Description

  The present invention relates to a ball striking force adjusting handle in a ball ball game machine that is arranged in front of a ball ball game machine and adjusts the ball striking force of a ball hit from a hit ball launching unit onto a game board surface.

  Conventional hitting force adjusting handles of pachinko gaming machines, which are a kind of ball game machines, in particular, touch switch type are as follows. That is, the hitting force adjusting handle includes a proximal-side grip portion attached to the game board mounting frame, a distal-end cap portion, and an operation lever interposed between the grip portion and the cap portion. Generally composed. A main shaft that protrudes toward the proximal end is attached to the center of the operation lever, and the main shaft is inserted into a shaft hole provided in the grip portion and a pulley is attached to the end portion. The pulley is hooked with a wire connected to an elasticity adjuster for adjusting the hitting force of the hitting ball by the heel, and the main shaft is rotated by rotating the operation lever to one side.

Guided to the side. The variable resistor 18, the micro switch 28, the touch switch 34, the motor 53, and the LED 62 are all electrically controlled. For example, although illustration is omitted, when the touch switch 34 is actuated, a rotary solenoid (not shown) for striking the hit ball into the game portion 2a on the game board 2 reciprocates, and the hit ball positioned at the hit ball launching portion is continuously moved. Will be launched.

Therefore, when the player is not touching the ball striking force adjusting handle 7, the connecting member 36 (36a) comes into contact with the upper edge of one arcuate hole 46a as shown in FIG. It has stopped. Further, as shown in FIG. 8 (a), one tooth group 16 a of the annular large-diameter step portion 15 a provided on the outer peripheral surface of the shaft tube member 14 interlocked with the operation lever 10, and the slave shaft tube member 19. One tooth portion group 22a of the annular small-diameter step portion 20b meshes with each other at its center portion.

  In this state, when a player sits on the front surface of the pachinko gaming machine P, stores the game ball in the ball tray 6 and touches the operation lever 10, the touch switch 34 is actuated to move the shot ball located at the ball hitting unit to the game board. A rotary solenoid (not shown) for driving into the two game units 2 repeats the reciprocating operation, and the hit balls in the hit ball emitting unit are shot one by one toward the game unit 2a. Then, in order to adjust the hitting force, the operation lever 10 is rotated by a predetermined amount in the clockwise direction as shown in FIG.

Accordingly, one tooth group 16a of the annular large-diameter step portion 15a of the receiving recess 12 of the shaft cylinder member 14 and one of the slave annular small-diameter step portion 20b of the slave cylinder member 19 as shown in FIG. Engagement with the tooth group 22a is completed, and the tooth group 17 of the annular small-diameter step portion 15b of the shaft cylinder member 14 and the tooth group 21 of the slave annular large-diameter step portion 20a of the slave cylinder member 19 are engaged. Further, when the amount of rotation is increased, as shown in FIG. 8B, the other tooth group 16b of the annular large-diameter step portion 15a of the shaft cylinder member 14 and the slave annular small-diameter step portion 20b of the slave cylinder member 19 are provided. And the other tooth portion group 22b of each other. In any of these cases, the operating lever 10 is urged counterclockwise in FIG. 8A by the torsion coil spring 74, and at the same time, the driven cylinder member 19 is urged clockwise.

In the present invention, a pair of tooth groups 16a and 16b provided on the annular large-diameter step portion 15a of the shaft cylinder member 14 and a pair of tooth portion groups 22a and 22b provided on the slave annular small-diameter step portion 20b of the slave cylinder member 19. And the tooth portion group 17 provided on the annular small diameter step portion 15b of the shaft cylinder member 14 and the tooth portion group 21 provided on the slave annular large diameter step portion 20a of the shaft cylinder member 19 are engaged with each other. Moreover, the tooth group 17 provided on the annular small-diameter step portion 15b of the shaft cylinder member 14 and the tooth group 21 provided on the slave annular large-diameter step portion 20a of the slave cylinder member 19 are set with high accuracy in meshing state. ing. This is due to the following reason.

That is, when the control lever 10 is rotated to adjust the hitting force of the hit ball, when the hit ball is hit weakly and the hit ball only reaches the front side of the game portion 2a on the two game boards, the hit ball is hit strongly. When the hit ball reaches the back side of the game unit 2a, there are few opportunities for the hit ball to win. On the other hand, there are many opportunities to win when the hit ball reaches the upper center of the game part 2a. Therefore, since the player usually determines the rotation angle of the operation lever at the intermediate position portion, the tooth portion group 17 provided on the annular small-diameter step portion 15b of the axial tube member 14 with improved accuracy is provided within that range. And the toothed portion group 21 provided on the driven annular large-diameter step portion 20a of the driven shaft cylinder member 19 are engaged with each other to facilitate fine adjustment of the operation lever 10 angle.

  Further, during a game, when a special gaming state advantageous to the player, for example, a big hit state, each LED 62 on the side surface of the second wiring board 55 or the LED 62 on the tip of the support rod 61 is lit or blinked, and the motor 53 is driven to rotate the shielding member 65 at the tip of the motor shaft 53a. As a result, the light stagnating in these changes is transmitted through the cap main body 9a and emitted from the player's hand. Thereby, it becomes a state such as a big hit, and it is possible to encourage the player's heart and satisfaction, and to enhance the interest of the game.

  As described above, the present invention is provided with the shaft cylinder member 14, which is a cylindrical shaft cylinder portion whose base end side and distal end side are opened at the center of the operation lever 10, the short support cylinder portion 43, and the holding cylinder portion 44. A bearing recess 12 having a through hole 13 communicating with the inside of the shaft tube portion is provided in the partition wall 11 in the portion 8 so that the proximal end side of the shaft tube portion is rotatably fitted. Further, the contact terminal 34a, which is an electrical component on the distal end side of the operation lever 10, and the electrical wirings 42d and 42e drawn from the second wiring board 55 are inserted into the central cylindrical portion of the operation lever 10 to hold the gripping portion on the proximal end side. It was led to 8. Thereby, even if the operating lever 10 is rotated, the electric wires 42d and 42e do not contact and rub against the inner peripheral edge as when inserted into the arc-shaped holes 46a and 46b, and the operating lever 10 rotates. It will be arranged without being influenced by. Therefore, it is possible to eliminate the risk of a short circuit accident or a disconnection accident due to the covering layer of the electrical wirings 42d, 42e being peeled off regardless of the turning operation of the operation lever 10.

In addition, although the tooth portion group is provided as an interlocking means between the shaft cylinder member and the driven cylinder member, the present invention is not limited to this, and other means such as a belt spanned between the shaft cylinder member and the driven cylinder member are used. Also good. In addition, either a type of ball game machine that fires a ball hitting the ball hitting part by a spear or a type of ball ball game machine that hits a ball hitting the ball hitting part by a rotary solenoid as in the present invention The present invention is also applicable.

FIG. 3 is a perspective view of a hitting force adjusting handle according to the present invention. The disassembled perspective view of a holding part. The exploded perspective view of an operation lever. The disassembled perspective view of a cap part. The perspective view of a shaft cylinder member and a follower cylinder member. The plane sectional view of the attachment state of the hitting force adjustment handle. (A) and (B) are explanatory views showing the operation of the operation lever.
