Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a game board mounted with a ball receiving device for receiving and passing a pachinko ball hit on a game board surface.

[0002]

2. Description of the Related Art In a ball receiving device of this kind of a conventional pachinko machine, a pachinko ball dropped from the game board surface into a ball receiving portion of a rotating body of the ball receiving device is temporarily stopped in the ball receiving portion and then re-opened. It was configured to be returned to the game board surface.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a pachinko machine having a novel idea with respect to the mode of passage of winning balls dropped from the game board surface into the ball receiving device.

[0004]

The pachinko machine of the present invention comprises:
One winning ball can be received and released after staying, and a rotating body formed with a ball receiving portion that turns along the game board surface, a motor that rotationally drives this rotating body, and the ball receiving portion is released. And a ball guideway that guides the winning ball to the rear of the game board,
A ball receiving device having a ball detecting switch for detecting a winning ball that has passed through the ball guide path is installed on the game board surface.

[0005]

When the winning ball is dropped into the ball receiving portion which is formed on the rotating body which is driven to rotate by the motor and swivels along the game board surface, the winning ball is released from the inside of the ball receiving portion after being stopped and the ball guiding path. Is guided to the rear of the game board surface, and the ball detection switch detects a winning ball that has passed through the ball guide path and transmits a detection signal.

[0006]

Are formed by notches, and lead wire insertion / removal portions 37a are formed at the outer ends of the respective lead wire holding grooves 37 for lateral insertion and insertion / removal of the lead wire bundle. Lead wire holding portions 37b, which are connected to the lead wire inserting / removing portion 37a in a bent state and hold a lead wire bundle, are formed at the ends, respectively.

Next, the game specifications of the pachinko machine of this example will be described. When the pachinko balls fired on the game board surface 1a enter the starting winning opening 24 of the ball receiving device 10, six pachinko balls are paid out, Pachinko ball is the center prize hole 2
When 13 a, a big winning opening 3a, a top winning opening 4a, an upper left winning opening 5a, a lower left winning opening 6a, a symbol operating opening 7a, and a specific winning opening 8a are won, 13 pachinko balls are set to be paid out.

When the power of the pachinko machine is turned on, the middle rotor 2c of the central winning device 2 starts a counterclockwise rotation operation, and the rotor 25 of the ball receiving device 2 starts a clockwise rotation operation.

When the pachinko ball falls into the center winning opening 2a of the central winning device 2, the winning ball passes through the upper plate passage opening 2c and the seven passage openings 2e of the rotating middle rotating body 2d and the gate 2f. Fall into one of them.

When the winning ball that has won the center winning hole 2a of the central winning device 2 passes through the gate 2f or the pachinko ball wins the symbol working opening 7a of the interlocking accessory 7, the symbol display body 2b shows the left symbol. , The middle symbol, the right display of the variable display is started, and when 29.85 seconds or more has elapsed from the start of the variable display of the symbol, the symbol display body 2b stops the variable display of the symbols in the order of the left symbol, the middle symbol, and the right symbol.

However, when the variation time reduction button is operated, the symbol display body 2b displays the variation of the symbols in the order of the left symbol, the middle symbol, and the right symbol when 0.9 seconds or more has elapsed since the variation time reduction button was operated. To stop.

The special winning opening 8a of the ordinary electric accessory 8 except when the left symbol, the middle symbol, and the right symbol when the symbol display 2b stops the variable display of the symbol are 0, 0, 0 Is released for 5.8 seconds, and the retaining member 9c of the lower right winning device 9 operates for 8 seconds.

During variable display of symbols by the symbol display 2b,
Alternatively, while the specific winning opening 8a is open, the center winning opening 2a
When the winning ball to pass through the gate 2f newly, or when the pachinko ball newly wins the symbol operation opening 7a of the interlocking accessory 7, the number of times is stored up to 4 and is displayed by the stored number display LED 2g. Then, after the variable display of the symbols is stopped or after the opening of the specific winning opening 7a is finished, the symbol display body 2b starts the variable display of the symbols.

The winning ball that has won the specific winning opening 7a that has been opened and has dropped into the lower right winning device 9 passes through either the left or right passage opening 9b or the special device operating area 9a.

When the winning ball passes through the left and right passage openings 9b, only a specified number of pachinko balls are acquired, and when the winning ball passes through the special device operating area 9a, the special device operates.

A pachinko ball enters the starting winning opening 24 of the ball receiving device 10 while the special device is operating, and the passing ball detection switch 3
When detected by 0, the special winning opening 3 of the middle-lower winning apparatus 3
a is opened for 9.8 seconds. However, when 10 of the pachinko balls are won in the open special winning opening 3a, the special winning opening 3a is closed at that time.

The operation of the special device is stopped when 16 pachinko balls enter the starting winning opening 24 of the ball receiving device 10 during the operation of the special device or when the winning balls pass through the special device operating area 9a again. When the operation of the special device is stopped during the opening of the special winning opening 3a, the special winning opening 3a is opened for the remaining time.

Next, the operation and effect of the embodiment having the above-mentioned structure will be described. In this example, one winning ball is received and stayed in the ball holding cover 13 that is connected to the front surface of the base plate 12 of the ball receiving device 10 installed on the game board surface 1a and has the starting winning opening 24. A rotating body 25 having a recessed ball receiving portion 26 that can be discharged and swivels along the game board surface 1a is inserted, and the rotating body 2 is mounted on the back plate 14 coupled to the rear end of the base plate 12.
A motor 36 for rotationally driving 5 is attached to the base plate 12, and the winning ball discharged from the ball receiving portion 26 is guided to the rear of the game board surface 1a and introduced into the detection opening 30a of the passing ball detection switch 30. 20 is formed, and the special winning opening 3a is opened for a predetermined time based on the detection signal of the passing ball detection switch 30.

Therefore, it is possible to add a new idea to the mode of receiving and passing the pachinko ball from the game board surface 1a into the ball receiving device 10, and at the same time, to receive the pachinko ball received in the ball receiving portion 26 of the rotating body 25. Since it can be detected by the passing ball detection switch 30 by guiding it to the rear of the game board surface 1a, the game specification can be achieved by controlling the operation of various electric members assembled to the game board 1 by the detection signal of the passing ball detection switch 30. Can be changed in various ways.

The fixed position detection switch for detecting the turning position of the ball receiving portion 26 of the rotating body 25, and the detected object detected by the fixed position detection switch by turning in the same turning manner as the turning manner of the ball receiving portion 26. The body is provided in the ball receiving device, and the ball receiving portion 2
The motor 36 and the rotating body 25 may be stopped or started in a state in which the 6 has swung to the origin position (top dead center).
