The actuator and the actuator for the switch for lamp display can be pressed to turn them on, and it is possible to detect the out-of-ball state of either the first guide trough or the second guide trough with two switches. Becomes

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a rear view of a pachinko machine to which the present invention is applied, wherein 1 is a game board mounting frame, 2 is a game board, and 3 is a mechanism plate rotatably mounted on the back surface of the game board 2. The mechanism plate 3 is
It has a plate-like portion 3a that forms a prize space apart from the back surface of the game board 2 at regular intervals, and a first prize-ball collecting portion 4 and a second prize-ball collecting portion 5 are provided below the plate-like portion 3a. Is formed.
The prize ball tank 6 is fixed to the upper portion of the back surface of the plate-shaped portion 3a. Below the prize ball tank 6, the prize balls are aligned and
First guide trough 8 having two ball passages 8a, 8a for guiding to the prize ball discharging mechanism 7 and second guide having one ball passage 10a for guiding to the second prize ball discharging mechanism 9. A gutter 10 is formed. Below the first prize ball discharging mechanism 7 and the second prize ball discharging mechanism 9, there is formed a prize ball discharging trough 11 for guiding the discharged prize balls to the hitting ball supply tray on the front surface of the pachinko machine.
Further, the mechanism plate 3 includes a first winning ball discharging processing mechanism 12 for discharging the winning balls collected in the first winning ball collecting unit 4 one by one to the outside of the machine, and a second winning ball collecting unit 5. Second prize ball discharge processing mechanism 13 for discharging collected prize balls one by one out of the machine
Is provided. Then, by the operation of the first winning ball discharge processing mechanism 12, a predetermined number of, for example, from the first prize ball discharging mechanism 7
The 13 prize balls are discharged to the prize ball discharge gutter 11 and a predetermined number, for example, 7 prize balls are discharged from the second prize ball discharge mechanism 9 by the operation of the second prize ball discharge processing mechanism 13. Is released to.

The first guide gutter 8 corresponding to the outlet 14 of the prize ball tank 6
A first ball detecting member 15 is provided on the bottom of the second guiding gutter 10 and a second ball detecting member 16 is provided on the bottom of the second guiding trough 10.
As shown in FIGS. 2 and 3, the first and second sphere detection members 15 and 16 are rotatably supported on the mechanism plate 3 by a shaft 17 on the right side thereof. As shown in FIG. 7, a first switch lever 151 and a mounting piece 152 are formed on the lower surface on the left side of the first ball detecting member 15. The first switch lever 151 is provided with a horizontal receiving piece 153 at the lower end and is formed in an L shape when viewed from the side. In addition, the connection lever 1 is attached to the mounting piece 152.
The upper end of 8 is pivotally attached, and the lower end of the connecting lever 18 is pivotally connected to one end of a link 20, the middle of which is pivotally supported by a shaft 19. Further, the other end of the link 20 is linked to a ball stopping mechanism 22 via a vertical rod 21. The ball stopping mechanism 22 rotates the links 23 and 24 with the rise of the vertical rod 21 to prevent the hit ball from flowing into an automatic ball feeder (not shown).

When the prize balls are stored in the prize ball tank 6, the first ball detection member 15 receives the weight of the ball and is placed at the position shown by the solid line in FIG. When the prize balls decrease and the ball passages 8a, 8a of the first guide gutter 8 become empty, the weight 25 provided on the link 20 causes the weight to rotate upward as shown by the chain line in FIG. ing.

On the lower surface located on the left side of the second ball detection member 16, there is an eighth
A second switch lever 161 is formed as shown. The second switch lever 161 has an inverted T-shape when viewed from the side by providing projecting pieces 162 projecting on both sides so as to be flush with the upper surface of the receiving piece 153 of the first switch lever 151 at the lower end. Is formed. The second ball detecting member 16 is placed at the position shown by the solid line in FIG. 5 when the prize balls are stored in the prize ball tank 6.
When the ball in the inside is reduced and the ball passage 10a of the second guide gutter 10 becomes empty, the coil spring 26 wound around the shaft 17 causes the coil spring 26 to rotate upward as shown by the chain line in FIG. It has become.

A micro switch 27 for supplying a command and a micro switch 28 for indicating a lamp are fixed to the back surface of the mechanism plate 3 located below the first ball detecting member 15 and the second ball detecting member 16, The respective actuators 271 and 281 are brought into contact with the receiving piece 153 of the first switch lever 151 and the projecting piece 162 of the second switch lever 161. The micro switch 27 is connected to a hall computer for a replenishment command signal, and the micro switch 28 is connected to a lamp 29 of a ball out display portion provided on the surface of the game board 2. Then, when the first ball detecting member 15 and the second ball detecting member 16 are placed at the positions indicated by the solid lines in FIGS. 4 and 5, they are urged downward by a built-in spring member to be turned off. It is kept.

The present invention is configured as described above, and when the prize balls in the prize ball tank 6 decrease and the ball flow paths 8a, 8a of the first guide trough 8 become empty, as described above, Detection member 15 is linked
By the action of the weight 25 provided on the 20, it independently rotates irrespective of the second ball detecting member 16 as shown by the chain line in FIG. 4, and the receiving piece 153 of the first switch lever 151 allows both microswitches to move. 27, 28
The actuators 271 and 281 of No. 2 are pushed to turn on both the micro switches 27 and 28. On the other hand, when the ball flow path 10a of the second guide gutter 10 becomes an empty squad, the second ball detection member 1
6 is rotated upward by the bias of the coil spring 26 independently of the first ball detection member 15 as shown by the chain line in FIG. The actuators 271 and 281 of the switches 27 and 28 are pushed to turn on both the micro switches 27 and 28.

[Effect of device]

As described above, according to the present invention, the first guide trough that guides the prize ball to the first prize ball discharging mechanism and the second prize ball that guides the prize ball to the second prize ball discharging mechanism by the two micro switches. Since the out-of-ball condition of the guiding gutter can be detected easily and accurately, it is not necessary to use many micro switches as in the conventional case, and its economical effect is extremely great. Further, the wiring work can be simplified and the work efficiency can be remarkably improved.
