Abstract

PURPOSE:To surely feed game balls one by one and easily discharge a prescribed number of game balls by alternately protruding and recessing a movable member having a stop part on the upper end and a ball receiving part in the lower end of a rotating member engaged with the movable member through an engaging part from and into a guide passage. CONSTITUTION:A safe ball Y fallen into a prize hole of a pachinko (Japanese pinball game) machine is guided to the inlet port 10a of a guide passage 10 through a matching gutter 53, and temporarily stayed in the stop part 21 of a movable member 20. When the safe ball Y is detected by a detector 15, the stop part 21 is retreated from the guide passage 10 since an electromagnet 16 is excited to attract the movable member 20 to a core 16a. Since a ball receiving part 28 is also protruded into the guide passage 10 while the locking part 27 of movable member 20 is engaged with the movable member 20 and rotated counterclockwise, the safe ball Y is received by the ball receiving part 28. Further, when the electromagnet 16 is demagnetized, the movable member 20 is rotated clockwise by the energizing force of a coil spring 19, and the save ball Y is thus fallen and discharged from the ball receiving part 26 to a discharge gutter 55.

Reference numeral 15 in FIG. 2 is a detector for detecting a safe sphere, and a non-contact type proximity switch or the like is used, and the detector is installed and fixed by inserting it into the void formed at the entrance 10a of the guideway 10. Has been done. When the detector 15 detects the safe sphere guided to the guide path 10,
Based on this detection signal, the electromagnet 16 is operated, and the prize ball dispensing device 62 is operated to dispense a predetermined number of prize balls.

The operating tool is for operating the movable member 20 in and out by the electromagnet 16 and the elastic body 19.
6 is surrounded by a frame body 17, and the frame body 17
It is suspended by fixing a bracket 18 attached to the to the locking piece 2a hanging from the top plate 2 of the case body 1 with a screw 3. Then, the electromagnet 16 is excited based on a signal from the detector 15 to attract the movable member 20 by the core 16a, and then demagnetized to move the movable member 20.
To release. A coil spring or the like is used as the elastic body 19. One end of the coil spring 19 is fixed to the frame body 17 and the other end is connected to the lower end of the movable member 20, and the stop portion 21 of the movable member 20 is rotated clockwise. It is designed to bias in the direction. The movable member 20 is made of a magnetizable material such as iron to have an L-shaped cross section, and an intermediate portion thereof is axially attached by penetrating through a support hole 17a formed in the frame 17 with play. It tilts back and forth around the support hole 17a. Therefore, when the electromagnet 16 is in the demagnetized state, the stop portion 21 on the front end side projects and moves into the guide path 10 from the through hole 11 by the urging force of the coil spring 19, while it is attracted to the core 16a when the electromagnet 16 is in the excited state. Exit from guideway 10 and move. A support plate 20b is formed on the movable member 20 so as to project from the support hole 17a. Further, the knob 23 on the lowermost end side of the movable member 20 extends through the long hole 4a formed in the bottom plate 4 of the case body 1, and the case body is manually operated by operating the knob 23. The movable member 20 can be tilted from the outside of 1. The rotating member 25 is engaged with the movable member 20 to be rotated, and its rotating shaft 26 is rotatable by inserting it into a bearing (not shown) attached to a side plate of the case body 1. Is pivotally supported. Then, as shown in the perspective view of the main part of FIG. 3, the locking portion 27 on the upper end side of the rotating member 25 extends along the back surface of the movable member 20 and is positioned so as to be engageable with the movable member 20. .
Here, the locking portion 27 does not necessarily have to come into contact with the movable member 20 to be coordinated, and it is sufficient that the engaging portion 27 is coordinated with the moving path of the movable member 20 and can be engaged when the movable member 20 moves.
On the other hand, the ball receiving portion 28 on the lower end side of the rotating member 25 has the locking portion 2
7 extends into the guide path in the same direction as that of the rotating member 25.
When it rotates counterclockwise about its rotary shaft 26, it projects from the through hole 12 into the guide passage 10, and when it rotates clockwise, it retreats. still,
In order to discharge the safe balls one by one, the ball receiving portion 28 has a distance between the ball receiving portion 28 and the stop portion 21 which is substantially equal to that of the safe ball 1.
It is located so as to have an individual piece.

Next, the operation of the game ball discharging device C having the above structure will be described with reference to the drawings. 4 to 6 show one safe sphere.
It is a figure showing a series of operation states which discharge one by one. First,
In a state where the safe ball is not yet guided to the guide path 10 of the game ball discharging device C, the stop portion 21 of the movable member 20 is biased by the coil spring 19 and protrudes from the through hole 11 into the guide path 10. There is. In this state, the safe ball Y moves to the rectifying gutter 53.
When it is guided to the entrance 10a of the guide path 10 via the route, it is temporarily stopped at the stop portion 21 of the movable member 20 (FIG. 4). When the detector 15 detects the safe sphere Y, the electromagnet 16 is excited, so that the movable member 20 is tilted by being attracted to the core 16a of the electromagnet 16 as shown in FIG. The stop 21 is moved out of the guideway 10. At the same time, the rotating member 25 has its locking portion 27.
Is rotated in the counterclockwise direction by being engaged with and pushed by the movable member 20, and accordingly, the ball receiving portion 28 causes the ball receiving portion 28 to move.
Move inward. As a result, the stop 2 of the movable member 20
By the retreat operation of No. 1, the safe ball Y retained at the stop portion 21 falls from here and is received by the ball receiving portion 28 protruding into the guide path 10.

Subsequently, the electromagnet 16 is demagnetized, and the movable member 20 moves the core 16 of the electromagnet 16 as shown in FIG.
It is released from a and is pressed by the biasing force of the coil spring 19 and the clockwise force of the locking portion 27 due to the own weight of the game ball, and tilts to move the stop portion 21 from the through hole 11 to the guide path 1
At the same time, the ball receiving portion 28 is urged by the own weight of the safe ball Y received here and is rotated clockwise to retreat from the inside of the guide path 10. As a result, the safe ball Y of the ball receiving portion 28 is dropped and discharged to the discharge gutter 55 side,
Since the stopping part 21 stops the next ball waiting on the upstream side of one safe ball of the ball receiving part 28 to prevent the ball from falling, the safe balls can be discharged one by one. After that, each time the safe ball is guided, it is discharged in the same manner as above. Therefore, as described above, the game ball discharging device C according to the present invention includes the movable member 2
The stop portion 21 of 0 and the ball receiving portion 28 of the rotating member 25 are alternately moved in and out of the guide path 10, so that the safe ball falling from the stop portion 21 is received by the ball receiving portion 28 and then the ball receiving portion 28 is received. Since the safe ball is ejected by retreating the portion 28 and the safe ball on the upstream side is prevented from falling by ejecting the safe balls, the safe balls can be easily ejected one by one. Also,
When the safe ball is discharged, the ball receiving portion 28 is easily rotated by being urged by the weight of the safe ball. Therefore, it is not necessary to attach a weight to the rotating member 25. Therefore, the movable member 20 is operated. The attraction force of the electromagnet 16 can be reduced.

(Second Embodiment) FIG. 7 showing the present embodiment is a sectional view of a game ball discharging device C. The same parts as those in the first embodiment are designated by the same reference numerals, and different parts will be described. To do. Unlike the first embodiment, this game ball discharging device C is configured to discharge a plurality of safe balls (game balls), and the game ball discharging device C has a long guide path 10. While being formed, the distance between the stop portion 21 and the ball receiving portion 28 is set according to the number of discharged pieces (for example, two pieces). Therefore, one safe ball and two safe balls are discharged in a mixed manner. The operation tool of the movable member 20 uses an electromagnetic solenoid 30 and is connected to a reciprocating rod 30a and a joining member 20a attached to the movable member 20. In addition, in the discharge gutter 55,
A detector 56 for detecting the falling safe sphere is installed.

The game ball discharging device C having the above-described structure performs substantially the same operation as in the first embodiment, and when the detector 15 detects the safe ball Y, the electromagnetic solenoid 30 is excited to move the rod 30a back. , The stop 21 of the movable member 20 is moved out of the guide path 10, and one or two safe balls Y are received by the ball receiving portion 28 projected into the guide path 10 (the same state as in FIG. 5). ). Subsequently, the electromagnetic solenoid 30 is demagnetized, is biased by the own weight of the safe ball Y, rotates clockwise, and moves out of the guide path 10 to move the safe ball Y of the ball receiving portion 28 into the discharge gutter. The safe balls of the ball receiving portion 28 are stopped by the stop portion 21 while being dropped and discharged to 55, so that one or two safe balls can be discharged (the same state as in FIG. 6). Therefore, the detector 5 installed in the discharge gutter 55
The number of safe balls falling at 6 is counted, it is discriminated whether it is one or two, and the prize ball dispensing device 62 is operated to dispense a predetermined number of prize balls. In this way, the game ball discharging device C can be configured to be capable of discharging a plurality of balls instead of one by one, and can discharge more quickly. Further, as in the present embodiment, since the number of safe falling balls is determined by the detector 56 installed in the discharge gutter 55, the operation of the operation tool (electromagnetic solenoid 30) is excited at a predetermined interval without a signal from the detector 15. It is also possible to configure to repeat demagnetization. Further, as shown in FIG. 8, the detector 56 of the discharge gutter 55 is omitted, and a first detector 15a (corresponding to the detector 15 of FIG. 7) is provided at the inlet 10a of the guide path 10, and The second detector 1 is located above the position of the first detector 15a by one safe sphere.
5b are installed, and when the detector 15a detects the safe sphere Y, the electromagnetic solenoid 30 is operated to detect the detector 15a.
When a and detector 15b are both "ON", two detectors, detector 1
When 5a is "ON" and detector 15b is "OFF" 1
It may be configured such that it is determined that the individual pieces are discharged.
The detector of each of the above embodiments may be of a proximity switch type, a limit switch type, a photoelectric tube type, or the like. Further, the game ball discharging device C can be applied not only for discharging safe balls but also for discharging prize balls (such as the prize ball dispensing device 62) and discharging balls for lending, and one game ball can be used. It can be applied to a ball feed to a launching device that launches each from the upper plate and launches it toward a game board, and can also be used in a game machine that uses other types of game balls.
