Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention rotates a rotating body by driving a motor, and the rotating body transports safe balls to a discharge path and operates a prize ball release device. The present invention relates to a safe ball discharge control device for a panko machine.

[Conventional technology]

Conventionally, a safe ball discharge control device using this type of rotating body is known, for example, from Japanese Patent Publication No. 55-41791.

As shown in FIG. 12, this conventional safe ball discharge control device includes a drive plate 102 fixed to a motor shaft 101 of a motor 100 and constantly rotated with the rotation of the motor 100, and a cam loosely fitted to the motor shaft 101. A recessed part 104 formed in each of the driving plate 102 and the cam moving plate 103.
When a and 104b are in the same phase, safe ball guide gutter 1
At 07, the waiting safe ball B is in the double concave notch 104a,
104b, the safe ball B acts as a clutch member and both discs 102 and 103 are rotated together. As the cam disk 103 rotates, its cam convex portion 103a contacts the interlocking surface 105a of the control plate 105 and moves the control plate 105 upward as shown by the chain line in the figure. The prize balls in the prize ball case are released through the push-up link 106.

[Problem to be solved by the invention]

In this conventional pachinko machine safe ball discharge control device, the prize balls from the prize ball case are released by the upward movement of the control plate 105, so for example, the cell board, piano wire, etc. There was a problem in that a fraudulent act could easily be carried out by inserting a button and moving the control board 105 upward, thereby causing the prize balls to be released.

A safe ball control device for a pachinko machine that is equipped with a swinging body that engages with a lever that has the same type and effect as the control plate 105 described above and restrains it in an inactive position is known, for example, from Japanese Utility Model Application Publication No. 180478/1983. ing. However, in this conventional device, the swinging body and lever are moved by the safe ball, so if a broken ball or a small diameter ball becomes the safe ball, the swinging of the swinging body may become incomplete. There is a problem in that the winning ball cannot be released after all because the lever cannot be completely disengaged from the lever.

The present invention can completely prevent fraudulent acts such as moving the control board upward using a cell board or piano wire to release prize balls, and can also reliably release prize balls every time a safe ball occurs. The purpose of this invention is to provide a safe ball discharge control device for such pachinko machines.

[Means to solve the problem]

In order to achieve the above object, in the safe ball discharge control device for a pachinko machine of the present invention, a pair of a first rotary body and a second rotary body are arranged concentrically facing each other at the end of the safe ball discharge passage. Place the first
The rotating body is fixed to the motor shaft of the motor, and the second rotating body is loosely fitted to the motor shaft and supported in a free state, and the outer peripheries of the first rotating body and the second rotating body are aligned with each other. A recessed portion capable of accommodating safe balls guided from the safe ball discharge passage is provided near the second rotating body, and is engaged with an operating member for operating a prize release device and this operating member. A lock piece that restrains the clock piece in an inoperable manner is swingably supported, and the second rotary body has a protrusion that engages with the actuating member and a protrusion that abuts the clock piece and causes the actuating member to release the restraint. It is provided with an engaging part that moves the operating member and releases the prize.

[Effect]

The actuating member is normally restrained in an inactive position in which it is impossible to release the prize by engagement with the lock piece, and the actuating member is restrained by the engagement of the lock piece in an inactive position where it is impossible to eject the prize. When rotated, the restriction is released, and the engaging part swings to enable the prize to be ejected. In this way, the action of releasing the prize by the operating member is impossible unless the restraint by the lock piece is released, making it possible to completely prevent fraudulent activities using the cell plate or piano wire. In addition, since the lock piece and the operating member are moved not by the safe ball but by the protrusion and engagement part provided on the second rotating body, the ejection operation of the prize ball can be performed reliably. It becomes possible.

He was depressed and taken to prison between 9 and 9. When the safe ball B moves through the recess 28 of the first rotating body 21 and reaches the end of the recess 29 of the second rotating body 22, the safe ball B stops the rotation of the first rotating body 21. It is transmitted to the second rotating body 22 and rotates together as one.

As the second rotating body 22 rotates, its projection 30 comes into contact with the contact piece 26b of the lock piece 26, causing the lock piece 26 to rotate upward as shown in FIG. The engagement between the joint portion 34 and the hook portion 32 of the actuating member 24 is released. Then, the second rotating body 22
continues to rotate, the roller 3 of the second rotating body 22
1a contacts the cam surface 33 of the actuating member 24, and the actuating member 24 is swung upward by the inclined surface of the cam surface 33 as shown in FIG. As a result, the vertical rod 7 is pushed upward to open the valve member 8 of the prize release device 5 and release the prize. Then, when the roller 31a of the second rotating body 22 separates from the cam surface 33, the operating member 24 and the locking piece 26 first return to the position shown in FIG. The hook portion 32 of the actuating member 24 engages with the actuating member 24 to again restrain the actuating member 24 in the inactive position, and then the safe balls B are discharged into the discharge path 38. Also,
At the same time as the safe balls B are discharged into the discharge path 38, the transmission of the rotation of the first rotary body 21 to the second rotary body 22 is cut off, and the rotation of the second rotary body 22 is stopped.

〔Effect of the invention〕

As explained above, the safe ball discharge control device for a pachinko machine of the present invention fixes the first rotating body to the motor shaft of the motor, and supports the second rotating body in a free state by freely mounting it on the motor shaft. , the rotation of the first rotating body is transmitted to the second rotating body by the safe balls that fall into the recesses formed in the first rotating body and the second rotating body, and the locking piece is brought into contact with the second rotating body. A projection part and an engaging part that engages with the operating member are provided, and the rotation of the second rotating body causes the lock piece to release the restraint of the operating member and the operating member to release the prize. Since the actuating member is always restrained in the inactive position by the lock piece when the second rotating body is stopped, the actuating member is moved using a cell plate or piano wire, Fraudulent acts such as releasing prizes can be completely prevented.

Further, since the lock piece and the operating member are operated by the protrusion and the engaging portion provided on the second rotary body regardless of the safe balls, the ejection operation of the prize balls is ensured.

Furthermore, it is possible to set a time lag between the release of the restraint of the operating member by the lock piece and the operation of releasing the prize by the operating member, thereby increasing precision in the relative positional relationship between the lock piece and the operating member. This simplifies the assembly work and guarantees high operational reliability.
