It is configured not to operate normally. That is, the main control board 41 has a circuit configuration that can operate normally on condition that it is electrically connected to the child board 45 via the fitting connector C1.

Therefore, as will be described in detail later, if the connector can be destroyed when the substrate case 110 is opened,
Even if unauthorized modification is added to the main control board 41, the main control board 41 and the sub board 4 will be used thereafter.
5 cannot be electrically connected to each other, and the main control board 41 itself becomes inoperable. Therefore, it is possible to prevent the modified main control board 41 from being used in an unauthorized game. And, when the board case 110 is opened, the destruction protrusion 134 described below plays a role of breaking the fitting connector C1.

The destruction protrusion 134 is disposed in the vicinity of the main control board 41 on the inner surface side of the bottom wall 131a in the top case 130, and is a position that substantially faces the child board side connector 453 in the front-rear direction when the board case 110 is closed. The connector 453 can be locked with respect to the relationship. The breaking protrusion 134 is supported on the inner surface side of the bottom wall 131a of the top case body 131 in a cantilevered manner and is bent in an L shape, and is protruded on the free end side of the elastic arm 134a. It consists of the claw part 134b and can be elastically deformed in the direction (front-rear direction) substantially orthogonal to the sliding direction of the substrate case 110. The claw portion 134b includes an inclined surface 134c that is inclined so as to increase in thickness from the distal end side toward the proximal end side, and the engaging slope 1
A locking surface 134d that is formed on the base end side of 34c and can be locked to the sub board-side connector 453,
It is formed by continuous connection.

When the top case 130 is slid in the right direction (closing direction) with respect to the bottom case 120, the breaking protrusion 134 is in sliding contact with the wall surface of the board-side connector 453, and the inclined surface 1.
When the top case 130 is slid in the left direction (opening direction) with respect to the bottom case 120 while the sliding movement is permitted by elastically deforming in a direction away from the board side connector 453 by the action of 34c, The stop surface 134d is locked to the wall surface of the board-side connector 453 to inhibit the slide movement (as a result, if the board case 110 is forcibly opened, the child board-side connector 453 is broken by the breaking protrusion 134). .

Next, the operation when assembling the main control board case unit 100 according to the present embodiment will be described with reference to FIG. Here, FIG. 12 is a schematic diagram for explaining the operation of the connector destruction structure.

Subsequently, the top case 130 is slid onto the bottom case 120, and the substrate case 1
10 is closed. At this time, as shown in FIG. 12A, when the top case 130 is slid in the closing direction with respect to the bottom case 120, the breaking protrusion 134 of the top case 130 abuts on the child board side connector 453 and the inclined surface. The connector 45 is operated by the action of 134c.
By pressing in a direction away from 3, the destruction protrusion 134 is elastically deformed and bent. Then, as shown in FIG. 12B, when the top case 130 is completely slid onto the bottom case 120, the original free posture is obtained by its own restoring elasticity when the breaking projection 134 has passed over the sub board side connector 453. Then, the claw portion 134b of the destruction projection 134 and the sub board side connector 453 are engaged.

When the board case 110 is closed in this way, the main control board 41 and the sub board 45 are accommodated in the board case 110 in a state adjacent to the left and right. Here, the bottom case 120
Since the sliding direction of the top case 130 with respect to the main board side connector 413 and the sub board side connector 453 coincides with the sliding direction of the top case 130 with respect to the bottom case 120, Side connector 413 and sub board side connector 45
3 are board-to-board connected, and the main control board 41 and the sub board 45 are connected to each other via the fitting type connector C1.

With the substrate case 110 closed as described above, the shaft portion 141 of the lock member 140 is inserted into the bottom side lock portion 122 and the top side lock portion 132, and the bottom side lock portion 122 is connected via the lock member 140. By engaging and connecting the top side lock portion 132, the bottom case 120 and the top case 130 are locked and fixed so that they cannot be opened. Therefore, the substrate case 110 is not opened unless the top side lock part 132 in a state of being engaged and connected to the bottom side lock part 122 by breaking the connection part 132b of the top case 130 is separated from the top case body 131. Absent.

In this way, the main control board 41 and the sub board 45 are integrally assembled to the board case 110, whereby the assembled main control board case unit 100 is completed, and the main control board case unit 100 is played as a single individual. The panel 10 can be attached to and detached from the back side.
At this time, in the board case 110, the main control board 41 and the sub board 45 are fitted to the fitting type connector C.
1 and a predetermined electrical signal (health check signal) is input from the slave board 45 to the main control board 41 as described above.
Can operate normally on the basis of a program or the like stored in a ROM (electronic device 411).

Further, when the main control board case unit 100 is assembled integrally in this way, it is difficult to access the main control board 41 accommodated in the board case 110 from the outside. Here, as described above, the seal seal 150 is mounted with an IC chip and an antenna line, and even if the seal seal 150 is held inside the substrate case 110, various information stored in the IC chip (
For example, information regarding pachinko gaming machines PM, identification information of the main control board 41, and the like) can be read from the outside by a reader without opening the board case 110.

Next, in the main control board case unit 100 according to the present embodiment, the board case 110
The action when opening the door will be described.

First, in order to open the substrate case 110, the connecting portion connecting the top side lock portion 132 and the top case body 131 in the unauthorized opening prevention structure is cut using a tool such as a nipper,
The top-side lock part 132 engaged with the bottom-side lock part 122 via the lock member 140 is separated from the top case body 131. As a result, the connection between the bottom case 120 and the top case 130 is broken, and the substrate case 110 can be opened.

Subsequently, the top case 130 is slid in the opening direction with respect to the bottom case 120. At this time, because the destruction protrusion 134 of the top case 130 is locked to the sub board side connector 453 of the bottom case 120 as shown in FIG. The sliding movement of the top case 130 with respect to the bottom case 120 is hindered. If the top case 130 is forcibly slid from this state, a load of a certain level or more is applied from the destruction protrusion 134 to the child board side connector 453, so that the child board side connector 453 is broken by being pressed by the destruction protrusion 134. It will be. Here, “destroy” of the sub board side connector 453 means that the sub board side connector 453 itself is damaged and cannot be engaged with or electrically connected to the main board side connector 413, or the housing 413a or the contact terminal (see FIG. In addition to the case where traces of damage remain to the extent that they can be visually recognized, the sub-board connector 453 itself is separated from the sub-board 45 without being damaged, and is substantially separated from the main control board 41 and the sub-board 45. This includes cases where the electric connection becomes impossible.

When the board case 110 is opened in this way, the child board side connector 453 is surely destroyed and the trace remains clearly, so that an unauthorized access to the main control board case unit 100 can be easily found. it can. Furthermore, if the sub board side connector 453 is broken, the main control board 41 and the sub board 45 are disconnected from each other, and the main control board 41 becomes inoperable. Remodeling actions are prevented in advance (for example, even if tampering such as ROM replacement is performed).

In addition, when the substrate case 110 is opened, even in the seal seal structure, the seal seal 150 is broken by the cutter member 151, so that various information stored in the IC chip of the seal seal 150 becomes substantially unreadable. Even in this seal seal 150, a trace of opening the substrate case 110 remains.

As described above, according to the main control board case unit 100 according to the present embodiment, the board case 110.
Is opened, the destruction protrusion 134 provided on the top case 130 side comes into contact with the sub board side connector 453 provided on the bottom case 120 side to destroy the sub board side connector 453, whereby the board case 110 Can clearly detect the illegally opened traces and detect the illegal acts at an early stage, and the electrical connection between the main control board 41 and the sub board 45 via the fitting type connector C1 is lost. As a result, the main control board 41 itself becomes inoperable, so that it is possible to prevent unauthorized actions such as replacement or modification of electronic components with respect to the main control board 41. Therefore, according to the present embodiment, there is an effect that it becomes possible to contribute to prevention and early detection of fraud.

Further, when the board case 110 is opened, the sub board side connector 453 is destroyed, so that the sub board 45 side is damaged to some extent, but the main control board 41 itself is not damaged and can be reused. , It will be possible to minimize the damage caused by unauthorized opening.

By the way, in the above-described embodiment, the board-to-board connector is exemplified and described as the fitting connector C1 for connecting the main control board 41 and the sub board 45. However, for example, other connectors such as a movable connector are used. A connector may be applied. Here, FIG. 13 shows a schematic diagram when a movable connector C2 is applied as a modification of the connector destruction structure.

As shown in FIG. 13, the connector destruction structure according to this modification is configured mainly with a main control board 41, a sub board 45, and a movable connector C2, and the above-described implementation in that the destruction protrusion is not a constituent element. It is different from the form. In FIG. 13, only the main part is extracted from the main control board case unit 100 and shown.

The movable connector C2 includes a main board side connector 414 as a receptacle connector provided at the right end of the main control board 41 and a sub board side connector 454 as a plug connector provided at the left end of the sub board 45. A board-to-board connector. Movable connector C
2 is, for example, a printed circuit board connector (1.25 manufactured by Japan Crimp Terminal Manufacturing Co., Ltd.
FJ connector) is applied.

The main board-side connector 414 includes a receptacle housing 414a mounted on the main control board 41, and a plurality of contact terminals (not shown) held in alignment along the width direction of the receptacle housing 414a. It is formed. The receptacle housing 414a is integrally molded using an electrically insulating material such as a resin, and a fitting recess 414b that opens upward and rightward is formed in the receptacle housing 414a. A contact terminal (not shown) is formed using a conductive metal material, one end (contact portion) is press-fitted and held in the fitting recess 414b, and the other end (lead portion) is on the wiring pattern of the main control board 41. Are joined by soldering.

The sub board side connector 454 is a plug housing 454a mounted on the sub board 45.
And a plurality of contact terminals (not shown) held in an aligned state along the width direction of the plug housing 454a. The plug housing 454a is integrally molded using an electrically insulating material such as resin. The housing base portion 454b is attached to the daughter board 45, and is pivotally supported by the housing base portion 454b so as to swing around the axis X. And a fitting convex portion 454c that is freely attached. A contact terminal (not shown) is formed using a conductive metal material, one end (contact portion) is press-fitted and held in the fitting convex portion, and the other end (lead portion) is a wiring of the child board 45. It is joined on the pattern by soldering. Here, as long as the contact terminal can be displaced according to the swinging motion of the fitting convex portion 454c, the contact terminal may be a combination of two divided contacts that can move relative to each other, or elastically deformed. Possible contacts may be used. The sub board side connector 454
The raised position (see FIG. 13 (a)) where the fitting convex portion 454c stands upward with respect to the housing base portion 454b, and the lying position (FIG. 13 (b)
))), And the fitting convex portion 454c is tilted from the standing position to the lying position, and the fitting convex portion 454c of the sub board side connector 454 is moved to the main board. By fitting into the fitting recess 414 b of the side connector 414, contact terminals (not shown) are connected to each other and the main control board 41 and the sub board 45 are electrically connected.

Further, in order to enable the swing operation (tilt operation) by accessing the slave board side connector 454 from the outside of the board case 110 at a position aligned with the slave board side connector 454 on the bottom wall 131a of the top case 130. The operation opening 135 is penetrating front and back. As a result, when the board case 110 is closed, the fitting convex part 454c of the sub board side connector 454 can be swung up and down through the operation opening 135 of the top case 130, and the fitting convex part 454c is tilted from the standing position. The main board side connector 414 and the sub board side connector 454 can be connected by tilting to the position and fitting with the fitting recess 414b. In addition,
The operation opening 135 is closed by a shielding member 136 that is somewhat larger than the operation opening 135 after the main board side connector 414 and the sub board side connector 454 are connected.

Next, the operation of the connector destruction structure having such a configuration will be described. In addition, since the operation | movement regarding an unauthorized opening prevention structure and a seal seal structure has already been described, the description is abbreviate | omitted here.

First, the main control board 41 is screwed to the inner surface side of the top case 130 and the subsidiary board 45 is screwed to the inner surface side of the bottom case 120. At this time, as shown in FIG. 13 (a), the fitting convex portion 454c of the sub board-side connector 454 mounted on the sub board 45 is set in an upright position that is swung upward.

Then, the top case 130 is slid onto the bottom case 120 and the substrate case 1
When 10 is closed, the main control board 41 and the sub board 45 are accommodated in the board case 110 in a state adjacent to the left and right. At this time, the main control board 41 and the sub board 45 are arranged in substantially the same plane in a state of being close to each other, and the main board side connector 414 and the sub board side connector 454 are arranged opposite to each other on the left and right.

Subsequently, a finger is put into the board case 110 from the operation opening 135 of the top case 130, and the fitting convex part 454c of the sub board side connector 454 is swung downward as shown in FIG. Tilt from position to fall position. Thereby, the fitting convex part 454c of the sub board side connector 454 is fitted into the fitting concave part 414b of the main board side connector 414 (connectors are connected), and the main control board 41 and the sub board 45 are movable connectors. It will be electrically connected via C2.

And as shown in FIG.13 (c), the shielding member 136 is covered on the operation opening 135 of the top case 130, for example, the surrounding wall part of the shielding member 136 and the operation opening 135 using well-known welding methods, such as ultrasonic welding. , The operation opening 135 is closed by the shielding member 136, so that the main control board 41 cannot be accessed from the outside of the board case 110.

Subsequently, the bottom case 12 is used to open the substrate case 110 thus assembled.
The top case 130 is slid in the opening direction with respect to zero. At this time, the sliding direction (left and right direction) of the top case 130 with respect to the bottom case 120 and the removal direction (substantially vertical direction) of the sub board side connector 454 with respect to the main board side connector 414 are different directions. When the case 130 is forcibly slid, the child board side connector 454 is pulled in a direction (sliding direction) in which the main board side connector 414 cannot be removed, and a load of a certain level or more is applied to the connectors 414 and 454 in the fitted state. Therefore, at least one of the main board side connector 414 and the sub board side connector 454 is destroyed.

Therefore, according to the connector breaking structure according to this modification, the sliding direction of the board case 110 and the fitting / removing direction of the connector are different from each other, and when the board case 110 is opened, the fitting state is movable. Since the connector 414, 454 is destroyed by applying a load above a certain level to the connector C2, the trace of the board case 110 being illegally opened can be clearly left, and the fraud can be detected at an early stage. Main control board 41 via movable connector C2
Since the main control board 41 itself becomes inoperable due to the disconnection of the electrical connection between the main control board 41 and the sub board 45, it is possible to prevent unauthorized actions such as replacement or modification of electronic components with respect to the main control board 41. It becomes. Therefore, also in this modification, there exists an effect that it becomes possible to contribute to prevention and early detection of fraudulent acts similar to the above-mentioned embodiment.
