Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention provides an operation unit which can be operated by a player on the front of a front frame of a pachinko machine, and an antenna of an electronic touch switch provided on the operation unit by the player. The present invention relates to an electric pachinko machine that fires a hit ball by operating an electric drive source such as a motor or a solenoid by contacting a tip portion.

(Prior art) In a conventional electric pachinko machine, a micro switch (main switch) for opening / closing a power supply is closed by rotating an operation unit arranged on a front face of a front frame of the pachinko machine, and a motor, a solenoid, etc. An electric drive source is driven, and the hammer arm is repeatedly operated by the electric drive source to fire a hit ball. However, in such an electric pachinko machine, the electric drive source is driven simply by rotating the operation unit, so the operation unit is fixed at a fixed rotation position with a matchstick or coin, etc., and one person occupies multiple pachinko machines There is a problem that illegal games such as playing can be easily performed. For this reason, recently, an electronic touch switch antenna tip is provided on the operation unit for the purpose of preventing the above-mentioned illegal game action, and the player touches the electronic touch switch antenna tip to operate the operation unit. A structure in which a microswitch and an electronic touch switch are used in combination so that an electric drive source is driven only by rotating the switch is adopted.

FIG. 6 is a circuit diagram showing a conventional example of the above-described electric pachinko machine (see, for example, Japanese Utility Model Publication No. 55-46197 and Japanese Patent Publication No. 58-49270). This electric pachinko machine is
The micro switch 101 is connected in series to the power supply circuit of the electronic touch switch 100, and the player rotates the operation unit while touching the antenna tip 102 of the electronic touch switch 100 provided on the operation unit, and the micro switch 101 is connected to the micro switch 101. When the switch 101 is closed, the electric drive source 103 is driven.

FIG. 7 is a circuit diagram showing another embodiment of the electric pachinko machine described above (see, for example, Japanese Patent Publication No. 58-8272). This conventional example uses an electronic touch switch 10
0 antenna tip 102 and micro switch 101 are provided,
The micro switch 101 is connected in series between the electronic touch switch 100 and the electric drive source 103, and the player operates while touching the antenna tip 102 of the electronic touch switch 100 provided on the operation unit. When the micro switch 101 is closed by rotating the unit, the electric drive source 103 is driven.

(Problems to be Solved by the Invention) By the way, the above-mentioned conventional electric pachinko machine is so wide that it is possible to launch a hit ball or perform a single shot by opening and closing the electrolytic circuit of the electric drive source 103. Since a large current required for driving the electric drive source 103 must be intermittent, a relatively expensive power switch such as a micro switch must be used so as not to cause a contact failure. Was. A power on / off switch such as a micro switch used in a conventional electric pachinko machine has a problem that its service life is short because it repeatedly switches on and off a large current.

The present invention has been made in view of the above problems,
The purpose is to enable the power supply circuit of the electric drive source to be opened and closed without using a relatively expensive power supply on / off switch such as a microswitch, and to reduce the cost and to prevent the occurrence of contact failure. Such an electric pachinko machine is provided.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an electronic touch switch with an antenna tip portion provided on the front surface of a front frame of a pachinko machine and capable of turning operation by a player. Forming
An electric pachinko machine in which an electric drive source is activated to fire a hit ball when a player touches the tip of the antenna, an electronic touch switch body and an antenna of an electronic touch switch provided on an operation unit. A contact for opening and closing the antenna circuit is provided in an antenna circuit for electrically connecting the distal end portion, and the contact is opened and closed in connection with a rotation operation of the operation unit. .

(Operation) Since only a weak current flows in the antenna electric path for electrically connecting the electronic touch switch and the tip of the antenna of the electronic touch switch provided on the operation unit, and poor contact hardly occurs, relatively inexpensive electricity is used. In addition to being able to use contacts,
The service life can be extended.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. First
The figure is a perspective view of the launching device portion of the electric pachinko machine.
In the figure, reference numeral 1 denotes a front frame 2 of the pachinko machine (see FIG. 2).
The mounting plate 3 fixed to the rear surface of the mounting plate 1 is a hammer arm rotatably supported by a shaft 4 on the rear surface of a substantially central portion of the mounting plate 1. An arm 5 is fixed to the hammer arm 3, and the arm 5
Has a roller 6 at the tip. Reference numeral 7 denotes a motor as an electric drive source, and a cam 9 fixed to a motor shaft 8 of the motor.
Engage with the roller 6 to repeatedly drive the hammer arm 3. Reference numeral 10 denotes a rotation shaft of an operation lever 19 described later, and a pulley 11 is fixed to a rear end thereof. Reference numeral 12 denotes a spring adjuster. The other end of a coil spring 13 having one end connected to the hammer arm 3 and the other end of a wire 14 having one end connected to the pulley 11 are connected. The power can be adjusted freely.

Reference numeral 16 denotes an operation unit. In this embodiment, an operation lever 19 is rotatable between a rear grip unit 17 fixed to the front surface of the front frame 2 and a front grip unit 18 fixedly connected thereto. Is provided. The operating lever 19 is provided integrally with a rotating shaft 10 at the center. The rotating shaft 10 is inserted through the center of the rear grip portion 17 and protrudes toward the front side of the mounting plate 1, and the pulley 11 is fixed to the protruding portion. . Therefore, when the player rotates the operation lever 19, the pulley 11 rotates, whereby the wire 14 is pulled and the tensile force of the coil spring 13 is increased, and the resilience of the hit ball is increased by the degree of rotation of the operation lever 19. Adjusted freely.

The operation lever 19 is provided with conductivity by chrome plating the surface, and the rotating shaft 10 integral therewith is made of a highly conductive metal material and is always electrically conductive with the surface of the operation lever 19. ing. 20 is an electronic touch switch body provided on the back side of the front frame 2, 21 is its antenna line, 22, 2
2 is a power terminal of the electronic touch switch body 20, 23, 23
Is a wiring for supplying operating power to the motor 7 from a control contact of the electronic touch switch body 20. Note that the entire operation lever 19 serves as an antenna tip of the electronic touch switch body 20.

Thus, in the present invention, the rotation shaft 10 of the operation lever 19 is
A defective conductive portion 24 is provided on the outer periphery of the rear end portion with an electrically insulating material such as plastic. Further, a fixing base 25 is formed on the mounting plate 1, and the electric brush 26 is fixed to the fixing base 25. Then, the front end of the electric brush 26 is resiliently contacted with the outer periphery of the rear end of the rotary shaft 10, and the antenna wire 21 of the electronic touch switch body 20 is connected to the electric brush 26, whereby the operation lever 19 is rotated to rotate the antenna. Provide contacts for opening and closing the electric circuit. Note that the electric brush 26 is in contact with the defective conductive portion 24 when the operation lever 19 is in the non-rotation state, and the antenna wire 21 is placed in a non-conduction state with the rotating shaft 10.
The position is selected so that when 19 rotates, it is separated from the defective conductive portion 24 and becomes conductive.

Next, the operation of the present invention will be described with reference to the circuit diagram shown in FIG. 4. When the player holds the operating lever 19, the tip of the electric brush 26 is in contact with the defective conductive portion 24 and the antenna Since the electric circuit contacts are in a non-conductive state, the electronic touch switch body 20 does not operate and the motor 7 is kept stopped. Then, when the player rotates the operation lever 19, the tip of the electric brush 26 is disengaged from the defective conductive portion 24 and conducts to the rotating shaft 10, and further conducts to the operation lever 19 to close the antenna electric path, so that the electronic touch is performed. The switch body 20 is operated, the motor 7 is started, and a hit ball is fired.

In the above embodiment, the defective conductive portion 24 is buried in the rotary shaft 10. However, as shown in FIG. 3, a plastic annular insulating cap 27 is provided as the defective conductive portion 24 at the rear end of the rotary shaft 10. You may make it fit in.

FIG. 5 shows that a normally closed microswitch 28 (for single-shot operation) is provided in the rear grip portion 17 of the operation portion 16. The player pushes the push button 29 while gripping the operation lever 19. The micro switch 28 is connected to the rotating shaft 10 and the other terminal is connected to the operation lever 19, while allowing the user to perform a pressing operation. In the case of this embodiment, an insulator 30 is interposed between the operation lever 19 and the rotating shaft 10 to integrate them. By providing the micro switch 28 in the operation unit 16 in this manner, if the micro switch 28 is pushed through the push button 29 while the operation lever 19 is held, the electronic touch switch body 20 does not operate. The motor 7 can be driven intermittently even while the operation lever 19 is kept rotating, so that a so-called single shot can be fired.

(Effects of the Invention) As described above, according to the present invention, a contact is provided in an antenna electric path for electrically connecting an electronic touch switch main body and an antenna tip of the electronic touch switch main body provided in an operation unit. Since the power supply circuit of the motor is indirectly opened and closed by opening and closing the contacts in connection with the rotation operation of the operation unit, only a weak current flows in the antenna electric circuit, so that it is used as an electric contact. Even if an inexpensive one is used, it is very economical without causing a contact failure or damaging the contact in a short period of time.

When a switch for single hitting is provided in the operation unit as in the embodiment, the switch can be easily mounted without requiring complicated wiring.
