Description

  The present invention relates to a ball game machine in which a game ball is launched into a game area of a game board when a player rotates a rotation operation body of a launch handle.

  This type of launching handle provided in a ball game machine includes a base body fixed below the front frame of the ball game machine and a rotating operation body supported rotatably at the front end of the base body. The turning operation body is urged to turn to an initial position by an elastic member such as a torsion spring. The turning operation body is a movable side member that is manually operated by the player, and the launch intensity of the game ball is adjusted according to the turning angle of the turning operation body. In this case, since maintaining a posture in which the player holds the rotating operation body with his / her palm for a long time is accompanied by considerable fatigue, a circular-shaped face cover connected and fixed to the base body in front of the rotating operation body A configuration is widely adopted in which the player operates the turning operation body with the fingertip while holding the face cover with the palm. In addition, a plurality of finger holders project from the outer peripheral surface of the rotating operation body at predetermined intervals in the circumferential direction, and some of these finger holders protrude forward and face the outer peripheral surface of the face cover. doing. Therefore, the player can press a plurality of fingertips (thumb, index finger, etc.) against each finger contact part with a wide contact area, and the restoring force per unit area acting on each finger from the elastic member is as much as possible. Therefore, the degree of fatigue experienced by each finger of the player can be greatly reduced.

  By the way, in the launching handle configured as described above, the protruding portion of the finger holding portion that is the movable side member extends around the rear end portion of the face cover that is the fixed side member, and the outer peripheral surfaces of these face covers Since a gap is formed between the protrusion and the protruding portion of the finger holder, a fraudulent act is easily performed in which a foreign object such as a medal or a coin is sandwiched from the front to fix the rotating operation body. Therefore, conventionally, by launching a ball game machine that prevents the action of fixing the rotating operation body with a foreign object such as a coin by providing a finger holder so as not to protrude forward from the outer peripheral surface of the rotating operation body. A handle has been proposed (see, for example, Patent Document 1). In this case, since the protruding portion that faces the outer peripheral surface of the rear end of the face cover from the finger holder is omitted, there is no gap for inserting foreign objects such as coins around the rear end of the face cover. It is impossible to fix the rotating operation body by inserting a foreign object therebetween.

Further, a rotary volume 12 is mounted on the substrate portion 8b, and a gear 13 is fixed to the rotary shaft of the rotary volume 12. The rotary volume 12 is a rotary operation type electric component that detects the amount of rotation of the rotary operation body 10, and the above-described control is performed by controlling the rotational driving force of the striking rod by a motor of a launcher (not shown) based on the detection signal. As described above, the launch intensity of the game ball is adjusted.

  A cylindrical bearing portion 9 a that protrudes rearward from the center and a plurality of leg portions 9 b that protrude rearward from the periphery of the bearing portion 9 a are formed on the inner peripheral surface of the face cover 9. A chamfered portion 9c that is tapered from the outer peripheral side toward the inner peripheral side is formed on the rear end surface over the entire periphery. The face cover 9 and the base body 8 are integrated with each other by inserting screws (not shown) from the back surface of the substrate portion 8b into the respective columns 8e and screwing them to the leg portions 9b. However, an annular space having a predetermined width is defined between the rear end face of the face cover 9 and the cylindrical jetty 8c of the base body 8, and the rotating operation body 10 is rotatably exposed from the annular space. ing.

  The rotating operation body 10 includes a ring portion 10a that protrudes outward from the annular space, a cylindrical portion 10b that protrudes forward from the front end surface of the ring portion 10a, and the like. The region is a base portion 10c. As shown in FIG. 7, the transmission body 14 is integrated with the rear end surface of the base portion 10 c using a fixing means such as a screw, and the transmission body 14 extends along the rotation center axis of the rotary operation body 10. And a shaft portion 14a protruding rearward. The distal end portion of the shaft portion 14 a is rotatably supported by the bearing tube portion 8 f of the base body 8, and the transmission body 14 functions as a rotating shaft that pivotally supports the rotating operation body 10 on the base body 8. A gear portion (not shown) is engraved on the outer peripheral surface of the shaft portion 14 a, and the gear portion meshes with the gear 13 described above, whereby the rotation operation body 10 is rotated via the transmission body 14 and the gear 13. Is transmitted to the rotary shaft of the rotary volume 12.

  Further, a rotation support shaft 10d is formed on the front end surface of the base portion 10c so as to protrude forward, and the rotation support shaft 10d and the shaft portion 14a of the transmission body 14 are arranged on the same line. The distal end portion of the rotation support shaft 10d is rotatably supported by the bearing portion 9a of the face cover 9, and the rotation operation body 10 is operated to rotate about the rotation support shaft 10d and the shaft portion 14a. A pair of arc-shaped holes 10e and spring receiving projections 10f are formed around the rotation support shaft 10d. The support protrusions 8d of the base body 8 and the respective pillars 8e are inserted through the arc-shaped holes 10e and the face cover 9 is inserted. Reached inside. As a result, the turning operation body 10 can be turned with respect to the base body 8 and the face cover 9 within a predetermined angle range. The turning range of the turning operation body 10 is the circumferential direction of the arc-shaped hole 10e. Are defined by the abutment of the two ends of the contact with the support 8e. As shown in FIG. 5, the rotating support shaft 10 d holds the winding portion 15 a of the torsion spring 15, and the pair of arms protruding from the winding portion 15 a rotate with the support protrusion 8 d of the base body 8. The operating body 10 is hooked on the spring receiving projection 10f. Thereby, the rotation operation body 10 is urged to rotate to the initial position in the rotation direction by the elastic force of the torsion spring 15 which is a return spring.

  The front end surface of the ring portion 10a is orthogonal to the rotation center axis of the rotary operation body 10, and a plurality of finger contact portions 10g protrude from the outer peripheral surface of the ring portion 10a at a predetermined interval in the circumferential direction. It is installed. These finger holders 10g have an extending part 10h that protrudes forward from the front end face of the ring part 10a, and the extending part 10h has an inclined surface 10i that faces the outer peripheral surface of the face cover 9 via a gap S1. Is formed. The inclined surface 10i is inclined in a direction in which the front end side is separated from the rear end side with respect to the rotation center axis of the rotating operation body 10, in other words, the inclined surface 10i is outside as the distance from the front end surface of the ring portion 10a increases. Has spread to. As a result, the gap S1 sandwiched between the extension 10h of the finger holder 10g and the outer peripheral surface of the face cover 9 is a space that is tapered from the near side toward the far side. Further, a gap S2 is secured between the front end face of the ring portion 10a and the rear end face of the face cover 9, and the turning operation body 10 can be smoothly turned with respect to the face cover 9 by this gap S2. It is like that. As described above, since the chamfered portion 9c is formed on the rear end surface of the face cover 9 over the entire circumference, the gap S2 sandwiched between the chamfered portion 9c and the front end surface of the ring portion 10a has a radial direction. It has a substantially V-shaped cross section that is tapered from the outside to the inside.

  The rotating operation body 10 is made of a surface of a synthetic resin material subjected to highly conductive plating, and is connected to a touch circuit (not shown). This touch circuit determines whether or not the turning operation body 10 is in contact with the player. When the touch operation body 10 is in contact, it is possible to supply power to the motor of the launching device described above.

  In the ball and ball game machine configured as described above, when the player holds the face cover 9 with his palm and presses the fingertip against the finger holder 10g to rotate the rotation operation body 10, the rotation operation body 10 is The rotary support shaft 10d and the shaft portion 14a rotate around the rotation support shaft 10d and the rotation is transmitted to the rotary shaft of the rotary volume 12 via the transmission body 14 and the gear 13. As a result, since the amount of rotation of the rotation operation body 10 is detected from the rotary volume 12, the game ball stored in the tray 5 is rotated by controlling the motor of the launching device based on this detection signal. It is fired toward the game area of the game board 3 with a firing intensity corresponding to the amount of rotation of the body 10. Further, the torsion spring 15 is stored with the turning operation of the turning operation body 10, and when the turning operation force with respect to the turning operation body 10 is removed, the turning operation body 10 becomes the torsion spring. It automatically returns to the initial position by the resilience of 15.

  Here, in the firing handle 7 according to the present embodiment example, the finger holding portion 10g protruding from the outer peripheral surface of the ring portion 10a of the rotating operation body 10 has an extending portion 10h facing the outer peripheral surface of the face cover 9. Therefore, it is possible to reduce the degree of fatigue by increasing the contact area between the finger holder 10g and the fingertip of the player. In addition, since the inclined surface 10i that is tapered with respect to the rotation center axis of the rotation operation body 10 is formed in the extending portion 10h of the finger holding portion 10g, as shown in FIG. Even if a foreign object 16 such as a medal or a coin is inserted from the front into the gap S1 that opens between the extended part 10h and the extended part 10h, the foreign object 16 is inserted into the outer peripheral surface of the face cover 9 and the inclined surface 10i of the extended part 10h. It cannot be sandwiched between. In other words, the sling is removed by inclining the opposing surface (inclined surface 10i) of the extending portion 10h that faces the outer peripheral surface of the face cover 9, so that the foreign matter 16 such as medals or coins is removed from the gap S1. Even if inserted from the front, the foreign matter 16 falls out of the gap S1, and the rotating operation body 10 cannot be fixed by the foreign matter 16 being sandwiched from the front.

  Further, since the chamfered portion 9c that is tapered from the outer peripheral side toward the inner peripheral side is formed on the rear end surface of the face cover 9 over the entire circumference, the rear end surface of the face cover 9 and the ring portion 10a are formed. Even if a foreign object 16 such as a medal or a coin is inserted from the side into a gap S2 generated between the front end surface of the face cover 9 and the front end surface of the ring cover 10a, the foreign object 16 cannot be sandwiched between the rear end surface of the face cover 9 and the front end surface of the ring portion 10a. It is like that. That is, even if a foreign object 16 such as a medal or a coin is inserted from the side with respect to the gap S2, the amount of insertion of the foreign object 16 is regulated by contacting the outer peripheral surface of the cylindrical portion 10b, and the face cover 9 Since the allowance for the foreign matter 16 is removed by the chamfered portion 9c, the foreign matter 16 falls out of the gap S2, and the rotating operation body 10 cannot be fixed by being caught from the side of the foreign matter 16. Since the turning operation body 10 cannot be fixed at the turning position by sandwiching the foreign object 16 in this way, the player must always turn the turning operation body 10 with his fingertip to play a game. It is possible to prevent an illegal act of playing in a state where the moving operation body 10 is fixed with the foreign object 16.

  FIG. 8 is a cross-sectional view of a launching handle according to another embodiment of the present invention, FIG. 9 is a detailed view of part A of FIG. 8, and parts corresponding to those of FIGS. Description is omitted.

  The firing handle 7 according to this embodiment is different from the above-described embodiment in that an inclined step portion 10j is formed on the front end surface of the ring portion 10a of the rotating operation body 10 over the entire circumference, and this inclination The stepped portion 10j is opposed to the chamfered portion 9c of the face cover 9, and the rest of the configuration is basically the same. The inclined stepped portion 10j is inclined in the opposite direction to the chamfered portion 9c of the face cover 9, and the clogged portion 9c and the inclined stepped portion 10j remove the foreign material from the face cover 9 and the ring portion 10a. ing. Therefore, when a foreign material 16 such as a medal or a coin is inserted from the side into the gap S2 between the rear end surface of the face cover 9 and the front end surface of the ring portion 10a, the foreign material 16 is chamfered as shown in FIG. Since the pinching is prevented by both the slopes of the portion 9c and the inclined step portion 10j, the foreign matter 16 drops off from the gap S2 and the rotating operation body 10 cannot be fixed.
