Description

[Detailed description of the invention] The present invention relates to a ball striking force adjustment mechanism in a ball firing device of a pachinko game machine, and more specifically, to a ball firing device of an automatic ball hitting type pachinko game machine using a rotary solenoid, which has been widely known in recent years. , equipped with a batting rod retraction angle adjustment mechanism that limits the retraction angle of the batting rod by bringing the batting rod into contact with a stopper made of a buffer member that moves linearly in conjunction with the rotation of the operating handle. It is an object of the present invention to provide a ball hitting force adjustment mechanism that can adjust the ball hitting force extremely easily and reliably by adjusting the ball hitting force by adjusting the ball hitting force.

Another purpose of this invention is to maintain a constant hitting force by adjusting the torque of the rotary solenoid as appropriate, even if the torque of the rotary solenoid increases or decreases due to fluctuations in the power supply voltage due to differences in the number of machines used in a store or in different areas of use. The object is to provide a ball hitting force adjustment mechanism.

An embodiment of the ball striking force adjustment mechanism of the present invention will be described below with reference to the drawings.A ball firing device 1 located on the front frame of a pachinko game machine has a rotary solenoid 3 and an operation handle 4 integrally assembled to a base 2. This is what happens.

A ball batting rod 6 is attached to the corner shaft at the end of the rotating shaft 5 of the rotary solenoid 3, and is fastened with a nut, and electricity is applied to the rotary solenoid 3 from a control pulse circuit (not shown). It oscillates periodically depending on the signal,
A ball hitting spring 7 fixed at the tip of a ball hitting rod 6 hits a pachinko ball a positioned at the lower end of a pachinko ball launching rail 8.

The receding angular position of the ball hitting rod 6 is limited by a stopper 12 made of a buffer member fixed to one end of a rack 11 which is meshed with a pinion 10 pivotally attached to the operating handle shaft 9.

A return spring 13 for rotating the operating handle 4 in the return direction is provided at the other end of the rack 11, and a long hole 15 drilled in the rack 11 is inserted into a protruding shaft 14 protruding from the base 2.
The rotation range of the operating handle 4 is limited to an angle range that is easy to operate.

Note that 16 in the figure is a stopper for the ball hitting rod 6 made of a rubber member.

The ball launcher 1 configured as described above is such that when the operating handle 4 is rotated, the rotary solenoid 3 is periodically driven to cause the ball hitting rod 6 to swing. A rack 1 that meshes with the pinion 10 via a pinion 10 that is attached to a shaft 9.
1 gradually retreats, and the contact angle between the stopper 12, which is a buffer member fixed to the tip of the rack 11, and the ball batting rod 6 increases. It is possible to change the hitting power when hitting ball a.

Since the stopper 12 is made of a cushioning member such as rubber, the impact force when the ball hitting rod 6 hits the stopper 12 can be absorbed as much as possible, and the impact force transmitted to the operating handle 4 is extremely small. Since the transmission mechanism of the rack 11 moves the stopper 12 forward and backward, the player's force can be reduced.
Operation is also extremely simple and reliable.

In addition, since the torque of the rotary solenoid 3 fluctuates depending on the voltage, the lower or upper limit of the ball hitting force adjustment range of the operating handle 4 may be insufficient depending on the region where the voltage is high or low. By changing the engagement position of 11, the operating handle 4
and the relative position of the stopper 12 can be changed.

Therefore, in the present invention, by changing the starting position of the ball hitting rod 6 and the meshing position of the pinion 10 and rack 11 in response to voltage fluctuations, the rotation angle of the operating handle 4 and the ball hitting force can be adjusted very easily. .

As explained above, the ball hitting force adjustment mechanism of the pachinko game machine of the present invention limits the receding angle position of the ball hitting rod with a stopper made of a buffer member that moves linearly in conjunction with the rotation of the operating handle. , which reduces the collision impact of the batting rod and allows adjustment operations to be performed easily and reliably.

Furthermore, it has the feature that it is possible to obtain an appropriate batting force corresponding to the range of action of the operating handle at all times regardless of fluctuations in power supply voltage due to facility conditions, and the practical effects of the present invention are extremely large.
