  The glass plate holding frame 4 is provided with a circular see-through window 5 through which a game area of a game board 40 described later can be substantially seen through, and a glass plate is mounted from the back surface of the circular see-through window 5. Further, the glass plate holding frame 4 is provided with a decorative LED 7 on the upper portion thereof along the outer periphery of the circular see-through window 5 and decorative fluorescent lamps 6a and 6b on the left and right sides thereof. The decorative LED 7 and the decorative fluorescent lamps 6a and 6b are lit or flashed in accordance with the gaming state, notifying the player of the occurrence or continuation of a special gaming state and increasing the gaming atmosphere. is there. In addition, a ball out LED 8 for notifying that there is a shortage of premium balls to be paid out, or a predetermined number of premium balls are paid out to the upper part of the glass plate holding frame 4 based on the occurrence of winning balls. Is provided, and speakers 10a and 10b that generate sound effects according to the progress of the game are provided on the upper left and right of the glass plate holding frame 4. Of the above-described configurations, the decorative LED 7, the ball-out LED 8, and the payout LED 9 are configured such that a plurality of LEDs are mounted on the printed wiring board. By comprising with a board | substrate, the thermal radiation effect of the heat | fever generated from LED can be heightened.

  Next, the structure of the upper plate 12 that can be freely opened and closed at the lower part of the glass plate holding frame 4 will be described. The upper plate 12 combines a plurality of synthetic resin members on the surface of the upper plate opening and closing plate 11 made of synthetic resin. It is comprised by adhering the plate member. The upper plate opening / closing plate 11 is provided with a doffing operation lever 16 at the upper end on the open side. The ball removal operation lever 16 is provided so as to be movable in the left-right direction, and moves the ball stored in the upper plate 12 in one direction against the urging force of a spring (not shown), thereby allowing the upper plate opening / closing plate 11 to move. A ball-out path (not shown) formed on the back surface of the bottom plate 18 is caused to flow down and guided to the lower plate 18. Further, the upper plate 12 has a piezoelectric buzzer 17 incorporated therein. The piezoelectric buzzer 17 is called a beep when a gaming ball lending abnormality occurs (for example, a continuous sound of a beep, a beep or a beep) or when a gaming ball is lended (for example, every time a gaming ball equivalent to 100 yen is paid out). Sound) is generated to notify that effect.

  The above-described upper plate 12 will be described in more detail. The upper plate 12 is stored and aligned so as to communicate a prize ball outlet 14 formed on the upstream side thereof and a hitting ball supply port 15 formed on the downstream side thereof. A path 13 is formed, and an upper plate ball detector (not shown) is provided on the bottom bottom surface in the middle of the storage alignment path 13. The upper plate ball detector detects a hit ball remaining on the upper plate 12.

The automatic ball lending display LED is turned on when the automatic motor is selected and set.

  Thus, when a big hit gaming state occurs in the game content of the gaming board 40 described later, there is a chance to win a large number of winning balls in a short time. In this way, a very big chance for the player in the big hit gaming state may occur when there is almost no remaining ball on the upper plate 12, and in such a case, the hit ball is continuously fired to change the hit ball. Although it is necessary to win in the specific winning area of the winning ball apparatus 42, the hit ball does not remain on the upper plate 12, so the ball lending switch must be operated and the game ball must be borrowed. However, since it takes some time for the game ball to be paid out after the ball lending switch is operated, and to reach the specific winning area of the variable winning ball device 42 after that ball is fired, Although there is an inconvenience that an advantageous chance (establishment of continuation right) is missed, in this embodiment, if the automatic ball lending switch is set to the automatic mode, the upper plate ball detector does not have a hit ball. Since the game balls are automatically paid out to the upper plate 12 at the time when is detected, the above-mentioned inconvenience does not occur. If the above-described control is not performed for the upper plate 12, the upper plate ball detector and the automatic ball lending switch may be omitted.

On the other hand, in the vicinity of the flange piece 112 erected in the vicinity of the two corners on the other side in the width direction, a through hole 114 that penetrates the mounting piece 122 described later is formed. In addition, a notch 115 is formed at a substantially central portion on one side in the longitudinal direction. The notch 115 is a notch for releasing interference with an engagement protrusion 154 described later in a state where the circuit board box 62 is attached to the mounting base 150.

  The main body frame 116 has an opening 117 on the lower surface, and has a shape having a side wall on the entire outer periphery thereof. Engagement pieces 118 having a L-shaped cross section are formed on both sides in the width direction on the inner peripheral edge of the opening 117 with a predetermined length, and a locking hole is formed on one side in the longitudinal direction of the inner peripheral edge. A locking piece 119 formed with 120 is formed. In addition, a plurality of elliptical reduction holes 121 are formed in the remaining lower surface region other than the opening 117. Attachment pieces 122 having attachment holes 123 are formed at both ends on one side in the width direction in the lower surface region, and engagement pieces 124 having engagement protrusions 125 are provided at both ends on the other side in the width direction in the lower surface region. Is formed. The engaging piece 118 is bent slightly downward at the tip so that the engaging piece 118 can be easily engaged with the engaging rail 151 on the mounting base 150 side when attached to the mounting base 150 described in detail later.

  On the other hand, a plurality of heat radiating holes 128 are formed in one side wall of the main body frame 116 in the width direction. On both side walls in the width direction of the main body frame 116, reinforcing pieces 129 are extended at both ends in the longitudinal direction. The reinforcing piece 129 is bent inward from the extended portion to press both side walls in the longitudinal direction of the main body frame 116 from the inside, thereby improving the strength of the main body frame 116. Moreover, since the gap between the side walls is closed, it is impossible to illegally attempt to remodel by widening the side walls. Such a reinforcing piece is not limited to the main body frame 116 and may be provided on the lid frame 93 side. A mounting piece 130 is provided on one side wall of the body frame 116 in the width direction. The attachment piece 130 is formed by bending the upper end portions at both ends of one side wall inward. The attachment pieces 130 are provided with attachment holes 131 to 134 corresponding to the attachment holes 86a to 86d on the lid 80 side, respectively, and one-way screws 140 for equipment are respectively provided in the vicinity of the attachment holes 132 to 134. Equipment holes 135 to 137 to be equipped in the inserted state are formed. Engaging claws 138 that engage with the locking holes 99 on the lid 80 side are formed at one end of both side walls in the longitudinal direction of the main body frame 116.

  Thus, the lid 80 and the box body 110 described above are configured as an assembly (circuit board box 62) in which the circuit board 61 is accommodated by the following assembly. First, the circuit board 61 and the bottom plate 111 are mounted on the main body frame 116 so as to overlap each other. Then, the engaging protrusion 125 of the engaging piece 124 is inserted into the engaging hole 78 of the circuit board 61, while the fastening hole 77 of the circuit board 61 is screwed to the attaching hole 123 of the attaching piece 122 to fix the bottom plate 111. Then, the circuit board 61 is fixed to the main body frame 116. Further, in such mounting and fixing of the circuit board 61, when the hole positions of the stop hole 77 and the mounting hole 123 are aligned, the circuit board 61 is slightly displaced, so that the engaging protrusion 125 and the engaging hole 78 are engaged. The one side in the width direction of the circuit board 61 that is not screwed is also fixed.

  Next, the lid body 80 is put on the box body 110 whose upper surface is open. At this time, the engaging claw 138 on the box body 110 side is locked in the locking hole 99 on the lid 80 side by insertion in the D direction shown in FIGS. 4 and 6, and one side in the width direction of the circuit board box 62. Is attached (see FIG. 10A). Further, the partition wall 98 of the lid 80 is in a state where the electronic component mounting area 74 and the connector mounting area 76 of the circuit board 61 are partitioned into the inside and outside of the lid frame 93. Thereby, it is possible to attach and remove the wiring to the connector 75 without removing the lid 80. 4 and 6, the mounting hole 86 a of the mounting piece 83 a is fastened to the mounting hole 131 of the main body frame 116 with a one-way screw (screw) 140 and the other side in the width direction of the circuit board box 62. (See FIGS. 8A and 10B), and the screw 140 stopper portion is sealed with a rectangular hologram seal 105. Further, the side wall of the lid 80 and the side wall of the box body 110 are sealed with a rectangular hologram seal 104. As a result, an assembly (circuit board box 62) in which the circuit board 61 is housed in a sealed state in the internal space between the lid body 80 and the box body 110 is configured. The screw 140 between the lid body 80 and the box body 110 is fixed only on the other side in the width direction of the circuit board box 62, but one side in the width direction of the circuit board box 62 is in a screw 140 stopped state (sealing). Unless the state is released, the engagement (engagement between the engaging claw 138 and the locking hole 99) cannot be released.

  Further, in the assembled state of the lid 80 and the box main body 110, the overlapping wall 96 of the lid 80 is attached so as to cover the side wall of the box main body 110 from the outside. For this reason, even if it is going to perform fraud from parts other than a sticking location and an engagement location, this can be prevented. Further, the one-way screw 140 inserted into each of the equipment holes 135 to 137 is accommodated in the box 62 without being detached from the equipment holes 135 to 137 by being attached so that the lid body 80 covers from above. Yes. That is, in such a storage state, as shown in FIG. 7 and FIG. 8B, the upper wall surfaces in the vicinity of the attachment pieces 83b and 83c and the attachment hole 86d of the lid 80 individually project the one-way screw 140. Blocking. In addition, the installation method of the one-way screw 140 is not limited to the one described in the embodiment. For example, in the assembled state of the box 62, the head of the one-way screw 140 is completely pressed down by the lid 80 (mounting piece portion or the like), or the diameter of the one-way screw 140 and the diameter of the equipment holes 135 to 137 are approximately The same configuration may be used. In such a configuration, the mounted one-way screw 140 can be held back when the circuit board box 62 is closed.

  Here, the one-way screw 140 will be described. The one-way screw 140 is a special screw that rotates only in the screw tightening direction, and once tightened, it cannot be removed unless the screw is destroyed. Specifically, as shown in FIGS. 9A and 9B, a screw groove provided in the head 141 is composed of a contact surface portion 142, a concave portion 143, and a central hole portion 144. 9C and 9D, when the screw 140 is tightened with the special minus driver 145, the central shaft portion 146 of the driver 145 is inserted into the central hole portion 144, and the contact piece of the driver 145 from this state. The part 147 is brought into contact with the contact surface part 142 and the head 141 is rotated in one direction (clockwise direction in FIG. 9A) to tighten the screw 140. On the other hand, when the screw head 140 is rotated by the driver 145 in the other direction (counterclockwise direction in FIG. 9A) to remove the screw 140, the driver 145 enters the recess 143 and slips. The head 141 cannot be rotated and the screw 140 cannot be removed. It is possible to rotate the head 141 in one direction and tighten the screw 140 even with a normal flathead screwdriver. However, like the special flathead screwdriver 145, the central shaft portion 146 is connected to the central hole portion 144 of the one-way screw 140. The tightening operation can be easily performed by inserting and positioning with the one-way screw 140.

  Further, the screw (one-way screw 140) for assembling the lid body 80 and the box body 110 is configured to enter the outer wall surface of the lid frame 93 in a screwed state. For this reason, the hologram seal 105 that seals the screw 140 stop portion is affixed on a flat surface having no protrusions, so that the seal 105 can be prevented from being peeled off and damaged, and fraudulent acts on the seal 105 can be easily identified. Here, the hologram sticker will be briefly described. The hologram sticker includes a hologram layer, a light reflecting layer, and an adhesive layer, and the hologram pattern formed on the hologram layer is configured to be a counterfeit by making it difficult to counterfeit. This prevents the sticker from being replaced. In this hologram pattern, coherent light (laser light) incident on the surface of the hologram seal enters the light reflection layer through the embossed surface of the hologram layer, and is reflected from the light reflection layer to the outside of the hologram seal as hologram interference light. Is formed. Further, when the hologram sticker is peeled off, the hologram pattern does not return to its original shape even if it is applied again, so that the peeled trace remains.

  As described above, in the circuit board box 62, the screw 140 fixing portion between the lid 80 and the box body 110 is sealed with the hologram seal 105, and the side wall of the lid 80 and the side wall of the box body 110 are sealed with the hologram seal 104. By doing so, the covering state of the circuit board 61 is secured. In addition, an electromagnetic shielding effect can be achieved by the conductive plate 100 provided in the box 62. Further, the circuit board box 62 is formed by forming the upper plate 81 and the conductive plate 100 constituting the upper wall surface thereof, and the bottom plate 111 constituting the lower wall surface from a material having transparency, so that the mounting surface ( The upper surface) and the solder surface (lower surface) can be seen through from the outside. For this reason, when an unauthorized work (for example, an unauthorized work in which a jumper wiring is connected or an electronic component is mounted) is performed on the circuit board 61, the unauthorized work is immediately known.

  Next, a mounting base 150 for mounting the circuit board box 62 to the mechanism plate 50 will be described with reference to FIG. As shown in FIG. 3, the mounting base 150 is made of a rectangular plate made of synthetic resin (or metal), and a pair of engagement rails 151 having an inverted L-shaped cross section are arranged at a predetermined interval at the center of the substrate. It is laid down. The direction in which the engagement rail 151 is provided is the left-right direction along the long side portion of the mounting base 150. On each long side portion (front and rear end edges) of the mounting base 150, a guide piece 152 that is orthogonal to the substrate surface is projected. A release lever 153 that is elastically deformed is formed at the right end of the mounting base 150, and an engagement protrusion 154 that engages with the locking hole 120 on the box body 110 side protrudes from the base of the release lever 153. It is installed. Further, a stop hole 155 for screwing the mounting base 150 to a mounting boss (not shown) on the mechanism plate 50 side is formed in the board surface of the mounting base 150.

  Thus, the mounting base 150 is fixed to a predetermined portion on the mechanism plate 50 by being screwed to the mechanism plate 50 through the stop hole 155. When the circuit board box 62 is attached to the mounting base 150, the box 62 is slid from the left side of the mounting base 150. At this time, the engagement rail 151 on the mounting base 150 is in a state of being engaged with the engagement piece 118 on the box 62 side, and the guide piece 152 guides the sliding movement of the box 62. The release lever 153 on the mounting base 150 side is elastically deformed downward by such sliding movement of the box 62, and finally the locking hole 120 on the box 62 side engages with the engaging protrusion 154 on the mounting base 150 side. Then, the mounting of the box 62 is completed. On the other hand, when removing the circuit board box 62 from the mounting base 150, the release lever 153 is pushed downward to release the engagement between the locking hole 120 and the engagement protrusion 154, and the box 62 is slid to the left from this state. Can be removed easily. In other words, the circuit board box 62 is detachable from the mounting base 150 fixed to the mechanism plate 50 with screws.

  Next, a procedure for opening the circuit board box 62 described above for inspection of the circuit board 61 (inspecting whether the ROM is proper after delivery) and then restoring the closed state again will be described. First, in the closed state of the circuit board box 62, the hologram seals 104 and 105 are peeled off, and the connecting portions 84a and 85a are cut with a cutting tool such as a nipper, with the marking “1” as a mark. As a result, the attachment piece 83a is completely separated from the lid 80 and fixed to the box body 110 by the one-way screw 140, as shown in FIG. That is, the fixing (screw 140 stop) and engagement (engagement of the engagement claws 138) of the lid body 80 with respect to the box body 110 are all released, and the circuit board box 62 can be opened. Then, the lid 80 is removed from the box body 110 and the circuit board 61 is inspected. In addition, by removing the lid 80 (cutting the connecting portions 84a and 85a), the one-way screw 140 inserted into each of the equipment holes 135 to 137 can be taken out. Take out the one-way screw 140 for restoring the box 62. Thereafter, when closing the circuit board box 62, the lid 80 is put on the box body 110 with the engaging claws 138 engaged with the locking holes 99, and the one-way screw 140 taken out is engraved with “2”. The mark is screwed into the mounting hole 86b of the mounting piece 83b. Thereby, the attachment hole 86b of the attachment piece part 83b and the attachment hole 132 of the main body frame 116 corresponding to this are fastened together by the one-way screw 140. Then, a new hologram seal 105 is attached to the mounting portion 83b of the screw 140, and the side wall of the lid 80 and the side wall of the box body 110 are sealed with the hologram seal 104, whereby the circuit board box 62 is It is restored to the closed state again.

  Thereafter, when the circuit board box 62 is inspected again (the second inspection), the hologram seals 104 and 105 are peeled off, and the connecting portions 84b and 85b are cut using the marking “2” as a mark. As a result, the mounting piece 83b is separated from the lid 80 and the circuit board box 62 is opened. Thereafter, similarly, the engaging claw 138 is engaged with the locking hole 99, and the one-way screw 140 (one-way screw 140 of the equipment hole 136) taken out along with the cutting of each of the connecting portions 84b and 85b is engraved with “3”. Are screwed into the mounting holes 86c of the mounting piece 83c, and new hologram seals 104 and 105 are pasted. As a result, the circuit board box 62 is restored to the closed state again. Thereafter, when the circuit board box 62 is inspected (the third inspection), the hologram seals 104 and 105 are peeled off, and the connecting portions 84c and 85c are cut using the mark “3” as a mark. The part 83c is separated from the lid 80, and the circuit board box 62 is opened. Further, when the circuit board box 62 is restored, the engaging claw 138 is engaged with the locking hole 99 and the one-way screw 140 (one-way screw 140 of the equipment hole 137) taken out along with the cutting of the connecting portions 84c and 85c. Are screwed into the last remaining mounting hole 86d, and new hologram seals 104 and 105 are attached.

  By the way, in the closed state of the circuit board box 62 described above, unless the connecting portions 84a to 84c and 85a to 85c are cut to release the connection (fixed state) between the mounting pieces 83a to 83c and the upper plate 81, the box The engagement between the engaging claw 138 of the main body 110 and the locking hole 99 of the lid 80 cannot be released, and the circuit board box 62 cannot be opened. Therefore, when the connecting portions 84a to 84c and 85a to 85c are cut other than the inspection of the circuit board 61, it is possible to immediately and reliably determine that the fraud has been made to the circuit board 61 by this cutting. The crime prevention effect of the circuit board box 62 can be enhanced. Further, by providing the above-described engaging portions (the locking holes 99 and the engaging claws 138), the fixing positions of the box main body 110 and the lid body 80 can be minimized to the minimum without reducing the crime prevention property of the box 62. As a result, the assembly workability of the circuit board box 62 can be improved. Further, in the configuration of the circuit board box 62, even if the welding projection 82 of the upper plate 81 is cut off, the conductive plate 100 falls on the circuit board 61, so that the circuit board 61 is attempted to be crafted from the gap where the welding projection 82 is cut off. The conductive plate 100 prevents this. Further, when the hologram stickers 104 and 105 are peeled off, traces of the hologram stickers 104 and 105 remain firmly, so that it is immediately known that fraud has been performed.

  As described above, the circuit board box 62 according to the present embodiment includes the box body 110 and the lid body 80, and the locking holes 99 and the engaging claws 138 that are attached by engaging the box body 110 and the lid body 80. And an attachment piece 83a for attaching the box body 110 and the lid 80 in a fixed state by the one-way screw 140, and the engagement hole 99 and the engagement claw 138 are engaged unless the attachment state of the attachment piece 83a is released. It is characterized in that the combined state cannot be canceled. With this configuration, it is possible to minimize the fixing position of the box main body 110 and the lid 80 without reducing the crime prevention property of the box 62, and thus improve the workability of assembling the circuit board box 62. be able to. Further, with this configuration, the cost can be reduced by reducing the number of one-way screws 140 used as the fixing means.

  Further, the box main body is cut by the connecting portions 84a and 85a for separating the attachment piece 83a and releasing the fixed state between the box main body 110 and the lid body 80, and the one-way screw 140 in the cut state of the connecting portions 84a and 85a. 110 and the cover body 80 are again attached to the fixed state, and the connecting pieces 84b and 83c are separated from each other, and the connection part 84b is released to release the fixed state between the box body 110 and the cover body 80 by separating the mounting piece portions 83b and 83c. 84c, 85b, and 85c, the circuit board 61 can be inspected a plurality of times on the premise that the circuit board box 62 having a high crime prevention effect is restored again. Further, since the engaging claw 138 is made of a flat metal, it cannot be easily cut with a nipper or the like. Even when cut using a thread saw or the like, the cut portion has a flat plate shape, so that it is difficult to bond, and fraud can be easily determined. Further, since the box body 110 and the lid body 80 are configured to be attached with their side walls overlapped, it is possible to prevent fraud from being attempted from a portion other than the fixing location and the engagement location. it can.

  Moreover, since the mounting holes 86a to 86d for mounting the one-way screw 140 are provided in the mounting pieces 83a to 83c in the direction orthogonal to the surface for mounting the circuit board box 62 to the ball game machine 1, the circuit board box 62 after inspection is provided. Restoration work can be performed even more easily. Further, since the attachment piece portions 83a to 83c are formed along the outer wall surface of the circuit board box 62, the attachment piece portions 83a to 83c do not protrude from the outer wall surface of the box 62, and damage or the like can be prevented. Further, a plurality of the mounting piece portions 83b and 83c are provided, and connecting portions 84b, 84c, 85b, and 85c that release the fixing state between the box body 110 and the lid body 80 by separating the mounting piece portions 83b and 83c are provided. Since the circuit board 61 is provided, the circuit board 61 can be inspected a plurality of times (three times) and restored to the circuit board box 62 having a high crime prevention effect each time. Further, since the mounting piece portions 83a to 83c are provided on the lid body 80 and the box main body 110 is constituted by the metal main body frame 116, the strength of the circuit board box 62 can be improved and the box 62 can be deformed. And damage can be avoided.

  Further, since the circuit board box 62 is provided with a plurality of the one-way screws 140, it is not necessary to prepare a one-way screw for each restoration work after the inspection, and the restoration work of the circuit board box 62 is facilitated. In addition, since the outer wall surfaces of the attachment pieces 83a to 83d that fix the box body 110 and the lid 80 are flat and the hologram seal 105 is adhered to the outer wall surfaces, the circuit board box 62 Can be secured by the hologram seal 105. Furthermore, since the hologram seal 105 is affixed on a flat surface without protrusions, the seal 105 can be prevented from being peeled off and damaged, and fraudulent acts on the seal 105 can be easily identified.

  The above-described embodiment does not limit the present invention, and various modifications can be made within the scope of the present invention. For example, in the above embodiment, the attachment pieces 83a to 83c are tightened with the one-way screw 140 that rotates only in the tightening direction, but instead of this, the attachment piece 83a is formed with a fastening member such as a fracture attachment screw or a rivet. It is good also as a structure which clamps -83c, Furthermore, it is good also considering the 1st and 2nd fixing means which fixes a cover body and a box main body as a solvent or an adhesive for welding. Further, the one-way screw 140 attached to the attachment holes 86b to 86d is not necessarily provided in the circuit board box 62, and may be supplied at the time of inspection.

  In the above embodiment, the mounting holes 86a to 86d for mounting the one-way screw 140 are provided on the upper surface side of the circuit board box 62. However, the present invention is not limited to this, and the configuration may be provided on the side surface side of the circuit board box 62. Good. However, when the mounting holes 86a to 86d are provided on the upper surface side of the circuit board box 62 as in the embodiment, the mounting holes 86a to 86d are positioned to face the operator, so that the work is further facilitated. Yes. In addition, the cutting part (the connecting parts 84a to 84c / 85a to 85c) is more preferably provided with a cutting part at a position where it can be performed facing the back surface of the gaming machine (the upper surface of the circuit board box) as in this embodiment. Although it is easy to work, the positions of the mounting hole and the cutting part are not particularly limited. In addition, the circuit board box 62 is attached to the mechanism board 50, but is not limited thereto, and may be directly attached to the back surface of the game board 40.

  The material of the mounting piece may be any material such as metal or synthetic resin, but is preferably a synthetic resin that can be easily cut. Further, the detachable attachment piece portion is not necessarily provided on the lid body side, and may be provided on the box body side or may be provided on both sides of the lid body and the box body. Further, the number of attachment pieces is not particularly limited, and it may be one that can be reattached only once and can be inspected only once. However, the more mounting pieces are arranged in parallel, the greater the number of circuit board box inspections.

  Further, in the above-described embodiment (first embodiment), the engaging portion that engages and attaches the box main body 110 and the lid body 80 is the engaging claw 138 on the box main body 110 side and the locking hole on the lid body 80 side. 99, but is not limited to this configuration. For example, the projecting piece may be configured to engage with a groove-shaped or recessed opening, or may be configured as in the second to fourth embodiments described below. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted. First, in the circuit board box 160 of the second embodiment, as shown in FIG. 11, the mounting pieces 83 a to 83 c for fixing the box main body 110 and the lid body 80 with the one-way screw 140 are arranged in the width direction of the upper plate 81. It is provided only in the central part on one side. In this configuration, the circuit board box 62 is fixed to one minimum, in other words, one fixing one-way screw 140 is provided, so that the cost can be further reduced.

  Next, as shown in FIGS. 12A to 12C, the circuit board box 170 of the third embodiment includes a box body 172 to which the circuit board 171 is attached and a lid that covers the upper surface opening of the box body 172. And a body 176. A groove portion 173 is formed in each of two continuous side portions of the upper surface opening that forms a rectangular shape of the box body 172, and a slide movement described later is supported on one side portion where the groove portion 173 is not formed by supporting a lid 176. A supporting piece 174 for guiding is projected from the inward side. Further, four attachment holes 175 are formed at predetermined intervals on the side wall surface of the box body 172 from which the support piece 174 is projected. On the other hand, the lid 176 is formed of a rectangular flat plate, and the two sides forming the rectangular shape are formed as end pieces 177 that engage with the groove 173 of the box body 172. A plurality (four in the embodiment) of mounting pieces 178a to 178d are arranged in parallel on one side where the end piece 177 is not formed. The attachment piece portions 178a to 178c are connected to the lid body 176 via the connection portions 179a to 179c, respectively, and the attachment piece portion 178d is directly connected to the lid body 176. Moreover, between the attachment piece parts 178a to 178d, connecting parts 180a to 180c for connecting the respective parts are provided.

  A slit-like groove is formed between each of the mounting piece portions 178a to 178c and between the mounting piece portions 178a to 178c and the lid body 176, and the connecting portions 179a to 179c and 180a to 180c are The mounting piece portions 178a to 178d are provided so as to protrude from the outer wall surfaces (see FIG. 12B). In addition, the attachment pieces 178a to 178d are provided with four attachment holes 175 on the box body 172 side and attachment holes 181a to 181d corresponding respectively. In addition, each of the connecting portions 179a to 179c and 180a to 180c is provided with markings “1 to 3” for indicating a procedure for opening the circuit board box 170 (see FIG. 12A). Specifically, the connecting portions 179a and 180a corresponding to the mounting piece portion 178a are marked with “1”, and the connecting portions 179b and 180b corresponding to the mounting piece portion 178b are marked with “2”. The connecting portions 179c and 180c corresponding to the mounting piece 178c are marked with “3”.

  Thus, the lid body 176 and the box body 172 described above are configured as an assembly (circuit board box 170) that houses the circuit board 171 by the following assembly. First, the circuit board 171 is fixed to the box body 172 with screws 182. Next, the end piece 177 of the lid body 176 is engaged with the groove 173 of the box body 172, and the lid body 176 is slid in the direction E shown in FIG. A lid 176 is placed on the box body 172. Then, the mounting hole 181a of the mounting piece 178a is fixed to the mounting hole 175 of the box body 172 with a one-way screw (screw) 183, and the screw 183 locking portion is sealed with a rectangular hologram seal 184. Thus, an assembly (circuit board box 170) in which the circuit board 171 is housed in a sealed state in the internal space of the lid 176 and the box body 172 is configured. The screw 183 is fixed to the lid 176 and the box body 172 only at one place (one side) of the circuit board box 170, but the other three sides are fixed to the screw 183 (sealed state). Unless it is released, the engagement (engagement between the end piece 177 and the groove 173) cannot be released.

  A procedure for opening the circuit board box 170 for inspection of the circuit board 171 (inspecting whether the ROM is proper after delivery) and then restoring the closed state again will be described. First, in a closed state of the circuit board box 170, the hologram seal 184 is peeled off, and the connecting portions 179a and 180a are cut with a cutting tool such as a nipper, with the marking “1” as a mark. As a result, the attachment piece 178a is completely separated from the lid 176 and fixed to the box body 172 by the one-way screw 183, as shown in FIG.
