DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine that changes the firing speed of a pachinko ball by adjusting the degree of extension of a firing spring in accordance with the turning operation of an operating handle. The present invention relates to a firing speed adjusting device to be set.

[0002]

2. Description of the Related Art A conventional ball launching device for a pachinko machine is shown in FIG.
As shown in the figure, a hammer 4 for hitting a pachinko ball, an operating handle 5 operated by a player, and a hammer 4 between the hammer 4 and the operating handle 5 via a handle wire 8 and a spring wire 7. And a firing speed that winds the handle wire 8 or the spring wire 7 and adjusts the length of the wires 7, 8 to change the degree of extension (strength) of the firing spring 6. An adjusting device 9 is provided.

The hammer 4 has an arm 42 to which a roller 41 is attached at the rear end, and a cam 43 connected to a rotating shaft 44 of a motor with a speed reducer engages with the roller 41 so that the hammer 4 is moved. It is configured to be driven by repulsion. When the player operates the operation handle 5, the motor with the speed reducer
It is configured to start driving by a switch that works in conjunction with. Reference numeral 45 denotes a rubber stopper.

The firing speed adjusting device 9 is rotatably fitted to a pivot 91 implanted on a substrate, and includes an engaging projection 92 for fixing a rear end of the spring wire 7 and a spring wire 91.
A pulley 93 around which the wire 7 is wound over a fixed angle range, and an adjusting knob 95 fitted on a pivot 94 implanted on the pulley 93 are formed. One end of the handle wire 8 is provided around the outer periphery of the adjusting knob 95. The extension 96 (strength) of the firing spring 6 can be freely changed by adjusting the length of the handle wire 8 to be wound by turning the adjustment knob 95 by being connected with the adjusting knob 95.

[0005]

However, in a conventional launching speed adjusting device of a ball launching device of a pachinko machine, a shaft 94 adjusting knob 95 implanted in a pulley 93 on which a spring wire 7 is hung is fitted. Since it is formed, the axial dimension from the substrate to the tip of the adjustment knob 95 becomes large, so that the entire firing speed adjustment device becomes large.
When the 95 is rotated, the position of the adjustment knob 95 is also rotated together with the pulley 93, making it difficult to adjust.

The present invention has been conceived in order to solve such a problem. The present invention has been made to reduce the overall thickness and to provide a pulley for applying a spring wire 7 or a handle wire 8 and a firing speed adjusting device. Are separated so that the installation positions of the two have flexibility.

[0007]

According to the present invention, there is provided a pachinko ball firing speed adjusting apparatus, comprising: a hammer 4 for driving a pachinko ball;
In a pachinko machine having an operating handle 5 operated by a player, and a hammer 4 and a firing spring 6 for urging the hammer 4 in one direction via a wire between the hammer 4 and the operating handle 5, the wire is wound. A firing speed adjusting device 9 for adjusting the length of the wire to change the degree of extension of the firing spring 6, a fan-shaped pulley 11 rotatably fitted to a pivot 21 implanted in the substrate 2, A pivot 14 fixed to the eccentric position of the fan-shaped pulley 11 and a knob fitted to the pivot 14
12, a rotation restrictor 13 and a pivot 14 formed on the knob 12.
Means for adjusting the engagement angle between the knob 12 and the pivot 14 by engagement with a fixed disk 15 formed on the fan-shaped pulley 11 and the knob 12, the spring-side wire 7 and the handle Each end of the wire 8 is connected to each other.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the front view of FIG. 1, the present invention relates to a hammer 4 having a hitting portion for hitting a pachinko ball at its tip, an operating handle 5 provided on a game board and operated by a player. The hammer 4 is connected between the hammer 4 and the operating handle 5 between the pulley 3 rotatably fitted to the pivot 22 implanted on the base plate 2 and the handle wire 8 and the spring wire 7. In a ball launching device of a pachinko machine having a launching spring 6 for urging in one direction, a spring wire 7 is rotatably fitted to a pivot 21 implanted in the substrate 2.
The firing speed adjusting device 1 that adjusts the length of the firing spring 6 to change the degree of extension (strength) of the firing spring 6 is provided.

As shown in the assembly drawing of FIG. 2, the firing speed adjusting device 1 has a hole 20 fitted into a pivot 21 implanted in the substrate 2.
, A knob 12 rotatably fitted to a pivot 14 fixed at a position eccentric to the fan-shaped pulley 11 by screws 19, and a rear end of the handle wire 8 fixed. And a spring wire fixing member 18 provided on the outer periphery of the knob 12 and fixing one end of the spring wire 7.

As shown in the sectional view of FIG. 3, a rotation restrictor 13 composed of a large number of protrusions is formed on the inner periphery of the upper portion of the adjustment knob 12, and further, on the inner side of the lower portion of the adjustment knob 12, Step
The pivot 14 is formed integrally with a fixed disk 15 having a number of projections that engage with the rotation restrictor 13 of the adjustment knob 12.

Since a spring 16 fitted on a pivot 14 exists between the step 10 of the adjusting knob 12 and the pulley 11, the rotation restrictor 13 of the adjusting knob 12 is attached to the fixed disk 15 of the pivot 14. They are pressed so that they are always engaged.

When adjusting the impact force of the hammer 4, when the adjustment knob 12 is pushed in against the elasticity of the spring 16, the engagement between the rotation restrictor 13 and the fixed disk 15 is released, and the adjustment knob is adjusted. Since the knob 12 can be rotated, the adjusting knob 12 is rotated to change the winding length of the spring wire 7 to adjust the degree of extension (strength) of the firing spring 6. When the adjustment knob 12 is lifted after the adjustment is completed, the rotation restrictor 13 and the fixed disk 15 are engaged, and the adjusted state is maintained.

When the player turns the operation handle 5,
When the motor with the reduction gear is started, the cam 43 rotates, and each time the cam 43 rotates, the cam 43 engages with the roller 41 of the hammer 4, and the hammer 4
To launch pachinko balls continuously. By changing the rotation angle of the operation handle 5, the degree of extension of the firing spring 6 changes via the handle wire 8 and the spring wire 7, so that the firing speed of the pachinko ball can be adjusted.

[0014]

As is clear from the description based on the above embodiment, according to the firing speed adjusting device of the present invention, the dimension along the axial direction of the pivot can be reduced, so that the overall thickness is reduced. It has the effect that it can be done.
