However, in the lock mechanism, it is difficult to prevent unauthorized replacement of the control board for the gaming machine because it is possible to easily open the storage case without hesitating to leave no trace of unauthorized opening. .
Therefore, it may be difficult to cut by reinforcing the part to be cut by increasing the thickness of the part to be cut, thereby prolonging the time for illegal work, but there is a dilemma that makes it difficult to perform the cutting work at the time of regular opening.

  An object of the present invention is to provide a storage case for a control board for a gaming machine that can firmly reinforce a planned cutting portion and can easily perform a cutting operation on the planned cutting portion.

In order to achieve the above object, according to the first aspect of the present invention, an insertion hole is provided in a scheduled cutting portion of the lock mechanism that is cut when the storage case is opened, and a reinforcing member is detachably attached to the insertion hole by screwing or press fitting. It inserts in the above and reinforces the said cutting scheduled part. Therefore, it is difficult to cut the planned cutting portion in a state where the reinforcing member is inserted, and it takes time and effort as a whole to remove the reinforcing member and cut the planned cutting portion. Become. Even if the planned cutting portion is reinforced in this way, it is easy to cut the planned cutting portion if the reinforcing member is removed, so that it is possible to prevent the cutting work from taking a long time during regular opening.

  Hereinafter, first and second embodiments in which the present invention is embodied in a storage case for a control board for a pachinko machine will be described in detail with reference to the drawings. 1 to 5 show the storage case of the first embodiment, and FIGS. 6 and 7 show the storage case of the second embodiment.

(First embodiment)
FIG. 1 is a plan view of the storage case, and FIG. 2 is a side view of the storage case. As shown in these drawings, the storage case includes a cover body 16 having a rectangular shape in plan view, and a base body 12 having a rectangular shape in plan view that is assembled to the cover body 16 and defines the storage space 11 with the cover body 16. It is composed of The storage case is attached to a pachinko machine body (not shown) with a base body 12. A control board 50 is accommodated in the accommodation space 11. The control board 50 is formed by mounting a plurality of electrical / electronic components such as a CPU, a ROM, and a RAM on a printed circuit board, and controls the operation of the pachinko machine, specifically, controls related to a big hit lottery and a prize ball payout. Is for.

  3 and 4 are views showing a state in the middle of the accommodation space 11 being opened or closed. As shown in these drawings, guide protrusions 16a and 16b are formed on the cover body 16 on the two long sides (upper and lower sides in FIG. 3) side so as to extend along the sides. On the two long sides (upper and lower sides in FIG. 3) of the base body 12, guide recesses 12a and 12b are formed so as to extend along the sides. The cover body 16 and the base body 12 can be relatively moved only by sliding movement in the direction of the arrow in the figure by guiding the guide convex portions 16a and 16b to the guide concave portions 12a and 12b. It has become.

  For example, when the cover body 16 is slid in the left direction of the arrow with respect to the base body 12 from the state shown in FIGS. 3 and 4, the cover body 16 is completely assembled to the base body 12 and shown in FIGS. In this state, the accommodating space 11 is completely closed. On the contrary, when the cover body 16 is slid in the arrow right direction with respect to the base body 12 from this assembled state, the assembled state of the cover body 16 and the base body 12 is released, and the accommodation space 11 is gradually opened. The Rukoto.

  Here, simply by slidingly engaging the cover body 16 and the base body 12, the accommodation space 11 is easily opened. Therefore, the relative sliding movement is restricted in the storage case so that the storage space 11 is not easily opened, in other words, the cover body 16 and the base body 12 in the assembled state do not easily slide relative to each other. A lock mechanism 20 for locking is provided. Note that a plurality (four in this embodiment) of locking mechanisms 20 are provided, and the storage space 11 can be opened and closed a plurality of times. Hereinafter, the lock mechanism 20 will be described in detail.

  As shown in FIGS. 3 and 4, a plurality of (four in this embodiment) bases are provided in a portion located on one short side (the short side on the left side in FIG. 3) on the outer peripheral edge of the base body 12. The body side connection part 22 protrudes at predetermined intervals along the short side. A base body side cylindrical portion 24 as a second cylindrical portion is provided at the tip of each base body side connecting portion 22. A base body side lock hole 32 as a second lock hole is provided at the center of each base body side cylinder portion 24. The base body side lock hole 32 has a bottomed shape. A female screw surface is formed on the inner surface of the base body side lock hole 32 (not shown).

  A plurality (four in this embodiment) of cover body side connecting portions 26 are provided along the short side at a portion located on one short side (the left short side in FIG. 3) side of the outer peripheral edge of the cover body 16. Projecting at predetermined intervals. At the tip of each cover body side connecting portion 26, a cover body side cylinder portion 28 as a first cylinder portion is provided. A cover body side lock hole 34 serving as a first lock hole is provided in the center of each cover body side cylinder section 28. A female screw surface is formed on the inner surface of the cover body side lock hole 34 (not shown).

  5 is a cross-sectional view taken along line 1-1 of FIG. 1. As shown in FIG. 5, the base body side cylinder portion 24 and the cover body side cylinder portion 28 are in the assembled state of the base body 12 and the cover body 16. They are in a positional relationship where they overlap each other to form a single column. In this assembled state, the cover body side lock hole 34 and the base body side lock hole 32 have the same center axis and the inner space is continuous.

  Here, when it is desired to lock the relative sliding movement between the base body 12 and the cover body 16 in the assembled state, one lock mechanism 20 is caused to function. That is, in the lock mechanism 20, the one-way screw 30 as a shaft-like lock member is inserted from the cover body side lock hole 34 and is screwed until the insertion end side reaches the base body side lock hole 32. As described above, the one-way screw 30 is inserted and disposed across the cover body side lock hole 34 and the base body side lock hole 32, whereby the axial displacement direction between the base body side cylinder portion 24 and the cover body side cylinder portion 28 (FIG. 5). Relative movement in the right and left direction) is hindered by the interposition of the one-way screw 30. Therefore, the base body side cylinder part 24 and the cover body side cylinder part 28 are mutually restrained so as not to move relative to each other in the axial displacement direction. As a result, the base body 12 and the cover body 16 cannot move relative to each other in the direction of opening the accommodation space 11. It will be fixed to.

  Since the one-way screw 30 can be screwed only in one direction when the storage case is locked, the one-way screw 30 is not pulled out from the cover body side lock hole 34 and the locked state is not released. Further, since the base body side lock hole 32 is bottomed, the one-way screw 30 is not pulled out from the base body side lock hole 32 side and the locked state is not released.

  Next, when the locked state of the base body 12 and the cover body 16 is released, the cover body side connecting portion 26 (scheduled cutting portion) is used with a tool such as a nipper for the lock mechanism 20 that exhibits the locking ability. The cover body side cylinder portion 28 is separated from the cover body 16 by cutting. Therefore, the relative sliding movement between the cover body 16 and the base body 12 is not hindered by the one-way screw 30 and the accommodation space 11 can be opened.

  In addition, when the accommodation space 11 is closed again and the cover body 16 and the base body 12 are locked, another lock mechanism 20 (the lock mechanism 20 in which the cover body side connecting portion 26 is not cut) is used. .

  Now, as shown in FIGS. 1 and 2, in the storage case of the present embodiment, bolt holes 42 as insertion holes are respectively provided through the cover body side connecting portions 26 of the lock mechanisms 20. Each bolt hole 42 is arranged in each cover body side connecting portion 26 so that the central axis exists on the plane S including the cut surface formed at the time of cutting described above. Metal bolts 40 as reinforcing members are respectively screwed into the bolt holes 42. In addition, for the cover body side connecting portion 26 surrounded on both sides by the adjacent cover body side connecting portion 26, the operation of inserting the bolt 40 into the cover body side connecting portion 26 (bolt hole 42) is performed. May be hindered. Therefore, in this embodiment, by setting the length L of the bolt 40 to be smaller than the arrangement interval W of the cover body side connecting portion 26, the bolt 40 can be inserted between the adjacent cover body side connecting portions 26. is there.

Thus, it is difficult to cut the cover body side connecting portion 26 in which the bolt 40 is screwed into the bolt hole 42 with a normal tool. This is because the bolt 40 reinforces the cover body side connecting portion 26 and is strong against cutting, and even if it is forcibly cut in this state, the bolt 40 must be cut vertically along the central axis. In other words, for example, the work is more difficult than cutting the bolt 40 sideways.

  Therefore, when opening the storage case, after removing the bolt 40 from the cover body side connecting portion 26, the bolt hole 42 portion of the cover body side connecting portion 26 is cut with a tool. The cover body side connecting portion 26 from which the bolt 40 has been removed is exposed to the weakness due to the thinning due to the formation of the bolt hole 42, and is thus easily cut.

  As described above, according to the present embodiment, it is difficult to cut the cover body side connecting portion 26 in a state where the bolt 40 is inserted, and the entire work is required to remove the bolt 40 and cut the cover body side connecting portion 26. It is effective in preventing fraudulent acts. Even if the cover body side connecting portion 26 is reinforced in this way, it is easy to cut the cover body side connecting portion 26 if the bolts 40 are removed, so that it is possible to prevent the cutting work during regular opening from taking time.

(Second Embodiment)
In the present embodiment, the bolt 40 is shared among the plurality of lock mechanisms 20. That is, as shown in FIGS. 6 and 7, the plurality of locking mechanisms 20 are arranged such that the central axes of the bolt holes 42 are the same. As the bolt 40, a headless one (in other words, a portion having no protruding portion from the screw portion) is used. Further, the length L of the bolt 40 is longer than the arrangement interval W of the cover body side connecting portion 26.

  When the cover body side connecting portion 26 is cut in order to open the storage case in the locked state, the bolt of the cover body side connecting portion 26 adjacent to the cover body side connecting portion 26 is cut from the bolt hole 42 of the cover body side connecting portion 26 to be cut. Screw the bolt 40 into the hole 42. As a result, the bolt hole 42 of the cover body side connecting portion 26 to be cut is emptied, and the bolt 40 is screwed into the bolt hole 42 of the adjacent cover body side connecting portion 26 to be cut when the storage case is opened next time. Let them enter.

  In this way, by using the bolt 40 between the plurality of lock mechanisms 20, the number of parts can be reduced, and simultaneously with the work of removing the bolt 40 from the lock mechanism 20 to be cut, the next cutting is performed. The operation of screwing the bolt 40 into the target lock mechanism 20 can be performed, and the labor for the operation can be greatly reduced.

  The present invention is not limited to the first and second embodiments described above, and can be implemented in various modes, for example, using a known spring pin as a lock member or using a press-fit pin as a reinforcing member.

Further, the bolt hole 42 and the bolt 40 may be deleted from the cover body side connecting portion 26 and the base body side connecting portion 22 may be provided with a bolt hole and a bolt. In this case, the base body side cylinder portion 24 is the first cylinder portion, the base body side lock hole 32 is the first lock hole, the cover body side cylinder portion 28 is the second cylinder portion, and the cover body side lock hole 34 is the second lock hole. The base body side connecting part 22 can be grasped as the part to be cut.
Furthermore, the present invention may be applied to a storage case of a control board in a slot machine called a so-called pachislot machine.

When describing the technical idea that can be grasped from the above embodiment, the insertion hole is arranged such that a central axis exists on a plane including a cut surface formed at the time of cutting in the planned cutting portion. A storage case for a control board for a gaming machine according to claim 1 . In this way, if the cutting portion is to be cut with the reinforcing member inserted, the reinforcing member must be cut vertically along the central axis, for example, the reinforcing member is cut horizontally. More difficult work.
