By the way, among those described in the prior art, in the case where the ball storage state detecting device is provided inside the prize ball tank, the pachinko ball remains in the prize ball tank. Since the ball storage state detection device works in this state to replenish the balls, there will always be play balls in the prize ball tank, and it is necessary to increase the amount of pachinko balls held by the entire amusement store. In addition to being economically wasteful, there has been a problem in that frequent replenishment is performed and the player is annoyed.

Further, in the case where the ball storage state detecting device is provided at the bottom of the outflow gutter, the ball storage state detecting device works in a state where the pachinko ball in the prize ball tank is completely emptied to supply the ball. Therefore, if the prize balls are continuously paid out during this period, there is a problem in that the supply cannot be made in time, the ball is out of play, the game is interrupted, and the player is annoyed. Especially in recent pachinko machines, a large number of prize balls are generated in a short time when a special game state called a big hit occurs, and a large amount of prize balls are paid out. There is a possibility that it will not be in time. An object of the present invention is to provide a ball storage state detecting device in a prize ball tank in a pachinko machine which can detect a ball storage state in the prize ball tank under optimum conditions and can perform an ideal supply.

[0005]

In order to achieve the above object, the present invention provides a pachinko ball in a prize ball tank below the outlet of a prize ball tank provided at the upper part of the back surface of a game board. In a pachinko machine provided with a lead-out gutter leading to the device, a detection plate that swings by a pressing force of a pachinko ball staying in the upstream end portion is provided on a side surface portion of the upstream end of the lead-out gutter, and the detection plate. a detection switch for by connexion operated swing of the sensing plate to the outer position provided, prize balls tanks

Embodiments 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. 1 is a game board, 2 is a mechanism plate rotatably mounted on the back surface of the game board 1, and 3 is an upper part of the mechanism board 2. A fixed prize ball tank, 4 is an outlet of the prize ball tank 3 (see FIG. 3), and 5 is a discharge gutter located below the prize ball tank 3 and having its upstream end facing the outlet 4. Reference numeral 6 is a prize ball payout device arranged at the downstream end of the outlet gutter 5. Below the prize ball payout device 6, a discharge passage 7 is formed for guiding the paid prize ball to a hitting ball supply tray (not shown) in front of the pachinko machine. Further, a ball removal passage 8 is provided in the middle of the discharge passage 7, and a switching lever 10 that is rotated to a position where the discharge passage 7 is closed by the operation of a solenoid 9 is rotatably provided at the branched portion. It is provided.
As shown in FIG. 6, the prize ball payout device 6 includes a sprocket 12 facing a supply passage 11 communicating with the outlet gutter 5 and a solenoid 13 for driving the sprocket. The sprocket 12 is locked to prevent the sprocket 12 from rotating. Therefore, the pachinko balls in the prize ball tank 3 naturally flow down from the outlet 4 to the supply passage 11 via the outlet gutter 5, are received by the outer peripheral recesses of the sprocket 12, and stand by in a continuous state. Then, when the solenoid 13 is activated by the generation of the winning ball, the sprocket 12 is released from being locked by the stopper member 14 and rotated, and the pachinko ball of the supply passage 11 is paid out to the discharge passage 7 as a prize ball. .

In FIGS. 2 and 3, a side surface portion of the upstream end of the outlet gutter 5 is opened over the front surface, and a detection plate 15 is arranged so as to close the opened side surface portion.
The lower portion of the detection plate 15 is pivotally attached by a shaft 16 and the upper end thereof is located near the lower edge of the outlet 4 of the prize ball tank 3.

On the other hand, a detection switch 17 is provided outside the detection plate 15. This detection switch 17 uses a micro switch having a normally closed contact in the case of this embodiment, and is fixed to the back surface of the mechanism plate 2 so that the switch button 18 thereof is positioned in contact with the outer surface of the detection plate 15. ing.
Then, as shown in FIG. 3, when the detection plate 15 is swung outward by the pressing force of the pachinko ball staying at the upstream end portion of the outlet gutter 5, the detection plate 15 is always kept in the off state. Further, as shown in FIG. 4, the pachinko ball in the prize ball tank 3 becomes almost empty, and the pressing force of the pachinko ball staying at the upstream end portion of the outlet gutter 5 becomes small, and the spring built in the detection switch 17 ( When the detection plate 15 swings inward by a not-shown), it is turned on to send a detection signal, and the replenishing device (not shown) is actuated by this detection signal to give a prize ball tank. A predetermined number of pachinko balls are supplied to 3.

An inclined guide wall 19 is formed on the inner surface of the side wall of the prize ball tank 3 so as to cover the upper end of the detection plate 15, and the pachinko ball in the prize ball tank 3 is led out from the outlet 4. It is made to flow down to the upstream end portion of No. 5 without delay. Further, the guide wall 19 works to prevent the pachinko ball flowing down from the outlet 4 from being caught in the upper end of the detection plate 15. Further, in the above-described embodiment, the detection plate 15 is provided by opening the side surface portion at the upstream end of the outlet gutter 5, but as shown in FIG. 5, the detection plate 15 is provided at the inner position without opening the side surface portion. May be provided. in this case,
An arm 20 protruding outward from the side surface is integrally formed on the detection plate 15, and the arm 20 is positioned in contact with the switch button 18 of the detection switch 17.

Since the present invention is constructed as described above, it has the following effects. A detection plate that swings due to the pressing force of the pachinko ball that stays at the upstream end is provided on the side surface of the upstream end of the outlet gutter so that the ball storage state in the prize ball tank can be detected by the swing of the detection plate. Therefore, as in the past, it was replenished with a lot of pachinko balls remaining in the prize ball tank, or the prize ball tank became empty and the supply could not be made in time. It is possible to solve the problem, and it is possible to detect the ball storage state in the prize ball tank under the optimum condition, and the most ideal replenishment becomes possible.

Further, by pivotally supporting the lower end of the detection plate, it is possible to detect the decrease in the amount of pachinko balls staying at the upstream end portion of the outlet gutter without delay and reliably, so that the timing of replenishment is delayed. There is an advantage that it is possible to completely prevent such a situation that a ball-out condition occurs.
