Oscillation is restricted in the clockwise direction in FIG. 3 centering on 34a. In the vicinity of the support shaft 34a of the hitting ball 34, on the opposite side (left side in FIG. 3) to the connecting side of the adjusting spring member 33, an extending portion 34b is extended outward. A firing motor 35 is disposed in the vicinity of 34b. The firing motor 35 is used to apply power for hitting the game ball B to the hitting ball 34 and to play an extension 34b of the hitting ball 34 on its rotation shaft (not shown). The firing cam 36 is fixed. The firing motor 35 is configured such that when the player touches the handle ring 24 and a single switch 56 described later is turned off, the rotation shaft thereof can rotate at approximately 100 rpm (100 rotations per minute). The firing cam 36 is rotated based on the rotation of the rotating shaft.

  The firing cam 36 drives the firing motor 35, that is, pushes the extended portion 34 b of the hitting ball 34 downward with the rotation of the rotation shaft thereof, thereby causing the adjusting spring member 33 to move the adjusting ball member 34. The ball is repelled in the counter-biasing direction (left side in FIG. 3) to recoil the upper end of the hitting ball 34 in the biasing direction (right side in FIG. 3) by the adjusting spring member 33. A substantially crescent-shaped protrusion 36a protruding outward is provided. The protruding portion 36a protrudes toward the extending portion 34b of the hitting ball rod 34 described above, and the extending portion 34b described above extends at a portion that intersects with the rotation track of the protruding portion 36a.

  According to the gaming ball launching apparatus 20 configured as described above, the launch cam 36 is rotated in the clockwise direction in FIG. 3 as the rotation shaft of the launch motor 35 is rotated, and the hitting basket 36 is rotated along with the rotation. The extended portion 34 b of 34 is pushed downward by the projection 36 a of the firing cam 36.

When the firing cam 36 is further rotated by the firing motor 35 and the projecting portion 36a is disengaged from the extending portion 34b, the striking ball 34 is recoiled by the biasing force (restoring force) of the adjusting spring member 33 so that it returns to its original state. By the reaction of the hitting ball 34, the game ball B is hit and fired.

  On the other hand, when the shaft 23 is rotated by the rotation operation of the handle ring 24 of the handle 21, the pulley 31 is rotated and the wire 32 is pulled toward the pulley 31 arrangement side (left side in FIG. 3). As the wire 32 is pulled, the swinging member 33a is tilted in the direction in which the wire 32 is pulled. On the other hand, as the swinging member 33a is tilted, the adjusting spring member 33 is disposed on the side where the hitting ball 34 is disposed. It is pulled and extended in the opposite direction. That is, by adjusting the amount of rotation of the handle ring 24, the pulling amount (deformation amount) of the adjusting spring member 33 is changed and adjusted. As a result, the biasing force of the adjusting spring member 33 that biases the hitting ball rod 34 is reduced. It can be adjusted. By adjusting the urging force of the adjusting spring member 33, the hitting force of the game ball B by the hitting ball rod 34 is adjusted, and the firing speed of the game ball B hit by the hitting ball rod 34 and the game area 5a are adjusted. The flying amount of the game ball B launched toward the player can be adjusted.

Yes. The pair of regulating walls 73 are predetermined in the biasing direction of the pressing spring 71 from the contact surface of the pressing plate 72 and the claw portion 63 in the state where the handle ring 24 is in the basic position, that is, in the state shown in FIG. It protrudes at a position shifted by an angle W1.

  When the handle ring 24 is rotated from the basic position by a predetermined angle W1 or more, the game ball launching device 20 increases the pulling amount of the adjustment spring member 33 described above, and uses the biasing force of the adjustment spring member 33. The striking force of the striking ball 34 that strikes the game ball B is configured so that the gaming ball B hit by the striking ball 34 is strong enough to reach the game area 5a. That is, the striking force of the striking ball 34 that strikes the game ball B is configured to be greater than the resistance force applied when passing through the guide passage 10.

  According to the pair of regulating walls 73 configured as described above, the sliding amount of the pressing plate 72 biased by the pressing spring 71 can be limited (see FIG. 6B). That is, the pair of regulating walls 73 regulate the sliding of the pressing plate 72 when the handle ring 24 is rotated from the basic position by a predetermined angle W1 or more, and the claw portion 63 of the switch button 57 by the pressing plate 72 is controlled. Pressing can be prohibited. For example, as shown in FIG. 6B, when the handle ring 24 is rotated by a predetermined angle W1 or more, the pressing plate 72 biased by the pressing spring 71 is regulated to slide by a pair of regulating walls 73. The pressing of the claw portion 63 of the switch button 57 by the pressing plate 72 can be released.

  As shown in FIG. 6B, when the pressing by the pressing plate 72 is released, the pressing portion 62 of the switch button 57 is urged by the restoring force of the movable contact 59 of the single switch 56, and the shaft hole 64. Is tilted clockwise in FIG. 6B. By such tilting of the switch button 57, the movable contact 59 of the single switch 56 is separated from the fixed contact 60, so that the single switch 56 can be turned off and the driving of the firing motor 35 can be started. That is, the game ball launching device 20 can start launching the game ball B toward the game area 5a. Further, in this state, for example, when the player presses the pressing portion 61 of the switch button 57, the driving of the firing motor 35 is stopped, while when the player releases the pressing of the pressing portion 61, the firing is performed. The drive of the motor 35 is resumed. Therefore, by repeating the operation of pressing and releasing the pressing portion 61 of the switch button 57, it is possible to fire the game balls B one by one (one shot).

  Even when the handle ring 24 is rotated by a predetermined angle W1 or more, the switch button 57 is rotated in the opposite direction in FIG. 6B through the shaft hole 64 when the operation portion 61 is pressed. It can be tilted clockwise. As the switch button 57 is tilted, the movable contact 59 of the single-shot switch 56 is pressed toward the fixed contact 60 by the pressing portion 62, and both the contacts 59, 60 can be short-circuited. That is, the single-shot switch 56 is turned on to stop the driving of the launch motor 35, and the launch of the game ball B toward the game area 5a by the game ball launch device 20 can be stopped.

  Next, the operation of the game ball launcher 20 configured as described above will be described. First, when the handle ring 24 is rotated from the basic position in the direction of arrow A in FIG. 6, the pulley 31 fixed to the shaft 23 is rotated, and the wire 32 moves to the pulley 31 arrangement side (left side in FIG. 3). Pulled towards. As the wire 32 is pulled, the swinging member 33a is tilted in the direction in which the wire 32 is pulled. On the other hand, as the swinging member 33a is tilted, the adjusting spring member 33 is disposed on the side where the hitting ball 34 is disposed. It is pulled and extended in the opposite direction. That is, by adjusting the rotation amount of the handle ring 24, the pulling amount of the adjusting spring member 33 is changed, and as a result, the biasing force of the adjusting spring member 33 that biases the hitting ball rod 34 can be adjusted. is there.

  In such a case, the switch button 57 is pressed through the shaft hole 64 when the claw portion 63 is pressed by the pressing plate 72 urged by the restoring force accompanying the compression deformation of the pressing spring 71. 6 (a) is tilted counterclockwise. By the tilting of the switch button 57, the pressing portion 62 presses the movable contact 59 of the single switch 56 toward the fixed contact 60, and the both contacts 59, 60 are short-circuited. For this reason, the single switch 56 is turned on, and the driving of the firing motor 35 is stopped. That is, the launching of the game ball B toward the game area 5a by the game ball launching device 20 is stopped.

  Thereafter, when the handle ring 24 is further rotated and is rotated by a predetermined angle W1 from its basic position, the pulling amount of the adjustment spring member 33 is increased, and the game ball B is utilized using the biasing force of the adjustment spring member 33. The striking force of the hitting ball 34 that hits the ball becomes a strength with which the game ball B hit by the hitting ball 34 can reach the game area 5a. On the other hand, the pressing plate 72 biased by the pressing spring 71 is restricted from sliding by the pair of regulating walls 73, and the pressing of the claw portion 63 of the switch button 57 by the pressing plate 72 is released. When the pressing by the pressing plate 72 is released, the pressing portion 62 of the switch button 57 is urged by the restoring force of the movable contact 59 of the single switch 56, and the timepiece in FIG. Tilt in the direction. By such tilting of the switch button 57, the movable contact 59 of the single switch 56 is separated from the fixed contact 60, and the single switch 56 is turned off. When the single switch 56 is turned off, the driving of the firing motor 35 is started and the rotation of the firing cam 36 is started.

  The firing cam 36 is rotated in the clockwise direction in FIG. 3 along with the rotation of the rotation shaft of the firing motor 35. With this rotation, the extension 34b of the hitting ball 34 is lowered by the projection 36a of the firing cam 36. Is pressed toward. When the extending portion 34b is pressed by the protrusion 36a, the upper end portion of the hitting ball 34 is tilted in the counter-biasing direction (left side direction in FIG. 3) against the biasing force of the adjustment spring member 33. . When the firing cam 36 is further rotated by the firing motor 35 and the projecting portion 36a is disengaged from the extending portion 34b, the striking ball 34 is recoiled by the biasing force (restoring force) of the adjusting spring member 33 so that it returns to its original state. By the reaction of the hitting ball 34, the game ball B is hit and fired. The game ball B hit by the hitting ball 34 passes through the guide passage 10 and is driven upward to the game area 5a.

  As described above, according to the pachinko machine 1 of the present embodiment, the transmission device 70 of the game ball launching device 20 has the pair of regulating walls 73 when the handle ring 24 is rotated by a predetermined angle W1 or more. The switching operation of starting the driving of the firing motor 35 can be performed by releasing the pressing of the claw portion 63 on the switch button 57 by the pressing plate 72 and turning off the single switch 56. In addition, the game ball launching device 20 increases the amount of tension of the adjustment spring member 33 when the handle ring 24 is rotated by a predetermined angle W1 or more from the basic position, and the hit ball urged by the adjustment spring member 33. The striking force of the heel 34 can be set to a strength that allows the game ball B to reach the game area 5a. Therefore, the striking ball 34 to which power is applied by the launch cam 36 rotated by the launch motor 35 cannot resist the resistance force applied when the game ball B passes through the guide passage 10, and is downstream of the guide passage 10 (see FIG. It is possible to prevent the ball from falling from the upper side (1 upper side) to the upstream side (lower side in FIG. 1) and to reliably drive the game ball B into the game area 5a.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in this embodiment, the striking force of the hitting ball rod 34 is adjusted by changing the amount of tension of the adjusting spring member 33 formed by a tension spring. However, the adjustment spring member that adjusts the striking force of the hitting ball rod 34 is not necessarily a tension spring member, and may be formed of, for example, a compression spring member. That is, when the adjusting spring member is formed of a compression spring, the striking force of the hitting ball 34 can be adjusted by changing the compression amount of the adjusting spring member.

  In this embodiment, by adjusting the rotation amount of the handle ring 24 of the handle 21, the pulling amount of the adjusting spring member 33 is changed to adjust the striking force of the striking ball 34, while rotating by the firing motor 35. The present invention has been described using the game ball launcher 20 that launches the game ball B by driving the hitting ball 34 with the launch cam 36. However, as a driving device for applying a striking force to the striking ball, a stroke type solenoid in which a plunger (striking ball) energized by a spring upon receiving power supply from a power supply device performs a sliding motion, or a spring The present invention may be applied to a game ball launcher using a rotary solenoid in which a biased plunger swings.

  For example, in a game ball launcher using a stroke type solenoid, the plunger is slid in the counter-biasing direction against the biasing force of the spring by the start of power supply by the power device, while the power supply is temporarily stopped. As a result, the plunger is recoiled in the urging direction by the urging force of the spring. The game ball is hit by the reaction of the plunger. In addition, in a game ball launcher using a rotary solenoid, the plunger swings a predetermined angle in the counter-biasing direction against the biasing force of the spring by the start of power supply by the power device, while the power supply is temporarily stopped. As a result, the plunger is rebounded in the urging direction by the urging force of the spring. The game ball is hit by the reaction of the plunger.

  According to such a game ball launcher using a solenoid, the amount of electric power (current amount) supplied to the solenoid is adjusted by adjusting the amount of rotation of the handle ring of the handle, and according to the change in the amount of electric power. Thus, the impact force of the plunger can be adjusted.

Hereafter, the modification of this invention is shown. 2. The bullet ball game machine according to claim 1, wherein the drive device counteracts the urging member that urges the striking ball toward the game area and the batted ball that is urged by the urging member. A power supply device that applies a striking force to the striking ball by flipping in the biasing direction, and the operation handle changes a deformation amount of the biasing member to change the striking force of the striking ball.
