Description

  The present invention relates to an anti-fraud structure for gaming machines.

  A gaming machine such as a pachinko machine is provided with a circuit board on which a large number of electronic components such as an MPU, a ROM, and a RAM constituting a microcomputer are mounted as a control device for controlling a gaming operation. These circuit boards are housed in a board case. Generally, the board case accommodates the circuit board by assembling a lid member that covers the front side of the circuit board and a bottom member that covers the back side of the circuit board.

By the way, in the gaming machine, there is a risk that an illegal act of executing a game different from the regular gaming performance such as making it easy to place a prize ball by exchanging electronic components such as ROM of the circuit board.
Therefore, in the conventional gaming machine, for the purpose of detecting fraud and preventing fraud, unique identification information is output wirelessly across a plurality of members constituting the circuit board case containing the circuit board. A sheet-like IC tag is attached (for example, see Patent Document 1). According to this, the IC tag is destroyed when the substrate case is opened to illegally replace the ROM or the like, and the identification information is not output when the IC tag is destroyed.

Patent No. 4042116

However, in the conventional anti-fraud structure, when the substrate case is opened, the IC tag may be peeled off without being destroyed by the adhesive or the adhesive solution used to peel the grip of the golf club. According to this, since the substrate case can be closed and the IC tag can be pasted again after illegally replacing the ROM or the like, it is difficult to find and prevent fraud.
Therefore, the present invention has been made with the object of providing an anti-fraud structure for a gaming machine capable of reliably detecting and preventing fraudulent actions by reliably destroying an IC tag when the substrate case is opened. .

Cover the gap between the insertion hole and the small connector.

  The upper wall portion and the lower wall portion of the peripheral wall 16 of the lid member 1a have a plurality of engaging portions 152 on their inner surfaces that can be engaged with the engaging claws 101 of the bottom member 1b. Is provided. The engaging portion 152 allows the L-shaped bent tip of the locking claw 101 to be fitted in the lateral direction.

Of the left and right side wall portions forming the peripheral wall 16 of the lid member 1a, the left side wall portion 17 (corresponding to the vertical wall portion of claim 1) corresponding to the left end 11 of the bottom member 1b is connected to the bottom member 1b. A pair of upper and lower rectangular cylindrical fitting holes 171 that can be fitted into the protruding pieces 102 at the left end 11 are provided.
A pair of upper and lower bosses 154 corresponding to the caulking boss 103 at the right end of the bottom member 1b are formed on the right side wall of the lid member 1a.

  In order to assemble the lid member 1a and the bottom member 1b constituting the substrate case 1, first, the lid member 1a is opposed to the left side and the bottom member 1b is shifted to the right side in the front-back direction, and the peripheral wall 16 of the lid member 1a The upper and lower wall portions and the upper and lower end edges of the bottom member 1b are brought into contact with each other in the facing direction (the direction of arrow T in FIG. 3). At this time, the engaging claws 101 at the upper and lower end edges of the bottom member 1b are positioned between the engaging portions 152 of the upper and lower wall portions of the lid member 1a, and the protruding pieces 102 of the bottom member 1b. The lid member 1 and the bottom member 1b are combined so as to face each fitting hole 171 of the lid member 1a.

Next, the lid member 1a and the bottom member 1b are moved relative to each other in the left-right lateral direction (the direction of arrow S in FIG. 3) along the wall surface of the bottom wall portion 10 of the bottom member 1b. 101 is fitted and locked to each engaging portion 152 of the lid member 1a, each protruding piece 102 of the bottom member 1b is fitted into each fitting hole 171 of the lid member 1a, and the inner surface of the left side wall portion 17 of the lid member 1a. The outer surface 120 of the standing wall 12 at the left end 11 of the bottom member 1b is brought into contact with 170, and the bosses 154 for caulking of the lid member 1a and the bosses 103 of the bottom member 1b are overlapped.
Then, both the bosses 154 and 103 are caulked and fixed by the caulking members 180 press-fitted into the both bosses 154 and 103, whereby the lid member 1a and the bottom member 1b are assembled and fixed.

  As shown in FIGS. 3 to 7, when the lid member 1a and the bottom member 1b are assembled, the inner surface 170 of the left side wall portion 17 of the lid member 1a to be abutted and the outer surface 120 of the upright wall 12 of the bottom member 1b. While sandwiching the sheet-like IC tag 2, both surfaces of the IC tag 2 are attached to the inner surface 170 of the left wall portion 17 and the outer surface 120 of the standing wall 12.

The IC tag 2 is a conventionally known one and will be outlined. As shown in FIG. 5, an IC chip portion 21 and an antenna portion 22 are mounted on a square sheet member 20 made of a thin synthetic resin such as paper or polyester. The identification number (unique ID) stored in the IC chip unit 21, the main control board management number (the number written on the sticker attached to the surface of the lid member 1 a of the board case 1), the manufacturer name, and the model name Such information can be read.
The sheet member 20 has a fragility that breaks when an abnormal tensile force that is not normal handling is applied. The IC chip portion 21 is provided at the center of the sheet member 20. The antenna portions 22 and 22 electrically connected to the IC chip portion 21 are provided on a diagonal line connecting the two corner angles of the IC chip portion 21 and the sheet member 20.
The IC tag 2 is broken in such a manner that the IC chip portion 21 and the antenna portion 22 are broken by the breakage of the sheet member 20 and cannot be read by the scanner. When the sheet member 20 is made of a synthetic resin, the sheet member 20 is provided with a sewing line so that the IC chip portion 21 and the antenna portion 22 are easily broken.

  The IC tag 2 has security printing and a model number (laser marking) on its surface, and must be attached so that the printing can be seen from the surface side of the substrate case 1. Therefore, in the present embodiment, before assembling the lid member 1a and the bottom member 1b of the substrate case 1, the back surface of the IC tag 2 is previously placed on the outer surface of the upright wall 12 of the bottom member 1b in the arrow x direction shown in FIG. Adhere to 120 using an adhesive (or adhesive). Then, the lid member 1a and the bottom member 1b are assembled, and the left wall portion 17 and the standing wall 12 of the lid member 1a are brought into contact with each other (the left wall portion 17 of the lid member 1a is relatively in the arrow y direction). The surface of the IC tag 1a is attached to the inner surface 170 side of the left side wall portion 17.

By the way, as shown in FIGS. 6 and 7, since the IC chip 2 has some irregularities on the surface of the IC tag 2, so that these irregularities can be absorbed and pasted, and the lid member 1a and the bottom member In order to be able to absorb and affix them in advance even if there is a variation in the contact between the inner surface 170 of the left side wall portion 17 and the outer surface 120 of the upright wall 12 due to variations in assembly accuracy when assembled with 1b. A sheet-shaped (plate-shaped) transparent synthetic resin cushion member 3 having a thickness (about 1 to 2 mm) is attached to the inner surface 170 of the left side wall portion 17 at a position corresponding to the surface of the IC tag 2. Then, the surface of the IC tag 2 is adhered to the cushion member 3 with an adhesive (or adhesive material). The cushion member 3 is bonded to the inner surface of the left wall portion 17 with an adhesive (or adhesive material) having a stronger adhesive strength than the IC tag 2.
In the illustrated example, the cushion member 3 is provided on the left side wall 17 side, but the present invention is not limited to this and may be provided on the outer surface 120 of the standing wall 12. When the cushion member 3 is attached to the outer surface 120 of the upright wall 12, it need not be made of a transparent synthetic resin. Similarly, although the cushion member 3 has been described as a separate member from the IC tag 2, an IC tag that is stuck and attached on both sides is used, and a cushion portion that has the same role as the cushion member 3 on the surface of the IC tag 2 is provided. It may be provided and is not limited to another member. Moreover, although it demonstrated as providing the cushion member 3 in the position corresponding to the surface of the IC tag 2, even if it provided in the position corresponding to the back surface of the IC tag 2, it corresponds to the position and back surface corresponding to the surface of the IC tag 2. They may be provided individually at the positions where they do not matter, and there is no problem if there is no gap when sandwiched between the inner surface 170 of the left side wall portion 17 and the outer surface 120 of the upright wall 12.

  Further, as shown in FIG. 7, the lid member 1a and the bottom member 1b are assembled, the left side wall portion 17 of the lid member 1a is brought into contact with the upright wall 12 of the bottom member 1b, and the IC tag 2 is adhered. In the state, the overhanging portion 13 provided at the base end of the standing wall 12 and projecting laterally from the base end covers the gap between the tip of the left side wall portion 17 sandwiching the IC tag 2 and the standing wall 12.

According to the present embodiment, since the IC tag 2 is sandwiched between the left wall portion 17 and the standing wall 12 that collide when the lid member 1a and the bottom member 1b of the substrate case 1 are assembled, Even if the IC tag is to be peeled off, the IC tag 2 cannot be directly peeled off manually unless the substrate case 1 is opened.
Further, since both the front and back surfaces of the IC tag 2 are stuck to the two abutting surfaces 170 and 120 of the left side wall portion 17 and the standing wall 12, the substrate case 1 is illegally opened and the lid member 1a and the bottom member 1b are opened. Even if the caulking joint portion is broken, in order to open, both the members 1a and 1b are moved in the left-right direction (lateral The side wall portion 10 of the lid member 1a and the standing wall 12 of the bottom member 1b are separated from each other, and an abnormal tensile force acts on the IC tag 2 due to the separation. Then, the IC tag 2 is broken and destroyed.
Furthermore, since the gap between the tip of the left side wall portion 17 to which the IC tag 2 is attached and the standing wall 12 is covered by the overhanging portion 13 provided at the base end of the standing wall 12, an adhesive or adhesive It is possible to prevent the IC tag 2 from being peeled off using the material solution.
Combined with the effects described above, the discovery of fraudulent acts on gaming machines and the prevention of fraudulent acts are better than before.

  As another embodiment of the present invention, the adhesive strength when the IC tag 2 is adhered to the side wall portion 17 of the lid member 1a and the standing wall 12 of the bottom member 1b may be changed for each portion of the IC tag 2. desirable. For example, as shown in the lower part of FIG. 5, the sheet member 20 of the IC tag 2 is partitioned in a longitudinal direction into a part 220 corresponding to the antenna part 22 and a member 210 corresponding to the IC chip part 21. Then, using two types of adhesives (or adhesives) having different adhesive strengths, the parts 220 corresponding to the left and right antenna portions 22 on the back side of the IC tag 2 are respectively adhesives (or adhesives) having strong adhesive strengths. While the portion 220 corresponding to the IC chip portion 21 is adhered to the standing wall 12 with an adhesive (or adhesive) having low strength, the portion 210 corresponding to the IC chip portion 21 is conversely formed on the surface side of the IC tag 2. A part 220 corresponding to the antenna part 22 is adhered to the side wall part 17 with a weak adhesive (or adhesive) with an adhesive (or adhesive) having high adhesive strength.

  According to this, when the side wall portion 17 and the upright wall 12 are separated from each other by fraud, the portion 210 corresponding to the IC chip portion 21 having a strong adhesive strength to the side wall portion 17 remains on the side wall side 17, and the upright wall 12. Since the portion 220 corresponding to the antenna portion 22 having a strong adhesive strength remains on the standing wall 12, the IC chip portion 21 and the antenna portion 22 can be reliably broken.

The relationship between the adhesive strength between the IC chip portion 21 side and the antenna portion 22 side may be in the reverse state of the above configuration.
Furthermore, in the configuration described in paragraph 0036, since the IC chip portion 21 has a convex shape on the surface of the IC tag 2, the side surface portion 17 (cushion member 3) on the IC chip portion 21 side compared to the antenna portion 22 side. Therefore, the adhesive strength on the IC part chip 21 side is increased, and the surface of the IC tag 2 has a difference in adhesive strength between the IC chip part 21 side and the antenna part 22 side. Therefore, the effect of reliably breaking the IC chip portion 21 and the antenna portion 22 can be obtained without changing the adhesive (or adhesive) between the IC chip portion 21 side and the antenna portion 22 side.

In addition, this invention is not limited to the said embodiment, Of course, it can implement variously in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the IC tag 2 is attached to the left wall portion 17 of the lid member 1a and the standing wall 12 provided at the left end 11 of the bottom member 1b. However, the right wall portion of the lid member 1a A configuration in which the IC tag 2 is attached to a standing wall provided at the right end of the bottom member 1b may be used.
Further, in the above embodiment, the gap between the side wall portion 17 sandwiching the IC tag 2 by the overhang portion 13 and the standing wall 12 is covered, but as described above, in the configuration of the present invention, the IC is manually operated. Since the tag 2 cannot be peeled off, it is impossible to peel off the IC tag 2 without destroying it even if a solution is used. Therefore, the overhanging portion 13 is not necessarily required.
Further, the cushion member 3 used for attaching the surface of the IC tag 2 is not necessarily required if the surface of the IC tag 2 is flat and the front surface can be brought into contact with the side wall portion 17. However, if the cushion member 3 is not provided, accuracy is required when the substrate case 1 is assembled and the side wall portion 17 and the standing wall 12 are brought into contact with each other, and the cushion member 3 protects the IC tag 2. Since the effect can be expected, it is desirable to provide the cushion member 3.
