Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a prize ball discharging device for a pachinko machine.

[Prior Art] The present applicant provided an upper valve and a lower valve at the upper and lower ends of a fixed case part in which a fixed number of prize balls are stored, and also provided an opening/closing operation plate that is vertically movable between the upper valve and the lower valve. The upper end of the vertical rod of the safe ball discharge treatment device, which moves upward in relation to the generation of safe balls, is connected to the opening/closing operation plate, and the upper and lower valves are alternately opened and closed by the upward movement of the opening/closing operation plate. In Utility Model Application No. 15329-1980 (Utility Application No. 59-122184), a prize ball case for a pachinko machine was proposed in which a fixed number of prize balls were released from the fixed case part.

[Problems to be solved by the invention] However, in this case, the opening/closing operation plate is directly connected to the vertical rod of the safe ball discharge treatment device, so the opening/closing operation plate is at the same distance as the upward stroke of the vertical rod by the safe ball. Therefore, high precision was required in the opening/closing operating plate and the relative positional relationship between the upper and lower valves in order to correctly release the prize balls. In other words, if the upward movement of the opening/closing operation plate can be increased, the opening/closing operations of the upper and lower valves can have more leeway, thereby making it possible to more reliably release the prize balls. becomes.

[Means for Solving the Problems] The present invention was proposed in view of the above, and the discharging actuator is moved up and down along the outside of one side wall of a vertical cylindrical fixed case part in which a fixed number of prize balls are stored. The upper valve is movably provided and is installed at the upper end inlet and lower end discharge port of the fixed case part, and the upper valve is rotated by the upward movement of the discharge actuator to close the upper end inlet, and the lower valve is installed to open the lower end discharge port. A horizontal operating rod is provided at the outside of the discharge actuator, one end of which is rotatably supported and the other end faces the recessed part of the discharge actuator, and the safe ball moves upward in relation to the generation of the safe ball. The upper end of the vertical rod of the discharge treatment device is connected to the operating rod.

[Operation] When safe balls are generated and the vertical rod of the safe ball discharge processing device is pushed upward, the operating rod also rotates upward and moves the discharge operating body upward. As a result, the upper valve rotates to close the upper end inlet of the fixed case part, and the lower valve rotates to open the lower end outlet.
A fixed number of prize balls are released from the fixed case part. At this time, the upward movement of the discharge actuator is increased compared to when the upper end of the vertical rod is directly connected to the discharge actuator, and the opening and closing operations of the upper valve and the lower valve can be performed reliably.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the back view of the pachinko machine.

A ball discharging device 5 indicates a prize ball discharging device that discharges a fixed number of prize balls in relation to the safe balls discharged by the safe ball discharging device 3.

As shown in FIG. 6, the safe ball discharging device 3 communicates with the outlet of the safe ball gathering section 4, and has a safe ball outlet passage 7 formed at the bottom as a vertical section 6 in which several safe balls are lined up in a row. The extrusion body 10 faces the bottom surface 8 of the vertical part 6 so as to be able to enter and retreat and push out the safe balls to the discharge port 9, and the swinging piece 11 is disposed on the outside of the discharge port 9. .

The extruded body 10 is formed into a horizontal T-shape by a slide frame portion 10b having a vertical groove 10a and an extruded portion 10c extending perpendicularly toward the vertical portion 6. The pin 15 of the fixed crank disk 14 is exposed.
The upper end of the swinging piece 11 is swingably supported by a shaft 16, and a downwardly hanging ball contacting part 11a is positioned opposite to the discharge port 9 so as to block the discharge port 9. A connecting arm 11b is projected, and the lower end of the vertical rod 17 is connected to this. The rear end of a horizontal locking piece 18 is rotatably supported by a shaft 19 at a position outside the ball contacting part 11a of the swinging piece 11, and its tip is formed in the ball contacting part 11a of the swinging piece 11. It is inserted into the vertically elongated hole 11c and positioned so as to protrude from the discharge port 9. Also, lock piece 18
A hook portion 20 is formed on the lower surface of the vertical hole 11c so as to be able to engage with the lower end side surface of the vertically long hole 11c, and normally the hook portion 20 engages with the lower end side surface of the vertically long hole 11c to move the swinging piece 11. It's becoming more restrictive. 21 is a safe ball discharge processing passage provided in a straight line with the discharge port 9, and 22 is a safe ball detection sensor.

Therefore, the safe balls collected in the safe ball collecting section 4 are guided to the safe ball lead-out passage 7 and then passed through the vertical section 6.
It can be received on the bottom surface 8 of. On the other hand, when the motor 12 rotates, the extruded body 10 moves to the pin 1 of the crank disk 14.
5 performs reciprocating linear motion in the horizontal direction along the guide frame 31, and the tip of the extrusion portion 10c
When the ball enters the bottom surface 8 of the vertical part 6 as shown by the chain line in the figure, the safe ball is pushed out to the discharge port 9. When the safe ball is pushed out to the discharge port 9, the safe ball contacts the locking piece 18 and rotates it upward, releasing the locking of the swinging piece 11 by the hook part 20 and locking the swinging piece 11.
Press to swing it, and by doing so, the vertical rod 17
moves upward and transmits the movement to the prize ball release device 5. The safe balls pushed out to the discharge port 9 swing the swing piece 11 and then fall into the safe ball discharge passage 21 to be discharged.
The vertical rod 17 and the lock piece 18 immediately move back to the solid line position in FIG. 7 due to their own weight.

As shown in FIGS. 2 to 5, the prize ball discharging device 5 according to the present invention includes a vertical cylindrical fixed case part 23 in which a fixed number of prize balls are stored, and a fixed case part 23 on the outside of one side wall of the fixed case part 23. an upper valve 25 and a lower valve 26 rotatably supported at a position slightly below the upper end and center of one side wall of the fixed case part 23 on the outside of the fixed case part 23;
and a horizontal operating rod 27 disposed on the side of the discharge operating body 24.

The fixed case portion 23 is the partition wall 2 in this embodiment.

It faces the connected prize ball discharge gutter 33.

The discharge actuator 24 has both side edges fixed to the case part 23.
It is supported by guide grooves 37, 37 provided on the outside and has its own weight so that it always descends.A bifurcated opening 24a is provided at the upper end, and an engaging protrusion 24b is provided at the lower end. Further, a recessed notch 24c is provided above the engaging protrusion 24b and is integrally formed.

The upper valve 25 is pivotally supported at an approximately intermediate position on the outside of the fixed case portion 23 by a shaft 34, and has a stopper piece 25a at its tip that corresponds to the upper end inlet, and its rear end is connected to the opening of the discharge actuator 24. 24a. The lower valve 26 is supported on the outside of the fixed case part 23 by a shaft 35 at the middle of its height so as to remain vertical at all times. A roller 26a is provided to
Stopper pieces 26b, 26b are provided at the lower end to face the respective ball passages 29, 29 and prevent the balls from flowing down.

The fixed case part 23 has a flange piece 36 projecting to both sides on the lower surface, and the flange piece 36 is fitted into a recess 38 formed in the mechanism plate 2, and a fixing lever 39 pivotally supported on the mechanism plate 2 is inserted into the flange piece 36. It is fixed to the mechanism plate 2 by being pressed against the flange piece 36 on one side. For this reason, the fixed lever 39
By rotating and separating from the flange piece 36, the discharge actuating body 24 is integrated with the fixed case part 23.
The upper valve 25 and the lower valve 26 can be removed from the mechanism plate 2. Further, the shaft 35 has an operating rod 40 pivotally supported at its protruding end, and the shaft 35 can be inserted into and removed from the lower valve 2 by rotating the operating rod 40.
6 can be removed.

The operating rod 27 has one end supported by a shaft 41 provided on the mechanism plate 2 on the side of the discharge operating body 24,
The other end faces the concave notch 24c of the ejection actuating body 24 and is supported so as to maintain a substantially horizontal position, and the upper end of the vertical rod 17 of the safe ball ejection processing device 3 is connected to the intermediate position thereof.

Therefore, as shown in FIG.
The rear end is pushed down by 4a and the tip ball stopper piece 25

When all the prize balls in the ball passages 29, 29 are released, the lower valve 26 returns to the vertical state due to its own weight, and the lowering of the vertical rod 17 causes the release actuator 24 to move to the operating rod 2.
The stopper pieces 26b, 26 are released from the push-up of 7 and lowered by their own weight, and the roller 26a is brought into contact with the engagement protrusion 24b to keep the lower valve 26 in the vertical state.
Close the lower end discharge ports of the ball passages 29, 29 with b. Further, the rear end of the upper valve 25 is lowered at its opening 24a as the discharge actuating body 24 descends, and the tip ball stopper piece 25 is lowered.
a moves upward to cause the prize balls to flow into the ball passages 29, 29, and thus completes the discharging and filling of a fixed number of prize balls.

As is clear from the above explanation, according to the present invention,
The upper end of the vertical rod 17, which rises in relation to the generation of safe balls, is connected to the middle of a horizontal operating rod 27 whose one end is pivoted, and the rotation of the operating rod 27 pushes the discharge actuator 24 upward. At the same time, the upper valve 25 and the lower valve 26 are opened and closed alternately to release the prize balls, so the connection position of the vertical rod 17 and the operating rod 27 and the length of the operating rod 27 are selected. This makes it possible to freely increase the stroke of the discharge actuator 24.
