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

The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine having enhanced security against fraudulent acts on a substrate case or the like.

In order to achieve the above object, the gaming machine according to the present invention is provided with a main control means for controlling the progress of the game in the gaming machine, and includes a main control board housed in a board case. The means includes display control means for controlling the display of a plurality of types of game history data on the display, and the display is mounted on one side of the main control board on which the main control means is mounted. It is housed in a board case so as to be visible from the outside, and a plurality of first terminals for handling signals directly related to either the advantage of the game or the acquisition of the game medium are arranged on the one side of the main control board. The first terminal of the plurality of first terminals arranged on the one surface of the main control board is located between the first terminal closest to the display and the display. The display is mounted on a first component in which one terminal is not arranged, or on the one side of the main control board, a plurality of second components in which the first terminal is not arranged at least on the display side. It is characterized by the fact that the vessel is surrounded.
In order to achieve the above object, the game machine according to the present invention is a game machine provided with a board case for accommodating a circuit board for controlling the operation of the game machine between a cover member and a base member facing each other. A first display unit and a second display unit are provided on the surface of the case, and the first display unit reads the first character information and information that can identify the first character information by using a reader. Is displayed, and the second display unit displays the second character information, which is character information different from the first character information, and the second character information can be obtained by using a reader. Second code information that can read different information is displayed, and when the board case is viewed from the front side, the first code information is more than the second code information. The feature is that it is located near the center of. The first display unit and the second display unit are not limited to printing on the surface of the substrate case, and may be provided on the surface of the substrate case to which the sticker is attached.

According to this configuration, the content of the first character information displayed on one first display unit and the content of the identifiable information obtained from the first code information are substantially the same, while the other second display. By making the content of the second character information displayed in the section different from the content of the information obtained from the second code information, when one of the first code information is read, it is read as the content of the first character information. By recognizing that the content of the identifiable information obtained from the first code information is substantially the same, the content of the other second character information and the content of the information obtained from the second code information can be changed. It is possible to convince a person who intends to cheat to be substantially the same and to create a counterfeit board case having an erroneous second display on the surface. As a result, it is possible to effectively prevent fraudulent activities related to the substrate case provided with the first display unit and the second display unit on the surface.

In addition, when a clerk inspects, it is complicated to confirm whether a character string such as 9 digits or 8 digits matches the list, but the content of the first character information displayed on the first display unit and the first The content of the identifiable information obtained from the 1-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. The imitation board case can be easily found by a simple confirmation method of confirming whether or not. This makes it difficult to cheat on the substrate case provided with the first display unit and the second display unit on the surface.

Further, by arranging the first code information from which information that can identify the first character information can be obtained from the center of the board case rather than the second code information from which information different from the second character information can be obtained, the board case can be arranged. It is possible to make the first code information easier to read by the reader than the second code information for a fraudster who tries to create a counterfeit product. As a result, the fraudster reads the first code information first 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 assumption that the content of the second character information and the content of the information obtained from the second code information are substantially the same.

Further, although not shown, a character string composed of alphanumeric characters or the like is attached to the mounting surface 63a of the main control board 63 by printing or the like. Here, the characters given to the mounting surface 63a of the main control board 63 include a number indicating the sensor corresponding to the monitor LED 32, a board ID capable of identifying the type and model number of the main control board 63, and the like.

Further, as shown in FIG. 4, caulking portions 80c are formed on the left and right sides of the upper portion of the substrate case 80, and after accommodating the main control substrate 63 and attaching the cover member 80a to the base member 80b, caulking is performed. The cover member 80a and the base member 80b cannot be separated unless the portion 80c is destroyed. In the present embodiment, engaging the cover member 80a and the base member 80b is defined as "A caulking", and the portion (caulking portion 80c) of the substrate case 80 to which "A caulking" is applied is defined as "A caulking portion". Is defined. The "A caulking part" is inside the board case 80 from the time when the slot machine 1 is shipped from the manufacturing factory until the inspection organization of the slot machine 1 opens the board case 80 and inspects the main control board 63. This is a part for sealing the board case 80 so that the main control board 63 is not tampered with, and a trace thereof remains when the board case 80 is tampered with. The place where the "A caulking part" is provided and the number of the "A caulking part" are not particularly limited.

Further, a rotation shaft 80ax (see FIGS. 4 and 5) is set in the left-right direction (positive / negative direction of the x-axis) of the lower portion of the substrate case 80, and the substrate case 80 can rotate about the axis. Further, as shown in FIG. 5, the support plate 81 is provided with a case holding portion 81a so that the board case 80 can be held in the direction in which the main control board 63 faces forward. As shown in FIG. 5, the case holding portion 81a protrudes forward, and an insertion hole 81b through which the tip of the case knob 83 (see FIG. 4) is inserted is provided at the front end portion. The case knob 83 is fixed to the substrate case 80, and when the tip is inserted into the insertion hole 81b, the case knob 83 is locked to the case holding portion 81a, and when pulled, the locked state is released, and the case knob 83 is detachable from the case holding portion 81a. It has become.

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 axis. As shown in FIG. 5, when the board case 80 is rotated about 90 ° from the holding state and the board case 80 is tilted forward, the surface of the main control board 63 opposite to the mounting surface 63a becomes visible, and an abnormality occurs in the surface. You can check if you are doing it.

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, and a right inner plate 80a2 extending at approximately 90 ° with respect 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 fitting portion 80a4 having a step with a front plate 80a1 on the left side of the left inner plate and the left outer plate. The front surface (front surface) 80a4a of the fitting portion 80a4 is on the positive direction side of the y-axis (rear side of the slot machine 1 (rear side of the slot machine 1) with respect to the front surface (front surface) 85a1a of the main portion 85a described later of the front plate 80a1. Located on the back side)). Further, in the vicinity of the left side surface of the surface 80a4a, a sealing seal 550 described later attached to the surface 80a4a and the surface 80b9a1 described later is a protruding portion that breaks when the cover member 80a and the base member 80b are separated. 80a4h is formed. The structure of the fractured portion 80a4h is not particularly limited.

The front plate 80a1 has a main portion 85a arranged substantially parallel to the mounting surface 63a of the main control board 63, and a first recess 85b, a second recess 85c, and a second recess 85a recessed toward the mounting surface 63a with respect to the main portion 85a, respectively. It has 3 recesses 85d. The first recess 85b is formed at a position on the mounting surface 63a including the position directly above the main CPU 61 in a state where the main control board 63 is housed, and restricts the movement of the first recess 85b in the direction directly above the main CPU 61. In this embodiment, the 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 recess 85c is adjacent to the left side of the first recess 85b, and is formed at a position adjacent to the substrate case 80 in the front view (the viewpoint in the positive direction of the y-axis in FIG. 6), and is mainly used by the staff of a game store. It is a part to look into the main CPU 61 when confirming fraud using the CPU 61. At the bottom of the third recess 85d, an insertion hole 85e through which the connector 68 mounted on the main control board 63 is inserted is formed.

As shown in FIG. 6, the base member 80b of the board case 80 faces the surface of the main control board 63 opposite to the mounting surface 63a, and the board case 80 is held by the support plate 81. A rear plate 80b1 abutting on 81, a right side plate 80b2 extending at approximately 90 ° with respect to the rear plate 80b1, an intermediate plate 80b3, a left side plate 80b4, a lower side plate 80b5, a base left outer plate 80b8, and a left side plate 80b4. 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 accommodation space), and the outer surface of the base left outer plate 80b8 outside the left side plate 80b4 (opposite to the accommodation space). A left rotation shaft portion 90b is formed on the side surface). The right rotation shaft portion 90a is supported by the right bearing hook 81c (see FIG. 14) provided on the support plate 81. Further, the left rotation shaft portion 90b is supported by the left bearing hook 81d (see FIG. 14) provided on the support plate 81.

A plurality of cover locking pieces 80b6 are formed at the front end of the portion recessed on the rear plate 80b1 side of the lower plate 80b5. It bends at 90 ° and is 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 the forward movement of the cover member 80a is restricted. Will be done. This prevents the cover member 80a from rising, which is that the cover member 80a is separated from the base member 80b to the front side.

The fitted portion 80b9 is recessed in the positive direction side of the y-axis (rear side (back side) of the slot machine 1) with respect to the first fitted forming portion 80b9a and the first fitted forming portion 80b9a. It has a second fitting forming 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 recess of the fitted portion 80b9 of the base member 80b. In this state, the boundary portion between the fitting portion 80a4 and the first fitting forming portion 80b9a of the fitting portion 80b9 is uneven. The seal seal 550 is attached so that a part thereof is located at the uneven boundary portion 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. Without it, the cover member 80a and the base member 80b cannot be separated.

Next, the rotation mechanism of the substrate case 80 will be described with reference to FIGS. 7 to 15. Note that FIG. 7 is a partially disassembled perspective view of the substrate case 80 held by the support plate 81, and is a perspective view of the substrate case 80 when viewed from diagonally above right. Further, FIG. 8A is a view when the rotating member cover 86 is viewed from the front, FIG. 8B is a diagram when the rotating member cover 86 is viewed from the rear, and FIG. 9 is a view when the bearing member 87 is viewed from the front. A perspective view when viewed from diagonally above right, FIG. 10 is a perspective view of the shaft fixing member 88, and FIG. 11 is a perspective view when the cover member 80a is viewed from diagonally lower front right, which is an enlarged view of the right outer plate 80a3. 12A and 12B are enlarged views of the right outer plate 80a3 when viewed from the rear, and FIG. 13 is a perspective view of the base member 80b when viewed from diagonally below the front right, and is an enlarged view of the right rotating 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, as viewed from diagonally lower front right, and FIG. 15 is B- of FIG. B is a cross-sectional view taken along the line B and is an enlarged view of the 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-handed rotating 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. One end of the shaft portion 90a1 is connected to the right side plate 80b2, and the central axis of the cylinder is arranged so as to be 90 ° with respect to the right side plate 80b2, forming a part of the rotating 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 the rotating member cover 86 described later can be inserted.

Further, on the peripheral surface of the shaft portion 90a1, two arrangement holes 90a3 in which the movement restricting projection 88a (see FIG. 10) of the shaft fixing member 88 is arranged are formed. Further, a locking piece 90a4 is formed on the peripheral edge of each of the two arrangement holes 90a3. Each of the locking pieces 90a4 projects inward from the other end edge of the shaft portion 90a1 in the arrangement hole 90a3 in the inner direction of the arrangement hole 90a3. Further, a cutting line 90a5 is recessed between the other end of the shaft portion 90a1 and the arrangement hole 90a3, and the locking piece 90a4 can be removed by cutting the line.

Further, the flange portion 90a2 is formed at a position separated from the right side plate 80b2 by a predetermined distance. A plate-shaped 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 movement of the substrate case 80 in the left-right direction can be restricted. ing. Further, a locking projection 90a6 is formed on the outer peripheral surface of the shaft portion 90a1, and after the shaft portion 90a1 is inserted into the insertion hole 87c (see FIG. 9) of the bearing portion 87b, the locking projection 90a6 and the flange portion are formed. The bearing portion 87b of the bearing member 87 is sandwiched between the 90a2 and the bearing member 87 so that the movement of the substrate case 80 in the left-right direction can be restricted.

As shown in FIG. 9, the bearing member 87 abuts on the support plate 81 and is bent at approximately 90 ° from the fixed portion 87a in which a screw hole for fixing to the support plate 81 is formed and the end portion of the fixing portion 87a. It also has a bearing portion 87b in which an insertion hole 87c through which the shaft portion 90a1 of the right rotation shaft portion 90a is inserted is formed. The insertion hole 87c is formed with a diameter larger than the diameter of the outer peripheral circle of the shaft portion 90a1, and the shaft portion 90a1 can be inserted and rotated.

As shown in FIG. 10, the shaft fixing member 88 includes a cylindrical portion 88d, a movement restricting protrusion 88a projecting from the outer peripheral surface of the cylindrical portion 88d, and a flange portion formed at one end of the cylindrical portion 88d in the axial direction. It has an 88b and an unused hole indicating piece 88c that projects in the flange portion 88b in the axial direction of the cylindrical portion 88d and in the direction of the other end of the cylindrical portion 88d. The outer peripheral circle of the cylindrical portion 88d is formed with a diameter smaller than the diameter of the inner peripheral circle of the right rotating shaft portion 90a formed on the base member 80b, and one end of the cylindrical portion 88d is formed on the right rotating shaft portion 90a. It can be inserted into the shaft portion 90a1.

Further, the flange portion 88b is formed in a size larger than the diameter of the inner peripheral circle of the right rotation shaft portion 90a, and is also formed in a size larger than the diameter of the insertion hole 87c of the bearing member 87. Therefore, after inserting one end of the cylindrical portion 88d inside the shaft portion 90a1, the leftward movement of the cylindrical portion 88d is restricted by the flange portion 88b.

Further, in the movement restricting projection 88a of the shaft fixing member 88, after one end of the cylindrical portion 88d is inserted into the shaft portion 90a1 of the right rotating shaft portion 90a and fixed by the movement restricting projection 88a, the substrate case 80 is a bearing. It is designed so that it does not come off from the member 87. Specifically, the movement restricting protrusion 88a is formed so that the protrusion height increases from one end of the insertion side of the cylindrical portion 88d toward the other end side where the flange portion 88b is formed, and the movement restricting protrusion 88a is formed. At the other end of the above, 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 until the movement restricting protrusion 88a fits into the arrangement hole 90a3, the movement of the shaft fixing member 88 in the left direction is restricted by the movement restricting protrusion 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 has become.

Therefore, in this embodiment, the substrate case 80 is intentionally removed from the bearing member 87 only once so that the normal rotatable state can be restored again. For example, a case where the movement restricting protrusion 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, if the cutting lines 90a5 formed above and below the letter "B" are cut with a tool, the locking pieces 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 substrate case 80 is fixed to the bearing member 87 again, it can be fixed again by arranging the movement restricting projection 88a in the arrangement hole 90a3 arranged next to the letter "C" of the shaft portion 90a1.

As shown in FIG. 14, when the substrate case 80 and the bearing member 87 are fixed to each other, the bearing portion 87b of the bearing member 87 becomes an obstacle and the movement restricting projection 88a is difficult to see. Therefore, it is unknown which of the arrangement holes 90a3 the movement restricting projection 88a is arranged. However, in a state where the movement restricting protrusion 88a is arranged in the arrangement hole 90a3 next to the letter "B", the unused hole indicator piece 88c hides the cutting lines 90a5 provided above and below the letter "C". Therefore, if the exposed cutting line 90a5 is cut, the locking piece 90a4 of the arrangement hole 90a3 in which the movement restricting projection 88a is arranged can be reliably removed.

Further, as shown in FIG. 14, when the movement restricting protrusion 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. The flange portion 88b of the member 88 is arranged so as 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 substrate case 80 is fixed, the substrate case 80 can be removed by removing the bearing member 87 from the support plate 81. It is not possible.

Further, these rotating mechanism portions are covered with a rotating member cover 86, and the rotating mechanism portion cannot be accessed unless the rotating member cover 86 is removed. As shown in FIG. 8B, the rotating member cover 86 is formed with a rotating side locking portion 86b when viewed from the rear side, and the rotating member cover 86 is once formed on the support plate 81 for rotation. When the side locked portion 89 (see FIG. 7) and the rotating side locking portion 86b are engaged with each other, the rotating member cover 86 cannot be removed unless they are destroyed.

Here, the rotation-side locked portion 89 of the support plate 81 is provided at only one position, but has a structure capable of sliding in the vertical direction. Therefore, for example, the rotating member cover 86 provided at two locations is engaged with one of the rotating side locking portions 86b (lower rotating side locking portion 86b), and then the one rotating side. After the locking portion 86b is destroyed, the rotating side locked portion 89 is slid upward and engaged with the other rotating side locking portion 86b (upper rotating side locking portion 86b) again. 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 the sealing structure can be released by cutting the line with a tool or the like. It has become.

By the way, as a method of mounting the lid member 80a to the base member 80b, after fixing the main control board 63 to the cover member 80a with screws 30, the cover member 80a and the base member 80b are overlapped with each other, and then the cover member 80a is attached. The cover member 80a is attached to the base member 80b by sliding it downward (see FIG. 6). Then, as described above, after the cover member 80a is attached to the base member 80b, the substrate case 80 is tightly sealed by the caulking portion 80c, and if the caulking portion 80c is not destroyed, the base member 80b and the cover member 80a Can no longer be separated. Further, since the right outer plate 80a3 and the left outer plate of the cover member 80a are both mounted in a state of being arranged inside the base member 80b, once the cover member 80a is mounted on the base member 80b, the cover member 80a is mounted. The movement of the cover member 80a in the left-right direction is restricted. Further, since the cover member 80a is also restricted from moving in the forward direction by the cover locking piece 80b6 formed on the base member 80b, the cover member 80a is once separated from the base member 80b in order to separate the cover member 80a from the base member 80b. Need to slide upwards.

However, in this embodiment, the shaft fixing member 88 that fixes the rotation shaft of the substrate case 80 can regulate the slide movement of the cover member 80a upward. 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 broken, the rotating member cover 86 is further removed and the shaft is further fixed. The cover member 80a and the base member 80b cannot be separated unless the member 88 is removed. The structure will be described below.

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

Regarding the mounting method of the rotating member cover 86, as shown in FIG. 7, after arranging the bearing member 87 at a predetermined position of the support plate 81, the substrate case 80 is rotated clockwise in the insertion hole 87c of the bearing member 87. The shaft portion 90a1 of the shaft portion 90a is inserted, and the bearing member 87 is fixed with a screw. Subsequently, the substrate case 80 is fixed by the shaft fixing member 88.

FIG. 15 is a cross-sectional view taken along the line BB of FIG. 14, in which the shaft fixing member 88 is inserted into the bearing member 87, and the fixing pin 86a of the rotating member cover 86 is further inserted into the cylindrical portion 88d of the shaft fixing member 88. 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 substrate case 80. The tip of the shaft fixing member 88 (the end of the cylindrical portion 88d opposite to the flange portion 88b) is a cover-side notch 80a6 formed in the right outer plate 80a3 of the cover member 80a, and an intermediate plate of the base member 80b. It is in a state of being inserted into each of the base side notches 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. As a result, the shaft fixing member 88 is fixed by the fixing pin 86a. As shown in FIG. 8B, the fixing pin 86a is inside the rotating member cover 86, and is the shaft of the cylindrical portion 88d of the shaft fixing member 88 and 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 and moves 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. As described above, the shaft fixing member 88 has a function of preventing the board case 80 from being illegally removed from the support plate 81 (so-called housing caulking) and a function of preventing the board case 80 from being illegally opened (so-called body caulking). ), And both caulking functions are integrated on the rotation shaft of the substrate case 80. In general, it is desirable to protect the structural part (caulking structure part) that realizes such a caulking function with a case or the like in order to block unauthorized access from the outside. However, if both caulking functions are provided at separate locations, it becomes necessary to protect them in individual cases, which not only occupies the space inside the housing but also increases the cost. Therefore, if both caulking functions are integrated on the rotating shaft as in this embodiment, the installation range of the case for protecting the caulking structure portion can be small, and space efficiency is good.

Therefore, even if the crimped portion 80c of the substrate case 80 is broken, it is not easy to separate the cover member 80a and the base member 80b when they are fixed to the support plate 81. As described above, the sealing structure between the cover member 80a and the base member 80b of the substrate case 80 is also possible on the rotation mechanism side. The fixing pin 86a of the rotating member cover 86 inserts the cylindrical portion 88d of the shaft fixing member 88 and the notch 80a6 on the cover side 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 with the substrate case 80 is defined as "B caulking", and the portion of the substrate case 80 to which "B caulking" is applied (rotating side of the rotating member cover 86). A portion of the locking portion 86b, which is composed of a rotating side locking portion 86b on the negative side in the z-axis direction in FIG. 8 and a rotating side locked portion 89 of the support plate 81) is referred to as a “B caulking portion”. Is defined as. The "B caulking portion" is formed by connecting 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 a part for leaving a trace when the support plate 81 is illegally removed. When inspecting the board case 80 and the support plate 81, whether or not the board case 80 has been illegally removed from the support plate 81 by checking the "B caulking portion" and its surroundings (presence or absence of destruction marks, etc.). Can be confirmed. The place where the "B caulking portion" is provided is not particularly limited.

The rotation-side locked portion 89 of the support plate 81 constituting the "B caulking portion" is provided only at one location, but has a structure capable of sliding in the vertical direction, so that the "B caulking portion" can be formed. After the engagement is disengaged by breaking the rotating side locking portion 86b on the negative side in the z-axis direction of FIG. 8, which is one of the rotating side locking portions 86b of the rotating member cover 86, the upper part Move in the direction. As a result, the rotating side locking portion 86b on the positive side in the z-axis direction of FIG. 8, which is one of the rotating side locking portions 86b of the rotating member cover 86, and the rotating side locked portion 89 of the support plate 81. Becomes engageable. This engagement is defined as "C caulking", and the portion of the substrate case 80 to which "C caulking" is applied (one of the rotating side locking portions 86b of the rotating member cover 86) is positive in the z-axis direction in FIG. A portion composed of a rotating side locking portion 86b on the side, a rotating side locked portion 89 of the support plate 81, and the like) is defined as a “C caulking portion”.

In the present embodiment, in addition to the "B caulking portion", a "C caulking portion" is provided as a spare for the "B caulking portion". That is, the substrate case 80 may be officially removed from the support plate 81 by an on-site inspection by an inspection organization or the like even after the slot machine 1 is shipped from the manufacturing factory. At the time of this inspection, the above-mentioned "B caulking part" will be officially destroyed by an inspection organization or the like. During this inspection, the rotating side locking portion 86b on the negative side in the z-axis direction of FIG. 8, which is one of the rotating side locking portions 86b of the rotating member cover 86 constituting the "B caulking portion", was destroyed. However, the rotating side locked portion 89 of the support plate 81 is not destroyed and is used as a part of the "C caulking portion". The substrate case 80 after the inspection by the inspection organization or the like is completed needs to be attached to the support plate 81 again, but the rotating member cover 86 constituting the “B caulking portion” of the rotating side locking portion 86b. On the other hand, the rotating 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.

Here, the information that can be read by using the two-dimensional code with a reader is not limited to random alphanumeric characters, but is partially different from the second character information 550b, for example, "87654331". You may. When the second character information 550b is partially 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 described in the second character information 550b. It is difficult to notice the difference from the characters, and it can be mistaken for the same. In the present embodiment, the second code information 550a 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 for the second code information 550a, for example, when the size of the seal seal 550 is, for example, h = 35 mm and g = 60 mm, as shown in FIG. 17, the size of the display area of the second code information 550a is, for example, , J = 6 mm, i = 6 mm (the occupancy rate of the display area of the second code information 550a with respect to the entire sealing seal 550 is about 1.7%). Further, in the second character information 550b, for example, when the size of the seal seal 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, x2 =. Something that is set to 11 mm (the occupancy rate of the display area of the second character information 550b with respect to the entire sealing seal 550 is about 1%) is included. Further, the position of the second code information 550a on the seal seal 550 is sa2 = 47 mm, sb2 = 7 mm, ta2 = 18 mm, tb2 = 11 mm, and the second code information 550a is formed in a predetermined region of the seal seal 550. ..

As described above, the size of the display area of the third code information 750a is set to, for example, n = 7 mm and m = 7 mm. On the other hand, as described above, the size of the display area of the second code information 550a is set to, for example, j = 6 mm and i = 6 mm. As described above, the display area of the third code information 750a has a larger size (area) than the display area of 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 sealing seal 550 is, for example, about 1.7%. 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 higher than the occupancy rate of the display area of the second code information 550a with respect to the entire seal seal 550.

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

The second code information 550a may not be transparent to the extent that it can be read by a reader from the back surface of the seal seal 550.

(Recording paper)
Subsequently, 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, each corner of the outer circumference of the recording paper 350 is chamfered with, for example, R0.3 mm. Here, it is desirable that the recording paper 350 is formed of a resin such as polyethylene terephthalate (PET) and is uncolored. It is not necessary that each corner of the outer circumference of the recording paper 350 is chamfered.

As described above, each corner of the outer circumference of the sealing seal 550 is chamfered with R2 mm, for example, while each corner of the outer circumference of the recording paper 350 is chamfered with R0.3 mm, for example. .. As described above, the value of the chamfering R of each corner of the outer circumference of the recording paper 350 is smaller than the value of the chamfering R of each corner of the outer circumference of the sealing sticker 550. Here, the recording paper 350 is formed of a transparent sticker, and the sealing sticker 550 is made of an opaque sticker. In the case of a transparent sticker, fingerprints etc. attached during the pasting work will be confused with traces of fraud (traces of fraud such as peeling off the transparent sticker and making a hole in the board case and sticking the transparent sticker again). .. The smaller the R, the smaller the contact area of the finger, etc., which not only reduces the adhesive strength but also prevents the adhesion of fingerprints and foreign matter attached to the finger. Therefore, in the case of a transparent sticker such as recording paper 350, the R is Smaller is desirable. On the other hand, if R is large, the work efficiency of the sticking work is improved. Therefore, it is desirable to give priority to workability for the opaque sticker such as the seal sticker 550 because the above-mentioned adverse effects due to the adhesion of fingerprints and the like are not observed. Further, since the sealing seal 550 is provided with slits 558a and 558b, it is desirable to give priority to workability.

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

Further, the color of the characters related to the regular opening history of the substrate case 80 formed on the recording paper 350 is the background color of the main control board 63 (for example, the mounting surface 63a of the surface of the main control board 63 facing the recording paper 350). A color that has high contrast is used with respect to the ground color of. Further, the color having high contrast is a color having a large difference in brightness at the boundary between the outline of the character and the ground color, for example, white when the color of the solder resist which is the ground color of the main control board 63 is green or black. It is a similar color to white and white. Further, the color of the characters related to the regular opening history of the substrate case 80 formed on the recording paper 350 is a color having a high contrast with the ground color of the main control substrate 63, but the color having such a high contrast is This color has a higher contrast than the contrast between the ground 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 the surface 80M of the substrate case 80, and is said to be the same when viewed from the side facing the main control substrate 63 housed in the substrate case 80 (in the front view of the substrate case 80). It is attached at a position where it overlaps with the main control board 63. As a result, the characters related to the regular opening history of the substrate case 80 formed on the recording paper 350 are the surface 80M of the substrate case 80 and viewed from the side facing the main control substrate 63 housed in the substrate case 80 ( (In front view of the board case 80), it exists at a position overlapping with the main control board 63.

The surface 80M of the board case 80, which is a portion that does not overlap with 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), and is a board case. The color of the identification information formed in the second portion 80LD (see FIG. 19), in which the substrate case 80 appears cloudy due to the thickness of the resin constituting the 80 being thicker than that of the thin first portion, appears cloudy. A color having a low brightness with respect to the color of the characters related to the regular opening history of the substrate case 80 formed on the second portion and the recording paper 350, for example, black is used.

Here, the second portion 80LD is a portion that becomes thicker than the first portion and becomes cloudy due to the overlap of the base member 80b and the cover member 80a. For example, as shown in FIG. 19, the second portion 80LD is the left lower end portion of the substrate case 80 in the front view of the substrate case 80. Such a portion looks cloudy due to the overlap of the base member 80b and the cover member 80a. That is, since the substrate case 80 formed of the resin has a characteristic of whitening when plastically deformed, it is not completely transparent, and when a plurality of members of the substrate case 80 overlap, it looks cloudy. It becomes. 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 may be located anywhere as long as the substrate case 80 looks cloudy.

Further, the identification information formed in the second portion 80LD includes not only characters used in languages such as the alphabet, but also numbers and symbols. For example, identification information such as the model number of the board case 80 and the main control board 63. Identification information such as model number is included, but is not limited to this.

Further, the color of the identification information formed in the second part is not limited to black, but is similar to the color similar to black, and the color of the characters related to the regular opening history of the second part 80LD and the substrate case 80 which appear cloudy. Any color that has high contrast may be used.

Further, as an example of the first portion, a portion where the flat plate shape is continuous and the inside thereof is easily visible, for example, a portion facing the ratio indicator 69 or the monitor LED 32 can be mentioned. That is, for example, electronic components such as the ratio display 69 and the monitor LED 32 are formed of a thin flat plate so that they can be visually recognized. Further, it is a part where it is necessary to secure a certain degree of visibility even when the visibility is lowered by attaching something other than the substrate case 80, such as the recording paper 350.

The second portion 80LD in which the substrate case 80 looks cloudy is roughened, for example, by providing fine irregularities on the injection molding die used for forming the cover member 80a or the base member 80b of the substrate case 80. The cover member 80a or the base member 80b may be formed by using the injection molding die that has been subjected to the rough surface processing.

Further, the colors 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 above-mentioned regular opening history of the board case 80 by vertical lines and horizontal lines are also the colors of the substrate formed on the recording paper 350. High contrast with respect to the ground color of the main control board 63 (for example, the ground color of the mounting surface 63a of the surface of the main control board 63 facing the recording paper 350) as well as the color of the characters related to the regular opening history of the case 80. A color that is, for example, white is used. The frame line W1 is formed by a thicker line than the frame line W2.

Further, the color having high contrast is a color similar to the color of characters printed or the like on the mounting surface 80a of the main control board 80 described above. That is, the color of the 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, the similar colors include the same colors.

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

Further, the recording paper 350 includes a light transmitting portion having light transmission and a coloring portion 351 formed of a white base color as the base color. Here, since the light transmitting portion is formed of the recording paper 350 by a sheet having light transmission, characters and borders W1 and W2 related to the regular opening history of the substrate case 80 formed on the coloring portion 351 and the recording paper 350. It becomes a part other than. The colored portion 351 includes a first colored portion 352 having a higher brightness than the second colored portion 353 and a second colored portion 353 having a lower brightness than the first colored portion 352 among the white colors. Here, the brightness refers to the degree of brightness, for example, when the degree of brightness has 10 levels, the first coloring portion 352 is "10", the second coloring portion 353 is "7", and the like. (The larger the value indicating the degree of brightness, the brighter it is).

Here, the brightness of the first coloring portion 352 and the second coloring portion 353 may be different by printing with inks of different colors, or may be different depending on the presence or absence of recoating 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, but both the first colored portion 352 and the second colored portion 352 are used. In order to make the visibility of the main control board 80 good with respect to 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), both are white. Is most desirable.

The first coloring unit 352 includes a plurality of areas, for example, a stamping area 357, a date entry area 356a, and a person in charge name entry area 356b, which are a total of seven areas, provided in the upper right corner of the recording paper 350. The first colored portion 352 is colored in a rectangular shape and is white in the present embodiment.

As described above, the display area of the first character information 354a has a larger size (area) than the display area of 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 about 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 seal 550 is about 1%. 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 higher than the occupancy rate of the display area of the second character information 550b with respect to the entire seal seal 550.

The character area 354 and the code area 355, which are the second coloring parts 353, are colored in a rectangular shape, and in the present embodiment, they are in charge of the marking area 357 and the date entry area 356a, which are the first coloring parts 352 described above. It is a gray color with a lower lightness than the white color with the person name entry area 356b. As described above, the character area 354 and the code area 355 have lower brightness than the stamp area 357, the date entry area 356a, and the person in charge name entry area 356b. The relationship of these lightnesses may be reversed.

By displaying the second coloring portion 353 (first character information 354a, first code information 355a) in the region having low brightness in this way, the first coloring portion 352 (seal inspection area 357, date entry area 356a, person in charge). It is possible to prevent the writer who fills in the name entry area 356b) from mistakenly entering the entry area in the second coloring section 353. That is, in the present embodiment, the entry in the first coloring portion 352 is performed after the recording paper 350 is attached to the substrate case 80 and overlaps with the main control substrate 63, so that the contrast with respect to the main control substrate 63 is high. It is desirable to increase the brightness so that it is easily noticed by the writer. On the other hand, in the present embodiment, the information (first character information 354a, first code information 355a) to be entered in the second coloring unit 353 is information that is known even before the recording paper 350 is attached to the substrate case 80. This is information that can be printed by a machine before it is pasted. Therefore, the entry in the second coloring portion 353 is performed by printing by a machine. Therefore, as described above, in order to improve the visibility of both the first colored portion 352 and the second colored portion 353 with respect to the ground color of the main control substrate 63, both should be white. Is the most desirable, but the difference in brightness from the first coloring portion 352 is intentionally made so that the entry area is not mistaken. Further, in printing by a machine, it is possible to reduce the variation in friction.

It is desirable that the first coloring portion 352 is filled in with a writing tool, a mark, or the like, and the first character information 354a and the first code information 355a displayed on the second coloring portion 353 are preferably formed by printing. Is. This is because the area with high lightness is more likely to be noticed by the writer than the area with low lightness, and the distinction between the first colored portion 352 and the second colored portion 353 is clarified, and the region that is more easily noticed. This is because it is possible to prevent the writer 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 entry in the second colored portion 353 is before the recording paper 350 is attached to the substrate case 80, so that the second colored portion 353 is more expensive than the first colored portion 352. Since it is not necessary to consider writing with a writing tool or the like, it is not necessary to form a thick portion. I am trying to do it. Therefore, when the worker writes with a writing instrument or the like, even if the friction with the writing instrument is strong, it is difficult to peel off. Further, since the entry to the first coloring portion 352 is performed after the recording paper 350 is attached to the hard substrate case 80, it can be easily entered by giving flexibility. Further, when the first coloring portion 352 is formed thick, it is possible to easily absorb the ink of the writing instrument.

Further, when the first character information 354a and the first code information 355a displayed on the second coloring portion 353 are formed by printing, it is necessary to quickly dry the second coloring portion 353 after printing, which is a base. This is because it is possible to improve work efficiency by making the work efficiency thinner. Here, even if the base of the first colored portion 352 is formed thicker than the base of the second colored portion 353 by foil stamping, printing and then foil stamping, printing twice, and varnishing on the printing. good.

Further, it is desirable that the recording paper 350 prints the second colored portion 353 after printing the first colored portion 352. This is because, as described above, the first colored portion 352 has a thicker base than the second colored portion 353, so that the printing is difficult to dry and the time required for the printing to dry is secured. 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. You may.

Further, the recording paper 350 may be attached to a portion that overlaps 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 having high contrast not only for the ground color of the main control board 63 but also for the characters of the model number printed on the electronic components. It is desirable to be done. Further, even in this case, the recording paper 350 is arranged inside the substrate case 80 and overlaps with a component that needs to be visually inspected from the outside of the substrate case 80, for example, a main CPU 61 among various electronic components. It is desirable that the area (inspection area), parts for preventing fraudulent activity on the substrate case 80, and the area (fraudulent activity prevention area) that overlaps with various caulking portions are not overlapped. Therefore, in the present embodiment, the recording paper 350 is black because it does not overlap with the inspection area and the fraud prevention area in the 80M of the surface of the substrate case 80 (the front surface of the substrate case 80 in the front view of the substrate case 80). The formed IC chip group is attached to a portion facing the main control board 63 on which the formed IC chips are arranged. In other words, the recording paper 350 is attached to the overlapping portion of the IC chip group formed in black as a result of being attached so as not to overlap the inspection area and the fraud prevention area.

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 substrate 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 regular opening history of the substrate case 80, the two-dimensional code constituting the first code information 355a, the characters constituting the first character information 354a, and the like can be seen through so that a person can discriminate their orientations. As a result, when the recording paper 350 is attached before assembling the main control board 63 and the board case 80, the vertical relationship of the recording paper 350 is from the back when the main control board 63 is fixed to the cover member 80a of the board case 80. The main control board 63 can be fixed to the cover member 80a without making a mistake in the direction in which the main control board 63 is attached to the cover member 80a. The first code information 355a may be transparent to the extent that it can be read by a reader from the back surface of the recording paper 350.

(Attachment of recording paper and sealing sticker to the board case)
Subsequently, attachment of the recording paper 350 and the sealing sticker 850 to the substrate case 80 will be described with reference to FIG.

The sealing seal 550 is attached to the surface of the substrate case 80 (the front surface of the substrate case 80 in the front view of the substrate case 80) 80M so as to be exposed to the outside of the substrate case 80. In this embodiment, a part of the seal seal 550 is formed at an uneven boundary portion between 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 80b. It is attached to the surface 80a4a of the fitting portion 80a4 and the surface 80b9a1 of the first fitting forming portion 80b9a of the fitting portion 80b9 (see FIGS. 6, 19, and 21). At this time, as shown in FIG. 21, the orientation of the two-dimensional code constituting the second code information 550a and the orientation of the characters constituting the second character information 550b are the left sides of the substrate case 80 in the front view of the substrate case 80. The direction from to the right side ("right" direction: the positive direction of the x-axis).

The recording paper 350 is a position on the surface 80M of the substrate case 80 and overlaps with the main control substrate 63 when viewed from the side facing the main control substrate 63 housed in the substrate case 80 (in the front view of the substrate 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 orientation of the two-dimensional code constituting the first code information 355a and the orientation of the characters constituting the first character information 354a are above the substrate case 80 in the front view of the substrate case 80. The direction from to the bottom ("down" 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 orientation of the two-dimensional code constituting the third code information 750a and the characters constituting the third character information 750b. Is the direction from the upper side to the lower side of the slot machine 1 (“downward” direction: negative direction of the z-axis) in the front view of the slot machine 1 (see FIG. 1).

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

Further, as shown in FIG. 19, the distance from the hinge mechanism 4 of the sealing sticker 550 is smaller than that of 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 in the second code information 550a of the sealing sticker 550 than in the first code information 355a of the recording paper 350 (first code information 355a of the recording paper 350). The second code information 550a of the seal seal 550 is closer to the hinge mechanism 4 than the seal seal 550). In this way, the recording paper 350 in which the content of the code information and the content of the character information are substantially the same when the front door 5 is opened is compared with the sealing sticker 550 in which the contents are not substantially the same. By making it noticeable first, it is possible to make it easier for the fraudster to read the first code information 355a of the recording paper 350 and make it harder to read the second code information of the seal sticker 550.

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

Specifically, as shown in FIG. 19, the center line L3C of the horizontal length (width) L3 of the entire surface 80M of the substrate case 80 and the vertical length of the entire surface 80M of the substrate case 80. (Vertical width) Assuming that the intersection of the center lines L4C of L4 is the 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. 19, the center line L1C of the left-right length (width) L1 of the area 80M of the surface 80M of the substrate case 80 to which the seal or the like can be attached and the substrate case 80. Assuming that the intersection of the vertical length (vertical width) L2 of the surface 80M where a sticker or the like can be attached with the center line L2C is the reference point P, the second code information 550a is higher than the center point S. 1 The center point T of the code information 355a is closer to the reference point P. Here, the "region to which a sticker or the like can be attached" is, for example, a region that does not overlap with a portion that constitutes caulking, an region that does not overlap with a portion that constitutes a connector, and the like in the front view of the substrate case 80.

As described with respect to the center point of the code information, the center point U of the entire recording paper 350 may be closer to the reference point Q than the center point R of the entire seal seal 550, or the reference point P may be used. It 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, but when the recording paper 350 and the sealing sticker 550 are square, diagonal intersections are easily obtained. The center point is determined by, but 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 shape such as a square shape but a distorted shape that is a combination of cloud shapes and elliptical shapes, the center point is easy. In such a case, the distance from the location closest to the above-mentioned reference point Q or reference point P to the reference point Q or reference point P in the code information or the recording paper 350 or the sealing sticker 550. It may be compared with. For example, even if the point closest to the above-mentioned reference point Q in the first code information 355a is closer to the above-mentioned reference point Q than the point closest to the above-mentioned reference point Q in the second code information 550a. good. Further, even if the point closest to the above-mentioned reference point P in the first code information 355a is closer to the above-mentioned reference point P than the point closest to the above-mentioned reference point P in the second code information 550a. good. The point closest to the above-mentioned reference point Q on the recording paper 350 may be closer to the above-mentioned reference point Q than the point closest to the above-mentioned reference point Q on the seal 550. Further, the point closest to the above-mentioned reference point P on the recording paper 350 may be closer to the above-mentioned reference point P than the point closest to the above-mentioned reference point P on the seal 550.

Further, the first code information 355a is arranged closer to the center in the left-right direction in the front view of the substrate case 80 than the second code information 550a, and the recording paper 350 is more than the sealing sticker 550. It may be arranged from the center in the left-right direction.

Further, as shown in FIG. 21, in a state where the substrate case 80 is housed 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 sealing sticker 550 are In the front view of the board case 80, they are not aligned in the vertical direction and the horizontal direction. In other words, the first code information 355a of the recording paper 350 and the second code information 550a of the sealing seal 550 are viewed from above when the board case 80 is attached to the back plate 3a of the housing 3 of the slot machine 1. (In the vertical direction), there is no region where the first code information 355a and the second code information 550a overlap, and when the board 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 355a are the first. 2 There is no area that overlaps with the code information 550a. This makes it difficult for the fraudster to continuously read the first code information 355a of the recording paper 350 and the second code information 550a of the seal sticker 550, and the fraudster can read the first code information 355a. 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 in the direction from the rear side to the front side of the slot machine 1 rather than the sealing seal 550 ("front". Direction: It is arranged on the front side (negative side in the y-axis direction) in the negative direction of the y-axis). Further, when the board 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 sealing sticker 550. From the rear side to the front side of the slot machine 1 ("front" direction: negative direction on the y-axis) from the second code information 550a, the second character information 550b, etc., to the front side (negative side in the y-axis direction). Be placed.

By differentiating the positions of the slot machine 1 in the front-rear direction between the first code information 355a of the recording paper 350 and the second code information 550a of the seal sticker 550, the fraudster can use the first code information 355a and the second code information. It takes time to adjust the focus of the reader when reading the 550a, and after the fraudster reads the first code information 355a of the recording paper 350 whose code information content and character information content are substantially the same, those It is possible not to give time to read the second code information 550a of the sealing seal 550 whose contents are substantially different. In particular, by placing the sealing sticker 550 on the side where the content of the code information and the content of the character information are not substantially the same on the rear side (positive side in the y-axis direction) of the recording paper 350, the code can be given to the fraudster. Read the first code information 355a of the recording paper 350 having substantially the same information content and the character information content before the second code information 550a of the sealing sticker 550 having substantially different contents. Can be motivated.

Code information such as a one-dimensional code and a two-dimensional code such as a QR code (registered trademark) (hereinafter, appropriately referred to as "board surface code information") 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 (facing the mounting surface 63a of the component surfaces) of the component (main CPU 61, IC chip, etc.) mounted on the mounting surface 63a are opposed to each other. There is code information placed on the surface on the opposite side of the surface. In this case, in a state where the board 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 (“front” direction: negative direction of y-axis)). The board surface code information is arranged on the front side (negative side in the y-axis direction) of the seal seal 550 from the second code information 550a, and the first code information 355a of the recording paper 350 is more than the substrate surface code information. May be arranged on the front side (negative side in the y-axis direction).

The distance between the gate mark 80ag of the cover member 80a and the gate mark 80bg of the base member 80b is that the distance between the first code information 355a and the gate mark 80ag is the distance between the first code information 355a and the gate mark 80ag in the substrate case 80 of the base member 80. It is formed so as to be larger than the distance between the portion overlapping with the first code information 355a in the front view and the gate mark 80 bg. Thereby, it is possible to prevent the gate mark 80ag from interfering with the reading of the first code information 355a. Further, since the gate mark 80ag does not interfere with the reading of the first code information 355a, the fraudster is given the first code information 355a of the recording paper 350 whose code information content and character information content are substantially the same. Can be motivated to read. It should be noted that the gate marks 80ag of the cover member 80a may be provided in a larger number than the gate marks 80bg of the base member 80b to maintain more uniformity in injection molding.

In the front view of the substrate case 80, a part of the sealing seal 550 has irregularities between 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. It is attached to the surface 80a4a of the fitting portion 80a4 and the surface 80b9a1 of the first fitting forming portion 80b9a of the fitting portion 80b9 so as to come to the boundary portion where the breaking portion 80a4h is located. In the present embodiment, the boundary portion has irregularities, but the present embodiment is not limited to this. A specific example of attaching the seal seal 550 will be described with reference to FIGS. 20 (a) and 20 (b).

In the specific example of FIG. 20A, in the front view of the substrate case 80, a part of the second code information 550a is the fitting portion 80a4 of the cover member 80a and the fitting portion of the base member 80. The surface 80a4a of the fitting portion 80a4 and the mated portion 80b9 are located at the uneven boundary portion 80ab1 with the first mated forming portion 80b9a of the 80b9 and the second character information 550b is not located at the boundary portion 80ab1. It is attached to the surface 80b9a1 of the first fitting forming portion 80b9a. At this time, the broken portion 80a4h breaks the second code information 550a when the cover member 80a and the base member 80b are separated, but the second character information 550b is not broken. In this way, by locating a part of the second code information 550a at the uneven boundary portion 80ab1, the fraudster is given the impression that the second code information 550a is difficult to read, and the contents and characters of the code information are given. It is possible to motivate the reading of the first code information 355a of the recording paper 350 having substantially the same information content. Further, the second character information 550b is not located at the boundary portion 80ab1 so that the second character information 550b is not broken, so that the second character information 550b is replaced with a forged seal after being illegally opened. But it is easy to find. Further, by breaking the second code information 550a to make it unreadable and making it impossible to confirm the relationship with the second character information 550b, it is possible to create an erroneous imitation product. In addition, the second code information 550a can be reliably broken by the broken portion 80a4h. The arrangement example shown in FIG. 20A can be applied even when there is no broken portion 80a4h.

Further, the substrate case 80 may be provided with a structure (broken portion) so that such traces are easily formed. For example, by providing a cavity between the flange of the base member 80b and the flange of the cover member 80a to which the seal seal 550 does not stick, even if the seal seal 550 is to be broken with a knife or the like, the seal seal 550 bends and tears cleanly. You may not have it. Further, the substrate case 80 is provided with a seal seal cover member that covers a portion to which the seal seal 550 is attached so that the seal seal 550 cannot be broken unless the seal seal cover member is slid and removed. A protrusion that damages the seal seal 550 when the seal seal cover member is slid and removed may be provided on the inside of the cover member and on the side in contact with the seal seal. With this configuration, it is possible for a person who intends to commit fraud to leave a trace no matter how cleanly he or she tries to break the seal 550 so as not to leave a trace.

In the specific example of FIG. 20B, when the sealing seal 550 is viewed from the front of the substrate case 80, both the second code information 550a and the second character information 550b are covered with the fitting portion 80a4 of the cover member 80a and the base member 80. The surface 80a4a and the base of the fitting portion 80a4 so that the fitting portion 80b9 is not located at the uneven boundary portion 80ab1 with the first fitting forming portion 80b9a and a part of the other portion is located at the boundary 80ab1. It is attached to the surface 80b9a1 of the first fitted forming portion 80b9a of the fitted portion 80b9 of the member 80. At this time, the broken portion 80a4h is in a position where neither the second code information 550a nor the second character information 550b is broken when the cover member 80a and the base member 80b are separated, and the other portion is broken. As a result, both the second code information 550a and the second character information 550b of the seal seal 550 are not deformed such as unevenness, and the seal information 550 is not uncomfortable to the fraudster. It is possible not to give the motivation to read the second code information 550a of the seal seal 550 whose character information content is not substantially the same. In addition, when the board case 80 is opened by a legitimate worker (hole side / manufacturer side) for no illegal purpose, the second code information 550a and the second character information 550b are not broken and are reused. Even so, the functions of the second code information 550a and the second character information 550b can be maintained. The arrangement example shown in FIG. 20B can be applied even when there is no broken portion 80a4h.

Therefore, according to the above-described embodiment, the content of the first character information 354a displayed on one of the recording sheets 350 and the content of the identifiable information obtained from the first code information 355a are substantially the same. By making the content of the second character information 550b displayed on the other seal 550 different from the content of the information obtained from the second code information 550a, when one of the first code information 355a is read, the first code information 355a is read. 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 convince a person who intends to commit fraud to create a counterfeit board case 80 having an incorrect sealing seal 550 on the surface 80M by assuming 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 activities related to the substrate case 80 having the recording paper 350 and the sealing sticker 550 on the surface 80M.

In addition, when the clerk inspects, it is complicated to confirm whether the character strings such as 9 digits and 8 digits match the list, but the contents and the first character information 354a displayed on the recording paper 350 are the first. 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 seal 550 and the content of the information obtained from the second code information 550a are obtained. The imitation board case can be easily found by a simple confirmation method of confirming whether they are different. As a result, it is possible to effectively prevent fraudulent activities related to the substrate case 80 having the recording paper 350 and the sealing sticker 550 on the surface 80M.

Further, the first code information 355a, which can obtain information that can identify the first character information 354a, is arranged closer to the center of the board case 80 than the second code information 550a, which can obtain information different from the second character information 550b. Therefore, the first code information 355a can be made easier to read by the reader than the second code information 550a for a fraudulent person who tries to create a counterfeit product of the board case 80. As a result, the fraudster reads the first code information 355a first, and the content of the first character information 354a and the content of the identifiable information obtained from the read first code information 355a are substantially the same. By recognizing the existence, it is possible to induce the assumption 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.

Further, 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. Therefore, since the first code information 355a is more noticeable than the second code information 550a, it is possible to motivate the fraudster to read the first code information 355a before the second code information 550a. Further, since the first code information 355a of the recording paper 350 has a higher occupancy rate than the second code information 550a of the seal seal 550, similarly, the fraudster reads the first code information 355a before the second code information 550a. Can be motivated. Further, since the first character information 354a of the recording paper 350 is larger in size than the second character information 550b of the seal seal 550, similarly, the fraudster is asked to precede 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 character information 354a. Further, since the first character information 354a of the recording paper 350 has a higher occupancy rate than the second character information 550b of the seal seal 550, similarly, the fraudster is asked to precede 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. Further, (1) the first code information 355a of the recording paper 350 is larger in size than the second code information 550a of the seal sticker 550, and (2) the first code information 355a of the recording paper 350 is the second code information of the seal sticker 550. The occupancy rate is higher than 550a, (3) the first character information 354a of the recording paper 350 is larger than the second character information 550b of the sealing sticker 550, and (4) the first character information 354a of the recording paper 350 is the sealing sticker 550. The more the occupancy rate is higher than that of the second character information 550b, the more motivated the fraudster to read the first code information 355a before the second code information 550a.

Also, arrange the recording paper 350 whose code information content and character information content are substantially the same so as to face each other, and do not face the sealing sticker 550 which seals the one whose information is not substantially the same. By arranging the arrangement, the first code information 354a of the recording paper 350 can be made easier to read than the second code information 355a of the sealing sticker 550. Therefore, it is possible to motivate the fraudster to read the first code information 354a before the second code information 355a.

Further, the content of the third character information 750b displayed on one of the certificate stamps 750 and the content of the identifiable information obtained from the third code information 750a are substantially the same, and are displayed on the other seal seal 550. 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 one of the third code information 750a is read, it is read as the content of the first character information 750b. It is recognized that the content of the identifiable information obtained from the third code information 750a is substantially the same. Therefore, the content of the other second character information 550b and the content of the information obtained from the second code information 550a are assumed to be substantially the same, and a person who intends to commit fraudulent acts is erroneously sealed on the surface 80M. A counterfeit substrate case 80 with 550 can be created. As a result, it is possible to effectively prevent fraudulent activities related to the substrate case 80 having the sealing seal 550 on the surface 80M.

In addition, when the clerk inspects, it is complicated to confirm whether the character strings such as 9 digits and 8 digits match the list, but the contents of the third character information 750b and the third character displayed on the certificate stamp 750. 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 seal 550 and the content of the information obtained from the second code information 550a are different. The imitation board case can be easily found by a simple confirmation method of confirming whether or not the product is used. As a result, it is possible to effectively prevent fraudulent activities related to the substrate case 80 having the sealing seal 550 on the surface 80M.

Further, the third code information 750a for obtaining information that can identify the third character information 750b is arranged outside the housing 3 of the slot machine 1, and the second code information 550a for obtaining information different from the second character information 550b is provided. By arranging it in the housing 3, it is possible to make the third code information 750a easier to read by the reader than the second code information 550a for a fraudster who tries to create a copy of the board case 80. can. As a result, the fraudster reads the third code information 750a first, and the content of the first character information 354a and the content of the identifiable information obtained from the read first code information 355a are substantially the same. By recognizing the existence, it is possible to induce the assumption 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.

Further, the third code information 750a of the certificate stamp 750 is larger in size than the second code information 550a of the seal seal 550. Therefore, since the third code information 750a is more noticeable than the second code information 550a, it is possible to motivate the fraudster to read the third code information 750a before the second code information 550a. Further, since the third code information 750a of the certificate stamp 750 has a higher occupancy rate than the second code information 550a of the seal seal 550, similarly, the fraudster is requested to read the third code information 750a before the second code information 550a. Can be motivated. Further, since the third character information 750b of the certificate stamp 750 is larger in size than the second character information 550b of the seal seal 550, similarly, the fraudster is given the second code information 550b paired with the second character information 550b before the second code information 550a. It can be motivated to read the three-character information 750b and the paired third code information 550a. Further, since the third character information 750b of the certificate stamp 750 has a higher occupancy rate than the second character information 550b of the seal seal 550, similarly, the fraudster is asked to precede the second code information 550a paired with the second character information 550b. It can be motivated to read the third code information 750a paired with the third character information 750b. Further, (1) the third code information 750b of the certificate stamp 750 is larger than the second code information 550a of the seal seal 550, and (2) the third code information 750b of the certificate stamp 750 is from the second code information 550a of the seal seal 550. The occupancy rate is high, (3) the third character information 750b of the certificate stamp 750 is larger than the second character information 550b of the seal seal 550, and (4) the third character information 750b of the certificate stamp 750 is the second character of the seal seal 550. The more the occupancy rate is higher than the information 550b, the more motivated the fraudster to read the third code information 750a before the second code information 550a.

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

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

The LEDs (such as the monitor LED 32 and the LED of the ratio indicator 69) mounted on the mounting surface of the main control board 63 are the first of the recording paper 350 rather than the second code information 355a of the sealing sticker 550 in the front view of the board case 80. Even if it is arranged closer to the 1-code information 355a (in the front view of the substrate case 80, the distance between the LED and the 1st code information 355a is smaller than the distance between the LED and the 2nd code information 550a). good. As a result, the consciousness of the fraudster is directed toward the recording paper 350, so that the fraudster is given the first code information 355a of the recording paper 350 whose code information content and character information content are substantially the same. Can be motivated to read. In this case, it is preferable that the LED is not arranged in a predetermined area near the first code information 355a of the recording paper 350. For example, the predetermined area in which the LED is not arranged is set to, for example, an area in which the LED interferes with the reading of the first code information 355a to some extent under a predetermined situation. It may be a region 34a that overlaps with 355a (see FIG. 22A), and is a region 34b that is a combination of a region 34a that overlaps with the first code information 355a and a region 34b1 from the region 34a to the outside of one LED. Often (see FIG. 22B), the area 34c is a combination of the area 34a overlapping the first code information 355a and the area 34c1 from the area 355a to the outside of one two-dimensional code constituting the first code information 355a. (See FIG. 22 (c)). This makes it possible to prevent the LED from excessively interfering with the reading of the first code information 355a of the recording paper 350 by a legitimate worker.

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 (facing the mounting surface 63a of the component surfaces) of the component (main CPU 61, IC chip, etc.) mounted on the mounting surface 63a are opposed to each other. There is code information placed on the surface on the opposite side of the surface. In this case, the substrate surface code information may not be arranged in a predetermined area near the first code information 355a of the recording paper 350. For example, the predetermined area where the substrate surface code information is not arranged is set to, for example, an area where the LED interferes with the reading of the first code information 355a to some extent under a predetermined situation, and for example, the following (1) to (3). May be. (1) is a region that overlaps with the first code information 355a in the front view of the substrate case 80. (2) is an area in which the area overlapping the first code information 355a and the area from the area to the outside of half the two-dimensional codes constituting the first code information 355a are combined in the front view of the substrate case 80. .. (3) is an area in which the area overlapping the first code information 355a and the area from the area to the outside of one two-dimensional code constituting the first code information 355a are combined in the front view of the substrate case 80. .. As a result, a regular worker can smoothly read the first code information 355a of the recording paper 350 without being disturbed by the board surface code information.

Further, the substrate surface code information may be present in a predetermined area near the second code information 550 of the seal seal 550. For example, the area where the board surface code information exists is set to, for example, an area where the LED interferes with reading the second code information 550a to some extent under a predetermined situation. For example, in the front view of the board case 80, the second code The area may be an area from the outside of half of the two-dimensional codes constituting the second code information 550a of the region overlapping with the information 550a to the outside of one of the two-dimensional codes. This makes it difficult for the fraudster to read the second code information 550a by disturbing the reading of the second code information 550a by the board surface code information.

Further, in the front view of the substrate case 80, the distance between the first code information 355a of the recording paper 350 and the substrate surface code information closest to the first code information 355a is the first code information 355a of the recording paper 350 and the sealing sticker. It may be smaller than the distance of the second code information 550a of the 550. Even if a fraudster tries to read other code information after reading the first code information 355a of the recording paper 350, it is a fraudulent act to read the board surface code information that can be read without any problem. The person can be guided, thereby delaying the reading of the second code information 550a of the sealing seal 550.

Further, in the 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 board surface code information may be present between the two. As a result, after the fraudster has read the first code information 355a of the recording paper 350, the fraudster can be guided to read the board surface code information, and the second code information of the seal seal 550 can be read. It is possible to delay reaching the reading of 550a. The fact that the substrate surface code information exists on the straight line connecting the first code information 355a and the second code information 550a means that, for example, when the substrate case 80 is viewed from a certain direction, the first code information 355a and the substrate surface It suffices that at least a part of the code information and the second code information 550a are duplicated at the same time.

Further, the tallest component among the components mounted on the mounting surface 63a of the main control board 63 (from the mounting surface 63a to the top surface of the component (the surface of the surface opposite to the surface facing the mounting surface 63a). The component) having the maximum distance to) may not be arranged in a predetermined area near the first code information 355a of the recording paper 350. The tallest component is, for example, an aluminum capacitor 91a or a regulator 91b (see FIG. 6). For example, a predetermined area in which the tallest component is not arranged is set to, for example, an area in which the tallest component interferes with reading the first code information 355a to some extent under a predetermined situation. ) To (2). (1) is a region from the region overlapping the second colored portion 353 on which the first code information 355a is displayed to the region outside half of the two-dimensional codes constituting the first code information 355a in the front view of the substrate case 80. be. (2) is a region from the region overlapping the second colored portion 353 on which the first code information 355a is displayed to the region outside one two-dimensional code constituting the first code information 355a in the front view of the substrate case 80. be. As a result, it is possible to prevent the tallest part from interfering with the reading of the first code information 355a of the recording paper 350, and to smoothly read the first code information 355a of a regular worker. Become.

Further, the tallest component may be arranged so as to be entirely contained within an area overlapping the second colored portion 353 on which the first code information 355a is displayed in the front view of the substrate case 80. .. As a result, even if the tallest part is in the vicinity of the first code information 355a of the recording paper 350, the tallest part interferes with reading the first code information 355a of the recording paper 350. This can be prevented and the first code information 355a of a legitimate worker can be smoothly read.

Further, the substrate case 80 is arranged on the front side in the front view of the substrate case 80 between 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. For example, it may have a substantially box shape as shown in FIG. 23 and may include a sealing seal cover portion 900 having an opening on the rear side. In that case, in the front view of the substrate case 80, the front side of the seal seal 550 is covered with the seal seal cover portion 900, and the seal seal cover portion 900 can read the second code information 550a with a reader, and the second character information. The 550b may have transparency enough to allow a person such as an operator to discriminate characters. In this case, the recording paper 350 (first code information 355a, first character information 354a) is arranged so as to be exposed to the outside of the substrate case 80, while the sealing seal 550 (second code information 550a, second character information). 550b) is arranged so that the sealing seal cover portion 900 covers the front side of the substrate case 80 in the front view. The structure of the seal seal cover portion 900 is an example, and any structure may be used as long as it can cover the front side of the seal seal 550 when viewed from the front of the substrate case 80. As a result, by covering the front side of the second code information 550a of the seal seal 550 on which the content of the code information and the content of the character information are not substantially the same, it becomes difficult to read the second code information 550a, which is illegal. It is possible to prevent the actor from discovering that the content of the second code information 550a and the content of the second character information 550b of the seal seal 550 are not substantially the same. Similar to the cover member 80a and the base member 80b, the sealing seal cover portion 900 is made of, for example, a transparent resin (for example, a transparent ABS resin (acrylonitrile, butadiene, styrene) or the like. (Styrene or transparent polycarbonate) may be used. Further, 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. Then, in this way, the second code information 550a can be made difficult to read. As a method of lowering the transparency, a resin material having a relatively low transparency is selected. For example, the cover member 80a or the base. When the member 80b is a PC, ABS resin, which is generally considered to have lower transparency than the PC, may be used for the sealing seal cover portion 900. Further, a transparent resin material is mixed with a pigment to increase the transparency. It may be lowered and used for the seal seal cover portion 900. Further, rough surface processing such as providing fine irregularities on the injection molding mold used for forming the seal seal cover portion 900 may be performed in the second code information 550a. The seal cover portion 900 may be formed by using the injection molding mold subjected to the rough surface processing in the region overlapping with the second code information 550a. Further, the gate may be formed in the region overlapping the region overlapping with the second code information 550a. The seal seal cover portion 900 may be made so that marks, extrusion pins, and other marks that inevitably remain during molding may be formed.

Further, as shown in FIG. 23, the seal seal cover portion 900 is three-dimensional in a region near the second code information 550a of the seal seal 550 and not overlapping with the second code information 550a in the front view of the substrate case 80. The structure 900a (for example, a rib extending in the front-rear direction) may be provided. In this case, the three-dimensional structure 900a can interfere with the reading of the second code information 550a, and the fraudster can reduce the motivation to read the second code information 550a.

Further, the sealing seal 550 is continuous from the first surface portion of the flat surface of the surface 80M of the substrate case 80 and the flat surface of the entire surface (surface 80M, side surface, etc.) of the substrate case 80 and is the same as the flat surface. It is attached to the substrate case 80 so that the second code information 550a is located on the first surface portion across a plurality of surfaces including at least the second surface portion of a surface that is not on a flat surface (regardless of shape such as flat surface or curved surface). It may be done. At this time, the second character information 550b may also be arranged on the first surface portion. For example, as shown in FIGS. 24A and 24B, a substrate case in which the sealing seal 550 is continuous with the first surface portion of the flat surface of the surface 80M of the substrate case 80 and is not on the same plane as the flat portion. The second code information 550a and the second character information 550b may be arranged on the first surface portion of the flat surface of the surface 80M of the substrate case 80 so as to straddle the second surface portion of the left side surface of the 80. In the case of FIG. 24, the entire sealing seal 550 is not attached to the surface 80M of the substrate case 80. Note that FIG. 24A is a front view of the substrate case 80, and FIG. 24B is a left side view of the substrate case 80. As a result, the motivation to read the second code information 550a, etc. of the seal seal 550 of the fraudster is diminished, and the reading work of the second code information 550a, etc. of the seal seal 550 by a legitimate worker is not hindered. Can be done.

Further, the mounting component mounted on the mounting surface 63a of the main control board 63 may be an SMD (surface mount device). 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 double-sided mounting component 99A is mounted on both sides due to the shape of the terminal 99A1. A gap YY is formed between the component 99A and the mounting surface 63a (see FIG. 26A). On the other hand, when the 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, the SMD 99B and the mounting surface 63a are different depending on the shape of the terminal 99B1 of the SMD 99B. There is almost no gap between the two (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 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 first code information 355a of the recording paper 350 and the top surface of the SMD99B (the surface of the surface of the mounting component opposite to the surface facing the mounting surface 63a) of the mounting surface 63a. The distance ZZ in the vertical direction is larger, and it is possible to prevent the SMD99B from interfering with the reading of the first code information 355a of the recording paper 350.

Further, as shown in FIG. 2, when the board case 80 is installed above the inside of the housing 3 of the slot machine 1, the sealing seal 550 covers the board case 80 as shown in FIG. 25 when viewed from the front. It may be arranged on the upper surface side of the housing 3 in the surface 80M of the substrate case 80 from the recording paper 350 so as to straddle the boundary between the member 80a and the base member 80b. Here, the upper part of the housing 3 is shaded by the top plate or the like of the housing 3 and becomes dark. Therefore, the sealing sticker 550 whose code information content and character information content are not substantially the same is arranged at a darker position in the housing 3 than the recording paper 350 whose contents are substantially the same. Therefore, the fraudster 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 so as to be closer to the "B caulking portion" than the sealing sticker 550, but the present invention is not limited to this, and the sealing sticker is not limited to this. The 550 side may be arranged so as to be closer to the "B caulking portion".

Further, in a state where the surface 80M of the substrate case 80 is provided with a portion indicating the attachment position of the recording paper 350, for example, portions having a predetermined shape are provided at the four corners of the attachment position of the recording paper 350 and the substrate case 80 is attached to the slot machine 1. , The portion may be arranged on the opposite side of the hinge mechanism 4 with respect to the seal seal 550 (in the order of the hinge mechanism 4, the seal seal 550, and the portions).

Further, the sealing sticker 550 is more easily deteriorated (yellowing and peeling) than the recording paper 350, and the sealing sticker 550 is more easily deteriorated than the recording paper 350 by the vent 3h provided on the back plate 3a of the housing 3 (FIG. 2). (See) It may be arranged closer (the distance between the sealing sticker 550 and the vent 3h is smaller than the distance between the recording paper 350 and the vent 3h). As an example, paper is given as the material of the sealing sticker 550.

Further, the connector arranged on the main control board 80 housed in the board case 80 may be present around the sealing sticker, not around the recording paper 350. Further, when the board case 80 is attached to the housing 3 of the slot machine 1, when the board case 80 is viewed from the front, at least the sealing seal 550 is placed on the mounting surface 63a of the main control board 63. A connector may be provided on the upper portion, and the connector may not be provided on at least the upper portion of the recording paper 350 around 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, is provided to the fraudster rather than the second code information 550a of the sealing sticker 550 in which the wiring cable connected to the connector interferes with reading. Can motivate you 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 more than the sealing sticker 550, and the first code information of the recording paper 350. The direction in which 355a, the first character information 354a, etc. are from the rear side to the front side of the slot machine 1 ("front" direction: y-axis) than the second code information 550a, the second character information 550b, etc. of the seal seal 550. It is said that it is arranged on the front side (negative side in the y-axis direction) in the negative direction of), but it is not limited to this, and the positional relationship between the recording paper 350 and the sealing sticker 550 and the first of the recording paper 350. 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. of the seal seal 550 is the direction from the rear side to the front side of the slot machine 1 (the "front" direction). : In the negative direction of the y-axis), the opposite may be true.

Further, 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 to the first code information 355a of the recording paper 350 in the front view of the substrate case 80. (In the front view of the substrate case 80, 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). As a result, the LED can interfere with the reading of the second code information 550a of the seal seal 550 by the fraudster. 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 seal 550. For example, the predetermined area in which the LED is not arranged is set to, for example, an area in which the LED excessively interferes with the reading of the second code information 550a under a predetermined situation, and is, for example, the following (1) to (3). You may. (1) is a region that overlaps with the second code information 550a in the front view of the substrate case 80. (2) is a region in which the region overlapping with the second code information 550a and the region from the region to the outside of one LED are combined in the front view of the substrate case 80. (3) is an area in which the area overlapping the second code information 550a and the area from the area to the outside of one two-dimensional code constituting the second code information 550a are combined in the front view of the substrate case 80. .. This makes it possible to prevent the LED from excessively interfering with the reading of the second code information 550a of the sealing seal 550 by a legitimate worker.

Further, the contents of the above-described embodiment and the above-described modification include a board case for accommodating a control board other than the main control board 63 (for example, a sub-control board 73 attached to the inner wall surface on the left side of the housing 3: see FIG. 2). Can also be applied by making appropriate changes.

Further, the contents of the above-described embodiment and the above-mentioned modification can be appropriately combined.

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

Summarizing the contents including the above-described embodiment and the above-mentioned modification, the following contents are appropriately combined.

In this way, the first code information becomes more prominent than the second code information, and it is possible to motivate the fraudster to read the first code information rather than the second code information. Further, in this way, a fraudster who knows that the first code information and the first character information have substantially the same contents can substantially obtain the second code information and the second character information. It can be induced to think that the contents are the same, and the motivation to bother to read the small and difficult-to-read second code information can be diminished.

(22) The gaming machine has a front opening, includes a housing formed in a substantially square box shape, and a front door that can open and close the front opening by using a hinge mechanism. 2 The display unit may be formed on the hinge mechanism side. In this way, the first display unit in which the content of the code information and the content of the character information are substantially the same when the front door is opened is compared with the second display unit in which the contents are not substantially the same. By making it noticeable first, it is possible to make it easier for the fraudster to read the first code information of the first display unit and make it harder to read the second code information of the second display unit. ..

(23) The direction of the code constituting the first code information of the first display unit is the direction from the upper side to the lower side when the board case is viewed from the front side (when viewed from the front of the board case) (vertical direction). ) May be used.

(24) When the gaming machine is viewed from the front side of the gaming machine (in front view of the gaming machine), the direction of the code constituting the third code information of the third display unit is the direction from the upper side to the lower side. (Portrait) may be used.

(25) When the direction of the code constituting the second code information of the second display unit is viewed from the front side of the board case (when viewed from the front of the board case), the direction other than the direction from the upper side to the lower side, for example, the left side. The direction may be from the right side (horizontal direction) or from the lower side to the upper side (vertical direction rotated by 180 °).

In the case of (23) and (25), the first code information of the first display unit, which has 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 of the second display unit, which is not the same, does not face each other, the first code information is easier to read than the second code information 355a, and the fraudster is notified before 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, which has 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 of the second display part, which is not the same, does not face each other, the third code information is easier to read than the second code information, and the fraudster is given the second code information before the second code information. 3 Can be motivated to read code information.

(26) The direction of the characters constituting the first character information of the first display unit is the direction from the upper side to the lower side when the board case is viewed from the front side (when viewed from the front of the board case) (vertical direction). ) May be used.

(27) When the gaming machine is viewed from the front side of the gaming machine (in front view of the gaming machine), the direction of the characters constituting the third character information of the third display unit is the direction from the upper side to the lower side. It may be (portrait).

(28) When the direction of the characters constituting the second character information of the second display unit is viewed from the front side of the board case (when viewed from the front of the board case), the direction other than the direction from the upper side to the lower side, for example, the left side. The direction may be from the right side (horizontal direction) or from the lower side to the upper side (vertical direction rotated by 180 °).

In the case of (26) and (28), the first character information of the first display unit whose code information content and character information content are substantially the same for a person faces each other, and the information is substantially the same. Since the second character information of the second display part that is not exactly the same does not face each other, the first character information is easier to read than the second character information, and the fraudster is paired with the second character information. 2 It is possible to motivate to read the first code information paired with the first character information before the code information.

In the case of (27) and (28), the third character information of the third display unit, which has 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 of the second display part that is not exactly the same does not face each other, the third character information is easier to read than the second character information, and the fraudster is paired with the second character information. It can be motivated to read the third code information paired with the third character information before the second code information.

(29) The second display unit is positioned so that the second code information includes a portion of the boundary between the cover member and the base member that is not on the same plane, and the second character information is the cover member and the base member. It is displayed so that it is located outside the boundary of. In this way, the second code information is deformed, giving the fraudster the impression that it is difficult to read the second code information, and the first code information and the character information are substantially the same. It is possible to motivate the first code information of the display unit to be read before the second code information of the second display unit whose contents are not substantially the same. Further, by preventing the second character information from being broken, even if a forged second display unit is displayed after the cover member and the base member are illegally separated, it can be easily found.

(30) In the second display unit, neither the first code information nor the second character information of the second display unit is located at the boundary portion between the base member and the cover member, and other portions are located at the boundary portion. Is displayed. By doing so, both the second code information and the second character information of the second display unit are not deformed, and the content of the code information can be obtained by not giving a sense of discomfort to the second display unit to the fraudster. It is possible not to give the motivation to read the second code information of the second display unit which is not substantially the same in the content of the character information. Further, when a legitimate worker separates the cover member and the base member of the board case for no improper purpose, the second code information and the second character information are not broken and are reused. Also, the functions of the second code information and the second character information can be maintained.

(31) The substrate case may include a broken portion in which the second code information is broken when the cover member and the base member are separated, but the second character information is not broken. In this way, the second code information can be reliably broken by the broken portion, making it impossible to read the second code information, and the fraudster has an erroneous relationship with the second code information and the second character. You end up making a copy of the second display where the information is displayed.

(32) In a state where the board case is attached to the back plate of the housing of the gaming machine and housed inside the gaming machine, the first display unit (first code information, first character information) and the second display unit (Second code information, second character information) may be at different positions in the direction from the rear side to the front side of the gaming machine. By doing so, it takes time to adjust the focus of the reader when reading the first code information and the second code information, and the fraudster is the one whose code information content and character information content are substantially the same. After reading the first code information of one display unit, it is possible not to give a time margin for reading the second code information of the second display unit whose contents are substantially different from each other.

(33) In (32) above, the first display unit (first code information, first character information) is behind the gaming machine than the second display unit (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 fraudster is presented with the first code information of the first display unit, which has substantially the same content of the code information and the content of the character information, and the second display of the person whose contents are substantially different. It can be motivated to read before the second code information of the part.

(34) In (33) above, the fourth code information exists on the surface of the circuit board facing the first display unit, and the fourth code information is present in the direction from the rear side to the front side of the gaming machine. It may be assumed that the code information is on the front side of the second code information of the second display unit, and the first code information of the first display unit is 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 easily read in this order, which motivates the user to read the first code information and makes it difficult to read the second code information.

(35) The first display unit is formed of a transparent seal, the second display unit is formed of an opaque seal, and each corner of the outer periphery of the first display unit is R-chamfered to form the second display unit. Each corner of the outer circumference is R-chamfered, and the R value of the R-chamfer of the first display unit is smaller than the R value of the R-chamfer of the second display unit (for example, the R-chamfer of the first display unit is R0. .3 mm, and the R chamfer of the second display unit is R2 mm). In the case of a transparent sticker, fingerprints etc. attached during the pasting work will be confused with traces of fraud (traces of fraud such as peeling off the transparent sticker and making a hole in the board case and sticking the transparent sticker again). .. The smaller the R, the smaller the contact area of the finger, etc., which not only reduces the adhesive strength but also prevents the adhesion of fingerprints, foreign matter attached to the finger, etc., so that the first display unit formed of a transparent sticker In that case, it is desirable that R is small. On the other hand, if R is large, the work efficiency of the pasting work is improved, so that the second display portion formed of the opaque sticker does not have the above-mentioned adverse effects due to the above-mentioned adhesion of fingerprints or the like, so workability should be prioritized. desirable. Further, a slit may be provided in the second display unit, and in this case, it is desirable to give priority to workability.

(36) When the board case is viewed from the front side (when viewed from the front of the board case) in a state where the board case is housed inside the housing of the gaming machine, the first code information and the second display of the first display unit are displayed. The second code information of the unit may not be aligned in the vertical direction or the horizontal direction. In this way, it becomes difficult for the fraudster to continuously read the first code information of the first display unit and the second code information of the second display unit, and the fraudster has the first code information and the second code information. It is possible to eliminate the time margin for reading both code information.

(37) The first gate mark of the cover member and the second gate mark of the base member are the first code information and the first gate mark when the substrate case is viewed from the front side (when viewed from the front of the substrate case). The distance may be formed so as to be larger than the distance between the portion of the base member that overlaps with the first code information in the front view of the substrate case and the second gate mark. In this way, it is possible to prevent the first gate mark from interfering with the reading of the first code information. In addition, since the first gate mark does not interfere with the reading of the first code information, the fraudster is given the first code information of the first display unit having substantially the same content of the code information and the content of the character information. Can be motivated to read.

(38) When the board case is viewed from the front side of the board case (when viewed from the front of the board case), the second code information arranged on the front side of the second display unit can be read by a reader. By providing a cover portion having a transparency such that the characters of the second character information can be discriminated by a person, the front side of the second display portion is covered with the cover portion in the front view of the substrate case, while the first display is provided. The portion may be exposed to the outside of the substrate case. By doing so, it is possible to give the fraudster an impression that the exposed first code information is easier to read than the second code information whose front side is covered with the cover portion, and it is possible to give the fraudster an impression that it is easier to read than the second code information. It can be motivated to read the first code information. In addition, it becomes difficult to read the second code information of the second display unit where the content of the code information and the content of the character information are not substantially the same, and the fraudster can read the content of the second code information and the second character. It can prevent the discovery that the content of the information is not substantially the same.

(39) In (38) above, the cover portion is a region that is in the vicinity of the second code information and does not overlap with the second code information when the board case is viewed from the front surface side (when viewed from the front of the board case). May be provided with a three-dimensional structure. In this way, the three-dimensional structure can interfere with the reading of the second code information, and the fraudster can reduce the motivation to read the second code information.

(40) The second display unit is a first surface portion of a flat surface of the surface of the substrate case and a surface of the entire surface of the substrate case 80 that is continuous with the flat surface and is not on the same plane as the flat surface. It may be displayed on the substrate case so that the second code information is located on the first surface portion across a plurality of surfaces including at least the two surface portions. In this case, a part of the second display unit may be arranged on a surface other than the surface of the substrate case. In this way, the motivation for reading the second code information, etc. of the second display unit of the fraudster is diminished, and the reading work of the second code information, etc. of the second display unit by a legitimate worker is not hindered. can do.

(41) When the board case is installed above the inside of the gaming machine housing and the board case is installed above the inside of the gaming machine housing, the second display unit is more substrate than the first display unit. It may be displayed on the upper surface side of the housing among the surfaces of the case. In this way, the second display unit in which the content of the code information and the content of the character information are not substantially the same is arranged at a darker position in the housing than the first display unit in which the contents are substantially the same. Therefore, it is possible to motivate the fraudster to read the first code information of the first display unit whose contents are substantially the same.

(42) A light source is mounted on the circuit board, and the distance between the light source and the first code information is the distance between the light source and the second code information when the board case is viewed from the front side (when viewed from the front of the board case). It may be arranged so as to be smaller than the distance from. By doing so, the consciousness of the fraudster is directed toward the first display unit, so that the fraudster is given the first display unit in which the content of the code information and the content of the character information are substantially the same. 1 Can be motivated to read code information.

(43) In the above (42), it is assumed that the light source is not arranged in a predetermined area near the first code information of the first display unit when the substrate case is viewed from the front surface side (when viewed from the front of the substrate case). good. In this way, it is possible to prevent the light source from excessively hindering the reading of the first code information of the first display unit by a legitimate worker.

(44) A light source is mounted on the circuit board, and the distance between the light source and the second code information is the distance between the light source and the first code information when the board case is viewed from the front side (when viewed from the front of the board case). It may be arranged so as to be smaller than the distance from. In this way, the light source can interfere with the reading of the second code information of the second display unit by the fraudster.

(45) The fourth code information exists on the surface of the circuit board facing the first display unit, and the fourth code information is obtained when the board case is viewed from the front side (front view of the board case). In), it may not be arranged in a predetermined area near the first code information of the first display unit. In this way, a legitimate worker can smoothly read the first code information of the first display unit without being disturbed by the fourth code information. It can be motivated to read the code information.

(46) On the facing surface of the circuit board surface facing the first display unit, when the substrate case is viewed from the front side (when viewed from the front of the substrate case), the second code information of the second display unit is displayed. It is assumed that the fourth code information exists in a predetermined area nearby. In this way, it is possible to make it difficult for the fraudster to read the second code information by disturbing the reading of the second code information by the fourth code information, so that the fraudster can be motivated to avoid reading the second code information.

(47) The fourth code information exists on the surface of the circuit board facing the first display unit, and when the board case is viewed from the front side (when viewed from the front of the board case), the first display is displayed. The distance between the first code information of the unit and the fourth code information closest to the first code information may be smaller than the distance between the first code information of the first display unit and the second code information of the sealing seal. In this way, even if the fraudster reads the first code information of the first display unit and then tries to read other code information, there is no problem even if the fourth code information is read. It is possible to induce a cheating person to read the information, thereby delaying the reading of the second code information of the second display unit.

(48) The fourth code information exists on the surface of the circuit board facing the first display unit, and when the board case is viewed from the front side (when viewed from the front of the board case), the first display is displayed. It is assumed that the fourth code information exists between the first code information and the second code information on a straight line connecting the first code information of the unit and the second code information of the second display unit. In this way, after the fraudster has read the first code information of the first display unit, the fraudster can be guided to read the fourth code information, and the second display unit can be used. 2 It is possible to delay the reading of the code information.

(49) The mounting component mounted on the surface of the circuit board facing the first display unit may be an SMD (surface mount device). By doing so, as compared with the DIP (Dual In-line Package) component, the first code information of the first display unit and the top surface of the mounted component (the surface of the component surface opposite to the facing surface). The distance between the facing surfaces in the vertical direction can be increased, and it is possible to prevent the mounted component from interfering with the reading of the first code information of the first display unit.

(50) The first display unit is a code and a code constituting the first code information when the first display unit is viewed from a surface opposite to the surface on which the first code information and the first character information are displayed. The orientation of the characters constituting the first character information can be seen through so that a person can discriminate, but the second display unit is the second display unit from the side opposite to the side on which the second code information and the second character information are displayed. (2) When the display unit is viewed, the direction of the code constituting the second code information and the character constituting the second character information may not be transparent enough to be discernible by a person. By doing so, when the first display unit is displayed before assembling the circuit board and the board case, the vertical relationship of the first display unit is confirmed from the back when the circuit board is fixed to the cover member of the board case. The circuit board can be fixed to the cover member without making a mistake in the direction in which the circuit board is attached to the cover member.

(51) The tallest mounting component among the mounting components mounted on the facing surface facing the first display portion of the surface of the circuit board (from the facing surface to the top surface of the mounting component (opposing of the surface of the component). The mounting component) having the maximum distance to the surface facing the surface and the surface opposite to the surface) may not be arranged in a predetermined area near the first code information of the first display unit. By doing so, it is possible to prevent the tallest mounting component from interfering with the reading of the first code information of the first display unit, and to smoothly read the first code information of a legitimate worker. Will be possible.

(52) The first display unit includes a colored region for displaying the first code information, and when the substrate case is viewed from the front side (when viewed from the front of the substrate case), it is included in the surface of the circuit board. The tallest mounting component among the mounting components mounted on the facing surface facing the first display unit (from the facing surface to the top surface of the mounting component (the surface of the component surface opposite to the facing surface) The mounting component with the maximum distance to)) is such that the entire tallest mounting component fits within the area that overlaps the colored area when the board case is viewed from the front side (when viewed from the front of the board case). It may be arranged. By doing so, even if the tallest mounting component is in the vicinity of the first code information of the first display unit, the tallest mounting component can display the first code information of the first display unit. It is possible to smoothly read the first code information of a legitimate worker by preventing it from becoming an obstacle when reading.

(52) The gaming machine has a support member for attaching the board case to the housing of the gaming machine, and the second display unit is more than the first display unit and the B caulking portion that engages the support member and the board case. It may be close. As a result, the confirmation work of the B caulking portion by the clerk and the confirmation work of the forgery of the second display by the fraudster can be performed in a series of flows.

(53) The game machine has a front opening, includes a housing formed in a substantially square box shape, and a front door that can open and close the front opening by using a hinge mechanism, and the board case is the first display unit.
