It is delivered to the delivery passage 44. At this time, since the blocking member 48 is in the open state, the ball 3 is sent out from the delivery path 44 to the waiting path 9, and the ball 3 can be hit again by the ball hitting handle 8. On the other hand, in the control system, by subtracting the number of detections in the number storage section 64, each display storage section 65 of the second storage section 63 changes from the stored state before the retry switch 24 was turned on to the state of the retry switch 2 that was turned on.
4. The pattern of the mahjong tiles excluding the pattern of the corresponding mahjong tile is memorized in a specific order from the left end, and when the replay switch 24 is turned on in the display section 23, the pattern of the mahjong tile excluding the pattern of the mahjong tile corresponding to the pattern of the mahjong tile is stored at the left end. are displayed variably in a specific order. Then, when the ball 3 is hit again, the ball 3 passes through the ball receiver 7 configured as described above and is held in the ball holding section 25, and the display section 23 shows the ball receiver 7 through which the ball 3 has passed. The pattern of the mahjong tiles to be played is displayed in the same way as above.

After the game ends, press the payment switch 51 etc.
The game end switch 56 is turned on, and the second solenoid 42 is operated to cause the ball dispensing plate 27 to swing downward as shown by the chain line, and the ball stopper 31 to rotate downward as indicated by the chain line, thereby opening the dispensing port 26. , all the balls 3 in the ball storage section 25 fall in the direction of arrow a and are dropped into the payout passage 44. At this time, the blocking member 48 closes the payout passage 4 by turning on the game end switch 56.
4 and the waiting path 9 are in a state of being cut off,
The ball 3 is not sent to the waiting path 9 but is sent to the payout path 44.
It can be stopped inside.

According to the present invention, at least a certain number of display units are provided for variably displaying the pattern of the mahjong tiles, so the mahjong tile corresponding to the ball receiver where the ball fell can be displayed using the minimum number of display units. All the patterns can be displayed, so the patterns of mahjong tiles can be displayed compactly and easily.

In addition, a plurality of ball detection switches for detecting balls passing through the ball receiver are provided for each ball receiver, and each detection operation of each ball detection switch is memorized and the mahjong corresponding to that ball detection switch is stored. Since a control device is provided that sequentially displays the pattern of the tiles on the arbitrary display section, the number of ball detection switches for detecting balls that have fallen into the ball receivers need only correspond to the number of ball receivers; The number of can be very small. Moreover, a plurality of replay switches are provided corresponding to each display section, and when an arbitrary replay switch is operated, the control device erases the mahjong tile pattern displayed on the corresponding display section before the operation from the display section. Therefore, the number of re-hitting switches only needs to be as many as the number of pitches corresponding to the display section, and the number of re-hitting switches can be kept as small as possible. Further, a ball holding section is provided to collect all the balls that have fallen into each ball receiving section by passing through the ball receiving section, and when an arbitrary re-hitting switch is operated, one ball is delivered from the ball holding section to the waiting path. Since a dispensing mechanism is provided, each ball receiver can have a very simple structure that simply allows the fallen balls to pass through, and one ball dispensing mechanism for dispensing the balls is provided for each ball holding section. It'll be fine. Therefore, the entire device can be significantly simplified and downsized, and its practical effects are significant.
