Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement of a ball hitting device in an electric pachinko machine, and its purpose is to adjust the launching force of the ball hitting device without using electrical adjustment parts. The purpose is to reduce the occurrence of failures and operate smoothly and efficiently using a simple mechanical structure.

[Subject skill]

Conventionally known ball hitting devices for pachinko machines include:
There are manual types and electric types that use an electric motor, but in recent years electric types have become the majority. However, in the case of an electric type, many parts are used to drive the batting rod that shoots pachinko balls, such as an electric motor, cam, and gears, so the structure is not only complicated, but also the cam and gears. There were many cases where gears were damaged or broken. In addition, when firing a pachinko ball, the operator turned the operating handle to turn on a switch that energized the electric motor, and at the same time pulled the blade to adjust the firing force, so operating the operating handle required considerable force. As a result, users' wrists could become fatigued after playing for long periods of time. Moreover, due to wrist fatigue, etc., it becomes difficult to hold the operating handle in a fixed position against the force of the spring, and as a result, even if you intend to maintain a constant firing force, the firing force becomes distorted, and the user Pachinko balls could not be fired continuously as desired, resulting in unfavorable reviews from users.

For this reason, recently, instead of the electric motor mentioned above, a rotary solenoid is used, and the batting rod is attached to the rotor shaft so that it can be directly rotated, so that the launching force of the pachinko ball can be adjusted as desired by the user. A ball hitting device for pachinko balls has been put into practical use.

[Problems to be Solved by the Invention] The above-mentioned ball hitting device using a rotary solenoid can vary the launching force of a pachinko ball at any time by varying the excitation force of the solenoid, and can vary the current flowing through the solenoid. Although it has the advantage of being able to control the intermittent time and freely adjust the number of shots within the legally specified range (0 to '007 minutes), when adjusting the firing force of the pachinko ball, -C The current supplied to the rotary solenoid is adjusted by controlling the strength of the current supplied to the rotary solenoid by operating the operating handle, and the adjustment means used is, for example, a current control component such as a variable resistor. Failures such as poor contact and burnout are likely to occur, and
Electrical parts such as resistors are required for each pachinko machine, so the amount of power required for each pachinko machine is large, and voltage fluctuations due to power loss or temperature changes in variable resistors can cause the current flowing through the solenoid to decrease. There was a problem in that the firing force varied slightly, making it difficult to maintain a constant firing force, and the user had to constantly make fine adjustments to the operating handle.

The present invention addresses the above-mentioned problems and has developed an electric motor that allows the user to arbitrarily and easily adjust the firing force of pachinko balls in a ball hitting device using a simple mechanical adjustment mechanism without using any electrical parts. The purpose of the present invention is to provide a ball hitting device for pachinko.

[Means to solve the problem]

In the present invention, a rotary solenoid is integrally provided on one side of the mounting board, and a ball-striking rod is attached to the rotor shaft of the solenoid that protrudes from the other side of the mounting board. An arcuate starting position setting frame body that sets the starting position (starting point) of the rod within the range of the rotation angle of the batting rod engages with teeth carved inside the arc-shaped part of this setting frame body. A starting position setting device for the batting rod consisting of a spur gear that rotates the setting frame body by a predetermined angle is provided, and this starting position setting device is driven and adjusted by an operation handle provided on the pachinko machine to set the starting position of the batting rod. It is characterized by being configured so that the starting position can be adjusted.

[Function] When adjusting the firing force of a pachinko ball, the present invention drives a spur gear by rotating an operating handle, and rotates an arcuate starting position setting frame that meshes with the spur gear by a predetermined angle. The starting position of the ball rod can be set to a position where a pachinko ball can be hit and fired with a desired firing force, and the adjustment range of firing force can be set almost the same for each pachinko machine, allowing users to The present invention is characterized in that no matter which pachinko machine is used, the launching force of pachinko balls can be arbitrarily adjusted by a ball launcher position setting device having a simple mechanical structure.
