Description

  The present invention relates to a gaming machine provided with a board storage box for storing a circuit board.

  As the gaming machines, there are a ball game machine, a slot machine, and the like that play a game using a game medium, generate a specific gaming state when a predetermined display result is obtained by variably displaying identification information. The specific game state means a state advantageous for a player who is given a predetermined game value. Specifically, for example, a state in which a predetermined game value is given such as a state in which a right to be advantageous to the player has occurred, a state in which conditions for paying out premium game media are easily established, and the like State.

  Such a gaming machine is provided with many circuit boards. In particular, a microcomputer (for example, peripheral circuits such as a CPU, a ROM, a RAM, and an I / O port unit) is mounted on the game control circuit board that controls the progress of the game. In many cases, different game contents can be realized by exchanging the ROM storing the program for controlling the progress of the game of the microcomputer.

For this reason, the game control circuit board is usually provided in a sealed state in the circuit board box to prevent unauthorized actions such as ROM replacement. Many circuit board boxes are composed of a transparent synthetic resin box-like main body that supports the game control circuit board and a transparent synthetic resin cover body that covers the game control circuit board. Yes. In such a circuit board box, the box-shaped main body and the cover body are fixed by screwing with a one-way screw that can rotate only in one direction to the mounting portion provided on both the box-shaped main body and the cover body, As long as the attachment portion is not cut, a state in which the box-shaped main body and the cover body cannot be released is proposed, and a game control circuit board is prevented from being illegal (see, for example, Patent Document 1).
JP 2002-35374 A (page 7-11, FIG. 6)

  However, in the circuit board box described above, since a separate member such as a screw is used to fix the box-shaped main body and the cover body, there is a risk that the screw may be lost and a tool is used when fixing the screw or the like. In other words, since the box-shaped main body and the cover body are fixed by the mounting part itself screwed in with screws, the mounting part is required to have strength, and when the fixing part is released, there is another need to cut the mounting part. Tools etc. were necessary. Further, since the cutting part is formed integrally with the box-shaped main body and the cover body, when all the cutting parts are cut, the box-shaped main body and the cover body cannot be reused. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine that can prevent fraud with respect to the game control circuit board and improve workability when inspecting the game control circuit board. There is to do.

  In order to achieve the above object, according to the first aspect of the present invention, a gaming machine (for example, a ball game) including a circuit board storage box (for example, main board box 150) for storing a circuit board (for example, main board 151). In the machine 1), the board housing box includes a main body (for example, a box-shaped main body 190) on which the circuit board is supported and a lid (for example, a cover body 210) that covers at least the circuit board supported by the main body. And slides in only one direction on a rail-like rail-like portion (for example, rail-side portion 235) provided along a predetermined side of the outer surface of either the main body or the lid. When the possible slide seal member (for example, slide seal member 220) is detachably mounted and the main body and the lid are combined on the other outer surface, the slide seal An opening prevention protrusion (for example, an opening prevention protrusion 245) is provided at a position below the material, and the slide sealing member is further combined with the main body and the lid on the outer surface of either the main body or the lid. Is provided with a slide prevention protrusion (for example, a slide prevention protrusion 246), and the slide sealing member is a plate-like part (for example, protruding from one of the main body and the cover body). , Plate-like portion 221), cutout portions (for example, cutout portion 222) provided at a plurality of locations of the plate-like portion, and a plurality of cutout portions protruding outward from the outer surface of the plate-like portion. A plurality of slide excision parts (for example, slide excision part 223) that can be artificially excised, and the notch part at an insertable position through which the opening preventing projection can be inserted when the main body and the lid are combined. But In the state (for example, the state of FIG. 9E), the opening prevention protrusion is inserted into the notch and positioned below the plate-like part, and then the slide sealing member is attached to the opening prevention protrusion. A sealing state in which the lid body cannot be removed from the main body by sliding to a position covered by the plate-like part that is not a part and making the opening prevention projection into a non-insertable position where the notch part cannot be inserted. For example, the state shown in FIG. 9C) and after the slide excision portion is excised (for example, after the state shown in FIG. 9D), the slide sealing member is slid to the next notch portion. , And the openable state (for example, the state of FIG. 9E) in which the lid can be removed from the main body.

In the invention of claim 2, a slip-off prevention part (for example, a plurality of reverse-direction slide prevention claws (for example, the retrograde prevention protrusions 224) arranged in parallel on either the slide sealing member or the rail side part ( For example, an engagement hook portion (for example, an inner side surface facing the tip end surface of the rail side portion 235 in the hollow portion of the slide seal member 220) and engaged with one of the plurality of reverse-direction slide prevention claws on the other side (for example, The anti-reverse hook 238) is provided, and the slide seal member is slid in the one direction (for example, the left direction in FIG. 9) without the engagement hook portion and the reverse slide prevention claw being engaged. The sliding in the reverse direction opposite to the one direction (for example, the right direction shown in FIG. 9) is prevented by the engagement between the engagement hook portion and the reverse-direction slide prevention claw, and the notch portion is Above When in the passable position, the engagement hook portion and the reverse-direction slide prevention claw are engaged with each other (for example, in FIG. 9E, the reverse-motion prevention projection 224 and the reverse-motion prevention hook 238 are The slide sealing member is stopped in a state where the notch is in the insertion-possible position by being engaged). In the invention of claim 3, the main body or the lid The anti-sliding protrusion is provided on one of the anti-opening protrusions (for example, the anti-opening protrusion 245 and the anti-sliding protrusion 246 are provided on the cover body 210).

  Further, in the invention of claim 4, the main body is provided with a rail-shaped side part to which the slide sealing member is attached (for example, a rail-side part 235 is projected from the box-shaped main body 190, and the rail side part is provided. The slide sealing member 220 is attached to the box-shaped main body 190 by engaging the upper projection 236 and the lower projection 237 of the 235 with the inner surface of the hollow portion of the slide sealing member 220).

  In the invention which concerns on Claim 1, the slide sealing member which can be slid only to one direction is attached to the rail-shaped installation part provided along the predetermined | prescribed side of either the main body or the said cover body so that it cannot remove. Then, when the main body and the lid are combined, with the notch in the insertion-possible position where the release preventing protrusion can be inserted, the opening preventing protrusion is inserted into the notch and positioned below the plate-like part, and then slides. The sealing member is slid to a position where the opening prevention protrusion is covered by a plate-like part that is not a notch, and the opening prevention protrusion is set to a non-insertable position where the notch cannot be inserted. After the slide excision part is excised, the slide sealing member can be slid to set the next notch part to the insertable position, and the lid can be removed from the main body. In order to perform fraudulent acts on the circuit board, the slide excision must be excised, and when the slide excision is excised, the trace remains, so the main body and the lid can be easily released from the fixed state. The fraudulent act can be suppressed and the fraudulent act can be easily detected when the fraudulent act is performed. In addition, since the slide excision part is provided separately from the main body and the lid body, the main body and the lid body can be reused by exchanging the slide sealing member even when all the slide notches are excised. Furthermore, after the slide excision part is excised, the slide sealing member is slid to be in a sealed state, so there is no need for a tool or the like when changing from an openable state to a sealed state, Since the lid is not fixed to the main part at the part that is cut off or cut when it is changed from the sealed state to the openable state, it becomes possible to make the part to be cut relatively fragile, and to make it openable Since a design that does not require tools is possible, workability is further improved.

  In the invention according to claim 2, the slide seal member is slid in one direction without the engagement hook portion and the reverse-direction slide prevention claw being engaged, and in the reverse direction opposite to the one direction. Sliding is prevented by the engagement of the engagement hook portion and the reverse-direction slide prevention claw, and the engagement hook portion and the reverse-direction slide prevention claw are engaged when the notch portion is in the insertion-possible position. Because the slide sealing member is stopped in a state where the cutout portion is in the insertion-possible position, it is possible to prevent the sealing state from being unintentionally opened when the opening state is enabled, and the workability in the opening state is possible. improves.

  In the invention according to claim 3, since the anti-sliding protrusion is provided on one of the main body or the lid provided with the anti-opening protrusion, the anti-opening protrusion and the anti-sliding protrusion can be formed integrally, and molding is easy. become. In addition, since the opening prevention protrusion and the sliding prevention protrusion are provided at relatively close positions, it is possible to easily grasp the positional relationship between the opening prevention protrusion, the slide prevention protrusion, and the slide excision part during operation of the slide sealing member. Improves.

  In the invention according to claim 4, generally, the main body on which the circuit board is supported is configured to have a thickness greater in the depth direction than the lid so as to accommodate the board on which various ICs are mounted. Even if a member is provided, in order to attach the slide sealing member, it is not necessary to increase the thickness of the outer side in accordance with the size of the slide sealing member. Therefore, the board box can be molded without increasing the thickness of the whole board box by providing the rail-shaped side part to which the slide sealing member is attached to the main body.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, an overall configuration of a bullet ball gaming machine 1 which is an example of a gaming machine will be described. FIG. 1 is a front view of the ball game machine 1 as seen from the front.

  The bullet ball game machine 1 according to the present embodiment is a jackpot determination random number that is updated (counted up) at a predetermined cycle when the game control microcomputer starts a winning prize (for example, a hitting ball enters the starting prize port 14). A random number for jackpot determination is extracted from the counter, and specified to the display unit 12 based on the determination that it matches the jackpot determination value when the variable display device 21 starts variable display of the special symbols 12a to 12c. After displaying the display result (big hit symbol), it has a function of controlling to a big hit gaming state as a specific gaming state advantageous to the player.

  On the upper and left sides of the display unit 12, a hold as a hold storage means for storing the extraction order of the random numbers for jackpot determination extracted when the start condition is satisfied (the hit ball wins the start winning opening 14) in an identifiable manner. Special symbol hold memory that displays the number of stored big hit determination random numbers (pending storage number) stored in a storage buffer (for example, a function for storing a big hit determination random number or the like by the RAM 55 mounted on the main board 151). A display 13 is provided. This special symbol hold memory display 13 is constituted by four LEDs and has an effective start prize (in this embodiment, a start prize when the number of numerical data stored in the hold memory buffer is less than 4). The LED is turned on every time, and the LED that is turned on is reduced by 1 every time variable display of the special symbols 12a to 12c is started.

  In this embodiment, the special symbol storage memory display 13 for displaying the number of numerical data stored in the storage buffer (the number of storage) is provided separately from the display unit 12. It is good also as a structure which provides the special symbol reservation memory | storage display area which displays the memory | storage number (holding memory number) of the numerical data memorize | stored in the storage memory buffer in the part 12. FIG. In this case, the display unit 12 and the special symbol hold storage display area are provided separately, so that the numerical value stored in the hold storage buffer in the special symbol hold storage display area even during the variable display of the special symbols 12a to 12c. The number of stored data (the number of stored storage) can be displayed. In addition, a hold storage display area may be provided in a part of the display unit 12. In this case, during variable display, the number of numerical data stored in the hold storage buffer (the number of hold storages) is displayed. Just stop.

  Below the variable display device 11, a variable winning device 15 having a start winning port 14 through which a game ball can be won is provided. The winning ball that has entered the start winning opening 14 is guided to the back of the game board 9 and detected by the start opening switch 62. The variable winning device 15 is opened by a solenoid 66. When the variable winning device 15 is opened by the solenoid 66, it becomes easier for the game ball to win the start winning port 14 (easier to start winning), which is advantageous to the player.

  Below the variable winning device 15, a special variable winning device 20 that is opened by a solenoid 67 in a specific gaming state (big hit gaming state) based on the specific display result (big hit symbol) being derived and displayed on the display unit 12. Is provided. The special variable prize-winning device 20 is a means that includes a big prize opening inside and opens and closes the big prize opening. Of the winning balls led from the special variable winning device 20 to the back of the game board 9, the winning ball that entered one (V winning area) is detected by the V winning switch 64 and enters the other (10 count winning area). The winning ball is detected by the count switch 63. On the back of the game board 9, a solenoid 68 for switching the route in the special winning opening is also provided.

  On the right side of the special variable prize-winning device 20, there is provided a normal symbol display 16 composed of a pair of LEDs marked with “O” and “X”. The normal symbol display 16 can variably display a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  When a game ball passes through the gate 28 and is detected by the gate switch 61, a random number for normal symbol determination is extracted from a counter updated at a predetermined cycle and stored in a normal symbol buffer of the RAM 55 mounted on the main board 151. . In this embodiment, the upper limit of the number of random numbers for determination per normal symbol that can be stored in the normal symbol buffer of the RAM 55 is four. If the number of random numbers for determination per normal symbol stored in the normal symbol buffer has not reached the upper limit, that is, the number of random numbers for determination per normal symbol stored in the normal symbol buffer has reached four. Otherwise, a random number for normal symbol determination is extracted. If the normal symbol display 16 can start the variable display in which the normal symbol display state changes ("◯" and "x" are alternately lit), the normal symbol display 16 can display the normal symbol variably. Is started. If the normal symbol display 16 is not in a state in which variable display in which the display state changes can be started, the normal symbol per-symbol determination random number is stored in the normal symbol buffer to increase the number of normal symbol per-symbol determination random numbers stored by one.

  Further, on the left side of the special variable winning device 20, there is provided a normal symbol holding storage display 17 having a predetermined number (four in this embodiment) of LEDs for displaying the number of random numbers for determination per normal symbol. ing. The normal symbol hold memory display 17 increases the number of LEDs that are turned on each time a game ball passes through the gate 28 and is detected by the gate switch 61. Each time the variable display of the normal symbols (for example, “◯” and “x”) is started on the normal symbol display 16, the number of LEDs that are lit is reduced by one. Note that the special symbols 12a to 12c and the normal symbols can be variably displayed on one display unit 12. In this case, the special symbol display area for variably displaying the special symbols 12a to 12c and the normal symbol display area for variably displaying the normal symbols are realized by one display unit 12.

  In this embodiment, the normal symbol display 16 performs variable display of the normal symbol by alternately lighting up and down lamps marked with ○ and × (the symbol becomes visible when lit), The variable display continues for a predetermined time (for example, 29.2 seconds). Then, if the left lamp marked with ○ is turned on at the end of the variable display, it is a win. Whether or not to win is determined by whether or not the random number for normal symbol extraction extracted when the game ball passes through the gate 28 and the game ball is detected by the gate switch 61 matches the predetermined normal symbol determination value. It is determined by whether or not. If the display result of the variable display on the normal symbol display 16 is a win, the variable winning device 15 is opened a predetermined number of times for a predetermined time, so that the game ball is likely to win the start winning opening 14. That is, the state of the variable winning device 15 changes from an unfavorable state (blocked state) to an advantageous state (open state) when the stop symbol of the normal symbol is a winning symbol.

  A decorative lamp 25 blinkingly displayed during the game is provided around the left and right of the game area 10 of the game board 9, and an out port 26 into which a hit ball that has not won a prize is taken in at the bottom.

It has been.

  In addition, the ball game machine 1 is provided with a ball hitting device 87 that drives a drive motor by operating the hit ball operating handle 8 and uses the rotational force of the drive motor to launch a game ball into the game area 10. (See FIG. 2). A game ball launched from the ball hitting device 87 enters the game area 10 through a ball hitting rail mounted in a circular shape on the game board 9 so as to surround the game area 10, and then descends the game area 10. . When the hit ball enters the start winning opening 14 and is detected by the start opening switch 62, if the variable symbols of the special symbols 12a to 12c can be started (for example, the end of the big hit game or the end of the previous variable display), the display unit 12, variable display (variable display) of special symbols 12 a to 12 c is started. If variable display of special symbols 12a-12c cannot be started, the number of numerical data stored in the reserved memory buffer (for example, random numbers for jackpot determination) is increased by 1, and the special symbol reserved memory display 13 is turned on. Add one more LED.

  The variable display of the special symbols 12a to 12c on the display unit 12 stops when a certain time has elapsed. When the special symbols 12a to 12c at the time of stop become a big hit symbol (specific display result), the game shifts to a big hit gaming state. In other words, the special prize winning device 20 is opened by the special variable prize winning device 20 until a predetermined time elapses or until a predetermined number (for example, ten) of hit balls wins the big prize winning opening. It should be noted that one round in the big hit gaming state is that until a certain period of time elapses after the special prize winning device 20 is opened and closed or until a predetermined number (for example, ten) of hit balls wins the big prize opening. It is. When the special variable prize winning device 20 opens the big prize opening, the hit ball enters the V winning area in the big prize winning opening, and when it is detected by the V prize winning switch 64, a continuation right is generated and the special variable prize winning device 20 generates a large amount. The prize opening is opened again. The generation of the continuation right is allowed a predetermined number of times (for example, 15 rounds).

This is an effect control microcomputer that controls the light emitters such as lamps and LEDs provided in the display unit 12, the speaker 27, and the ball and ball game machine 1 based on the effect control command (control signal).

  Next, the detailed structure of the main board box 150 which comprises the principal part of this embodiment is demonstrated. FIG. 4 is a perspective view showing an attached state of the power supply unit box 136 and the main board box 150 that are attached to the left side portion when viewed from the back of the lower component part of the mechanism plate 100.

  As shown in FIG. 4, the main board box 150 is attached to the conductive mounting base 250, and the engaging piece 255 formed on the bottom surface of the mounting base 250 is inserted into the horizontal projection plate 160 described above. 162 and the L-shaped protruding plate 165 can be easily engaged by engaging with the insertion groove 166.

  The mounting base 250 is formed in a substantially rectangular shape by a substantially rectangular conductive metal plate (or conductive synthetic resin), and its periphery is bent to form reinforcing pieces 251 to 254. Engagement holes 257 into which the engagement protrusions 205 protruding from the left and right of the box-shaped main body 190 are inserted are formed above and below the vertical reinforcing pieces 252 and 254 in the drawing. In addition, the substantially central portion of the other reinforcing piece 254 is a locking piece portion 258 that extends outward without being bent, and the locking piece portion 258 includes a locking member 258 (not shown). A locking hole 259 for locking the locking claw of the locking lever is formed. In order to reinforce the locking piece portion 258, a bead processing portion 260 is formed above and below the locking piece portion 258. Note that only the reinforcing piece 251 on the upper side is bent outward, and when the mounting base 250 is attached to the horizontal protruding plate 160 of the mechanism plate 100, the reinforcing piece 251 becomes the upper side portion of the horizontal protruding plate 160. It comes to contact with.

  Furthermore, the engagement pieces 255 are punched and formed at four locations on the top, bottom, left, and right bottom surfaces of the mounting base 250, and elastic contact pieces 261 are punched and formed on the bottom left bottom surface and the top right bottom surface of the mounting base 250. For this reason, punching openings 256 and 262 (see FIG. 5) are respectively formed on the bottom surface where the engagement piece 255 and the elastic contact piece 261 are formed. The engagement piece 255 is inserted into the insertion groove 162 formed in the horizontal projecting plate 160 and the insertion groove 166 formed in the L-shaped projecting plate 165, and the mounting base of the control board box 79 described above. The engaging piece (not shown) of the (not shown) and the insertion groove (not shown) of the winning ball guiding cover body 71 can be locked by the same action. By the way, the position where the elastic contact piece 261 is formed is a position where the lower end of the conductive screw for fixing the main board 151 to the box-shaped main body 190 comes into contact when the main board box 150 is attached to the mounting base 250. It has become. The elastic contact pieces 261 are each formed to have an upward slope toward the end of the mounting base 250.

  In order to mount the main board box 150 on the mounting base 250 configured as described above, the left side of the main board box 150 is slanted downward and comes into contact with the mounting base 250, and then is slid in the left direction in the figure to engage. The protrusion 205 is inserted into the engagement hole 257. At this time, the lower left portion of the main board box 150 pushes the lower left elastic contact piece 261 downward, and the elastic contact piece 261 has an upward slope with respect to the sliding direction. There is no hindrance to the insertion work into the joint hole 257. After the engagement protrusion 205 is inserted into the engagement hole 257, the right side of the main board box 150 is brought into contact with the mounting base 250, and then the main board box 150 is slid to the right side to place the engagement protrusion 205 into the engagement hole 257. At the same time, the locking lever 206 of the locking lever 206 is engaged with the locking hole 259. As a result, the main board box 150 can be completely attached to the mounting base 250. Even when the main board box 150 is slid in the right direction, the upper right elastic contact piece 261 has an upward slope with respect to the sliding direction, so that the engagement protrusion 205 and the engagement hole 257 are engaged. The operation of engaging the engaging lever 206 of the engaging lever 206 with the engaging hole 259 is not hindered.

  In the state where the main board box 150 is attached to the mounting base 250 as described above, the tip contact surface of the conductive screw 242 contacts the elastic contact piece 261 of the mounting base 250 formed of a conductive metal plate. It has become a state. Since the conductive screw 242 is in contact with the ground line of the main board 151, noise that has entered the main board 151 is discharged to the outside via the conductive screw 242, the elastic contact piece 261, and the mechanism plate 100. be able to. For this reason, conventionally, since the main board box has been made transparent, it has become a board box that is difficult to use conductive members and is vulnerable to noise. However, if configured as in this embodiment, it can sufficiently cope with noise. Is. Further, compared to a conventional board box in which a ground wire is connected, the ground structure can be realized simply by mounting the main board box 150 on the mounting base 250, and therefore it is very simple.

  When removing the main board box 150 from the mounting base 250, the entire lever is slid leftward while pressing the locking lever 206 toward the inside of the main board box 150, and the engagement protrusion 205 on the right side of the figure is engaged. The engagement with the engagement hole 257 is released, and the right side of the main board box 150 is lifted and slid to the right to release the engagement between the engagement protrusion 205 and the engagement hole 257 on the left side of the figure, thereby The main board box 150 can be easily removed from the mounting base 250. Further, the mounting of the main board box 150 to the mounting base 250 can be performed even when the mounting base 250 remains attached to the mechanism plate 100.

  Further, the region where the power supply unit box 136 is attached is formed in a concave shape slightly toward the front side. That is, the transparent side wall plate 178 that constitutes the side wall of the mounting space of the power unit box 136 is slightly deeper to the front side than the mechanism plate 100 of the lower right component part shown in FIG. Mounting bosses having a pair of mounting holes 175 are formed on the upper left and right sides of the transparent side wall plate 178, and a pair of engagement holes 167 are formed on the lower left and right sides of the transparent side wall plate 178. The engagement holes 167 are formed at the corners of the L-shaped projecting plate 165 projecting from the transparent side wall plate 178 at a right angle toward the back surface. An insertion groove 166 for detachably mounting a lower portion of a mounting base 250 for mounting the main board box 150 is formed at the tip of the L-shaped protruding plate 165. The insertion groove 166 will be described later in detail. In addition, reinforcing ribs 177 project in a rectangular shape on the back surface of the transparent side wall plate 178 in order to reinforce the mounting space.

  Thus, in order to attach the power supply unit box 136 to the mounting space configured as described above, the power supply unit box 136 is inserted into the engagement holes 167 after the engagement protrusions 173 projecting on both lower sides of the power supply unit box 136 are inserted. It can be easily attached by fixing the screws 176 so that the mounting holes of the mounting pieces 174 projecting on both upper sides of the box 136 correspond to the mounting holes 175 described above. In this case, since the power supply unit box 136 is attached to the front side (side closer to the game board 9) than the mechanism plate 100 of the lower right component, the amount of protrusion of the power supply unit box 136 to the back side Can be suppressed. In particular, since the power supply unit board 137 is mounted with a heat sink or a large capacitor having a height (thickness) compared to other control boards, the power supply unit box 136 that houses the power supply unit board 137 is also thick. Even if the power supply unit box 136 having such a thickness is attached, the protruding amount on the back side can be suppressed. On the back side of the power supply unit box 136, a main board box 150 that houses a main board 151 for controlling the game operation is detachably attached. As shown in FIG. 4, the attachment is performed on a horizontally projecting plate 160 that is bridged in a slightly upper part from the lower side of the opening window 102 of the mechanism plate 100.

  Next, the main board box 150 will be described with reference to FIGS. 5 is an exploded perspective view of the main board box 150, FIG. 6 is a front view of the main board box 150, and FIG. 7 is a diagram for explaining the engagement between the box-shaped main body 190 and the cover body 210. It is sectional drawing.

  The main board box 150 is configured by assembling a plurality of covering members. As the plurality of covering members, a box as a main body that covers the back surface of the main board 151 as a circuit board and supports the main board 151. The main body 190 and a cover body 210 as a lid body that covers at least the electronic component mounting region (surface) of the main substrate 151 that is covered and supported by the box-shaped main body 190. The box-shaped main body 190 and the cover body 210 are all formed of a non-conductive transparent synthetic resin whose inside can be visually recognized. Hereinafter, the respective covering members (the box-shaped main body 190 and the cover body 210) and the main board 151 constituting the main board box 150 will be described in detail.

  First, the box-shaped main body 190 will be described in detail. The box-shaped main body 190 is formed in a rectangular parallelepiped shape with an open upper surface, and positioning projections 192 and mounting bosses 193 for fixing and supporting the main board 151 are slightly inside the four corners inside (upper surface) of the bottom plate 191. Is protruding. The positioning protrusion 192 protrudes from one diagonal end of the bottom plate 191, and the mounting boss 193 protrudes from the other diagonal end, and an attachment hole is formed at the center thereof. Thus, the positioning projections 192 are fitted with positioning holes 240 formed in one diagonal corner of the main board 151, and the mounting boss 193 is fitted in the other diagonal corner of the main board 151. The mounting holes 241 to be formed are made to correspond to each other and are fixed by conductive screws 242 described later. However, when the main substrate 151 is fixed as described above, a plurality of support protrusions 194 that support the back surface (solder surface) of the main substrate 151 are formed at appropriate intervals on the inner periphery of the side wall of the box-shaped main body 190. Yes.

  Further, a protruding piece portion 208 protrudes from one side of the upper side wall and one side of the upper side wall of the box-shaped main body 190, and the protruding piece portion 208 is engaged with the cover body 210. An engagement step groove 195 that fits with the protruding piece 217 is formed. The engagement step groove 195 has a first step groove 195a and a second step groove 195b formed in a crank shape, and after the engagement protrusion 217 of the cover body 210 is first dropped into the first step groove 195a. Then, the box-shaped main body 190 and the cover body 210 are engaged by sliding toward the side (right side in FIG. 5) and dropping the engaging protrusion 217 into the second step groove 195b. The two-stage drop-in structure as described above is adopted because the connectors 151a to 151i mounted on the main board 151 are smoothly inserted into the connector through holes 213 of the pattern covering plate 212 described later, and the box-shaped main body 190 and the cover body are inserted. This is for engaging with 210. Note that the engagement between the engagement protrusion 217 and the engagement step groove 195 and the action of the protrusion piece 208 will be described in detail later.

  In addition, a rail installation part 235 on the rail is provided along a predetermined side outside the lateral side walls of the box-shaped main body 190, and a slide sealing member 220 that can slide only in one direction is provided on the rail installation part 235. It is provided so that it cannot be removed. Although the slide seal member 220 will be described later, the slide seal member 220 includes a plate-shaped portion 221 that is formed of, for example, an opaque resin and protrudes toward the box-shaped main body 190. Cutout portions 222 are formed at a plurality of locations, and a slide excision portion 223 projecting outward from the outer surface of the plate-like portion 221 is provided between the plurality of cutout portions 222 in an artificially excisable state. Yes. The plate-like portion 221 has a predetermined space between the plate-like portion 221 and the rail extending portion 235 above the rail extending portion 235 in the depth direction (for example, a space in which an opening preventing protrusion 245 described later can enter). It protrudes in the position which has.

  The slide sealing member 220 is a fixing means for preventing the box-shaped main body 190 and the cover body 210 from being separated from each other, and will be described later, which is formed to protrude from the cover body 210 when the box-shaped main body 190 and the cover body 210 are combined. By inserting the opening prevention protrusion 245 from the notch 222 formed in the plate-like portion 221 of the slide sealing member 220, the opening prevention protrusion 245 slides the slide sealing member 220 after being positioned below the plate-like portion 221. The box-shaped main body 190 and the cover body 210 are brought into a sealed state in which the box-shaped main body 190 and the cover body 210 cannot be removed by sliding the sealing member 220 to a position covered by the plate-like portion 221 that is not the notch 222. That is, even if the box-shaped main body 190 and the cover body 210 are to be removed in the sealed state, the opening prevention protrusion 245 positioned below the plate-shaped portion 221 contacts the lower side surface of the plate-shaped portion 221 of the slide sealing member 220. The sealed state between the box-shaped main body 190 and the cover body 210 cannot be released.

  Further, engaging projections 205 project outwardly from the upper and lower portions of both side walls in the vertical direction of the box-shaped main body 190, and are locked so as to be parallel to the side walls at substantially the center of the other side wall in the vertical direction. A lever 206 is formed. The engagement protrusion 205 is engaged with an engagement hole 257 formed in the mounting base 250 to be described later, and the locking lever 206 is locked in a locking hole 259 of the mounting base 250. . Therefore, a locking claw 207 is formed at the lower end of the locking lever 206. That is, the engagement protrusion 205 and the locking lever 206 are members for detachably attaching the main board box 150 to the attachment base 250.

  As shown in FIG. 5, the main board 151 mounted on the box-shaped main body 190 configured as described above is constituted by a rectangular printed wiring board, and most of its upper surface contains RAM and ROM. CPU 243 (CPU, RAM, ROM may be separately formed as a chip or a one-chip microcomputer), which is a so-called one-chip microcomputer formed into a single chip, and electronic components such as transistors and resistors are mounted. On the other hand, regions on both sides in the vertical direction are formed as connector mounting regions for mounting the plurality of connectors 151a to 151i. In addition, positioning holes 240 and mounting holes 241 are formed in the four corners of the main board 151, and as described above, the positioning protrusions 192 and the mounting bosses 193 projecting from the inner four corners of the bottom plate 191 of the box-shaped main body 190 are formed. It is fixed by an engagement or conductive screw 242.

  The mounting hole 241 is formed in a portion where the ground line of the main board 151 is printed. When the conductive screw 242 is fixed, the ground line and the conductive screw 242 are electrically connected. The conductive screw 242 has a flat tip contact surface at the tip, and the tip is exposed to the back side of the bottom plate 191 when the main board 151 is fixed to the mounting hole 241. Therefore, as will be described in detail later, when the main board box 150 is mounted on the mounting base 250, it comes into pressure contact with the elastic contact piece 261 of the mounting base 250.

  As described above, the cover body 210 as a lid body that covers the mounting surface side of the main substrate 151 supported by the box-shaped main body 190 is formed in a box shape with the bottom open, and both the side wall plates 211 in the vertical direction in the figure and Heat dissipation holes 214 are formed above and below the top plate. In addition, a pattern covering plate 212 as a cover plate in which a connector through hole 213 as an opening is formed protrudes outward from the lower ends of both side wall plates 211 (the side in contact with the main board 151). . Since the connector through hole 213 is formed in substantially the same size as each of the connectors 151a to 151i mounted on the main board 151, only the connectors 151a to 151i pass through the connector through hole 213 and are connected to the connectors 151a to 151i. The periphery of 151a to 151i is covered with a pattern covering plate 212. As a result, the wiring patterns around the connectors 151a to 151i are completely covered. Therefore, it is possible to prevent unauthorized wiring from being soldered to the wiring patterns around the connectors 151a to 151i. Foreign matter including wiring cannot be inserted from between the substrate 151 and the cover body 210, and any illegal action on the main substrate 151 cannot be performed anyway.

  In addition, the upper surface plate of the cover body 210 has the heat radiation holes 214 formed in the upper and lower sides as described above, and is written when the model name sticker attaching portion 215 for attaching the model name sticker therebetween and the main board 151 are inspected. A history sticker pasting portion 216 for pasting a history sticker describing items of “inspector” and “inspection date” is formed.

  On the other hand, the notch portion formed in the plate-like portion 221 of the slide sealing member 220 described above when the box-shaped main body 190 and the cover body 210 are combined is provided at the approximate center of the upper and lower side wall plates in the horizontal direction of the cover body 210 in the figure. An anti-opening protrusion 245 that is inserted through 222 and positioned below the plate-like portion 221; and an anti-slide protrusion 246 that is positioned above the plate-like portion 221 when the box-shaped main body 190 and the cover body 210 are combined. Is provided. The slide prevention protrusion 246 abuts on the slide excision part 223 described above by sliding the slide seal member 220 and restricts the slide of the slide seal member 220.

  Further, an L-shaped engagement protrusion 217 is formed on one side end of the upper side wall plate in the illustrated horizontal direction of the cover body 210 and one side end of the lower side wall plate facing the one side end of the upper side wall plate. Is protruded outward, and the engaging protrusion 217 is dropped into the engaging step groove 195 of the box-shaped main body 190. More specifically, as shown in FIG. 7A, the engaging protrusion 217 is formed by a vertical piece 217b in the vertical width direction and a horizontal piece 217a in the horizontal width direction on the upper and lower side walls of the cover body 210. It is L-shaped.

  Further, the first step groove 195a of the engagement step groove 195 described above has a lateral width dimension at the entrance thereof that is slightly larger than the horizontal piece 217a, and the dimension in the depth direction thereof is the same as that of the first step groove 195a. When the horizontal piece 217a is brought into contact with the bottom surface, the pattern covering plate 212 is located at a position higher than the upper ends of the connectors 151a to 151i and is not obstructed by the member of the box-shaped main body 190 constituting the engagement step groove 195. It is a dimension that can slide horizontally. The width of the second step groove 195b is substantially the same as that of the horizontal piece 217a, and the height dimension is such that the back surface of the pattern covering plate 212 is in contact with the upper surface of the main substrate 151. The height of the vertical piece 217b does not protrude from the upper end of the first step groove 195a. In the second step groove 195b shown in FIG. 7A, a notch 195c is formed slightly above the main substrate 151. However, the notch 195c is not necessarily required.

  7B, the horizontal piece 217a of the engagement protrusion 217 is dropped into the first step groove 195a of the engagement step groove 195 and brought into contact with the bottom surface of the first step groove 195a. In the abutted state, the pattern covering plate 212 is stopped at a position above the connectors 151 a to 151 i of the main board 151. Thereafter, as shown in FIG. 7C, by sliding the horizontal piece 217a in the left lateral direction, the horizontal piece 217a is dropped into the second step groove 195b and at the same time the connector through hole 213 of the pattern covering plate 212 is formed. It is dropped so as to penetrate from directly above the connectors 151a to 151i. Thereby, the cover body 210 can be attached to the box-shaped main body 190. At this time, the vertical piece 217b of the engagement protrusion 217 closes the communication portion between the first step groove 195a and the second step groove 195b. It cannot be invaded. Conversely, when removing the cover body 210, the cover body 210 can be easily removed by lifting it upward, sliding it to the right, and further lifting it.

  However, as a premise that the cover body 210 can be separated from the box-shaped main body 190, it is necessary that the above-described notch portion 222 is provided at a position where the opening prevention protrusion 245 provided on the cover body 210 can be inserted. Accordingly, the slide sealing member 220 is moved until the release prevention protrusion 245 located below the plate-like portion 221 that is not the notch 222 of the slide sealing member 220 is located below the notch 222 formed on the plate-like portion 221. It is necessary to slide so that the position of the notch portion 222 is a position where the opening prevention protrusion 245 can be inserted.

  At this time, in a state where the box-shaped main body 190 and the cover body 210 are combined, a position where the opening prevention protrusion 245 cannot pass through the notch 222, that is, a plate where the opening prevention protrusion 245 is not the notch 222 of the slide seal member 220. When the slide sealing member 220 is to be slid, the slide cutout 223 projecting outward from the outer surface of the plate-like part 221 and the slide body 210 are prevented from sliding. The slide sealing member 220 cannot be slid by contact with the protrusion 246. In this embodiment, the slide sealing member 220 is made slidable by cutting out the slide cutting portion 223, and the slide sealing member 220 is moved until the position of the notch 222 reaches the position where the opening prevention protrusion 245 can be inserted. As a result, the cover body 210 can be separated from the box-shaped main body 190 (openable state).

  In this embodiment, the slide prevention protrusion 246 is formed to protrude from the cover body 210. However, the slide prevention protrusion 246 may be formed to protrude from the box-shaped main body 190. In this case, the slide sealing member 220 is slid so as to restrict the position of the notch 222 to the position where the opening prevention protrusion 245 can be inserted (for example, the slide excision projecting from the plate-like portion 221). The anti-sliding protrusion 246 is formed to protrude at a position where it abuts the portion 223. However, as in this embodiment, the slide prevention projection 246 is formed to protrude from the cover body 210, and the release prevention projection 245 and the slide prevention projection 246 are positioned close to each other to prevent the slide sealing member 220 from being opened during operation. The positional relationship among the protrusion 245, the slide prevention protrusion 246, the notch 222, and the slide excision 223 can be easily grasped, and workability is improved.

  Further, in this embodiment, the slide excision part 223 is formed so as to protrude at a position close to the box-shaped main body 190 of the plate-like part 221 of the slide sealing member 220, and overlaps the notch part 222 in the thickness direction of the slide sealing member 220. However, the position where the protrusion is formed is not limited to this example, and it protrudes to any position as long as it is located outside the plate-like portion 221 of the slide sealing member 220 and between the notches 222 in the sliding direction. It may be formed. For example, the slide excision 223 may be formed so as to protrude at a position far from the box-shaped main body 190 outside the plate-like portion 221 of the slide seal member 220 so as not to overlap the notch 222 in the thickness direction of the slide seal member 220. In this case, when the cover body 210 and the box-shaped main body 190 are combined, the side surface of the slide prevention protrusion 246 that projects from the cover body 210 (the surface that does not face the side surface of the cover body 210) and the slide cutout portion 223. What is necessary is just to comprise so that the slide prevention protrusion 246 of the magnitude | size which the side surface (surface which does not oppose the outer side of the plate-shaped part 221 of the slide sealing member 220) contact | abuts may be formed.

  Further, even if the cover body 210 is forcibly lifted from both side wall plates 211 in the illustrated vertical direction to create a gap and try to tamper with it, the horizontal piece 217a contacts the upper surface inside the second step groove 195b, and the contact Even if it is attempted to insert a foreign substance from the side in this state, it cannot be inserted from the side of the main board box 150 by the side wall plate 211, so that it is possible to reliably prevent fraud. In addition, by providing an engagement portion by the engagement protrusion piece 217 and the engagement step groove 195 as described above, the fastening portion (for example, the slide seal member 220 and the release prevention protrusion 245) to be finally attached is provided. Since the number of installations can be reduced, the cost can be reduced and the assembling work is facilitated.

  In the state in which the box-shaped main body 190 opened at the upper side and the cover body 210 opened at the lower side are closed as described above, the entire peripheral side wall of the box-shaped main body 190 and the entire peripheral side wall of the cover body 210 are on the side. It is designed to overlap as seen from the side. This means that a gap is not formed between the box-shaped main body 190 and the cover body 210 when viewed from the side, and a gap is generated between the box-shaped main body 190 and the cover body 210. When viewed from the back side of the cover body 210 (when viewed from the right to the left in FIG. 5), in this case, since it is perpendicular to the main board 151, the box-shaped main body 190 and the cover body are temporarily Even if a thin wire-like foreign object is to be inserted through the gap with 210, it is not possible to reach an electronic component mounted inside the main board 151 unless the foreign object is bent at a right angle. The board box 150 has an advantage that it is difficult to cheat.

  Here, the slide sealing member 220 provided in the main board box 150 comprised as mentioned above is demonstrated. FIG. 8A is a cross-sectional view of the slide sealing member 220 as viewed from the front, the side, and the top in a state where the slide sealing member 220 is not attached to the box-shaped main body 190, and FIG. It is sectional drawing seen from the side in the state attached to the box-shaped main body 190. FIG.

  As shown in FIG. 8 (A), a rail installation part 235 protrudes from the outer surface of the box-shaped main body 190, and the tip of the rail installation part 235 (portion far from the outer surface of the box-shaped main body 190). The upper protrusion 236 and the lower protrusion 237 are formed as protrusions divided into upper and lower parts. That is, the upper end protrusion 236 and the lower protrusion 237 that protrude on both the upper and lower sides are provided at the front end portion (the portion far from the box-shaped main body 190) of the rail extending portion 235 so as to face the outer surface of the box-shaped main body 190. . Further, the slide seal member 220 is configured by a hollow member having a hollow portion that can be inserted through the upper protrusion 236 and the lower protrusion 237. When the slide sealing member 220 is attached to the box-shaped main body 190, the upper protrusion 236 and the lower protrusion 237 that protrude from the side of the slide sealing member 220 to the rail installation portion 235 are inserted. At this time, the upper protrusion 236 and the lower protrusion 237 are engaged with the inner surface of the hollow portion of the slide sealing member 220 formed in a hollow shape, so that the slide sealing member 220 is attached to the outer surface of the box-shaped main body 190. It is provided so that it cannot be removed from the rail extending portion 235 provided along the predetermined side.

  In addition, the slide sealing member 220 can be slid only in one direction on the side surface that faces the outer surface of the box-shaped main body 190 of the rail installation portion 235 and contacts the inner side of the hollow portion of the slide sealing member 220. A retrograde hook 238 is provided so as to protrude. In this embodiment, it is formed so as to protrude from a predetermined position on the side surface of the rail extending portion 235 so as to have a predetermined angle with respect to the slidable direction of the slide sealing member 220. In addition, a bending groove 239 is formed on the side of the anti-reverse hook 238 projecting from the rail 235 so as to allow the slide seal member 220 to slide. When it comes into contact with the retrograde protrusion 224 formed on the side surface, it is distorted in the inner direction of the flexible groove 239.

  In addition, the rail extending portion 235 is formed of, for example, an opaque resin (not necessarily opaque), and the anti-reverse hook 238 protruding from the rail extending portion 235 has the same material, and therefore has elasticity. In addition, the distortion in the inner direction of the flexure groove 239 in contact with the retrograde prevention protrusion 224 causes stress in the outward direction of the flexure groove 239 (the direction of the retrograde prevention projection 224 in contact with the retrograde prevention hook 238). Thus, the force to return to the original shape works. The anti-reverse hook 238 engages with an anti-reverse protrusion 224, which will be described later, and allows the slide seal member 220 to slide only in one direction.

  A plurality of anti-reverse protrusions 224 are formed on the inner side surface of the hollow portion of the slide seal member 220 so that the slide seal member 220 can slide in only one direction. In this embodiment, the retrograde prevention protrusion 224 protrudes across the width direction of the slide sealing member 220 on the inner surface facing the outer surface of the box-shaped main body 190, so that the slide sealing member 220 can slide. It has a gentle inclination (for example, a gentle inclination of, for example, about 15 ° with respect to the outer surface of the box-shaped main body 190) and a sharp inclination (for example, a box with respect to the non-slidable direction of the slide sealing member 220). For example, a steep inclination of about 90 ° with respect to the outer surface of the main body 190. In addition, by attaching the slide sealing member 220 to the rail side portion 235 of the box-shaped main body 190, the retrograde hook 238 protruding from the side surface of the rail side portion 235 and the inner side surface of the hollow portion of the slide sealing member 220 are formed. The anti-reverse protrusion 224 is brought into contact with the slide seal member 220 so that the slide seal member 220 can be slid only in a direction in which the anti-reverse protrusion 224 has a gentle inclination.

  The anti-reverse hook 238 has a gentle inclination with respect to the slidable direction of the slide sealing member 220 of the anti-reverse protrusion 224 and a sharp inclination with respect to the non-slidable direction of the slide sealing member 220. When the slide sealing member 220 is fixed by engaging with a surface having a steep slope located between the surface and the back surface, the anti-reverse hook 238 is bent by the flexible groove 239 when the slide sealing member 220 is slid in this state. The anti-reverse protrusion 224 is distorted in the direction of entering and moves in contact with the gently inclined surface of the anti-reverse protrusion 224. After reaching the apex of the anti-reverse protrusion 224, the slide seal member 220 is further made the same. By sliding in the direction, the anti-reverse protrusion 224 to be formed next moves between a surface having a steep slope and a surface having a gentle slope. At the same time, it returns to its original shape due to the stress generated in the state of being distorted in the direction of entering the inner side of the flexure groove 239, and in the direction in which the slide sealing member 220 of the retrograde prevention projection 224 formed next cannot slide On the other hand, the slide seal member 220 is engaged with a surface having a steep inclination to restrict the slide seal member 220 from sliding in the reverse direction, and the slide seal member 220 can be slid only in one direction.

  Further, in this embodiment, the retrograde prevention protrusion 224 that allows the slide seal member 220 to slide in only one direction protrudes from the inner side surface of the hollow portion of the slide seal member 220 facing the box-shaped main body 190. The position for forming the retrograde preventing protrusion 224 may be anywhere as long as it is in contact with the rail extending portion 235. In this case, the retrograde prevention hook 238 may be provided on the side surface of the rail extending portion 235 that contacts the retrograde prevention projection 224. For example, the anti-reverse protrusion 224 protrudes from the upper inner surface and / or the lower inner surface of the hollow portion of the slide seal member 220, and the upper surface of the upper protrusion 236 and / or the lower surface of the lower protrusion 237 Alternatively, the retrograde prevention hook 238 may be provided so as to project.

  Also, a retrograde prevention projection 224 projecting from the inner side surface of the hollow portion of the slide seal member 220, and a retrograde prevention hook 238 projecting from the side surface of the rail installation portion 235 facing the outer side surface of the box-shaped main body 190, The slide sealing member 220 is restricted from sliding freely by being locked. That is, in a state where the slide sealing member 220 is not pressed in the slidable direction, a surface having a gentle inclination with respect to the slidable direction of the anti-reverse hook 238 and a sharp inclination with respect to the non-slidable direction. The anti-reverse hook 238 is located between the surface and the surface having a gentle inclination with respect to the slidable direction of the anti-reverse hook 238, and the surface having a sharp inclination with respect to the non-slidable direction, By forming an engagement state between the two surfaces, the slide sealing member 220 is restricted from sliding freely. In this embodiment, the anti-reverse protrusion 224 includes an anti-reverse hook 238 when any one of the plurality of notches 222 formed on the plate-like portion 221 of the slide seal member 220 is in a predetermined position. It is formed so as to be able to engage and stop the slide of the slide sealing member 220. For example, when the notch portion 222 is positioned above the opening prevention protrusion 245 and the opening prevention protrusion 245 reaches the insertion possible position where the notch portion 222 can be inserted, the slide sealing member of the retrograde prevention protrusion 224 can slide. The anti-reverse hook 238 is positioned between the surface having a gentle inclination with respect to the direction and the surface having an abrupt inclination with respect to the non-slidable direction so as to form an engagement state. A retrograde prevention protrusion 224 is formed.

  In addition, notches 222 are formed at a plurality of locations on the plate-like portion 221 protruding from the slide seal member 220 toward the outer surface of the box-shaped main body 190. In this embodiment, as shown in FIG. 8A, four notches 222 are formed in the plate-like portion 221 of the slide sealing member 220 so as to have the same interval. Further, between each notch portion 222, an artificially excisable slide excision portion 223 projecting outward from the outer surface of the plate-like portion 221 of the slide seal member 220 is provided. Further, the slide excision portion 223 is formed with markings “1” to “4” in order from the slidable direction of the slide sealing member 220 on the surface thereof. As described above, in this embodiment, the slide sealing member 220 is attached to the box-shaped main body 190 so as to be slidable only in one direction. In this embodiment, as shown in FIGS. 8 (A) and 9 (A), the anti-reverse hook 238 and the anti-reverse protrusion 224 so that the slide sealing member 220 can be slid only in the left direction in the figure. Is formed, and a slide excision 223 protrudes from the cutout 222 on the side in which the slide seal member 220 can slide. That is, a notch 222 is formed between each plate-like part 221 on which the slide cutout part 223 is projected. For example, a plate-like part 221 on which a slide excision part 223 formed with an inscription “1” is protruded, a plate-like part 221 on which a slide excision part 223 formed with an inscription “2” is provided, A notch 222 is formed in between, and the notch 222 can be inserted into the opening prevention protrusion 245 when the slide sealing member 220 is slid after the slide excision 223 with the mark “1” is cut. It will be a possible insertion position.

  Further, as shown in FIG. 8A, the above-described slide prevention protrusion 246 protrudes above the opening prevention protrusion 245 provided on the cover body 210. Further, as shown in FIG. 8B, when the box-shaped main body 190 and the cover body 210 are combined, the release prevention protrusion 245 protrudes from the slide sealing member 220 toward the outer surface of the box-shaped main body 190. The slide prevention protrusions 246 are provided so as to protrude below the plate-like portion 221 at positions below the plate-like portion 221. Further, as shown in FIG. 9A, the opening prevention protrusions 245 and the slide prevention protrusions 246 are protruded so that the positions in the width direction of the cover body 210 (the left-right direction in FIG. 9A) are different. That is, if the opening prevention protrusion 245 and the slide prevention protrusion 246 are protruded so that the positions in the width direction of the cover body 210 are the same, the slide sealing member 220 is slid so that the notch 222 is positioned at the insertable position. Sometimes the opening prevention protrusion 245 cannot be visually recognized from the notch 222. Therefore, the opening prevention protrusion 245 and the slide prevention protrusion 246 are inserted through the notch 222 when the opening prevention protrusion 245 can be visually recognized from the notch 222 by changing the positions of the cover body 210 in the width direction as in the present embodiment. The position can be set to the possible position, and the opening operation of the box-shaped main body 190 and the cover body 210 is facilitated.

  When the main board box 150 is opened for inspection of the main board 151 (inspection of whether the ROM is genuine after delivery) at a game arcade or the like, the slide sealing member 220 is slid and the opening prevention protrusion 245 is provided. A position where the opening prevention protrusion 245 can be inserted through the notch 222 in a sealed state covered by a portion other than the notch 222 of the plate-like part 221 protruding from the slide sealing member 220 toward the outer surface of the box-shaped main body 190. Even if the slide seal member 220 is to be slid, the slide cutout portion 223 protruding from the upper portion of the plate-like portion 221 and the slide prevention protrusion 246 protruding from the outer surface of the cover body 210 come into contact with each other and the slide seal member 220 additional slides are regulated. However, the cross-sectional shape of the slide excision 223 projecting from the plate-like portion 221 is formed to be thinner than other portions on the side close to the plate-like portion 221 as shown in FIG. Can be resected. For example, by pressing in the horizontal direction shown in FIG. 8A, the stress is concentrated on the base of the slide excision 223 (the side close to the plate-like part 221 of the slide sealing member 220, and the slide excision 223 is folded from the base. In this manner, the slide sealing member 220 is moved until the restriction is released by cutting the slide cutting portion 223 that is in contact with the slide preventing projection 246 so that the opening preventing projection 245 can be inserted through the notch 222. That is, the box-shaped main body 190 and the cover body 210 can be separated.

  In this embodiment, by making the part about 1 to 2 mm from the base of the slide excision part 223 thinner than the other part and making the outer side thicker than the base part, the slide excision part 223 has a cross-sectional shape. The slide excision part 223 is configured so that stress is concentrated on the narrow base part when the slide excision part 223 is pressed from the side, and the base part can be easily folded. However, the cross-sectional shape of the slide excision part 223 is not limited thereto. It is only necessary that it can be excised artificially. For example, by making the cross-sectional shape of the slide excision part 223 widen from the side close to the plate-like part 221 toward the outside (the side far from the plate-like part 221), the base part (plate-like) of the slide excision part 223 is obtained. The side close to the portion 221 may be formed thinner than the other portions, and the stress may be concentrated at the root portion when pressed from the side.

  Moreover, in this embodiment, it has the weak part 225 formed so that one part of the slide sealing member 220 might become thin compared with another part. Since the fragile portion 225 is formed to be thinner than the other portions, the slide sealing member 220 can be cut. By cutting the fragile portion 225 of the slide sealing member 220, the upper protrusion 236 and the lower side of the rail installation portion 235 The engagement state between the protrusion 237 and the inner side surface of the hollow portion of the slide seal member 220 can be easily released. That is, it becomes easy to remove the slide seal member 220 from the rail installation portion 235, and the main board box 150 can be reused by exchanging the slide seal member 220, and the replacement work of the slide seal member 220 is facilitated.

  Further, when the box-shaped main body 190 and the cover body 210 are combined, the slide sealing member 220 is inserted from the side of the rail installation portion 235 in a state where the box-shaped main body 190 and the cover body 210 are combined. The operation of locking the box-shaped main body 190 and the cover body 210 is performed. Then, by sliding the slide sealing member 220, the box-shaped main body 190, the cover body 210, The main substrate 151 can be sealed by the main substrate box 150.

  That is, as shown in FIG. 9, in a state where the box-shaped main body 190 and the cover body 210 are combined (FIG. 9A), the side of the rail installation portion 235 (in this example, the rail installation portion). The slide sealing member 220 is inserted from the right side of 235, and the upper protrusion 236 and the lower protrusion 237 are inserted into the hollow portion of the slide sealing member 220 (FIG. 9B). Then, the slide sealing member until the release preventing projection 245 is positioned below the plate-like portion 221 projecting from the slide sealing member 220 toward the outer surface of the box-shaped main body 190 (in the rearward direction in FIG. 9C). 220 is slid in a slidable direction (in this embodiment, in the left direction in FIG. 9C). Even if it is intended to separate the box-shaped main body 190 and the cover body 210 by sliding the slide sealing member 220 until the opening prevention protrusion 245 is positioned below the plate-like part 221, the opening prevention protrusion 245 is the lower side of the plate-like part 221 Is brought into a sealed state that cannot be opened (FIG. 9C).

  In FIG. 9C, the slide sealing portion 223 protruding from the plate-like portion 221 of the slide sealing member 220 and the slide prevention protrusion 246 protruding from the outer surface of the cover body 210 are in a position where they slide. When the member 220 is stopped, even if the slide sealing member 220 is further slid in the slidable direction, that is, in the left direction in the figure, the slide cutting portion 223 and the slide preventing protrusion 246 are engaged, and the slide sealing is performed. The member 220 cannot be slid. Therefore, the slide sealing member 220 can be slidable by releasing the locking state between the slide preventing projection 246 and the slide cutting portion 223 by cutting the slide cutting portion 223 that contacts the slide preventing projection 246. Yes (FIG. 9D). In FIG. 9, the slide excision part 223 formed with the inscription “1” in contact with the slide prevention protrusion 246 in FIG. 9C is excised in FIG. The engagement state between the slide excision part 223 formed with slidable and the slide prevention protrusion 246 is released, and the slide seal member 220 is made slidable. By removing the slide excision part 223 in which the mark “1” is formed, the slidable direction side of the plate-like part 221 projecting from the slide excision part 223 in which the mark “2” is formed (FIG. 9 ( In D), the notch 222 located in the left direction in the figure) can be moved to the insertable position.

  Then, the slide sealing member 220 is slid in a slidable direction so that the notch 222 is positioned above the opening prevention protrusion 245 (on the front side in FIG. 9E), and the opening prevention protrusion from the notch 222. By making 245 a visible insertion-possible position, the box-shaped main body 190 and the cover body 210 can be separated. That is, the cover body 210 is lifted upward (frontward in the figure in FIG. 9E) to allow the opening prevention protrusion 245 to be inserted from the notch 222 and above the plate-like part 221 (illustrated in FIG. 9E). By being positioned in the forward direction), an engagement state between the release preventing projection 245 and a portion that is not the notch 222 of the plate-like portion 221 projecting from the slide sealing member 220 toward the outer surface of the box-shaped main body 190 Is released, and the box-shaped main body 190 and the cover body 210 are separable from each other.

  Further, as described above, in this embodiment, the slide sealing member 220 is stopped when the slide sealing member 220 is slid and the notch 222 is in a predetermined position. That is, in FIG. 9C, a sealing state in which the opening prevention protrusion 245 is located below (backward) the portion that is not the notch 222 of the plate-like portion 221, and the plate-like portion 221 in FIG. 9E. The size is such that the slide sealing member 220 is stopped in an openable state in which the opening prevention protrusion 245 is positioned below (in the back) of the notch 222 formed at the bottom and the opening prevention protrusion 245 is visible from the notch 222. Is formed. With this configuration, it is possible to easily remove the box-shaped main body 190 and the cover body 210 in an openable state.

  Further, after the slide excision portion 223 having the mark “1” formed thereon is excised, the slide seal member 220 is stopped at the position shown in FIG. 9E without sliding, and the box-shaped main body 190 and the cover body 210 are again connected. The slide prevention member 245 is inserted through the notch 222 located on the left side of the plate-like portion 221 on which the slide excision 223 formed with the stamp “2” is formed when combined, and then the slide seal member 220 is shown. By sliding to the left, the opening prevention protrusion 245 is in a sealed state covered with a portion other than the notch 222 of the plate-like portion 221. Thereafter, in the case where the opening is possible again, the slide excision part 223 on which the “2” stamp is formed is cut out so that the slide sealing member 220 is slidable, and the slide on which the “3” stamp is formed. The box-shaped main body 190 and the cover body 210 can be separated into an openable state by moving the notch 222 located on the left side of the plate-shaped portion 221 on which the cut-out portion 223 protrudes to the insertable position. .

  In this embodiment, when the box-shaped main body 190 and the cover body 210 are put into a separable openable state, the slide-cut section 223 formed with a small number of marks is cut out in order, The slide seal member 220 can be stopped at a position where the slide cutout 223 is not cut on the plate-like portion 221 located above the prevention protrusion 245 (the front side in FIG. 9C). For example, the order in which the slide excision part 223 is excised is not limited. However, the number of times of excision of the slide excision part 223, that is, the number of times of separation between the box-shaped main body 190 and the cover body 210 can be clarified by excising the slide excision part 223 in the order according to the marking, and the box-like After the main body 190 and the cover body 210 are combined, the opening prevention protrusion 245 is inserted through the notch 222 and positioned below the plate-like portion 221 of the slide sealing member 220 (backward in FIG. 9E). The same operation (for example, the slide seal member 220 is engaged only once (the anti-reverse hook 238 engaged with the anti-reverse protrusion 224 is engaged with the next anti-reverse protrusion 224 by sliding the slide seal member 220). Since the slide) may be performed, the operation of opening and sealing the main board box 150 is facilitated.

  After separating the box-shaped main body 190 and the cover body 210 in this manner, the opening-preventing protrusion 245 is inserted through the notch 222 again, and the slide sealing member 220 is slid in the slidable direction to The cover body 210 can be sealed. In this embodiment, the plate-like portion 221 protruding from the slide sealing member 220 toward the outer surface of the box-shaped main body 190 has four slide cut-out portions 223 and four slide cut-out portions alternately. Is provided. 9A to 9E, the box-shaped main body 190 and the cover body 210 are separated from each other, and then the box-shaped main body 190 and the cover body 210 are combined to form a sealed state again. Is performed four times, so that the entire slide excision part 223 is excised, and the slide of the slide seal member 220 cannot be regulated. That is, the box-shaped main body 190 and the cover body 210 cannot be sealed.

  Note that it is possible to easily increase the number of slide excision portions 223 and notches 222 projecting from the plate-like portion 221 of the slide seal member 220. At that time, the number of the retrograde prevention protrusions 224 provided on the slide sealing member 220 is twice the number of the notches 222 and the slide cutouts 223, and the positions where the opening prevention protrusions 245 can be inserted into the notches 222. What is necessary is just to arrange | position in the position which can stop the slide sealing member 220 in the position which cannot be inserted.

  Further, since the slide seal member 220 is formed separately from the box-shaped main body 190 and the cover body 210, the weak portion 225 of the slide seal member 220 is removed from the rail side portion 235 by cutting with a tool such as a nipper, The box-shaped main body 190 and the cover body 210 can be reused by inserting a new slide seal member 220 from the non-slidable side of the rail installation portion 235 (the right side in FIG. 9A).

  In this embodiment, one side end of the rail extending portion 235 is configured to contact the protruding piece portion 208, and the slide sealing member 220 is cut by cutting the weak portion 225 of the slide sealing member 220. The main board box 150 is arranged so that the slide sealing member 220 can be removed from one end of the rail extending portion 235 without cutting the slide sealing member 220. It may be configured. For example, by forming the protruding piece portion 208, the forward protruding piece 209, and the engaging protruding piece 217 so as to protrude inward from the inner surface of the main board box 150, both side ends of the rail extending portion 235 are opened. Further, the upper protrusion 236 and the lower protrusion 237 of the rail extending portion 235 or the rail extending portion 235 may not be formed from a predetermined position, that is, “4” of the slide sealing member 220. The slide sealing member 220 is slid after the slide excision portion 223 formed with the mark "" is formed, and the position where the notch 222 reaches the openable position (position where the slide sealing member 220 abuts against the protruding piece 208) By configuring so that the upper projection 236 and the lower projection 237 of the rail side portion 235 or the rail side portion 235 is not formed, The ride seal member 220 can be slid in the slidable direction of the rail installation portion 235 and can be removed from one end of the rail installation portion 235, and a tool such as a nipper is required to replace the slide seal member 220. Does not make the work easier.

  Further, in the sealed state of the main board box 150, the main board box 150 cannot be opened unless a predetermined portion of the slide sealing member 220 (the slide cutting portion 223 in this embodiment) is cut out. Yes. Therefore, when the slide excision part 223 is excised other than the inspection of the main board 151, it is possible to immediately and reliably determine that the main board 151 has been cheated by this excision. The crime prevention effect can be enhanced.

  In this embodiment, the rail extending portion 235 is formed so as to protrude from the outer surface of the box-shaped main body 190 and is integrally formed with the box-shaped main body 190, but only in one direction from the inside of the box-shaped main body 190. The rail extending portion 235 may be configured to be screwed to the box-shaped main body 190 with a one-way screw that is configured to be rotatable and cannot be removed. In this case, it is desirable that a positioning projection and a positioning hole are provided at a position where the rail extending portion 235 is attached, and screwed after positioning. With this configuration, the box-shaped main body 190 can be easily molded.

  In this embodiment, the rail-shaped portion 235 protrudes from the box-shaped main body 190 and the slide sealing member 220 is attached to the box-shaped main body 190. The slide sealing member 220 may be configured to be attached to the cover body 210 by projecting from the cover body 210. In this case, the opening prevention protrusion 245 and / or the slide prevention protrusion 246 may be configured to protrude from the box-shaped main body 190. However, the provision of the rail extending portion 235 on the box-shaped main body 190 as in this embodiment has the following advantages. That is, generally, the box-shaped main body 190 that supports the main board 151 is thicker (depth) than the cover body 210 to accommodate the board on which an IC or the like is mounted, and the slide sealing member 220 is attached. Further, it is not necessary to further increase the thickness in accordance with the size (outer diameter) of the slide sealing member 220. Therefore, the main board box 150 can be molded without increasing the thickness of the main board box 150 by attaching the slide sealing member 220 to the box-shaped main body 190.

  Further, in the above-described embodiment, as the board storage box, the board containing the main board 151 for controlling the game operation is shown, but other control boards, for example, the lamp driver board 80, the audio output board 82, the payout control board. 36, the configuration of the present invention may be applied to a substrate box that accommodates the power supply unit substrate 137 and the like. The board storage box only needs to cover the entire area of the circuit board other than the connector (for example, electronic component mounting surface, solder surface, connector pattern surface) with the main body and the lid. An extremely small opening with a clearance or a heat radiation hole may be formed. Therefore, even if a part of the ground line other than the connector and a part of the substrate on which no pattern is formed are exposed to the outside from the box, it is sufficient that the essential data line pattern and mounting parts are not exposed. The number of connectors provided on the circuit board accommodated in the board accommodation box may be one or more.
