DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device provided in a game machine such as a pachinko machine and a slot machine.

[0002]

2. Description of the Related Art A gaming machine such as a pachinko machine has a built-in control device in which control elements such as a ROM and a CPU are provided on an internal board. Since the control device controls the operation of the gaming machine, the control element may be improperly replaced or improperly modified. Therefore, in order to prevent such misconduct, the applicant has proposed a screw holding device which is easily connected to the edge of the upper cover of the control device from the upper cover through a cutting portion and holds a one-way type screw. An invention of a control device provided with a plurality of units is provided. According to this, once screwed to the lower cover with a one-way type screw, the screw cannot be removed, and the upper and lower covers cannot be separated unless the screw holder is cut off from the upper cover. When the upper cover is removed, a trace of the cutting remains on the cut portion, and an unauthorized replacement or the like can be easily found. Therefore, it is possible to prevent fraud.
It should be noted that the provision of a plurality of screw holders requires the upper cover to be removed for legitimate purposes, such as checking at the police station in charge, so the upper cover can be attached even after such a check, and the screw holding This is because the parts are used in order.

[0003]

However, when the upper cover is repeatedly removed and attached for the above-mentioned regular purpose and only one screw holding portion is removed at the end, if the screw holding portion is screwed with the screw holding portion, In this case, care must be taken to prevent accidental screwing in, since it will not be possible to attach after removal. However, since the plurality of screw holding portions are all in the same form, there is a possibility that the screw holding portions may be inadvertently screwed in without being aware of the last. Therefore, even if it becomes necessary to immediately remove it, it cannot be dealt with.
Also, since it is difficult to distinguish by the same form of the screw holding part,
The last screw holding part may be used first even though other screw holding parts are unused. The same can be said when the last holding unit is used. In other words, in the screwed state using the last screw holding part, if this is removed, it will not be possible to attach it, so care must be taken not to cut it carelessly, but all the cut parts are on the upper cover side Since they are formed in the same form, they are completely cut off, making subsequent use impossible.

Therefore, the invention according to claim 1 provides a control device for a gaming machine that can effectively prevent careless use and cutting of the last screw holding portion and can carefully use the last screw holding portion. It is intended to do so.

[0005]

To achieve the above object, according to the first aspect of the present invention, the last one of the plurality of screw holding portions is distinguished from other screw holding portions. An identification means is provided. or,
According to the second aspect of the present invention, in addition to the object of the first aspect, in order to easily configure an identification means for preventing an inadvertent use of the last screw holding portion, the identification means is provided at least with the screw. The seal including the head is attached to the last screw holding portion. Further, in addition to the object of the first or second aspect, the invention described in claim 3 is to simplify the identification means for preventing inadvertent cutting after using the last screw holding portion. The identification means has a configuration in which the cutting section is provided at a location different from the other screw holding section.

Further, a screw insertion hole 17 is formed in a partition plate 16 formed at the center of the inside of each screw holding portion 13, and a screw insertion hole 1 is provided at the back of the screw insertion hole 17.
An elastic piece 18 is formed so as to surround 7. Further, in each screw holding portion 13, a wood screw 19 is gripped by the elastic piece 18 in a state of being inserted into the screw insertion hole 17 by about half.
The wood screw 19 is a so-called one-way type. When a minus screwdriver is pressed against the head and turned clockwise, the wood screw 19 turns clockwise with the rotation, but when the screwdriver is turned counterclockwise, The driver slips on the head and does not rotate.

However, in the upper fixed wings 12, 12, the right side is from the bottom and the left side is the fourth screw holding part 1 counted from the top.
Reference numerals 3 and 13 denote screw insertion holes 17, elastic pieces 18, and wood screws 19.
Are the same as those of the other three screw holding portions 13,
There is no connection by the cutting portion 15, and it is formed integrally with the upper fixed blade 12 as shown in FIG. Also, the upper fixed wings 12, 1
On the surface of No. 2, a serial number is formed for each of the screw holding portions 13, 13..., But the upper surface of the fourth screw holding portion 13, 13 is formed in a slightly lower concave portion 20. Then, seals 21 and 21 assigned number 4 are respectively attached to the recesses 20 and 20 so as to cover the head of the wood screw 19 in a normal state. Further, adjacent to the fourth screw holding portions 13, cylindrical screwing portions 23, 23 through which ordinary wood screws 22, 22 are inserted are integrally formed.
Reference numerals 24, 24 denote guard plates as protection members integrally formed on the front side of the upper fixed wings 12, 12, further outside the outermost screw holding portion 13 exposing the cut portions 15, 15, respectively. Each of the upper wings 12 is erected perpendicularly to the upper wing 12 and has substantially the same width as the upper wing 12, and also extends integrally with the upper cover 7 to a height corresponding to the upper surface thereof.
Engagement pieces 25, 25 each having a tip formed in a fuzzy shape are protruded from the upper end edges on the back side of the upper fixed wings 12, 12, respectively.

On the other hand, as shown in FIGS. 4 and 5, the lower cover 8 is formed in the same rectangular shape as the upper cover 7, and lower fixed blades 26, 26 are continuously provided on both sides. At the bottom of each lower fixed wing 26, mounting tabs 27, 27... 28 into which wood screws 19 and 22 can be screwed are respectively provided at positions corresponding to the screw holding portion 13 and the screwing portion 23 of the upper cover 7. The mounting tabs 27 corresponding to the first to third screw holding portions 13 are provided with ribs 29, 29,... Which are radially formed, and each rib 29 is a set of upper and lower covers 7, 8. In the attached state, each of the screw holding portions 13 is prevented from rotating by fitting into a groove (not shown) formed at the lower end of the corresponding screw holding portion 13. The mounting tab 27 corresponding to the fourth screw holding portion 13 is located in a through hole 30 formed in the bottom surface of the lower fixed wing 26 as shown in FIG. It is connected only by cutting portions 31, 31... In addition, 32, 32 is formed on the upper end edge of each lower fixed wing 26, 26, and the engagement piece 2 of the upper cover 7
Reference numerals 5 and 25 denote engagement recesses that can be locked.

In the control device 3 configured as described above, the upper cover 7 is superimposed on the lower cover 8 so that the upper fixed blades 12, 12 coincide with the lower fixed blades 26, 26. 25 are engaged with the engaging recesses 32, 32, and the wood screw 19 is inserted between the uppermost (first) screw holding portion 13 on the left side and the lowermost (first) screw holding portion 13 on the right side. Is screwed into the mounting tab 27 of the lower cover 8. At the same time, the wood screws 22 are also screwed into the left and right screwing portions 23 and 23 and screwed to the mounting tabs 28 of the lower cover 8. Then, as shown in FIG. 5, one left and right screw holding portions 13, 13 screwed by the wood screws 19, 19, the mounting tabs 27, 27, and the right and left screwing portions 23 screwed by the wood screws 22, 22. , 23 and the mounting tabs 28, 28, the upper cover 7 is assembled to the lower cover 8, and the board 5 is covered by the upper cover 7 without forming a gap. Therefore, in this state, the ordinary wood screw 22 can be removed, but the one-way wood screw 19 cannot be rotated in the opposite direction (counterclockwise) to the screwed state. Cannot be released.

However, when the upper cover 7 is to be removed in order to check the contents of the control element 6 installed on the board 5 for regular purposes, the ordinary wood screw 22 is removed, and the mounting tab 27 is removed. Left and right screw holding portions 13 screwed,
13 is cut with a tool such as a nipper,
By separating the screw holding portions 13 from the upper cover 7, the upper and lower covers 7, 8 can be separated.
On the other hand, when assembling the upper cover 7 again after the separation, the screw holders 13, 13 at the next stage (second) of the screw holder 13 screwed first may be screwed with the wood screws 19 in the same manner as described above. . Therefore, in this case, such separation and assembly of the upper and lower covers 7 and 8 can be repeated three times.

As described above, in this embodiment, in order to separate the upper and lower covers 7 and 8, the cutting portion 15 is cut and the screw holding portion 13 screwed to the mounting tab 27 of the lower cover 8 is moved to the upper cover. Since the upper cover 7 must be separated from the cover 7, if the upper cover 7 is removed improperly, a trace is always left. Therefore, it is possible to easily detect a fraudulent activity and to prevent the fraudulent activity. In particular, in the fourth screw holding unit 13, the head of the wood screw 19 is normally covered with the seal 21 to distinguish it from the others, so that the screw holding unit 1
When using No. 3, the seal 21 needs to be peeled off. Therefore, by giving this procedure, the use of the fourth, that is, the last, screw holding portion 13 can be reliably recognized, and careful use can be encouraged. In addition, due to the procedure for peeling off the seal 21, it is unlikely that any one of the first to third screw holding portions 13 is erroneously used irrespective of remaining. Similarly, in the fourth screw holding portion 13,
Unlike the other screw holding portions 13, the cutting portion 31 is located on the back side of the lower cover 8, so that it is possible to reliably recognize the last screw holding portion 13 by this difference in location. Therefore, after using the fourth screw holding portion 13,
The disconnection is carefully judged, and the situation of inadvertent disconnection does not occur.

The upper fixed wing 12 has guard plates 24 and 2.
Since each of the uprights 4 is erected, the upper surface of the upper fixed wing 12 is protected, and even if the control device 3 is dropped, there is no possibility that an object directly hits the cutting portion 15. Therefore, accidental cutting of the cutting section 15 causes the screw holding section 13
Can be effectively prevented from becoming unusable. Further, in the above-described embodiment, the screw attachment portion 23 is provided in addition to the screw holding portion 13 so that the upper and lower covers 7 and 8 can be assembled with the ordinary wood screws 22. It takes time to remove the wood screw 22 without fail. Therefore,
It becomes impossible to remove the upper cover 7 in a short time, and it is possible to preferably prevent improper behavior that can occur in a short time.

In the above-described embodiment, the location of the seal 21 or the cutting portion 31 is changed as the identification means. However, only the last screw holding portion is colored or the shape is changed (for example, The last screw holding portion may be distinguished by making a round tube shape and a square tube shape, changing the number of ribs, or the like. Also, the guard plate 24 can be provided upright on the entire periphery of the upper fixed blade 12 or provided for each screw holding portion 13. Further, the number of the threaded portions 23 of the ordinary wood screws 22 may be appropriately increased or decreased, for example, two screws may be provided on the left and right.

[0015]

According to the first aspect of the present invention, since the identification means can surely recognize the last screw holding portion, careless use or cutting of the last remaining screw holding portion can be performed. Can be effectively prevented and the last screw retainer can be carefully utilized. In addition, it is possible to prevent erroneous use in which the last screw holding portion is used first even though the other screw holding portions are unused. According to the second aspect of the present invention, in addition to the effect of the first aspect, the identification means is a seal attached to the last screw holding section, so that the last screw holding section is inadvertently used. Can be simply configured. Further, in the invention according to claim 3, in addition to the effect of claim 1 or 2, the cutting section is provided at a different place from the other screw holding section, so that the last screw holding section is used. The identification means for effectively preventing the inadvertent disconnection can be simply configured.
