Description

  The present invention relates to a pachinko machine that uses a game ball to play a game.

  In general, a pachinko machine launches a game ball supplied from a storage tray provided on the front surface of a device main body toward a game area of a game board by a launching device, and the game ball is provided in a prize opening ( When entering the starting prize opening or the general prize opening), a predetermined number of game balls are paid out to the storage tray as prize balls. The game board is provided with an outer rail that guides a game ball launched by the launching device to the upper side of the game area, and an inner rail that defines most of the peripheral wall of the game area. The space between the rails is the launch guide passage. The launching device is driven by a turning operation of a launching handle provided in the lower front portion of the apparatus main body, and a launching rail that is inclined toward the launching guide passage is provided in the vicinity of the launching device. A launch standby position for holding a game ball supplied from a storage tray is formed on the launch rail, and a rail missing portion is formed between the launch guide passage and the launch rail.

  When the player turns the launch handle to an arbitrary angle, the game ball supplied from the storage tray to the launch standby position on the launch rail is hit by the hammer of the launcher. It jumps over the missing part and heads for the game basin from the launch guide passage. At that time, the game ball that could not reach the game area due to insufficient momentum at the time of launching travels backward through the launch guide passage and falls to the rail missing portion, and then fouls through the recovery passage continuous to the rail missing portion. Returned to the player as a ball. On the other hand, a sufficiently strong game ball passes through the launch guide passage and enters the game area. When the game ball flows down the game area and enters the winning opening, as described above, a predetermined number of game balls are entered. The ball is paid out to the storage tray as a prize ball. Here, a detection sensor such as a proximity switch is arranged inside the winning opening, and usually one detecting sensor is arranged for one winning opening. The detection sensor is switched on / off by the passing of the game ball, and the game ball that has entered the winning opening passes through the detecting sensor, and is preset according to the type of winning opening (start winning opening or general winning opening). A predetermined number of game balls are paid out to the storage tray as prize balls.

  Conventionally, as a goto action in such a pachinko machine, a piano wire or the like has been inserted into the game area from the gap of the device body, and whether the game ball has entered a special area called a prize opening or V zone using this piano line As described above, the malfunction of the detection sensor causes illegal acts such as illegally exploiting a prize ball or acquiring a jackpot game. Therefore, two detection sensors are stacked in the vertical direction inside one winning opening, and only when the game balls are detected by the two detection sensors in order from the upper side to the lower side within a predetermined time, There has been proposed a pachinko machine equipped with a game ball passage recognition means for recognizing that a ball has been properly entered in a winning opening (see, for example, Patent Document 1). According to the pachinko machine equipped with such a game ball passage recognition means, a person who intends to act illegally inserts a piano wire from the gap of the device body, and uses this piano wire in the prize opening arranged in the game area. Even if it tries to stimulate the detection sensor, it usually stimulates only one of the upper and lower two detection sensors, so it is not determined that the game ball has been properly entered in the winning opening, and the game ball is paid out illegally. There is nothing. Also, even if the two detection sensors in the winning opening can be stimulated using the piano wire, the two detecting sensors move from the upper side to the lower side for a predetermined time as if the game balls actually entered the winning opening. Since it is extremely difficult to output the detection signals in order, fraudulent acts using the piano wire can be prevented.

  By the way, the trick of gotoing to illegally exploit game balls has become more sophisticated every day, for example, a ball with a thread that is glued with a transparent fishing line to the game ball is launched into the game area and this thread is attached. There is a problem of fraudulent behavior called thread goto which creates a state as if a game ball has entered by manually manipulating the ball from the outside through the storage tray and guiding it to the winning opening or the V zone. This thread goto action is to put a game ball with a thread into a prize opening or V zone and operate an internal detection sensor. By skillfully manipulating the thread, the game ball is placed near the prize entrance or the entrance of the V zone. By moving the ball up and down, it is possible to make the ball with a thread behave like a regular game ball, so that the conventional pachinko machine disclosed in Patent Document 1 prevents such a thread goto action. I couldn't.

  The present invention has been made in view of the actual situation of the prior art, and an object thereof is to provide a pachinko machine that can prevent an illegal act using a ball with a thread with a simple configuration.

In order to achieve the above object, the present invention provides a game board having a game area in which game balls flow down, a launch guide passage partitioned by an inner rail and an outer rail communicating with the game area, and hammering. A launch device that launches a game ball; and a ball holding unit that holds the game ball at a launch standby position near the launch device, wherein the launch device holds the game ball held at the launch standby position in the launch guide passage. In the pachinko machine in which a foul ball that is launched toward the game area through the game apparatus and is returned by the launching device without returning to the game area is led to the collection passage. An actuating member having a detecting part capable of entering and exiting a tangential line drawn from the ball holding part to the arc of the inner rail at an upper position in a space defined between the part and the firing guide passage, and the actuating member Locked in Disposed and retained obstructing body in the retracted position, by the game ball and thread are driven out into the play area through the firing guide path, the detection portion in the yarn tension passes over the tangential Is moved across the tangent line, the blocking body is released from the locked state with the actuating member and moved from the retracted position to the appearance position, so that the game ball launched from the launching device is It collides with the said blocking body in the near side rather than a discharge guide passage.

  In the pachinko machine configured in this way, the detection part of the operating member is usually at a position that is out of the launch path of the game ball, and the blocking body is held in the retracted position by being locked to the operating member. The regular game ball hit by the hammer of the launcher is launched into the game area through the launch guide passage partitioned by the inner rail and the outer rail without contacting the detecting portion of the actuating member. On the other hand, when a game ball with a thread (a ball with a thread) is supplied from the storage tray to the launch standby position and hit with a hammer of the launcher, the game ball passes through the launch guide passage with the thread attached to the game area. After passing through a fixed route defined between the firing standby position and the outer peripheral surface of the inner rail, the thread reaches the game area together with the game ball via the upper end of the launch guide passage. . In other words, when a tangent line is drawn from the ball holding portion having the firing standby position to the outer peripheral surface (arc) of the inner rail, the thread attached to the game ball always passes through this tangent line and then reaches the game area. The detecting portion of the operating member is lifted so as to cross the tangential line by the tension of the thread passing on the tangent, and accordingly, the blocking member is released from the locked state with the operating member and moves from the retracted position to the appearance position. Therefore, the game ball subsequently launched from the launching device does not reach the game area by colliding with the blocking body on the near side of the launch guide passage, and even if the threaded ball is guided to the start winning opening and the V zone Even if the jackpot gaming state can be achieved, no prize ball can be obtained during the jackpot gaming. Also, if you attempt to illegally exploit the prize ball by guiding the ball with thread to the general prize opening, if the ball with thread for the first time does not surely reach the target location in the game area, the game ball that is fired after that Since all cannot reach the game area, it is possible to suppress such fraud. In addition, since a fraudulent act using a threaded ball can be detected by mechanical parts having a simple structure, that is, an actuating member and a blocking body, it is possible to prevent the detection structure from becoming complicated and costly.

  In the above configuration, when the blocking body moves to the appearance position by using the threaded ball, the game ball launched from the launching device may collide with the blocking body and return to the firing standby position. It is preferable that the game ball that has collided with the ball is guided to the collection passage as a foul ball because the ball of the game ball can be reliably prevented.

  In the pachinko machine according to the present invention, when a game ball with a thread is launched toward the game area, the thread passes through a predetermined route between the launch standby position and the outer peripheral surface of the inner rail, thereby moving the operating member. Since the blocking body moves from the retracted position to the appearance position along with the operation, the game ball subsequently launched from the launching device cannot reach the game area. Therefore, even if the ball with a thread can be put into a jackpot game state, it is not possible to obtain a prize ball by putting the game ball into the big prize opening during the jackpot game, and the ball with a thread is used. In addition, fraudulent acts such as exploiting prize balls can be prevented, and such fraudulent acts can be detected only with the mechanical parts of the actuating member and blocking body, preventing the detection structure from becoming complicated and costly. it can.

  As shown in FIG. 4, on the left side of the game area 8 of the game board 7, an outer rail 32 that guides the game ball launched from the launch device 23 to the upper side of the game area 8, and the outer peripheral surface of the regulation rail 10 An inner rail 33 extending along the inner rail 33 is provided, and a space portion sandwiched between the outer rail 32 and the inner rail 33 is a launch guide passage 34. In FIG. 4, the variable display device 24 and the start winning ports 25 and 26 provided in the game area 8 are not shown. The outer rail 32 is arranged in an arc shape from the left position away from the out port 31 through the left end and upper end portion of the game board 7, and the upper end side of the outer rail 32 is continuous with the guide rail 9. The inner rail 33 is arranged in an arc shape from a position slightly on the left side of the outlet 31 to the upper end portion of the game board 7, and a ball return that prevents the game ball from returning from the game area 8 to the upper end portion of the firing guide passage 34. A prevention piece 35 is provided.

  In addition, the installation section 2 a below the game board 7 is provided with a launch rail 36 as a ball holding section, and this launch rail 36 is located obliquely above the launch device 23. The firing rail 36 is inclined upwardly toward the firing guide passage 34, and the lowermost portion at the right end of the inclined surface is a firing standby position 36a. A supply port 37a indicated by a two-dot chain line is disposed in the vicinity of the firing standby position 36a, and this supply port 37a is connected to the upper tray 13 and is an outlet of a rectifier 37 that protrudes toward the back side of the glass door 3. (See FIG. 2). That is, the game balls stored in the upper tray 13 are supplied one by one from the supply port 37a to the launch standby position 36a while being rectified in a line by the rectifier 37, and the game balls held at the launch standby position 36a are launched. It is fired in the direction of the firing guide passage 34 by hitting the hammer 23a of the device 23.

  In the upper part of the space S from the firing rail 36 to the firing guide passage 34, an operating member 38 operated by a threaded ball, which will be described later, a support 39 that rotatably supports the operating member 38, and an operating member 38 are provided. A blocked blocking body 40 is arranged, and the center of gravity is set so that the blocking body 40 rotates by its own weight. Further, a foul ball collection passage 41 is provided in the lower portion of the space S, and a ball collection portion 14a (FIG. 2) that protrudes from the lower tray 14 to the back side of the glass door 3 at the lowermost portion of the foul ball collection passage 41. Browse) is located.

  As shown in FIG. 5, the actuating member 38 can rotate in a plane parallel to the board surface of the game board 7 around the shaft part 39 a of the support body 39, and the support body 39 is screwed to the installation part 2 a of the main body frame 2. It is fixed using. A detecting portion 38a is formed on the front end side of the actuating member 38, and a driving portion 38b is formed on the opposite side (rear end side) through the detecting portion 38a and the shaft portion 39a. The blocking body 40 is formed with a support shaft 40a, an engagement receiving portion 40b, and a ball receiving portion 40c. By inserting the support shaft 40a into the shaft hole of the installation portion 2a, the blocking body 40 is centered on the support shaft 40a. It is possible to rotate in a plane orthogonal to the board surface of the game board 7. In the normal state, as shown in FIG. 5A, the engagement receiving portion 40b is engaged with the drive portion 38b of the actuating member 38, so that the blocking body 40 is supported by its own weight at the upper retracted position. When the operating member 38 rotates in the arrow α direction in this normal state, and the driving unit 38b moves away from the engagement receiving unit 40b, the blocking member 40 is not supported by the operating member 38 and rotates in the arrow β direction by its own weight. As shown in FIG. 5B, the blocking body 40 falls to the appearance position and causes the ball receiving portion 40c to face the launch path of the game ball.

  As shown in FIG. 6, when the tangent line M is drawn from the upper left corner of the supply port 37a for supplying the game ball B to the firing standby position 36a to the arc of the outer peripheral surface of the inner rail 33, the detection unit of the actuating member 38 is usually used. 38a protrudes slightly downward beyond the tangent line M, and the blocking body 40 is held at the retracted position above the launch path of the game ball by engaging with the actuating member 38. In this state, when the game ball B supplied to the launch standby position 36a is hit by the hammer 23a, the game ball B enters the launch guide passage 34 through the launch path considerably below the detection unit 38a. Then, it passes through the ball return prevention piece 35 and enters the game area 8.

  In the pachinko machine P configured as described above, when the player rotates the operation handle 16, the game balls stored in the upper tray 13 are supplied one by one from the supply port 37a to the firing rail 36, and the firing standby position. Since the launching device 23 is operated in synchronism with it and the hammer 23a is swung in the firing direction with a strength corresponding to the operation amount of the operation handle 16, the game ball held at the launch standby position 36a is The hammers 23a are sequentially fired in the direction of the firing guide passage 34. At that time, the game ball B1 that has not been able to reach the game area 8 through the launch guide passage 34 due to insufficient momentum at the time of launching, as shown by the broken line in FIG. After falling into the space S, the foul ball is returned from the foul ball collection passage 41 through the ball collection unit 14a to the lower tray 14 as a foul ball. On the other hand, as shown by the solid line in FIG. 6, the game ball B with sufficient momentum at the time of launching jumps over the launch rail 36 and enters the launch guide passage 34, and then returns to the ball disposed at the upper end of the launch guide passage 34. It passes through the prevention piece 35 and enters the game area 8. As described above, when the game ball B that has entered the game area 8 in this way enters the start winning opening 25, 26, a special symbol display lottery result is performed, and a predetermined number of game balls are used as prize balls. It is paid out to the player. Further, when the game ball B flowing down in the game area 8 enters the general winning opening 27, only a predetermined number of gaming balls are paid out, and it does not enter any of the starting winning openings 25, 26 or the general winning opening 27. The game ball B is discharged from the out port 31 to the back side of the game board 7.

  Here, when the game ball B at the launch standby position 36a is hit by the hammer 23a, the game ball B is guided by the inclined surface of the launch rail 36 and passes considerably below the tangent line M, so that it is shown in FIG. As described above, the game ball B reaches the launch guide passage 34 without colliding with the detection portion 38a of the operation member 38, and the blocking body 40 is supported by the operation member 38 and held in the retracted position that is out of the passage path of the game ball. Has been. On the other hand, a person who intends to act illegally attaches and fixes the thread 42 to the game ball, supplies the threaded ball from the upper tray 13 to the firing standby position 36a and hits it with the hammer 23a of the launching device 23. In this case, as shown in FIG. 7, the game ball enters the game area 8 through the firing guide passage 34 with the thread 42 attached, but the thread 42 is connected to the firing standby position 36 a and the outer peripheral surface of the inner rail 33. After passing through a fixed route (tangent line M) defined between the two, the outer peripheral surface of the inner rail 33 passes through the upper end portion of the firing guide passage 34 and reaches the game area 8 together with the game ball. In other words, the game ball is supplied from the upper tray 13 through the supply port 37a to the launch standby position 36a of the launch rail 36, and is then launched toward the launch guide passage 34 by hitting the hammer 23a. The thread 42 attached to the game ball always reaches the game area 8 after passing through the tangent line M (a straight line extending from the upper left corner of the supply port 37a to the outer peripheral surface of the inner rail 33). As a result, the tension of the thread 42 lifts the detecting portion 38a of the operating member 38 to a position where it overlaps the tangent line M. Accordingly, the operating member 38 rotates in the direction of arrow α in FIG. In order to unlock the engagement receiving portion 40b, the blocking body 40 rotates in the direction of the arrow β by its own weight, and as shown in FIG. 5B, the blocking body 40 falls to the appearance position and the ball receiving portion 40c. Is in a posture that faces the launching path of the game ball.

  Therefore, the game ball B1 subsequently launched from the launching device 23 collides with the ball receiving portion 40c of the blocking body 40 on the near side of the launch guide passage 34 and changes its direction obliquely downward, as shown by the arrow in FIG. After that, the foul ball is returned from the foul ball collection passage 41 through the ball collection unit 14a to the lower tray 14 as a foul ball, and the game ball cannot reach the game area 8 after the ball with thread is launched. In other words, even if the ball with thread is awarded to the start winning opening 25, 26 to be in the jackpot game state, the game ball cannot be put into the attacker device 29 that operates during the jackpot game. It is no longer possible to illegally exploit prize balls using the attached ball. In addition, even if an intentional ball clogging (so-called grape state) is generated in the game area 8 to create a situation where it is easy to win a prize, the game ball cannot reach the game area 8 after the ball with thread is launched. Therefore, it is impossible to intentionally generate a ball clogging, and a ball clogging action using a ball with a thread can be suppressed.

  Further, when the ball with thread is led to the general winning opening 27 and the prize ball is illegally exploited, the ball with the first thread is not surely reached the target position of the game area 8 and is then fired. Since all the game balls cannot reach the game area 8, such illegal acts can be suppressed. In addition, since a fraudulent act using a threaded ball can be detected by the simple structural parts of the actuating member 38 and the blocking body 40, it is possible to prevent the detection structure from becoming complicated and costly. Further, when the blocking body 40 moves to the appearance position by using the threaded ball, the game ball subsequently launched from the launching device 23 collides with the ball receiving portion 40c of the blocking body 40 and is changed its direction, Since the foul balls are returned from the foul ball collection passage 41 through the ball collection portion 14a to the lower tray 14 as foul balls, it is possible to reliably prevent the game balls from being clogged.

  In the embodiment described above, the pachinko machine P provided with the start winning ports 25 and 26, the attacker device 29 and the like in the game area 8 of the game board 7 has been described. However, the present invention is specific to the game area 8 called a V zone. This is also applicable to the pachinko machine P provided with an area, and even in this case, even if the ball with thread is guided to the V zone to be in the jackpot game state, a prize ball is obtained during the jackpot game. Can not.

  In the above embodiment, the operating member 38 is rotated by the tension of the thread 42 attached to the game ball, and the blocking body 40 is moved from the retracted position to the appearance position accordingly. The movement of one of the member 38 and the blocking body 40 may be detected by a sensor, and a hall computer or the like may be informed that fraud has occurred based on the detection signal.
