Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses magnets in pachinko machines to make it possible to win prize balls by guiding them to number 1, thereby fraudulently obtaining prize balls, and to fraudulently obtain prize balls by opening the glass door unnecessarily. Prevent fraudulent activities such as getting prize balls! )
The second device is related to one.

[Problems with conventional techniques] One of the ways to improve pachinko machines is to place a powerful magnet 1 in front of a glass door to guide the ball to the winning ITI.

Therefore, there has been a demand for effective prevention and control measures against such fraudulent acts.

On the other hand, if there is a locking device on the glass door that covers the front of the pachinko machine (J'9), and a ball 11 marries on the pachinko board, the clerk will call 6E. l] The glass door is opened for processing. However, in the past, players have never been found at store I-1 using a duplicate key17).
l; Open the sea urchin glass door and go to the number 11 near the prize hole. ! ;
Illegal acquisition of prize balls by spreading 4, etc. is a bad thing.
I also do a lot of r acts, so it's only... 1+ +7. There is a strong need for preventive measures.

[L1 point of the invention] Therefore, the first point of the present invention is to detect fraudulent acts using magnets such as 1.1.1 and fraudulent acts using duplicate keys at an early stage to prevent damage. Defense+l t.

[Means for achieving the object] In order to achieve the object, the present invention provides a first reed switch that is turned on by detecting magnetic force near the winning opening of the game board 1-, and also opens the glass door. Install a microswitch that turns on when the first reed switch and the microswitch are connected in parallel to the self-holding circuit of the relay, and connect the relay contact that turns off when the relay is self-holding to the power supply circuit of the ball-launching motor. An object of the present invention is to provide an anti-tampering device for a Pachinko machine, characterized in that a second reed switch for releasing the self-holding of the relay is provided in an opening of a glass door.

[Function] No. 1: When the reed switch detects magnetic force or the glass door is opened, the relay is self-held and the batted ball firing motor stops, and this state will not be released unless the second reed switch is activated.

[Example] In the figure, 1 is the main body of the pachinko machine, 2 is the front frame, and 3 is the main body of the pachinko machine.
1 is a game board, 4 is a metal glass door fitted with glass that covers the front surface of the game board 3, and the - side is pivoted to the periphery of a window hole in the front frame 2 so as to be freely openable and closable. Reference numeral 5 denotes a cylinder lock of a glass door locking device provided on the opening side of the glass door 4, so that when a predetermined key is inserted from the front and rotated, the glass 4 is opened. A winning opening 6 is provided on the front of the game board 31)
Re.

A first reed switch 7, which operates mainly by detecting magnetic force, is provided on the back side of the game board 3 near the input fj D 6.

Reference numeral 8 denotes a microswitch attached to the game board 3, located in the space between the inner side edge of the glass door 4 and the game board 3 on the pivoting side of the glass door 4. Turns on when 4 is released. Fig. 3 shows the electrical circuit of this device, where 9 is a switch that is turned on by operating a ball-launching handle 10 protruding from the lower side edge of the front of the pachinko machine, and 11 is the ball-launching motor. be.

Reference numeral 12 denotes an indicator lamp provided on the front upper curtain plate of the pachinko machine. Therefore, 13 is a rectifier bridge circuit,
On the secondary side, a self-holding relay 14 and a self-holding release relay 15 are provided in parallel. On the other hand! No 1
In the self-holding circuit 4, a relay contact 16 that is turned on by excitation of the relay 14 is connected in parallel with the first reed switch 7 and the microswitch 8.
connected in series with the circuit.

17 is a second reed switch for self-hold release connected in series with the other relay 15, and the second reed switch is located at a position away from the first reed switch 7 on the back side of the game board 3 It is provided at a location away from the winning prize 10, and when this second reed switch 17 is turned on and the relay 15 is energized, the normally closed relay contact 18 connected in series with the relay 14 is turned off and the self-holding of the relay 14 is released. be done. Note that 19 is a normally open relay contact that is connected in series to the power supply circuit of the indicator lamp 12 and is turned on by excitation of the relay 14;
is a normally closed relay contact that is connected in series to the power supply circuit of the batted ball ejecting motor 11 and is turned off when the relay 14 is energized. Further, as shown in FIG. 4, a normally open relay contact 21 which is turned on by excitation of the relay 14 is provided in the power circuit of the alarm buzzer 22 and the in-store announcement device 23. For example, this announcement device may say, ``The anti-fraud device is currently operating -4~''. ...Please check the store.

'' on a tape recorder or voice synthesizer LS.
A predetermined announcement is pre-recorded in the I, etc., and when the power is turned on, a predetermined announcement is automatically broadcast into the store at the same time as an alarm buzzer sounds.

In the pachinko machine fraud prevention device configured in this way,
When an unauthorized player brings a magnet close to the winning hole 6, the first reed switch 7 is turned on and January No. 12 is excited. For this reason, the ball firing motor 11 is stopped and ball firing is disabled, and at the same time the display lamp 12 is turned on, the alarm buzzer 22 is sounded, and a predetermined message is broadcast in the store to prevent fraudulent activity. .

Also, when the glass door 4 is opened, the micro switch 8
is turned on and the relay 14 is similarly excited. The excitation of the relay 12 is not released even if the glass door 4 is gradually closed because its self-holding circuit is activated. To release the self-holding of January No. 14, it is necessary to bring a magnet (not shown) close to the surface of the game board 3 where the second reed switch 17 is hidden and turn on the second reed switch 17 with its magnetic force. There is. When this happens, the relay 15 closes the 1lit of the excited IJ and the 18th contact 18 is turned off, so the self-holding of the IJ 14 is released. In other words, when the glass door 4 is opened by a +F clerk, the magnet can be moved close to a predetermined position on the game board 4 after opening the glass door 4, and the magnet can be immediately removed. /-Ill's self-hold is released, but if it is due to an unauthorized releaser, 2nd Li-1~Switch 1
Since he did not know the procedure for releasing self-holding according to 7, he was unable to continue the game because the display lamp 12 continued to light up every time the glass door was opened, and at the same time the batted ball launch motor 11 did not rotate, making it easy to discover the illegal action. can.

[Effects of the Invention] As explained in 1-1, the present invention prevents the self-retention of unauthorized display from being released unless the second reed switch is activated, thereby preventing fraud using a magnet and duplicate keys. This has the effect of preventing unauthorized opening of the glass door. In addition, since it is composed of a simple circuit, it can be installed at low cost and fraud can be effectively prevented, which is extremely important for pachinko parlors.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention; Fig. 1 is a front view of a pachinko machine, Fig. 2 is a partial sectional view of the pachinko machine, and Figs. 3 and 4 are electrical circuits. It is a diagram.
