[Industrial application fields]
The present invention relates to a pachinko machine provided with a game stop mechanism that stops a game when the ball overflows an overflow bowl that guides a ball overflowing from a hitting ball supply tray to a ball storage tray.
[0002]
[Prior art]
Conventionally, a pachinko machine provided with this type of game stop mechanism is known, for example, as disclosed in Japanese Utility Model Publication No. 3-122881. As shown in FIG. 15, the game stop mechanism includes a detection lever 102 disposed in an overflow rod 101 formed on the mechanism plate 100, and a switch 103 fixed to the mechanism plate 100 corresponding to the detection lever 102. It is comprised by. The detection lever 102 is pivotally supported at its lower end by a shaft 104, and a horizontal lever piece 102a is integrally formed at the upper end. Usually, the detection lever 102 is urged by a coil spring 105, as shown by a solid line in FIG. Further, the lever piece 102a is held in a state of being drawn into the overflow bowl 101. Then, when the overflow ball 101 is filled with a ball, the detection lever 102 is pressed by the filled ball and rotates against the bias of the coil spring 105 as shown by a chain line in FIG. 102a protrudes from the cutout groove 101a of the overflow rod 101 and presses the actuator piece 103a of the switch 103 to turn on the switch 103, thereby stopping the motor for hitting the ball and preventing the game from being played. Yes.
[0003]
[Problems to be solved by the invention]
In the conventional game stop mechanism, the coil spring 105 that urges the detection lever 102 is supported by having one end of the coil spring 105 fitted into the protrusion 106 of the detection lever 102 and the other end contacting the inner surface of the side wall 101b of the overflow rod 101. Therefore, there is a problem that when the detection lever 102 is assembled, the detection lever 102 is easily detached from the detection lever 102, and when it is detached, it is difficult to jump and search due to its elasticity.
[0004]
Further, since the detection lever 102 is supported by the cover 107 attached to the upper surface of the opening of the overflow rod 101 while being supported in the overflow rod 101, the cover 107 There was a problem that when it was not installed, it would come off easily and fall off. In particular, recent pachinko machines are assembled by flow work, and the detection lever 102 and the cover 107 are often assembled in separate processes. Many situations of falling off and dropping off caused remarkably poor workability.
[0005]
The present invention has been made in view of the above-described problems of the prior art. The object of the present invention is to simplify the assembly of the detection lever and eliminate the need for a coil spring with a simple configuration. It is intended to improve workability at the time of assembly by preventing the lever from falling off the overflow rod.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a striking ball supply tray for receiving a ball discharged from a prize ball dispensing device, a mechanism plate on which an overflow rod for flowing down a ball overflowing from the striking ball supply tray, A game stop mechanism comprising a ball storage tray that receives and stores a ball that flows down through an overflow rod, a detection lever that is rotated by the ball filled in the overflow rod, and a switch that is turned on when the detection lever rotates. In the pachinko machine comprising the above, the elastic lever is used to turn and bias the detection lever to a position where the switch is not turned on.
[0007]
The detection lever is preferably provided with a rib piece that restricts the bending of the elastic piece in the pressing direction so that the elastic piece does not break.
[0008]
In order to facilitate the assembly of the detection lever, it is preferable to provide a knob on the elastic piece.
[0009]
In order to prevent the detection lever from falling off, it is preferable to provide a protrusion on the elastic piece and provide a groove hole on the overflow rod so that the protrusion can face.
[0010]
Further, for the same purpose, a blocking piece with which the elastic piece can contact may be provided inside the side wall of the overflow bottle.
[0011]
[Action]
The elastic piece formed on the detection lever is in contact with the side wall of the overflow rod when the ball is not filled with the ball and reliably urges the detection lever to a position where the switch is not turned on by the elastic force. . When the overflow ball is filled with a ball, the ball is pressed and deformed, and thereby the detection lever functions to turn on the switch.
[0012]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine according to the present invention. FIG. 2 is a rear view thereof. In the figure, 1 is a pachinko machine, 2 is a front frame of the pachinko machine, and 3 is a game board that is detachably attached to the back surface of the front frame 2. A hitting ball supply tray 4 and a ball storage tray 5 are provided below the front frame 2, and a mechanism plate 6 is mounted on the back surface of the game board 3 so as to be openable and closable.
[0013]
As shown in FIG. 2, the mechanism board 6 has a winning ball collecting portion 7 formed on the front side facing the back side of the game board 3. A premium ball tank 8 is fixed to the upper part of the back surface of the mechanism plate 6. Below the prize ball tank 8 is provided a tank rail 10 for aligning the prize balls and guiding them to the prize ball dispensing device 9. Below the prize ball dispensing device 9, a prize ball discharge rod 11 for guiding the dispensed prize ball to the hit ball supply tray 4, and when the hit ball supply tray 4 is full of prize balls, An overflow basket 12 for overflowing the surplus prize balls into the ball storage tray 5 is formed, and a game stop mechanism 13 is disposed near the lower end outlet of the overflow basket 12. A cover 14 is attached to the rear opening of the prize ball discharge basket 11 and the overflow basket 12.
[0014]
The game stop mechanism 13 is roughly constituted by a detection lever 15 and a switch 16 as shown in FIGS. The detection lever 15 is disposed in the overflow rod 12 and is pivotally supported by inserting a cylindrical portion 17 at the lower end into a shaft 18 projecting from the mechanism plate 6 and having an arc shape at the upper end. A lateral lever piece 19 is integrally formed. A stopper portion 19 a is formed at the tip of the lever piece 19. As shown in FIG. 14, the shaft 18 has a large diameter portion 18a and a small diameter portion 18b. The shaft 18 receives the tip of the cylindrical portion 17 by the large diameter portion 18a, thereby causing contact friction when the detection lever 15 rotates. I try to reduce it.
[0015]
In the present embodiment, the switch 16 has a normally open contact with a micro switch, and is fixed to the mechanism plate 6 positioned outside the overflow rod 12 so as to face the detection lever 15. The actuator piece 20 and the tip of the lever piece 19 of the detection lever 15 are provided in contact with each other. The switch 16 is connected to the power supply circuit of the ball launching motor 21. A switch cover 29 is detachably attached to the mechanism plate 6 by a locking claw piece 30.

The detection lever 15 is normally urged to rotate to a position where the switch 16 is not turned on by the coil spring when the ball in the overflow rod 12 is not full. 3 to 5, a slender elastic piece 22 is integrally formed of synthetic resin at the lower end of the lever piece 19 of the detection lever 15, and the elastic piece 22 is applied to the inner surface of the side wall 12a of the overflow rod 12. I try to contact them.
[0017]
As a result, in the normal state when the overflow rod 12 is not filled with the sphere, the detection lever 15 has the tip of the lever piece 19 formed on the side wall 12a of the overflow rod 12 by the elastic force of the elastic piece 22 as shown by the solid line in FIG. It is biased to a state of slightly protruding outward from the cutout groove 23, and is elastically held at that position by the stopper portion 19a. When the overflow ball 12 is filled with a ball, the detection lever 15 is pushed by the ball as shown by a chain line in FIG. 4 to rotate against the elastic force of the elastic piece 22, and the lever piece 19 Then, the actuator piece 20 of the switch 16 is pressed to turn on the switch 16. At the same time, the power supply circuit of the hitting motor 21 is opened, and the hitting of the hitting ball by the motor 21 is stopped.
[0019]
7 and 8 show the detection lever 15 provided with a rib piece 24 for restricting the bending of the elastic piece 22 in the pressing direction. By providing the rib piece 24 in this manner, even when the elastic piece 22 is pressed more strongly than necessary when the detection lever 15 is attached, the elastic piece 22 hits the rib piece 24. Accidents such as disappearance can be prevented. 9 and 10 show the elastic piece 22 provided with a knob 25. FIG. Thus, by providing the knob | pick part 25 in the elastic piece 22, the detection lever 15 can be attached while holding this knob | pick part 25, and the attachment operation | work becomes easy.
[0020]

FIGS. 11 and 12 show a protrusion 26 on the elastic piece 22 and a slot 27 corresponding to the protrusion 26 on the side wall 12a of the overflow rod 12, By causing the protrusion 26 to face the groove 27, the detection lever 15 is prevented from falling off. Further, FIG. 13 is provided with a blocking piece 28 against which the elastic piece 22 of the detection lever 15 abuts when the detection lever 15 moves in the direction in which the axis is removed from the inner side wall 12a of the overflow rod 12.
[0021]
In the case of the above-described embodiments, even when the detection lever 15 is attached at the time of assembling the pachinko machine, the mechanism plate 6 may be moved to the next process or carried without the cover plate 14 being attached. The detection lever 15 does not come off the mechanism plate 6 and falls off, so that workability is improved.
