DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a ball fixing mechanism in a pachinko ball firing device for a pachinko game machine.

[0002]

2. Description of the Related Art A conventional ball launching device for a pachinko game machine includes:
The pachinko balls stored in the upper plate of the gaming machine are sent out one by one from the hitting ball supply device operating in synchronization with the firing device onto the firing rail, and the released pachinko balls fall on the firing rail, and the lower end of the rail. Rolls down until it collides with a stopper fixed at the launch position located at, and then jumps out onto the game board with the launch device. In order to eliminate the vibration of the ball, the stopper is made of an elastic body, or the stopper is made of a leaf spring.

[0003]

The firing interval of the pachinko balls is about 50 shots per minute. Therefore, it takes 0.5 seconds for the sent pachinko balls to roll on the firing rail and be locked by the stopper. It is necessary to stop the vibration and the bounce generated when the stopper collides during this time. However, even if it is made of an elastic material, even if it can attenuate vibrations and bounces, it will not stop in a short time of 0.5 seconds, which causes a slight variation in the firing speed of pachinko balls. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a ball fixing mechanism capable of minimizing vibration of a pachinko ball stopper, which has been a cause of variation in firing speed in view of the drawbacks of the prior art.

[0004]

That is, the present invention supplies a firing rail fixed in an inclined state and balls stored in an upper plate installed above the firing rail one by one to the firing rail. Hitting ball supply device discharge port, a stopper made of an elastic body installed at the lower end of the firing rail, a hammer that shoots the pachinko ball locked by the stopper toward the game board, and near the lower end of the firing rail A pachinko ball launching device comprising an arranged electromagnet, wherein the electromagnet is configured to be excited until immediately after the pachinko ball is sent out of the hitting ball supply device discharge port and the hammer activates to launch the pachinko ball. This object is achieved by a ball fixing mechanism in the device. According to a second aspect of the present invention, when the excitation of the electromagnet is turned ON / OFF, a current flows for a predetermined time t from a point in time when the pachinko ball falls from the discharge port of the hit ball supply device, and after t seconds elapses, the current supply is interrupted. It is controlled by a control device configured as described above. The invention according to claim 3 is a pachinko ball detecting means provided near the discharge opening of the hit ball supply device, wherein ON / OFF of the excitation of the electromagnet is provided;
And a hammer detecting means for detecting that the hammer for firing the ball has approached the vicinity of the stopper, from the time when the pachinko ball detecting means detects until the hammer detecting means detects the hammer, and ON. Is turned off by a control device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a schematic front view showing the structure of a launching device portion in a pachinko gaming machine. Reference numeral 1 denotes a launching rail that is inclined upward in the game board direction, and a hitting ball supply device discharge port 2 is provided above the launching rail 1. The pachinko balls 6 are sent out one by one from the outlet. Reference numeral 3 denotes a stopper formed of an elastic body for locking the sent-out pachinko balls in the vicinity of the lower end of the firing rail 1. The distance between the lowermost end of the stopper 3 and the rolling surface of the firing rail 1 is pachinko. It is designed to be smaller than the diameter of the ball 6. Reference numeral 4 denotes an electromagnet fixed at a position close to the pachinko ball 6 locked by the stopper 3 (a position at which the magnetic field of the electromagnet affects the ball 6). Reference numeral 5 denotes a hammer for firing a pachinko ball, which is a predetermined number of times specified by law.
And is known.

In the above-described configuration, the pachinko ball 6 discharged from the hitting ball firing device discharge port 2 falls to the firing rail 1. At this time, the electromagnet 4 is not energized (FIG. 2). Thereafter, the pachinko ball 6 rolls toward the stopper 3 according to the inclination of the firing rail 1. When the pachinko ball 6 comes to the vicinity of the stopper 3, the control device 8 operates to energize the electromagnet 4 and excite it to the N pole or the S pole (FIG. 3). After that, the pachinko ball 6 comes into contact with the stopper 3 and attempts to bounce or vibrate by reaction. However, since the electromagnet 4 is excited, the pachinko ball 6 is attracted by the magnetic force of the electromagnet 4 and comes into contact with the stopper 3. It will be stopped at the position where it was set (FIG. 4). When the hammer 5 of the firing device approaches the firing position for hitting the pachinko ball 6, the detecting means of the control device 8 detects this and turns off the pachinko ball 6 to cut off the power supply to the electromagnet 4. State
In this state, the hammer 5 of the launching device hits the pachinko ball 6 (FIG. 5), so that the ball 6 jumps out without resistance.

In the embodiment shown in FIG. 1, a detecting means 8a for the pachinko ball 6 is provided near the stopper 3, and a detecting means 8b for the hammer 5 is provided on the movement trajectory of the hammer 5, and the detection signal is controlled. It is transmitted to the device 8. As a result, pachinko balls 6
An ON signal flows to the control means 8 as a detection signal when the signal crosses the detection means 8a, and an ON signal is supplied to the control device 8 to cross the detection means 8b when the hammer 5 is pulled back for hitting.
Flows to As a result, the control device 8 supplies a current to the electromagnet 4 to excite the magnet. Then, the electromagnet 4 becomes the N pole or the S pole, and attracts the pachinko ball 6 near the stopper 3 by magnetic force and stops.

In a stationary state, when the launching device operates and the mallet 5 approaches the ball 6 to hit the ball 6, the detection device 8b crosses the detecting device 8b, and an ON signal is transmitted from the detecting device 8b to the control device 8. Is done. Then, the control device 8 cuts off the power supply to the electromagnet 4 so that the restraint of the pachinko ball 6 by the electromagnet 4 is released, and the ball 6 in the free state is fired toward the game board by the hammer 5 hitting. Ball 6 fired
Again crosses the detecting means 8a, and an ON signal is transmitted to the control device 8, but is ignored as an ON signal transmitted within a predetermined time (for example, 0.01 second) after the ON signal of the detecting means 8b. .

Further, the control device according to the present embodiment is configured such that the flow of the current to be supplied is switched every time in order to prevent the magnetization of the electromagnet 4. Further, in this embodiment, the installation position of the electromagnet 4 is set below the firing rail 1, but the present invention is not limited to this. The position where the pachinko ball 6 locked by the stopper 3 can be stopped by magnetic force. Then, it goes without saying that it may be installed not only below but also on the side. Further, ON / OFF of energization to the electromagnet 4 by the control device 8 is determined by the detection means 8a,
Although the control is performed based on the detection signal from the detection unit 8b, the present invention is not limited to this, and the control is performed such that the power is supplied for a predetermined time (for example, 0.3 seconds) after receiving the detection signal from the detection unit 8a. You may. Although the control device of the launching device controls the timing of the hammer 5, the power may be turned off by transmitting the timing at which the hammer 5 operates for hitting to the control device 8.

[0010]

As described above, according to the ball fixing mechanism in the pachinko ball firing device according to the present invention, the vibration and jumping of the pachinko ball immediately before firing can be stopped and stabilized, so that the player can always play the ball. Since the ball of the same speed can be fired, accurate ball flight can be realized.
