[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a control box that stores a control board that controls game contents of a gaming machine (such as a pachinko machine), and relates to a control box that prevents fraud.
[0002]
[Prior art]
In a gaming machine (such as a pachinko machine), a control box provided with a control board for controlling the game content is provided with a control box so that the game content can be easily changed in order to always provide interest to the player. Is detachable.
Control elements such as a CPU and a ROM are arranged on the control board, and in particular, a ROM in which control software is recorded plays an important role. Therefore, in order to prevent such a game from being replaced by changing the ROM, a seal paper is stuck on the control box so that fraud cannot be easily performed.
[0003]
[Problems to be solved by the invention]
However, using a special liquid to remove the seal paper without damaging it, leaving no trace of the seal paper on it, and replacing it with an illegal ROM, and then applying the same seal paper for unauthorized modification Has been done.
Accordingly, there is a demand for a countermeasure that does not easily perform such an illegal act, and the present invention provides a control box that can solve such a problem.
[0004]
[Means for Solving the Problems]
The control box of the gaming machine according to claim 1 will be described based on an embodiment. The control box (1) is composed of a chassis body (10) and a case body (30).
A mounting opening (11) for forming opening windows (40a, 40b) is provided on the side of the control box, and an upper slit (18a) is provided in the mounting opening (11) of the case body, and a mounting opening ( 11) is formed with a lower slit (18b).
Further, sealing paper (15) is attached to the mounting opening (11) of the case body and the mounting opening (11) of the chassis body to cover the mounting opening (11).
The lid member (16B) has a pair of insertions in which a projection body (43a, 43b) is provided at a position corresponding to the opening window (40a, 40b) and a locking claw (22A, 22B) is formed at the tip. It is comprised with a body (17a, 17b).
Therefore, after sticking the sealing paper (15) on the mounting opening (11) of the chassis body (10) and the case body (30) which are overlapped, the inserts (17a, 17b) are inserted into the upper slit (18a) and the lower slit ( When inserted in 18b), the sealing paper (15) is pushed out by the protrusions (43a, 43b).
In such a control box, it is necessary to destroy the lid member (16B) in order to replace the “control element such as a ROM” mounted on the control board. However, since the sealing paper (15) is pushed out by the protrusions (43a, 43b) and is easily damaged, when the protrusions (43a, 43b) are cut, there are traces on the sealing paper (15). Since it remains, fraud can be prevented.

DETAILED DESCRIPTION OF THE INVENTION
A pachinko machine will be described as an example of a gaming machine. When a gaming ball wins a specific place, the pachinko machine generates a jackpot or the like that is advantageous to the player via a symbol display and pays out a large amount of prize balls. In order to control such game contents, a control board (not shown) on which a “control element such as a ROM” is mounted is fixed with a screw or the like in the control box 1 on the back of the pachinko machine. is there.
[0006]
FIG. 1 is a back view of a well-known pachinko machine. In the center of the back surface, the game balls won in a winning opening provided on the front side of the game board are collected, and each ball is separated into a winning ball processing device 62. A winning ball collecting basket 61 is provided. A control box 1 having a control board on which a control element for performing game processing such as a winning ball or a prize ball is mounted is arranged at the lower left of the winning ball assembly box 61, and a ball at the lower right is a ball. An interface board 80 for transmitting and receiving a processing signal such as a ball rental based on a signal from the lending machine 20 with the pachinko machine is installed.
[0007]
In addition, a storage tank 63 for storing game balls before being discharged is provided on the upper part of the pachinko machine, and the alignment is such that the game balls are aligned in two rows from the storage tank 63 and guided to the game ball discharge device 65. A fence 64 is installed. A ball leveling 66 for preventing the game balls from overlapping is suspended from the alignment rod 64 so as to be swingable. In addition, the game balls discharged from the game ball discharge device 65 flow out to the upper plate through the flow-down rod 67. Also, a terminal board 69 is attached to the upper right side of the pachinko machine, and a game ball launching device 91 is provided on the lower left side to launch game balls one by one.
[0008]
(First embodiment)
FIG. 2 is a perspective view of the control box 1, and the control box 1 includes a box-shaped chassis body 10 and a case body 30. 3 is a front view of the control box 1, and FIG. 4 is a cross-sectional view taken along line AA of FIG.
The chassis body 10 is made of a transparent synthetic resin in a square box shape having an opening. A concave mounting port 11 is formed at the center of the front surface 10a and the back surface 10b so as to be on the same surface when the case body 30 is mounted. A through-hole 12 for fixing the case body 30 via a screw is formed in the upper portion of the mounting opening 11, and a lid member 16 is provided with a space where almost half of the sealing paper 15 can be pasted. A lower slit 18b into which the lower insert 17b can be inserted is formed. Moreover, the protrusions 20 and 20 which attach the case body 30 are provided in the both ends of the front surface 10a and the back surface 10b.
[0009]
The lid member 16 is made of a transparent synthetic resin and is composed of a plate-shaped main body 16a, an upper insert 17a, and a lower insert 17b. The main body 16a is preferably sized to be mounted in the mounting opening 11 without a gap, and is used for inspection ( The upper insert 17a and the lower insert are inserted into the upper slit 18a and the lower slit 18b on the back surface side, and the cut windows 19 for allowing the lid member to be broken are formed at appropriate intervals. 17b protrudes. In addition, a locking claw 22 (saddle shape) is formed at the distal ends of the inserts 17a and 17b so as to face each other, and removal is prohibited when they are inserted into the upper slit 18a and the lower slit 18b. .
[0010]
The case body 30 is formed of a transparent synthetic resin so that each side surface becomes the same surface when attached to the chassis body 10 and the inside can be seen.
A fixing hole 31 is formed at a position corresponding to the through hole 12 at the center of the front surface 30a and the back surface 30b, and an upper slit 18a into which the upper insert 17a of the lid member 16 can be inserted. Is formed. In addition, the case body 30 is provided with a protruding plate 32, an insertion hole 33 is formed at a position corresponding to the protruding body 20 formed in the chassis body 10, and a cut window 34 is formed above the insertion hole 33 for inspection. At this time, the protruding plate 32 can be easily cut with a nipper or the like.
[0011]
Next, assembly of the control box 1 having the above-described configuration will be described with reference to FIG. 3 showing a front view and FIG. 4 showing cross sections AA.
First, the insertion hole 33 formed in the case body 30 is attached to the projecting body 20 of the chassis body 10. The insertion hole 33 can be easily mounted using the deflection of the protruding plate 32.
The case body 30 is fixed to the chassis body 10 by attaching the flat screw 24 to the fixing hole 31 and the through-hole 12, and using this flat screw 24 makes it difficult to remove the screw.
Next, after sticking the sealing paper 15 on the case body 30 and the chassis body 10 and on the flat screw 24, the upper insertion body 17a and the lower insertion body 17b of the lid member 16 are moved to the lower slit 18a and the lower insertion body 17b. Insert into the slit 18b. The main body 16a of the lid member 16 is mounted in the mounting opening 11 without a gap, and the locking claw 22 of the upper insertion body 17a locks the case body 30, and the locking claw 22 of the lower insertion body 17b locks the chassis body 10. Thus, the removal is impossible (see FIG. 4).
[0012]
The control box 1 assembled in this way can see the sealing paper 15 through the transparent lid member 16 and is fixed with the locking claws 22 in order to open the case body 30 (or the chassis body 10). Therefore, it becomes impossible unless the lid member 16 is destroyed, and thus fraud is difficult.
Further, in the control box 1, the chassis body 10 and the case body 30 are connected to each other by thermally melting the projecting body 20 with a hot metal rod or the like. Therefore, in order to open the case body 30, it is necessary to cut the protruding plate 32 through the cutting window 34 with a nipper or the like, or to cut the thermal coupling portion. Therefore, it becomes difficult to open the case body 30 illegally.
[0013]
Next, since the assembled control box 1 may check the “ROM etc.” that records the game contents, the operation at that time will be described.
In this inspection, first, the protruding plate 32 is cut by the nipper or the like through the cut window 34 so that the case body 30 and the chassis body 10 can be separated.
Next, the lid member 16 is broken by a nipper or the like, and this is performed through a cut window 19 provided for facilitating the breakage (cutting). That is, if the lid member 16 is flat, it is difficult to break (cut) with such a nipper or the like.
And if the screw 24 is pulled out after peeling the sealing paper 15, the chassis body 10 and the case body 30 can be separated and opened. Thereafter, the ROM is removed from the control board and inspected.
[0014]
Next, the assembly of the control box 1 after the inspection is completed will be described. First, the case body 30 is attached to the chassis body 10. And after fixing with the flat screw 24 similarly to the above, the new inspection sealing paper 15 is stuck over the case body 30 and the chassis body 10. FIG.
Then, holding the inspection lid member 16A (see FIG. 2) in which the cut window 19 is not formed in the main body 16b, the upper insert 17a and the lower insert 17b are inserted into the upper slit 18a and the lower slit 18b, respectively.
By inserting the inspection lid member 16A, the inspection sealing paper 15 can be confirmed through the transparent inspection lid member 16A. In addition, it is impossible to take out the “ROM etc.” because the locking claw (saddle type) 22 locks the case body 30 and the chassis body 10 so long as the inspection lid member 16 is not destroyed. Further, unlike the lid member 16, the inspection lid member 16 </ b> A is not formed with the cut window 19, so that it is more difficult to break.
[0015]
Since the control box 1 has the locking claws 22 formed on the inserts 17a and 17b of the lid member 16, once installed, the control box 1 is opened and "ROM etc." In addition, if the protrusion 20 is melted and bonded together, a trace when opened is left, which prevents fraud. Further, in the lid member 16 of the present invention, a cut window 19 is formed in the lid member 16 and a cut window 34 is formed in the protruding plate 32 so that the lid member 16 can be easily broken in consideration of inspection.
The projecting body 20 is formed in the chassis body 10 and the insertion hole 33 is formed in the case body 30. However, the projecting body 20 may be reversed, and the projecting body 20 is made of a synthetic resin that can be easily melted by heat. Other than that, the main body may be a metal or the like.
[0016]
(Second Embodiment)
The control box of the present embodiment will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and differences are described.
A pair of opening windows 40 a and 40 b are formed in the mounting opening 11 of the chassis body 10 with a through hole 12 fixed via a screw 24 interposed therebetween. The case body 30 is also formed with a pair of opening windows 41 a and 41 b with the fixing hole 31 sandwiched at a position corresponding to the through hole 12.
Further, as shown in FIG. 6 (A) (front view) and FIG. 6 (B) (side view), the lid member 16B has upper locking claws formed at the end portions of the upper insertion body 17a and the lower insertion body 17b. 22A and the lower locking claw 22B are formed in directions facing each other (the upper locking claw 22A is directed to the lower insertion body 17b and the lower locking claw 22B is directed to the upper insertion body 17a), and cut to facilitate inspection. A window 19 is formed. The lid member body 16a is provided with projections 43a and 43b corresponding to the opening windows 40a and 41a and the opening windows 40b and 41b.
The lid member 16C is mounted after inspection, and has the same configuration as the lid member 16B, but the cut window 19 is not formed. Reference numeral 50 denotes a control board on which a control element (not shown) such as a ROM is mounted, and is fixed to the chassis body 19 with screws.
[0017]
FIGS. 7A and 7B show cross sections when the components having the above-described configuration are assembled in the same manner as in the first embodiment. The sealing paper 15 includes the opening windows 40a and 41a and the opening windows 40b and 41b. At the location, the protrusions 43a and 43b provided on the main body 16a of the lid member 16B are attached by being pushed out (bent) as shown in FIG. 7, and the lid member 16B is fitted to the mounting opening 11 without a gap. The upper locking claw 22A locks the case body 30 and the lower locking claw 22B locks the chassis body 10 in a state of facing each other to prevent removal.
[0018]
Next, in order to open the control box, first, it is necessary to cut from the cut window 19 of the lid member 16B with a nipper or the like, and also to cut the protrusions 43a and 43b. However, since the sealing paper 15 is in contact with the protrusions 43a and 43b, if this action is performed, the sealing paper 15 is likely to be damaged.
Even if the lid member 16B can be cut without damaging the sealing paper 15, the case body 10 and the chassis body 30 are fixed with screws 24. Therefore, in order to remove the screw 24, it is necessary to remove the sealing paper 15 without damaging it or to remove the lid member 16B, but the former is difficult.
Therefore, the latter will be explained. If the separated upper lid member 16B is to be pulled out, the upper locking claw 22A attached to the separated lid member faces downward (in the direction of the lower insert 17b). In order to pull out the upper lid member 16B, it is necessary to move it upward, but the upper lid member 16B cannot be moved by hitting the upper edge 11a of the mounting opening 11, and eventually it is difficult to remove, If the cover member 16B is moved to remove it, the sealing paper 15 will be damaged. On the other hand, in the separated lower lid member 16B, it is necessary to move in the opposite direction to the upper lid member. However, since the lower lid member 16B is in contact with the lower edge 11b of the mounting opening 11, the removal is similarly performed. difficult.
As described above, even if the control box of this embodiment can cut the cover member 16B without damaging the sealing paper 15, the chassis body 10 and the case body 30 fixed with the screws 24 without damaging the sealing paper 15. Therefore, it is difficult to exchange “ROM” illegally without damaging the sealing paper 15 after all.
[0019]
【The invention's effect】
In the control box of the gaming machine according to the present invention, when the chassis body and the case body are combined, and the sealing paper is pasted on the mounting opening, and then the lid member formed with the locking claw is mounted, the sealing paper is pushed out by the protrusion. Since it is in a state of being easily damaged, if the protrusion is destroyed, the trace remains on the sealing paper, so that illegal acts can be prevented.
