Description

  The present invention relates to a gaming machine having a control device in which a control board is housed in a board box.

  A gaming machine such as a pachinko machine that plays a game with a winning or non-winning game ball or a slot machine that plays a game with a combination of multiple numbers and symbols is equipped with a control device that houses a control board in a board box. . And most of the games are controlled by this control device, so in recent years, the substrate box of the control device is disassembled into a base body and a lid body, and the control board inside is taken out and an unauthorized person is taken out. There has been a fraudulent act of switching to something advantageous to

  And, for such a fraudulent act, a seal seal provided with an adhesive layer on the back surface of the base sheet is used, and the seal seal is pasted on the boundary portion between the base body and the lid body and sealed. (For example, refer to Patent Document 1).

JP-A-9-225092

  A certain fraud prevention effect can be obtained by sticking and sealing a sealing seal between the base body and the lid body. For example, an unauthorized person can use a solvent suitable for peeling the adhesive layer of the sealing seal. After removing the sealing sticker, and then removing the lid from the base body and replacing the control board, etc., close the lid and reapply the peeled sealing sticker, or break the sealing seal, and In the same way as the above, a new technique of fraud in which the control board and the like are replaced and then pasted so that the joint is not conspicuous has been a problem.

  The present invention has been made in view of the above, and an object of the present invention is to provide a gaming machine that can effectively prevent a fraudulent act of falsifying a seal seal that has been once peeled or torn.

In order to achieve the above object, the present invention

A game machine having a sealing seal formed by forming an adhesive layer on the back surface of a base sheet, and sticking and sealing the base body and the lid so as to straddle the boundary portion Because
The seal seal has a two-dimensional code readable on the surface via a reader,
On the other hand, the substrate box provides a gaming machine having damage imparting means that makes it difficult or impossible to read the two-dimensional code by the reader by a seal releasing operation for unlocking the seal.

  According to the present invention, since the seal seal provided with the two-dimensional code and the damage applying means for damaging the two-dimensional code by the seal release operation for releasing the seal of the seal seal are combined, the seal of the seal seal is released. Opening the substrate box makes it difficult or impossible for the reader to read the two-dimensional code. Therefore, even if such a seal is reapplied to avoid visual detection, it can be surely discovered by daily inspection for management in which the information of the two-dimensional code is read by a reader.

[Embodiment 1]
Embodiment 1 of the present invention will be described below with a pachinko machine that is a kind of gaming machine.
For convenience, the gaming machine will be described with the player side as the front and the opposite side as the rear. In addition, a control device, which will be described later, mounted on the gaming machine has a player side (side closer to the player) as the front and the opposite side as the rear with reference to the installation state, and “front”, “rear”, “Top” and “Bottom” are shown as reference.

[All gaming machines]
As shown in FIG. 20, the gaming machine is attached to a square frame-shaped outer frame 1, a front frame 2 attached to the front surface of the outer frame 1 in a door-opening shape, and a rear surface of the front frame 2. And a mechanism panel 3. The mechanism board 3 is attached so as to cover the rear surface of a game board (not shown) attached to the front frame 2 so as to be detachable and replaceable, and a ball tank 4 for storing game balls, and the ball tank 4 and a prize ball discharge device 6 for releasing the game ball of the game ball 5 as a prize to the player, and controls the game on the lower side. A control device 7 is provided.

[Control device]
The control device 7 is configured by storing a control board 9 (for example, see FIGS. 5A and 5B) in which electronic parts such as a CPU and a memory are mounted in a board box 8 having a box structure with a lid that can be opened and closed. Yes, it is detachable from the mechanism panel 3.

[Board box]
The substrate box 8 is generally composed of a base body 10 corresponding to the “body” of the box with lid and a lid body 11 corresponding to the “lid” of the box with lid.
The base body 10 is made of, for example, a transparent synthetic resin such as polycarbonate, and includes a horizontally-long rectangular front plate 12 that abuts the mechanism panel 3 and a side wall 13 that protrudes backward from the front plate 12. The rear surface is open.
On the other hand, the lid body 11 is made of a transparent synthetic resin such as polycarbonate, for example, and has a horizontally long rear plate 14, a side wall 15 projecting forward from the rear plate 14, and formed inside the side wall 15. The inner wall 15a has a front opening shape.
In the base body 10 and the lid body 11, the opening size of the side wall 13 of the base body 10 is slightly smaller than the opening size of the side wall 15 of the lid body 11, so that the lid body 11 is disposed outside the side wall 13 of the base body 10. And the inner wall 15 a of the lid body 11 is fitted inside the side wall 13 of the base body 10.

  3 and 4 of the base body 10 and the lid body 11, the left side walls 13 and 15 have a hinge structure that can be joined and separated. Specifically, as shown in the partial cross section of FIG. 4 and an enlarged view thereof, an inverted U-shaped bag portion 16 is provided on the side wall 13 of the base body 10, while an L-shaped bag is provided on the side wall 15 of the lid body 11. By providing the portion 17 and engaging the L-shaped flange portion 17 of the lid body 11 while turning around the bag portion 16 of the base body 10, the lid body 11 is rotatably supported with respect to the base body 10, and It is separable. Note that a knob 18 that facilitates opening and closing of the lid 11 is provided at the center position on the right side wall 15 of the lid 11 in FIG.

[Sealing means]
In addition, the base body 10 and the lid body 11 are joined and sealed to the right side walls 13 and 15 of the base body 10 and the lid body 11 in FIG. The sealing means 19 which destroys is formed.
Specifically, as shown in FIGS. 2 and 3, the sealing projection 20 of the lid 11 and the sealing projection 21 of the base body 10 are aligned, and a circled “1” is marked on the lid 11. The square recesses 22a, 22a are joined to each other through screws (not shown), and the recesses 22a, 22a are sealed with plug members (not shown) so that the screws cannot be removed. Thus, when the seal is released, the weakened portion indicated by the symbol z in FIGS. 2 and 3 of the base body 10 and the lid body 11 is broken with a tool such as a nipper.
The sealing means 19 is formed with second recessed portions 22b and 22b engraved with a circled "2" on the lid 11, and the fragile portion z is broken for necessary inspection. Even when the lid 11 is opened, it can be sealed again using the second recessed portions 22b and 22b.

  Further, the side walls 13 and 15 on the lower side in the longitudinal direction in FIG. 3 of the base body 10 and the lid body 11 are joined together by two screws 23 and 23 as shown in FIGS. Specifically, as shown in FIG. 9, the rear plate 14 of the lid body 11 extends downward to form a screw-like hook-shaped portion 25 having the countersink 24 for inserting the screws 23 and 23. On the other hand, as shown in FIGS. 8 and 9, a screw receiving portion 26 is provided on the outer surface of the side wall 13 of the base body 10 so as to substantially align with the flange-like portion 25, and the screw formed on the screw receiving portion 26. The base body 10 and the lid body 11 are also joined to the receiving boss part 27 by passing the screws 23 and 23 from the countersink 24 of the bowl-like part 25 and tightening the screws 23 and 23.

  In the first embodiment, as shown in the enlarged view of FIG. 8, the boss portion 27 of the screw receiving portion 26 of the base body 10 bulges outward from the outer surface of the screw receiving portion 26 (see FIG. 8). In this case, the rail-shaped bulging portion 27a is continuous in the depth direction. By doing so, the thickness of the screw receiving portion 26 can be suppressed without impairing the thickness (strength) of the boss portion 27 necessary for screwing, and the seal fits into the concave groove 29 of the seal breaking plate 28 described later. An effect of allowing the fracture plate 28 to slide straight and accurately is obtained.

Further, as shown in FIG. 9, the heads 23a of the two screws 23, 23 are covered by a sealing seal 30 that is pasted across the joint boundary between the base body 10 and the lid body 11, It is sealed so that it cannot be removed as it is.
Specifically, as shown in FIG. 9, a concave surface portion 31 extending from the flange-shaped portion 25 of the lid 11 to a part of the rear plate 14 is formed, while the screw plate is received on the front plate 12 of the base body 10. A seal adhering plate 32 protrudes from the portion 26 at a distance corresponding to the thickness of the seal fracture plate 28 described later, and the seal adhering plate 32 and the concave surface portion 31 of the lid 11 are formed on the concave surface portion 31 of FIG. In the middle of the surface, as shown in FIG. 5A, a seal seal 30 with a caution display 33a such as “opening prohibited” is attached. The seal sticking plate 32 and the concave surface portion 31 are in a substantially perpendicular positional relationship. Therefore, the seal seal 30 is stuck to the substantially perpendicular corner of the substrate box 8 in a folded state, and in the folded state, “opened” The “prohibited” caution display 33a is clearly visible from the rear side of the substrate box 8 as shown in FIG.

[Sealed seal]
As shown in FIGS. 15 (a) and 15 (b), the seal seal 30 includes both a break (when separated by a sharp blade and a case where it is separated by a so-called blunt blade that is not cut well). The same applies hereinafter. The base sheet 34 is formed of a material such as possible paper or resin sheet, has a horizontally long rectangle as a basic shape, and has a jagged outer periphery, and is formed on the back surface of the base sheet 34. For example, it comprises an adhesive layer 35 based on a polyester resin, an acrylic resin, a rubber resin, or the like.

  A two-dimensional code 33b that can be read via a reader is formed on the surface of the seal seal 30. The two-dimensional code 33b according to the first embodiment is a so-called QR code (registered trademark, the same applies hereinafter) in which information related to the gaming machine or the control device 7 is recorded by a combination of two-dimensional cells. It can be read by a reader such as a functional portable terminal (so-called “smartphone”). Note that the information of the two-dimensional code 33b read by the reader is transmitted to the management computer of the game hall and appropriately processed. Of course, the information recorded in the two-dimensional code 33b and the usage method thereof are arbitrary.

Further, a hologram 33c for preventing duplication is formed in a vertical band shape on the surface of the seal 30 so as to partition the warning indication 33a of the “unopening” and the two-dimensional code 33b, and a warning indication 33a The control number 33d of the seal seal 30 is formed above the top and the adhesive layer 35 can be acted on the adhesive layer 35 along both the upper and lower sides to kill (mainly dissolve) the adhesiveness or tackiness. For example, an ethanol-based solvent A linear visual check portion 33e is formed by the ink that melts in response to the above, and furthermore, a striped pattern for preventing duplication is applied to the peripheral portion of the jagged edge although not shown.
Further, the seal 30 is provided with a cut 36 for increasing the difficulty of physical peeling work.

  Thus, the substrate box 8 according to the first embodiment is provided with damage applying means that makes it difficult or impossible to read the two-dimensional code 33b by the reader by releasing the seal of the seal seal 30.

[Damage imparting means]
The damage imparting means according to the first embodiment is generally composed of a transparent cover member 38 that protects the seal seal 30 and a seal fracture plate 28 that breaks the seal seal 30 to release the seal.

[Cover member]
As shown in FIGS. 9 and 10, the cover member 38 includes a lid-side cover piece 39 that fits into the concave portion 31 of the lid 11 and is flush with the rear plate 14 of the lid 11, and the base body 10. A base side cover piece 40 along the outer surface of the seal sticking plate 32, and side cover pieces 41, 41 projecting on both sides of the base side cover piece 40 and surrounding both sides of the seal sticking plate 32, L-shaped receiving pieces 42, 42 protruding from the lateral cover pieces 41, 41.

  As shown in FIGS. 7 and 13, the cover member 38 is attached to the substrate box 8 in a state where the attaching / detaching direction is regulated in the front-rear direction by the guide means.

  As shown in FIGS. 7 and 13, the specific guide means includes lid-side guide pieces 43, 43 projecting on both sides of the hook-like portion 25 of the lid body 11, and the front plate 12 of the base body 10. Base-side guide pieces 44, 44 projecting from and facing the lid-side guide pieces 43, 43, and projecting outward from the front plate 12 and the side wall 13 of the base body 10 and projecting outward from the base-side guide pieces 44, 44. 13 and a cover receiver 45 that surrounds the cover side. As shown in FIG. 13, the lid side guide pieces 43 and 43 and the base side guide piece 44 are formed on the inner surfaces of the horizontal cover pieces 41 and 41 of the cover member 38. 44, the outer surface of the cover member 38 abuts to restrict the lateral movement of the cover member 38, and the base side cover piece 40 of the cover member 38 is connected to each of the lid side guide pieces 43, 43 and the base side guide pieces 44, 44. Sandwiched between the end face and the cover receiver 45 of the base body 10 Vertical direction of the cover member 38 to restrict the movement of the (Fig. 7, a direction perpendicular to the paper surface in FIG. 13), with the mounting and dismounting direction of the cover member 38 for restricting the longitudinal direction.

  Further, the guide means has a key piece 46 that can be elastically deformed in the base side guide piece 44 as shown by a solid line and an imaginary line in the enlarged view of FIG. The cover member 38 is fixed by engaging with a locking hole 47 formed in the lateral cover piece 41.

  In this fixed state, as shown in FIG. 9, the cover member 38 does not have a place to be caught by a finger because the cover-side cover piece 39 is fitted to the concave surface portion 31 of the cover body 11, and the cover member 38 Since the front end of the member 38 is also surrounded by the cover receiver 45, there is no place where the finger is caught and pulled, and the key piece 46 engaged with the locking hole 47 has no means for releasing the engagement from the outside. . Therefore, it is difficult to remove the cover member 38. This itself is convenient from the viewpoint of protecting the sealing seal 30 by the cover member 38. However, on the other hand, the cover member 38 needs to be removable when performing a regular inspection. Therefore, in the first embodiment, a small gap t is provided between the L-shaped receiving pieces 42 and 42 projecting on both sides of the cover member 38 and base plates 48 and 48 are projected from the base body 10. A tool such as a flat-blade screwdriver is inserted between the base plates 48 and 48 and the L-shaped receiving pieces 42 and 42 so that a large force is applied by the lever action. The engagement can be forcibly released. In other words, the cover member 38 of the first embodiment can be removed by sliding in the direction regulated by the guide means only when a large force is applied by a tool.

  10 and 11, reference numeral 49 is a protrusion protruding from the concave portion 31 of the lid body 11, and the sticking area of the seal seal 30 is clarified by the protrusion 49 and the seal seal 30. An appropriate gap is provided between the surface and the cover-side cover piece 39 of the cover member 38 to prevent the surface of the seal seal 30 from being rubbed and damaged by the cover member 38. On the other hand, if the end of the cover member 38 on the side close to this is pressed against the concave portion 31 by providing the protrusion 49, the end on the opposite side of the cover member 38 is lifted with the protrusion 49 as a fulcrum. As shown in FIG. 12, a pillow piece 50 having substantially the same height as that of the ridge 49 is provided on the side edge of the cover side cover piece 39 of the cover member 38. Incidentally, the lift of the end of the cover side cover piece 39 of the cover member 38 inserts a tool between the cover side cover piece 39 and the cover body 11 to destroy the cover side cover piece 39, and the sealing seal 30 thus exposed. Is unfavorable because it may lead to fraudulent removal of the screw 23, 23 under the solvent and the like, and removing the screws 23, 23 below.

[Seal fracture plate]
As shown in FIGS. 10 to 13, the seal breaking plate 28 includes the screw receiving portion 26, the seal attaching plate 32, the base side guide pieces 44 and 44, the lid side guide pieces 43 and 43, the cover receiver 45, and the like. A transparent synthetic resin plate colored in red or the like in a shape that fits perfectly in the storage unit 51 that is partitioned into five surfaces orthogonal to each other as shown in FIGS. Can be prevented.) The seal breaking plate 28 includes a main plate portion 53 that is disposed substantially in parallel with the longitudinal side of the seal seal 30 and has a length longer than the longitudinal side, and an end portion on the side of the seal seal 30 between the main plate portion 53. A one-way clutch pawl constituting the connecting means for connecting to the cover member 38, and a sub-plate portion 54 which is positioned at a right angle and intersects the main plate 53 at a right angle and is arranged substantially parallel to the short side of the seal 30 55, 55.

The main plate portion 53 is directly under the bent portion of the seal seal 30 in the state of being stored in the storage portion 51, and as shown in FIG. 3, the caution display 33a, the hologram 33c, and the two-dimensional code 33b (QR). In the case of a code, it includes a margin part on the outer periphery of the data area.) The edge that crosses the lower side and faces the back surface of the seal seal 30 is formed in a substantially W shape. Further, the end edge of the main plate portion 53 is a blunt blade-like portion 56 having a sharp tip with a flattened edge and a reduced sharpness. Therefore, there is no fear of cutting the hand by the blade-like portion 56, and the cut end is appropriately roughened, so that restoration becomes difficult.

[Seal rupture plate ... sub-plate part]
The sub-plate portion 54 is formed at the top of the mountain of the main plate portion 53 and in a state of being substantially parallel to the short side of the seal seal 30 in the state of being stored in the storage portion 51, as shown in FIG. As shown, it is located below the caution display 33a and the management number 33d. Further, the edge of the sub-plate portion 54 is a slender blade-like portion 57 that has a sharp and sharp tip and is sharpened like the edge of the main plate portion 53, but the entire edge is slanted straight. In this way, a force that pushes up the sealing seal 30 is concentrated on one point of the blade-like portion 57 by forming it like a stamped sword (also referred to as a “cutting sword”).

[Seal break plate ... one-way clutch pawl]
The one-way clutch claws 55, 55 are formed on both sides of the main plate portion 53 of the seal breaking plate 28 as shown in FIG. 10, and face the base side cover piece 40 of the cover member 38 as shown in FIG. 16A. It is an elastically deformable member that hangs down in an inclined manner. On the other hand, on the inner surface of the base side cover piece 40 of the cover member 38, hook pieces 58 and 58 that can be engaged with the one-way clutch claws 55 and 55 only when the cover member 38 is slid in the removing direction are projected. The hook pieces 58 and 58 and the one-way clutch claws 55 and 55 constitute a connecting means, and the seal breaking plate 28 and the cover member 38 are connected by the connecting means.

[Others]
1, 2, etc., reference numerals 64, 64... Are located on the entire side wall 13 on the upper side in the longitudinal direction in FIG. 3 of the base body 10 and on the outside of the side wall 13 excluding the cover receiver 45 and the leg wall 62 on the lower side in the longitudinal direction. It is a short-shaped protective wall that protrudes, and covers the outside of the side wall 15 of the lid 11 so that a foreign object that tries to pry between the base body 10 and the lid 11 cannot be inserted.

[Assembly of the board box]
In the substrate box 8 having the above configuration, first, the control board 9 is mounted on the base body 10, the lid body 11 is placed thereon, the screws of the sealing means 19 are tightened, and the base body 10 and the lid body 11 are joined. Further, the rectangular recess portions 22a and 22a of the sealing means 19 are filled with a stopper member and sealed. In addition, the two screws 23 and 23 are tightened into the screw receiving portion 26 to join the base body 10 and the lid body 11 again.

[Storing the broken seal plate]
Next, as shown by arrow I in FIG. 13, the seal fracture plate 28 is stored in the storage portion 51 of the base body 10. In addition, a recessed portion 65 is formed in the flange-shaped portion 25 and the screw receiving portion 26 of the lid body 11 and the seal attaching plate 32 of the base body 10, and the auxiliary portion of the seal breaking plate 28 is formed in the recessed portion 65. The plate portion 54 is accommodated. The sub-plate portion 54 of the seal fracture plate 28 can be accurately positioned by the recessed portion 65.

[Attaching seal seal]
Next, as shown by arrow II in FIG. 13, the sealing seal 30 is affixed to the concave surface portion 31 of the lid 11 and the seal sticking plate 32 in a bent state. In this state, the heads 23 a of the screws 23, 23 are covered with the seal seal 30, and the opening above the storage portion 51 is covered with the seal seal 30. Accordingly, the blade-like portion 56 of the main plate portion 53 of the seal breaking plate 28 faces the back side of the caution display 33a, the hologram 33c and the two-dimensional code 33b of the seal seal 30, and the sub-plate portion 54 of the seal breaking plate 28 is sealed. Opposite the caution display 33a of the seal 30 and the back side of the management number 33d.

[Attaching the cover member]
Next, the cover member 38 is slid along the guide means as shown by arrow III in FIG. At this time, it is pushed by the horizontal cover piece 41 of the cover member 38 and the base side guide piece 44 of the base body 10 (strictly speaking, a rod-like portion integrated with the key piece 46 as shown by an imaginary line in the enlarged view of FIG. ) Are elastically deformed and escape inward, and when the pressing of the cover member 38 is completed, the key piece 46 moves back and engages with the locking hole 47 of the lateral cover piece 41 by its own elasticity.
On the other hand, when the cover member 38 is slid along the guide means, the hook pieces 58, 58 get over this while elastically deforming while pushing the opposite side of the one-way clutch claws 55, 55 of the seal breaking plate 28. Then, immediately after the hook pieces 58, 58 of the cover member 38 have passed through the one-way clutch pawls 55, 55, the one-way clutch pawls 55, 55 are moved back by their own elasticity, and the hook pieces of the cover member 38 as shown in FIG. 6A. 58 and 58 face each other.

  In this state, the control device 7 is mounted on the mechanism panel 3 of the gaming machine, and the seal seal 30 is visually confirmed by daily inspection to check for the presence or absence of fraud. Further, predetermined management is performed by reading information from the two-dimensional code 33b of the seal seal 30 by a reader.

[Removing the cover member]
Next, a case where the cover member 38 is removed by regular inspection or the like will be described.
As described above, the cover member 38 is firmly joined, and the gap into which the tool is inserted is a gap t between the L-shaped receiving pieces 42 and 42 on both sides of the cover member 38 and the base plates 48 and 48 of the base body 10. Therefore, a large force is applied in the direction of widening the interval t by lever action by inserting a tip of a tool such as a flat-blade screwdriver into the gap t. With this force, the engagement between the key piece 46 and the locking hole 47 is forcibly released, and the cover member 38 slides in the removing direction. By sliding the cover member 38, the hook pieces 58, 58 of the cover member 38 and the one-way clutch claws 55, 55 are engaged with each other as shown in FIG. 16A. In the first embodiment, as shown in FIG. 1, a barrier 52 that restricts the width of the gap t to a size that can be inserted by a flat-blade screwdriver is provided, and the barrier 52 prevents an easy operation using a coin or the like. It is.

  Next, when the cover member 38 is further slid, the hook pieces 58 and 58 and the one-way clutch claws 55 and 55 are completely engaged as shown in FIG. 17A, and the seal breaking plate 28 slides together as shown in FIG. 17B. . By the sliding of the seal breaking plate 28, the blade-like portion 57 of the sub-plate portion 54 breaks through the seal seal 30 and reliably breaks the caution display 33a and the management number 33d.

  Next, when the cover member 38 is further slid, the blade-like portion 56 of the main plate portion 53 comes into contact with the seal 30 after the sub plate portion 54. Since the seal seal 30 has already been split in a different direction by the sub-plate portion 54, the main plate portion 53 breaks relatively easily by entering the split, as shown in FIGS. 18A, 18B, and 19. The seal breaking plate 28 comes out of the storage portion 51 in a state of being integrated with the cover member 38. As a result, the caution display 33a, the hologram 33c, and the two-dimensional code 33b are collectively broken.

  Thereafter, the weakened portion indicated by the symbol z in FIGS. 2 and 3 of the sealing means 19 is broken with a tool such as a nipper, and the lid 11 is removed from the base body 10 and the control board 9 is inspected. . Then, after the inspection is completed, the base body 10 is covered with the cover body 11 and sealed again using the second recessed portions 22b and 22b as described above, and the cover member 38 is attached by replacing with a new seal seal 30. To do.

[Illegal conduct ... Removal of cover member]
For the control device 7 of the first embodiment, the cover member 38 is removed, the lid body 11 is removed from the base body 10, the regular control board 9 is replaced with an unauthorized one, and the cover member 38 previously removed is removed. There is a fraudulent act that attempts to reverse and prevent the detection of fraud.

  In this case, when the cover member 38 is removed, the sealing plate 30 is completely broken by the main plate portion 53 of the seal breaking plate 28 at a position passing through the two-dimensional code 33b, the caution display 33a, and the hologram 33c. At 54, the warning display 33a and the management number 33d are broken. Therefore, a torn mark can be left on all visible elements.

The sealed seal 30 in which the hologram 33c, the caution display 33a, the management number 33d, and the two-dimensional code 33b are broken can of course be found by visual inspection. However, if the employee is intentional (the employee has taken part in an unauthorized person) Even if the seal seal 30 is overlooked due to error, it can be reliably detected by causing a reading error when managing the two-dimensional code 33b by the reader.
In the first embodiment, since the broken portion of the seal seal 30 is along the bent portion and the cut end is likely to jump up, the visual discovery is easy and the damage to the two-dimensional code 33b is more reliable.

  By the way, the QR code is provided with an “error correction function” in the system so that the reading accuracy can be set in stages. Preferably, the setting value of the error correction function of the QR code is preferably set. It is better to dare to the lowest level. This is because the seal 30 of the first embodiment is covered with the cover member 38, so that the cause of dirt and scratches is presumably due to fraudulent acts. This is because it is advantageous in detecting fraud.

The technical idea grasped from the first embodiment is as follows.
[Technical idea of Embodiment 1]
The damage imparting means according to claim 1 is:
A cover member that covers the seal seal in a mounted state and whose removal direction is regulated by a guide means in a predetermined sliding direction;
A storage section provided at a position opposite to the back side of the seal seal;
A seal breaking plate stored so as to be slidable in the same direction as the removing direction of the cover member in the storage portion,
Furthermore, the seal breaking plate is
In the state where it is stored in the storage portion, it is connected to the cover member by connecting means, and is thus slid in the detaching direction in conjunction with the cover member. The dimension code is broken and pulled out from the storage unit.

[Embodiment 2]
In the second embodiment, a second damage imparting means is added to the substrate box 8 of the first embodiment.
This second damage imparting means forms a solvent-reactive ink portion 37 that changes color in response to a solvent that can peel off the adhesive layer 35 on the background portion of at least the two-dimensional code 33b of the base sheet 34. In addition, the color after the solvent reaction of the solvent-reactive ink section 37 and the color of the two-dimensional code 33b are combined to make it difficult or impossible to read the two-dimensional code by the reader.

  The sealing seal 30 according to the second embodiment is a solvent (for example, ethanol, methyl ethyl ketone, methyl isobutyl ketone, etc.) that can peel the adhesive layer 35 over the entire surface, and acts on the adhesive layer 35. A solvent-reactive ink portion 37 that changes color in response to a solvent that can kill the adhesiveness or tackiness is uniformly formed. The solvent-reactive ink section 37 is formed by applying solvent-reactive ink to the surface of the base sheet 34 or soaking it into the base sheet 34.

  The ink that forms the solvent-reactive ink portion 37 is, for example, a leuco dye and a developer dispersed in a binder resin, and is usually transparent, but develops color when exposed to the solvent such as ethanol. The agent dissolves and reacts with the leuco dye to change color.

  The color after the solvent reaction of the solvent reaction type ink unit 37 can be appropriately set to red, blue, green, black, or the like depending on the combination of the leuco dye and the developer. In the second embodiment, the two-dimensional code is used. Both the color 33b and the color after the solvent reaction of the solvent-reactive ink section 37 are set to “black”.

[Illegal acts ... peeling of seals with solvents]
With respect to the control device 7 of the second embodiment, the cover member 38 that protects the seal seal 30 is destroyed and removed, the exposed seal seal 30 is soaked with a solvent and peeled off, and the cover body 11 is removed from the base body 10. After replacing the regular control board 9 with an unauthorized one, and then re-attaching the seal seal 30 previously peeled off, the cover member 38 previously destroyed is replaced with the cover member of the board box 8 obtained separately. There is a fraudulent act that tries to prevent fraud.

On the other hand, in the seal seal 30 of the second embodiment, the solvent-reactive ink portion 37 changes to black in response to the solvent for peeling, so that traces of solvent use remain throughout the seal seal 30. Further, since the background portion of the two-dimensional code 33b changes to black, the contrast between light and dark becomes unclear, so that reading by a reader becomes difficult or impossible.
Therefore, even if the seal seal 30 peeled off with the solvent is reapplied and covered with another cover member 38, the seal sticker 30 is discolored due to discoloration. Moreover, even if an employee deliberately (in the case where the employee is complicit in an unauthorized person) or negligently overlooks the discoloration of the seal seal 30, a reading error occurs when managing the two-dimensional code 33b by the reader. By doing so, it can be surely discovered.

  By the way, there is a possibility that a fraudster tries to minimize the amount of use of the solvent by combining the peeling with the solvent and the physical peeling, thereby reducing the discoloration of the seal seal 30. A cut 36 for increasing the difficulty of physical peeling work is provided in the proximity of the two-dimensional code 33b so that such a possibility does not occur. This is because the portion provided with the cut 36 has a high probability of using a solvent because physical peeling is difficult (breaks). Therefore, by providing the cut 36 at a position close to the two-dimensional code 33b, the two-dimensional This is because the probability that a solvent is applied to the cord 33b is remarkably increased.

The technical idea grasped from the above embodiment 2 is as follows.
[Technical idea of Embodiment 2]
The damage imparting means according to claim 1 forms a solvent-reactive ink portion that changes color in response to a solvent capable of peeling the adhesive layer on at least a background portion of the two-dimensional code of the base sheet. In addition, the color after the solvent reaction of the solvent-reactive ink portion and the color of the two-dimensional code are combined to make it difficult or impossible to read the two-dimensional code by the reader.

[Embodiment 3]
In the third embodiment, the third damage imparting means is added to the substrate box 8 of the first or second embodiment.
This third damage imparting means is formed of ink that dissolves in response to, for example, an ethanol-based solvent that can act on the adhesive layer 35 to kill the adhesiveness or tackiness of the two-dimensional code 33b. It is a thing.
According to the third damage imparting means, when an illegal act of peeling the seal seal 30 with a solvent is performed as in the second embodiment, the shape of the two-dimensional code 33b itself is lost due to dissolution in the solvent. Reading is difficult or impossible. Therefore, the same fraud prevention effect as that of the second embodiment can be obtained.

The technical idea grasped from the third embodiment is as follows.
[Technical idea of Embodiment 3]
The damage imparting means according to claim 1 is characterized in that the two-dimensional code is formed of ink that melts in response to a solvent that can peel off the adhesive layer.

[Other fraud prevention measures]
Embodiments 1 to 3 described above are intended to prevent fraud by damaging the two-dimensional code 33b. However, the damage imparting means of the second embodiment is modified and used as a fraud prevention means that can identify an unauthorized person. You can also.
That is, the two-dimensional code 33b is formed of a normal ink that does not react with the solvent and a solvent-reactive ink that changes color in response to a solvent that can peel off the adhesive layer 35. The dimension code 33b changes so that illegal information is transmitted by reading by the reader.
Specifically, when the two-dimensional code 33b is a QR code, a basic information is recorded with normal ink, and a cell for notifying illegal information is prepared with ink that changes color in response to a solvent (normally transparent). When the seal seal 30 is peeled off with a solvent, the cell is discolored and fraud detection information that can be read by a reader appears.
Needless to say, since the change of the two-dimensional code 33b is difficult to understand with the naked eye, it is possible to alert a person who has made a fraud using a solvent by pretending that the degree of perfection is high. On the other hand, if the information of the two-dimensional code 33b is read by daily inspection, fraud is immediately detected. Therefore, if the gaming machine is monitored during business hours, it is possible to identify a fraudulent person who tries to be alert and commit a crime. Attracting necessary measures such as restraint of personality.

The technical idea grasped from the above fraud prevention means is as follows.
It has a board box that houses the control board,

Further, the gaming machine is characterized in that fraud detection information that can be read through a reader appears in the two-dimensional code by the color change of the solvent-reactive ink section.

As mentioned above, although this invention was demonstrated about Embodiment 1-3, this invention is not limited to the said embodiment of course. For example, each of the first to third embodiments may be implemented independently, or may be implemented by appropriately combining them. Needless to say, in Embodiments 1 to 3, a higher crime prevention effect can be obtained by implementing a plurality of Embodiments in combination than by implementing them alone.
Moreover, although the embodiment illustrated a pachinko machine as a gaming machine, it can be similarly applied to a slot machine and other gaming machines.
Further, in the embodiment, the blade-like portions 56 and 57 of the seal breaking plate 28 are blunt blades.

  Further, in the embodiment, the connecting means for connecting the cover member 38 and the seal breaking plate 28 is formed by the one-way clutch claws 55, 55 and the hook pieces 58, 58. For example, as shown in FIG. Any material may be used such as bonding the cover member 38 and the seal breaking plate 28 through the rivet 68 from the through hole 67 formed.

  In the second embodiment, the color of the two-dimensional code 33b and the color of the background portion are set to black. For example, when a scanner that captures the two-dimensional code 33b with red light illumination is used as a reader, the two-dimensional code 33b is used. For example, the two-dimensional code 33b and the background part may be set to a combination that reflects (or absorbs) red light.
