An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a partial cross section of a pachinko machine. The pachinko machine is a so-called card type pachinko machine, and a game is performed by inserting a card (not shown) storing a specific number of lending balls (the number of remaining balls) from an insertion slot 31 of a card reader 30 provided at the lower left. Can be started, the number of shots is subtracted, the number of foul balls and the number of prize balls are added, and the current number of remaining balls is displayed on the display 32.
When the end button 33 is pressed, the number of remaining balls is written on the card via the card reader 30 and then returned to the card slot 31. That is, as in the past, the prize balls are not discharged to the saucer, and a certain number of game balls are circulated and used,
This is a pachinko machine that calculates the number of losses.

Reference numeral 1 denotes a front frame of the pachinko machine, on which a metal frame 2 is fixed. An openable and closable glass door frame 4 is attached to the metal frame 2. On the back surface of the front frame 1, a game board 9 having various winning ports is attached, and ordinary winning ports 10 to 14 and specific winning ports 15 are appropriately arranged. The big winning port 19 arranged below the symbol display device 18 is kept open for a certain period of time to receive a game ball when the symbol winning device 19 has a large winning. Specifically, at the time of a big prize, the big prize opening 19 is kept open until a predetermined time (for example, 30 seconds) elapses, or until a predetermined number (for example, 10) of prize balls are generated before that. It is set to maintain the open state. Further, a V winning opening 20 is provided inside the special winning opening 19 so that the special winning opening 19 can be opened again. At the lower part of the V winning opening 20, there is provided an out opening 21 for collecting game balls that have not won, and it is guided to a ball feeding device 40 shown in FIG. Reference numeral 35 denotes a firing rod, which hits a game ball at a predetermined interval via a motor by operating a handle 37, and fires the game ball 9 between the inner and outer rails 36a and 36b.

FIG. 2 is a front sectional view of the ball feeder 40, and FIG.
FIG. 3 is a sectional view taken along line A-A in FIG. 2. As shown in FIG. 4, the firing tray 41 is formed to be inclined downward in the direction of the firing rod 35 with a pair of side walls 47, and a winning ball entrance 43, a foul ball and a game ball 45 from the out port 21 are provided at the left end. An outgoing ball inlet 44 is provided, and the opposite end is an open port 71. The shape of the opening 71 is a square of 11.5 mm, and the dimension and shape allow the game balls 45 to be discharged most smoothly without being affected by the subsequent game balls 45. The winning ball entrance 43 is provided with a winning ball detector 80 (proximity switch or the like) for detecting the number of winning balls, and the foul ball number is detected by a foul ball detector (proximity switch or the like) 82. When all of the game balls 45 to be circulated are lined up on the firing tray 41, a final ball detector 81 such as a proximity switch is provided at a position where the game ball is located at the rearmost position. An outlet 46 for discharging the game ball 45 to a firing portion 58 facing the firing rod 35 is formed in a side wall 47 at a lower end portion of the firing tray 41, and a swinging piece 48 for opening and closing the outlet 46 swings around a shaft 48a. It is supported as much as possible. In addition, the swinging piece 48 has a mountain-shaped side view as shown in FIGS. 3 and 4 and a downwardly inclined portion 48b which is directed in the opposite direction from the outlet 46 side so as to easily discharge the game ball 45 from the outlet 46. The limit switch 49 is disposed at a position where the detection end 49a is placed on the swinging piece 48.
9 is counted by the ON and OFF signals. On the other hand, the rocking piece 4
An L-shaped operation piece 50 that can move up and down around a shaft 50a is provided at a position facing 8 and moves up and down by raising and lowering a rod 51a of a solenoid 51 at the timing with the firing rod 35. In order to make it easier for the game balls 45 to be discharged from the exit 46, the top 70 of the operation piece 50 is also moved from the exit 46 side as shown in FIG. An upward slope is formed in the opposite direction. Needless to say, these inclined portions may be formed on only one of them. On the right side of the top 70 of the operation piece 50, a U-shaped receiving piece 52 for receiving the game ball 45 in the firing tray 41 is provided.
A discharge port 53 is provided on the side wall opposite to the outlet 46 side of the firing tray 41 (FIGS. 6 and 7 (a cross-sectional view taken along BB in FIG. 6)). The end of the receiving piece 52 is a game ball 4
7 and 8 (C to C in FIG. 6) so that
As shown in FIG.
a and 52b are formed. A stop plate 55 that opens and closes the entrance of the receiving piece 52 is a U-shaped rotatable around a shaft 55a, and is rotated through an R-shaped claw 57 that rotates integrally with the operation rod 56. It is configured to be possible. The nail 57
Is unlocked, the stop plate 55 is formed to have a weight balance capable of rotating counterclockwise about the shaft 55a.

Next, the operation of the above configuration will be described with reference to FIGS. Gaming balls 45a entering the firing tray 41 from the winning ball entrance 43 and the out ball entrance 44
Is led out from the opening 71 at the end of the tray 41 onto the top 70 of the operation piece 50, and is stopped by the stop plate 55 (FIG. 2,
(Fig. 4). When the operation piece 50 is raised via the solenoid 51, the swinging piece 48 is raised in a tightly attached state using the game ball 45a as a medium, and the game ball 45a is at a position where it can be discharged from the outlet 46 (FIG. 4, the position of the operation piece 50A and the rocking piece 48A shown in the broken line in FIG. 5), and the inclined portion 48b of the rocking piece 48
And it is discharged to the firing unit 58 by the inclined portion provided on the top 70 of the operation piece 50 (game ball 45b). Thereafter, the game ball 45 b is fired on the game board 9 via the firing rod 35. On the other hand, the rise of the rocking piece 48 causes the limit switch 49 to be in a conductive (ON) state via the detection end 49a, and the firing number of the game ball can be determined by counting the state with a counter (not shown). At the stage where the above-mentioned process is completed, the operation reverse to the above-mentioned process is performed to return to the state shown in FIG. 2, and the above operation is sequentially repeated to count the number of shot balls. The input of the counting device is a limit switch 49.
However, any device may be used as long as an ON / OFF signal is generated in accordance with the swing of the swinging piece 48 by using a photoelectric tube or by attaching a metal to the swinging piece 48 and using a proximity switch or the like. As described above, since the counting of the present invention is obtained through the swinging piece 48, that is, the input of the counting device (not shown) through the game balls 45, the malfunction of the counting of the game balls can be reduced. The counting device (not shown) subtracts the number of inputs of the limit switch 49 from the number of remaining balls, adds the signal input from the foul ball detector 82, and calculates the number of winning balls detected by the winning ball detector 80. Addition of the number of prize balls corresponding to
The number of remaining balls is displayed on the display 32 and notified to the player. Also, when the end button 33 is pressed, the last ball detector is activated after a certain period of time in order to check whether or not the game ball fired last does not catch the obstacle nail or the like and wins. Make sure that 81 is ON, and
After the number of remaining balls is written on the card via, the card is returned to the card slot 31.

Next, referring to FIG. 6, FIG. 7 (sectional view taken along the line BB of FIG. 6), and FIG. 8 (sectional view taken along the line C-C of FIG. 6), the game ball 45c in the firing tray 41 is discharged. The following describes the effect of the operation. When the operation rod 56 is rotated counterclockwise, the lock with the claw 57 is released, and the stop plate 55 rotates counterclockwise with weight balance (FIG. 6). Therefore, game ball 45
c sequentially passes through the top part 70 of the operation piece 50 and
, The game ball 45d is discharged from the discharge port 53 through the action of the inclined portions 52a and 52b. When all the game balls 45 have been discharged, the operation rod 56 is rotated clockwise to return to the original state (FIG. 2). Thus, the stop plate 5
By simply rotating 5, the game balls in the firing tray 41 can be easily discharged.
