And a dish member 17 housed inside the front decorative member 16. The plate member 17 is a ball storage unit 1 having a large front and rear width.
8 is formed on one side, and the front and rear widths are gradually reduced from the ball storage section 18 so that the ball alignment path 19 through which the balls can flow down in a single row is slightly inclined downward toward the other side. It is formed. When the plate member 17 is attached to the opening / closing panel 3, the lower end of the ball alignment path 19 communicates with the ball passage opening 20 of the opening / closing panel 3, and the ball intake flow of the ball feeder 6 via the ball passage opening 20. It is connected to the road 21.

The ball feeder 6 is a ball feed unit case.
It is attached to the back side of the opening / closing panel 3 while being housed in a box-shaped unit case 22. The unit case 22 includes a plastic main body 22a and a lid 22b attached to the lower part of the main body so as to be detachable or openable. The unit case 22 has a ball entrance 23 communicating with the ball passage opening 20 on the front side of the main body 22a. , The ball inlet 23 from the ball inlet 23
Is formed inside. In the embodiment shown in the drawings, the bottom of the ball intake channel 21 is integrally formed with the lid 22b, and the ball intake channel 21 is formed when the lid 22b is closed. Further, a flow-down direction conversion unit 24 having a curved end surface is formed at a position facing the ball inlet 23 so that the ball flowing into the ball intake flow path 21 from the ball inlet 23 can smoothly change the flow direction. A ball release shutter 25 is provided at the bottom of the inclined lower end of the intake channel 21. Then, a ball feeding member 26 is disposed so as to face the lower inclined end of the ball intake flow path 21, and the ball feeding member 2 is disposed.
6 are upper mounting the electromagnets 27 to the.

The ball feeding member 26 has a rear end pivotally mounted on the body 22a side of the unit case 22 by means of a shaft 28, and a ball restraining portion 29 at the upper end of the ball intake flow path 21 facing the inclined lower end.
A ball mounting portion 30 is formed at the lower end, and a space surrounded by the ball suppressing portion 29 and the ball mounting portion 30 and the like is used as a ball storage space 3 for one ball.
There is one. Then, the upper part of the ball feeding member 26 is sucked.
A downwardly U-shaped iron plate 32 is put on and fixed as a magnetic member.

The magnetically absorbing member may have any structure as long as it has a function of transmitting the suction operation of the electromagnet 27 to the ball feeding member 26. When the ball feed member 26 is directly driven by the magnetic force, any magnetic absorbing material that is attracted by the magnetic force may be made of iron or nickel, and its shape is not limited.

In this embodiment, the operating range restricting means for restricting the operating range of the ball feeding member 26 includes a ball feeding member 26 which swings up and down at a front end portion around a shaft 28 at a rear end. A receiving plate 33 is provided below the distal end portion of the feed member 26 to serve as a lower operating range restricting means . Also, a holding member 34 for an elongated shock absorbing member having an open bottom surface above the distal end portion of the ball feed member 26 is provided in the unit case 22. The shock absorbing member 35 made of an elastic material such as rubber is fixed in the shock absorbing member holding member 34 to form upper operating range restricting means .

Accordingly, the ball feeding member 26 always descends by its own weight and stops in the first state (FIG. 5) supported by the receiving plate 33. When the ball feeding member 26 is pulled up by the electromagnet 27 to be described later, the ball restraining portion 29 is provided. The upper end of the shock absorbing member 35
(Second state) and stops (FIG. 6), and the operating range is regulated by the receiving plate 33 and the shock absorbing member 35.

[0014] Incidentally, the receiving plate 33, a sphere in the spherical housing hollow portion 31 of the ball feeding member 26, and the rolling by the inclination of the spherical housing hollow portion 31 bottom surface, ball feed port 36 opened in the lid 22b From the ball, and is positioned at such a height that the ball restraining portion 29 abuts on the earliest ball in the ball intake channel 21 to prevent the ball from flowing down in the ball intake channel 21. . Further, the shock absorbing member 35 moves the ball restraining portion 29 of the ball feeding member 26 out of the foremost ball in the ball intake channel 21 and the foremost ball rolls into the ball storage space 31. The iron plate 32 enters the electromagnet 27
Are arranged at a height where a slight gap is formed between the iron plate 32 and the iron core 37 without contacting the iron core 37.

The above-described electromagnet 27 is provided with a coil 38 on an iron core 37 having a downward U-shape, and with the tip of the iron core 37 facing the iron plate 32 of the ball feeding member 26, the position of the ball feeding driving means is regulated. It is attached to a predetermined position in the unit case 22 by a part. The ball feed drive means position restricting portion shown in the drawing includes a downward U-shaped ridge 39 which surrounds the upper portion of the iron core 37 and regulates the height and left and right of the iron core 37.
Are formed integrally with the inner surface of the unit case 22, and a protrusion 40 that is located between the tips of the iron core 37 and regulates the left and right positions of the tip of the iron core 37 is formed integrally with the inner surface of the unit case 22. Therefore, when attaching the electromagnet 27 to the inside of the unit case 22, if a screw is inserted into the attachment hole formed in the iron core 37 and the male screw portion at the tip of the screw is screwed into the female screw portion of the unit case 22, The iron core 37 is fixed in a state where the height and the position thereof are regulated by the action of the downwardly protruding ridge 39 and the projection 40.

When playing a game in a pachinko machine provided with the ball feeder 6 having the above-described configuration, when a player throws balls into the ball storage section 18 of the ball supply tray 5, these balls are placed in the ball alignment path 19. Are introduced into the ball intake passage 21 through the ball passage opening 20 of the opening / closing panel 3 through the ball inlet 23 of the unit case 22 while flowing down. When the player does not operate the firing operation handle (not shown), the electromagnet 27 remains demagnetized, and the ball feed member 26 descends its tip and stops in the first state supported by the receiving plate 33. (FIG. 5). Therefore, the ball introduced into the ball intake flow path 21 waits in a state where the earliest ball is in contact with the ball restraining portion 29 of the ball feeding member 26 and is prevented from flowing down.

When the player operates the firing operation handle,
First, the electromagnet 27 is excited for a predetermined time by a signal from the electric control device 12. When the electromagnet 27 is excited, the iron plate 32 of the ball feeding member 26 is attracted upward by the magnetic force of the tip of the iron core 37, so that the ball feeding member 26 moves up its tip about the shaft 28 (counterclockwise in the figure). Direction). Then, the rotated ball feed member 26 is stopped by the ball restraining portion 29 at the upper end of the ball contacting the impact absorbing member 35 (second state) (FIG. 6). In this way, even if the ball feeding member 26 is rotated upward by a strong force by the driving of the electromagnet 27 and abuts against the shock absorbing member 35 to stop, the shock absorbing member 35 made of an elastic body is And the shock absorbing member 35 secures a gap between the iron plate 32 of the ball feed member 26 and the iron core 37 of the electromagnet 27 to prevent the ball feed member 26 from contacting the electromagnet 27. Because
No large vibration occurs. In addition, since the shock absorbing member 35 and the receiving plate 33 are disposed on the distal end side of the ball feeding member 26, the stop position of the ball feeding member 26 can be regulated accurately, and the wear is small.

When the ball feeding member 26 is changed to the second state,
Since the ball restraining portion 29 of the ball feeding member 26 comes off the foremost ball of the ball intake channel 21, the ball rolls and the ball feeding member 26
Into the ball storage space 31, and the next ball is the ball storage space 3.
1 is prevented from flowing down by the sphere that has entered the
Stop at the falling tip of. Since the balls stored in the ball storage space 31 are located higher than the upper opening edge of the ball supply port 36 of the lid 22b, they are held down by this upper opening edge and flow down to the firing rail 7 side. I will not do it.

When the electromagnet 27 is demagnetized after a lapse of a predetermined time, the ball feed member 26 rotates around the rear end shaft 28 in the direction of descending the tip with the weight of the ball. Ball feed member 2
When the ball 6 returns and rotates, the ball in the ball storage space 31 also descends, so that the ball comes off the foremost ball in the ball intake flow path 21. Ball contact portion 29 contacts the earliest ball. Therefore, the ball at the earliest position in the ball intake channel 21 is blocked by the ball restraining section 29 and stands by. Further, when the ball feed member 26 returns and rotates and descends its tip, the ball in the ball storage space 31 also descends and comes off the upper opening edge of the ball supply port 36. Therefore, the ball in the ball storage space 31 passes through the ball supply port 36, falls on the firing rail 7, rolls by the downward inclination of the firing rail 7, and is formed at the inclined lower end of the firing rail 7. It is supplied to a certain firing position 7 'and stops.

At this time, the rotary solenoid 9 is actuated by a signal from the electric control device 12 to rotate the firing rod 11 from the standby position toward the elastic position 7 '. Therefore, the ball supplied to the firing position 7 'is
, And jumps from the firing rail 7 through the guide rail into the game section and is provided for a game.

When the ball supplied to the firing position 7 'is fired, the rotary solenoid 9 is demagnetized and rotates back to start returning to the firing standby position.
, The electromagnet 27 is excited again, and the next ball is supplied to the firing position 7 'in the same manner as described above. In this manner, the ball feeder 6 synchronizes with the firing operation of the hitting ball launcher 4 by the signal from the electric controller 12 (the predetermined time difference is maintained in the excitation timing of the electromagnet 27 and the rotary solenoid 9). While supplying the ball repeatedly to the firing position 7 '.

When the game with the pachinko machine is to be stopped in a state where the balls remain in the ball supply tray 5, the ball removing operation unit (not shown) provided on the ball supply plate 5 is operated. When the ball moving shutter 25 of the ball taking-in channel 21 moves, these balls are discharged through the ball removing channel 41 to the lower plate in front of the pachinko machine.

In the embodiment shown in the drawings, heat dissipation holes 42 are formed in the cover 22b of the unit case 22 at positions opposite to the electromagnets 27 so that the heat generated by the electromagnets 27 can be dissipated. From the outside of the case 22.

Absorbing part held by the held shock absorbing member holding member
It is regulated by the material and maintained accurately, and the impact when the ball feed member operates is absorbed by the elastic body, so the electromagnetic
Even if the ball feeding member is driven by a strong driving force in a normal state in consideration of the fluctuation of the power supplied to the stone , the inconvenience caused by the impact can be avoided. For this reason, even if it is operated for many years, the degree of mechanical fatigue (for example, a decrease in strength due to wear or aging) is lower than that of a ball feeder in a conventional pachinko machine, and operation has been performed for a long time. Even so, it is possible to reliably feed the ball, whereby the resilience of the game ball is stabilized, and the occurrence of a so-called uneven flying phenomenon can be suppressed. further,
The magnetically absorbing member fixed to the ball feed member rotates to the electromagnet side.
Thus, when the state of maintaining the suction state is maintained,

Therefore, the magnetically absorptive member and the electromagnet do not come into contact with each other.
Not wear and respond to next operation
Ball movement to the ball launcher with improved speed and stability
Can be expected.
