Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for supplying a prize ball to a prize ball storage tank of a pachinko machine.
[0002]
[Prior art]
A device for supplying premium spheres to a premium sphere storage tank provided on the upper back side of the front frame of a pachinko machine is conventionally known from Japanese Utility Model Publication No. 4-92282, Utility Model Registration No. 2521179, and the like. When the front frame of the pachinko machine is opened forward in the event of a failure, the shield plate blocks the replenishment path by spring biasing, preventing the refill ball from spilling out of the storage tank and closing the front frame as it was Then, the lever is pressed by the prize ball storage tank, the blocking plate is retracted, the supply port is opened, and the supply of the supply ball is resumed.
[0003]
[Problems to be solved by the invention]
By the way, in the prize ball supply device of the conventional pachinko machine, there is a possibility that supply balls on the secondary side of the shielding plate may spill out when the front frame is opened.
In addition, some of the conventional prize ball replenishing devices do not have a blocking plate and simply bend the replenishment port upward to prevent the replenishment balls from flowing out. It was inevitable that spills were not completely blocked.
[0004]
[Means for Solving the Problems]
A premium ball supply device for a pachinko machine according to the present invention intends to solve the above-mentioned problem. An elbow is fixed to a mounting plate of a supply ball counter, and the supply balls discharged from the supply ball counter are horizontally aligned. The replenishing nozzle is supported so as to be rotatable in a vertical plane around the discharge port by making the communication port opened on one side face the discharge port of the elbow. A spring is provided to urge the nozzle from the downward tilted position to the upward position, and a slit hole is formed on the upper surface near the tip of the replenishing nozzle, and enters the slit hole when the replenishing nozzle is in the upward position. A cantilever in which the ball stop piece is fixed to the mounting plate and the rear end of the replenishing nozzle is in contact with the premium sphere storage tank and the replenishing nozzle is tilted downward so that the front end faces the premium sphere storage tank. It is characterized by being fixed That.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the back upper part of this pachinko machine island, FIG. 2 shows a longitudinal section of the main part thereof, FIG. 3 shows an operation state thereof, and FIG. 4 shows a perspective view of the main part. 1 is a prize ball distribution rod, 2 is a distribution hose hanging from the distribution rod 1, 3 is a belt plate disposed horizontally on the machine frame 4, 5 is a front frame of a pachinko machine, and 6 is the front surface A game board provided on the frame, 7 is a prize sphere storage tank, and 8 is a prize sphere outlet.
[0006]
Reference numeral 10 denotes a mounting board fixed to the belt plate 3 by screws 11, 12 denotes a mounting board detachably provided on the mounting board 10, and the mounting board 12 is bent at one end edge of the engaging portion 13. Is engaged with the back surface of the mounting substrate 10, and a wing nut 15 is fastened to the long hole 14 formed in the bent edge at the other end, and the wing nut 15 is loosened to thereby reduce the range of the long hole 14. It is fixed so that the height can be adjusted inside. Reference numeral 16 denotes a supply ball counter provided on the mounting plate 12. The supply ball counter 16 engages one end edge with an engagement piece 17 bent on the attachment plate 12 and the other end edge portion. The handle 18 is detachably fixed to the mounting plate 12 by pressing the provided handle 18. A connecting pipe 19 is provided at the upper sphere inlet of the replenishing sphere counter 16 to connect the distribution hose 2. In addition, a sprocket that rotates when the sphere passes is provided in the replenishing sphere counter 16, and the number of passing spheres is output as an electric signal by the rotation.
[0007]
Reference numeral 20 denotes an elbow fixed to the mounting plate 12 by a screw 21 so as to face the lower ball discharge port of the supply ball counter 16. The elbow 20 horizontally supplies the supply ball discharged downward from the supply ball counter 16. Lead to. A replenishing nozzle 22 guides the replenishing sphere received from the elbow 20 to the premium sphere storage tank 7. The supply nozzle 22 is formed by connecting a base portion 22a and an extension portion 22b with screws 23, and is opened on one side of the supply nozzle 22 as shown in FIG. 5 so that the communication port 24 faces the discharge port 25 of the elbow 20. At the same time, a shaft portion 26 protruding from the opposite side wall of the communication port 24 is rotatably supported by a bearing body 27 fixed to the mounting plate 12 by screws 28.
[0008]
A slit hole 29 is formed on the top surface of the replenishing nozzle 22 as shown in FIG. Reference numeral 30 denotes a cantilever that is fixed to the rear end portion of the supply nozzle 22 with a screw 31 and extends in a direction substantially orthogonal to the supply nozzle 22. Reference numeral 32 denotes a coiled spring that is wound around the shaft portion 26 and urges the replenishing nozzle 22 from a downward inclined position to an upward position by fixing one end to a screw 28 and the other end to a cantilever 30. is there. Reference numeral 33 denotes a bowl-shaped ball stop piece projecting from the front surface of the mounting plate 12, and the ball stop piece 33 enters the slit hole 29 when the supply nozzle 22 is in the upward posture.
[0009]
In the premium ball supply device of the pachinko machine configured as described above, the premium ball of the premium ball distribution basket 1 reaches the elbow 20 through the distribution hose 2, the connecting pipe 19, and the supply ball counter 16. In addition, it is guided into the supply nozzle 22 from the communication port 24. When the front frame 5 is closed, as shown in FIG. 2, the prize ball storage tank 7 contacts the rear side wall of the cantilever 30 and the replenishment nozzle 22 is inclined downward against the elasticity of the spring 32. Therefore, the tip of the replenishing nozzle 22 faces the prize sphere storage tank 7 and is ready to replenish the prize sphere in the prize sphere storage tank 7, and the prize sphere in the prize sphere storage tank 7 is the prize sphere. The prize sphere is replenished from the replenishing nozzle 22 as it is paid out to the player via the lead rod 8, so that the prize sphere in the prize sphere storage tank 7 is always at a constant level.
[0010]
When the front frame 5 is opened in the event of a failure or the like, as shown in FIG. 3, the prize sphere storage tank 7 is separated from the cantilever 30, and the replenishing nozzle 22 assumes an upward posture due to the elasticity of the spring 32. The ball stop piece 33 enters the slit hole 29 of the nozzle 22 and closes the supply nozzle 22. Therefore, at the same time as the tip of the replenishment nozzle 22 moves away from the premium sphere storage tank 7, as shown in FIG. 3, the outflow of the replenishment sphere is completely stopped so that the replenishment sphere spills out of the premium sphere storage tank 7. There is no such thing. When the front frame 5 is closed again after the inspection of the failure or the like is completed, the prize ball storage tank 7 comes into contact with the cantilever 30 and returns to the state shown in FIG.
[0011]
In addition, in the prize ball supply device of this pachinko machine, an elbow 20 is provided, and a discharge port 25 of the elbow 20 is communicated with a communication port 24 opened on one side of the supply nozzle 22, and the supply is performed around the discharge port 25. Since the nozzle 22 is rotatable in the vertical plane, the replenishment of the prize sphere can always be performed smoothly even though the flow path is bent. Further, the ball stop piece 33 enters from the slit hole 29 formed on the upper surface near the tip of the supply nozzle 22 when the supply nozzle 22 is in the upward posture. The supply ball inside can be closed almost without spilling out.
[0012]
【The invention's effect】
Thus, according to the prize ball supply device of the present invention, since the supply ball is not spilled when the front frame is opened, there is a beneficial effect of facilitating the opening and closing operation of the front frame when a failure occurs.
