Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sealing structure for a substrate storage box in a pachinko machine.
[0002]
[Prior art]
For example, in a pachinko machine equipped with a variable display device, a circuit board provided with a CPU or the like is provided in a box for controlling the variable display device. The box is configured by assembling two cases, but in order to prevent unauthorized modification of the circuit board or replacement with an illegally modified circuit board, a sealing paper has been attached to the joint of both cases.
[0003]
[Problems to be solved by the invention]
However, in the case of such a sealing structure with sealing paper, it is also assumed that the sealing paper is skillfully peeled off and pasted again without leaving any traces.
Therefore, as a countermeasure, there is also considered a method in which both cases are rigorously assembled by a method in which once the case is separated, such as bonding or welding, the joint portion is destroyed and cannot be reassembled.
On the other hand, for a box that contains a circuit board and is sealed as described above, a sampling inspection is performed by the police in order to check whether the circuit board has been tampered with or replaced. However, if both cases are sealed by the above-described method, the box must be discarded after the opening inspection, and another box must be prepared for each inspection.
The present invention has been invented in view of the above circumstances, and has an object to prevent sealing from being illegally released and to enable sealing again after once releasing the seal.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the invention of claim 1 is directed to a box main body in which a circuit board is accommodated, an opening formed in the box main body, and a shaft portion protruding from an end portion. By supporting the box body so that it can rotate around the axis and move along the opening edge of the opening, the shaft is moved from the initial position to close the opening to the opposite side of the opening.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
The substrate storage box of this embodiment is configured by assembling the box body 10 and the lid plate 30. The box body 10 includes a fixed side case 11 for fixing a circuit board (not shown) and a covering side case 12 assembled to the fixed side case 11 so as to cover the circuit board. Further, in the case of the present embodiment, the covering side case 12 includes a resin case 13 and a metal cover 14 that is integrated on the surface of the resin case 13.
Then, when the circuit board is fixed to the fixed side case 11 and the covering side case 12 is assembled thereto, a sealing paper (not shown) is attached to the joint of the cases 11 and 12 thereafter. Such a sealing structure is employed to prevent unauthorized modification of the circuit board or replacement with an illegally modified circuit board.
Note that it is desirable that the fixed case 11 and the covering case 12 are rigorously assembled by a method in which once they are separated, such as bonding or welding, the joint portion is destroyed and cannot be reassembled.
[0007]
An opening 15 is formed in the resin case 13 in a rectangular shape as shown in the figure. When the metal cover 14 is attached to the resin case 13, the resin case 13 is exposed to the outside in alignment with the window hole 16 opened at a corresponding position of the metal cover 14. It is like that. The opening 15 is arranged corresponding to the arrangement area of the electronic parts necessary for controlling the game operation such as a ROM mounted on the circuit board in the box body 10 and is sized so that the ROM can be taken out from here. Is formed. The opening 15 is opened and closed by a lid plate 30 described later, and is locked in a closed state by a locking means described later.
There are two types of closed states: the initial closed state, which is the first assembled state, and the reclosed state after the sampling inspection, and the cover plate 30 is held at each position (initial position and inverted position) in these states. Is done. The initial closed state means a state in which the cover plate 30 closes the opening 15 when the circuit board is accommodated in the box body 10 and sealed. In this initial closed state, the direction of the cover plate 30 is determined, and the lid plate 30 is locked in a state where displacement in the opening direction is restricted by an initial sealing lock piece 22 described later. Further, the re-closed state means a state in which the opening 15 is closed again after the lock in the initial closed state is released. In this re-closed state, the cover plate 30 is turned upside down with respect to the initial closed state with its long side parallel to the long side of the opening 15, and the re-sealing lock piece 32, which will be described later. It is locked so that it cannot be released from the outside.
[0008]
At the opening edge portion on the short side of the opening portion 15, an elongated pressing portion 17 along the length direction is integrally formed with the resin case 13, and is separated from the resin case 13 from the inside of the resin case 13. A component holding plate 18 is attached in parallel to the holding portion 17 by screws 19, and the holding portion 18 and the holding plate 18 constitute a pair of guide grooves 20 along the opening edge on the short side of the opening 15. Has been. A shaft portion 34 of a lid plate 30 described later is fitted into the guide groove 20. The holding plate 18 is formed with a lid plate receiving portion 21 that protrudes into the opening region of the opening portion 15 and supports the lid plate 30 that has been displaced to the closed state from the inside so as not to sink.
[0009]
At the opening edge on one long side of the opening 15, two pieces of initial sealing lock pieces (initial sealing lock means) 22 for locking the cover plate 30 in the initial closed state are integrated with the resin case 13. Is formed. This initial sealing lock piece 22 rises from the outer surface of the resin case 13 and bends toward the opening region side of the opening 15, and has a shape where the tip is stuck into the opening region toward the inside of the resin case 13, The front end is a locking claw 23 fitted into the lock hole 31 of the lid plate 30.
Further, the portion of the initial sealing lock piece 22 rising from the resin case 13 allows insertion of a tool (not shown) between the surface of the lid plate 30 when the lid plate 30 is in the initial closed state. The bent portion is a tool insertion portion 24 that is bent so that a gap is formed. When the tool is inserted into the tool insertion portion 24 and then squeezed, the initial sealing lock piece 22 is broken at the base end portion and separated from the resin case 13, so that the initial closing state by the initial sealing lock piece 22 is achieved. Is unlocked.
At the opening edge opposite to the initial sealing lock piece 22, a receiving piece 25 that can be locked with the resealing lock piece 32 provided on the cover plate 30 is directed inward from the inner surface of the resin case 13. Protrusively formed. When the re-seal lock piece 32 is engaged with the protruding end surface of the receiving piece 25, the lid plate 30 is locked in the re-closed state. Further, the receiving piece 25 is slightly elastically bent so as to escape from the resealing lock piece 32 during the engaging operation with the resealing lock piece 32.
[0010]
The lid plate 30 has a rectangular plate shape that closes the entire opening 15. Two lock holes 31 corresponding to the initial sealing lock piece 22 are formed in the vicinity of one long side of the cover plate 30 so as to penetrate the front and back. Further, a reseal lock piece 32 (reseal lock means which is a constituent element of the present invention) 32 corresponding to the receiving piece 25 of the opening 15 is formed at a position between the lock holes 31. The re-seal lock piece 32 protrudes from the lid plate 30 at a right angle, and a locking claw 33 is formed at the tip of the reseal lock piece 32 so as to protrude outward in the plate surface direction of the lid plate 30. The protruding direction of the re-seal lock piece 32 from the cover plate 30 protrudes to the outside of the box body 10 in the initial closed state, and protrudes to the inside of the box body 10 in the re-closed state. . In the re-closed state, the engaging claw 33 of the re-seal lock piece 32 is engaged with the front end surface of the receiving piece 25, and the cover plate 30 is locked in the closed state. The reseal lock piece 32 is slightly elastically bent so as to escape from the receiving piece 25 in the middle of the engaging operation with the receiving piece 25.
The cover plate 30 is formed with a pair of shaft portions 34 protruding coaxially from both ends along one long side thereof. The shaft portion 34 is fitted in the guide groove 20 so as to be capable of rotating around the shaft support and moving in the short side direction of the opening 15, so that the cover plate 30 is attached to the resin case 13 with the resin case. It is attached in a state in which detachment from 13 is restricted. The cover plate 30 is attached before the circuit board is stored in the box body 10.
The lid plate 30 is assembled with the shaft 34 positioned from the inner side of the resin case 13 to the upper right end of the guide groove 20 in FIG. 15 is closed, and the locking claw 23 of the locking piece 22 for initial sealing is inserted into the lock hole 31. In this state, the holding plate 18 is fixed to the resin case 13 with screws 19. Then, as shown by a solid line in FIG. 1, the shaft portion 34 is fitted in the guide groove 20, and the lid is held between the initial sealing lock piece 22 and the lid plate receiving portion 21 from the outside and the inside, respectively. The plate 30 is locked in the initial closed state. In this state, a sealing paper (not shown) is attached to the joint between the outer peripheral edge of the cover plate 30 and the opening edge of the opening 15. After the opening 15 is in the initial closed state in this way, the circuit board is housed in the box body 10 and sealed.
[0011]
When the circuit board is housed and sealed in the box main body 10 as described above, both cases of the box main body 10 are to be checked for sampling whether or not the electronic components on the circuit board have been illegally modified or replaced. The opening 15 is opened as follows without releasing the seal of the joints 11 and 12.
When opening the opening 15, the sealing paper affixed between the cover plate 30 in the initial closed state and the resin case 13 is peeled off, and the initial sealing lock piece 22 is attached to the base using a tool (not shown). The end portion is broken and separated from the resin case 13. Then, since the lock is released, the opening 15 can be opened by displacing the cover plate 30 in the opening direction as indicated by a chain line in FIG.
FIG. 2 is a perspective view of the initial sealing lock piece 22 before and after destruction. The initial sealing lock piece 22 located on the upper right side of the figure is shown by an imaginary line before breaking, and the initial sealing lock piece 22 located on the lower left side of the figure is separated from the resin case 13 due to the breakage. The state of the inverted posture is indicated by a solid line.
Further, once the initial sealing lock piece 22 is broken and unlocked, the initial sealing lock piece 22 cannot be locked again. Even if the initial sealing lock piece 22 is fixed to the resin case 13 and restored by an adhesive, the trace of destruction cannot be erased. Therefore, an effect of preventing the lock by the initial sealing lock piece 22 from being illegally released can be expected.
In the initial closed state, the resealable lock piece 32 protrudes to the outside of the resin case 13, so that the resealable lock piece 32 and the opening edge of the opening 15 are opened when the lid plate 30 is opened. There is no risk of interference.
[0012]
After the sampling inspection is completed, the opening 15 is again locked in the state of being closed with the lid plate 30 and sealed. However, the destroyed initial sealing lock piece 22 is separated from the resin case 13 and has already lost its locking function. Therefore, the lock to the closed state is performed by the lock piece 32 for resealing. In this locking operation, the shaft part 34 is slid along the guide groove 20 so as to be positioned at the end opposite to the initial closed state, and the cover plate 30 is reversed from the initial closed state. The direction is changed and displaced so as to close the opening 15. Then, the reseal lock piece 32 comes into the opening 15, and during this time, as shown in FIG. 6, the locking claw 33 of the reseal lock piece 32 comes into contact with the receiving piece 25, and both Some elastic bending occurs. Then, after this state, when the cover plate 30 comes into contact with the cover plate receiving portion 21 and is in the re-closed state, the reseal lock piece 32 and the receiving piece 25 are elastically restored as shown in FIG. Then, the locking claw 33 is locked to the front end surface of the receiving piece 25, and the cover plate 30 is locked so that it cannot be displaced in the opening direction.
In this re-closed state, the lock piece 32 for re-sealing and the receiving piece 25 are locked inside the box body 10, so this lock cannot be released from the outside of the box body 10. Then, the sealing paper is pasted again at the joint between the outer peripheral edge of the cover plate 30 and the opening edge of the opening 15.
[0013]
As described above, according to the present embodiment, when the initial sealing lock piece 22 is destroyed and the lock is released, it is made clear that the lock is released by the trace of the destruction. The release is prevented. Moreover, since the re-seal lock piece 32 is provided separately from the initial seal lock piece 22, the lock / seal is released once, the circuit board is inspected, and then the lock / seal is performed again. Can be done.
Furthermore, since the lock by the re-seal lock piece 32 is performed inside the box body 10, it cannot be unlocked from the outside, and unauthorized lock / seal release is prevented.
Further, while the lock in the closed state is released, the cover plate 30 is kept in an integrated state with the box body 10 by fitting the shaft portion 34 into the guide groove 20, that is, the cover plate. Since 30 can be reversed without being detached from the box body 10, the operation up to the re-closing operation of the lid plate 30 is extremely smooth, and as a result, the inspection operation can be performed smoothly.
