Description

  The present invention relates to a gaming machine.

  Some gaming machines such as pachinko machines are provided with a gaming board having a gaming area formed on the front surface. When a game ball launched based on a player's launch operation enters a winning part (wins) in a game area, the winning is detected by a detection sensor. The detected information is transmitted to the control device, and the control device executes processing for giving a privilege such as paying out a game ball to the player based on this information (see, for example, Patent Document 1).

  In a gaming machine of a type in which a privilege is given in response to a winning at such a winning part, whether or not the game can be advantageously advanced according to a winning occurrence rate (winning frequency) to the winning part Can occur. For this reason, a game is played in the expectation that many entrances to the entrance part will occur.

JP 2003-190511 A

  In recent years, various fraudulent acts on gaming machines aimed to enjoy many benefits have been reported. For example, there is a fraudulent act (so-called thread hanging goto) in which a game ball to which a tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area and the game ball is manipulated by the thread-like member. According to this fraudulent act, for example, by guiding the thread-like member by hand, the subsequent game ball is guided to the entrance part, or the thread-like member is placed against the detection area of the detection sensor provided in the entrance part. Reciprocating a fixed game ball may cause a misunderstanding as if a large number of game balls have been won, and a privilege may be obtained illegally. Such fraudulent acts are less conspicuous than fraudulent acts such as fraudulent fraud, and it is difficult for the hall manager to find the fraudulent acts visually.

  However, at present, effective measures against such illegal acts are not actually taken, and there is still room for improvement in the crime prevention function of the gaming machine in order to suppress such illegal acts.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a gaming machine capable of suitably improving the crime prevention function of the gaming machine.

  Hereinafter, means for solving the above problems will be described.

In the glass unit 22, the gap between the rear glass panel 23 and 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 the same in the game area PE. It is arranged so that it is not lined up back and forth at a point. Thereby, the ball blockage in the game area PE is suppressed. Note that the game board 80 (specifically, the plate body 80a) is not limited to wood, and may be made of synthetic resin. Further, it is a coating that forms various patterns in place of the sheet material. Etc. can also be adopted.

  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 detection sensors (not shown) provided corresponding to the respective winning portions, and the detection results thereof. Based on the above, a predetermined number of award balls (payout of game balls) and the like are given to the player. In addition, an out port 89 is provided at the lowermost part of the game board 80, and game balls that have not entered the various entrances or the like are discharged from the game area PE through the out port 89. In the following description, in order to clearly distinguish the game ball from entering the out port 89, the game ball entering the general winning port 81, the variable winning device 82, and the operation ports 83a and 83b is also referred to as "winning". Express.

  The game board 80 is provided with a large number of nails for distributing and adjusting the flow path of the game balls as appropriate, and various members (functions) such as a windmill. The flow path of the game ball is differentiated by various configurations such as nails and windmills, and is adjusted so that the winning to the above-described general winning opening 81 and the like occurs with an appropriate probability.

  The variable display unit 85 is disposed in the center of the game board 80, and operating ports 83a, 83b and the like are disposed around the variable display unit 85. The operation ports 83a and 83b are composed of an upper operation port 83a disposed below the variable display unit 85 and a lower operation port 83b disposed directly below the upper operation port 83a. The (lottery opportunity entrance ball portion) 83b is provided with an electric accessory 91 as an open / close type entrance assist device (entrance assisting means) or an opening / closing member (opening / closing means). The electric accessory 91 includes a pair of left and right movable pieces and a solenoid-type drive unit that drives the movable pieces, and an open state (auxiliary state) in which a ball can be easily or easily entered into the lower working port 83b. Then, it is possible to switch to a closed state (non-auxiliary state) in which the same ball cannot be or is difficult.

  The through gate 84 is arranged on the upstream side of the lower operating port 83b (specifically, on the side of the variable display unit 85), and the winning is made by lottery triggered by the passage of the game ball through the through gate 84. In this case, the electric accessory 91 is switched from the closed state to the open state for a predetermined time.

  When a ball enters the upper operation port 83a, three game balls are paid out. When a ball enters the lower operation port 83b, four game balls are paid out. However, the number of game balls to be paid out is not limited to the above. However, in order to increase the advantage of the lower working port 83b with respect to the upper working port 83a, it is preferable to set the number of payouts related to the lower working port 83b larger than the number of payouts related to the upper working port 83a.

  The variable winning device (special winning device or special winning means) 82 has a large winning port 82a leading to the back side of the game board 80, and an open / close member (open / close) for opening and closing the special winning port 82a. As a means, an open / close door 82b is provided. The open / close door 82b can be switched between an open state (assist state) where a game ball can be entered or facilitated and a closed state (non-assistant state) where the entrance ball is impossible or difficult. The opening / closing door 82b is connected to a variable prize driving unit 82c (specifically, a solenoid) provided on the back side of the game board 80, and the opening / closing door 82b is maintained in a closed state in a normal state. When the lottery wins the transition to the opening / closing execution mode (opening / closing execution state), it is switched to the open state (when winning the special game state that is more advantageous to the player than the normal game state) It has become.

  Here, the opening / closing execution mode is a mode to be shifted to when a big win is won. As an opening mode of the variable winning device 82 in the opening / closing execution mode, for example, a predetermined time (for example, 30 sec) or a predetermined number (for example, 10) of winnings is set as one round, and a plurality of rounds (for example, 16 rounds) is set as an upper limit. Some are set so that the opening and closing of the door 82b is repeated.

  Next, the variable display unit 85 will be described. The variable display unit 85 includes a symbol display device 94 that variably displays symbols (variation display) using a winning at 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, and the display content is controlled by a display control device described later. On the symbol display device 94, for example, symbols are displayed side by side in the top, middle, and bottom, and these symbols are variably displayed as they are scrolled in the horizontal direction. When a big win is won, a predetermined combination of symbols is stopped and displayed on a preset active line, and the mode is shifted to the opening / closing execution mode (special game state or big win). The symbol display device 94 is not necessarily a liquid crystal display device, and may be a dot matrix or 7-segment display device.

  The variable display unit 85 includes a center frame 95 disposed so as to surround the symbol display device 94. The center frame 95 is fixed to the game board 80 (plate body 80a) from the front side thereof, and in such a fixed state, the center frame 95 is raised from the front side of the game board 80. And the glass unit 22 are configured such that the gap dimension is smaller than the diameter dimension of the game ball. This prevents the game ball flowing down the game area PE from colliding with the symbol display device 94, and the flow path of the game ball flowing down the game area PE is on the right side of the variable display unit 85 (specifically, the center frame 95). The route is divided roughly into the route that detours from and the route that detours from the left side.

  At the lower part of the center frame 95, a first holding ramp portion 98a and a second holding ramp portion 98b are provided. The first hold lamp portion 98a on the left side corresponds to the upper operation port 83a, and the number of times that the game ball has passed through the upper operation port 83a is held up to a maximum of four times. It is displayed. The second holding lamp portion 98b on the right side corresponds to the lower operating port 83b, and the number of times that the game ball has passed through the lower operating port 83b is held up to four times. Is displayed.

  The operation ports 83a and 83b are arranged at positions close to the variable display unit 85. Since it is possible to shift to the special game state by using a winning at the operation ports 83a and 83b as a trigger, the player pays attention to whether or not the operation ports 83a and 83b are won, and grasps whether or not to shift to the special game state. Therefore, it is considered that the symbol display device 94 is noted. Providing the operation ports 83a and 83b closer to the variable display unit 85 is a device for concentrating a portion that the player wants to focus on around the variable display unit 85.

  A game area partition member 99 that partitions the game area PE together with the guide rail 100 described later is disposed at the right end of the game board 80 (the rotation tip of the game board 80 described later). The game area partition member 99 is provided with a stopper member with which a game ball flying along the main display unit 87 and the guide rail 100 collides. The stopper member is a buffer member arranged near the tip of the guide rail 100, and the game ball that collides with the stopper member flows down the game area PE after the momentum is weakened. That is, the stopper member is provided with a depressing function that weakens the momentum of the game ball that has collided.

  Here, the main display unit 87 will be described supplementarily. The main display unit 87 is embedded in the game area partition member 99, and a part of the main display unit 87 is arranged to face the glass unit 22. A main display portion D on which a predetermined pattern or the like is displayed is provided in the facing portion. The main display unit 87 is electrically connected to a main controller described later, and the display content of the main display unit D is controlled by the main controller.

  The main display portion D has a lower working port display unit for displaying a lottery result based on a winning to the upper working port 83a, and a right working port for displaying a lottery result made based on a winning to the lower working port 83b. Display unit. In the lower working port display section, the display of the variation of the pattern is performed with the winning of the upper working port 83a as a trigger, and as a result of stopping the variation display, the internal lottery performed based on the winning of the upper working port 83a is performed. The result is specified. When the result of the internal lottery based on the winning to the upper working port 83a is the winning result corresponding to the shift to the opening / closing execution mode, the variable display is stopped on the lower working port display section, and the stop result is predetermined. After the pattern is displayed, the mode is shifted to the opening / closing execution mode.

  The display portion for the right working port displays a variation of the picture triggered by a winning at the lower working port 83b, and as a result of stopping the variation display, the internal lottery performed based on the winning at the lower working port 83b is performed. The result is specified. When the result of the internal lottery based on the winning to the lower working port 83b is a winning result corresponding to the jackpot, the change display is stopped on the display unit for the right working port, and a predetermined pattern is displayed as the stop result. After that, the mode is shifted to the opening / closing execution mode according to the result.

  Here, on the basis of winning in any one of the operation ports 83a and 83b, the display of variation is started at the corresponding operation port display unit, until a predetermined stop result is displayed and the variation display is stopped. It corresponds to one time. However, the number of game times is not limited to the above-mentioned contents. For example, a single display area is provided, and even if a winning to any of the operation ports 83a and 83b occurs, the single game area In the configuration in which the variable display is performed in the display area, the variable display is started in the single display area, and the above-mentioned variable display is stopped once in a state where a predetermined stop result is displayed. It is also possible.

  Further, the main display unit D of the main display unit 87 is provided with a through-gate display unit for displaying a lottery result based on winning through the through-gate 84 in addition to the two display units. In the through gate display unit, the display of the variation of the picture is performed with the winning of the through gate 84 as a trigger, and the result of the internal lottery performed based on the winning of the through gate 84 is clearly shown as the result of stopping the variation display. Is done. If the result of the internal lottery based on the winning to the through gate 84 is a winning result corresponding to the transition to the open state, a predetermined stop result is displayed on the through gate display unit, and the change display is displayed. After being stopped, the state shifts to the electric power open state. In the electric combination open state, the electric combination 91 provided in the lower operation port 83b is opened in a predetermined manner.

  Furthermore, in the present embodiment, a configuration is adopted in which the number of times that the game ball has passed through the through gate 84 is retained up to 4 times, but the number of suspension is displayed on the main display portion D of the main display unit 87. A display unit for the number of hold to be provided is provided.

  About the main display part D explained in full detail above, while being visible from the front of the pachinko machine 10 through the glass unit 22 of the front door frame 14, it is avoided that a game ball moves in front of these various display parts. Therefore, the visibility is guaranteed.

  The configuration of the inner frame 13 will be described again with reference to FIG. 5. A game ball is launched to the game area PE below the game board 80 in the inner frame base body 50 based on the operation of the game ball launch handle 41. A game ball launching mechanism 110 is provided.

(Game Ball Launching Mechanism 110)
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 an inner frame base body 50 (for example, a lateral frame member 57 described later). ) To be integrated with the inner frame base body 50.

  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. The firing rail 112 is formed with a groove portion having a substantially V-shaped cross section, and the front and rear positions of the game ball are defined by fitting the game ball into the groove portion.

  A ball stopper 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 arranged at a position further downstream than the ball stopper.

  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 99 fixed to the game board 80 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 that are arranged so as to face each other with a gap larger than the diameter of the game ball, and a single guide passage 103 is formed by both the rails 101 and 102. Has been. 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. That is, when a game ball is launched so as to be delivered to the game area PE, the area along the outer rail 102 in the guide passage 103 substantially constitutes a pass area (passage path) through which the game ball passes. However, the area along the inner rail 101 is an area through which the game ball does not pass.

  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 is disposed below the gap formed in this way. The foul ball path is formed integrally with the path forming unit 45 of the front door frame 14. If the game balls launched from the game ball launching mechanism 110 do not reach the game area PE and return to the inside of the guide passage 103 as foul balls, the foul balls enter the foul ball passage through the gap. Become. The foul ball path leads to the front door side lower dish path, and the game balls that have entered the foul ball path are discharged to the lower dish 34 shown in FIG. This suppresses interference between the foul ball and the next game ball to be launched.

  A through-hole penetrating the inner frame base body 50 in the front-rear direction is formed on the left side of the firing rail 112 in the inner frame base body 50 (specifically, the side supporting the front door frame 14). A passage forming member 121 is disposed on the side. The passage forming member 121 is screwed to the inner frame base body 50 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. In addition, a receiving portion of a passage forming unit attached to the front door frame 14 enters below the passage forming member 121, and a front door side upper plate passage is disposed below the main body side upper plate passage 122, A front door side upper dish passage is disposed below the main body side lower dish passage 123.

  An opening / closing member 124 for opening and closing the main body side upper dish path 122 and the main body side lower dish path 123 is attached below the passage forming member 121 in the inner frame base body 50. The opening / closing member 124 is urged to a front position that closes the main body side upper dish passage 122 and the main body side lower dish passage 123. When the front door frame 14 is opened, each opening / closing member 124 is urged by this urging force. By being in the closed state, falling off of the game balls from the passages 122 and 123 is avoided. On the other hand, in a state where the front door frame 14 is closed, the opening / closing member 124 is pushed open against the biasing force by the receiving portion provided in the passage forming unit 45 of the front door frame 14. In this state, the main body side upper dish path 122 and the front door side upper dish path communicate with each other, and the main body side lower dish path 123 and the front door side lower dish path communicate with each other.

  Next, the back configuration of the inner frame 13 (the inner frame base body 50 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 inner frame base body 50. 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 are provided on the back surface of the inner frame base body 50 for fixing the back pack unit 15 to the inner frame base body 50 in a closed state.

  As already described, the bottom portion of the housing recess (game board housing portion) 51 in the inner frame base body 50 penetrates in the thickness direction of the inner frame base body 50 and is opened to the back side of the inner frame base body 50. A window hole 52 is formed, and the window hole 52 is covered from the front side of the inner frame 13 by the game board 80 housed in the housing recess 51. Various configurations such as a control device are mounted on the back of the game board 80, and these various configurations are exposed to the back side of the inner frame 13 through the window holes 52. Here, the configuration of the back surface of the game board 80 will be described.

  A synthetic resin base body 96 on which the variable display unit 85 (see FIG. 6) is mounted on the game board 80 is fixed to the back surface of the game board 80. The base body 96 has a substantially box shape opened to the game board 80 side and covers almost the entire area of the back surface of the game board 80. A part of the base body 96 protrudes to the back side of the inner frame base body 50, and the above-described symbol display device 94 (see FIG. 6) and the symbol display device 94 for driving the protruding portion are driven. A display control device is attached. 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 inner frame base body 50). Further, the game board 80 is equipped with a notification / production control device 140 so as to be positioned behind the display control device.

  The notification / production control device 140 includes a notification / production control board that controls sound output, lamp display, and control of the display control device in accordance with instructions from the main control device described later. It is configured to be accommodated in a substrate box 141 made of a resin material or the like.

  A main controller unit 160 is provided below the notification / production control device 140 so as to cover the base body 96 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.

  A portion of the base body 96 facing the lower rear portion of the game board 80 corresponds to the game board opening of the general winning port 81, variable winning device 82, and operating ports 83a and 83b, and is located at one location on the downstream side.

That is, a fraudulent act in which a game ball (hereinafter referred to as an illegal ball) to which the tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area PE and the movement of the illegal ball or the subsequent game ball is manipulated by the yarn-like member ( There is a case where a so-called thread hanging goot is performed.

  If the illegal act is described in detail, the illegal ball is mixed with other game balls and put into the upper plate 33, and the illegal ball enters the game area PE through the ball feeding device 113 → the launch rail 112 → the guide passage 103. Let After that, by manipulating the filamentous member by hand and placing the illegal ball at a desired position, the illegal ball can be used as a guiding means for guiding the subsequent game ball to the entrance part, or the illegal ball can be entered. It is possible to misrecognize as if a large number of game balls have been won by reciprocating the illegal ball with respect to the detection area of the detection sensor provided in the ball entry part after flowing into the game part. . A privilege can be acquired illegally by such an act. Compared with fraudulent acts on the control device, such as hacking the main control device 162, etc., this fraudulent action does not require major advance preparation such as switching to a fraudulent board or adding a fraudulent board In addition, a large amount of game balls are not paid out in a short period of time compared to an illegal act that illegally generates a jackpot. Therefore, it is likely that it is difficult for the hall manager to visually detect illegal acts using illegal balls.

  One of the features of the present embodiment is that a winding mechanism 300 capable of winding a thread-like member is provided as a crime prevention structure corresponding to the suppression or suppression of fraud using the illegal ball. Accordingly, the winding mechanism 300 will be described below with reference to FIGS. 6 and 10 regarding its characteristic configuration and related configuration. FIG. 10A is a perspective view showing the winding mechanism 300, and FIG. 10B is a plan view of the winding mechanism 300.

  As shown in FIG. 6, a decorative body 86 is fixed below the game area PE of the game board 80 so as to protrude from the front surface of the plate body 80a to the front of the game machine. The decorative body 86 extends to the left and right with the out opening 89 as the center, and the general winning opening 81 and the variable winning device 82 are disposed on the decorative body 86.

  In the decorative body 86, the portion on the left side of the out port 89 is formed so that one side thereof is along the guide rail 100 (specifically, the inner rail 101), and the portion on the right side of the out port 89 is The side portion is formed along the game area partition member 99. In the following description, the left portion of the decorative body 86 is referred to as a left decorative portion 86a.

It extends so as to reach the part (hereinafter referred to as the top TP). The above-described winding mechanism 300 is provided at the upper end portion, that is, the portion that is arranged side by side with the top portion TP.

(Winding mechanism 300)
As illustrated in FIG. 10A, the winding mechanism 300 includes a shaft body 301 having a substantially cylindrical shape, and a direction intersecting with the central axis direction of the shaft body 301 from the shaft body 301 (specifically, a direction orthogonal to each other). A rotating body 303 is formed by integrating an arm 302 provided so as to protrude.

  The shaft body 301 is fixed in a state where the shaft center 311 is fitted in the center portion thereof. The shaft center 311 protrudes up and down from both end faces of the shaft body 301, and the shaft body 301 (rotary body 303) is engaged by engaging both end portions of the shaft center 311 with the bearing portion formed in the left decorative portion 86 a. Is held so as to be rotatable about the central axis CL. More specifically, the shaft body 301 is attached to the left decorative portion 86a such that the central axis CL faces the same direction as the tangent to the guide rail 100 at the top portion TP.

  Disc-shaped flange portions 312 that extend in the radial direction of the central axis CL are formed at both upper and lower ends of the shaft body 301. These flange portions 312 function as blocking means for preventing the thread-like member from moving upward or downward along the shaft body 301 and dropping off from the shaft body 301 when the thread-like member is wound around the shaft body 301. Is granted. If attention is paid to the function of preventing the thread-like member from falling off, the flange portion 312 does not necessarily have a disk shape, and may protrude at least in a direction intersecting with the central axis (preferably in a direction orthogonal). .

  Further, the winding mechanism 300 is provided with a rotation direction restricting means for restricting the rotation direction of the shaft body 301. As shown in FIG. 10B, the rotation direction restricting means is engaged with the gear portion 313 (so-called one-way gear) provided on the flange portion 312 of the shaft body 301 and the gear portion 313 provided on the left decorative portion 86a. The stopper piece 306 is formed so as to be capable of being formed. The stopper piece 306 can be displaced between an engagement position where the stopper piece 306 is engaged with the gear portion 313 and an avoidance position where the engagement with the gear portion 313 is avoided. Is being energized.

  When the shaft body 301 rotates in the forward direction (in this embodiment, it rotates in the clockwise direction when viewed from above), the stopper piece 306 is displaced along the inclination of the tooth portion of the gear portion 313 to thereby apply the biasing force. Against the evasion position. As a result, the engagement between the gear portion 313 and the stopper piece 306 is avoided, and the forward rotation of the rotating body 303 is allowed. On the other hand, when the rotating body 303 tries to rotate in the reverse direction (in this embodiment, rotating in the counterclockwise direction when viewed from above), the stopper piece 306 and the gear portion 313 are kept engaged. This prevents the reverse rotation.

  Here, the relationship between the guide passage 103 and the winding mechanism 300 will be described with reference to FIG. FIG. 11A is a schematic view showing the relationship between the winding mechanism 300 and the guide passage 103, FIG. 11B is a schematic view showing a moving path of a game ball in the guide passage 103, and FIG. 11C is a guide passage. 3 is a schematic diagram showing a relationship between a moving path of a game ball at 103 and an arm 302.

Both the slits 80b and 101b communicate with each other, and are configured such that the arm 302 can pass through when the rotating body 303 rotates. That is, as the rotating body 303 rotates, the arm 302 moves across the guide path 103. Hereinafter, for convenience of explanation, a position where the slits 80b and 101b are provided in the guide passage 103, that is, a passing position of the arm 302 is referred to as a winding position.

  Here, a supplementary description will be given of the movement of the game ball launched from the game ball launching mechanism 110. As already described, the guide rail 100 has an arc shape that protrudes to the left. For this reason, among the game balls that move along the guide rail 100, at least the game balls that are launched with a strength that can reach the game area PE are guided while being kept in contact with the outer rail 102 by centrifugal force. It moves in the passage 103 (rolls or slides). By forming the slit 101b on the inner rail 101 side, the game ball moving along the outer rail 102 comes into contact with the edge of the slit 101b in order to secure the operation area of the rotating body 303 (specifically, the arm 302). Inconveniences such as disturbed behavior are less likely to occur.

  If the arm 302 is moved so as to cross the entire area of the guide passage 103 when the guide passage 103 is viewed in a cross section orthogonal to the passage, it is possible to ensure that the arm 302 is caught by the thread-like member. However, such a configuration causes various inconveniences such as the winding mechanism 300 becoming unnecessarily large in size and restricting the arrangement.

  In consideration of such circumstances, certain limitations are set for the length of the arm 302 (slits 80b and 101b) shown in this feature. When the game ball is fired, a certain amount of tension is applied to the end of the thread-like member on the side of the illegal ball by being pulled by the illegal ball. For this reason, it is assumed that the filamentous member moves easily along a trajectory (path) through which the center of the game ball passes. Therefore, as shown in FIG. 11C, the length of the arm 302 is limited so that the position through which the center of the game ball passes is within the rotation trajectory of the arm. ing. Although details will be described later, it is not preferable that the movement of the rotating body slows when the thread-like member is entangled, and the occurrence of such inconvenience can be suppressed by shortening the length of the arm 302 as much as possible.

  In addition, when the thread-like member is set to be long so that slack or the like is generated in the passage, the above-described thread-like member may remain suspended due to its own weight. In particular, when the movement of the game ball includes a leftward displacement, that is, in a situation where the game ball is positioned below the top portion TP, the thread-like member hangs down so as to contact the outer rail 102. is assumed. In this case, there is a possibility that the winding function of the thread-like member does not work well.

  In this regard, the winding mechanism 300 in the present embodiment is arranged near the top TP, specifically, at the same height as the top TP. For this reason, even when the thread-like member hangs down due to its own weight rather than the tension from the illegal ball, it is difficult to cause the inconvenience that the thread-like member does not catch the arm 302 well.

  Here, in the case where an illegal ball to which the thread-like member is fixed is launched, if the cheating person holds the thread-like member, the movement of the game ball is likely to be hindered. Therefore, it is assumed that the thread-like member is held in a state where it can freely move to some extent so as not to hinder the movement of the game ball. That is, it is assumed that the tension generated in the thread-like member mainly contributes to the tension accompanying the launch of the illegal sphere and the own weight of the thread-like member. Therefore, a large rotational torque is not required for winding the thread-like member. In consideration of such circumstances, a mechanism related to the operation of the winding mechanism 300 is constructed.

  Specifically, the winding mechanism 300 in the present embodiment is configured such that the thread-like member can be wound based on the rotation of the rotating body 303 and the arm 302 crossing the guide passage 103. However, one of the features is that the kinetic energy of the game ball is utilized for the power for realizing such an operation. That is, the configuration for driving the winding mechanism 300 is devised from the structural side, and the momentum of the game ball immediately after being launched is utilized, thereby simplifying the configuration for driving and the like. Therefore, a configuration for realizing such movement will be described below with reference to FIGS. 10 and 12. FIG. 12 is a schematic view showing an operation mode of the winding mechanism. FIG. 12 (1) group is a longitudinal sectional view of the guide passage 103, and FIG. 12 (2) group is a transverse sectional view of the guide passage 103.

  As shown in FIG. 10A, a plurality of magnets 97 are embedded in a portion of the plate body 80a of the game board 80 where the slit 80b is formed (specifically, a portion corresponding to the tip of the arm 302). Each of these magnets 97 is provided in a one-to-one correspondence with the magnet 321 embedded in the tip portion of the arm 302, and the arm 302 fills (closes) the slit 80b by attracting the magnets 97 and 321. ) Is configured to wait in position. In the following description, a position where the slit 80b is filled (closed) is referred to as a “standby position”, and a state where the arm 302 is disposed at the standby position is referred to as a “standby state” of the winding mechanism 300 or the rotating body 303.

  The arm 302 is configured such that when the rotating body 303 is in a standby state, a part (one side portion) of the arm 302 projects into the guide passage 103 from the front surface of the plate body 80a. In order to avoid the game ball passing through the guide passage 103 from moving to the front of the gaming machine, that is, to avoid colliding with the glass unit 22, the game ball is maintained to be in contact with the front surface of the game board 80. In addition, the inclination of the guide rail 100 and the launch rail 112 game board 80 is adjusted. In other words, the game ball is configured to move easily in contact with both the outer rail 102 and the game board 80. Therefore, when the game ball passes through the guide passage 103, the game ball hits the protruding portion of the arm 302, and a rotational force is applied to the arm 302. Details of the configuration related to such an action will be described later.

  As described above, the slits 80b are closed by the arms 302. This makes it difficult for the game ball to collide with the edge of the slit 80b and disturb its behavior. Incidentally, the pressure generated between the game ball and the outer rail 102 and the pressure generated between the game ball and the game board 80 are smaller in the latter than in the former. For this reason, the guide is compared with the case where the structure corresponding to the slit 80b of the game board 80 is provided on the outer rail 102 side (that is, compared with the case where the winding mechanism 300 is provided on the outer rail 102 side). The presence of irregularities in the passage 103 is less likely to affect the behavior of the game ball.

  As shown in FIGS. 12 (a-1) and (a-2), a contact surface 322 where a game ball moving along the front surface of the plate body 80a collides with a portion of the arm 302 protruding into the guide passage 103. Is formed. The contact surface 322 is inclined so that the amount of protrusion into the guide passage 103 increases toward the far side in the guide direction in the standby state. That is, the contact surface 322 is an inclined surface having a component facing the upstream side (downward) of the guide passage 103 and a component facing the front of the gaming machine.

  When the launched game ball collides with the contact surface 322, the arm 302 is pushed rearward of the game board 80 against the magnetic force of the magnets 97 and 321. At the time of this collision, a reaction force directed toward the glass unit 22 is applied to the game ball, but the reaction force is reduced by the displacement of the contact surface 322 (arm 302) so as to escape to the back side of the game board 80. Suppressing excessive growth. That is, even if a part of the kinetic energy of the game ball is converted into the rotation energy of the rotating body 303, it is difficult for the inconvenience that the game ball easily collides with the glass unit 22 due to the configuration.

  As shown in FIG. 12B → FIG. 12C, the rotating body 303 operates when the game ball collides with the arm 302. With respect to the inclination angle of the contact surface 322 (inclination angle with respect to the front surface of the plate body 80a), it was pushed by the game ball when the game ball was fired with a strength that could reach at least a position exceeding the winding mechanism 300. The rotation energy is set such that the arm 302 can return to the standby position.

  In addition, when the arm 302 reaches the standby position shown in FIG. 12A, the rotating body 303 that has started rotating moves so as to remain at the standby position by the magnetic force of each of the magnets 97 and 321. It will be disturbed. Specifically, in the rotating body 303, the energy received when the game ball collides is attenuated by the friction between the shaft center 311 and the bearing portion. In consideration of such circumstances, the magnetic force (holding force) of the rotating body 303 is reduced when the impact force exceeds the holding force when the game ball collides, and when the momentum decreases due to rotation and returns to the standby position. It is set so that the movement can be stopped.

  According to such a configuration, as shown in FIG. 12 (a) → FIG. 12 (b) → FIG. 12 (c) → FIG. 12 (a), a game is played under a situation where a normal game ball is repeatedly fired. Each time the ball is launched, the rotating body 303 moves from the standby position and makes one rotation, and then returns to the standby position again.

  Here, a security function by the winding mechanism 300 using the above operation principle will be described with reference to FIG. FIG. 13 is a schematic view showing the winding state of the thread-like member. FIG. 13 (1) group shows a horizontal section of the guide passage 103, and FIG. 13 (2) group shows the relationship between the rotating body 303 and the thread-like member. Show.

  As shown in FIG. 13A, when the illegal ball launched from the game ball launching mechanism 110 reaches the winding position where the slits 80b and 101b are provided, the illegal ball collides with the arm 302 (specifically, the contact surface 322). To do. As a result, the rotating body 303 starts moving to the side where the arm 302 moves away from the guide passage 103.

  As shown in FIG. 13A → FIG. 13B, the thread-like member remains in the guide passage 103 even after the illegal ball has passed the winding position. The arm 302 once moves away from the thread-like member and then returns to the guide passage 103 again through the slit 101b. Then, it comes into contact with the thread-like member from the front of the gaming machine (see FIG. 13B → FIG. 13C).

  As already described, a certain tension is generated by pulling the thread-like member by the illegal ball. For this reason, when a portion close to an irregular sphere in the filamentous member is to be wound, the rotational torque necessary for winding the filamentous member tends to increase. On the other hand, the length of the thread-like member is secured to some extent from the actual state of the fraudulent act in which a fraudulent person operates the hand (in front of the gaming machine) to adjust the position of the fraudulent ball. is assumed. Therefore, it is easy to suppress the required rotational torque by winding up the part that is some distance away from the illegal sphere rather than taking up the part close to the illegal sphere.

  Therefore, as shown in FIG. 13 (a) → FIG. 13 (b) → FIG. 13 (c), when the illegal ball passes the winding position, the arm 302 does not immediately move toward the thread-like member. By moving away from the thread-like member and then approaching the thread-like member again, a certain amount of time lag can be generated in the winding (contact) of the thread-like member. This makes it possible to achieve the purpose of reducing the rotational torque necessary for winding the above-described thread-like member.

  Thereafter, as shown in FIG. 13 (c) → FIG. 13 (d), when the rotating body 303 returns to the standby state, the thread-like member is caught by the rotating body 303, and the movement of the illegal ball is prevented.

  In the configuration in which the filamentous member is wound by rotation as shown in the present embodiment, the relationship between the tension of the filamentous member and the rotational torque at the time of rotation greatly affects the operation of the winding mechanism 300. That is, there is a large difference in rotational torque required between pushing (winding) the thread-like member at the distal end portion of the arm 302 and pushing (winding) the thread-like member at the proximal end portion of the arm 302. Therefore, the arm 302 shown in this embodiment is provided with guiding means for guiding the thread-like member from the distal end side to the proximal end side of the arm 302 in accordance with the operation of the rotating body 303.

  Specifically, as shown in FIG. 10B, on the side opposite to the side where the contact surface 322 is provided in the arm 302, the thread-like member is placed on the base end side (rotation center side) of the arm 302. A guiding inclined surface 323 for guiding is formed. The guide inclined surface 323 is formed so that the distance from the front surface of the plate body 80a is relatively large at the distal end portion and relatively small at the proximal end portion in the standby state. According to such a configuration, the thread-like member pushed by the arm 302 (guidance inclined surface 323) is guided to the rotation center side of the rotating body 303 together with the rotation of the arm 302 (see FIG. 13D). .

  In the state shown in FIG. 13D, the thread-like member is attracted to the outside of the guide passage 103, and further movement (flowing down) is hindered by the hooking (friction or the like) between the thread-like member and the rotating body 303. .

  As already explained, from the timing of FIG. 13 (a) when the illegal sphere passes the winding position to the timing of FIG. 13 (d) where the movement of the illegal sphere is prevented by the winding of the thread-like member being executed. This movement will be continued. And the operation | movement aspect of the winding mechanism 300 is defined so that it may be in the state which the game ball has already reached | attained game area PE at the timing of FIG.13 (d).

  In other words, the game ball that has flowed into the game area PE is prevented from flowing down due to its own weight, and the fraudulent person pulls the thread-like member, etc. to temporarily raise the game ball within the game area PE to try to flow again. However, the game ball will not flow down properly due to its own weight. This makes it difficult to freely adjust the position of the illegal sphere in the game area PE.

  Further, in the present embodiment, when the subsequent game ball passes through the winding position, the rotating body 303 is rotated again, and the thread-like member is further wound (see FIG. 13E). In addition, the thread-like member is entangled with both the shaft body 301 and the arm 302, and even if the fraudulent pulls the thread-like member, it is difficult for the thread-like member to slide on the rotating body 303 itself. Can be. Further, since the movement of the thread-like member in the central axis direction is prevented by the arm 302, it is possible to avoid the thread-like member from dropping from the shaft body 301.

  Most of the guide passage 103 is covered with the front door frame 14 so as not to be visible. And considering that the launch interval of the game balls is set to be 0.6 sec, at the timing when the illegal ball actually reaches the game area PE and the cheating person visually confirms the game ball It is assumed that the next game ball is being fired and the state shown in FIG. 13 (e) is likely to occur. Certainly, if the game balls are fired one by one, the transition to the state shown in FIG. 13 (e) is avoided. However, such a launching operation is called a so-called irregular stroke, and it is easy to draw attention from the surroundings. Therefore, it becomes difficult to carry out the launching operation in such a manner that the degree of freedom of movement of the illegal sphere is assumed to be higher than that shown in FIG. It can be suitably exhibited.

  In addition, it is very uncomfortable when viewed from the surroundings to stop the operation of launching the game ball after flowing the illegal ball into the game area PE and concentrate on the operation of the threaded member. In this case, it is assumed that the game ball is continuously fired together with the operation of the thread-like member. Also for this reason, it is assumed that the winding of the thread-like member is promoted, and as a result, the illegal act itself becomes difficult and the crime prevention function is suitably exhibited.

  The operation mode exemplified above is a case where the winding of the thread-like member is successful, but there is a possibility that the winding function does not work well when the tension is actually strong. However, even in such a case, the arm 302 remains in the guide passage 103, specifically in a position in contact with the thread-like member or a position where the thread-like member is slightly pushed to the slit 80b side. The rotation of 302 is promoted. Even if the game ball does not hit the contact surface 322 of the arm 302, for example, and the rotation promotion effect cannot be enjoyed, the arm 302 functions as a barrier in the guide passage 103, so that the subsequent game ball Can be prevented from reaching the game area PE.

  Further, when the arm 302 pushed by the subsequent game ball moves beyond the standby position and stays in the slit 80b, for example, the movement of the thread-like member is prevented as in FIG. 13D. Thus, it is difficult to move the illegal sphere to a desired position. Furthermore, when the slit 80b is opened and the subsequent game ball collides with the edge of the slit 80b, the behavior is disturbed, and it is difficult to make the subsequent game ball reach the game area PE itself. be able to.

  For the above reasons, when an illegal act is attempted using an illegal sphere to which the thread-like member is fixed, the thread-like member is wound by the winding mechanism 300 to manipulate the thread-like member to move the illegal sphere. It becomes difficult. In addition, in a state where a certain number of times of winding has been performed, even if the fraudster forcibly pulls the thread-like member and cuts the thread-like member in order to conceal the evidence, the illegal ball with the thread-like member in the game area PE It will remain hanging and it will be difficult to conceal the traces of fraud.

  In the present embodiment, disposing the take-up mechanism 300 at a position where it can be viewed from the front of the gaming machine can appeal that fraud itself is difficult, and can contribute to suppression of fraud.

  Further, since the winding mechanism 300 is disposed at a position where it can be visually recognized, even if the winding mechanism 300 malfunctions for some reason, the hall manager can easily grasp the fact visually. Furthermore, since the shaft body 301 can be accessed only by opening the front door frame 14, it is easy to rotate the shaft body 301 with a finger or the like to return the arm 302 to the standby position. It is.

  Here, when the position of the illegal ball is adjusted by operating the thread-like member in a state where the illegal ball has flowed into the game area PE, the thread-like member is at least the inner rail on the downstream side (above) from the top portion TP. It exists in the position which follows 101. As long as the thread-like member is present along the inner rail 101 as described above, the arm 302 is approximately half the width of the guide passage 103 in order to exhibit the winding function of the thread-like member. It will be enough. In other words, the arm 302 (specifically, the contact surface 322) and the subsequent game ball need only be guaranteed to collide with each other when the thread-like member is wound up by the subsequently launched game ball instead of the illegal ball itself. The length of 302 can be shortened to contribute to the downsizing of the winding mechanism 300.

<Second Embodiment>
In the first embodiment described in detail above, simplification of the structure related to the winding mechanism 300 has been realized by configuring the winding mechanism 300 to operate using the kinetic energy of the game ball. In order to emphasize further improvement, it is effective to separately provide a power source for operating the winding mechanism 300 as shown in the present embodiment. In such a configuration, the idea level of operating the winding mechanism 300 based on the launch of the game ball is the same as that of the first embodiment, but this is not from a structural aspect but from an electrical aspect. The configuration is different in that it is realized.

  Hereinafter, with reference to FIG. 14, the structure concerning the drive of the winding mechanism 300 in this Embodiment is demonstrated. FIG. 14 is a block diagram showing an electrical configuration related to the winding mechanism in the gaming machine according to the second embodiment. Note that the winding mechanism 300 in the present embodiment is basically the same as that in the first embodiment, and therefore, the description of the common configuration will be provided with a focus on different configurations.

  The winding mechanism 300 includes a drive motor 351 as a rotation drive unit that rotates the rotating body 303. The drive motor 351 is built in the left decorative portion 86a, and its power is transmitted to the shaft center 311 (shaft body 301) via a gear or the like (not shown) constituting the drive force transmitting means. .

  The drive motor 351 is connected to the output port of the power / fire control board 248 in the power / fire control device 243 and operates when a drive signal is input from the power / fire control board 248. As described above, the contact surface 322 of the arm 302 is not necessary in conjunction with the separate preparation of the drive source, and the contact surface 322 is omitted. However, with respect to the arm 302, the slit 80b is closed in a state where the arm 302 is disposed at the standby position, so that the game ball passing through the winding position is prevented from coming into contact with the edge of the slit 80b and disturbing its behavior. About the point, it is the same as that of the said 1st Embodiment.

  The drive motor 351 is a stepping motor, and has a configuration in which the rotational position of the rotating body 303 (arm 302) is managed by the number of pulses. Specifically, the number of pulses of the output drive signal is set so that the rotating body 303 makes one rotation when the signal is input to the drive motor 351. For this reason, normally, every time a drive signal is output, the rotator 303 leaves the standby position and returns to the standby position again.

  The winding mechanism 300 includes a position detection sensor 352 as monitoring means for monitoring whether or not the arm 302 is disposed at the standby position. The position detection sensor 352 is connected to the input port of the power / fire control board 248, and the position information (detection signal) of the arm 302 is input to the power / fire control board 248. Thereby, the power source / launch control device 243 can grasp whether or not the winding mechanism 300 is in a standby state.

  The game ball launch handle 41 is connected to the input port of the power / fire control board 248, and operation information (operation signal) of the game ball launch handle 41 is input to the power / fire control board 248. It has a configuration. The operation information includes information as to whether or not the player is touching the game ball launch handle 41 and information related to the amount of rotation operation.

  Here, the launch control process executed by the MPU 249 (see FIG. 14) of the power / launch controller 243 will be described with reference to the flowchart of FIG. The launch control process is a process that is executed as part of a normal process that is periodically executed (for example, every 0.4 sec) by the power source / fire control device 243.

  In the launch control process, it is first determined in step S101 whether or not a predetermined period (0.6 sec in the present embodiment) has elapsed since the previous game ball launch. If an affirmative determination is made in step S101, it is determined in step S102 whether or not a launch operation is being performed. Specifically, the determination is executed based on operation information from the game ball launch handle 41.

  If a negative determination is made in either step S101 or S102, it is determined that the game ball firing condition is not satisfied, and the present firing control process is terminated as it is.

  On the other hand, if an affirmative determination is made in step S102, the game ball firing condition is satisfied. In step S103, therefore, a process for determining the launch intensity (launch speed) of the game ball is executed. Specifically, the voltage level of the drive signal output to the solenoid 111 is determined based on the information regarding the operation amount received from the game ball launching handle 41.

  In subsequent step S104, a game ball launching process is executed in accordance with the decision items in step S103. That is, a drive signal having a voltage level set in the solenoid 111 is output. Thereafter, in step S105, the winding mechanism drive timing setting process is executed, and the main firing control process is terminated.

  The drive timing of the winding mechanism is stored in a state associated with the operation amount of the game ball launch handle 41, and the drive timing is determined with reference to this stored information (timing determination table). . Specifically, the time required from passing the game ball to passing the winding position can vary depending on the launch strength of the game ball. Therefore, in the timing determination table, the output timing of the drive signal set so that the winding mechanism starts to operate at the timing after the game ball passes the winding position is stored. Regarding the timing information and drive signal output period stored in the timing determination table, the operation of the winding mechanism 300 based on the previous game ball firing is completed before the subsequent game ball reaches the winding position. Is set to be able to. This prevents the arm 302 of the take-up mechanism 300 from interfering with the game ball during a normal game.

  Next, the winding mechanism driving process will be described with reference to the flowchart of FIG. The winding mechanism driving process is also a process that is executed as part of the normal process, similar to the firing control process.

  In the winding mechanism driving process, first, in step S201, it is determined whether or not it is the driving timing of the winding mechanism 300. Specifically, it is determined whether or not the driving timing determined in step S105 has come.

  When an affirmative determination is made in step S201, the process proceeds to step S202, and a winding mechanism driving process is executed. Specifically, a drive signal is output to the drive motor 351 of the winding mechanism 300. As a result, the rotating body 303 rotates.

  On the other hand, if a negative determination is made in step S201, the process proceeds to step S203, in which it is determined whether or not the arm 302 is present at the standby position. Specifically, it is determined based on detection information from the position detection sensor 352 whether or not the arm 302 has returned to the standby position within a preset period.

  Normally, in a situation where there is nothing that prevents the rotation of the rotating body 303, the arm 302 returns to the standby position after the operation is completed. Therefore, in many cases, an affirmative decision is made in step S203, and the main winding mechanism driving process is terminated as it is.

  On the other hand, when a drag force that prevents the rotation of the rotating body 303 occurs due to the use of the above-described illegal ball with a thread-like member, the drag force may exceed the rotational torque of the rotating body 303. . In such a case, there is a possibility that the return of the rotating body 303 to the standby position is not completed.

  In such a case, a negative determination is made in step S203, and the process proceeds to step S204. Thereafter, the re-drive process is executed in step S204, and the winding mechanism drive process is terminated.

  In the re-drive process, a drive signal is output to the drive motor 351 so that the arm 302 returns to the standby position. This drive signal is continuously output until the arm 302 returns to the standby position. If the return of the arm 302 to the initial position is not realized, the voltage level of the drive signal output to the drive motor 351 is The output mode of the drive signal is changed so as to increase sequentially. When the arm 302 returns to the standby position, the output of the drive signal is stopped.

  In the present embodiment in which the drive system is changed to the electric one, the load applied to the drive motor 351 increases during the winding process of the thread-like member. In other words, when the load increases, there is a possibility that an illegal sphere is being used. Therefore, when such a situation occurs, a configuration for notifying that effect is adopted. Hereinafter, a preparation process (load detection process) for executing the notification will be described with reference to the flowchart of FIG. Note that the load detection process is also a process that is executed as part of the normal process that is periodically executed (for example, every 0.4 sec) by the power source / fire control device 243, similarly to the launch control process.

  In the load detection process, first, in step S301, it is determined whether or not the drive motor 351 is being driven. If a negative determination is made in step S301, the load detection process is terminated as it is.

  On the other hand, if an affirmative determination is made in step S301, the process proceeds to step S302, and load detection processing is executed. Specifically, the load is detected based on the increase in the voltage output to the drive motor 351 in the re-drive process (step S204) of the winding mechanism drive process.

  In a succeeding step S303, it is determined whether or not the load detected in the step S302 exceeds a preset threshold value. Actually, the rotating body 303 is set to return to the standby state by one rotation by the winding mechanism driving process in step S202, but it may be assumed that the return is not completed due to a malfunction or the like. Therefore, in step S303, an increase in load due to such a mere malfunction and an increase in load due to fraud are determined based on the magnitude of the load (based on the threshold).

  Here, with reference to the timing chart of FIG.16 (b), it demonstrates about the increase aspect of the load when a fraudulent act is performed.

  As already described, in the present embodiment, on the condition that the game ball launch handle 41 is operated, the launch of the game ball is repeated at a predetermined cycle. When a normal game ball is being fired, as shown in the timings ta1 to ta3, the load generated in the drive motor 351 for operating the winding mechanism 300 is sufficiently higher than a preset threshold value. It is low. On the other hand, when an illegal ball is launched, a drive signal is output to the drive motor 351 at the timing ta4 slightly delayed from the launch timing. At this time, the load does not increase until the arm 302 contacts the initial stage of rotation, that is, the thread-like member. Here, when the movement of the arm 302 is prevented by the thread-like member and the arm 302 cannot be returned to the standby position, the output of the drive motor 351 is sequentially increased at the timing ta5. Thereby, the arm 302 moves to the standby position while winding the thread-like member. In this way, when the output of the drive motor 351 increases, the load detected in the load detection process in step S302 increases, and when the load exceeds the threshold value (see timing ta6), an affirmative determination is made in step S303. do. That is, it is determined that there is a possibility that an illegal act is performed instead of a simple malfunction. If an affirmative determination is made in step S303, the process proceeds to step S304.

  In step S304, an abnormal signal output process is executed. Specifically, information corresponding to the occurrence of an abnormality is output to main controller 162. Based on this information, the MPU 169 of the main control device 162 outputs an abnormality notification command to the notification / production control device 140. Based on the reception of this command, the notification / production control device 140 executes a process of turning on the error display lamp unit 27 and transmits the abnormality notification command to the display control device 150. The display control device 150 displays a message such as “Please call a staff member” on the display screen 94a based on the reception of the abnormality notification command. This can contribute to early detection of fraud.

  When the thread-like member is wound by the winding mechanism 300, it is assumed that the drag that prevents the rotation of the rotating body 303 increases as described above. The generation of such a drag can be a factor that hinders the return of the arm 302 to the standby position. Certainly, there may be a case where the arm 302 does not return to the standby position due to a malfunction, but in this case, it is easily solved by driving the rotating body 303 again. On the other hand, when winding the thread-like member as described above, the load varies greatly depending on the tension of the thread-like member and the number of windings, and the load is not easily eliminated. Therefore, in such a case, it is possible to determine the presence or absence of cheating by comparing a preset threshold value with a load. As a result, it is possible to notify the hall manager or the like that there is a possibility of fraud, and it is possible to contribute to further improvement of the crime prevention function.

  In addition, the configuration in which the arm 302 is forcibly returned to the standby position by the drive motor 351 can prevent the arm 302 from remaining in the guide passage 103. Thereby, the chance that a game ball collides with the arm 302 can be reduced, and the winding mechanism 300 can be protected.

  Note that the modification shown in the first embodiment can also be applied to this embodiment. That is, when the position of the illegal ball is adjusted by operating the thread-like member in a state where the illegal ball flows into the game area PE, the inner rail 101 is at least downstream (upward) from the top TP. It exists in the position along. As long as the thread-like member is present along the inner rail 101 as described above, the arm 302 is approximately half the width of the guide passage 103 in order to exhibit the winding function of the thread-like member. It will be enough. Here, in the present embodiment, it is not necessary to rotate the rotating body 303 using the kinetic energy of the game ball, so that the length of the arm 302 can be further shortened when applying the modification. It is. As a result, it is possible to improve the response during rotation, and the winding operation can be made more rational.

<Third Embodiment>
In the configuration in which the game ball is guided to the game area PE via the guide passage 103, the game ball can be charged by rubbing against the guide rail 100 and the front surface of the game board 80 (plate body 80a). The charged game ball generates noise, and the noise may affect the operation of various electric devices such as the detection sensor and the control device described above. In particular, immediately after a game ball is fired from the game ball launching mechanism 110, it is assumed that the above-mentioned charging is likely to occur because the game ball moves vigorously, and there is a concern that the metallic guide rail itself is also charged. That is, the game ball and the guide rail 100 released to the game area PE are likely to be in a state where the noise is likely to be generated.

  One of the features of the present embodiment is that a configuration for eliminating such inconvenience is employed. Hereinafter, the characteristic configuration will be described with reference to FIGS. 17 to 18. FIG. 17 is a front perspective view showing the structure of the inner frame base body 50 in the third embodiment, FIG. 18 is a front view showing the structure of the game board 80 in the third embodiment, and FIG. FIG. In addition, since the basic structure of the pachinko machine 10 is the same as that of the first embodiment, the following description will focus on differences from the first embodiment.

  First, a configuration for mounting the game board 80 will be described, and then a characteristic configuration in the present embodiment will be described.

(Mounting structure of game board 80)
In the present embodiment, a characteristic configuration is provided for the mounting structure of the game board 80. As already explained, the game board 80 is fitted from the front side of the inner frame 13 to the housing recess 51 of the inner frame 13 (see FIG. 5). As shown in FIG. 17, the housing recess 51 is formed by a flat plate-like facing portion 53 that is provided in the inner frame base body 50 and faces the back surface of the game board 80, and a peripheral wall portion 54 that extends along the periphery of the game board 80. The region surrounded by the facing portion 53 and the peripheral wall portion 54 is an accommodation region for the game board 80 (specifically, the plate body 80a).

  The opposed portion 53 is formed with the above-described window hole 52 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 54 is composed of an upper side wall portion 61, a lower side wall portion 62, a left side wall portion 63, and a right side wall portion 64 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 54 is formed so as to surround the window hole 52.

  The inner frame base body 50 is formed using a synthetic resin material, and metallic vertical frame members 55 and 56 are fixed to the left and right frame portions thereof. Both the vertical frame members 55 and 56 extend so as to straddle the upper end portion and the lower end portion of the inner frame base body 50, and a metallic horizontal frame member 57 in which an intermediate portion of both the frame members 55 and 56 extends to the left and right. Are connected by By using the metal frame members 55 to 57, it is possible to reduce the thickness of the inner frame base body 50, so that both the weight reduction of the inner frame base body 50 and the strength guarantee are achieved. If the horizontal frame member 57 is supplementarily described, the horizontal frame member 57 is disposed along the lower side wall portion 62 and is fixed to the lower side wall portion 62, whereby a reinforcing member for the lower side wall portion 62 is provided. Is functioning as

  The left vertical frame member 55 is formed on a long plate portion that vertically extends with the plate surface facing the left wall portion 63 and along the left wall portion 63, and front and rear ends of the long plate portion (inside the gaming machine) And a horizontal section having a substantially U shape opened to the window hole 52 side. The portion of the facing portion 53 that is on the rotation base end side of the front door frame 14 is covered from the front of the gaming machine by a flange portion 55a that is configured to face the facing portion 53 in the vertical frame member 55. The vertical frame member 55 and the inner frame base body 50 are integrated by screwing the flange portion 55a to the facing portion 53.

  The left side wall 63 of the inner frame base body 50 is provided with a stopper 68 that suppresses the displacement of the gaming board 80 in the biasing direction by contacting the front surface of the gaming board 80. The stopper 68 protrudes from the inner wall surface of the left side wall portion 63 into the housing recess 51, and is formed such that the distance between the stopper 68 and the facing portion 53 is equal to the thickness of the game board 80 (more Specifically, it is formed to be slightly smaller).

  In addition, if it supplements regarding arrangement | positioning of the stopper 68, these stoppers 68 are arrange | positioned in the said guide rail 100 above and below the part (top part TP) which protrudes in the rotation base end side of the game board 80. FIG. Thereby, the stopper 68 that abuts against the front surface of the game board 80 and the guide rail 100 that partitions the game area PE on the front surface of the game board 80 can preferably coexist on the front side of the game board 80. It has become.

  The insertion portion 69 into which one side portion of the game board 80 can be inserted is constructed by the flange portion 55a described above in detail and the pair of stoppers 68 disposed above and below. The insertion portion 69 is arranged on the rotation base end side of the front door frame 14 and the rotation front end side of the inner frame 13 to allow insertion of the game board 80 from the rotation front end side of the inner frame 13. It is open to.

  Below the insertion portion 69, specifically, at a position where the left side wall portion 63 and the lower side wall portion 62 intersect in the inner frame 13, a temporary placement portion 66 that can temporarily place the game board 80 inserted into the insertion portion 69 is provided. ing. The upper end surface of the temporary placement portion 66 is positioned above the other portions of the lower wall portion 62 and has a planar shape facing the lower end portion of the game board 80. On the other hand, a notch 90 corresponding to the temporary placement portion 66 is formed in the lower corner portion of the rotation base end side of the game board 80 (see FIG. 18). In the initial stage where the game board 80 is inserted into the insertion portion 69 and starts to rotate, the notch 90 of the game board 80 is temporarily placed (temporarily placed) with respect to the temporary placement portion 66. At least a part of the weight of the board 80 is supported by the inner frame base body 50. This reduces the work load and facilitates the turning operation of the game board 80.

  In a state where the game board 80 is disposed at the mounting completion position, the lower end portion of the game board 80 rests on the lower side wall part 62, that is, the upper surface of the lower side wall part 62, and the temporary placement part 66 and the notch part 90 described above There is a slight gap between them. The game board 80 is supported by the lower side wall part 62 by being placed on the lower side wall part 62, and the vertical position thereof is defined. In this way, if attention is paid to the point that the placed game board 80 is supported from the lower side, the lower side wall portion 62 can also be referred to as a “placement portion” or a “support portion”.

  A guide portion (not shown) for guiding the game board 80 to the upper surface of the lower wall section 62 when the game board is mounted is formed at the front end portion of the lower wall section 62. The guide portion is arranged at a position where the lower end edge of the game board 80 can come into contact when the game board is rotated, and is inclined downward toward the front side of the inner frame 13. When the game board 80 is rotated from the state placed on the temporary placement part 66 toward the mounting completion position, the lower end part of the game board 80 hits the guide part at an intermediate stage, and the game board 80 is inclined to the guide part. Pushed up along. As a result, the notch portion 90 is separated from the temporary placement portion 66 and the lower end portion of the game board 80 is placed on the lower wall portion 62, and the weight load of the game board 80 is transferred from the temporary placement portion 66 to the lower wall portion 62. Will move.

  The lower wall portion 62 is located between the game ball launching mechanism 110 and the game board 80, and the vertical position of the game board 80 is defined at a position close to the game ball launching mechanism 110. As already described, both the entrance portion 104 of the guide rail 100 and the game ball launching mechanism 110 are arranged along the lower side wall portion 62. This makes it easy to suppress variations in the landing position of the game balls launched from the game ball launching mechanism 110 on the guide rail 100.

  As already described, the lower side wall 62 is made of synthetic resin. For this reason, when it is going to support the load of the game board 80 with the lower side wall part 62, the countermeasure of enlarging the thickness of the lower side wall part 62 is needed.

  In this respect, in the pachinko machine 10 shown in the present embodiment, a metal horizontal frame member 57 that supports the lower wall portion 62 from below is provided separately, and the lower wall portion 62 and the horizontal frame member 57 are used in combination. Supporting strength is achieved while suppressing the occurrence of As already described, the horizontal frame member 57 is a long member extending left and right, and its left and right ends are connected to both vertical frame members 55 and 56. Thereby, not only the support function of the lower side wall part 62 (enhancement of the support strength of the game board 80) but also the strength improvement of the entire inner frame base body 50 is realized.

  Here, with reference to FIG. 18, the game board 80 in this Embodiment and the structure relevant to it are demonstrated.

  In the game board 80 in each of the above embodiments, the plate body 80a is made of a wooden plate material and a sheet material. However, the plate body 80a in this embodiment is made of a synthetic resin material having transparency. . Thereby, the back of the game board 80 can be visually recognized through the plate 80a. In conjunction with such a change, it is possible to improve the appearance of the game board 80 using the back of the game area PE by arranging various decorative bodies such as a light emitting portion behind the plate body 80a. .

  A front door frame 14 is disposed in front of the game board 80, and the game board 80 is covered by the front door frame 14 from the front of the gaming machine. As already described, the window portion 21 is formed in the front door frame 14, and the game area PE is visible through the window portion 21. However, the front door frame 14 is provided with an annular illumination part 26 (specifically, a side lamp part 26a) on both the left and right sides of the window part 21 so as to protrude forward of the gaming machine. Due to the presence, a part of the front surface of the game board 80 cannot be visually recognized through the window portion 21 (see a two-dot chain line in FIG. 18A).

  Certainly, the window portion 21 is enlarged in accordance with the expansion of the game area PE, and a part of the game board 80 is annular although the annular electric decoration portion 26 at the side portion of the window portion 21 is thinned. It is hidden behind the illumination part 26. Specifically, the guide rail 100 is arranged close to the left side so that the edge of the game board 80 is in the left limit position, but the entire area of the guide passage 103 is not visible, but is described above. In the vicinity of the top portion TP, the guide passage 103 is covered from the front side of the gaming machine by the side ramp portion 26a.

(Antistatic structure)
Most of the above-described antistatic structure for preventing charging of a game ball or the like is covered by the annular electric decoration part 26 or the frame body 20 of the front door frame 14 in the game board 80 (specifically, the part corresponding to the guide passage 103). It is arranged in the part which is broken.

  As shown in FIG. 18B, leg portions 101 a and 102 a extending rearward are formed in the vicinity of the top portion TP covered with the annular illumination portion 26 in each rail 101 and 102. The leg portions 101a and 102a are arranged so as to face each other across the guide passage 103 when viewed from the front of the game board 80 (lined up in a direction orthogonal to the passage direction of the guide passage 103 near the top TP). Is placed). The tip portions of the leg portions 101a and 102a protrude to the back side of the plate body 80a through through holes formed in the plate body 80a. A metal conductive member 400 is provided behind the plate body 80a (specifically, the guide passage 103) and covered with the side lamp portion 26a, and the conductive member 400 has legs 101a and 102a. They are arranged so that they are connected.

  That is, by connecting the leg portions 101 a and 102 a to the conductive member 400, the rails 101 and 102 and the conductive member 400 are electrically connected. A wiring 401 is attached to the end of the conductive member 400, and this wiring is connected to a metal center frame 95. Then, when the center frame 95 is electrically connected to the horizontal frame member 57 via a wiring (not shown), the charge generated in the guide rail 100 and the charge stored in the game ball are changed from the conductive member 400 to the wiring 401. → A configuration in which the horizontal frame member 57 is discharged (grounded) through the center frame 95 is realized. Thereby, it is possible to avoid the inconvenience caused by the above-described charging.

  Further, as shown in FIG. 19, the conductive member 400 has a plate shape, and a recess formed in accordance with the conductive member 400 is formed on the back surface of the plate body 80a. The depth dimension of the concave portion is the same as the plate pressure dimension of the conductive member 400, and the back surface of the plate body 80a is located on the same plane as the back surface of the plate body 80a. The conductive member 400 is disposed at the left end portion of the plate body 80 a so that a part of the plate surface faces the flange portion 55 a of the standing frame member 55.

  For this reason, in a state where the game board 80 is mounted on the inner frame base body 50, the flange portion 55a of the vertical frame member 55 and the conductive member 400 come into contact with each other. Thereby, the structure by which the electric charge stored in the guide rail 100 or the game ball is discharged (grounded) from the conductive member 400 to the vertical frame member 55 is realized. In this way, by setting a plurality of charge discharge routes, it is possible to suitably exhibit the antistatic function. Of the two ground paths described above, the former requires the work of releasing the connection between the wiring and the lateral frame member 57 when the game board 80 is removed, while the latter is released by the work of removing the game board 80 itself. Is done.

  When the appearance of the gaming board 80 is improved by making the plate body 80a transparent, the structure (the conductive member 400 and the vertical frame member 55) relating to antistatic can be visually recognized. This is not preferable. In this regard, as shown in the present embodiment, the structure (conductive member 400 and vertical frame member 55) for preventing electrification is placed at a position (behind the side lamp portion 26a) where it is impossible or difficult to see from the front of the gaming machine. By arranging, the above-described deterioration in appearance can be suppressed.

<Fourth embodiment>
In the third embodiment, the antistatic conductive member 400 is disposed near the top TP of the guide rail 100, but there is room for improvement in improving the antistatic function of the game ball. . In this embodiment, the antistatic function is further improved by devising the arrangement of the conductive member 500. Hereinafter, the antistatic structure in the present embodiment will be described with reference to FIGS. FIG. 20 is a front view showing the structure of the game board in the fourth embodiment, and FIG. 21 is a partially enlarged view of FIG. 20 showing the vicinity of the outlet portion 105 of the guide passage 103. Since various configurations such as the mounting structure of the game board 80 are the same as those in the third embodiment, the description will be referred to and the description will focus on differences from the third embodiment.

  Most of the game balls flowing into the game area PE are separated from the outer rail 102 at a position beyond the exit portion 105 of the guide passage 103. In other words, when playing a game, the game ball passing through the guide passage 103 is kept in contact with the guide rail 100 (specifically, the outer rail 102) at least until the vicinity of the exit portion 105. For this reason, if it is going to exhibit the earthing function shown in 3rd Embodiment more suitably, it is preferable to earth in the part (part close | similar to the exit part 105) which is as downstream as possible in the guidance path 103. FIG.

  In consideration of such circumstances, the conductive member 500 in the present embodiment is disposed at the exit portion 105 of the guide rail 100 (see FIG. 20).

  Here, the arrangement of the conductive member 500 will be supplementarily described with reference to a partially enlarged view (FIG. 21) of FIG.

(Conductive member 500)
As shown in FIG. 21, the rear side of the plate body 80 a is formed in the end portion (tip portion) of the inner rail 101 that forms the outlet portion 105 through a through hole formed in the plate body 80 a of the game board 80. A leg portion 101a is formed extending in the direction. On the other hand, a portion of the outer rail 102 that constitutes the outlet portion, more specifically, a portion facing the inner rail 101 across the outlet portion, is provided on the back side of the plate body 80a through a through hole formed in the plate body 80a. A leg portion 102a is formed extending in the direction. A conductive member 500 is attached to the back side of the plate body 80a, and the leg portions 101a and 102a are connected to the conductive member 500.

  More specifically, the conductive member 500 has a plate-like mounting base 501 that faces the back surface of the plate body 80a. The mounting base 501 has a substantially rectangular shape, and the leg portion 101a is connected to the central portion thereof. The mounting base 501 is arranged so that one of its four corners faces the outer rail 102 side, and an extension portion 502 extending to the outer rail 102 is formed at this corner portion. The distal end portion of the extension portion constitutes a connection portion with the leg portion 102a.

  The plate member 80a is formed with a recess capable of accommodating the conductive member 500 (specifically, the mounting base 501 and the extending portion 502) as in the third embodiment, and the back surface of the conductive member 500 is the plate member 80a. It is located on the same plane as the back surface. Although illustration is omitted, in a state where the game board 80 is mounted on the inner frame base body 50, the conductive member 500 and the flange portion 55a of the vertical frame member 55 are in surface contact as in the third embodiment, and the grounding is performed. Function will be secured.

  In this way, by grounding in the vicinity of the exit portion 105 of the guide passage 103, charging of the game ball and the guide rail 100 can be more suitably suppressed.

  Also in the present embodiment, the plate body 80a is made of a synthetic resin material having transparency, and the exit portion 105 of the guide passage 103 is visible from the front of the gaming machine through the window portion 21 of the front door frame 14. It is possible. Therefore, the presence of the conductive member 500 can be visually recognized from the front of the gaming machine, and the configuration shown in the third embodiment is more advantageous in improving the appearance of the gaming machine.

  However, in the present embodiment, a contrivance has been made in which the conductive member 500 is visible and easily noticeable. Hereinafter, the configuration according to the device will be described with reference to FIG. 21 and FIGS. 22 (a) is a front perspective view of the conductive member 500, FIG. 22 (b) is a partial cross-sectional view taken along the line EE of FIG. 22 (a), and FIG. 22 (c) is an FF of FIG. 22 (a). FIG.

  As shown in FIG. 21, a reverse prevention member 106 is arranged on the extension in the guiding direction of the tip portion constituting the outlet portion 105 in the inner rail 101. The anti-reverse member 106 includes a plate-like base body 107 fixed to the front surface of the game board 80 (plate body 80 a) and a movable piece 108 provided to be rotatable with respect to the base body 107.

  In the inner rail 101, a slight gap is formed between the tip portion constituting the outlet portion 105 and the reverse return preventing member 106. A through hole 80c is formed in the plate body 80a so as to penetrate the plate body 80a in the front and back of the plate body 80a in a range including the gap.

  The mounting base 501 is integrally formed with an upright portion 503 that stands in front of the gaming machine. When the conductive member 500 is fixed to the plate body 80a, a part of the upright portion 503 passes through the through hole 80c. It projects to the front side of 80.

  The upright portion 503 is formed so as to straddle two adjacent end portions in the mounting base 501, and is a first plate formed so as to intersect the guiding direction of the game ball in the outlet portion 105 of the guide passage 103. The portion 511 and the second plate portion 521 formed so as to face the inner rail 101 from the game area PE side are connected so as to be substantially L-shaped with the connecting portion 531 as a boundary.

  As shown in FIG. 21 and FIGS. 22B and 22C, the first plate portion 511 is inclined with respect to the rear of the guide so that the plate surface faces the side in the guide direction. Specifically, the end of the first plate portion 511 opposite to the connection portion 531 is formed so as to be inclined with respect to the guide direction so that the end of the first plate portion 511 is on the back side of the guide portion 531. Yes. Further, as shown in FIGS. 22A and 22C, the first plate portion 511 is inclined so as to incline to the back side in the guiding direction with respect to the front surface of the game board 80 (plate body 80a).

  As shown in FIGS. 22A and 22B, the thread member is pushed and pulled in the state where the thread member is in contact with the end 512 opposite to the connection portion 531 in the first plate portion 511. Thereby, the 1st blade part 513 which can cut | disconnect the said thread-like member is formed. The first blade portion 513 is inclined obliquely from the back of the gaming machine toward the front of the gaming machine. More specifically, it is inclined so as to approach the center side of the game board 80 as it moves away from the front surface of the game board 80.

  Further, as shown in FIGS. 22 (a) and 22 (c), the thread-like member is in a state in which the above-described thread-like member has also hit the tip portion 514 (portion facing the front of the gaming machine) of the first plate portion 511. A second blade portion 515 capable of cutting the thread-like member by being pushed and pulled is formed. The second blade portion 515 is inclined so that the amount of standing from the front surface of the game board 80 decreases as the end portion 512 approaches the connecting portion 531.

  The above fraudulent act using the illegal ball to which the thread-like member is fixed by the blade portions 513 and 515 described in detail above is made difficult. Hereinafter, the configuration for realizing the cutting of the thread-like member will be described in more detail with reference to FIG. 22 (d) and FIG. 22D is a partial cross-sectional view taken along the line GG in FIG. 21, and FIG. 23 is a schematic view showing the relationship between the guide passage 103, the thread-like member, and the cutting portion.

  As shown in FIG. 23, the width dimension of the guide passage 103 is set larger than the diameter dimension of the game ball, and a certain margin is given. However, since the game ball flowing into the game area PE moves along the outer rail 102 when passing through the guide passage 103, the game ball passing path is outside for a normal game. It becomes a predetermined region PR along the rail 102. Here, the first plate portion 511 included in the conductive member 500 is formed such that the end portion 512 thereof is located outside the extension of the predetermined region PR, and the game ball passing through the predetermined region PR Preventing movement is avoided.

  Note that the second plate portion 521 is disposed at a position facing the inner rail 101 from the game area PE side, and of course is not located even on the extension of the guide passage 103. For this reason, the presence of the second plate portion 521 does not prevent the inflow of game balls to the game area PE.

  Referring to FIG. 23, supplementary explanation will be given for the reverse prevention member 106. In the initial state, the movable piece 108 of the reverse prevention member 106 is disposed at a position overlapping the extension region of the predetermined region PR, and the game toward the game region PE. By being pushed by the sphere, it is displaced to a position that does not overlap with the extension region. The movable piece 108 is urged toward the overlapping position, and after the game ball has passed, it returns to the initial state by the urging force.

  In a state where the illegal ball flows into the game area PE, the thread-like member is present at a position along the inner rail 101 with the contact portion of the reversion preventing member 106 with the movable piece 108 as the center. Here, since the first plate portion 511 is disposed so as to interfere with a region through which the thread-like member passes in a state where tension is applied to the thread-like member, the above-described cutting function effectively operates. Configuration is realized.

  Referring to FIG. 22 (d), a supplementary explanation will be given regarding the amount of standing of the first plate portion 511 from the front surface of the game board 80. The amount of standing is set to be larger than the radius dimension of the game ball. For this reason, inconveniences such as interference between the thread-like member and the first plate portion 511 are less likely to occur. Further, the gap between the front surface of the game board 80 and the glass panel 23 is set to be larger than the diameter dimension of the game ball, and the forward and backward movement of the game ball is allowed to some extent. However, such back-and-forth movement is allowed, but the actual collision of the game ball with the glass panel 23 may cause a hitting sound or damage the glass panel 23. Various measures are taken so that the game ball moves along the front surface of the game board 80. In consideration of such circumstances, the maximum value of the standing amount is the maximum protruding portion (when the gaming ball 80 is lifted from the front of the gaming board 80, i.e., the first blade portion 513 and It is set so as to be able to exceed the boundary portion with the second blade portion 515. Note that the configuration for moving the game ball along the front surface of the game board 80 is well-known and commonly used, and thus the description thereof is omitted.

  As shown in FIG. 23, in a state in which the illegal sphere is hung on the reversion preventing member 106 by the thread-like member, the movable piece 108 moves from the initial position to the operating position due to the weight of the illegal sphere, and is maintained in that state. Here, when the player tries to adjust the position of the illegal ball by pulling the thread-like member, the thread-like member bites into the first blade portion 513. Here, the first blade portion 513 is not perpendicular to the moving direction of the thread-like member accompanying the pulling operation, but is inclined obliquely so as to approach the moving direction. For this reason, the thread-like member is urged to move forward along the first blade portion 513 by the pulling operation. At this time, the cutting function of the first blade portion 513 is preferably exhibited by moving the thread-like member while maintaining the portion of the thread-like member that is in contact with the first blade portion 513 as much as possible.

  When the thread-like member continues to move along the inclination of the first blade portion 513, it moves over the maximum protrusion and moves to the second blade portion 515. As described above, the game ball is applied with a force to return to the front side of the game board 80, so that the state in which the game blade is pressed by the second blade portion 515 is maintained, and the cutting function by the second blade portion 515 is performed well. The Rukoto.

  Here, when a fraudulent person pulls the thread-like member strongly, a load generated on the first plate part 511 increases, and there is a concern that the first plate part 511 may be deformed when the thread-like member is cut. . In this regard, as shown in the present embodiment, the load generated in the first plate portion 511 is caused by guiding the thread-like member so as to approach the connecting portion 531 with the second plate portion 521, so that the second plate portion 521 has a load. The first plate portion 511 can be protected.

  Further, since the through holes 80c formed in the game board 80 are configured to engage with the respective plate portions 511 and 521, the load generated in the first plate portion 511 may be distributed to the game board 80 side. It is possible. With the above configuration, the deformation of the first plate portion 511 is suppressed, and the function of cutting the thread-like member is protected.

  Regarding the cutting structure of the thread-like member in the present embodiment, since the blade parts 513 and 515 which are the main parts thereof face the front side of the gaming machine, the thread-like member is fixed to the person trying to execute fraud. It is possible to give an impression that it is difficult to cheat using a ball, and to increase the deterrence of cheating. In particular, even if the thread-like member is successfully cut, if the illegal ball with the thread-like member is returned to the island facility, there is a possibility that the thread-like member may be entangled with some object and cause a failure or the like. Therefore, the improvement of the deterrence mentioned above has technical significance.

  Unlike the conductive member 400 shown in the third embodiment, the conductive member 500 in the present embodiment described in detail above cannot be prevented from being visually degraded due to being visible. However, considering that the conductive member 500, which is premised to be a metal member, can improve the crime prevention function while efficiently exhibiting a grounding function, it is good to make the conductive member 500 actively appear. It is advantageous in producing an effect that can eliminate the decrease.

<Fifth embodiment>
In each of the above embodiments, various crime prevention structures against fraud using a game ball (illegal ball) to which a thread-like member is fixed have been adopted. However, in this embodiment, the structure according to this crime prevention structure is characteristic. It has become a thing. Specifically, in each of the above embodiments, it is not restricted that the illegal ball reaches the game area PE, but the position adjustment is impossible or difficult when the game ball reaches the game area PE. Although the crime prevention function was improved by doing so, in the present embodiment, it is made for the purpose of making it difficult or impossible to reach the game area PE of the illegal ball, and such a premise is assumed. There is a difference in the crime prevention structure based on the difference in issues. Hereinafter, with reference to FIG.24 and FIG.25, the premise structure of the crime prevention structure (crime prevention structure with respect to an illegal ball) in this Embodiment is demonstrated, and the principal part of a crime prevention structure is demonstrated after that. FIG. 24 is a front view showing a game ball launching mechanism in the fifth embodiment, FIG. 25 (a) is a schematic diagram showing the internal structure of the ball feeding device, and FIG. 25 (b) shows a passage structure in the ball feeding device. It is a side view.

  As shown in FIG. 24, the game ball launching mechanism 110X includes a ball feeding device 113X that supplies game balls one by one to the launch rail 112 based on the operation of the game ball launch handle 41. The ball feeding device 113X is disposed above the lower end (upstream end) of the launch rail 112, and the game ball that flows out of the ball feed device 113X (the game ball supplied to the launch rail 112) is It flows down along the firing rail 112, and further falling down is prevented by hitting a stopper member 115 arranged away from the firing rail 112 so as to secure an operation area of the solenoid 111 above the lower end of the firing rail 112. It becomes a state. The position where the flow is prevented by the stopper member 115 in this way is the game ball launch standby position (see the two-dot chain line in FIG. 24).

  Here, with reference to FIG. 25, the structure of the ball feeding device 113X will be supplementarily described. The ball feeding device 113X is made of a synthetic resin material, and a ball feeding passage 601X capable of storing a plurality of game balls is formed therein.

  As shown in FIG. 25A, the ball feeding passage 601X includes an upstream passage portion 602X having an inlet portion 604X into which game balls sequentially flow from the upper plate 33 provided in the front door frame 14, and a launch rail. And a downstream passage portion 603X having an outlet portion 605X opened to the 112 side. The upstream-side passage portion 602X and the downstream-side passage portion 603X are arranged side by side so that the former is in front of the gaming machine and the latter is in the rear of the gaming machine, and is continuous through a connecting passage portion extending in the front-rear direction. Each of these passage portions is gently inclined downward, and the game ball that has flowed into the ball feeding passage 601X from the entrance portion 604X is caused by its own weight and the pressure from the subsequent game balls, and the entrance portion 604X → the upstream passage portion 602X → the downstream side. It moves through the passage portion 603X and is discharged to the firing rail 112 through the exit portion 605X.

  Note that the ball feeding passage 601X is set to be slightly larger than the diameter of the game ball so that a plurality of game balls cannot pass through the same passage width (vertical width and horizontal width) at the same time. For this reason, in a state where a plurality of game balls are stored in the ball feeding passage 601X, a single row of game balls is formed.

  As described above, in the configuration in which the game ball is moved using the ball pressure of the subsequent game ball, the supply function of the game ball may not work well due to the excessive ball pressure. Therefore, the ball feeding passage 601X in the present embodiment is formed by folding the upstream passage portion 602X and the downstream passage portion 603X around the intermediate passage portion, so that the ball pressure in the ball feeding passage 601X is reduced. In order to reduce the pressure, the ball pressure from the subsequent game ball is devised so as not to act strongly on the ball feeding operation.

  The passage structure will be described in more detail. The upstream passage portion 602X is located in front of the firing rail 112, and the downstream passage portion 603X is located immediately above the firing rail 112. Further, when comparing the upstream-side passage portion 602X and the downstream-side passage portion 603X, the passage length of the downstream-side passage portion 603X is set shorter than the passage length of the upstream-side passage portion 602X, as viewed from above. In this case, the overlap between the launch rail 112 and the downstream passage portion 603X is not increased. As a result, a gap allowing the movement of a game ball, which will be described later, is secured above the firing rail 112.

  As shown in FIG. 25 (b), the upstream-side passage portion 602X and the downstream-side passage portion 603X are formed so as to overlap each other when viewed from the front of the gaming machine, and between the inlet / outlet in the ball feeding passage 601X. It is devised so that the height difference becomes as small as possible.

  The exit portion 605X of the ball feeding device 113X is provided with a movable shutter 620X that can be switched between a permissive state that allows the game ball to flow out of the ball feed passage 601X and a blocking state that prevents the outflow of the game ball. ing. The shutter 620 </ b> X is connected to a drive unit (not shown), and a drive signal is output from the power supply / emission control device 243 to the drive unit, thereby switching from the blocking state to the permissible state. Note that the shutter 620X is normally energized so as to be in a blocking state, and is allowed against the energizing force only during a period in which the drive signal is output.

  Here, the relationship between the shutter 620X and the outlet portion 605X will be described with reference to FIG. FIG. 26A is a perspective view showing the outlet portion 605X of the ball feeding device 113X, and FIG. 26B is a schematic diagram showing the relationship between the ball feeding path 601X and the shutter 620X.

  As shown in FIG. 26A, the shutter 620X includes a plate-like cover portion 621X that covers the outlet portion 605X, and an arm portion 622X that extends from the front and rear ends of the cover portion 621X to the upstream side of the passage. . The arm part 622X is pivotally supported by protrusions formed on the side wall part 613X constituting the downstream side passage part 603X, and is rotatable about these protrusions. When power is transmitted from the drive unit to the shutter 620X, the shutter 620X rotates about the protrusion, and the switching from the blocking state to the permission state described above is realized. In such a state, almost the entire cover portion of the shutter 620X is located below the bottom plate portion 612X, and the outlet portion 605X is completely opened.

  Further, when the transmission of power is stopped after entering the allowable state, the shutter 620X is rotated in the reverse direction by the urging force, and switching from the above-described allowable state to the blocking state is realized. As a result, the outlet portion 605X is again covered with the cover portion 621X (for example, the outlet portion 605X is in a closed state), and the outflow of game balls from the outlet portion is prevented.

  Here, as shown in FIG. 26B, the distance between the top plate portion 611X and the bottom plate portion 612X of the downstream passage portion 603X becomes smaller as it goes downstream. Specifically, the inclination angle of the top plate portion 611X is set larger than the inclination angle of the bottom plate portion 612X, and the movement of the game ball in the vertical direction is restricted in the vicinity of the outlet portion 605X.

  Due to the inclination of the top plate portion 611X, a step is generated between the upper end edge of the side wall portion 613X and the top surface of the top plate portion 611X. An opening flange that rises upward and connects both side wall portions 613X is formed in a portion of the top plate portion 611X that constitutes the outlet portion 605X so as to compensate for this step. This opening flange constitutes a facing portion 615X that faces the covering portion 621X with a slight gap under the situation where the shutter 620X is in a blocking state.

  Hereinafter, with reference to FIG. 27, the flow of supply and launch of game balls by the ball feeding device 113X will be described. FIG. 27 is a schematic view showing a state of launching a game ball, and the game ball launch mechanism 110X (the ball feeding device 113X and the solenoid 111) is based on the launch operation by the player from FIG. 27 (a) to FIG. 27 (b). The operation is performed in the order of FIG. 27 (c) → FIG. 27 (a). In FIG. 27, for the sake of convenience of explanation, the ball feeding passage 601 is partially shown in plan view, but the actual structure is as shown in FIG.

  As shown in FIG. 27 (a), when a game ball is placed at the launch standby position, the solenoid is operated based on the game ball launch handle 41 (see FIG. 1 etc.) being operated by the player. The drive signal is output to 111 and the solenoid 111 is exemplified, so that the output shaft passes between the stopper member 115 and the launch rail 112 and hits the game ball waiting at the launch standby position. As a result, the game ball moves on the launch rail 112 and moves from the launch rail 112 to the guide rail 100 (specifically, the entrance portion 104 of the guide rail 100).

  Immediately after the game ball is fired, output of the drive signal to the solenoid 111 stops and output of the drive signal to the drive unit for the shutter 620X is started. Thereby, as shown in FIG. 27B, the shutter 620X is switched from the blocking state to the allowable state. When the shutter 620X is switched to the allowable state, the outlet portion 605X of the ball feeding path 601X is opened, and the game ball flows out from the ball feeding path 601X (see FIG. 27 (b) → FIG. 27 (c)).

  Since the exit portion 605X is located slightly downstream of the firing rail 112 from the firing standby position, the game ball that has dropped from the exit portion 605X to the firing rail 112 is caused by its own weight along the inclination of the firing rail 112. It moves upstream (downward) and hits the stopper member 115. Thereby, it will be in the state by which the said game ball was arrange | positioned at the discharge standby position, ie, a launch preparation state.

  Here, as shown in FIG. 27 (c) → FIG. 27 (a), the shutter 620X enters the blocking state based on the urging force at a timing immediately after one game ball flows out from the outlet portion 605X. Return. For this reason, a situation in which subsequent game balls continuously flow out to the exit portion 605X and a plurality of game balls wait on the launch rail 112 does not occur.

  According to the operation of the ball feeding device 113X (specifically, the shutter 620X) and the solenoid 111 described in detail above, it is possible to prevent the illegal ball to which the thread-like member is fixed from being launched. Hereinafter, a specific example of the emission restriction will be described with reference to FIG. FIG. 28 is a schematic diagram illustrating the state of illegal ball launch control. In FIG. 28, as in FIG. 27, for convenience of explanation, the ball feeding passage 601 is partially shown in plan view, but the actual structure is as shown in FIG.

  As shown in FIG. 28 (a), the central portion of the game ball arranged at the firing standby position is located on the extension of the output shaft of the solenoid 111, and the firing rail 112 also has an operation direction of the output shaft. They are arranged in parallel. According to such a configuration, it is possible to efficiently transmit the force from the output shaft to the game ball, and the game ball pushed by the output shaft can move smoothly along the launch rail 112.

  Here, when an illegal ball is sent to the ball feeder 113X through the upper plate 33, the illegal ball is sequentially moved to the downstream side by continuing the operation of launching the game ball, and finally the exit portion. 605X is reached (see FIG. 28A).

  Here, when the game ball is fired and the shutter 620X is switched from the blocked state to the permitted state, the illegal ball flows out from the outlet portion 605X as shown in FIG. At this time, a part of the thread-like member also flows out from the exit portion 605X to the firing rail 112 side.

  Here, as shown in FIG. 28 (b) → FIG. 28 (c), when the shutter 620X is switched from the blocked state to the allowed state, the thread-like member is sandwiched between the shutter 620X (specifically, the cover portion 621X) and the facing portion 615X. It is. Even if the solenoid 111 operates to fire the illegal ball in this state, the illegal ball does not move well because the thread-like member is held between the shutter 620X and the opposed portion 615X. That is, the presence of the thread-like member obstructs the launch of the illegal sphere, and the illegal sphere is prevented from jumping out from the launch rail 112.

  In the present embodiment, when the shutter 620X is switched from the permitting state to the blocking state, the cover 621X (see FIG. 26) of the shutter 620X remains facing the facing portion 615X before the operation of the shutter 620X is completed. It moves so that the gap between the two becomes gradually smaller. By adopting such a configuration, even when a certain amount of tension is generated in the thread-like member, it is possible to suppress the presence of the thread-like member from being a factor that hinders the operation of the shutter 620X.

  Here, in the present embodiment, the part of the thread-like member is bent into a crank shape by the shutter 620X and the facing part 615X, and further the movement of the thread-like member is performed by setting the clamping position to a position off the firing track. It is possible to increase the drag that hinders this. However, there is a concern that when such a drag force becomes excessively large, the load applied to the shutter 620X and the facing portion 615X increases, which hinders the closing function of the outlet portion 605X. Therefore, in the present embodiment, various measures are taken to avoid such inconvenience.

  First, as described above, the shutter 620X is of a rotary type and is not fixed to the blocking state but is maintained in the blocking state by the urging force of the urging means. For this reason, when an excessively large force is applied to the shutter 620X at the time of launching the illegal ball, the shutter 620X rotates against the urging force to the permissible state side, so that the load can be released. It has become. Even in this case, at least the movement of the filamentous member is hindered, so that the illegal ball does not jump out of the firing rail 112, and the firing regulation function is secured.

  Further, as shown in FIG. 28 (b) → FIG. 28 (c), when the shutter 620X switches from the allowable state to the blocking state, the upper end portion of the shutter 620X (cover portion 621X) is displaced upward. Here, the biasing force described above is set to be sufficiently larger than the weight of the game ball, and the ball feeding passage 601 meanders and there are a plurality of succeeding balls. It is pushed upward, and the illegal sphere is prevented from reaching the launch standby position. As a result, when the output shaft of the solenoid 111 is operated, the solenoid 111 and the game ball are prevented from hitting well, and the output can be prevented from being transmitted to the 100% illegal ball.

  Furthermore, as shown in FIG. 28C, the illegal sphere is lifted from the launch rail 112, so that the illegal sphere is shifted upward with respect to the operation trajectory of the output shaft described above. As a result, as described above, the output of the solenoid 111 is distributed in the rail direction and the upward direction of the firing rail 112, and energy sufficient to reach the game area PE is not transmitted to the illegal ball.

  As described above, when the movement of the illegal ball is restricted, there is a possibility that the game ball may move so as to rotate upward or float around the pinched position of the thread-like member. (Including the portion where 113X is arranged) has a space that allows the movement of the game ball, and the above-described movement of the game ball is allowed (see FIG. 28D).

  As described in detail above, even if the launch of the illegal sphere is restricted by preventing the movement of the filamentous portion, the force transmitted from the solenoid to the illegal sphere is well distributed, so the game ball launch mechanism 110X including the shutter 620X is damaged. It is possible to avoid inconvenience such as deformation and deformation.

  In addition, in the state where the launch of illegal spheres is restricted, it is assumed that the fraudster attempts to collect the illegal spheres in order to conceal the evidence of fraud. As this method, a method of pulling the thread-like member by hand and a method of continuously returning the illegal ball to the lower plate 34 by continuing the operation of launching the game ball are assumed. It is difficult to collect illegal balls.

  First, in order to pull the thread-like member by hand, it is necessary to release the shutter 620X to cancel the holding state of the thread-like member. However, even if the shooting operation is continued and the shutter 620X is released, the subsequent game balls The ball pressure makes it difficult to pull back the illegal ball. Certainly, it is possible to reduce the number of succeeding game balls by using the ball removing mechanism provided on the upper plate 33. However, such an action is easy to draw the attention of the surroundings. Even if the number of succeeding balls is reduced, at least the game balls remain in the ball feeding path 601X of the ball feeding device 113X. Thereby, the concealing action becomes difficult.

  Next, when the illegal ball is left as it is and the game ball is fired, the succeeding game ball is supplied to the launch rail 112 each time the launch operation is performed. It takes a considerable amount of time to guide the ball to the collection passage. In particular, regarding the positional relationship between the game balls, the subsequent game balls are likely to be located downstream (the front side in the firing direction), so that the subsequent game balls get in the way and become detached from the launch rail 112. Is assumed to be difficult.

  For the reasons described above, it is difficult to collect illegal balls, and the act becomes unnatural unlike ordinary games, so that the deterrence of fraud can be improved.

  Note that the shutter 620X in the present embodiment is a rotary type, but may be a slide type. However, considering the load generated by the illegal sphere launch operation and the security of the state switching function, at least when the configuration corresponding to the shutter operates, the gap with the facing portion 615X gradually increases at the final stage. It is preferable to devise so as to be small.

<Other embodiments>
In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows. Incidentally, the configurations of the following different modes may be applied individually to the configurations of the above embodiments, or may be applied in combination with each other.

  (1) In the first embodiment, the arm 302 of the rotator 303 is set in a standby position as a “predetermined position” by the magnetic force of the magnets 97 and 321. However, the arm 302 is set in a predetermined position. If possible, the means is not limited to magnetic force.

  For example, by tilting the central axis to the left and right, it is possible to make the arm 302 stand by at a predetermined position using the weight of the arm 302.

  In addition, a variable stopper means that can be switched between a blocking state for preventing the movement of the arm 302 from a predetermined position and an allowable state for allowing the movement from the predetermined position is provided, and the power of the stopper means is blocked / allowed. You may implement | achieve the standby state and rotation state in a predetermined position by switching to a state. In this case, as a driving means for driving the stopper means, a driving motor or the like may be separately received, or a link mechanism for operating the stopper means in linkage with the movement of the rotating body may be provided.

  Furthermore, it is possible to realize the function of waiting at a predetermined position and the function of stopping the rotation with different configurations. Specifically, before the arm 302 reaches the predetermined position, the arm 302 moves to a blocking position that prevents the rotating body 303 from rotating beyond the predetermined position, and after the arm 302 reaches the predetermined position, the arm 302 moves from the blocking position to the arm. Stopper means for moving to a permissible position allowing movement of 302 may be provided. In this case, after temporarily stopping at the blocking position, the magnetic force of the magnets 97, 321, etc. may be used to wait at a predetermined position.

  (2) In the first embodiment, the contact surface 322 is formed so that the rotating body 303 rotates by hitting a game ball moving downstream along the guide rail 100. However, the present invention is not limited to this. Instead, when the game ball moves upstream along the guide rail 100 (reversely moves back), the contact surface 322 is arranged on the upstream side of the guide rail 100 so that the rotating body 303 rotates by hitting the game ball. It is also possible to incline both downstream and downstream.

  (3) In the first embodiment and the second embodiment, the arm 302 is formed at an intermediate position of the shaft body 301. However, the arm 302 has a configuration corresponding to at least the shaft body 301 and the arm 302. The arrangement of the arm 302 is arbitrary. For example, it is possible to form an arm at the end of the shaft.

  Note that the shaft body 301 may be provided with an aggregating portion (for example, a concave portion or a groove portion) that aggregates the wound thread-like member at a predetermined position. According to such a configuration, each time the thread-like member is wound, the wound thread-like members are easily entangled by being stacked on the previously wound thread-like member. Incidentally, the function can be suitably exhibited by providing a guiding portion for guiding the filamentous member to the aggregation portion.

  (4) In the first embodiment and the second embodiment, the shaft body 301 and the arm 302 rotate integrally by attaching the shaft body 301 so as to be rotatable. However, the shaft body 301 may be fixed, and the arm 302 may be rotatably attached to the fixed shaft body 301. For example, the shaft body is formed in a stepped cylindrical shape with a recessed central portion, and a ring portion that engages with the recessed portion is formed in the arm, so that the arm rotates alone (the arm relative to the shaft body 301). (Configuration in which 302 is relatively displaced).

  However, when the thread-like member is wound up, the tension tends to be generated at the base portion of the arm through the thread-like member, and as a result, the rotation function of the arm may be lowered. In view of such circumstances, it is preferable that the shaft body and the arm rotate integrally as shown in the above embodiment.

  (5) In the first embodiment and the second embodiment, the winding mechanism 300 is disposed at a position where it can be seen from the front of the gaming machine, thereby improving deterrence against fraud using a fraudulent ball. However, the arrangement of the winding mechanism 300 is not limited to this. Preferably, the position is visible from the front of the gaming machine as shown in the above embodiment, but may be a position where the visual recognition is impossible or difficult from the front of the gaming machine. For example, it may be arranged on the outer rail 102 side (behind the frame body 20 of the front door frame 14) or on the back side of the game board 80.

  Moreover, it is not always necessary to arrange them corresponding to the guide rails, and the application target is arbitrary as long as it is a passage (passage partitioned by the wall surface portion) through which the game ball passes. For example, the present invention can be applied to various guide passages provided in the ball feeding device 113X and the upper plate 33 shown in the fifth embodiment, and further to a discharge passage for discharging game balls that have entered the entrance portion. It is.

  (6) In the first embodiment and the second embodiment described above, the threaded member is wound up at the timing after the game ball flows into the game area PE from the guide passage 103. It is also possible to adopt a configuration in which the thread-like member is wound up at a timing before flowing out from the guide passage 103.

  However, in such a configuration, even if a subsequent game ball is fired, its movement is hindered by the illegal ball, and it is not possible to expect continuous launch of game balls. For this reason, it is assumed that the number of turns of the thread-like member is also reduced. Therefore, in order to restrict the movement of the filamentous member by the winding mechanism 300, it is preferable that the winding is completed after the game ball flows into the game area PE as shown in the above embodiment.

  (7) In the first embodiment and the second embodiment, the arm 302 is formed in a rod shape. For example, a hook-shaped portion that protrudes forward in the rotation direction is formed on the tip portion of the arm 302 or the like. It is also possible. According to such a configuration, it is possible to prevent the thread-like member from slipping from the tip of the arm 302 when winding the thread-like member.

  In order to prevent the thread-like member from slipping, it is also effective to form a plurality of irregularities (that is, hooks) on the guiding inclined surface 323 so as to be aligned in the longitudinal direction of the guiding inclined surface 323. However, in such a configuration, the function of guiding the thread-like member toward the center of rotation is not exhibited well, and it is difficult to suppress a decrease in rotational torque. Therefore, it is preferable to adopt the above modification so that the function of guiding to the rotation center side and the function of preventing the thread-like member from slipping through can coexist.

  (8) In the first embodiment and the second embodiment described above, the guide direction (tangential direction of the guide rail 100) at the winding position in the guide passage 103 and the central axis direction of the rotating body 303 are the same direction. However, the directions do not necessarily have to coincide with each other, and the central axis direction may be inclined with respect to the guiding direction.

  (9) In the first embodiment and the second embodiment described above, the rotation direction of the rotating body 303 is restricted to the direction 1 by the stopper piece 306 and the gear portion 313, but this configuration is omitted. The rotating body 303 may be allowed to rotate in both forward and reverse directions. If at least the thread-like member can be wound, it is possible to prevent the illegal ball from being moved by operating the thread-like member.

  (10) In the second embodiment, the take-up mechanism 300 is rotated based on the game ball launch operation. However, if the take-up mechanism 300 operates at least based on the play of the game ball. For example, a passage detection sensor that detects the passage of the game ball may be provided in a section from the launch position of the game ball to the winding position, and the winding mechanism 300 may be operated based on information from the passage detection sensor.

  (11) In the second embodiment, when the load generated along with the winding of the thread-like member exceeds a threshold value, further winding is performed on condition that the arm 302 has returned to the standby position. However, if the load exceeds the threshold value, the winding of the filamentous member by the winding mechanism 300 may be continued until a predetermined release operation is performed.

  In addition, the winding mode may be changed when the load exceeds the threshold value, and the rotating body 303 may be rotated a plurality of times instead of rotating once based on each game ball being fired.

  (12) In the third embodiment, by attaching the game board 80 to the inner frame base body 50, an automatic connection path that is grounded by contact between the conductive member 400 and the vertical frame member 55, Although it is configured to suppress charging of the guide rail 100 and the game ball by two systems of the wiring 401 connected to the member 400 → the center frame 95 → the wiring not shown → the manual connection path using the horizontal frame member 57, It is not necessary to use two systems of antistatic paths, and it is possible to adopt a configuration including only one of them. However, the necessity of performing a separate ground connection work (connection work between the wiring and the lateral frame member 57) every time the game board 80 is attached / detached can be a factor in reducing workability. Therefore, it is preferable to provide an automatic connection path.

  (13) In the third embodiment, the ground of the guide rail 100 is limited to one place, but there may be a plurality of places to be grounded. The antistatic function can be further improved by grounding at a plurality of locations.

  In this case, a portion corresponding to the “main body portion” is an arc-shaped rail portion extending along the inner rail 101 or the outer rail 102, and the rail portion is disposed behind one of the inner rail 101 or the outer rail 102 and the rail. Improve the antistatic function while preventing the main body part from deteriorating in appearance by providing an extended part that extends from the part toward the other rail 101, 102 and connecting the legs that extend from both rails Can contribute.

  (14) In the fourth embodiment, the crime prevention function is improved by cutting the thread-like member using the conductive member 500 for the irregular sphere to which the thread-like member is attached. However, in such a configuration, after the thread-like member is cut, the illegal ball with the same thread-like member is discharged from the gaming machine and returned to the island facility, so that the ball is distributed by a game ball distribution mechanism or the like. It is assumed that problems such as clogging are likely to occur. That is, it is not preferable for the game hall to leave the illegal ball attached to the thread-like member as it is.

  Therefore, a movable lid is provided at the game ball outlet of the gaming machine, and a position detection sensor for the movable piece 108 of the reversal prevention member 106 is provided. When it is determined that the ball stays for a period of time, it is determined that the ball is pressed by the thread member, and the lid is closed to make it impossible to discharge the game ball from the gaming machine. Thereby, since the discharge of the game ball is impossible at the time when the above-described cutting of the thread-like member is executed, it is possible to prevent the illegal ball with the thread-like member from returning to the island facility after cutting. Thereby, it is possible to achieve both improvement of the crime prevention function and avoidance of the above inconvenience.

  (15) In the fourth embodiment, the blade portions 513 and 515 as “cutting portions” formed in the conductive member 500 face the front side of the gaming machine. Although this configuration is excellent in informing the fraudsters of the existence of the blade portions 513 and 515 and suppressing fraud, the front door frame 14 is opened when performing maintenance work such as cleaning of the game board 80. In this case, since the blade parts 513 and 515 are exposed to the front side of the gaming machine, it is necessary to pay attention not to touch these blade parts 513 and 515 during the work, which may hinder the improvement of workability. There is.

  Therefore, a movable cover that can be displaced is provided at a position that covers the blade portions 513 and 515 and a position that does not cover the blade portion, and when the front door frame 14 is opened, the cover is moved from the covered position to the uncovered position. When the front door frame 14 is displaced, the cover may be displaced from the uncovered position to the covered position. Thereby, it becomes possible to achieve both the effect of improving the deterrence and avoiding the deterioration of workability.

  (16) In the fourth embodiment, the blade portions 513 and 515 are provided as the “cutting portions”. However, the thread-like member can be cut based on the displacement of the thread-like member (a pulling operation by an unauthorized person). For example, the “cutting portion” does not necessarily have to be a blade portion. For example, a file having fine irregularities may be used instead of the blade portion.

  (17) In the fourth embodiment, the cutting function of the blade portion 513 is improved by configuring the blade portion 513 to be inclined downward toward the front side of the gaming machine. It is not limited. It is also possible to adopt a configuration in which the blade portion 513 is inclined downward toward the rear of the gaming machine.

  However, in order to improve the deterrence of fraud using illegal balls by making the blade visible from the front side of the gaming machine, the above-mentioned modification improves deterrence by reducing the visibility of the blade. There is a possibility that the effect is not exhibited well. Therefore, it is preferable that the blade portion 513 is inclined downward toward the front side of the gaming machine as shown in the fourth embodiment.

  (18) In the fifth embodiment, the crime prevention function is improved by preventing the movement of the thread-like member and making it difficult to launch the illegal sphere. However, the movement of the thread-like member is prevented and the game area PE is prevented from moving. What is necessary is just to be able to prevent the arrival of illegal balls. In consideration of such a function, it is not necessary to provide a gap between the cover portion 621X of the shutter 620X and the facing portion 615X. For example, the facing portion and the shutter can be brought into contact with each other.

  Further, the gap may be arbitrarily adjusted as long as it can generate a drag that can prevent the illegal ball from reaching the game area PE.

  (19) In the fifth embodiment, the facing portion 615X and the shutter 620X are arranged above and below the outlet portion 605X of the ball feeding path 601X. However, regarding the arrangement of these components, at least the outlet portion 605X is arranged. What is necessary is just to be arrange | positioned so that it may become the both sides which pinched | interposed.

  For example, the upper and lower configurations can be reversed. However, it is necessary that the exit portion 605X of the ball feeding path 601X exists above the standby position of the game ball on the launch rail 112, and further, when the illegal ball moves irregularly with the launch. In consideration of securing a moving space, the positional relationship between the shutter 620X and the facing portion 615X is preferably the configuration shown in the fifth embodiment.

  (20) In the fifth embodiment, the shutter 620X is disposed on the downstream side of the facing portion 615X in the game ball guiding direction by the ball feeding path 601X. However, it is also possible to reverse the arrangement of these two configurations. It is. However, in this case, it is preferable that the elastic deformation toward the downstream side of the facing portion is allowed and the impact generated in the facing portion is released when the illegal ball is launched.

  In addition, the relationship between the shutter and the facing portion may be any as long as it is opposed upstream / downstream. For example, the front end portion of the shutter may be fitted in the recess. In this case, two surfaces facing the shutter from upstream and downstream in the concave portion form a facing portion.

  (21) In the fifth embodiment, the shutter 620X is a rotary type. However, the shutter 620X is not limited to this and may be a slide type. However, it is not preferable that the movement of the shutter is hindered by the thread-like member when the thread-like member is sandwiched between the facing portion 615X. Therefore, in order to pinch the thread-like member well, when the shutter is in the blocking state, it is preferable to make a movement toward the facing portion 615X (a movement in which the gap gradually decreases).

  (22) In the fifth embodiment, the opposing portion 615X and the shutter 320X are employed as a hold mechanism for restricting the movement of the thread-like member attached to the illegal ball, and such a configuration is disposed at the exit portion of the ball feeding path 601. However, the position where the hold mechanism is arranged is arbitrary. For example, the hold mechanism can be arranged in the entrance portion 604X of the ball feeding path 601X. However, when it is perceived that a fraudulent person is difficult to launch a fraudulent sphere, it is assumed that the fraudulent sphere is attempted to be collected by pulling the filamentous member in order to conceal the evidence of the fraudulent act. In making such a concealing action difficult, other game balls existing upstream from the position where the hold mechanism is arranged can function as an obstacle. Therefore, when the hold mechanism is arranged, it is preferable that the game ball is in a standby state on the upstream side. In particular, when an open / close-type return port for removing a ball is provided on an upper plate or the like, even if a subsequent game ball is removed from the return port, at least one game ball is held by the hold mechanism. It is advisable to arrange the hold mechanism so that it remains immediately upstream.

  (23) Other types of pachinko machines different from the above-described embodiments, such as pachinko machines that release a predetermined number of times when a game ball enters a specific area of a special device, or games in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a ball enters, a pachinko machine equipped with another accessory, an arrangement ball machine, a sparrow ball, and the like.

<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.

<Feature A group>
The following feature group A is “Some game machines such as pachinko machines have a game board with a game area formed on the front surface. A game ball launched based on a player's launch operation is a game. By entering (winning) a pitching portion provided in the area, the winning is detected by a detection sensor, and the detected information is transmitted to the control device, and the player based on this information in the control device. (For example, refer to JP-A-2003-190511) A game machine of a type in which a privilege is given in response to a winning in such a winning part. In this case, there may be a difference in whether or not the game can be advantageously advanced depending on the winning occurrence rate (winning frequency) of the winning portion. In recent years, many games have been held. Various fraudulent acts have been reported on gaming machines aimed at enjoying the benefits of, for example, a game ball with a tip of a thread-like member such as a fishing line or a piano wire fixed to the game area, and There is a fraudulent act of manipulating a game ball with a member (so-called thread hanging goto), which can be used to, for example, guide a subsequent game ball to the entrance or By reciprocating the game ball with the thread-like member fixed to the detection area of the detection sensor provided in the ball part, it is misunderstood as if a lot of game balls have won, and the privilege is illegally acquired Such fraudulent acts are less conspicuous than fraudulent acts such as fraudulent fraud, and it is difficult for the hall manager to detect fraudulent acts visually. In view of the background and issues such as “there are no effective measures against such fraud, and there is still room for improvement in the crime prevention function of gaming machines in order to prevent such fraud.” It was made.

Feature A1. A ball passage (guide passage 103) through which game balls pass,
Opening portions (slits 80b and 101b) provided in passage wall portions (inner rail 101 and plate body 80a of game board 80) defining the ball passage and penetrating into and out of the ball passage;
A shaft body (shaft body 301) provided outside the spherical passage;
By rotating around the shaft body, it is displaced so as to cross the sphere passage area of the spherical passage to a position where it protrudes into the spherical passage through the opening and a position where the projection into the spherical passage is avoided. And a movable body (arm 302).

  In a gaming machine such as a pachinko machine, for example, a game ball (hereinafter also referred to as an illegal ball) to which a tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area, and the illegal ball is operated by operating the yarn-like member. An illegal act of moving to a desired position (so-called thread hanging goto) is performed. The fraudster operates the thread member to guide the subsequent game ball to the entrance part, for example, by blocking a part of the flow path, or by using a detection sensor provided in the entrance part. By reciprocating the illegal ball with respect to the detection area, it is misunderstood as if a large number of game balls have won, and the privilege is illegally acquired. For such an illegal act, for example, a large-scale preparatory work such as replacing the control device with an unauthorized one is unnecessary, and the discovery is likely to be difficult.

  Here, when the above-described fraud is attempted with the gaming machine shown in this feature, the thread-like member exists in the ball passage during the fraud. Here, the displacement and the thread-like member cross the sphere passage region of the spherical passage at a position where the movable body rotates about the shaft body and protrudes into the spherical passage and a position where the movable body is prevented from projecting into the spherical passage. Is caught by the movable body, and the thread-like member is drawn toward the shaft body by the rotation, and is entangled with the shaft body. As a result, the thread-like member is entangled with both the movable body and the shaft body, and the displacement of the thread-like member is suppressed. As a result, the flow of illegal spheres is hindered. In addition, even if a fraudulent person tries to pull the game ball back to the hand side by pulling the thread-like member or the like, such an operation itself is hindered under the situation where the thread is wound, and the illegal ball It becomes difficult to move freely. Thereby, it can contribute to the improvement of crime prevention of the gaming machine.

  In addition, by arranging the shaft body in parallel with the ball passage, it is possible to avoid the movable body from becoming unnecessarily large, and the occupied area of the configuration (security structure) related to winding of the thread-like member is unnecessarily large. Can be suppressed. Further, by configuring the spherical passage so that the passage direction of the portion where the open portion is formed and the longitudinal direction (axial direction) of the shaft body are the same direction, the spread of the occupied region is further suppressed. be able to. By the way, the fact that the shaft body and the ball passage are arranged in parallel is not necessarily limited to the case where the axial direction of the shaft body and the passage direction of the ball passage coincide with each other. Any device that is recognized to be provided side by side may be used. That is, it does not deny a curved ball passage or a deviation between the passage direction and the axial direction.

Feature A2. The passage wall portion includes a plurality of wall surface portions (rails 101 and 102 and a plate body 80a of the game board 80) having different directions,
The game machine according to Feature A1, wherein the opening portion is formed across adjacent wall surface portions of the plurality of wall surface portions.

  In the configuration in which the spherical passage is partitioned by a plurality of passage wall portions as shown in the feature A1, variation may occur in which part of the spherical passage the above-described thread-like member is positioned around the open portion. Here, by forming the open portion over a part of the adjacent wall surfaces of the plurality of wall surface portions, the movable body can traverse the widest possible range of the movable body that is rotationally displaced. The function shown in the feature A1 can be performed well.

  In the configuration in which the game ball rolls or slides on the specific passage wall in a state where the game ball is pressed against the specific passage wall by its own weight or the like, the disposition target of the opening portion is the specific passage wall. It is preferable to use other passage wall portions except for. According to this structure, it can suppress that an open part becomes a factor which disturbs the motion of a game ball.

  Feature A3. The game machine according to Feature A1 or Feature A2, wherein the movable body is integrated with the shaft body and is displaced so as to follow the rotation of the shaft body.

  When the winding function shown in the feature A1 or the like is exhibited, the thread-like member is easily entangled with the connecting portion between the movable body and the shaft body. For this reason, it is assumed that the load caused by the weight of the game ball and the operation of the fraudster (pulling of the thread-like member) is increased at the connecting portion between the movable body and the shaft body.

  For example, in the configuration in which the movable body is rotatably held by the shaft body, it is difficult to ensure the strength of the connecting portion between them, and there is a concern that the deformation function is likely to be impaired due to the above-described disadvantages such as deformation. In this regard, if the movable body and the shaft body are integrated (for example, integrally molded) as shown in this feature, the connecting portion between the movable body and the shaft body can be easily reinforced, and the load generated in the connecting portion. Therefore, it is possible to suppress the occurrence of inconveniences such as bending and breakage in the movable body and the shaft body.

  When the movable body is integrated with the shaft body as shown in this feature, the movable body may be integrally formed so as to protrude in the direction intersecting the axial direction of the shaft body.

Feature A4. The shaft body extends on both sides upstream and downstream of the spherical passage with respect to the open portion,
The game machine according to any one of features A1 to A3, wherein the movable body is provided in an intermediate portion of the shaft body.

  The thread-like member caught on the movable body is drawn to the shaft body through the opening. Here, as shown in this feature, if the shaft body is configured to extend in the upstream and downstream directions from the open portion and the movable body is disposed in the middle portion of the shaft body, the thread shape drawn to the shaft body The member is wound around both sides of the shaft body with the movable body as the center. Thus, the freedom degree of illegal ball operation can be reduced suitably by earning the number of windings. Further, by limiting the portion through which the thread-like member passes to the open portion that constitutes the operation region of the movable body, even if the thread-like member is pulled, the force can be distributed to the passage wall portion side. It is possible to make it difficult to release the entanglement of the thread-like member.

  In addition, by forming flange portions projecting in the radial direction of the shaft body (for example, the direction intersecting the axial direction of the shaft body) on both sides of the shaft body, it is possible to avoid the yarn from being easily pulled up and down of the shaft body. This can be expected to further improve the winding function.

  Feature A5. The movable body is formed with a guiding portion (guidance inclined surface 323) for guiding the thread touching the movable body toward the shaft body with the displacement of the movable body. Thru | or the game machine as described in any one of characteristics A4.

  According to the feature A5, the thread-like member that has touched the movable body is guided to the shaft body side by the guiding portion as the movable body is displaced. Thus, by guiding the thread-like member to the shaft body side, resistance (such as tension of the thread-like member) when the movable body is displaced can be reduced, and the winding operation can be facilitated. Further, the winding function of the thread-like member can be suitably exhibited by guiding the thread-like member to the shaft body side.

Feature A6. The ball passage is configured such that a game ball passing through the ball passage moves in a state of contacting a specific passage wall portion of the passage wall portion,
The movable body crosses a trajectory through which a central portion of a game ball that moves in contact with the specific passage wall portion and a trajectory through which the movable body passes as the shaft body rotates. The gaming machine according to any one of features A1 to A5, wherein the gaming machine is configured.

  Usually, a certain allowance is given to the width dimension etc. about the ball passage for the purpose of ensuring smooth movement of a game ball. This is beneficial in ensuring smooth movement of the game ball, but the margin can be a factor for diversifying the passage route of the game ball. Thus, if the game ball is moved in contact with a specific passage wall, variations in the passage route are reduced.

  Here, in this feature, the trajectory through which the central portion of the game ball that moves while the movable body is in contact with the specific passage wall portion intersects the trajectory through which the movable body passes as the shaft body rotates. Therefore, while securing the catch between the movable body and the thread-like member, it is possible to prevent the movable body and its operation area from becoming unnecessarily large and enjoy the winding function of the thread-like member. Become.

Feature A7. A game board (game board 80) having a game area (game area PE) formed on the front surface;
Game ball launching means (game ball launching mechanism 110) for launching a game ball based on a player's launch operation;
A guide rail (guide rail 100) that is provided upright from the front of the game board and guides the game ball launched by the game ball launching means to the game area;
The guide rail is composed of a pair of opposing rail members (inner rail 101 and outer rail 102),
The gaming machine according to any one of features A1 to A6, wherein a region surrounded by the rail members and the front surface of the game board constitutes the ball passage.

  With respect to the thread-like member fixed to the illegal ball described above, if the tension becomes too strong, the winding function shown in the feature A1 or the like cannot be performed well, and the thread-like member bends when the tension is extremely weak. Then, it is assumed that the positions become various and it is difficult to wind the thread-like member well.

  In this regard, with respect to the guide rail provided on the game board, the game ball moves with a certain degree of momentum. At this time, if the thread-like member is held firmly, it will hinder the launch of the game ball. Therefore, the fraudulent person must leave the thread-like member to move so that the thread-like member can move freely, and does not hold it. It is assumed. For this reason, when an illegal ball is fired, the thread-like member moves following it, and the tension described above does not become excessively strong or weak. Therefore, the winding function can be demonstrated well.

Feature A8. The rail member comprises an inner rail member and an outer rail member that form an arc shape that protrudes outward from the center of the game board,
The shaft body and the movable piece are disposed on the inner rail member side,
The game machine according to Feature A7, wherein the opening portion is provided in the inner rail member.

  As shown in feature A8, in the gaming machine in which the guide rail is constituted by the inner and outer rail members having an arc shape, the game ball fired by the game ball launching means is applied to the outer rail member by the centrifugal force acting on itself. Move along (in contact with the outer rail member). Here, when the opening portion is formed on the outer rail member, the behavior of the game ball may be disturbed by being caught by the end of the opening portion or the like when passing through the opening portion. This is not preferable because it can hinder the smooth movement of the game ball. In this respect, as shown in this feature, by disposing the movable body and the shaft body on the inner rail member side and providing the open portion on the inner rail member, it is possible to make it difficult to cause such inconvenience. Therefore, it is possible to suppress difficulty in smoothly guiding the game ball due to the provision of the winding function.

Feature A9. A gaming machine front surface portion (front door frame 14) formed so as to cover the gaming area from the front of the gaming machine and to make the gaming area visible.
The open portion is formed so as to straddle the game board and the inner rail member,
The game board side open part (slit 80b) formed in the game board at the open part covers the game board side open part at least in a situation where the game ball reaches the game board side open part. The gaming machine according to Feature A8, wherein a cover portion (arm 302) that is in a state is provided.

  In a gaming machine, a gaming area is covered by a gaming machine front portion (for example, a glass panel), and various measures are taken to avoid a gaming ball colliding with the gaming machine front portion. For this reason, the game ball is likely to move along the front surface of the game board. Here, when the winding function of the thread-like member is to be demonstrated well, it is preferable to form the opening portion so as to straddle the inner rail member and the game board, but in this case, the game board side There is a possibility that a game ball contacts the opening. Certainly, it is possible to devise so that the game ball moves without touching the game board by adjusting the inclination of the guide rail and the launch angle of the game ball. The configuration can be a factor causing interference between the game ball and the front of the gaming machine.

  In this feature, by providing a cover part that covers the game board side opening part, it is possible to suppress the game ball from being caught on the edge part of the game board side opening part, and to suppress the occurrence of the above-mentioned inconvenience. Yes.

  Feature A10. According to any one of features A1 to A9, characterized in that the movable body is provided with a rotating means (drive motor 351) for rotating the movable body so as to cross the ball passage area based on the launch of the game ball. The gaming machine described.

  According to the feature A10, the movable body rotates based on the game ball being fired. According to such a configuration, the more the game ball is fired, the more the thread-like member is wound up. For example, when trying to guide the following game ball to the entrance part by the illegal ball, the degree of wrapping is increased by the launch of the subsequent game ball and it becomes difficult to adjust the position of the illegal ball. The thread-like member wound around the shaft body or the like is likely to remain. In addition, when trying to generate an illegal prize by reciprocating the illegal ball at the entrance, if the game ball is fired as a camouflage, the degree of winding of the thread-like member as in the case described above Becomes stronger, and it becomes difficult to operate the illegal sphere, and the trace is likely to remain. For the above reasons, employing the rotating means shown in this feature can contribute to further strengthening the crime prevention function.

Feature A11. The movable body is formed with a contact surface (contact surface 322) that protrudes into the ball passage and hits a game ball that passes through the ball passage,
The gaming machine according to Feature A10, wherein the rotating means includes the contact surface, and is configured to rotate the movable body when the contact surface is pressed by a game ball.

  According to the feature A11, since the movable body can be rotated using the kinetic energy of the game ball, an actuator or the like for displacing (rotating) the movable body becomes unnecessary. Thereby, it can suppress that the structure for implement | achieving a winding function enlarges, and can reduce the restrictions concerning arrangement | positioning of the said structure.

  When the game ball hits the contact surface, naturally a reaction force is applied to the game ball, but this reaction force is reduced by the displacement of the movable body (by escape). Therefore, in comparison with the case where the game ball collides with the edge portion or the like of the opening portion formed so as to be immovable, it is possible to make it difficult for the disadvantage that the behavior of the game ball is greatly disturbed.

Feature A12. The ball passage is a passage through which a game ball launched to the game area (game area PE) based on the launch operation reaches the game area,
The rotating means includes
Driving means for rotating the movable body;
The gaming machine according to feature A10, further comprising drive control means for drivingly controlling the drive means so that the shaft body rotates based on the launch of a game ball.

  According to the feature A12, the movable body can be rotated by the driving unit. According to such a configuration, the winding function can be preferably improved.

  For example, in a gaming machine that launches game balls at regular intervals, after the previous game ball is launched and passes through the opening part, the rotation is performed in a period until the next game ball passes through the opening part. May be configured to return to the standby state.

Feature A13. Load detecting means (MPU 249 of the power supply / launch control device 243) for detecting a load when rotating the shaft body;
Load determination means (MPU 249 of the power supply / launch control device 243) for determining whether or not the load detected by the load detection means is larger than a predetermined value set in advance;
An abnormality notification execution unit (notification / production control device 140) that performs abnormality notification when the load determination unit determines that the detected load is greater than the predetermined value. The gaming machine according to Feature A12.

  According to the feature A13, when the thread-like member is entangled with the movable body or the shaft body, the rotational load generated when the movable body is rotated increases. Therefore, by performing abnormality notification when the rotational load exceeds a predetermined value, it is possible to notify the game hall manager or the like that there is a possibility that an illegal act is being performed. This can contribute to early detection of fraud.

  Feature A14. Any one of the features A1 to A13, wherein a restricting means (a one-way lock mechanism including a gear portion 313 and a stopper piece 306) is provided to restrict the rotational direction of the movable body to one direction. The gaming machine described in one.

  According to the feature A14, in a situation where the thread-like member is entangled with the movable body or the shaft body, even if the fraudulent person pulls the thread-like member in order to solve the situation, the movable body does not reverse, It is possible to avoid the filamentary member from being detached from the movable body or the like by such an action.

  In addition, when the thread-like member is forcibly pulled strongly, the thread-like member is cut and the thread-like member remains entangled with the movable body and the shaft body, leaving a trace of fraud. This makes it easier to detect the fact that fraud has been performed, and can contribute to the strengthening of the crime prevention function.

  Feature A15. The gaming machine according to Feature A14, wherein the opening portion is formed in a size that prevents a game ball from passing therethrough.

  When the thread-like member is made of a material having a considerable strength and smoothness, there is a possibility that the game ball is pulled back to the opening portion side by pulling the thread-like member. Even in such a case, by providing a configuration in which the game ball cannot pass through the opening portion, the game ball is clogged in the ball passage, and it is difficult for the fraudster to continue the game.

Feature A16. A ball passage (guide passage 103) through which game balls pass,
Opening portions (slits 80b and 101b) provided in passage wall portions (inner rail 101 and plate body 80a of game board 80) defining the ball passage and penetrating into and out of the ball passage;
By rotating around the shaft body (shaft body 301) provided outside the spherical passage and the shaft body, the position projecting into the spherical passage through the opening and the projection into the spherical passage are avoided. A gaming machine comprising: a winding mechanism (winding mechanism 300) having a movable body (arm 302) that is displaced so as to cross the ball passage region of the ball passage at the position where the ball passage is provided.

  In a gaming machine such as a pachinko machine, for example, a game ball (hereinafter also referred to as an illegal ball) to which a tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area, and the illegal ball is operated by operating the yarn-like member. An illegal act of moving to a desired position (so-called thread hanging goto) is performed. The fraudster operates the thread member to guide the subsequent game ball to the entrance part, for example, by blocking a part of the flow path, or by using a detection sensor provided in the entrance part. By reciprocating the illegal ball with respect to the detection area, it is misunderstood as if a large number of game balls have won, and the privilege is illegally acquired. For such an illegal act, for example, a large-scale preparatory work such as replacing the control device with an unauthorized one is unnecessary, and the discovery is likely to be difficult.

  Here, when the above-described fraud is attempted with the gaming machine shown in this feature, the thread-like member exists in the ball passage during the fraud. Here, the movable body rotates about the shaft and is displaced so as to cross the sphere passage area of the sphere passage to a position where the movable body protrudes into the sphere passage and a position where the protrusion into the sphere passage is avoided. The member is caught by the movable body, and the thread-like member is drawn toward the shaft body by the rotation, and is entangled with the shaft body. As a result, the thread-like member is entangled with both the movable body and the shaft body, and the displacement of the thread-like member is suppressed. As a result, the flow of illegal spheres is hindered. In addition, even if a fraudulent person tries to pull the game ball back to the hand side by pulling the thread-like member or the like, such an operation itself is hindered under the situation where the thread is wound, and the illegal ball It becomes difficult to move freely. Thereby, it can contribute to the improvement of crime prevention of the gaming machine.

  In addition, by arranging the shaft body in parallel with the ball passage, it is possible to avoid the movable body from becoming unnecessarily large, and the occupied area of the configuration (security structure) related to winding of the thread-like member is unnecessarily large. Can be suppressed. Further, by configuring the spherical passage so that the passage direction of the portion where the open portion is formed and the longitudinal direction (axial direction) of the shaft body are the same direction, the spread of the occupied region is further suppressed. be able to.

<Feature B group>
The following feature group B is “Some game machines such as pachinko machines have a game board having a game area formed on the front surface. The game board is fired based on a player's launch operation. There are various game parts such as a guide rail that guides the game balls to the game area and a game entrance that receives game balls that flow down the game area. The detected information is detected by a detection sensor provided in the ball unit, and the detected information is transmitted to the control device, which performs a process for giving a player a privilege such as paying out a game ball based on this information. (For example, refer to Japanese Patent Application Laid-Open No. 2003-190511.) In a situation where game balls are moving, these game balls can be charged by, for example, rubbing against the game parts or the game board. Generates noise, which is described above. There is a risk of affecting the operation of various electrical devices such as detection sensors and control devices, etc. Especially in the configuration where the game ball moves vigorously in the state of contact, such as the rail member described above, the game ball is charged. There is also a possibility that the guide rail itself may be charged, that is, the game ball and the guide rail released to the game area are likely to generate the above-mentioned noise due to the relationship between the guide rail and the game ball. It is likely that the possibility that the noise will have some influence on the electrical equipment as a result is high. ”

Feature B1. A game board (game board 80) in which a game area (game area PE) is formed;
A support frame (inner frame base body 50) for supporting the game board;
Game ball launching means (game ball launching mechanism 110) for launching a game ball based on a player's launch operation;
A guide rail (guide rail 100) provided so as to stand up from the front surface of the game board and guiding the game ball fired from the game ball launching means to the game area;
The game board is formed with a through hole penetrating in the thickness direction of the game board, and the guide rail has leg portions (leg portions 101a, 102a) protruding to the back side of the game board through the through hole,
The leg portion is electrically connected to a conductive game board side conductive member (conductive member 400, 500) having conductivity provided on a back surface portion of the game board,
The support frame includes a support frame side conductive member (frame members 55 and 57) having conductivity as a frame portion for reinforcing the support frame.
The game board-side conductive member is electrically connected to a support frame-side conductive member of the support frame in a state where the game board is supported by the support frame.

  In a type of gaming machine in which the launched game ball is guided to the game area by the guide rail, there is a possibility that both the game ball and the guide rail are charged by moving the game ball in contact with the guide rail. is there. If the game ball flows down the game area while being charged, the charge may affect an electric device or the like (for example, a wireless communication device) mounted on the game machine. Therefore, as shown in this feature, when a charge is generated on the game ball or the induction rail while the game board is mounted on the support frame, the charge is generated on the leg of the induction rail → the game board side conductive member → the support. If it is configured to flow through the frame side conductive member (grounded configuration), charging of the guide rail and the game ball can be suppressed. Thereby, it becomes possible to suppress the influence on the said electric equipment etc.

Feature B2. The guide rail has a pair of rail members (an inner rail 101 and an outer rail 102) that face each other across a passing area of a game ball,
The portion sandwiched between the rail members is a ball passage (guide passage 103),
The leg portions respectively provided on the rail members are arranged so as to face each other with the ball passage in front of the gaming machine,
The gaming machine according to Feature B1, wherein the game board-side conductive member has a connecting portion (for example, an extending portion 502) that connects both the leg portions.

  According to the feature B2, a set of rail members can be grounded together by adopting a structure in which the leg portions that are opposed to each other are connected by the connecting portion. According to such a configuration, it is possible to contribute to simplification of the configuration relating to grounding (game board side conductive member) as compared to the case where each rail member is grounded individually.

Feature B3. The game board is formed using a synthetic resin material having transparency, and is configured so that the back of the game board can be visually recognized through the game board from the front of the game machine.
The connecting portion is formed so as to extend from a main body portion (mounting base 501) provided with an energization function with the support frame side conductive member in the game board side conductive member,
The gaming machine according to Feature B2, wherein the game board-side conductive member is disposed such that the main body portion is located behind one of the pair of rail members.

  As shown in feature B3, if the gaming board is transparent and the configuration arranged behind the gaming board is visible, the area behind the gaming board can be used as a space for improving the appearance of the gaming machine. However, when the ground structure shown in the feature B2 is applied to such a configuration, although it is preferable to suppress the influence on the electric equipment and the like, the above-mentioned appearance is improved by making the game board side conductive member visible. Concerns will be likely to be disturbed. In this regard, as shown in this feature, if the main body of the game board side conductive member is arranged behind the rail member, the game board side conductive member is less noticeable, and the effects shown in the feature B1 are exhibited. However, it is possible to prevent the appearance from being hindered.

  For example, if each rail member has a plurality of leg portions, further improvement of the earthing function can be expected. In this case, the main body of the game board-side conductive member may be configured to extend along any rail member. According to this configuration, it is possible to suppress a decrease in appearance due to an increase in size and functional enhancement of the game board-side conductive member.

Feature B4. The set of rail members includes an inner rail member (inner rail 101) and an outer rail member (outer rail 102) formed in an arc shape protruding outward from the game area,
The outer rail member is extended to extend deeper in the guiding direction than the inner rail member,
In the ball path of the guide rail, an exit portion (exit portion 105) that is open to the game area is formed at a position where the inner rail member has an end on the far side in the guide direction.
The leg portion of the inner rail member is provided at an end portion of the inner rail member on the outlet portion side, and the leg portion of the outer rail member is disposed at a position facing the leg portion of the inner rail member. The gaming machine according to Feature B2 or B3, wherein

  In the configuration in which the guide rail is grounded through the leg portion as shown in the feature B1, the function is likely to deteriorate at a position farther from the leg portion (ground portion). The game balls that have jumped out from the exit portion of the guide rail flow away from the outer rail and flow down the game area by their own weight. Considering the actual situation of such games, by arranging the grounding structure at the exit portion, the charge accumulated in the game ball immediately before flowing into the game area can be released, as shown in the feature B1 etc. An effect can be exhibited suitably.

  In addition, about the edge part by the side of the exit part in an inner rail member, we are anxious about intensity | strength falling easily compared with another site | part. Therefore, by providing a leg portion at this end portion and integrating both rails with a game board-side conductive member (specifically, a connecting portion), the above-described concern about strength can be eliminated.

Feature B5. The game board-side conductive member is a metal member, and a part of the conductive board-side conductive member is a protrusion protruding to the front side of the game board at a position adjacent to the tip of the inner rail.

The gaming machine according to Feature B4, wherein:

  In a gaming machine such as a pachinko machine, for example, a game ball (hereinafter also referred to as an illegal ball) to which a tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area, and the illegal ball is operated by operating the yarn-like member. An illegal act of moving to a desired position (so-called thread hanging goto) is performed. The fraudster operates the thread member to guide the subsequent game ball to the entrance part, for example, by blocking a part of the flow path, or by using a detection sensor provided in the entrance part. By reciprocating the illegal ball with respect to the detection area, it is misunderstood as if a large number of game balls have won, and the privilege is illegally acquired. For such an illegal act, for example, a large-scale preparatory work such as replacing the control device with an unauthorized one is unnecessary, and the discovery is likely to be difficult.

  Here, when the cheating is attempted with the gaming machine shown in this feature, the thread-like member is connected to the cheating ball through the exit portion of the ball passage during the cheating. Here, when the thread-like member is pulled to adjust the position of the illegal sphere, the thread-like member moves in the direction opposite to the guiding direction and is cut by the cutting means. As a result, it becomes difficult to freely operate (move) the illegal ball, which can contribute to the improvement of crime prevention of the gaming machine.

  In the first place, when a game board side conductive member is provided for grounding the guide rail, a metal member is employed as the game board side conductive member, and a certain level of strength is ensured. In particular, by connecting the inner and outer two rail members, the game board-side conductive member has a certain size, and it is easy to secure its fixing strength. Considering the fact that such a member exists at the exit portion of the guide rail as shown in feature B4, it is easy to ensure the strength of the cutting means by providing a cutting means on the game board side conductive member. realizable.

  According to the feature B6, when the game ball is moving vigorously in the guiding direction along the outer rail member, the game ball can be prevented from coming into contact with the cutting means. On the other hand, when the game ball is separated from the outer rail member and flows down the game area, the thread-like member is separated from the extension of the ball passage area and falls to the expansion area. Thereby, the presence of the cutting means can ensure the crime prevention function shown in the feature B6 while ensuring the guidance function of the game ball to the game area.

Feature B7. The projecting portion has a first plate-like portion (first plate portion 511) that stands up with respect to the front surface of the game board and has a plate surface facing the same side as the exit portion.
The first plate-like portion is inclined so as to incline to the back side in the guide direction with respect to the guide direction at the outlet portion, and the cutting means is provided at an upper end portion (end portion 512) of the first plate-like portion. The gaming machine according to Feature B6, wherein a first cutting portion (first blade portion 513) to be formed is formed.

  According to the feature B7, the first cutting portion is formed at the upper end portion of the first plate-like portion that is inclined so as to be inclined toward the guidance side with respect to the front surface of the game board. By tilting in this way, even if the momentum of the game ball that has been fired is not sufficient and the game ball hits the first plate-like part (particularly the cutting part), the cutting part or the game ball Can be prevented from being damaged or damaged.

Feature B8. The protrusion is configured to be visible from the front of the gaming machine,
The gaming machine according to Feature B7, wherein the first cutting part is a blade part and is inclined downward toward the front of the gaming machine or behind the gaming machine.

  According to the feature B8, by pulling the thread member, the thread member can move (shift) along the inclination of the cut portion. Thus, by urging the movement along the blade portion of the thread-like member, the cutting function can be suitably exhibited.

  In particular, when the blade part is inclined downward toward the front of the gaming machine, it is easy for a person who intends to perform an illegal act to visually recognize the presence of the blade part. Thereby, it is possible to give an impression that it is difficult to perform an illegal act using an illegal ball, and it is possible to contribute to an improvement in the deterrence of the illegal act.

Feature B9. The protruding portion is configured to be visible from the front of the gaming machine, and the first cutting portion is a blade portion,
The gaming machine according to Feature B7 or Feature B8, wherein the first plate-like portion is formed to be inclined with respect to a front surface of the game board.

Tilt it against. Thereby, the part which is contacting the 1st cutting part in a thread-like member becomes easy to move on the 1st cutting part with the pulling operation by a fraudulent person, and can contribute to the further improvement of the above-mentioned cutting function.

  In addition, since the first plate-shaped part is inclined with respect to the front of the game board, the person who intends to cheat grasps the presence of the blade part visually compared with the case of standing upright. It becomes easy to do. Thereby, it is possible to give an impression that it is difficult to perform an illegal act using an illegal ball, and it is possible to contribute to an improvement in the deterrence of the illegal act.

Feature B10. The projecting portion is formed so that it stands up with respect to the front surface of the game board and the plate surface faces in a direction different from the first plate-like portion, and is connected to the first plate-like portion at one end thereof. It has a second plate-like part (second plate part 521),
A second cutting portion (second blade portion 515) connected to the first cutting portion is formed at an end of the first plate-like portion on the front side of the gaming machine,
The second cutting portion constitutes the cutting means together with the first cutting portion, and is inclined downward so that the amount of protrusion from the front surface of the game board is reduced toward the connecting portion with the second plate-like portion. The gaming machine according to any one of features B7 to B9, wherein:

  According to the feature B10, when the thread-like member is cut based on the pulling operation of the thread-like member, a load is applied to the cutting portion. Such a load is assumed to increase as the strength of the thread-like member increases. As shown in this feature, in the configuration in which the first plate-like portion and the second plate-like portion are connected, the strength of the first plate-like portion is increased at the connecting portion of both the plate-like portions. Therefore, by guiding the thread-like member toward the connecting portion, it is possible to make it difficult to cause inconveniences such as deformation of the cutting portion due to a load on the cutting portion, and to contribute to ensuring the cutting function.

  Note that a part of the technical idea shown in this feature is applied to the feature B5 and the like, and “the projecting portion faces a different direction from the first plate-like portion, and the first plate-like portion is at one end thereof. It is also possible to have a configuration having a second plate-like portion connected to each other.

  Feature B11. The game board has an insertion hole through which the protruding portion is inserted, and the protruding portion is engaged with the insertion hole. Any one of the features B5 to B10 The gaming machine described.

  According to the feature B11, the load generated in the protruding portion when the thread-like member is cut can be distributed to the game board, and deformation of the protruding portion can be suppressed. Thereby, it can contribute to the security | security of a cutting function.

Feature B12. The exit portion of the guide rail is provided with a restricting means (reverse prevention member 106) for restricting the game ball that has flowed into the game area from returning to the passage area.
The regulating means is
Having a contact portion that impacts after the game ball flows out of the exit portion;
The contact portion is configured to elastically deform based on the collision of the game ball to allow the passage of the game ball and return to the original state by the elastic force accumulated by the collision,

The gaming machine according to any one of features B5 to B11, wherein at least a part of the cutting means is positioned on the outer rail side with respect to a virtual tangent line in contact with the tangent line.

  According to the feature B13, in a situation where the game ball with the thread-like member reaches the game area beyond the restricting means, and the contact portion pushed by the thread-like member is displaced by the weight of the game ball, the thread-like member is cut. It will hit the department.

  The thread-like member is subjected to a stress that tends to be displaced to a position overlapping the tangent by the weight of the game ball and the pulling operation by the fraudster, and the stress causes the thread-like member to be pressed against the cutting means. As a result, the cutting function shown in the feature B5 or the like can be successfully performed.

  In addition, when a cutting function is given to the restricting means, a large force is applied to the restricting means, which may cause problems such as deformation in the restricting means. This is not preferable because the backflow of the game ball that the restriction means originally has becomes a factor that lowers the restriction function. For the above reason, it is preferable to arrange the cutting means between the regulating means and the outlet portion as shown in this feature.

Feature B13. The restricting means and the game board-side conductive member are arranged so that the abutting portion and the protruding portion are close to each other,

<Feature C group>
The following feature C group is: “Some game machines such as pachinko machines have a game board having a game area formed on the front surface. A game ball launched based on a player's launch operation is a game. By entering (winning) a pitching portion provided in the area, the winning is detected by a detection sensor, and the detected information is transmitted to the control device, and the player based on this information in the control device. (For example, refer to JP-A-2003-190511) A game machine of a type in which a privilege is given in response to a winning in such a winning part. In this case, there may be a difference in whether or not the game can be advantageously advanced depending on the winning occurrence rate (winning frequency) of the winning portion. In recent years, many games have been held. Various fraudulent acts have been reported on gaming machines aimed at enjoying the benefits of, for example, a game ball with a tip of a thread-like member such as a fishing line or a piano wire fixed to the game area, and There is a fraudulent act of manipulating a game ball with a member (so-called thread hanging goto), which can be used to, for example, guide a subsequent game ball to the entrance or By reciprocating the game ball with the thread-like member fixed to the detection area of the detection sensor provided in the ball part, it is misunderstood as if a lot of game balls have won, and the privilege is illegally acquired Such fraudulent acts are less conspicuous than fraudulent acts such as fraudulent fraud, and it is difficult for the hall manager to detect fraudulent acts visually. In view of the background and issues such as “there are no effective measures against such fraud, and there is still room for improvement in the crime prevention function of gaming machines in order to prevent such fraud.” It was made.

Feature C1. A gaming machine including a game ball launching mechanism (game ball launching mechanism 110) that launches a game ball toward a game area (game area PE),
The game ball launch mechanism is
A launch rail that defines the launch direction of the game ball (launch rail 112);
A ball feeding device (ball feeding device 113) that is arranged above the lower end of the firing rail and sends a game ball to the firing rail;
A launch unit (solenoid 111) that launches a game ball placed at a predetermined launch position on the launch rail;
The ball feeder is
A guide path (ball path 601X) for guiding the game ball to the launch rail;
Provided at the exit portion (exit portion 605X) of the guide passage, and prevents the feed of the game ball and the feed of the game ball from the guide passage to the launch position of the launch rail each time the game ball is fired. A movable piece (shutter 620X) that can be switched to a blocking state;
A part of the movable piece and a ball provided at an exit portion of the guide passage and at a position outside the passage route through which the game ball passes in the guide passage, when the movable piece is in the blocking state. A gaming machine having a facing portion (facing portion 615X) facing each other in the feeding direction.

  In a gaming machine such as a pachinko machine, for example, a game ball (hereinafter also referred to as an illegal ball) to which a tip of a thread-like member such as a fishing line or a piano wire is fixed is sent to the game area, and the illegal ball is operated by operating the yarn-like member. An illegal act of moving to a desired position (so-called thread hanging goto) is performed. The fraudster operates the thread member to guide the subsequent game ball to the entrance part, for example, by blocking a part of the flow path, or by using a detection sensor provided in the entrance part. By reciprocating the illegal ball with respect to the detection area, it is misunderstood as if a large number of game balls have won, and the privilege is illegally acquired. For such an illegal act, for example, a large-scale preparatory work such as replacing the control device with an unauthorized one is unnecessary, and the discovery is likely to be difficult.

  Here, when performing the above-described cheating, it is assumed that the cheating agent mixes the normal game ball and guides the cheating ball to the game ball launching mechanism, and sends it to the game area by the launch operation by the launching unit. . In this case, the illegal ball and the thread-like member move from the guide passage → the exit portion → the launch rail. As for the thread-like member, in order to adjust the movement destination after the illegal ball reaches the game area, the other end side portion is left in the hands of the fraudster. In other words, the thread-like member exists in the guide passage when the illegal ball is supplied to the firing rail by the ball feeding device. Here, the movable piece constituting the ball feeding device returns to the blocking state in order to block the movement of the subsequent game ball after the moving state in which the illegal ball is sent from the blocking state to the firing rail. At this time, the movement of the thread-like member is restricted by the thread-like member being sandwiched between the movable piece and the facing portion.

  In other words, even if an attempt is made to launch an illegal ball in such a state, the illegal piece is not successfully launched because the movable piece and the opposing portion prevent the movement of the filamentous member. Even if the gap between the movable piece and the facing portion is larger than the diameter (thickness) of the thread-like member, resistance that prevents at least the movement of the illegal ball occurs, so the illegal ball reaches the game area. Can be suppressed. When an attempt is made to use the illegal ball in an actual game hall, it is assumed that the game ball is arranged on the upstream side of the illegal ball in order to avoid the conspicuous filamentous member. In this case, the next game ball is sent to the launch rail, so that a plurality of game balls exist on the launch rail, and it is difficult to repeatedly approach the game area by repeatedly launching illegal balls. .

  For the reasons described above, it is possible to make it difficult to illegally enjoy a privilege using an illegal ball, and to contribute to the improvement of the crime prevention function.

Feature C2. The game ball passing through the guide passage is configured to move along the bottom surface of the guide passage.
The game machine according to C1, wherein the movable piece is provided on a bottom surface side of the guide passage, and the facing portion is provided on a side opposite to the movable piece across the passage path. .

  According to the feature C2, when the movable piece is switched to the blocking state, the overlap with the facing portion can be gradually increased, and in any of the state where the tension is applied to the thread-like member and the state where it is not applied The thread-like member can be smoothly guided between the movable piece and the facing portion.

  Feature C3. The launch rail is formed so as to incline upward and obliquely upward, and a game ball supplied from the ball feeding device is placed on an upper surface of the launch rail. The gaming machine according to Feature C1 or Feature C2, wherein a gap allowing movement (movement of a game ball with a thread) is formed.

  According to the feature C3, the holding portion of the thread-like member is located above the predetermined firing position. For this reason, the game ball launched by the launching unit is easily moved so as to float from the launching rail. By forming a gap that allows the movement of the game ball in the direction in which the illegal ball can move in this way, the momentum of the game ball is reduced and it is possible to avoid an excessive load on the launching unit.

  Also, if a fraudster who has determined that it is difficult to launch an illegal ball tries to collect the illegal ball, the game ball will be kept at hand even if the game ball is fired or the filamentous member is pulled. It will be difficult to return. Thus, making it difficult to collect illegal spheres can contribute to facilitating discovery of illegal activities.

  Feature C4. The game machine according to Feature C3, wherein the movable piece is disposed so as to be positioned downstream of the facing portion with respect to the opposing portion in the blocked state.

  According to the feature C4, when an upward force is applied to the illegal sphere at the time of launching the illegal sphere, the thread-like member can move upward along the mating surface between the movable piece and the facing portion. At this time, the boundary portion of the crank portion formed by the movable piece and the facing portion faces upward. As a result, the disadvantage that the load applied to the movable piece increases due to the movement of the thread-like member is less likely to occur, and the movable piece can be protected.

  Feature C5. The game machine according to Feature C4, wherein the movable piece is held so as to be movable up and down, and is configured to be in the blocking state when the movable piece is raised.

  As for the thread-like member, the fraudulent person holds the other end (the end on the side pulled out to the front side of the gaming machine) by hand, the presence of a subsequent game ball, and a ball feeding device. It is assumed that a certain amount of tension is applied for the reason that the passage leading to is generally meandering for the purpose of reducing the ball pressure. Further, from the viewpoint of improving the responsiveness of the game ball launch, the exit portion and the launch rail are generally arranged close to each other. For this reason, there is a possibility that the game ball has reached the predetermined launch position before switching to the blocking state. Here, as shown in this feature, in the configuration in which the movable piece is switched to the blocking state when the movable piece is lifted, the thread-like member that hits the upper end of the movable piece is lifted upward, and accordingly, the illegal ball is also pulled upward. Will be. In this way, by lifting the illegal ball upward, the hitting point is shifted when the launching unit pushes the illegal ball. Therefore, the illegal ball easily escapes upward, and the load generated on both the illegal ball and the launching portion is reduced. Thereby, the protection function of a launching part, a movable piece, and an opposing part can be improved, ensuring the launch control function of an illegal ball.

Feature C6. Drive control means (power supply / launch control device 243) for driving and controlling the movable piece so that the movable piece is in the feeding state and the blocking state,
The drive control means implements the drive control so that the game ball that has flowed out of the exit portion enters the blocking state from the feed state before reaching the predetermined launch position. The gaming machine according to any one of features C5.

  According to the feature C6, a normal game ball without a thread-like member can reach a predetermined launch position without any problem after flowing out from the exit portion, while an illegal ball to which the thread-like member is fixed is predetermined by the thread member. Reaching the launch position is hindered. Even if it is possible to reach the vicinity of the predetermined launch position, the hitting point by the launching unit is shifted, and it becomes difficult to move from the spot without moving along the launch rail.

  In addition, if the launch operation is continued, it is assumed that game balls are sent to the launch rail one after another, but the launch unit is set assuming that a plurality of game balls are fired at once. Therefore, the illegal ball stays on the launch rail and the game ball is likely to be jammed at the exit.

  For the above reasons, it is possible not only to make it difficult to launch illegal spheres, but also to make it impossible to reach the game area and to make it difficult to collect illegal spheres.

  Feature C7. The game machine according to Feature C6, wherein the drive control means maintains the movable piece in a blocking state in a normal state where a launch operation is not performed.
