determines “number of fired balls−number of collected shot balls ≧ 30”, and determines an abnormality when the determination result is YES. In addition, when the payout control unit determines that there is an abnormality, in addition to or instead of the error notification, the firing may be stopped and the game prohibited state may be controlled. In addition, the host server may be notified via the card unit that an abnormality has occurred. Then, control such as error notification may be performed by the host server. Furthermore, the abnormality determination may be performed by the card unit instead of the payout control unit. Further, a predetermined number (30 threshold values) for determining whether or not there is an abnormality may be variably set.

  In FIG. 4, the hitting ball launch motor 18 and the hitting hammer are arranged below the gaming machine 1 (in the game area 4), and the ball 10 that has been ejected is guided upward by the inner rail and the outer rail. Fires into the gaming area from the upper side of the area. However, the ball hitting motor 18 and the ball hitting hammer may be arranged on the side of the upper part of the game area, and the game ball 10 may be directly shot into the game area from there. In the case of such a top-type pachinko machine, the ball launch position is on the upper side of the game area. A general under-coating type in which a game ball 10 that is bulleted from below (in a game area) of a pachinko machine is guided upward by an inner rail and an outer rail and is fired into the game area from the upper side of the game area. In the case of a pachinko machine, the bullet ball 10 passes through the stainless steel launch rail, the inner rail and the outer rail, and therefore passes through the stainless steel rail for a long distance, and the ball is contaminated. However, in the case of a top-type pachinko machine, the distance traveled by the stainless steel rail is shortened, and dirt is less likely to adhere to the ball.

  On the other hand, when the game ball 10 detected by the ball raising switch (upper) 41 a is discharged to the outside of the gaming machine 1, the game ball 10 is introduced toward the discharge guide portion 915 and flows down toward the slide member 170.

  Next, an apparatus for discharging the game ball 10 to the outside will be described with reference to FIGS. Referring to FIG. 5, when the game ball 10 whose surface is polished by the polishing member 913 is driven into the game area again, the ball launching position by the rectifier 916 (see FIGS. 7A and 7B). To be introduced. At this time, the game ball 10 is supplied to the launch point by the solenoid 196a in synchronization with the sensor signal of the hit ball launch motor 18.

  On the other hand, when the game ball 10 whose surface has been polished by the polishing member 913 is to be discharged to the outside of the gaming machine 1, a game attendant operates a ball removal switch provided on a relay board (not shown). As a result, the ball removal motor 931 rotates by a predetermined amount, and the enclosed ball can be extracted out of the path. Referring to FIG. 4, this relay board is provided at a position below foul ball return path 902. The game ball 10 is discharged from a discharge guiding portion 915 serving as a discharge port, and flows toward the slide member 170 (a switching member included in the path switching unit). The slide member 170 has a drop port 171 and a guide portion 172. A ball removal box 173 (game medium box) is disposed at a box mounting portion below the slide member 170. The ball removal box 173 is a box for collecting and storing the game ball 10 whose surface is polished to be discharged to the outside of the gaming machine 1. Referring to FIG. 3, a hook for mounting (not visible in the drawing) is provided on the front side (player side) of the ball removal box 173, and the front side (player side) of the ball removal box 173. The hook is locked to a hook locking portion (box mounting portion) formed on the member positioned at, and the ball removal box 173 is attached.

  When the slide member 170 is disposed at a predetermined position (first position), the drop port 171 guides toward the extraction portion for receiving and extracting all the game balls 10 discharged from the discharge guide portion 915. In addition, the path is dropped into the ball removal box 173 and is a cylindrical passage extending in the vertical direction of the gaming machine 1. When the slide member 170 is disposed at a predetermined position, the guide unit 172 receives the game ball 10 that has reached the discharge guide unit 915 and guides it to the front side of the ball removal box 173 serving as a service game medium extraction unit. This is a slope-shaped passage for taking the game ball 10 out of the gaming machine 1.

  When the game balls 10 are introduced into the ball removal box 173 through the drop mouth 171, all the game balls 10 existing in the circulation path are discharged to the ball removal box 173. The mode in which the game ball 10 is discharged from the discharge guiding portion 915 to the ball removal box 173 in this way is referred to as a ball removal mode (first state) here.

  On the other hand, the game ball 10 is taken out to the front side of the ball removal box 173 through the guide portion 172 (the game ball 10 taken out in this way is called a service ball), so that a single game ball 10 is obtained. Is discharged outside the gaming machine 1 as a service ball. A mode in which the game ball 10 is discharged by guiding the discharge guide unit 915 in the direction of the take-out unit to be taken out as a service ball is referred to as a service ball mode (second state).

  The slide member 170 is a switching member that can switch its position by sliding in the gaming machine 1 from the upper left in the drawing to the lower right (left and right in FIG. 3). Specifically, for example, the position of the slide member 170 includes the normal position, the position in the ball removal mode (first position), the position in the service ball mode (second position), and the ball removal box 173 itself. It is possible to switch to four stages of positions to be removed from the box mounting portion of the gaming machine 1. From the left side to the right side of FIG. 4 (that is, when the gaming machine 1 is viewed from the front side to the right side) in the order of the normal position, the position in the ball removal mode, the position in the service ball mode, and the position to remove the ball removal box 173 F) The position of the slide member 170 is switched.

  Here, the normal position means the position of the slide member 170 when the game ball 10 launched from the ball raising switch (upper) 41b is supplied again to the ball launching position. FIG. 5 shows a mode in which the slide member 170 is arranged at the position in the ball removal mode, and FIG. 6 shows a mode in which the slide member 170 is arranged at the position in the service ball mode. FIG. 5 corresponds to the first state described above, and is a state in which the game ball 10 that has reached the discharge guiding portion 915 enters the ball removal box 173 from the drop port 171 and is discharged to the outside of the gaming machine 1. FIG. 6 corresponds to the second state described above, and shows a state in which the game balls 10 that have reached the discharge guiding unit 915 are discharged from the guide unit 172 one by one as service balls to the outside of the gaming machine 1. Further, it becomes possible to move the ball-out box 173 upward at a position (not shown) where the slide member 170 removes the ball-out box 173, and the above-described mounting hook is pulled out from the hook engaging portion. Thus, it becomes possible to release the ball release box 173 by releasing the lock. Note that the switching of the position of the slide member 170 is not limited to four stages, and may be three stages. For example, the slide member 170 is normally at a position for taking out the service ball, and from that state, the position is switched to three stages: a position in the ball removal mode, and a position in which the ball removal box 173 itself is removed from the box mounting portion of the gaming machine 1.

  Referring to FIG. 6, it is preferable that a receiving tray 174 for receiving a service ball is disposed on the downstream side of guide portion 172. For example, when the receiving tray 174 is not provided on the downstream side of the guide portion 172 as shown in FIG. 5, it is necessary to receive the service ball from the guide portion 172 by hand in the service ball mode. However, by providing the receiving tray 174, the service ball can be received. In order to hold about 4 service balls discharged from the circulation path of the balls, for example, the service sphere is blocked by the guide 172 by gently curving the guide 172 in the left-right direction in FIG. It is good also as a structure. Further, the resin portion 500 is provided at a position where the game ball 10 that has reached the discharge guiding portion 915 falls on the guide portion 172. Therefore, when the service ball is taken out, the movement vector of the service ball (game ball 10) is changed by colliding with the surface provided on the resin part 500. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10.

  Referring to FIGS. 7A and 7B, the discharge guiding portion 915 includes a guide passage 940 for guiding the game ball 10 from the ball raising switch (upper) 41 b toward the discharge lever 932 and a ball removal motor 931. And a discharge lever 932. A rectifier 916 is provided on the right side of the discharge guiding portion 915. The game ball 10 discharged from the ball raising switch (upper) 41 b reaches the guide passage 940. In the normal state shown in FIG. 7A, the game ball 10 is not discharged because it is blocked by the end surface of the discharge lever 932. However, in the discharge state shown in FIG. 7B, the discharge lever 932 operates to push out the game ball 10 to be discharged to the front. Then, the game ball 10 is guided to the guide unit 172 and discharged as a service ball. The discharge lever 932 operates when the ball removal motor 931 is rotated to the side where the game ball 10 is discharged by a predetermined pulse. For example, when the ball removal switch provided on the relay board is pressed once, the above operation is performed once, and one game ball 10 is discharged from the guide unit 172 as a service ball. For example, when the ball removal switch is pressed and held for a long time, a plurality of service balls can be discharged from the guide unit 172 by continuously performing the above-described operation, so that all the game balls 10 can be extracted to the outside of the gaming machine 1. In addition, it is preferable to perform the above operation | movement in conjunction with the conveyance operation of the conveying apparatus 190 using the ball raising switch (upper) 41b.

  Next, a configuration of a gaming island (also referred to as a gaming machine installation island) that supplies gaming balls to gaming machines and collects gaming balls from gaming machines after a game will be described. First, FIG. 8 is a front view showing a gaming island where a plurality of gaming machines are arranged. In the following description, the front side of FIG. 8 will be described as the front side of the game island, the back side as the rear side, and the left and right sides as the left and right sides.

  An upper tank 3A serving as a game medium storage unit that stores game balls, which are game media used for games of the game machine 2A, is located at an upper portion of the center of the game island in the longitudinal direction, that is, above each game machine 2A. The game balls stored in the upper tank 3A are disposed so as to incline downward from the lower surface of the upper tank 3A toward both longitudinal ends (left and right sides) of the game island. The left and right pair of supply rods 4A and 4A are allowed to flow.

  The game balls that have flowed into the replenishing rods 4A and 4A are replenished to the ball tanks 6A provided on the back surface of each gaming machine 2A through a plurality of tributary rods 5A provided at predetermined intervals in the downward direction. The game machine 2A is used for games (see FIG. 8).

  Further, at the downstream end of one of the left and right (right side in FIG. 8 in the present embodiment) supply ball 4A, a ball removal portion 30A for discharging the game ball in the supply bag 4A is provided. Two ball punching pipes 7A for guiding the game balls discharged from the ball punching part 30A into the lower tank 9A below are suspended from the ball punching part 30A. A detailed description of the replenishing rods 4A, 4A and the ball removal portion 30A will be described later.

  Each gaming machine 2A is placed on the upper surface of a repair plate installed in the longitudinal direction on each of the front and rear surfaces of the game island, and from the gaming machine 2A on the back side of each gaming machine 2A in the repair plate A plurality of out ball tanks 8A that receive the discharged out balls and discharge them into the lower tank 9A are provided corresponding to each gaming machine 2A.

  Below each gaming machine 2A, lower tanks 9A and 9A for storing game balls overflowing from the upper tank 3A and game balls transferred from other game islands are arranged at a substantially central position in the longitudinal direction of the game islands. Are provided on the left and right sides of the lifted polishing apparatus 11A. The left and right lower tanks 9A and 9A have different longitudinal width dimensions, but have the same internal structure, so the following description will be made on the lower tank 9A on the right side in FIG. 8, and the description on the lower tank 9A on the left side in FIG. Omitted. As shown in FIG. 9, the lower tank 9 </ b> A is formed in a horizontally long box shape whose upper surface is open. The inside of the lower tank 9A is partitioned in the longitudinal direction by a partition plate 22A extending in the front-rear width direction, and the region on the center side of the game island from the partition plate 22A has a game ball overflowing from the upper tank 3A and other A storage chamber 20A is provided for storing game balls transferred from the game island, and an area closer to the end of the game island than the partition plate 22A is discharged from the out-balls and ball removal pipes 7A discharged from each game machine 2A. It is set as a meeting room 21A in which game balls to be collected.

  The upper surface of the bottom plate 20Aa of the storage chamber 20A is an inclined surface that is inclined downward toward the longitudinal center of the game island, and the game balls stored in the storage chamber 20A are discharged from the lower tank formed on the side wall. It is guided in a natural flow toward the outlet 24A. A lower tank shutter device 28A including a lower tank shutter 26A capable of opening and closing the lower tank discharge port 24A and a lower tank motor for driving the lower tank shutter 26A is provided above the lower tank discharge port 24A. ing. The lower tank shutter 26A normally closes the lower tank discharge port 24A. When there is a request for opening, the lower tank shutter 26A retracts upward from the lower tank discharge port 24A and opens. A ball pressure reducing plate 25A for reducing the ball pressure is provided above the lower tank outlet 24A in the storage chamber 20A.

  A resin portion 500 is provided on the upper surface of the bottom plate 20Aa of the storage chamber 20A. When the game balls are stored in the storage chamber 20A, the upper surface of the bottom plate 20Aa of the storage chamber 20A becomes a surface on which a plurality of game balls can be stacked. By providing the resin portion 500 on the upper surface, the game can be performed with a force greater than its own weight. The sphere can be pressed against the resin portion 500. Further, as will be described later, the upper surface of the bottom plate 20Aa is a surface for changing the movement vector of the game ball dropped from the drop hole 18Aa provided in the falling plate 18A. Therefore, by providing the resin portion 500 on the surface, the resin portion 500 can be slightly scraped and attached to the surface of the game ball, thereby improving the lubricity of the game ball. In order to prevent the lubricity of the game ball from being excessively increased, a game machine that does not provide the resin portion 500 is provided in the upper surface of the bottom plate 20Aa of the storage chamber 20A through which the game ball overflowed from the upper tank 3A or the like passes. The resin part 500 may be provided for the path through which the game balls collected from 2A pass.

  In the upper part of the storage chamber 20A, a falling plate 18A on which a game ball guided through an overflow pipe 12A, an overflow hose 12Ab, and a sorting rod 12Ac, which will be described later, flows from the side wall on the center side in the longitudinal direction of the game island. It extends so as to incline downward toward the plate 22A. Further, on the front and rear sides of the flow down plate 18A, there are recovery rods 17A and 17A for collecting out balls discharged from each gaming machine 2A and guiding them to the collecting chamber 21A at a position slightly above the flow down plate 18A. It extends from the side wall on the center side in the longitudinal direction of the island so as to incline downward toward the partition plate 22A.

  The falling plate 18A is formed with a plurality of falling holes 18Aa for dropping the flowing game balls at predetermined intervals in the flowing direction, and between the falling plate 18A and the recovery rods 17A, 17A, Is formed in the storage chamber 20A from the drop hole 18Aa or from both side ends in the flow-down direction, and is stored substantially uniformly in the longitudinal direction. On the other hand, all the game balls flowing down the collection baskets 17A and 17A are guided to the collecting chamber 21A without falling in the middle of the flow.

  The game balls guided to the collective chamber 21A flow out into the collective ball flow down passage 23A that is inclined in the longitudinal direction on the lower surface of the bottom plate 20Aa of the storage chamber 20A. After flowing down toward the center side of the steel, it is guided to the lifting and polishing apparatus 11A through a connecting rod 10A that connects the lifting and polishing apparatus 11A and the lower tank 9A. Further, the game balls discharged from the lower tank discharge port 24A are discharged to the connecting rod 10A, joined with the game balls flowing down the collective ball flow down passage 23A, and guided to the lifting and polishing apparatus 11A.

  A resin portion 500 is also provided on the bottom surface of the collective ball flow passage 23A. When a game ball passes through the collective ball flow down passage 23A, the bottom surface of the collective ball flow down passage 23A becomes a surface on which a plurality of game balls can be stacked. The sphere can be pressed against the resin portion 500. In addition, a part of the bottom surface of the collective ball flow down passage 23A becomes a surface for changing the movement vector of the game ball guided to the collective chamber 21A. Therefore, by providing the resin portion 500 on the surface, the resin portion 500 can be slightly scraped and attached to the surface of the game ball, thereby improving the lubricity of the game ball. In order to avoid excessively improving the lubricity of the game balls, the game machine 2A is provided without providing the resin portion 500 for the path through which the game balls overflowed from the upper tank 3A or the like pass through the bottom surface of the collecting ball flow-down passage 23A. The resin part 500 may be provided for the path through which the game balls collected from the vehicle pass.

  Although not shown in detail in detail, the lifting and polishing apparatus 11A uses a lifting motor (not shown) to pull a belt stretched over pulleys provided on the upper and lower sides of a box-shaped main body facing in the vertical direction. By rotating by rotating, the game ball guided by the connecting rod 10A and flowing in from the inlet provided at the lower portion of the lifting and polishing apparatus 11A is lifted by pressing it against the lifting groove with a belt, This is a conventionally known device that lifts a game ball while polishing it by laying a polishing cloth between the lift groove and the game ball. Further, the lifted game balls are discharged from a lift ball discharge port (not shown) formed in the upper part of the box.

  As shown in FIG. 10, the upper tank 3A is fixed to the upper part of the game island, and is formed in a horizontally long box shape whose left-right width dimension is longer than the front-rear width dimension, and is arranged above the upper tank 3A. The game balls discharged from the lifting ball outlet are stored. Its capacity is larger than that of the lower tanks 9A and 9A, and has a size capable of storing most of the game balls (about 110,000 shots in this embodiment) to be supplied to each game machine 2A installed on the game island. Thus, it is possible to store a larger amount of game balls than the total storage amount when both the storage chambers 20A of the lower tanks 9A and 9A are full.

  Specifically, the upper tank 3A is formed in a box shape by a front plate 50Aa, a rear plate 50Ab, a pair of left and right side plates 50Ac, 50Ac, a bottom plate 50Ad, and an upper plate (not shown). In 50Aa, a concave groove 51A for accommodating and disposing the upper part of the lift polishing apparatus 11A is provided from the upper end to the lower end. An outlet 52A to which a connection member 40Aa for connecting a transfer rod as a game medium transfer rod is connected is formed at the upper part of each of the left and right side plates 50Ac, 50Ac, and at the lower part of each game is a game outlet An inflow port 53A to which a connection member 41Aa for connecting a receiving bowl as a medium receiving bowl is connected is formed.

  The bottom plate 50Ad is formed in a substantially concave shape in plan view, and a storage ball outlet 54A is formed at a substantially central position thereof, that is, on the rear surface side of the concave groove 51A, and the upper surface of the bottom plate 50Ad is a central storage. Inclined downward toward the ball outlet 54A. The upper surface of the supply ball outlet 54A is connected to the upper end of the supply rod connection pipe 65A to which the upstream end of the supply rod 4A, 4A described above is connected, and the game ball stored on the bottom plate 50Ad, That is, all the game balls stored in the storage area of the upper tank 3A flow out from the storage ball outlet 54A to the supply rods 4A and 4A via the supply rod connection pipe 65A. The replenishing rod connecting pipe 65A is disposed so that the front surface thereof is substantially flush with the rear surface of the concave groove 51A.

  At the upper end of the concave groove 51A in the front plate 50Aa, a receiving port is formed in which the lifting ball discharge port 11Aa of the lifting polishing apparatus 11A is disposed so as to face the game ball discharged from the lifting ball discharge port 11Aa. It is designed to be received in the upper tank 3A.

  At the lower position of the receiving port in the upper part of the upper tank 3A, the first guiding plate 56A that receives the game balls discharged from the lifting ball discharge port 11Aa and falling from below and guides them toward the left and right outlets 52A, 52A. Is arranged. The first guide plate 56A is disposed between the concave groove 51A and the rear plate 50Ab, and is made of a metal plate bent in a mountain fold centered on the center in the left-right direction, and is inclined downward from the center toward the left-right side. Since it has an inclined surface, the game balls that have been discharged from the lifting ball discharge port 11a and dropped onto the top of the first guide plate 56A are distributed substantially equally to the left and right sides. In addition, a rear notch 56Aa is formed at the center of the rear side of the first guide plate 56A, and a front notch 56Ab is formed at the center of the front side, so that the game on the first guide plate 56A is performed. A part of the sphere falls from the rear notch 56Aa and the front notch 56Ab.

  On the left and right sides of the first guide plate 56A, a pair of left and right second guide plates 57A and 57A that are inclined downward from the left and right side portions of the first guide plate 56A toward the side plate 50Ac are disposed. Further, below the second guide plates 57A and 57A, a pair of left and right third guide plates 58A and 58A inclined downward from the center position in the left and right direction toward the side plate 50Ac are second guide plates 57A and 57A. It is arrange | positioned so that the downward direction may be covered. A plurality of drop holes 57Aa are formed in the second guide plates 57A and 57A. Note that the resin portion 500 is not provided on the upper surfaces of the second guide plates 57A and 57A on which the collected game balls hit well so as not to increase the lubricity of the game balls too much.

  A pair of front and rear cutouts 58Aa and 58Aa are formed in the front and rear of the left and right end sides of the third guide plates 58A and 58A, respectively, and a gap is formed between the inner surfaces of the side plates 50Ac. The tip of the central piece 58Ab between the pair of front and rear cutouts 58Aa and 58Aa is located at a substantially central position in the vertical direction in the outlet 52A as shown in FIG. 10B. It is arranged to protrude slightly from the outside. Therefore, the game balls flowing down on the third guide plates 58A and 58A can be directly guided into the outlet 52A, and the storage position of the game balls stored in the upper tank 3A is raised to lower the lower edge of the outlet 52A. Is exceeded, the third guide plates 58A, 58A flow out from below the central piece 58Ab at the outlet 52A without being blocked by the third guide plates 58A, 58A.

  Further, below the first guide plate 56A, a fourth guide plate 59A that receives the game ball dropped from the rear notch 56Aa and guides it to the left and right third guide plates 58A, 58A is disposed. The fourth guide plate 59A is in the form of a strip having a front-rear width smaller than the front-rear width of the first guide plate 56A, and is made of a metal plate bent in a mountain fold around the center in the left-right direction. By having an inclined surface that is inclined downward toward the left and right, the game balls dropped from the rear notch 56Aa can be distributed substantially equally to the left and right sides.

  Between the first guide plate 56A and the storage ball outlet 54A, an overflow pipe 12A is disposed in the vertical direction. The upper end of the overflow pipe 12A is opened to form an overflow port 12Aa through which the overflowing game ball can flow out. The overflow port 12Aa has an opening smaller than the front cutout portion 56Ab of the first guide plate 56A (see FIG. 10A), and is disposed in close proximity to the front cutout portion 56Ab.

  An overflow hose 12Ab is connected to the lower end of the overflow pipe 12A extending below the bottom plate 50Ad, and the overflow hose 12Ab is suspended along the lift polishing apparatus 11A (see FIG. 8). . As shown in FIG. 9 (b), the lower end of the overflow hose 12Ab is arranged at the upper position of the top of the sorting rod 12Ac bent and formed into a mountain fold, and the game that has flowed out from the lower end opening of the overflow hose 12Ab The balls are distributed to the left and right lower tanks 9A, 9A.

  In addition, on the left and right side surfaces of the bent portion of the overflow pipe 12A, a confluence port to which one end of the inflow sphere guide pipes 60A and 60A connected to the inflow ports 53A and 53A is connected is more than the inflow ports 53A and 53A. It is formed at a slightly lower position. Thereby, the game ball flowing in from the inflow ports 53A and 53A naturally flows down in the inflow ball guiding tubes 60A and 60A facing in the left-right direction, and is not stored in the upper tank 3A, but is bent in the bent portion of the overflow tube 12A. Are joined into the overflow pipe 12A from the junction formed in the left and right side surfaces.

  As described above, the game ball overflowing from the overflow port 12Aa and the game ball flowing in from the inflow ports 53A and 53A are guided to the rear side of the upper tank 3A by the overflow pipe 12A and then fall downward, and overflow hose After being guided to the flow-down plate 18A of the lower tanks 9A and 9A by 12Ab and the distribution rod 12Ac, they are stored in the storage chamber 20A.

  In addition, since the upper part of the overflow pipe 12A is disposed immediately above the storage ball outlet 54A, it is prevented that the ball pressure of the storage ball is applied to the storage ball outlet 54A. The air flows smoothly into the stored ball outlet 54A from the gap formed between the lower surface of the bent portion of the overflow pipe 12A and the stored ball outlet 54A.

  Further, since the overflow port 12Aa is disposed at a height above the upper edge of the outlets 52A, 52A, the storage position of the game balls stored in the upper tank 3A is played from the outlets 52A, 52A. There is no overflow at the storage position where the ball does not flow out naturally. That is, the game ball can be stored in the upper tank 3A to the storage position where the game ball can naturally flow out from the outlets 52A, 52A.

  As described above, the game ball discharged from the lifting ball discharge port 11a falls over the front notch portion 56Ab to the center position in the left-right direction of the first guide plate 56A on the rear surface side, and part of the game ball is left and right The flow is distributed to the side and flows down on the inclined surface, and a part thereof falls on the fourth guide plates 59A and 59A from the rear notch 56Aa and is guided to the left and right third guide plates 58A and 58A. There is almost no possibility of falling directly from the notch 56Ab and flowing into the overflow pipe 12A or being stored in the upper tank 3A.

  The game balls guided left and right by the first guide plate 56A fall on the second guide plates 57A and 57A and flow down to the left and right sides. A part of the game balls dropped on the second guide plates 57A and 57A are directly dropped and stored from the drop holes 57Aa, but most of the game balls are dropped on the left and right sides of the second guide plates 57A and 57A or dropped. After dropping onto the third guide plates 58A and 58A from the hole 57Aa, flowing down on the third guide plates 58A and 58A and being guided to the outlets 52A and 52A, the central piece 58Ab flows out of the outlets 52A and 52A. . In other words, the first to fourth guide plates 56A, 57A, 58A, 59A give most of the game balls discharged from the lifting ball discharge port 11Aa to the outlets 52A, 52A in preference to the storage in the upper tank 3A. The guiding means of the present invention for guiding is configured.

  When there are few game balls in the transfer bowl and the outlets 52A and 52A are not blocked, the game balls guided to the outlets 52A and 52A by the third guide plates 58A and 58A are the outlets 52A and 52A. Spilled from. On the other hand, when the game balls are filled with the game balls and the outlets 52A and 52A are blocked, the game balls guided to the central piece 58Ab of the third guide plates 58A and 58A are distributed back and forth. The pair of notches 58Aa and 58Aa (see FIG. 10A) are dropped and stored in the upper tank 3A.

  Further, when the storage position of the game ball stored in the upper tank 3A rises and reaches the lower end edge of the outflow port 52A, it flows out from the lower position of the central piece 58Ab of the third guide plate 58A in the outflow port 52A. To go. The notches 58Aa and 58Aa are arranged close to the inner surface of the side plate 50Ac in which the outflow port 52A is formed, so that they are closer to the end than the central portion of the storage region where the overflow port 12Aa is arranged. The game balls are stored preferentially, and the storage position easily reaches the outlet 52A.

  Further, when the storage position of the game ball stored in the upper tank 3A rises and reaches the upper position of the first guide plate 56A, the rear cutout portion 56Aa is also in a closed state. The game ball discharged from 11Aa falls from the front notch 56Ab and flows out into the overflow port 12Aa without flowing down on the first guide plate 56A (overflow).

  On the inner surface of the rear plate 50Ab, it is detected that the storage position of the game balls stored in the upper tank 3A has reached the reference position, which is the first position where the game balls can flow out from the outlets 52A, 52A. The reference sensor 70A as the first position detecting means and the storage position of the game ball stored in the upper tank 3A are the reference position and the second position below the opening lower edge of the outlets 52A, 52A. A lower limit sensor 71A as second position detecting means for detecting that a certain lower limit position has been reached is provided above and below.

  Specifically, as shown in FIG. 10 (b), the reference sensor 70A is disposed at a height slightly above the overflow port 12Aa, and the lower limit sensor 71A receives a game ball from the outlets 52A and 52A. The reference position where it can flow out, that is, below the lower opening edge of the outlets 52A and 52A, is located slightly below the intermediate position between the bottom plate 50Ad and the reference position.

  That is, the reference sensor 70A is a sensor for detecting that the storage position of the game ball stored in the upper tank 3A has reached the overflow port 12Aa, that is, has reached the upper limit storage position of the upper tank 3A. Yes, the lower limit sensor 71A indicates that the storage position of the game balls stored in the upper tank 3A has become half or less. Specifically, the game balls cannot flow out from the outlets 52A, 52A, and It is a sensor for detecting that it is a lower limit storage position where there is a risk that supply to the gaming machine 2A will be interrupted if below.

  In the present embodiment, the reference sensor 70A is disposed slightly above the position where the overflow port 12Aa is disposed. However, the reference sensor 70A is located at a height higher than the outflow position above the lower opening edge of the outlets 52A, 52A. If so, it may be disposed below the position where the overflow port 12Aa is disposed, or may be disposed above the position where the overflow port 12Aa is disposed. The lower limit sensor 71A may be disposed at a height position corresponding to the quantity, model, and capacity of the upper tank 3A of the gaming machine 2A installed on the game island, and the height position described in the present embodiment. It is not limited to.

  Since the upper tank 3A has a structure capable of storing a large amount of game balls, there are many surfaces on which a plurality of game balls can be stacked. For example, the inner surface of the bottom plate 50Ad and the upper surfaces of the inflow ball guiding tubes 60A, 60A are surfaces on which a plurality of game balls can be stacked, and the resin portion 500 can be provided on the surfaces. When the game ball is stored in the upper tank 3A, the game ball can be pressed against the resin portion 500 provided on the surface with a force greater than its own weight. Further, the game balls stored on the bottom plate 50Ad flow from the storage ball outlet 54A to the supply rods 4A and 4A via the supply rod connection pipe 65A, that is, the game balls flowing out to the supply rods 4A and 4A. A resin part 500 is provided at a position where the movement vector is changed. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball, thereby improving the lubricity of the game ball.

  Next, the replenishing rods 4A and 4A that supply the game balls stored in the upper tank 3A to each gaming machine 2A will be described. 11A is a plan view of the replenishing rods 4A and 4A, and FIG. 11B is a longitudinal sectional view of the replenishing rods 4A and 4A. As shown in FIG. 11 (b), the replenishing rods 4A, 4A have a substantially upward U-shaped longitudinal section, and the side plates 4Aa, 4Aa before and after the replenishing game balls 2A are replenished to each gaming machine 2A. A plurality of replenishing ports 4Ab are formed at predetermined intervals in the flow-down direction. On the outer surface of these replenishing ports 4Ab, an upper part of a branch basin 5A hanging downward is attached, and the game balls that flow into each replenishing port 4Ab flow down the tributary basin 5A and each gaming machine 2A. Is supplied to a ball tank 6A provided on the back surface of the ball.

  As shown in FIG. 11B, the bottom plate 4Ac of the replenishing rod 4A is bent and formed into a mountain fold slightly inclined downward from the center in the width direction toward both ends, thereby flowing down on the bottom plate 4Ac. A game ball to be played is guided to a supply port 4Ab formed in the front and rear side plates 4Aa and 4Aa. That is, the inclined surface of the bottom plate 4Ac constitutes a replenishment portion guiding means of the present invention that guides the game ball flowing down on the replenishment rods 4A and 4A toward the plurality of replenishment ports 4Ab.

  As shown in FIG. 11 (a), the ball removal portion 30A has a downstream end portion on the right side of the supply rod 4A in FIG. 8, more specifically, the most downstream side of the plurality of supply ports 4Ab provided in the supply rod 4A. Is provided on the downstream side of the supply port 4Ab provided in the game, so that the game balls in the supply basket 4A can be discharged as needed. Specifically, the ball removal unit 30A includes a ball removal shutter 32A that can open and close the flow path of the ball removal unit 30A and a ball removal shutter device that has a ball removal motor for driving the ball removal shutter 32A (see FIG. Not shown).

  When the ball removal shutter 32A is retracted from the flow path and the flow path is opened, the game ball in the replenishing basket 4A flows down and flows into the upper end opening of the ball removal pipe 7A provided on the downstream side. It flows down in the ball extraction tube 7A and is guided into the collecting chamber 21A. Note that the diameter of the upper end opening of the ball punching tube 7A is smaller than the front-rear width dimension of the replenishing rod 4A, and the game balls in the replenishing rod 4A all flow down when the flow path of the ball removing portion 30A is opened. Thus, the discharge does not hinder the supply of game balls to the gaming machine 2A.

  Further, when the ball removal portion 30A is provided on the downstream side of the supply port 4Ab provided at the most downstream position of the supply rods 4A and 4A in this way, the balls flowing down on the supply rods 4A and 4A are more replenished. As shown in FIG. 11, the upper surface of the bottom plate 4Ac on the upstream side of each supply port 4Ab provided on the side in the flow direction is directed toward the supply port 4Ab. A guide piece 80A for guiding the game ball may be erected. Thereby, even when the game ball is discharged from the ball removal portion 30A, the game ball flowing down is preferentially supplied to the supply port 4Ab, and the ball pressure applied to the ball removal shutter 32A is reduced. .

  When the game balls flow down to the supply baskets 4A, 4A, the bottom plate 4Ac of the supply baskets 4A, 4A becomes a surface on which a plurality of game balls 10 can be stacked, and by providing the resin portion 500 on the bottom surface, a force more than its own weight is provided. The game ball 10 can be pressed against the resin portion 500. In addition, the movement vector of the game ball flowing down the supply baskets 4A and 4A is changed by the guide piece 80A. Therefore, the resin part 500 is provided on the surface of the guide piece 80A on which the game ball 10 flowing down the replenishing rods 4A and 4A collides. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10.

  As described above, the replenishment rod 4A, the branch flow rod 5A, the ball discharge tube 7A, the overflow tube 12A, the overflow hose 12Ab, the sorting rod 12Ac, the recovery rod 17A, the falling plate 18A, and the collective ball flow passage 23A arranged in the game island. The connecting rod 10A, the upper tank 3A, the lower tank 9A, the gaming machine 2A, the lifting and polishing apparatus 11A, and the like constitute a circulation path for circulating the game ball in the game island.

  In addition, one of the multiple amusement islands installed in the amusement store and another island that is adjacent to the front and back of the one island (here I saw the island from the left and right sides) In this case, game islands arranged adjacent to the left and right sides of the island are called left and right islands, respectively, and are installed between upper tanks 3A and 3A for transferring game balls from the island to other islands. A transport rod as a game medium transport rod and a receiving rod as a game medium receiving rod for a single island to receive game balls from other islands are provided.

  Next, the path of the game balls that flow into the replenishment ports 4Ab, flow down the tributaries 5A, and are replenished to the ball tank 6A provided on the back of each game machine 2A leads to the upper plate of the game machine. explain. FIG. 12 is a perspective view of the mechanism plate of the gaming machine as viewed from an oblique direction on the gaming machine front side. In the mechanism plate of the gaming machine shown in FIG. 12, the gaming balls replenished to the ball tank 6A flow down to the upper plate or the like of the gaming machine through a path indicated by an arrow. And the resin part 500 is provided in the position which changes the movement vector of the game ball 10 which flows down the said path | route. Specifically, the resin portion 500 is provided at a position where the game ball flowing down from the ball tank 6A flows leftward along the path, falls along the left side surface of the mechanism plate, and changes direction to the right. Since the dropped game ball 10 collides with the resin part 500, the resin part 500 is slightly scraped off and attached to the surface of the game ball 10, thereby improving the lubricity of the game ball 10.

  However, a removal unit 501 for removing the scraped resin is provided on the right side of the resin part 500 in order to prevent a problem that the scraped resin adheres too much to the surface of the game ball 10. The removal unit 501 shakes off the resin that has adhered in a shape (for example, a saw blade shape) in which convex portions and concave portions are alternately provided from the game ball 10, or the resin that has adhered too much with rubber or the like as a game ball It is the structure which adsorb | sucks and drops from 10. The removing unit 501 is configured to prevent resin or the like from adhering to the surface of the game ball 10 more than necessary, and may be provided at other positions on the game machine and the game island. For example, the removal unit 501 may be provided at a position in the vicinity where the resin unit 500 is provided, a position where a plurality of game balls 10 can be stacked, or a position where the movement vector of the game ball 10 is changed.

  Further, in the mechanism plate of the gaming machine shown in FIG. 12, the resin portion 500 is also provided in the portion in front of the central portion such as the upper plate. Since the game ball that has flowed down the path on the surface provided with the resin portion 500 changes the direction in the direction of the upper dish, the resin portion 500 is slightly scraped off and attached to the surface of the game ball 10. Lubricity can be improved. A resin portion 500 is also provided on the bottom surface of the ball tank 6A. The bottom surface of the ball tank 6A is a surface on which a plurality of game balls 10 can be stacked. By providing the resin portion 500 on the bottom surface, the game ball 10 can be pressed against the resin portion 500 with a force greater than its own weight. Therefore, the resin portion 500 can be slightly scraped and attached to the surface of the game ball 10 to improve the lubricity of the game ball 10.

  As the base body of the mechanism plate, an ABS resin plate containing 6% by weight of stainless fiber is used. Therefore, the base body of the mechanism plate has conductivity. On the side of the mechanism plate, a stainless steel fitting 209 extending in the height direction from the vicinity of the position of the ball tank 6A to the vicinity of the position of the connection port to the upper plate is installed. Since the base body of the mechanism plate has conductivity, the base body of the mechanism plate and the metal fitting 209 are electrically connected to each other by installing the metal fitting 209 on the base body of the mechanism plate. .

  Generally, since the card unit is grounded via a grounding wire, if a grounding point on the gaming machine side is connected to an FG (frame ground) terminal of the card unit, the grounding point on the gaming machine side is easily grounded. be able to. In the present embodiment, a connector that is electrically connected to the metal fitting 209 is provided on the dispensing control board. A wiring 214 extending from the connector is connected to the metal fitting 209. In the payout control board, the wire electrically connected to the metal fitting 209 is connected to the connector. The wire electrically connected to the metal fitting 209 via the connector and the cable is connected to the FG terminal of the card unit. Therefore, the conductive ball tank 6A and the metal plate 209 of the mechanism plate are grounded via the card unit.

  In this embodiment, the sphere tank 6A is formed of an ABS resin containing 8% by weight of carbon. Therefore, the ball tank 6A has conductivity. Further, a metal ground plate (metal plate) 218 is fitted into a part of the ball tank 6A on the front side of the gaming machine. The ground plate 218 can contact a game ball stored in the ball tank 6A. Therefore, the potential of the game ball becomes the same as the potential of the ground plate 218 when stored in the ball tank 6A. Further, since the portion other than the ground plate 218 in the ball tank 6A is made of a synthetic resin containing carbon and has conductivity, the potential of the game ball becomes the same as the potential of the entire ball tank 6A. Further, in the game store, the game balls are supplied to the ball tank 6A of the gaming machine after passing through the supply path provided on the game island, so that the game balls are already charged before being supplied to the ball tank 6A. There are many. However, since the ball tank 6A is made of conductive synthetic resin containing carbon and is grounded, the charge of the game ball escapes to the ground side via the ball tank 6A and the charge of the game machine is eliminated. . By eliminating the charging of the game ball, the shaved resin can be uniformly attached and the lubricity of the game ball can be improved uniformly.

  As shown in FIG. 12, the wiring 211 is connected to the metal plate 209 of the mechanism plate by the connecting portion 213. Since the metal fitting 209 is grounded via the card unit, the potential of the ball tank 103 is also at the ground level.
