Abstract

PURPOSE:To enable an illegal ball to be easily detected, and prevent the occurrence of a trouble with a player by selecting a pachinko ball molded of a non- magnetic material for killing a ball projection, regarding an electric pachinko game machine where a ball is hit and projected with an electric hammer. CONSTITUTION:In an electric pachinko game machine, a hammer 5 is electrically caused to reciprocate for hitting and projecting a pachinko ball on a projection rail 4, and a solenoid 30 is actuated synchronously with the reciprocating motion of the hammer 5 for feeding balls one by one to the rail 4. In this pachinko game machine, an electric proximity switch 29 is provided at the intermediate position of a ball feed passage 28 continuous from a ball tray 22 to the rail 4 for detecting whether a ball is a magnetic body or a non-magnetic body. Constitution is so made that a magnetic body signal detected with the switch 29 is a prerequisite for actuating the solenoid 30.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric pachinko machine for striking and launching a pachinko ball with an electric mallet, and more particularly to an electric pachinko ball formed of a non-magnetic material for selecting a pachinko ball from being ejected. The present invention relates to a hitting ball feeding device for a pachinko machine.

[0002]

2. Description of the Related Art Steel balls, stainless steel balls, brass balls, high manganese balls, etc. have heretofore been used as pachinko balls. Among them, the above-mentioned stainless steel balls, brass balls, high manganese balls, etc. are non-magnetic materials and are not attracted to the magnets, so they have been used conventionally from the viewpoint of preventing fraudulent acts using the magnets.

By the way, a proximity switch is now widely used as a means for detecting passage of a winning ball or the like in a pachinko machine. Therefore, at present, steel balls that can react to the proximity switch are exclusively used. It has come to be used.

[0004]

However, not only steel balls but also non-magnetic high-manganese spheres which have been conventionally used are mixed in a large number of pachinko balls used in a pachinko game hall. Occasionally, a non-magnetic ball was illegally used by a player from another playground.

In such a case, even though the pachinko ball hit by the player enters a specific winning opening, the proximity switch does not react and the prize ball may not be released. There was a problem that caused trouble with the player.

DISCLOSURE OF THE INVENTION The hitting ball feeding device for an electric pachinko machine of the present invention is intended to solve the above-mentioned problems, in which a mallet is electrically reciprocated to strike a pachinko ball on a launch rail. In an electric pachinko machine that operates a solenoid in synchronism with the reciprocating motion to send one pachinko ball to the launch rail, the pachinko ball is connected to the launch rail from the ball saucer to the launch rail. An electromagnetic proximity switch for detecting whether the pachinko ball is a magnetic substance or a non-magnetic substance is provided, and the magnetic substance detection signal from the proximity switch is a requirement for operating the solenoid. It is what

[0007]

Since the solenoid does not operate and the pachinko ball is not fed to the launch rail unless there is a magnetic substance detection signal from the proximity switch, firing of the non-magnetic ball is prevented and no trouble occurs.

Reference numeral 15 denotes a motor in which a cam 17 is fixed to a rotary shaft 16, and the rotary shaft 16 can be engaged with an engagement roller 19 of an engagement arm 18 provided integrally with the mallet 5. Therefore, when the motor 15 is rotationally driven and the cam 17 is rotated, the mallet 5 reciprocates via the engagement roller 19 and the engagement arm 18 so that the hit ball on the launch rail 4 can be hit and shot.

Reference numeral 20 denotes an optical sensor including a light projector and a light receiver. When the mallet 5 stops at the position shown by the solid line in FIG. 2, the other end of the mallet 5 is detected by the optical sensor 20.

On the other hand, 21 denotes a front opening / closing plate having the ball receiving tray 22 formed on the front surface thereof, and 23 denotes a payout opening for paying out prize balls to the ball receiving tray 22. 24 is a glass frame. Front opening and closing plate 2
On the inner surface of 1, there is provided a feeding device 26 for sending one pachinko ball stored on the ball receiving tray 22 to the launch rail 4 from the ball sending port 25.

As shown in FIG. 4, the feeding device 26 is provided with a feed port 27 communicating with the ball receiving tray 22 and a vertical feed path 28 communicating with the ball feeding port 25. 28
An electromagnetic proximity switch 29 is provided on the upper side, and an operating mechanism 31 operated by a solenoid 30 is provided outside one side of the feeding path 28. The operating mechanism 31 includes an operating lever 33 pivotally supported by a support shaft 32 and an operating lever 35 pivotally supported by a support shaft 34.
The operating lever 35 and the operating lever 35 can cooperate with each other by loosely fitting a pin 37 formed in the operating lever 35 into a long hole 36 formed in the operating lever 33. Indicates that the other end of the actuating lever 33 is retracted from the feeding path 28 when it has advanced into the feeding path 28 as indicated by the solid line.

An operation arm supported so as to be swingable in a seesaw shape, a distal end of the operation arm 38 is loosely fitted in an engagement hole 42 of the operation lever 33, and a coil spring 41 is moored at the other end. Due to elasticity, the tip of the actuating lever 33 is urged so that the tip of the actuating lever 35 retracts from the ball sending port 25 and the tip of the actuating lever 35 advances to the ball sending port 25.

Therefore, when the solenoid 30 is not excited, the pachinko ball B flowing down the ball-sending port 25 due to the tip of the operating lever 35 advancing to the ball-sending port 25 as shown by the solid line is moved by the operating lever 35. The pachinko ball B is temporarily stopped and detected by the electromagnetic proximity switch 29. When the solenoid 30 is excited, the operating arm 3
Since 8 is sucked and the escapement 35 is retracted, the actuation lever 33 is advanced at the same time. Then, the pachinko ball B is delivered to the launch rail 4 from the ball delivery port 25.

As shown in the drawing, the signal of the light receiving portion of the optical sensor 20 is input to the NAND gate 45 through the amplifying transistor 43 and the signal of the electromagnetic proximity switch 29, and the output of the NAND gate 45 is input to the NAND gate 45. It is connected to the drive Darlington connection transistor 46 of the solenoid 30 via 47.

Therefore, when the optical sensor 20 detects the other end of the mallet 5 and the electromagnetic proximity switch 29 detects the presence of a pachinko ball, the NAND gate 45 operates to switch and excite the solenoid 30. In other words, solenoid 30
In order to operate the,
This is when the both requirements for the magnetic substance to be detected by 9 are satisfied.

In the hitting ball feeding device of the electric pachinko machine constructed as described above, when the player rotates the handle 1, the motor 15 operates to rotate the cam 17 and reciprocate the mallet 5. When the magnetic proximity switch 29 detects the magnetic pachinko ball B, the solenoid 30 is excited each time the other end of the mallet 5 is detected by the optical sensor 20, and the operation arm 31 is attracted to the operation mechanism 31. Activates and sends one pachinko ball B to the launch rail 4 addressed to one.

When a non-magnetic pachinko ball B is sent from the ball tray 22, the electromagnetic proximity switch 29 is used.
Does not operate, the solenoid 30 does not operate even if the optical sensor 20 operates, and the pachinko ball B stops there without being sent to the firing rail 4. Therefore, the non-magnetic sphere is not fired.
