JP 2003-275382 A Japanese Patent No. 4279716

  As described in Japanese Patent Application Laid-Open No. 2004-228561, the one that prevents illegal acts using a thread medal is generally one that protrudes into the medal passage after passing the medal and prevents reverse movement of the medal. Since the outer shape of the medals is circular, the medals that are lifted up with respect to the members projecting into the medal path are in a state of being locked with the uppermost ends being point-contacted. For this reason, when the medal is pulled up strongly, the lock is released and the medal may be pulled out. If an attempt is made to simply improve the locking force, the structure tends to be complicated, and the smooth insertion of medals may be impaired.

  An object of the present invention is to suppress the raising of medals more strongly without impairing the smooth insertion of medals with a relatively simple configuration.

  According to the present invention, in the medal selector that forms a medal passage through which the inserted medal passes and detects the passage of the medal, the movable member provided to be movable forward and backward in the thickness direction of the medal passage, and the medal passage An urging member that urges the movable member in a direction to enter the medals path, and the downstream end of the movable member is at both ends in the width direction of the medal path rather than the center part in the width direction of the medal path. There is provided a medal selector characterized in that at least one end portion of the portions has a shape protruding to the downstream side.

  According to the present invention, it is possible to suppress the pulling up of the medal more strongly without impairing the smooth insertion of the medal with a relatively simple configuration.

<Pattern arrangement>
A symbol arrangement applied to each of the reels 110 to 112 will be described with reference to FIG. This figure is a diagram in which the arrangement of symbols applied to each reel (left reel 110, middle reel 111, right reel 112) is developed in a plane.

  In each reel 110 to 112, a plurality of types (eight types in this embodiment) of symbols shown on the right side of the figure are arranged in a predetermined number of frames (21 frames of numbers 0 to 20 in this embodiment). Also, numbers 0 to 20 shown at the left end of the figure are numbers indicating the arrangement positions of symbols on the reels 110 to 112. For example, in the present embodiment, the “replay” symbol for the number 1 frame on the left reel 110, the “bell” symbol for the number 0 frame on the middle reel 111, and the “bell” symbol for the number 2 frame on the right reel 112. "Watermelon" design is arranged respectively.

<Type of winning prize>
Next, the types of winning combinations of the slot machine 100 will be described with reference to FIG. This figure shows the types of winning combinations (including actuating combinations), symbol combinations corresponding to each winning combination, and the operation or payout of each winning combination.

  Of the winning combinations in the present embodiment, the big bonuses (BB1, BB2) and the regular bonus (RB) are used as a combination for shifting to the bonus game, and the replay (replay) is a replay without newly inserting a medal. Each winning combination is sometimes distinguished from a winning combination and sometimes called an “acting combination”. However, in the “winning combination” in this embodiment, a big bonus, a regular bonus, and a replay that are operating combinations are included. included. In addition, “winning” in the present embodiment includes a case where a symbol combination of an actuator not accompanied by a medal payout (without medal payout) is displayed on an active line, for example, a big bonus, regular Includes bonuses and replay wins.

  The winning combination of the slot machine 100 includes a big bonus (BB1, BB2), a regular bonus (RB), a small combination (cherry, watermelon, bell), and replay (replay). Needless to say, the type of winning combination is not limited to this and can be arbitrarily adopted.

  “Big Bonus (BB1, BB2)” (hereinafter sometimes simply referred to as “BB”) is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning a prize. . Corresponding symbol combinations are “white 7-white 7-white 7” for BB1, and “blue 7-blue 7-blue 7” for BB2. Further, flag carryover is performed for BB1 and BB2. That is, when BB1 and BB2 are won internally, a flag indicating this is set (stored in a predetermined area of the RAM 308 of the main control unit 300), but even if BB1 and BB2 are not won in the game, a prize is won. Until then, the flag indicating the internal winning is maintained, and even after the next game, BB1 and BB2 are being internally selected, and the symbol combination corresponding to BB1 “white 7-white 7-white 7”, the symbol corresponding to BB2 The combination “blue 7-blue 7-blue 7” is in a state of winning a prize.

  The “regular bonus (RB)” is a special combination (operating combination) in which a regular bonus game (RB game) is started by winning. The corresponding symbol combination is “bonus-bonus-bonus”. Note that the RB carries over the flag as well as the above-mentioned BB. However, in the big bonus game (BB game) (details will be described later), the regular bonus game (RB game) is won internally and the combination of symbols is displayed on the winning line. In addition, the regular bonus game is started after the start of the big bonus game, and when the regular bonus game is finished once, the regular bonus game is automatically started so that the next regular bonus game is immediately started. It is good. “Short (cherry, watermelon, bell)” (hereinafter, simply referred to as “cherry”, “watermelon”, “bell”) is a winning combination in which a predetermined number of medals are paid out by winning. The symbol combinations are “cherry-ANY-ANY” for cherry, “watermelon-watermelon-watermelon” for watermelon, and “bell-bell-bell” for bell. The corresponding payout number is as shown in FIG. In the case of “cherry-ANY-ANY”, the symbol of the left reel 110 may be “cherry”, and the symbol of the middle reel 111 and the right reel 112 may be any symbol.

  “Replay” is a winning combination (operating combination) in which a game can be performed without inserting a medal (game medium) in the next game by winning, and no medal is paid out. The corresponding symbol combination is “replay-replay-replay” for replay.

<Type of gaming state>
Next, the types of gaming state of the slot machine 100 will be described. In this embodiment, the gaming state of the slot machine 100 is roughly divided into a normal game, a BB game, an RB game, and an internal winning game of a big bonus (BB) and a regular bonus (RB). However, it may be divided into a general game, a BB game, and an RB game.

<Normal game>
The winning combinations that are internally won for normal games include a big bonus (BB), regular bonus (RB), replay (replay), and small roles (cherry, watermelon, bell). “Big Bonus (BB)” is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning. “Regular Bonus (RB)” is a special combination (operating combination) that starts a regular bonus game (RB game) upon winning. The “replay” (replay) is a winning combination (operating combination) in which a game can be performed without a medal being inserted in the next game by winning, and no medal is paid out. The “small role” is a winning combination in which a predetermined number of medals are paid out by winning.

  In addition, the internal winning probability of each combination is a range of random values obtained at the time of internal lottery from numerical data corresponding to the range of lottery data associated with each combination from lottery data prepared for normal games. It is calculated by the value divided by the numerical data (for example, 65535). The lottery data prepared for the normal game is divided into several numerical ranges in advance, and each combination and lose is associated with each numerical range. It is determined whether the random number value obtained as a result of executing the internal lottery is a value corresponding to the lottery data corresponding to which combination, and the internal lottery combination is determined. This lottery data is provided with settings 1 to 6 in which the winning probabilities of at least one combination are different, and a game shop clerk can arbitrarily select and set any set value.

  In normal games, the result of the internal lottery is set to be largely lost (big bonus (BB), regular bonus (RB), replay (replay) and small role won), and the medal to be won The total number is less than the total number of medals inserted. Therefore, it is a gaming state that is disadvantageous for the player. However, when a predetermined condition is satisfied (for example, when a specific symbol combination is displayed), it is a gaming state that may be changed to increase the probability of internal winning of replaying. In this case, When a predetermined number of medals are paid out by winning a small role, there are cases where the total number of medals to be acquired exceeds the total number of medals inserted, resulting in a gaming state that is beneficial to the player.

<BB game>
The BB game is set to be in a gaming state that is beneficial to the player. That is, the BB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the BB game is started by winning a big bonus (BB), and an RB game (described later) can be continuously executed repeatedly, and a predetermined number (for example, during the game) The process ends when more than 465 medals are obtained. However, the BB game does not allow the RB game to be executed continuously and repeatedly, and sets the role to start the RB game (the symbol combination is, for example, replay-replay-replay), and if this role is won internally, or The RB game may be set to start when winning. Furthermore, in the BB game, when the BB general game excluding the RB game during the BB game is executed a predetermined number of times (for example, 30 times), or the number of the RB games executed during the BB game is a predetermined number of times. It may be made to end when it reaches (for example, three times).

<RB game>
The RB game is set so as to be in a gaming state that is beneficial to the player. That is, the RB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the RB game is started by winning a regular bonus (RB), and one predetermined role is set to a variation that increases the probability of internal winning (for example, “setting 1” “normal game”). Increase the internal winning probability 1/15 of “small role 1” to an internal winning probability 1 / 1.2 which is a predetermined value) and win a predetermined number (for example, 8 times) It ends when there is. A BB game ends when a predetermined number of wins are made (for example, 8 times) or when the number of RB games executed during the RB game reaches a predetermined number of times (for example, 8 times). You may make it do.

<Big winning (BB) and regular bonus (RB) internal winning games>
The winning combination that is internally won for the internal winning game of the big bonus (BB) and the regular bonus (RB) includes a replay and a small role. The big bonus (BB) and the regular bonus (RB) are not won internally, and are game states in which a symbol combination corresponding to the big bonus (BB) or the regular bonus (RB) can be won.

  However, the probability of the internal winning of the replay may be changed from the next game that has been internally won to the big bonus (BB) and the regular bonus (RB), for example, the probability of increasing the internal winning probability of the replay is changed. Until the symbol combination corresponding to the big bonus (BB) and regular bonus (RB) wins, the total number of medals to be acquired is almost the same as the total number of inserted medals, and is compared with the normal game. The gaming state may be beneficial to the player.

<Main control unit main processing>
A main control unit main process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit. As described above, the main control unit 300 is provided with the start signal output circuit (reset signal output circuit) 338 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input starts reset by a reset interrupt and executes the main process of the main control unit shown in FIG. 4 according to the control program stored in advance in the ROM 306.

  When the power is turned on, first, various initial settings are performed in S1. In this initial setting, setting of the stack initial value to the stack pointer (SP) of the CPU 304, setting of interrupt inhibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, operation permission to the WDT 313, and initial setting Set the value.

  In S2, a medal insertion / start operation acceptance process is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 is turned on in response to the insertion of the medal. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. Further, it is checked whether or not the start lever 135 has been operated. If there is an operation of the start lever 135, the process proceeds to S3.

  In S3, the number of inserted medals is determined and an effective winning line is determined. In S4, the random number generated by the random number generation circuit 316 is acquired. In S5, the winning combination lottery table stored in the ROM 306 is read according to the current gaming state, and an internal lottery is performed using this and the random value acquired in S4. As a result of the internal lottery, when any winning combination is won internally, the internal winning flag of the winning combination is turned ON. In S6, reel stop data is selected based on the internal lottery result.

  In S7, rotation of all reels 110 to 112 is started. In S8, the stop buttons 137 to 139 can be received. When any of the stop buttons is pressed, any of the reels 110 to 112 corresponding to the pressed stop button is selected as the reel stop control data selected in S6. Stop based on. The reel stop control basically allows the combination of symbols corresponding to the winning combination to be displayed when there is an internal winning winning combination, and the symbol corresponding to any combination in the case of a loss, etc. Reel stop control such as so-called pull-in and kick-out is performed so that combinations are not displayed.

  When all the reels 110 to 112 are stopped, the process proceeds to S9. In S9, a winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “bell-bell-bell” is aligned on the activated winning line, it is determined that the player has won the bell. Also, the internal winning flag is reset unless the flag is carried over.

  In S10, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out according to the number of winning lines. In S11, a game state control process is performed. In the game state control process, a process related to transition of each game state of normal game, BB game, RB game, and internal winning game is performed, and the game state is shifted when those start conditions and end conditions are satisfied. Thus, in this embodiment, a privilege is given to the player based on the combination of symbols that are stopped and displayed. Thus, one game is completed. Thereafter, the game proceeds by returning to S2 and repeating the above-described processing.

<Medal selector>
Next, the medal selector 200 attached to the back surface of the front door 102 will be described. 5 is a perspective view of the medal selector 200, FIG. 6 is an exploded perspective view of the medal selector 200, and FIG. 7 is a front view of the medal selector 200 with the front cover 230 removed. The medal selector 200 forms a medal passage through which medals inserted from the medal insertion slot 141 pass while rolling, and drops a medal having a diameter smaller than that of the regular medal to one side of the medal passage. And detect the passage of regular medals. The upstream side and the downstream side are based on the direction in which the medals flow while rolling, and the medal slot 141 side is the upstream side.

  The medal selector 200 includes a selector base 210, a guide member 220, a front cover 230, an actuator 250, a medal detection sensor 260, a movable member 270, an urging member 280, and an operation detection sensor 290. The medals inserted into the medal insertion slot 141 are first introduced into the introduction port 201 formed by the selector base 210 and the guide member 220 and discharged from the discharge port 215 formed in the selector base 210.

  The selector base 210 includes a passage wall 211. The passage wall 211 forms one of the passage walls facing the side surface among the side surface and the peripheral surface of the passing medal. The passage wall 211 includes a plurality of ribs 211a that are separated from each other in the width direction of the medal passage and extend in the medal passage direction, and a plurality of slits 211b that are separated from each other in the width direction of the medal passage and extend in the medal passage direction. , Is formed. The slit 211b is formed between the ribs 211a. By providing the rib 211a, the area in contact with the side surface of the passing medal is reduced, and the medal can be moved more smoothly.

  On the downstream side of the passage wall 211, a bottom portion BT and a contact portion 214 of the medal passage are formed. The peripheral surface of the medal is in contact with the bottom portion BT while rolling, and the contact portion 214 is in contact with the side surface of the medal. A part of the bottom portion BT is formed by the movable bottom portion 212. The movable bottom 212 is movable to a position displaced from the other part of the bottom BT by a movable mechanism (not shown) provided in the selector base 210, and is driven by the actuator 250 to operate when a medal insertion is prohibited. Make up a medal blocker.

  That is, when the medal insertion is prohibited, the movable bottom 212 is moved by the operation of the actuator 250, thereby making the bottom BT partially discontinuous, and the medal rolling on the bottom BT is placed on one side of the medal path. It drops off to the front cover 230 side. As a configuration of the medal blocker, in addition to a configuration in which a part of the components of the medal passage is movable as described above, a member that moves in and out from the side of the medal passage may be driven by an actuator.

  The abutting portion 214 protrudes from the front side of the selector base 210 and is formed in the medal flow direction, and forms a slit for preventing a regular medal from dropping out together with a guide member 220 described later. The selector base 210 includes a pair of bearing portions 213 having a hook shape. A shaft 240 is detachably attached to the bearing portion 213. The discharge port 215 is formed at the downstream end of the bottom BT, and medals passing through the medal selector 200 are discharged from the discharge port 215 and guided to a hopper device (not shown) for storing medals by a guide member (not shown). Will be.

  The actuator 250 is an actuator having an electromagnetic solenoid, and is attached to the back side of the selector base 210. The medal detection sensor 260 is an optical sensor that is supported by the selector base 210 and detects the passage of a medal that passes through the slit 261, but sensors other than the optical sensor can be used. In the present embodiment, the medal detection sensors 260 are disposed relatively upstream and downstream, respectively, and normal insertion of medals is determined based on the detection results of the two medal detection sensors 260. Note that electrical wiring is connected to the connector 262.

  Next, the front cover 230 will be described with reference to FIGS. FIGS. 8A and 8B are perspective views of the front cover 230. The front cover 230 includes a passage wall 231 that faces the passage wall 211 of the selector base 210. The passage walls 211 and 231 form a passage wall that is separated in the thickness direction of the medal passage, and the medal passes between them. The passage wall 231 is also formed with a plurality of ribs 231a that are separated from each other in the width direction of the medal passage and extend in the medal passage direction, thereby reducing friction with the medal.

  The front cover 230 has a pair of fitting portions 232 into which both end portions of the shaft 240 are fitted. The shaft 240 is loaded with a spring 241, and the front cover 230 is attached to the selector base 210 by attaching the shaft 240 to the bearing portion 213 in a state where the shaft 240 is fitted to the fitting portion 232. Can do. When attached to the selector base 210, the front cover 230 can be opened and closed around the shaft 240, but is always urged in the closing direction by a spring 241.

  A knob portion 234 is formed on the front side of the front cover 230. By using the knob portion 234, the opening / closing operation of the front cover 230 and the attaching / detaching operation to / from the selector base 210 can be facilitated. The front cover 230 also includes a cover portion 233 that covers the medal detection sensor 260. The cover part 233 has a ceiling part 233 a that covers the front side of the medal detection sensor 260 and covers the upper surface side of the medal detection sensor 260. Since the connector 262 of the medal detection sensor 260 is covered by the ceiling portion 233a, it is possible to prevent an unauthorized instrument from entering the connector 262. In the present embodiment, the front cover 230 has the protection function of the medal detection sensor 260 in this way.

  With reference to FIGS. 6 and 7, the guide member 220 is formed by bending a metal plate, for example, and includes an attachment portion 221 and a slit formation portion 222. A plurality of attachment holes are formed in the attachment portion 221, and the guide member 220 is fixed to the selector base 210 by fitting the attachment shaft of the selector base 210 to the attachment portion 221.

  The slit forming part 222 forms a slit through which the upper part of the regular medal passes together with the contact part 214 of the selector base 210. The slit is formed at a position spaced from the bottom BT by a distance corresponding to the diameter of the regular medal so that only a small portion of the upper part of the regular medal is inserted, and a position where a medal smaller in diameter than the regular medal is not inserted Formed.

  Therefore, the small-diameter medal is not supported by the slit forming portion 222 and the contact portion 214, but tilts to the side and falls out of the medal selector 200, so that the regular medal and the small-diameter medal are selected. The regular medal is supported by the slit forming part 222 and the contact part 214, and reaches the medal detection sensor 260, and its currency is detected.

  With reference to FIGS. 6 and 7, the movable member 270 is pivotally attached to the back side of the selector base 210. The biasing member 280 always biases the movable member 270 in one direction. In the present embodiment, the biasing member 280 is a torsion coil spring, but any member that can bias the movable member 270 may be used. The motion detection sensor 290 is an optical sensor that detects the rotational position of the movable member 270, and is a transmissive optical sensor that detects an object passing through the slit, like the medal detection sensor 260.

  9A to 9D are explanatory views of the movable member 270. FIGS. 9A and 9B are a plan view and a right side view in an attached state, and FIGS. 9C and 9D are views. It is a perspective view. The movable member 270 includes a cylindrical shaft portion 272. A shaft member (not shown) of the selector base 210 is inserted into the center hole of the shaft portion 272, and the movable member 270 is supported by the selector base 210 so as to be rotatable around the center axis of the shaft portion 272. The shaft portion 272 has a spring mounting portion 272a having a relatively small diameter, and the biasing member 280 is loaded therein.

  The movable member 270 includes advance / retreat portions 271a to 271d corresponding to the slits 211b formed in the passage wall 211. The advancing / retreating portions 271a and 271b are connected at their upstream ends to the shaft portion 272, and the advancing / retreating portions 271c and 271d are connected to the advancing / retreating portions 271a and 271b via the upstream connecting portion 273a and the downstream connecting portion 273b. Has been.

  A detection piece 274 is integrally formed with the advance / retreat portion 271d. The motion detection sensor 290 detects the rotational position of the movable member 270 by detecting the presence / absence of the detected piece 274. FIG. 10 is an explanatory diagram showing the arrangement of the detected piece 274 and the motion detection sensor 290 during assembly. The detected piece 274 is located at a position facing the slit of the motion detection sensor 290.

  Each advance / retreat portion 271a to 271d advances and retreats in the thickness direction of the medal passage through the corresponding slit 211b by the rotation of the movable member 270. In this embodiment, the advancing / retreating portions 271a to 271d are moved forward and backward by the rotational movement of the movable member 270. However, the advancing / retreating portions 271a to 271d may be advanced and retracted by the translational movement of the movable member 270.

  The urging member 280 constantly urges the movable member 270 in the direction of the arrow d1 in FIG. 9B, that is, the direction in which the advance / retreat portions 271a to 271d enter the medal passage. FIGS. 11A and 11B are explanatory diagrams of the advance / retreat mode of the advance / retreat units 271a to 271d. In the figure, the broken line L1 indicates the tip position of the rib 211a, and the broken line L2 indicates the tip position of the rib 231a.

  FIG. 11A shows a state where the medal is not passing, and shows a case where the advancing / retreating portions 271a to 271d are in the approaching state. The amount of protrusion of each of the advancing / retreating portions 271a to 271d into the medal passage with reference to the broken line L1 gradually increases from the upstream side toward the downstream side so as not to hinder the smooth passage of medals. On the other hand, the downstream ends of the advancing / retreating portions 271a to 271d are close to the broken line L2, and the interference with the passing medal is ensured. In the state where the medal shown in FIG. 11A is not passing, the detected piece 274 is located outside the slit of the motion detection sensor 290, and its presence is not detected by the motion detection sensor 290.

  FIG. 11B shows a state when a medal (not shown) is passing, and shows a case where the advancing / retreating portions 271a to 271d are in the retracted state. The amount of protrusion of each of the advancing / retreating portions 271a to 271d into the medal passage with respect to the broken line L1 is reduced, and a medal passage space is secured by being entirely separated from the broken line L2. The retreat positions of the advancing / retreating portions 271a to 271d may be positions completely removed from the medal path, but may be left in the medal path as long as the medal can pass as shown in FIG. In the state where the medal shown in FIG. 11B is passing, the detected piece 274 is positioned in the slit of the motion detection sensor 290, and its presence is detected by the motion detection sensor 290. When the motion detection sensor 290 continuously detects the detected piece 274 for a specified time (for example, several tens of seconds), it is assumed that some sort of fraud (such as inserting a foreign object into the medal selector 200) has been performed. Error processing may be executed.

  Next, the shape of the downstream end portion of the movable member 270, that is, the downstream end portions of the advance / retreat portions 271a to 271d will be described with reference to FIG. FIG. 12A is an explanatory diagram of the positions of the downstream end portions of the advancing / retreating portions 271a to 271d. In the case of this embodiment, the downstream ends of the advancing / retreating portions 271a to 271d are more advanced than the advancing / retreating portions 271b and 271c at the center in the width direction of the medal passage than the advance / retreat portions 271a and 271d at both ends in the width direction of the medal passage. Protrudes downstream. The broken line P1 indicates the positions of the downstream end portions of the central advance / retreat portions 271b and 271c, and the broken line P2 indicates the positions of the downstream end portions of the advance / retreat portions 271a and 271d at both ends. For this reason, when the medal that has passed through the movable member 270 is pulled up with a hanging thread or the like, the number of the advancing / retreating portions 271a to 271d caught on the periphery of the medal increases.

  In particular, in the case of the present embodiment, the downstream end portions of the advance / retreat portions 271a and 271d project to the downstream side according to the outer shape arc shape of the medal, and the downstream end portions of the advance / retreat portions 271a to 271d match the outer shape arc shape of the medal. Because of the shape, the downstream end portions of the advancing / retreating portions 271a to 271d are hooked on the peripheral edge of the medal substantially simultaneously. For this reason, it strongly resists by raising the medal. For this reason, it is possible to suppress the raising of the medal more strongly without impairing the smooth insertion of the medal with a relatively simple configuration.

  FIG. 12B shows an example in which an advancing / retreating portion 271e having the same downstream end position (broken line P3) is used instead of the advancing / retreating portions 271a to 271d as a comparative example. In the case of this configuration, since only the central two advancing / retreating portions 271d are caught on the periphery of the medal, it is obvious that the resistance to raising the medal is inferior.

  Next, a series of operation modes of the movable member 270 when the medal passes will be described. FIG. 13 and FIG. 14 are explanatory diagrams of operation modes of the movable member 270. FIG. 13A shows a state where the medal M is being introduced into the introduction port 201. In this case, the advance / retreat parts 271a to 271d are in the approach state. FIGS. 13B and 13C and FIGS. 14A and 14B show a mode in which the medal M passes over the advancing / retreating portions 271a to 271d. The movable member 270 rotates in the direction opposite to the arrow d1 in FIG. 9B due to the weight of the medal M against the urging of the urging member 280, and the advance / retreat portions 271a to 271d are displaced to the retracted state.

  When the medal M passes over the advancing / retreating portions 271a to 271d, a frictional resistance acts on the medal M from the advancing / retreating portions 271a to 271d, so that the medal M can also be decelerated, and the medal M can move while moving wildly. Can be prevented. In particular, since the advancing / retreating portions 271a and 271d are long in the medal passing direction, the decelerating effect of the medal M can be improved.

  When the medal M finishes passing over the advancing / retreating portions 271a to 271d, the advancing / retreating portions 271a to 271d are returned to the entering state as shown in FIG. Thereafter, even if the medal M is to be pulled up with a hanging thread or the like, the resistance is received by the advancing / retreating portions 271a to 271d as described above.

Second Embodiment
In the first embodiment, the downstream end portions of both the advancing / retreating portions 271a and 271d located at both ends in the width direction of the medal passage are configured to protrude downstream, but either one may be used. FIG. 15A is a perspective view showing another example of the movable member 270, and FIG. 15B is an explanatory diagram of the positions of the downstream end portions of the advance / retreat portions 271a to 271d ′. In the example shown in the figure, the advancing / retreating portion 271d ′ has the same position of the downstream side end portion as the advancing / retreating portions 271b and 271c on the center side, and only the advancing / retreating portion 271a projects its downstream end portion to the downstream side. Even in this configuration, since the three advancing / retreating portions 271a to 271c are caught on the medal periphery, they are more strongly resisted by raising the medal than the example shown in FIG.

<Third Embodiment>
In the first embodiment, the amount of protrusion of the advance / retreat portions 271a to 271d into the medal passage is made uniform along the medal passage direction (FIG. 11A), but may be different. FIG. 15C shows an example in which the protruding amount is changed.

  In the example of the figure, the amount of protrusion into the medal passage is made uniform by the set of the advance / retreat portions 271a and 271d, and the amount of protrusion into the medal passage is made uniform by the set of the advance / retreat portions 271b and 271c on the center side in the width direction of the medal passage. It is said. The set of advance / retreat portions 271b and 271c has a smaller amount of protrusion in the upstream portion UP than the set of advance / retreat portions 271a and 271d. In the upstream portion UP, the medal path in the set of advance / retreat portions 271b and 271c. The shape is recessed in the thickness direction.

  Since the medals are circular, when the medals reach the advancing / retreating portions 271a to 271d, the protruding amounts of the advancing / retreating portions 271a to 271d into the medal passage are set along the passing direction of the medals as in the first embodiment. If uniform, first, the advancing / retreating portions 271b and 271c on the center side interfere with medals (see FIG. 13B). For this reason, the upstream portions of the advance / retreat portions 271b and 271c are subject to uneven wear.

  As in this embodiment, the advancing / retreating portions 271b and 271c initially interfere with the medal by reducing the amount of protrusion in the upstream portion UP compared to the advancing / retreating portions 271a and 271d. In other words, since the all-advancing / retreating portions 271a to 271d interfere with the medal substantially at the same time, uneven wear can be prevented and the durability of the movable member 270 can be improved.

  Next, in the example of FIG. 15C, the set of advance / retreat portions 271b and 271c has the same protrusion amount at the downstream end portion as the downstream end portions of the advance / retreat portions 271a and 271d. Thereby, when the medal is not passed, the medal passage can be closed almost completely only by the set of the advancing / retreating portions 271b and 271c.

  In the example of FIG. 15C, the protrusion amounts of both the upstream portion UP and the downstream end portion of the advance / retreat portions 271b and 271c are changed, but it goes without saying that either one may be used. Moreover, this embodiment can also be combined with the second embodiment.

<Fourth embodiment>
In the first embodiment, the advancing / retreating portions 271a to 271d are integrally formed, but may be configured separately and configured to be individually rotatable. FIG. 16A shows an example in which the movable member 270 is configured separately by providing a shaft portion 272b for each of the advance / retreat portions 271a to 271d. By configuring the advance / retreat parts 271a to 271d in this manner, even if some advance / retreat parts are moved to the retracted position by an illegal act, the remaining advance / retreat parts are still located at the entry position. There is an advantage that the medal passage can be closed.

  When the advancing / retreating portions 271a to 271d are configured separately as in the present embodiment, the urging member 280 is required for each of the advancing / retreating portions 271a to 271d, but the integral molding having an urging portion for each of the advancing / retreating portions 271a to 271d. Parts may be used. FIG. 16B shows an urging member 281 that replaces the urging member 280. The urging member 281 is integrally formed by an elastic member such as a leaf spring, and has urging portions 281a to 281d for the advance / retreat portions 271a to 271d, respectively, which urge the advance / retreat portions 271a to 271d individually.

  Next, the advancing / retreating portions 271a to 271d may be configured to be rotatable for each group. In the example of FIG. 16C, the movable member 270 is provided with a common shaft portion 272c for each of the sets of the advance / retreat portions 271a and 271b and the set of the advance / retreat portions 271c and 271d. Rotate. In the example of FIG. 16D, the movable member 270 is provided with common shaft portions 272d and 272e for the set of advance / retreat portions 271a and 271d and the set of advance / retreat portions 271b and 271c, respectively. Rotate each set.

  This embodiment can be combined with the second and third embodiments.

<Fifth Embodiment>
In the first embodiment, the advancing / retreating portions 271a to 271d separated in the width direction of the medal passage advance and retreat into the medal passage. However, a configuration including an advancing / retreating portion continuous in the width direction may be used. The example of the movable member 270 in FIG. 16E has a configuration in which an advance / retreat portion 271e is connected to the shaft portion 272f, and rotates around the central axis of the shaft portion 272f. The advancing / retreating portion 271e is a single member that is continuous in the width direction of the medal passage, and its downstream side end portion is configured such that both end portions in the width direction of the medal passage protrude downstream in accordance with the outer diameter arc shape of the medal. .

  In this example, the passage wall 211 is formed with an opening through which the advance / retreat portion 271e can advance and retreat instead of the slit 211b. This embodiment can be combined with the second and third embodiments.

<Other application examples>
In each of the embodiments described above, the prevention of the lifting of the thread hanging medal is targeted, but the present invention can also be applied to the prevention of the lifting of the thread hanging game ball (pachinko ball). FIG. 17A is an explanatory diagram of the positions of the downstream end portions of the advancing / retreating portions 271a to 271d of the movable member 270, and also has an arc shape according to the outer diameter of the game ball P. FIG. 17 (b) shows an example of an illegal act of the hanging game ball P with respect to the electric tulip D, and shows an illegal act of moving the game ball P up and down to enter and retreat the electric tulip D. By arranging the movable member 270 on the upstream side of the sensor that detects the entry of the game ball P in the path of the game ball P in the electric tulip D, for example, such an illegal act can be prevented.
