Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a board storage box of a pachinko machine for storing a circuit board having a ROM of the pachinko machine.
[0002]
[Prior art]
Since the program for determining the winning rate of the pachinko machine is written in the ROM, there has been a case where an illegal ROM is obtained by illegally replacing the regular ROM with a modified ROM. For this reason, recently, a device has been devised in which a circuit board including a ROM is housed in a box and the ROM cannot be replaced unless the lid of the box is destroyed, and many patents have already been filed. However, since most of the conventional board storage boxes only prevent the lid from being opened illegally, the mounting screws on the board are destroyed from the back, and the internal ROM is replaced without opening the lid. It turns out that it is not effective for the new trick.
[0003]
[Problems to be solved by the invention]
The present invention solves the above-mentioned conventional problems so that if the lid is opened improperly, the trace remains on the lid, and the internal ROM can be replaced even if the mounting screw is destroyed from the back side. This is intended to provide a substrate storage box for a pachinko machine that can be sealed again after inspection by the police after shipment from the manufacturer is completed.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention includes a bottomed box-shaped base body in which an upper surface is accommodated and a lid that can be slid into the upper surface only from a specific direction. A board storage box for a pachinko machine consisting of a body,
Provided with a horizontal engaging claw at the front and rear ends of the box-shaped substrate in the sliding direction, and provided with an engaging claw receiving portion into which the engaging claw fits at the front and rear ends of the lid in the sliding direction.
A plurality of locking holes whose upper surfaces are covered are formed on the sides of the lid, and the upper surfaces of the locking holes are covered with a locking hole cover integrated with the lid by connecting pieces , and a box-shaped base A plurality of locking pin storage holes are formed, and when the lid body is slid into the box-shaped base and fitted into any of the locking pin storage holes, the elastic body is repelled by the elastic means. A lock pin that fits into the lock hole from below is housed.
[0005]
According to this invention, when the lid is slid and fitted into the box-shaped base body from a specific lateral direction, the locking pin housed in the lock pin housing hole of the box-shaped base body is repelled by the elastic means. Then, it can be fitted into the lock hole of the lid from below, and thereafter it cannot be opened by sliding in the opposite direction. For this reason, the lid cannot be opened unless the surface of the locking hole of the lid is destroyed. In addition, the box-shaped base has a bottom, and even if the mounting screw for attaching the circuit board to the box-shaped base is broken from the back side of the board, the ROM cannot be replaced unless the lid is opened.

As shown in these drawings, the substrate storage box includes a plastic box-like base 1 and a plastic lid 2. The box-shaped substrate 1 has a shape with a bottom and an upper surface opened, and is attached to the board by appropriate attachment means (not shown). A boss 3 is provided at the bottom of the box-shaped substrate 1, and a circuit board 4 on which a ROM is mounted is fixed to the upper surface of the boss 3 by mounting screws 5 and is housed inside the box-shaped substrate 1. .
[0007]
The lid 2 has the following configuration so that it can be fitted to the box-shaped substrate 1 by sliding from a specific direction indicated by an arrow in FIGS. 1 and 3. First, as shown in FIGS. 1 and 4, a vertical wall 6 protrudes beyond the opening edge on one end face of the box-like base body 1, and a plurality of engaging claws 7 are horizontally inwardly directed at the upper end. Is formed. On the other hand, as shown in FIG. 3 and FIG. 5, a plurality of engaging claw receiving portions 8 are formed at the front end portion in the sliding direction of the lid body 2 so as to drop into the L-shaped cross section from the surface. Is inserted into the box-shaped base body 1 by sliding it in a specific direction, the engaging claw 7 of the box-shaped base body 1 fits into the engaging claw receiving portion 8 of the lid 2 and cannot be lifted.
[0008]
Further, a hollow portion 9 is integrally formed at the other end (rear end in the sliding direction) of the box-shaped substrate 1, and both end portions thereof are cut off leaving the upper surface to form horizontal engaging claws 10. On the other hand, the engaging claw receiving portions 11 that are lowered into the L-shaped cross section from the surface are also formed at both corresponding end portions of the lid body 2, and when the lid body 2 is slid to the box-shaped base body 1 from a specific direction, The engaging claw 10 of the box-shaped base body 1 is fitted into the engaging claw receiving portion 11 of the lid 2. Accordingly, the lid 2 can be attached and detached only from the direction of the arrow.
[0009]
The lock structure of the lid 2 with respect to the box-shaped substrate 1 is as follows.
First, a plurality of locking holes 12 are formed between the engaging claw receiving portions 11 of the lid 2. As shown in FIG. 3, these lock holes 12 have a cylindrical shape with an open lower surface, and the upper surface is covered with a lock hole cover 17 integrated with the lid 2 by a thin connecting piece 13. Yes. In this embodiment, the number of the locking holes 12 is four, but the number can be set as appropriate.
[0010]
On the other hand, as shown in FIGS. 1 and 3, a plurality of locking pin storage holes 14 are formed in the hollow portion 9 of the box-shaped substrate 1 so as to correspond to the plurality of locking holes 12 of the lid 2. . The locking pin accommodation hole 14 is a bottomed cylindrical shape having an open upper surface, and the upper surface is a height that matches the lower surface of the locking hole 12 of the lid body 2 when the lid body 2 is fitted into the box-shaped base body 1. It has become. A locking pin 15 is stored in any one of the plurality of locking pin storage holes 14.
[0011]
The locking pin 15 has a columnar shape or a cylindrical shape, and includes an elastic means 16 such as a spring on the lower surface thereof. For this reason, as shown in FIG. 6, when the lid 2 is slid and fitted to the box-shaped base 1 and the locking hole 12 of the lid 2 coincides with the locking pin storage hole 14, as shown in FIG. The locking pin 15 is repelled by the elastic means 16 and fits into the locking hole 12 of the lid 2 from below, and thereafter the lid 2 is locked so that it cannot be slid. In order to release this lock, it is necessary to cut the connecting piece 13 to remove the lock hole cover 17 and to remove the lock pin 15 and then slide the lid 2.
[0012]
The substrate storage box of the present invention having the above-described structure is shipped from the manufacturer with the lock pin 15 stored in the first lock pin storage hole 14 and the lid 2 locked as described above. Then, at the time of an inspection performed by the police, the lock hole cover 17 of the cover body 2 corresponding to the first lock pin housing hole 14 is broken and removed, and the lock body 15 is pulled out before the cover body. 2 is slid to open the lid 2. After the inspection, the locking pin 15 and the elastic means 16 are transferred from the first locking pin storage hole 14 to the second locking pin storage hole 14, and the lid body 2 is slid and fitted into the box-shaped substrate 1. As a result, the lid 2 is locked again. In addition, what is necessary is just to repeat said operation, when a test | inspection is performed in multiple times.
[0013]
Thus, since the board storage box of the present invention has a structure in which the lid 2 is directly locked to the box-shaped base 1, the lid 2 can be removed even if the mounting screws 5 of the circuit board 4 are broken from the back of the board. The internal ROM cannot be replaced unless the lock hole cover 17 is destroyed. Further, if the lock hole cover 17 is illegally destroyed, the trace clearly appears on the lid 2, so that the occurrence of the incident can be known.
[0014]
In this embodiment, as shown in FIG. 2, substrate mounting screw obscuration portions 18 are provided to project at two locations on one side of the lid body 2.
