Description

[Detailed description of the invention]

(Industrial Application Field) The present invention provides an operation section that can be operated by a player on the front surface of the front frame of a pachinko machine, and when the player touches the contact section of a touch switch provided on the operation section, the motor and solenoid are activated. This invention relates to an electric pachinko machine that fires balls by operating an electric power source such as the above. (Prior art) In conventional electric pachinko machines, by rotating the operating unit installed on the front frame of the pachinko machine, the micro-sinch for opening and closing the power supply is closed, and the electrical power of the motor, solenoid, etc. A driving source was driven, and the hammer arm was repeatedly operated by the electric driving source to fire the ball. However, in such electric pachinko machines, the electric drive source is driven simply by rotating the operation unit, so the operation unit is fixed at a constant rotational position with a matchstick or coin, and multiple pachinko machines can be operated by a person. There was a problem in that illegal games such as possession could easily be carried out. For this reason, recently, in order to prevent the above-mentioned fraudulent gaming activities, a touch switch contact part is provided on the operation part, and the player rotates the operation part while touching the touch switch contact part. Deji 7
Figure 6 shows a circuit diagram of a conventional electric pachinko machine as described above. (For example, see Japanese Utility Model Publication No. 55-46197 and Japanese Patent Publication No. 58-49270).
When the player touches the contact part 102 of the touch switch 100 provided on the operation part and rotates the operation part to close the microswitch]01, the electric drive source 103 is driven. is being used. Furthermore, FIG. 7 is a circuit diagram showing another conventional example of the electric pachinko machine as described above (eg.
(See Publication No. 72). In this conventional example, a contact part 102 of a touch switch 100 and a microswitch 101 are provided in an operation part, and the microswitch 101 is connected to the touch switch 100.
The microswitch 10 is connected in series between the microswitch 100 and the electric drive source 103, and when the player touches the contact portion 102 of the touch switch 100 provided on the operation section and rotates the operation section, the microswitch 10 is closed. At this time, the electric drive source 103 is activated immediately. (Problems to be Solved by the Invention) By the way, the above-mentioned conventional electric pachinko machine is designed to enable firing of balls and single shots by opening and closing the power supply circuit of the electric drive source 103. Since the large current required to drive the 03 must be intermittent, it is necessary to use a relatively expensive power switch such as a microswitch to prevent contact failure. did not become. and,
The power on/off switches, such as microswitches, used in conventional electric pachinko machines have the problem of short service life because they repeatedly turn on and off large currents. The present invention is an attempt to solve the above problems, and is an attempt to solve the above problems by providing an optical system installed on the front frame of a pachinko machine.

[And in an electric pachinko machine, a touch switch contact part is formed on the operation part that can be operated by a player, and when the player touches the contact part, an electric drive source is activated to fire a batted ball, An electric contact is provided in an electric path that electrically connects the touch switch and a contact portion of the touch switch provided on the operation section to open and close the electric circuit in relation to the operation of the operation section. It is something. (Function) Only a weak current flows in the electrical path that electrically connects the touch switch and the contact part of the touch switch provided on the operation unit, and the contact resistance may be large, so relatively inexpensive electrical contacts can be used. In addition to this, it is possible to extend the service life. (Example) Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a firing device portion of an electric pachinko machine. In the figure, 1 is a mounting plate fixed to the back of the front frame 2 (see Figure 2) of the pachinko machine, and 3 is a hammer arm rotatably supported by a shaft 4 on the rear surface of the approximately central part of the mounting plate 1. An arm 5 is fixed to the hammer arm 3, and a roller 6 is provided at the tip of the arm 5. 7 is a motor as an electric drive source, and a cam 9 is fixed to the motor shaft 8 of this motor.

Reference numeral 10 denotes a rotation shaft of an operating lever 19, which will be described later, and a pulley 11 is fixed to the rear end thereof. 12 A coil spring 13 with one end connected to the mallet arm 3 with a spring adjuster.
A wire 14 whose one end is connected to the pulley 11 is connected to the other end thereof, and the initial elastic force of the coil spring 13 can be freely adjusted by rotating the diamonds 1 to 15. Reference numeral 16 denotes an operating section, in which an operating lever 19 is freely rotatable between a rear grip section 17 fixed to the front surface of the front frame 2 in this embodiment and a front grip section 18 fixedly connected thereto. It is set up and configured. The operating lever 19 is integrally provided with a rotating shaft 10 at its center, and the rotating shaft 10 is inserted through the center of the rear grip portion 17 and projects to the front side of the mounting plate, and the pulley 1 is fixed to the projecting portion. Ru. Therefore, when the player rotates the operating lever ]9, the pulley]1 rotates, thereby pulling the wire [1] and increasing the tensile force of the coil spring]3, depending on the degree of rotation of the operating lever]9. The rebound force of the ball can be freely adjusted. The operating lever 9 has a chrome-plated surface to make it conductive, and the rotating shaft 9 integrated therewith is made of a highly conductive metal material and is always electrically connected to the surface of the operating lever 19. conductive to. 20 is a touch switch provided on the back side of the front frame 2; 2] is its antenna wire; 22
．． 22 is the power terminal of this touch switch 2 (1), 23.
23 is a wiring for supplying operating power to the motor 7 from the control contact of the touch switch 2o. Note that the entire operation lever 19 serves as a contact portion of the touch switch 20. Therefore, in the present invention, the rotation shaft 1 of the operation lever ]9

By fixing them, an electric contact is provided which can be opened and closed by rotating the operating lever 19. Then, the antenna wire 2 of the touch switch 20 is connected to the electric brush 26. The electric brush 26 is in contact with the defective conductive portion 24 when the operating lever 19 is in a non-rotating state, and the antenna wire 2 is placed in a non-conducting state with the rotating shaft 10, and when the operating lever 19 is rotated, the defective conductive portion 24 is in contact with the electric brush 26. Conductive part 24
The location is chosen so that it is more disconnected and conductive. Next, the operation of the present invention will be explained with reference to the circuit diagram shown in FIG. Since the electrical contacts are in a non-conducting state, the touch switch 20
is not operated and the motor 7 is kept in a stopped state. Then, when the player rotates the operating lever 19, the electric brush 2
The tip of 6 comes off the defective 4 electric part 24 and is electrically connected to the rotating shaft 10, and further to the operating lever 19, so that the touch switch 20 is operated, the motor 7 is started, and the ball is fired. In the above embodiment, the defective conductive portion 24 is embedded in the rotating shaft ]0, but as shown in FIG. It may be fitted to the rear end. In addition, FIG. 5 shows a normally closed micro-sinch 28 provided in the rear grip section 7 of the operating section 16, which the player presses via the push button 29 while holding the operating lever 19. In addition to being operable, one terminal of the microswitch 28 is connected to the rotating shaft 10 and the other terminal is connected to the operating lever 19. In this embodiment, an insulator 30 is interposed between the operating lever 19 and the rotating shaft 10 to integrate them. By providing the microswitch 28 in the operating section 16 in this manner, if the microswitch 28 is pressed via the push button 29 while holding the operating lever 19, the touch switch 20 will not operate, so the operating lever Even if the motor 19 is kept rotating, the motor 7 can be operated intermittently, making it possible to fire the ball in a single shot. (Effects of the Invention) As described above, according to the present invention, an electric contact for opening and closing the power supply circuit of the motor is provided in the electric path between the touch switch and the contact part of the touch switch provided on the operation unit. Since only a weak current flows in the electrical circuit, even if inexpensive electrical contacts are used, they will not cause contact failure or damage in a short period of time, making it extremely economical. becomes. Incidentally, when the operating section is provided with a switch for single-shot operation as in the embodiment, it can be easily installed without requiring complicated wiring.
