Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for preventing a glass door of a pachinko machine from being opened unnecessarily and illegally obtaining prize balls.

[Conventional technology and its problems] Usually, a locking device is attached to the glass door that covers the front of the game board in a pachinko machine, and when a ball gets stuck on the game board, the clerk opens the glass door with a key. I am trying to process it accordingly. However, there have been many cases of malicious acts in which players use duplicate keys to open glass doors without being discovered by store staff, widen the spacing between the nails near the prize holes, etc., in order to fraudulently obtain prize balls. Measures to prevent these problems are strongly desired.

The glass door opening alarm device for pachinko machines disclosed in Japanese Patent Application Laid-Open No. 145654/1985 was designed to prevent the above-mentioned fraud.When the glass door is opened illegally, a buzzer sounds and the buzzer sounds. In order to stop the pachinko hall, the control switch in the control box installed in the prize exchange area, control room, etc. must be turned off. However, with such a configuration, even if the store clerk attempts to open the glass door for non-fraudulent purposes, the store clerk must operate the control switch each time before the buzzer sounds, making the work complicated. There was a problem.

[Object of the Invention] Therefore, the present invention aims to prevent fraud due to the use of a duplicate key without complicating the work as described above.

[Means for achieving the object] In order to achieve the object, the present invention provides a micro switch that is turned on when the glass door is opened in the self-holding circuit of the relay, and a relay contact that is turned on when the relay is self-holding. is provided in the power supply circuit of the glass door open indicator lamp, and a relay contact that is turned off when the relay is self-held is provided in the power supply circuit of the glass door open indicator lamp, and a relay contact that is turned off when the relay is self-held. An object of the present invention is to provide a device for preventing unauthorized opening of a glass door in a pachinko machine, characterized in that a reed switch for releasing the self-holding of the relay is provided in the opening of the glass door. It is something to do.

[Function] When the glass door is opened, the relay self-holds and the glass door open indicator lamp lights up, at the same time the batted ball firing motor stops, and this state will not be released unless the reed switch is activated.

[Example] In the figure, 1 is the pachinko machine main body, 2 is its front frame, 3 is a game board, 4 is a metal glass door fitted with glass that covers the front of the game board 3, and one side is the front frame of the front frame 2. It is pivoted to the periphery of the window hole so that it can be opened and closed. Reference numeral 5 denotes a cylinder lock of a glass door locking device provided on the open side of the glass door 4. When a predetermined key is inserted from the front and rotated, the glass door 4 is opened.

Figure 3 shows the electrical circuit of this device, and numeral 6 is located on the pivoting side of the glass door 4 in the space between the inner surface of the side edge of the glass door 4 and the game board 3, and is attached to the game board 3. A micro switch 6 is turned on when the glass door 4 is opened. Further, 7 is a switch that is turned on by operating a ball firing handle 8 protruding from one side edge of the lower front of the pachinko machine, and 9 is a ball firing motor. 10
is a glass door open indicator lamp installed on the upper front panel of a pachinko machine. Reference numeral 11 denotes a rectifying bridge circuit, and on its secondary side, a self-holding relay 12 and a self-holding release relay 13 are provided in parallel. In the self-holding circuit of one relay 12, a relay contact 14 which is turned on by excitation of the relay 12 is connected in parallel with the micro switch 6, and this is connected in series with the circuit of the relay 12. Reference numeral 15 denotes a reed switch for self-hold release that is connected in series with the other relay 13. This reed switch is provided on the back side of the game board 3, and when the reed switch 15 is turned on, the relay 13 is turned on.
When energized, the normally closed relay contact 16 connected in series with the relay 12 is turned off, and the self-holding of the relay 12 is released. Note that 17 is a normally closed relay contact that is connected in series to the power circuit of the glass door open indicator lamp 10 and turns on when the relay 12 is energized; It is a normally closed relay contact that is turned off by

In the unauthorized opening prevention device configured in this way,
When the glass door 4 is opened, the micro switch 6 is turned on, the relay 12 is energized, and the door open indicator lamp 1 is activated.
At the same time that 0 lights up, the ball firing motor 9 stops. The excitation of the relay 12 is not released even if the glass door 4 is subsequently closed because its self-holding circuit is activated. To release the self-holding of the relay 12, a magnet (not shown) is brought close to the surface of the game board 3 where the reed switch 15 is hidden, and the reed switch 15 is turned on by its magnetic force. Then, the relay 13 is energized and its normally closed relay contact 16 is turned off, so that the self-holding of the relay 12 is released. In other words, when the glass door 4 is opened by an authorized clerk, the glass door release indicator lamp 10 can be turned off immediately by opening the glass door 4 and then bringing the magnet close to a predetermined position on the game board 4. However, if it is by the person who released the fraud that is not the case, the reed switch 15
Since the player does not know the procedure for releasing self-holding, the display lamp 10 continues to light up every time the glass door is opened, and at the same time, the batted ball firing motor 9 does not rotate, so the game cannot be continued, and cheating can be easily discovered. Note that, if necessary, an alarm buzzer or the like for illegal display may be connected instead of the glass door open indicator lamp 10.

[Effects of the Invention] As explained above, the present invention prevents the self-holding of the relay for unauthorized display from being released unless the reed switch is activated, and has the effect of preventing unauthorized opening of the glass door using a duplicate key. be. Furthermore, since it is constructed with a simple circuit, it can be installed at low cost and fraud can be effectively prevented, making it very useful for pachinko parlors. What's more, simply by bringing the magnet close to the reed switch inside the glass door opening, the self-holding of the relay for the fraudulent display is released and the operation can be easily performed on the spot, so the advantage is that it can be dealt with without the complicated procedures required in the conventional case. There is.
