The present invention includes a first switch that operates as the movable lock member moves in the unlocking direction, and a second switch that operates as the cam rotates in the unlocking direction by the code key of the locking device, and only the first switch operates. When the first and second switches are activated simultaneously, an alarm device such as a buzzer is activated, and when the first and second switches are activated simultaneously, the alarm device is deactivated.
When an unauthorized person attempts to open the door without using the code key, an alarm device is activated to help prevent crime.

An embodiment of the present invention will be described.

Reference numeral 1 indicates a pachinko machine main body, in which a front frame 4 that can be opened to the front by a shaft 3 is provided on the front side of a peripheral frame 2 that is installed and fixed on a gaming machine.
A window hole 5 is provided in which a glass frame 6 which can be opened by opening only the rolling surface of the game board is fitted.

A locking engagement piece 7 is provided on the opening/closing side of the glass frame 6 so as to protrude rearward. On the back side of the front frame 4, there are locking key pieces 12 that correspond to the opening/closing side parts of the glass frame 6 and engage the frame 4 itself with a locking mechanism (not shown) provided on the peripheral frame 2. Attach the glass frame locking device board 11 that protrudes rearward, and attach the mounting plate 13 in the left and right direction.
A locking device 2 consisting of a cylinder lock is installed in the middle part of the height direction.
Fix 0. The length of the lock device is made to approximately match the thickness of the front frame 4, and the code key insertion slot 21 of the lock device is exposed on the front side of the pachinko machine main body 1. The locking device 20 has a movable portion 22 that protrudes to the rear surface of the mounting plate 13 and fixes the cam 23 therein. A rear protruding piece 14 is provided on the mounting plate 13, and a movable locking member 17 that is pulled upwardly, that is, in the locking direction by the biasing force of the spring 16, is fitted between the rearward protruding piece 14 and the splint plate 15 on the inside thereof. A lock release arm 18 is provided which projects from a longitudinal long hole 14a formed in the rear projecting piece 14.

The movable part of the lock device 20 to which the cam 23 is attached is arranged further inside the splice plate 15. Cam 23 is plate 1
The cam 23 protrudes slightly from the elongated hole 14b formed in the rear protruding piece 14 and the movable lock member 1.
7 from above.

An engagement metal frame 24 corresponding to the glass frame 6 is attached to the edge of the window hole 5 of the front frame 4, and the lock release arm 1 is attached to the edge of the window hole 5 of the front frame 4.
A locking piece 25 is provided which presses the pressure receiving arm 26 and descends against the spring force (not shown) when the lock is released during the unlocking operation of 8, and is engaged with the locking engagement piece 7 from below. A locking notch 27 for locking is formed. As the lock release arm 18 descends, the locking piece 25 is guided forward by a stationary guide pin 29 inserted into the diagonal guide hole 28, and the locking piece 7 is opened by the locking notch 27. The glass frame 6 is pushed out slightly by the inclined guide surface 30 at the same time as the lock is released.
Since the configurations of each part described above are all well known, detailed illustrations and explanations will be omitted.

In this embodiment, in the known pachinko machine lock mechanism exemplified above, the first switch 31 is operated by moving the movable lock member 17 or the lock release arm 18 against the bias, and the engagement notch 1 of the cam 23 is used.
A second switch 32 is provided which operates by rotation of the movable lock member 17 by pushing it down through the lower edge of the second switch 32. Attach the distorted piece 32b. The first and second switches 31 and 32 move the movable locking member 17 without relying on the cam 23, thereby causing a switch operation when an attempt is made to illegally release the lock on the glass frame, and the latter causes the cam 23 to move. Therefore, the switch operation occurs only when the movable lock member 17 is moved normally in the unlocking direction (when the second switch 32 operates, the first switch 31 operates). In this embodiment, as shown in FIG. ninot circuit 42
A discrimination circuit 41 is provided in which a first switch 31 and a second switch 32 are connected to one input terminal of the AND circuit 43, and the output signal of the discrimination circuit 41 is held by a holding circuit 51. When the second switches 31 and 32 operate simultaneously and there is input to both input terminals of the AND circuit 43 of the OR circuit 42, only the lamp 52 blinks and only the first switch 31 or the second switch 32 operates independently. OR circuit 4
If there is an input only to 2, the connection is made to drive the lamp 52 and the relay 53a of the alarm device 53 such as a buzzer. When the balls of a pachinko machine are hit by rotating the motor as is well known, a signal instructing the alarm device 53 to drive can simultaneously interrupt the circuit of the motor so that no game can be played.

Since only the second switch 32 is activated only when there is a lock release failure, which is rare, the alarm device 53 is activated only when only the first switch 31 is activated, that is, when the lock is illegally released. become.

The lamp 52 and the alarm device 53 are attached to the pachinko machine main body 1 as shown in Fig. 1, but they can also be provided in a monitoring room for monitoring the status of the entire pachinko machine, with numbers assigned to each pachinko machine. .

The first switch 31 and the second switch 32 may be mounted on the lock device board 11 as shown, or on separate plates 11a as shown in FIG.
The point is that it is sufficient to differentiate the switch operations as described above.

As mentioned above, the security device of the present invention has the following features:
From the front of the machine, push the foreign object through the small gap formed by the glass frame 6, etc. to the back side of the machine and remove the movable lock member 1.
If a fraudulent attempt is made to release the lock of the glass frame 6 by pushing down the lock release arm 18 (or pressure receiving arm 26) of 7, only the first switch 31 will be activated by pressing the switch press operation piece 31a, and as described above, Since the warning device 53 such as a buzzer is activated and the lamp 52 is turned on at the same time, it becomes clear which Pachinko machine is being used fraudulently. Also, those who commit fraud are surprised by the activation of the alarm device 53 and stop their fraud.

When the code key is inserted into the code key insertion slot 21 of the locking device 20, the movable part 22 and the cam 23 are rotated, and the movable lock member 17 is pressed down against the bias. switch 3
1 and 32 are activated simultaneously, and at this time, the alarm device 53 is not activated as described above, and only the lamp 52 blinks quietly to indicate that the lock is being released.

As clarified by the description of the above embodiments, when the locking mechanism of a pachinko machine is normally unlocked by rotating a cam using a matching key, the present invention uses a movable locking member that moves in the unlocking direction and The mechanism of the locking mechanism is skillfully utilized in such a way that the first and second switches are operated simultaneously by a cam, and only the first switch is operated when the locking mechanism is released by operating only the movable locking member. This creates a clear switch operation division in which the first and second switches are operated simultaneously or only the first switch is operated independently, and the alarm device is activated when the lock is released. The present invention has the effect of providing a crime prevention device with a simple configuration that can easily generate electrical control that causes the device to turn on or remain inactive, thereby preventing fraud that occurs in pachinko machines.
