Description

  The present invention relates to a gaming machine such as a slot machine.

  The gaming machine has a control board for controlling game contents and the like. The control board is an important part that controls the entire game, and is housed in the casing of the gaming machine in a state of being enclosed in a board box in order to prevent unauthorized modification.

  For example, as shown in Patent Documents 1 and 2, since the maintenance / management work of the control board is necessary, the board box is detachably held in the housing via the pedestal device. It can be removed from the pedestal device as required.

  The board box is made of a transparent resin material so that the control board can be seen. Then, there is a problem that the control board is illegally removed from the pedestal device and taken out of the housing, replaced with an unauthorized control board, or the control board is illegally modified. It is fixed to the device.

  Such a problem is not limited to the above-described relationship between the board box and the pedestal device (first member and second member). For example, the front case body and the back case body (first member and second member) constituting the board box. ) And the like, when two members are combined.

  The fixing means includes a through-hole drilled in the board box so that the central axis extends in a direction perpendicular to the sliding direction, and a pedestal device that extends coaxially with the through-hole and communicates with the through-hole. In this communication hole, a fixing pin is inserted from the substrate box side toward the pedestal device side to prohibit sliding movement of the substrate box relative to the pedestal device, and the substrate box is fixed to the pedestal device. The fixing pin is provided with a locking claw, and the distal end portion of the fixing pin is inserted into the communication hole of the pedestal device, and the proximal end portion of the fixing pin is inserted into the through hole of the board box. It can be stopped.

  Here, for example, when the locking claw is provided at the base end portion of the fixing pin, the base end side portion of the fixing pin is locked to the board box by insertion of the fixing pin, but the tip end portion is connected to the communication hole. It is only inserted and not locked to the pedestal device. Therefore, when the substrate box and the pedestal device are urged so as to be separated from each other in a direction perpendicular to the sliding direction, a gap can be generated between the substrate box and the pedestal device, and locked from the gap at the rotation position. The nail can be released.

  Moreover, when the latching claw is provided in the front-end | tip part of a fixing pin, the front-end | tip part of a fixing pin is latched by the base apparatus by insertion of a fixing pin. In such a locked state, when the substrate box is in the accommodation position, the substrate box and the back plate of the housing are opposed to each other, and the front end portion of the fixing pin can be hidden from the outside, but is in the rotational position. When the back side of the board box is exposed, the locking claw can be released.

  As described above, when the locking claw is provided on either the base end portion or the tip end portion of the fixing pin, the fixing pin is pulled out by improperly releasing the locking to the substrate box, and the substrate box is mounted on the base device. May be removed illegally.

  In view of this point, the applicant provides a locking claw on each of the distal end side portion and the proximal end side portion of the fixing pin, and locks the distal end side locking claw to the pedestal device. An application has been filed for an invention of a fixing pin having a configuration for locking to a substrate box (Japanese Patent Application No. 2007-44950).

  According to the invention of the fixing pin that has been filed, since the locking claw is provided on the distal end side portion and the proximal end side portion of the fixing pin, the locking to the base device by the distal end side locking claw is released. However, the locking to the board box by the base end side locking claws is maintained, and the fixing pin is prevented from being pulled out.

  In general, the substrate box and the pedestal device are provided with a plurality of locked portions in advance so that the fixation and release of the substrate box and the pedestal device can be repeatedly performed a plurality of times. . There are a method of preparing only one fixing pin and using it many times, and a method of preparing a plurality of fixing pins in advance and sequentially using them, and then disposing them after use.

JP 2005-111027 A Japanese Patent Application No. 2007-044950

  In the case of the above-described fixing pin, the base-end side locking claw of the fixing pin is covered and hidden from the outside by the pedestal device when locked to the board box, and is external to the base-side locking claw. It is not possible to perform a release operation to release the lock by touching directly from the side. Therefore, unless at least one of the locked portion of the board box, the locked portion of the pedestal device, and the fixing pin is broken, the fixing of the board box to the pedestal device cannot be released, and high security is achieved. .

  However, in the case of using a single fixing pin, if the fixing pin is destroyed, there is a problem that the fixing pin cannot be reused. Moreover, there is a possibility that even the fixed pin may be broken when the locked portion is broken, and it is complicated to take out the fixed pin without breaking it.

  In the case of a method in which a plurality of fixing pins are prepared in advance and are used in sequence, for example, after the fixing pins are broken and the fixing is released, the unused fixing pins are reattached to the same engagement. There is a possibility that an illegal act of disguising to be disguised if the board box and the pedestal device are not yet fixed by being locked to the stopper.

  Furthermore, in the case of the method of disposing the fixing pin, when the fixing of the substrate box and the pedestal device is released, the locked portion of the substrate box and the locked portion of the pedestal device are in a state where the fixing pin is locked. Separated from the substrate box and the pedestal device. Then, the fixing pin and the locked portion are removed in a state where the fixing pin is locked to the locked portion, and discarded as waste material.

  Therefore, when the material of the locked part and the fixing pin are different, for example, the board box is made of plastic and the fixing pin is made of metal, and when it is separated and discarded or recycled as resource waste, It is necessary to remove the stopper and separate it. Such separation work is complicated and results in high costs. Therefore, there is a problem that it is difficult to separate and dispose of the waste material or to recycle it as resource waste.

  These problems are not limited to the relationship between the board box and the pedestal device. For example, the relation between the front case body and the back case body constituting the board box, and the two members are relatively slid and coupled to each other. The case exists as well.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine having a fixing means that can suitably fix the first member and the second member while suppressing fraud. .

The movement of the fixing member with respect to the direction in the removal direction can be restricted. And the base end side latching claw latched by the 2nd member to be inserted can be covered from the outside by the 1st member to be inserted.

  Accordingly, it is possible to prevent the fixing member from being detached from the second inserted member by releasing the locking of the proximal end side locking claws, and the state where the first member and the second member are fixed to each other can be maintained. .

  On the other hand, when releasing the fixation of the first member and the second member, the second inserted member is separated from the second member, and the fixing member is removed from the first inserted member. Accordingly, the fixing member is taken out from the first member and the second member in a state where the proximal end side locking claws are locked to the second inserted member. Therefore, fixation of the 1st member and the 2nd member is cancelled | released, and the 1st member and the 2nd member can be slid relatively and can be separated.

  And in order to remove a 2nd to-be-inserted member from a fixing member, latch release operation is performed with respect to a base end side latching claw. Since the fixing member is removed from the first inserted member and the proximal end side locking claws are exposed to the outside, the locking release operation with respect to the proximal end side locking claws can be easily performed. Accordingly, it is possible to release the locking to the second inserted member, remove the fixing member from the second insertion hole, and remove the fixing member from the second inserted member.

  As described above, before the second inserted member is separated from the second member, the proximal insertion side claw is covered with the first inserted member from the outside to prevent the unlocking operation with respect to the proximal side engagement claw. be able to. Then, the second inserted member is separated from the second member, and fixed when the distal insertion side claw is released from the first inserted member and the first inserted member is removed from the fixing member. The member can be removed from the first member and the second member, the first member and the second member can be released, and the first member and the second member can be relatively slid and separated. Can be in a state.

  Then, by removing the fixing member from the first member and the second member, the proximal end side locking claw is exposed, so that the locking release operation for the proximal side locking claw can be performed and the fixing member is destroyed. It can be easily removed from the second inserted member in a reusable state without doing.

  Further, since the fixing member can be easily removed from the second inserted member, the fixing member and the second inserted member are made of a material that must be separated and discarded, such as plastic and metal. Can be disposed of easily and reliably.

Is accommodated in the empty space formed by the above-described configuration, so that interference with the bottom plate portion 211 of the fixed base portion 202 is avoided. The detailed configuration of the first inserted member 310 will be described together with the description of the configuration of the fixing means 300.

  In the movable base 203 having the above-described configuration, the rotation shaft portion 265 of the movable base portion 203 and the shaft support plate portions 243 and 244 of the fixed base portion 202 are aligned, and the shaft hole 282a of the boss plate portion 282 and the shaft support are supported. A support pin 207 is inserted into the shaft holes 243a and 244a of the plate portions 243 and 244 and the shaft hole 265a of the rotation shaft portion 265 and is rotatably supported by the fixed base portion 202.

  Specifically, for the right end portion side of the movable base portion 203, for example, as shown in FIG. 17, a shaft support plate 244 is inserted between the side end surface of the rotation shaft portion 265 and the boss plate portion 282, and the rotating base portion 203 is rotated. The shaft hole 265a of the moving shaft portion 265 and the shaft hole 244a of the shaft support plate portion 244 are aligned, and the support pin 207 is moved from the shaft hole 282a of the boss plate portion 282 through the shaft hole 244a of the shaft support plate 244 to the rotating shaft portion 265. By being inserted and attached to the shaft hole 265a, the fixed base portion 202 is rotatably supported.

  Similarly, the left end portion side of the movable base portion 203 is not particularly shown, but a shaft support plate portion 243 is inserted between the side end surface of the rotation shaft portion 265 and the boss plate portion 282, and the rotation shaft The shaft hole 265a of the portion 265 and the shaft hole 243a of the shaft support plate portion 243 are aligned, and the support pin 207 is moved from the shaft hole 282a of the boss plate portion 282 to the shaft hole 243a of the shaft support plate portion 243. By being inserted and attached to the shaft hole 265a, it is rotatably supported by the fixed base portion 202.

  The inner diameters of the shaft holes 243 a and 244 a of the shaft support plate portions 243 and 244 and the inner diameter of the shaft hole 273 a of the shaft support plate portion 273 of the reinforcing plate 271 are slightly larger than the outer diameter of the support pin 207. The inner diameter of the shaft hole 265a of the shaft hole 282a and the rotation shaft portion 265 is formed to be slightly smaller than the outer diameter of the support pin 207, and the support pin 207 corresponds to the shaft hole 282a of the boss plate portion 282 and the rotation shaft portion. It is press-fitted into the shaft hole 265a of the H.265.

  At this time, the head of the support pin 207 is flush with the side end surface of the boss plate portion 282, or is immersed in the shaft hole 282a, and the support pin 207 cannot be removed. The movable base 203 can be rotated but cannot be separated.

  For example, on the right end side of the movable base portion 203, the support pin 207 is supported by the side plate portion 264 and the boss plate portion 282 on both sides in the axial direction of the support pin 207 via the shaft support plate 244 therebetween. Then, on the left end side of the movable base b 203, both axial sides of the support pins 207 are supported by the side plate portion 263 and the boss plate portion 282 with the shaft support plate portion 243 therebetween. Accordingly, the support pin 207 can be firmly supported by the movable base portion 203, the support rigidity for supporting the movable base portion 203 on the fixed base portion 202 is strengthened, and the movable base portion 203 is stably attached to the fixed base portion 202.

  As shown in FIG. 15A, the movable base portion 203 that is rotatably supported by the fixed base portion 202 has a bottom plate portion along the surface side of the bottom plate portion 211 of the fixed base portion 202 by a locking claw portion 231. 211 is positioned and held in a standing posture position extending vertically. And as shown in FIG.15 (b), by releasing the latching by the latching claw part 231 and tilting it forward, the rotation shaft part 265 is tilted forward by about 60 degrees from the standing posture position. The abutting portion 269 abuts on the rotation stopper 253 of the cover plate portion 251 and is positioned and held at the tilting posture position.

  When the movable base portion 203 is tilted from the standing posture position, a force that rotates downward due to gravity acts, and the movable base portion 203 rotates to the tilting posture position, and the contact portion 269 is turned to the rotation stopper at the tilting posture position. 253 abuts. Therefore, the movable base portion 203 can always be positioned and held at the tilting posture position.

  As described above, at the left end portion and the right end portion of the rotation shaft portion 265, as shown in FIG. 17, shaft holes 265a are provided, and support pins 207 made of a metal material are respectively inserted.

  The tip end side of the support pin 207 is inserted further through the shaft hole 273a opened in the shaft support plate portion 273 of the reinforcing plate 271 inserted into the slit groove 268.

The portion side is inserted into and supported by the shaft holes 243a and 244a of the shaft support plate portions 243 and 244. Therefore, the left end portion and the right end portion of the rotation shaft portion 265 have higher rigidity than the central portion of the rotation shaft portion 265 in the axial direction.

  A contact portion 269 that contacts the rotation stopper 253 of the movable base 203 is provided at the left end portion and the right end portion of the rotation shaft portion 265. Therefore, the rotation stopper 253 can be reliably received, and the movable base portion 203 can be stably positioned and held at the tilted posture position.

  When the movable base portion 203 is rotatably supported by the fixed base portion 202, the upright plate portion 242 passes through a position below the rotation shaft portion 265 and the front end portion of the upright plate portion 265 is in front of the housing 2. It is arranged at a position protruding to the side. The cover plate portion 251 extends along the axial direction of the rotation shaft portion 265 so as to face the housing front side of the rotation shaft portion 265.

  Therefore, as shown in FIGS. 16A and 16B, the gap between the rotating shaft portion 265 and the upright plate portion 242 of the movable base portion 203 is set at any of the standing posture position and the tilting posture position. Also, the cover plate portion 251 covers and conceals it from the front side of the housing 2.

  Therefore, the rotation shaft portion 265 can be covered from the front side of the housing 2 by the cover plate portion 251, and the destruction action of the rotation shaft portion 265 using a tool or the like can be prevented.

  Further, the upper end portion 252 of the cover plate portion 251 is formed to be slightly higher than the rotation center axis of the rotation shaft portion 265. Thus, by setting the height position of the upper end portion 251 of the cover plate portion 251 to a height position equal to or higher than the rotation center axis line of the rotation shaft portion 265, the rotation shaft portion 265 and the cover plate are set. The gap with the portion 251 is minimized.

  Therefore, it is possible to prevent the tip of a tool such as a bar or a screw driver from being inserted between the rotating shaft portion 265 and the upright plate portion 242 or between the rotating shaft portion 265 and the cover plate portion 251. It is possible to prevent the destruction of the rotating shaft portion 265 such as using a tool to pry the tool.

  Furthermore, in the present embodiment, a configuration is adopted in which the fixed base portion 202 is fixed to the back plate 2c with the upper end portion of the bottom plate portion 211 in contact with the top plate 2a of the housing 2 (for example, , Refer to FIG. 18), the distance between the rotation center axis of the rotation shaft portion 265 and the top plate 2 a is narrow, and a bar-shaped tool such as a screw driver is inserted into the gap between the rotation shaft portion 265 and the cover plate portion 251 from above. The space that can be inserted cannot be secured.

  Therefore, it is difficult to separate the movable base portion 203 from the fixed base portion 202 due to the breakage of the rotating shaft portion 265 using a tool or the like, and it is possible to suppress the main substrate 103 from being taken away together with the movable base portion 203. it can.

  Further, the outer sides of the shaft support plate portions 243 and 244, that is, the outer side in the horizontal width direction of the housing 2 are covered and covered by the boss plate portion 282 (see FIG. 7). Therefore, it is possible to prevent the shaft support plate portions 243 and 244 from being broken by using a tool or the like, and the movable base portion 203 is separated from the fixed base portion 202 due to the breakage of the shaft support plate portions 243 and 244. It is possible to suppress the control device 101 from being taken away together with the movable base portion 203.

  Further, since the cover plate portion 251 can be formed by bending upward at the tip portion of the upright plate portion 242, it can be easily provided, and there is no need to retrofit any special parts. There is also an advantage that it can be implemented at low cost.

  For example, as shown in FIG. 13, the pedestal device 201 having the above-described configuration is configured so that the first mounting surface portion 214 is supported from the surface side of the fixed base portion 202 in a state where the movable base portion 203 is rotatably supported by the fixed base portion 202.

Accordingly, the fixed base portion 202 is fixed from both the front and the rear with respect to the back plate 2c.

  Thereby, even if the mounting screw from the front of the back plate 2c is removed, the fixed base portion 202 cannot be removed from the back plate 2c unless the screw from the back of the back plate 2c is also removed. Therefore, the removal of the fixed base portion 202 is made more difficult, and the main board unit 100 is prevented from being stolen.

  In particular, in a state where the substrate box 102 is held by the movable base portion 203, the window hole portions 274a and 261a of the movable base portion 203 are closed by the substrate box 102, and a screw is applied to the window hole portions 274a and 261a from the front of the movable base portion 203. The tip of the driver cannot be inserted.

  Further, since the bottom hole 225a of the third mounting surface portion 225 and the opening hole 211a of the bottom plate portion 211 are provided on the lower side of the pedestal device 201 that is in the vicinity of the rotation center axis, the movable base portion 203 is provided. In the state where is held at the tilted posture position, the movable base portion 203 tilted forward by about 60 degrees from the standing posture position becomes an obstacle, and the tip of the screw driver cannot be inserted into the opening hole 211a of the bottom plate portion 211.

  Therefore, with the main control device 101 attached to the movable base portion 203, it is not possible to remove the attachment screw inserted through the bottom hole 225a of the third attachment surface portion 225 in either the standing posture position or the tilting posture position. Can not. Therefore, the main board unit 100 can be prevented from being stolen.

  The screw hole portion 117a coincides with the position of the through hole 284a of the fixing flange 284 when the substrate box 102 is held on the movable base portion 203, and its central axis extends coaxially with the central axis of the through hole 284a. Thus, it is formed at a position communicating with the through hole 284a.

  The fixing screw 289 can be locked to the board box 102 by being inserted into the through hole 284a and the screw hole 117a communicating with each other from the front and screwed into the screw hole 117a.

  The fixing screw 289 extends along a direction perpendicular to the reciprocating direction of the substrate box 102 and perpendicular to the rotation center axis line by being inserted into the through hole 284a and the screw hole portion 117a. Movement in the direction of taking out from the base portion 203 can be prohibited, and the substrate box 102 held by the holding means can be fixed to the movable base portion 203.

  Therefore, a fixing means for fixing the substrate box 102 to the movable base portion 203 is constituted by the through hole 284a, the screw hole portion 117a, and the fixing screw 289.

  In this manner, the fixing surface 117 is provided on the lower right side of the front case body 110, and the fixing screw 289 can be screwed in from the front side of the housing. Therefore, for a right-handed worker, a screw driver or the like It is easy to turn the tool and can be fixed easily.

  Moreover, since the front door 3 is supported by the left end part of the housing | casing 2, when the front door 3 is opened, the left end part side of the housing | casing 2 which is a side which opposes the fixed surface 117, ie, a fixed surface. It moves to the opposite side to 117, and the fixed surface 117 side is largely opened. Therefore, a wide working space around the fixing surface 117 can be secured, and the fixing work and the removing work of the fixing screw 289 can be easily performed. Therefore, it is possible to easily perform the fixing operation and the fixing releasing operation for fixing the substrate box 102 of the main control device 101 to the movable base portion 203 of the base device 201.

  Further, when the through hole 284 a of the movable base portion 203 is provided in the vicinity of the rotation center axis, the screw hole portion 117 a of the substrate box 102 communicating with the through hole 284 a holds the substrate box 102 on the movable base portion 203. Therefore, when the substrate box 102 is moved in the direction approaching the rotation center axis and held by the movable base 203, the fixed surface of the substrate box 102 that faces the fixing flange 284 is disposed. The length of 117 does not need to be long along the moving direction of the substrate box 102, can be a shorter distance, and the shape of the substrate box 102 can be simplified.

  A flat portion 118 is formed at a side position of the fixed surface 117 so as to extend continuously flush with the surface side of the fixing flange 284 when the substrate box 102 is fixed to the movable base portion 203.

  The flat portion 118 is formed so as to constitute a seal sticking surface of a seal seal (not shown) together with the fixing flange 284. The seal seal is pasted from the surface side of the substrate box 102 so as to straddle the flat portion 118 and the fixing flange 284. Once peeled off, the adhesive is peeled off from the seal seal and cannot be pasted again. It leaves a trace that has been peeled off, and it can be confirmed whether or not the fixed seal of the substrate box 102 has been released.

  The back case body 120 has a bottom plate portion 121 that faces the back surface of the main board 103 attached to the front case body 110. A plurality of hook portions 122 are formed on the left end portion and the right end portion of the bottom plate portion 121 so as to stand in the substrate height direction and have tip portions formed in an L shape. The front case body 110 and the back case body 120 are combined by engagement with the elongated hole 113 of the front case body 110.

  The hook portion 122 of the back case body 120 is inserted into the long hole 113 of the front case body 110 by superimposing the front case body 110 and the back case body 120 on each other, and the back case body 120 is made relatively to the front case body 110. By moving in the direction of sliding upward (shifting direction), the long hole 113 of the front case body 110 is engaged. By engaging the hook portion 122 with the long hole 113, the front case body 110 and the back case body 120 are combined to form a hollow box-shaped substrate box 102.

  Then, by moving the front case body 110 relatively upward with respect to the back case body 120, the hooking portion 122 can be unlocked from the long hole 113 and separated from the front surface side and the back surface side. The board box 102 can be disassembled into the front case body 110 and the back case body 120, and the main board 103 accommodated in the board box 102 can be taken out.

  The front case body 110 and the back case body 120 are combined to form the board box 102, and are coupled by the coupling screws 132 and 133, so that relative vertical movement is restricted.

  A coupling screw hole 119 for screw coupling to the back case body 120 is provided on the left side of the upper end portion of the front case body 110. The coupling screw hole portion 119 has a screw hole screwed on the back side of the front case body 110, and the coupling screw 132 is inserted into a through hole formed in a corresponding portion of the back case body 120. The back case body 120 is coupled to the front case body 110 by being screwed into the coupling screw hole portion 119 of the 110, and relative vertical movement between the front case body 110 and the back case body 120 can be restricted. .

  A coupling screw hole 128 for screw coupling with the front case body 110 is provided on the right side of the upper end portion of the back case body 120. The coupling screw hole 128 is threaded on the front side of the back case body 120, and the coupling screw 133 is inserted into a through hole 110 a drilled in a corresponding portion of the front case body 110. The front case body 110 can be coupled to the back case body 120 by screwing into the coupling screw hole 128 of the body 120.

  Accordingly, the attachment of the coupling screws 132 and 133 prevents relative movement of the front case body 110 and the back case body 120, and the board box 120 is disassembled into the front case body 110 and the back case body 120. On the other hand, by removing the coupling screws 132 and 133, the front case body 110 and the back case body 120 are allowed to move relative to each other up and down, and the board box 102 is attached to the front case body 110 and the back case body 120. Can be broken down into

  A horizontally elongated rectangular hole 123 is formed in the upper part of the back case body 120, and a sealing member 143 of the disassembly sealing part 141 is provided in the rectangular hole 123. The sealing member 143 is provided at a position spaced apart from each other in the square hole portion 123. The sealing member 143 has a cylindrical body having an inner diameter into which the sealing pin 130 can be inserted, and is connected to the back case body 120 by a gate part 125 extending vertically in the square hole part 123.

  The gate portion 125 can be cut with a tool such as a nipper, and the sealing member 143 can be cut off from the back case body 120 by cutting. Each sealing member 143 is provided at a position coaxially continuous with the sealing member 142 of the front case body 110 by combining the front case body 110 and the back case body 120 with each other.

  Then, the board box 102 is sealed so as not to be disassembled into the front case body 110 and the back case body 120 by attaching the sealing pins 130 to the sealing member 142 and the sealing member 143 that are coaxially continuous from the front case body 110 side. The disassembly sealing part 141 is comprised.

  The sealing pin 130 is locked by inserting the proximal end portion of the sealing pin 130 into the sealing member 142 of the front case body 110 and locking the distal end portion of the sealing pin 130 within the sealing member 143 of the back case body 120. Inserted and locked. In this locked state, relative vertical movement between the front case body 110 and the back case body 120 is prohibited, and the board box 102 is illegally disassembled into the front case body 110 and the back case body 120. Can be prevented. The sealing pin 130 has a configuration that cannot be removed and reused after mounting.

  Then, the gate portion 116 of the front case body 110 and the gate portion 125 of the back case body 120 are cut with a tool such as a nipper, the sealing member 142 is cut off from the front case body 110, and the sealing member 143 is removed from the back case body 120. By excising, the sealing by the disassembly sealing part 141 can be cancelled | released.

  In the present embodiment, the gate part 116 and the gate part 125 are cut in this order, and both the sealing members 142 and 143 are cut off to release the sealing of the disassembly sealing part 141. However, the present invention is limited to this. Instead, the sealing by the disassembly sealing portion 141 can be released by cutting only one of the sealing members 142 and 143.

  By releasing the sealing by the disassembling seal part 141, relative vertical movement of the front case body 110 and the back case body 120 is allowed, and the board box 102 is disassembled into the front case body 110 and the back case body 120. It becomes possible.

  As described above, in order to disassemble the board box 102 into the front case body 110 and the back case body 120 after sealing by the disassembly sealing part 141, the sealing members 142 and 143 must be cut off to release the sealing. .

  When the sealing members 142 and 143 are removed, the substrate box 102 clearly retains a trace of the sealing members 142 and 143 being removed. In other words, the substrate box 102 cannot be disassembled into the front case body 110 and the back case body 120 as long as the trace of the excision of the sealing members 142 and 143 is not left in the substrate box 102.

  Therefore, the fact that the substrate box 102 is disassembled and the number of times can be easily grasped by observing the evidence of the excision of the sealing members 142 and 143.

  The sealing history recording sheet stuck on the sticking frame 111a is set so that the date and time of sealing and the name of the person who sealed the sticker are written on the disassembly sealing part 141. Therefore, it is possible to easily determine whether or not the substrate box 102 has been illegally disassembled by comparing the content described on the sheet with the evidence of excision of the sealing members 142 and 143. In the present embodiment, in the disassembly / sealing portion 141, the order of which of a plurality of sealing portions is used is determined in advance. For example, the left side sealing is performed first.

  Further, a second inserted member 330 of the fixing means 300 is provided in the square hole portion 123. A plurality of second inserted members 330 are provided so as to be arranged in a line on the left and right within the square hole portion 123. Each second inserted member 330 is provided at a position that is concentrically continuous with the first inserted member 310 of the movable base 203 in a state where the substrate box 120 is attached to the movable base 203.

  Then, by inserting the fixing pin 301 into the second inserted member 330 and the first inserted member 310 that are coaxially continuous from the substrate box 102 side, the substrate box 102 cannot be removed from the movable base 203. A fixing means 300 for fixing is configured.

  In the fixed pin 301, the proximal end side portion of the fixed pin 301 is inserted into and locked with the second inserted member 330, and the distal end side portion of the fixed pin 301 is inserted into the first inserted member 310 of the movable base portion 203. And locked. In such a locked state, sliding movement of the substrate box 102 in the removing direction with respect to the movable base portion 203 is prohibited, and the substrate box 102 can be prevented from being illegally removed from the movable base portion 203.

  On the other hand, in order to properly remove the substrate box 102 from the movable base portion 203, it is necessary to release the fixation by the fixing means 300. Release of fixation by the fixing means 300 can be performed by separating the second inserted member 330 from the substrate box 102 and separating the first inserted member 310 from the movable base portion 203.

  By releasing the fixation by the fixing means 300, the substrate box 102 is allowed to slide in the removing direction with respect to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203.

  As described above, in order to remove the substrate box 102 from the movable base portion 203 after being fixed by the fixing means 300, it is necessary to cut the second inserted member 330 from the substrate box 102.

  When the second member to be inserted 330 is cut off, a trace of the cut of the second member to be inserted 330 is clearly left in the substrate box 102. In other words, the substrate box 102 cannot be removed from the movable base 203 unless a trace of excision is left in the substrate box 102.

  Therefore, by observing the evidence of excision of the second inserted member 330, it is possible to easily grasp the fact of the removal of the substrate box 102 from the movable base portion 203 and the number of times.

  The seal history recording sheet pasted on the pasting frame 111a is set so that the date and time fixed by the fixing means 300, the name of the person who fixed the tag, and the like are described as history information. Therefore, it is possible to easily determine whether or not the substrate box 102 has been illegally removed by comparing the description on the sheet with the evidence of excision of the second inserted member 330. In the present embodiment, which one of the plurality of first inserted members 310 and the second inserted member 330 is used is determined in advance, for example, one by one in order from the left side to the right side. .

  These disassembly sealing part 141 and fixing means 300 are used as follows. First, at the time of manufacturing the slot machine 1, when the main board 103 is accommodated in the board box 102 and the main control device 101 is assembled, the board box 102 is moved to the front case by one of the pair of disassembly and sealing parts 141. The body 110 and the back case body 120 are sealed so that they cannot be disassembled (for example, “A” shown in FIG. 6 is sealed).

  When the main control device 101 is mounted on the pedestal device 201, the substrate box 102 is fixed by one of the plurality of fixing means 300 so that it cannot be removed from the movable base portion 203 (for example, FIG. 6). “B” shown in FIG.

  When the main board 103 is removed from the board box 102 due to occurrence of a malfunction or inspection of the main control apparatus 101, when the work on the main control apparatus 101 is performed for the first time, the fixing by the fixing means 300 is first released and the main control is performed. The apparatus 101 is removed from the pedestal apparatus 201, and then the seal by the disassembling / sealing unit 141 is released, and the main board 103 is removed from the board box 102 (for example, the sealing of “A” and the fixing of “B” shown in FIG. 6 are performed). Released).

  When the repair or inspection of the main substrate 103 is completed, the main substrate 103 is accommodated in the substrate box 102 and attached to the movable base portion 203. And it fixes using the 2nd to-be-inserted member 330 different from the 2nd to-be-inserted member 330 excised by removal work (for example, "C" shown in Drawing 6 is fixed).

  By this fixing means 300, the substrate box 102 is fixed to the movable base portion 203. In such a fixed state, the substrate box 102 cannot be pulled out and removed from the movable base portion 203. The case body 120 cannot be disassembled. Therefore, as a result, the assembled state of the front case body 110 and the back case body 120 is maintained, and the main board 103 is accommodated in the board box 102 in a sealed state.

  Then, when the work on the main controller 101 is performed for the second time or later, such as when the main board 103 is next removed from the board box 102, the fixing by the fixing means 300 is released, and the board box 102 and the movable base portion 203 The coupling is released and the main control device 101 can be detached from the pedestal device 201.

  When the main control device 101 is detached from the pedestal device 201 and the seal by the disassembling seal 141 is released, the front case body 110 and the back case body 120 can be relatively slid up and down, and the substrate box 102 Can be disassembled into the front case body 110 and the back case body 120, and the main substrate 103 can be removed.

  When the repair or inspection of the main board 103 is completed, the main board 103 is fixed by using a second inserted member 330 different from the second inserted member 330 removed by the removal operation as described above (for example, “D” shown in FIG. 6 is fixed).

  When the second inserted members 330 of all the fixing means 300 (for example, “B”, “C”, “D”, “E” shown in FIG. 6) are cut off by repeating the above fixing and releasing, The other disassembly seal 141 (for example, “F” shown in FIG. 6) of the pair of disassembly seals 141 is sealed and shipped to the manufacturer of the slot machine 1 or the like. The manufacturer or the like of the slot machine 1 unseals the disassembly / sealing part 141 to disassemble the substrate box 102 into the front case body 110 and the back case body 120, takes out the main board 103, replaces the substrate box 102, and disassembles the sealing part. One of 141 is sealed and returned to the sender.

  Next, a procedure for removing the main control device 101 from the base device 201 in a state where the main board unit 100 is attached to the back plate 2c of the housing 2 will be described below with reference to FIG.

  FIG. 18 is a diagram showing a procedure for removing the main control device 101 from the pedestal device 102. FIG. 18 (a) shows a state in which the movable base portion 203 is positioned and held in the standing posture position, and FIG. FIG. 18C shows a state in which the main control unit 101 is taken out from the movable base 203. FIG.

  In the main board unit 100, the fixed base portion 202 of the pedestal device 201 is fixed to the back plate 2c of the housing 2, and the movable base portion 203 is rotated around the rotation center axis extending in the lateral width direction of the housing 2. It is attached to the housing 2 so that it can be selectively placed in a standing posture position and a tilting posture position by being pivotally supported and pivoted.

  In the state shown in FIG. 18A, the movable base portion 203 of the pedestal device 201 is positioned and held in the standing posture position by the left and right locking claws 231 constituting the standing posture positioning holding means 205.

  In this state, the locking claw portions 231 are elastically deformed in the left-right direction to be separated from each other, the locking of the movable base portion 203 by the locking claw portions 231 is released, and the distal end side of the movable base portion 203 is placed on the housing. Rotate to pull out to the front side of 2. As a result, the movable base portion 203 is tilted to the front side of the housing 2 with the support pin 207 as the rotation center, and the contact portion 269 is a rotation stopper of the cover plate portion 251 as shown in FIG. Positioned and held at a tilted posture position that is in contact with H.253 and tilted by a rotation angle of about 60 degrees from the standing posture position.

  Then, the locking piece 286 of the locking portion 285 is elastically deformed to release the engagement of the protrusion 121a into the locking hole 287, and the locking of the substrate box 102 to the movable base portion 203 is released. As shown in FIG. 18 (c), the main controller 101 is separated from the mounting portion 262, which is a sliding contact direction set in advance along the bottom plate portion 211 of the movable base portion 203, in other words, the rotation shaft portion. It is slid in a direction perpendicular to the rotation center axis line of H.265, and is pulled out from the movable base 203 and removed. The main control device 101 can be attached to the pedestal device 201 by performing the above removal procedure in reverse.

  The above-described pedestal device 201 can position and hold the movable base portion 203 positioned and held in the standing posture position in the tilting posture position by rotating the movable base portion 203 in the tilting direction toward the front side of the housing 2.

  That is, when the movable base portion 203 is tilted from the standing posture position to the front side of the housing 2, a force that rotates downward due to gravity is applied, and the movable base portion 203 is rotated to the tilting posture position. As a result, the contact portion 269 contacts the rotation stopper 253. Therefore, the movable base 203 can always be positioned and held at a preset tilt posture position.

  Therefore, when the work for removing the substrate box 102 from the movable base portion 203 or the operation for attaching it to the movable base portion 203 is performed, it is not necessary to support and position and fix the movable base portion 203 with the other hand. Therefore, it is possible to easily attach and remove the substrate box 102 to and from the movable base portion 203, and in the attachment operation, it is easy to attach the substrate box 102 to the movable base portion 203. Therefore, it is possible to shorten these work times.

  Since the movable base portion 203 can be selectively disposed in the standing posture position and the tilting posture position, the main substrate 103 passes through the front case portion 110 of the substrate box 102 from the front side of the housing 2 in the standing posture position. The surface of the main board 103 can be seen through the bottom plate part 211 of the movable base part 203 and the back case part 120 of the board box 102 from the front side and from the upper side in the tilted posture position. .

  Therefore, both the front surface and the back surface of the main substrate 103 can be visually recognized from the front side of the housing 2, and it is not necessary to look into the housing 2 from the lateral direction when viewing the back surface of the main substrate 103. 2 and visible from above.

  In particular, in the present embodiment, since the front door 3 is provided in the housing 2 so as to rotate in the lateral opening direction so as to close the front side of the housing 2, It is visible from the front side of the housing 2 without an obstacle. Therefore, the back surface of the main substrate 103 can be visually recognized without being obstructed by the front door 3, and the visual recognition work on both the front surface and the back surface of the main substrate 103 can be easily performed. Therefore, it is possible to easily confirm whether or not the main board 103 has been modified for the purpose of obtaining an illegal profit.

  19 is a plan view of the pedestal device 201, and FIG. 20 is a cross-sectional view taken along the line iv-iv in FIG. A flange 126 is provided on the back case body 120 of the substrate box 102.

  The flange 126 is provided above the second inserted member 330 and protrudes rearward from the back case body 120 (see FIG. 22). In a state in which the substrate box 102 is attached to the movable base portion 203, the substrate box 102 is located above the bottom plate portion 261 of the movable base portion 203 and protrudes to a position behind the bottom plate portion 261.

  Therefore, by attaching the substrate box 102 to the movable base portion 203, the substrate box 102 is positioned above the portion extending from the first inserted member 310 to the second inserted member 330, and the alignment between the back case body 120 and the bottom plate portion 261 is performed. The eye portion can be covered from above the substrate box 102. Accordingly, unauthorized operations such as cutting the fixing pin 301 by inserting a cutter or a saw blade between the back case body 120 and the bottom plate portion 261 can be prevented.

  Further, a locking hole 127 is formed in the flange 126, and a locking part 288 that engages with the locking hole 127 is protruded from the movable base part 203. The locking hole 127 is formed through the flange 126 vertically. In the present embodiment, a total of four are provided, and are arranged in the vicinity of each second inserted member 330.

  The locking portion 288 protrudes upward from the bottom plate portion 261 of the movable base portion 203. Then, with the substrate box 102 attached to the movable base 203, the shape enters the locking hole 127 from below the flange 126, penetrates through the locking hole 127, and the tip protrudes above the flange 126. Have.

  Therefore, by attaching the board box 102 to the movable base portion 203, the locking portion 288 enters the locking hole 127 from below the flange 126, penetrates through the locking hole 127, and protrudes above the flange 126. Can be made.

  Therefore, even when the bottom plate portion 261 is biased toward the rear side with respect to the back case body 120, the locking portion 288 can be locked in the locking hole 127, and the bottom plate portion It is possible to prevent a gap from being generated between 261 and the back case body 120.

  Therefore, the effect of preventing an unauthorized operation such as cutting the fixing pin 301 by inserting a cutter or a saw blade between the back case body 120 and the bottom plate portion 261, which is an effect of the flange 126, is further improved. be able to.

  The distal end side in the axial direction of each base end side locking claw 305 is formed to have the same size as the outer diameter of the thin shaft portion 302b. Then, both ends in the width direction of the base end side locking claws 305 are chamfered in parallel so as to have a width substantially the same as the width of the thick shaft portion 302a.

  The stepped surface 305a faces the rear end surface 330a of the second inserted member 330 when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 333 and protruded from the second inserted member 330. It is formed to be able to. The tapered surface 305b abuts against the inner peripheral surface of the second insertion hole 333 when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330, and the slit 306 is formed. It forms so that the axial part 302 may be urged | biased in the direction which mutually approaches via it. The thick shaft portion 302a is elastically deformed by urging the slits 306 toward each other through the slit 306 to move the base end side locking claws 305 in the directions approaching each other, and the urging force disappears. Thus, it can be restored and returned to the original position.

  The distal end side locking claws 304 are provided at the distal end portion of the thin shaft portion 302b, and are spaced apart from the thin shaft portion 302b with the slit 306 therebetween and in the same direction as the proximal end side locking claws 305. It is paired so that it protrudes toward. Each distal end side claw 304 has a stepped surface 304a formed in a stepped shape so as to be substantially perpendicular to the shaft portion 302, and a stepped surface 304a as it moves from the axially proximal end side to the distal end side. It has a tapered inclined surface 304b that gradually decreases in diameter from the outer peripheral edge.

  The front end side in the axial direction of each front end side claw 304 is formed to have a smaller diameter than the outer diameter of the thin shaft portion 302b. Then, both ends in the width direction of the distal end side claw 304 are chamfered in parallel so as to have a width substantially the same as the width of the thin shaft portion 302b.

  The stepped surface 304a faces the rear end surface 310a of the first inserted member 310 when the thin shaft portion 302b of the fixing pin 301 is inserted into the first insertion hole 313 and protrudes from the first inserted member 310. It is formed to be able to. The inclined surface 304b is in contact with the inner peripheral surface of the first insertion hole 313 when the thin shaft portion 302b of the fixing pin 301 is inserted into the first insertion hole 313 of the first inserted member 310. The shaft portions 302b are formed so as to be urged toward each other. The thin shaft portion 302b is elastically deformed by urging it in a direction approaching each other through the slit 306, moving the distal end side locking claws 304 in a direction approaching each other, and restored by disappearance of the urging force. And it is constituted so that it can return to the original position.

  The front-end side locking claws 304 are configured to move in directions approaching each other by being biased in directions approaching each other, and can be restored and returned to their original positions by disappearance of the biasing force. .

  Even if the proximal-side latching claws 305 are picked from the outside and urged in the direction of approaching each other, the proximal-side latching claws 305 are engaged with the second inserted member 330. When the base end side locking claws 304 are picked from the outside in the radial direction and are urged toward each other, the base end side locking claws with respect to the second inserted member 330 can be maintained. Elastic strength is set so that the lock of 305 can be released.

  On the other hand, the front end side locking claw 304 is formed so as to be positioned radially inward from the outer peripheral surface of the thick shaft portion 302a. In other words, the distal-side locking claw 304 is set such that the radial distance from the axial center of the thin shaft portion 302b to the maximum protruding portion of the distal-side locking claw 304 is equal to or smaller than the radius of the thick shaft portion 302a. The thick shaft portion 302a is formed so as not to protrude radially outward from the outer peripheral surface of the thick shaft portion 302a.

  In the present embodiment, the maximum distance between the pair of distal end side locking claws 304, that is, the distance between the pair of distal end side locking claws 304 in the radial direction of the shaft portion 302 and farthest from each other. The separation distance (distance between the maximum protruding portions in the radial direction) is not larger than the diameter of the thick shaft portion 302a.

  Therefore, when the thin shaft portion 302 b of the fixing pin 301 is moved in a direction to be removed from the second insertion hole 333 of the second inserted member 330, the distal end side locking claw 304 is caught by the second inserted member 330. The distal end portion can be removed from the second insertion hole 333 without passing through the second insertion hole 333, and can be easily removed when removing the regulating (fixing) member from the second inserted member. Can do.

  The first inserted member 310 is made of a synthetic resin material such as polycarbonate having a predetermined rigidity like the fixing pin 301, and is a perspective view of FIG. 22A and a front view of FIG. As shown in b), it has a flat plate portion 312. The flat plate portion 312 has a horizontally long rectangular shape and a flat plate block shape that is thicker than the bottom plate portion 261 of the movable base portion 203. A first insertion hole 313 is formed at a substantially central position of the flat plate portion 312.

  The first insertion hole 313 has a round hole shape having a constant diameter and extending in the axial direction, and the rear end is opened on the rear end surface 310 a of the first inserted member 310 that is the back surface of the flat plate portion 312. doing. The inner diameter is slightly larger than the outer diameter of the thin shaft portion 302b and smaller than the maximum separation distance of the pair of distal end side locking claws 304 so that the thin shaft portion 302b of the fixing pin 301 is inserted. When the thin shaft portion 302b of the pin 301 is inserted, an inner diameter that forms a slight gap with the outer peripheral surface of the thin shaft portion 302b, and an axial length that is substantially the same as or slightly shorter than the axial length of the thin shaft portion 302b have.

  A housing portion 314 (first housing portion) is formed in the axially front portion of the first insertion hole 313. The accommodating portion 314 is formed with a diameter increased between the first insertion hole 313 and a step, and opens to the front end surface 310 b of the first inserted member 310 that is the surface of the flat plate portion 312.

  For example, as shown in FIG. 25, the accommodating portion 314 is formed when the thin shaft portion 302 b of the fixing pin 301 is inserted into the first insertion hole 313 and the distal end side locking claw 304 is locked to the first inserted member 310. The inner diameter of the pair of base end side locking claws 305 is the same as or slightly larger than the maximum distance between the base end side locking claws 305 and the axial length of the base side locking claws 305 is the same. Alternatively, it has a slightly larger axial length.

  Therefore, when the thin shaft portion 302b of the fixing pin 301 is inserted into the first insertion hole 313 and the distal end side locking claw 304 is protruded rearward from the rear end surface 310a of the first inserted member 310, the distal end side The flat plate portion 312 can be disposed on the side of the locking claw 304 with respect to the direction in which the fixing pin 301 is removed, and the step surface 304a of the front end side locking claw 304 can be opposed to the rear end surface 310a of the first inserted member 310. . When the fixing pin 301 is to be moved in the removal direction from such a state, the stepped surface 304 a of the front end side locking claw 304 is brought into contact with the rear end surface 310 a of the first inserted member 310 to fix the fixing pin 301. It is possible to restrict the movement in the pulling-out direction and to lock the fixing pin 301.

  Further, when the fixing pin 301 is removed from the first inserted member 310, the pair of distal end side locking claws 304 protruding in the axial direction from the rear end surface 310a of the first inserted member 310 are brought closer to each other. And is elastically deformed to narrow the pair of leading end side locking claws 304 to a position where the maximum separation distance is smaller than the inner diameter of the first insertion hole 313. Then, the opposing of the front end side locking claw 304 to the rear end surface 310 a of the first inserted member 310 is released to release the locking by the front end side locking claw 304, and the fixing pin 301 is fixed to the first inserted member 310. Can be moved in the axial direction and in the relatively withdrawing direction, and the distal end side claw 304 can be passed through the first insertion hole 313.

  Holding claws 315 for detachably holding the first inserted member 310 to the fitting portion 321 of the movable base portion 203 are provided at both left and right positions of the flat plate portion 312. The two holding claws 315 have an arm portion 315a that extends substantially perpendicularly from the rear surface of the flat plate portion 312 and a claw portion 315b that protrudes in a direction away from each other at the tip of the arm portion 315a.

  The arm portion 315a has an elastic force capable of moving toward the center in the left-right direction, which is a direction in which the claw portions 315b approach each other by elastic deformation, and returning the claw portion 315b to the original position by restoration.

  The claw portion 315b has an outer surface that is inclined so as to gradually move outward in the left-right direction, which is a direction away from each other as it moves toward the proximal end side of the arm portion 315a. When inserted into the claw hole portion 321c of the fitting portion 321, the arm portion 315a can be elastically deformed by coming into contact with the claw hole portion 321c. And it has the level | step difference surface formed in the step shape so that it may become a substantially perpendicular | vertical surface with respect to the arm part 315a, and it can project and hook from the opening hole 321d of the fitting part 321. .

  The first inserted member 310 having the above configuration is detachably attached to the fitting portion 321 provided in the movable base portion 203. The fitting portions 321 are integrally formed with the bottom plate portion 261 of the movable base portion 203, and in the present embodiment, a total of four pieces are arranged in a line on the left and right in the upper center of the bottom plate portion 261. (See FIGS. 10 and 12).

  The fitting portion 321 is recessed from the surface of the bottom plate portion 261 toward the back surface side, and when the first inserted member 310 is attached, the surface of the flat plate portion 312 is the bottom plate portion 261 of the movable base portion 203. It has the structure hold | maintained so that it may not protrude from the surface. In this way, the substrate box 102 is slid relative to the movable base 203 by configuring the flat plate 312 of the first inserted member 310 so that the surface of the flat plate 312 does not protrude from the surface of the bottom plate 261 of the movable base 203. It is possible to prevent the board box 102 from being caught by the first inserted member 310 when it is made.

  As shown in FIG. 23, the fitting portion 321 includes a rectangular recess portion 321a in which the flat plate portion 312 is fitted and accommodated, a round hole portion 321b provided at a substantially central position of the rectangular recess portion 321a, and a rectangular recess portion 321a. And a claw hole portion 321c that is drilled along the left and right sides of the round hole portion 321b and into which the holding claw 315 is inserted.

  The rectangular recess 321a has a depth dimension substantially the same as the plate thickness of the flat plate portion 312. The round hole portion 321b has a distal end side locking claw 304 in a state where the board box and the base device are fixed to each other by the fixing pin 301. (See, for example, FIG. 25). The claw hole portion 321c extends along the axial direction of the round hole portion 321b, has a slightly shorter length than the arm portion 315a of the holding claw 315, and has an opening hole 321d formed at the bottom thereof. .

  In the opening hole 321d, the holding claw 315 is inserted into the claw hole portion 321c, the flat plate portion 312 is fitted into the rectangular concave portion 321a, and the surface of the flat plate portion 312 is flush with the surface of the bottom plate portion 261 of the movable base portion 203. In this state, the claw portion 315b of the holding claw 315 is formed at a position protruding from the opening hole 321d. Furthermore, the maximum separation distance of the pair of claw hole portions 321c is formed to be the same as or slightly shorter than the maximum separation distance of the pair of arm portions 315a of the first inserted member 310.

  Then, the arm part 315a of the holding claw 315 is elastically deformed and inserted into the claw hole part 321c, and the claw part 315b is projected from the opening hole 321d, whereby the arm part 315a can be restored and the claw part 315b can be hooked. The first inserted member 310 can be held in a state of being attached to the fitting portion 321.

  Further, when removing the first inserted member 310 from the fitting portion 321, the pair of claws 315b protruding from the opening hole 321d is urged in a direction approaching each other to elastically deform each arm portion 315a, By removing the catch of the claw portion 315b, the holding of the first inserted member 310 can be released, and the first inserted member 310 can be detached from the fitting portion 321. The removal operation of the first inserted member 310 can be performed from the back of the bottom plate portion 261 in a state where the movable base portion 203 is positioned and held in the tilted posture position.

  As shown in FIGS. 23 and 25, the rectangular concave portion 321 a and the round hole portion 321 b are closed on the rear side, and from the rear side of the bottom plate portion 261, the flat plate portion 312 of the first inserted member 310 and the distal end side of the fixing pin 301. It has a structure in which the locking claw cannot be touched. The rectangular recess 321a, the round hole 321b, and the claw hole 321c of the fitting portion 321 are all recessed or drilled along a direction orthogonal to the bottom plate 261. It can be formed by a mold sandwiched from the front side and the back side, and the movable base 203 can be easily manufactured.

  On the other hand, the second inserted member 330 is provided integrally with the back case body 120 (second member) of the board box 102 as shown in FIG. 24, for example. When the substrate box 102 is mounted on the movable base portion 203, the substrate box 102 is provided so as to face each first inserted member 310 of the movable base portion 203 in the direction perpendicular to the sliding movement direction of the substrate box 102. It has been.

  As shown in FIG. 24, the second inserted member 330 has a cylindrical shape with a certain thickness, and a second insertion hole 333 is formed at the center thereof. The second inserted member 330 is supported by the gate portion 331 in the square hole portion 123 of the back case body 120.

  The gate portion 331 is provided so as to span the square hole portion 123 in the vertical direction, and supports the second inserted member 330 at a substantially central position in the height direction inside the square hole portion 123. Then, the second inserted member 330 can be separated from the back case body 120 by cutting the portion positioned above and below the second inserted member 330 with a tool such as a nipper. It is configured.

  The gate portion 331 extends along the direction in which the center axis of the second inserted member 330 is orthogonal to the bottom plate portion 121 of the back case body 120, and the rear end surface 330 a of the second inserted member 330 is the rear surface of the bottom plate portion 121. The second inserted member 330 is supported so as to be flush with the other.

  The gate portion 331 has a certain thickness and a certain width at both the left and right positions of the second inserted member 330 and extends up and down. The rear end edge in the width direction of the gate portion 331 is the second inserted member 330. A rear end edge in the width direction of the gate portion 331 and the movable base portion 203 in a state where the substrate box 102 is held by the movable base portion 203 and located at a position on the front side (front case body 110 side) with respect to the rear end surface 330a. It is provided so as to be separated from the bottom plate portion 261 with a predetermined interval.

  In this way, by providing a predetermined gap between the widthwise rear edge of the gate portion 331 and the bottom plate portion 261 of the movable base portion 203, for example, a tool is inserted from the front case body 110 side to cut the gate portion 331. When this is done, the tool can be reliably brought into contact with the entire width of the gate portion 331, and the gate portion 331 can be easily cut.

  In the present embodiment, the gate portion 331 has a lateral width that is approximately half the axial length of the second inserted member 330, and the front end edge in the width direction of the gate portion 331 is the second inserted member 330. It is formed so that it is flush with the front end surface, and the rear end edge in the width direction of the gate portion 331 is positioned at a substantially central position in the axial direction of the second inserted member 330.

  The second inserted member 330 has an axial length substantially the same as the length from the proximal end of the fixing pin 301 to the distal end of the thick shaft portion 302 a, and the second insertion hole 333 is the second inserted member 330. It is formed so as to penetrate the inside on the same axis. The second insertion hole 333 is slightly larger than the outer diameter of the thick shaft portion 302a so that a slight gap can be formed between the outer surface of the thick shaft portion 302a when the thick shaft portion 302a of the fixing pin 301 is inserted. And it has an internal diameter smaller than the largest separation distance of a pair of base end side latching claw 305. FIG. Then, the base end side locking claw 305 protrudes from the second insertion hole 333 and the stepped surface 305a of the base end side locking claw 305 is opposed to the rear end surface 330a of the second inserted member 330. The axial length is substantially the same as or slightly shorter than the axial length.

  A diameter-enlarged portion 334 is formed in the front portion of the second insertion hole 333 in the axial direction. The diameter-enlarged portion 334 is formed to have a diameter increased between the second insertion hole 333 through a step surface 334 a and opens to the front end surface 330 a of the second inserted member 330.

  The enlarged diameter portion 334 accommodates the flange portion 303 when the thick shaft portion 302 a of the fixing pin 301 is inserted into the second insertion hole 333 and the proximal end side locking claw 305 is locked to the second inserted member 330. The inner diameter is slightly larger than the outer diameter of the collar portion 303 and the axial length is the same as or slightly longer than the axial length of the collar portion 303.

  Therefore, when the thick shaft portion 302 a of the fixing pin 301 is inserted into the second insertion hole 333, the proximal end side locking claw 305 can be protruded from the rear end surface 330 a of the second inserted member 330, and the proximal end side The rear end surface 330a of the second inserted member 330 can be arranged to face the locking claw 305 on the side in which the fixing pin 301 is removed. Then, when the fixing pin 301 is urged in the removal direction from such a state, the stepped surface 305a of the proximal end side locking claw 305 is brought into contact with the rear end surface 330a of the second inserted member 330 to fix the fixing pin 301. It is possible to restrict the movement in the pulling-out direction and to lock the fixing pin 301. Moreover, the collar part 303 is accommodated in the enlarged diameter part 334, and it can restrict | limit that the fixing pin 301 is moved to the insertion direction any more, and can be positioned in a predetermined insertion position.

  When the fixing pin 301 is removed from the second inserted member 330, the pair of proximal end locking claws 305 protruding from the rear end surface 330 a of the second inserted member 330 are urged toward each other. Thus, the maximum distance between the pair of proximal end side locking claws 305 is narrowed to a position smaller than the inner diameter of the second insertion hole 333. Then, the opposing of the rear end surface 330 a of the second insertion hole 333 and the stepped surface 305 a of the proximal end side locking claw 305 is released, and the fixing pin 301 is moved relative to the second inserted member 330 in the axial direction. The fixing pin 301 can be removed from the second inserted member 330 by moving the proximal end side locking claw 305 through the second insertion hole 333 by moving in the removal direction.

  Since the pair of distal end side locking claws 304 has a maximum separation distance smaller than the outer diameter of the thick shaft portion 302a, the pair of distal end side locking claws 304 can pass through the second insertion hole 333 as they are, and the second insertion member 330 is thicker. After the shaft portion 302a is removed, the thin shaft portion 302b can be continuously removed. Therefore, the fixing pin 301 can be easily detached from the second inserted member 330 without destroying the fixing pin 301.

  Next, a method for using the fixing means 300 and its operation and effects will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 300, the first inserted member 310 is attached to the fitting portion 321 of the first inserted member 310, and the substrate box 102 is attached to the movable base portion 203. Move it by sliding. Then, the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 from the front of the substrate box 102.

  When the distal end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330, the inclined surface 305 b of the proximal end side locking claw 305 becomes the second insertion hole 333. The state is in contact with the inner peripheral surface. When the fixing pin 301 is further pushed from this state, the proximal end side locking claws 305 are urged in a direction approaching each other. And when elastically deforming to a position where the maximum separation distance of the pair of base end side latching claws 305 is smaller than the inner diameter of the second insertion hole 333, it passes through the second insertion hole 333, as shown in FIG. It protrudes in the axial direction from the rear end surface 330 a of the second inserted member 330.

  When the proximal end side locking claw 305 passes through the second insertion hole 333 and protrudes in the axial direction from the rear end surface 330a, the urging force by the second insertion hole 333 is released, and is restored to return to its original state. The stepped surface of the base end side locking claw 305 is disposed at a position facing the rear end surface 330 a of the second inserted member 330.

  On the other hand, when the fixing pin 301 is pushed in, the distal end side locking claw 304 is urged in the direction in which the inclined surface 304b comes into contact with the inner peripheral surface of the first insertion hole 313 of the first inserted member 310 and approaches. Is done. When the maximum distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 313, the first insertion hole 313 passes through the first insertion hole 313, as shown in FIG. The first insertion member 310 protrudes in the axial direction from the rear end surface 310a.

  When the front end side claw 304 passes through the first insertion hole 313 and protrudes in the axial direction from the rear end surface 310a of the first inserted member 310, the urging force by the first insertion hole 313 is released and restored. Then, the bending returns to the original, and the stepped surface 304 a of the front end side locking claw 304 is disposed at a position facing the rear end surface 310 a of the first inserted member 310.

  At this position, the flange portion 303 of the fixing pin 301 is inserted into the enlarged diameter portion 334 of the second inserted member 330, and the bottom surface of the flange portion 303 is substantially flush with the front end surface of the second inserted member 330. It is arranged at the position. And the collar part 303 contact | abuts to the level | step difference surface 334a of the 2nd insertion hole 333 and the enlarged diameter part 334, and the movement to the further insertion direction of the fixing pin 301 is controlled.

  Here, when the fixing pin 301 is to be moved in the removal direction opposite to the insertion direction, the stepped surface 304a of the front end side claw 304 abuts on the rear end surface 310a of the first inserted member 310. At the same time, the step surface 305a of the base end side locking claw 305 contacts the rear end surface 330a of the second inserted member 330, and the movement of the fixing pin 301 in the pulling direction is stopped.

  That is, the thin shaft portion 302 b of the fixing pin 301 is inserted and locked in the first insertion hole 313 of the first inserted member 310, and the thick shaft portion 302 a is inserted into the second insertion hole 333 of the second inserted member 330. Thus, the fixing pin 301 cannot be removed from the first inserted member 310 and the second inserted member 330.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 300 described above, first, the second inserted member 330 to which the fixing pin 301 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 330 from the back case body 120, the gate portion 331 supporting the second inserted member 330 on the back case body 120 is cut with a tool such as a nipper.

  The gate portion 331 is cut at a location located above and below the second inserted member 330. The second inserted member 330 is separated from the back case body 120 by cutting the gate portion 331. Since the gate part 331 is provided at a position spaced apart from the bottom plate part 261 of the movable base part 203 with a predetermined interval, when the tool is inserted from the front case body 110 side and the gate part 331 is cut. The tool can be reliably brought into contact with the entire width of the gate portion 331, and the gate portion 331 can be easily cut.

  Next, the first inserted member 310 is separated from the movable base 203. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, so that the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of claw portions 315b that protrude from the opening hole 321d to the back surface side of the bottom plate portion 261 and are hooked on the outer end surface of the claw hole portion 321c are operated from the back surface side of the bottom plate portion 261 so as to approach each other. Then, the hook of the claw portion 315b is removed, the first inserted member 310 is pushed out to the surface side of the bottom plate portion 261, and is removed from the fitting portion 321.

  This means that “the board box 102 is fixed to the base device 201 and the board box 102 can be slid in the sliding direction with respect to the movable base 203, and the board box 102 can be moved. It can be removed from the base part 203.

  When the used fixing pin 301 is reused, for example, when the board box 102 is fixed to the pedestal device 201 by being inserted into the other first inserted member 310 and the second inserted member 330 located adjacent to each other, it is fixed. The first inserted member 310 and the second inserted member 330 are removed from the pin 301.

  In order to remove the first inserted member 310 from the fixing pin 301, the distal end side locking claws 304 protruding from the first insertion hole 313 of the first inserted member 310 are urged in a direction approaching each other, and the distal side The opposing of the step surface 304a of the locking claw 304 and the rear end surface 310a of the first inserted member 310 is released, and the fixing pin 301 is urged as it is. As a result, the distal end side locking claws 304 can be passed through the first insertion hole 313 while being bent in a direction approaching each other, and the first inserted member 310 can be removed from the fixing pin 301.

  When the first inserted member 310 is removed from the fixing pin 301, the proximal end side locking claws 305 are exposed. Therefore, in order to remove the second inserted member 330 from the fixing pin 301, the proximal end side locking claws 305 protruding from the rear end surface 330a of the second inserted member 330 are urged in a direction approaching each other, 2 The hook to the inserted member 330 is removed, and the fixing pin 301 is urged in the direction of pulling out as it is. Thereby, the inside of the 2nd insertion hole 333 can be passed in the state which bent the base end side latching claw 305 in the direction which approaches mutually.

  Further, since the maximum separation distance between the pair of front end side locking claws 304 is smaller than the outer diameter of the thick shaft portion 302a, the second insertion hole 333 can be passed as it is. Therefore, after the thick shaft portion 302a is removed from the second inserted member 330, the thin shaft portion 302b can be continuously removed. Therefore, the fixing pin 301 can be easily removed from the second inserted member 330 without destroying it.

  According to the fixing means 300, the fixing pin 301 has the distal end side locking claw 304 covered by the fitting portion 321 in a state where the substrate box 102 and the movable base portion 203 are fixed, and the proximal end side locking is performed. The claw 305 is covered and hidden between the first inserted member 310 and the second inserted member 330.

  Therefore, for example, in a state where the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 301, the fitting portion 321 is broken to expose the distal end side claw 304, and the engagement with the first inserted member 310 is performed. Even when the stop is released, the proximal-side locking claw 305 is locked to the second inserted member 330 in a state of being covered between the first inserted member 310 and the second inserted member 330. Therefore, the locking of the proximal end side locking claw 305 cannot be released, and unauthorized fixing of the fixing pin 301 can be prevented.

  On the other hand, the second inserted member 330 is separated from the substrate box 102 and the first inserted member 310 is separated from the movable base portion 203, so that the first inserted member 310 and the second inserted member 330 are the main board unit 100. When it is taken out from the front end, the front end side claw 304 of the fixing pin 301 is exposed, and the front end side that releases the engagement with the first inserted member 310 by urging the front end side engagement claw 304 in a direction approaching each other. The locking claw release operation is possible. Therefore, the distal end side locking claw 304 can be released from the distal side locking claw 304 to release the locking to the first inserted member 310, and the first inserted member 310 can be detached from the fixing pin 301. .

  When the first inserted member 310 is removed from the fixing pin 301, the base end side locking claws 305 of the fixing pin 301 are exposed, and the base end side locking claws 305 are urged in a direction approaching each other to be second The base end side locking claw releasing operation for releasing the locking to the insertion member 330 becomes possible. Therefore, the base end side locking claw 305 is operated to release the base end side locking claw releasing operation to release the locking to the second inserted member 330 and the second inserted member 330 is removed from the fixing pin 301. Can do. Accordingly, the fixing pin 301 can be detached from the first inserted member 310 and the second inserted member 330 in a reusable state without damaging or damaging the fixing pin 301.

  That is, according to the fixing means 300, when the first inserted member 310 is removed from the fixing pin 301, the proximal end side locking claws 305 can be exposed. The locking to the inserted member 330 can be easily released.

  Therefore, the base end side portion of the fixing pin 301 can be pulled out from the second insertion hole 333 of the second inserted member 330, the second inserted member 330 can be easily removed from the fixing pin 301, and the fixing pin 301 can be removed. There is no risk of destroying.

  Further, since the fixing pin 301 can be taken out in a reusable state, only one fixing pin 301 needs to be prepared for one slot machine 1, and a spare fixing pin 301 is added. There is no need. Therefore, for example, after breaking the fixed pin 301 and releasing the connection between the movable base portion 203 and the substrate box 102, the unused fixed pin 301 is replaced with the same first inserted member 310 and second inserted member 330 again. It is possible to prevent a fraudulent act of disguising if the movable base portion 203 and the substrate box 102 are not yet released from the insertion.

  In addition, for example, one of the movable base 203 or the substrate box 102 and the fixed pin 301 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.

(Second Embodiment)
FIG. 26 is a diagram schematically showing the configuration of the fixing means 400 in the second embodiment. The same components as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the above-described first embodiment, the first inserted member 310 is detachably attached to the fitting portion 321 of the movable base portion 203. However, in the present embodiment, the first inserted member 401 is attached to the movable base. It has a structure formed integrally with the bottom plate part 261 of the part 203.

  The fixing means 400 in the present embodiment includes a fixing pin 301, a first inserted member 401, and a second inserted member 330. The first inserted members 401 are integrally formed with the bottom plate portion 261 of the movable base portion 203, and in the present embodiment, a total of four members are arranged in a line on the left and right in the upper center of the bottom plate portion 261. ing.

  The first inserted member 401 has a convex portion 402 that protrudes rearward from the back surface of the bottom plate portion 261. The convex portion 402 has a cylindrical shape having a constant diameter and extending in the axial direction. A first insertion hole 403 is formed along the axial direction at a substantially central position of the convex portion 402.

  The first insertion hole 403 has a round hole shape having a constant diameter and extending in the axial direction, and the rear end is open on the rear end surface 402 a of the convex portion 402. The first insertion hole 403 is slightly larger than the outer diameter of the thin shaft portion 302b so as to form a slight gap with the outer peripheral surface of the thin shaft portion 302b when the thin shaft portion 302b of the fixing pin 301 is inserted. And it has an inner diameter smaller than the maximum separation distance of a pair of front end side latching claws 304. Then, the axial length of the thin shaft portion 302b is substantially the same so that the front end side locking claw 304 protrudes from the first insertion hole 403 and the step surface 304a of the front end side locking claw 304 faces the rear end surface of the convex portion 402. Alternatively, it has a slightly shorter axial length.

  Therefore, when the thin shaft portion 302 b of the fixing pin 301 is inserted into the first insertion hole 403, the rear end surface 402 a of the convex portion 402 is opposed to the distal end side locking claw 304 in the removal direction of the fixing pin 301. When the fixing pin 301 is biased in the removal direction, the stepped surface 304a of the front end side locking claw 304 is brought into contact with the rear end surface 402a of the convex portion 402 so that the fixing pin 301 The fixing pin 301 can be locked by restricting movement in the removal direction.

  A storage portion 404 is formed in the front portion of the first insertion hole 403 in the axial direction. The accommodating portion 404 is formed so as to be enlarged in diameter with respect to the first insertion hole 403 through a step, and is open to the front end surface 401a of the first inserted member 401 that is flush with the surface 261a of the bottom plate portion 261. doing.

  For example, as shown in FIG. 26, the accommodating portion 404 is a case where the thin shaft portion 302 b of the fixing pin 301 is inserted into the first insertion hole 403 and the distal end side locking claw 304 is locked to the first inserted member 401. So that the entire base end side latching claws 305 can be accommodated, and the inner diameter of the pair of base end side latching claws 305 is the same as or slightly wider than that of the base end side latching claws 305 and the axial length of the base end side latching claws 305 is the same. Alternatively, it has a slightly longer axial length.

  When the fixing pin 301 is removed from the first inserted member 401, the pair of front end side locking claws 304 protruding in the axial direction from the rear end surface 402a of the convex portion 402 are urged toward each other. It is elastically deformed and is narrowed to a position where the maximum separation distance between the pair of front end side locking claws 304 is smaller than the inner diameter of the first insertion hole 403. Then, the opposing of the rear end surface 402 a of the convex portion 402 and the stepped surface 304 a of the tip side locking claw 304 is released to release the locking of the tip side locking claw 304, and it is fixed to the first inserted member 401. The fixing pin 301 is removed from the first inserted member 401 by moving the pin 301 in the axial direction and in the direction in which the pin 301 is relatively removed and passing the distal end side locking claw 304 through the first insertion hole 403. can do.

  Since the first inserted member 401 is recessed along the direction orthogonal to the bottom plate portion 261, it can be formed by a mold sandwiched from the front surface side and the back surface side of the bottom plate portion 261, and is movable. The base part 203 can be manufactured easily.

  Next, the usage method and the effect of the fixing means 400 will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 400, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 from the front of the substrate box 102.

  When the distal end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330, the inclined surface 305 b of the proximal end side locking claw 305 becomes the second insertion hole 333. The state is in contact with the front end surface.

  In this state, by further pressing the fixing pin 301, the proximal end side locking claws 305 are urged in a direction in which the inclined surfaces 305a abut against the front end surface of the second insertion hole 333 and approach each other. When the maximum distance between the pair of proximal end side locking claws 305 is elastically deformed to a position smaller than the inner diameter of the second insertion hole 333, the second insertion hole 333 passes through the second insertion hole 333. It protrudes in the axial direction from the rear end surface 330a.

  When the proximal end side locking claw 305 passes through the second insertion hole 333 and protrudes in the axial direction from the rear end surface 330a of the second inserted member 330, the urging force by the second insertion hole 333 is released and restored. Then, the bending returns to the original, and the stepped surface 305 b of the proximal end side locking claw 305 is disposed at a position facing the rear end surface 330 a of the second inserted member 330.

  On the other hand, when the fixing pin 301 is pushed in, the distal end side claw 304 is urged in a direction in which the inclined surface 304 a comes into contact with the front end surface of the first insertion hole 403 and approaches each other. When the maximum distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 403, the first insertion hole 403 passes through the first insertion hole 403 and from the rear end surface 402a of the convex portion 402. Also protrudes in the axial direction.

  When the distal end side claw 304 passes through the first insertion hole 403 and protrudes in the axial direction from the rear end surface 402a of the convex portion 402, the urging force by the first insertion hole 403 is released, and is restored and bent. Returning to the original position, the step surface 304b of the front end side claw 304 is disposed at a position facing the rear end surface 402a of the convex portion 402.

  At this position, the flange portion 303 of the fixing pin 301 is accommodated in the enlarged diameter portion 334 of the second insertion hole 333, and the bottom surface of the flange portion 303 is substantially flush with the front end surface of the second inserted member 330. Placed in position. And the collar part 303 opposes the level | step difference surface 334a of the enlarged diameter part 334, and the movement to the further insertion direction of the fixing pin 301 is controlled.

  Here, when the fixing pin 301 is moved in the removal direction opposite to the insertion direction, the stepped surface 304b of the front end side claw 304 comes into contact with the rear end surface 402a of the convex portion 402, and the base The step surface 305b of the end-side locking claw 305 comes into contact with the rear end surface 330a of the second inserted member 330, and the movement of the fixing pin 301 in the extraction direction is stopped.

  That is, the thin shaft portion 302 b of the fixing pin 301 is inserted and locked in the first insertion hole 403 of the first inserted member 401, and the thick shaft portion 302 a is inserted into the second insertion hole 333 of the second inserted member 330. Thus, the fixing pin 301 cannot be removed from the first inserted member 401 and the second inserted member 330.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 300 described above, first, the second inserted member 330 to which the fixing pin 301 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 330 from the back case body 120, the gate portion 331 supporting the second inserted member 330 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 301 is removed from the first inserted member 401 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of front end side locking claws 304 protruding from the first insertion hole 403 to the back surface side of the bottom plate portion 261 is urged in the direction approaching each other to be elastically deformed. The separation distance is narrowed to a position where it is smaller than the inner diameter of the first insertion hole 403, the opposing of the rear end surface 402 a of the convex portion 402 and the stepped surface 304 a of the front end side locking claw 304 is released, and Release the lock. Then, the fixing pin 301 is moved relative to the first inserted member 401 in the axial direction and in a direction in which the fixing pin 301 is withdrawn relative to the first insertion member 401, and the distal end side claw 304 is passed through the first insertion hole 403. Is removed from the first inserted member 401.

  As a result, the fixing pin 301 is taken out from the board box 102 and the pedestal device 201 in a state where the second inserted member 330 is fitted on the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 301 is reused, the second inserted member 330 is removed from the fixing pin 301. In order to remove the second inserted member 330 from the fixing pin 301, the proximal end side locking claws 305 protruding from the second insertion hole 333 of the second inserted member 330 and exposed are urged in a direction approaching each other. Then, the hook to the second inserted member 330 is removed, and the fixing pin 301 is urged in the direction to be pulled out as it is. Thereby, the inside of the 2nd insertion hole 333 can be passed in the state which bent the base end side latching claw 305 in the direction which approaches mutually.

  The pair of distal end side locking claws 304 can pass through the second insertion hole 333 as it is because the maximum separation distance is smaller than the outer diameter of the thick shaft portion 302a. Therefore, after the thick shaft portion 302a is removed from the second inserted member 330, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 330 can be easily detached from the fixing pin 301 without destroying the fixing pin 301.

  According to the fixing means 400, the fixing pin 301 covers the base end side locking claw 305 with the first inserted member 401 when the substrate box 102 and the movable base portion 203 are fixed. Therefore, for example, even if a release operation for releasing the locking to the first inserted member 401 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 301, the proximal-side locking claw 305 is not Since it is locked to the second inserted member 330 in a state of being covered with the first inserted member 401, the locking of the proximal end side locking claw 305 cannot be released, and the fixing pin 301 Unauthorized removal can be prevented.

  On the other hand, when the second inserted member 330 is separated from the board box 102 and the locking of the front end side claw 304 to the first inserted member 401 is released and the fixing pin 301 is taken out from the main board unit 100, The proximal end side locking claw 305 of the fixing pin 301 is exposed while being locked to the second inserted member 330. Then, the proximal-side latching claw release operation for releasing the latching to the second inserted member 330 by urging the proximal-side latching claws 305 toward each other becomes possible.

  Therefore, the base end side locking claw 305 is operated to release the base end side locking claw releasing operation to release the locking to the second inserted member 330 and the second inserted member 330 is removed from the fixing pin 301. The fixing pin 301 can be easily removed without being damaged or damaged in a reusable state.

(Third embodiment)
FIG. 27 is a diagram schematically showing the configuration of the fixing means 410 in the third embodiment. Note that the same components as those in the above-described embodiments are given the same reference numerals, and detailed description thereof is omitted.

  In the second embodiment described above, the configuration in which the entire base end side locking claw 305 protrudes from the second inserted member 330 and is exposed when the first inserted member 401 is removed from the fixing pin 301 will be described as an example. However, in the present embodiment, a configuration in which a part of the proximal end side locking claw 305 protrudes from the second inserted member 330 and is exposed will be described as an example.

  The fixing means 410 in the present embodiment includes a fixing pin 301, a first inserted member 411, and a second inserted member 421. The first inserted members 411 are formed integrally with the bottom plate portion 261 of the movable base portion 203, and are arranged in a total of four in the left and right rows at the upper center of the bottom plate portion 261.

  The first inserted member 411 has a convex portion 412 that protrudes rearward from the back surface of the bottom plate portion 261. The convex portion 412 has a cylindrical shape having a constant diameter and extending in the axial direction. A first insertion hole 413 is formed along the axial direction at a substantially central position of the convex portion 412.

  In the first insertion hole 413, the rear end of the first insertion hole 413 is opened on the rear end surface 412 a of the convex portion 412. The first insertion hole 413 is slightly larger than the outer diameter of the thin shaft portion 302b so as to form a slight gap with the outer peripheral surface of the thin shaft portion 302b when the thin shaft portion 302b of the fixing pin 301 is inserted. And it has an inner diameter smaller than the maximum separation distance of a pair of front end side latching claws 304. Further, the axial length of the thin shaft portion 302b is approximately equal to the length of the thin shaft portion 302b so that the front end side locking claw 304 protrudes from the first insertion hole 413 and the stepped surface 304a of the front end side locking claw 304 faces the rear end surface 412a of the convex portion 412. They have the same or slightly shorter axial length.

  Then, when the thin shaft portion 302 b of the fixing pin 301 is inserted into the first insertion hole 413, the rear end surface 412 a of the convex portion 412 is opposed to the distal end side claw 304 on the side of the fixing pin 301 in the removal direction. When the fixing pin 301 is biased in the removal direction, the stepped surface 304a of the front end side claw 304 is brought into contact with the rear end surface 412a of the convex portion 412 so that the fixing pin 301 is removed. The fixing pin 301 can be locked.

  A housing portion 414 is formed in the front portion of the first insertion hole 413 in the axial direction. The accommodating portion 414 is formed with a stepped diameter between the first insertion hole 413 and opens to the front end surface 411a of the first inserted member 411 that is flush with the surface of the bottom plate portion 261. ing.

  The accommodating portion 414 has a proximal end side locking claw 305 when the thin shaft portion 302b of the fixing pin 301 is inserted into the first insertion hole 403 and the distal end side locking claw 304 is locked to the first inserted member 411. An inner diameter that is the same as or slightly wider than the maximum separation distance of the pair of base end side locking claws 305 and an axis that is shorter than the axial length of the base end side locking claws 305 It has a directional length.

  When the fixing pin 301 is removed from the first inserted member 411, the pair of front end side locking claws 304 protruding in the axial direction from the rear end surface 412a of the convex portion 412 are urged in a direction approaching each other. It is elastically deformed and narrowed to a position where the maximum separation distance between the pair of front end side locking claws 304 is smaller than the inner diameter of the first insertion hole 413. Then, the opposing of the rear end surface 412a of the convex portion 412 and the stepped surface 304a of the front end side locking claw 304 is released to release the front end side locking claw 304 from being locked and fixed to the first inserted member 411. The fixed pin 301 is removed from the first inserted member 411 by moving the pin 301 in the axial direction and the direction in which the pin 301 is relatively removed and passing the distal end side locking claw 304 through the first insertion hole 413. can do.

  Since the first inserted member 411 is recessed along a direction orthogonal to the bottom plate portion 261, the first inserted member 411 can be formed by a mold sandwiched from the front surface side and the back surface side of the bottom plate portion 261, and is movable. The base part 203 can be manufactured easily.

  The second inserted member 421 is provided integrally with the back case body 120 of the board box 102. When the substrate box 102 is mounted on the movable base portion 203, the substrate box 102 is provided so as to face the first inserted member 411 of the movable base portion 203 on the front side in the axial direction.

  The second inserted member 421 has a cylindrical shape with a certain thickness, and its central axis extends along a direction perpendicular to the sliding movement direction of the substrate box 102 with respect to the pedestal device 201. It is supported in the square hole portion 123 of the back case body 120 by a gate portion 331 (see, for example, FIG. 24).

  The second inserted member 421 has the same axial length as the axial length from the proximal end of the fixing pin 301 to the midway position of the inclined surface 305 b of the proximal locking claw 305. A second insertion hole 423 is formed in the center of the second inserted member 421.

  The second insertion hole 423 has a round hole shape having a constant diameter and extending in the axial direction. When the thick shaft portion 302a of the fixing pin 301 is inserted, the second insertion hole 423 is in contact with the outer peripheral surface of the thick shaft portion 302a. The inner diameter is slightly larger than the outer diameter of the thick shaft portion 302a and smaller than the maximum separation distance of the pair of base end side locking claws 305 so that a slight gap can be formed therebetween.

  Then, the base end side locking claw 305 protrudes from the second insertion hole 423, and the step surface 305 a of the base end side locking claw 305 is a rear side step between the second insertion hole 423 and the storage portion (second storage portion) 425. It has an axial length substantially the same as or slightly shorter than the axial length of the thick shaft portion 302a so as to face the surface 425a.

  A diameter-expanded portion 424 is formed in the front portion of the second insertion hole 423 in the axial direction. The diameter-expanded portion 424 is formed to have a diameter increased between the second insertion hole 423 and the front-side step surface 424a, and is open to the front end surface 421b of the second inserted member 421.

  The enlarged diameter portion 424 is configured so that the entire flange portion 303 is formed when the thick shaft portion 302 a of the fixing pin 301 is inserted into the second insertion hole 333 and the proximal end side locking claw 305 is locked to the second inserted member 330. In order to be accommodated, it has an inner diameter that is slightly larger than the outer diameter of the flange 303 and an axial length that is the same as or slightly longer than the axial length of the flange 303.

  A receiving portion 425 is formed in the axially rear portion of the second insertion hole 423. The accommodating portion 425 is formed to have a diameter increased between the second insertion hole 423 via a rear step surface 425 a and opens to the front end surface 421 b of the first inserted member 421.

  The accommodating portion 425 includes the thin shaft portion 302b of the fixing pin 301 inserted into the first insertion hole 413, the distal end side locking claw 304 locked to the first inserted member 411, and the thick shaft portion of the fixing pin 301. When 302a is inserted in the 2nd insertion hole 333 and the base end side latching claw 305 is latched by the 2nd inserted member 330, it cooperates with the accommodating part 414 of the 1st inserted member 411, and a fixed pin The inner diameter of the pair of base end side locking claws 305 is slightly larger than the maximum separation distance of the pair of base end side locking claws 305 and the axial length of the base end side locking claws 305 is shorter than the base end side locking claws 305. It has an axial length.

  Therefore, when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 333, the rear side step surface 425a of the second inserted member 421 is made to the step surface 305a of the proximal end side locking claw 305. When the fixing pin 301 is urged in the removal direction, the stepped surface 305a of the proximal end side locking claw 305 becomes the rear stepped surface 425a of the second inserted member 421. The fixed pin 301 can be locked by restricting the movement of the fixed pin 301 in the removal direction. Further, the collar portion 303 is accommodated in the enlarged diameter portion 424 and abuts against the front side step surface 424a, so that the fixing pin 301 is further prevented from moving in the insertion direction and can be positioned at a predetermined insertion position. .

  When the fixing pin 301 is removed from the second inserted member 421, the distal end portions of the pair of proximal locking claws 305 projecting from the rear end surface 421a of the second inserted member 421 are moved closer to each other. To be elastically deformed and narrowed to a position where the maximum separation distance between the pair of proximal end side locking claws 305 is smaller than the inner diameter of the second insertion hole 423. Then, the opposite of the rear step surface 425a of the second inserted member 421 and the step surface 305a of the base end side locking claw 305 is released, and the fixing pin 301 is axially moved with respect to the second inserted member 421. The fixing pin 301 can be removed from the second inserted member 421 by moving the proximal end side locking claw 305 through the second insertion hole 423 by relatively moving in the direction of removal.

  In addition, since the maximum separation distance of the pair of front end side locking claws 304 is smaller than the outer diameter of the thick shaft portion 302a, the second insertion hole 423 can be passed as it is, and the second inserted member 421 can be passed through the thick shaft. After the portion 302a is removed, the thin shaft portion 302b can be continuously removed. Therefore, the fixing pin 301 can be easily detached from the second inserted member 421 without destroying the fixing pin 301.

  Next, a method of using the fixing means 410 and an operation effect will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 410, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 301 is inserted into the second insertion hole 423 of the second inserted member 421 from the front of the substrate box 102.

  When the distal end portion of the fixing pin 301 is inserted into the second insertion hole 423 of the second inserted member 421, the inclined surface 305b of the proximal locking claw 305 contacts the front step surface 424a. It will be in contact.

  From this state, by further pressing the fixing pin 301, the proximal end side locking claws 305 are urged in a direction approaching each other. When the maximum distance between the pair of proximal end side locking claws 305 is elastically deformed to a position smaller than the inner diameter of the second insertion hole 423, the second insertion hole 423 passes through the second insertion member 421. It protrudes in the axial direction from the rear step surface 425a.

  When the proximal end side locking claw 305 passes through the second insertion hole 423 and protrudes in the axial direction from the rear step surface 425a of the second inserted member 421, the urging force by the second insertion hole 423 is released. Then, the bending is restored to the original, and the step surface 305b of the proximal end side locking claw 305 is disposed at a position facing the rear step surface 425a of the second inserted member 421.

On the other hand, when the fixing pin 301 is pushed in, the distal end side claw 304 is urged in the direction in which the inclined surface 304 a comes into contact with the front end surface of the first insertion hole 413 and approaches the front end surface. When the maximum separation distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 413, the first insertion hole 413 passes through the first insertion hole 413 and from the rear end surface 412 a of the convex portion 412. Also protrudes in the axial direction.
When the front end side claw 304 passes through the first insertion hole 413 and protrudes in the axial direction from the rear end surface 412a of the convex portion 412, the biasing force by the first insertion hole 413 is released, and it is restored and bent. Returning to the original position, the stepped surface 304b of the front end side claw 304 is disposed at a position facing the rear end surface 412a of the convex portion 412.

  At this position, the collar portion 303 of the fixing pin 301 is inserted into the second insertion hole 423, and the bottom surface of the collar portion 303 is disposed at a position that is substantially flush with the front end surface of the second inserted member 421. . And the collar part 303 faces the front side level | step difference surface 424a of the 2nd to-be-inserted member 421, and the movement to the further insertion direction of the fixing pin 301 is controlled.

  Here, when the fixing pin 301 is moved in the removal direction opposite to the insertion direction, the stepped surface 304b of the front end side locking claw 304 abuts the rear end surface 412a of the convex portion 412 and The step surface 305b of the end side locking claw 305 contacts the rear step surface 425a of the second inserted member 421, and the movement of the fixing pin 301 in the pulling direction is stopped.

  That is, the thin shaft portion 302 b of the fixing pin 301 is inserted and locked in the first insertion hole 413 of the first inserted member 411, and the thick shaft portion 302 a is inserted into the second insertion hole 423 of the second inserted member 421. Thus, the fixing pin 301 can be brought into a state in which it cannot be removed from the first inserted member 411 and the second inserted member 421.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 410 described above, first, the second inserted member 421 on which the fixing pin 301 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 421 from the back case body 120, the gate part 331 supporting the second inserted member 421 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 301 is removed from the first inserted member 411 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of front end side locking claws 304 protruding from the first insertion hole 413 to the back surface side of the bottom plate portion 261 are urged in the direction of approaching each other to be elastically deformed. The separation distance is narrowed to a position where it is smaller than the inner diameter of the first insertion hole 413, and the opposing of the rear end surface 412a of the convex portion 412 and the stepped surface 304a of the front end side locking claw 304 is released to Release the lock. Then, the fixing pin 301 is moved in the axial direction relative to the first insertion member 411 so as to be removed from the first insertion member 411, and the distal end side locking claw 304 is passed through the first insertion hole 413. Is removed from the first inserted member 411.

  Thereby, the fixing pin 301 is taken out from the board box 102 and the base device 201 in a state where the second inserted member 421 is externally fitted to the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 301 is reused, the second inserted member 421 is removed from the fixing pin 301. In order to remove the second inserted member 421 from the fixing pin 301, the distal end side portions of the proximal end side locking claws 305 protruding from the rear end surface 421a of the second inserted member 421 and being exposed are attached to each other. Then, the hook to the second inserted member 421 is released, and the fixing pin 301 is urged as it is. Thereby, the inside of the 2nd insertion hole 423 can be passed in the state which bent the base end side latching claw 305 in the direction which approaches mutually.

  And since the largest separation distance of a pair of front end side latching claws 304 is smaller than the outer diameter of the thick shaft part 302a, the inside of the 2nd insertion hole 423 can be passed as it is. Therefore, after the thick shaft portion 302a is removed from the second inserted member 421, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 421 can be easily detached from the fixing pin 301 without destroying the fixing pin 301.

  According to the fixing means 400, the fixing pin 301 has the first insertion member 411 and the second insertion member 421 in the state where the base box side locking claw 305 is in a state where the substrate box 102 and the movable base portion 203 are fixed. It is covered from the outside by cooperation with. Therefore, for example, even if the release operation for releasing the locking to the first inserted member 411 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 301, the proximal-side locking claw 305 is not moved. Since it is locked to the second inserted member 421 while being concealed from the outside, the locking of the proximal end side locking claw 305 cannot be released, and unauthorized fixing of the fixing pin 301 can be prevented. Can do.

  On the other hand, when the second inserted member 421 is separated from the board box 102 and the locking of the distal end side locking claws 304 to the first inserted member 401 is released and the fixing pin 301 is taken out from the main board unit 100, The proximal end side locking claw 305 of the fixing pin 301 remains locked to the second inserted member 421, and the distal end portion of the proximal end side locking claw 305 is the rear end surface of the second inserted member 421. It protrudes from 421a and is exposed. Therefore, the proximal-side latching claw release operation for releasing the latching to the second inserted member 421 by urging the proximal-side latching claws 305 toward each other is possible.

  Accordingly, the base end side locking claw 305 is operated to release the base end side locking claw to release the locking to the second inserted member 421 and the second inserted member 421 is removed from the fixing pin 301. The fixing pin 301 can be easily removed without being damaged or damaged in a reusable state.

(Fourth embodiment)
FIG. 28 is a diagram schematically showing the configuration of the fixing means 430 in the fourth embodiment. Note that the same components as those in the above-described embodiments are given the same reference numerals, and detailed description thereof is omitted.

  In each of the above-described embodiments, an example of a configuration in which, when the first inserted member 410 is removed from the fixing pin 301, the whole or a part of the proximal end side locking claw 305 protrudes from the second inserted member 330 and is exposed. However, in the present embodiment, a configuration in which the unlocking operation can be performed from the outside in a state where the proximal end side locking claws 305 are accommodated in the second inserted member 441 will be described as an example.

  The fixing means 410 in the present embodiment includes a fixing pin 301, a first inserted member 431, and a second inserted member 441. The first inserted members 431 are formed on the bottom plate portion 261 of the movable base portion 203, and are arranged so that a total of four members are arranged in the left and right rows at the upper center of the bottom plate portion 261.

  A first insertion hole 432 is formed in the first inserted member 431. The first insertion hole 432 has a round hole shape having a constant diameter and extending in a direction perpendicular to the bottom plate portion 261, and penetrates from the front end surface 431b to the rear end surface 431a of the first inserted member 431. ing.

  The first insertion hole 432 is slightly larger than the outer diameter of the thin shaft portion 302b so as to form a slight gap with the outer peripheral surface of the thin shaft portion 302b when the thin shaft portion 302b of the fixing pin 301 is inserted. And it has an inner diameter smaller than the maximum separation distance of a pair of front end side latching claws 304. The front end side claw 304 protrudes from the first insertion hole 432, and the stepped surface 304 a of the front end side claw 304 is flush with the rear surface of the bottom plate portion 261. The rear end surface 431 a of the first inserted member 431. The axial length is substantially the same as or slightly shorter than the axial length of the thin shaft portion 302b.

  Therefore, when the thin shaft portion 302b of the fixing pin 301 is inserted into the first insertion hole 432, the rear end surface 431a of the first inserted member 431 on the side of the fixing pin 301 in the removal direction with respect to the front end side locking claw 304. Can be made to face each other. Then, when the fixing pin 301 is urged in the removal direction from such a state, the stepped surface 304a of the front end side locking claw 304 is brought into contact with the rear end surface 431a of the first inserted member 431 to fix the fixing pin 301. It is possible to restrict the movement in the pulling-out direction and to lock the fixing pin 301.

  When the fixing pin 301 is removed from the first inserted member 431, the pair of front end side locking claws 304 protruding in the axial direction from the rear end surface 431a of the first inserted member 431 are attached in a direction approaching each other. The first insertion hole 432 is narrowed to a position where the maximum separation distance between the pair of distal end side locking claws 304 is smaller than the inner diameter of the first insertion hole 432. Then, the opposing of the rear end surface 431a of the first inserted member 431 and the stepped surface 304a of the distal side locking claw 304 is released to release the locking of the distal side locking claw 304, and the first inserted member 431 is On the other hand, the fixing pin 301 is moved in the axial direction and the direction in which the fixing pin 301 is relatively removed, and the distal end side claw 304 is passed through the first insertion hole 432, whereby the fixing pin 301 is moved to the first inserted member 431. Can be removed from.

  The second inserted member 441 is provided integrally with the back case body 120 of the board box 102. When the substrate box 102 is mounted on the movable base portion 203, the substrate box 102 is provided so as to face the first inserted member 431 of the movable base portion 203 on the front side in the axial direction.

  The second inserted member 441 has a cylindrical shape with a certain thickness, and its central axis extends along a direction perpendicular to the sliding movement direction of the substrate box 102 with respect to the base device 201. It is supported in the square hole portion 123 of the back case body 120 by a gate portion 331 (see, for example, FIG. 24).

  The second inserted member 441 has an axial length substantially the same as the axial length from the proximal end of the fixing pin 301 to the distal end of the proximal locking claw 305. A second insertion hole 443 is formed in the center of the second inserted member 441.

  The second insertion hole 443 is slightly larger than the outer diameter of the thick shaft portion 302a so that a slight gap can be formed between the outer periphery of the thick shaft portion 302a when the thick shaft portion 302a of the fixing pin 301 is inserted. And it has an internal diameter smaller than the largest separation distance of a pair of base end side latching claw 305. FIG. Then, the base end side locking claw 305 protrudes from the second insertion hole 443, and the step surface 305 a of the base end side locking claw 305 faces the rear step surface 445 a between the second insertion hole 443 and the accommodating portion 445. Thus, it has an axial length substantially the same as or slightly shorter than the axial length of the thick shaft portion 302a.

  A diameter-enlarged portion 444 is formed in the front portion of the second insertion hole 443 in the axial direction. The diameter-enlarged portion 444 is formed so as to be enlarged in diameter with respect to the second insertion hole 443 through the front side step surface 444a, and is open to the front end surface 441b of the second inserted member 441. The enlarged diameter portion 444 is formed when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 443 and the proximal end side locking claw 305 is locked to the second inserted member 441. In order to be accommodated, it has an inner diameter that is slightly larger than the outer diameter of the flange 303 and an axial length that is the same as or slightly longer than the axial length of the flange 303.

  A receiving portion 445 is formed in the axially rear side portion of the second insertion hole 443. The accommodating portion 445 is formed to have a diameter increased between the second insertion hole 443 and a rear step surface 445a, and opens to the rear end surface 441a of the second inserted member 441.

  And when the board | substrate box 102 is mounted | worn with the movable base part 203, it is comprised so that it may be obstruct | occluded by the 1st member 310 to be inserted. The housing portion 445 has an inner diameter slightly larger than the maximum separation distance between the pair of base end side locking claws 305 and a base end side locking claw 305 so that the entire base end side locking claws 305 of the fixing pin 301 can be stored. The axial length is substantially the same as or slightly longer than the axial length.

  Therefore, when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 443, the rear side step surface 445a of the second inserted member 441 is made to the step surface 305a of the proximal end side locking claw 305. When the fixing pin 301 is urged in the removal direction, the stepped surface 305a of the proximal end side locking claw 305 is made to the rear stepped surface 445a of the second inserted member 441. The fixed pin 301 can be locked by restricting the movement of the fixed pin 301 in the removal direction. Further, the collar portion 303 is accommodated in the enlarged diameter portion 444 and abuts against the front side step surface 444a, so that the fixing pin 301 is further prevented from moving in the insertion direction and can be positioned at a predetermined insertion position. .

  When the fixing pin 301 is removed from the second inserted member 441, a tool or the like (not shown) is inserted into the housing portion 445 from the rear side in the axial direction of the second inserted member 441. A tool tip is interposed between the peripheral surface and the inclined surface 305b of the base end side locking claw 305 so that the pair of base end side locking claws 305 protruding from the second insertion hole 443 approach each other. It is urged and elastically deformed, and is narrowed to a position where the maximum separation distance between the pair of proximal end side locking claws 305 is smaller than the inner diameter of the second insertion hole 443. Then, the opposite of the rear step surface 445a of the second inserted member 441 and the step surface 305a of the proximal end side locking claw 305 is released, and the fixing pin 301 is axially moved with respect to the second inserted member 441. The fixing pin 301 can be removed from the second inserted member 441 by moving the base end side locking claws 305 through the second insertion hole 443 by relatively moving in the direction of removal.

  In addition, since the maximum separation distance of the pair of distal end side locking claws 304 is smaller than the outer diameter of the thick shaft portion 302a, the pair of distal end side locking claws 304 can pass through the second insertion hole 443 as they are, and the second insertion member 441 is thicker. After the shaft portion 302a is removed, the thin shaft portion 302b can be continuously removed. Therefore, the fixing pin 301 can be easily detached from the second inserted member 441 without destroying the fixing pin 301.

  Next, a method of using the fixing means 430 and its operation and effects will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 430, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 301 is inserted into the second insertion hole 443 of the second inserted member 441 from the front of the substrate box 102.

  When the distal end portion of the fixing pin 301 is inserted into the second insertion hole 443 of the second inserted member 441, the inclined surface 305b of the proximal locking claw 305 contacts the front step surface 444a. It will be in contact.

  From this state, by further pressing the fixing pin 301, the proximal end side locking claws 305 are urged in a direction approaching each other. When the maximum separation distance between the pair of proximal end side locking claws 305 is elastically deformed to a position smaller than the inner diameter of the second insertion hole 443, the second insertion hole 443 passes through the second insertion hole 443. It protrudes rearward in the axial direction from the rear step surface 445a.

  When the proximal locking claw 305 passes through the second insertion hole 443 and protrudes rearward in the axial direction from the rear stepped surface 445a of the second inserted member 441, the bias by the second insertion hole 443 is applied. It is released and restored to return to its original state, and the step surface 305b of the proximal end side locking claw 305 is disposed at a position facing the rear step surface 445a of the second inserted member 441.

  On the other hand, when the fixing pin 301 is pushed in, the distal end side claw 304 is urged in a direction in which the inclined surface 304a comes into contact with the inner peripheral surface of the first insertion hole 432 and approaches the inner surface. When the maximum distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 432, the first insertion hole 432 passes through the first insertion member 431. It protrudes rearward in the axial direction from the end face 431a.

  When the front end side claw 304 passes through the first insertion hole 432 and protrudes rearward in the axial direction from the rear end surface 431a of the first inserted member 431, the biasing force by the first insertion hole 432 is released, The bend is restored to its original state, and the stepped surface 304b of the front end side locking claw 304 is disposed at a position facing the rear end surface 431a of the first inserted member 431.

  At this position, the flange portion 303 of the fixing pin 301 is inserted into the second insertion hole 443, and the bottom surface of the flange portion 303 is disposed at a position that is substantially flush with the front end surface 441b of the second inserted member 441. The And the collar part 303 contact | abuts to the front side level | step difference surface 444a of the 2nd insertion member 441, and the movement to the further insertion direction of the fixing pin 301 is controlled.

  Here, when the fixing pin 301 is to be moved in the removal direction opposite to the insertion direction, the step surface 304b of the front end side locking claw 304 contacts the rear end surface 431a of the first inserted member 431. At the same time, the step surface 305b of the base end side locking claw 305 comes into contact with the rear step surface 445a of the second inserted member 441, and the movement of the fixing pin 301 in the pulling direction is stopped.

  And since the opening part of the axial direction rear side of the accommodating part 445 is obstruct | occluded by the 1st to-be-inserted member 431 in the state accommodated in the accommodating part 445, it touches from the outside. I can't.

  Therefore, the thin shaft portion 302 b of the fixing pin 301 is inserted and locked in the first insertion hole 432 of the first inserted member 431, and the thick shaft portion 302 a is inserted into the second insertion hole 443 of the second inserted member 441. Thus, the fixing pin 301 cannot be removed from the first inserted member 431 and the second inserted member 441.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 410 described above, first, the second inserted member 441 to which the fixing pin 301 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 441 from the back case body 120, the gate part 331 supporting the second inserted member 441 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 301 is removed from the first inserted member 431 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of front end side locking claws 304 protruding from the first insertion hole 432 toward the back surface side of the bottom plate portion 261 is urged in the direction approaching each other to be elastically deformed. The separation distance is narrowed to a position where it is smaller than the inner diameter of the first insertion hole 432, and the opposite of the rear end surface 431a of the first inserted member 431 and the stepped surface 304a of the front end side locking claw 304 is released to stop the front end side. The latch of the nail | claw 304 is cancelled | released. Then, the fixing pin 301 is moved in the axial direction relative to the first inserted member 431 so as to be relatively removed, and the distal end side claw 304 is passed through the first insertion hole 432, and the fixing pin 301 is moved. Is removed from the first inserted member 431.

  Thereby, the fixing pin 301 is taken out from the board box 102 and the base device 201 in a state where the second inserted member 441 is externally fitted to the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 301 is reused, the second inserted member 441 is removed from the fixing pin 301. In order to remove the second inserted member 441 from the fixing pin 301, the locking by the base end side locking claw 305 is released.

  Since the receiving portion 445 of the second inserted member 441 is already separated from the first inserted member 431 by removing the fixing pin 301, the opening portion on the rear side in the axial direction is opened.

  Therefore, a tool or the like is inserted into the accommodating portion 445 from the axial rear side of the second inserted member 441, and the tool is interposed between the inclined surface 305b of the proximal end side locking claw 305 and the inner peripheral surface of the accommodating portion 445. The pair of base end side latching claws 305 are biased in the direction approaching each other with the tip interposed therebetween, and the hook to the second inserted member 441 is removed, and the fixing pin 301 is biased as it is. Thereby, the inside of the 2nd insertion hole 443 can be passed in the state which bent the base end side latching claw 305 in the direction which approaches mutually.

  And since the maximum separation distance of a pair of front end side latching claw 304 is smaller than the outer diameter of the thick shaft part 302a, the inside of the 2nd insertion hole 443 can be passed as it is. Therefore, after the thick shaft portion 302a is removed from the second inserted member 441, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 441 can be easily detached from the fixing pin 301 without destroying the fixing pin 301.

  According to the fixing means 430, the fixing pin 301 has the first insertion member 431 and the second insertion member 441 in the state where the base end side locking claw 305 is in a state where the substrate box 102 and the movable base portion 203 are fixed. It is covered from the outside by cooperation with. Therefore, for example, even if the release operation for releasing the locking to the first inserted member 410 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 301, the proximal-side locking claw 305 is Since it is locked to the second inserted member 441 in a state of being covered from the outside, the locking of the proximal end side locking claw 305 cannot be released, and unauthorized fixing of the fixing pin 301 can be prevented. Can do.

  On the other hand, when the second inserted member 441 is separated from the board box 102 and the locking of the distal end side locking claws 304 to the first inserted member 431 is released, the fixing pin 301 is taken out from the main board unit 100. The housing portion 445 of the second inserted member 441 is opened on the rear side in the axial direction.

  Accordingly, a tool or the like is inserted between the inclined surface 305 b of the base end side locking claw 305 and the inner peripheral surface of the storage portion 445 and is stored in the storage portion 445 in a state of protruding from the second insertion hole 443. The pair of base end side latching claws 305 can be urged toward each other to remove the catch on the second inserted member 441.

(Fifth embodiment)
FIG. 29 is a diagram schematically showing the configuration of the fixing means 450 in the fifth embodiment. Note that the same components as those in the above-described embodiments are given the same reference numerals, and detailed description thereof is omitted.

  What is characteristic in the present embodiment is that the front-end-side locking claws 304 of the fixing pin 451 are provided apart from each other in the axial direction and locked to the first inserted members 461, respectively. is there.

  The fixing means 450 in the present embodiment includes a fixing pin 451, a first inserted member 461, and a second inserted member 330.

  The fixing pin 451 is made of a synthetic resin material such as polycarbonate having a predetermined rigidity, and includes a shaft portion 302, a first distal end side locking claw 453, a second distal end side locking claw 454, and a proximal end side engagement. It has a pawl 305.

  The first tip side locking claw 453 is provided at the tip portion of the thin shaft portion 302b, and the second tip side locking claw 454 is provided at a substantially central position in the longitudinal direction of the thin shaft portion 302b. The first distal side locking claw 453 and the second distal side locking claw 454 are each in a direction away from the thin shaft portion 302b with the slit 306 therebetween and in the same direction as the proximal side locking claw 305. It is paired so that it protrudes toward.

  The first distal end side locking claw 453 has a stepped surface 453a formed in a stepped shape so as to be substantially perpendicular to the thin shaft portion 302b, and a stepped surface as it moves from the axially proximal end side to the distal end side. It has a tapered inclined surface 453b that gradually decreases in diameter from the outer peripheral edge of 453a. The tip end side in the axial direction of the first tip side locking claw 304 is formed to have a smaller diameter than the outer diameter of the thin shaft portion 302b. Then, both ends in the width direction of the first tip side locking claws 453 are chamfered in parallel so as to have a width substantially the same as the width of the thin shaft portion 302b. The step surface 453a of the first tip side locking claw 453 is formed on the rear end surface 462a of the convex portion 462 of the first inserted member 461 when the thin shaft portion 302b of the fixing pin 451 is inserted into the first inserted member 461. It is formed to be able to face each other. The inclined surface 453b of the first distal end side locking claw 453 is an inner peripheral surface of the first insertion hole 463 when the thin shaft portion 302b of the fixing pin 451 is inserted into the first insertion hole 463 of the first inserted member 461. Is formed so as to urge the thin shaft portions 302b toward each other through the slit 306 therebetween.

  The second distal end side locking claw 454 has a step surface 454a formed in a step shape so as to be substantially perpendicular to the shaft portion 302, and a step surface 454a as it moves from the axially proximal end side to the distal end side. It has a tapered inclined surface 454b that gradually decreases in diameter from the outer periphery. The tip end side in the axial direction of the second tip side locking claw 454 is formed to have the same diameter as the outer diameter of the thin shaft portion 302b. Then, both ends in the width direction of the second tip side locking claws 454 are chamfered in parallel so as to have a width substantially the same as the width of the thin shaft portion 302b. The step surface 454a of the second tip side locking claw 454 is a step in an insertion hole 465 of the first inserted member 461 described later when the thin shaft portion 302b of the fixing pin 451 is inserted into the first inserted member 461. It is formed so as to face the surface 465a. The inclined surface 454b of the second distal end side locking claw 454 is the inner peripheral surface of the first insertion hole 463 when the thin shaft portion 302b of the fixing pin 451 is inserted into the first insertion hole 463 of the first inserted member 461. Is formed so as to urge the thin shaft portions 302b toward each other through the slit 306 therebetween.

  The shaft portion 302 moves toward each other by urging at least one of the first distal end side locking claws 453 and the second distal end side locking claws 454 in a direction approaching each other with the slit 306 interposed therebetween. Further, the elastic strength is set so that it can be restored to the original position by disappearance of the urging force. Even if at least one of the first distal end side locking claws 453 and the second distal end side locking claws 454 is picked from the outside via the slit 306 and biased in a direction approaching each other, each proximal end The side latching claws 305 can be maintained in a state of being latched to the second inserted member 330, and the claw portions 304b of the respective base end side latching claws 304 are gripped from the radially outer side and attached in a direction approaching each other. The elastic strength is set so that the base end side locking claw 305 can be unlocked with respect to the second inserted member 330 when it is biased.

  The pair of first tip side locking claws 453 and the pair of second tip side locking claws 454 are both formed such that the maximum separation distance in the direction orthogonal to the axial direction is equal to or less than the thick shaft portion 302a. When the thin shaft portion 302b of the fixing pin 451 is moved in a direction to be removed from the second insertion hole 333 of the second inserted member 330, the second insertion hole 330 is not caught by the second insertion hole 330. 333 can pass through.

  Both the first tip side locking claw 453 and the second tip side locking claw 454 are formed so as to be located radially inward from the outer peripheral surface of the thick shaft portion 302a. In other words, the first distal end side locking claw 453 and the second distal end side locking claw 454 have a radial distance from the center of the thin shaft portion 302b to the maximum protruding portion that is equal to or smaller than the radius of the thick shaft portion 302a. It is set so that it does not protrude outward in the radial direction from the outer peripheral surface of the thick shaft portion 302a.

  The first inserted members 461 are formed on the bottom plate portion 261 of the movable base portion 203, and a total of four members are arranged in a line on the left and right in the upper center of the bottom plate portion 261. The first inserted member 461 has a convex portion 462 that protrudes rearward from the rear surface 261 a of the bottom plate portion 261. The convex portion 462 has a cylindrical shape having a constant diameter and extending in the axial direction, and a first insertion hole 463 is formed at a substantially central position of the convex portion 462.

  The first insertion hole 463 has a round hole shape having a constant diameter and extending in the axial direction, and opens to the rear end surface 462a of the convex portion 462 of the first inserted member 461. The first insertion hole 463 is slightly larger than the outer diameter of the thin shaft portion 302b so as to form a slight gap with the outer peripheral surface of the thin shaft portion 302b when the thin shaft portion 302b of the fixing pin 451 is inserted. And it has an inner diameter smaller than the maximum separation distance between the first tip side locking claw 453 and the second tip side locking claw 454.

  Then, the shaft of the thin shaft portion 302b is arranged such that the first front end side locking claw 453 protrudes from the first insertion hole 463 and the step surface 453a of the first front end side locking claw 453 faces the rear end surface 462a of the convex portion 462. The axial length is substantially the same as or slightly shorter than the directional length.

  Then, when the thin shaft portion 302b of the fixing pin 451 is inserted into the first insertion hole 463, the rear end surface 462a of the convex portion 462 is formed on the side of the fixing pin 451 in the removal direction with respect to the first distal end side locking claw 453. When the fixing pin 451 is urged in the removal direction, the step surface 453a of the first distal end side locking claw 453 is brought into contact with the rear end surface 462a of the convex portion 462 so that the fixing pin 451 The movement in the pulling-out direction is restricted, and the fixing pin 451 can be locked.

  An engaging hole 465 is formed with an enlarged diameter at an intermediate position in the axial direction of the first insertion hole 463. The engagement holes 465 are a pair of second distal end side locking claws so that the second distal end side locking claws 454 are engaged when the thin shaft portion 302 b of the fixing pin 451 is inserted into the first insertion hole 463. It has an inner diameter that is larger than the maximum separation distance of 454 and an axial length that is substantially the same as or slightly longer than the axial length of the second tip side locking claw 454.

  When the thin shaft portion 302 b of the fixing pin 451 is inserted into the first insertion hole 463, the step surface in the insertion hole 465 on the removal direction side of the fixing pin 451 with respect to the second distal end side locking claw 454. 465a can be made to face each other, and when the fixing pin 451 is urged in the removal direction, the step surface 454a of the second distal end side locking claw 454 is brought into contact with the step surface 465a of the engagement hole 465. The movement of the fixing pin 451 in the removal direction is restricted, and the fixing pin 451 can be locked.

  A housing portion 464 is formed in the front portion of the first insertion hole 463 in the axial direction. The accommodating portion 464 is formed to have a diameter increased through a step between the first insertion hole 463 and opens to the front end surface 461a of the first inserted member 461 that is flush with the surface of the bottom plate portion 261. ing.

  In the accommodating portion 464, the thin shaft portion 302b of the fixing pin 451 is inserted into the first insertion hole 463, and the first tip side locking claw 453 and the second tip side locking claw 454 are locked to the first inserted member 401. In order to accommodate the entirety of the base end side locking claws 305 in the case of being done, an inner diameter equal to or slightly wider than the maximum separation distance of the pair of base end side locking claws 305 and the axial direction of the base end side locking claws 305 The axial length is the same as or slightly longer than the length.

  When the fixing pin 451 is removed from the first inserted member 461, the pair of first front end side locking claws 453 protruding in the axial direction from the rear surface 261a of the bottom plate portion 261 is urged in a direction approaching each other. The first distal side locking claw 453 and the second distal side locking claw 454 are narrowed to a position where the maximum separation distance is smaller than the inner diameter of the first insertion hole 463. Then, the rear end surface 462a of the convex portion 462 and the step surface 453a of the first front end side locking claw 453, and the step surface 465a of the engagement hole 465 and the step surface 454a of the second front end side locking claw 454 are formed. The opposite is released, the locking to the first inserted member 401 is released, and the fixing pin 451 is moved relative to the first inserted member 461 in the axial direction and in a relatively withdrawing direction. The fixing pin 451 can be removed from the first inserted member 461 by passing the distal end side locking claw 453 and the second distal end side locking claw 454 through the first insertion hole 463.

  Next, a method of using the fixing means 450 and an operation effect will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 450, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 451 is inserted into the second insertion hole 333 of the second inserted member 330 from the front of the substrate box 102.

  When the distal end side portion of the fixing pin 451 is inserted into the second insertion hole 333 of the second inserted member 330, the inclined surface 305 b of the proximal locking claw 305 becomes the second inserted member 330. It is set as the state contact | abutted to the front side level | step difference surface 334a.

  From this state, by further pressing the fixing pin 451, the proximal end side locking claws 305 are urged in a direction approaching each other. When the maximum distance between the pair of proximal end side locking claws 305 is elastically deformed to a position smaller than the inner diameter of the second insertion hole 333, the second insertion hole 333 passes through the second insertion hole 333. It protrudes rearward in the axial direction from the rear end surface 330a. When the proximal end side locking claw 305 passes through the second insertion hole 333 and protrudes rearward in the axial direction from the rear end surface 330a of the second inserted member 330, the biasing force by the second insertion hole 333 is released. Then, the bending is restored to the original state, and the step surface 305b of the proximal end side locking claw 305 is disposed at a position facing the rear end surface 330a of the second inserted member 330.

  On the other hand, when the fixing pin 451 is pushed in, the pair of first tip side locking claws 453 are biased in a direction in which the inclined surface 453 b comes into contact with the inner peripheral surface of the first insertion hole 463 and approaches each other. When the maximum distance between the pair of first front end side locking claws 453 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 463, the first insertion hole 463 passes through the rear end surface of the convex portion 462. Projects axially rearward of 462a. When the pair of first front end side locking claws 453 pass through the first insertion hole 463 and protrude rearward in the axial direction from the rear end surface 462a of the convex portion 462, the biasing by the first insertion hole 463 is released. Then, the bending is restored to the original, and the step surface 453b of the first front end side locking claw 453 is disposed at a position facing the rear end surface 462a of the convex portion 462.

  Further, when the pair of first tip side locking claws 453 is inserted into the first insertion hole 463 by pushing the fixing pin 451 described above, the pair of second tip side locking claws 454 are paired. The side locking claw 454 is elastically deformed to a position where the maximum separation distance becomes smaller than the inner diameter of the first insertion hole 463, and is inserted into the first insertion hole 463. Then, the first front end side locking claw 453 passes through the first insertion hole 463 and protrudes rearward in the axial direction from the rear end surface 462a of the convex portion 462, and coincides with the position of the engagement hole 465, The biasing force by the first insertion hole 463 is released, restored, and the bending returns, and the projection protrudes into the engagement hole 465. The step surface 454b of the second distal end side locking claw 454 faces the step surface 465a of the engagement hole 465. It is arranged at the position to do.

  At this position, the collar portion 303 of the fixing pin 451 is inserted into the second insertion hole 333, and the bottom surface of the collar portion 303 is disposed at a position that is substantially flush with the front end surface 330b of the second inserted member 330. The And the collar part 303 contact | abuts to the front side level | step difference surface 334a of the 2nd insertion member 330, and the movement to the further insertion direction of the fixing pin 451 is controlled.

  When the fixing pin 451 is moved in the removal direction opposite to the insertion direction, the step surface 453b of the first distal end side locking claw 453 contacts the rear end surface 462a of the convex portion 462, and the first 2 The stepped surface 454b of the front end side locking claw 454 contacts the stepped surface 465a of the engagement hole 465, and the stepped surface 305b of the proximal end side locking claw 305 contacts the rear end surface 330a of the second inserted member 330. In contact therewith, the movement of the fixing pin 451 in the pull-out direction is stopped.

  Further, the proximal end side locking claw 305 is accommodated in the accommodating portion 464 of the first inserted member 461 and cannot be touched from the outside. Therefore, the thin shaft portion 302 b of the fixing pin 451 is inserted and locked in the first insertion hole 463 of the first inserted member 461, and the thick shaft portion 302 a is inserted into the second insertion hole 333 of the second inserted member 330. Thus, the fixing pin 451 cannot be removed from the first inserted member 461 and the second inserted member 330.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 410 described above, first, the second inserted member 330 to which the fixing pin 451 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 330 from the back case body 120, the gate portion 331 supporting the second inserted member 330 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 451 is removed from the first inserted member 461 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of first tip side locking claws 453 protruding from the first insertion hole 463 to the back surface side of the bottom plate portion 261 is urged in a direction approaching each other to be elastically deformed.

  The maximum distance between the pair of first tip side locking claws 453 and the maximum distance between the pair of second tip side locking claws 454 are narrowed to a position smaller than the inner diameter of the first insertion hole 463, The opposite end of the rear end surface 462a of the 462 and the step surface 453a of the first front end side locking claw 453 is released, and the step surface 465a of the engagement hole 465 and the step surface 454a of the second front end side locking claw 454 are released. The facing is released, and the locking of the first inserted member 461 by the first tip side locking claw 453 and the second tip side locking claw 454 is released. Then, the fixing pin 451 is moved in the axial direction relative to the first insertion member 461 so as to be withdrawn relative to the first insertion member 461, and the distal end side locking claw 304 is passed through the first insertion hole 463. Is removed from the first inserted member 461.

  Thereby, the fixing pin 451 is taken out from the board box 102 and the pedestal device 201 in a state where the second inserted member 330 is externally fitted to the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 451 is reused, an operation of removing the second inserted member 330 from the fixing pin 451 is performed. In order to remove the second inserted member 330 from the fixing pin 451, the pair of proximal end side locking claws 305 protruding from the second inserted member 330 and exposed are biased in a direction approaching each other, and the second The hook to the member to be inserted 330 is released, and the locking to the second member to be inserted 330 by the proximal end side locking claw 305 is released. Then, the fixing pin 301 is urged in the direction in which it is pulled out to pass through the second insertion hole 333.

  The pair of distal end side locking claws 304 can pass through the second insertion hole 333 as they are because the maximum separation distance is smaller than the outer diameter of the thick shaft portion 302a. Therefore, after the thick shaft portion 302a is removed from the second inserted member 330, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 330 can be easily detached from the fixing pin 451 without destroying the fixing pin 451.

  According to the fixing means 450, the fixing pin 451 is accommodated in the accommodating portion 464 of the first inserted member 461 in the state where the substrate box 102 and the movable base portion 203 are fixed. Has been hidden from the outside. Therefore, for example, even if the release operation for releasing the locking to the first inserted member 410 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 451, The locking cannot be released, and unauthorized removal of the fixing pin 451 can be prevented.

  On the other hand, when the second inserted member 330 is separated from the board box 102 and the locking of the distal end side locking claws 304 to the first inserted member 461 is released, the fixing pin 451 is taken out from the main board unit 100. The proximal end side claw 305 of the fixing pin 451 is exposed from the second inserted member 330.

  Therefore, the pair of base end side latching claws 305 can be urged in the direction approaching each other, and the catch on the second inserted member 330 can be removed. Then, the second inserted member 330 can be removed from the fixing pin 451 by urging the fixing pin 451 in the direction in which the fixing pin 451 is pulled out, and the fixing pin 451 can be easily reused without being damaged or damaged. Can be removed.

  The step surface 473a of the first base end side locking claw 473 is formed after the second inserted member 481 when the thick shaft portion 302a of the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481. It is formed so as to be opposed to the end surface 481a. The inclined surface 473b of the first base end side locking claw 473 is formed so that the inner periphery of the second insertion hole 483 is inserted when the thick shaft portion 302a of the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481. It is formed so as to abut against the surface and urge the thick shaft portions 302a toward each other through the slit 306 therebetween.

It has a tapered inclined surface 474b that gradually decreases in diameter from the outer peripheral edge of 474a.

  Both ends in the width direction of the second base end side locking claws 474 are chamfered in parallel so as to have a width substantially the same as the width of the thick shaft portion 302a. The step surface 474a of the second base end side locking claw 474 engages with the first insertion hole 483 when the thick shaft portion 302a of the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481. The hole 485 is formed so as to be opposed to the step surface 485a. The inclined surface 474b of the second base end side locking claw 474 has an inner periphery of the second insertion hole 483 when the thick shaft portion 302b of the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481. It is formed so as to abut against the surface and urge the thick shaft portions 302a toward each other through the slit 306 therebetween.

  The shaft portion 302 is moved in the direction approaching each other by urging the slits 306 in the direction approaching each other via the slit 306, and can be restored by the disappearance of the urging force and returned to the original position. Elastic strength is set. And when the front end side claw 304 is pinched from the outside via the slit 306 and urged in the direction of approaching each other, the locking to the first inserted member 401 can be released, but the first base end side The locking claw 473 and the second proximal-side locking claw 474 are maintained in a state of being locked to the second inserted member 481, and the first proximal-side locking claw 473 and the second proximal-side locking claw 473 and the second inserted member 481 are maintained. The two base end side locking claws 474 are set so as not to be unlocked. When the first base end side locking claws 473 are picked from the outside in the radial direction and are urged toward each other, the first base end side locking claws 473 and the second base end with respect to the second inserted member 481 are provided. Elastic strength is set so that the side locking claw 474 can be unlocked.

  The pair of leading end side locking claws 304 is set to have a maximum separation distance equal to or less than the thick shaft portion 302a, and the thin shaft portion 302b of the fixing pin 471 is connected to the second insertion hole 483 of the second inserted member 481. When it is moved in the direction of removal from the second insertion member 481, the second insertion hole 483 can be passed without being caught by the second insertion member 481.

  The second inserted member 481 is provided integrally with the back case body 120 of the board box 102. When the substrate box 102 is mounted on the movable base portion 203, the substrate box 102 is provided so as to face the first inserted member 411 of the movable base portion 203 on the front side in the axial direction.

  The second inserted member 481 has an axial length substantially the same as the axial length from the proximal end of the fixing pin 471 to the distal end of the thick shaft portion 302a. A second insertion hole 483 is provided at the center of the second inserted member 481.

  The second insertion hole 483 is slightly larger than the outer diameter of the thick shaft portion 302a so that a slight gap can be formed between the fixing shaft 471 and the outer peripheral surface of the thick shaft portion 302a when the thick shaft portion 302a of the fixing pin 471 is inserted. And it has an internal diameter smaller than the largest separation distance of a pair of 1st base end side latching claw 473. FIG. Then, the first base end side locking claw 473 protrudes from the second insertion hole 483 so that the stepped surface 473a of the first base end side locking claw 473 faces the rear end surface 481a of the second inserted member 481. The axial length is substantially the same as or slightly shorter than the axial length of the shaft portion 302a.

  At the intermediate position in the axial direction of the second insertion hole 483, an engagement hole 485 is formed with an enlarged diameter. The engaging holes 485 are a pair of second proximal end engaging portions so that the second proximal end engaging claws 474 are engaged when the thick shaft portion 302 a of the fixing pin 471 is inserted into the second insertion hole 483. It has an inner diameter larger than the maximum separation distance of the pawls 474 and an axial length that is substantially the same as or slightly longer than the axial length of the second proximal-side locking pawl 474.

  When the thick shaft portion 302 a of the fixing pin 471 is inserted into the second insertion hole 483, the second base end side locking claw 474 is engaged, and the stepped surface 474 a of the second base end side locking claw 474 is engaged. On the other hand, the stepped surface 485a in the engagement hole 485 can be opposed to the removal direction side of the fixing pin 471, and when the fixing pin 471 is urged in the removal direction, the second proximal side locking is performed. The step surface 474a of the claw 474 is brought into contact with the step surface 474a of the engagement hole 485 so that the movement of the fixing pin 471 in the removal direction is restricted, and the fixing pin 471 can be locked.

  A diameter-enlarged portion 484 is formed in the front portion of the second insertion hole 483 in the axial direction. The diameter-expanded portion 484 is formed to have a diameter increased between the second insertion hole 483 and the front step surface 484a, and is open to the front end surface 483b of the second inserted member 483.

  The enlarged diameter portion 484 has a flange portion 303 when the thick shaft portion 302 a of the fixing pin 471 is inserted into the second insertion hole 483 and the first proximal end locking claw 473 is locked to the second inserted member 481. In order to accommodate the whole, it has an inner diameter that is slightly larger than the outer diameter of the collar portion 303 and an axial length that is the same as or slightly longer than the axial length of the collar portion 303.

  Therefore, when the thick shaft portion 302a of the fixing pin 471 is inserted into the second insertion hole 483, the rear end surface 481a of the second inserted member 481 is made to be different from the step surface 473a of the first base end side locking claw 473. The stepped surface 485a of the engagement hole 485 can be disposed to face the stepped surface 474a of the second proximal end side locking claw 474.

  Then, when the fixing pin 471 is urged toward the removal direction, the stepped surface 473a of the first base end side locking claw 473 is brought into contact with the rear stepped surface 425a of the second inserted member 481, and The stepped surface 474a of the second base end side locking claw 474 is brought into contact with the stepped surface 485a of the engagement hole 485 of the second inserted member 481, thereby restricting the movement of the fixing pin 471 in the removal direction and fixing. The pin 471 can be locked.

  Further, the collar portion 303 is accommodated in the enlarged diameter portion 484 and abuts against the front side step surface 484a, so that the fixing pin 471 is further prevented from moving in the insertion direction and can be positioned at a predetermined insertion position. .

  When the fixing pin 471 is removed from the second inserted member 481, the pair of first proximal locking claws 473 projecting in the axial direction from the rear end surface 481a of the second inserted member 481 are brought closer to each other. And the maximum distance between the pair of first base end side locking claws 473 and the maximum distance between the pair of second base end side locking claws 474 are the inner diameter of the second insertion hole 483. Narrow to a smaller position.

  Then, the opposing of the rear end surface 481a of the second inserted member 481 and the stepped surface 473a of the first base end side locking claw 473 is released, and the stepped surface 485a of the engagement hole 485 of the second inserted member 481 The second base end side locking claw 474 is released from facing the step surface 474a, and the first base end side locking claw 473 and the second base end side locking claw 474 are locked to the second inserted member 481. Is released.

  Then, the fixing pin 471 is moved relative to the second inserted member 481 in the axial direction and in a relatively withdrawing direction, so that the first proximal end locking claw 473 is passed through the second insertion hole 483. Thus, the fixing pin 471 can be removed from the second inserted member 481.

  Next, a method of using the fixing means 470 and an operation effect will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 470, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481 from the front of the substrate box 102.

  When the distal end side portion of the fixing pin 471 is inserted into the second insertion hole 483 of the second inserted member 481, the inclined surface 473b of the first base end side locking claw 473 becomes the second insertion hole. It is in a state of being in contact with the axially front end portion of 483.

  From this state, by further pressing the fixing pin 471, the first base end side locking claws 473 are urged in a direction approaching each other. When the maximum distance between the pair of first base end side locking claws 473 is elastically deformed to a position smaller than the inner diameter of the second insertion hole 483, the second insertion hole 483 enters and passes through the second insertion hole 483. It protrudes rearward in the axial direction from the rear end surface 481a of the inserted member 481. When the first base end side locking claw 473 passes through the second insertion hole 483 and protrudes rearward in the axial direction from the rear end surface 481a of the second inserted member 481, the second insertion hole 483 is biased. It is released and restored to return to its original state, and the stepped surface 473a of the first base end side locking claw 473 is disposed at a position facing the rear end surface 481a of the second inserted member 481.

  Further, when the pair of base end side locking claws 473 is inserted into the first insertion hole 403 by pushing the fixing pin 471 described above, the pair of second base end side locking claws 474 is paired with the second base end side locking claws 474. The end side latching claw 474 is elastically deformed to a position where the maximum separation distance becomes smaller than the inner diameter of the second insertion hole 483 and is inserted into the second insertion hole 483. The position of the engagement hole 485 is a position where the first base end side locking claw 473 passes through the second insertion hole 483 and protrudes rearward in the axial direction from the rear end surface 481a of the second inserted member 481. , The urging force by the second insertion hole 483 is released, restored and returned to bend, projecting into the engagement hole 485, and the stepped surface 474 a of the second base end side locking claw 474 is in the engagement hole 485. It arrange | positions in the position facing the level | step difference surface 485a.

  On the other hand, when the fixing pin 471 is pushed in, the pair of distal locking claws 304 are urged in a direction in which the inclined surface 304b comes into contact with the front end portion in the axial direction of the first insertion hole 403 and approaches each other. When the maximum separation distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 403, the first insertion hole 403 enters and passes through the first insertion hole 403. It protrudes rearward in the axial direction from the end surface 402a. When the pair of leading end side locking claws 304 pass through the first insertion hole 403 and protrude rearward in the axial direction from the rear end surface 402a of the convex portion 402, the biasing force by the first insertion hole 403 is released and restored. Then, the deflection returns to the original, and the stepped surface 304b of the front end side claw 304 is disposed at a position facing the rear end surface 402a of the convex portion 402.

  At this position, the collar portion 303 of the fixing pin 471 is inserted into the second insertion hole 483, and the bottom surface of the collar portion 303 is disposed at a position that is substantially flush with the front end surface of the second inserted member 481. . And the collar part 303 contact | abuts to the front side level | step difference surface 334a of the 2nd to-be-inserted member 481, and the movement to the further insertion direction of the fixing pin 471 is controlled.

  When the fixing pin 471 is moved in the removal direction opposite to the insertion direction, the stepped surface 304a of the front end side locking claw 304 comes into contact with the rear end surface 402a of the convex portion 402, and the first base The step surface 473a of the end side locking claw 473 contacts the rear end surface 481a of the second inserted member 481, and the step surface 474a of the second base end side locking claw 474 contacts the step surface 465a of the engagement hole 465. By abutting, the movement of the fixing pin 471 in the pulling direction is stopped.

  Further, in this state, the first proximal-side locking claw 473 is accommodated and covered in the accommodation hole 404 of the first inserted member 401 and cannot be touched from the outside. Therefore, the thin shaft portion 302 b of the fixing pin 471 is inserted into and locked in the first insertion hole 403 of the first inserted member 401, and the thick shaft portion 302 a is inserted into the second insertion hole 483 of the second inserted member 481. Thus, the fixing pin 471 cannot be removed from the first inserted member 401 and the second inserted member 481.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 470, first, the second inserted member 481 to which the fixing pin 471 is locked is separated from the back case body 120 of the board box 102. In order to separate the second inserted member 481 from the back case body 120, the gate portion 331 supporting the second inserted member 481 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 471 is removed from the first inserted member 401 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of front end side locking claws 304 protruding from the first insertion hole 403 to the back surface side of the bottom plate portion 261 is urged in a direction approaching each other to be elastically deformed.

  Then, the maximum separation distance between the pair of front end side locking claws 304 is narrowed to a position smaller than the inner diameter of the first insertion hole 403, and the rear end surface 402 a of the convex portion 402 and the step surface 304 a of the front end side locking claw 304 are reduced. The opposing is released, and the locking of the first insertion member 401 by the front end side locking claw 304 is released. Then, the fixing pin 471 is moved relative to the first inserted member 401 in the axial direction and in a direction in which the fixing pin 471 is withdrawn relative to the first insertion member 401, and the distal end side locking claw 304 is passed through the first insertion hole 403. Is removed from the first inserted member 401.

  Thereby, the fixing pin 471 is taken out from the board box 102 and the pedestal device 201 in a state where the second inserted member 481 is externally fitted to the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 471 is reused, an operation of removing the second inserted member 481 from the fixing pin 471 is performed. In order to remove the second inserted member 481 from the fixing pin 471, the pair of first proximal end side locking claws 473 protruding from the rear end surface 481a of the second inserted member 481 in the axial direction and exposed are mutually connected. It is elastically deformed by urging in the approaching direction.

  Then, the maximum separation distance of the pair of first proximal locking claws 473 and the maximum separation distance of the pair of second proximal locking claws 474 are narrowed to a position smaller than the inner diameter of the second insertion hole 483, The opposing of the rear end surface 402a of the convex portion 402 and the step surface 473a of the first base end side locking claw 473 is released, and the step between the step surface 485a of the engagement hole 485 and the second base end side locking claw 474 is released. The opposing to the surface 474a is released, and the locking of the first base end side locking claws 473 and the second base end side locking claws 474 to the second inserted member 481 is released. Then, the fixing pin 471 is moved relative to the second inserted member 481 in the axial direction and in a direction in which the fixing pin 471 is withdrawn relatively, so that the first base end side locking claws 473 and the second base end side locking claws 474 are moved. Is passed through the second insertion hole 483, and the fixing pin 471 is removed from the second inserted member 481.

  Since the pair of distal end side locking claws 304 has a maximum separation distance smaller than the outer diameter of the thick shaft portion 302a, the pair of distal end side locking claws 304 can pass through the second insertion hole 483 as they are. Therefore, after the thick shaft portion 302a is removed from the second inserted member 481, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 481 can be easily detached from the fixing pin 471 without destroying the fixing pin 471.

  According to the fixing means 470, the fixing pin 471 has the first base end side locking claw 473 in the accommodation hole 404 of the first inserted member 401 in a state where the substrate box 102 and the movable base portion 203 are fixed. And is hidden from the outside. Further, in this state, the second proximal end side locking claw 474 is engaged in the engagement hole 485 of the second inserted member 481 and is covered and hidden from the outside.

  Therefore, for example, even if a release operation for releasing the locking to the first inserted member 410 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 471, the second insertion member 481 is moved to the second inserted member 481. The locking of the first base end side locking claw 473 and the second base end side locking claw 474 cannot be released, and unauthorized fixing of the fixing pin 471 can be prevented. In particular, since the first base end side locking claws 473 and the second base end side locking claws 474 are provided apart from each other in the axial direction, unauthorized removal can be made more difficult. .

  On the other hand, when the second inserted member 481 is separated from the board box 102 and the locking of the front end side claw 304 to the first inserted member 401 is released, the fixing pin 471 is taken out from the main board unit 100. The first base end side claw 473 of the fixing pin 471 is exposed from the second inserted member 481. Therefore, the pair of first base end side locking claws 473 are urged in the direction approaching each other to be elastically deformed, and the first base end side locking claws 473 and the second base end side engagement with respect to the second inserted member 481. The catch of the pawl 474 can be removed. Then, the second inserted member 481 can be detached from the fixing pin 471 by urging the fixing pin 471 as it is. Therefore, when the base box 102 and the movable base portion 203 are properly fixed, the fixing pin 471 can be easily removed without being damaged or damaged.

(Seventh embodiment)

The outer diameter is almost the same as the maximum separation distance of 305.

  A second insertion hole 493 is provided at the center of the second inserted member 491. The second insertion hole 493 is slightly larger than the outer diameter of the thick shaft portion 302a so that a slight gap can be formed between the outer periphery of the thick shaft portion 302a when the thick shaft portion 302a of the fixing pin 301 is inserted. And it has an internal diameter smaller than the largest separation distance of a pair of base end side latching claw 305. FIG.

  A through hole 495 is provided in the middle position in the axial direction of the second inserted member 491 so as to penetrate in a direction orthogonal to the axial direction. The through-hole 495 extends in the left-right direction of the substrate box 102 so that the base-side locking claw 305 is engaged when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 493. The proximal end side claw 305 has a size substantially the same as or slightly longer than the axial length. When the thick shaft portion 302 a of the fixing pin 301 is inserted into the second insertion hole 493, the base end side locking claw 305 is engaged, and the fixing pin is fixed to the step surface 305 a of the base end side locking claw 305. The inner wall surface 495a of the through-hole 495 can be made to face the removal direction side of 301, and when the fixing pin 301 is urged toward the removal direction, it penetrates the step surface 305a of the proximal end side locking claw 305. The movement of the fixing pin 301 in the removal direction is restricted by contacting the inner wall surface 495a of the hole 495, and the fixing pin 301 can be locked.

  A diameter-enlarged portion 494 is formed at the front position in the axial direction of the second insertion hole 493. The diameter-expanded portion 494 is formed to have a diameter increased between the second insertion hole 493 and the front-side step surface 494a, and is open to the front end surface 491a of the second inserted member 491.

  The diameter-enlarged portion 494 is formed when the thick shaft portion 302a of the fixing pin 301 is inserted into the second insertion hole 493 and the proximal end side locking claw 305 is locked to the second inserted member 491. In order to be accommodated, it has an inner diameter that is slightly larger than the outer diameter of the flange 303 and an axial length that is the same as or slightly longer than the axial length of the flange 303.

  Therefore, when the thick shaft portion 302 a of the fixing pin 301 is inserted into the second insertion hole 493, the step surface 305 a of the proximal end side locking claw 305 can be disposed to face the step surface 495 a of the through hole 495. it can.

  Then, when the fixing pin 301 is urged toward the removal direction, the stepped surface 305a of the base end side locking claw 305 is brought into contact with the stepped surface 495a of the through hole 495 of the second inserted member 491, The fixing pin 301 can be locked by restricting the movement of the fixing pin 301 in the removal direction.

  In addition, the collar portion 303 is accommodated in the enlarged diameter portion 494 and abuts against the step surface 494a, so that the fixing pin 301 can be restricted from moving further in the insertion direction and can be positioned at a predetermined insertion position.

  In the drawing, reference numeral 496 denotes a cover member that covers the through hole 495. The cover member 496 is provided in the square hole portion 123 of the back case body 120, and is spaced apart from the second inserted member 491 in the axial direction of the through hole 495 and faces both end portions of the through hole 495. ing.

  The cover member 496 extends along the second inserted member 491, and the rear end portion located on the rear side in the axial direction of the second inserted member 491 is flush with the rear end surface 491a of the second inserted member 491. It is formed to be positioned.

  When the fixing pin 301 is removed from the second inserted member 491, the gate portion 331 is cut to separate the second inserted member 491 from the second member and expose both end portions of the through hole 495. Then, the base end side locking claws 305 locked in the through holes 495 of the second inserted member 491 are urged in an approaching direction to be elastically deformed, and the pair of base end side locking claws 305 are The maximum separation distance is narrowed to a position smaller than the inner diameter of the second insertion hole 493, the opposing of the inner wall surface 495a of the through hole 495 and the stepped surface 305a of the proximal end side locking claw 305 is released, and the proximal side locking is performed. The claw 305 is released from the second insertion member 491. Then, by moving the fixing pin 301 in the axial direction and the direction of relative removal with respect to the second inserted member 491 and passing the proximal end side locking claw 305 through the second insertion hole 493, The fixing pin 301 can be removed from the second inserted member 491.

  Next, a method of using the fixing means 490 and an operation effect will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 490, the substrate box 102 is slid and attached to the movable base portion 203. Then, the fixing pin 301 is inserted into the second insertion hole 493 of the second inserted member 491 from the front of the substrate box 102.

  When the distal end side portion of the fixing pin 301 is inserted into the second insertion hole 493 of the second inserted member 491, the inclined surface 305 b of the proximal end side locking claw 305 becomes the second insertion hole 493. The state is in contact with the front end in the axial direction.

  From this state, by further pressing the fixing pin 301, the proximal end side locking claws 305 are urged in a direction approaching each other. When the pair of base end side locking claws 305 are elastically deformed to a position where the maximum separation distance is smaller than the inner diameter of the second insertion hole 493, the second insertion hole 493 enters the second insertion hole 493 toward the rear side in the axial direction. Moving. When the proximal-side latching claw 305 moves to the rear side in the axial direction from the inner wall surface 495a of the through-hole 495, the urging force by the second insertion hole 493 is released and restored to return to its original state. The step surface 305 a of the locking claw 305 is disposed at a position facing the inner wall surface 495 a of the through hole 495.

  In addition, by pushing the fixing pin 301 described above, the pair of distal end side locking claws 304 is urged in a direction in which the inclined surface 304 b comes into contact with the front end portion in the axial direction of the first insertion hole 403 and approaches each other. When the maximum distance between the pair of front end side locking claws 304 is elastically deformed to a position smaller than the inner diameter of the first insertion hole 403, the first insertion hole 403 enters and passes through the rear surface of the bottom plate portion 261. Projects axially rearward of 261a. When the pair of distal end side locking claws 304 pass through the first insertion hole 403 and protrude rearward in the axial direction from the rear surface 261a of the bottom plate portion 261, the biasing force by the first insertion hole 403 is released and restored. Then, the deflection returns to the original, and the stepped surface 304b of the front end side locking claw 304 is disposed at a position facing the rear surface 261a of the bottom plate portion 261.

  At such a position, the flange portion 303 of the fixing pin 301 is inserted into the second insertion hole 493, and the bottom surface of the flange portion 303 is disposed at a position substantially flush with the front end surface of the second inserted member 491. . And the collar part 303 contact | abuts to the front side level | step difference surface 334a of the 2nd to-be-inserted member 491, and the movement to the further insertion direction of the fixing pin 301 is controlled.

  When the fixing pin 301 is moved in the removal direction opposite to the insertion direction, the stepped surface 304a of the distal end side claw 304 comes into contact with the rear surface 261a of the bottom plate portion 261, and the proximal end side engagement. The step surface 305a of the pawl 305 comes into contact with the inner wall surface 495a of the through hole 495, and the movement of the fixing pin 301 in the drawing direction is stopped.

  Further, in this state, the base end side locking claw 305 is engaged with the through hole 495, but since both ends of the through hole 495 are covered with the cover member 496, it cannot be touched from the outside. . Therefore, the thin shaft portion 302 b of the fixing pin 301 is inserted into and locked in the first insertion hole 403 of the first inserted member 401, and the thick shaft portion 302 a is inserted into the second insertion hole 493 of the second inserted member 491. Thus, the fixing pin 301 cannot be removed from the first inserted member 401 and the second inserted member 491.

  Accordingly, relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited in a state where the substrate box 102 is coupled to the movable base portion 203, and the substrate box 102 can be detached from the movable base portion 203 and removed. Can be fixed so that it can not.

  In order to release the fixing by the fixing means 490, first, the second inserted member 491 to which the fixing pin 301 is locked is separated from the back case body 120 of the substrate box 102. In order to separate the second inserted member 491 from the back case body 120, the gate portion 331 supporting the second inserted member 491 on the back case body 120 is cut with a tool such as a nipper.

  Next, the fixing pin 301 is removed from the first inserted member 401 and separated. First, the movable base portion 203 is tilted from the standing posture position and positioned and held at the tilted posture position, and the bottom plate portion 261 of the movable base portion 203 is exposed. Then, the pair of front end side locking claws 304 protruding from the first insertion hole 403 to the rear surface 261a side of the bottom plate portion 261 are urged in a direction approaching each other to be elastically deformed.

  Then, the maximum separation distance between the pair of front end side locking claws 304 is narrowed to a position where it is smaller than the inner diameter of the first insertion hole 403, and the rear surface 261 a of the bottom plate portion 261 and the step surface 304 a of the front end side locking claw 304 are opposed. Is released, and the locking of the first insertion member 401 by the front end side locking claw 304 is released. Then, the fixing pin 301 is moved relative to the first inserted member 401 in the axial direction and in a direction in which the fixing pin 301 is relatively removed, and the distal end side locking claw 304 is passed through the first insertion hole 403, thereby fixing the fixing pin 301. Is removed from the first inserted member 401.

  Thereby, the fixing pin 301 is taken out from the board box 102 and the pedestal device 201 with the second inserted member 491 still fitted on the thick shaft portion 302a. Therefore, the board box 102 is released from the base device 201, can be slid in the sliding direction with respect to the movable base 203, and can be detached from the movable base 203.

  When the used fixing pin 301 is reused, an operation of removing the second inserted member 491 from the fixing pin 301 is performed. In order to remove the second inserted member 491 from the fixing pin 301, a pair of proximal end side locking claws 305 protruding from the inner wall surface 495a of the through hole 495 and projecting rearward in the axial direction are attached in a direction approaching each other. It is elastically deformed.

  When the second inserted member 491 is separated from the back case body 120 of the board box 102, both end portions of the through hole 495 are exposed and locked to the inner wall surface 495 a of the through hole 495. The nail 305 is also exposed.

  Accordingly, the maximum separation distance between the pair of base end side locking claws 305 is narrowed to a position where it is smaller than the inner diameter of the second insertion hole 493, and the step surface between the inner peripheral surface 495 a of the through hole 495 and the base end side locking claws 305. The opposing to 305a is cancelled | released and the latching to the 2nd to-be-inserted member 491 by the base end side latching claw 305 is cancelled | released. Then, the fixing pin 301 is moved relative to the second inserted member 491 in the axial direction and in the direction of relative removal, so that the proximal-side locking claw 305 passes through the second insertion hole 493, and the fixing pin 301 is removed from the second inserted member 491.

  Since the pair of distal end side locking claws 304 has a maximum separation distance smaller than the outer diameter of the thick shaft portion 302a, it can be passed through the second insertion hole 493 as it is. Therefore, after the thick shaft portion 302a is removed from the second inserted member 491, the thin shaft portion 302b can be continuously removed. Therefore, the second inserted member 491 can be easily detached from the fixing pin 301 without destroying the fixing pin 301.

  According to the fixing means 490, the fixing pin 301 is engaged with the base end side locking claw 305 in the through hole 495 of the first inserted member 401 in a state where the substrate box 102 and the movable base portion 203 are fixed. The cover member 496 is inserted and hidden from the outside.

  Therefore, for example, even if a release operation for releasing the locking to the first inserted member 410 is performed while the substrate box 102 and the movable base portion 203 are fixed by the fixing pin 301, the base with respect to the second inserted member 491 is performed. The locking of the end side locking claw 305 and the base end side locking claw 305 cannot be released, and unauthorized removal of the fixing pin 301 can be prevented. In particular, the base end side locking claw 305 is locked to the through hole 495 provided at the intermediate position in the axial direction of the second inserted member 491, and both end portions of the through hole 495 are covered with the cover member 496. Thus, unauthorized removal can be made more difficult.

  On the other hand, when the second inserted member 491 is separated from the board box 102 and the locking of the front end side claw 304 to the first inserted member 401 is released, the fixing pin 301 is taken out from the main board unit 100. Both ends of the through hole 495 of the second inserted member 491 are exposed, and the proximal end side locking claw 305 engaged with the through hole 495 is also exposed.

  Therefore, the pair of base end side locking claws 305 can be urged in the direction of approaching each other to be elastically deformed, and the hook of the base side locking claws 305 with respect to the second inserted member 491 can be removed. Then, the second inserted member 491 can be detached from the fixing pin 301 by urging the fixing pin 301 as it is. Therefore, when the base box 102 and the movable base portion 203 are properly fixed, the fixing pin 301 can be easily removed without being damaged or damaged.

  The configuration of the fixing pin 301 described above can be variously modified without departing from the spirit of the present invention. 32 to 34 are diagrams showing other specific examples of the fixing pin.

  32 to 34, a distal end side locking claw 504 and a proximal side locking claw 505 are provided on the shaft portion 502 independently of each other. The base-end-side locking claw 505 has a configuration that does not bend even if it is bent inward in the radial direction of the shaft portion 502.

  A fixing pin 501 shown in FIG. 32 has a round bar-shaped shaft portion 502. The shaft portion 502 has a cylindrical shape with a predetermined thickness, and a disc-shaped flange portion 503 having a diameter increased through a step is provided at the proximal end of the shaft portion 502.

  The shaft portion 502 is provided with a distal end side locking claw 504 and a proximal end side locking claw 505 at the distal end side portion and the proximal end side portion of the shaft portion 502, respectively. A pair of distal end side locking claws 504 and proximal end side locking claws 505 are provided. The distal end side locking claws 504 are provided at positions separated from each other at the distal end side portion of the shaft portion 502, and the proximal end side locking claws 505 are separated from each other at the proximal end side portion of the shaft portion 502. Is provided.

  The distal end side claw 504 extends from the distal end of the shaft portion 502 along the axial direction of the shaft portion 502 and protrudes radially outward from the distal end of the arm portion 504a. A claw portion 504b is provided.

  The arm portion 504 a has a thickness substantially the same as the thickness of the shaft portion 502 and is formed to extend along the axial direction, and is urged toward the radially inner side of the shaft portion 502. The claw portion 504b is moved inward in the radial direction of the shaft portion 502, and is restored by the disappearance of the urging force so that the claw portion 504b can be returned to the original position. .

  The claw portion 504 b has an inclined surface 504 c that is inclined so as to gradually move outward in the radial direction of the shaft portion 502 as it moves toward the proximal end side of the shaft portion 502. Is inserted into the first insertion hole 313 of the first inserted member 310 to abut against the inner peripheral surface of the first insertion hole 313 to urge the arm portion 504a toward the radially inner side of the shaft portion 502. It can be elastically deformed.

  The claw portion 504b has a step surface 504d formed in a step shape so as to be substantially perpendicular to the arm portion 504a between the arm portion 504a and the step surface 504d. The insertion member 310 can face the rear end surface 310a.

  The proximal end side latching claw 505 is an arm that extends from the proximal end side of the shaft portion 502 toward the distal end side along the axial direction of the shaft portion 502 in the window hole portion 502 a formed in the shaft portion 502. Part 505a and a claw part 505b protruding from the arm part 505a to the outside in the radial direction from the shaft part 502.

  The arm portion 505a is elastically deformed by being urged radially inward of the shaft portion 502, moves the claw portion 505b toward the radially inner side of the shaft portion 502, and is restored by disappearance of the urging force. Thus, the claw portion 505b can be returned to the original position.

  The claw portion 505 b has an inclined surface 505 c that is inclined so as to gradually move outward in the radial direction of the shaft portion 502 as it moves toward the proximal end side of the shaft portion 502. When the portion is inserted into the second insertion hole 333 of the second inserted member 330, the arm portion 505 a is urged toward the radially inner side of the shaft portion 502 by abutting against the inner peripheral surface of the second insertion hole 333. So that it can be elastically deformed.

  Further, the claw portion 505b has a step surface 505d formed in a step shape so as to be substantially perpendicular to the arm portion 505a between the claw portion 505b and the step surface 505d. The insertion member 330 can be made to face the rear end surface 330a.

  The distal end side locking claws 504 and the proximal end side locking claws 505 are positioned at a phase angle of 90 degrees between the direction in which the distal end side locking claws 504 are separated from each other and the direction in which the proximal end side locking claws 505 are separated from each other. Have a relationship. The claw portion 504b of the distal end side locking claw 504 and the claw portion 505b of the proximal end side locking claw 505 have substantially the same radial height.

  In order to fix the board box 102 to the base device 201 using the fixing pin 501 having the above configuration instead of the fixing pin 301 in the first embodiment, the second insertion of the second inserted member 330 from the front of the board box 102 is performed. When inserted into the hole 333, the proximal locking claw 505 is locked to the second inserted member 330, and the distal locking claw 504 is locked to the first inserted member 310, so that the fixing pin 501 can be removed. Movement in the direction of departure is restricted. And the collar part 503 is inserted in the enlarged diameter part 334 of the 2nd to-be-inserted member 330, and the movement to the insertion direction of the fixing pin 501 is controlled.

  Therefore, the fixing pin 501 can be in a state where it cannot be removed from the first inserted member 310 and the second inserted member 330. Accordingly, in the same manner as the fixed pin 301, in a state where the substrate box 102 is coupled to the movable base portion 203, the relative sliding movement of the substrate box 102 with respect to the movable base portion 203 is prohibited, and the substrate box 102 is moved to the movable base portion 203. It can be fixed so that it cannot be separated and removed.

  When releasing the fixation of the substrate box 102, the gate portion 331 is cut to separate the second inserted member 330 from the back case body 120 of the substrate box 102, and then from the bottom plate portion 261 of the movable base portion 203. The hook of the protruding claw portion 315b is removed, and the first inserted member 310 is separated from the movable base portion 203.

  As a result, the fixing pin 501 is connected to the movable base portion 203 in the state where the proximal end portion is locked to the second inserted member 330 and the distal end portion is locked to the first inserted member 310. The case body 120 is taken out. Therefore, the fixing of the substrate box 102 to the pedestal device 201 is released, and the substrate box 102 can be slid in the sliding direction with respect to the movable base 203, and the substrate box 102 can be removed from the movable base 203. it can.

  To remove the first inserted member 310 from the fixing pin 501 in order to reuse the used fixing pin 501, the claw portion of the front end side locking claw 504 protruding from the rear end surface 310 a of the first inserted member 310. The 504b is biased in the direction of approaching each other, the opposing of the stepped surface 504d of the front end side locking claw 504 and the rear end surface 310a of the first inserted member 310 is released, and the urging is performed in the direction of pulling out the fixing pin 501 as it is. To do. As a result, the distal end side locking claws 504 can be passed through the first insertion hole 313 while being bent in a direction approaching each other, and the first inserted member 310 can be removed from the fixing pin 501.

  When the first inserted member 310 is removed from the fixing pin 501, the proximal end side locking claw 505 is exposed. Therefore, in order to remove the second inserted member 330 from the fixing pin 501, the claw portions 505 b of the proximal end side locking claws 505 protruding from the rear end surface 330 a of the second inserted member 330 are urged toward each other. Then, the hook to the second inserted member 330 is removed, and the fixing pin 501 is urged as it is. Thereby, the inside of the 2nd insertion hole 333 can be passed in the state which bent the base end side latching claw 505 in the direction which approaches mutually.

  Since the distal end side locking claws 504 and the proximal end side locking claws 505 of the fixing pin 501 protrude outward in the radial direction from the shaft portion 502, the proximal end side locking claws 505 are the second inserted member 330. Then, the stepped surface 504d of the front end side locking claw 504 comes into contact with the rear end surface 330a of the second inserted member 330 and is caught.

  Therefore, the claw portions 504b of the front end side claw 504 protruding from the rear end surface 330a of the second inserted member 330 are urged in a direction approaching each other, and the hook to the second inserted member 330 is removed and left as it is. The fixing pin 501 is biased in the pulling direction. Thereby, the inside of the 2nd insertion hole 333 can be passed in the state where the front end side claw 504 was bent in the direction which approaches mutually.

  Therefore, the fixing pin 501 can be removed from the second inserted member 330, and can be easily removed from the second inserted member 330 without destroying the fixing pin 501.

  A fixing pin 511 shown in FIG. 33 is a modification of the fixing pin 501 shown in FIG. The fixing pins 511 have a positional relationship in which the distal end side locking claws 504 and the proximal end side locking claws 505 have a phase angle of 0 degrees, and are arranged in a line in the axial direction. The fixing pin 511 having the above configuration also has the same effect as the fixing pin 501 shown in FIG.

  A fixing pin 521 shown in FIG. 34 is another modification of the fixing pin 501 shown in FIG. The fixing pin 521 has a shaft portion 522 that includes a thick shaft portion 522a having a relatively large diameter at the proximal end portion and a thin shaft portion 522b that has a relatively small diameter at the distal end portion. The thick shaft portion 522a has a cylindrical shape that has a constant diameter and extends in the axial direction, and the thin shaft portion 522b has a constant diameter that is reduced in diameter through a step at the tip of the thick shaft portion 522a. And has a cylindrical shape extending in the axial direction.

  The thick shaft portion 522a is provided with a proximal end side locking claw 525, and the thin shaft portion 522b is provided with a distal end side locking claw 524. A pair of each of the proximal end side locking claws 525 and the distal end side locking claws 524 is provided at positions separated from each other in the radial direction of the shaft portion 522.

  The proximal end side claw 525 extends from the proximal end side of the thick shaft portion 522a toward the distal end side along the axial direction of the thick shaft portion 522a within the window hole portion 526 formed in the thick shaft portion 522a. It is provided at the tip of the arm portion 527 to be taken out.

  The arm portion 527 is elastically deformed by being biased toward the radially inner side of the thick shaft portion 522a, and moves the proximal end side locking claw 525 toward the radially inner side of the thick shaft portion 522a. The proximal end side locking claw 525 can be restored to its original position by being restored by the disappearance of the force.

  The proximal end side locking claw 525 protrudes radially outward from the thick shaft portion 522a. In addition, an inclined surface 525b that is inclined so as to gradually move outward in the radial direction from the thick shaft portion 522a as it moves from the distal end side to the proximal end side of the arm portion 527, and a proximal end side of the inclined surface 525b And has a step surface 525a formed in a step shape so as to be substantially perpendicular to the arm portion 527.

  The inclined surface 525b comes into contact with the inner peripheral surface of the second insertion hole 333 when the base end side portion of the fixing pin 521 is inserted into the second insertion hole 333 of the second inserted member 330, and the arm portion 527 is thickened. The shaft portion 522a is formed so as to be elastically deformed by being urged inward in the radial direction.

  The stepped surface 525 a is inserted into the second insertion hole 333 by inserting the base end side portion of the fixing pin 521 and the base end side locking claw 525 protrudes from the second inserted member 330. It is formed so that it can be made to oppose the rear-end surface 330a.

  The distal end side claw 524 is provided at the distal end of the arm portion 528. The arm portion 528 is formed by dividing the thin shaft portion 522b in the radial direction and in a direction orthogonal to the direction in which the pair of proximal end side locking claws 525 are separated from each other.

  The arm portion 528 is elastically deformed by biasing toward the radially inner side of the thin shaft portion 522b, and moves the distal end side locking claw 524 toward the radially inner side of the narrow shaft portion 522b. It has an elastic force that can be restored by disappearance and can return the front-end side locking claw 524 to its original position.

  The distal end side claw 524 protrudes radially outward from the thin shaft portion 522b. The inclined surface 524b is inclined so as to gradually move toward the radially outer side of the thin shaft portion 522b as it moves from the distal end side to the proximal end side of the arm portion 528, and the proximal end side of the inclined surface 524b And has a step surface 524a formed in a step shape so as to be substantially vertical to the arm portion 528.

  The inclined surface 524b comes into contact with the inner peripheral surface of the first insertion hole 313 to narrow the arm portion 528 when the proximal end portion of the fixing pin 521 is inserted into the first insertion hole 313 of the first inserted member 310. The shaft portion 522b is formed so as to be elastically deformed by being urged inward in the radial direction.

  The stepped surface 524a is formed by inserting the proximal end portion of the fixing pin 521 into the first insertion hole 313 and projecting the distal end side locking claws 524 from the first inserted member 310. It is formed so as to be opposed to the rear end surface 310a.

  The front end side claw 524 is formed so as to be located radially inside the outer peripheral surface of the thick shaft portion 522a. In other words, the distal-side locking claw 524 is set such that the radial distance from the axial center of the thin shaft portion 522b to the maximum projecting portion is equal to or smaller than the radius of the thick shaft portion 522a, and the outer periphery of the thick shaft portion 522a. It is formed so as not to protrude outward in the radial direction from the surface.

  In the present embodiment, the maximum separation distance between the pair of distal end side locking claws 524, that is, the separation distance of the most separated portion of the pair of distal end side locking claws 524 is equal to or less than the diameter of the thick shaft portion 522a. It has a size.

  Therefore, when the thin shaft portion 522 b of the fixing pin 521 is moved in the direction of removing from the second insertion hole 333 of the second inserted member 330, the distal end side claw 524 is caught by the second inserted member 330. Without passing through the second insertion hole 333, the distal end portion can be removed from the second insertion hole 333. Therefore, the fixing pin 521 can be easily removed from the second inserted member 330.

  The fixing pin 521 has shown a case where the distal end side locking claw 504 and the proximal side locking claw 505 have a positional relationship of 90 degrees, but any phase angle may be used. The distal end side locking claws 504 and the proximal end side locking claws 505 may have a positional relationship in which the phase angle is 0 degree.

(Eighth embodiment)
Next, an eighth embodiment will be described below with reference to the drawings. In addition, about the component similar to said each embodiment, the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  FIG. 35A is a perspective view of the back case body 120 according to the present embodiment. FIG. 2B is an enlarged view of the main part. What is characteristic in the present embodiment is that the flange 126 provided on the back case body 120 is urged in the direction in which the bottom plate portion 261 of the movable base portion 203 is separated from the back case body 120 toward the rear. That is, the arm portion 503 is provided so as to leave a trace (see FIG. 12 for the configuration relating to the movable base portion 203).

  The flange 126 is an upper end edge of the back case body 120 and a position corresponding to the left slit groove for constituting the locking piece 286 of the movable base portion 203 from the left end portion (right side in the figure) of the back case body 120. Until the position corresponding to the slit groove on the right side for forming the locking piece 286 of the movable base portion 203 from the vicinity where the screw hole 128 (see FIG. 14) of the right end portion of the back case body 120 is formed. Two portions are formed to protrude rearward from the back case body 120. In particular, at the upper position of the second inserted member 330, the protruding amount protruding rearward is configured to be approximately the same as the rearward extending amount of the second mounting surface portion 223 of the fixed base portion 202. Therefore, when the flange 126 is viewed in plan, a stepped portion is seen at a midpoint due to a difference in the protrusion amount of the flange 126. A portion having a large protruding amount is defined as a bulging portion 501. When the back case body 120 and the front case body 110 are combined with each other and mounted on the movable base portion 203, the stepped portion is close to the flange piece 222 of the fixed base portion 202, and the upper surface of the flange 126 is the front case body. 110 is configured to be flush with the upper surface of 110.

  Similarly, as can be understood from FIG. 35, at the end of the bulging portion 501 near the center of the back case body 120, the curl prevention wall 502 has the same protruding amount as the protruding amount of the bulging portion 501. It is formed so as to extend a predetermined length downward. The length is substantially equal to the length of the slit groove notched downward from the upper end edge of the bottom plate portion 261 of the movable base portion 203 described above. When the substrate box 102 is mounted on the movable base portion 203, the turn prevention wall 502 has a shape that enters the slit groove of the movable base portion 203.

  An arm portion 503 having a fragile portion 503 a is formed at an end portion of the bulging portion 501 near the side end of the back case body 120 so as to extend a predetermined length below the back case body 120. The length is substantially the same as the length of the sag prevention wall 502. Further, a predetermined interval, that is, an interval substantially the same as the thickness of the bottom plate portion 261 of the movable base portion 203 is provided between the arm portion 503 and the back surface of the bottom plate portion 121 of the back case body 120. When 102 is mounted on the movable base portion 203, the bottom plate portion 261 of the movable base portion 203 is configured to fit in the gap without any gap. Further, the fragile portion 503 a is formed by providing a notch at the base portion of the arm portion 503. When viewed from the front, the arm portion 503 is provided at a position that does not overlap the second inserted portion 330 and the gate portion 331, and the arm portion 503 is visible from the front in a state where the board box 102 is mounted on the base device 201. be able to.

  Note that the above-described locking piece 286 is located between the bulging portions 501, and the operation of mounting and removing the substrate box 102 on the above-described movable base portion 203 is performed at that position. In addition, a locking hole 127 is formed at a position closer to the front of the upper surface of the bulging portion 501. In the present embodiment, two are provided for each flange 126, and are arranged in the vicinity of each second inserted member 330. A locking portion 288 protruding from the movable base portion 203 is fitted into the locking hole 127. The locking portion 288 protrudes upward from the bottom plate portion 261 of the movable base 203. Then, the locking portion 288 enters the locking hole 127 from below the flange 126 with the substrate box 102 attached to the movable base portion 203, penetrates through the locking hole 127, and the tip is above the flange 126. Has a protruding shape.

  Therefore, when the board box 102 is mounted on the movable base portion 203 and the bottom plate portion 261 of the movable base portion 203 is urged away from the back case body 120 in the rearward direction, the locking portion 288 is locked. Since it is inserted into the hole 127, a gap is prevented from being generated between the bottom plate portion 261 and the back case body 120. However, when further force is applied and the locking portion 288 is removed from the locking hole 127 and moved in a direction to separate the bottom plate portion 261 of the movable base portion 203 rearward with respect to the back case body 120, Since the arm portion 503 is in close contact with the bottom plate portion 261 of the movable portion base portion 203, the arm portion 503 is broken at the weak portion 503a, and the trace remains. Even if the arm portion 503 does not break, a phenomenon such as bending or whitening occurs in the vicinity of the fragile portion 503a of the arm portion 503, and the bottom plate portion 261 of the movable base portion 203 is separated backward from the back case body 120. There remains a trace energized in the direction. As described above, in order to make it possible to confirm the inside of the substrate box 102 from the outside of the substrate box 102, the movable base portion 203 and the movable base portion 203 are made of a movable base relative to the back case body 120 while using a transparent resin material. An arm portion 503 is provided as means for leaving a trace moved in a direction in which the bottom plate portion 261 of the portion 203 is moved backward.

  Note that when the substrate box 102 is mounted on the movable base portion 203, an excessive force is not applied to the arm portion 503, so that the substrate box 102 is not destroyed at the time of mounting. Here, the arm portion 503 can be provided not on the back case body 120 but on the front case body 110 or the movable base portion 203. However, when the arm portion 503 is provided on the movable base portion 203, the arm portion 503 is moved to the movable base portion 203 of the substrate box 102. It is necessary to install it in a part where it will not be an obstacle to wearing. For example, an arm portion protruding from the front end portion of the side plate portion 264 toward the substrate box 102 side can be provided. Since the arm portion 503 is provided at a position where the substrate box 102 can be viewed from the front in a state where the board box 102 is mounted on the pedestal device 201, the arm portion 503 can be viewed without rotating the movable base portion 203, and a trace of fraudulent acts has been performed. Can be confirmed quickly.

  Further, when the board box 102 is attached to the movable base portion 203, the bulging portion 501 of the flange 126 is positioned above the portion from the first inserted member 310 to the second inserted member 330, and the back case body 120. And the bottom plate portion 261 of the movable base portion 203 can be covered from above the substrate box 102. In addition, the wrinkle prevention wall 502 is connected to the bulging portion 501 in a substantially L shape to increase the strength, and the wrinkle prevention wall 502 is configured to cover the slit groove of the movable base portion 203 without gaps. Unauthorized operations such as cutting the fixing pin 301 by inserting a cutter or a saw blade between the back case body 120 and the bottom plate portion 261 can be prevented.

  Therefore, in comparison with the first to seventh embodiments described above, traces that are biased in the direction in which the bottom plate portion 261 of the movable base portion 203 is separated rearward with respect to the back case body 120 are reliably left, and the back surface. Unauthorized operations such as cutting the fixing pin 301 by inserting a cutter or a saw blade between the case body 120 and the bottom plate portion 261 can be prevented more reliably.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in each of the above-described embodiments, the pedestal device 201 is described as the first member, and the substrate box 102 is described as the second member. However, the present invention is not limited to this. For example, the front case body 110 and the back case body 120 constituting the board box 102 may be a first member and a second member, respectively, as long as they are two members that are coupled and separated by sliding relative to each other.
