DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball firing drive control device for adjusting a ball jump amount of a pachinko machine.

[0002]

2. Description of the Related Art Heretofore, in a pachinko ball firing drive control device for a solenoid, there has been a method of controlling a constant current value applied to a solenoid as a method of controlling a ball jump amount. FIG. 6 is an electric circuit diagram of one embodiment of the present invention. The rising curve of the current of an electric component having an inductance such as a solenoid is an exponential function as shown in FIG. In this constant current control method at a constant current value, the current values are represented by C ₁ , C ₂ , C
Method of controlling the current applied to the solenoid is generally performed by ₃ as variable.

[0003]

SUMMARY OF THE INVENTION In a method for controlling the ball jump amount in the force generated by a solenoid, the ball jump amount is controlled stably with respect to fluctuation factors such as a change in input voltage, a temperature change, and a temperature rise in energization. As a method, the current control method is the best method. However, in such a constant current control method, as shown in FIG. 9, the operation of the movable portion of the solenoid is completed before the current is stabilized from the rising state, and the current control is performed. There is no time to be done. As shown in FIG. 10, even in a control system controlled to a constant current D, if the input power supply voltage fluctuates, the current actually flowing through the solenoid becomes zero.
−D ₁ ′ -D ₁ , 0-D ₂ ′ -D ₂ , 0-D ₃ ′ -D ₃
It varies as shown in the later than the time t ₃ is controlled to be constant. In the ball launching device in the solenoid, it is necessary to control the flying of the ball while the movable part of the solenoid is actually operating, but as shown in FIG. There is a problem that the current control in the constant current control at a constant current is very early, and the amount of ball jump greatly changes due to the rising characteristic before the current becomes constant.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to control the flying distance of a ball by controlling only a current rising curve input to a solenoid of a firing rod driving device. It is characterized by the following.

[0005]

FIG. 1 is an electric circuit diagram of a first embodiment of the present invention. When the solenoid signal is turned on, the transistor TR
1 is turned off, it is charged through the resistor R ₁ to the capacitor C ₁ by the voltage of the point a 'of the charging curve forming circuit, FIG. 2
Thus, a characteristic for controlling the current flowing through the solenoid 4 can be obtained. 2 is a comparator and 3 is a fine adjustment volume. In the ball jump amount adjustment, the voltage V of a 'of the charge curve forming circuit is changed by the volume 5, and the current flowing through the solenoid 4 is controlled as shown in FIG. Figure 4 is a second embodiment of the present invention, and controls the charging current to the capacitor C ₂ by a change in volume 7. In each of the embodiments of the present invention described above, the charge characteristic of the capacitor is used to control the rise characteristic of the current of the solenoid, but a circuit for generating any other function curve may be used. Also, jump adjustment volume,
The position of the fine adjustment volume is also an example, and any other method may be used as long as it controls the current rise characteristics of the solenoid.

[0006]

According to the present invention, the flying amount of the ball is controlled by controlling only the current rising curve input to the solenoid of the firing rod driving device. Therefore, the current during operation is controlled. In order to stably control the flying force, a good and inexpensive system can be made with a general solenoid. Since only the rising curve of the current needs to be controlled, energy-efficient control can be performed.
