Description

  The present invention relates to a launching device for a gaming machine that launches a pachinko ball for gaming that has been thrown into the gaming machine onto a gaming board.

A launch device of a gaming machine is for launching a game ball supplied from a ball feeding device, and mainly includes a launch handle, a handle shaft, a spring, a drive motor, a hitting hammer, and the like. In general, in a long-time game, the handle is often felt to be heavy and tired. As measures for this, there are inventions (Patent Documents 1 to 3) in which a handrest of the launching handle is provided without changing the spring mechanism, and inventions (Patent Document 4) that reduce the feeling of fatigue by modifying the launching handle itself. Has been made. In addition, there are an invention (Patent Document 5) in which the handle rotation direction is both directions, and an invention (Patent Document 6) in which the firing intensity is changed by a computer.
JP 2001-204900 A JP 2003-225380 A JP 2005-278833 A JP-A-8-52259 JP-A-2005-7003 JP 2006-6694 A

However, regarding the invention of providing a hand rest, the player's feeling of fatigue will be eliminated to some extent, but it does not improve the operability of the launching handle itself, and there is still a problem that the operability is not sufficient. .
Regarding the invention for changing the firing strength, Patent Document 5 aims to reduce the fatigue of a left-handed player and does not improve the spring itself of the launching device. Moreover, since patent document 6 changes the strength of the launch intensity by a computer, the operability is uncomfortable and there is still a problem in operability. In addition, there is a problem that the configuration is complicated because it is controlled by a computer.
Therefore, the present invention solves the disadvantages that the player feels that the firing handle is heavy by a simple means, and when the firing handle is released, the handle is easily returned to improve operability, It is an object to improve a player's handle operability.

The linkage mechanism 6 transmits the torsional force of the rotating ring 22 to the urging force adjusting rotating body 50 and rotates it.

  As shown in FIG. 4, the drive device 7 includes a motor 70 (shown by a dotted line in the figure) as a drive source for reciprocating the striking rod 40, an output shaft 72 to which a cam 71 is attached, a mount 73 of the motor 70, a mount And a plurality of attachment portions 74 for fixing 73 to the attachment substrate 10. The engagement pin 58 is positioned within the rotation locus range of the cam 71. A detection signal of a touch switch (not shown) by rotation operation of the rotation ring 22, or a detection signal generated by touching the stop button 20, an appropriate rotation amount signal, etc. are also detected, and this is detected as a launch control board (not shown). The motor 70 is energized and the cam 71 is driven according to the control of the substrate. When the cam 71 is rotated in the clockwise direction in FIG. 4, the engaging pin 58 is engaged and rotated with the striking rod 40 in the counterclockwise direction, and the coil spring 53 is compressed to accumulate the urging force. 4 is released from the restraint, and the striking rod 40 is repelled in the right direction in FIG. 4 by the urging force of the coil spring 53 to repel the game ball at the launch position.

  As shown in FIG. 5, the rotary shaft 8 is fixed to the rotary body 50 so as to extend in the radial direction from the rotary body 50 and so as to be orthogonal to the handle shaft 21 and the receiving shaft 31. Rotate. The rotating shaft 8 rotates in the direction opposite to the rotating direction of the rotating ring 22. As shown in FIG. 1, when the rotation ring 22 is rotated during the game, a force W in the rotation direction of the rotation shaft 8 due to gravity W applied to the weight 9 (just equal to W in FIG. 1) is rotated. At the position when the ring 22 is stopped, the gravity W is decomposed into a component force X in the direction perpendicular to the axial direction (rotation direction) and a component force Y in the axial direction component. The mounting position and the axial direction of the rotating shaft 8 are set and fixed with respect to the urging force adjusting rotating body 50 so as to be larger than the component force X.

The operation of the launching device 1 will be described with reference to FIG. During the game, the elastic device 5 intermittently repels the striking rod 40 by the engagement / disengagement of the cam by the continuous rotation of the motor 70 with the urging force being applied to the striking rod 40. . Since the player operates the rotating ring 22 during the game, a return moment B generated by the biasing force of the coil spring 53 acts on the rotating ring 22. Since the rotational moment M ₂ due to the gravity W of the weight 9 is generated in a direction opposite to the return moment B (vertically downward in FIG. 1), the return handle B of the firing handle is canceled out. Therefore, it is only necessary to hold the rotating ring 22 lightly by hand, and the player's fatigue can be greatly reduced.
When the firing is stopped, it is returned to the original position by the urging force of the coil spring 53. However, since the rotational moment M ₁ due to the gravity W of the weight 9 is smaller than that during the game, the return moment is larger than the return moment during the game. Therefore, the operability of the rotating ring 22 at the time of return is good.
