and a solenoid 233, and when the solenoid 233 is energized, the plunger 234 protruding downward as shown by the chain line in FIG. Individual firing position 1
21.

On the other hand, inside the decorative panel section 5, there is a card reader 45 that can read recorded information on a magnetic card inserted into the card insertion slot 7, and a storage device that stores data on the number of balls held and the like recorded on the magnetic card. , winning ball detection sensor 20
A computer 44 is provided, which includes a calculation device, etc., which adds the signal from the foul ball detection sensor 43 as a (+) input, and adds the signal from the launched ball detection sensor 127 as a (-) input to perform addition/subtraction calculations.

Next, the operation of a pachinko machine will be explained. When a player inserts a magnetic card with a predetermined number of balls recorded into the card insertion slot 7, the card is read into the card reader 45, and the data such as the number of balls 8 recorded on the card is checked. . The data on the number of balls held is sent to the storage device of the computer 44 and stored therein, and is also sent to the digital display device 8 to be displayed. Further, the game stopping state of the firing device 12 and the game ball supply device 23 is released to enable firing of game balls, and the motor 35 for the return machine is rotated.

Therefore, when the player rotates the rotary handle 6, the switch 28 is turned on and the motor 123 for driving the ball is driven, and the solenoid 233 is energized. The lined up game balls are detected one by one by a firing ball detection sensor 127 and supplied to a firing position 121. Then, the game ball supplied to the firing position 121 is driven by the ball hitting rod 1 as the motor 123 is driven.
By the repeated rotation of 22, it is emitted to the game section ILa of the game board 11. The ejection signal from the ejected ball detection sensor 127 is sent as a (-) signal to the arithmetic unit of the computer 44, where 1 is subtracted and stored from the number of memories in the storage device, and 1 is subtracted from the digital display N8. The numbers will be displayed.

On the other hand, the game balls fired into the game section 11a are placed in the winning ball socket 1.
4, when winning a prize, the winning ball is guided to the winning ball collecting path 17 of the winning ball collecting section 16 on the back side of the game board 11, and passes through the winning ball detecting sensor 20 while passing through the out ball collecting path 1.
It will be gathered at 8. In addition, out balls are collected from outs 1 to 15 in the out ball collecting path 18 of the winning ball collecting section 16, and are introduced together with the winning balls from the exit 16c through the introducing path 39 to the lifting path 38 of the return machine 21. .

The signal from the winning ball detection sensor 20 is a number converted into the number of prize balls for one winning ball, for example (+1
3) sent as a signal to the arithmetic unit of the computer 44;
13 is added for each winning ball to the number stored in the storage device, and the added number is displayed on the digital display device 8. In addition, if the rebound force of the game ball fired from the firing position 121 is weak and the game ball misses firing and is received by the foul ball outlet 29, the game ball is guided to the guide path 30 on the back side of the game board 11 as a foul ball, and becomes a foul ball. While being detected by the ball detection sensor 43, the balls are collected in the out ball collecting path l8 of the winning ball collecting section 16 and introduced into the transport path 38 of the return machine 21 in the same way as winning balls and out balls. The signal from the foul ball detection sensor 43 is sent as a (+) signal to the arithmetic unit of the computer 44, where l is added to the number of memories in the storage device and stored, and 1 is added to the digital display device 8. The number is displayed. For this reason, although the foul ball is subtracted by 1 from the stored number by the signal from the shot ball detection sensor 127, it is added by 1 by the signal from the foul ball detection sensor 43, so there is no substantial subtraction.

The game balls thus fired into the gaming section 11a are either winning balls, out balls, or foul balls, and are all collected in the winning ball collecting section 16 and introduced into the transport path 38 of the return machine 21. The game balls introduced into the transport path 38 are
As the helical rotating body 32 rotates, it rises along the inner surface of the guide plate 33 while being engaged and held by the groove 31 on its circumferential surface and the guide plate 33. At this time, since the ball polishing cloth 37 is formed by pasting an abrasive cloth on the inner surface of the guide plate 33, the game balls are brought into frictional contact with the polishing surface 37, and the dirt on the surface is removed and thoroughly cleaned. The balls rise one after another while being polished, are pumped from the upper outlet to the outlet passage 40, and are further led to the spiral tank rail 22 for circulation use.

During the game, if the number of balls held in the storage device becomes zero or the settlement button 10 is pressed, a stop signal is sent, making the game impossible, and the number of balls held on the magnetic card is reset by pressing the settlement button 10. If the card has been written, the card is ejected from the card insertion slot 7 and returned to the player.

Therefore, the characteristic part of the present invention is that among the displays 8a to 8d of the digital display device 8, the displays 8c and 8d for displaying one digit and ten digit are made smaller, and the other digits for hundreds and thousands are displayed. The structure is such that the displays 8a and 8b are enlarged. The displays 88 to 8d used here employ so-called seven segment light emitting display devices, and are controlled by the computer 44.

It is considered that the intended purpose can be achieved even if the display devices 8c and 8d are configured such that only the display device 8d that displays one digit is made smaller.

[Effects of the Invention] As described above, according to the present invention, the one or ten digits, which fluctuate rapidly, are replaced by a small display, which reduces the irritation to the eyes caused by flickering caused by the fluctuations, and the display can last for a long time. This has the effect of preventing eye fatigue even when playing pachinko.
