Description

[Detailed Description of the Invention] This invention relates to a ball launcher for a pachinko machine,
In particular, magnets that reciprocate are installed between the batting mallet and the receiving part, so that the batting mallet fires a ball that is supplied to the firing rail when the ball is fired, and the repulsive force of the magnet catches and stops the batting mallet without making an impact sound. Therefore, the receiving part does not wear out, and the tension force of the traction spring of the batting mallet can be made smaller than before, and the tension force of the traction spring can also be changed to change the spacing between the opposing magnets. To provide a batting mallet receiving device capable of adjusting the final hitting position of the batting mallet.

In conventional pachinko machines, as shown in FIG. 4, the ball hammer 1 is rotated to the ball firing position, and each time a ball is fired, it is caught by the rubber material 22 of the catch fitting 21.
In particular, in the case of an electric type, it is necessary to hit the ball hammer with some force against the rubber material in order to generate an impact sound by the continuous hitting operation of the ball hammer and to bounce the ball with a predetermined force. For this reason, conventionally, the traction spring has been made long to make it stronger. Therefore, the rubber material tends to wear out quickly due to the strong impact of the batting mallet, and it is necessary to adjust the movement of the rubber material or reinforce the rubber material, and the hammer portion 1a at the upper end of the batting mallet slightly protrudes into the firing rail B. Disadvantages include the fact that the protruding range of the mallet cannot be changed even if the rotation angle of the handle is changed and the tensile force of the traction spring is increased, as the mallet is caught by the rubber material at the position where the handle is rotated and cannot advance beyond that point. It was hot.

This invention has been made to eliminate the above-mentioned conventional drawbacks, and its gist is to provide a ball launching device for a pachinko machine with magnets that repel each other between a batting mallet and a receiving portion that receives the batting mallet. They are provided facing each other, and the rotational movement of the batting mallet is received by the repulsive force of the magnet after the ball is fired at the time of impact without colliding with the receiving part. To provide a ball mallet receiving device for a pachinko machine which can change the protrusion range.

The present invention will be explained below based on embodiments shown in the drawings.

As shown in FIGS. 1 to 3, 1 is a ball hammer, which is pivotally supported on a board 2 attached to the back of the pachinko machine.
A receiving part 3 that receives the ball mallet 1 near the firing position
is provided on the base plate 2, and by rotating the handle 4, the motor 5 is driven to rotate the cam 6, and the batting mallet 1 is pulled down against the traction spring 7, and when the engagement with the cam 6 is disengaged, the traction spring is released. In a batting ball launcher that makes a batting mallet bounce with a force of 7, magnets 8 and 9 that repel each other are provided in the batting mallet 1 and the receiving part 3 to face each other, and the batting ball A is fired by the bouncing action of the batting mallet. The ball is fired, and the rotational movement of the batting mallet 1 is received by the repulsive force of the magnets 8 and 9.

The position where the rotational movement of the ball hammer 1 is received, that is, the final hitting position is determined by the pulling force of the traction spring 7, which pulls the ball hitting mallet 1 toward the receiving side, and the tensile force of the traction spring and the repulsive force of the magnet. . Therefore, the length by which the mallet portion 1a at the upper end of the ball striking mallet 1 projects into the firing rail B is also determined by the repulsive force of the magnets 8 and 9 and the tensile force of the traction spring.

In addition, as a means for adjusting the amount of protrusion of the mallet portion 1a of the ball striking mallet 1 into the firing rail B, in the embodiment, a receiving portion 3 is used.
This can also be done by making the magnet 9 slidable on the support frame 10 and adjusting the forward and backward movement of the magnet 9 and fixing it with a rear screw 11.

In the figure, reference numeral 12 denotes a bearing portion of the batting mallet, and 13 denotes an operating arm of the batting mallet, which is provided with a roller 14 at its tip, and the operating arm is actuated via the roller 14 by the rotation of the semicircular cam 6. 15 is a protrusion on which the traction spring 7 is applied, 16 is a tension adjustment device for the traction spring, and 17 is a traction rope, which is connected to the pulley 1 on the handle shaft.
8 and one end of the tension adjustment device 16, and the tension of the traction spring 7 is adjusted by pulling one end of the tension adjustment device according to the rotation angle of the handle 4.

According to the above-mentioned ball batting mallet receiving device of the present invention, the mallet portion at the upper end of the batting mallet protrudes into the opening of the batting ball launch rail when the batting mallet is activated to strike and fire the batted ball,
In addition, since the batting mallet can be received by the repulsive force of the magnet without directly hitting the receiving part, there is no impact noise, and especially with electric batting mallets, the bullets are continuously fired. Noise can be prevented, and there is no wear on the receiving part.

In addition, the spacing between the two magnets and the amount of protrusion from the opening of the ball launching rail is determined by the repulsive force of both magnets and the tension of the traction spring. This allows the ball to be received at the desired position without the magnets hitting each other, and the amount of protrusion of the mallet from the opening of the ball launch rail and the strength of the force of the traction spring to pull the ball to the ball can be adjusted. , the player slightly adjusts the tension of the traction spring by turning the electric handle to adjust the amount of protrusion of the batting mallet from the opening of the mallet and the rotating speed of the batting mallet to change the rebound force of the ball. I can do it.

Furthermore, since the amount of protrusion of the hammer part of the ball mallet from the opening of the ball launch rail can be adjusted, the tension of the spring is higher than that of conventional models that change only the tension of the traction spring to change the elastic force of the ball. Even if the speed is made weaker, the firing speed of the ball can be maintained at the same speed as before, and therefore, many unique effects can be achieved, such as making the handle easier to operate.
