  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 ball lending switch is operated when borrowing a game ball by the card unit device 30. The return switch is for returning the card inserted into the card insertion slot 33 of the card unit device 30 at the end of the game. The frequency display LED displays the remaining amount of the card inserted into the card insertion slot 33 of the card unit device 30. Further, the automatic ball lending switch automatically operates when the game ball to be borrowed is operated by operating the ball lending switch and when the remaining amount of hitting balls on the upper plate 12 is not detected by the upper plate ball detector. 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 ball is automatically paid out to the upper plate 12 at the time of detecting, the above-described 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 attachment piece 122 described later is formed, and in the vicinity thereof, the attachment of the covering member 161 is performed. A mounting hole 111a for fitting the protrusion 166 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 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.

  A plurality of heat radiation 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. Upper end portions of both side walls in the longitudinal direction of the main body frame 116 are formed as attachment pieces 130 bent inward, and the attachment pieces 130 are individually provided with attachment holes 86a to 86d on the lid 80 side. Corresponding mounting holes 131 to 134 are formed. In the vicinity of the mounting holes 132 to 134, equipment holes 135 to 137 for mounting the equipment one-way screws 140 in an inserted state are formed. Further, locking grooves 138 for locking the engaging claws 96 on the lid 80 side are formed at two positions on the front end side of the mounting piece 130. Further, mounting protrusions 148a to 148d are formed at the lower end portion on one side in the longitudinal direction of the main body frame 116, and mounting holes 149a to 149d for individually mounting the circuit board box 62 to the mounting base 150 are formed. ing.

  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 overlapped and mounted on the main body frame 116, and the engagement protrusion 125 of the engagement piece 124 is inserted into the engagement hole 78 of the circuit board 61. Next, the connector 75 of the circuit board 61 is inserted into the insertion hole 158 to attach the covering member 161 to the connector mounting region 76, and the mounting hole 162 of the covering member 161 and the stop hole 77 of the circuit board 61 are attached to the mounting piece 122. The holes 123 are fastened together with screws 139. As a result, the covering member 161 and the circuit board 61 are fixed to the main body frame 116 with screws 139 across the bottom plate 111 (see FIG. 13A). In such mounting and fixing of the circuit board 61, when the hole positions of the retaining 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. Further, as shown in FIGS. 7 and 13, the connector mounting region 76 has a cover member 161 attached to the upper surface thereof, so that portions other than the connector 75, in other words, portions where the connection pattern 79 is formed are covered by the cover member 161. Covered. The covering member 161 covering the connection pattern 79 in this way is positioned with respect to the bottom plate 111 by fitting the mounting protrusions 166 into the mounting holes 111 a of the bottom plate 111.

  Next, the lid body 80 is put on the box body 110 whose upper surface is open. At this time, as shown in FIGS. 4 and 6, the four engaging claws 96 on the lid 80 side are respectively locked in the locking grooves 138 on the box body 110 side by insertion in the C to F directions. Positional attachment of the main body 110 and the lid 80 is performed. The engagement between the engaging claw 96 and the locking groove 138 is performed by first inserting the engaging claw 96 into the locking groove 138 as shown in FIGS. 12 (B) and 12 (D), the lid 80 (engaging claw 96) is slid and engaged with the locking groove 138. Since this engaged state is not released unless the fixed state is released, it becomes a substitute for the fixed portion. For this reason, the number of adhering portions can be reduced, and assembling is easy and cost reduction can be caused. That is, if there are such engaging portions at the four corners, it is not necessary to fix all the four corners (the four corners cannot be opened). The partition wall 98 of the lid frame 93 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 80. Thereby, it is possible to attach and remove the wiring to the connector 75 without removing the lid 80.

  4 and 6, the attachment hole 86a of the attachment piece 83a is fixed to the attachment hole 131 of the main body frame 116 with a one-way screw (screw) 140 (see FIG. 8A). The screw 140 stopper is sealed with a rectangular hologram seal 105. 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. In such a sealed state of the circuit board 61, the connector mounting region 76 that is exposed to the outside is covered with the connection pattern 79 by the covering member 156. For this reason, even in a configuration in which the connector mounting region 76 is exposed to the outside, an illegal act using the connection pattern 79 can be prevented. Further, in such an assembled state, the leading end portion of the partition wall 98 is in contact with the covering member 161, thereby arranging the regulating walls 164 and 165 inside the lid body 80. As a result, even when the screw 139 is removed by an unauthorized act, the covering member 161 cannot be removed unless the sealing state of the circuit board 61 (the fixing state of the lid 80) is released.

  Further, in the assembled state of the lid body 80 and the box body 110, the one-way screw 140 inserted through each of the equipment holes 135 to 137 is attached so that the lid body 80 covers from above the equipment body. It is accommodated in the box 62 without coming out of the holes 135-137. That is, in such a storage state, the upper wall surfaces near the attachment pieces 83b and 83c and the attachment hole 86d of the lid 80 individually prevent the one-way screw 140 from popping out. 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 diameters of the equipment holes 135 to 137 are approximately the same. 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 140 for assembling the lid 80 and the box main 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 discriminated. 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. In addition, 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, the circuit board box 62 secures the covering state of the circuit board 61 by sealing the screw 140 fixing portion between the lid 80 and the box body 110 with the hologram seal 105. 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.

  On the other hand, a plurality (three in the present embodiment) of mounting pieces 156a to 156c are arranged in parallel on the left end portion of the mounting base 150 described above. Connection portions 157a to 157c and 158a to 158c for connecting the mounting piece portions 156a to 156c with the substrate surface of the mounting base 150 are integrally formed. In addition, slit-shaped grooves are formed between the mounting pieces 156a to 156c and the board surface of the mounting base 150, and the connecting parts 157a to 157c and 158a to 158c are formed from the board surface of the mounting base 150. It is provided in a state of protruding upward. Further, attachment holes 159a to 159c are formed in the attachment pieces 156a to 156c, respectively, and an attachment hole 159d is formed on the substrate surface of the attachment table 150 adjacent to the attachment pieces 156c. These mounting holes 159a to 159d correspond to the mounting holes 149a to 149d of the main body frame 116 individually.

  Thus, the mounting base 150 is attached 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. Thereafter, the sliding movement of the box 62 causes the release lever 153 on the mounting base 150 side to elastically deform downward, 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 box 62 is mounted. Then, the mounting hole 149a formed in the mounting protrusion 148a of the circuit board box 62 is fastened together with the mounting hole 159a of the mounting piece 156a with the one-way screw 160, so that the circuit board box 62 is not attached to the mounting base 150. Install with reversible fixation.

  By the way, in the state where the circuit board box 62 is attached to the ball and ball game machine 1 via the mounting base 150, as shown in FIG. 2, the circuit board box 62 is attached so that the covering member 161 is disposed on the upper side. In other words, the circuit board box 62 shown in FIG. For this reason, even when the fixed state between the lid 80 and the box main body 110 is released by inspection of the circuit board 61 to be described later, the engagement claw 96 on the lid 80 side and the locking groove 138 on the box main body 110 side. Since the engaged state (the state in which the engaging claw 96 is hooked on the locking groove 138 and the lid body 80 is hung on the box body 110) is maintained, the circuit board box 62 can be easily opened and closed.

  Next, a procedure for opening the circuit board box 62 described above for inspection of the circuit board 61 (inspecting whether the ROM is genuine after delivery) and then restoring the closed state again based on FIG. I will explain. First, in the closed state of the circuit board box 62 shown in FIG. 10A, after peeling off the hologram seal 105 attached to the screw 140 stop portion of the mounting piece 83a, each connecting portion is marked with the stamp “1”. 84a and 85a are cut with a cutting tool such as a nipper. As a result, the attachment piece 83 a is completely separated from the lid 80 and is fixed to the box body 110 by the one-way screw 140. In other words, the cover 80 is completely fixed to the box body 110, and the circuit board box 62 can be opened. Then, as shown in FIG. 10B, the lid body 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 the circuit board box 62 is closed, as shown in FIG. 10C, the cover piece 80 is put on the box body 110 and the taken-out one-way screw 140 is marked with the marking “2” as an attachment piece. It is screwed into the mounting hole 86b of 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. The circuit board box 62 is restored to the closed state again by attaching a new hologram seal 105 to the screw 140 stop portion of the mounting piece 83b.

  Thereafter, when the circuit board box 62 is inspected again (second inspection), 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. After that, similarly, 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 screwed into the mounting hole 86c of the mounting piece 83c with the mark "3" as a mark. Then, a new hologram seal 105 is attached. 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 attachment pieces 83c are separated from the lid 80 by cutting the connecting portions 84c and 85c with the marking “3” as a mark. Then, the circuit board box 62 is opened. Further, when the circuit board box 62 is restored, 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 is screwed into the last remaining mounting hole 86d to form a new hologram. A seal 105 is attached.

  By the way, in the closed state of the circuit board box 62 described above, unless the connection portions 84a to 84c and 85a to 85c are cut to disconnect the attachment pieces 83a to 83c and the upper plate 81, the circuit board box 62 is It 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, 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 sticker 105 is peeled off, a trace of the hologram sticker 105 remains firmly, so that it is immediately known that fraud has been performed.

  Next, a procedure for replacing the circuit board box 62 due to an unexpected failure of the circuit board 61 will be described with reference to FIG. First, in the fixed state of the circuit board box 62 and the mounting base 150 shown in FIG. 11A, the connecting portions 157a and 158a are cut with a cutting tool such as a nipper. As a result, the mounting piece 156a is completely separated from the mounting base 150 and is fixed to the circuit board box 62 by the one-way screw 160. That is, the circuit board box 62 is released from the mounting base 150 by being released from the mounting base 150. Then, 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 in the G direction shown in FIG. Remove. Thereafter, as shown in FIG. 11C, a new circuit board box 62 ′ is slid onto the mounting base 150, and the mounting protrusion 148b is fastened to the mounting piece 156b with a one-way screw 160, whereby the circuit board box 62 ′. Is attached to the mounting base 150 in an irreversible fixed state.

  The above-mentioned circuit board box replacement work is performed by a sales person on the circuit board box manufacturer side, and the sales person displays his / her name (exchanger) on the replacement history sticker 91 as shown in FIG. "Sakuma") and the replacement date "April 1, H9" are entered to indicate in the circuit board box 62 'that they have been replaced. Furthermore, when the sales person brings the old box 62 home, if the replacement date, serial number, amusement store name, etc. are input to the manufacturer's maintenance management computer, whether or not the circuit board box has been replaced illegally. Judgment can be facilitated. In other words, if the manufacturer does not have the record, it is counterfeit. Of course, if there is no description of replacement in the replacement history seal 91 and the box is not fixed, fraud can be determined from this. The serial number may be written on the seals 89 and 91, or may be written on the seals 104 and 105 for sealing. Further, the replacement history seal 91 may be affixed at the time of replacement, or may be affixed to a new circuit board box at the time of replacement. Further, the history sticker may be used for entering an inspection history.

  After that, when the circuit board box 62 ′ is replaced again (second replacement), the connecting portions 157b and 158b are cut to release the fixing between the circuit board box 62 ′ and the mounting base 150, and the circuit board box 62 ′. 62 ′ is removed from the mounting base 150. Next, a new circuit board box is slid onto the mounting base 150, and then the new circuit board box mounting protrusion 148c is fastened to the mounting piece 156c with a one-way screw 160, whereby the circuit board box is attached to the mounting base 150. Install with irreversible fixation. Thereafter, when the circuit board box is replaced (third replacement), the old circuit board box is removed from the mounting base 150 by cutting the connecting portions 157c and 158c. Then, the new circuit board box is slid onto the mounting base 150, and the mounting protrusion 148d is fixed to the mounting piece 156d with the one-way screw 160. This completes the third replacement of the circuit board box.

  Further, as shown in FIG. 2, the game control circuit board 61 accommodated in the circuit board box 62 has a wiring 167 connected to various connectors 75. The wiring 167 includes one connector. A wiring tube 168 is attached to each of a plurality of units each having 75 as a unit. The wiring tube 168 is made of colorless and transparent vinyl, and protects the wiring 167 from the outside by bundling a plurality of wirings 167 and covering the outer periphery of the wiring 167. For this reason, even when an unauthorized substrate is connected to the wiring 167 and hidden in the wiring tube 168, the unauthorized portion can be easily found through the colorless and transparent wiring tube 168.

  As described above, the ball game machine 1 according to the present embodiment includes the circuit board box 62 including the box body 110 and the lid 80 for housing the game control circuit board 61, and the circuit board box 62 as the ball game machine. 1, and the mounting base 150 and the circuit board box 62 are attached to each other by attachment fixing means (one-way screw 160, attachment projections 148a to 148c, attachment pieces 156a to 156c). The box main body 110 and the lid body 80 are assembled by an assembling and fixing means (one-way screw 140, mounting piece portions 83a to 83c, and mounting piece 130) to be in an irreversible fixing state. To do. With this configuration, the circuit board box 62 is closed in an irreversible fixed state, and the circuit board box 62 is attached to the ball game machine 1 (mounting base 150) in an irreversible fixed state. Thus, it is possible to prevent an unauthorized act of opening the circuit board box 62 and an unauthorized act of replacing the circuit board box 62 with a duplicated product.

  The mounting fixing means includes first and second mounting fixing means, and a connecting portion for releasing the fixing state by the first mounting fixing means (one-way screw 160, mounting protrusion 148a, mounting piece 156a). 157a and 158a are provided, and the mounting base 150 and the circuit board box 62 are connected to the second mounting fixing means (one-way screw 160, mounting protrusions 148b and 148c, mounting piece portions 156b and 156c in a state where the connecting portions 157a and 158a are released. The circuit board box 62 can be replaced due to an unexpected failure or the like. In the present embodiment, since the connecting portions 157b, 157c, 158b, and 158c for releasing the fixed state by the second mounting and fixing means are also provided, the circuit board box can be replaced a plurality of times.

  The assembly fixing means includes first and second assembly fixing means for releasing the fixing state by the first assembly fixing means (one-way screw 140, attachment piece 130, attachment piece portion 83a). Connecting portions 84a and 85a, and the box main body 110 and the lid 80 are connected to the second assembly fixing means (one-way screw 140, mounting piece 130, mounting piece portion 83b) in the released state of the connecting portions 84a and 85a. 83c), the circuit board 61 can be inspected on the premise that it is restored to the circuit board box 62 having a high crime prevention effect. Moreover, in this embodiment, since the connection part 84b * 84c * 85b * 85c for canceling | released the adhering state by a 2nd assembly | attachment adhering means is also provided, it restores to the circuit board box 62 with a high crime prevention effect again. As a result, the circuit board 61 can be inspected a plurality of times.

  The above-described embodiment (first embodiment) does not limit the present invention, and various modifications can be made within the scope of the present invention. Hereinafter, other configurations will be described as second to sixth embodiments. In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. First, in the first embodiment, the circuit board box 62 is attached to the mechanism plate 50 via the attachment base 150, and the attachment base 150 and the mechanism plate 50 are attached by detachable screws. It is not limited to. In the ball game machine 170 of the second embodiment, as shown in FIGS. 14 and 15, a mounting base 150 for mounting the circuit board box 62 is mounted on the game board 40 via the mounting board 173. The mounting substrate 173 is a rectangular flat plate, and bent flange portions 174 are formed on the left and right ends thereof. An attachment hole 177 is formed in the flat plate portion of the attachment substrate 173, and an attachment hole 175 is formed in the flange portion 174. Accordingly, the attachment board 173 is attached to the back surface of the game board 40 in an irreversible fixed state by the one-way screw 176 being screwed into the attachment hole 175 of the flange portion 174.

  Further, with respect to the mounting board 173 described above, the mounting board 173 is fixed in an irreversible fixed state by the fastening hole 155 of the mounting base 150 being fastened together with the mounting hole 177 with a one-way screw 178. Attached to. And the circuit board box 62 (similar to 1st embodiment) is attached to the mounting base 150 attached in this way similarly to said 1st embodiment. Further, a mechanism plate 171 is provided on the back side of the ball game machine 170 so as to be openable and closable. A drum type variable display device 41 provided at the center of the mechanism plate 171 so as to protrude from the back side of the game board 40 is provided. A window opening 172 penetrating the circuit board box 62 is opened.
