Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric pachinko ball launching device for a pachinko machine called a digital pachi.

[0002]

2. Description of the Related Art A pachinko machine installed in a recent pachinko hall is provided with a display composed of a large number of display elements such as a CRT and a liquid crystal at the center of a game board surface, and when a hit ball enters a predetermined start winning opening, The three-digit numbers, symbols, etc. displayed on the display fluctuate so that they all rotate at the same time, and after a predetermined time, the rotation stops, and with a certain probability such as "7, 7, 7". If the pattern is aligned, it becomes a so-called big hit and the big winning opening on the game board surface is opened by the operation of the solenoid, making it extremely easy for the hit ball to enter, which is configured to be advantageous to the player (digital pattern Is called).

The above-mentioned special winning opening has a control circuit so that it closes when 10 hit balls enter, but a special area called a so-called V zone is further provided in the special winning opening. When the ball hits the zone, the special winning opening closes once, but opens immediately so that it is easier to hit the ball again. The control circuit of the microcomputer is constructed so that the special winning opening is continuously opened up to 16 times by such V zone winning. Therefore, once a big hit occurs, a large number of prize balls are paid out within a few minutes or a few pickups, which brings great benefits to the player.

[0004]

By the way, whether or not to be a big hit is usually determined by a random number that a microcomputer obtains at the start of symbol variation, so that the big hit can be obtained by adjusting the timing when the hit ball enters the starting winning opening. It is said that it may come out easily. For this reason, some players have finely controlled the timing of touching the touch-type operation lever in the electric pachinko ball launching device, and even some people carry the electronic metronome necessary for that purpose. However, since the act of adjusting the timing of hitting the ball by the player in this way is not an act of cheating, there is no choice but to tolerate it, but between the player who does not use such means and the player who does not use it. Could cause injustice.

Therefore, the present invention provides a pachinko ball launching device constructed so that it is difficult to adjust the launch timing of the pachinko machine, and the above-mentioned actions are to be stopped.

[0006]

Therefore, in the pachinko ball launching apparatus of the present invention, the electric actuator is started by operating the operating lever of the pachinko machine and the operating state is continued to drive the mallet by the electric actuator. In a pachinko ball launching device in which a fixed number of shots are shot at a fixed time, a timer that delay time is not specified is provided, and the time from operating the operating lever to starting the electric actuator is not specified. It is characterized by being trained. Further, the present invention is characterized in that the electric actuator in the pachinko ball launching apparatus is a motor. Further, the present invention is characterized in that the electric actuator in the pachinko ball launching apparatus is a solenoid. Furthermore, the present invention is characterized in that the delay time in the pachinko ball launching device is set to an unspecified time of 0.6 seconds or less.

[0007]

The function of controlling the timing of ball hitting becomes uncontrollable due to the unspecified delay time of the timer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a pachinko ball launching device attached to the back of a pachinko machine. In the figure, 1 is a mallet that is reciprocally movable by a spindle 2, 3 is a stopper that limits the reciprocating range of the mallet 1, Reference numeral 4 is a striking portion at the tip of the mallet 1 facing the launch rail 5. Reference numeral 6 denotes a coil-shaped spring that biases the mallet 1 in one direction, and the other end of the spring 6 is wound around a tension adjusting machine 7.
Reference numeral 8 denotes an operation lever projectingly provided on the front surface of the pachinko machine. One end of the rope 10 is fixed to a pulley 9 provided on the rotary shaft of the operation lever 8 and the other end of the rope 10 is fixed to the tension adjuster 7. Has been done. Therefore, the tension of the spring 6 can be adjusted by rotating the operation lever 8.

Reference numeral 11 is a step motor which is an electric actuator, and a curved cam 13 is fixedly attached to a rotary shaft 12 thereof. 14 is a lever 1 so as to be integrated with the mallet 1.
5, the pin 14 is normally located on the rotation track of the cam 13, and when the cam 13 rotates forward in the direction shown by the arrow, the pin 14 is pressed by the cam 13 and springs. 6, the mallet 1 is swung in the direction of the arrow about the support shaft 2 as a fulcrum, and when the cam 13 is further rotated, the pin 14 is disengaged from the cam 13 and returned to its original position by the elasticity of the spring 6, and the firing rail 5 The pachinko ball 15 of is hit and fired.

As shown in FIG. 2, the step motor 11 is a motor (also called a pulse motor) which rotates by one step angle with respect to one input pulse signal from the control circuit 16.
Therefore, the step angle of this kind of step motor is 1.
There are various degrees from 5 degrees to 45 degrees, but in this embodiment, 1
Use one that rotates 7.5 degrees per pulse. Therefore, the control circuit 16 requires 48 pulses to rotate the step motor 11 once, and outputs 80 pulses to the step motor 11 per second to rotate 100 times per minute. Therefore, 100 pachinko balls are hit and fired per minute.

The operation lever 8 is provided with a well-known touch detection circuit 17 for detecting that the player touches the hand, and the touch detection circuit 17 and the control circuit 1 are provided.
A timer 18 is provided between the timer 6 and the timer 6. The timer 18 delays the detection signal of the touch of the hand on the operation lever 8 obtained from the touch detection circuit 17 by an unspecified time in the range of 0 to 0.6 seconds and transmits it to the control circuit 16. Each time there is a signal, a random number is obtained from the microcomputer, and the delay time is set to 0.2 seconds, 0.4 seconds, 0.6 seconds, or 0 seconds, for example. The touch detection signal is transmitted to the control circuit 16 after a specified delay time.

Next, the operation of this pachinko ball launching device will be described with reference to the flow chart shown in FIG. Operating lever 8
When the hand is continuously touching, step (a),
By going around the loop of (b), the control circuit 16 becomes 8
0 pulse is output to the step motor 11 and one pachinko ball is fired at 48 pulses. When the operating lever 8 is released, the step motor (C) stops and the step motor 11 stops rotating. When the operation lever 8 is touched again, the timer 18 whose delay time is not specified in step (d) is activated, and then the process shifts to the loop of steps (b) and (a). Therefore, timer 1 only at the start of driving
8 operates and the time until the step motor 11 starts is unspecified. By setting the delay time to be equal to or shorter than 0.6 seconds, which is a shot firing cycle, normally, shots can be shot with almost no discomfort.

In the above embodiments, the step motor is used as the power source. However, the same applies to the case where a synchronous motor is used or an electric actuator such as a rotary solenoid or a direct acting solenoid is used. By providing a timer in, the time until it starts can be made unspecified. Further, it is needless to say that the present invention can be applied to a pachinko ball launching device configured such that an electric actuator is started by a micro switch or another switch instead of the touch detection circuit 17.

[0014]

As described above, in the pachinko ball launching apparatus according to the present invention, the time from the touch of the operating lever to the start of the electric actuator is made unspecified.
Since it is not possible to finely adjust the timing of pachinko ball firing, it makes no sense for the player to use an electronic metronome, etc., so that a fair service can be provided to the player. There is.
