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.

  This type of launching handle includes a base body that is fixed below the front frame of the ball game machine and protrudes forward, and a rotating operation body that is rotatably supported at the front end of the base body. The rotating operation body is urged to rotate to the initial position by a return spring 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 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. Further, a plurality of finger holders project from the outer peripheral surface of the rotating operation body, and these finger holders have a protruding portion that protrudes forward and faces the outer peripheral surface of the face cover. Therefore, the player can press a plurality of fingertips (thumb, forefinger, etc.) against each finger contact part with a wide contact area, and the return force per unit area acting on each finger from the return spring 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 there is a gap between the projection and the protruding part of the finger holder, a foreign object such as a medal or coin is inserted into the gap from the front, and the rotation operation body is fixed at an arbitrary rotation angle. It is easy to carry out fraudulent acts of continuous firing. Therefore, conventionally, by providing the finger holder so as not to protrude forward from the outer peripheral surface of the rotating operation body, the act of fixing the rotating operation body to an arbitrary rotation angle using a foreign object such as a coin is prevented. There has been proposed a launch handle for a ball game machine as described above (see, for example, Patent Document 1). In this case, the protruding portion that overlaps with the outer peripheral surface of the rear end of the face cover is omitted from the finger rest, so there is no gap around the rear end of the face cover for inserting foreign objects such as coins. A rotating operation body cannot be fixed at an arbitrary rotation angle by inserting a foreign object into the gap.
JP 2001-170267 A

  As described above, in the conventional launching handle disclosed in Patent Document 1, foreign matter such as coins cannot be sandwiched from the front between the outer peripheral surface of the rear end of the face cover and the finger contact part of the rotating operation body. However, since there are other gaps that allow foreign objects to be sandwiched, it is difficult to completely prevent the act of fixing the rotating operation body using the foreign objects. That is, the base body and the face cover are integrated with each other to form a fixed side member, and a rotating operation body that is a movable side member is rotatably disposed between the base body and the face cover. Because of this, a clearance (clearance) is required between the rotating operation body and the base body or face cover to ensure smooth rotation of the rotating operation body. However, a gap is secured between the rear end surface of the face cover and the front end surface of the rotating operation body. Therefore, if a foreign object such as a coin is inserted into the gap in a substantially vertical posture from the side, the foreign object can be sandwiched between the rear end surface of the face cover and the front end surface of the rotating operation body. It is possible to launch a game ball with the moving operation body fixed at an arbitrary rotation angle.

  The present invention has been made in view of the situation of the prior art as described above, and an object thereof is a ball game machine capable of preventing an action of playing with a rotating operation body fixed with a foreign object such as a medal or a coin interposed therebetween. It is to provide a firing handle.

  In order to achieve the above object, the present invention provides a base body fixed to a gaming machine and protruding forward, a face cover fixed to the front end portion of the base body, and between the base body and the face cover. And a rotary electric component that detects the rotation of the rotary operation body, and emits a game ball according to the rotation angle of the rotary operation body. In the launch handle of the ball game machine whose strength is adjusted, the rotating operation body is an endless type whose angle is not restricted in the rotation direction, and is moved in the front-rear direction by being splined inside the rotation operation body. A possible clutch ring, an elastic member that urges the clutch ring forward, and a return spring that urges the rotary electrical component to an initial position in the rotational direction. By force When held at the forward position, the rotation of the rotating operation body is transmitted to the rotating electrical component via the clutch ring, and between the face cover and the rotating operation body. When the clutch ring moves to the retracted position due to the inserted foreign matter, the power transmission path from the clutch ring to the rotating electrical component is blocked.

  In the launch handle of the ball game machine configured as described above, when the player rotates the rotating operation body, the clutch ring splined inside the rotating operation body rotates integrally, and the rotation Is transmitted to a rotary electric component such as a rotary volume via a power transmission path, and a detection signal corresponding to the rotation angle of the rotary operation body is output from the rotary electric component, and a game is played based on the detection signal. The firing strength of the sphere is adjusted. In this state, if a foreign object such as a medal or a coin is inserted and inserted between the face cover and the rotating operation body, the clutch ring moves to the retracted position by the insertion force of the foreign object, so that the rotating electrical component from the clutch ring Since the power transmission path leading to is cut off, the rotary electrical component automatically returns to the initial position by the elastic force of the return spring. Therefore, the rotating operation body can be fixed with the foreign object sandwiched therebetween, but the rotating electrical component is automatically returned to the initial position, so that the game ball cannot be launched with the foreign object sandwiched therebetween. Further, when a foreign object sandwiched between the face cover and the rotating operation body is removed, the clutch ring moves to the forward position by the elastic force of the elastic member, so that the power transmission path from the clutch ring to the rotating electrical component However, since the rotating operation body is an endless type whose angle is not restricted in the rotation direction, if the rotating operation body is rotated again from the position where the power transmission path is in the continuous state, the rotation operation body rotates. The mold electrical component is moved from the initial position to detect the rotation of the rotating operation body.

  In the above configuration, as an example for realizing the power transmission path, the first gear portion is provided at the rotation center of the clutch ring, and the second gear portion is provided on the rotation shaft of the rotary electrical component. A configuration in which the first and second gear portions are selectively engaged and disengaged as the clutch ring moves in the front-rear direction can be employed. Alternatively, as an example for realizing the power transmission path, a rotary plate connected to the rotary shaft of the rotary electrical component is disposed inside the face cover, and the clutch is moved along with the movement of the clutch ring in the front-rear direction. A configuration in which the ring and the rotating plate are selectively engaged and disengaged can be employed.

  In the above configuration, the rotating operation body is an endless type that does not have a reference position in the rotation direction. If the projection is formed, the power transmission path repeats continuation / interruption, and even if the initial position of the rotating electrical component and the relative angle of the rotating operating body change, Since the finger holding portion always protrudes with the same interval, the player can easily rotate the rotating operation body by pressing the finger against an arbitrary finger holding portion.

  The launch handle of the ball ball game machine according to the present invention is configured such that when the player rotates the rotating operation body with a finger, the clutch ring that rotates integrally with the rotating operation body rotates through the power transmission path. By being transmitted to the rotating electrical component, the game ball is launched with a firing strength corresponding to the rotation angle of the rotating operation body, but the coin with the clutch ring inserted between the face cover and the rotating operation body Since the power transmission path from the clutch ring to the rotating electrical parts is cut off when moving to the retracted position by a foreign object such as a foreign object, the launch of the game ball will be stopped when the foreign object is caught In addition, it is possible to prevent an illegal act of playing a game with a rotating operation body fixed with a foreign object interposed therebetween.

  An embodiment of the invention will be described with reference to the drawings. FIG. 1 is a perspective view of a ball game machine equipped with a firing handle according to a first embodiment of the present invention, and FIG. 2 is a side view of the firing handle. 3 is a front view of the firing handle, FIG. 4 is a perspective view of the rotating operation body and the clutch ring provided in the firing handle as seen from the back side, and FIG. 5 is a cross-sectional view showing the internal structure of the firing handle. 6 is a perspective sectional view of the firing handle, and FIG. 7 is a perspective sectional view showing a state in which a foreign object is inserted into the firing handle.

  As shown in FIG. 1, a ball game machine according to the present embodiment includes a machine frame 1 installed in an island facility of a game arcade, and a front frame 2 attached to the machine frame 1 so as to be openable and closable in a door shape. A front board having a game board 3 housed in the front frame 2, a glass frame 4 attached to the front surface of the front frame 2 so as to be openable and closable, and a tray 5 disposed on the lower side of the front frame 2 6 and a launching handle 7 attached to the front board 6, and the like so that game balls stored in the tray 5 are launched toward the game area of the game board 3 using the launching handle 7. It has become.

  As shown in FIGS. 2 to 6, the firing handle 7 includes a base body 8 attached to the front board 6 and protruding forward, and a circular face cover 9 fixed to the front end of the base body 8. The rotary operation body 10 is rotatably supported between the base body 8 and the face cover 9, the clutch ring 11 is splined to the inside of the rotation operation body 10, and the base body 8 includes It is mainly configured by the attached rotary volume 12, and the launch intensity of the game ball is adjusted according to the rotation angle of the rotation operation body 10 operated by the player's fingertip.

  The base body 8 has a cylindrical main body portion 8a that protrudes forward from the front board 6 and a circular substrate portion 8b that closes the front end surface of the main body portion 8a, and the peripheral portion of the substrate portion 8b is the periphery of the main body portion 8a. Projecting radially outward from the outer peripheral surface. An annular groove 8c is formed in the front peripheral edge portion of the substrate portion 8b, and a bearing tube portion 8d is formed in the center of the substrate portion 8b. A rotary volume 12 is mounted on the back surface of the substrate portion 8b, and the rotary shaft of the rotary volume 12 penetrates the substrate portion 8b and projects forward. The rotary volume 12 is a rotary electric component that detects the amount of rotation of the rotary operation body 10, and the launching device motor (not shown) controls the rotational driving force of the striking rod based on the detection signal. Thus, the launch intensity of the game ball is adjusted.

  The face cover 9 is a fixed side member disposed on the most front side of the firing handle 7, and a guide tube portion 9 a is formed to protrude from the center of the inner surface of the face cover 9. The face cover 9 and the base body 8 are integrated by using fixing means such as screws, and the rotational operation body 10 disposed between the base body 8 and the face cover 9 is angle-regulated in the rotational direction. It is not endless type. The rotating operation body 10 is formed with a ring portion 10b having a finger holding portion 10a on the outer peripheral surface, and a plurality of (for example, eight) finger holding portions 10a are formed at equal intervals in the circumferential direction of the ring portion 10b. Has been. The front end surface of the ring portion 10b projects slightly forward from the rear end surface of the face cover 9, and a gap S is secured between the front end inner peripheral surface of the ring portion 10b and the rear end outer peripheral surface of the face cover 9. Yes. Further, a plurality of guide grooves 10c having a V-shaped cross section are formed at equal intervals in the circumferential direction on the inner peripheral surface of the ring portion 10b, and these guide grooves 10c are formed on the rotation center axis of the rotation operation body 10. Along the longitudinal direction.

  The clutch ring 11 has an annular small-diameter portion 11a disposed inside the face cover 9, and an annular large-diameter portion 11b continuous with the rear end of the annular small-diameter portion 11a. The front end of the annular large-diameter portion 11b The surface is exposed in the gap S described above. A plurality of protrusions 11c having a V-shaped cross section are formed at equal intervals in the circumferential direction on the outer peripheral surface of the rear end of the annular large diameter portion 11b, and these protrusions 11c are engaged with the guide grooves 10c of the rotating operation body 10. By doing so, the clutch ring 11 is spline-coupled to the rotary operation body 10 and can move forward and backward. Further, an elastic member 13 made of a coil spring, a leaf spring, or the like is interposed between the rear end surface of the annular large diameter portion 11b and the annular concave groove 8c of the base body 8, and the elastic force of the elastic member 13 is provided. Thus, the clutch ring 11 is biased forward.

  A front shaft portion 11 d and a rear shaft portion 11 e are formed on the annular small diameter portion 11 a of the clutch ring 11, and these shaft portions 11 d and 11 e protrude in the front-rear direction along the rotation center axis of the rotary operation body 10. Yes. The front shaft portion 11d is rotatably supported by the guide tube portion 9a of the face cover 9 and can be moved forward and backward. The rear shaft portion 11e is supported by the bearing tube portion 8d of the base body 8 and can be rotated and moved forward and backward. . A gear 11f is engraved on the outer peripheral surface of the rear shaft portion 11e, and a gear 14 is disposed in the vicinity of the gear 11f. The gear 14 is fixed to the rotary shaft of the rotary volume 12 described above, and both rotate integrally. Further, a torsion spring 15 as a return spring is wound around the rotating shaft of the rotary volume 12, and the rotary volume 12 is biased to an initial position by receiving the elastic force of the torsion spring 15. Instead of using such a torsion spring 15, a rotary volume with a self-return function incorporating a return spring may be used.

  The gear 11f and the gear 14 can be engaged and disengaged as the clutch ring 11 moves back and forth, and the clutch ring 11 is held in the forward position by the elastic force of the elastic member 13 as shown in FIGS. In this case, the gear 11f is also in the forward position and meshes with the gear 14. Only when the gear 11f and the gear 14 are in mesh with each other, the rotation of the rotating operation body 10 is transmitted from the clutch ring 11 to the rotary volume 12 via the mesh of the gear 11f and the gear 14. On the other hand, as shown in FIG. 7, when the clutch ring 11 moves to the retracted position by inserting the foreign matter 16 such as a medal or a coin into the gap S described above, the gear 11 f moves rearward and disengages from the gear 14. The power transmission path from the clutch ring 11 to the rotary volume 12 is interrupted.

  In the ball game machine configured as described above, the clutch ring 11 is held in the forward position by the elastic force of the elastic member 13 in a non-operating state in which the player does not touch the firing handle 7, and the gear 11 f and the gear 14 are in mesh with each other, and the rotary volume 12 is returned to the initial position by the elastic force of the torsion spring 15. In this state, when the player holds the face cover 9 with his / her palm and presses the fingertip against the finger holder 10a to rotate the rotation operation body 10, the clutch is spline-coupled inside the rotation operation body 10. The ring 11 rotates integrally around the shaft portions 11d and 11e, and the rotation is transmitted to the rotary volume 12 through meshing of the gear 11f and the gear 14 which are power transmission paths. As a result, a detection signal corresponding to the amount of rotation operation of the rotation operation body 10 is output from the rotary volume 12, and the motor is stored in the tray 5 by controlling the motor of the launching device based on this detection signal. The game ball is fired toward the game area of the game board 3 with a launch intensity corresponding to the turning amount of the turning operation body 10. Further, since the torsion spring 15 is stored with the turning operation of the turning operation body 10, when the turning operation force on the turning operation body 10 is removed, the turning operation body 10 and the clutch ring are removed. 11 and the rotary volume 12 are automatically returned to the positions before the operation by the elastic force of the torsion spring 15.

  Further, a foreign material 16 such as a medal or a coin is inserted into the gap S in a state where the rotational operation body 10 is rotationally operated, and the foreign material 16 is inserted into the outer peripheral surface of the rear end of the face cover 9 and the ring portion 10 b of the rotational operation body 10. 7 and the rotating operation body 10 is fixed, the clutch ring 11 is moved to the retracted position by the insertion force of the foreign matter 16 as shown in FIG. 7, so that the meshing state of the gear 11f and the gear 14 is released. Thus, the power transmission path from the clutch ring 11 to the rotary volume 12 is interrupted. As a result, the rotary volume 12 is automatically returned to the initial position by the resilience of the torsion spring 15, so that the output of the rotary volume 12 becomes zero and the launch of the game ball stops. Since the rotary volume 12 automatically returns to the initial position when the foreign object 16 is sandwiched in the gap S in this way, the player must manually operate the rotary operation body 10 to maintain the optimal firing angle. In other words, it is possible to prevent an illegal act of playing with the foreign object 16 being sandwiched and the rotational operation body 10 being fixed.

  When the foreign matter 16 sandwiched in the gap S is extracted, the clutch ring 11 moves to the forward position by the elastic force of the elastic member 13, so that the gear 11 f meshes with the gear 14 and reaches the rotary volume 12 from the clutch ring 11. The power transmission path is again in the continuous state. At this time, since the turning operation body 10 is an endless type whose angle is not restricted in the rotation direction, when the turning operation body 10 is turned again from the position where the power transmission path is in the continuous state, the rotary volume 12 is moved. The amount of rotation of the rotating operation body 10 can be detected by rotating from the initial position. Further, in the endless type rotating operation body 10 having no reference position in the rotation direction as described above, a plurality of finger contact portions 10a having the same shape protrude from the outer peripheral surface of the ring portion 10b at equal intervals in the circumferential direction. Therefore, even if the initial position of the rotary volume 12 and the relative angle of the rotary operation body 10 change due to repeated / continuation of the power transmission path (engagement / disengagement of the gear 11f and the gear 14), Each finger holder 10a always protrudes at the same position from the rotating operation body 10 when not operated. Therefore, the player can always press the finger in the same posture with respect to the finger holding portion 10a of the rotating operation body 10 in the non-operating state, and can easily rotate the rotating operation body 10. Can do.

  FIG. 8 is a cross-sectional view showing the internal structure of the launching handle according to the second embodiment of the present invention, and FIG. 9 is a cross-sectional view showing a state in which a foreign object is inserted into the launching handle, corresponding to FIGS. The duplicated explanation is omitted by attaching the same reference numerals to the portions.

  The second embodiment differs from the first embodiment described above in that a rotary plate 17 connected to the rotary shaft of the rotary volume 12 is disposed inside the face cover 9 and the clutch ring 11 moves forward and backward. The clutch ring 11 and the rotating plate 17 are selectively engaged and disengaged with the movement, and the other configurations are basically the same.

  The rotary plate 17 is formed with a front shaft portion 17 a and a rear shaft portion 17 b, and these shaft portions 17 a and 17 b protrude in the front-rear direction along the rotation center axis of the rotary operation body 10. The front shaft portion 17a is rotatably supported by the guide tube portion 9a of the face cover 9, and the rear shaft portion 17b is rotatably supported by the bearing tube portion 8d of the base body 8. Further, the tip of the rear shaft portion 17b is connected to the rotary shaft of the rotary volume 12, and the rotation of the rotary plate 17 is directly transmitted to the rotary shaft of the rotary volume 12. A torsion spring 18 as a return spring is wound around the front shaft portion 17a, and the rotary plate 17 and the rotary volume 12 are biased to an initial position by receiving the elastic force of the torsion spring 18.

  The clutch ring 11 that is splined to the inside of the rotating operation body 10 is urged forward by the elastic force of the elastic member 13 as in the first embodiment, and receives the elastic force of the elastic member 13. The clutch ring 11 is in pressure contact with a flange portion 17 c formed on the outer peripheral edge of the rotating plate 17. That is, when the clutch ring 11 is held at the forward movement position as shown in FIG. 8, the clutch ring 11 and the rotary plate 17 are friction-coupled by the elastic force of the elastic member 13, and in this case, the clutch ring 11 rotates. The rotation of the operating body 10 is transmitted from the clutch ring 11 to the rotary volume 12 via the rotating plate 17. Therefore, when the player holds the face cover 9 with his / her palm and presses the fingertip against the finger holder 10a to rotate the rotating operation body 10, the clutch ring 11 splined inside the rotating operation body 10 is connected. The rotation rotates integrally, and the rotation is transmitted to the rotary volume 12 via the friction coupling portion of the clutch ring 11 and the rotating plate 17 which are power transmission paths. As a result, a detection signal corresponding to the amount of rotation operation of the rotation operation body 10 is output from the rotary volume 12, and the motor is stored in the tray 5 by controlling the motor of the launching device based on this detection signal. The game ball is fired toward the game area of the game board 3 with a launch intensity corresponding to the turning amount of the turning operation body 10. Further, since the torsion spring 18 is stored with the turning operation of the turning operation body 10, when the turning operation force on the turning operation body 10 is removed, the turning operation body 10 and the clutch ring are removed. 11, the rotary plate 17 and the rotary volume 12 are automatically returned to the positions before the operation by the elastic force of the torsion spring 18.

  On the other hand, as shown in FIG. 9, when the foreign matter 16 such as a coin is inserted into the gap S and the clutch ring 11 moves to the retracted position, the clutch ring 11 is separated from the flange portion 17 c of the rotating plate 17. To the rotary volume 12 is interrupted. As a result, the rotary volume 12 and the rotary plate 17 are automatically returned to the initial position by the resilient force of the torsion spring 18, so that the output of the rotary volume 12 becomes zero and the launch of the game ball stops. Since the rotary volume 12 automatically returns to the initial position when the foreign object 16 is sandwiched in the gap S in this way, the player must manually operate the rotary operation body 10 to maintain the optimal firing angle. In other words, it is possible to prevent an illegal act of playing with the foreign object 16 being sandwiched and the rotational operation body 10 being fixed.

  In the second embodiment, the torsion spring 18 wound around the front shaft portion 17a of the rotating plate 17 is used to automatically return the rotary volume 12 and the rotating plate 17 to the initial positions. Instead of the spring 18, a rotary volume with a self-return function incorporating a return spring may be used, or both may be used in combination.

  In the second embodiment, a frictional force is generated between the clutch ring 11 and the rotary plate 17 by friction coupling, and the rotation of the clutch ring 11 is transmitted to the rotary plate 17 only by this frictional force. However, by forming an uneven portion on the contact surface between the clutch ring 11 and the rotary plate 17, more reliable power transmission may be performed using both the frictional force and the uneven engagement force.
