Abstract

PURPOSE:To provide a ball hitting device in an energy-saving type pachinko game machine, for which a rotary solenoid is used as a driving power supply, and in which the application of an electric current to the rotary solenoid is cut off simultaneously with the end of a hammer's hitting a ball so that no wasteful consumption of electric energy may take place. CONSTITUTION:In a ball hitting device for which a rotary solenoid is used as a driving power supply, a sensor 9 for detecting that a hammer reaches a ball hitting position is arranged and according to a signal from the sensor 9, the application of an electric current to the rotary solenoid is cut off.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball striking device for a pachinko machine using a rotary solenoid as a drive source.

[0002]

2. Description of the Related Art Conventionally, in a pachinko machine using a rotary solenoid as a drive source, the pulse width applied to the rotary solenoid has been constant. However, the speed of the mallet is not constant because of flight adjustment, and the time required from energization to the end of the ball is different. The pulse width was set to be slightly larger than the required maximum time because the mallet always energizes the ball at the end of hitting.

[0003]

However, in the above-mentioned conventional technique, since the rotary solenoid is energized even after the ball is hit, there is a problem in that the electric energy is wasted accordingly. The present invention aims to solve the above problems.

[0004]

In order to achieve the above object, the present invention provides a ball hitting device using a rotary solenoid as a driving source, which is provided with a sensor for sensing that a mallet has hit a ball hitting position. It is characterized in that the electric power to the rotary solenoid is cut off by the signal from the sensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail with reference to FIGS. A hitting unit 1 has a rotary solenoid 3 arranged on a substrate 2 and a mallet 5 fixed to a rotary shaft 4 thereof. 6 is an upper stopper, 7 is a lower stopper,
Reference numeral 8 is a touch switch. Reference numeral 9 is an optical sensor for detecting that the mallet 5 has reached the hitting position where it abuts against the upper stopper 6.

Next, the operation will be described. When a pulse of a certain width is applied to the rotary solenoid 3, the mallet 5 rotates upward and comes into contact with the upper stopper 6 to finish the hitting. The optical sensor 9 indicates that the mallet 5 has reached the hitting end position.
Is detected, the detection signal is transmitted to the control circuit of FIG. 2, and the pulse applied to the rotary solenoid 3 is instantly turned off. Therefore, the rotary solenoid 3
The current is cut off at the same time when the ball is hit, and no unnecessary current flows. The sensor may be a micro switch, a pressure sensitive switch such as a stopper, or any other sensor capable of sensing that the mallet has reached the hitting end position.

[0007]

According to the present invention, in a ball striking device using a rotary solenoid as a driving source, a sensor for detecting that the mallet has hit the ball is disposed, and a signal from the sensor is used to send a signal to the rotary solenoid. Since the energization is cut off, the hammer is rotated and hit with a pulse of a certain width, and even if there is unevenness in the speed and time at which the mallet reaches the hitting end position, the rotary solenoid is always turned off at the same time as the hitting.
It is possible to provide a ball striking device in an energy-saving type pachinko machine without wasting electric energy.
