Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing unauthorized removal of an electronic control board used in a pachinko game machine.
More specifically, in a pachinko gaming machine capable of displaying an electronic control game during a pachinko game developed in a game board, an unauthorized removal of an electronic control board mounted on the back side of the machine is prevented. It relates to a prevention device.

[0002]

2. Description of the Related Art In a pachinko machine or an arrangement ball machine, which is one of typical examples of this kind of pachinko game machine, various prize-winning devices and ball-entering devices as game parts are arranged on a game board set in the machine. On the other hand, in addition to the symbol display device and the electric winning device as electronic control parts, detection switches, electromagnetic solenoids, lamps, etc. are arranged, and during the pachinko game deployed in the game board, sound effects and decorations Many models having a game content that enables the display of an electronic control game including light are manufactured and provided for games. Regardless of the gaming machine, a genuine electronic control board (generally also referred to as a main board or gaming board) suitable for each electronic control game has software program contents designed and configured by the manufacturer. It is obliged to be used normally under the condition that the contents are the same and conform to strict tests at a testing institute, and are generally detachably mounted at a set position on the back side. The control board of each manufacturer is generally configured in the same form and size common to all models, and a label sticker including "company name, model name, etc." is attached to the same portion.

[0003] In an electronic control board used for a pachinko gaming machine, as an example of a countermeasure for preventing unauthorized alteration or change on the assumption that the electronic control board is normally used with proper control contents (software program contents), Some manufacturers of the base box that accommodates and protects the circuit board on which various electronic components (CPU, ROM, RAM, etc.) are mounted It is obliged to affix a seal stamp, which has been registered and approved, to prohibit and prevent the removal and replacement of circuit boards and the unauthorized modification and replacement of electronic components. However, such seals alone, for example, can be easily and easily peeled off and re-attached without damage to the seals, using readily available tools and chemicals, according to those who plan to commit fraud. As a result, the case cover is removed within a relatively short period of time, and the electronic components of the circuit board are replaced, so that it cannot be said that this is an appropriate and suitable countermeasure for preventing fraud. By the way, if a fraudster once peels off the seal stamp and puts it back on it, it is difficult for even the person in charge of the manufacturer or the manager of the hall to know whether there is fraud. .

[0004]

Therefore, recently, as a new example of measures for preventing unauthorized alteration of the electronic control board (replacement of ROM), (a) the tray section of the base box and the case cover section are required. Assemble using special screws and bosses that are newly developed for the purpose of fraud prevention and managed only by the manufacturer (dedicated person in charge). Then, in the official inspection of the gaming machine installed in the hall, when inspecting the electronic components of the electronic control board, the screws are destroyed and the case cover is removed, and after the inspection, new genuine screws and bosses are removed. (B) One time changeable use is possible in the opening area of required width formed in the case cover part of the base box. Regularly assemble the transparent window cover using special screws. Then, at the time of inspection of electronic components at the inspection of the government, the screw was destroyed and the window lid was removed,
A technique has been proposed in which a window cover is assembled face down using a new genuine screw after the inspection.

Therefore, according to the above-mentioned techniques (a) and (b), it is possible to prevent the case cover portion and the window cover of the base box in the control base from being illegally opened except at the time of checking the inspection. In the unlikely event of unauthorized opening, the evidence will be clearly visible and the presence or absence of fraud can be discerned, which is effective in preventing unauthorized exchange of ROM and is also useful for early detection of fraud. However, none of these technologies is a technology for preventing unauthorized exchange of the control platform itself, and therefore, a control platform employing these technologies can still be easily attached to and detached from the backside of the gaming machine. For this reason, a gaming machine manufactured by each manufacturer and equipped with a control base is shipped by the manufacturer until it is installed in the customer's hall, or after the closing of business in the hall, by a fraudulent person with detailed circumstances In some cases, the control base of the target gaming machine was replaced and installed with a fraudulently modified base of the same manufacturer, which was obtained and prepared through another route, and it was difficult to take appropriate preventive measures to cope with this. Incidentally, even if the gaming machine is disposed of by a specialized trader when the gaming machine is disposed of, it may be illegally modified and stored afterwards by the wrongdoer.

[0006]

[0016]

First Embodiment FIGS. 1 to 4 show an unauthorized removal prevention device according to a first embodiment of the present invention which is applied to the electronic control unit E mounted on a mechanism set board D. The tamper-proof device F of the first embodiment includes a tightening band 35 that can be mounted on the outer surface of the base box 15 in the electronic control device E in a lateral direction, and a stopper formed at a required position of the installation portion 30. And a tightening band 35 which is screwed into the stopper 39.
Is fixed to the installation part 30. The tightening band 35 is provided at both end portions of a band portion 36 of a required width formed in a concave band shape 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, Installation part 30 of the mechanism set board D
Is a transparent resin material in which the attachment portions 37 attached to the stoppers 39 are integrally formed.
7 are provided with through holes 38 through which the screws 41 are inserted.

The stopper 39 is located at a predetermined position outside the first lid member 22 and the second lid member 27, that is, the installation portion 30.
When the tightening band 35 is positioned in the base box 15 of the electronic control device E attached to the base plate, the through holes 38 of the attachment portions 37 are aligned with each other so that the screw 41 can be screwed into the small portion. It is formed into a boss having a required length and having a hole 40. Therefore, the tightening band 35 is mounted on the base box 15 at a predetermined position, and the screw 41 is screwed between the through hole 38 of each mounting portion 37 and the small hole 40 of the stopper 39 to thereby tighten the tightening band. Reference numeral 35 is fixed to the installation section 30 with the base box 15 tightened. As shown in FIG. 2, FIG. 3, and FIG. 4, holding pieces 20, 20 for holding the mounted tightening band 35 from above and below are extended on the see-through plate 19 of the cover body 17 in the lateral direction. In the present state, they are integrally protruded to prevent proper positioning and displacement of the mounted tightening band 35.

The screw 41 used in the tamper-proof device F of the embodiment is a commercially available screw-only type having a non-slack-removable structure, and can be screwed by a general tool such as a screwdriver. Although it is possible, the operation for removing the slack after being screwed is completely impossible. 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.
The head 45 of the screw 41 screwed into the through hole 38 and the small hole 40 of the stopper 39 is formed.
Are immersed in the recess 90 (FIG. 2).
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.

The screw 41 of the type exclusive for tightening as described above.
In the tamper-proof device F of the first embodiment, the tightening band 35 can be easily and easily attached to the electronic control device E attached to the installation portion 30 by using a normal tool. In this case, the screw 41 cannot be loosened to remove the tightening band 35, so that it is impossible for an ordinary person to open the base box 15 that covers and protects the control base 14. In addition, each flange 31 of the case body 16
As shown in FIG. 2, in a state where the electronic control device E is attached to the installation section 30, the electronic control devices E are set to extend outward from the corresponding stoppers 39 respectively. Accordingly, the locking member 32 temporarily attaching the base box 15 to the first lid member 22 and the second lid member 27 is removed, and the unauthorized removal prevention device F is set in the installation section 30.
If the electronic control device E is slid upward while being fixed to the bracket, as shown in FIG. 2, the left flange 31 holding the locking tool 32 interferes with the tightening band 35, and If the user tries to slide the electronic control unit E downward, the upper right flange 31 interferes with the tightening band 35, so that even in this case, the electronic control unit E cannot be removed.

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.
In the electronic control device E attached to the mechanism set board D, if the control base 14 covered and protected by the base box 15 is to be removed, the tightening band 35 is cut at an arbitrary position. 5 or, as shown in FIG. 5, the cover 17 of the base box 15 cannot be removed except for cutting the screw 41 screwed into the stopper 39 with a tool such as a gold saw. However, it is possible to remove the control board 14 by executing any of the above-mentioned means, but since the tightening band 35 or the stopper 39, which is a genuine part, is damaged, there is no evidence of unauthorized opening. Is clearly left and the presence or absence of fraud can be easily confirmed. In particular, the first cover member 22 in which the tightening band 35 and the stopper 39 are integrally formed.
And since the second lid member 27 and the like are genuine parts manufactured by the manufacturer of the pachinko gaming machine P, if an unauthorized person who cannot obtain the genuine parts properly is damaged, the fact of opening is hidden. I can't.

[0023]

When the tightening band 35 is positioned in the base box 15 of the electronic control device E attached to the base plate, the through holes 38 of the attachment portions 37 are aligned with each other so that the screw 41 can be screwed into the small portion. It is formed into a boss having a required length and having a hole 40. Therefore, the tightening band 35 is mounted on the base box 15 at a predetermined position, and the screw 41 is screwed between the through hole 38 of each mounting portion 37 and the small hole 40 of the stopper 39 to thereby tighten the tightening band. Reference numeral 35 is fixed to the installation section 30 with the base box 15 tightened. As shown in FIG. 2, FIG. 3, and FIG. 4, holding pieces 20, 20 for holding the mounted tightening band 35 from above and below are extended on the see-through plate 19 of the cover body 17 in the lateral direction. In the present state, they are integrally protruded to prevent proper positioning and displacement of the mounted tightening band 35.

The screw 41 used in the tamper-proof device F of the embodiment is a commercially available screw-only type having a non-slack-removable structure, and can be screwed by a general tool such as a screwdriver. Although it is possible, the operation for removing the slack after being screwed is completely impossible. 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.
