The opening / closing panel 4 is provided with a ball supply tray 18 on the front side and a unit case 19 on the back side. A ball introduced from the ball supply tray 18 through the ball passage opening into the unit case 19 is projected on the rail. A ball supply mechanism for supplying one to the firing positions 12 of the 8 is built in.

The unit case 19 includes a case body 19a.
As shown in FIG. 5, a first side surface portion 19a 'on the side surface of the case body 19a covers the upper side of the firing rail 8 with the open / close panel 4 closed as shown in FIG. And a second side surface portion 19a ″ that covers the entrance upper portion of the foul ball collection gutter 9 adjacent to the firing rail 8 or the inclined lower end portion of the outer rail 13 from the side.
Is formed on the opening / closing cover 19b. The ball supply port 20 for sending out the ball toward the firing rail 8 and the ball in the ball supply plate 18 are connected to the lower plate 21.
A passage opening 22 through which the ball passes when the ball is pulled out is opened.

Then, a holder 23 is formed integrally with the opening / closing cover 19b on the front side of the opening / closing cover 19b in which the ball supply port 20 is opened, that is, on the firing rail 8 side. A sphere counting sensor 24 (corresponding to the sphere detection sensor of the present invention) is mounted so that the sphere counting sensor 24 can electrically detect a sphere passing through the sphere supply port 20.

The sphere counting sensor 24 may be of any configuration as long as it can detect a sphere and transmit a signal. In this embodiment, a downward U-shaped photo sensor having a sphere passing space 25 is used. are doing.

In this embodiment, the ball counting sensor 24 has a U-shape, so that the holder 23 is formed as an open top frame capable of storing the ball counting sensor 24, and a bottom portion extending from the lower edge of the opening of the ball supply port 20. Side surfaces 27, 27 are formed on both sides of each side surface 26, a protection surface portion 28 which also functions as a locking piece is formed on a side edge of each side surface portion 27, and a locking projection 29 is formed on the upper inside of each side surface portion 27. It becomes. Note that the width of the side surface portion 27 is set slightly larger than the thickness of the ball counting sensor 24, and the height from the bottom surface portion 26 to the locking projection 29 is set slightly larger than the vertical length of the ball counting sensor 24.

In order to mount the ball counting sensor 24 on the holder 23 having such a configuration, as shown in FIG. 5, the ball counting sensor 24 is attached to the holder 2 with the opening thereof facing downward.
3, the ball counting sensor 24 is lowered in this state, and the ball counting sensor 24 is loaded into the both side portions 27 of the holder 23 from the lower end. When the ball counting sensor 24 is sufficiently lowered, the ball counting sensor 24 fits in the storage space surrounded by the bottom surface 26, both side surfaces 27, 27 and the protection surfaces 28, 28, and the locking projections 29, 29 locked to the upper end of the sensor 24, the protective surface portions 28 covers the surface as well as engaging the surface of the firing rails 8 side of the sphere counting sensor 24.
Therefore, the ball counting sensor 24 is protected in a state where most of the ball counting sensor 24 except the upper surface portion and the ball passing space 25 are covered by the holder 23. For this reason, even if it receives a vibration or an impact, it does not come off from the holder 23, nor does it hit the launch ball or foul ball directly.

When the ball counting sensor 24 is mounted on the holder 23 in this manner, the ball supply port 20 communicates with the ball passing space 25 of the ball counting sensor 24. Therefore, when a ball passes through the ball passage opening 25 of the ball counting sensor 24 after passing through the ball supply port 20, it acts on the ball counting sensor 24 at this time, whereby the ball counting sensor 24 sends out a ball detection signal. . If the ball counting sensor 24 is mounted in a state where the ball passage space 25 is communicated with the ball supply port 20, the ball can be reliably detected. Never. Also, holder 2
The mounting work is also easy because it is only fitted into the mounting member 3.

As shown in FIGS. 6 and 7, the case body 19a to which the opening / closing cover 19b having the above-mentioned ball counting sensor 24 is attached has a ball entrance 30 communicating with the ball passage opening on the front side. Ball inlet channel 31 from ball inlet 30
Is formed inside. In the embodiment shown in the drawings, the bottom of the ball intake channel 31 is formed integrally with the open / close cover 19b, and the ball intake channel 31 is formed when the open / close cover 19b is closed. In addition, a ball release shutter is provided at the bottom of the inclined lower end of the ball intake channel 31. Then, a ball feed member 32 is disposed facing the lower end of the ball intake passage 31 and an electromagnet 33 is mounted above the ball feed member 32 as an electric drive source for ball feed.

The ball feed member 32 has its rear end axially attached to the body of the unit case 19 by means of a shaft 34, and has a ball restraining portion 35 at the upper end of the ball intake flow path 31 facing the inclined lower end and a lower end at the lower end. A ball mounting portion 36 is formed, and the ball restraining portion 35 and the ball mounting portion 36 are formed.
The empty space surrounded by the above is a ball storage empty space 37 for one ball. Then, a downward U-shaped iron plate 38 is placed over and fixed to the upper portion of the ball feed member 32. When a plunger-type solenoid or the like is used as the ball-driving electric drive source, the driving force of the solenoid may be transmitted to the ball-feeding member 32 via a link mechanism or the like.

In this embodiment, in order to regulate the operating range of the ball feed member 32, the tip of the ball feed member 32 swings up and down about the shaft 34 at the rear end.
A receiving plate 39 is provided below the tip of the ball feed member 32, and an impact absorbing member 40 made of an elastic material such as rubber is fixed above the tip of the ball feed member 32.

Therefore, the ball feed member 32 always descends by its own weight and stops in the first state (FIG. 6) supported by the receiving plate 39. When the ball feed member 32 is lifted up by the electromagnet 33 described later, the ball restraining portion 35 The upper end of the shock absorbing member 40
7 (FIG. 7), and the operating range is regulated by the receiving plate 39 and the shock absorbing member 40.

The receiving plate 39 is provided so that the ball in the ball storage space 37 of the ball feed member 32 is positioned on the bottom surface 26 of the ball storage space 37.
Of the ball, the ball can drop onto the firing rail 8 from the ball supply port 20 opened in the opening / closing cover 19b, and the ball restraining portion 35 contacts the earliest ball in the ball intake flow path 31 and It is arranged at a height that prevents the balls from flowing down in the intake channel 31.
Further, the shock absorbing member 40 is configured such that the ball restraining portion 35 of the ball feeding member 32 is disengaged from the earliest ball in the ball intake passage 31 and the earliest ball rolls into the ball storage space 37. The iron plate 38 is disposed at such a height that there is a small gap between the iron plate 38 and the iron core without the iron plate 38 coming into contact with the iron core of the electromagnet 33. Further, the electromagnet 33 is provided with a coil provided on a downwardly U-shaped iron core, with the tip of the iron core facing the iron plate 38 of the ball feed member 32.

When playing a game in the pachinko machine 1 provided with the ball supply mechanism having the above-described configuration, when a player throws balls into the ball supply tray 18, these balls are lined up while flowing down the ball alignment path. And is introduced into the ball intake passage 31 from the ball passage of the opening / closing panel 4 through the ball inlet 30 of the unit case 19. The player operates the firing operation handle 41
When no is operated, the firing switch and the touch switch are off, so that the electromagnet 33 remains demagnetized, and the ball feed member 32 descends its tip and stops in the first state supported by the receiving plate 39 (FIG. 6). ). Therefore, the ball intake channel 3
The ball introduced into 1 waits in a state where the earliest ball is in contact with the ball restraining portion 35 of the ball feeding member 32 and the flow-down is prevented.

When the player operates the firing operation handle 41, the firing switch and the touch switch that are turned on and off by the operation of the firing operation handle 41 are turned on, and a start signal is sent to the electric control device 42. Glass frame and closing panel 4 has become a closed state normally, when the gold frame switch and path <br/> Ne pulse switch closed signal is sent to the electronic control unit 42, an activation signal as described above Based on this, the electric control device 42 supplies power to the electromagnet 33 for a predetermined time to excite the electromagnet 33. When the electromagnet 33 is excited, the iron plate 38 of the ball feed member 32 is attracted upward by the magnetic force of the tip of the iron core, so that the ball feed member 32 moves up its tip about the shaft 34 (counterclockwise in FIG. 6). Direction). Then, the rotated ball feed member 32 is attached to the ball restraining portion 3 at the upper end.
5 comes into contact with the shock absorbing member 40 (second state) and stops (FIG. 7).

When the ball feed member 32 is changed to the second state,
Since the ball restraining portion 35 of the ball feed member 32 comes off the foremost ball of the ball intake channel 31, the ball rolls and the ball feed member 32
Into the ball storage space 37, and the next ball is in the ball storage space 3
7 is prevented from flowing down by the sphere that has entered the sphere 7, and the sphere intake channel 31
Stop at the falling tip of. The ball stored in the ball storage space 37 is located higher than the upper opening edge of the ball supply port 20 of the opening / closing cover 19b. It does not flow down.

When the electromagnet 33 is demagnetized after a lapse of a predetermined time, the ball feed member 32 rotates around the rear end shaft 34 in the direction of descending the tip with the weight of the ball. Ball feed member 3
When the ball 2 returns and rotates, the ball in the ball storage space 37 also descends, so that the ball comes off the foremost ball of the ball intake channel 31. Ball contact portion 35 contacts the earliest ball. Therefore, the ball at the earliest position in the ball intake channel 31 is blocked by the ball restraining section 35 and is on standby. When the ball feed member 32 returns and rotates and descends its tip, the ball in the ball storage space 37 also descends and comes off the upper opening edge of the ball supply port 20. Therefore, the ball in the ball storage space 37 rolls due to the inclination of the bottom of the ball storage space 37 and is sent out of the unit case 19 from the ball supply port 20, and when the ball passes through the ball supply port 20. The ball counting sensor 24 that has detected the ball sends a ball detection signal to the electric control device 42. And the ball counting sensor 24
The ball that has acted on falls on the launch rail 8
Is rolled by the downward inclination of and supplied to the firing position 12,
Here, the operation is temporarily stopped.

When a ball is supplied to the firing position 12, the rotary solenoid of the hit ball firing device 10 is operated by a signal from the electric control device 42 to rotate the firing rod 11 from the standby position to the firing position 12. Move. Therefore, the ball supplied to the firing position 12 is hit by the hitting portion 11 ′ of the firing rod 11, jumps into the game area 15 from the firing rail 8 via the outer rail 13, and is used for a game. .

When the ball supplied to the firing position 12 is fired, the rotary solenoid is demagnetized and turns back to start returning to the firing standby position. At this time, the electromagnet 33 is again turned on by a signal from the electric control device 42. Since it is excited, the next sphere is supplied to the firing position 12 as before. In this manner, the ball supply mechanism is synchronized with the firing operation of the launching device 10 by a signal from the electric control device 42 (while maintaining a predetermined time difference in the excitation timing of the electromagnet 33 and the rotary solenoid), One ball is repeatedly supplied to the firing position 12. The ball counting sensor 24 exits the ball supply port 20 when the ball supplied to the firing position 12 through the ball supply port 20 by the operation of the ball supply mechanism enters the ball passage empty space 25. At this time, the ball detection signal is sent to the electric control device 42.

If the hit ball is returned to the firing rail 8 as a foul ball, the ball counting sensor 24 does not detect the ball on the firing rail 8 and detects the foul ball to detect the ball. The detection signal is not sent to the electric control device 42. Also, the ball counting sensor 24 is
Since the ball is mounted in a protected state by being surrounded by the inside, the hit ball or foul ball that hits the ball counting sensor 24 does not substantially occur. Therefore, it is possible to reduce the possibility that the collision of the ball causes the failure of the ball counting sensor 24, and it is possible to prevent the hit ball that has been shot from coming into contact with the ball counting sensor 24 and flying unevenly.

The ball counting sensor 24 of the present invention
May be any type of detector as long as it has a function of detecting a sphere supplied from the sphere supply port 20 and transmitting a signal. Further, the holder 23 holding the ball counting sensor 24 may have any configuration as long as the holder 23 can hold the ball counting sensor 24 facing the ball supply port 20. For example, a configuration may be adopted in which a plurality of claws project from the opening / closing cover 19b, and the ball counting sensor 24 is held outside the ball supply port 20 by these claws.

Even if a return ball is generated by a foul ball, the return ball is not detected again, and the number of shot balls can be counted accurately. In addition, since the ball detection sensor is arranged on the opening and closing panel side, the launch ball and the return ball do not directly hit the ball detection sensor, so it is possible to prevent troubles such as breakdown due to collision of the ball before launching The occurrence of uneven flying due to the contact of the ball with the ball detection sensor can also be prevented, and the launch of the ball is stabilized. In addition, since the ball detection sensor is disposed on the ball supply port side of the open / close panel, high mounting accuracy is not required , and the ball detection sensor can be mounted on the open / close panel together with the unit case having the ball supply mechanism. And wiring processing can be performed efficiently. Further, the maintenance panel and the cleaning operation can be easily performed by opening the open / close panel.
