Description

  The present invention relates to a launch handle for a ball game machine that launches game balls into a game area of a game board.

  The launch handle of a ball game machine represented by a pachinko machine usually has a base body that is fixed to the bottom of the front frame of the ball game machine and protrudes forward, and a circular bowl shape that is fixed to the front end of this base body. And a rotating operation body disposed rotatably between the base body and the face cover. The rotating operation body is rotated to an initial position by a return spring including a torsion spring. It is energized. The rotating operation body is a movable side member that is manually operated by the player. The rotation amount of the rotating operation body is detected by a detection element such as a rotary volume, and the motor of the launching device strikes based on the output signal. By controlling the rotational driving force of the kite, the game ball is launched with a firing strength corresponding to the rotational angle of the rotational operation body. The rotating operation body is made of a surface of a synthetic resin material subjected to a highly conductive plating process, and the plated portion on the surface is electrically connected to the touch circuit. This touch circuit determines whether or not the player is in contact with the rotating operation body, and power is supplied to the motor of the launcher only when the player is in contact with the rotating operation body. It has become.

  In a ball game machine equipped with such a launching handle, the ring portion of the rotating operation body, which is a movable side member, extends behind the face cover, which is a fixed side member. Since there is a gap between the surroundings and the inner peripheral surface of the ring part, if a rotating operation body is fixed by inserting a foreign object such as a medal or a coin into the gap, the player can move his hand from the rotating operation body. Even if the touch circuit is turned off, the rotating operation body can be maintained at the optimum firing angle without readjustment of the firing strength. Therefore, this has been a factor for allowing an illegal act of playing a game simply by touching a player's hand with a rotating operation body fixed with a foreign object.

Therefore, conventionally, a launch handle of a ball game machine in which a circular hook-shaped portion corresponding to the face cover is integrally formed with the rotating operation body and the rotating operation body can be moved in the front-rear direction with respect to the base body. Has been proposed (see, for example, Patent Document 1). In this case, there is no fixed side member in front of the rotating operation body which is a movable side member, and foreign players cannot be sandwiched between these members to fix the rotating operation body. The turning operation body must be held at an arbitrary angle by hand, and an illegal act of playing a game simply by touching the turning operation body fixed with a foreign object by the player's hand can be prevented.
JP 2002-210096 A

  As described above, the conventional launching handle disclosed in Patent Document 1 can prevent an illegal act of playing a game with a rotating operation body fixed by a foreign object, but a fixed-side member that can support a player's palm is not capable of rotating. Since the player does not exist in front of the moving operation body, it is necessary for the player to maintain a posture in which the rotating operation body rotated at an arbitrary angle is held with a palm. There was a problem that.

  The present invention has been made in view of such a state of the art, and its purpose is to reduce fatigue caused by long-time games and to fix a rotating operation body by inserting foreign objects such as medals and coins. An object of the present invention is to provide a launch handle for a ball game machine that can prevent an illegal act of playing a game while it is being played.

  In order to achieve the above-mentioned object, the present invention provides a base body having a cylindrical jetty on the outer peripheral portion, and a conical shape that is fixed to the base body and defines an annular space between the cylindrical jetty. A face cover, a turning operation body that can turn in the annular space, a return spring that urges the turning operation body to an initial position in the turning direction, and rotation of the turning operation body is detected. A launching handle of a ball game machine in which a launching intensity of a game ball is adjusted based on an output signal of the detection element, and a main body in which the turning operation body turns inside the annular space And a ring part that rotates outward from the annular space, and supports a detection body arranged on the inner side of the ring part so as to be swingable about the rotation center axis of the rotation operation body. And a switch for detecting the swinging motion of the detection body and stopping the launch of the game ball The stage is provided, and configured to expose the sensing member into the gap that exists between the inner circumferential surface of the ring portion and the rear portion outer peripheral surface of the face cover.

  In the launch handle of the ball game machine configured as described above, a face cover that is a fixed side member exists in front of a rotating operation body that is a movable side member, and the player supports the palm on the face cover. Since the ring portion of the rotating operation body can be rotated in a state where the game is in a state of being played, fatigue associated with a long-time game can be reduced. Further, when a foreign object such as a medal or a coin is inserted into the gap between the rear outer peripheral surface of the face cover and the inner peripheral surface of the ring portion, the detecting body swings around the fulcrum by the insertion force of the foreign object, and the detecting body Since the switch means detects the swinging motion and stops the launch of the game ball, it is possible to prevent an illegal act of playing the game with the foreign object sandwiched and the rotating operation body fixed.

  In the above configuration, a device such as a push switch or a lever switch may be used as the switch means, and a plurality of such devices may be arranged on the back side of the detection body at a predetermined interval in the circumferential direction. Is constituted by a movable contact portion provided on the detection body and a fixed contact portion arranged opposite to the movable contact portion with a predetermined gap, and the swinging operation of the detection body is performed using a simple configuration switch means. This is preferable because it can be detected.

  Further, in the above configuration, when a support protrusion serving as a swing fulcrum of the detection body is provided at the rotation center of the rotating operation body, and a spring member that urges the detection body toward the support protrusion is held on the face cover, It is preferable that the detection body can be stably swung by insertion of a foreign substance.

Since the ring part of the rotating operation body can be rotated, it is possible to reduce fatigue caused by long-time games, and in the gap between the rear outer peripheral surface of the face cover and the inner peripheral surface of the ring part. When a foreign object such as a medal or a coin is inserted, the detecting body swings around the fulcrum by the insertion force of the foreign object, and the swinging operation of the detecting body is detected by the switch means to stop the game ball from firing. In addition, it is possible to prevent an illegal act of playing a game while holding the rotating operation body with a foreign object interposed therebetween.

  The base body 8 includes a cylindrical portion 8a that protrudes forward from the front board 6 and a circular base portion 8b that protrudes radially outward from the front end portion of the cylindrical portion 8a. A cylindrical jetty 8c protruding forward is formed at the periphery, and a bearing cylinder 8d is formed at the center of the base body 8b. A firing stop switch 13 is mounted on the front side of the base body portion 8b, and this firing stop switch 13 is operated by a pressing operation of a lever portion 13a protruding outward from the base body 8. A rotary volume 14 is mounted on the back side of the base portion 8b, and a rotary shaft 14a of the rotary volume 14 projects forward through the base portion 8b. The rotary volume 14 is a detection element that detects the amount of rotation of the rotary operation body 10, and the motor of the launcher (not shown) controls the rotational driving force of the striking rod based on the detection signal, as described above. The launch intensity of the game ball is adjusted according to the turning angle of the turning operation body 10.

  The face cover 9 is a fixed side member arranged on the most front side of the firing handle, and the face cover 9 is integrated with a plurality of pillars 8e protruding from the base portion 8b of the base body 8 using screws (not shown). Has been. However, an annular space K having a predetermined width is defined between the rear end surface of the face cover 9 and the front end surface of the cylindrical jetty 8c, and the rotating operation body 10 can be rotated in the annular space K. Has been placed. In addition, a plurality of spring receiving projections 9 a are formed on the inner peripheral surface of the face cover 9, and these spring receiving projections 9 a are arranged in front of the detection body 11 at equal intervals in the circumferential direction.

  The rotating operation body 10 is formed with a main body portion 10a that rotates inward from the annular space K and a ring portion 10b that rotates outward from the annular space K. A plurality of finger holders 10c are projected from the outer peripheral surface of 10b at predetermined intervals in the circumferential direction. A transmission body 15 is fixed to the rear end surface of the main body 10a by screwing or the like, and this transmission body 15 has a shaft portion 15a that protrudes rearward along the rotation center axis P of the rotary operation body 10. Yes. The shaft portion 15 a is rotatably supported by the bearing tube portion 8 d, and the transmission body 15 functions as a rotation shaft that pivotally supports the rotating operation body 10 on the base body 8. Further, a torsion spring 16 that is a return spring is wound around the distal end portion of the shaft portion 15 a, and the rotating operation body 10 is biased to the initial position in the rotating direction by the elastic force of the torsion spring 16. . Further, a gear portion (not shown) is engraved on the outer peripheral surface of the transmission body 15, and a gear 17 attached to the rotary shaft 14 a of the rotary volume 14 is engaged with the gear portion. As a result, the rotation of the rotary operation body 10 is transmitted from the transmission body 15 to the rotary shaft of the rotary volume 14 via the gear 17.

  The rotating operation body 10 is made of a surface of a synthetic resin material subjected to highly conductive plating, and a capacitor 18 that is in contact with the plated surface is attached to the rear end surface of the main body portion 10a. The capacitor 18 is connected to a touch circuit (not shown). When the player touches the surface of the rotary operation body 10 and the capacitance of the capacitor 18 changes, the touch circuit changes based on the capacitance change of the capacitor 18 as described above. Power is supplied to the motor of the launcher. A pair of escape holes 10e are formed in the main body 10a, and each support 8e of the base body 8 reaches the inside of the face cover 9 through the escape holes 10e. A contact base 12 is fixed to the front end surface of the main body portion 10a via a separator 19, and a hemispherical support protrusion 10d is formed at the center of the front end surface of the main body portion 10a. The separator 19 is made of an insulating material such as synthetic resin, and a cylindrical portion 19a surrounding the support protrusion 10d is formed at the center thereof. The contact base 12 is made of a conductive material obtained by plating the surface of a metal plate or synthetic resin, and the contact base 12 is insulated from the plated surface of the rotating operation body 10 by a separator 19. A somewhat thick contact portion 12 a is formed on the outer peripheral edge of the contact base 12, and a predetermined gap is secured between the contact portion 12 a and the back side of the detection body 11. The contact base 12 and the separator 19 are formed with relief holes 12b and 19b for inserting the respective columns 8e of the base body 8 (see FIG. 6).

  The inner peripheral surface of the ring portion 10b of the rotating operation body 10 faces the outer peripheral surface of the cylindrical jetty 8c and the rear outer peripheral surface of the face cover 9, and when viewed from the front of the firing handle 7, the face cover An annular gap S is formed between 9 and the ring portion 10b (see FIG. 3). On the other hand, the rear end portion of the ring portion 10b is disposed so as to cover the outer peripheral portion of the base portion 8b, and it is difficult to insert a foreign object between the ring portion 10b and the tubular jetty 8c from the rear of the firing handle 7. It is

  The detection body 11 is formed with a disk-shaped substrate portion 11a facing the contact base 12, and an operation portion 11b protruding forward from the outer peripheral edge of the substrate portion 11a. The operation portion 11b is an inner portion of the ring portion 10b. It is exposed in the gap S described above facing the peripheral surface. A plurality of protrusions 11c and a plurality of circular holes 11d are formed in the substrate portion 11a, and the pillars 8e of the base body 8 are inserted through the circular holes 11d. A coil spring 20 is interposed as an example of a spring member between each projection 11c of the substrate portion 11a and each spring receiving projection 9a of the face cover 9, and the substrate portion 11a is uniformly elasticized from each coil spring 20. The force is pressed against the support protrusion 10d of the rotary operation body 10 under force. As a result, the detection body 11 can swing in all directions of 360 degrees around the support protrusion 10d, and the detection switch 21 which is a switch means for stopping firing is detected by the detection body 11 and the contact base 12 described above. Is configured. Normally, the detection switch 21 is maintained in the off state by the detection body 11 being separated from the contact base 12, but as will be described later, the detection body 11 is swung by the insertion of a foreign object to contact the contact base 12. Then, the detection switch 21 is switched from the off state to the on state. It should be noted that when both the firing stop switch 13 and the detection switch 21 described above are turned on, a firing stop signal is output, and the power supply to the motor of the launching device is cut off based on these firing stop signals, thereby rotating The launch of the game ball is stopped regardless of the turning operation of the operating body 10.

  In the ball and ball game machine configured as described above, in a non-game state in which the turning operation body 10 is not turned, the turning operation body 10 is moved to the initial position in the turning direction by the resilient force of the torsion spring 16. Is retained. Further, as shown in FIGS. 4 and 5, since the detection body 11 receives a uniform elastic force from each coil spring 20 and is pressed against the support protrusion 10d, the contact between the back surface of the substrate portion 11a and the contact base 12 is achieved. A predetermined gap is secured between the contact portion 12a and the detection switch 21 is kept off. Then, when the player holds the face cover 9 with his / her palm and presses the fingertip against the finger holder 10c to rotate the ring portion 10b in the clockwise direction of FIG. 3, a touch circuit (not shown) detects the player's contact. Then, while supplying electric power to the motor of the launching device, the rotating operation body 10 rotates about the shaft portion 15a of the transmission body 15, the rotation of the rotary volume 14 rotates from the transmission body 15 via the gear 17. Transmitted to the shaft. As a result, a detection signal corresponding to the amount of rotation of the rotary operation body 10 is output from the rotary volume 14, and the motor of the launching device is controlled based on this detection signal, so that the game ball stored in the tray 5 is rotated. The game is fired toward the game area of the game board 3 with a launch intensity corresponding to the amount of rotation of the moving operation body 10. Further, the torsion spring 16 is stored with the turning operation of the turning operation body 10, and when the turning operation force on the turning operation body 10 is removed, the turning operation body 10 is moved to the torsion spring. It automatically returns to the initial position by the resilience of 16.

  If, for example, the number of holding balls becomes four during the game, and the player presses the lever portion 13a with a thumb or the like, a firing stop signal is output from the firing stop switch 13 to the launching device, and the player rotates. Irrespective of the turning operation of the operating body 10, the launch of the game ball is temporarily stopped.

  Here, in the launch handle 7 according to the present embodiment example, a face cover 9 that is a fixed side member exists in front of the rotary operation body 10 that is a movable side member, and the player holds the palm during the game. Since the ring portion 10b of the rotating operation body 10 can be rotated while being supported by the face cover 9, it is possible to significantly reduce the player's hand fatigue associated with a long game. Further, the detection body 11 functioning as a movable contact portion of the detection switch 21 is swingably supported on the support protrusion 10d of the rotation operation body 10, and the operation portion 11b of the detection body 11 is connected to the rear outer peripheral surface of the face cover 9. Since it is exposed in an annular gap S existing between the front inner peripheral surface of the ring portion 10b, a foreign object 22 such as a medal or a coin is inserted into an arbitrary portion of the gap S as shown in FIG. When the rotation operation body 10 is fixed at the optimum firing angle, the detection body 11 swings around the support protrusion 10d by the insertion of the foreign object 22, and the substrate portion 11a contacts the contact portion 12a of the contact base 12. Thus, the detection switch 21 is switched from the off state to the on state. As a result, since a detection stop signal is output to the launching device from the detection switch 21 that has been turned on, the launch of the game ball is stopped despite the fact that the turning operation body 10 is turning at an arbitrary angle. Therefore, it becomes impossible to fire the game ball while the foreign object 22 is sandwiched and the rotating operation body 10 is fixed. Therefore, the player must perform a game by rotating the ring portion 10b of the rotating operation body 10 with a fingertip, and prevents an illegal act of playing with the rotating operation body 10 fixed by the foreign object 22. be able to.

  Further, in the launching handle 7 according to the present embodiment example, the detection body 11 that is swingably supported by the support protrusion 10d of the rotating operation body 10 and the contact base that is fixed to the main body 10a of the rotating operation body 10 are provided. 12 are arranged opposite to each other through a predetermined gap, and the detection switch 21 serving as a switch means for stopping the emission is configured by the detection body (movable contact portion) 11 and the contact base (fixed contact portion) 12. The swinging motion of the detector 11 can be detected using the switch means. However, a device such as a push switch or a lever switch may be used as the switch means, and a plurality of such devices may be arranged on the back side of the detection body 11 at a predetermined interval in the circumferential direction.

  Further, in the launch handle 7 according to the present embodiment example, a support protrusion 10 d serving as a swing fulcrum of the detection body 11 is provided at the rotation center of the rotation operation body 10, and the detection body is provided on each spring receiving protrusion 9 a of the face cover 9. Since the coil spring 20 that elastically biases 11 toward the support protrusion 10d is held, the detection body 11 can be stably swung by inserting the foreign material 22. However, it is also possible to provide a support projection as a swing fulcrum of the detection body 11 on the base body 8 instead of the rotation operation body 10.

  In the above-described embodiment, when the detection switch 21 which is the switch means for stopping the firing is turned on and the firing stop signal is output, the launch of the game ball is surely stopped based on the firing stop signal. However, as shown in the flowchart of FIG. 8, even if the detection switch 21 is turned on, it is recognized as illegal only when a predetermined time has elapsed (for example, after 5 to 8 seconds), and the game ball is fired. May be stopped. In this case, for example, even if the detection body 11 comes into contact with the rotation operation body 10 during the rotation operation and the detection switch 21 is temporarily turned on, the elapsed time of the on state is judged to be illegal. Since it is determined whether or not it is an action, it is possible to prevent erroneous detection other than insertion of the foreign object 22.

  In the above embodiment, the detecting body (movable contact portion) 11 and the contact base (fixed contact portion) 12 are configured as switch means for detecting the swinging motion of the detecting body 11 and stopping the launch of the game ball. In the above description, the contact detection switch 21 is used. However, an optical detection switch in which the light receiving and emitting elements are allocated to the detection body 11 and the contact base 12, and a magnet and a magnetic detection are used for the detection body 11 and the contact base 12. It is also possible to use a magnetic detection switch to which the elements are distributed.

  In the above embodiment, the case where the rotary volume 14 is used as a detection element for detecting the rotation of the rotary operation body 10 has been described. However, other devices such as a rotary encoder can also be used as the detection element. is there.
