[0007] (Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an entire gaming machine 1 according to an embodiment. FIG. 1(A) is a view of the gaming machine 1 as seen from the front side Y1. FIG. 1B is a perspective view of the front door 2a in an open state. 1, in the embodiment, the gaming machine 1 is an example of a medal-less reel type gaming machine (slot machine) that does not use real medals, but manages medals as electronic data (credit medals) to execute games. Note that the gaming machine 1 is not limited to this, and may be a device that uses real medals.

[0008] The gaming machine 1 has a cabinet 2 with a front door 2a that can be opened and closed. The gaming machine 1 is brought into a state in which a game can be started by betting a predetermined number of medals (for example, three medals) in response to the operation of the bet button 4. When the game is ready to start, the player operates the start lever 5 to start the game, and the drum unit 6 starts spinning the reels 8L, 8C, and 8R. When the player presses the stop buttons 7L, 7C, and 7R, the reels 8L, 8C, and 8R stop. The player is awarded medals according to the combination of symbols that stop.

[0009] The main control unit and the sub-control unit control the game of the gaming machine 1. The main control unit and the sub-control unit are equipped with CPUs and the like mounted on the main control board 11 and the sub-control board 12, respectively. The main control unit performs internal lottery processing to determine winning combinations such as minor combinations and bonuses by lottery, and processing to pay out medals according to combinations of symbols. The sub-control unit controls presentation output means such as the speaker 13, lamp 14, and display unit 15 based on control commands sent from the main control unit, and performs presentations synchronized with the game.

[0010] As shown in FIG. 1(B), the main control board 11 is housed in a board case portion 50. The board case part 50 is disposed within the housing 2 in a range between the rear side Y2 and the upper side Z2. [Configuration of the vicinity of the board case part 50] The configuration in the vicinity of the board case portion 50 will be described. In the embodiments and drawings, an XYZ Cartesian coordinate system is used as appropriate. This coordinate system corresponds to the left-right direction X (left side X1, right side X2), the front-rear direction Y (front side Y1, rear side Y2), and the vertical direction Z (lower side Z1, upper side Z2) when the gaming machine 1 is viewed from the front (see FIG. 1(A) and the like). The direction of the board case part 50 is basically described in the state where it is arranged in a fixed position (the state in FIG. 2, FIG. 3, and the like). In the drawings explaining the configuration near the board case part 50, the illustration of the cabinet 2, the back panel 2c, and the like is omitted as appropriate. The configuration in the vicinity of the board case portion 50 is substantially symmetrical. In the following description, only one of the left and right configurations will be described as appropriate, and a description of the other configuration will be omitted.

[0011] In the embodiment, "non-separable" refers to a configuration in which the part or other parts cannot be disassembled or separated from the gaming machine 1 unless one of the parts is destroyed. In other words, when disassembling or separating a part that is attached "non-separably" from other parts, one of the parts must be destroyed. For example, if non-separably connected parts are separated for the purpose of fraud or tampering, traces will remain on one of the parts. This can prevent tampering, etc. In addition, touching a component part with bare hands or a tool such as a screwdriver is also called "access."

[0012] FIG. 2 is a view of the vicinity of the board case part 50 of the embodiment as viewed from the front side Y1. FIG. 3 is a perspective view of the vicinity of the board case portion 50 of the embodiment. 4 and 5 are perspective views of the configuration in the vicinity of the board case part 50 of the embodiment, with the base part 20, the rail parts 30L and 30R, the board case part 50, the connecting members 70L and 70R, and the like separated from each other. Fig. 4 is a view seen from the front side Y1 and the upper left, and Fig. 5 is a view seen from the rear side Y2 and the upper right. 6 and 7 are perspective views of the configuration in the vicinity of the board case part 50 according to the embodiment, in which the base part 20, the board case part 50, the connecting members 70L and 70R, etc. are separated from each other. Fig. 6 is a view seen from the front side Y1 and the upper left, and Fig. 7 is a view seen from the rear side Y2 and the upper left. FIG. 8 is a perspective view (viewed from the front side Y1 and upper left) of the vicinity of the substrate case part 50 in the embodiment in a rotated state. FIG. 9 is a perspective view (viewed from the front side Y1 and upper left) of the vicinity of the substrate case part 50 in the embodiment in a state where the substrate case part 50 has been rotated and slid to the upper side Z2. FIG. 10 is a vertical cross-sectional view of the vicinity of the lock portion 17 of the embodiment. FIG. 10A is a vertical cross-sectional view of the locked state. FIG. 10B is a vertical cross-sectional view of the unlocked state. FIG. 10C is a vertical cross-sectional view illustrating a manner in which the board case part 50 rotates in the unlocked state.

[0013] As shown in FIGS. 2 to 5, the vicinity of the board case portion 50 includes, as main components, the base portion 20, two assemblies of the board case portion 50, and two connecting members 70L and 70R.

[0014] As shown in Fig. 3 etc., the board case part 50 is held so as not to move relative to the base part 20 during normal use of the gaming machine 1 (such as when the gaming machine 1 is in operation during opening hours of the store). Such an arrangement during normal use is also called a fixed position. When the board case part 50 is arranged in the fixed position, the overall external shape of the base part 20 and the board case part 50 is a rectangular parallelepiped with a small height (length in the front-rear direction Y). On the other hand, as shown in Fig. 8 and other figures, during maintenance or the like in a store, the board case part 50 is rotated in the front-rear direction Y around the axis of rotation shaft 52 parallel to the left-right direction X with respect to the base part 20. Such a rotated state is also referred to as a rotated state or a pivoted state. Also, as shown in Fig. 8 and other figures, in the rotated state, the board case part 50 is slidable in the vertical direction Z with respect to the base part 20. Such a slid state is also referred to as a sliding state.

[0015] As shown in FIG. 10(A), the gaming machine 1 includes a lock unit 17. The locking portion 17 includes a locking claw 18 and a flange portion 19 . The locking claw 18 is provided on the upper side of the board case part 50 and is slidable in the vertical direction Z. The locking claw 18 is biased toward the upper side Z2 by a biasing member 18b such as a coil spring. The flange portion 19 is provided on the upper side of the base portion 20, and the tip 18a of the locking claw 18 engages with the flange portion 19. This prevents the board case part 50 from rotating around the axis of the rotation shaft 52, and maintains the state in which it is disposed in a fixed position.

[0016] 10(B) and 10(C), when rotating or sliding the board case part 50, the operator (inspector) operates the locking claw 18 to move to the lower side Z1, and then after disengaging the tip 18a of the locking claw 18 from the flange part 19, the operator can tilt the board case part 50 to the front side Y1. When the board case part 50 has rotated to such an extent that the tip 18a of the locking claw 18 is positioned outside the recessed part 21a of the base part 20, the locking claw 18 may be returned to its original position. When returning the rotated substrate case part 50 to its fixed position, the worker can simply follow the above steps in reverse.

[0017] (Base part 20) The configuration of the base portion 20 will be described with reference to FIGS. 2 to 7, 11 to 13, etc. FIG. 11 is a diagram illustrating the vicinity of the joining member fixing portion 21g of the base portion 20 according to the embodiment (see arrow 11 in FIG. 6). FIG. 11 shows a state in which the base portion 20 is attached to the rear plate 2c, and the joining members 70L, 70R are not attached to the base portion 20. In FIG. FIG. 11(A) is a view seen from the front side Y1. FIG. 11B is a cross-sectional view taken along line BB of FIG. FIG. 11C is a cross-sectional view taken along line CC of FIG. FIG. 12 shows a state in which the base portion 20 of the embodiment is attached to the rear plate 2c, and also shows a state in which the joining members 70L and 70R are attached to the base portion 20. In FIG. FIG. 12A is a view seen from the front side Y1. FIG. 12B is a cross-sectional view taken along line BB of FIG. FIG. 12C is a cross-sectional view taken along line CC of FIG. FIG. 12D is a cross-sectional view taken along line DD of FIG. FIG. 13 is a diagram showing the rail portion 30R alone according to the embodiment. FIG. 13A is a view seen from the rear side Y2. FIG. 13B is a view seen from the left side X1. FIG. 13C is a view seen from the front side Y1. FIG. 13(D) is a view seen from the right side X2. FIG. 13(E) is a perspective view seen from the front side Y1 and the upper left. In FIG. 13, the outline of the guide groove 32 is indicated by a thick line. FIG. 14 is a diagram illustrating the configuration of the area near the window portions 35 of the rail portions 30L and 30R near the board case portion 50. As shown in FIG. 14(A) and 14(B) are views of the vicinity of the windows 35R, 35L of the rail portions 30L, 30R, respectively, as viewed from the front side Y1. FIG. 14C is a cross-sectional view taken along line CC of FIG. 14B.

[0018] 4 and 5, the base portion 20 includes a base case portion 21 (base portion) and rail portions 30L, 30R. The base case portion 21 and the rail portions 30L, 30R are separate members, that is, separate components. The base case portion 21 is a member that constitutes the main portion of the base portion 20. The base case portion 21 is a molded product made of a transparent resin material or the like, and has light-transmitting properties. The base case portion 21 is a box-shaped member that is open on the front side Y1. The base case portion 21 includes a recess 21a, mounting holes 21b and 21c, a rail mounting recess 21d, a pilot hole 21f, and a coupling member fixing portion 21g. The recess 21a is an opening that opens to the front side Y1. The recess 21a accommodates the board case part 50 in a fixed position. The mounting holes 21b and 21c are through holes for fixing the base case part 21 with screws 20a (fixing members) to the front surface (predetermined location) of the rear plate 2c of the housing 2. The mounting holes 21b are provided on the left and right sides of the range of the upper side Z2 of the bottom part (the plate part on the rear side Y2) of the recessed part 21a, and the mounting holes 21c are provided on the left and right sides of the range of the lower side Z1. As shown in FIG. 4, FIG. 11(B), etc., the base case portion 21 is fixed with screws from the front side Y1, utilizing the mounting holes 21b, 21c and the pilot holes 2d in the rear plate 2c.

[0019] The rail mounting recesses 21d and the pilot holes 21f are portions for mounting the rail portions 30L and 30R. The rail mounting recesses 21d are provided on the left and right side portions of the base case portion 21 (portions constituting the left and right side walls of the base case portion 21), respectively. The rail mounting recess 21d is a recess that opens to the rear side Y2. A part of the rail mounting recess 21d penetrates the base case portion 21 and also opens into the recess 21a (see the area within the two-dot chain line in FIG. 4). A front plate portion of the rail mounting recess 21d (a bottom portion of the rail mounting recess 21d) serves as a cover portion 21e that covers the attached rail portions 30L, 30R from the front side Y1 (see the area within the two-dot chain line in FIG. 6). The pilot holes 21f are holes for screwing the rail portions 30L and 30R. The three pilot holes 21f are arranged side by side in the vertical direction Z (see FIG. 5).

[0020] The coupling member fixing portion 21g is a portion for attaching the coupling members 70L, 70R to the base portion 20 in an inseparable manner. 2, when viewed from the front side Y1, the left and right coupling member fixing portions 21g are provided on the left side X1 and right side X2, respectively, within the range of the upper side Z2 of the base portion 20. These two coupling member fixing portions 21g are provided in a range directly above the rail portions 30L, 30R and in a range not overlapping with the board case portion 50.

[0021] As shown in FIGS. 11 and 12, the joining member fixing portion 21g has three claw engagement holes 21h, 21i, and 21j. The claw engagement holes 21h, 21i, and 21j are holes for engagement with claw portions 72h, 72i, and 72j (described later) of the coupling members 70L and 70R, respectively. The upper edge of the claw engagement hole 21h, the lower edge of the claw engagement hole 21i, and the left and right outer edges of the claw engagement hole 21j are formed into a flange shape, and the claw portions 72h, 72i, and 72j of the connecting members 70L and 70R are hooked onto them. As a result, the connecting members 70L and 70R are fixed to the base portion 20.

[0022] (Rail section 30L, 30R) The rail portions 30L and 30R have a rectangular parallelepiped shape that is elongated in the vertical direction Z. The rail parts 30L, 30R are members that rotatably and slidably support the board case part 50. The rail parts 30L, 30R are made of a non-translucent resin material that has a sliding property that can suppress catching when the board case part 50 slides. A resin material having such characteristics is preferably a material containing POM (polyacetal), and may also be a material containing PA (polyamide) or the like.

[0023] The base case 21 and the rails 30L, 30R may be integrally formed from POM. However, since POM is an expensive resin material, such an integral structure would increase the parts cost, and since POM is non-translucent, the internal structure cannot be seen from the outside. For this reason, it is preferable to make the base case 21 and the rails 30L, 30R separate components, as in the embodiment.

[0024] The rail portions 30L and 30R have a symmetrical configuration, and the main structural difference between them, as described below, is the size of the window portion 35. Here, the rail portion 30R will be mainly described, and a detailed description of the rail portion 30L will be omitted. As shown in FIG. 13, the rail portion 30R includes a mounting hole 31, a guide groove 32 (support portion, guide hole), and a window portion . The mounting holes 31 are holes penetrating in the front-rear direction Y for mounting the rail portion 30R to the base case portion 21. Three mounting holes 31 are arranged side by side in the vertical direction Z. When the rail portion 30R is arranged in the rail mounting recess 21d of the base case portion 21, the mounting holes 31 communicate with the pilot holes 21f (see the rail portion 30L in FIG. 5) of the base case portion 21. The rail portion 30R is fixed to the base case portion 21 from the rear side Y2 using the mounting holes 31 and the pilot holes 21f.

[0025] In this way, the rail portions 30L, 30R are fixed with screws while being accommodated in the rail mounting recesses 21d of the base portion 20 (see FIG. 5, etc.). In addition, since the back plate 2c is disposed on the rear side Y2 of the base portion 20, the screws for fixing the rail portions 30L, 30R are inaccessible. As a result, the rail portions 30L, 30R are assembled in the gaming machine 1 in an inseparable manner.

[0026] The guide groove 32 is a hole into which the rotating shaft 52 of the substrate case part 50 is inserted and into which the rotating shaft 52 slides. When the lock part 17 is unlocked, the guide groove 32 supports the substrate case part 50 so as to be rotatable around the axis of the rotating shaft 52. The guide groove 32 is provided so as to recess the side portion on the left side X1 (left / right inner side) of the rail portion 30R toward the right side X2 (left / right outer side). When viewed from the left-right direction X, the guide groove 32 has a shape that is elongated in the vertical direction Z. As a result, the guide groove 32 guides the rotation shaft 52 so that it can slide in the vertical direction Z.

[0027] The guide groove 32 includes an insertion hole 32a (opening), a lower guide groove 32b, an upper guide groove 32c, and an inclined groove 32d. The insertion / removal hole 32a is an opening provided at the upper end of the guide groove 32. During assembly, disassembly, etc., the rotating shaft 52 is inserted into and removed from the guide groove 32 by utilizing the insertion / removal hole 32a. The lower guide groove 32b and the upper guide groove 32c are both elongated grooves that are long in the vertical direction Z. The lower guide groove 32b constitutes the main part of the guide groove 32. The upper guide groove 32c is disposed on the front side Y1 and on the upper side Z2 of the lower guide groove 32b. The inclined groove 32d is inclined toward the upper side Z2 as it approaches the front side Y1. The inclined groove 32d connects the lower guide groove 32b and the upper guide groove 32c in a crank shape.

[0028] The window portion 35 is an opening that allows the rotation shaft 52 to be viewed from the outside. The window portion 35 is a through-hole that penetrates in the front-rear direction Y through a plate portion on the front side Y1 of the rail portion 30R. As shown in FIG. 14(B), when viewed from the front side Y1, the window portion 35 has an elongated shape, and the installation range of the window portion 35 partially overlaps with the movement range of the head portion 52b of the rotation shaft 52 of the rail portion 30R. As shown in Fig. 14(B), the length of the window portion 35R of the rail portion 30R is approximately the same as the size of the head of the rotating shaft 52. On the other hand, as shown in Fig. 14(A), the length of the window portion 35L of the rail portion 30L is sufficiently elongated in the vertical direction Z (approximately the length of the upper half of the rail portion 30L). The size of the window portions 35L, 35R of the rail portions 30L, 30R is not limited thereto, and for example, both may be the same size.

[0029] Here, the cover portion 21e of the base case portion 21 is disposed on the front side Y1 of the rail portions 30L and 30R (see FIG. 14C, etc.). This allows the cover portion 21 to protect the rotation shaft 52 so that it cannot be accessed from the outside. Since the base case part 21 is translucent, when observed from the front side Y1, the rail parts 30L, 30R can be seen through the cover part 21e. Therefore, by sliding the board case part 50 to a position where the rotating shaft 52 overlaps with the window part 35, the worker can see the head part 52b of the rotating shaft 52 through the window part 35. Therefore, the worker can check whether the proper rotating shaft 52 is attached to the board case portion 50, whether bolts, etc. that are different from the genuine parts of the gaming machine 1 are attached, etc. This allows the worker to check that the main control board 11, etc. have not been tampered with.

[0031] As shown in FIGS. 16, 17 and other figures, the substrate case part 50 includes a rear case part 51 and a front case part 55. As shown in FIG. The rear case part 51 and the front case part 55 are case parts on the rear side Y2 (second surface side) and the front side Y1 (first surface side) of the board case part 50. Various parts (e.g., components of the lock part 17, etc.) are attached to the rear case part 51 and the front case part 55, but in the embodiment, the term "case part" refers not only to the case member alone but also to the state in which the various parts are attached. Although detailed description is omitted, the rear case part 51 and the front case part 55 are joined in an inseparable manner by fitting the lower part with a claw or the like and joining the upper part with a fastening member 50d (see FIG. 16, etc.) or the like. Hereinafter, such a configuration in which the case parts are joined in an inseparable manner with the fastening member 50d or the like is also referred to as "crimping". The rear case part 51 and the front case part 55 have a box-like outer shape that opens on the front side Y1 and the rear side Y2, respectively, to accommodate the main control board 11. The rear case part 51 and the front case part 55 are molded products made of a transparent resin material, or the like. Therefore, the accommodated main control board 11 can be seen from the outside of the rear side Y2 and the front side Y1 of the board case part 50.

[0032] The rear case portion 51 includes a rotating shaft 52, a rotating shaft attachment portion 53a, and a connecting member attachment / detachment portion 53e. The rotation shafts 52 are attached to the left and right sides of the board case portion 50, respectively. The rotating shaft 52 is manufactured by processing, for example, a metal (stainless steel, iron, etc.). 18, the rotating shaft 52 is a thin, flat, rivet-like member in which a flange-shaped head 52b is provided on a shaft portion 52a. The tip of the rotating shaft 52 is flat, with both sides machined into a D-cut shape.

[0033] The rotating shaft 52 has a hole 52c. The hole 52c is a hole that penetrates the tip of the flat plate-shaped shaft portion 52a in the thickness direction. The rotating shaft attachment portion 53a is a portion for attaching the rotating shaft 52 to the rear case portion 51. The rotating shaft attachment portions 53a are provided at the left and right corners of the lower side Z1 of the rear case portion 51 (see FIG. 16).

[0034] As shown in FIG. 18, the rotating shaft attachment portion 53a has a shaft insertion hole 53b and a pilot hole 53c. The shaft insertion hole 53b is a through-hole that penetrates lower portions of the left and right side portions of the rear case portion 51 in the left-right direction X. The shaft portion 52a of the rotation shaft 52 is inserted into the shaft insertion hole 53b. The pilot hole 53c is a hole for screwing the tip of the shaft portion 52a of the rotating shaft 52. The pilot hole 53c is provided in the range of the left and right corners of the lower side Z1 of the bottom portion (the plate portion on the rear side Y2) of the rear case portion 51. The pilot hole 53c is a bottomed hole portion formed by recessing the inner surface (the front side Y1) of the bottom portion toward the rear side Y2. As shown in Figure 18 (B), the rotating shaft 52 is screwed to the rear case part 51 using the hole part 52c and the pilot hole 53c of the rear case part 51, with the shaft part 52a inserted into the shaft insertion hole 53b of the rear case part 51.

[0035] With the above-described configuration, the rotating shaft 52 is fixed to the substrate case part 50 so as to protrude in the left-right direction X from a corner part on the lower side Z1 of the substrate case part 50. When the rotating shaft 52 is fixed to the substrate case part 50, a part of the shaft part 52a and the head part 52b are disposed outside the substrate case part 50. In addition, in the state of the board case part 50, the screws for fixing the rotating shaft 52 are located inside the rear case part 51 and the front case part 55 and cannot be accessed from the outside. This makes it possible to prevent the act of removing the rotating shaft 52 for fraudulent purposes, etc.

[0036] As shown in FIGS. 19, 20, etc., the joining member attachment / detachment portion 53e is a portion for detachably attaching the joining member 70R. Here, when the gaming machine 1 is shipped, the coupling member 70R is attached to the coupling member fixing portion 21g of the base case portion 21, and is thus incorporated in an inseparable manner. In contrast, the reason why the coupling member 70R is detachably attached to the coupling member attachment / detachment portion 53e is to mark the board identification information on the coupling member 70R in a state where the coupling member 70R is attached to the board case portion 50, as described later.

[0037] The coupling member attachment / detachment portion 53e is provided in the center of the bottom side 51d of the rear case part 51. When the board case part 50 is in a standalone state (before the board case part 50 is attached to the base part 20), the bottom side 51d protrudes like a brim onto the bottom side Z1 of the rear case part 51. Therefore, when the board case part 50 is in a state, the coupling member attachment / detachment portion 53e is exposed to the front side Y1 and is accessible.

[0038] The joining member attachment / detachment portion 53e includes a groove portion 53f and a semicircular ring-shaped protrusion 53g. The groove 53f is a groove provided in the lower side 51d. A rib of the connecting member 70R is inserted into the groove 53f. The shape of the groove 53f when viewed from the front side Y1 is an upside-down U-shape. The semicircular annular protrusion 53g is a protrusion that protrudes from the lower side portion 51d to the front side Y1. An inner diameter portion of the screw head cover portion 75 of the coupling member 70R is inserted into the semicircular annular protrusion 53g. The shape of the semicircular annular protrusion 53g when viewed from the front side Y1 is semicircular annular.

[0039] As shown in FIG. 17, the front case portion 55 has a pilot hole 55a. The pilot holes 55a are holes for fixing the main control board 11 with screws. The main control board 11, while housed in the front case portion 55, is fixed to the front case portion 55 from the rear side Y2 using screws provided in the pilot holes 55a.

[0040] (Connecting members 70L, 70R) FIG. 21 is a view showing the connecting member 70R alone according to the embodiment. FIG. 21(A) is a view seen from the left side X1. FIG. 21B is a view seen from the front side Y1. FIG. 21C is a view seen from the right side X2. FIG. 21(D) is a view seen from the rear side Y2. FIG. 21E is a cross-sectional view taken along line E-E of FIG. 21B. 21(F) and 21(G) are perspective views seen from the upper left and upper right of the front side Y1, respectively. The joining member 70R is a member that protects the base portion 20 from being removed from the rear plate 2c, and also protects the board case portion 50 from being removed from the base portion 20.

[0041] The connecting members 70L and 70R are molded products made of a light-transmitting resin or the like. The outer shape of the connecting member 70R is such that the rear plate portion 70b and the front plate portion 70f are arranged in a stepped shape. In other words, the connecting member 70R is such that the rear plate portion 70b, the standing wall portion 70a, and the front plate portion 70f are connected to each other so as to have a Z-shaped cross section. The joining member 70R includes a rib 71, claw portions 72h, 72i, and 72j, a stopper 74, and a screw head cover portion 75 (first protection region). The stopper 74 is disposed sufficiently close to the screw head cover portion 75 (first protection region).

[0042] The ribs 71 are provided so as to protrude from the upper and lower parts of the rear plate portion 70b toward the rear side Y2. The claw portions 72h, 72i are provided on the rib 71. The claw portions 72h, 72i are provided so as to protrude from the rib 71 outward in the vertical direction (to the lower side Z1 and the upper side Z2). The claw portions 72j are provided on the ribs 72a that protrude from the left and right outer ranges of the front plate portion 70f to the rear side Y2. The claw portions 72j are provided so as to protrude outwardly from the ribs 72a.

[0043] 12, in a state where the joining member 70L is attached to the joining member fixing portion 21g of the base portion 20, the flange portion 72b of the rear plate portion 70b is disposed on the front side Y1 of the claw portions 72h, 72i (see FIG. 12(B)), and the flange portion 72f of the front plate portion 70f is disposed on the front side Y1 of the claw portion 72j (see FIG. 12(D)). Note that FIG. 12 shows an example of the joining member 70L, but the joining member 70R is similar. In addition, the portion of the base case 21 that houses the flanges 72b and 72f is a step that is one step lower than the surrounding area, and the upright wall of the step surrounds the flanges 72b and 72f. Therefore, the claws 72h, 72i, and 72j cannot be accessed from the outside. This allows the coupling member 70L to be coupled to the base 20 in an inseparable manner. This is because when attempting to separate the coupling member 70L from the base 20 for fraudulent purposes, it is necessary to destroy the flanges 72b and 72f and then access the claws 72h, 72i, and 72j.

[0044] As shown in FIG. 21, the stopper 74 is provided in the form of a rib protruding from the standing wall portion 70a to the lower side Z1. 12(C), in a state where the coupling member 70L is attached to the coupling member attachment / detachment portion 53e of the base portion 20, the stopper 74 is disposed in a position to close the insertion / removal hole 32a of the guide groove 32 of the rail portion 30L. Note that, although FIG. 12 shows an example of the coupling member 70L, the same applies to the coupling member 70R. As a result, the stopper 74 functions as a restricting portion that restricts the upward movement range of the rotating shaft 52 of the board case portion 50 , and also functions as a retainer for preventing the rotating shaft 52 from slipping out of the guide groove 32 . Furthermore, like the claw portion 72j, the stopper 74 cannot be accessed from the outside due to the flange portion 72f of the base case portion 21, the step portion of the base case portion 21, and the like (see FIG. 12(D)). For this reason, in order to remove the rotating shaft 52 of the board case portion 50 from the guide groove 32 of the rail portion 30L, it is necessary to destroy the flange portion 72f and the like. As a result, the stopper 74 protects the rotating shaft 52 so that it cannot be separated from the rail portion 30L, and can suppress the act of removing the board case portion 50 from the base portion 20 for unauthorized purposes, etc. In this manner, the area A74 (second protection area) near the stopper 74 is configured so that the rotating shaft 52 cannot be separated from the guide groove 32.

[0045] 21, the screw head cover portion 75 is a cylindrical portion of the rear plate portion 70b that protrudes toward the front side Y1. The front portion of the cylinder forms a top portion (front portion) and has a closed shape. 12, when the coupling member 70L is attached to the coupling member attachment / detachment portion 53e of the base portion 20, the top portion of the screw head cover portion 75 covers the head of the screw 20a from the front side Y1. Therefore, the head of the screw 20a cannot be accessed from the outside. As a result, the screw head cover portion 75 makes it impossible to release the connection between the base portion 20 and the back plate 2c. In other words, when attempting to remove the base portion 20 from the back plate 2c for fraudulent purposes, it is necessary to destroy the screw head cover portion 75 before accessing the head of the screw 20a. Furthermore, since the screw head cover portion 75 is translucent, an operator can check whether the screw 20a is properly attached.

[0046] In this way, the screw head cover portions 75 of the coupling members 70L, 70R must be destroyed in order to remove the base portion 20 from the housing 2. Also, the area A7 near the stopper 74 of the coupling members 70L, 70R must be destroyed in order to remove the board case portion 50 from the base portion 20. Therefore, the coupling members 70L, 70R can be used both as a member for preventing the base portion 20 from being removed and as a member for preventing the board case portion 50 from being removed.

[0047] 12(A), when viewed from the front side Y1, the screw head cover part 75 and the area A74 near the stopper 74 are located outside the board case part 50, and can be seen. The screw head cover part 75 and the area A74 are provided on the same member, the connecting member 70L, and are therefore close to each other. Therefore, by checking the connecting member 70L, the worker can immediately check whether there is an abnormality in both the screw head cover part 75 and the area A74.

[0048] As described later, when the gaming machine 1 is manufactured, the connecting member 70R is detachably attached to the connecting member attachment / detachment portion 53e of the board case portion 50, that is, temporarily attached. 19 and 20, in this case, the rib 71 of the coupling member 70R is press-fitted into the groove 53f of the coupling member attachment / detachment portion 53e, and the cylindrical portion of the screw head cover portion 75 is press-fitted into the semicircular annular protrusion 53g. Furthermore, the claw portions 72h, 72i of the coupling member 70R are weakly pressed down by the claw portion 53h (see FIG. 20(D) and the like) provided in the groove portion 53f of the coupling member attachment / detachment portion 53e. As a result, the coupling member 70R is detachably attached to the board case portion 50.

[0049] (Operation when rotating and sliding the board case part 50) A series of operations during rotation and sliding of the board case part 50 will be described with reference to FIGS. 8 to 10, 22 to 24, etc. 22 to 24 are diagrams illustrating the manner in which the substrate case part 50 of the embodiment moves (rotates and slides) relative to the base part 20. FIG. 22 to 24, the internal configurations of the board case portion 50 and the base portion 20 are omitted as appropriate, and only their external shapes are shown to explain the positional relationship between them. FIG. 22 is a diagram for explaining a state in which the vicinity of the rotation shaft 52 of the board case part 50 slides along the guide groove 32 of the base part 20. As shown in FIG. FIG. 22A is a view of the vicinity of the board case part 50 in a rotated state (rotated by 90 degrees) as viewed from the left side X1. FIG. 22B is a cross-sectional view (corresponding to the BB cross-sectional view in FIG. 22A) of the vicinity of the rotation shaft 52 of the substrate case part 50 and the vicinity of the guide groove 32 of the base part 20. FIG. 23 is a diagram illustrating a state in which the board case part 50 is arranged in a fixed position, and a state in which the board case part 50 rotates and slides away from the drum unit 6. As shown in FIG. FIG. 24 is a diagram illustrating a configuration in which the state in which the board case part 50 has been rotated and moved is maintained. FIG. 22A is a view of the vicinity of the board case part 50 as viewed from the left side X1. FIG. 22B is a perspective view of a part of the board case 50 (near the locking portion) as viewed from the front side Y1 and upper left.

[0050] 10(B) and 10(C), when the locking portion 17 is released with the substrate case portion 50 in a fixed position, the restriction on rotation of the substrate case portion 50 is released, and the substrate case portion 50 is allowed to rotate about the axis of the rotation shaft 52 so as to fall toward the front side Y1. When the substrate case portion 50 is rotated toward the front side Y1, the upper portion of the substrate case portion 50 is disposed outside the recessed portion 21a. As a result, the restriction on movement of the substrate case portion 50 toward the upper side Z2 is released, and the substrate case portion 50 is allowed to slide toward the upper side Z2. 22(A), the rotating shaft 52 moves along the guide groove 32. As a result, the rotating shaft 52 is guided so as to be slidable in the vertical direction Z, and the board case part 50 is guided so as to be slidable in the vertical direction Z.

[0051] As shown in Figure 22 (B), when the board case part 50 slides, in addition to the shaft part 52a of the rotating shaft 52 of the board case part 50 slidingly contacting the inner surface of the guide groove 32, the head part 52b slidingly contacts the rail part 30L, and the outer surface 50a of the board case part 50 (the outer surface near the shaft mounting part) slidingly contacts the rail part 30L. Since the rail portion 30L is a molded product of a resin material containing POM, the board case portion 50 can slide smoothly without getting caught, and even if it does get caught, it can slide easily enough to provide good workability. In other words, the rail portion 30L has a degree of slidability that allows such sliding movement.

[0052] As shown in Figures 9 and 22(B), when sliding the substrate case part 50, the substrate case part 50 cannot be moved parallel to the vertical direction Z, and may tilt slightly and rotate, for example, around an axis in the front-to-rear direction Y (see arrow θ50). In such a case, the rotating shaft 52 (shaft portion 52a, head portion 52b), the outer surface 50a of the board case portion 50, etc. come into contact with the rail portion 30L with a large pressure. Even in such a case, the rail portion 30L has sufficient slidability, so that it is possible to prevent the board case portion 50 from getting caught when sliding. The above example relates to the sliding movement between the rail portion 30L and the board case portion 50, but the same applies to the sliding movement between the rail portion 30R and the board case portion 50.

[0053] 23(A), depending on the model of the gaming machine 1, components such as the drum unit 6 are arranged in the space immediately in front of the board case part 50 and on the lower side Z1. In the case of such a model, the board case part 50 arranged in a fixed position may be rotated slightly and then slid to the upper side Z2. 23(B), this allows the substrate case part 50 to be rotated widely without interfering with the drum unit 6, etc. In this way, the worker can move the substrate case part 50 by appropriately combining rotational movement and sliding movement.

[0054] As shown in Fig. 24(A), when the rotation shaft 52 is positioned in the inclined groove 32d of the guide groove 32 and the board case part 50 is rotated by 90 degrees or more so as to fall to the front side Y1, the left and right contact parts of the board case part 50 contact the front plate part 20f of the base part 20. The contact part on the left side X1 is a corner part 50b (shown by a thick line in Fig. 24(B)) at the bottom of the locking part in the front part of the board case part 50. The contact part on the right side X2 is a flange part 50c (see Figs. 15 and 16) protruding from the board case part 50 to the right side X2, a detailed description of which will be omitted.

[0055] 24(A), the mass of the board case part 50 is sufficiently larger on the right side than on the left side of the corner 50b. Also, the shaft part 52a of the rotating shaft 52 is in contact with the inner surface of the inclined groove 32d in the direction A32d toward the front side Y1 and the lower side Z1. In this state, the board case part 50 tries to fall toward the front side Y1 with the corner part 50b as a fulcrum (see arrow θ32d). In addition, a sufficiently large frictional force acts on the corner part 50b of the board case part 50 and the front plate part 20f of the base part 20, so that the corner part 50b is unlikely to slide against the front plate part 20f. The rotating shaft 52 is caught in the inclined groove 32d, so that it is unlikely to move toward the lower side Z1. Therefore, even if the worker releases the board case part 50, the board case part 50 remains rotated and disposed in the position shown in FIG.

[0056] This improves the ease of checking the back surface of the main control board 11 through the rear case part 51 of the board case part 50. In this embodiment, the state in which the board case part 50 is kept rotated is a state in which it is rotated 90 degrees or more to the front side Y1. This further improves the ease of checking the back surface of the main control board 11 from the front side Y1.

[0057] (Configuration of Board Identification Information) The configuration of the board identification information will be described. FIG. 25 is a diagram for explaining the configurations of a front case representation portion 91, a rear case representation portion 92, and a connecting member representation portion 93 of the embodiment. FIG. 25A is a view of the vicinity of the front case notation portion 91 as viewed from the front side Y1. FIG. 25B is a cross-sectional view taken along line BB of FIG. 25A. FIG. 25C is a view of the vicinity of the rear case notation portion 92 as viewed from the front side Y1. FIG. 25D is a view of the vicinity of the connecting member notation portion 93 as viewed from the front side Y1. 25 shows a state in which the coupling member 70R is attached to the coupling member attachment / detachment portion 53e of the board case portion 50. As shown in FIG.

[0058] The board identification information is information for identifying main control board 11. In the embodiment, an example will be described in which board identification information is not provided to main control board 11 itself, but is provided to board case part 50 that houses main control board 11, thereby providing board identification information to an integrated component of main control board 11 and board case part 50. In the embodiment, an example in which the board identification information is represented by five characters will be described, but the present invention is not limited to this, and the board identification information may be coded into a one-dimensional code, a two-dimensional code 520a, etc. The characters are a concept that includes various symbols, numbers, etc. The gaming machine 1 is equipped with a front case marking section 91 (first specific identification information marking section), a rear case marking section 92 (second specific identification information marking section), and a connecting member marking section 93 (identification information marking section) as marking sections on which board identification information is displayed. As described later, board identification information is marked on these markings.

[0059] The front case notation portion 91 and the rear case notation portion 92 are provided in the upper right and lower left ranges, respectively, when the board case portion 50 is viewed from the front side Y1 (see FIGS. 2 and 15). The front case notation portion 91 is provided on a front plate portion of the front case part 55. Therefore, when the board case part 50 is viewed from the front side Y1, the front case notation portion 91 is exposed to the front side Y1. The front case marking portion 91 has five unit printed portions 91a corresponding to the five characters (FIGS. 25(A) and 25(B) show one unit printed portion 91a surrounded by a two-dot chain line). Each unit printed portion 91a is marked with one character.

[0060] 25(B), the vertical cross-sectional shape of the unit print part 91a has a front surface (case front surface) that is arc-shaped and convex toward the front side Y1, and a rear surface (case back surface) that is flat. Thus, the front surface of the vertical cross-sectional shape is a curved surface (three-dimensionally shaped part). In the marking process, the laser light L is irradiated toward each unit print portion 91a in parallel with the front-rear direction Y. As a result, the marked characters are in a beautiful font without distortion when the front case marking portion 91 is observed from the front side Y1.

[0061] 25(C), the configuration and shape of the rear case notation portion 92 are similar to those of the front case notation portion 91 of the front case part 55. That is, the rear case notation portion 92 has five unit print portions, and the front side Y1 of the vertical cross-sectional shape is arc-shaped. The rear case notation portion 92 of the rear case part 51 is provided on a flange portion 51a of the rear case part 51 that protrudes toward the left side X1 (see FIGS. 16 and 17). When the board case part 50 is viewed from the front side Y1, the flange portion 51a protrudes toward the left side X1 beyond the outer shape of the front case part 55 (see FIG. 15). Therefore, when the front case part 55, the rear case part 51, etc. are integrated into the board case part 50, the rear case notation portion 92 is exposed to the front side Y1 and can be observed from the front side Y1.

[0062] As shown in FIG. 25(D), the connecting member notation portion 93 is a part of the top surface (front surface) of the screw head cover portion 75 of the connecting member 70R.

[0063] Due to the above-mentioned shapes, the front case marking portion 91, the rear case marking portion 92, and the connecting member marking portion 93 are highly effective in preventing tampering with the main control board 11. For example, in order to mark other board identification information after erasing the printing on the front case marking portion 91, the rear case marking portion 92, and the connecting member marking portion 93 by grinding, cutting, or the like for fraudulent purposes, a laser marker 100, which will be described later, is required. Such laser markers 100 are not widely distributed for consumer use, and are difficult to obtain because of their high cost. Even if printing is attempted using a laser marker 100 that transfers and ejects ink, the surfaces of the front case marking portion 91 and the rear case marking portion 92 are curved, so that distortion and bleeding of the characters will occur. Furthermore, even if other board identification information is marked on the back side, the lens effect caused by the curved surfaces of the front case marking portion 91 and the rear case marking portion 92 will still cause distortion of the characters.

[0064] In addition, even if two board case parts 50 are prepared, one board case part 50 is broken only in the front case part 55 and separated without breaking the rear case part 51, and the other board case part 50 is broken only in the rear case part 51 and separated without breaking the front case part 55, and then the unbroken rear case part 51 and the front case part 55 are combined together to assemble the board case part 50 illegally, the board identification information of the front case marking part 91 and the rear case marking part 92 will not match. For this reason, the worker can determine that such a board case part 50 is not proper. In addition, even if the board identification information of the front case marking part 91 and the rear case marking part 92 match, as described above, it is not possible to mark neatly by tampering with the board identification information, and the worker can determine that such a board case part 50 is not proper. This allows the gaming machine 1 to ensure that the rear case portion 51 and the front case portion 55 correspond to each other based on the board identification information.

[0065] Furthermore, since the coupling member 70R is attached to the base portion 20 in an inseparable manner, the integrity of the board identification information of the coupling member notation portion 93 and the housing 2 is guaranteed. Therefore, the integrity of the board identification information of the front case notation portion 91 and the rear case notation portion 92 and the board identification information of the housing 2 (i.e., the board identification information of the coupling member notation portion 93) is guaranteed. Here, in order to remove the base portion 20 and the board case portion 50 integrally from the rear plate 2c, it is necessary to remove the screws 20a (see the double-dashed lines in FIGS. 4 and 6). Since the screw head cover portion 75 of the connecting member 70R is disposed immediately before the upper right screw 20a, in order to remove this screw 20a, it is necessary to destroy the screw head cover portion 75. Since the connecting member notation portion 93 is provided on the screw head cover portion 75 of the connecting member 70R, destroying the screw head cover portion 75 will destroy the connecting member notation portion 93. For this reason, it is not possible to mark the board identification information on the connecting member notation portion 93 for fraudulent purposes, and as described above, the board identification information displayed on the connecting member notation portion 93 is difficult to reproduce because it is marked with the laser light L. This makes it possible to prevent the base unit 20 from being removed from the housing 2 for fraudulent purposes or the like.

[0066] [Installation process] The worker can follow the procedure below to attach the base portion 20 and the board case portion 50 to the back panel 2c of the gaming machine 1. Note that the following procedure is an example, and the order of the procedures may be changed as appropriate. (Assembly of the base portion 20) (1) The rail portions 30L and 30R are screwed to the base case portion 21 to assemble the base portion 20 (see FIGS. 5 and 7, etc.). (2) Then, the base portion 20 is fixed to the rear plate 2c of the housing 2 with screws (see FIG. 6, etc.).

[0067] (Assembly of the board case part 50) (1) The rotating shaft 52 is fixed to the rear case portion 51 with screws (see FIG. 18, etc.). (2) With main control board 11 housed in front case portion 55, main control board 11 is fixed to front case portion 55 with screws. Although detailed description is omitted, various other components (lock claw 18 (see FIG. 10), rotating shaft 52, etc.) are also incorporated into rear case portion 51 and front case portion 55.

[0068] (3) The rear case portion 51 and the front case portion 55 are joined together (see FIG. 16, etc.). The rear case part 51 and the front case part 55 are joined in an inseparable manner using fastening members 50d and the like. Therefore, once joined, in order to disassemble or separate the rear case part 51 and the front case part 55, the case parts must be destroyed. Therefore, if the main control board 11 or the like is illegally replaced or modified, traces of the destroyed case will remain. This provides a deterrent effect to prevent such illegal acts.

[0069] (4) The coupling members 70L and 70R are attached to the coupling member attachment / detachment portions 53e of the board case portion 50 (see FIGS. 19 and 20). (5) With the connecting members 70L, 70R attached to the connecting member attachment / detachment portion 53e of the board case portion 50, the same board identification information is marked on the front case notation portion 91, the rear case notation portion 92, and the connecting member notation portion 93 with laser light L. In this state, the front case notation portion 91, the rear case notation portion 92, and the connecting member notation portion 93 face the same direction (the front side Y1). This allows the marking process to be performed in one step, and also eliminates the need for the complicated work of combining components having the same board identification information while checking the board identification information of each component.

[0070] (Installation of the board case part 50 into the base part 20) (1) The rotation shaft 52 of the board case portion 50 is inserted into the rail portions 30L and 30R. Before the coupling members 70L, 70R are attached to the base portion 20, the insertion hole 32a of the guide groove 32 of the rail portions 30L, 30R is open (see the area surrounded by the two-dot chain line in FIG. 6). The rotation shaft 52 of the board case portion 50 can be inserted into the guide groove 32 of the rail portions 30L, 30R from the insertion hole 32a.

[0071] (2) As shown in FIGS. 6 and 12, the connecting members 70L and 70R are fixed to the connecting member fixing portions 21g of the base portion 20 by pushing them in from the front side Y1. The coupling member 70R can be removed from the coupling member attachment / detachment portion 53e when the board case part 50 is assembled into the base part 20. This facilitates management for associating the base part 20 (i.e., the housing 2) with the board case part 50 (i.e., the main control board 11) during manufacturing.

[0072] As a result of the above, the base portion 20 and the board case portion 50 can be attached to the rear plate 2c in an inseparable manner.

[0073] (500 crimping record stickers) Incidentally, as mentioned above, the board case portion 50 (board case) which houses the main control board 11 (control board) has a crimped usage record sticker 500 (specific information display portion) affixed to its center as a countermeasure against unauthorized opening of the board case portion 50 (see Figure 2, etc.). As shown in FIG. 26, the crimping use record sticker 500 is formed in the shape of a transparent sheet on which a table is printed for writing the date when the board case part 50 was sealed, etc.

[0074] Specifically, the crimping usage record sticker 500 is a sticker having a board identification information area 510, a two-dimensional code area 520, a person in charge information display area 530, etc. on the front side, and is formed from a PET material or the like with an adhesive or the like applied to the back side so that it can be affixed to the board case part 50. In addition, in these areas, a non-transparent base print is applied with white ink, which is easy to apply, on the upper surface of the transparent, light-transmitting seal (see the hatched areas in Figure 26, etc.).

[0075] The board identification information area 510 displays the above-mentioned board identification information for identifying the main control board 11 and the board case portion 50. In the two-dimensional code area 520, a two-dimensional code 520a such as a QR code (registered trademark) in which the board identification information is recorded is displayed. That is, based on this two-dimensional code 520a, markings are applied to the front case marking portion 91, the rear case marking portion 92, and the connecting member marking portion 93 (see FIG. 25, etc.). In the following description, the front case notation portion 91, the rear case notation portion 92, and the connecting member notation portion 93 are collectively referred to as the "notation portion." The person in charge information display area 530 displays information about sealing performed by crimping the board case part 50 using the fastening members 50d or the like. The information regarding the seal includes manufacturer information 530a, date information 530b, and person in charge information 530c.

[0076] The manufacturer information 530a is information relating to the gaming machine manufacturer that manufactures and sells the gaming machine 1. The date information 530b is information about the date when the person in charge sealed the crimped portion of the board case part 50, etc. The person in charge information 530c is information relating to the person in charge or the main department who inspected the gaming machine 1 and sealed the crimped portion of the board case portion 50 before shipment. In the following description, the manufacturer information 530a, the date information 530b, and the person in charge information 530c are collectively referred to as "stamped information" because they are written on the crimping usage record sticker 500 by the worker by stamping or the like.

[0077] (Laser Marker 100) In the embodiment, the board identification information of the marking section and the printing information of the person in charge information display area 530 are marked by a laser marker 100, thereby providing a gaming machine 1 with a simplified manufacturing process. FIG. 27 is a diagram showing an example of a schematic configuration of a laser marker system S, and shows a configuration in which a substrate case part 50 is transported along a transport direction D by a conveyor C.

[0078] The laser marker 100 is a device that performs printing processing (hereinafter also referred to as "marking" or "printing") on a specified irradiation area R according to a printing pattern such as letters, figures, symbols, codes, etc. by irradiating the irradiation area R with laser light L. Here, the predetermined irradiation area R is an area set on the surface of the substrate case part 50, and is an area corresponding to a marking surface set in advance on the surface of the substrate case part 50. The irradiation area R as the marking surface can take various forms depending on the specifications of the laser marker 100, the positional relationship between the laser marker 100 and the substrate case part 50, and the like.

[0079] In addition, the laser marker 100 is connected to a setting device (not shown) consisting of, for example, a personal computer or a console, and the operator inputs printing parameters such as the laser power indicating the target output of the laser light L and the scan speed indicating the scanning speed of the laser light L while referring to the monitor of this setting device. The laser marker 100 is then controlled in accordance with the printing parameters inputted into the setting device. Such a laser marker 100 includes a laser controller 100a and a laser head 100b, which are connected by a cable (not shown). The laser controller 100a and the laser head 100b may be integrated into one unit.

[0080] The laser controller 100a (control device) controls the laser head 100b in accordance with the printing parameters set by the setting device, thereby marking the board identification information read by the barcode reader 200 with the laser light L. In addition, a barcode reader 200 is provided as an external device. The laser controller 100a reads the two-dimensional code 520a printed on the crimping usage record sticker 500 attached to the board case part 50 transported by the conveyor C using the barcode reader 200, and receives the board identification information (unique information) as the reading result.

[0081] The laser head 100b irradiates a laser beam L toward a predetermined irradiation area R under the control of the laser controller 100a based on the printing parameters. For details of the configuration of the laser marker 100, for example, the configuration of JP 2008-227378 A and the like are incorporated by reference.

[0082] (Marking process) The laser marker 100 configured in this manner performs a marking process on both the board case portion 50 itself and the crimping use record sticker 500 affixed to the board case portion 50 . The marking process will be described below with reference to the flowchart shown in FIG.

[0083] First, in S10, printing parameters are set. The laser marker 100 sets the printing parameters input by the operator as printing conditions. An operator sets printing parameters for the laser marker 100 for performing marking via a setting device, and the marking is performed in accordance with the printing parameters set in advance. For example, using a green laser with a wavelength of 532 nm, the following printing parameters are set as shown in FIG. Lasers with wavelengths other than the green laser, such as an infrared laser with a wavelength of 1064 nm or an ultraviolet laser with a wavelength of 355 nm, may also be used.

[0084] (a) Printing parameters for the substrate case part 50 Laser power: 30% of average output of 6W Scan speed: 1000mm / sec Number of prints: 7 (b) Printing parameters of the crimping use record sticker 500 Laser power: 80% of the average output of 6W (prescribed output value) Scan speed: 1000mm / sec Number of times printed: 1 time (predetermined number of times)

[0085] The laser power for the board case part 50 is set lower than the laser power for the crimping use record sticker 500 . Therefore, the board identification information in the display section of the board case section 50 is marked with a lower laser power than the stamped information in the person in charge information display area 530 of the crimped use record sticker 500. This setting allows clear marking without damaging the irradiation area R of each of the crimping use record sticker 500 and the board case part 50.

[0086] The scanning speeds of the crimping usage record sticker 500 and the board case part 50 are set to be the same. This setting ensures that the markings are clear and do not smudge.

[0087] The number of times printing is performed on the board case part 50 is set to be greater than the number of times printing is performed on the crimping use record sticker 500. Therefore, the board identification information in the display section of the board case section 50 is marked by irradiation more times than the stamped information in the person in charge information display area 530 of the crimped use record sticker 500. This setting allows the marking density (depth) and marking quality to be maintained without concentrating the marking.

[0088] By setting such printing parameters, high speed printing is possible without causing significant damage to the board case portion 50, the crimping use record sticker 500, etc., and the marking process can be performed clearly.

[0089] In S11, the barcode reader 200 acquires unique information (substrate identification information). Barcode reader 200 reads two-dimensional code 520 a for identifying main control board 11 and board case portion 50 , which is written on crimping usage record sticker 500 . Then, the barcode reader 200 transmits the read content to the laser controller 100a.

[0090] In S12, the password is changed to a unique number of a predetermined number (for example, five digits (five characters)). The program numbers stored in the laser controller 100a are changed to unique numbers based on the two-dimensional code 520a read by the barcode reader 200. Here, the unique number is specific information for distinguishing the main control board 11 and the board case unit 50 from those provided in other gaming machines 1.

[0091] In S13, the laser head 100b irradiates the laser light L based on the set printing parameters. The laser head 100b irradiates the laser light L onto the display section of the board case section 50 and the person in charge information display area 530 of the crimping use record sticker 500 attached to the board case section 50, thereby performing marking. The markings are, for example, in black or red.

[0092] (Marking order) In this case, the marking will be done in the following order: FIG. 30 is a diagram for explaining the order of marking on the board case part 50 and the crimping use record sticker 500 to be affixed to the board case part 50, and the numbers in the figure respectively indicate the order of marking. When there are four marking locations (substrate case portion 50 of the present invention), the laser marker 100 marks unique numbers in order at locations (1) to (3) as shown in Figure 30(a), and then marks the printing information at location (4). When there are six marking locations, the laser marker 100 marks unique numbers in order at locations (1) to (5) as shown in FIG. 30(b), and then marks the printing information at location (6). That is, the laser marker 100 is controlled to mark the unique number and then to mark the imprint information. Therefore, the manufacturer information 530a, the date information 530b, and the person in charge information 530c on the crimping usage record sticker 500 are marked by the laser marker 100 after the board identification information (unique number) on the board case part 50. As a result, if marking on the board case part 50 side fails, marking can be immediately stopped and the crimping use record sticker 500 can be reattached to another board case part 50, thereby preventing waste of the crimping use record sticker 500 on the board case part 50 where marking has failed. Furthermore, the date information 530b is automatically updated by a program-managed calendar using a real-time clock (RTC) function built into the laser marker 100, so no effort is required. The base portion 20 may be included in the substrate case portion 50 (substrate case).

[0093] (marking depth) Also, the laser marker 100 marks the imprinting information without penetrating the crimped usage record sticker 500 as shown in FIG. Specifically, the marking is made so as to penetrate the white layer 500a, which is undercoated with white ink and printed on the crimped use record sticker 500, without penetrating the transparent layer 500b. This can be achieved by irradiating the crimping use record sticker 500 with high-output laser light L, as compared with the board case part 50, only once. In other words, the stamping information including the person in charge information 530c is marked by the laser marker 100 in such a manner that the laser light L does not penetrate the crimped usage record sticker 500 and does not reach the board case part 50. This allows the marking to be secured inside the usage record sticker 500 by crimping, allowing for uniform and clear marking. Therefore, the marking depth can be stabilized, and the readability of the imprinted information can be improved compared to irradiating the low-output laser light L multiple times. The laser marker 100 need not penetrate the crimping use record sticker 500, and may mark, for example, so as not to penetrate the white layer 500a, that is, so as not to reach the transparent layer 500b.

[0094] As described above, in the gaming machine 1 of the embodiment, the board identification information on the display section of the board case section 50 and the printing information on the crimping usage record sticker 500 are marked by the laser marker 100, so that the date information 530b is automatically updated, and printing errors and initial costs such as ink can be reduced compared to handwriting or stamping by an operator. Furthermore, since there is no need for workers to perform tasks such as handwriting or stamping, the manufacturing process can be simplified, and as a result, manufacturing costs can be reduced.

[0095] In contrast, in conventional gaming machines, the operator had to handwrite or stamp date information 530b and person in charge information 530c, etc. on the crimped usage record sticker 500 with a writing instrument, which sometimes led to stamping errors and resulted in a lot of work.

[0096] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible. Note that the configurations of the above-described embodiment and the configurations of the modified embodiments described below can be used in appropriate combination, but detailed description thereof will be omitted.

[0097] (1) In the embodiment, the case member housed inside the housing is the board case part 50 that houses the main control board 11, but is not limited to this. The case member may be any of various case members that are housed inside the housing. The case member may be, for example, the board case part 50 that houses the sub-control board 12. (2) In the embodiment, the substrate case part 50 is rotatable in the front-rear direction around an axis in the left-right direction, but is not limited thereto. The substrate case part 50 may be supported so as to be rotatable in the left-right direction around an axis in the vertical direction, for example. (3) In the embodiment, the gaming machine 1 is a slot machine, but is not limited to this. The gaming machine 1 may be, for example, a pachinko machine, a ball slot machine, or other gaming machines. (4) In the embodiment, an example is shown in which a unique number is marked on the board case part 50 and then the stamping information is marked on the crimped usage record sticker 500, but this is not limiting. The stamping information may be marked on the crimped usage record sticker 500 first, or the stamping information may be marked on the crimped usage record sticker 500 during the process of marking the unique number on the board case part 50.
