It is screwed into a screw hole (not shown) provided in the back plate 11c. Further, after positioning and holding the movable base portion 203 in the standing posture state, the window portion of the reinforcing plate 240, the opening hole portion 238 of the movable base portion 203, the opening hole 216 of the fixed base portion 203, the frame from the front of the housing 11 A fixing screw is inserted into the insertion hole 215 d of the member 215, and the fixing screw is screwed into a screw hole portion (not shown) provided in the back plate 11 c of the housing 11. In addition, a fixing screw is inserted from the rear of the housing 11 into an insertion hole (not shown) formed in the back plate 11 c of the housing 11 in advance, and the fixing screw is inserted into the second mounting flange of the fixing base portion 203. The screw hole 214c formed in the part 214 is screwed. By performing the above operation, the pedestal device 201 is fixed to the back plate 11c of the housing 11 with fixing screws from both front and rear directions.

  Next, an operation for mounting the main control device 101 to the base device 201 will be described.

  When the main control device 101 is mounted on the pedestal device 201, the main control device 101 is inserted from above the movable base portion 203, and the box case 131 of the main control device 101 is moved along the back plate portion 231 of the movable base portion 203. Then, it is slid to the bottom plate portion 232 side. When the main controller 101 is placed on the bottom plate portion 232 (reinforcing plate 240), the back plate portion 231 of the movable base portion 203 is formed in the through hole 145a formed in the overhang plate portion 145 of the box case 131. The protruding portion 253 is inserted, and the protrusion 146 (see FIG. 10) formed on the rear surface of the box case 131 is inserted into the through hole 252a formed in the locking portion 252 of the movable base portion 203. As a result, the main control device 101 is restricted from moving in the front-rear direction by the back plate portion 231 and the return plate portion 245, is restricted from moving in the left-right direction by the side wall portion 233, and is moved downward by the bottom plate portion 232. In addition to being restricted, movement in the front-rear direction and the left-right direction is restricted by the engagement of the protrusion 253 and the through-hole 145a, and movement in the up-and-down direction is restricted by the engagement of the protrusion 146 and the through-hole 252a. Thus, the movable base 203 is held. Thereafter, the fixing screw 251 is inserted from the front surface side of the movable base portion 203 into the insertion hole 250a formed in the front wall portion 250 of the movable base portion 203, and is formed in the second recess 114 of the main controller 101. The main control device 101 is fixed to the movable base 203 by being screwed into the screw hole.

  After fixing the main controller 101 to the movable base 203, the main controller 101 and the movable base 203 are sealed.

  Specifically, a sealing seal (not shown) is provided so as to cover the fixing screw 251 and the insertion hole 250a and straddle the first concave portion 113 of the main control device 101 and the front wall portion 250 of the movable base portion 203. Affix. A seal seal is a seal that has the property that it cannot be reapplied when it is peeled off after it has been applied once, and its trace remains at the application position. For this reason, after sticking the seal seal, the main controller 101 cannot be removed from the movable base 203 unless the fixing screw 251 is removed after leaving a peeled trace. Therefore, it is easy to check whether or not the main controller 101 has been illegally removed from the movable base 203 by checking whether or not the traces of the seal seal have been left on the first recess 113 and the front wall 250. Can be judged.

  Further, as another sealing process, a connection process between the main controller 101 and the movable base unit 203 is performed. Specifically, the connecting pin 137 is inserted into the first insertion hole 138 provided in the main controller 101 and the second insertion hole 254 provided in the movable base 203 from the main controller 101 side. . The main control device 101 can slide up and down with respect to the movable base portion 203, whereas the first insertion hole portion 138 and the second insertion hole portion 254 are through-holes with respect to the main control device 101 and the movable base portion 203. Therefore, when the connecting pin 137 is inserted, the main control device 101 moves in the vertical direction with respect to the movable base 203, that is, moves to the mounting side and the detaching side. Be regulated. As will be described in detail later, when the connecting pin 137 is inserted, the base end side portion of the connecting pin 137 is accommodated in the first insertion hole 138 and is locked with the first insertion hole 138. The distal end side portion is accommodated in the second insertion hole 254 and locked with the locking plate 255 provided in the second insertion hole 254. That is, the insertion of the connecting pin 137 restricts the movement of the main control device 101 in the front-rear direction with respect to the movable base portion 203. As a result, when the connecting pin 137 is inserted, the movement of the main control device 101 to the removal side with respect to the movable base portion 203 is restricted not only by the fixing screw 251 but also by the connecting pin 137. Unless the locked state of the first insertion hole 138 and the locked state of the connecting pin 137 and the locking plate 255 are released, the main controller 101 cannot be removed from the movable base 203.

  On the other hand, when the main controller 101 is removed from the movable base 203, it is necessary to release the connection by the connection pin 137. When releasing the connection, the bridging portion 139 that connects the first insertion hole 138 and the main controller 101 is cut from the main controller 101 using a tool such as a nipper, and the locking plate 255 is inserted into the second portion. The connecting pin 137, the first insertion hole 138, and the locking plate 255 in the locked state are detached from the hole 254 and separated from the main controller 101 and the movable base 203. The connecting pin 137 in the locked state, the first insertion hole 138, and the locking plate 255 are separated from the main controller 101 and the movable base 203, and the sealing seal is removed to remove the fixing screw 251 from the main controller 101. Accordingly, movement of the main control device 101 to the removal side with respect to the movable base portion 203 is allowed, and the main control device 101 can be detached from the movable base portion 203. Incidentally, when the main control device 101 and the movable base portion 203 are sealed again after the main control device 101 is detached from the movable base portion 203, the first insertion hole portion 138 that is not separated from the main control device 101 is inserted into the first insertion hole portion 138. A connection process for inserting the connection pin 137 is performed.

  As described above, when the main control device 101 is removed from the movable base portion 203 after the main control device 101 and the movable base portion 203 are sealed, the bridging portion 139 is cut and the coupling pin 137 in the locked state is connected. It is necessary to separate the first insertion hole 138 and the locking plate 255 from the main controller 101 and the movable base 203. When the locked connection pin 137, the first insertion hole 138, and the locking plate 255 are separated from the main controller 101 and the movable base 203, the cut trace of the bridging portion 139 is the main control. Clearly left on the device 101. In other words, the main control device 101 that has been subjected to the sealing process cannot be removed from the movable base portion 203 unless the trace of the sealing of the main control device 101 is left. Therefore, by confirming the cut trace of the bridging portion 139 and the cut trace of the first insertion hole 138, it is possible to easily grasp the removal history of the main controller 101 being removed.

  Further, when the main controller 101 and the movable base unit 203 are connected, if the date and time of the connection process and the name of the operator are written on the sealing history sheet attached to the sticking frame 116, the sealing history By comparing the content described on the sheet with the removal history remaining in the main control device 101, it can be easily determined whether the main control device 101 has been illegally removed.

  Here, a specific flow in which the sealing process of the substrate box 110 and the connection process of the main control device 101 are performed will be described.

  First, when manufacturing the slot machine 10, when the main board 105 is accommodated in the board box 110 and the main control device 101 is assembled, for example, the first sealing member 121 and the second sealing member at the position “A” shown in FIG. The sealing pin 122 is inserted into the member 135 and sealed so that the substrate box 110 is not opened. When the main control device 101 is mounted on the pedestal device 201, the connecting pin 137 is inserted into the first insertion hole 138 and the locking plate 255 at the position “B” shown in FIG. It connects so that it may not remove from the part 203. FIG.

  When the main board 105 is taken out from the board box 110 due to a malfunction or inspection of the main control device 101, if the operation is the first time, the connecting pin 137 at the position “B”, the first insertion The hole 138 and the locking plate 255 are separated from the main control device 101 and the movable base portion 203, and the main control device 101 is removed from the movable base portion 203. Thereafter, the first sealing member 121, the second sealing member 135, and the sealing pin 122 at the position “A” are separated from the main controller 101, and the main substrate 105 is removed from the substrate box 110.

  When the repair or inspection of the main board 105 is completed, the main board 105 is accommodated in the board box 110 and mounted on the movable base portion 203 without sealing the board box 110. Then, a connecting pin 137 is inserted into the first insertion hole 138 and the locking plate 255 at the position “C” shown in FIG. 6, and the main controller 101 is connected so as not to be detached from the movable base 203.

  Here, the sealing process of the board box 110 is not performed after the repair or inspection of the main board 105 is completed, but since the connection process of the main control device 101 and the movable base 203 is performed, the main control device 101 is It cannot be removed from the movable base 203, and as a result, the substrate box 110 cannot be opened. That is, by performing the connection process between the main control device 101 and the movable base portion 203, not only can the main control device 101 and the movable base portion 203 be sealed, but also the substrate box 110 can be sealed.

  When the main board 105 is taken out of the board box 110 due to a malfunction or inspection of the main control device 101 for the second time, the connecting pin 137 at the position “C”, the first insertion hole 138, The locking plate 255 is separated from the main control device 101 and the movable base portion 203, and the main control device 101 is removed from the movable base portion 203. Thereafter, the main board 105 is removed from the board box 110. When the repair or inspection of the main substrate 105 is completed, the main substrate 105 is accommodated in the substrate box 110 and mounted on the movable base portion 203 without performing the sealing process of the substrate box 110. Then, the connecting pin 137 is inserted into the first insertion hole 138 and the locking plate 255 at the position “D” shown in FIG. 6, and the main controller 101 is connected so as not to be detached from the movable base 203.

  When the above operations are repeated and the first insertion holes 138 at the positions “B”, “C”, “D”, and “E” shown in FIG. 6 are separated from the main controller 101, that is, all the first insertion holes. When the part 138 is separated from the main controller 101, the sealing pin 122 is inserted into the first sealing member 121 and the second sealing member 135 at the position “F” shown in FIG. Ship. The manufacturer or the like of the slot machine 10 separates the first sealing member 121, the second sealing member 135, and the sealing pin 122 at the position “F” from the main control device 101, and takes out the main substrate 105 from the substrate box 110 to create a new one. Housed in the substrate box 110. Thereafter, the sealing pin 122 is inserted into the first sealing member 121 and the second sealing member 135 at the position “A” shown in FIG. 6 and returned to the shipping source. The number of the first insertion holes 138, the position where the first sealing member 121 (second sealing member 135) is provided, the display method of each position, and the like are not limited to the example described above, and are arbitrary.

  Next, a procedure for removing the main control device 101 from the pedestal device 201 in a state where the main control device unit 100 is attached to the back plate 11c of the housing 11 will be described based on FIG. Since the connection between the main control device 101 and the movable base unit 203 has been described above, the description thereof is omitted here.

  The main controller unit 100 has a fixed base portion 202 of the pedestal device 201 fixed to the back plate 11c of the housing 11, and a movable base portion 203 supported so as to be rotatable about a rotation center axis extending in the left-right direction. Has been. And main controller 101 with which movable base part 203 was equipped is attached to case 11 so that it can be arranged selectively in a standing posture state and a tilting posture state.

  In the state shown in FIG. 15A, the movable base portion 203 and the main control device 101 are positioned and held in a standing posture state by left and right locking pieces 223 provided on the fixed base portion 202.

  When removing the main controller 101 from such a state, the locking pieces 223 are elastically deformed to the side away from each other to release the locking of the locking pieces 223 and the movable base portion 203, and the upper end of the movable base portion 203. The part is rotated so as to be pulled out to the front side of the housing 11. As a result, the movable base portion 203 tilts toward the front surface side of the housing 11 with the support pin 248 as the center of rotation. Then, the protruding piece 237 of the movable base portion 203 comes into contact with a notch portion 222a formed in the front wall portion 222 of the fixed base portion 202, and as shown in FIG. It is positioned and held in the rotated position (tilted posture state).

  After the movable base portion 203 is positioned and held in the tilted posture state, the locking portion 252 of the movable base portion 203 is elastically deformed to the side away from the main control device 101, and the protrusion 146 and the locking portion 252 of the main control device 101 are elastically deformed. The locked state with the through hole 252a is released. Then, as shown in FIG. 15 (c), the main control device 101 is slid and moved along the back plate portion 231 of the movable base portion 203 toward the side away from the shaft portion 234, whereby the main control device 101 is controlled from the movable base portion 203. Device 101 can be removed. In addition, when attaching the main control apparatus 101 to the base apparatus 201, it can attach by performing the procedure reverse to the said procedure.

  By attaching the main controller unit 100 having such a configuration to the back plate 11c of the housing 11, the following excellent effects can be obtained.

  By adopting a configuration in which the movable base portion 203 is supported so as to be pivotable back and forth with respect to the fixed base portion 202, the front surface of the main substrate 105 in the substrate box 110 is viewed from the front side of the housing 11 in the standing posture state. In the tilted posture state, the rear surface of the main board 105 can be viewed from the front side of the housing 11. Certainly, the movable base 203 may be supported so as to be pivotable to the left and right with respect to the fixed base 202. However, when the IC chip 106 corresponding to the slot type mounting method is mounted on the main board 105 so as to extend in the left-right direction, the IC chip can be seen from the front side of the housing 11 even if the movable base 203 is rotated. Only the side surface having a small area 106 can be visually recognized, and it may be possible to complicate the work of checking whether the IC chip 106 has been replaced with an illegal IC chip. On the other hand, when the movable base portion 203 is supported so as to be pivotable back and forth, the IC chip 106 has a large area from the front side of the housing 11 when the movable base portion 203 is pivoted. The upper and lower surfaces can be visually recognized, and the confirmation work can be easily performed. In addition, by adopting a configuration that is supported so as to be pivotable back and forth, when rotating from the standing posture state to the tilting posture state, a force that rotates downward due to gravity can be applied to the movable base portion 203. This makes it easy to turn to the tilted posture state.

  When the notch 222a is formed on the front plate 222 of the fixed base 202 and the protruding piece 237 is formed on the movable base 203, and the movable base 203 is rotated forward, the notch 222a The projecting piece 237 is in contact with the movable base 203 so that the movable base 203 is positioned and held in a tilted posture. With this configuration, when the main control device 101 is detached from the pedestal device 201 or attached to the pedestal device 201, the main control device 101 is slid with the other hand while the movable base 203 is positioned and held with one hand. Instead of moving, the main controller 101 can be slid using both hands. Therefore, it is possible to facilitate the attachment work and the removal work of the main control apparatus 101, and it is possible to improve work efficiency.

  A metal support pin 248 is used as a support member that rotatably supports the movable base portion 203 on the fixed base portion 202. Accordingly, both sides in the axial direction are supported by the side wall portion 233 and the overhang plate portion 246 of the movable base portion 203 made of synthetic resin. With this configuration, the support pin 248 can be firmly supported by the movable base portion 203, and the support rigidity of the movable base portion 203 and the fixed base portion 202 can be increased.

  Protruding pieces 237 and notches 222a for positioning and holding the movable base portion 203 in the tilted posture state are arranged at both left and right ends where the support pins 248 are inserted. When the protruding piece 237 and the notch 222a are arranged in the central portion where the support pin 248 is not inserted, there is a possibility that the shaft portion 234 is warped in the tilted posture state. However, by disposing the protruding pieces 237 and the notches 222a at the left and right ends where the support pins 248 are inserted, the rigidity of the movable base 203 can be ensured, and the occurrence of the above-described problems can be avoided.

  The main controller 101 and the movable base portion 203 are provided with a second recess 114 having a fixing portion (screw hole, insertion hole 250a) and a front wall portion 250 for fixing the main control device 101 to the movable base portion 203 on the front surface. Formed in the lower right side. With this configuration, when fixing the main controller 101 to the movable base 203, the fixing screw 251 can be screwed in from the front of the housing 11, and the fixing operation can be facilitated. it can. Further, since the front door 12 is pivotally supported on the left side portion of the housing 11, a wide working space around the front wall portion 250 can be secured by opening the front door 12, and the fixing screw 251 Fixing work and removal work can be easily performed. Therefore, it is possible to easily perform the operation of assembling the main control device 101 to the movable base portion 203 of the base device 201 and the operation of removing it.

  The pedestal device 201 is fixed to the back plate 11c of the housing 11 with fixing screws from both front and rear directions. In such a configuration, even if the fixing screw screwed in from the front of the back plate 11c is removed, the pedestal device 201 is removed from the housing 11 as long as the fixing screw screwed in from the rear of the back plate 11c is not removed. Since it cannot be removed, it is difficult to remove the pedestal device 201 from the housing 11. When the main control device 101 is mounted on the movable base portion 203 and positioned and held in the standing posture, the opening hole portion 238 and the window portion 241 of the movable base portion 203 and the opening of the fixed base portion 203 are provided. Since both the hole 216 and the insertion hole 215d are closed by the main controller 101, the fixing screw screwed into the position cannot be removed, and the pedestal device 201 cannot be removed from the housing 11. Further, since each of the holes 215d, 216, 238, 241 is provided at the lower part of the corresponding base part 202, 203, more specifically at the end of the movable base part 203 on the rotation center side, Even if the movable base 203 is positioned and held in the tilted posture, the main controller 101 and the movable base 203 are obstructed, and a tool such as a screwdriver can be inserted into the holes 215d and 216 on the fixed base 202 side. The pedestal device 201 cannot be removed from the housing 11.

  As a result of the above, when the main controller 101 is mounted on the movable base 203, the fixing screws inserted through the holes 215d, 216, 238, 241 are inserted in both the standing posture and the tilting posture. It cannot be removed and the main controller unit 100 can be prevented from being stolen.

  By the way, as a fraud to the main control device 101, in addition to a fraud in which the main control device unit 100 is stolen as it is, the main control device 101 separated from the fixed base portion 202 and attached to the movable base portion 203. It is also conceivable to cheat.

  Therefore, the support pin 248 that connects the movable base portion 203 and the fixed base portion 202 is made of metal, and the inserted support pin 248 cannot be removed from the movable base portion 203. By adopting such a configuration, it is possible to prevent the act of destroying the support part that rotatably supports the movable base part 203 with a tool or the like and the action of removing the support pin 248. Therefore, it is possible to prevent fraud in which the main controller 101 mounted on the movable base 203 is stolen by separating the movable base 203 from the fixed base 202.

  In addition, the fixed base portion 202 and the movable base portion 203 are formed with lock attachment holes 221c and 249 that are coaxial in the standing posture state. For this reason, if the movable base portion 203 is positioned and held in a standing posture, for example, a game manager or the like inserts a U-shaped bar or the like of a padlock into the lock mounting holes 221c and 249 and locks the fixed base portion 202. And the movable base part 203 can be made into the locked state which cannot be rotated. In a state where the main control unit 100 is attached to the housing 11, if the main control device 101 is to be removed from the movable base portion 203 in a standing posture, the top plate 11 a of the housing 11 is removed due to an obstacle. Since the movable base portion 203 is locked to the fixed base portion 202, the illegal operation of separating the movable base portion 203 from the fixed base portion 202 and stealing the main control device 101 attached to the movable base portion 203 is prevented. It becomes possible to prevent.

  Further, in addition to the above-described fraud with respect to the main control device 101, there may be a fraud that directly removes the main control device 101 from the movable base 203. Therefore, the main controller 101 and the movable base 203 are sealed. With this configuration, it is possible to prevent the main controller 101 from being removed directly from the movable base 203.

  In the present embodiment, the movable base 203 is connected to the main controller 101, that is, the connecting pin 137 as a connecting member, the first insertion hole 138 as the first connecting member, and the first as the opening hole. It has the characteristics in the structure of the 2 insertion hole part 254 and the latching plate 255 as a 2nd coupling member. Therefore, these configurations will be described in detail below. For ease of explanation, the assembly of the members 137, 138, 254, and 255 is referred to as a connecting means.

  16 is a perspective view of the connecting pin 137, FIG. 17 is a rear perspective view of the locking plate 255, FIG. 18 is a rear view of the locking plate 255, FIG. 19 is a rear perspective view of the box case 131, and FIG. FIG. 21 is a cross-sectional view of the connecting means, FIGS. 23 and 24 are exploded views of the connecting means, and FIG. 25 is related to the connecting pin 137. FIG. 26 is a diagram illustrating a state in which the connecting pin 137 and the first insertion hole 138 are connected, partly in cross section.

  The connection means is for preventing the main control device 101 from being illegally detached from the movable base portion 203 of the pedestal device 201. The connection means is provided on the connection pin 137 and the movable base portion 203 and the tip of the connection pin 137. A locking plate 255 in which the side portion is inserted and locked, and a first insertion in which the base end side portion of the connecting pin 137 is inserted and locked facing the locking plate 255 in the board box 110. A hole 138 is provided.

  As shown in FIG. 16, the connecting pin 137 is made of a synthetic resin material such as polycarbonate having a predetermined rigidity, and has a round bar-shaped shaft portion 302 (main body portion). The shaft portion 302 has a cylindrical shape having a predetermined thickness, and a disc-shaped jaw portion 303 (first regulating portion) having a diameter increased through a step is provided at the proximal end of the shaft portion 302. It has been.

  The shaft portion 302 is provided with a distal end side locking claw 304 (second regulating portion) and a proximal side locking claw 305 (third regulating portion) on the distal end side portion and the proximal end side portion of the shaft portion 302, respectively. Yes. The distal end side locking claws 304 and the proximal end side locking claws 305 are provided in pairs, and the distal end side locking claws 304 are provided at positions separated from each other with the central axis of the shaft portion 302 interposed therebetween. The base end side locking claws 305 are also provided at positions separated from each other with the central axis of the shaft portion 302 interposed therebetween. The distal-side locking claws 304 and the proximal-side locking claws 305 are positioned at a phase angle of 90 degrees between the direction in which the distal-side locking claws 304 are separated from each other and the direction in which the proximal-side locking claws 305 are separated from each other. Have a relationship.

  The front end side claw 304 includes an arm portion 304 a extending from the front end of the shaft portion 302 along the axial direction of the shaft portion 302, and a claw portion protruding from the arm portion 304 a toward the radially outer side than the shaft portion 302. It has 304b (protrusion part).

  The arm portion 304a is formed so as to extend along the axial direction with substantially the same thickness as the thickness of the shaft portion 302. The arm portion 304a is elastically deformed by applying a predetermined urging force so that the claw portion 304b is pivoted. The claw portion 304b can be returned to its original position by being moved toward the inside in the radial direction of the portion 302 and restored by disappearance of the urging force.

  The claw portion 304b is formed such that the outer surface of the claw portion 304b is inclined so as to gradually move toward the radially outer side of the shaft portion 302 as it moves from the distal end side to the proximal end side of the shaft portion 302. When the distal end portion of the connecting pin 137 is inserted into the opening hole 313 (the communication hole portion, see FIG. 17) of the locking plate 255, the arm portion 304a can be elastically deformed by coming into contact with the opening hole 313. It has become. Further, the base end of the claw portion 304 b is formed in a planar shape along the radial direction of the shaft portion 302.

  The proximal end side locking claw 305 is an arm portion that extends from the proximal end side of the shaft portion 302 toward the distal end side along the axial direction of the shaft portion 302 in a window portion 302 a formed in the shaft portion 302. 305a and a claw portion 305b (protruding portion) that protrudes from the arm portion 305a toward the radially outer side than the shaft portion 302.

The body 332 is supported at a substantially central position in the direction. The body 332 can be separated from the box case 131 by cutting a portion located above and below the body 332 with a tool such as a nipper.

  The bridging portion 139 extends so that the central axis of the trunk portion 332 extends in a direction perpendicular to the covering portion 132 of the box case 131, and the rear end surface of the trunk portion 332 is flush with the rear surface of the covering portion 132. The trunk portion 332 is supported.

  The bridging portion 139 has a constant thickness and a constant width at both the left and right positions of the trunk portion 332 and extends vertically, and the rear end edge of the bridging portion 139 is located on the front side of the rear end surface of the trunk portion 332 (box The rear end edge of the bridging portion 139 has a predetermined gap with the back plate portion 231 of the movable base portion 203 with the substrate box 110 held by the movable base portion 203 at the position of the cover 111 side. It is provided so that it may be located in the position spaced apart.

  In this way, by providing a predetermined gap between the rear edge of the bridging portion 139 and the back plate portion 231 of the movable base portion 203, for example, a tool is inserted from the box cover 111 side to cut the bridging portion 139. Sometimes, the tool can be surely brought into contact with the bridging portion 139, and the bridging portion 139 can be easily cut.

  In the present embodiment, the bridging portion 139 has a front and rear width that is approximately half the axial length of the trunk portion 332, and the front end edge of the bridging portion 139 is flush with the front end surface of the trunk portion 332. A rear end edge portion of the bridging portion 139 is formed so as to be positioned at a substantially central position in the axial direction of the trunk portion 332.

  As shown in FIGS. 22 and 24, the body portion 332 has a cylindrical shape having a certain thickness, and the distance from the flange portion 303 of the connecting pin 137 to the distal end of the proximal end side locking claw 305. It has an axial length that is substantially the same.

  The center hole 333 of the trunk portion 332 is larger than the outer diameter of the flange portion 303 of the connecting pin 137 and has an inner diameter that allows the flange portion 303 to be inserted with a predetermined gap. In the center hole 333, a locking portion 336 is provided to lock the claw portion 305b of the base end side locking claw 305 so that the connecting pin 137 cannot be pulled out from the body portion 332.

  As shown in FIG. 20, the locking portion 336 protrudes from the center hole 333 so as to be separated from each other in the left-right direction. Each locking portion 336 has an inner peripheral surface 335 facing the outer peripheral surface of the shaft portion 302 of the connecting pin 137 in a state where the connecting pin 137 is inserted into the center hole 333 of the trunk portion 332. The inner peripheral surface 335 is formed so as to be curved in an arc shape with a radius slightly larger than the outer diameter of the shaft portion 302 around the same central axis as the center hole 333. Further, in the central axis direction of the center hole 333, the locking portion 336 has a distance from the rear end surface of the locking portion 336 to the rear end surface of the trunk portion 332, so that the base end of the claw portion 305 b of the base end side locking claw 305 is It is formed to be almost the same as the distance from the tip to the tip. In other words, the locking portion 336 inserts the base end side portion of the connecting pin 137 into the center hole 333 of the trunk portion 332 so that the claw portion 305b of the base end side locking claw 305 is positioned more than the rear end surface of the locking portion 336. It is configured so that the claw portion 305b of the proximal end side locking claw 305 can be accommodated in the body portion 332 in a state of protruding rearward.

  Of the end faces of the locking portions 336 located on both axial sides of the center hole 333, the rear end face located on the axial rear side of the center hole 333 is formed in a planar shape along the radial direction of the center hole 333. In a state where the base end side portion of the connecting pin 137 is inserted into the center hole 333 of the body portion 332, the claw portion 305 b of the base end side locking claw 305 protrudes rearward from the rear end surface of the locking portion 336. The base end side locking claw 305 can be opposed to the base end of the claw portion 305b.

  Therefore, in a state where the base end side portion of the connecting pin 137 is inserted into the center hole 333 of the trunk portion 332 and the claw portion 305b of the base end side locking claw 305 protrudes rearward from the rear end surface of the locking portion 336. When the connection pin 137 is moved in the direction of pulling out from the distal end side to the proximal end side of the connection pin 137, the proximal end of the claw portion 305b of the proximal end side engagement claw 305 is moved to the rear of the engagement portion 336. It can be locked by preventing the movement toward the drawing side by contacting the end surface.

  Of the end faces of the locking portions 336 located on both sides in the axial direction of the center hole 333, the front end face 337 located on the front side in the axial direction of the center hole 333 gradually increases as it moves from the front side in the axial direction toward the rear side. It is formed in a tapered shape with a reduced diameter. Therefore, when the base end side portion of the connecting pin 137 is inserted into the center hole 333 of the body portion 332, the arm portions 305a are brought closer to each other by coming into contact with the claw portion 305b of the base end side locking claw 305. It can urge toward and can easily pass between a pair of opposed inner peripheral surfaces 335.

  In the center hole 333 of the body portion 332, the base pin side locking claw 305 and the locking portion 336 are locked by rotating the connecting pin 137 relative to the first insertion hole portion 138. A passage portion 339 is provided as a base end side unlocking means for releasing the.

  The passage portion 339 can move the connecting pin 137 without being caught by the claw portions 304b and 305b when trying to move the connecting pin 137 in a direction to be pulled out from the distal end side to the proximal end side of the connecting pin 137. It can be done. The passage portion 339 is vertically spaced apart from each other in the center hole 333 to form a pair, and the width of the claw portion 304b of the distal end side locking claw 304 in the circumferential direction of the shaft portion 302 and the proximal side locking claw 305 in the circumferential direction. The claw portion 305b has a width wider than the width of the claw portion 305b.

  Accordingly, the base end side portion of the connecting pin 137 is inserted into the center hole 333 of the body portion 332, and the claw portion 305 b of the base end side locking claw 305 protrudes rearward from the rear end surface of the locking portion 336. The coupling pin 137 is rotated relative to the body portion 332 of the first insertion hole portion 138 so that the phases of the claw portion 305b and the passage portion 339 coincide with a preset rotational phase position. Opposition of the claw portion 305b to the rear end surface of the stop portion 336 can be released.

  Then, the claw portion 305b can be passed through the passage portion 339 and pulled out from the trunk portion 332 by moving the connecting pin 137 as it is toward the pulling side opposite to the insertion direction.

  In addition, the connecting pin 137 is inserted into the body portion 332, and the connecting pin 137 is connected to the body portion in a state where the claw portion 304b of the front end side engaging claw 304 protrudes rearward from the rear end surface of the engaging portion 336. The claw portion 304b is opposed to the rear end surface of the locking portion 336 by rotating relative to the 332 to make the phase of the claw portion 304b and the passage portion 339 coincide with a preset rotation phase position. can do.

  Then, the claw portion 304b can be passed through the passage portion 339 and pulled out from the trunk portion 332 by moving the connecting pin 137 as it is in the pulling direction opposite to the inserting direction. Therefore, the connecting pin 137 can be removed from the locking plate 255 and the first insertion hole 138 without destroying the connecting pin 137, and the connecting pin 137 can be used again.

  Next, the operation of the connecting means will be described.

  In order to connect the board box 110 to the movable base portion 203 by the connecting means, first, the fitting convex portion of the first coupling piece 255a is fitted with the fitting concave portion of the second coupling piece 255b, and the first coupling piece 255a is also fitted. The fitting concave portion is fitted to the fitting convex portion of the second coupling piece 255b, and the locking plate 255 is assembled. Then, the locking plate holding claw 315 is inserted into the claw hole 254 c of the second insertion hole 254, and the rear surface of the flat plate portion 312 of the locking plate 255 and the rear surface of the rectangular recess 254 a of the second insertion hole 254 are in contact with each other. By pushing backward until it comes into contact, the base end of the claw portion 315b of the holding claw 315 protrudes rearward from the rear end surface of the claw hole portion 254c. In this state, the movement of the locking plate 255 further rearward (moving to the attachment side) is regulated by the locking of the flat plate portion 312 and the rectangular recess 254a, and the locking plate 255 moves forward (removal side). Movement) is restricted by the engagement between the base end of the claw portion 315b of the holding claw 315 and the rear surface of the claw hole portion 254c. As a result, the locking plate 255 is held in the second insertion hole 254 of the movable base 203.

  After mounting the locking plate 255 in the second insertion hole 254, the board box 110 is installed on the movable base 203. Thereafter, the connecting pin 137 is inserted into the body 332 of the first insertion hole 138 from the front of the substrate box 110. The connecting pin 137 is inserted into the body part 332 from the front end side in a posture that is coaxial with the body part 332 and in which each front end side locking claw 304 is positioned vertically.

  The front-end side locking claw 304 of the connecting pin 137 is inserted into the center hole 333 of the trunk portion 332, the claw portion 304 b passes through the passage portion 339 of the trunk portion 332, and the tip end of the claw portion 304 b projects from the trunk portion 332. Then, it is inserted to the position where it enters the opening hole 313 of the locking plate 255. As a result, the claw portions 304b of the front end side locking claws 304 abut on the opening holes 313 of the locking plate 255, and the claw portions 305b of the proximal end side locking claws 305 abut on the front end surface 337 of the locking portion 336. It is assumed that

  Then, by further pushing the connecting pin 137, the claw portion 304b of the distal end side claw 304 is urged in a direction to abut against the opening hole 313 and elastically deform the arm portion 304a. , Moves into the opening hole 313, passes through the opening hole 313, protrudes rearward from the rear end surface of the locking portion 316, as shown in FIG. Intervening in between. When the claw portion 304b passes through the opening hole 313 and protrudes from the locking portion 316, the urging force by the opening hole 313 is released, the arm portion 304a is restored, the bending is restored, and the base end of the claw portion 304b is restored. Is disposed at a position facing the rear end surface of the locking portion 316.

  On the other hand, the claw portion 305b of the proximal end side locking claw 305 is urged in a direction to contact the front end surface 337 of the locking portion 336 and elastically deform the arm portion 305a, and toward the radially inner side of the shaft portion 302. It moves and passes between the pair of locking portions 336 and protrudes rearward from the rear end surface of the locking portion 336 as shown in FIG. When the claw portion 305b passes between the pair of locking portions 336 and protrudes rearward from the rear end surface of the locking portion 336, the urging force by the locking portion 336 is released, and the arm portion 305b is restored and bent. Returning to the original position, the base end of the claw portion 305 b is disposed at a position facing the rear end surface of the locking portion 336.

  In this position, the connecting pin 137 has the front end surface of the flange portion 303 substantially flush with the front end surface of the body portion 332. If the connecting pin 137 is further moved from this position to the insertion side, the distal end of the distal end side locking claw 304 is locked with the round hole portion 254b, and the movement to the insertion side is restricted. The movement of the end of the end side locking claw 305 to the insertion side by locking with the flat plate portion 312 of the locking plate 255 is restricted, and the collar portion 303 is locked to the front end surface 337 of the locking portion 336 and inserted. Movement to the side to be controlled. Therefore, the movement of the connecting pin 137 to the further insertion side is restricted. On the other hand, when trying to move the connecting pin 137 to the pulling side opposite to the insertion side, the claw portion 304b of the front end side locking claw 304 is locked with the rear end surface of the locking portion 316 and pulled out. Movement is restricted, and movement of the claw portion 305b of the proximal end side locking claw 305 to the rear end surface of the locking portion 336 is restricted. Therefore, the movement of the connecting pin 137 to the drawing side is prevented. As a result, when the connecting pin 137 is inserted at the above position, the connecting pin 137 cannot be removed from the locking plate 255 and the first insertion hole 138. Accordingly, the substrate box 110 is coupled to the movable base portion 203, and the sliding movement of the substrate box 110 with respect to the movable base portion 203 is prohibited, so that the substrate box 110 cannot be pulled out from the movable base portion 203 and removed. .

  In order to release the connection by the connecting means, first, the bridging portion 139 of the body portion 332 on which the connecting pin 137 is locked is cut with a tool such as a nipper.

  The bridging portion 139 is cut at a location located above and below the trunk portion 332. Since the bridging portion 139 is provided at a position spaced apart from the back plate portion 231 of the movable base portion 203 with a predetermined gap, the bridging portion 139 is cut by inserting a tool from the box cover 111 side. Sometimes, the tool can be surely brought into contact with the bridging portion 139, and the bridging portion 139 can be easily cut. By cutting the bridging portion 139, the body portion 332 of the first insertion hole 138 is separated from the box case 131.

  Next, the locking plate 255 is removed from the movable base portion 203. When removing the locking plate 255 from the movable base portion 203, first, the movable base portion 203 is tilted from the standing posture state to be positioned and held in the tilted posture state, and the rear surface of the second insertion hole 254 of the movable base portion 203 is visually confirmed. Make it possible. Then, the left and right claw portions 315b that protrude to the rear surface side of the second insertion hole portion 254 and are hooked on the claw hole portion 254c are elastically deformed to approach each other, and the hooks of the claw portion 315b and the claw hole portion 254c are removed. . Thereafter, the locking plate 255 is removed from the second insertion hole 254 by inserting the claw portion 315b into the claw hole portion 254c and moving the locking plate 255 forward (to the board box 110 side). By performing such an operation, the body 332 and the locking plate 255 can be taken out in front of the substrate box 110 in a state where they are connected to each other by the connecting pins 137. Further, by removing the locking plate 255 from the second insertion hole 254, the locking plate 255 is interposed between the locking portion 316, the rotation restricting portion 318, and the rotation restricting portion 318 of the locking plate 255. The nail | claw part 304b of the front end side latching claw 304 currently exposed is exposed (refer FIG. 25). By removing the body 332 and the locking plate 255 connected by the connecting pin 137 to the front of the substrate box 110, the connection between the movable base 203 and the substrate box 110 by the connecting means is released, and the substrate box 110 is moved to the movable base. It can be pulled out from the portion 203 and removed. In addition, the nail | claw part 315b of the latching plate 255 and the nail | claw hole part of the 2nd insertion hole part 254 do not cut | disconnect the bridge | bridging part 139, ie, without cut | disconnecting the trunk | drum 332 of the 1st insertion hole part 138 from the box case 131. When it is attempted to move the locking plate 255 forward by removing the catch of 254c, the front surface of the locking plate 255 comes into contact with the rear surface of the body portion 332 and the forward movement is restricted. Therefore, the movement of the locking plate 255 to the removal side is prevented.

  The connecting pin 137 is removed from the locking plate 255 and the body portion 332 for reuse, that is, for example, to connect the locking plate 255 and the first insertion hole 138 located next to each other. For removal from the locking plate 255 and the body 332, first the locking plate 255 is removed, and then the body 332 is removed.

  When the locking plate 255 is removed from the connecting pin 137, the fitting portion is fitted by moving the first coupling piece 255a and the second coupling piece 255b constituting the locking plate 255 to the side away from each other. To release. As a result, the locking plate 255 is divided into two members with the center line of the opening hole 313 as the center, that is, with the center line in the radial direction of the shaft portion 302 of the connecting pin 137 as the center. As a result, the connecting pin 137 is allowed to move from the first connecting piece 255a (second connecting piece 255b) to the one side in the radial direction of the shaft portion 302, and the locking plate 255 can be removed from the connecting pin 137. That is, by releasing the fitting of the first coupling piece 255a and the second coupling piece 255b, a predetermined direction orthogonal to the axial direction of the shaft portion 302 (downward with respect to the first coupling piece 255a, the second coupling piece The connection pin 137 is allowed to move upward (toward 255b), and the locking plate 255 can be removed from the connection pin 137. When such an operation is performed, the locking plate 255 is only divided into two members after the fitting of the coupling pieces 255a and 255b is released and is not broken. Similarly, it can be reused.

  When the locking plate 255 is removed from the connecting pin 137, the distal end portion of the connecting pin 137 is exposed in a state of protruding from the body portion 332. Further, the claw portion 305 b of the base end side locking claw 305 is also exposed in a state of being accommodated in the trunk portion 332 from the rear end surface side of the trunk portion 332.

  When removing the connecting pin 137 from the body portion 332, the connecting pin 137 is rotated about 90 degrees around the central axis of the shaft portion 302, and the claw portion 305 b of the proximal end side locking claw 305 is moved to the locking portion 336. It is rotated from a position facing the rear end face (see FIG. 26) to a position coinciding with the passage portion 339. As a result, the hook between the claw portion 305b of the connecting pin 137 and the locking portion 336 of the body portion 332 is released, and in this state, the connecting pin 137 is moved to the side to be pulled out. The claw 305 passes through the passage portion 339.

  When the proximal end side locking claw 305 passes through the passage portion 339, the claw portion 304b of the distal end side locking claw 304 abuts on the rear end surface of the locking portion 336, and the movement of the connecting pin 137 to the side to be pulled out is restricted. The Here, the connecting pin 137 is rotated about 90 degrees around the central axis of the shaft portion 302, and the passage portion 339 and the passage portion 339 are moved from the position where the claw portion 304b of the front end side locking claw 304 faces the rear end surface of the locking portion 336. Move to the matching position. As a result, the hook between the claw portion 304b of the connecting pin 137 and the locking portion 336 of the body portion 332 is released, and in this state, the connecting pin 137 is moved to the side to be pulled out. 304 passes through the passage portion 339. As a result, the connecting pin 137 can be removed from the trunk 332.

  In this manner, the connecting pin 137 can be easily removed from the locking plate 255 and the body portion 332 without destroying the connecting pin 137.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The connection pin 137 is engaged with the first insertion hole 138 at the base end portion of the connection pin 137 so as to restrict the movement of the connection pin 137 to the insertion side and the engagement plate 255. In addition to the front end side claw 304 that restricts the connection pin 137 from moving to the pulling side, the connection pin 137 is prevented from moving to the pulling side by locking with the first insertion hole 138. Proximal end side locking claws 305 are provided. With this configuration, in the state where the first insertion hole portion 138 and the locking plate 255 are connected by the connecting pin 137, the round hole portion 254b of the second insertion hole portion 254 is temporarily cut and the distal end side locking claw is cut. Even when the lock between the lock plate 304 and the lock plate 255 is released, it is possible to restrict the movement of the connecting pin 137 to the side to be pulled out by the lock between the base end side locking claw 305 and the first insertion hole portion 138. It is possible to prevent the pin 137 from being removed from the first insertion hole 138 and the locking plate 255. Therefore, it is possible to prevent the main control device 101 and the movable base portion 203 from being illegally separated and performing an illegal act on the main board 105.

  The first insertion hole 138 has a locking claw portion 336 that locks with the proximal-side locking claw 305, and is configured so that the claw portion 305 b of the proximal-side locking claw 305 can be accommodated in the body portion 332. . With this configuration, a gap is formed by inserting a tool or the like between the first insertion hole 138 and the locking plate 255, and the engagement between the proximal locking claw 305 and the locking claw 336 is established from the clearance. It is possible to make the fraud for releasing the stop difficult.

  A flat plate portion 312 is formed on the locking plate 255 at the base end portion of the opening hole 313. With this configuration, in a state where the first insertion hole portion 138 and the locking plate 255 are connected by the connecting pin 137, the jaw portion 303 is temporarily cut so as to have the same diameter as the shaft portion 302 and the second insertion is performed. Even if the round hole portion 254b of the hole portion 254 is cut, the connection pin 137 is moved to the insertion side by the locking of the base end side locking claw 305 and the flat plate portion 312 of the locking plate 255 (the above-mentioned illegally). Based on the movement to the drawing side). Therefore, it is possible to prevent the connecting pin 137 from being removed from the first insertion hole 138 and the locking plate 255.

  The connecting pin 137 has a distal end side locking claw 304 and a base at a position where the direction in which each distal end side locking claw 304 is separated from the direction in which each proximal end side locking claw 305 is spaced is a phase angle of 90 degrees. The end side latching claw 305 was formed. By adopting such a configuration, even if one of the front end side locking claws 304 and the proximal end side locking claws 305 is illegally elastically deformed radially inward of the shaft portion 302, the other engagement The pawl cannot be elastically deformed inward in the radial direction of the shaft portion 302, and it is difficult to illegally unlock the latch pawls. In addition, in the configuration in which the window portion 302a is formed in the shaft portion 302 and the proximal end side locking claw 305 is provided in the portion, there is a concern that the rigidity of the shaft portion 302 is lowered, but the phase angle of 90 degrees By forming the distal end side locking claws 304 and the proximal end side locking claws 305 at the positions, the above concerns can be solved.

  The movable base portion 203 has an opening on the side facing the first insertion hole portion 138, and can receive the locking plate 255 and is formed with a bottomed second insertion hole portion 254. The locking plate 255 is attached to the movable base 203 so as to close the second insertion hole 254 from the opening side of the second insertion hole 254. By forming a second insertion hole 254 that opens on the side facing the first insertion hole 138 but does not open on the other side in the movable base 203, the connection pin 137 and the first insertion hole 138 In a state where the locking plate 255 is connected, the distal end side locking claw 304 cannot be touched from the rear surface side of the movable base portion 203, and the locking of the connecting pin 137 and the locking plate 255 is incorrect. It can be difficult to be released. Therefore, fraudulent acts on the main board 105 can be prevented.

  Certainly, for example, the main control can be directly performed on the back plate 11c of the housing 11 without forming the second insertion hole 254 so that the front end side claw 304 cannot be touched from the rear surface side of the movable base 203. If the device 101 is attached and the back plate 11c and the main control device 101 are provided with a connecting means, it is possible to make the configuration incapable of touching the distal end side locking claws 304. However, in such a configuration, when an illegal substrate or the like is installed on the rear surface side of the main control device 101 or in a gap area between the main substrate 105 and the box case 111 in the substrate box 110, discovery of the illegal activity is delayed. Probability is high. In order to avoid such a concern, it is desirable to attach the main control device 101 to the movable base 203 so that the rear surface side of the main control device 101 is visible. Therefore, in the configuration in which the rear surface side of the main control device 101 is visible, the second insertion hole 254 is formed in the movable base portion 203 so that the front end side claw 304 cannot be touched from the rear surface side of the movable base portion 203. By adopting the configuration, it is possible to prevent both the above-described frauds.

  The locking plate 255 is attached to the movable base 203 so as to close the second insertion hole 254 from the opening side of the second insertion hole 254. In such a configuration, the claw portion 315b of the locking plate 255 and the second insertion hole portion 254 are not cut without cutting the bridging portion 139, that is, without separating the body portion 332 of the first insertion hole portion 138 from the box case 131. When the hook of the claw hole portion 254c is removed and the locking plate 255 is moved forward, the front surface of the locking plate 255 comes into contact with the rear surface of the body portion 332, and the forward movement is restricted. Therefore, even when the movable base portion 203 and the locking plate 255 are configured separately, it is possible to prevent the main control device 101 and the movable base portion 203 from being illegally separable. In addition, the latch plate 255 cannot be removed from the movable base portion 203 even when the hook portions 315b of the latch plate 255 and the hook holes 254c of the second insertion hole portion 254 are removed. If it is attempted to realize with only the stop plate 255 and the movable base portion 203, there is a concern that the mounting structure of the locking plate 255 and the movable base portion 203 may be complicated, but cooperation with the first insertion hole portion 138. By realizing below, the mounting structure can be simplified.

  When removing the locking plate 255 from the second insertion hole portion 254, the left and right claw portions 315b protruding to the rear surface side of the second insertion hole portion 254 and hooked on the claw hole portion 254c are elastic to the side approaching each other. The hooks 315b and the claw hole portions 254c are removed by deformation, and the claw portions 315b are inserted into the claw hole portions 254c to move the locking plate 255 forward. With this configuration, the locking plate 255 can be removed without destroying the second insertion hole 254. Therefore, for example, even when the first insertion hole portion 138 of the main controller 101 is completely cut out and the substrate box 110 is replaced with a new substrate box 110, the substrate box 110 is replaced without replacing the movable base portion 203. And the movable base portion 203 can be coupled, and the pedestal device 201 can be reused.

  Both the movable base 203 and the locking plate 255 are formed of a synthetic resin material. In such a configuration, the movable base provided with both the engaging portion that engages with the distal end side engaging claws 304 of the connecting pin 137 and the covering portion that covers the portion so that the distal end side engaging claws 304 cannot be touched. When trying to integrally mold the part or the locking plate, the mold structure becomes complicated, the molding defect rate increases, and there is a concern about cost increase. However, it is possible to eliminate the above-mentioned concern by separately forming the second insertion hole 254 having a function as a covering portion and the locking plate 255 having a function as a locking portion.

  The connection pin 137 can be easily removed from the locking plate 255 and the body portion 332 without destroying the connection pin 137. Therefore, the connection pin 137 can be reused, and only one connection pin 137 needs to be prepared for one slot machine 10, and there is no need to provide a spare connection pin 137. Therefore, after preventing the connection with the connection pin 137, the lock plate 255, and the first insertion hole 138 in the connected state, the unused connection pin 137 is replaced with the same lock plate again. It is possible to prevent a fraudulent act of impersonating if the connection between the movable base portion 203 and the substrate box 110 is not released yet by being inserted into the 255 and the first insertion hole portion 138. Further, for example, one of the movable base 203 or the substrate box 110 and the connecting pin 137 is made of a plastic material, and the other is made of a metal material. Can be separated and disposed of reliably. Therefore, each can be recycled as resource garbage, and effective utilization of resources can be achieved.

  When the first coupling piece 255a and the second coupling piece 255b are fitted, the locking plate 255 is assembled. In such a configuration, after the coupling pin 137, the first insertion hole 138, and the locking plate 255 in the coupled state are separated from the main controller 101 and the movable base 203, the fitting of the coupling pieces 255a and 255b is released. By doing so, the connecting pin 137 can be detached from the locking plate 255. Therefore, the connecting pin 137 can be easily detached from the locking plate 255. Further, since the connection pin 137 and the locking plate 255 can be separated without destroying the connection pin 137 and without destroying the coupling pieces 255a and 255b, these members can be reused. .

  Each of the coupling pieces 255a and 255b is divided into two vertically divided by the center line in the left and right direction of the locking plate 255, and the fitting portion of each of the coupling pieces 255a and 255b is orthogonal to the direction in which the holding claws 315 extend. It was formed to extend in the direction. For this reason, when the holding claw 315 is inserted into the claw hole 254c of the second insertion hole 254, the holding claw 315 comes into contact with the claw hole 254c, and the stress that elastically deforms the holding claw 315 on the locking plate 255 is applied. Even if added, it is possible to prevent the locking plate 255 from being split by releasing the fitting of the coupling pieces 255a and 255b. In particular, since the fitting portion is formed at the proximal end portion of the holding claw 315, the above concern can be preferably solved. In a configuration in which stress is applied to the holding claw 315 of the locking plate 255, the locking plate 255 is inserted into the second insertion hole 254 while pressing the upper and lower portions of the locking plate 255 where the holding claw 315 is not provided. Instead, when the locking plate 255 is inserted into the second insertion hole 254 while pressing the left and right portions of the locking plate 255 provided with the holding claws 315, that is, the fitting portions of the coupling pieces 255a and 255b. It is possible.

  An overhang plate portion 145 is formed on the box case 131. The overhang plate portion 145 is provided above the first insertion hole 138 and protrudes rearward from the box case 131. In a state where the substrate box 110 is attached to the movable base part 203, the board box 110 is located above the back plate part 231 of the movable base part 203 and protrudes to a position behind the back plate part 231. . With this configuration, by attaching the substrate box 110 to the movable base portion 203, the substrate box 110 is positioned above the portion extending from the locking plate 255 to the first insertion hole portion 138, and the box case 131 and the back plate portion 231. The gap portion can be covered from above the substrate box 110. Therefore, an unauthorized operation such as cutting a connecting pin 137 by inserting a cutter or a saw blade between the box case 131 and the back plate portion 231 can be prevented. Further, a through hole 145a is formed in the overhanging plate portion 145, and a protruding portion 253 is formed in the movable base portion 203 at a position corresponding to the through hole 145a. When the main control device 101 is attached to the movable base portion 203, the protruding portion 253 is engaged with the through hole 145a of the overhanging plate portion 145. With this configuration, even when the back plate portion 231 is urged away from the box case 131, the back plate portion 231 and the box case are engaged by the engagement of the protruding portion 253 and the through hole 145a. It is possible to prevent a gap from occurring between 131. Therefore, it is possible to further improve the effect of preventing an unauthorized operation such as cutting the connecting pin 137 by inserting a cutter or a saw blade between the box case 131 and the back plate portion 231 described above.

  In the configuration in which the main control device 101 is supported by the fixed base portion 202 so as to be able to rotate back and forth with the lower portion as a central axis, the socket 107 to which a cable connector connected to another device is connected is connected to the main control device 101. It is desirable to provide in the lower part, ie, the rotation center side. In such a case, it is difficult to arrange the connecting means for connecting the main control device 101 and the movable base portion 203 on the rotation center side. Therefore, when the connecting means for connecting the main control device 101 and the movable base portion 203 is disposed on the open end side, the connecting means is positioned on the near side when the movable base portion 203 is rotated forward. Compared with the case where the connecting means is provided on the rotation center side, it becomes easier to touch the connecting means, and there is a concern that it may be attempted to remove the connecting pin 137 illegally. However, in this configuration using the connecting means described above, the front end side locking claws 304 of the connection pins 137 are covered by the round hole portions 254b of the second insertion hole portions 254, so that the front end side locking claws 304 are engaged. Even if the stop state cannot be released, the connection pin 137 is removed from the first insertion hole 138 and the locking plate 255 by the locking of the proximal-side locking claw 305 and the first insertion hole 138 even if the locked state is released. It cannot be removed. Therefore, it is possible to suitably prevent fraud made to the main control device 101.

  Next, a second embodiment will be described with reference to FIGS.

  27 is a perspective view of the pedestal device 201, FIG. 28 is a perspective view of the connecting pin 437, FIG. 29 is a perspective view of the locking plate 455, FIG. 30 is a rear view of the locking plate 455, FIG. 32 is a cross-sectional view of the connecting means. Note that in the second embodiment, the same components as those in the first embodiment described above are denoted by the same reference numerals, or detailed descriptions thereof are omitted by omitting the reference numerals.

  As shown in FIGS. 28, 31, and 32, the shaft portion 302 of the connecting pin 437 has a distal end side locking claw 404 (second restricting portion) on the distal end side portion and the proximal end side portion of the shaft portion 302, respectively. A proximal end side locking claw 305 (third restriction portion) is provided. The distal end side locking claws 404 and the proximal end side locking claws 305 are provided in pairs, and the distal end side locking claws 404 are provided at positions separated from each other with the central axis of the shaft portion 302 interposed therebetween. The base end side locking claws 305 are also provided at positions separated from each other with the central axis of the shaft portion 302 interposed therebetween.

  The distal end side locking claw 404 includes an arm portion 404 a extending from the distal end of the shaft portion 302 along the axial direction of the shaft portion 302, and a claw portion protruding from the arm portion 404 a toward the radially outer side than the shaft portion 302. It has 404b (protrusion part).

  The arm portion 404a is formed so as to extend along the axial direction with a thickness substantially the same as the thickness of the shaft portion 302. The arm portion 404a is elastically deformed by applying a predetermined urging force so that the claw portion 404b is pivoted. The claw portion 404b can be returned to its original position by being moved toward the inside in the radial direction of the portion 302 and restored by disappearance of the urging force.

  The claw portion 404b is formed such that the outer surface of the claw portion 404b is inclined so as to gradually move toward the radially outer side of the shaft portion 302 as it moves from the distal end side to the proximal end side of the shaft portion 302. When the distal end portion of the connecting pin 437 is inserted into the opening hole 413 (the communication hole portion, see FIG. 30) of the locking plate 455, the arm portion 404a can be elastically deformed by coming into contact with the opening hole 413. It has become.

  As shown in FIGS. 31 and 32, the distal end side locking claws 404 extend in the same direction with the base end being a direction having a phase angle of 90 degrees from the direction in which the proximal end side locking claws 305 are separated from each other. Is formed.

  A second insertion hole 454 is formed in the movable base 203, and a locking plate 455 for locking the front end side locking claw 404 of the connecting pin 437 is attached to the second insertion hole 454. It has been.

  The locking plate 455 is made of a synthetic resin material such as polycarbonate having a predetermined rigidity. For example, as shown in FIGS. 29 and 30, the horizontally long flat plate portion 412 (main body portion) and the flat plate portion 412 It has an opening hole 413 that opens substantially in the center, and a pair of holding claws 415 (a locking portion and a locking claw portion) that protrude from the back surface of the flat plate portion 412 at both the left and right positions of the flat plate portion 412.

  The flat plate portion 412 has a flat plate shape having substantially the same thickness as the back plate portion 231 of the movable base portion 203. The radius of the opening hole 413 is set to be larger than the radius of the shaft portion 302 of the connecting pin 437 and smaller than the distance between the protruding end portions of the pair of claw portions 404a. The opening hole 413 is formed in a semicircular shape in which a half is cut out from the circular central line having the radius, and is not only opened in the central axis direction but also in the radial direction perpendicular to the central axis line. Are also opened in a specific direction (downward in the present embodiment).

  The holding claw 415 is for detachably holding the locking plate 455 in the second insertion hole portion 454 of the movable base portion 203, and an arm portion 415a extending substantially vertically from the back surface of the flat plate portion 412; A claw portion 415b that protrudes left and right from the flat plate portion 412 at the tip of the arm portion 415a is provided. The arm portion 415a is configured to move toward the center in the left-right direction, which is a direction in which the claw portions 415b approach each other by elastic deformation, and to return the claw portion 415b to its original position by restoration.

  Further, the flat plate portion 412 is provided with a locking portion 416 (communication hole portion) that locks the claw portion 404b of the front end side locking claw 404 so that the connection pin 437 cannot be moved in the pulling direction. A pair of left and right rotation restricting portions 418 for restricting the rotation of the connecting pin 437 is provided in cooperation with the second insertion hole 454 while being engaged with the engaging portion 416.

  The locking portion 416 has a semi-cylindrical shape that communicates with the opening hole 413 and protrudes from the back surface of the flat plate portion 412, and an inner diameter thereof is set to be approximately the same as the opening hole 413. Then, it is formed in a flat shape along the radial direction of the locking portion 416, and the claw portion 404 b of the front end side locking claw 404 is inserted by inserting the distal end side portion of the connecting pin 437 into the opening hole 413 of the flat plate portion 412. The base end of the claw portion 404b of the front end side locking claw 404 can be opposed to the front end of the locking portion 416 in a state of protruding rearward from the front end.

  Therefore, the connecting pin 437 is inserted into the opening hole 413 of the flat plate portion 412 so that the claw portion 404b of the front end side locking claw 404 protrudes rearward from the front end of the locking portion 416. When the 437 is to be moved from the distal end side of the connecting pin 437 toward the proximal end side, the proximal end of the claw portion 404b of the distal end side locking claw 404 is brought into contact with the distal end of the locking portion 416. The movement to the side to be pulled out can be prevented and locked.

  The pair of left and right rotation restricting portions 418 extend along the axial direction of the locking portion 416 from the tip of the locking portion 416. These rotation restricting portions 318 are set so that the pair of claw portions 304b of the connecting pin 437 are arranged on the notch side of the opening hole 413 from the rotation restricting portion 318.

  The locking plate 455 having the above configuration is detachably attached to the second insertion hole 454 provided in the movable base 203. The second insertion holes 454 are formed integrally with the back plate portion 231 of the movable base portion 203, and in the present embodiment, a total of four are arranged in a line on the left and right in the upper center of the back plate portion 231. Has been placed.

  The second insertion hole portion 454 is recessed from the front surface of the back plate portion 231 toward the back surface side, and when the locking plate 455 is attached, the surface of the flat plate portion 412 is the back plate portion of the movable base portion 203. It has the structure hold | maintained so that the surface of 231 may become flush | level.

  Since the configuration of the second insertion hole 454 is the same as that of the first embodiment, the description thereof will be omitted. However, as shown in FIG. 27, the opening of the second insertion hole 454 is formed on the locking plate 455. In addition to the rectangular portion corresponding to the flat plate portion 412, a semicircular portion continuous with the opening hole 413 is formed so that the flat plate portion 412 and the shaft portion 302 of the connecting pin 438 can be accommodated.

  In such a configuration, the tip side portion of the connecting pin 437 is inserted into the opening hole 413 of the flat plate portion 412, and the claw portion 404b of the tip side locking claw 404 projects rearward from the tip of the locking portion 416. When it is going to rotate toward the rotation direction one side or the rotation direction other side of the front end side locking claw 404, the front end side locking claw 404 is brought into contact with the rotation restricting portion 418 and the second insertion hole portion 454. Thus, the connecting pin 437 can be restricted from rotating.

  When the above-described connecting means is applied, when the bridging portion 139 of the body portion 332 where the connecting pin 437 is locked is cut with a tool such as a nipper, and the locking plate 455 is removed from the movable base portion 203. The movement of the connecting pin 437 restricted by the second insertion hole 454 to the notch side in the opening hole 413 is allowed. For this reason, if the connecting pin 437 is slid to the notch side with respect to the locking plate 455, the connecting pin 437 can be removed from the locking plate 455. Therefore, the operation of releasing the fitting of the first coupling piece 255a and the second coupling piece 255b as in the first embodiment is not necessary, and the coupling pin 437 can be removed from the locking plate 455 more easily. it can.

  Next, a third embodiment will be described.

  FIG. 33 is a perspective view of the connecting pin 537, FIG. 34 is a diagram illustrating the configuration of the first insertion hole 538, and FIG. 35 is a trunk portion of the first insertion hole 538 where the proximal end portion of the connection pin 537 is provided. It is a figure which shows the state latched by 332 by a partial cross section, and corresponds to FIG. Note that in the third embodiment, the same components as those in the above embodiments are denoted by the same reference numerals, or detailed descriptions thereof are omitted by omitting the reference numerals.

  As shown in FIG. 33, the connecting pin 537 is configured such that the distal end side locking claws 304 and the proximal end side locking claws 305 are arranged in a straight line in the axial direction of the shaft portion 302. That is, there is a positional relationship in which the direction in which the distal end side locking claws 304 are separated and the direction in which the proximal side locking claws 305 are separated form a phase angle of 0 degrees.

  A locking portion 536 is provided in the center hole 333 of the body portion 332 so that the claw portion 305b of the proximal end side locking claw 305 is hooked so that the connecting pin 537 cannot be pulled out from the body portion 332. ing.

  As shown in FIG. 34, the locking portions 536 project from the center hole 333 so as to be paired apart in the vertical direction. Of the end faces of the locking portions 536 located on both axial sides of the center hole 333, the rear end face located on the axial rear side of the center hole 333 is formed in a planar shape along the radial direction of the center hole 333. The base end side portion of the connecting pin 537 is inserted into the center hole 333 of the body portion 332 so that the claw portion 305b of the base end side locking claw 305 protrudes rearward from the rear end surface of the locking portion 536. In this state, the base end of the claw portion 305b of the base end side locking claw 305 can be opposed.

  Therefore, in a state where the base end side portion of the connecting pin 537 is inserted into the center hole 333 of the body portion 332 and the claw portion 305b of the base end side locking claw 305 protrudes rearward from the rear end surface of the locking portion 536. (See FIG. 35) When the connection pin 537 is moved from the distal end side toward the proximal end side of the connection pin 537 toward the proximal end side, the proximal end of the claw portion 305b of the proximal end side locking claw 305 is moved. It is possible to prevent movement toward the side to be pulled out by being brought into contact with the rear end surface of the locking portion 536.

  In the center hole 333 of the trunk portion 332, the base pin side locking claw 305 and the locking portion 536 are locked by rotating the connecting pin 537 relative to the first insertion hole 538. A passage portion 539 is provided as a base end side lock releasing means for releasing the.

  The passage portion 539 can move the connecting pin 537 without being caught by the claw portions 304b and 305b when trying to move the connecting pin 537 from the distal end side toward the proximal end side of the connecting pin 537. It can be done. The passage portion 539 forms a pair separated from each other in the center hole 333 in the left-right direction. The claw portion 305b has a width wider than the width of the claw portion 305b.

  Accordingly, in a state where the base end side portion of the connecting pin 537 is inserted into the body portion 332 and the claw portion 305b of the base end side locking claw 305 protrudes in the axial direction of the center hole 333 from the rear end surface of the locking portion 536. The coupling pin 537 is rotated relative to the body portion 332 so that the phases of the claw portion 305b and the passage portion 539 coincide with each other so that the claw portion 305b faces the rear end surface of the locking portion 536. It can be canceled. Then, by moving the connecting pin 537 as it is to the drawing side, the claw portion 305b can be passed through the passage portion 539 and pulled out from the trunk portion 332.

  Further, subsequently, by moving the connecting pin 537 to the side to be pulled out, the claw portion 304b can be passed through the passage portion 539 and pulled out from the trunk portion 332.

  Even in such a configuration, as in the first embodiment, in the state where the first insertion hole 538 and the locking plate 255 are connected by the connection pin 537, the second insertion hole 254 is temporarily provided. Even if the round hole 254b is cut and the locking between the distal end side locking claw 304 and the locking plate 255 is released, the connection pin is locked by the locking between the proximal side locking claw 305 and the first insertion hole 538. It is possible to restrict the movement of 537 to the drawing side, and it is possible to prevent the connection pin 537 from being removed from the first insertion hole 538 and the locking plate 255. Therefore, it is possible to prevent the main control device 101 and the movable base portion 203 from being illegally separated and performing an illegal act on the main board 105.

  Further, as compared with the first embodiment, it is not necessary to rotate the connecting pin 537 after the base end side portion of the connecting pin 537 is pulled out from the body portion 332, and the connecting pin 537 can be pulled out as it is. Removal from the portion 332 can be performed more easily.

  While the window portion 302a is formed in the shaft portion 302 and the proximal end side locking claw 305 is provided at the portion, the direction in which the distal end side locking claw 304 is separated from the direction in which the proximal side locking claw 305 is separated is 0. It has a configuration having a positional relationship that is a phase angle of degrees. By adopting such a configuration, even when the proximal end side locking claw 305 and the distal end side locking claw 304 are arranged in a straight line, the proximal side locking claw 305 and the distal end side locking claw 304 Can be bent independently. Therefore, even if one of the locking claws is bent flexibly by any method, the locking state of the other locking claw can be maintained, and the connecting pin 537 is connected to the first insertion hole 538 and the locking plate 255. Can be prevented from being illegally removed.

  Next, a fourth embodiment will be described.

  36 is a perspective view of the locking plate 655, FIG. 37 is a rear view of the locking plate 655, FIG. 38 is a perspective view of the box case 131, and FIG. 39 illustrates the configuration of the first insertion hole 638. 40 is a diagram for explaining a coupling state between the coupling pin 137 and the locking plate 655, and FIG. 41 is a diagram showing a coupling state between the coupling pin 137 and the first insertion hole 638 in a partial cross section. . Note that in the third embodiment, the same components as those in the above embodiments are denoted by the same reference numerals, or detailed descriptions thereof are omitted by omitting the reference numerals.

  In the first embodiment described above, the rotation restricting portion 318 provided on the locking plate 255 restricts the rotation of the connecting pin 137 to one side in the rotation direction and the other side in the rotation direction. However, in the fourth embodiment, The locking plate 655 is provided with a rotation restricting portion 618 for restricting rotation of the connecting pin 137 in one direction of rotation, and the rotation restricting portion 640 for restricting rotation of the connecting pin 137 in the other direction of rotation is provided in the first insertion hole. Provided in the portion 638.

  The locking plate 655 has a pair of rotation restricting portions 618 as shown in FIGS. Each rotation restricting portion 618 extends from the distal end of the locking portion 316 along the axial direction of the locking portion 316 and is spaced apart in the radial direction of the locking portion 316 to form a pair. One of the rotation restricting portions 618 is provided at an oblique upper position on one side in the horizontal direction of the flat plate portion 312 and the other is provided at an oblique lower position on the other side in the horizontal direction via the central axis of the locking portion 316. ing.

  As shown in FIG. 40, the distal end portion of the connecting pin 137 is inserted into the opening hole 313 of the flat plate portion 312, and the claw portion 304 b of the distal end side locking claw 304 protrudes rearward from the distal end of the locking portion 316. And each claw part 304b has the opposing part which respectively opposes the one rotation direction one side of each front end side latching claw 304 in the state where it separated and arranged up and down.

  Therefore, when the connecting pin 137 is to be rotated toward one side in the rotational direction, the distal end side locking claw 304 is placed on the opposite portion of the rotation restricting portion 618 in a state where the claw portion 304b is spaced apart vertically. The connection pin 137 can be regulated so as not to rotate to one side in the rotational direction by abutting.

Each rotation restricting portion 640 protrudes in the center hole 333, and one is provided at an oblique upper position on one side in the lateral direction of the box case 131 with the central axis of the locking portion 336 interposed therebetween. The other is provided at a diagonally lower position on the other side in the direction. As shown in FIG. 38 in particular, the rotation restricting portion 640 is configured by causing a part of the rear end surface of the locking portion 336 to protrude rearward through a step.

  As shown in FIG. 41, the base end side portion of the connecting pin 137 is inserted into the center hole 333 of the trunk portion 332 so that the claw portion 305b of the base end side locking portion 305 is more than the rear end surface of the locking portion 336. In the state which protrudes back and each nail | claw part 305b is spaced apart from right and left, it has the opposing part 639 which each opposes along the rotation direction other side of each nail | claw part 305b.

  Therefore, when the connection pin 137 is to be rotated toward the other side in the rotation direction, the base end side locking claw 305 is brought into contact with the facing portion 639 in a state where the claw portion 305b is spaced apart from the left and right. Thus, the connection pin 137 can be restricted so as not to rotate toward the other side in the rotation direction.

  Therefore, the base end side portion of the connecting pin 137 is inserted and locked into the center hole 333 of the body portion 332, and the distal end side portion of the connecting pin 137 is inserted into the opening hole 313 and the locking portion 316 of the locking plate 655. In the locked state (see FIGS. 40 and 41), the rotation of the connecting pin 137 to one side in the rotation direction or the other side in the rotation direction can be restricted.

As a result, the main controller 101 is restricted from moving in the left-right direction by the engagement of the locking wall 1253 and the first groove 1201 and the engagement of the second locking wall 1254 and the second groove 1202. It becomes.

  A first return plate portion 1251 a and a second return plate portion 1251 b are formed on the upper end portion of the box case 131. When the main control device 101 is mounted on the movable base portion 203, both the return plate portions 1251a and 1251b are located above the back plate portion 231 of the movable base portion 203, and the rear surfaces of the both return plate portions 1251a and 1251b. Is positioned in the same plane as the rear surface of the back plate portion 231 of the movable base portion 203. For this reason, the contact surfaces of the box case 131 of the main controller 101 and the back plate portion 231 of the movable base portion 203 in the front-rear direction (that is, the insertion direction of the connecting pin 137) are covered from above by the both return plate portions 1251a and 1251b. Will be. As a result, a cutter, a saw blade, or the like is inserted between the box case 131 and the back plate portion 231 to cut the connection pin 137 itself, or the back plate portion 231 is bent rearward so that the first insertion hole portion 138 is inserted. And a gap between the second insertion hole 254 (locking plate 255) and the second insertion hole 254 can be prevented. Further, the second protruding wall portion 1253b formed at the distal end portion of the locking wall portion 1253 and the extending wall portion 1255 formed at the distal end of the second locking wall portion 1254 are the back plate of the movable base portion 203. It is located behind the part 231. As a result, the back plate portion 231 of the movable base portion 203 is sandwiched between the box cases 131 in the front-rear direction, and is restricted from bending in the front-rear direction. Therefore, it is possible to prevent the back plate portion 231 from being bent rearward so that a gap is generated between the first insertion hole portion 138 and the second insertion hole portion 254 (locking plate 255). Further, a notch 1256 that is tapered from the front surface side to the rear surface side of the extending wall portion 1255 and having a sharpened tip is formed at the proximal end portion of the extending wall portion 1255. For this reason, if the back plate portion 231 is bent backward by some method, an external force is applied to the extending wall portion 1255 and stress is concentrated on the tip of the notch portion 1256. When an excessive external force is applied to the back plate portion 231 and the back plate portion 231 is bent backward by a specific distance, a whitening line is generated from the front end of the notch portion 1256 toward the rear surface of the extended wall portion 1255, and the second longer than the specific distance. When bent more than a specific distance, the extended wall portion 1255 is broken from the tip of the notch portion 1256 or bent backward. By the way, in the present embodiment, a whitening line is generated when the distance between the rear surface of the first insertion hole 138 and the front surface of the locking plate 255 reaches 2 mm, and when the distance is 5 mm or more, breakage or bending occurs. ing.

  Overhang plate portions 1252 are formed on both return plate portions 1251a and 1251b of the box case 131, and locking wall portions 1253 and second locking wall portions 1254 ( An extension wall portion 1255) is formed. When the main control device 101 is attached to the movable base portion 203, the overhanging plate portion 1252 is positioned above the second insertion hole portion 254, and the locking wall portion 1253 and the second locking wall. The extended wall portion 1255 formed at the tip of the portion 1254 is positioned on both the left and right sides of the second insertion hole 254. The overhanging plate portion 1252 and the locking wall portion 1253 are arranged so that the front end surface thereof is located behind the rear surface of the second insertion hole portion 254 when the main controller 101 is attached to the movable base portion 203. The width is set. For this reason, more specifically, the locking portion between the second insertion hole 254 and the locking plate 255 is covered by the overhanging plate portion 1252 and the locking wall 1253 than the second insertion hole 254. As a result, it is possible to prevent an injustice in which a tool or the like is inserted from above the movable base portion 203 or the vicinity of the locking portion 252 and the locking state between the second insertion hole 254 and the locking plate 255 is released. The second locking wall portion 1254 and the extending wall portion 1255 are positioned forward of the back and forth widths of the return plate portions 1251a and 1251b from the rear surface of the overhanging plate portion 1252, so that the movable base portion When viewed from the side wall 233 side of 203, a part of the second insertion hole 254 is exposed. However, the fixed base portion 202 of the base device 201 is provided with a flange piece 218 (see FIG. 44). For this reason, in the standing posture state, the flange piece 218 can prevent a tool or the like from being inserted in the vicinity of the second insertion hole portion 254 from the side of the movable base portion 203.

  In the sixth embodiment described in detail above, the following excellent effects are obtained in addition to the effects in the first embodiment.

  A through hole 145a is formed in the overhanging plate portion 1252, and a protruding portion 253 is formed in the movable base portion 203 at a position corresponding to the through hole 145a. When the main control device 101 is mounted on the movable base portion 203, the protruding portion 253 is inserted into the through hole 145a of the projecting plate portion 1252. With this configuration, even when the back plate portion 231 is urged away from the box case 131, the back plate portion 231 and the box case are engaged by the engagement of the protruding portion 253 and the through hole 145a. It is possible to prevent a gap from occurring between 131. Therefore, a cutter or a saw blade is inserted between the box case 131 and the back plate portion 231 to cut the connecting pin 137, or the back plate portion 231 is bent rearward so that the first insertion hole portion 138 and the first insert hole portion 138 It is possible to prevent an unauthorized operation such as releasing the locking state between the connecting pin 137 and the locking plate 255 after creating a gap between the two insertion holes 254 (the locking plate 255).

  However, when, for example, an excessive external force is applied so that the engagement between the protruding portion 253 and the through hole 145a is released and the back plate portion 231 is bent away from the box case 131, the engagement with the connecting pin 137 is stopped. There is a possibility that the locked state of the plate 255 may be illegally released. When the unauthorized release is made, the bridging portion 139 that connects the first insertion hole 138 and the main control device 101 is not cut, and the connecting pin 137 can be reused. However, there will be no trace and it will be difficult to find fraud.

  Therefore, the box case 131 is formed with the second protruding wall portion 1253b and the extending wall portion 1255. When the box case 131 is attached to the movable base portion 203, the second protruding wall portion 1253b and the extending wall portion are formed. 1255 is positioned behind the back plate portion 231 of the movable base portion 203. With this configuration, the back plate portion 231 of the movable base portion 203 can be sandwiched between the box cases 131 in the front-rear direction, and bending in the front-rear direction can be restricted.

  In the box case 131, an overhanging plate portion 1252 that protrudes rearward is formed at a position above the first insertion hole 138. Then, a locking wall portion 1253 and a second locking wall portion 1254 are formed at both ends of each overhanging plate portion 1252, and a second protruding wall portion 1253 b and an extending wall are formed at the tips of both locking wall portions 1253 and 1254. Part 1255 was formed. With this configuration, the second protruding wall portion 1253b and the extending wall portion 1255 can be positioned in the vicinity of the second insertion hole portion 254 in a state where the main control device 101 is mounted on the movable base portion 203. . As a result, it is possible to suitably restrict the portion of the back plate portion 231 where the second insertion hole 254 is formed from being bent backward.

  At the base end portion of the extending wall portion 1255, a notch portion 1256 that is tapered from the front surface side to the rear surface side of the extending wall portion 1255 and has a sharp tip is formed. With this configuration, if the back plate portion 231 is bent backward by some method, an external force is applied to the extending wall portion 1255 and stress can be concentrated on the tip of the notch portion 1256. As a result, for example, when an excessive external force is applied so that the engagement between the protruding portion 253 and the through hole 145a is released and the back plate portion 231 is bent away from the box case 131, the extending wall portion A whitening line can be generated in 1255, or a deformation such as a break or a bend can be generated, and a trace can be left in the case of the unauthorized release. Therefore, it can suppress that the said fraud is made, and can discover easily when the said fraud is made.

  The second locking wall portion 1254 is formed on the overhanging plate portion 1252, and the extending wall portion 1255 is formed not with the overhanging plate portion 1252 but with the second locking wall portion 1254. By adopting such a configuration, when the extended wall portion 1255 undergoes deformation such as breakage or bending, the extension plate portion 1252 undergoes deformation such as breakage or bending in addition to the extension wall portion 1255. Can be prevented.

  The movable base portion 203 was integrally formed of a transparent synthetic resin material such as polycarbonate, and the extending wall portion 1255 was disposed at a position where it did not overlap the first insertion hole 138 and the bridging portion 139 in the front-rear direction. With this configuration, in a state where the main control device 101 is mounted on the movable base 203, the wall portion 1255 extending from the front of the slot machine 10 without changing the main control device 101 from the standing posture state to the tilting posture state. Can be visually recognized. Therefore, it is possible to facilitate the operation of confirming whether or not an improper trace is left on the extending wall 1255. Further, when the main control device 101 is in the tilted posture state, the back surface of the main control device 101 (that is, the back surface of the main substrate 105) can be visually recognized through the movable base 203. Therefore, it is possible to confirm whether the main control device 101 has been tampered with without removing the main control device 101 from the movable base 203.

  A first return plate portion 1251a and a second return plate portion 1251b were formed in the box case 131. Both return plate portions 1251a and 1251b are provided at the upper end portion of the box case 131, and protrude rearward from the box case 131. When the main control device 101 is mounted on the movable base portion 203, the two return plate portions 1251 a and 1251 b are positioned above the back plate portion 231 of the movable base portion 203, and the rear surface is the back plate of the movable base portion 203. It is located in the same plane as the rear surface of the portion 231. With this configuration, the joint portion between the box case 131 and the back plate portion 231 can be covered from above by the both return plate portions 1251a and 1251b. Therefore, a cutter or a saw blade is inserted between the box case 131 and the back plate portion 231 to cut the connecting pin 137 itself, or the back plate portion 231 is bent backward to form the first insertion hole portion 138. It is possible to prevent a gap from being generated between the second insertion hole 254 (the locking plate 255) and the like.

  The box case 131 is formed with an extension plate portion 1252 extending toward the movable base portion 203, and the locking wall portion 1253 and the second locking wall portion 1254 (extension wall) are provided at both ends of the extension plate portion 1252. Part 1255). When the main control device 101 is attached to the movable base portion 203, the overhanging plate portion 1252 is positioned above the second insertion hole portion 254, and the locking wall portion 1253 and the second locking wall. The extended wall portion 1255 formed at the tip of the portion 1254 is positioned on both the left and right sides of the second insertion hole 254. Further, when the main control device 101 is mounted on the movable base portion 203, the protruding plate portion 1252 and the locking wall portion 1253 are arranged so that the front end surface thereof is located behind the rear surface of the second insertion hole portion 254. The front-rear width was set. With this configuration, the second insertion hole 254 and the locking part of the locking plate 255 are covered with the overhanging plate part 1252 and the locking wall part 1253 in more detail than the second insertion hole 254. Become. As a result, it is possible to prevent an injustice in which a tool or the like is inserted from above the movable base portion 203 or the vicinity of the locking portion 252 and the locking state between the second insertion hole 254 and the locking plate 255 is released.

  Further, when the main controller 101 is attached to the movable base 203, the front and rear widths of the overhanging plate portion 1252 are set so that the front end surface is located behind the rear surface of the second insertion hole 254. Thus, the back plate portion 231 can be bent rearward, and the fraud in which the locking state of the connecting pin 137 and the locking plate 255 is released from the gap between the back plate portion 231 and the box case 131 generated at this time can be prevented. Even if the back plate portion 231 is bent backward to create a gap between the back plate portion 231 and the box case 131, the gap can be covered from above by the overhang plate portion 1252, and a tool or the like can be placed in the gap. This is because it can be prevented from being inserted.

  The movable base portion 203 is formed with a locking portion 252, a through hole 145 a is formed in the locking portion 252, and a protruding portion 146 is formed in the box case 131. When the main control device 101 is mounted on the movable base 203, the protrusion 146 is inserted into the through hole 252a. With this configuration, it is possible to regulate the movement of the main control device 101 in the vertical direction with a relatively simple configuration.

  On the other hand, in such a configuration, when the main control device 101 is removed from the movable base portion 203, it is necessary to release the locking state between the projection 146 and the through hole 252a, and the movable base portion 203 and the box case 131 are repeatedly used. For this purpose, it is necessary to make the locking portion 252 elastically deformable in the front-rear direction. Therefore, the first groove portion 1201 is formed in the back plate portion 231 of the movable base portion 203, and the ribs are not arranged on the back plate portion 231. With this configuration, the locking portion 252 can be easily elastically deformed, and the work for mounting and removing the main control device 101 on the movable base 203 can be facilitated.

  However, when the first groove portion 1201 is formed in the back plate portion 231 of the movable base portion 203 and the rib is not arranged in the back plate portion 231, the second insertion hole portion 254 is formed at the same end as the locking portion 252. Therefore, the back plate portion 231 is bent backward to easily create a gap between the first insertion hole portion 138 of the main controller 101 and the second insertion hole portion 254 of the movable base portion 203. It becomes possible. Therefore, if an extension wall portion 1255 is formed in the box case 131 and the extension wall portion 1255 is whitened or deformed when the gap is generated, a fraud is temporarily made. Even so, it can be easily discovered.

  By the way, a rib is formed on the rear surface of the back plate portion 231, and the back plate portion 231 is bent backward so that the gap between the first insertion hole portion 138 of the main control device 101 and the second insertion hole portion 254 of the movable base portion 203. It is also possible to make it difficult to create a gap in the surface. However, even if it is a case where it is such a structure, it is difficult to make it the structure which does not bend the backplate part 231 to the front-back direction, and the concern that fraud is performed using the slightly produced gap cannot be wiped off. Further, since the rigidity of the locking portion 252 can be improved, there is a concern that the operation of mounting the main controller 101 on the movable base portion 203 and the operation of removing it may become complicated. Therefore, the ribs are not formed on the rear surface of the back plate portion 231, and the above-mentioned concerns are solved in a suitable manner by forming the extended wall portion 1255 on the box case 131 where the trace remains if fraud is made. can do.

  In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows.

  (1) In the first embodiment, the second insertion hole portion 254 having the round hole portion 254b is formed in the movable base portion 203, and the front-end-side locking claw of the connecting pin 137 is formed in the second insertion hole portion 254. In the configuration in which the locking plate 255 that locks 304 is attached, the first insertion hole 138 and the locking plate 255 are connected using the connecting pin 137 having the base end side locking claw 305. The two insertion holes 254 need not be formed. If the second insertion hole 254 is not formed, the distal end side locking claws 304 are exposed on the rear surface side of the movable base portion 203, so that the locked state between the distal side locking claws 304 and the locking plate 255 is released. Although there are concerns about fraud, even if the locking state between the distal end side locking claw 304 and the locking plate 255 is released, the proximal end side locking claw 305 and the first insertion hole 138 are connected by locking. The movement of the pin 137 to the drawing side can be restricted. Therefore, even if it is a case where it is such a structure, it can prevent that the connection pin 137 is removed from the 1st insertion hole part 138 and the latching plate 255. FIG. The same applies to other embodiments.

  (2) In the first embodiment, the first insertion hole 138 has the locking claw 336 that locks with the proximal-side locking claw 305, and the claw 305 b of the proximal-side locking claw 305. For example, the flat plate portion 312 of the locking plate 255 is positioned behind the back plate portion 231 of the movable base portion 203, and the claw portion 305b is on the movable base portion 203 side. It is good also as a structure accommodated in. In such a configuration, for example, if the claw portion 305b of the proximal end side locking claw 305 is locked to the rear end surface of the first insertion hole portion 138, the locking claw portion 336 is provided in the first insertion hole portion 138. This is unnecessary, and the shape of the first insertion hole 138 can be simplified. However, in such a configuration, a gap is formed between the first insertion hole portion 138 and the movable base portion 203, and fraud is caused by elastically deforming the locking claw portion 305 from the clearance toward the locking release side. There is concern about the possibility of The same applies to other embodiments.

  (3) In the first embodiment, the configuration in which the distal end side locking claws 304 and the proximal end side locking claws 305 have a phase angle of 90 degrees and the configuration in the same phase have been described. However, the phase angle is arbitrary.

  (4) In the first embodiment, the claw portion 304b of the distal end side locking claw 304 is configured to protrude radially outward from the arm portion 304a than the shaft portion 302. It is good also as a structure which protrudes toward the radial inside rather than the axial part 302. FIG. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said 1st Embodiment. The same applies to other embodiments.

  (5) In the first embodiment, the case where the distal end side locking claws 304 and the proximal end side locking claws 305 have the same radial size has been described. However, the present invention is not limited to this configuration. The size is arbitrary. For example, the front end side claw 304 may be formed so that the size between the radially outer ends of the claw portions 304b is the same diameter as the outer diameter of the shaft portion 302 or smaller than the shaft portion 302. . In such a configuration, for example, when the connecting pin 137 inserted into the central hole 333 of the trunk portion 332 is moved to the drawing side and the tip side portion of the connecting pin 137 is passed, The nail | claw part 304b can be made to pass without being caught by the latching | locking part 336, and the removal of the connection pin 137 can be performed easily. The same applies to other embodiments.

  (6) In the first embodiment, the connecting pin 137 has the cylindrical shaft portion 302. However, the present invention is not limited to this configuration, and the connecting pin 137 may have a rectangular cylindrical shaft portion. It is good and it is good also as a structure which has an octagonal cylindrical axial part. Needless to say, the first insertion hole 138 and the communication hole of the locking plate 255 may have a shape corresponding to the shape of the connection pin 137. However, when the first insertion hole 138 is removed from the connection pin 137, the first insertion hole 138 is configured to rotate the connection pin 137 so that the phases of the distal end side claw 304 and the passage portion 339 coincide with each other. It is desirable that the shape of the portion 138 be cylindrical regardless of the shape of the shaft portion. The same applies to the third to fifth embodiments.

  (7) In the first embodiment, a plurality of second insertion holes 254 are formed in the movable base 203, and a locking plate 255 is prepared in advance in each second insertion hole 254. However, in a configuration in which the locking plate 255 can be separated from the movable base 203 and the connecting pin 137 without destroying the locking plate 255, like the connecting pin 137, the locking plate 255 is inserted into one second insertion hole 254. It is good also as a structure which only prepares and uses the latching plate 255 repeatedly. If the locking plate 255 is reused, it is possible to reduce the number of parts of the movable base portion 203 and to prevent the conventional fraud, for example, the connecting pin 137 in the connected state, the locking plate 255. After the connection with the first insertion hole 138 is released, the unused locking plate 255 is again locked with the same second insertion hole 254, and the connection between the movable base 203 and the board box 110 is still released. If not, it can prevent fraudulent camouflage. The same applies to other embodiments.

  (8) In the first embodiment, the configuration in which the locking plate 255 is formed by the two coupling pieces 255a and 255b has been described, but it may be configured by three or more coupling pieces, It is good also as a structure formed with one member. However, when the locking plate 255 is formed of one member, when the connecting pin 137 is removed from the locking plate 255, the distal end side locking claws 304 are elastically deformed toward the mutually approaching side, Since it is necessary to remove the connecting pin 137 after releasing the locking state of the locking plate 255, the removal becomes somewhat difficult as compared with the above embodiments. In addition, even when the locking plate is formed of three or more coupling pieces, the separation step of separating the coupling pieces when removing the connecting pin 137 from the locking plate 255 increases. Removal may be somewhat complicated as compared with the above embodiments. The same applies to other embodiments.

  (9) In the first embodiment, the base-side latching claw 305 is provided on the connecting pin 137, but the second insertion hole 254 having the round hole 254b is formed on the movable base 203. A configuration in which a locking plate 255 that locks the front end side locking claw 304 of the connecting pin 137 is attached to the second insertion hole 254, that is, the locking state of the front end side locking claw 304 and the locking plate 255 is set to the rear side. In the configuration that can be covered from the base end, the base end side claw 305 may not be formed. This is because it is difficult to release the locked state because the locked state between the front end side locking claw 304 and the locking plate 255 is not exposed from the rear side. The same applies to other embodiments.

  (10) In the first embodiment, the two coupling pieces 255a and 255b are fitted to form the locking plate 255. However, the present invention is not limited to such a configuration. It is good also as a structure which adhere | attaches a piece, and it is good also as a structure which couple | bonds two coupling pieces using fasteners, such as a screw | thread. The same applies to other embodiments.

  (11) In the first embodiment, the fitting portions of the coupling pieces 255a and 255b are fitted in a direction perpendicular to the direction in which the holding claws 315 extend. It is good also as a structure fitted in the same direction. However, in such a configuration, there is a concern that the coupling pieces 255a and 255b may be separated when the locking plate 255 is attached to the second insertion hole 254. The same applies to the third to fifth embodiments.

  (12) In the first embodiment, the coupling pieces 255a and 255b are joined to form the locking plate 255 and then attached to the second insertion hole 254. However, the construction is changed. That is, each coupling piece does not have a coupling part that couples to each other, but has only a locking part that can be locked with the second insertion hole. Then, each coupling piece is individually attached to the second insertion hole, and the shape of the locking plate is formed in the second insertion hole. That is, the coupling plate is not directly coupled to form the locking plate, but the coupling plate is formed by interposing the second insertion hole in the coupling of the coupling pieces. It is good also as a structure which couple | bonds together and forms a latching plate. Even if it is a case where it is set as this structure, it is possible to show | play the effect similar to the said 1st Embodiment. However, in the case of such a configuration, it is necessary to individually attach each coupling piece to the second insertion hole portion, so that the attachment work and the removal work can be complicated as compared with the first embodiment. There is sex. The same applies to the third to fifth embodiments.

  (13) In the first embodiment, the structure in which the locking plate 255 is vertically divided into two at the center line in the left-right direction has been described. It is good also as a structure divided into 2 by the diagonal. Further, the configuration is not limited to the configuration in which the locking plate 255 is divided symmetrically to form the coupling piece, and the coupling piece may be formed by asymmetrical division. The same applies to the third to fifth embodiments.

  (14) In the second embodiment, by forming the semicircular opening hole 413 in the locking plate 455, the locking plate 455 connected to the connecting pin 437 is removed from the second insertion hole 454. In this case, the connection pin 437 can be moved to the opening side different from the central axis direction of the opening hole 413. That is, it is possible to move the connecting pin 437 to the opening side of the locking plate 455 by forming an opening having a width that is larger than the outer diameter of the shaft 302 of the connecting pin 437 in the locking plate 455. Although configured, an opening having a width smaller than the outer diameter of the shaft 302 of the connecting pin 437 may be formed in the locking plate 455. Even in such a configuration, the shaft portion 302 of the connecting pin 437 is predetermined at intervals equal to or smaller than the width of the opening when the shaft portion 302 of the connecting pin 437 is viewed from the central axis direction. If the structure has opposing sides extending in the direction, at least the opening and the opposing sides coincide after the locking plate 455 connected to the connecting pin 437 is removed from the second insertion hole 454. Thus, the connecting pin 437 can be removed from the opening by rotating the connecting pin 437. However, in the case of such a configuration, there is a possibility that a step of rotating the connecting pin 437 may be required as compared with the third embodiment.

  (15) In the third embodiment, the opening of the second insertion hole 434 corresponds to the flat plate portion 412 so that the flat plate portion 412 of the locking plate 455 and the shaft portion 302 of the connecting pin 438 can be accommodated. In addition to the rectangular portion, a configuration having a semicircular portion continuous with the opening hole 413 is used, but it goes without saying that a configuration without the semicircular portion may be used.

  (16) In the sixth embodiment, the extension wall portion 1255 is formed in the box case 131 and the improper trace remains on the extension wall portion 1255. It is good also as a structure in which a trace remains.

  For example, the vertical length of the protruding portion 253 of the movable base portion 203 is set to such a length that the engagement with the through hole 145a cannot be released even if the back plate portion 231 is bent toward the side away from the box case 131. In such a configuration, when the back plate portion 231 is bent toward the side away from the box case 131 in order to release the engagement, a whitening line is generated at the base end portion of the protruding portion 253, or the breakage, the bending, or the like is performed. Can be generated, and when the above-described unauthorized release is made, the trace can be left.

  (17) In the sixth embodiment, the extending wall portion 1255 is formed in the box case 131 and the improper trace remains on the extending wall portion 1255. However, from the front side of the main controller 101, It is good also as a structure which affixes the sealing seal | sticker which the trace remains when it peels so that it may extend over the rear surface side of the movable base part 203. FIG. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said 6th Embodiment.

  (18) In the sixth embodiment, the notch 1256 is formed at the base end of the extending wall 1255. However, it may not be formed. However, when the cutout portion 1256 is not formed, it is desirable to shorten the front-rear width of the extended wall portion 1255 or increase the vertical length.

  (19) In the sixth embodiment, the shape of the notch 1256 is tapered and the tip is pointed. However, the shape is not limited to this configuration, and the shape is arbitrary.

  (20) The front-rear width and the upper-lower length of the extending wall portion 1255 in the sixth embodiment are arbitrary. When the front / rear width is set shorter or the upper / lower length is set longer, the rigidity of the extending wall portion 1255 is reduced, so that compared to the case where the back plate portion 231 of the movable base portion 203 is bent backward. It becomes possible to leave the trace at an early stage. Conversely, when the front / rear width is set to be long or the vertical length is set to be short, the rigidity of the extending wall portion 1255 is improved, so that the back plate portion 231 of the movable base portion 203 is bent backward. Can be suitably suppressed.

  (21) In the sixth embodiment, the second locking wall portion 1254 is formed on the overhanging plate portion 1252, and the extending wall portion 1255 is formed from the second locking wall portion 1254. It is good also as a structure which does not form the 2nd locking wall part 1254 but forms the extended wall part 1255 from the overhang | projection board part 1252. FIG. Even if it is the case where it is such a structure, if it is set as the structure which forms a notch part in the boundary part of the overhang | projection board part 1252 and the extension wall part 1255, there exists an effect similar to the said 6th Embodiment. Is clear.

  (22) In the sixth embodiment, the through hole 145a is formed in the overhanging plate portion 1252, and the protruding portion 253 is formed in the movable base portion 203. However, a configuration without these may be used. However, in the case of such a configuration, there is a possibility that the back plate portion 231 is bent rearward, and thus it is necessary to sufficiently secure the front-rear width of the protruding plate portion 1252. By sufficiently securing the front and rear width of the overhanging plate portion 1252, even if the back plate portion 231 is bent backward, it occurs between the first insertion hole portion 138 and the locking plate 255. The gap can be covered from above by the overhanging plate portion 1252. As a result, a tool or the like can be prevented from being inserted into the gap, and the locking state between the connecting pin 137 and the locking plate 255 can be prevented from being released.

  (23) In the sixth embodiment, the movable base portion 203 is provided with the locking portion 252, the through-hole 252 a is formed in the locking portion 252, and the protruding portion 146 is formed in the box case 131. In the state where the main control device 101 is mounted on the movable base portion 203, the protrusion 146 is inserted into the through hole 252a, and the vertical movement of the main control device 101 is restricted. However, it is good also as a structure which does not have these structures. When the movable base portion 203 is not provided with the locking portion 252, the first groove portion 1201 is not necessary. Therefore, the movable base portion 203 is provided with the second groove portion 1202 at a position corresponding to the first groove portion 1201 in the sixth embodiment, or the groove portion itself is not disposed. The box case 131 is provided with a second locking wall 1254 and an extending wall 1255 in place of the locking wall 1253 at a position corresponding to the locking wall 1253. In the case of such a configuration, the four extending wall portions 1255 are positioned behind the back plate portion 231, so that an improper trace can be left more reliably.

  (24) In the sixth embodiment, the rib is not provided on the rear surface of the back plate portion 231 of the movable base portion 203. However, the rib may be provided. However, in consideration of workability when removing the main control device 101 from the movable base portion 203, it is desirable not to provide ribs at least in the vicinity of the locking portion 252.

  (25) In the sixth embodiment, the extended wall portion 1255 is formed in the box case 131, but the extended wall portion 1255 may be formed in the box cover 111. For example, a leg portion that extends rearward from the upper end of the box cover 111 and has a front and rear length straddling the box case 131 and the back plate portion 231 is formed, and an extending wall portion 1255 is formed downward from the tip of the leg portion. Form. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said 6th Embodiment.

  Further, the extending wall portion 1255 may be formed on the movable base portion 203. For example, the extending wall portion 1255 is formed so as to extend from the front end portion of the side wall portion 233 to the main control device 101 side. In the case of such a configuration, when an external force is applied to the main control device 101 in a direction separating the main control device 101 from the movable base portion 203 (that is, forward), the trace can be left. Become.
