DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game ball prize detection device which can reliably detect as a electrical signal whether or not a game ball fired on a game board in a pachinko game machine has a prize.

[0002]

2. Description of the Related Art In a pachinko game machine, an electromagnetic proximity sensor utilizing an electromagnetic induction phenomenon has been used to detect that a game ball has entered a ball receiving port provided on a game board. When the ball is detected by the sensor and an electric signal is output, for example, a symbol variation display device such as a CRT is activated, and the symbols on the display device are accidentally aligned with a certain number or symbol by a certain probability. In addition, it is configured so as to obtain a privilege such as a so-called big hit and a big winning opening. There are also various types of winning opening variable opening / closing devices provided on a game board that are activated by the sensor outputting an electric signal to give a privilege to a player.

[0003]

A conventional game ball winning detection device in a conventional pachinko game machine as described above,
There is a risk of malfunction due to receiving electromagnetic noise emitted from a wireless device such as a mobile phone, or a suspicious player illegally activates a device that gives a privilege such as a symbol variation display device by intentionally emitting electromagnetic noise. There was a risk of doing so. Also,
Since the game ball that entered the ball entrance passes near the sensor in a very short time, even if it is rarely won, the game ball may not be detected, which is disadvantageous to the player and causes trouble. There was also an event to wake up.

Accordingly, an object of the present invention is to provide a highly reliable game ball prize detection device capable of reliably detecting the presence or absence of a game ball prize in a pachinko gaming machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a game board of a pachinko gaming machine. In the drawing, reference numeral 1 denotes a symbol variation display device comprising a display such as a CRT and a liquid crystal, 2 denotes a game ball winning detection device according to the present invention, 3 denotes a door having a solenoid ( (Not shown). In addition, 5 is a windmill, 6 is a normal winning opening, 7 is a lamp, and 8 is an out ball discharge outlet.

As shown in FIGS. 2 to 4, the game ball prize detecting device 2 has a ball receiving port 21 integrally formed on the front surface of the mounting substrate 20, and the ball receiving port 21 is formed by an electromagnetic proximity sensor. A ball detection sensor 22 is provided, and the ball receiving port 21 is provided.
A guide tube 23 bent in a V-shape so as to extend further downward is formed integrally with the ball receiving port 2 at the lower end opening of the guide tube 23.
An opening / closing piece 24 for temporarily stopping the game ball entered from 1 is provided. Reference numeral 25 denotes a stationary ball detection sensor provided to detect a game ball parked on the opening / closing piece 24.

The opening / closing piece 24 is rotatably supported in a vertical plane by a support shaft 26 laid on the mounting board 20, and an engagement shaft 27 integrally formed at the rear of the opening / closing piece 24.
, The tip of the tilting rod 28 is loosely fitted. The tilting rod 28 is tiltably supported on a support shaft 29 laid on the back side of the mounting board 20 so as to be parallel to the support shaft 26. Then, the mounting plate 31 is fixed to the back side of the mounting substrate 20 with the screw 30.
The operating rod 3 of the solenoid 32 mounted on the mounting plate 31
3 and a pin 36 provided on the connecting piece 34
Connects the rear end of the tilting rod 28.

For this reason, as shown in FIGS. 2 and 3, when the solenoid 32 is in the demagnetized state and the operating rod 33 is protruding, the head 24a of the opening / closing piece 24 hits the game ball entered from the ball receiving port 21 and the game ball is hit. To prevent the outflow. When the solenoid 32 is excited and the operating rod 33 is retracted, the tilting rod 2
As shown in FIG. 4, the game ball is received in the concave portion 24b of the opening / closing piece 24 since the tilting of the opening / closing piece 8 causes the opening / closing piece 24 to rotate and the head 24a to retreat. Then, when the solenoid 32 is demagnetized again, the state returns to the state of FIG. 3 and the game ball is opened downward. Therefore, each time the solenoid 32 is excited once, one game ball is discharged from the lower end opening of the guide cylinder 23.

As shown in FIG. 5, the pachinko gaming machine includes a game control circuit 40 including a CPU (microprocessor), a ROM (read only memory), an input / output interface, an output driver, and the like. When the CPU executes the program relating to the recorded game content, the CPU detects the winning of the game ball in the ball receiving port 21, activates the symbol variation display device 1, generates a jackpot with a predetermined probability, and gives the player Benefits are granted. FIG. 5 is a block diagram showing only parts related to the present invention. In FIG. 5, the same reference numerals as those in FIGS. 1 to 4 indicate the same parts.

FIG. 6 shows a flowchart of the game ball winning detection device performed by the game control circuit 40. Next, the game ball winning detection procedure according to the present invention will be described with reference to this flowchart. When a game ball enters the ball receiving port 21 and an electric signal is output from the passing ball detection sensor 22 (step a), a passing timer (0.5
(Set on the order of seconds) is activated, and a symbol variation display of the symbol variation display device 1 is activated. The game ball that has entered the ball receiving port 21 flows down the guide tube 23 and stays on the head 24a of the opening / closing piece 24. In step b, it is determined whether an electric signal is output from the stationary ball detection sensor 25 within the set time of the passage timer. If the electric signal is output within the set time, the operation of the passage timer is stopped. , A stationary timer similarly configured in the CPU (set to about 0.1 second)
To start. When the set time of the stop timer elapses (step c), the stop timer stops operating and the solenoid 32 is excited to discharge the game ball stopped on the opening / closing piece 24. On the other hand, if the stopped ball detection sensor 25 does not operate within the set time of the passage timer in step b, the above benefits are invalidated, an error is displayed on the symbol variation display device 1, and the hit ball firing motor is stopped. Perform error processing such as

In this case, since the game ball entering the ball receiving port 21 can be repeatedly detected by the stationary ball detection sensor 25 while parked on the opening / closing piece 24, the winning can be reliably detected. In addition, since the guide tube 23 is bent to prevent the game ball from hitting the opening / closing piece 24 and bouncing, it is effective in preventing detection errors by the stationary ball detection sensor 25 more reliably.

[0013]

[0014]

As described above, according to the present invention, once the game ball is stopped by the opening / closing piece, it is possible to reliably detect that the game ball has entered the ball receiving port, and malfunction due to electromagnetic noise or the like. There is no wake up. For this reason, there is a remarkable effect in preventing troubles related to the presence of a prize, fraud or the like.
