However, as shown in FIG. 5, the corner is dropped (notched) 720 in a substantially triangular shape.

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 5 is a front view showing the configuration of the game board 30. Two pairs of general winning ports 31, 31 are arranged stepwise on the left and right sides of the game board 30, and an upper start port 33a and a lower start port 33b (configured by an operation chuck 33b) are arranged at the lower center. A starting port 33 and a variable winning device 32 are arranged. The general winning ports 31, 31, the variable winning device 32, and the starting port 33 are openings that penetrate from the game area toward the back surface, and a winning device is attached to correspond to these openings. That is, a ball detection sensor corresponding to these is provided on the back surface of the game board 30, and these sensors are connected to a main control board (main control device) to be described later through an electric wiring (not shown). . A pair of opening and closing blades are provided at the entrance of the lower start port 33b, and an open position for guiding the game ball and a closed position where the game ball is difficult to enter the lower start port 33b can be taken. The opening / closing blade is driven by a solenoid disposed on the back side of the game board 30.
When a game ball enters the general winning ports 31, 31, the variable winning device 32, and the starting port 33, it is detected by each of the detection sensors, and based on the output of the detection sensor, the upper plate 19 ( Alternatively, when a predetermined number of prize balls are paid out to the lower plate 15) and a game ball enters the start port 33, a lottery to be described later is started.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated in an open state and a normal closed state in which a game ball is easy to win in a big win. It has become. Specifically, the incoming ball from the entrance of the housing portion having a width that allows a plurality of game balls to pass in the lateral direction of the game board 30 is housed in the housing portion and detected from the discharge portion provided in the housing portion. It is comprised so that it may reach a sensor and may detect. And, in the game area of the game board 30, a start port 33 for entering a game ball flowing down the flow space between the window portion 101 and the game board 30 is provided, and by entering the start port 33, The main control device performs a lottery determination with a predetermined probability, and the corresponding game state is shifted to the special game state by the corresponding lottery. In the special game state, the variable winning device 32 is in the non-ball-receiving state From the entrance of the storage unit to the ball receiving state, the specified number of winning balls stored in the storage unit is detected by the detection sensor so that a predetermined number of prize balls are paid out. It is configured.

The detection results detected by the winning sensor are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is paid out from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board.
In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

In addition, a decorative symbol display device 42 using a liquid crystal panel is disposed at the center of the game board 30, and through gates 34, 34 are disposed on the left and right side portions thereof. These through gates open and close the wings of the starting port 33 described later by passing the game ball.
In addition, a decorative member 35 having the above-described general winning ports 31 and 31 is provided at the lower left and right positions of the game board 30, and an out port 36 is provided at the lower part of the game board 30. A game ball that has not entered the apparatus or the like is guided through the out port 36 toward a ball discharge path (not shown) on the back of the game board 30. Further, the game board 30 is provided with a large number of guide nails for appropriately dispersing and adjusting the falling direction of the game balls, and a windmill having the same function.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. .

In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of a game ball. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51.
In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 5). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 5: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner side surface of the outer rail 52, a sliding plate as a long metal strip made of stainless steel is attached to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is worn.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30.

A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and serves to guide the foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage. .
Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 5) such as certificate stamps (for example, serial numbers are described) and plates. In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 5) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said.
Therefore, when it is referred to as a game area, the guide rail portion is not included, and the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail 52.

  In the resin base, below the window hole 21 (game board 30), a launch rail for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. The launch rail is fixedly attached to the resin base via a metal plate behind the launch rail, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail, and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It has come to be.

  Further, there is a gap of a predetermined interval between the launch rail and the rail unit 50 (guidance rail), and a foul ball passage is formed below this gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 15 to the lower plate 15. To be discharged.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. There is also a thing that jumps to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage. As a result, all of the foul balls are reliably guided to the foul ball passage. Interference between the ball and the next-launched game ball is suppressed.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame 14 side (ball outlet leading from the most downstream portion of the upper plate 19). Further, the game ball launching device 38 is provided with a ball striking ball, and the game ball is launched with the rotation of the ball striking center around the shaft portion.

  A reference numeral 67 in FIG. 4 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / closable shutter that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction, and has a state in which the front frame 14 is opened from the inner frame 12. In the state of FIG. 4, the shutter is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like, and the discharge port 67 is closed so that the game ball does not spill from the discharge port 67.

  Further, when the front frame 14 is closed, the shutter is pushed open by a ball passage rod 69 (see FIG. 4) provided on the back surface of the front frame 14 to be in a substantially horizontal state and discharged toward the discharge port 67. The played game balls are discharged to the upper plate 19 through the ball passageway 69 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game ball in the payout passage or the like spills out of the pachinko machine 10 when the front frame 14 is opened.

  As shown in FIG. 4, a front frame set opening detection switch 90 that detects that the front frame 14 is opened with respect to the inner frame 12 is provided on the upper side of the inner frame 12. When the front frame 14 is opened, it is output from the front frame set open detection switch 90 to the computer for the hall (in the pachinko parlor). Further, when the front frame 14 is closed, the metal reinforcing plate of the front frame 14 comes into contact with the pair of metal fittings of the inner frame 12, and the grounding of the front frame 14 is ensured.

Here, the front frame 14 described above will be described in more detail with reference to FIGS. 1 to 4.
A substantially oval window 101 is formed on the front frame 14 so that most of the game area can be viewed from the outside. Specifically, the base member includes an opening that forms the window portion 101, and a substantially central portion on the left and right sides thereof has a shape that is curved and thinned relatively gently as compared with the upper and lower sides. The substantially central portion may be linear.

In addition, the front frame 14 is provided with a light emitting portion such as various lamps as one of the effect devices 700 around the periphery (for example, a corner portion). These light emitting units play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or when the blade is opened. For example, at the periphery of the window portion 101, an annular illumination portion 102 incorporating a light emitting portion such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting unit such as an LED is provided.

The space between these support portions 413a is substantially closed, and is close to the head of a rivet that is a shaft 411 that pivotally attaches the first substrate case 201A.

  As shown in FIG. 9 to FIG. 11 and FIG. 21, the fixed end (the right end in FIGS. 9, 11 and 21) on the outer surface (side surface of the first substrate case 201A) of the intermediate member 501 has a tip. A rectangular locking piece 517 formed with a locking claw is disposed so as to protrude rearward (to the first substrate case 201A side), while the free end of the first substrate case 201A has a rectangular shape. The protruding portion 851 having a shape is disposed so as to protrude laterally (to the right in FIG. 21), and the locking piece 517 can be elastically locked to the protruding portion 851 as shown in FIG. It is like that. The locking piece 517 is integrally formed with the intermediate member 501.

  Further, as shown in FIG. 11, a rectangular recess 518 is formed at the free end portion on the outer side surface of the intermediate member 501. The rectangular recess 518 has a length (length along the longitudinal direction of the intermediate member 501) and a depth substantially equal to the length (about 48 mm) and the thickness (about 13 mm) of the connection base member 430, respectively. As shown in FIG. 9, the connecting pedestal member 430 can be accommodated in the interior with almost no gap, and the outer side surface (open side surface) of the connecting pedestal member 430 and the outer side surface of the intermediate member 501 are flush with each other in the accommodated state. It comes to become. Thereby, a gap is not formed as much as possible between the first substrate case 201A.

  Further, in the pachinko machine 10, the sealing means constituted by the first and second sealing portions 520a and 520b is provided at one end portion of the intermediate member 501 and the position of the ball assembly plate 460 corresponding thereto. Although the structure is the same, the same or different sealing means may be provided at the other end portion, thereby fixing the both ends of the intermediate member 501 in a sealed state. In this case, sealing means may be further provided at an end portion of the intermediate member 501 provided with an opening / closing structure (a structure pivotally supported), but both ends are fixed by the sealing means. The open / close structure can be omitted.

  As described above, the intermediate member 501 is interposed between the back surface of the game board 30 and the first control board unit 201, so that a gap between the back surface of the game board 30 and the first control board unit 201 is provided. As a result, a space that can be fraudulent is not formed. Further, since the intermediate member 501 is fixed in a state where it is sealed by the sealing means 520, it is difficult to remove it illegally, and even if this sealing is illegally broken, there is no trace. Since it remains, it is obvious at a glance that the seal has been broken, which makes it easy to detect fraud.

  Further, the sealing means includes a first sealing portion 520a and a second sealing portion 520b, and the first sealing portion 520a is inserted into the ball assembly plate 460 from the game board 30 side so that the intermediate member 501 is sphered. Screws 519 which are fixing means for fixing to the collective plate 460, a recess 465 provided on the bottom side of the ball collective plate 460 through which the screw 519 is inserted, and a screw 519 provided on the intermediate member 501. The ball assembly plate 460 is attached to the game board 30 because the insertion portion 514 is inserted and fixed, and the cutting portion 514A is provided in the insertion portion 514 to release the fixed state by the screw 519. In this state, it is impossible to remove the screw 519 from the outside. As a result, the intermediate member 501 is fixed in a sealed state, and if it is illegally removed without leaving any trace, It becomes necessary to remove the 460 from the game board 30, thus making it difficult to carry out the fraud. On the other hand, for example, when the intermediate member 501 is opened for the purpose of inspecting the back side of the ball assembly plate 460, the sealing state of the intermediate member 501 can be released while leaving a trace by cutting the cutting portion 514A. Further, since the intermediate member 501 can be freely opened in a state where the ball assembly plate 460 is not attached to the game board 30, workability is good.

  Further, the second sealing portion 520b is inserted into the intermediate member 501 from the back side, and a breaking screw 522 that fixes the intermediate member 501 to the ball assembly plate 460, and a hole that is provided in the intermediate member 501 and into which the breaking screw 522 is inserted. Breaking screw insertion portions 515 and 516 at the bottom, screwed portions 463 and 464 provided on the ball collecting plate 460 and into which the breaking screws 522 are screwed, and a breaking screw insertion portion for releasing the fixed state by the breaking screws 522 The intermediate member 501 can be fixed to the spherical assembly plate 460 from the outside by the breaking screw 522, and thus the intermediate member 501 can be easily fixed. It can be fixed in a sealed state. At this time, even when the ball assembly plate 460 is attached to the game board 30, the intermediate member 501 can be sealed and fixed to the ball assembly plate 460 from the outside by the break screw 522. After the sealing state by the first sealing portion 520a is released, the intermediate member 501 and the ball assembly plate 460 can be sealed again by the second sealing portion 520b. On the other hand, for example, when the intermediate member 501 is opened for the purpose of inspecting the back side of the ball assembly plate 460, the sealing state of the intermediate member 501 is released while leaving traces by cutting the cutting portions 515A and 516A. Can do.

  Furthermore, one end portion of the first control board unit 201 is pivotally attached by the shaft 411, and the breaking screw insertion portion 515 is close to the shaft 411 that pivotally attaches the first control board unit 201. Even if the first control board unit 201 is illegally removed from the pivot portion, it is difficult to remove the pivot portion due to the failure screw insertion portion 515 and the intermediate member 501 is sealed. Therefore, it is difficult to remove the breaking screw insertion portion 515 without leaving a trace even if it is attempted to remove the breaking screw insertion portion 515. Therefore, fraud is more effectively prevented.

  Further, the first sealing portion 520a is provided at the corner portion of the intermediate member 501, and the second sealing portion 520b is provided in addition to the corner portion, so that the intermediate member 501 is cornered by the first sealing portion 520a. Thus, the intermediate member 501 can be sealed more easily and reliably by the second sealing portion 520b. In addition, since the first and second sealing portions are provided at a plurality of places, if sealing and releasing are performed at one place for each time of performing sealing and releasing, sealing and releasing are performed. This process can be performed a plurality of times, and an opening history can be left for each process.

  Further, since the intermediate member 501 is formed into a hollow body and the inside is partitioned into a large number of chambers by the ribs 512, a sufficient space is provided in the intermediate member 501 to install an unauthorized substrate. Therefore, cheating can be effectively prevented.

  Further, since the intermediate member 501 has a structure in which the surface facing the ball assembly plate 460 is opened, the opened surface is also in contact with the ball assembly plate 460 and closed when the intermediate member 501 is closed. Therefore, fraudulent acts such as installing an unauthorized substrate inside the intermediate member 501 are difficult. At this time, as described above, even if the inside of the intermediate member 501 is partitioned into a large number of chambers by the ribs 512, if the open portion of the intermediate member 501 is exposed to the outside, the ribs 512 are cut from there and the illegal act is performed. However, it is also difficult to cut the rib 512 by making the open surface of the intermediate member 501 face the spherical assembly plate 460 as described above.

  Furthermore, since the intermediate member 501 and the first control board unit 201 have an open / close structure that opens and closes in the opposite direction, the intermediate member 501 and the first control board unit 201 are opened. Is not concentrated on either one of the left and right ends, but is distributed on both the left and right ends. Therefore, for example, when the intermediate member 501 and the first control board unit 201 are opened for inspection or the like, a problem such as deformation of the spherical assembly plate 460 due to the load of the intermediate member 501 and the first control board unit 201 is prevented. The If the ball assembly plate 460 is deformed, there is a risk that the game balls may be discharged.

  Further, one end of the first control board unit 201 is pivotally attached to the shaft 411 and is engaged with the intermediate member 501 to be engaged with the other end (free end) of the first control board unit 201. By adopting a configuration in which the pieces are integrally molded, it is not necessary to separately prepare a member (for example, a ny latch) for holding the free end portion of the first control board unit 201, and the number of parts can be reduced. Further, if the intermediate member 501 is illegally removed, the free end portion of the first control board unit 201 is released without being held, so that an illegal act can be easily detected, and therefore fraud is performed. It becomes more difficult.

In the assembly of the pachinko machine 10, for example, electrical components such as a relay board, LED board, switch, and wiring are attached to the ball assembly plate 460, and an intermediate member 501 is attached to the ball assembly plate 460 to form a unit. However, if this unit is attached to the game board 30 and then the first control board unit 201 is attached, the workability is improved. In such a case, at least a part of the electrical components is the intermediate member 501. By making it cover, an electrical component is protected by the intermediate member 501, and it is prevented that an electrical component is damaged at the time of an installation operation | work.
FIG. 22 shows a state in which the intermediate member 501 and the first control board unit 201 are attached to the ball assembly plate 460. In this way, the ball assembly plate 460, the intermediate member 501, and the first control board unit 201 are shown. The process of attaching 201 to the game board 30 in an integrated state is also possible, and the assembly method of the pachinko machine 10 is not limited to a specific one, but as described above, the game is performed with the ball assembly board 460 and the intermediate member 501 as a unit. The process of attaching the first control board unit 201 after being attached to the panel 30 has particularly good workability.

(Feature configuration)
In the pachinko machine 10, one side portion of the first board case 201A that forms the main part of the first control board unit 201 is supported and fixed to the back side of the game board 30 by a mounting structure including a connecting member made of metal. The other side portion of the first substrate case 201A is sealed by sticking a sticker configured to be able to transmit and receive radio waves with the outside.

  As is clear from the above description, the first substrate case 201A has a rectangular shape that is substantially horizontally long when viewed from the front, and one side portion thereof (the left side portion when viewed from the back of the first substrate case 201A) is made of a steel plate. It is supported and fixed on the back side of the game board 30 via an opening / closing mechanism 410 including a connecting member made of metal, such as a support 412 and a bracket 413.

  The first board case 201A includes the outer case (first case or second case) 70 and the inner case (second case or first case) 85 as described above. 24 and FIG. 25. 24 is a perspective view of the first substrate case 201A, and FIG. 25 is an exploded perspective view of the first substrate case 201A. Note that the first substrate case 201A shown in FIGS. 24 and 25 is slightly more detailed than the embodiment described in detail with reference to FIGS. 8 to 23, such as a sealing member 87A. Are basically the same.

  As shown in FIG. 24 and FIG. 25, the first substrate case 201A is an outer case having a relatively large thickness (depth) and a substantially horizontally long rectangular shape as viewed from the back, with the front side (game board 30 side) open. 70, a control board 80 of the main control device 261 is accommodated, and a rectangular inner case 85 having a relatively small thickness and having a relatively small thickness as seen from the front side of the control board 80 is shown in FIG. As shown by an arrow A1 in 24, it is configured to be fitted by sliding in the length direction.

  In the first board case 201A, the other side part (the right side part in the rear view of the first board case 201A) opposed to the one side part supported and fixed on the back side of the game board 30 via the opening / closing mechanism 410, The rectangular projection 851 is formed. As shown in FIG. 25, the rectangular protrusion 851 protrudes rightward from the right and left edge portions of the outer case 70 and the inner case 85, respectively, by protruding pieces 851R and 851F having vertically long rectangular shapes. The inner case 85 is fitted to the outer case 70 and the protruding pieces 851R and 851F are superposed. Both projecting pieces 851R and 851F are respectively provided with screw holes 852R and 852F penetrating in the thickness direction at two upper and lower points, and screws (not shown) are screwed into these screw holes 852R and 852F. Thus, both the projecting pieces 851R and 851F are fastened and fixed.

  An outer connecting portion 72 is provided above and below the protruding piece 851R of the outer case 70, and an inner connecting portion 88 is provided above and below the protruding piece 851F of the inner case 85, respectively. The structure of the outer connecting portion 72 is substantially the same as the structure of the second pedestal sealing portion 432 of the connecting pedestal member 430 described above, and a bottomed screwing recess is formed on the rib connected to the right edge portion of the outer case 70. The protrusion which has is integrally molded, and the bottom face of the rib and the bottom face of the bottomed portion are flush with each other. The inner connecting portion 88 is formed integrally with the right edge portion of the inner case 85 and has a cylindrical structure in which a screw groove is formed. The outer connecting portion 72 and the inner connecting portion 88 are connected and fixed by fastening with screws.

  In addition, as a screw which fastens and fixes both the protruding pieces 851R and 851F of the outer case 70 and the inner case 85 and the outer and inner connecting portions 72 and 88, a metal screw may be used. For example, a resinous screw made of a high-functional resin (engineering plastic) such as polycarbonate, polyamide, polyacetal, polyphenylene ether, or polybutylene terephthalate having high strength or heat resistance may be used.

  As shown in FIG. 26, a seal 601 is affixed to the rectangular projection 851 of the first substrate case 201A, thereby sealing the right edge portion of the first substrate case 201A. The seal 601 is attached so as to straddle both the protruding pieces 851R and 851F of the outer case 70 and the inner case 85 in a state where the seal 601 is bent so as to have a U-shaped cross section.

  As shown in FIGS. 28 and 29, the seal 601 has a rectangular planar shape that can cover almost the entire three surfaces except the upper and lower surfaces of the rectangular projection 851 of the first substrate case 201A in a folded state. 27, the base material layer 602, the adhesive material layer 603, and the release paper 604 are laminated, and the IC tag unit 605 is disposed on the adhesive material layer 603.

  The base material layer 602 is made of a resin film such as a polyester film, and has an appropriate brittleness that is partially broken by the stress accompanying the force to peel off the seal 601, and dissolves in the adhesive constituting the adhesive material layer 603. It is discolored by the heat | fever (for example, 50 degreeC or more) of the temperature (for example, 50 degreeC or more) in which the adhesive force of an organic solvent, such as toluene, which has property, or an adhesive layer falls. Accordingly, when the solvent 601 is applied or heat is applied to illegally peel off the seal 601 from the rectangular protrusion 851 of the first substrate case 201A, the base material layer 602 is discolored and remains a fraudulent trace. It is like that.

  The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 603 has such an adhesive force that it is peeled off from the base material layer 602 when it is peeled off after being applied. Therefore, when the seal 601 is peeled off, it is difficult to apply it again, and a part of the pressure-sensitive adhesive layer 603 remains on the adherend side. Thereby, when the seal 601 is illegally peeled off, a trace can be left.

  The IC tag unit 605 includes an IC chip 605a and an antenna 605b, and the IC chip 605a is disposed near the center of the long antenna 605b extending in a strip shape. The IC chip 605a is formed as an integrated circuit and has a control unit and a memory area. ID information as identification data is stored in the memory area. The antenna 605b is formed of a thin metal layer such as aluminum, and the thickness thereof is thinner than that of the IC chip 605a. The antenna 605b is manufactured as an antenna pattern so that the resonance frequency is a constant frequency such as 2.45 GHz.

  The ID information stored in the memory area of the IC chip 605a is configured to be called by the control unit and transmitted from the antenna 605b, and the ID information transmitted from the antenna 605b is formed as a reader / writer. Can be received and read. Specifically, a call is made from the scanner with a weak radio wave having the frequency, and an induction electromagnetic field is formed by the radio wave. When the scanner is brought close to the antenna 605b to such an extent that the antenna 605b is located in the induction electromagnetic field, an electromotive force is generated in the antenna 605b by electromagnetic induction. In the IC chip 605a, using this electromotive force as a power source, the ID information stored in the memory area is called by the control unit and transmitted from the antenna 605b, and the ID information thus transmitted can be received and read by the scanner. It can be done.

  As shown in FIG. 29, the IC tag unit 605 (antenna 605b) has a diagonal corner side from one corner side of the base material layer 602 to the base material layer 602 on which the adhesive layer 603 is formed. It is arrange | positioned diagonally over. Specifically, the antenna 605 b is not on the diagonal line of the base material layer 602, and the longitudinal direction of the antenna 605 b intersects with both diagonal lines of the base material layer 602. In this case, the longitudinal direction of the long antenna 605 b intersects with all the side directions of the base material layer 602. The antenna 605b also straddles both the projecting pieces 851R and 851F as the seal 601 is applied across both the projecting pieces 851R and 851F constituting the rectangular projecting portion 851.

  In addition, a large number of antenna cuts 606 are formed in the seal 601 so as to be juxtaposed at equal intervals along the longitudinal direction of the antenna 605b. The antenna cut 606 is a straight line extending in a direction substantially orthogonal to the longitudinal direction of the antenna 605b, and penetrates from the surface side of the base material layer 603 to the back side of the adhesive layer 603 (FIG. 28). (The antenna cut 606 is not shown). Incidentally, the direction in which the antenna cut 606 extends is a direction substantially orthogonal to the longitudinal direction of the antenna 605 b, and thus intersects all the side directions of the base material layer 603. Further, the antenna cut 606 is configured to be slightly hung on the antenna 605b. In this case, since the antenna 605b is not divided by the antenna cut 606, there is no adverse effect on the transmission of the ID information. Also, the antenna cut 606 located on one side of the antenna 605b and the antenna cut 606 located on the other side are offset so that the antenna cut 606 does not line up in a straight line across the antenna 605b. . Specifically, the antenna cuts 606 located on one side of the antenna 605b and the antenna cuts 606 located on the other side are formed alternately along the longitudinal direction of the antenna 605b.

  When the seal 601 is to be peeled from the rectangular protrusion 851 of the first substrate case 201A, in order not to damage the seal 601 as much as possible, the stress accompanying the peeling force is applied to the corner of the base material layer 603. On the other hand, it is necessary to peel in the direction along the short side of the seal 601 so that it does not concentrate locally or concentrate on the bent portion of the seal 601, but this direction intersects the extending direction of the antenna 605b. Direction. Therefore, the stress accompanying the peeling force concentrates on the end of the antenna cut 606 located around the antenna 605b, and the base layer 603 is broken due to tearing starting from the antenna cut 606. Accordingly, the antenna 605b is divided. When the antenna 605b is divided, the ID information is not transmitted from the antenna 605b, so that the ID information cannot be read by the scanner. Therefore, the seal 601 is peeled off from the rectangular protrusion 851 of the first substrate case 201A as cleanly as possible, the first substrate case 201A is opened, and the control substrate 80 is tampered with, and then the first substrate case 201A is sealed. Even if the sticker 601 is pasted so as to be restored to the original state again, the illegal act can be easily found.

  Corner cuts 607 penetrating from the front surface side of the base material layer 603 to the back surface side of the adhesive layer 603 are formed at the four corners of the seal 601. Specifically, the corner cut 607 is formed in an L shape so as to be along the corner inside the corner of the seal 601. Therefore, even if the seal 601 is not peeled off in the direction along one side but is peeled off from the corner side (that is, obliquely with respect to the side of the seal 601), the seal 601 is broken from the corner notch 607. It becomes. Thereby, the trace of cheating can be left.

  As shown in FIG. 28, a large number of outer edge notches 608 are formed on the outer edge of the seal 601 from the outer end portion toward the inner side. These outer edge notches 608 are V-shaped with an acute angle that opens from the inside toward the outside, and are formed at equal intervals along the outer periphery of the seal 601. Therefore, when the seal 601 is peeled off from the rectangular protrusion 851 of the first substrate case 201A, the stress accompanying the peeling force concentrates on the inner end of the outer edge notch 608 and breaks the seal 601. Thereby, it is possible to leave a trace that the seal 601 has been peeled off, and it is possible to easily find out that an illegal act has been performed on the control board 80.

  However, in the configuration in which the outer edge notch 608 is formed as described above, if the seal 601 is peeled from the entire side of the seal 601 along the direction orthogonal to the side, the seal 601 is unlikely to break. That is, when the seal 601 is peeled off from the corner, or when the gap between adjacent outer edge cuts 608 on the outer edge of the seal 601 is picked and peeled off, stress due to the peeling force is concentrated on the inner end of the few outer edge cuts 608. Whereas the seal 601 is likely to be broken through the outer edge notch 608, when peeling from the entire side of the rectangular seal 601 along the direction perpendicular to the side, the stress associated with the peeling force causes many outer edges. Since it is dispersed at the inner end of the notch 608, the seal 601 is hardly broken via the outer edge notch 608. Therefore, when the seal 601 is peeled off by the latter method, there is a case where no imprint is left in the outer edge notch 608. However, as described above, the antenna 605b is disposed obliquely so as to extend from one corner side of the seal 601 to the diagonal corner side thereof, so that it is perpendicular to the side from the entire one side of the seal 601. Even if the seal 601 is peeled off along the direction of the antenna 605b, the antenna 605b is divided. Thereby, fraudulent acts can be easily found.

  As shown in FIG. 28, an ink application unit 609, an identification information unit 610, and a model information unit 611 are provided on the surface of the base material layer 603. The ink application unit 609 is applied with special ink that shows a pattern when irradiated with light of a specific wavelength such as ultraviolet rays. A plurality of numbers are described in the identification information portion 610, and the numbers described in the identification information portion 610 are different for each gaming machine. In this case, the numbers described in the identification information unit 610 are set in association with the ID information stored in the IC chip 605a. For example, when the ID information is registered as a number, the sum of the number of the ID information and the number described in the identification information unit 610 is the same in a plurality of gaming machines installed in a gaming hall or the like. Is set to In the model information section 611, a model name of the gaming machine, a manufacturer name of the gaming machine, and the like are described.

  Here, as shown in FIG. 26, the upper region R1 of the seal 601 in FIG. 28 is formed so as to be attached to the front side surface (surface opposite to the overlapping surface) of the protruding piece 851R of the outer case 70. It has become an area. Therefore, since the ink application unit 609 and the identification information unit 610 can be visually recognized from the position facing the first substrate case 201A, the confirmation operation of the ink application unit 609 and the identification information unit 610 can be easily performed. . Further, as shown in FIG. 26, the intermediate region R2 of the seal 601 in FIG. 28 is attached to the projecting end surfaces of both the projecting pieces 851R and 851F of the outer case 70 and the inner case 85 (that is, the projecting end surfaces of the rectangular projecting portions 851). It is a region formed with the intention of doing. Therefore, the contents described in the model information section 611 can be confirmed without removing the first substrate case 201A. Note that the lower region R3 is a region that is intended to be attached to the front side surface (the surface opposite to the overlapping surface) of the protruding piece 851F of the inner case 85. In addition, as described above, when the first board case 201A is attached to the back side of the game board 30, the locking piece 517 formed on the outer surface of the intermediate member 501 is elastically formed on the rectangular protrusion 851. For this reason, the intermediate region R2 and the lower region R3 or a part of the upper region R1 of the seal 601 attached from the protruding end surface of the rectangular protrusion 851 to the front side surface of the protrusion piece 851F of the inner case 85 Is in a state covered with the locking piece 517, but since the locking piece 517 can be easily removed, the ink application unit 609, the identification information unit 610 or the model information unit 611 is checked. It is also easy.

  By providing the ink application unit 609 and the identification information unit 610 as described above, when the first substrate case 201A is illegally replaced, it can be easily found that the replacement has been performed. . That is, even if the replaced fraudulent board case cannot be distinguished from the regular first board case 201A in appearance, it is exchanged by irradiating the ink application part 609 with specific light and confirming that no pattern appears. Can be found. Further, even if an IC tag unit is provided on the sticker of the fraudulent board case, the ID information is read by the scanner, and the information is confirmed by confirming the information and the information in the identification information section 610, so that the exchange is found. be able to.

  According to the above configuration, since the seal 601 having the IC tag unit 605 is pasted so as to straddle the outer case 70 and the inner case 85 that accommodate the control board 80, in order to open the first board case 201A. In this case, it is necessary to remove the seal 601 from the rectangular protrusion 851 and release the screw fixing of the rectangular protrusion 851. In this case, when the seal 601 is peeled from the corner, the stress accompanying the peeling force concentrates on the corner of the base material layer 603, and the base material layer 603 has moderate brittleness. The material layer 603 is greatly destroyed. In addition, since the outer edge of the seal 601 is formed with an outer edge notch 337 that opens in an acute V shape from the inner side toward the outer end, if the seal 601 is peeled off from the corner, the peeling force is increased. The accompanying stress concentrates on the inner end portion (portion pointed inward) of the outer edge notch 337, and the base material layer 603 is more easily broken. Further, since the seal 601 is bent and attached to the rectangular protrusion 851 of the first substrate case 201A in a substantially U-shape, when the seal 601 is peeled off from the corner, the stress accompanying the peeling force Concentrates on the bent portion, and similarly, the base material layer 603 is largely destroyed. In this case, the trace that the seal 601 has been illegally peeled off, that is, the fraud has been performed on the control board 80, remains clearly. Therefore, a person who intends to cheat on the control board 80 disperses the stress associated with the peeling force over one side of the base material layer 603 by peeling it from the whole side of the seal 601 along the direction orthogonal to the side. Therefore, the base member is prevented from being destroyed as much as possible. However, when the antenna 605b is arranged so that its longitudinal direction intersects with all the side directions of the seal 601, when the seal 601 is peeled off from the entire side, the direction intersecting with the longitudinal direction of the antenna 605b. Destruction occurs. And since the antenna 605b is elongate and the dimension of the direction which cross | intersects the longitudinal direction of the antenna 605b is short, the antenna 605b will be parted in the position where destruction occurred. In this case, since the manager of the game hall cannot check the ID information stored in the IC chip 605a by the scanner, it can easily and surely find out that fraud has been performed on the main board 270. .

  Further, as described above, the antenna 605b is arranged on one side of the base material layer 603 by arranging the antenna 605b so as to extend from one corner side of the base material layer 603 to the diagonal corner side thereof. The length dimension of the antenna 605b is ensured to be large as compared with the configuration provided along. Therefore, many opportunities can be provided for the antenna 605b to be separated when the seal 601 is peeled off.

  Further, by adopting a configuration in which the IC chip 605a is arranged at substantially the center in the longitudinal direction of the antenna 605b, the antenna 605b is arranged from one corner side of the seal 601 to the diagonal corner side as described above. In the configuration, the position of the IC chip 605 a is near the center of the seal 601. Therefore, it is possible to prevent the seal 601 from being easily peeled off due to the thickness of the IC chip 605a. That is, since the IC chip 605a has a predetermined thickness, a gap is generated between the periphery of the IC chip 605a in the seal 601 and the rectangular protrusion 851 of the first substrate case 201A. In this case, if the IC chip 605a is on the outer edge side of the seal 601, the seal 601 is easily peeled off by placing a finger in the gap between the outer edge and the rectangular protrusion 851 of the first substrate case 201A. On the other hand, since the position of the IC chip 605a is near the center of the seal 601, the gap between the outer edge of the seal 601 and the rectangular protrusion 851 of the first substrate case 201A is caused by the thickness of the IC chip 605a. There is no gap.

  In addition, by forming the antenna cut 606 around the antenna 605b in the base layer 603, the base layer 603 is broken from the end of the antenna cut 606 when the seal 601 is peeled off. As a result, the antenna 605b is also destroyed, and the antenna 605b is divided at that position. Therefore, the antenna 605b is easily divided, and the discovery when fraud is performed on the main board 270 can be more reliably performed. In particular, the antenna notch 606 is a linear notch extending in a direction intersecting the longitudinal direction of the antenna 605b and all the side directions of the base material layer 603, whereby the seal 601 is peeled in a direction along one side thereof. In this case, the stress accompanying the peeling force tends to concentrate on the antenna side end of the antenna cut 606. Thereby, the division of the antenna 605b when the seal 601 is peeled in the direction along the one side can be generated more reliably. Note that since the antenna cut 606 is formed up to a position reaching the antenna 605b, the antenna 605b is easily divided when the seal 601 is illegally peeled off. In addition, when the antenna cut 606 is formed so as not to be arranged in a straight line across the antenna 605b, for example, when there is no relation with fraud such as when the sticker 601 is attached at the time of manufacturing a gaming machine. It can be suppressed that the antenna cut 606 that is located with the antenna 605b interposed therebetween is connected and the antenna 605b is divided accordingly.

  Further, by forming L-shaped corner notches 607 penetrating from the surface side of the base material layer 603 to the back side of the adhesive layer 603 at the four corners of the seal 601, the seal 601 has its corners. When peeled off from the corner side, the stress accompanying the peeling force concentrates on the end of the corner cut 607 and breaks from the corner cut 607 to the seal 601. Therefore, a trace that fraud has been performed on the control board 80 remains on the seal 601, and it can be easily found that the fraud has been performed. Further, even if the seal 601 is peeled off in the direction along one side of the seal 601 to avoid the breakage of the seal 601 via the corner notch 607, the antenna 605b is divided as described above, so that fraud is easy. Can be found in.

  In addition, when the solvent which shows the solubility with respect to the adhesive which comprises the adhesive material layer 603 is applied to the seal | sticker 601, or the base material layer 603 is set as the structure discolored, the adhesive material layer 603 with a solvent is used. Even if a fraudulent act is performed on the control board 80 by removing the seal 601 without dividing the antenna 605b and separating the antenna 605b, it is possible to easily find out that the fraudulent act has been performed. Similarly, when heat of a predetermined temperature or higher is applied to the seal 601, the base material layer 603 is discolored so that the adhesive strength of the adhesive layer 603 is increased by applying heat of a predetermined temperature or higher. Even if a fraudulent act is performed on the control board 80 by removing the seal 601 without weakening the antenna 605b, it is possible to easily find out that the fraudulent act has been performed.

(Function)
As described above, in the pachinko machine 10, one side portion of the first board case 201A is supported and fixed to the back side of the game board 30 by an attachment structure including a connecting member made of metal, and one side of the first board case 201A. Since the other side portion facing the side portion is sealed by attaching a seal 601 configured to be able to transmit / receive radio waves to / from the outside, the seal can be received without hindering transmission / reception of radio waves. 601 can be operated reliably. One side portion (left side portion in the present embodiment) of the first substrate case 201A having a substantially horizontally long rectangular outer shape is a component constituting the mounting structure, and a support body 412 and a bracket 413, each of which is made of a steel plate. The connecting members such as the second engaging portion 433 are concentrated, and further, the sealing member 87 for connecting the outer sealing portion 71 and the inner sealing portion 86, and the connecting base member 430 are arranged in the first substrate case. A metal breaking screw 439 that is a fastener for coupling and sealing to 201A, a metal second engagement portion 433 that is an engagement member provided on the coupling base member 430, an intermediate member 501, and a ball assembly plate 460; Each of the housings 781 and 431 for housing the metal screw 519 and the breaking screw 522 and the sealing member 87 and the breaking screw 439, respectively, which are fasteners for sealing Partly that are arranged in a side portion (left portion) or near the casing 201A, in particular a environment in which the metal is present in a large amount. On the other hand, the other side portion (right side portion in the present embodiment) of the first substrate case 201A is a small size for fastening and fixing the protruding pieces 851R and 851F of the outer case 70 and the inner case 85 and the outer and inner connecting portions 72 and 88. This is an environment where only a small amount of metal is present. In this pachinko machine 10, the seal 601 is attached to the portion (right side portion) where the amount of metal present is very small, so the influence of the metal substantially affects the function of the seal 601. It has a configuration that does not reach. That is, the identification information stored in the IC chip 605a of the seal 601 can be reliably transmitted and received without being obstructed by the metal member. Thereby, the presence or absence of a fraudulent act can be detected correctly, and the pachinko machine 10 is highly reliable.

  Further, the mounting structure of the first board case 201A is a structure in which a bracket 413 made of metal (steel plate) is pivotally attached, and the first board case 201A is attached to the game board 30 via the bracket 413. Since it is attached to the back side so that it can be opened and closed, for example, the first substrate case 201A can be operated in an open state without being separated during inspection, so that the workability is improved. In this way, the metal member is unevenly distributed in one side portion (left side portion) of the first substrate case 201A, and the influence of the metal is great, so the other side facing this one side portion. The effect by having the structure which affixes the seal | sticker 601 to a part (right side part) and avoids the influence by a metal is also so much.

  Furthermore, if a resin screw is used as a screw for fastening and fixing the projecting pieces 851R and 851F of the outer case 70 and the inner case 85 and the outer and inner connecting portions 72 and 88, the first substrate to which the seal 601 is attached. Metal can be more thoroughly removed from the other side (right side) of the case 201A.

  Further, protrusions 851R and 851F are respectively formed on the edge portions of the outer case 70 and the inner case 85 of the first substrate case 201A, and the protrusions 851 are configured by superimposing the protrusion pieces 851R and 851F. Since the edge portion of the first substrate case 201A is sealed by applying the seal 601 to the protruding portion 851, the seal 601 can be easily and reliably applied, and the workability is good and the reliability is high. It has a sealed structure. That is, by superposing the plate-like projecting pieces 851R and 851F to form the projecting portion 851, the projecting portion 851 is made thinner than the first substrate case 201A (specifically, less than half). Thus, the seal 601 can be more easily applied and can be applied more firmly.

  Further, since the seal 601 is affixed to the protrusion 851 of the first substrate case 201A, the affixing position of the seal 601 is located on the outer side of the back side of the gaming machine 30, and the seal 601 at the factory is The reading confirmation work can be performed in a completed state of the gaming machine. In addition, since the sticking position of the seal 601 protrudes from the housing portion of the control board 80 and is secured as a separate area, the control board 80 is not hidden by the seal 601, and therefore whether the control board 80 is illegal or not is confirmed. When visually confirming, the seal 601 does not become an obstacle.

(Modification)
FIG. 30 is a diagram illustrating an example in which the first substrate case is configured to be mounted by another mounting structure. In the example shown in the figure, the lower part of the first board case 271A is supported and fixed to the back side of the game board 30 by an attachment structure using a rotation operation type fixing tool 277 made of metal. ing. The fixing tool 277 has a thumbscrew-shaped head and can be manually rotated, and is slightly above the lower end edge on the front surface (side surface of the game board 30) of the first board case 271A. Arranged so as to protrude forward (toward the game board 30 side) at two locations on the left and right sides. In the mounting base 251 to which the first substrate case 271A is attached, horizontally long through holes 256 are formed in two places on the left and right sides corresponding to the positions where the fixtures 277 are arranged. The first substrate case 271A is mounted on the mounting base 251 so that the fixing tool 277 is inserted through the through hole 256, and in this state, the fixing tool 277 is rotated by 90 ° and locked. . On the other hand, the upper part facing the lower part of the first substrate case 271A is sealed by applying a seal 612. The outer shape and dimensions of the seal 612 are slightly changed in accordance with the installation location, but the other configurations including the IC tag unit are all the same as the seal 601 shown in the above embodiment. The seal 612 is attached so as to straddle the outer case 73 and the inner case 89 at the center of the upper edge portion of the first substrate case 271A.

  In this embodiment, the lower part, that is, one side part of the first substrate case 271A is supported and fixed by the fixture 277, which is a connecting member made of metal, but the upper part, that is, the other side that faces this lower part. Since the seal 612 is affixed to the portion, the influence of the metal does not substantially affect the function of the seal 612, and the identification information stored in the IC chip of the seal 612 is reliably transmitted and received without being obstructed by the metal. Can be done.

  FIG. 31 is a schematic diagram showing another example of a position where an attachment structure including a connecting member made of metal is provided and a position sealed by applying a seal. In the example shown in the figure, one side portion (left side portion) D1 of the substrate case 211 is supported and fixed by a mounting structure (not shown) including a connecting member made of metal, and a seal 613 is provided on the other side portion (right side portion) D2. It is affixed. The sticking position of the seal 613 is in the vicinity of the right end on the upper end edge located in the other side portion (right side portion) D2 of the substrate case 211. As described above, the support fixing position of the substrate case or the sticking position of the seal may be at any corner of the substrate case in addition to the central portion of any edge of the substrate case.

  FIG. 32 is a diagram illustrating another example of the rectangular protrusion of the substrate case. In the example shown in the figure, similarly to the above-described embodiment, a rectangular protrusion 853 is formed on the right edge portion of the substrate case 212, and screw holes 854H and 854L are formed at two upper and lower portions of the rectangular protrusion 853. Although provided respectively, these upper and lower screw holes 854H and 854L are adapted to be screwed in from opposite directions. That is, in the upper screw hole 854H, a recess for accommodating the screw head is formed on the outer surface of the rectangular projection 853 (the surface facing the back of the pachinko machine 10), and the screw is inserted from the outer side of the rectangular projection 853. On the other hand, in the lower screw hole 854L, a recess for accommodating the screw head is formed on the inner surface of the rectangular protrusion 853 (the surface facing the front of the pachinko machine 10), A screw is screwed from the inside of the rectangular protrusion 853. Further, the seal 614 is affixed to the rectangular protrusion 853 in the same manner as in the above embodiment. At this time, one end of the antenna 615 straddles the head receiving recess of the upper screw hole 854H, and the antenna 615 The other end portion straddles the head receiving recess of the lower screw hole 854L. According to this configuration, in any of the upper and lower screw holes 854H and 854L, in order to expose the screw head, it is necessary to peel off the seal 614 at the portion where the antenna 615 is disposed. The antenna 615 can be divided, and therefore, when the screw is illegally removed from the rectangular protrusion 853, the trace can be more reliably left.

  Furthermore, in this embodiment, an upper flange 853H and a lower flange 853L having a lateral dimension and a longitudinal dimension slightly larger than the transverse section of the rectangular projection 853 are formed at the upper end and the lower end of the rectangular projection 853, respectively. ing. In this configuration, both short sides of the seal 614 are attached along the upper flange 853H and the lower flange 853L, and both long sides of the seal 614 are attached along the right end surface 212E of the substrate case 212. That is, the peripheral edge of the seal 614 is pasted so as to be surrounded by the upper and lower flanges 853H and 853L and the right end surface 212E of the substrate case 212. Thus, when the seal 614 is attached to the rectangular protrusion 853, the upper and lower flanges 853H and 853L and the right end surface 212E of the substrate case 212 are positioned as a guide structure that can guide the periphery of the seal 614 to the application position. Becomes easier and the workability is improved. Further, in the state where the seal 614 is affixed, the peripheral edge thereof is surrounded by the upper and lower flanges 853H and 853L and the right end surface 212E of the substrate case 212, which makes it more difficult to peel off. It is made surely.

  33 and 34 show an example in which the seal is covered with a cover member. In the example shown in the figure, a substantially rectangular parallelepiped having a shape substantially corresponding to the outer shape of the rectangular protrusion 855 of the substrate case 213 and having a lumen portion 616a having a slightly larger dimension (volume) than the rectangular protrusion 855. A cover member 616 having a shape is detachably attached to the rectangular protrusion 855. The cover member 616 is opened only at one end surface to form an opening 616b, and engaging pieces 616H and 616L are formed on the upper surface and the lower surface, respectively. As shown in FIG. 34, the engagement piece 616L of the lower surface portion is perpendicular to the inner side of the slightly lower portion of the edge on the opening 616b side (the slightly upward portion in FIG. 34) on the lower surface portion of the cover member 616. By forming notches so as to form two parallel grooves extending to each other, a portion between these notches is formed into a flexible piece that can be easily elastically deformed up and down. ing. An engagement claw that protrudes inward (upward) is formed at the tip of the engagement piece 616L. On the other hand, as shown in FIG. 33, a similar engagement piece 616H is formed on the upper surface portion of the cover member 616 so as to be symmetrical with the engagement piece 616L of the lower surface portion.

  Engagement protrusions 855H and 855L are formed on the upper and lower surfaces of the rectangular protrusion 855 of the substrate case 213 corresponding to the upper and lower engagement pieces 616H and 616L of the cover member 616, respectively. That is, as shown in FIG. 34, in the rectangular protrusion 855 of the substrate case 213, the engagement protrusion 855L is formed on the lower surface of the protrusion piece 855R protruding from the outer case 74 of the substrate case 213 so as to protrude downward. Has been. On the other hand, a similar engagement protrusion 855H is formed on the upper surface of the protrusion piece 855R so as to be symmetrical with the engagement protrusion 855L of the lower surface, as shown in FIG.

  The cover member 616 is fitted into the rectangular protrusion 855 so that the rectangular protrusion 855 of the substrate case 213 is inserted into the lumen 616a from the opening 616b. When the cover member 616 is completely fitted to the rectangular protrusion 855 (up to the root of the rectangular protrusion 855), the upper and lower engagement pieces 616H and 616L are moved to the upper and lower engagement protrusions 855H and 855L. The cover members 616 are locked in a state of covering the rectangular protrusions 855 by elastically engaging with each other.

  The cover member 616 is obtained by molding a light-transmitting resin, and is attached to the rectangular protrusion 855 in a state where the cover member 616 is fitted to the rectangular protrusion 855. The situation of 617, the symbol information described in the identification information section, etc. can be visually recognized or read from the outside. Further, the ID information of the seal 617 can be received and read by bringing the scanner close from the outside while the cover member 616 is fitted. At this time, the cover member 616 is held at the mounting position by the upper and lower engaging pieces 616H and 616L elastically engaging with the upper and lower engaging protrusions 855H and 855L as described above. Can be removed easily, so even if it is difficult to view the seal 617 or to read the ID information by the scanner for some reason, the cover member 616 is removed and the seal 617 is exposed so that it can be directly viewed. And the reading of ID information can be performed, and the cover member 616 can be easily attached again after the operation.

  Further, the cover member 616 has sufficient mechanical strength to protect the seal 617 from an external impact and has sufficient heat resistance.

  Further, as described above, the lumen portion 616a of the cover member 616 has a slightly larger size (volume) than the rectangular projection portion 855, and therefore, when the cover member 616 is fitted, the seal 617 and the lumen portion 616a. A gap is formed between them, and the air in the gap becomes a heat insulating layer, so that the seal 617 is more reliably protected from external heat.

According to the configuration in which the seal 617 is covered with the cover member 616 as described above, the seal 617 can be effectively protected against external impact and heat.
Game machines are often subjected to mechanical impacts, such as when a game ball collides with the back of the game machine or is rubbed during component inspection after being installed in a hall, and the IC tag unit of the seal 617 is affected by this impact. May be damaged. In addition, when a gaming machine is shipped from the factory, a heat-shrinkable sheet is wound around to protect the gaming machine. However, the heat-shrinkable sheet is heated at a high temperature in order to adhere to the gaming machine. Therefore, when the environment of the seal 617 reaches a temperature higher than the guaranteed temperature of the IC tag unit, the IC tag unit may be damaged.
On the other hand, the seal 617 is effectively protected by covering with the cover member 616 as described above, and the IC tag unit is damaged by an impact or heat, making it impossible to read the ID information. Thus, the reliability of the gaming machine can be further improved.

  The cover member 616 may be attached at an arbitrary stage depending on the usage situation of the gaming machine. For example, the cover member 616 is attached immediately after sticking the seal 617 to the rectangular protrusion 855 of the board case 213, and is continuously attached after the game machine is installed in the hall, and only when inspection is necessary. Examples of usage include temporarily removing or attaching a cover member 616 by selecting a necessary stage among several stages such as when the gaming machine is transported or after the hall is installed.

  In addition to being configured to be separable as described above, the cover member may be configured to be supported by a gaming machine component other than the board case, for example, as shown in FIG. In the example shown in the figure, a cover member 618 is pivotally supported by a vertical axis on the back side (substrate case 214 side) at the right end of the intermediate member 502 as indicated by an arrow A2, With the substrate case 214 attached to the back surface side of the intermediate member 502, the cover member 618 can be attached to and detached from the rectangular protrusion 856 of the substrate case 214 by rotating as described above. When the cover member 618 is fitted to the rectangular projection 856, the cover member 618 is locked by the same engagement structure (not shown).

  Furthermore, for example, as shown in FIGS. 36 to 38, the cover member may be detachably supported by a gaming machine component other than the board case. 36 is a rear perspective view showing an example in which the cover member is detachably supported by the intermediate member (a perspective view seen from the game board side), FIG. 37 is a rear view of FIG. 36, and FIG. 38 is a bottom view of FIG. is there. In the example shown in the figure, the cover member 619 is similar to the shape of the outer surface (surface facing the back of the gaming machine) of the rectangular protrusion (not shown) of the substrate case 215, and the rectangular protrusion It is formed into a vertically long rectangle having a size slightly larger than the outer side surface of the portion, and a shaft 619A is formed along the long edge, and from the central portion of the upper and lower short edges to the inner surface side of the cover member 619, respectively. An engaging claw 619C extending vertically is formed. On the other hand, the intermediate member 503 is formed with a pivot portion 503H for supporting the intermediate member 503 on the back surface of the game board on one side end surface, and the back surface side on the end surface (left end surface in the figure) on which the pivot portion 503H is formed. Bearing portions 503A are formed vertically along the edge (the edge on the board case 215 side edge) at intervals corresponding to the length of the shaft 619A of the cover member 619, and from the middle position between these bearing portions 503A, the game A protrusion 503P that extends horizontally toward the front of the machine is formed, and the shaft 619A of the cover member 619 is located at the rear end of the upper and lower bearing portions 503A and the protrusion 503P (the end that extends toward the rear of the gaming machine). In this state, the upper and lower ends of the shaft 619A are supported by the upper and lower bearing portions 503A from the back (the back of the gaming machine), respectively. It is adapted to be supported from the front (the front of the gaming machine) by the rear end of the central portion ridge 530p. As a result, the cover member 619 is pivotally supported about the vertical axis 619A as indicated by an arrow A3 in the drawing. When the cover member 619 is rotated to the substrate case 215 side with the cover member 619 being fitted to the intermediate member 503 in this way, the engagement claw 619C is elastically locked to the rectangular protrusion of the substrate case 215, and The rectangular protrusion is held in a state covered with the cover member 619.

  According to the above configuration, the cover member 619 can be attached to and detached from the intermediate member 503 at an arbitrary time. For example, after the cover member 619 is attached to the intermediate member 503 in advance and the substrate case 215 is attached to the intermediate member 503, The rectangular protrusion may be covered with a cover member 619, and after the game machine is transported, the cover member 619 may be removed from the game machine and then attached and detached again at an arbitrary time.

  In addition to the structure in which the cover member is held by the intermediate members 502 and 503 as described above, for example, an intermediate member in a gaming machine such as a case where the cover member is held by a collective plate when the intermediate member is not disposed. It is good also as a structure hold | maintained in appropriate positions other than.

  According to the above configuration, since the cover members 618 and 619 are held by the gaming machine components (intermediate members 502 and 503), there is an advantage in terms of work that the cover members 618 and 619 need not be handled separately. However, since the cover member 618 cannot be attached to and detached from the substrate cases 214 and 215 in a state where the substrate cases 214 and 215 are not attached to the intermediate members 502 and 503, from the viewpoint of protecting the seal at an arbitrary time point, It is desirable that the cover member is configured to be separable as in the example.

  The present invention can be implemented as appropriate as long as it is a gaming machine provided with a substrate case, and its application range is wide.
