[0003] In an electronic control device used in a pachinko gaming machine, as an example of a countermeasure for preventing unauthorized alteration or change on the premise that the electronic control device is normally used with proper control contents (software program contents). In some cases, manufacturers of trays and case covers that screw together each other with regard to a base box that houses and protects a control board (also called a circuit board) on which various electronic components (CPU, ROM, RAM, etc.) are mounted. It is obliged to affix a seal stamp that has been registered and approved to the attachment matching part, and the prohibition and prevention of the detachment / replacement and replacement of the control board and the unauthorized remodeling and replacement of the electronic parts are prohibited. However, such seals alone, for example, can be easily and easily peeled off and re-attached without damage to the seals, using easily available tools and chemicals, according to the wrongdoer. As a result, the case cover is removed within a relatively short period of time, and the electronic components of the control board are replaced, so that it cannot be said that this is an appropriate and suitable countermeasure against fraud. By the way, in the case where an unauthorized person once peels off the seal stamp and puts it back to the original state, even if it is the person in charge of the manufacturer or the administrator of the hall side,
It is difficult to tell whether there is fraud.

First Embodiment FIGS. 2 to 5 show an unauthorized removal prevention device according to a first embodiment of the present invention which is applied to the electronic control device E mounted on a mechanism set board D. The device F for preventing unauthorized removal of the first embodiment has a tightening band 35 which can be mounted on the outer surface of the base box 15 in the electronic control device E in a lateral direction, and is formed by projecting at a required position of the installation portion 30. A boss-shaped stopper 39 having a small hole 40;
And a screw 41 for screwing the tightening band 35 into the mounting portion 30 by screwing into the small hole 40. The tightening band 35 is provided at both end portions of a band portion 36 having a required width formed in a concave band shape and tightly mounted on the outer surface of the cover body 17 and the outer side surface of the case body 16 in the base box 15. The attachment portions 37 attached to the stoppers 39 in the installation portion 30 of the mechanism set board D are transparent resin materials formed integrally with each other, and the screws 41 are attached to the attachment portions 37 at both ends. Each of the through holes 38 to be inserted is provided.

In the electronic control device E attached to the installation section 30, the stopper 39 is provided at a first mounting position 50 at a position above the vertical center of the base box 15 and at a second position at a position below the vertical center as appropriate. On the premise of the mounting position 51, when the tightening band 35 is positioned at the first mounting position 50, it is composed of a pair of bosses 52, 52 protruding at positions where the through holes 38 of the mounting portions 37 are aligned. It comprises a first set of stoppers 39A and a pair of bosses 53, 53 protruding at positions where the through holes 38 of each attachment portion 37 are aligned when the tightening band 35 is positioned at the second mounting position 51. And a second set of stoppers 39B. That is, the first set of stoppers 39A and the second set of
The set of stoppers 39B includes the first lid member 22 and the second lid member 22B.
On the outer surface of the lid member 27, the respective bosses 52, 53 are formed so as to protrude at a required interval in the vertical direction, and the small holes 40 are formed in the respective bosses 52, 53. Accordingly, the tightening band 35 is mounted on the first mounting position 50 of the base box 15, and the through holes 38 of the mounting portions 37 and the first set of the stoppers 3 are provided.
By screwing the screw 41 between each of the small holes 40 in 9A, the tightening band 35 is fixed to the installation portion 30 with the base box 15 tightened. In addition, tightening band 35
Is mounted on the second mounting position 51 of the base box 15, and each mounting portion 3 is mounted.
By screwing the screw 41 between the through hole 38 of No. 7 and each of the small holes 40 of the second set of fasteners 39B, the tightening band 35 is similarly fixed to the installation portion 30 with the base box 15 tightened. Is done. The see-through plate 19 of the cover body 17 includes
As shown in FIG. 2, FIG. 3 and FIG.
And the tightening band 3 mounted on the second mounting position 51
The holding pieces 20, 20 for holding the upper and lower members 5 from above and below are integrally protruded in a state of extending in the lateral direction.
Appropriate positioning and displacement of the tightening band 35 mounted on the 51 are prevented.

The screw 41 is a commercially available screw-only type having a non-loosening structure, and can be screwed by a general tool such as a screwdriver, but can be loosened after being screwed. It was designed to be impossible at all. Specifically, as shown in FIGS. 6 and 7, a main screw 43 formed in the same manner as a normal screw for screwing into the shaft portion 42, and the outer diameter is set to be appropriately small in a direction opposite to the main screw 43. A formed auxiliary screw 44 is formed.
In the auxiliary screw 44, the inclined surface 44a of the screw thread on the tightening side is formed to be steep with respect to the screwing direction of the main screw 43, and the inclined surface 44b of the screw thread on the slack side is formed by the inclined surface 44a.
It is formed with a gentler gradient than that. Therefore, when the screw 41 is screwed in, the screw can be tightened with substantially the same torque as a normal screw. However, when the screw 41 is loosened, the auxiliary screw 44 bites into the small hole 40 to increase the resistance, requiring a considerably large torque. It has become something.

A locking groove 4 formed on the top surface of the head 45
6 is a case where the screw 41 is a right-hand screw tightened by clockwise rotation, and the first engaging surface 47 with which a tip engaging portion of a tool (not shown) abuts during screwing operation is formed in the same manner as a normal screw. However, the second engaging surface 48 with which the engaging portion of the tool comes into contact during the loosening operation is formed in an inclined shape that becomes shallower toward the left side. Therefore, screwing
When performing the (right rotation in FIG. 7) operation, the engaging portion of the tool (not shown) and the first engaging surface 47 can be engaged to perform a suitable tightening operation. rotation)
When the operation is performed, the tool is disengaged from the locking groove 46 by the second engagement surface 48, and the loosening operation itself is impossible. Therefore, the screw 41
Is formed by an auxiliary screw 44 formed on the shaft portion 42 and a second engagement surface 48 in a locking groove 46 formed on the top surface of the head portion 45.
Although the screwing operation can be performed like a normal screw,
The loosening operation becomes completely impossible. The through-hole 38 is provided on the front side of the attachment portion 37 in the tightening band 35.
And a head 45 of a screw 41 screwed into the through hole 38 and the small hole 40 of the stopper 39.
Are immersed in the recess 60 (FIG. 5).
reference). That is, since the head 45 of the screw 41 does not protrude from the attachment portion 37, the head 45 cannot be loosened by being held by a tool such as a plier and forcibly rotated.

In the illegitimate removal prevention device F of the first embodiment using the screw 41 as described above, the fastening of the tightening band 35 to the electronic control device E attached to the installation portion 30 can be easily performed by a normal tool. Can be carried out, but the screw 41
It is impossible at all to remove the tightening band 35 by loosening. Each of the flanges 31 of the case body 16 is, as shown in FIG.
Are set to extend laterally from the corresponding stoppers 39A and 39B respectively. Therefore, if the tightening band 35 is temporarily mounted on the first mounting position 50,
If the electronic control unit E is to be slid upward by removing the locking tool 32 to which the base box 15 is attached in a state in which the locking tool 5 is tightened, as shown in FIG. 3
2 is held on the left side of the tightening band 35.
If the user tries to slide the electronic control device E downward, the upper right flange 31 is tightened by the tightening band 35.
Therefore, it is impossible to remove the electronic control unit E and even to slide the electronic control unit E. Further, in a state where the tightening band 35 is mounted on the second mounting position 51 and the base box 15 is tightened, the locking device 32 to which the base box 15 is attached is removed, and the electronic control device E is moved upward. 2, the lower right flange 31 holding the locking member 32 interferes with the tightening band 35 and slides the electronic control device E downward, as shown in FIG. given that,
Since the left flange 31 interferes with the tightening band 35,
Similarly, it is impossible to remove the electronic control unit E or even to slide the electronic control unit E.

Further, when the electronic control device E is mounted on the installation section 30, as shown in FIG. 2, the locking pieces 23, 23 of the first lid member 22 and the lower left of the second lid member 27 are provided. The screw 29 of the section is set in a positional relationship overlapping the electronic control device E. That is, the engaging portion 24 of the first lid member 22
And the hook 26 is released, and at the same time the screws 29 at the upper right and lower right of the second lid member 27 are removed, the locking pieces 23 are locked to the mechanism set board D. The electronic control unit E, the first lid member 22 and the second lid member 27 are integrally removed from the mechanism set panel D because the screw 29 at the lower left is screwed to the mechanism set panel D. Is also impossible.

Accordingly, the unauthorized removal prevention device F of the first embodiment is described.
If the electronic control device E mounted on the mechanism set board D is to be removed and the control base 14 protected by the electronic control device E or the base box 15 is to be removed, the tightening band 35 is removed. Other than cutting at an arbitrary position or cutting the screws 41 screwed into the stoppers 39A and 39B and the stoppers 39A and 39B with a tool such as a gold saw as shown in FIG. The device E itself cannot be removed or the cover 17 of the base box 15 cannot be removed. However, if any of the above means is executed, it is possible to remove the electronic control device E itself or the control base 14, but since the tightening band 35, the stoppers 39A, 39B and the screw 41 will be damaged. In addition, evidence of unauthorized removal or unauthorized opening remains clearly, and the presence or absence of fraud can be easily confirmed. In particular, since the first cover member 22 and the second cover member 27, etc. integrally formed with the tightening band 35 and the stopper 39 are genuine parts manufactured by the maker of the pachinko gaming machine P, the genuine parts are In the event that a fraudulent person who is not available to the public is damaged, the fact of removal or opening cannot be obliterated.

[0023]

Next, the first embodiment constructed as described above will be described.
The operation of the unauthorized removal prevention device for the electronic control device for pachinko gaming machines according to the embodiment will be described.

In the pachinko gaming machine P in which the tamper-proof device F of the first embodiment is implemented, in the manufacturing process of the maker, an electronic control in which the control base 14 is covered and protected for the installation portion 30 of the mechanism set board D in the manufacturing process. After the installation work of the device E is completed, the tightening band 35 in the unauthorized removal prevention device F is
The electronic control device E is positioned and set at the first mounting position 50 in the base box 15 so that the electronic control device E is tightly immobilized and held. That is, the band portion 36 of the tightening band 35 is positioned between the holding pieces 20, 20 at the first mounting position 50 protruding from the see-through plate 19 of the base box 15, and the mounting portions 37 of the tightening band 35 are transparent. Each of the small holes 40 of both the bosses 52, 52 in the hole 38 and the first set of fasteners 39A aligned with the through hole 38
By tightening the screw 41 with a normal tool, the tightening band 35 is firmly supported by the installation portion 30 in a tightening state in which the band portion 36 is tightly mounted on the base box 15.

The screw 41 in the unauthorized removal prevention device F
It is impossible to remove the tightening band 35 by loosening the screw 41 because the loosening operation cannot be performed with a normal tool. It is absolutely impossible to open and remove the internal control board 14. And, for example, the tightening band 3
According to a method of cutting the boss 52 at an arbitrary position or a method of cutting the bosses 52 or the bosses 52 and the screws 41, the electronic control device E itself can be removed and the base box 15 can be opened. And the first set of fasteners 39A and screws 41 cannot be restored to their original condition, so that evidence of unauthorized removal and unauthorized opening clearly remains,
It is impossible for a fraudster to implement such measures.
Therefore, the pachinko gaming machine P to which the unauthorized removal prevention device F of the embodiment is attached is properly transported from the maker factory at an appropriate time, for example, during transportation until being installed in a customer's hall,
After installation in a hall, etc., illegal acts such as unauthorized replacement of the electronic control device E itself, removal of the control board 14 housed and protected in the base box 15, replacement of ROM, and replacement with a board that has been illegally remodeled are preferable. Can be prevented.

In the inspection of the gaming machine P installed in the hall by the government, any one of the above-mentioned methods or the above-mentioned method is selected and executed, and the cover 17 of the base box 15 is removed to control. The required inspection is performed by exposing the base 14. At this time, for example, when the band portion 36 of the tightening band 35 is cut at an appropriate position, each attachment portion 37 is fixed to the bosses 52, 52 of the first set of fasteners 39A with screws 41. Therefore, the cut tightening band 35 itself is still attached to the first mounting position 50. In one method, that is, when the boss 52 or the boss 52 and the screw 41 are cut, the tightening band 35 is removed from the installation portion 30. However, since the boss 52 itself hardly remains, the screw 41 is removed again. It becomes impossible to screw in.

Therefore, in the tamper-proofing device F of the present embodiment, after the statutory inspection of the government, the new tightening band 35 and the screw 41 are separately prepared, and the new tightening band 35 is mounted on the second hooking device. By positioning and setting at the position 51 and fixing it to the second set of stoppers 39B,
The electronic control device E having the cover of the control base 14 protected is tightened to be immobilized and held. That is, the base box 15
Of the second mounting position 51 projecting from the see-through plate 19 of FIG.
The band portion 36 of the new tightening band 35 is positioned between 0, 20 and the through hole 38 of each attaching portion 37 of the tightening band 35 is positioned.
Between the small holes 40 of both bosses 53, 53 in the second set of fasteners 39B aligned with the through holes 38.
1 is tightened with an ordinary tool to tighten the tightening band 35.
Is fixed to the installation section 30 in a tightened state in which the band section 36 is tightly mounted on the base box 15.

The screw 41 in the unauthorized removal prevention device F
As described above, since the loosening operation cannot be performed with a normal tool at all, the screw 41 is loosened to remove the tightening band 35, and the electronic control device E itself is removed or the base box 15 is removed. It is absolutely impossible to open and remove the internal control board 14. Therefore, it is preferable to perform an illegal exchange such as an illegal exchange of the electronic control device E itself, a removal of the control base 14 housed and protected in the base box 15, an exchange of the ROM, and an exchange with an illegally remodeled base after the government inspection. Can be prevented. According to the above-mentioned method or the above-mentioned method, the electronic control unit E itself is removed or the base 15 is removed.
However, since the damaged tightening band 35, the second set of fasteners 39B, the screws 41, and the like cannot be returned to their original state, traces of unauthorized exchange and opening are clearly left, and such an unauthorized person can use such a device. Even if the means is implemented, the presence or absence of the fraud can be easily identified.

Further, according to the tamper-proofing device F of the first embodiment, at the time of shipment from the manufacturer, the tightening band 35 is mounted on the first mounting position 50 to tighten the electronic control device E, and the pachinko game machine is provided. When the government inspection of P is carried out, a new tightening band 35 is mounted on the second mounting position 51 to tighten the electronic control device E.
The presence or absence of an inspection on the control board 14 of the pachinko gaming machine P can be easily grasped.

[0030]
