The optical sensor corresponding to the upper engaging member 12 is referred to as a third sensor 200C, and the optical sensor corresponding to the lower engaging member 13 is referred to as a fourth sensor 200D.

The fraud detection control section 300 determines a predetermined normal unlock detection mode, which will be described later, and a detection mode of ON / OFF signals actually supplied from the first to fourth sensors 200A, 200B, 200C, 200D. This is a part for comparing and outputting a fraudulent signal when there is a difference between the two.

In the pachinko machine 1 configured as described above, when the inner frame 3 is opened with respect to the outer frame 2, the pachinko machine 1 is connected by the urging force of the lower urging spring 143 as shown in FIGS. The regulating protrusion 14a of the operating member 14 is in contact with the lower end of the regulating slot 131a provided in the lower bracket 131, and the upper engaging member 12 extends substantially horizontally toward the rear. At this time, the lower engaging member 13 is connected to the connecting shaft 1 of the connecting operating member 14 by the urging force of the swing urging spring 132.
Reference numeral 42 is in contact with the upper end of the shaft insertion hole 13c, and extends rearward with the tip end slightly upward.

When the inner frame 3 is closed and moved with respect to the outer frame 2 from this state, the guide inclined surfaces 12 b and 13 b provided on the respective engaging members 12 and 13 are brought into contact with the engaging portions 11 b of the engaging plate 11. In contrast, the guide members come into contact with the lower edges, and the engagement members 12,
Each of the members 13 swings downward gradually against the urging force of the above-described lower urging spring 143 and the oscillating urging spring 132. When the closing movement of the inner frame 3 further progresses and the inner frame 3 is completely closed with respect to the outer frame 2 soon, the guide inclined surfaces 12b and 13b and the respective engaging portions 11b
At the same time when the state of contact with is released, the respective engagement members 12 and 13 are moved downward by the downward biasing spring 143 and the swing biasing spring 1.
By the urging force of 32, it will swing upwards,
As shown by T1 in FIG. 4, the individual hook portions 12a, 13
a is held in a state of abutting engagement with the back surface of each engagement portion 11b. Accordingly, the engaging members 12, 1 which engage with each other are provided.
The opening movement of the inner frame 3 with respect to the outer frame 2 is prevented by the action of the 3 and the engaging portion 11b, and it becomes difficult for anyone other than those involved in the game store to open the pachinko machine 1 carelessly. .

At this time, the sensor detecting portion 15c of the rotation operating member 15 remains substantially horizontally extending toward the outer frame 2. The upper engagement member 12 has returned to a state in which it extends substantially horizontally rearward. Further, the upward engagement of the lower engagement member 13 is restricted by the contact engagement with the engagement portion 11b.
Similarly, the connecting shaft 142 of the connecting operating member 14 extends substantially horizontally toward the rear, and is held in a state of contact with the lower end of the shaft insertion hole 13c. As a result, the fraud detection control unit 3
5A, an ON signal is output from each of the first sensor 200A and the second sensor 200B, and the third sensor 200C and the fourth sensor 200 are output as indicated by T1 in FIG. From 200D all OF
The F signal will be output.

On the other hand, the cylinder lock 100
When the key K is inserted into the keyhole 101 of FIG. 1 and the inner cylinder (not shown) is rotated clockwise toward the front, the rotation operating member 15 is rotated.
Of the connecting operating member 14
b, first, as shown by T2 in FIG. 4, the coupling operating member 14 starts to move upward and the rotation operating member 1
The fifth sensor detector 15c moves to the gap between the second sensors 200B. At this time, the connection operating member 14
With the upward movement, the upper engaging member 12 immediately starts swinging downward, but with respect to the lower engaging member 13, the connecting shaft 142 of the connecting operating member 14 moves up the shaft insertion hole 13c. Just move and do not start rocking. As a result,
In the state indicated by T2 in FIG. 4, T in FIG.
As shown in FIG. 2, while the detection signal from the second sensor 200B switches from ON to OFF, the first, third, and fourth
No change occurs in the detection signals from the sensors 200A, 200C, 200D.

As the rotation of the inner cylinder (not shown) progresses, the state of engagement between the upper engaging member 12 and the corresponding engaging portion 11b is released, as indicated by T3 in FIG. ,
Accordingly, the detection signal from the third sensor 200C becomes OF
F → ON (T in FIG. 5A).
3, T4), and thereafter, as shown by T4 in FIG. 4, the connecting shaft 142 of the connecting operating member 14 in the lower engaging member 13.
Comes into contact with the upper end of the shaft insertion hole 13c.

When the inner cylinder (not shown) further rotates after T4 in FIG. 4, the lower engaging member 13 also swings downward together with the upper engaging member 12, and eventually, as shown in FIG. As shown at T5 and T6, the state of engagement between the lower engaging member 13 and the corresponding engaging portion 11b is released. Therefore, if the inner frame 3 is opened and moved relative to the outer frame 2 from this state, the pachinko machine 1 can be opened, and various types of maintenance work can be performed on the pachinko machine 1. Become.

In the state indicated by T5 and T6 in FIG. 4, the sensor detecting portion 15c of the rotation operating member 15 deviates from the light emitting portion of the second sensor 200B, and the light beam emitted from the light emitting portion Again reaches the light receiving section. As a result, as indicated by T5 and T6 in FIG. 5A, the detection signals from the second sensor 200B and the fourth sensor 200D are respectively switched from OFF to ON.

In any state of T2 to T6 in FIG. 4, if the operating force of the key K inserted into the keyhole 101 of the cylinder lock 100 is removed, the upper engaging member 12 and the lower engaging member 13 returns to a state of extending substantially horizontally rearward again by the urging forces of the downward urging spring 143 and the oscillating urging spring 132, and returns to the state shown by T1 in FIG. .

Here, according to the fraudulent detection device, when the above-mentioned regular unlocking operation is performed, the detection states and detection procedures of the first to fourth sensors 200A, 200B, 200C, 200D are shown in FIG. This is limited to the normal unlock detection mode shown in a). That is, when the normal unlocking operation is performed, the first to fourth sensors 200A, 200B,
The detection mode of 200C and 200D is “ON, ON, OF
F, OFF ”→“ ON, OFF, OFF, OFF ”→
"ON, OFF, ON, OFF" → "ON, ON, O
N, ON ", and the detection states are created in the order described.

On the other hand, for example, when an operation of directly swinging the upper engaging member 12 by inserting a metal piece through a gap between the pachinko machine 1 and the game island or the machine between the pachinko balls is performed. As shown by F1 in FIG. 5B, this may occur in a normal unlocking operation in which the detection states of the first to fourth sensors 200A, 200B, 200C, 200D are "ON, ON, ON, OFF". Will create a missing detection state.

When the operation of directly swinging the lower engagement member 13 is performed, as shown in FIG.
To the fourth sensor 200A, 200B, 200C, 200
The detection state of D is “ON, ON, ON, ON” and the same as the normal unlocking detection mode, but “ON, O
FF, OFF, OFF ”and“ ON, OFF, ON,
Since the detection state “OFF” does not pass, the detection procedure cannot be performed by the normal unlocking operation.

Therefore, after the inner frame 3 is closed with respect to the outer frame 2, the first to fourth sensors 200A, 200B,
When the ON / OFF signal given from 200C, 200D creates one of the detection states indicated by F1 to F12 in FIG. 5B, or creates a detection procedure that cannot be performed by a regular unlocking operation. However, the fraud detection control unit 300 can determine that fraud has been performed, not a regular unlocking operation. Further, the fraud detection control unit 300 that has detected fraud, for example, outputs a fraudulent occurrence signal to the main body control circuit of the pachinko machine 1 so that the game ball cannot be fired, or a host computer or an alarm provided on the game island. Processing such as outputting a fraudulent occurrence signal and reporting the fraudulent occurrence is performed, so that damage to the game store due to fraud can be minimized.

In the above-described embodiment, a fraud detection device applied to a pachinko machine is exemplified. However, the first game machine structure and the second game machine structure are disposed so as to be openable and closable with each other. If it is, it can be applied to other gaming machines. Further, in the above-described embodiment when applied to a pachinko machine, only the space between the outer frame and the inner frame is illustrated, but the inner frame and a glass frame holding a glass plate,
It may be applied to other places. Further, as the locking device, a device that releases the engagement member through the operation of the rotation operation member and the connection operation member when a normal unlocking operation is performed, but is not limited to these configurations, Further, it is not always necessary to provide two engagement members.

In the above-described embodiment, whether or not fraud has occurred is detected based on both the detection state of the detecting means and the detection procedure. Alternatively, it may be detected whether or not the operation is performed. In addition, although the optical type is exemplified as the detecting means, other detecting means such as a contact type, a magnetic type and the like may be used. Furthermore, after detecting a fraud, a fraudulent signal is output to the main body control circuit of the pachinko machine so that the game ball cannot be fired, or a fraudulent signal is output to a host computer or an alarm provided on the game island. Processing such as reporting occurrence of fraud is performed, but the processing after fraud detection is not necessarily limited to these.

[0033]

As described above, according to the present invention,
Detecting means for individually detecting the operating states of the plurality of operating members and the engaging members are provided, and if the detection result by these detecting means is different from the detection mode by the normal unlocking operation, it is determined that the fraud has occurred. I have to. Therefore,
When the engaging member is directly operated without going through the regular unlocking operation, a difference occurs in the detection mode by the detection means, and it is possible to judge this to be improper.
