Japanese Patent Application Laid-Open No. 2018-166701 (see paragraphs 0101, 0102, etc.)

In recent years, cheating on gaming machines has become more and more sophisticated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gaming machine with enhanced security against fraudulent acts on the board case or the like.

A gaming machine according to the present invention is a gaming machine comprising a front door and a board case for housing a circuit board, wherein the board case comprises a first display section and a second display section, and the first display section and the second display section are provided. The first display unit includes first character information and first code information indicating information that can specify the first character information as a two-dimensional code, and the second display unit includes the first character information and the first code information. is provided with second character information that is different character information, and second code information that indicates information different from the second character information as a two-dimensional code, and the front door is provided with a third display unit, The third display unit includes: third character information different from the first character information and the second character information; third code information indicating information capable of specifying the third character information as a two-dimensional code; and the size of the third code information is larger than that of the second code information.

According to this configuration , while the content of the first character information displayed on the first display section and the content of the identifiable information obtained from the first code information are substantially the same , While the content of the displayed third character information and the content of the identifiable information obtained from the third code information are substantially the same, the content of the second character information displayed on the second display unit and the third character information are substantially the same. By making the content of the information obtained from the two code information different, when the third code information or the first code information is read, the content of the character information and the read code information can be specified. The content of the second character information and the content of the information obtained from the second code information are substantially the same by making them recognize that the content of the information obtained from the second code information is substantially the same, thereby committing fraud. A person who tries to do so can be forced to create a counterfeit substrate case with the wrong second display portion. As a result , it is possible to effectively prevent fraudulent acts related to the substrate case provided with the second display section. In addition, since the size of the third code information arranged on the front door is larger than that of the second code information arranged on the board case, the third code information becomes more conspicuous than the second code information, and the fraudulent person can be motivated to read the third code information rather than the second code information. Furthermore, by doing so, a fraudulent person who knows that the third code information and the third character information have substantially the same content can This can induce the user to believe that the content is the same as that of the second code information, and reduce the willingness to read the second code information which is small and difficult to read.

In addition, when a store clerk checks, it is troublesome to check whether a character string of 9 or 8 digits matches the list. The content of the identifiable information obtained from the one code information is substantially the same, and the content of the second character information displayed on the second display unit and the content of the information obtained from the second code information are different. A counterfeit board case can be easily found by a simple confirmation method of confirming whether or not there is a counterfeit board case. As a result, it is possible to make it difficult to commit fraudulent acts related to the board case having the first display section and the second display section on the surface.

Furthermore, by arranging the first code information that provides information capable of specifying the first character information closer to the center of the substrate case than the second code information that provides information different from the second character information, It is possible to make the first code information easier to read by a reader than the second code information to a fraudulent person who tries to make a counterfeit product. As a result, the fraudulent person first reads the first code information and recognizes that the content of the first character information and the content of the identifiable information obtained from the read first code information are substantially the same. By doing so, it is possible to induce the belief that the content of the second character information and the content of the information obtained from the second code information are substantially the same.

The case knob 83 is fixed to the substrate case 80. When the tip of the case knob 83 is inserted through the insertion hole 81b, it is engaged with the case holding portion 81a. It's becoming

When the case knob 83 is pulled to remove it from the case holding portion 81a, the substrate case 80 becomes rotatable. In this state, the substrate case 80 can be tilted forward with respect to the rotation shaft. As shown in FIG. 5, when the substrate case 80 is rotated about 90° from the holding state and the substrate case 80 falls forward, the surface opposite to the mounting surface 63a of the main control substrate 63 becomes visible, and an abnormality occurs on this surface. It is possible to check whether or not

As shown in FIG. 6, the cover member 80a of the board case 80 includes a front plate 80a1 facing the mounting surface 63a of the main control board 63, a right inner plate 80a2 extending at approximately 90° to the front plate 80a1, It has a right outer plate 80a3, a left inner plate (not shown), a left outer plate (not shown), and a stepped fitting portion 80a4 with the front plate 80a1 on the left side of the left inner plate and the left outer plate.

In the vicinity of the left side surface of the surface 80a4a, there is a projecting breaking portion that breaks a sealing seal 550 (described later) attached to the surface 80a4a and the surface 80b9a1 (described later) when separating the cover member 80a and the base member 80b. 80a4h is formed. Note that the structure of the breaking portion 80a4h is not particularly limited.

The front plate 80a1 includes a main portion 85a arranged substantially parallel to the mounting surface 63a of the main control board 63, and a first concave portion 85b, a second concave portion 85c, and a second 3 recesses 85d. The first recessed portion 85b is formed at a location including a position directly above the main CPU 61 on the mounting surface 63a in a state in which the main control board 63 is accommodated, and restricts movement in the direction directly above the main CPU 61. As shown in FIG. In this embodiment, a recording paper 350, which will be described later, is attached to the front surface (front surface) 85a1a of the main portion 85a of the front plate 80a1. The second recessed portion 85c is adjacent to the left side of the first recessed portion 85b, and is formed at a position adjacent to the substrate case 80 when viewed from the front (viewpoint in the positive direction of the y-axis in FIG. 6). It is a part that looks into the main CPU 61 when checking for fraudulent use of the CPU 61 . An insertion hole 85e through which the connector 68 mounted on the main control board 63 is inserted is formed at the bottom of the third recess 85d.

As shown in FIG. 6, the base member 80b of the board case 80 faces the surface opposite to the mounting surface 63a of the main control board 63, and the board case 80 is held by the support plate 81, and the base member 80b faces the support plate 81. As shown in FIG. 81, a right side plate 80b2, an intermediate plate 80b3, a left side plate 80b4, a lower side plate 80b5, a base left outer side plate 80b8, and a left side plate 80b4 each extending at approximately 90° to the rear side plate 80b1. It has a fitted portion 80b9 on the left side.

A right rotation shaft portion 90a is formed on the outer surface of the right side plate 80b2 (the surface opposite to the housing space), and the outer surface of the base left outer plate 80b8 outside the left side plate 80b4 (the surface opposite to the housing space). A left rotation shaft portion 90b is formed on the side surface). A right bearing hook 81c (see FIG. 14) provided on the support plate 81 supports the right rotation shaft portion 90a. A left bearing hook 81d (see FIG. 14) provided on the support plate 81 supports the left rotation shaft portion 90b.

A plurality of cover locking pieces 80b6 are formed at the front end of the recessed portion of the lower plate 80b5 toward the rear plate 80b1. It is bent at 90° and formed into a hook shape. When the cover member 80a is attached to the base member 80b, the bent portion is arranged in front of the bottom surface of the third recess 85d of the cover member 80a, and forward movement of the cover member 80a is restricted. be done. As a result, the cover member 80a is prevented from being lifted forward from the base member 80b.

The fitted portion 80b9 is recessed in the positive direction of the y-axis (rear side (back side) of the slot machine 1) with respect to the first fitted portion 80b9a and the first fitted portion 80b9a. It has a second fitting formation portion 80b9b. When the cover member 80a and the base member 80b are combined, the fitting portion 80a4 of the cover member 80a is fitted into the depression of the fitted portion 80b9 of the base member 80b. In this state, unevenness is formed at the boundary between the fitting portion 80a4 and the first fitted portion 80b9a of the fitted portion 80b9. The sealing seal 550 is affixed so that a part thereof is located on the uneven boundary between the fitting portion 80a4 and the first fitting forming portion 80b9a of the fitting portion 80b9, and the sealing seal 550 is peeled off. Otherwise, the cover member 80a and the base member 80b cannot be separated.

Next, a rotation mechanism for the substrate case 80 will be described with reference to FIGS. 7 to 15. FIG. 7 is a partially exploded perspective view of the board case 80 held by the support plate 81, and is a perspective view of the board case 80 viewed obliquely from the upper right. 8A is a view of the rotating member cover 86 viewed from the front, FIG. 8B is a view of the rotating member cover 86 viewed from the rear, and FIG. 9 is a view of the bearing member 87 viewed from the front. 10 is a perspective view of the shaft fixing member 88, and FIG. 11 is a perspective view of the cover member 80a when viewed obliquely from the front right bottom, showing an enlarged view of the right outer plate 80a3. FIG. 12 is an enlarged view of the right outer plate 80a3 viewed from the rear, and FIG. 13 is a perspective view of the base member 80b viewed obliquely from the front right below, showing an enlarged view of the right rotation shaft portion 90a. 14 is a perspective view of the substrate case 80 held by the support plate 81 with the rotating member cover 86 removed, viewed obliquely from the lower right front side, and FIG. It is a B arrow directional cross-sectional view, Comprising: It is an enlarged view of a rotation mechanism.

As shown in FIG. 13, a right rotation shaft portion 90a is formed on the right side plate 80b2 of the base member 80b. The right rotation shaft portion 90a has a cylindrical shaft portion 90a1 and a flange portion 90a2 formed on the outer peripheral surface of the shaft portion 90a1. The shaft portion 90a1 has one end connected to the right side plate 80b2, and is arranged so that the central axis of the cylinder is at 90° to the right side plate 80b2, forming part of the rotation shaft. A through hole is formed in the right side plate 80b2 where the cavity of the shaft portion 90a1 is arranged, and a fixing pin 86a (see FIG. 8) of a rotating member cover 86, which will be described later, can be inserted therethrough.

Two arrangement holes 90a3 are formed in the peripheral surface of the shaft portion 90a1, in which the movement restricting projections 88a (see FIG. 10) of the shaft fixing member 88 are arranged. Further, a locking piece 90a4 is formed on the periphery of each of the arrangement holes 90a3. Each locking piece 90a4 protrudes inwardly of the arrangement hole 90a3 from the edge of the arrangement hole 90a3 on the other end side of the shaft portion 90a1. A cutting line 90a5 is recessed between the other end of the shaft portion 90a1 and the placement hole 90a3 so that the locking piece 90a4 can be removed by cutting the line.

Also, the flange portion 90a2 is formed at a position spaced apart from the right side plate 80b2 by a predetermined distance. A plate-like right bearing hook 81c (see FIG. 14) formed on the support plate 81 is arranged in the gap between the flange portion 90a2 and the right side plate 80b2, so that the lateral movement of the substrate case 80 can be restricted. ing. Furthermore, a locking projection 90a6 is formed on the outer peripheral surface of the shaft portion 90a1. The bearing portion 87b of the bearing member 87 is sandwiched between the 90a2 and the substrate case 80 so as to restrict the horizontal movement of the substrate case 80. As shown in FIG.

As shown in FIG. 9, the bearing member 87 is in contact with the support plate 81 and includes a fixed portion 87a formed with a screw hole for fixing to the support plate 81, and an end portion of the fixed portion 87a bent at approximately 90°. and a bearing portion 87b formed with an insertion hole 87c through which the shaft portion 90a1 of the right rotation shaft portion 90a is inserted. The insertion hole 87c is formed with a diameter larger than the diameter of the outer circumference circle of the shaft portion 90a1 so that the shaft portion 90a1 can be inserted therethrough and can rotate.

As shown in FIG. 10, the shaft fixing member 88 includes a cylindrical portion 88d, a movement restricting projection 88a projecting from the outer peripheral surface of the cylindrical portion 88d, and a collar portion formed at one axial end of the cylindrical portion 88d. and an unused hole indicating piece 88c projecting in the axial direction of the cylindrical portion 88d and toward the other end of the cylindrical portion 88d. The outer circumference of the cylindrical portion 88d is formed with a diameter smaller than the diameter of the inner circumference of the right rotation shaft portion 90a formed in the base member 80b, and one end of the cylindrical portion 88d is connected to the right rotation shaft portion 90a. It can be inserted into the shaft portion 90a1.

The collar portion 88b is formed with a size larger than the diameter of the inner peripheral circle of the right rotation shaft portion 90a, and is formed with a size larger than the diameter of the insertion hole 87c of the bearing member 87. As shown in FIG. Therefore, after one end of the cylindrical portion 88d is inserted inside the shaft portion 90a1, leftward movement of the cylindrical portion 88d is restricted by the collar portion 88b.

One end of the cylindrical portion 88d of the movement restricting projection 88a of the shaft fixing member 88 is inserted into the shaft portion 90a1 of the right rotation shaft portion 90a. It is designed not to come off from the member 87 . Specifically, the movement restricting projection 88a is formed so that the projection height increases from one end of the cylindrical portion 88d on the insertion side toward the other end where the flange portion 88b is formed. , the size including the cylindrical portion 88d is larger than the diameter of the inner peripheral circle of the right rotation shaft portion 90a. Therefore, after the cylindrical portion 88d is inserted into the shaft portion 90a1 to the position where the movement restricting projection 88a fits into the arrangement hole 90a3, the leftward movement of the shaft fixing member 88 is restricted by the movement restricting projection 88a. That is, after the cylindrical portion 88d of the shaft fixing member 88 is inserted to the position where the movement restricting projection 88a fits into the arrangement hole 90a3, the substrate case 80 cannot be removed from the bearing member 87 unless the movement restricting projection 88a is removed. It's becoming

Therefore, in this embodiment, the circuit board case 80 is intentionally removed from the bearing member 87 only once so that it can be restored to a normally rotatable state. For example, a case where the movement restricting projection 88a is arranged and positioned in the arrangement hole 90a3 arranged next to the letter "B" of the shaft portion 90a1 shown in FIG. 13 will be described as an example.

In this case, when cutting lines 90a5 formed above and below the letter "B" are cut with a tool, the locking piece 90a4 arranged next to the letter "B" can be removed, and the substrate case 80 can be removed. It can be removed from the bearing member 87 . When the board case 80 is fixed to the bearing member 87 again, it can be fixed again by arranging the movement restricting protrusion 88a in the arrangement hole 90a3 arranged next to the letter "C" of the shaft portion 90a1.

As shown in FIG. 14, when the circuit board case 80 and the bearing member 87 are fixed to each other, the bearing portion 87b of the bearing member 87 becomes an obstacle, making it difficult to see the movement restricting projection 88a. Therefore, it is not known in which arrangement hole 90a3 the movement restricting protrusion 88a is arranged. However, when the movement restricting projection 88a is arranged in the arrangement hole 90a3 adjacent to the letter "B", the cutting lines 90a5 provided above and below the letter "C" are hidden by the unused hole indicating pieces 88c. Therefore, by cutting the exposed cutting line 90a5, it is possible to reliably remove the locking piece 90a4 of the arrangement hole 90a3 in which the movement restricting protrusion 88a is arranged.

Further, as shown in FIG. 14, when the movement restricting projection 88a of the shaft fixing member 88 is arranged in the arrangement hole 90a3 of the right rotation shaft portion 90a, the shaft is fixed in front of the screw hole of the fixing portion 87a of the bearing member 87. A collar 88b of member 88 is positioned to hide the screw hole. As described above, the shaft fixing member 88 cannot be removed unless the locking piece 90a4 is removed. Therefore, once the board case 80 is fixed, the board case 80 can be removed by removing the bearing member 87 from the support plate 81. It is not possible.

Further, these rotating mechanism sections are covered with a rotating member cover 86 so that access to the rotating mechanism section is not possible unless the rotating member cover 86 is removed. As shown in FIG. 8B, the rotating member cover 86 is formed with a rotating side engaging portion 86b when viewed from the rear side. The sealing structure is such that when the side engaged portion 89 (see FIG. 7) is engaged with the rotating side engaging portion 86b, the rotating member cover 86 cannot be removed unless they are destroyed.

Here, although only one rotation-side locked portion 89 of the support plate 81 is provided, the structure is such that it can slide vertically. Therefore, for example, it is engaged with one of the rotation-side engaging portions 86b of the rotating member cover 86 provided at two locations (lower rotating-side engaging portion 86b), and then the one rotating-side engaging portion 86b is engaged. After destroying the engaging portion 86b, the rotating side engaged portion 89 is slid upward and engaged with the other rotating side engaging portion 86b (upper rotating side engaging portion 86b) to re-engage. can be sealed. Along with this, when the rotating member cover 86 is viewed from the front, a cover-side cutting line 86c is formed (see FIG. 8A), and if the line is cut with a tool or the like, the sealing structure can be released. It has become.

By the way, as a method of attaching the lid member 80a to the base member 80b, after fixing the main control board 63 to the cover member 80a with the screws 30, the cover member 80a and the base member 80b are overlapped, and then the cover member 80a is attached. By sliding downward, the cover member 80a is attached to the base member 80b (see FIG. 6). As described above, after the cover member 80a is attached to the base member 80b, the substrate case 80 is tightly sealed by the caulked portion 80c. can no longer be separated. Furthermore, since the right outer plate 80a3 and the left outer plate of the cover member 80a are both arranged inside the base member 80b, once the cover member 80a is mounted on the base member 80b, Movement of the cover member 80a in the left-right direction is restricted. Further, since the cover member 80a is restricted from moving forward by the cover locking pieces 80b6 formed on the base member 80b, in order to separate the cover member 80a from the base member 80b, the cover member 80a must be moved once. should be slid upwards.

However, in this embodiment, the upward sliding movement of the cover member 80a can be restricted by the shaft fixing member 88 that fixes the rotation shaft of the substrate case 80. As shown in FIG. Further, since the shaft fixing member 88 is fixed by the fixing pin 86a provided on the rotating member cover 86, for example, even if the caulking portion 80c is destroyed, the rotating member cover 86 is further removed and the shaft is further fixed. Unless the member 88 is removed, the cover member 80a and the base member 80b cannot be separated. The structure will be described below.

As shown in FIGS. 11 and 12, on the right outer plate 80a3 of the cover member 80a, there is provided a portion for inserting the shaft fixing member 88 at a position corresponding to the position where the right rotation shaft portion 90a of the base member 80b is formed. A cover-side notch 80a6 is formed. The cover-side notch 80a6 is formed in a U shape with an open rear side. A base-side notch 80b7 having substantially the same shape is also formed in the intermediate plate 80b3 of the base member 80b so as to overlap with the cover-side notch 80a6 (see FIG. 13, etc.).

As for the mounting method of the rotating member cover 86, as shown in FIG. The shaft portion 90a1 of the shaft portion 90a is inserted, and the bearing member 87 is fixed with a screw. Subsequently, the board case 80 is fixed with the shaft fixing member 88 .

15 is a cross-sectional view taken along line BB of FIG. It shows the inserted state. The cylindrical portion 88d of the shaft fixing member 88 is formed longer than the width of the bearing portion 87b so as to protrude from the bearing portion 87b toward the board case 80 side. The distal end portion of the shaft fixing member 88 (the end portion of the cylindrical portion 88d opposite to the collar portion 88b) extends through the cover-side notch portion 80a6 formed in the right outer plate 80a3 of the cover member 80a and the intermediate plate of the base member 80b. It is in a state of being inserted into each of the base-side cutouts 80b7 formed in 80b3. Finally, the fixing pin 86a of the rotating member cover 86 is slid to the left so as to be inserted into the cylindrical portion 88d of the shaft fixing member 88, and the rotating member cover 86 is attached. Thereby, the shaft fixing member 88 is fixed by the fixing pin 86a. As shown in FIG. 8(b), the fixing pin 86a is located inside the rotating member cover 86, and is attached to the cylindrical portion 88d of the shaft fixing member 88 and the shaft of the right rotating shaft portion 90a (base member 80b). It is formed at a position where it can be inserted into the portion 90a1.

In this case, even if the cover member 80a is slid upward to be separated from the base member 80b, the cover-side notch 80a6 hits the cylindrical portion 88d of the shaft fixing member 88 fixed to the support plate 81, causing the cover member 80a to move upward. is regulated, making separation impossible. As described above, when the shaft fixing member 88 is to be removed from the right rotation shaft portion 90a, it is necessary to cut the cutting line 90a5 of the right rotation shaft portion 90a. 86 must be removed. In this way, the shaft fixing member 88 has a function of preventing the substrate case 80 from being illicitly removed from the support plate 81 (so-called housing caulking) and a function of preventing the substrate case 80 from being illicitly opened (so-called main body caulking). ), and the crimping function on both sides is centralized to the rotating shaft of the substrate case 80 . In general, it is desirable to protect the structure (crimping structure) that implements such a crimping function with a case or the like in order to block unauthorized access from the outside. However, if both crimping functions are provided at a separate location, it becomes necessary to protect them with individual cases, which not only occupies space inside the housing but also increases costs. Therefore, if both crimping functions are concentrated on the rotating shaft as in this embodiment, the installation range of the case that protects the crimping structure can be reduced, resulting in good space efficiency.

Therefore, even if the crimped portion 80c of the board case 80 is broken, it is not easy to separate the cover member 80a and the base member 80b in the state of being fixed to the support plate 81. FIG. In this way, the sealing structure between the cover member 80a and the base member 80b of the substrate case 80 is also possible on the rotating mechanism side. The fixing pin 86a of the rotating member cover 86 is inserted through the cylindrical portion 88d of the shaft fixing member 88 and the cover-side notch portion 80a6 to reinforce the cylindrical portion 88d of the shaft fixing member 88 and position the rotating member cover 86. has the function of

In the present embodiment, engaging the support plate 81 and the substrate case 80 is defined as "B caulking", and the portion of the substrate case 80 to which the "B caulking" is applied (the rotating side of the rotating member cover 86) 8, which is one of the locking portions 86b, and the rotating side locked portion 89 of the support plate 81) is referred to as the "B caulked portion". defined as The “B caulking portion” connects the board case 80 to the support plate 81 so that the board case 80 is not illegally removed from the support plate 81 after the slot machine 1 is shipped from the manufacturing factory. is removed from the support plate 81 illegally, the trace is left. When inspecting the substrate case 80 and the support plate 81, it is possible to determine whether or not the substrate case 80 has been illegally removed from the support plate 81 by checking the condition of the "B crimped portion" and its surroundings (presence or absence of damage marks, etc.). You can check whether Note that the location where the "B crimped portion" is provided is not particularly limited.

The rotating side engaged portion 89 of the support plate 81 that constitutes the "B crimped portion" is provided only at one location, but is structured to be slidable in the vertical direction. 8, which is one of the rotation-side engagement portions 86b of the rotating member cover 86, on the negative side in the z-axis direction in FIG. move in the direction 8, which is one of the rotary-side locking portions 86b of the rotary member cover 86, and the rotary-side locked portion 89 of the support plate 81. becomes engageable. This engagement is defined as "C crimping", and the portion of the circuit board case 80 to which the "C crimping" is performed (one of the rotation-side locking portions 86b of the rotation member cover 86, which is the z-axis direction positive in FIG. 8) A portion composed of the rotating side locking portion 86b on the side and the rotating side locked portion 89 of the support plate 81) is defined as a "C-crimped portion".

In this embodiment, in addition to the "B crimped part", the "C crimped part" is provided as a spare for the "B crimped part". That is, even after the slot machine 1 is shipped from the manufacturing factory, the board case 80 may be properly removed from the support plate 81 by an on-site inspection by an inspection agency or the like. At the time of this inspection, the aforementioned "B crimped portion" is normally destroyed by an inspection agency or the like. During this inspection, one of the rotation-side engagement portions 86b of the rotation member cover 86, which constitutes the "B caulking portion", was destroyed. However, the rotation-side engaged portion 89 of the support plate 81 is not destroyed and is used as a part of the "C crimped portion". The substrate case 80 after the inspection by an inspection agency or the like is completed needs to be attached to the support plate 81 again. On the other hand, the rotation-side locking portion 86b on the negative side in the z-axis direction in FIG. 8 cannot be used because it has already been destroyed. Therefore, when mounting the circuit board case 80 to the support plate 81 after completion of the inspection, the z-axis in FIG. The substrate case 80 and the support plate 81 are connected by the rotation-side locking portion 86b on the direction positive side and the rotation-side locked portion 89 of the support plate 81 . In this case, the rotating side engaged portion 89 is also used as the "B caulking portion". Incidentally, the place where the "C-crimped portion" is provided is not particularly limited. Further, a "D crimped part" may be provided as a spare for the "C crimped part".

In addition, an "F crimped portion" is provided as another crimped portion. When the main control board 63 is returned to the manufacturer, engaging the base member 80b and the cover member 80a in the board case 80 that houses the main control board 63 is defined as "F caulking". A portion to which "F crimping" is applied is defined as "F crimping part". The "F caulking part" seals the board case 80 so that the board case 80 will not be illegally opened when the main control board 63 is returned to the manufacturer. is the part that leaves the trace. Note that the location where the "F crimped portion" is provided is not particularly limited. In the present embodiment, it is provided on the left side of the "A caulked portion" at the upper right corner of the substrate case 80. As shown in FIG.

Next, the sealing seal 550 will be described with reference to FIG.

As shown in FIG. 17, the rectangular sealing seal 550 is chamfered with, for example, R2 mm at each corner of the outer circumference of the sealing seal 550. The second character information 550b and the second character information 550b are read by using a reader. Second code information 550a, which can read information different from the character information 550b, is displayed.

The second character information 550b includes, for example, the serial number of the seal 550 such as "87654321". In addition, the second code information 550a is printed with a two-dimensional code such as a QR code (registered trademark), and information that can be read by using a reader for the two-dimensional code is, for example, "L4FEUNW388". Random alphanumeric characters such as . Here, the information that can be read by using a two-dimensional code reader is not limited to random alphanumeric characters, and may be information that is only partially different from the second character information 550b, such as "87654331". can be In the case where only a part of the second character information 550b is different from the second character information 550b in this way, even if the second code information 550a is read by using a reader, It is difficult to notice the difference from the characters, and it can be mistaken for being the same. In this embodiment, the second code information 550a is a two-dimensional code such as a QR code (registered trademark), but it may be a one-dimensional code other than the two-dimensional code.

For example, as shown in FIG. 17, when the size of the seal 550 is h=35 mm and g=60 mm, the size of the display area of the second code information 550a is, for example, , j=6 mm, and i=6 mm (the occupation ratio of the display area of the second code information 550a with respect to the entire seal 550 is about 1.7%). Further, the second character information 550b is such that when the size of the sealing sticker 550 is, for example, h=35 mm and g=60 mm, the size of the display area of the second character information 550b is, for example, y2=2 mm and x2= One that is set to 11 mm (the occupation ratio of the display area of the second character information 550b with respect to the entire seal 550 is about 1%) is included. The second code information 550a is formed in a predetermined area of the sealing sticker 550, such as sa2=47 mm, sb2=7 mm, ta2=18 mm, and tb2=11 mm. .

As described above, the size of the display area of the third code information 750a is set to n=7 mm and m=7 mm, for example. On the other hand, as described above, the size of the display area of the second code information 550a is set to j=6 mm and i=6 mm, for example. Thus, the display area for the third code information 750a is larger in size (area) than the display area for the second code information 550a.

Further, as described above, the occupancy rate of the display area of the third code information 750a with respect to the entire certificate stamp 750 is, for example, about 2.5%. On the other hand, as described above, the occupancy rate of the display area of the second code information 550a with respect to the entire seal 550 is, for example, about 1.7%. In this way, the display area for the third code information 750 a occupies the entire certificate stamp 750 and is higher than the display area for the second code information 550 a for the entire sealing sticker 550 .

Also, as described above, the size of the display area of the third character information 750b is set to y3=4 mm and x3=36 mm, for example. On the other hand, as described above, the size of the display area of the second character information 550b is set to y2=2 mm and x2=11 mm, for example. Thus, the display area for the third character information 750b is larger in size (area) than the display area for the second character information 550b.

Further, as described above, the occupancy rate of the display area of the third character information 750b with respect to the entire certificate stamp 750 is about 7.5%. On the other hand, as described above, the occupancy rate of the display area of the second character information 550b with respect to the entire seal 550 is approximately 1%. In this way, the display area for the third character information 750 b occupies the entire certificate stamp 750 , and the display area for the second character information 550 b occupies the entire seal 550 .

In the sealing sticker 550, when the sealing sticker 550 is viewed from the back surface opposite to the front surface on which the second code information 550a, the second character information 550b, etc. are displayed by printing or the like, the two-dimensional information constituting the second code information 550a is viewed from the back surface. Codes and characters that make up the second character information 550b are not so transparent that a person can see their orientations. Note that the second code information 550a may not be transparent from the back surface of the sealing sticker 550 to the extent that it can be read by a reader.

(Recording paper)
Next, the recording paper 350 will be described with reference to FIG.

The recording paper 350 is formed of a light-transmitting sheet, and as shown in FIG. 17, the corners of the outer periphery of the recording paper 350 are chamfered with a radius of 0.3 mm, for example. Here, the recording paper 350 is preferably made of resin such as polyethylene terephthalate (PET) and is not colored. The corners of the outer periphery of the recording paper 350 may not be chamfered.

As described above, each corner of the outer circumference of the sealing seal 550 is chamfered with a radius of 2 mm, for example. . In this way, the chamfered value of R at each corner of the outer periphery of the recording paper 350 is smaller than the value of R of chamfered at each corner of the outer periphery of the sealing seal 550 . Here, the recording paper 350 is made of a transparent seal, and the sealing seal 550 is made of an opaque seal. In the case of transparent stickers, fingerprints, etc., left during the pasting work can be confused with traces of fraud (traces of fraud such as peeling off the transparent sticker, drilling a hole in the substrate case, and attaching the transparent sticker again). . The smaller the R, the smaller the contact area of the finger, etc., and the lower the adhesive force, as well as the prevention of the adhesion of fingerprints and foreign matter adhering to the finger. Smaller is better. On the other hand, when R is large, the working efficiency of the pasting work is improved. Therefore, it is desirable to give priority to workability for opaque seals such as the sealing seal 550 because there is no adverse effect due to adhesion of fingerprints and the like. Moreover, since the sealing seal 550 is provided with the slits 558a and 558b, it is desirable to give priority to workability.

On the recording paper 350, characters related to the regular opening history of the substrate case 80 are formed. Here, as shown in FIG. 18, the characters related to the regular opening history of the board case 80 are "main board number", "record of caulking use", "A", "B", "C", "F", The characters are "use", "main body fixation", "on-site inspection", "board recovery", "date", and "person in charge". Here, "A", "B", "C", and "F" are surrounded by circles as shown in FIG. ", "F". In this embodiment, these characters are formed on the recording paper 350 by printing or the like, but are not limited to this, and may be formed by direct printing or the like on the surface of the substrate case 80 .

In addition, the color of the characters related to the normal opening history of the board case 80 formed on the recording paper 350 is the background color of the main control board 63 (for example, the mounting surface 63 a of the surface of the main control board 63 facing the recording paper 350 ). background color), high-contrast colors are used. A color with high contrast is a color with a large difference in brightness between the outline of the character and the background color. and white. In addition, the color of the characters related to the regular opening history of the board case 80 formed on the recording paper 350 is a color that has a high contrast with respect to the background color of the main control board 63. Such a high-contrast color is This color has a higher contrast than the background color of the main control board 63 and the second colored portion 353 described later.

As will be described later, the recording paper 350 is viewed from the surface 80M of the board case 80 and facing the main control board 63 accommodated in the board case 80 (when viewed from the front of the board case 80). It is attached to a position overlapping the main control board 63 . As a result, the characters related to the normal opening history of the board case 80 formed on the recording paper 350 are the front surface 80M of the board case 80 and viewed from the side facing the main control board 63 accommodated in the board case 80 ( When viewed from the front of the board case 80 , it exists at a position overlapping the main control board 63 .

A surface 80M of the board case 80, which is a portion that does not overlap the main control board 63 when viewed from the side facing the main control board 63 accommodated in the board case 80 (when viewed from the front of the board case 80), and which is a board case. The color of the identification information formed in the second portion 80LD (see FIG. 19) appears cloudy because the thickness of the resin forming the resin forming the circuit board case 80 is thicker than that of the first portion, which makes the substrate case 80 look cloudy. A low-brightness color, such as black, is used as compared with the color of the characters relating to the regular opening history of the substrate case 80 formed on the second portion and the recording paper 350 .

Here, the second portion 80LD is thicker than the first portion due to the overlap of the base member 80b and the cover member 80a, and is a portion that becomes cloudy. For example, the second portion 80LD is the lower left end portion of the board case 80 when the board case 80 is viewed from the front, as shown in FIG. Such a portion looks cloudy due to the overlapping of the base member 80b and the cover member 80a. That is, since the substrate case 80 made of resin has the property of whitening when plastically deformed, it is not formed completely transparent, and when a plurality of members of the substrate case 80 overlap, it appears cloudy. becomes. Note that the second portion 80LD is not limited to the lower left end portion of the substrate case 80 when viewed from the front of the substrate case 80, and can be anywhere as long as the substrate case 80 appears cloudy.

The identification information formed in the second portion 80LD includes characters used in languages such as the alphabet, as well as numbers and symbols. This includes, but is not limited to, identifying information such as model number.

Further, the color of the identification information formed in the second portion is not limited to black. Any color that provides a high contrast for the

Further, as an example of the first portion, the flat plate shape is continuous, and the inside thereof is a portion that is easy to visually recognize. That is, the electronic parts such as the ratio indicator 69 and the monitor LED 32 are made of thin flat plates so that they can be visually recognized. Further, even if the visibility deteriorates due to attachment of something other than the substrate case 80, such as the recording paper 350, it is necessary to ensure a certain degree of visibility.

The second portion 80LD, which makes the board case 80 look cloudy, can be removed by roughening the injection mold used for forming the cover member 80a or the base member 80b of the board case 80, for example, by providing fine unevenness. , and the cover member 80a or the base member 80b may be formed by using the injection mold having the roughened surface.

In addition, the color of the frame line W1 along the outer periphery of the recording paper 350 and the frame line W2 that divides the characters related to the normal opening history of the substrate case 80 with vertical and horizontal lines also correspond to the color of the substrate formed on the recording paper 350. Similar to the color of the characters related to the regular opening history of the case 80, the background color of the main control board 63 (for example, the background color of the mounting surface 63a facing the recording paper 350 among the surfaces of the main control board 63) has a high contrast. A color such as white is used. Note that the frame line W1 is thicker than the frame line W2.

Also, the color with high contrast is similar to the color of characters printed on the mounting surface 80a of the main control board 80 described above. That is, the color of characters printed on the mounting surface 80a of the main control board 80 is similar to white when the background color of the main control board 80 is green. Here, similar colors include the same color.

The ground color of the main control board 80 (for example, the ground color of the mounting surface 63a facing the recording paper 350 among the surfaces of the main control board 63) is not limited to green or black, and may be yellow, red, purple, or the like. can be Here, when the background color is yellow, the characters related to the normal opening history of the board case 80 formed on the recording paper 350 are blue, and when the background color is red, the characters are green and the background color is purple. If the character is a yellow-green color, for example. That is, the high-contrast colors include the ground color of the main control board 80 (for example, the ground color of the mounting surface 63a facing the recording paper 350 among the surfaces of the main control board 63) and the opposite or complementary color of the color wheel. Including colors that are related to

Further, the recording paper 350 includes a light-transmitting portion having a light-transmitting property and a colored portion 351 having a base color of a white color. Here, since the recording paper 350 is formed of a light-transmitting sheet, the light-transmitting portion includes characters and frame lines W1 and W2 related to the normal opening history of the substrate case 80 formed on the colored portion 351 and the recording paper 350 . It becomes a part other than. The colored portion 351 includes a first colored portion 352 whose lightness is higher than that of the second colored portion 353 and a second colored portion 353 whose lightness is lower than that of the first colored portion 352 among white-based colors. Here, brightness refers to the degree of brightness. For example, when there are 10 levels of brightness, the first colored portion 352 is "10" and the second colored portion 353 is "7". (The larger the numerical value representing the degree of brightness, the brighter the image).

Here, the lightness of the first colored portion 352 and the second colored portion 353 may be made different by printing with inks of different colors, or may be made different by the presence or absence of overcoating and the number of times. The first colored portion 352 and the second colored portion 353 may be formed with a base color other than the white color. In order to make the visibility of the main control board 80 good with respect to the background color of the main control board 80 (for example, the background color of the mounting surface 63a facing the recording paper 350 among the surfaces of the main control board 63), both is most desirable.

The first coloring section 352 has a plurality of areas, for example, a seal area 357 on the upper right of the recording paper 350, a date entry area 356a, and a person in charge name entry area 356b. The first colored portion 352 is colored in a rectangular shape, and is white in this embodiment.

On the left side of the seal area 357 provided on the upper right of the recording paper 350, the letter "A" is formed in white as described above. Here, the seal area 357 on the upper right of the recording paper 350 is an area where a seal can be stamped to indicate that the "A crimped portion" is used. It should be noted that it is not limited to stamping, and may be filled in with a writing instrument or the like.

Above the topmost date entry area 356a is "year, month and day", above the topmost person in charge name entry area 356b is "person in charge", and on the left side of the top date entry area 356a is " "B" and "Main body fixing", "C" and "On-site inspection" on the left side of the central date entry area 356a, and "F" and "Recovery of substrates" on the left side of the bottom date entry area 356a. are formed in white as described above.

Here, the character "B" and "fixed body" formed on the recording paper 350 correspond to the "year" when the date entry area 356a and the person in charge name entry area 356b on the same line normally use the "B crimped portion". "Month and date" can be entered by handwriting or stamping with a writing instrument of the worker, and "B crimped part" is an area where the name of the "person in charge" can be entered with a writing instrument. .

In addition, the characters "C" and "on-site inspection" formed on the recording paper 350 correspond to the date entry area 356a and the person-in-charge name entry area 356b on the same line, and the date entry area 356a and the person-in-charge entry area 356b normally use the "C crimped part". ” indicates that it is an area in which the name of the “person in charge” who uses the “C caulked portion” can be written in with a writing instrument or the like.

In addition, the characters "F" and "for board recovery" formed on the recording paper 350 correspond to the "year and month" when the date entry area 356a and the person in charge name entry area 356b on the same line normally use the "F crimped portion". This indicates that the name of the "person in charge" using the "F crimped portion" can be entered using a writing instrument or the like.

The date entry area 356a has, for example, a substantially rectangular shape, and its width (longitudinal length) is c=16 mm, for example. The person-in-charge name entry area 356b has, for example, a substantially rectangular shape, and its width (longitudinal length) is d=18 mm, for example. Thus, the longitudinal length of the contact name entry area 356b is longer than the longitudinal length of the date entry area 356a.

The second colored portion 353 has a plurality of areas, including a character area 354 in which first character information 354a is described and a code area 355 in which first code information 355a is described. The first character information 354a is, for example, the management number of the main control board such as "ABCD/12345", but is not limited to this, and other information may be displayed. The first code information 355a is represented by a two-dimensional code such as a QR code (registered trademark) that can read information that can specify the first character information 354a by using a reader. Here, the information that can specify the first character information 354a includes information that completely matches the first character information 354a, and information that specifies the first character information 354a even if it does not completely match the first character information 354a. It is information that can be For example, when the first character information 354a is ABCD/12345, ABCD12345 (no slash), the first character information ABCD-12345 (with a hyphen) when 354a is ABCD12345, ABCD/12345 (without "s") when the first character information 354a is ABCD/12345s ("s" is added regardless of the model) )and so on. In addition, even if there is a difference in uppercase and lowercase letters, a difference in full-width and half-width characters, a difference in font, etc. between the two, even if they do not completely match the first character information 354a, the first character information 35ab may be included in an example of information that can identify the In this embodiment, the first code information 355a is a two-dimensional code such as a QR code (registered trademark), but may be a one-dimensional code other than the two-dimensional code.

For example, as shown in FIG. 18, when the size of the recording paper 350 is e=53 mm and f=83 mm, the size of the first code information 355a is, for example, a= 9 mm and b=9 mm (the ratio of the display area of the first code information 355a to the entire recording paper 350 is about 1.8%). For example, when the size of the recording paper 350 is e=53 mm and f=83 mm, the size of the display area of the first character information 354a is y1=4 mm and x1=4 mm. 25 mm (the area occupied by the first character information 354a with respect to the entire recording paper 350 is about 2.3%). The first code information 355a is formed in a predetermined area of the recording paper 350, such as sa1=7 mm, sb1=67 mm, ta1=7 mm, and tb1=37 mm. .

As described above, the size of the display area of the first code information 355a is set to a=9 mm and b=9 mm, for example. On the other hand, as described above, the size of the display area of the second code information 550a is set to j=6 mm and i=6 mm, for example. Thus, the display area for the first code information 355a is larger in size (area) than the display area for the second code information 550a.

Further, as described above, the occupancy rate of the display area of the first code information 355a with respect to the entire recording paper 350 is, for example, about 1.8%. On the other hand, as described above, the occupancy rate of the display area of the second code information 550a with respect to the entire seal 550 is, for example, about 1.7%. In this way, the occupancy ratio of the display area of the first code information 355 a to the entire recording paper 350 is higher than the occupancy ratio of the display area of the second code information 550 a to the entire sealing sticker 550 .

Also, as described above, the size of the display area of the first character information 750b is set to y1=4 mm and x1=25 mm, for example. On the other hand, as described above, the size of the display area of the second character information 550b is set to y2=2 mm and x2=11 mm, for example. Thus, the display area for the first character information 354a is larger in size (area) than the display area for the second character information 550b.

Further, as described above, the occupancy rate of the display area of the first character information 354a with respect to the entire recording paper 350 is approximately 2.3%. On the other hand, as described above, the occupancy rate of the display area of the second character information 550b with respect to the entire seal 550 is about 1%. In this way, the occupancy ratio of the display area of the first character information 354 a to the entire recording paper 350 is higher than the occupancy ratio of the display area of the second character information 550 b to the entire sealing sticker 550 .

The character region 354 and the code region 355, which are the second colored portion 353, are colored in a rectangular shape. It is gray with a lower brightness than the person's name entry area 356b and white. Thus, the character area 354 and the code area 355 have lower brightness than the seal area 357, the date entry area 356a and the person in charge name entry area 356b. Note that these lightness relationships may be reversed.

By displaying the second colored portion 353 (the first character information 354a and the first code information 355a) in the region with low brightness in this manner, the first colored portion 352 (the seal region 357, the date entry region 356a, the person in charge It is possible to prevent the person who fills in the first name entry area 356b) from filling in the second coloring section 353 in the wrong entry area. That is, in the present embodiment, the first colored portion 352 is filled in after the recording paper 350 is pasted on the substrate case 80, and since it overlaps the main control substrate 63, the main control substrate 63 has a high contrast. It is desirable to make it as bright as possible so that it can be easily noticed by the person filling it out. On the other hand, in the present embodiment, the information (the first character information 354a and the first code information 355a) to be written in the second colored portion 353 is information known before the recording paper 350 is attached to the substrate case 80. , which is information that can be printed by a machine before being pasted. Therefore, the entry in the second coloring section 353 is performed by printing with a machine. Therefore, as described above, in order to make both the first colored portion 352 and the second colored portion 353 more visible with respect to the background color of the main control board 63, both should be white. is the most desirable, but a difference in brightness from the first colored portion 352 is intentionally made so as not to make a mistake in the writing area. In addition, mechanical printing can reduce friction variations.

The first colored portion 352 is preferably filled with a writing instrument or a seal, and the first character information 354a and the first code information 355a displayed in the second colored portion 353 are preferably formed by printing. is. This is because the area with high brightness is more likely to catch the eye of the scribe than the area with low brightness, and the distinction between the first colored portion 352 and the second colored portion 353 becomes clearer, and the area that is easier to catch the eye. This is because it is possible to prevent the entry person from making a mistake in the area to be filled in.

The base of the first colored portion 352 is formed thicker than the base of the second colored portion 353 . This is because, in the present embodiment, the second colored portion 353 is filled in before the recording paper 350 is attached to the substrate case 80 , so the second colored portion 353 is more difficult to fill in than the first colored portion 352 . Since there is no need to consider writing with a writing instrument or the like, there is no need to form the first colored portion 352 thickly. On the other hand, since the first colored portion 352 is an area that can be written with a writing instrument or the like, it is formed thick to give flexibility. I'm trying Therefore, when an operator writes with a writing instrument or the like, it becomes difficult to peel off even if there is strong friction with the writing instrument. In addition, since writing on the first colored portion 352 is performed after the recording paper 350 is pasted on the hard substrate case 80, it is possible to facilitate writing by providing flexibility. In addition, when the first colored portion 352 is formed thick, it can easily absorb the ink of the writing instrument.

Further, when the first character information 354a and the first code information 355a displayed in the second colored portion 353 are formed by printing, it is necessary to dry the second colored portion 353 quickly after printing. This is because it is possible to improve work efficiency by making the thickness thinner. Here, the base of the first colored portion 352 may be formed thicker than the base of the second colored portion 353 by foil stamping, foil stamping after printing, double printing, varnishing after printing, or the like. good.

In addition, it is desirable to print the second colored portion 353 on the recording paper 350 after the first colored portion 352 is printed. This is because, as described above, the first colored portion 352 has a thicker base than the second colored portion 353, so that the print is difficult to dry and the time required for the print to dry is ensured. The order of printing the first colored portion 352 and the second colored portion 353 may be the same, or the first colored portion 352 may be printed after the second colored portion 353 is printed. may

Also, the recording paper 350 may be attached to a portion overlapping with a part of various electronic components arranged on the main control board 63 when viewed from the side facing the main control board 63 housed in the board case 80. good. In this case, the color of the characters formed on the recording paper 350 is a color that provides high contrast not only to the background color of the main control board 63 but also to the model number characters printed on the electronic components. It is desirable that Also, even in this case, the recording paper 350 overlaps the parts that are arranged inside the board case 80 and need to be visually inspected from the outside of the board case 80, such as the main CPU 61 among various electronic parts. It is desirable that the tape is attached so as not to overlap the area (inspection area), the area (fraud prevention area) that overlaps with the parts for preventing fraudulent actions on the substrate case 80, various crimped portions, and the like. Therefore, in this embodiment, the recording paper 350 does not overlap the inspection area and the fraud prevention area of the surface 80M of the substrate case 80 (the front surface of the substrate case 80 when viewed from the front of the substrate case 80), and is colored black. It is attached to a portion facing the main control board 63 on which the formed IC chip group is arranged. In other words, the recording paper 350 is affixed so as not to overlap the inspection area and the fraud prevention area, and as a result, is affixed to the overlapping portion of the IC chip group formed in black.

In the recording paper 350, when the recording paper 350 is viewed from the back surface opposite to the front surface on which characters related to the regular opening history of the board case 80, the first code information 355a, the first character information 354a, etc. are displayed by printing or the like, , the characters related to the normal opening history of the substrate case 80, the two-dimensional code forming the first code information 355a, the characters forming the first character information 354a, etc. are seen through so that a person can determine their orientation. As a result, when the recording paper 350 is pasted before the main control board 63 and the board case 80 are assembled, the vertical relationship of the recording paper 350 is maintained from the back when fixing the main control board 63 to the cover member 80 a of the board case 80 . can be confirmed, and the main control board 63 can be fixed to the cover member 80a without making a mistake in the mounting direction of the main control board 63 to the cover member 80a. Note that the first code information 355a may be transparent from the back surface of the recording paper 350 to the extent that it can be read by a reader.

(Affixing recording paper and sealing stickers to the substrate case)
Next, attaching the recording paper 350 and the sealing seal 850 to the substrate case 80 will be described with reference to FIG.

The sealing seal 550 is attached to the surface 80M of the board case 80 (the front surface of the board case 80 when the board case 80 is viewed from the front) so as to be exposed to the outside of the board case 80 . In this embodiment, a part of the sealing seal 550 is located at the uneven boundary between the fitting portion 80a4 of the cover member 80a and the first fitting formation portion 80b9a of the fitting portion 80b9 of the base member 80b. The surface 80a4a of the fitting portion 80a4 and the surface 80b9a1 of the first fitting formation portion 80b9a of the fitting portion 80b9 are attached so as to come together (see FIGS. 6, 19, and 21). At this time, as shown in FIG. 21, the direction of the two-dimensional code forming the second code information 550a and the direction of the characters forming the second character information 550b are the left side of the board case 80 when the board case 80 is viewed from the front. to the right (“right” direction: positive direction of the x-axis).

The recording paper 350 is located on the front surface 80M of the board case 80, and is positioned so as to overlap the main control board 63 when viewed from the side facing the main control board 63 housed in the board case 80 (when viewed from the front of the board case 80). , it is attached to the outside of the substrate case 80 so as to be exposed. In this embodiment, the recording paper 350 is attached to the front surface 85a1a of the main portion 85a of the front plate 80a1 of the cover member 80a (see FIGS. 6, 19 and 21). At this time, as shown in FIG. 21, the direction of the two-dimensional code forming the first code information 355a and the direction of the characters forming the first character information 354a are the upper side of the board case 80 when the board case 80 is viewed from the front. is a direction downward from ("downward" direction: negative direction of the z-axis).

As described above, when the certificate stamp 750 is attached to the lower panel 35 of the front door 3 of the slot machine 1, the direction of the two-dimensional code forming the third code information 750a and the characters forming the third character information 750b is a direction from the upper side to the lower side of the slot machine 1 (“down” direction: negative direction of the z-axis) when viewed from the front of the slot machine 1 (see FIG. 1).

Note that the orientation of the two-dimensional code forming the first code information 355a of the recording paper 350, the orientation of the characters forming the first character information 354a, and the orientation of the two-dimensional code forming the third code information 750a of the certificate stamp 750 or the direction of the characters constituting the third character information 750b is the direction from the upper side to the lower side of the board case 80 or the slot machine 1 described above (the "downward" direction: the negative direction of the z-axis), the sealing seal 550 The orientation of the two-dimensional code forming the second code information 550a and the orientation of the characters forming the second character information 550b are in the direction from the left side to the right side of the substrate case 80 (“right” direction: positive direction of the x-axis). In addition, the direction from the bottom to the top of the substrate case 80 (“upward” direction (positive direction of the z-axis)) may be different from the direction of the two-dimensional code and characters of the recording paper 350 and the certificate stamp 750 .

Further, as shown in FIG. 19, the distance from the hinge mechanism 4 is smaller for the sealing sticker 550 than for the recording paper 350 (the sealing sticker 550 is closer to the hinge mechanism 4 than the recording paper 350). Further, as shown in FIG. 19, the distance from the hinge mechanism 4 is smaller for the second code information 550a on the sealing sticker 550 than for the first code information 355a on the recording paper 350 (the first code information 355a on the recording paper 350 is The second code information 550a of the seal 550 is closer to the hinge mechanism 4 than the seal 550). By doing so, when the front door 5 is opened, the recording paper 350 having substantially the same contents of the code information and the contents of the character information is more likely to be printed than the sealing sticker 550 having substantially the same contents. By making the first code information 355a on the recording paper 350 easier for a fraudulent person to read, the second code information on the sealing sticker 550 is more difficult to read.

As shown in FIG. 19, the recording paper 350 and the sealing sticker 550 attached to the surface 80M of the substrate case 80 are closer to the substrate case than the sealing sticker 550 when the substrate case 80 is viewed from the front. It is near the center of 80. Further, as shown in FIG. 19, when the board case 80 is viewed from the front, the first code information 355a is arranged closer to the center of the board case 80 than the second code information 550a. Note that the board case 80 has, for example, a rectangular shape when viewed from the front of the board case 80, and the rectangular shape here includes not only a perfect square but also a shape having irregularities.

Specifically, as shown in FIG. 19, the center line L3C of the horizontal length (lateral width) L3 of the entire surface 80M of the board case 80 and the vertical length of the entire surface 80M of the board case 80 Assuming that the intersection point of the center line L4C of (longitudinal width) L4 is a reference point Q, the center point T of the first code information 355a is closer to the reference point Q than the center point S of the second code information 550a.

From another point of view, as shown in FIG. Assuming that the point of intersection of the vertical length (longitudinal width) L2 of the area of the surface 80M on which a sticker or the like can be pasted and the center line L2C is the reference point P, the center point S of the second code information 550a is placed at the intersection of the center line L2C. The center point T of the 1-code information 355a is closer to the reference point P. Here, the "region where a sticker or the like can be pasted" is, for example, a region that does not overlap with a crimping portion, a connector portion, or the like when viewed from the front of the board case 80 .

Although the central point of the code information has been described, the central point U of the entire recording paper 350 may be closer to the reference point Q than the central point R of the entire sealing sticker 550, or the reference point P may be close to .

Further, as described above, the center point U of the entire recording paper 350 and the center point R of the entire sealing sticker 550 are used. Although the center point is determined by , it is not limited to this center point. For example, if the overall shape of the recording paper 350 or the sealing sticker 550 is not a simple square shape but a distorted shape combining cloud shapes and elliptical shapes, the center point can be easily determined. In such a case, the distance from the code information or the location closest to the reference point Q or reference point P described above to the reference point Q or reference point P on the recording paper 350 or the sealing sticker 550 It is also possible to compare with For example, even if the point closest to the reference point Q in the first code information 355a is closer to the reference point Q than the point closest to the reference point Q in the second code information 550a good. Further, even if the point closest to the reference point P in the first code information 355a is closer to the reference point P than the point closest to the reference point P in the second code information 550a good. The point closest to the reference point Q on the recording paper 350 may be closer to the reference point Q than the point closest to the reference point Q on the sealing sticker 550 . Also, the point closest to the reference point P on the recording paper 350 may be closer to the reference point P than the point closest to the reference point P on the sealing sticker 550 .

Further, the first code information 355a is arranged closer to the center in the left-right direction of the substrate case 80 when viewed from the front than the second code information 550a, and the recording paper 350 is arranged closer to the recording paper 350 than the sealing sticker 550. You may make it arrange|position near the center in the left-right direction.

Further, as shown in FIG. 21, when the substrate case 80 is accommodated in the housing 3 of the slot machine 1, the first code information 355a of the recording paper 350 and the second code information 550a of the seal 550 are When the board case 80 is viewed from the front, they are not aligned vertically or horizontally. In other words, the first code information 355a of the recording paper 350 and the second code information 550a of the sealing sticker 550 are the same when the board case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1 when viewed from above. There is no overlapping area between the first code information 355a and the second code information 550a (in the vertical direction), and when the substrate case 80 in this state is viewed from the left side (in the horizontal direction), the first code information 355a and the second code information 550a There is no overlapping area with the 2-code information 550a. This makes it difficult for a fraudulent person to continuously read the first code information 355a on the recording paper 350 and the second code information 550a on the sealing sticker 550. It is possible to eliminate the time margin for reading both of the second code information 550a.

When the board case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1, the recording paper 350 is more likely to move forward than the sealing sticker 550 in the direction from the rear side to the front side of the slot machine 1 ("front side"). ] direction: the negative direction of the y-axis). More specifically, when the substrate case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1, the first code information 355a and the first character information 354a of the recording paper 350 are the same as the seal 550. From the second code information 550a, the second character information 550b, etc., in the direction from the rear side to the front side of the slot machine 1 (“forward” direction: negative direction of the y-axis), on the front side (y-axis direction negative side) placed.

By making the positions of the first code information 355a on the recording paper 350 and the second code information 550a on the seal 550 different in the front-rear direction of the slot machine 1, a fraudulent person can easily obtain the first code information 355a and the second code information 550a. It takes time to adjust the focus of the reader when reading 550a. It is possible to avoid giving time to read the second code information 550a of the seal 550 whose content is substantially different. In particular, by placing the sealing sticker 550 in which the contents of the code information and the contents of the character information are not substantially the same is located on the rear side (positive side in the y-axis direction) of the recording paper 350, The first code information 355a of the recording paper 350 whose information content and character information content are substantially the same is read before the second code information 550a of the sealing sticker 550 whose content is substantially different. can be motivated.

Code information such as a one-dimensional code and a two-dimensional code such as a QR code (registered trademark) (hereinafter referred to as “board surface code information” as appropriate) is arranged on the mounting surface 63 of the main control board 63 . Sometimes. As the board surface code information, the code information directly arranged on the mounting surface 63 and the top surface of the components (main CPU 61, IC chip, etc.) mounted on the mounting surface 63a There is code information placed on the surface and the surface on the opposite side). In this case, in a state where the substrate case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1, the direction from the rear side to the front side of the slot machine 1 (“forward” direction: negative direction of the y-axis)). , the board surface code information is arranged on the front side (negative side in the y-axis direction) of the second code information 550a of the sealing sticker 550, and the first code information 355a of the recording paper 350 is arranged more than the board surface code information. may also be arranged on the front side (negative side in the y-axis direction).

The gate marks 80ag of the cover member 80a and the gate marks 80bg of the base member 80b are such that when the substrate case 80 is viewed from the front, the distance between the first code information 355a and the gate marks 80ag is the same as that of the substrate case 80 of the base member 80. It is formed so as to be larger than the distance between the portion overlapping the first code information 355a and the gate mark 80bg when viewed from the front. This prevents the gate mark 80ag from interfering with the reading of the first code information 355a. In addition, since the gate marks 80ag do not interfere with the reading of the first code information 355a, it is possible for the fraudulent person to read the first code information 355a of the recording paper 350 whose content of the code information and the content of the character information are substantially the same. It can motivate you to read. The uniformity of the injection molding may be maintained by providing more gate traces 80ag on the cover member 80a than the gate traces 80bg on the base member 80b.

When the substrate case 80 is viewed from the front, the sealing seal 550 has unevenness between the fitting portion 80a4 of the cover member 80a and the first fitting formation portion 80b9a of the fitting portion 80b9 of the base member 80. It is attached to the surface 80a4a of the fitting portion 80a4 and the surface 80b9a1 of the first fitting formation portion 80b9a of the fitting portion 80b9 so as to come to the boundary portion where the breaking portion 80a4h is located. In this embodiment, the boundary portion has unevenness, but the present invention is not limited to this. A specific example of attaching the seal 550 will be described with reference to FIGS.

In the specific example of FIG. 20( a ), the sealing seal 550 has a portion of the second code information 550 a that is part of the fitting portion 80 a 4 of the cover member 80 a and the fitted portion of the base member 80 when viewed from the front of the substrate case 80 . The surface 80a4a of the fitting portion 80a4 and the fitted portion 80b9 are arranged so that the second character information 550b is not located at the boundary portion 80ab1 with the first fitting forming portion 80b9a of the fitting portion 80b9. is attached to the surface 80b9a1 of the first fitting formation portion 80b9a. At this time, when the cover member 80a and the base member 80b are separated, the breaking portion 80a4h breaks the second code information 550a but does not break the second character information 550b. In this way, since a part of the second code information 550a is positioned at the uneven boundary portion 80ab1, the fraudulent person is given the impression that the reading of the second code information 550a is difficult, and the contents of the code information and the characters are different from each other. It can be motivated to read the first code information 355a of the recording paper 350 having substantially the same information content. In addition, by preventing the second character information 550b from being positioned at the boundary portion 80ab1 and intentionally preventing the second character information 550b from being broken, even if the second character information 550b is replaced with a forged seal after being illegally opened. can be easily found. Further, by breaking the second code information 550a to make it unreadable and making it impossible to check the relationship with the second character information 550b, it is possible to create an erroneous imitation. Further, the second code information 550a can be reliably broken by the breaking portion 80a4h. Note that the arrangement example of FIG. 20A can be applied even when there is no breaking portion 80a4h.

Further, the substrate case 80 may be provided with a structure (breaking portion) that facilitates the formation of such traces. For example, by providing a cavity to which the sealing seal 550 does not stick between the flange of the base member 80b and the flange of the cover member 80a, even if the sealing seal 550 is to be broken with a knife or the like, the sealing seal 550 bends and breaks cleanly. You can leave it out. Further, the substrate case 80 is provided with a sealing seal cover member that covers the portion to which the sealing seal 550 is attached, and the sealing seal 550 cannot be broken unless the sealing seal cover member is slid and removed. A projection that scratches the sealing seal 550 when the sealing seal cover member is slid and removed may be provided on the inner side of the cover member and on the side that contacts the sealing seal. By configuring in this way, even if a person who tries to commit fraud tries to break the sealing seal 550 so as not to leave a trace, it is possible to leave a trace.

In the specific example of FIG. 20(b), the sealing seal 550 has both the second code information 550a and the second character information 550b when viewed from the front of the substrate case 80. The surface 80a4a of the fitting portion 80a4 and the base are arranged so that the fitting portion 80b9 is not positioned on the uneven boundary portion 80ab1 with the first fitting forming portion 80b9a, and a part of the other portion is located on the boundary 80ab1. It is attached to the surface 80b9a1 of the first fitting formation portion 80b9a of the fitting portion 80b9 of the member 80. As shown in FIG. At this time, when the cover member 80a and the base member 80b are separated, the breaking portion 80a4h is in a position where neither the second code information 550a nor the second character information 550b is broken, but other parts are broken. As a result, both the second code information 550a and the second character information 550b of the sealing sticker 550 are not deformed such as unevenness, and the sealing sticker 550 does not give a sense of incongruity to the fraudulent person. It is possible to prevent the motivation to read the second code information 550a of the sealing sticker 550 whose character information is not substantially the same. In addition, when an authorized operator (the hall side or the manufacturer side) opens the circuit board case 80 for no illegal purpose, the second code information 550a and the second character information 550b are not broken and can be reused. Even so, the functions of the second code information 550a and the second character information 550b can be maintained. Note that the arrangement example of FIG. 20(b) can be applied even when there is no breaking portion 80a4h.

Therefore, according to the above-described embodiment, while making the content of the first character information 354a displayed on one recording paper 350 substantially the same as the content of the identifiable information obtained from the first code information 355a, By making the content of the second character information 550b displayed on the other sealing sticker 550 different from the content of the information obtained from the second code information 550a, when the first code information 355a on one side is read, the By recognizing that the content of the one-character information 354a and the content of the identifiable information obtained from the read first code information 355a are substantially the same, the content of the other second character information 550b and the second It is possible to make a person who intends to commit a fraudulent act create a counterfeit substrate case 80 having an erroneous seal 550 on the surface 80M by tricking the person into thinking that the content of the information obtained from the code information 550a is substantially the same. can. As a result, it is possible to effectively prevent fraudulent acts related to the substrate case 80 having the recording paper 350 and the sealing seal 550 on the surface 80M.

In addition, when a store clerk checks, it is troublesome to check whether a character string of 9 or 8 digits matches the list. The content of the identifiable information obtained from the 1-code information 355a is substantially the same, and the content of the second character information 550b displayed on the seal 550 and the content of the information obtained from the second code information 550a are substantially the same. A counterfeit board case can be easily found by a simple confirmation method of confirming whether it is different. As a result, it is possible to effectively prevent fraudulent acts related to the substrate case 80 having the recording paper 350 and the sealing seal 550 on the surface 80M.

Further, the first code information 355a from which information that can specify the first character information 354a is obtained is arranged closer to the center of the substrate case 80 than the second code information 550a from which information different from the second character information 550b is obtained. Thus, the first code information 355a can be read by a reader more easily than the second code information 550a for a fraudulent person who tries to make a counterfeit of the board case 80. FIG. As a result, the fraudulent person first reads the first code information 355a, and the content of the first character information 354a is substantially the same as the content of the identifiable information obtained from the read first code information 355a. By recognizing that there is, it is possible to induce the belief that the content of the second character string information 750a and the content of the information obtained from the second code information are substantially the same.

Also, the size of the first code information 355 a on the recording paper 350 is larger than the size of the second code information 550 a on the seal 550 . Therefore, since the first code information 355a is more visible than the second code information 550a, the fraudster can be motivated to read the first code information 355a before the second code information 550a. Also, since the first code information 355a of the recording paper 350 has a higher occupation rate than the second code information 550a of the sealing sticker 550, similarly, the fraudulent person reads the first code information 355a before the second code information 550a. can be motivated. Also, since the size of the first character information 354a of the recording paper 350 is larger than that of the second character information 550b of the seal 550, similarly, the fraudulent person will receive the second character information 550b before the second code information 550a paired with the second character information 550b. It can be motivated to read the first code information 355a paired with the first text information 354a. In addition, since the first character information 354a of the recording paper 350 has a higher occupation rate than the second character information 550b of the sealing sticker 550, similarly, the fraudulent person is given priority over the second code information 550a paired with the second character information 550b. can be motivated to read the first code information 355a paired with the first character information 354a. (1) the size of the first code information 355a of the recording paper 350 is larger than that of the second code information 550a of the sealing sticker 550; (3) the first character information 354a of the recording paper 350 is larger than the second character information 550b of the seal 550; (4) the first character information 354a of the recording paper 350 is the seal 550 is higher than the second character information 550b, the fraudulent person can be further motivated to read the first code information 355a before the second code information 550a.

Also, the recording paper 350 on which the content of the code information and the content of the character information are substantially the same are arranged so as to face each other, and the sealing seal 550 to seal the one whose information is not substantially the same is arranged so as not to face them. By arranging them, the first code information 354 a of the recording paper 350 is easier to read than the second code information 355 a of the sealing sticker 550 . Therefore, the fraudster can be motivated to read the first code information 354a before the second code information 355a.

Further, while the contents of the third character information 750b displayed on one of the certificate stamps 750 and the contents of the identifiable information obtained from the third code information 750a are substantially the same, the contents of the information displayed on the other seal 550 are the same. By making the content of the second character information 550b different from the content of the information obtained from the second code information 550a, when reading the third code information 750a on one side, the content of the first character information 750b is read. It will be recognized that the contents of the identifiable information obtained from the third code information 750a are substantially the same. Therefore, the content of the second character information 550b on the other side and the content of the information obtained from the second code information 550a are substantially the same. A counterfeit substrate case 80 with 550 can be made. As a result, it is possible to effectively prevent fraudulent acts related to the substrate case 80 having the sealing seal 550 on the surface 80M.

In addition, when the store clerk inspects, it is troublesome to check whether the character string of 9 or 8 digits matches the list. The content of the identifiable information obtained from the code information 750a is substantially the same, and the content of the second character information 550b displayed on the seal 550 is different from the content of the information obtained from the second code information 550a. A counterfeit board case can be easily found by a simple confirmation method of confirming whether the board case is a counterfeit product. As a result, it is possible to effectively prevent fraudulent acts related to the substrate case 80 having the sealing seal 550 on the surface 80M.

Further, the third code information 750a from which information that can specify the third character information 750b is arranged outside the housing 3 of the slot machine 1, and the second code information 550a from which information different from the second character information 550b can be obtained. By arranging it in the housing 3, it is possible to make the third code information 750a easier to read by a reader than the second code information 550a to a fraudulent person who tries to make an imitation of the substrate case 80. can. As a result, the fraudulent person first reads the third code information 750a, and the content of the first character information 354a is substantially the same as the content of the identifiable information obtained from the read first code information 355a. By recognizing that there is, it is possible to induce the belief that the content of the second character string information 750a and the content of the information obtained from the second code information are substantially the same.

Also, the size of the third code information 750 a on the certificate stamp 750 is larger than the size of the second code information 550 a on the seal 550 . Therefore, the third code information 750a is more visible than the second code information 550a, which motivates the fraudster to read the third code information 750a before the second code information 550a. Also, since the third code information 750a of the certificate stamp 750 has a higher occupation rate than the second code information 550a of the seal 550, similarly, the fraudulent person is instructed to read the third code information 750a before the second code information 550a. can be motivated. Also, since the size of the third character information 750b of the certificate stamp 750 is larger than that of the second character information 550b of the seal 550, similarly, the fraudulent person will receive the second character information 550b before the second code information 550a paired with the second character information 550b. It can be motivated to read the third code information 550a paired with the three-letter information 750b. In addition, since the third character information 750b of the certificate stamp 750 has a higher occupation rate than the second character information 550b of the sealing sticker 550, similarly, the fraudulent person will receive the second character information 550b before the second code information 550a paired with it. It can be motivated to read the third code information 750a paired with the third text information 750b. (1) the third code information 750b of the certificate stamp 750 is larger than the second code information 550a of the seal 550; (3) The third character information 750b of the certificate stamp 750 is larger than the second character information 550b of the seal 550. (4) The third character information 750b of the certificate stamp 750 is the second character of the seal 550. Having a higher occupancy than information 550b can further motivate a fraudster to read the third code information 750a before the second code information 550a.

In addition, the certificate stamp 750 having substantially the same content of the code information and the content of the character information are arranged so as to face each other, and the sealing seal 550 whose information is not substantially the same is arranged so as not to face each other. Therefore, the third code information 750a of the certificate stamp 750 is easier to read than the second code information 355a of the seal 550. Therefore, the fraudster can be motivated to read the third code information 750a before the second code information 355a.

The present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, the following may be used.

The LEDs (such as the monitor LED 32 and the LEDs of the ratio indicator 69) mounted on the mounting surface of the main control board 63 are the second code information 355a of the sealing sticker 550 rather than the second code information 355a of the sealing sticker 550 when viewed from the front of the board case 80. 1 code information 355a (when viewed from the front of the board case 80, the distance between the LED and the first code information 355a is smaller than the distance between the LED and the second code information 550a) good. As a result, by directing the fraudulent person's consciousness toward the recording paper 350, the fraudulent person can see the first code information 355a of the recording paper 350 in which the content of the code information and the content of the character information are substantially the same. can motivate you to read In this case, it is preferable that the LED is not arranged in a predetermined area near the first code information 355a on the recording paper 350. FIG. For example, the predetermined area in which the LEDs are not arranged is set to an area where the LEDs interfere with the reading of the first code information 355a to some extent under predetermined circumstances. 355a may be a region 34a (see FIG. 22(a)), or a region 34b obtained by combining the region 34a that overlaps with the first code information 355a and a region 34b1 extending from the region 34a to the outside of one LED. Also (see FIG. 22(b)), an area 34c is obtained by combining an area 34a overlapping with the first code information 355a and an area 34c1 extending from the area 355a to the outside of one two-dimensional code constituting the first code information 355a. (see FIG. 22(c)). As a result, it is possible to prevent the LED from excessively hindering reading of the first code information 355a on the recording paper 350 by an authorized operator.

Code information (board surface code information) such as a one-dimensional code or a two-dimensional code such as a QR code (registered trademark) may be arranged on the mounting surface 63 of the main control board 63 . As the board surface code information, the code information directly arranged on the mounting surface 63 and the top surface of the components (main CPU 61, IC chip, etc.) mounted on the mounting surface 63a There is code information placed on the surface and the surface on the opposite side). In this case, the substrate surface code information may not be arranged in a predetermined area near the first code information 355a on the recording paper 350. FIG. For example, the predetermined area in which the board surface code information is not arranged is set to an area where the LED hinders reading of the first code information 355a to some extent under a predetermined situation. may be (1) is an area that overlaps with the first code information 355a when the substrate case 80 is viewed from the front. (2) is an area obtained by combining an area overlapping with the first code information 355a and an area extending from the area to the outside of half of the two-dimensional code forming the first code information 355a when viewed from the front of the substrate case 80. . (3) is an area obtained by combining an area overlapping with the first code information 355a and an area extending from the area to the outside of one two-dimensional code forming the first code information 355a when viewed from the front of the substrate case 80. . As a result, the authorized operator can smoothly read the first code information 355a of the recording paper 350 without being disturbed by the substrate surface code information.

Further, substrate surface code information may exist in a predetermined area near the second code information 550 of the sealing sticker 550 . For example, the area where the board surface code information exists is set to an area where the LED hinders the reading of the second code information 550a to some extent under a predetermined situation. It may be an area from outside the half of the two-dimensional code forming the second code information 550a in the area overlapping the information 550a to outside the one two-dimensional code. This makes it difficult for an unauthorized person to read the second code information 550a by hindering the board surface code information.

Further, when the substrate case 80 is viewed from the front, the distance between the first code information 355a on the recording paper 350 and the substrate surface code information closest to the first code information 355a is the same as the first code information 355a on the recording paper 350 and the sealing seal. 550 may be smaller than the distance from the second code information 550a. Even if a fraudulent person tries to read other code information after reading the first code information 355a of the recording paper 350, it is possible to read the board surface code information without any problem even if it is read. It is possible to guide the person, thereby delaying the reading of the second code information 550 a of the seal 550 .

Also, in a front view of the substrate case 80, the first code information 355a and the second code information 550a are on a straight line connecting the first code information 355a of the recording paper 350 and the second code information 550a of the sealing sticker 550. The substrate surface code information may be present between. As a result, after the fraudulent person reads the first code information 355a of the recording paper 350, the fraudulent person can be guided to read the board surface code information next, and the second code information of the sealing sticker 550 can be guided. We can delay getting to the reading of 550a. The fact that the board surface code information exists on a straight line connecting the first code information 355a and the second code information 550a means that, for example, when the board case 80 is viewed from a certain direction, the first code information 355a and the board surface It is sufficient that the code information and the second code information 550a overlap at least partially at the same time.

In addition, among the components mounted on the mounting surface 63a of the main control board 63, the tallest component (mounting surface 63a to the top surface of the component (the surface opposite to the surface facing the mounting surface 63a among the component surfaces) ) may not be arranged in a predetermined area near the first code information 355 a on the recording paper 350 . The tallest component is, for example, an aluminum capacitor 91a or a regulator 91b (see FIG. 6). For example, the predetermined area in which the tallest component is not arranged is set to an area where the tallest component interferes with the reading of the first code information 355a to some extent under predetermined circumstances, for example, the following (1 ) to (2). (1) is an area from the area overlapping the second colored portion 353 where the first code information 355a is displayed to the outside of half of the two-dimensional code forming the first code information 355a when viewed from the front of the substrate case 80. be. (2) is the area from the area overlapping the second colored portion 353 where the first code information 355a is displayed to the outside of one two-dimensional code forming the first code information 355a when viewed from the front of the substrate case 80. be. This prevents the tallest part from becoming an obstacle when reading the first code information 355a on the recording paper 350, so that the authorized operator can smoothly read the first code information 355a. Become.

In addition, the tallest component may be arranged so that the entirety of the component overlaps with the second colored portion 353 where the first code information 355a is displayed when the substrate case 80 is viewed from the front. . As a result, even when the tallest component is near the first code information 355a on the recording paper 350, the tallest component becomes an obstacle when reading the first code information 355a on the recording paper 350. Therefore, it becomes possible to smoothly read the first code information 355a by a legitimate worker.

Further, the substrate case 80 is arranged on the front side of the fitting portion 80a4 of the cover member 80a and the first fitting forming portion 80b9a of the fitting portion 80b9 of the base member 80 in a front view of the substrate case 80. For example, as shown in FIG. 23, a substantially box-shaped seal cover portion 900 having an open rear side may be provided. In this case, when the substrate case 80 is viewed from the front, the front side of the sealing seal 550 is covered with the sealing seal cover portion 900, and the sealing seal cover portion 900 can read the second code information 550a with a reader, and the second character information 550b may have transparency to the extent that a person such as an operator can distinguish characters. In this case, the recording paper 350 (first code information 355a, first character information 354a) is arranged so as to be exposed outside the substrate case 80, while the sealing sticker 550 (second code information 550a, second character information 550b) is arranged so that the front side of the substrate case 80 in the front view is covered with the sealing seal cover portion 900 . The structure of the sealing seal cover portion 900 is an example, and any structure that can cover the front side of the sealing seal 550 in the front view of the substrate case 80 may be used. As a result, by covering the front side of the second code information 550a of the sealing sticker 550 whose contents of the code information and the contents of the character information are not substantially the same, the reading of the second code information 550a is made difficult and illegal. It is possible to prevent the actor from discovering that the content of the second code information 550a of the seal 550 and the content of the second character information 550b are not substantially the same. The sealing seal cover portion 900 is made of, for example, transparent resin (for example, transparent ABS resin (acrylonitrile, butadiene, styrene, etc.) in the same manner as the cover member 80a and the base member 80b. The transparency of the sealing seal cover portion 900 is lower than that of the cover member 80a and the base member 80b, although the second code information 550a can be read. By doing so, it is possible to make it difficult to read the second code information 550a.As a method of reducing the transparency, a resin material with relatively low transparency is selected.For example, the cover member 80a and the base are selected. When the member 80b is made of PC, ABS resin, which is generally considered to be less transparent than PC, may be used for the sealing seal cover portion 900. Further, a transparent resin material may be mixed with a pigment to increase transparency. It may be lowered and used for the sealing seal cover portion 900. Further, the injection mold used for forming the sealing seal cover portion 900 may be subjected to surface roughening such as providing fine irregularities, for example, in the second code information 550a. , and the roughened injection mold may be used to manufacture the sealing seal cover portion 900. In addition, a gate The sealing seal cover portion 900 may be made to form traces, push pins, etc. that are inevitable during molding.

In addition, as shown in FIG. 23, the sealing seal cover part 900 is located in the vicinity of the second code information 550a of the sealing seal 550 and does not overlap with the second code information 550a when viewed from the front of the substrate case 80. A target structure 900a (for example, a rib extending in the front-rear direction) may be provided. In this case, the three-dimensional structure 900a interferes with the reading of the second code information 550a, and the fraudulent person's motivation to read the second code information 550a can be reduced.

In addition, the sealing seal 550 is continuous from the first flat surface portion of the surface 80M of the substrate case 80 and the flat surface of the entire surface of the substrate case 80 (such as the surface 80M and side surfaces) and is the same as the flat surface. Affixed to the substrate case 80 so that the second code information 550a is located on the first surface, spanning a plurality of surfaces including at least the second surface that is not on a flat surface (regardless of shape such as flat or curved surface). may be made. At this time, the second character information 550b may also be arranged on the first surface. For example, as shown in FIGS. 24(a) and 24(b), the sealing seal 550 is continuous from the flat first surface portion of the surface 80M of the substrate case 80 and is not on the same plane as the substrate case. The second code information 550a and the second character information 550b may be arranged on the flat first surface of the surface 80M of the substrate case 80, straddling the second surface of the left side of the substrate case 80. FIG. In the case of FIG. 24, the entire encapsulation seal 550 is not attached to the surface 80M of the substrate case 80. In the case of FIG. 24A is a front view of the board case 80, and FIG. 24B is a left side view of the board case 80. FIG. This reduces the willingness of the fraudulent person to read the second code information 550a and the like of the seal 550, and does not hinder the work of reading the second code information 550a and the like of the seal 550 by authorized workers. can be done.

Moreover, the components mounted on the mounting surface 63a of the main control board 63 may be SMDs (surface mount devices). For example, when a double-sided mounting component (lead insertion type: for example, a DIP (Dual In-line Package) component) 99A is mounted on the mounting surface 63a of the main control board 63, the shape of the terminal 99A1 of the double-sided mounting component 99A causes double-sided mounting. A gap YY is formed between the component 99A and the mounting surface 63a (see FIG. 26(a)). On the other hand, when an SMD (for example, SOP (Small Outline Package) or QFP (Quad Flat Package)) 99B is mounted on the mounting surface 63a of the main control board 63, due to the shape of the terminal 99B1 of the SMD 99B, the SMD 99B and the mounting surface 63a Almost no gap is formed between (see FIG. 26(b)). As a result, the first code information 355a of the recording paper 350 and the top surface of the double-sided mounting component 99A (the surface of the mounting component opposite to the surface facing the mounting surface 63a) are perpendicular to the mounting surface 63a. From the distance XX in the direction, the mounting surface 63a between the first code information 355a of the recording paper 350 and the top surface of the SMD 99B (the surface of the mounted component opposite to the surface facing the mounting surface 63a). The distance ZZ in the vertical direction is larger, and the SMD 99B can be prevented from interfering with the reading of the first code information 355a on the recording paper 350. FIG.

2, when the board case 80 is placed above the housing 3 of the slot machine 1, the sealing seal 550 is positioned as shown in FIG. The recording paper 350 may straddle the boundary between the member 80a and the base member 80b and be arranged on the upper surface side of the housing 3 in the surface 80M of the substrate case 80. FIG. Here, the upper part of the housing 3 is shaded by the top plate of the housing 3 and the like, and becomes dark. For this reason, the sealing seal 550 in which the contents of the code information and the contents of the character information are not substantially the same is arranged at a darker position inside the housing 3 than the recording paper 350 in which the contents are substantially the same. Therefore, the fraudulent person can be motivated to read the first code information 355a of the recording paper 350 whose contents are substantially the same.

Further, in the above-described embodiment, the recording paper 350 is arranged closer to the “B crimped portion” than the sealing sticker 550 , but the present invention is not limited to this. 550 side may be arranged so as to be close to the "B crimped portion".

In addition, the surface 80M of the board case 80 is provided with a portion indicating the pasting position of the recording paper 350. For example, a predetermined shape is provided at each of the four corners of the pasting position of the recording paper 350, and the board case 80 is attached to the slot machine 1. , the relevant portion may be arranged on the opposite side of the hinge mechanism 4 with respect to the sealing seal 550 (in the order of arrangement of the hinge mechanism 4, the sealing seal 550, and the portions).

In addition, the sealing sticker 550 is made to deteriorate more easily than the recording paper 350 (easier to yellow and peel off) than the recording paper 350. (see) may be arranged closer (the distance between the sealing sticker 550 and the vent 3h may be smaller than the distance between the recording paper 350 and the vent 3h). An example of the material of the sealing seal 550 is paper.

Also, the connectors arranged on the main control board 80 housed in the board case 80 may be arranged around the sealing seal instead of around the recording paper 350 . In addition, when the substrate case 80 is attached to the housing 3 of the slot machine 1, at least the sealing seal 550 around the sealing seal 550 is located on the mounting surface 63a of the main control substrate 63 when the substrate case 80 is viewed from the front. A connector may be provided in the upper portion, and no connector may be provided in at least the upper portion of the recording paper 350 in the periphery of the recording paper 350 . As a result, the first code information 355a of the recording paper 350, in which the wiring cable does not interfere with reading, rather than the second code information 550a in the sealing sticker 550, in which the wiring cable connected to the connector interferes with reading, is used by the fraudulent person. Motivate yourself to read.

In the above-described embodiment, when the board case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1, the recording paper 350 is stronger than the sealing sticker 550, and the first code information of the recording paper 350 355a, the first character information 354a, etc., are more forward than the second code information 550a, the second character information 550b, etc. (negative direction of )), but is not limited to this. The positional relationship between the code information 355a, the first character information 354a, etc. and the second code information 550a, the second character information 550b, etc. : in the negative direction of the y-axis), the opposite may be true.

Also, the LEDs (such as the monitor LED 32 and the LED of the ratio indicator 69) are closer to the second code information 550a of the sealing sticker 550 than the first code information 355a of the recording paper 350 when the substrate case 80 is viewed from the front. (the distance between the LED and the second code information 550a is smaller than the distance between the LED and the first code information 355a when the board case 80 is viewed from the front). Thus, the reading of the second code information 550a of the seal 550 by an unauthorized person can be obstructed by the LED. In this case, it is preferable that the LED is not arranged in a predetermined area near the second code information 550a of the sealing sticker 550. FIG. For example, the predetermined area in which the LED is not arranged is set to an area where the LED excessively interferes with the reading of the second code information 550a under a predetermined situation, for example, the following (1) to (3). may (1) is a region that overlaps with the second code information 550a when the board case 80 is viewed from the front. (2) is an area obtained by combining an area overlapping with the second code information 550a and an area extending from the area to the outside of one LED when the board case 80 is viewed from the front. (3) is an area obtained by combining an area overlapping with the second code information 550a and an area extending from the area to the outside of one two-dimensional code constituting the second code information 550a when viewed from the front of the substrate case 80. . Accordingly, it is possible to prevent the LED from excessively hindering reading of the second code information 550a of the seal 550 by an authorized operator.

In addition, the contents of the above-described embodiment and the above-described modification are based on a substrate case that accommodates a control substrate other than the main control substrate 63 (for example, a sub-control substrate 73 attached to the left inner wall surface of the housing 3: see FIG. 2). It can also be applied by adding changes as appropriate.

Further, the contents of the above-described embodiment and the above-described modifications can be combined as appropriate.

Moreover, although the slot machine 1 has been described above as an example, the present invention is not limited to this, and can be applied to other gaming machines such as a pachinko machine.

A counterfeit board case having an erroneous second display part on the surface can be made by a person, and illegal acts related to the board case having the first display part and the second display part on the surface can be effectively prevented. In addition, when inspecting by a regular worker, it is troublesome to check whether the character string of 9 or 8 digits matches the list. The content and the content of the identifiable information obtained from the first code information are substantially the same, and the content of the second character information displayed on the second display unit and the content of the information obtained from the second code information are substantially the same. A counterfeit board case can be easily found by a simple confirmation method of confirming whether it is different from the board case. Can effectively prevent fraudulent activities related to

It is possible to make a person create a counterfeit board case having the wrong second display portion on the surface, and effectively prevent fraudulent acts related to the board case having the second display portion on the surface. In addition, when an authorized worker inspects, it is troublesome to check whether the character string of 9 or 8 digits matches the list. The content and the content of the identifiable information obtained from the third code information are substantially the same, and the content of the second character information displayed on the second display unit and the content of the information obtained from the second code information are substantially the same. A counterfeit board case can be easily found by a simple confirmation method of confirming whether it is different, and from this point as well, fraudulent acts related to a board case equipped with a second display part on the surface are effective. can be effectively prevented.

(5) The first display section is provided with characters related to the regular opening history of the board case, and the color of the characters is a color that has a high contrast with the ground color of the surface of the circuit board facing the first display section. It can be assumed that This makes it easier for the operator to visually recognize the characters related to the regular opening history of the board case.

(6) The first display section has a colored first area in which the operator writes predetermined information and a colored second area in which the first code information is displayed. The brightness may be different from the second area. By doing so, the worker can enter the predetermined information in the first area without making a mistake. If the brightness of the first area is made higher (brighter) than that of the second area, the operator can enter the predetermined information in the first area without mistakes.

(7) The first display unit has a substantially rectangular date entry area and a person in charge name entry area for entering the date and the name of the person in charge, respectively. The length may be greater than the longitudinal length of the date entry area. By doing so, it becomes possible to respond flexibly to the entry of the name of the person in charge, which may vary in length compared to the date, and to respond to the globalization of store clerks who may visit in the future.

It may be a direction from the bottom to the right (horizontal) or a direction from the bottom to the top (vertically rotated by 180°).

In the case of (23) and (25), the first code information of the first display unit having substantially the same code information content and character information content faces the person, and the information is substantially the same. Since the second code information on the second display portion, which is not the same in terms of the two, does not face each other, the first code information is easier to read than the second code information 355a, and the fraudulent person can read the second code information earlier than the second code information. It can be motivated to read the first code information.

In the case of (24) and (25), the third code information of the third display unit having substantially the same content of the code information and the content of the character information faces the person, and the information is substantially the same. Since the second code information on the second display section, which is not the same as the other, does not face directly, the third code information is easier to read than the second code information, and the fraudulent person is notified of the second code information before the second code information. It can be motivated to read the 3-code information.

(26) The orientation of the characters that make up the first character information on the first display unit is the direction from the upper side to the lower side (vertical orientation) when the substrate case is viewed from the front side (when viewed from the front of the substrate case). ).

(27) The orientation of the characters forming the third character information on the third display portion is from the upper side to the lower side when the gaming machine is viewed from the front side of the gaming machine (when viewed from the front of the gaming machine). (portrait orientation).

(28) When the board case is viewed from the surface side (when viewed from the front of the board case), the direction of the characters that make up the second character information on the second display unit is set to a direction other than the direction from the top to the bottom, for example, the left side. It may be a direction from the bottom to the right (horizontal) or a direction from the bottom to the top (vertically rotated by 180°).

In the case of (26) and (28), the first character information of the first display unit having substantially the same code information content and character information content faces the person, and the information is substantially the same. Since the second character information on the second display section, which is not physically the same, does not face each other, the first character information is easier to read than the second character information, and the fraudulent person can see the second character information and the paired second character information. It can be motivated to read the first code information paired with the first character information before the two code information.

In the case of (27) and (28), the third character information of the third display unit having substantially the same content of the code information and the content of the character information faces the person, and the information is substantially the same. Since the second character information on the second display section, which is not physically the same, does not face each other, the third character information is easier to read than the second character information, and the fraudulent person can see the second character information and the paired character information. It can be motivated to read the third code information paired with the third character information before the two code information.

(29) The second display portion is positioned so that the second code information includes a portion of the boundary portion between the cover member and the base member that is not on the same plane, and the second character information indicates that the cover member and the base member are not on the same plane. It is displayed so that it is located outside the boundary of the In this way, the deformation of the second code information gives the fraudulent person the impression that it is difficult to read the second code information, and the content of the code information and the content of the character information are substantially the same. The first code information on the display may be motivated to read before the second code information on the second display whose contents are not substantially the same. In addition, by preventing the second character information from being broken, even if a forged second display portion is displayed after the cover member and the base member are illegally separated, it can be easily detected.

(30) In the second display portion, neither the first code information nor the second character information of the second display portion is positioned at the boundary between the base member and the cover member, and other portions are positioned at the boundary. so that it appears. In this way, both the second code information and the second character information on the second display section are not deformed, and the second display section does not give a sense of incongruity to the fraudulent person. It is possible to prevent the motivation to read the second code information of the second display unit whose character information contents are not substantially the same. Also, if an authorized worker separates the cover member and the base member of the circuit board case for no illegal purpose, the second code information and the second character information are not broken and are reused. can also maintain the functions of the second code information and the second character information.

(31) When the cover member and the base member are separated, the substrate case may be provided with a breaking portion that breaks the second code information but does not break the second character information. In this way, the second code information can be reliably broken by the breaker, making it impossible to read the second code information. An imitation of the second display section on which information is displayed is produced.

(32) When the substrate case is attached to the back plate of the housing of the gaming machine and housed inside the gaming machine, the first display section (first code information, first character information) and the second display section (Second code information, second character information) may be located at different positions in the direction from the rear side to the front side of the gaming machine. By doing so, it takes a long time to adjust the focus of the reader when reading the first code information and the second code information, and the fraudulent person can read the code information and the character information that are substantially the same. After reading the first code information of one display portion, it is possible to avoid giving time to read the second code information of the second display portion whose contents are substantially different.

(33) In the above (32), the first display portion (first code information, first character information) is behind the gaming machine than the second display portion (second code information, second character information). It may be on the front side in the direction from the side to the front side. In this way, the fraudulent person can receive the first code information on the first display unit whose content of the code information and the content of the character information are substantially the same, and the second display whose content is substantially different. It can be motivated to read ahead of the second code information of the part.

(34) In (33) above, the fourth code information is present on the surface of the circuit board facing the first display portion, and the fourth code information is present in the direction from the rear side to the front side of the game machine. The code information may be on the front side of the second code information on the second display portion, and the first code information on the first display portion may be on the front side of the fourth code information. As a result, the first code information, the fourth code information, and the second code information can be formed to be easily read in this order, motivating the first code information to be read, and making it difficult to read the second code information.

Each corner of the outer circumference is rounded, and the R value of the R chamfering of the first display portion is smaller than the R value of the R chamfering of the second display portion (for example, the R chamfering of the first display portion is R0 .3 mm and the R chamfer of the second display portion is R2 mm). In the case of transparent stickers, fingerprints, etc., left during the pasting work can be confused with traces of fraud (traces of fraud such as peeling off the transparent sticker, drilling a hole in the substrate case, and attaching the transparent sticker again). . The smaller the R, the smaller the contact area of the finger, etc., and the lower the adhesive force, as well as preventing the adhesion of fingerprints and foreign substances adhering to the finger. In that case, it is desirable that R is small. On the other hand, if the R is large, the working efficiency of the pasting work is improved. Therefore, regarding the second display portion formed by the opaque seal, there is no above-mentioned adverse effect due to adhesion of fingerprints and the like, so workability should be prioritized. desirable. Also, the second display portion may be provided with a slit, and in this case, it is desirable to give priority to workability.
