Description

  The present invention relates to a gaming machine such as a pachislot machine or a pachinko machine capable of playing a game using a game medium (medal / pachinko ball), and in particular, a fraudulent special instrument (for example, a “flexible board”) The present invention relates to a gaming machine capable of preventing fraudulent acts aimed at malfunctioning of medal counting due to use of members.

  Conventionally, after inserting a medal or pressing a BET button, a start lever is operated to rotate and rotate a mechanical rotating reel (hereinafter referred to as a reel), and each reel is operated by pressing a stop button corresponding to each reel. There is known a game machine called a pachislot machine that stops the game and pays out medals in accordance with the combination of symbols stopped in the reel display window.

  In the case of such a pachislot machine, when 1 to 3 medals are inserted from the medal insertion slot and the start lever is operated, the reel is driven to rotate to change a plurality of symbols, and the player presses the stop button. Depending on the operation, the rotating symbols are stopped and displayed, and when the winning combination combination is stopped and displayed on the active line, a predetermined number of medals corresponding to the winning combination are paid out from the medal hopper through the payout slot. put out. Here, normally, a proper medal (regular medal) may be inserted from the medal slot, but an improper medal (illegal medal) may be inserted.

  For this reason, the pachislot machine determines whether the medal inserted from the medal slot is a regular medal or an illegal medal, and returns the illegal medal from the medal payout slot through a cancel shot, and the regular medal is counted as the number of medals. In addition, a medal selector for storing the medal from the medal passage in the medal hopper is provided.

[Configuration of Conventional Medal Selector 100a]
Here, an outline of the conventional medal selector 100a will be briefly described with reference to FIGS. 12 is a plan view showing the configuration of the medal selector 100a, FIG. 13 is a plan view showing the configuration of the medal selector 100a with the sub-plate 130 and the cancel shooter 140 removed, and FIG. 14 is a medal selector 100a. The back view of each is shown.

  As shown in the figure, the medal selector 100a includes a base plate portion 110 formed in a U-shape that forms an outer frame housing of the medal selector 100a main body, and a medal rail 111 that is formed on the main body surface and through which the medal passes. It comprises a covering sub-plate 130 and a cancel shooter 140 for discharging medals determined to be illegal medals. Below this medal selector 100a, a cancel chute 300 (FIG. 2) for paying out a medal determined to be an illegal medal and a medal discharged from the medal hopper 21 (FIG. 3) to the medal payout port 20 (FIG. 1). Is connected.

  A bracket 101 is attached and fixed to the base plate portion 110. The bracket 101 has a slope having a guide path 102 for guiding a medal determined as a regular medal by the medal selector 100a to the medal hopper 21 (FIG. 3). 103 is integrally formed.

  The sub-plate 130 has a flat plate-like main body 131, and a torsion coil spring 133 (torsion spring) is fixedly attached to a shaft 132 provided at an upper position of the main body 131. In the normal state, the sub plate 130 is pressed against the base plate portion 110 side by the elasticity of the torsion coil spring 133 wound around the shaft portion 132 fixed to the base plate portion 110, and passes the medal. Function as.

  Here, for example, when a medal clogging occurs in the medal selector 100a, the sub plate 130 can be opened against the elasticity of the torsion coil spring 133 by pressing the medal return button 12a (FIG. 1). The medals jammed by opening the sub plate 130 can be discharged into the cancel shooter 140. As described above, the medals discharged into the cancel shooter 140 are returned from the medal payout port 20 (FIG. 1) through the cancel chute 300.

  In addition, a medal inlet portion 112 that receives a medal inserted from the medal insertion slot 12 (FIG. 1) is provided at the upstream end of the base plate portion 110, and a medal inserted from the medal inlet portion 112 into the medal selector 100a. Is guided toward the downstream end along the medal rail 111 formed on the base plate portion 110. In addition, a select plate 113 that guides a regular-sized medal downstream of the medal rail 111 is disposed at an approximately middle position of the medal rail 111. Further, a medal pressure 114 (FIG. 13) to be pushed downward by a passing medal is disposed on the surface position of the medal rail 111 where the select plate 113 is disposed.

  The select plate 113 and the medal pressure 114 are configured to be pushed out to the cancel shooter 140 by the medal pressure 114 without guiding the medal by the select plate 113 when the inserted medal is smaller than the standard size. When the inserted medal is an appropriate medal (regular medal), the medal is guided along the select plate 113 and guided to the downstream side of the medal rail 111 while pushing the medal pressure 114.

  Normally, the select plate 113 is positioned at the guide position of the medal. However, under a predetermined condition (for example, when a predetermined number of medals are inserted, when an error occurs, when a game is started, etc.), the select plate 113 is placed on the medal. The medals inserted from the medal slot 12 are forcibly discharged to the cancel shooter 140. Reference numeral 116 denotes a magnet arranged on the medal rail 111. A medal attracted (magnetized) to the magnet 116 is discharged to the cancel shooter 140 as a non-standard medal (illegal medal).

  A photo sensor 117 (FIG. 14) is disposed in the vicinity of the medal pressure 114. The photo sensor 117 transmits a medal passage signal to the pachislot machine 1 while the medal pressure 114 is pressed by the medal passage. Output. That is, the photo sensor 117 detects that a medal clogging has occurred inside the medal selector 100a or that some unauthorized operation has been performed. For example, when an instrument other than a medal is inserted into the medal selector 100a, the pressing time against the medal pressure 114 is longer than a predetermined time (200 msec or longer). In this case, an error signal is sent and the medal counting sensor 120 is sent. The medal count by is disabled.

  Further, on the downstream side of the medal rail 111, two medal counting sensors 120 (double reflection type photosensors) having a light emitting element and a light receiving element are disposed. A count of medals passing on the medal rail 111 (medal count) and abnormal operations such as a clogged medal and an illegal operation are detected. The medals that have passed the medal counting sensor 120 are stored in the medal hopper 21 (FIG. 3) via the slope 103 provided on the bracket 101.

  Further, on the downstream surface of the medal rail 111, a medal stopper portion 126 and an after medal pressure 127 (FIG. 13) are provided. The medal that is not guided by the select plate 113 positioned at the medal discharge position is pressed by the medal pressure 114 and abuts the upward medal pressure 127 and the medal stopper 126 that protrude upward. The medals are discharged toward the cancel shooter 140.

  Next, with reference to FIG. 15A and FIG. 15B, a passage route of medals determined to be regular medals and medals determined to be illegal medals will be described. That is, as shown in FIG. 15A, a medal inserted from the medal insertion slot 12 passes through the medal rail 111 from the medal inlet 112 and is guided downstream of the medal rail 111 by the select plate 113. It is counted by a medal counting sensor 120 provided at the downstream end, and is stored in the medal hopper 21 (FIG. 3) through the guide path 102 of the slope 103.

  On the other hand, as shown in FIG. 15-2, in the case of an illegal medal, this medal passes through the medal rail 111 from the medal slot 12, but is not guided by the select plate 113, so that this medal is received by the medal pressure 114. Pressed and discharged from the medal rail 111a into the cancel shooter 140 (FIG. 12).

  As described above, a medal that has dropped into the cancel shooter 140 of the medal selector 100a is returned from the medal payout port 20 through the cancel chute 300 (FIG. 2) connected to the lower side of the medal selector 100a.

  As described above, the medal selector 100a determines the authenticity of the medal, detects the medal determined to be a regular medal with the medal counting sensor 120 (counting the number of medals), and discharges this medal to the medal hopper 21. A function and a function for returning a medal determined to be an illegal medal from the medal payout slot 20 through the cancel chute 300 from the cancel shooter 140 are provided.

  Here, the game by the pachislot machine 1 rotates the reel in accordance with the number of medals (medal count) detected by the medal counting sensor 120 provided inside the medal selector 100a, so it is not necessary to actually insert medals. If the medal counting sensor 120 can be erroneously operated, it is possible to play a game without filling the credit number (maximum, 50) or using medals. For this reason, conventionally, an illegal act using a special instrument for fraud (for example, an illegal member such as a “flexible substrate”) intended to malfunction the medal counting sensor 120 may be performed.

  Hereinafter, the outline of the above-described special tool for fraud (falsified member) will be briefly described. FIG. 16 is a configuration diagram showing an outline of an unauthorized member 121 (for example, “flexible substrate”) used as an unauthorized special instrument. As shown in the figure, the unauthorized member 121 is provided on the base 122 that is formed in accordance with the shape of the medal rail 111 (FIG. 15A) of the medal selector 100a and on the base end side of the base 122. The switch 123 and the two light emitting elements 125 provided at the front end portion 124 of the base material 122 are inserted into the medal counting sensor 120 at the position where the front end portion 124 of the unauthorized member 121 is inserted. By turning ON / OFF 123, the light emitting element 125 blinks, thereby causing a medal count malfunction.

  As described above, in the past, illegal actions aimed at malfunctioning of medal counting using an illegal member may be performed. Therefore, in order to prevent an illegal action when playing a game, the medal selector 114 is provided, and an illegal act prevention measure based on the pressing time by the medal pressure 114 is taken.

  Further, as a conventional technique for preventing an illegal act by this type of illegal member, for example, in Patent Document 1, when a medal selector is removed from a gaming machine for the purpose of fraud improvement, the removal of the medal selector is detected. In addition, a gaming machine is disclosed that includes a notification means for notifying that there has been an unauthorized removal based on the removal history information (see Patent Document 1).

  According to the prior art disclosed in Patent Document 1 described above, when the medal selector is removed from the gaming machine for the purpose of fraud improvement, the removal of the medal selector is detected, and the illegality is determined based on the removal history information. Therefore, it is possible to accurately prevent an illegal act before performing an illegal act.

  However, in the case of countermeasures against fraud using the members provided in the conventional medal selector described above, it is still not sufficient as a countermeasure for preventing fraudulent acts for the purpose of malfunctioning the medal count.

  That is, in the case of the anti-tampering countermeasure provided in the conventional medal selector described above, when the unauthorized member 121 is inserted into the medal selector 100a, the medal pressure 114 is pressed by the unauthorized member 121 for a predetermined time or more. Therefore, the medal count is not performed by error detection. However, in the case where the illegal member 121 is actually inserted into the medal selector 100a to perform an illegal act for the purpose of malfunctioning the medal count, there is a method in which the illegal member 121 is not brought into contact with the medal pressure 114.

  Specifically, if the unauthorized member 121 is inserted into the medal selector 100a with the sub-plate 130 located above the medal rail 111 opened, the medal counting sensor 120 is not pressed without pressing the medal pressure 114. The illegal member 121 can be made to reach the position. That is, by intentionally opening the sub-plate 130, the error detection by the medal pressure 114 is avoided without contacting the unauthorized member 121 to the medal pressure 114, and the unauthorized member 121 reaches the position of the medal counting sensor 120. Can be made. From the above, there is a problem that an illegal act using the illegal member 121 cannot be reliably prevented.

  In addition, in the case of countermeasures against fraudulent acts in which the removal of the medal selector disclosed in the prior art publication is acquired as history information and an unauthorized removal is detected, similarly, the medal selector is improved in particular. Therefore, by performing the opening / closing operation of the sub-plate, it is possible to cause a malfunction of the medal count by avoiding the error detection by the medal pressure 114. It cannot be said that it is sufficient as a measure for preventing fraudulent acts caused by unauthorized members.

  Accordingly, the present invention has been made to solve the above-described problems of the prior art, and an object thereof is to provide a gaming machine that can surely prevent an illegal act by an unauthorized member for the purpose of malfunctioning a medal count. And

An error signal for notifying medal count based on the passage shielding member that follows the direction and the deviation angle of the passage shielding member. A state detection sensor, and the passage shielding member is biased to follow the opening direction of the sub plate when the sub plate is opened when the unauthorized member is inserted, and the medal is accompanied by the passage of the medal. The error state detection sensor is biased to follow the opening direction of the sub plate during the opening operation of the sub plate. An error signal for invalidating the medal count is notified based on the angle.

  According to the present invention, an unauthorized member detecting device that detects insertion of an unauthorized member is disposed at a position facing the sub plate of the medal selector, and the unauthorized member detecting device is a path that is biased following the opening and closing direction of the sub plate. And an error state detection sensor for notifying an error signal for invalidating the medal count based on the bias angle of the passage shielding member. The error state detection sensor is configured to open the subplate during the opening operation of the subplate. Since the error state that invalidates the medal count is activated based on the bias angle of the passage shielding member that deviates following the opening direction of the passage, even if an illegal member is inserted with the sub-plate open, the medal count It is possible to prevent malfunctions caused by sensors, which can reliably prevent fraudulent acts aimed at malfunctioning medal counts. That.

  Further, in the invention according to claim 2, in the above invention, the passage shielding member is biased following the opening direction of the sub plate when the sub plate is opened by the insertion of the unauthorized member. While the passage of the unauthorized member is allowed, the passage of the unauthorized member pulled back from the downstream side of the medal rail toward the upstream side is blocked.

  According to the present invention, the passage shielding member is a tip portion of the passage shielding member that is biased by the opening operation of the sub-plate even when the unauthorized member once inserted into the medal selector is pulled back from the inside of the medal selector. In this way, the illegal member collides with each other, whereby it is possible to prevent the illegal member from being pulled back, and it is possible to accurately determine that the illegal act by using the illegal member has been performed.

  According to a third aspect of the present invention, in the above invention, the passage blocking member is provided with a passage blocking portion that prevents passage of an unauthorized member that is pulled back from the downstream side of the medal rail toward the upstream side. It is characterized by being.

  According to the present invention, the passage of the unauthorized member that is pulled back from the downstream side of the medal rail toward the upstream side can be prevented by the passage blocking portion formed in the passage shielding member, so that the unauthorized member is further pulled back. In addition to being able to reliably block, it is possible to accurately determine that an illegal act by using an illegal member has been performed.

  Since the gaming machine of the present invention is provided with a fraudulent member detection device for detecting the opening / closing operation of the subplate performed when the fraudulent member is used at a position facing the subplate of the medal selector provided inside the gaming machine, It is possible to reliably prevent fraudulent acts aimed at the malfunction of the medal count by the member.

  In a normal state, the sub plate 130 is pressed against the base plate part 110 by the elasticity of the torsion coil spring 133 wound around the shaft part 132 fixed to the base plate part 110, and a guide allowing passage of medals. Functions as a board.

  On the other hand, for example, when a medal clogging occurs in the medal selector 100, the sub-plate 130 is twisted against the elasticity of the coil spring 133 by operating (pressing) the medal return button 12a (FIG. 1). The medals jammed by the opening of the sub plate 130 can be discharged into the cancel shooter 140 (FIG. 3).

  As described above, the medals discharged into the cancel shooter 140 are returned from the medal payout port 20 (FIG. 1) through the cancel chute 300. Further, on the downstream side of the medal rail 111, a medal counting sensor 120 that counts (counts) the number of regular medals is provided.

  The medal counting sensor 120 (double reflection type photosensor) includes a pair of light emitting elements 120a and a light receiving element 120b. The medal counting sensor 120 irradiates the medal with light from the light emitting element 120a and receives reflected light reflected from the medal. By receiving light by the element 120b, a function of counting medals (counting the number of medals) is provided. In this embodiment, as described above, when the unauthorized member detection device 200 detects the insertion of the unauthorized member 121, the medal counting by the medal counting sensor 120 becomes invalid.

  In addition, a rectangular cutout portion 104 is formed on the upstream side of the medal rail 111, and an unauthorized member detection device for detecting that the unauthorized member 121 is inserted at the position of the cutout portion 104. 200 is arranged.

  In addition, a pair of support arm portions 115 and an error state detection sensor 150 for detecting the rotation of the passage shielding member 210 are located on the upper side of the back surface portion (FIG. 5) of the base plate portion 110 of the medal selector 100. Mounting is fixed. Further, the unauthorized member detection device 200 is rotatably attached to the pair of support arm portions 115.

  Here, with reference to FIG. 6 together with FIG. 5, the configuration of the unauthorized member detection apparatus 200 will be described. FIG. 6 shows a perspective view of the overall configuration of the unauthorized member detection apparatus 200. That is, as shown in FIG. 6, the unauthorized member detection apparatus 200 is configured by a passage shielding member 210 that is substantially L-shaped and formed in a wide rectangular shape, and a base end portion of the passage shielding member 210. And a rotating plate 220 bent at approximately 90 degrees.

  Among these, the rotation plate part 220 includes a pair of flat plate parts 230 and 240 and a hollow cylindrical rotation shaft part 250 sandwiched between the pair of flat plate parts 230 and 240. Moreover, the detection piece 235 extended toward the inner side is provided on one flat plate portion 230 of the pair of flat plate portions 230 and 240. Based on the rotation angle of the detection piece 235, the output level of the error state detection sensor 150 provided on the back surface portion (FIG. 5) of the base plate portion 110 changes to either ON / OFF level.

  More specifically, the position of the detection piece 235 provided on the flat plate portion 230 of the unauthorized member detection device 200 is displaced based on the bias angle of the passage shielding member 210. For example, the detection piece 235 When 235 shields the detection unit of the error state detection sensor 150 (see FIG. 7), the output of the error state detection sensor 150 is OFF.

  On the other hand, when the detection piece 235 is separated from the detection unit of the error state detection sensor 150 (see FIG. 9), the output of the error state detection sensor 150 is turned on. The error state is activated by transmission of an error detection signal for invalidating.

  That is, in this embodiment, when the output of the error state detection sensor 150 changes from OFF to ON and the ON state continues for a predetermined time, the sub plate 130 is intentionally opened to use the unauthorized member 121. Determine.

  Further, the rotation shaft 252 (FIG. 5) is inserted into the insertion hole 251 formed in the rotation shaft portion 250, and the rotation shaft 252 is formed on the back surface portion (FIG. 5) of the base plate portion 110. The support arm 115 is fixedly supported to be rotatable. Thereby, the passage shielding member 210 can be rotated at a predetermined angle around the rotation shaft 252.

  Further, a torsion coil spring 133 (torsion spring) is wound around the rotation shaft 252, and the passage shielding member 210 is always pressed toward the sub-plate 130 by the pressing force of the torsion coil spring 133. Has been. The pressing force of the torsion coil spring 133 is set to a relatively small value. Specifically, the pressing force is set so as to be pressed by a medal passing on the medal rail 111.

  Next, the details of the function of the unauthorized member detection apparatus 200 will be described with reference to FIG. FIG. 7 is a cross-sectional view of a main part of the medal selector 100 in which the unauthorized member detection device 200 is provided. Specifically, a state in which no medal is inserted from the medal insertion slot 12 (a state in which no medal is passed and before the medal is inserted) and a state in which the unauthorized member 121 is not used (an uninserted state) are shown. In the following description, the state of the medal selector 100 shown in FIG. 7 is referred to as “normal state”.

  That is, as shown in FIG. 7, when the sub-plate 130 is closed (when there is no operation by the medal return button 12 a), the passage shielding member 210 constituting the unauthorized member detecting device 200 is cut off on the medal rail 111. In a state where it protrudes from the notch 104, it stops in a state of being biased by a predetermined angle (about 15 degrees) toward the inner surface 134 of the sub-plate 130 by the pressing force of the torsion coil spring 133 (FIG. 5).

  In this case, as shown in the figure, the tip end portion 211 of the passage shielding member 210 is in contact with the inner surface portion 134 of the sub-plate 130, so that the passage from the upstream side to the downstream side of the medal rail 111 is temporarily suspended. Will be shielded.

  In this case, since the detection piece 235 of the error state detection sensor 150 shields the detection unit, the output of the error state detection sensor 150 is turned off. As described above, when the output level of the error state detection sensor 150 is OFF as described above, an error state that invalidates the medal count does not operate.

[Operation of the unauthorized member detection apparatus 200 when a medal is inserted]
Next, with reference to FIG. 8, the details of the operation of the unauthorized member detection device 200 when a medal is inserted will be described. FIG. 8 is a cross-sectional view of the main part of the operating state of the unauthorized member detection device 200 when a medal is inserted.

  That is, as shown in FIG. 8, in the normal state of the medal selector 100, when a medal inserted from the medal slot 12 (FIG. 1) passes over the medal rail 111 through the medal inlet 112, an unauthorized member is detected. The passage shielding member 210 of the device 200 is pressed by a medal that travels on the medal rail 111 from the upstream side toward the downstream side. As a result, the passage shielding member 210 rotates clockwise (from the broken line position to the solid line position) against the elasticity of the torsion coil spring 133 (FIG. 5) and is accommodated in the notch 104. As a result, the passage shielding member 210 of the unauthorized member detection device 200 can pass the medal without blocking the passage of the medal.

  At this time, similarly to the operation in the normal state, the position of the detection piece 235 of the error state detection sensor 150 is a position where the detection unit is shielded, so that the output from the error state detection sensor 150 remains OFF. Error state does not work.

  That is, when passing the medal rail 111 of the medal selector 100 inserted from the medal insertion slot 12, the passage shielding member 210 of the unauthorized member detecting device 200 allows the medal to pass and the error state does not operate. The medals determined by the medal selector 100 as regular medals are counted.

[Operation of Unauthorized Member Detection Device 200 when Inserting Unauthorized Member 121]
Next, the operation of the unauthorized member detection apparatus 200 when the unauthorized member 121 is used will be described with reference to FIG. FIG. 9 shows a cross-sectional view of the main part of the operating state of the unauthorized member detection device 200 when the unauthorized member 121 is inserted into the medal selector 100.

  That is, as shown in FIG. 9, in the medal selector 100 in the normal state, when a third party opens the sub plate 130 in the direction of the white A arrow and inserts the unauthorized member 121, the sub plate 130 is opened. The passage shielding member 210 is moved from the position in the normal state to the predetermined direction while following the movement of the sub plate 130 in the same direction (black A arrow direction) as the sub plate 130 is opened by the elasticity of the torsion coil spring 133. The angle (about 30 degrees) is biased.

  As shown in the figure, at this time, the front end portion 211 of the passage shielding member 210 and the inner surface portion 134 of the sub plate 130 come into contact with each other, so that the passage from the upstream side to the downstream side of the medal rail 111 is temporarily shielded. The Rukoto. Here, as described above, since the contact pressure by the torsion coil spring 133 is set to a relatively small contact pressure, the unauthorized member 121 includes the inner surface portion 134 of the sub-plate 130 and the distal end portion of the passage shielding member 210. 211 and the inside of the medal selector 100 (see FIG. 10-1).

  At this time, the detection piece 235 of the error state detection sensor 150 rotates to a position separated from the detection unit (a position where the detection unit is not shielded) based on the bias angle of the passage shielding member 210. The output from the sensor 150 is ON for a predetermined time. As a result, the error state due to the transmission of the error signal is activated, so that the medal count by the medal counting sensor 120 can be invalidated (the medal number is not counted).

  That is, in the case of the medal selector 100 in this embodiment, even if an operation of inserting the unauthorized member 121 with the sub plate 130 opened to avoid contact with the medal pressure 114 is performed, Since the passage shielding member 210 of the member detection device 200 is deviated by a predetermined angle as the sub-plate 130 is opened, the error state detection sensor 150 detects an error according to the deviation angle. Unauthorized acts aiming at the malfunction of medal counting due to the use of the member 121 can be reliably prevented.

[Function to prevent unauthorized member 121 from being pulled out]
Here, in addition to the function of detecting the insertion of the unauthorized member 121 by a third party, the unauthorized member detecting device 200 shown in the present embodiment has a function of preventing the unauthorized member 121 inserted into the medal selector 100 from being pulled out. It also has. Hereinafter, the pull-out prevention function by the passage shielding member 210 of the unauthorized member detection apparatus 200 will be described with reference to FIGS. Here, FIG. 10-1 is a longitudinal sectional view showing a state where the unauthorized member 121 is inserted into the medal selector 100, and FIG. 10-2 is a longitudinal sectional view showing a state where the unauthorized member is prevented from being pulled out by the passage shielding member.

  That is, as shown in FIG. 10A, the passage shielding member 210 of the unauthorized member detection device 200 is biased toward the subplate 130 with the opening of the subplate 130, and the leading end portion 211 of the passage shielding member 210 The inner surface portion 134 of the sub plate 130 comes into contact. Here, as described above, since the contact pressure by the torsion coil spring 133 that biases and presses the passage shielding member 210 toward the sub-plate 130 is set to a relatively small contact pressure, it is inserted into the medal selector 100. The illegal member 121 thus made can travel from the upstream side to the downstream side of the medal rail 111 through the space between the inner surface part 134 of the sub-plate 130 and the front end part 211 of the passage shielding member 210.

  On the other hand, as shown in FIG. 10B, when the unauthorized member 121 once inserted into the medal selector 100 is to be pulled out from the medal selector 100, in this state, the passage shielding member 210 of the unauthorized member detecting device 200 is used. Is biased toward the sub-plate 130 side, and the tip end portion 211 of the passage shielding member 210 and the inner surface portion 134 of the sub-plate 130 are in contact with each other. For this reason, even if the unauthorized member 121 inserted into the medal selector 100 is to be pulled out from the downstream side of the medal rail 111 toward the upstream side, the stepped portion of the distal end portion 124 of the unauthorized member 121 and the passage shielding member 210. The front end portion 211 of each other abuts. Thereby, as shown in the figure, the unauthorized member 121 can be prevented from being pulled out from the inside of the medal selector 100.

  As described above, the passage shielding member 210 is a passage that is biased by the opening operation of the sub plate 130 even when the unauthorized member 121 once inserted into the medal selector 100 is to be pulled out from the inside of the medal selector 100. The fraudulent member 121 collides with the distal end portion 211 of the shielding member 210, so that it is possible to reliably prevent the fraudulent member 121 from being pulled out, and that the fraudulent act by using the fraudulent member 121 has been performed. It can be judged accurately.

  Here, the distal end portion 211 of the passage shielding member 210 shown in FIG. 10-2 is not particularly provided with a blocking portion for preventing the backward operation of the unauthorized member 121, but the unauthorized member 121 is disposed at the distal end portion 211. A blocking portion that engages with a stepped portion of the tip end portion 124 (FIG. 16) may be provided. In this case, the unauthorized member 121 that moves backward from the downstream side of the medal rail 111 toward the upstream side is provided on the passage shielding member 210. Since the engaging portion is engaged with the formed blocking portion and the movement is blocked by the blocking portion, the unauthorized member 121 can be reliably prevented from being pulled out.

[Electric Configuration of Pachislot Machine 1: Main Control Circuit 71]
Next, the electrical configuration of the pachislot machine 1 shown in FIG. 1 will be described with reference to FIG.

The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program, a RAM 32 that is a storage unit, and a ROM 33.

  Connected to the CPU 31 are a clock pulse generator 34 and a frequency divider 35 for generating a reference clock pulse, and a random number generator 36 and a sampling circuit 37 for generating a random number to be sampled.

  The random number generator 36 generates random numbers belonging to a certain numerical range, and the sampling circuit 37 samples the random numbers at an appropriate timing after the start lever 17 is operated. By using the random numbers sampled in this way, for example, an internal winning combination is determined based on a probability lottery table stored in the ROM 33. Note that random number sampling can be performed by software by executing a random number sampling program on the CPU 31 in the microcomputer 30. In this case, the random number generator 36 and the sampling circuit 37 can be omitted.

  The ROM 33 of the microcomputer 30 stores various control commands to be transmitted to the sub-control circuit 72 and a probability lottery table used for determination of random number sampling performed every time the start lever 17 is operated (start operation) and a winning symbol for stopping. A determination table, a stop table group for determining a reel stop mode according to the operation of the stop buttons 18L, 18C, and 18R, and the like are stored. Note that the sub control circuit 72 does not input a control command, information, or the like to the main control circuit 71, and communication is performed in one direction from the main control circuit 71 to the sub control circuit 72.

  Further, in this ROM 33, a combination of various symbols corresponding to the display combination, the number of medal dividends, and a winning combination determination code (establishment determination code) indicating the winning (establishment) are associated with the display combination specification. The table is stored. This display combination specifying table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are stopped and when the display combination is confirmed after all the reels 3L, 3C, and 3R are stopped. The display combination (display combination data) is a combination (established combination) corresponding to a combination of symbols arranged along the active line, and the player is given a profit corresponding to the display combination. Further, the RAM 32 stores various information such as an internal winning combination, a carryover combination, and a current game state related to winning of the pachislot machine 1.

  The main actuators whose operation is controlled by a control signal from the microcomputer 30 include a BET lamp (1-BET lamp 7a, 2-BET lamp 7b, 3-BET lamp 7c), bonus number display section 8, credit display. A display unit such as a unit 9 and a payout number display unit 10, a medal hopper 21 (including a drive unit for payout) that stores medals and pays out a predetermined number of medals according to a command from the hopper drive circuit 46, a reel 3L, There are stepping motors 49L, 49C, 49R that rotationally drive 3C, 3R.

  In addition, a motor drive circuit 50 that drives and controls the stepping motors 49L, 49C, and 49R, a hopper drive circuit 46 that drives and controls the medal hopper 21, a BET lamp (1-BET lamp 7a, 2-BET lamp 7b, and 3-BET lamp 7c And a display unit driving circuit 48 for driving and controlling display units such as a bonus number display unit 8, a credit display unit 9, and a payout number display unit 10 are connected to the output unit of the CPU 31. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator.

  The microcomputer 30 also receives input signals from the start switch 17S, BET switch (1-BET switch 13S, 2-BET switch 14S, 3-BET switch 15S), reel position detection circuit 49, and payout completion signal circuit 47. Based on these, a control command is generated.

  The start switch 17S is a switch that detects an operation of the start lever 17. The BET switches 13S, 14S, and 15S are provided on the back side of the 1-BET button 13, the 2-BET button 14, and the 3-BET button 15, and the 1-BET button 13, the 2-BET button 14, and the 3-BET button 15 are provided. A switch that generates a signal in response to an operation.

  The C / P switch 16 </ b> S is a switch that is provided on the rear surface of the C / P button 16 and generates a signal in response to an operation of the C / P button 16. The reel position detection circuit 49 is a circuit that receives a pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 47 generates a signal indicating completion of medal payout when the number of medals paid out from the medal hopper 21 reaches the designated number data.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 32. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 49. The count value of the drive pulse counted in the RAM 32 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 32 stores a count value corresponding to the rotational position within one rotation range for each of the reels 3L, 3C, 3R.

  A symbol table (not shown) is stored in the ROM 33 in order to associate the rotational positions of the reels 3L, 3C, 3R as described above with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated, and a corresponding code number are provided. Is associated with a symbol code indicating the displayed symbol.

  When the CPU 31 determines the internal winning combination or the stop winning combination by lottery processing (probability lottery processing or the like) based on the random number sampling, the stop switch 18LS, 18L, 18C, 18R is operated at the timing when the player operates the stop button 18L, 18C, 18R. Based on the operation signal sent from 18CS and 18RS and the determined stop table, a signal for controlling the stop of the reels 3L, 3C and 3R is sent to the motor drive circuit 50. However, when receiving an input of a command by the player, the CPU 31 sends a signal for controlling the reels 3L, 3C, 3R to stop the motor drive circuit 50 even if the player operates the stop buttons 18L, 18C, 18R. Do not send.

  Further, when the CPU 31 is in a stop mode (that is, a winning mode) indicating winning of the winning combination, the CPU 31 supplies a payout command signal to the hopper driving circuit 46 and pays out a predetermined number of medals from the medal hopper 21. The payout completion signal circuit 47 generates a signal for detecting a medal payout completion signal when the count value of the medal detection unit 21S (the number of medals paid out from the medal hopper 21) reaches the designated number data. To do. That is, the medal detection unit 21S counts the number of medals to be paid out from the medal hopper 21 and outputs a medal payout completion signal to the CPU 31 via the payout completion signal circuit 47 when the counted value reaches a designated number. Is input. As a result, the CPU 31 stops driving the medal hopper 21 via the hopper driving circuit 46 and ends the medal payout process. The sub-control circuit 72 has a function of controlling game effects including image display, lamp display, and audio output. Specifically, the liquid crystal display unit 2b, speakers 6L and 6R, and various LEDs and lamps are controlled based on a control command transmitted from the main control circuit 71.
