Description

The present invention provides a regulating (fixing) means for fixing the first member and the second member to each other by a regulating (fixing) member, for example, a main control device (second member) held by a pedestal device (first member) within the housing ) To the pedestal device so that it cannot be removed from the pedestal device, or inside the control board formed by joining the front case body (first member) and the back case body (second member) together The present invention relates to a gaming machine such as a slot machine provided with a fixing means for fixing a board box that can be accommodated to each other so that it cannot be separated into a front case body and a back case body.

  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.

  Since the maintenance and management work of the control board is required, the board box is detachably held in the housing via the pedestal device so that it can be removed from the pedestal device as needed during work. It has become.

  For example, as shown in Patent Document 1, the pedestal device holds a substrate box when the substrate box is slid to one side in the sliding direction, and removes the substrate box when slid to the other side in the sliding direction. It has the structure which can do. Then, the pedestal device holds the substrate box so that it can be rotated in the housing so that the control substrate can be viewed from both the front side and the back side and whether or not the control substrate has been tampered with can be confirmed from the appearance. It has a configuration. In the base device, the board box extends in parallel along the back plate in the housing, and from the housing position where the front side of the control board is visible, the other side from the back board with the one side of the board box as an axis It can be made to rotate to the rotation position which is the position which can be separated and can visually recognize the back side of a control board.

  The board box is made of a transparent resin material so that the control board can be seen. In order to prevent the control board from being illegally removed from the pedestal device and taken out of the housing, to be replaced with an illegal control board, or to be tampered with the control board, the pedestal is secured by a fixing means. It is fixed to the device.

  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 side part of the fixing pin, the front end side part of the fixing pin is locked to the pedestal device by the insertion of the fixing pin. In such a locked state, when the pedestal device places the substrate box in the accommodation position, the substrate box and the back plate of the housing are opposed to each other, and the tip side portion of the fixing pin is hidden from the outside. However, when the pedestal device places the substrate box in the rotating position, the back side of the substrate box is exposed, and the locking claw can be released.

  In this way, when a 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 There is a risk of unauthorized removal from the pedestal device.

  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 inserted members in advance so that the fixation and release of the substrate box and the pedestal device can be repeated 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-mentioned application-fixed fixing pin, the base end side locking claw of the fixing pin is covered and concealed from the outside by the pedestal device while being locked to the board box. It is not possible to perform a release operation to release the lock by directly touching from the outside. Accordingly, unless at least one of the inserted member of the board box, the inserted member 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 the fixing pin repeatedly, there is a problem that if the fixing pin is destroyed, the fixing pin cannot be reused. Moreover, there is a possibility that even the fixed pin may be destroyed when the member to be inserted is broken, and the work of taking out the fixed pin without breaking it is complicated.

  Also, in the case of a method of preparing a plurality of fixing pins in advance and using them one after another, for example, after breaking the fixing pins and releasing the fixing, the unused fixing pins are replaced with the same inserted member again. If the board box and the pedestal device are not yet fixed, there is a risk that a fraudulent act of disguise will be performed.

  In the case of a plurality of fixing pins, when releasing the fixation between the substrate box and the pedestal device, the inserted member of the substrate box and the inserted member of the pedestal device are inserted into the substrate box and the pedestal while the fixing pin is locked. Disconnected from each device. Then, the fixing pin and the member to be inserted are removed in a state where the fixing pin is locked to the member to be inserted, and discarded as a waste material.

  Therefore, when the material of the inserted member is different from that of the fixed pin, for example, the board box is made of plastic and the fixed pin is made of metal, and when it is separated and discarded or recycled as resource waste, each inserted member from the fixed pin It is necessary to remove and separate.

  However, the operation of removing and separating each inserted member from the fixing pin is complicated, resulting in high costs. Therefore, there is a problem that it is difficult to separate and discard such waste materials and to recycle them 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 structure in which a restricting (fixing) member for fixing the first member and the second member can be easily taken out in a reusable state. It is to provide a gaming machine having.

Then, by separating the first inserted member from the first member, the fixing member can be rotated integrally with the first inserted member, and the fixing member is rotated relative to the second inserted member. be able to. Therefore, the proximal end side locking claw can be disposed at the rotation release position with respect to the second inserted member, and the locking to the second inserted member by the proximal side locking claw can be released.

Then, it is possible to release the first insertion member from the fixing member by releasing the engagement of the distal end side claw with respect to the first insertion member, withdrawing the distal end portion of the fixing member from the first insertion hole. Therefore, the fixing member can be moved relative to the second inserted member, the proximal end portion of the fixing member can be removed from the second insertion hole, and the second inserted member can be removed from the fixing member. Therefore, the fixing of the first member and the second member can be released, and the first member and the second member can be relatively slid and separated.

Means 8. In any one of the means 4 to 6, the first inserted member is opposed to the distal direction locking claw when the distal end portion of the stationary member is inserted into the first insertion hole. And a first locking portion that restricts the movement of the fixing member relative to the first insertion member in the removal direction, and a distal-side locking claw locked to the first locking portion. And a first rotation restricting portion that is disposed opposite to one side of the fixing member in the rotation direction and restricts the rotation of the fixing member relative to the first insertion member in the one direction of rotation. The insertion member is arranged to face the other side in the rotation direction of the fixing member with respect to the proximal-side locking claw locked to the second locking portion, and the relative rotation of the fixing member with respect to the second inserted member A game machine comprising: a second rotation restricting portion that restricts rotation in the other direction.

In addition, the second rotation restricting portion faces the other end in the rotation direction of the fixing member with respect to the base end side claw, and the rotation of the fixing member in the rotation direction on the other side with respect to the second inserted member is restricted.

Therefore, the proximal end side locking claw cannot be moved from the rotation locking position to the rotation release position, and the state locked to the second inserted member is maintained. Therefore, the movement of the fixing member relative to the first inserted member and the second inserted member in the relative removal direction can be restricted, and the removal of the fixing member from the first member and the second member can be prevented. And the relative sliding movement of a 1st member and a 2nd member is prohibited, and a 1st member and a 2nd member can be maintained in the state mutually fixed.

On the other hand, when releasing fixation of the first member and the second member, at least one of the first inserted member and the second inserted member is separated. Thereby, relative rotation of the fixing member with respect to the second inserted member is allowed, and the proximal end side locking claw is disposed at the rotation release position with respect to the second inserted member, and the proximal side side locking claw is used. The locking to the second inserted member can be released.

And the latching of the front end side latching claw with respect to the 1st inserted member is cancelled | released, the front end side part of a fixing member is extracted from a 1st insertion hole, and a 1st inserted member is removed from a fixing member. Then, the fixing member is moved relative to the second inserted member, the proximal end portion of the fixing member is removed from the second insertion hole, and the second inserted member can be removed from the fixing member.

Therefore, the fixing of the first member and the second member can be released, and the first member and the second member can be relatively slid and separated. As described above, since the locking to the second inserted member by the base end side locking claw can be released without directly touching the base end side locking claw, the reusable state can be obtained without destroying the fixing member. Can be removed.

Means 9. In the means 8, the first inserted member is provided on the other side in the rotation direction of the fixing member with respect to the first locking portion, and the fixing member with the distal end side locking claw locked to the first locking portion is the first locking member. When the first insertion member is rotated relative to the other side in the rotation direction, the fixing member is disposed on the removal direction side of the fixing member with respect to the proximal-side locking claw. First passage portion that allows the distal end side locking claw to pass therethrough and allows the fixing member to move relative to the first inserted member in the removal direction when the urging force is relatively biased toward the removal direction. A gaming machine characterized by comprising:

The means 9 shows an example of a specific configuration of the first inserted member. According to this, the first inserted member has a first passage portion. And when the fixing member with which the front end side latching claw was latched by the 1st latching part was rotated relatively to the rotation direction other side with respect to the 1st to-be-inserted member, with respect to a base end side latching claw And when the fixing member is urged relative to the first insertion member from the position toward the removal direction, the distal end side locking claw is passed through the first insertion member. 1 It has the structure which accept | permits the movement to the removal direction of the fixing member relative to the member to be inserted.

Therefore, by rotating the fixing member with the distal end side locking claw locked to the first locking portion relative to the first insertion member toward the other side in the rotational direction, the proximal side locking claw On the other hand, a 1st channel | path part can be arrange | positioned at the removal direction side of a fixing member. Then, by urging the fixing member relative to the first inserted member in such a state from the above state, the locking of the distal end side claw with respect to the first inserted member is released, and the fixing member Movement in the removal direction can be allowed.

Therefore, when the first inserted member is removed from the fixing member, the distal end side locking claw with respect to the first locking portion only needs to be rotated relative to the first inserted member in the rotational direction to the other side. The locking can be released, and the first inserted member can be easily removed from the fixing member.

And a locking hole 287. Then, when the main control device 101 is mounted on the movable base 203, the protrusion 121a (see FIG. 10) protruding from the board box 102 is engaged with the engagement hole 287 of the engagement portion 285, While the board box 102 is locked to the movable base 203, the locking of the board box 102 to the movable base 203 is released by elastically deforming the locking piece 286 to release the locking to the locking hole 287. It can be done.

  The first inserted member 310 constitutes a fixing means 300 that fixes the main control device 101 to the movable base portion 203 in cooperation with a fixing pin 301 and a second inserted member 330 described later. A plurality (four in this embodiment) are provided on the left and right sides of 285 so as to be arranged in a horizontal row. The first inserted member 310 has a configuration that protrudes rearward from the bottom plate portion 261. When the movable base portion 203 is in the standing posture position, as shown in FIG. 10, the cutout portion 221 of the fixed base portion 202 is provided. 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. Can be supported.

  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.

  Then, axial support plate portions 243 and 244 of the fixed base portion 202 made of a metal material are disposed at the left and right end portions of the rotation shaft portion 265 in the axial direction, and the base end of the support pin 207 is disposed. 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, the tip of a tool such as a bar or a screwdriver is prevented 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 act of destroying the rotating shaft portion 265 such as using a tool to pry.

  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 the main substrate 103 is prevented 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. A mounting screw is inserted into the bottom hole portion 214a, and the third position is set through the window holes 274a and 261a of the movable base portion 203 and the opening hole 211a of the bottom plate portion 211 in a state where the movable base portion 203 is positioned and held in the standing posture position. A mounting screw is inserted through the bottom hole 225a of the mounting surface portion 225, and is fixed to the back plate 2c by being screwed into a nut portion (not shown) provided in advance in each corresponding position inside the back plate 2c. Is done. The mounting screw engages with a tool tip such as a screwdriver inserted into the housing from the front side of the housing 2 and rotates the tool in a state where the rotation center axis extends in the front-rear direction of the housing 2. Screwed.

  Also, a screw (not shown) is inserted from the back of the housing 2 into an insertion hole (not shown) formed in the back plate 2c of the housing 2 in advance, and the screw tip portion is connected to the housing from the back plate 2c. 2 and is screwed into a screw hole 223a provided in the second mounting surface portion 223 on the back surface of 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.

  Next, the configuration of the main controller 101 will be described below with reference to FIG.

The step portion 112 is formed with a plurality of socket insertion holes 112a through which the socket 104 on the main board 103 is inserted.

  A plurality of long holes 113 are provided at the left end and the right end of the front case body 110 so as to be lined up and down at predetermined intervals. In the upper part of the front case body 110, a horizontally-long rectangular hole portion 114 is formed, and the sealing member 142 of the disassembly seal portion 141 is provided in the square hole portion 114 at positions separated from each other on the left and right. ing. The sealing member 142 is a cylindrical body having an inner diameter into which the sealing pin 130 can be inserted, and is connected to the front case body 110 by a gate portion 116 that extends vertically in the square hole portion 114. The gate portion 116 can be cut with a tool such as a nipper, and the sealing member 142 can be cut off from the front case body 110 by cutting.

  A fixed surface 117 is formed on the lower right side of the front case body 110, and a screw hole 117a for fixing the substrate box to the movable base 203 is screwed.

  The fixed surface 117 extends along the reciprocating direction of the substrate box 102 on the front side of the front case body 110, and the back surface of the fixing flange 284 of the movable base portion 203 by holding the substrate box 102 to the movable base portion 203. Has a planar shape that faces and overlaps.

  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.

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.

  In addition, since 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, a tool such as a screwdriver can be used for a right-handed operator. It is easy to turn and can be fixed easily.

  And since the front door 3 is supported by the left end part of the housing | casing 2, by opening the front door 3, the left end part side of the housing | casing 2 which is the side facing 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.

By sliding relative to the upper side which is one side in the 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 coupled to each other to form the 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 separated 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 fastened by screws 132 and 133 in a state where the front case body 110 and the back case body 120 are coupled to each other to form the substrate box 102, and relative vertical movement is restricted.

  A screw hole 119 is provided on the left side of the upper end portion of the front case body 110. The screw hole 119 is screwed on the back surface side of the front case body 110, and the screw 132 is inserted into a through hole formed in a corresponding portion of the back case body 120, and the screw hole 119 of the front case body 110 is inserted. By screwing, the back case body 120 is fastened to the front case body 110, and relative sliding movement between the front case body 110 and the back case body 120 can be restricted.

  A screw hole 128 is provided on the right side of the upper end of the back case body 120. The screw hole 128 is threaded on the front side of the back case body 120, and the 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 fastened to the back case body 120 by screwing into the screw holes 128.

  Therefore, the attachment of these screws 132 and 133 prevents relative sliding movement between the front case body 110 and the back case body 120, and prevents the board box 120 from being separated into the front case body 110 and the back case body 120. On the other hand, by removing the screws 132 and 133, the front case body 110 and the back case body 120 are allowed to slide relative to each other, and the board box 102 is separated into the front case body 110 and the back case body 120. Can do.

  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 disassembly sealing part 141, the relative vertical movement of the front case body 110 and the back case body 120 is allowed, and the board box 102 is separated into the front case body 110 and the back case body 120. It becomes possible.

  As described above, in order to separate the substrate box 102 into the front case body 110 and the back case body 120 after being sealed by the disassembly sealing portion 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 cutting 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.

  A second inserted member 330 is provided in the square hole portion 123. The second inserted member 330 constitutes a part of a regulating (fixing) member 300 to be described later, and a plurality of the second inserted members 330 are provided so as to be aligned in the left and right rows within the square hole portion 123. Each second inserted member 330 is concentrically continuous with the first inserted member 310 so as to face the first inserted member 310 of the movable base portion 203 in a state where the substrate box 120 is mounted on the movable base portion 203. It is provided in the position to do.

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

  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, the movement of the substrate box 102 in the removal 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. Unfixing of the fixing means 300 is performed by separating the second inserted member 330 from the substrate box 102 and removing the first inserted member 310 from the movable base 203.

  By releasing the fixation of the fixing means 300, the substrate box 102 is allowed to slide relative 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 fixed by the fixing means 300 from the movable base portion 203, 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.

  Then, when the main board 103 is removed from the board box 102 due to a malfunction or inspection of the main control apparatus 101, when the work on the main control apparatus 101 is 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 control device 101 is performed for the second time or later, such as when the main substrate 103 is next removed from the substrate box 102, the fixing by the fixing means 300 is released, and the main control device 101 is removed from the pedestal device 201. be able to.

  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 control device 101 is separated from the placement portion 262 along the bottom plate portion 211 of the movable base portion 203, in other words, orthogonal to the rotation center axis of the rotation shaft portion 265. Then, it is slid in the separating direction and 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.

  Next, the configuration of the above-described fixing means 300 will be described in detail below. 19 is a perspective view of the fixing pin 301, FIG. 20 is a perspective view showing the first inserted member 310, FIG. 21 is a view in the direction of the arrow X in FIG. 20, and FIG. 23 is a diagram for explaining the configuration of the second inserted member 330, FIGS. 24 and 25 are sectional views of the fixing means 300, FIGS. 26 and 27 are exploded views of the fixing means 300, and FIG.

  The arm portion 304 a has a thickness substantially the same as the thickness of the shaft portion 302 and is formed to extend along the axial direction, and is urged toward the radially inner side of the shaft portion 302. The claw portion 304b is moved inward in the radial direction of the shaft portion 302, and is restored by the disappearance of the urging force so that the claw portion 304b can be returned to the original position. .

  The claw portion 304 b has an outer surface that is inclined so as to gradually move to the radially outer side of the shaft portion 302 as it moves toward the proximal end side of the shaft portion 302, and the tip side portion of the fixing pin 301 is When inserting into the first insertion hole 313 of the first inserted member 310, the arm 304 a comes into contact with the inner peripheral surface of the first insertion hole 313 to urge the arm portion 304 a radially inward of the shaft portion 302 to be elastic. It can be deformed.

  Further, the claw portion 304b has a step surface formed in a step shape so as to be substantially vertical to the arm portion 304a, and this step surface is a first engagement of the first inserted member 310 described later. It can be made to oppose the front end surface 316a of the stop part 316.

  The proximal end side locking claw 305 is an arm that extends from the proximal end side of the shaft portion 302 toward the distal end side along the axial direction of the shaft portion 302 in a window hole portion 302 a formed in the shaft portion 302.

  The arm portion 305a is elastically deformed by being biased toward the radially inner side of the shaft portion 302, moves the claw portion 305b toward the radially inner side of the shaft portion 302, and is restored by the disappearance of the biasing force. The claw portion 305b can be returned to the original position.

  The claw portion 305 b has an outer surface that is inclined so as to gradually move toward the radially outer side of the shaft portion 302 as it moves toward the proximal end side of the shaft portion 302. Is inserted into the second insertion hole 333 of the second inserted member 330, abuts against the second locking portion 334 in the second insertion hole 333, and the arm portion 305 a is directed radially inward of the shaft portion 302. It can be energized and elastically deformed.

  The claw portion 305b has a step surface formed in a step shape so as to be substantially perpendicular to the arm portion 305a, and this step surface faces the rear end surface 336 of the second locking portion 334. It can be made to.

  The distal-side locking claws 304 and the proximal-side locking claws 305 are positioned at a phase angle of 90 degrees between the direction in which the distal-side locking claws 304 are separated from each other and the direction in which the proximal-side locking claws 305 are separated from each other. Have a relationship. The claw portion 304b of the distal end side locking claw 304 and the claw portion 305b of the proximal end side locking claw 305 have substantially the same radial height.

  The first inserted member 310 is made of, for example, a synthetic resin material such as polycarbonate having a predetermined rigidity like the fixing pin 301. As shown in FIGS. The first insertion hole 313 formed in the approximate center of the flat plate portion 312 and a pair of holding claws 315 projecting from the back surface of the flat plate portion 312 at the left and right side positions of the flat plate portion 312.

  The flat plate portion 312 has a flat plate shape having substantially the same thickness as the bottom plate portion 261 of the movable base portion 203. The first insertion hole 313 has a round hole shape through which the distal end portion of the fixing pin 301 can be inserted. The inner diameter of the first insertion hole 313 is set to be larger than the maximum separation distance of the pair of arm portions 304a and smaller than the maximum separation distance of the pair of claw portions 304b. When the distal end side portion is inserted, a slight gap is formed between the first insertion hole 313 and the arm portion 304a.

  The holding claw 315 is for detachably holding the first inserted member 310 to the fitting portion 321 of the movable base portion 203, and an arm portion 315a extending substantially vertically from the back surface of the flat plate portion 312; A claw portion 315b that protrudes in a direction away from each other at the tip of the arm portion 315a is provided.

  The arm portion 315a is configured to move 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 to return the claw portion 315b to its 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 (see, for example, FIG. 24).

  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 from the opening hole 321d of the fitting part 321, and can be hooked on the fitting part 321. It is like that.

  Further, the flat plate portion 312 is locked so that the claw portion 304b of the front end side locking claw 304 is hooked so that the fixing pin 301 cannot move in the direction of pulling out from the first inserted member 310 (withdrawal direction). A first restricting portion 316 and a rotation restricting portion 317 that restricts the rotational movement of the fixing pin 301 around the axis while being engaged with the first engaging portion 316 are provided.

  The first locking portion 316 has a cylindrical shape that communicates with the first insertion hole 313 and coaxially projects from the back surface of the flat plate portion 312, and the inner diameter thereof is the same as the inner diameter of the first insertion hole 313. Is set. The distal end surface 316 a of the first locking portion 316 is formed in a planar shape orthogonal to the axial direction of the first locking portion 316, and the distal end portion of the fixing pin 301 is used as the first insertion hole of the flat plate portion 312. When the claw portion 304b of the front end side locking claw 304 is protruded in the axial direction from the front end surface 316a of the first locking portion 316, the insertion portion 313 is inserted into the claw portion 304b of the front end side locking claw 304. It arrange | positions at the removal direction side of the fixing pin 301, and opposes the level | step difference surface of the nail | claw part 304b.

  Accordingly, the distal end portion of the fixing pin 301 is inserted into the first insertion hole 313 of the flat plate portion 312, and the claw portion 304 b of the distal end side locking claw 304 protrudes in the axial direction from the distal end surface 316 a of the first locking portion 316. When it is attempted to move the fixing pin 301 in the removal direction, which is the direction in which the fixing pin 301 is pulled out toward the base end side, the stepped surface of the claw portion 304b of the distal end side locking claw 304 is moved to the first locking portion 316. It is possible to lock the fixing pin 301 by abutting the tip end surface 316a of the lens and restricting movement in the removal direction.

  When the fixing pin 301 is removed from the first inserted member 310, the shaft is more than the distal end surface 316 a of the first locking portion 316 in a state where the first inserted member 310 is removed from the fitting portion 321. The pair of claw portions 304b protruding in the direction is urged toward each other to elastically deform each arm portion 304a, and the claw portions 304b are unlocked. Then, the fixing pin 301 is urged in the removal direction so that the distal end side locking claw 304 passes through the first insertion hole 313, and the fixing pin 301 is removed from the first insertion member 310.

  The rotation restricting portion 317 extends from the distal end of the first locking portion 316 along the axial direction of the first locking portion 316 and is separated from each other in the radial direction of the first locking portion 316 to form a pair. Then, the distal end portion of the fixing pin 301 is inserted into the first insertion hole 313 of the flat plate portion 312, and the claw portion 304 b of the distal end side locking claw 304 protrudes in the axial direction from the distal end of the first locking portion 316. Thus, each of the claw portions 304b has a facing surface 317a that is separated in a direction orthogonal to the direction in which the claw portions 304b are separated from each other and faces the one side in the rotation direction and the other side in the rotation direction.

  The opposing surface 317a restricts the fixed pin 301 from rotating by contacting the distal end side claw 304 when the fixed pin 301 is rotated around the axis in one direction and the other in the rotational direction. Even in a state where the pair of claw portions 304b of the front end side locking claws 304 are urged toward each other and the arm portions 304a are elastically deformed, the rotational direction one side and the rotational direction of the front end side locking claws 304 are also provided. It is configured to face the other side and regulate the rotation of the rotation pin 301.

  In the present embodiment, in the first inserted member 310, each rotation restricting portion 317 is separated in the left-right direction of the movable base portion 203, and each distal end side locking claw 304 is between the rotation restricting portions 317. It is attached to the movable base 203 so as to be positioned at a position separated in the vertical direction.

  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 forming the surface of the flat plate portion 312 of the first inserted member 310 so as not to protrude from the surface of the bottom plate portion 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 FIGS. 24 to 27, the fitting portion 321 is provided in a rectangular recess 321 a into which the flat plate portion 312 is fitted and accommodated, and is provided at a substantially central position of the rectangular recess 321 a, so A round hole 321b into which the first locking part 316 and the rotation restricting part 317 are inserted and accommodated, and a nail hole into which the holding claw 315 is inserted in the rectangular recess 321a and on both the left and right sides of the round hole 321b. Part 321c.

  The rectangular recess 321a has a depth substantially the same as the plate thickness of the flat plate portion 312. The round hole 321b can accommodate the first locking portion 316 and the rotation restricting portion 317 of the first inserted member 310. Has an inner diameter. 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 first locking portion 316 and the rotation restricting portion 317 are inserted into the round hole portion 321b, and the flat plate portion 312 is fitted into the rectangular concave portion 321a. With the surface of 312 flush with the surface of the bottom plate portion 261 of the movable base portion 203, the claw portion 315b of the holding claw 315 is formed at a position protruding from the opening hole 321d.

  Further, the maximum separation distance between the pair of claw hole portions 321 c is formed to be the same as or slightly shorter than the maximum separation distance between the pair of arm portions 315 a of the first inserted member 310.

  Therefore, the arm part 315a of the holding claw 315 can be elastically deformed and inserted into the claw hole part 321c, and the claw part 315b can be protruded from the opening hole 321d, thereby restoring the arm part 315a and hooking the claw part 315b. The first inserted member 310 can be held in a state attached to the fitting portion 321.

  When removing the first inserted member 310 from the fitting portion 321, the pair of claws 315b protruding from the opening hole 321d are urged toward 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 rear 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. 24 and 25, the rectangular recess 321 a and the round hole 321 b are closed on the rear side of the bottom plate portion 261, and the flat plate portion 312 of the first inserted member 310, the first plate is provided from the rear of the bottom plate portion 261. The engaging portion 316 and the rotation restricting portion 317 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. 22, for example. In a state where the substrate box 102 is mounted on the movable base portion 203, the substrate box 102 is disposed at a position communicating with each first inserted member 310 of the movable base portion 203.

  As shown in FIGS. 25 and 27, the second inserted member 330 has a cylindrical shape having a certain thickness, and a second insertion hole 333 into which the fixing pin 301 is inserted is formed at the center thereof. It has been drilled. And it is supported in the square hole part 123 of the back case body 120 by the gate part 331.

  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 central 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 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 each 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. The rear end edge of the gate portion 331 in the width direction and the movable base portion 203 are positioned in front of the rear end surface (front case body 110 side) and the substrate box 102 is held by the movable base portion 203. 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 collar portion 303 of the fixing pin 301 to the distal end of the proximal end side locking claw 305. The second insertion hole 333 is larger than the outer diameter of the flange 303 of the fixing pin 301 and has an inner diameter that allows the flange 303 to be inserted with a predetermined gap.

  A second locking portion 334 and a second passage portion 339 are formed in the second insertion hole 333. The second locking portion 334 is connected to the proximal locking claw 305 when the proximal end portion of the fixing pin 301 is inserted into the second insertion hole 333 and disposed at a preset rotational locking position. On the other hand, the fixing pin 301 is disposed so as to face the removal direction, and when the fixing pin 301 is urged in the removal direction, it comes into contact with the proximal end side locking claw 305 and the fixing pin 301 is removed. The movement in the direction is restricted and the fixing pin 301 is locked.

  In the present embodiment, as shown in FIG. 23, the second locking portion 334 is provided so as to protrude from the left and right within the second insertion hole 333 to form a pair. Each locking portion 334 is opposed along the outer peripheral surface of the shaft portion 302 of the fixing pin 301 in a state where the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330. It has a curved surface 335 that can be rotatably supported around an axis. The curved surface 335 has a radius slightly larger than the outer diameter of the shaft portion 302 around the same central axis as the second insertion hole 333, and is formed to be concavely curved.

  Of the end surfaces of the locking portions 334 located on both sides in the axial direction of the second insertion hole 333, the rear end surface 336 located on the rear side in the axial direction of the second insertion hole 333 is orthogonal to the axial direction of the second insertion hole 333. The base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 so that the claw portion 305b of the base end side locking claw 305 is inserted. When protruding from the rear end surface 336 of the locking portion 334 and disposed at the rotation locking position, the stepped surface of the claw portion 305b of the base end side locking claw 305 can be opposed.

  Therefore, in a state where the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 and disposed at the rotation locking position, the fixing pin 301 is moved in the removal direction. In this case, the stepped surface of the claw portion 305b of the proximal end side locking claw 305 abuts on the rear end surface 336 of the locking portion 334 and the movement of the fixing pin 301 in the removal direction is restricted, and the fixing pin 301 is engaged. Can be stopped.

  In addition, among the end surfaces of the locking portions 334 located on both sides in the axial direction of the second insertion hole 333, the front end surface 337 located on the front side in the axial direction of the second insertion hole 333 moves from the front side in the axial direction toward the rear side. It is formed in a tapered shape that gradually decreases in diameter. Accordingly, when the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330, it comes into contact with the inclined surface of the claw portion 305 b of the base end side locking claw 305, and each arm The part 305a can be urged toward the direction approaching each other to be elastically deformed, and can pass between a pair of curved surfaces 335 facing each other.

  The second passage portion 339 is arranged so that the proximal end portion of the fixing pin 301 is inserted into the second insertion hole 333 and disposed at a preset rotation release position with respect to the proximal end side locking claw 305. When the fixing pin 301 is urged toward the removal direction, the proximal end side locking claw 305 is passed through the fixing pin 301 to move in the removal direction. It has an acceptable configuration.

  The second passage portion 339 is formed between the pair of second locking portions 334, and is paired with being spaced apart vertically in the second insertion hole 333. The lateral width of the second passage portion 339 is larger than the lateral width of the claw portion 304b of the distal end side locking claw 304 and the claw portion 305b of the proximal end side locking claw 305, and when the fixing pin 301 is moved in the axial direction, The proximal end side locking claw 305 and the distal end side locking claw 304 can be passed.

  Then, the fixing pin 301 is rotated relative to the second insertion member 330 around the axis from the rotation locking position, so that the position of the claw portion 305b and the position of the second passage portion 339 coincide with each other. By moving, the second passage portion 339 can be positioned on the side of the fixing pin 301 with respect to the claw portion 305b, and the step surface of the claw portion 305b can be opposed to the rear end surface 336 of the locking portion 334. It can be canceled.

  Accordingly, the claw portion 305b can be passed through the second passage portion 339 when the fixing pin 301 is moved in the removal direction while the fixing pin 301 is disposed at the rotation release position. Therefore, the base end side portion of the fixing pin 301 can be easily detached from the second inserted member 330 without destroying the fixing pin 301.

  When the fixing pin 301 is moved in the removal direction and the base end side portion of the fixing pin 301 is removed from the second inserted member 330, the distal end side claw 304 of the fixing pin 301 is then moved to the second covered member. Contact with the second locking portion 334 of the insertion member 330 restricts the movement of the fixing pin 301 in the removal direction.

  Here, with respect to the second inserted member 330 in a state where the stepped surface of the claw portion 304 b of the front end side locking claw 304 is in contact with the rear end surface 336 of the second locking portion 334 of the second inserted member 330. When the fixing pin 301 is relatively rotated around the axis and moved to a position where the position of the claw portion 304b and the position of the second passage portion 339 coincide with each other, the fixing pin 301 is removed from the claw portion 304b. The 2nd channel | path part 339 can be located in the direction side, and the opposition of the level | step difference surface of the nail | claw part 304b with respect to the rear-end surface 336 of the 2nd latching | locking part 334 can be cancelled | released. Therefore, the claw portion 304b of the front end side locking claw 304 can be passed through the second passage portion 339, and the front end side portion of the fixing pin 301 can be easily attached to the second inserted member 330 without destroying the fixing pin 301. Can be removed from.

  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. The fixing pin 301 is inserted from the distal end side in a posture state in which the distal end side locking claws 304 are arranged vertically with respect to the second insertion hole 333.

  When the distal end portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330, the claw portion 304 b of the distal end side locking claw 304 is moved to the second passage portion 339 of the second inserted member 330. And the tip of the claw portion 304b is inserted from the second insertion hole 333 of the second inserted member 330 to the position immediately before entering the first insertion hole 313 of the first inserted member 310. Then, the claw portion 304b of each distal end side locking claw 304 abuts on the end portion of the first insertion hole 313 of the first inserted member 310, and the claw portion 305b of the proximal side locking claw 305 is the second engagement. The state is in contact with the front end surface 337 of the stopper 334.

  In this state, by further pressing the fixing pin 301, the distal end side claw 304 is urged in the direction in which the arm portion 304a is elastically deformed by the inclined surface of the claw portion 304b, and is directed radially inward of the shaft portion 302. And moves into the first insertion hole 313, passes through the first insertion hole 313, protrudes in the axial direction from the distal end surface 316a of the first locking portion 316, as shown in FIG. The rotation restricting portion 317 is interposed.

  When the claw portion 304b passes through the first insertion hole 313 and protrudes from the first locking portion 316, the urging is released, the arm portion 304a is restored and the deflection is restored, and the step surface of the claw portion 304b is restored. Is disposed at a position facing the front end surface 316 a of the first locking portion 316.

  On the other hand, the base end side locking claw 305 is biased in a direction in which the claw portion 305b abuts on the front end surface 337 of the locking portion 334 and elastically deforms the arm portion 305a. And the nail | claw part 305b moves toward the radial inside of the axial part 302, passes between a pair of latching | locking parts 334, and is more axial than the rear end surface 336 of the latching | locking part 334, as shown in FIG. Protrusively. When the claw portion 305b passes between the pair of locking portions 334 and protrudes in the axial direction from the rear end surface 336 of the locking portion 334, the urging force by the locking portion 334 is released, and the arm portion 305b is restored. The bending is restored to the original, and the step surface of the claw portion 305b is disposed at a position facing the rear end surface 336 of the locking portion 334.

  At this position, the fixing pin 301 has the bottom surface of the flange 303 substantially flush with the front end surface of the second inserted member 330. Then, the distal end of the distal side locking claw 304 faces the bottom surface of the round hole 321b, the distal end of the proximal side locking claw 305 faces the flat plate portion 312 of the first inserted member 310, and the hook portion 303 is engaged. The movement of the fixing pin 301 in the further insertion direction is restricted so as to face the front end surface 337 of the stopper 334.

  Here, when the fixing pin 301 is to be moved in the removal direction opposite to the insertion direction, the stepped surface of the claw portion 304b of the front end side locking claw 304 is the front end surface 316a of the first locking portion 316. And the stepped surface of the claw portion 305b of the proximal end side locking claw 305 contacts the rear end surface 336 of the locking portion 334, and the movement of the fixing pin 301 in the pulling direction is stopped.

  That is, the distal end portion of the fixing pin 301 is inserted into the first inserted member 310 and locked, the proximal end portion is inserted into the second inserted member 330 and locked, and the fixing pin 301 is locked to the first inserted member 310. It can be set as the state which cannot be removed from the insertion member 310 and the 2nd to-be-inserted member 330. FIG.

  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 portion 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.

As a result, the fixing pin 301 has a rear end portion that is locked to the second inserted member 330 and a distal end portion that is locked to the first inserted member 310 and the rear side of the fixed pin 301. The case body 120 is taken out. Therefore, the fixing of the substrate box 102 to the base device 201 by the regulating (fixing) member 300 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 moved. It can be removed from the base part 203.

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

  In order to remove the first inserted member 310 from the fixing pin 301, the claw portions 304b of the front end side locking claws 304 protruding from the first locking portion 316 of the first inserted member 310 are urged in a direction approaching each other. Then, the hook to the first locking portion 316 is removed, and the fixing pin 301 is urged in the direction of pulling out as it is. As a result, the claw portions 304b of the front end side locking claw 304 can be passed through the first insertion hole 313 in a state where they are bent toward each other, and the first inserted member 310 is removed from the fixing pin 301. Can do.

  Next, in order to remove the fixing pin 301 from the second inserted member 330, the fixing pin 301 is rotated by about 90 degrees around the axis relative to the first inserted member 310 to rotate and lock. The rotational movement is performed from the position (see FIG. 29) to the rotation release position, and the opposing of the step surface of the claw portion 305b of the proximal end side locking claw 305 and the rear end surface 336 of the second locking portion 334 is released.

  Then, the fixing pin 301 is moved in the removal direction as it is, and the claw portion 305 b is passed through the passage portion 339. When the claw portion 305b passes through the passage portion 339, the stepped surface of the claw portion 304b of the front end side locking claw 304 comes into contact with the rear end surface 336 of the second locking portion 334, and the movement of the fixing pin 301 in the pulling direction is performed. Be regulated.

  Here, the fixing pin 301 is rotated about 90 degrees around the axis with respect to the second inserted member 330, and the positions of the claw portion 304b of the front end side locking claw 304 and the second passage portion 339 are matched, The facing of the step surface of the claw portion 304b and the rear end surface 336 of the locking portion 334 is released.

  Then, the fixing pin 301 is moved in the removal direction as it is, the claw portion 304b is passed through the passage portion 339, the tip side portion of the fixing pin 301 is removed from the second inserted member 330, and the second from the fixing pin 301. The inserted member 330 can be removed.

  According to the fixing means 300, the locking to the second inserted member 330 can be released without directly touching the proximal end side locking claws 305, and the second insertion hole 333 of the second inserted member 330 can be released. The base end side portion of the fixing pin 301 can be pulled out from. Therefore, the second inserted member 330 can be easily removed from the fixing pin 301, and there is no possibility of breaking the fixing pin 301.

  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 the fixed pin 301 is broken and the movable base portion 203 and the substrate box 102 are fixed, 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 fixed by being inserted into the board.

  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.

  30 is a plan view of the pedestal device 201, and FIG. 31 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.

(Second Embodiment)
Next, a second embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

FIG. 35 is a sectional view of the fixing means 300 cut in the left-right direction along the axial direction of the fixing pin 301, and is a sectional view of the fixing pin 301 cut in the vertical direction along the axial direction of the fixing pin 301. is there.

  What is characteristic in the present embodiment is that the distal end side locking claws 304 and the proximal end side locking claws 305 of the fixing pin 301 are arranged so as to be aligned in a straight line in the axial direction of the shaft portion 302. This is a configuration that can be easily extracted when the second is inserted from the second inserted member 330.

  As described above, in the configuration of the first embodiment, the distal end side locking claw 304 and the proximal end side locking claw 305 of the fixing pin 301 have a positional relationship of a 90 degree phase angle. After the claw portion 305 b of the locking claw 305 is passed through the second passage portion 342, if the fixing pin 301 is moved in the removal direction as it is, the distal end side locking claw 304 is moved to the second engagement of the second inserted member 330. It is caught by the stopper 334 and the tip side portion of the fixing pin 301 cannot be extracted from the second insertion hole 333 of the second inserted member 330.

  Therefore, it is necessary to rotate the fixing pin 301 around the axis again so that the positions of the claw portion 304b of the distal end side locking claw 304 and the second passage portion 342 coincide with each other and pass through the second passage portion 342. . Therefore, in the present embodiment, the fixing means 300 has the following configuration so that the fixing pin 301 can be removed from the second inserted member 330 more easily.

  As shown in FIG. 32, the fixing pin 301 is configured such that the distal end side locking claws 304 and the proximal end side locking claws 305 are arranged in a straight line in the axial direction of the shaft portion 302. The distal end side locking claws 304 and the proximal end side locking claws 305 are arranged such that the claw portions 304b of the two distal end side locking claws 304 are separated from each other, and the claw portions 305b of the two proximal end side locking claws 305 are There is a positional relationship in which the direction of separation is a phase angle of 0 degrees.

  The distal end side locking claw 304 is formed such that the two claw portions 304b protrude radially outward from the shaft portion 302. Similarly, the proximal end side locking claw 305 is also formed of the two claw portions 305b. Is formed so as to protrude radially outward from the shaft portion 302. The claw portion 304b of the distal end side locking claw 304 and the claw portion 305b of the proximal end side locking claw 305 have substantially the same size.

  The first inserted member 310 has the same configuration as that in the first embodiment (see, for example, FIGS. 20 and 21).

  A second locking portion 341 and a second passage portion 342 are formed in the second insertion hole 333 of the second inserted member 330. The second locking portion 341 has a base end side locking claw 305 when the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 and disposed at a preset rotation locking position. When the fixing pin 301 is urged toward the removal direction, it comes into contact with the proximal end side locking claw 305 and the fixing pin 301 is removed. It has a configuration that restricts movement in the disengagement direction and locks the fixing pin 301.

  As shown in FIG. 33, the second locking portion 341 protrudes from the second insertion hole 333 so as to form a pair separated from each other in the vertical direction. The rear end surface 336 of the second insertion hole 333 inserts the base end side portion of the fixing pin 301 into the second insertion hole 333 of the second inserted member 330 so that the claw portion 305 b of the base end side locking claw 305 is inserted into the second insertion hole 333. When projecting from the rear end surface 336 of the second locking portion 341 and disposed at the rotational locking position, the stepped surface of the claw portion 305b of the base end side locking claw 305 can be opposed.

  Therefore, when the fixing pin 301 is urged in the removal direction in a state where the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 and arranged at the rotation locking position. Further, the stepped surface of the claw portion 305b of the base end side locking claw 305 contacts the rear end surface 336 of the second locking portion 341, and the movement of the fixing pin 301 in the removal direction is restricted, and the fixing pin 301 is engaged. Can be stopped.

  The second passage portion 342 is located on the base end side claw 305 when the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 and disposed at a preset rotation release position. When the fixing pin 301 is urged toward the removal direction, the proximal end side locking claw 305 is passed through to move the fixing pin 301 in the removal direction. It has an acceptable configuration.

  The second passage portion 342 is formed between the pair of second locking portions 341, and forms a pair in the second insertion hole 333 so as to be separated left and right. The width of the second passage portion 342 is larger than the lateral width of the claw portion 304b of the distal end side locking claw 304 and the claw portion 305b of the proximal end side locking claw 305, and when the fixing pin 301 is moved in the axial direction, The base end side locking claw 305 and the distal end side locking claw 304 have a size that can be easily passed.

  Then, when the fixing pin 301 is relatively rotated about the axis and moved from the rotation locking position to the rotation releasing position, the fixing pin 301 is moved in the second direction toward the removal direction of the fixing pin 301 with respect to the step surface of the claw portion 305b. The passage portion 342 is arranged so that the facing of the step surface of the claw portion 305b and the rear end surface 336 of the second locking portion 341 can be released.

  Therefore, when the fixing pin 301 is urged in the removal direction in a state where the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 and disposed at the rotation release position. The claw portion 305b of the base end side locking claw 305 can be passed through the second passage portion 342, the fixing pin 301 can be moved in the removal direction, and the base end side portion of the fixing pin 301 can be moved to the second portion. It can be removed from the second insertion hole 333 of the inserted member 330.

  Next, the usage method and operation of the fixing means 300 will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 300, first, the substrate box 102 is attached to the movable base portion 203 in a state where the first inserted member 310 is attached to and held by the fitting portion 321. And slide it on.

  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. The fixing pin 301 is inserted from the distal end side in a posture state in which the distal end side locking claws 304 are arranged vertically with respect to the second insertion hole 333.

  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 claw portion 304 b of the distal end side locking claw 304 contacts the front end surface 337 of the second locking portion 341. Touch.

  Then, by further pressing the fixing pin 301, the distal end side claw 304 is urged in the direction in which the arm portion 304a is elastically deformed by the inclined surface of the claw portion 304b, and moves toward the radially inner side of the shaft portion 302. Then, it enters between the pair of second locking portions 341, passes through the second insertion hole 333, protrudes in the axial direction from the rear end surface 336 of the second locking portion 341, and is inserted into the first inserted member 310. The first insertion hole 313 is inserted to the position immediately before entering.

  Then, the claw portion 304b of the distal end side locking claw 304 comes into contact with the end portion of the first insertion hole 313 of the first inserted member 310, and the claw portion 305b of the proximal end side locking claw 305 is second locked. The state is in contact with the front end surface 337 of the portion 341.

  In this state, by further pressing the fixing pin 301, the distal end side claw 304 is urged in the direction in which the arm portion 304a is elastically deformed by the inclined surface of the claw portion 304b, and is directed radially inward of the shaft portion 302. 34, move into the first insertion hole 313, pass through the first insertion hole 313, and in the axial direction from the distal end surface 316a of the first locking portion 316 as shown in FIGS. It protrudes and is interposed between the left and right rotation restricting portions 317.

  When the claw portion 304b of the distal end side locking claw 304 passes through the first insertion hole 313 and protrudes from the first locking portion 316, the urging is released, the arm portion 304a is restored, and the deflection is restored. The step surface of the claw portion 304b is disposed at a position facing the tip surface 316a of the first locking portion 316.

  On the other hand, the base end side locking claw 305 is urged in a direction in which the claw portion 305b contacts the front end surface 337 of the second locking portion 341 and elastically deforms the arm portion 305a. Then, the claw portion 305b of the proximal end side locking claw 305 moves toward the inside in the radial direction of the shaft portion 302 and passes between the pair of second locking portions 341, as shown in FIGS. Further, it protrudes in the axial direction from the rear end surface 336 of the second locking portion 341. When the claw portion 305b passes between the pair of second locking portions 341 and protrudes in the axial direction from the rear end surface 336 of the second locking portion 341, the urging is released and the arm portion 305a is restored. The bending is returned to the original, and the step surface of the claw portion 305b is disposed at a position facing the rear end surface 336 of the second locking portion 341.

  At this position, the fixing pin 301 has the bottom surface of the flange 303 substantially flush with the front end surface of the second inserted member 330. The distal end of the distal end side locking claw 304 faces the bottom surface of the round hole portion 321b, the distal end of the proximal side locking claw 305 faces the flat plate portion 312 of the first inserted member 310, and the flange portion 303 The movement of the fixing pin 301 in the further insertion direction is restricted so as to face the front end surface 337 of the two locking portions 341.

  Here, when the fixing pin 301 is to be moved in the removal direction opposite to the insertion direction, the stepped surface of the claw portion 304b of the front end side locking claw 304 is the front end surface 316a of the first locking portion 316. And the stepped surface of the claw portion 305b of the proximal end side locking claw 305 contacts the rear end surface 336 of the second locking portion 341, and the movement of the fixing pin 301 in the pulling direction is stopped.

  That is, the distal end portion of the fixing pin 301 is inserted into the first inserted member 310 and locked, the proximal end portion is inserted into the second inserted member 330 and locked, and the fixing pin 301 is locked to the first inserted member 310. The insertion member 310 and the second inserted member 330 cannot be removed.

  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.

  Next, the first inserted member 310 is separated from the movable base portion 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.

  Accordingly, the fixing pin 301 has a proximal end portion inserted into the second insertion hole 333 of the second inserted member 330 and locked therein, and a distal end portion thereof inserted into the first insertion hole 313 of the first inserted member 310. In the state of being inserted and locked, the movable base portion 203 and the back case body 120 are taken out.

  Accordingly, the fixing of the substrate box 102 to the pedestal device 201 by the fixing pin 301 is released, and the substrate box 102 can be slid in the sliding direction with respect to the movable base portion 203, and the substrate box 102 is moved in the sliding direction. Can be removed from.

  When the fixing pin 301 is removed from the first insertion hole 313 of the first inserted member 310 and the second insertion hole 333 of the second inserted member 330, the distal end portion of the fixing pin 301 is first removed, and then Pull out the proximal end part.

  First, in order to remove the fixing pin 301 from the first insertion hole 313 of the first inserted member 310, the claw of the distal end side locking claw 304 protruding from the first locking portion 316 of the first inserted member 310. The portion 304b is urged in the direction of approaching each other, the hook to the first locking portion 316 is removed, and the fixing pin 301 is urged as it is.

  As a result, the claw portions 304b of the front end side locking claw 304 can be passed through the first insertion hole 313 while being bent in a direction approaching each other, and the fixing pin 301 can be passed through the first insertion member 310 in the first direction. It can be removed from the insertion hole 313.

  Next, in order to remove the fixing pin 301 from the second insertion hole 333 of the second inserted member 330, the fixing pin 301 is rotated about 90 degrees around the axis relative to the second inserted member 330. Thus, the rotation is moved from the rotation locking position to the rotation releasing position, and the opposing of the step surface of the claw portion 305b of the base end side locking claw 305 and the rear end surface 336 of the second locking portion 341 is released.

  Then, the fixing pin 301 is moved in the removal direction while maintaining the rotation angle position. Accordingly, the claw portion 305 b can be passed through the passage portion 339, and the proximal end side portion of the fixing pin 301 can be removed from the second insertion hole 333 of the second inserted member 330.

  Further, by further moving the fixing pin 301 in the removal direction as it is, the claw portion 304b of the front end side locking claw 304 can be passed through the second passage portion 342, and the front end side portion of the fixing pin 301 is moved to the second side. The insertion member 330 can be removed from the second insertion hole 333.

  As described above, after the fixing pin 301 is rotated around the axis to release the locking to the second inserted member 330 by the proximal-side locking claw 305, the fixing pin 301 is moved to the second inserted member 330. The base end side portion and the tip end side portion of the fixing pin 301 can be removed from the second insertion hole 333 of the second inserted member 330 only by relatively moving in the removal direction.

  Therefore, there is no need to rotate the fixing pin 301 again in order to extract the tip side portion of the fixing pin 301 from the second insertion hole 333 of the second insertion member 330, and the second insertion target can be more easily inserted from the fixing pin 301. The member 330 can be removed.

(Third embodiment)
Next, a third embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 36 is a perspective view illustrating the configuration of the fixing pin 301 in the third embodiment, and FIG. 37 is a cross-sectional view of the fixing means 300, which is a cross-section cut in the left-right direction along the axial direction of the fixing pin 301. FIG. 38 and FIG. 38 are cross-sectional views of the fixing means 300, which are cut in the vertical direction along the axial direction of the fixing pin 301.

  What is characteristic in the present embodiment is that the distal end side locking claw 304 of the fixing pin 301 in the first embodiment is formed to be smaller than the proximal end side locking claw 305, and the distal end side portion of the fixing pin 301 is The second insertion member 330 is configured to be easily removed from the second insertion hole 333 when it is removed from the second insertion hole 333.

  In the above-described first embodiment, the case where the distal end side locking claws 304 and the proximal end side locking claws 305 have the same radial size has been described. When pulling out from the second inserted member 330, the distal end side locking claw 304 is caught by the second locking portion 334 of the second inserted member 330.

  Therefore, it is necessary to rotate the fixing pin 301 around the axis again so that the positions of the claw portion 304b of the distal end side locking claw 304 and the second passage portion 339 are matched and passed through the second passage portion 339. .

  In the second embodiment, since the distal end side locking claws 304 and the proximal end side locking claws 305 have the same phase positional relationship, the distal end side portion of the fixing pin 301 is removed from the second inserted member 330. Sometimes, it is not necessary to rotate the fixing pin 301 around the axis, but there is a possibility that the tip end side locking claw 304 may be caught by the second passage portion 339 when passing through the second passage portion 339. Therefore, in the present embodiment, fixing means 300 has the following configuration so that it can be removed more easily.

  As shown in FIG. 36, the distal end side locking claw 304 and the proximal end side locking claw 305 of the fixing pin 301 have a direction in which the two claw portions 304b are separated from each other and the direction in which the two claw portions 305b are separated from each other by 90 degrees. The positional relationship becomes the phase angle.

  In the distal end side locking claw 304, the two claw portions 304b are positioned radially inward of the shaft portion 302, and in the proximal end side locking claw 305, the two claw portions 305b are radially outward from the shaft portion 302. It is formed so as to protrude toward.

  That is, the front end side locking claw 304 is formed such that the maximum separation distance between the two claw portions 304b is equal to or smaller than the outer diameter of the shaft portion 302, and the front end side portion of the fixing pin 301 is inserted into the second inserted portion. When passing through the second insertion hole 333 of the member 330, the claw portion 304 b can pass through without being caught by the second locking portion 334. The second inserted member 330 has the same configuration as that of the first embodiment (not shown) (see, for example, FIG. 23).

  Therefore, without affecting the rotational angle position of the distal end side locking claw 304, the distal end side portion of the stationary pin 301 can be moved by simply moving the stationary pin 301 in the removal direction with respect to the second inserted member 330. The second insertion member 330 can be removed from the second insertion hole 333.

  Therefore, it is not necessary to rotate the fixing pin 301 in order to remove the distal end side portion of the fixing pin 301 from the second insertion hole 333 of the second inserted member 330, and it can be more easily removed.

  In the above-described third embodiment, the fixing pin 301 has been described by taking as an example a case where the distal end side locking claw 304 and the proximal side locking claw 305 have a positional relationship of a 90 degree phase angle. Any phase angle may be used. For example, the distal end side locking claws 304 and the proximal end side locking claws 305 may have a positional relationship where the phase angle is 0 degree.

  The fixing pin 301 has a distal end side locking claw 304 and a proximal end side locking claw 305 provided on the shaft portion 302 independently of each other. For example, the distal end side locking claw 304 is arranged on the radially inner side of the shaft portion 302. Although the base end side locking claw 305 has a configuration that does not bend even if it is bent toward the front, it is not limited to this configuration. For example, as shown in a fourth embodiment described later. The distal end side locking claws 304 may be provided continuously at the distal end of the proximal end side locking claws 305.

  What is characteristic in the present embodiment is that the fixing pin 301 has a configuration in which a distal end side locking claw 304 is continuously provided at the distal end of the proximal end side locking claw 305. As shown in FIG. 39, the proximal end side locking claw 305 of the fixing pin 301 is fixed at the base end to the flange portion 303, and the distal end side locking claw 304 is continuous with the distal end of each proximal end side locking claw 305. Is provided. The arm portion 305a of the proximal end side locking claw 305 has a substantially semicircular cross section and extends in the axial direction. The planar portions of the arms 305a face each other with a predetermined gap, and the arc portions of the arms 305a cooperate to form a single large-diameter shaft.

  The claw portions 305b of the base-end side locking claw 305 are provided so as to protrude in the direction in which the arm portions 305a are separated from each other, and are formed in a stepped shape so as to be substantially perpendicular to the arm portions 305a. It has a stepped surface and a tapered surface that gradually decreases in diameter toward the axial center of the fixing pin 301 as it moves from the outer edge of the stepped surface toward the tip end side in the axial direction of the fixing pin 301.

  The stepped surface faces the rear end surface 336 of the second locking portion 343 of the second inserted member 330 when the proximal end portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330. It is formed so that it can be made.

  The tapered surface comes into contact with the inner peripheral surface of the second insertion hole 333 when the proximal end portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 so that the arm portions 305a approach each other. It is formed so that it can be elastically deformed by being urged in the direction.

  The tip end portion in the axial direction of the claw portion 305b is formed so as to be located radially inward from the outer diameter of the large-diameter shaft portion. And the chamfering process is given to the axial direction base end part of the nail | claw part 305b so that it may become the horizontal width same as the horizontal width of the arm part 305a.

  The respective arm portions 305a of the proximal end side locking claws 305 are elastically deformed in the directions approaching each other by urging them in the directions approaching each other, and are restored by the disappearance of the urging force to be restored to the original positions. It is comprised so that it can return to a position.

  The distal end side locking claw 304 has an arm portion 304a having a substantially semicircular cross section and extending in the axial direction. The arm portion 304a of each of the front end side locking claws 304 has one small-diameter shaft portion whose two flat portions are opposed to each other with a predetermined gap and two arc portions have a constant diameter. It arrange | positions so that it may form coaxially with a part.

  A claw portion 304b projects from the tip portion of the arm portion 304a. The claw portions 304b are provided so as to protrude from the arm portions 304a in a direction away from each other. The step portions are formed in a step shape so as to be substantially perpendicular to the arm portions 304a, and outside the step surfaces. The taper has a tapered surface that gradually decreases in diameter toward the axial center of the fixing pin 301 as it moves from the end edge toward the distal end side in the axial direction of the fixing pin 301.

  The stepped surface is opposed to the distal end surface 316a of the first locking portion 316 of the first inserted member 310 when the distal end side portion of the fixing pin 301 is inserted into the first insertion hole 313 of the first inserted member 310. It is formed so that it can be.

  The tapered surface comes into contact with the inner peripheral surface of the first insertion hole 313 to approach the arm portions 304a when the distal end portion of the fixing pin 301 is inserted into the first insertion hole 313 of the first inserted member 310. It can be elastically deformed by being biased in the direction.

  The tip end portion in the axial direction of the claw portion 304b is formed so as to be positioned radially inward from the outer diameter of the small-diameter shaft portion. The claw portion 304b is chamfered at the proximal end portion in the axial direction so as to have the same width as that of the arm portion 304a, and comes into contact with the rotation restricting portion 317 of the first inserted member 310. The rotational movement around the axis of the fixed pin 301 is restricted.

  Each arm portion 304a of the front end side locking claw 304 is elastically deformed in a direction approaching each other by urging in a direction approaching each other, and is restored by the disappearance of the urging force and restored to its original position. It is comprised so that it can return to.

  Even if the arm portion 305a of the proximal end side locking claw 305 grips the two claw portions 304b of the distal end side locking claw 304 from the outside and urges them toward each other, It can be maintained in a state of being locked to the second locking portion 343 of the second inserted member 330, and the claw portions 304 b of the respective base end side locking claws 304 are picked from the radially outer side so as to approach each other. When energized, the elastic strength is set so that the locking of the proximal locking claws 305 with respect to the second locking portion 343 can be released.

  The distal end side locking claws 304 and the proximal end side locking claws 305 are positioned such that the direction in which the distal end side locking claws 304 are separated from each other and the direction in which the proximal end side locking claws 305 are separated form a phase angle of 0 degree. Have a relationship.

  The front end side locking claw 304 is formed in such a size that the maximum separation distance between the two claw portions 304b is equal to or smaller than the maximum separation distance between the two arm portions 305a. When it is passed through the second insertion hole 333 of the insertion member 330, the claw portion 304b can be passed in the removal direction without being caught by the second locking portion 343.

  The first inserted member 310 has the same configuration as that in the first embodiment (see, for example, FIGS. 20 and 21).

  As shown in FIG. 40, the second inserted member 330 has a second locking portion 343 and a second passage portion 344 in the second insertion hole 333. The second locking portion 343 protrudes from the second insertion hole 333 so as to form a pair spaced apart in the vertical direction. The rear end surface 336 of the second locking portion 343 inserts the base end side portion of the fixing pin 301 into the second insertion hole 333 of the second inserted member 330 so that the claw portion 305b of the base end side locking claw 305 is inserted. When protruding from the rear end surface 336 of the second locking portion 343 and disposed at the rotation locking position, the stepped surface of the claw portion 305b of the base end side locking claw 305 is opposed.

  Accordingly, the fixing pin 301 is urged in the removal direction in a state where the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 of the second inserted member 330 and disposed at the rotation locking position. In this case, the stepped surface of the claw portion 305b of the proximal end side locking claw 305 abuts on the rear end surface 336 of the second locking portion 343, and the movement of the fixing pin 301 in the removal direction is restricted. Can be locked.

  The second passage portion 344 is located on the base end side locking claw 305 when the base end side portion of the fixing pin 301 is inserted into the second insertion hole 333 and disposed at a preset rotation release position. When the fixing pin 301 is urged toward the removal direction, the proximal end side locking claw 305 is passed through the fixing pin 301 to move in the removal direction. It has an acceptable configuration.

  The second passage portion 344 is formed between the pair of second locking portions 343, and forms a pair in the second insertion hole 333 so as to be spaced apart vertically. The lateral width of the second passage portion 344 is larger than the lateral width of the claw portion 305b of the proximal end side locking claw 305, and when the fixing pin 301 is moved in the axial direction, the proximal end side locking claw 305 is allowed to pass. Can be done.

  Then, the fixing pin 301 is rotated relative to the second insertion member 330 around the axis from the rotation locking position, so that the position of the claw portion 305b and the position of the second passage portion 344 coincide with each other. By moving, the second passage portion 344 can be positioned on the side of the fixing pin 301 with respect to the claw portion 305b, and the step surface of the claw portion 305b with respect to the rear end surface 336 of the second locking portion 343 can be positioned. Opposite can be released.

  Therefore, when the fixing pin 301 is moved in the removal direction in a state where the fixing pin 301 is disposed at the rotation release position, the claw portion 305b can be passed through the second passage portion 344. Therefore, the base end side portion of the fixing pin 301 can be easily removed from the second insertion hole 333 of the second inserted member 330 without destroying the fixing pin 301.

  Next, the usage method and operation of the fixing means 300 in the fourth embodiment will be described. In order to fix the substrate box 102 to the movable base portion 203 by the fixing means 300, first, the substrate box 102 is mounted in a state where the first inserted member 310 is attached and held in the fitting portion 321 of the first inserted member 310. Is attached to the movable base 203 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. The fixing pin 301 is inserted from the distal end side in a posture state in which the distal end side locking claws 304 are arranged vertically with respect to the second insertion hole 333.

  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 claw portion 304 b of the distal end side locking claw 304 contacts the front end surface 337 of the second locking portion 343. Touch.

  Then, by further pressing the fixing pin 301, the distal end side locking claw 304 is elastically deformed by being biased in the direction in which the arm portions 304a approach each other by the tapered surface of the claw portion 304b, and a pair of second locking portions. , The claw portion 304b passes through the second insertion hole 333, protrudes in the axial direction from the rear end surface 336 of the second locking portion 343, and the first insertion hole 313 of the first inserted member 310 is inserted. It is arranged at the position just before entering.

  Then, the claw portion 304b of the distal end side locking claw 304 comes into contact with the end portion of the first insertion hole 313 of the first inserted member 310, and the claw portion 305b of the proximal end side locking claw 305 is second locked. The state is in contact with the front end surface 337 of the portion 343.

  From this state, by further pressing the fixing pin 301, the distal end side locking claw 304 is elastically deformed by being biased in the direction in which the arm portions 304a approach each other by the taper surface of the claw portion 304b. The claw portion 304b passes through the first insertion hole 313, protrudes in the axial direction from the distal end surface 316a of the first locking portion 316, and is interposed between the left and right rotation restricting portions 317.

  When the claw portion 304b of the distal end side locking claw 304 passes through the first insertion hole 313 and protrudes from the first locking portion 316, the urging is released, the arm portion 304a is restored, and the deflection is restored. The step surface of the claw portion 304b is disposed at a position facing the tip surface 316a of the first locking portion 316. Therefore, the tip side portion of the fixing pin 301 is locked to the first inserted member 310 in a state where the rotation of the fixing pin 301 around the axis is restricted.

  On the other hand, the base end side locking claw 305 is biased in a direction in which the claw portion 305b abuts on the front end surface 337 of the second locking portion 343 and the arm portions 305a approach each other. Then, the claw portion 305 b of the proximal end side locking claw 305 moves toward the inside in the radial direction of the shaft portion 302 and passes between the pair of second locking portions 343, and the rear of the second locking portion 343. It protrudes in the axial direction from the end face 336. When the claw portion 305b passes between the pair of second locking portions 343 and protrudes in the axial direction from the rear end surface 336 of the second locking portion 343, the urging is released and the arm portion 305a is restored. The bending is returned to the original, and the step surface of the claw portion 305b is disposed at a position facing the rear end surface 336 of the second locking portion 343.

  At this position, the fixing pin 301 has the bottom surface of the flange 303 substantially flush with the front end surface of the second inserted member 330. The distal end of the distal end side locking claw 304 faces the bottom surface of the round hole portion 321b, the distal end of the proximal side locking claw 305 faces the flat plate portion 312 of the first inserted member 310, and the flange portion 303 2 The movement in the further insertion direction of the fixing pin 301 is restricted facing the front end surface 337 of the locking part 343.

  Here, when the fixing pin 301 is to be moved in the removal direction opposite to the insertion direction, the stepped surface of the claw portion 304b of the front end side locking claw 304 is the front end surface 316a of the first locking portion 316. And the stepped surface of the claw portion 305b of the proximal end side locking claw 305 contacts the rear end surface 336 of the second locking portion 343, and the movement of the fixing pin 301 in the pulling direction is stopped.

  That is, the distal end portion of the fixing pin 301 is inserted into the first inserted member 310 and locked, the proximal end portion is inserted into the second inserted member 330 and locked, and the fixing pin 301 is locked to the first inserted member 310. It can be set in a state where it cannot be extracted from the first insertion hole 313 of the insertion member 310 and the second insertion hole 333 of 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, first, the fixing of the second inserted member 330 to which the fixing pin 301 is locked and the back case body 120 of the board box 102 is released, and then The first inserted member 310 is removed from the movable base portion 203.

  As a result, the fixing pin 301 has a rear end portion that is locked to the second inserted member 330 and a distal end portion that is locked to the first inserted member 310 and the rear side of the fixed pin 301. The case body 120 is taken out. Accordingly, the fixing of the substrate box 102 to the pedestal device 201 by the fixing pin 301 is released, and the substrate box 102 can be slid in the sliding direction with respect to the movable base portion 203, and the substrate box 102 is moved in the sliding direction. Can be removed from.

  When the fixing pin 301 is removed from the first inserted member 310 and the second inserted member 330, the distal end side portion of the fixing pin 301 is first removed, and then the proximal end portion is removed.

  First, in order to remove the fixing pin 301 from the first inserted member 310, the claw portions 304b of the distal end side locking claws 304 protruding from the first locking portion 316 of the first inserted member 310 are brought close to each other. By urging in the direction, the locking to the first locking portion 316 is released, and the fixing pin 301 is urged in the direction of pulling out as it is.

  As a result, the claw portions 304b of the front end side locking claw 304 can be passed through the first insertion hole 313 in a state where they are bent toward each other, and the front end side portion of the fixing pin 301 can be passed through the first inserted member. The first insertion hole 313 of 310 can be removed.

  Next, in order to remove the fixing pin 301 from the second inserted member 330, first, the fixing pin 301 is rotated by about 90 degrees around the axis relative to the second inserted member 330. Then, the rotation is moved from the rotation locking position to the rotation releasing position, and the opposing of the step surface of the claw portion 305b of the base end side locking claw 305 and the rear end surface 336 of the second locking portion 343 is released.

  Then, the fixing pin 301 is moved in the removal direction as it is, the claw portion 305 b is passed through the second passage portion 344, and the base end side portion of the fixing pin 301 is passed through the second insertion hole 333 of the second inserted member 330. Pull out.

  The front-end side locking claw 304 of the fixing pin 301 is formed in such a size that the maximum separation distance between the two claw portions 304b is less than or equal to the maximum separation distance between the two arm portions 305a. The tip side portion of the fixing pin 301 can be removed from the second insertion hole 333 of the second inserted member 330 simply by moving in the removal direction.

  Therefore, there is no need to rotate the fixing pin 301 again in order to remove the tip side portion of the fixing pin 301 from the second insertion hole 333 of the second inserted member 330, and the second fixing pin 301 can be easily connected to the second pin 301. It can be removed from the inserted member 330.

(Fifth embodiment)
Next, a fifth 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.

  43 is a perspective view showing the first inserted member 310, FIG. 44 is a view taken in the direction of the arrow X in FIG. 43, FIG. 45 is a perspective view of the back case body 120, and FIG. 47 is a diagram for explaining a coupling state between the fixing pin 301 and the first inserted member 310, and FIG. 48 is a diagram illustrating a coupling state between the fixing pin 301 and the second inserted member 330. FIG. It is a figure shown by a partial cross section.

  What is characteristic in the present embodiment is that the rotation restricting portion is provided in the first inserted member 310 and the second inserted member 330, and the rotation of the fixing pin 301 is restricted by the cooperation of both rotation restricting portions. It is that.

  In each of the above-described embodiments, the rotation restricting portion 317 provided on the first inserted member 310 restricts the rotation of the fixing pin 301 to one side in the rotation direction and the other side in the rotation direction. A first rotation restricting portion 361 that restricts rotation of the fixing pin 301 in one direction of rotation is provided in the first inserted member 310, and a second rotation restricting portion 371 that restricts rotation of the fixing pin 301 in the other direction of rotation. Is provided in the second inserted member 330.

  The fixing pin 301 has the same configuration as that in the first embodiment.

  As shown in FIGS. 43 and 44, the first inserted member 310 has a pair of first rotation restricting portions 361. The two first rotation restricting portions 361 extend from the front end surface 316a of the first locking portion 316 along the axial direction of the first locking portion 316, and are separated from each other in the radial direction of the first locking portion 316. ing. One is disposed at an oblique upper position of the first locking portion 316 (right oblique upper position in FIG. 47) on one side in the horizontal direction of the flat plate portion 312, and the first locking portion is disposed on the other lateral side of the flat plate portion 312. It is arranged at an oblique lower position 316 (left oblique lower position in FIG. 47).

  For example, as shown in FIG. 47, each first rotation restricting portion 361 has a distal end side portion of the fixing pin 301 inserted into the first insertion hole 313 of the first inserted member 310 so that the front end side claw 304 has a claw. When the portion 304b protrudes in the axial direction from the distal end surface 316a of the first locking portion 316 and each claw portion 304b is spaced apart vertically, one side in the rotational direction of each distal end side locking claw 304 ( 48, the first facing surfaces 361a are provided to face each other in the clockwise direction.

  When the fixing pin 301 is to be rotated toward one side in the rotation direction, the front end side claw 304 is brought into contact with the first facing surface 361a so that the fixing pin 301 does not rotate in one direction in the rotation direction. It has the structure which regulates to.

  As shown in FIGS. 46 and 48, the second inserted member 330 has a pair of second rotation restricting portions 371. The two second rotation restricting portions 371 project from the second insertion hole 333 and are separated from each other in the radial direction of the second insertion hole 333. One is arranged at one side in the second insertion hole 333 in the lateral direction and at an oblique upper position (right oblique upper position in FIG. 46), and the other is at the other side in the second insertion hole 333 and obliquely lower. It is arranged at a position (in FIG. 46, a left oblique lower position).

  For example, as shown in FIG. 48, each second rotation restricting portion 371 has a proximal end side portion of the fixing pin 301 inserted into the second insertion hole 333 of the second inserted member 330 so as to When the claw portion 305b protrudes in the axial direction from the rear end surface 336 of the second locking portion 334, and each claw portion 305b is spaced apart in the lateral direction, the rotation direction of each proximal end side locking claw 305 A second facing surface 372 is provided to face the other side (counterclockwise side in FIG. 48).

  In the present embodiment, each second rotation restricting portion 371 has a part of the rear end surface 336 of the second locking portion 334 on the rear side in the axial direction through a step, as particularly shown in FIG. It is formed by making it protrude toward.

  When the fixing pin 301 is to be rotated toward the other side in the rotation direction, the proximal end side claw 305 is brought into contact with the second facing surface 372 so that the rotation pin 301 does not rotate toward the other side in the rotation direction. It has the structure which regulates like this.

  Next, the usage method and operation of the fixing means 300 in the fifth embodiment will be described.

  The substrate box 102 is mounted on the movable base 203, the distal end portion of the fixing pin 301 is inserted into the first insertion hole 313 of the first inserted member 310, and the second insertion hole 333 of the second inserted member 330 is based on the second insertion hole 333. When the end portion is inserted, as shown in FIG. 47, the two claw portions 304b of the front end side locking claw 304 protrude in the axial direction from the front end surface 316a of the first locking portion 316 and are spaced apart vertically. And disposed opposite to the front end surface 316a of the first locking portion 316. And the 1st opposing surface 361a is each arrange | positioned facing the rotation direction one side (FIG. 47 clockwise direction) of each front end side latching claw 304, respectively.

  Further, as shown in FIG. 48, the two claw portions 305b of the base end side locking claw 305 are arranged at positions that protrude in the axial direction from the rear end surface 336 of the second locking portion 334 and are separated from each other left and right. The second locking portion 334 is disposed to face the rear end surface 336. And the 2nd opposing surface 372 is each arrange | positioned facing the rotation direction other side (in FIG. 48 counterclockwise side) of each base end side latching claw 305, respectively.

  Therefore, the distal end portion of the fixing pin 301 is locked to the first inserted member 310, and the proximal end portion of the fixing pin 301 is locked to the second inserted member 330. Thereby, for example, when the fixing pin 301 is urged in the removal direction, the two claw portions 304b of the distal end side locking claw 304 are caught by the first locking portion 316 and the proximal end side locking claw 305 is moved. The two claw portions 305b are hooked on the second locking portion 334, and the movement of the fixing pin 301 in the removal direction of the first inserted member 310 and the second inserted member 330 can be restricted.

  In this locked state, the fixing pin 301 is prevented from rotating in one direction of rotation by the first facing surface 361a, and is prevented from rotating in the other direction by the second facing surface 372.

  Accordingly, until the second inserted member 330 is separated from the second member by cutting the gate portion 331, the relative rotation of the fixing pin 301 with respect to the second inserted member 330 is restricted, and the proximal end side locking claw 305 is controlled. The locking to the second locking portion 334 cannot be released, and the fixing pin 301 is removed from the first insertion hole 313 of the first inserted member 310 and the second insertion hole 333 of the second inserted member 330. It can be maintained in a state where it cannot be removed.

  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.

  On the other hand, in order to release the fixation of the substrate box 102 with respect to the movable base portion 203, first, the second inserted member 330 to which the fixing pin 301 is locked is moved by cutting the gate portion 331. After separating from the back case body 120, the first inserted member 310 is then removed from the movable base portion 203.

  As a result, the fixing pin 301 is in a state where the base end side portion is inserted and locked into the second inserted member 330 and the distal end portion is inserted and locked into the first inserted member 310. It is taken out from the movable base part 203 and the back case body 120 as it is.

  Accordingly, the fixing of the substrate box 102 to the pedestal device 201 by the fixing pin 301 is released, and the substrate box 102 can be slid in the sliding direction with respect to the movable base portion 203, and the substrate box 102 is moved in the sliding direction. Can be removed from.

  When removing the first inserted member 310 and the second inserted member 330 from the fixing pin 301, first, the first inserted member 310 is first moved from the distal end side portion of the fixing pin 301 toward the distal end and removed. . Next, the second inserted member 330 is moved from the proximal end side portion of the fixing pin 301 to the distal end side portion, and then moved from the distal end side portion toward the distal end side to be removed.

  In order to remove the first inserted member 310 from the fixing pin 301, the claw portions 304b of the front end side locking claws 304 protruding from the first locking portion 316 of the first inserted member 310 are urged in a direction approaching each other. Then, the locking to the first locking portion 316 is released, and the fixing pin 301 is urged in the direction of pulling out as it is.

  As a result, the claw portions 304b of the front end side locking claw 304 can be passed through the first insertion hole 313 in a state where they are bent toward each other, and the front end side portion of the fixing pin 301 can be passed through the first inserted member. The first insertion hole 313 of 310 can be removed. Therefore, the first inserted member 310 can be removed from the tip side portion of the fixing pin 301.

  In order to remove the second inserted member 330 from the fixing pin 301, the fixing pin 301 is relatively rotated about one axis relative to the second inserted member 330 in one direction of rotation (clockwise in FIG. 48). And the rotational movement from the rotation locking position to the rotation release position to release the opposite of the stepped surface of the claw portion 305b of the proximal locking claw 305 and the rear end surface 336 of the second locking portion 334. .

  Then, the fixing pin 301 is moved in the removal direction as it is, and the claw portion 305 b is passed through the second passage portion 339. As a result, the second inserted member 330 can be moved from the proximal end portion of the fixing pin 301 to the distal end portion.

  Next, in order to remove the second inserted member 330 from the distal end side portion of the fixing pin 301, the fixing pin 301 is rotated by about 90 degrees around the axis relative to the second inserted member 330, The positions of the claw portion 304b of the side locking claw 304 and the second passage portion 339 are made to coincide with each other, so that the stepped surface of the claw portion 304b and the rear end surface 336 of the first locking portion 334 are released.

  Then, the fixing pin 301 is moved in the removal direction as it is, the claw portion 304b is passed through the second passage portion 339, and the tip side portion of the fixing pin 301 is removed from the second insertion hole 333 of the second inserted member 330. Can be removed. Therefore, the second inserted member 330 can be removed from the tip side portion of the fixing pin 301.

  According to the fixing means 300, the locking to the second inserted member 330 can be released without directly touching the proximal end side locking claws 305, and the second insertion hole 333 of the second inserted member 330 can be released. The base end side portion of the fixing pin 301 can be pulled out. Therefore, the second inserted member 330 can be easily removed from the fixing pin 301, and there is no possibility of breaking the fixing pin 301.

  For the fixing pin 301, the case where the distal end side locking claw 304 and the proximal end side locking claw 305 have a positional relationship of a phase angle of 90 degrees has been described as an example. The distal end side locking claws 304 and the proximal end side locking claws 305 may have a positional relationship with a phase angle of 0 degree. When the distal end side locking claws 304 and the proximal end side locking claws 305 of the fixing pin 301 have a positional relationship with a phase angle of 0 degrees, the above-described second inserted member 330 has each second locking portion 334. It has the structure arrange | positioned in the position spaced apart up and down.

  The fixing pin 301 has a distal end side locking claw 304 and a proximal end side locking claw 305 provided on the shaft portion 302 independently of each other. Although the base end side claw 305 has a configuration that does not bend even if it is bent toward the bottom, it is not limited to this configuration. For example, as shown in the fourth embodiment, It is good also as a structure by which the front end side latching claw 304 was continuously provided in the front-end | tip of the end side latching claw 305. FIG.

(Sixth embodiment)
Next, a sixth embodiment will be described below based on 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. 49 is a diagram illustrating the configuration of the first inserted member 310. What is characteristic in the present embodiment is that the fixing pin 301 rotates relative to the first inserted member 310 from the state in which the distal end portion of the fixing pin 301 is locked to the first inserted member 310. This is a configuration in which the locking with respect to the first inserted member 310 can be released when it is rotated in the other direction.

  The fixing pin 301 has the same configuration as that in the first embodiment.

  As shown in FIG. 49, the first inserted member 310 is provided with a pair of slits (first passage portions) 381.

  Each slit 381 is formed by cutting out part of the flat plate portion 312 and the first locking portion 316 toward the radially outer side than the first insertion hole 313.

  The two slits 383 are provided so as to be separated from each other in the radial direction of the first insertion hole 313 and in the direction orthogonal to the direction in which the two rotation restricting portions 362 are separated. One side is disposed at an obliquely lower position (right obliquely lower position in FIG. 49) with respect to the first insertion hole 313 on the side, and an oblique upper position with respect to the first insertion hole 313 on the other lateral side of the flat plate portion 312 (see FIG. 49, the other is arranged at the upper left position).

  Each slit 381 rotates the fixing pin 301 relative to the first inserted member 310 from a state in which the front end side claw 304 of the fixing pin 301 is arranged vertically (a state indicated by a solid line in FIG. 49). When it is rotated to the other side of the direction (counterclockwise in FIG. 49) by a preset rotation angle (indicated by the phantom line in FIG. 49), it coincides with the position of the distal end side locking claw 304 and The step surface of the claw 304 and the front end surface 316a of the first locking portion 316 are released from each other, and the front end side locking claw 304 can be passed along the axial direction of the first insertion hole 313. ing.

  Next, a method for removing the first inserted member 310 from the distal end side portion of the fixing pin 301 and its operation and effect will be described below. Note that a method of fixing the substrate box to the movable base portion using the fixing pins 301, its operation effect, and a method of removing the second inserted member 330 from the fixing pins 301 and releasing the fixation of the substrate box to the movable base portion. Since these are the same as those in the fifth embodiment, detailed description thereof is omitted.

  In order to remove the first inserted member 310 from the tip side portion of the fixing pin 301, the fixing pin 301 is relatively rotated about the axis with respect to the first inserted member 310 on the other side (counterclockwise in FIG. 49). ) To rotate from the position indicated by the solid line to the position indicated by the phantom line in FIG. 49 so that the positions of the claw portion 304b of the front-end side locking claw 304 and the slit 381 coincide with each other, Is opposed to the front end surface 316a of the first locking portion 316.

  And the fixed pin 301 is urged | biased to an axial direction with this rotation angle position, and is moved to a removal direction. Accordingly, the claw portion 304b of the front end side locking claw 304 can be passed through the slit 381, and the front end side portion of the fixing pin 301 can be removed from the first insertion hole 313 of the first inserted member 310. The first inserted member 310 can be removed from the tip side portion of the fixing pin 301.

  Therefore, compared to the fifth embodiment described above, when the first inserted member 310 is removed from the tip side portion of the fixing pin 301, the claw portions 304b of the tip side locking claws 304 are moved closer to each other. It is not necessary to bend and bend the arm portion 305a, and it can be easily removed. Therefore, the fixing pin 301 can be removed more easily.

(Seventh embodiment)
Next, a seventh embodiment will be described below based on 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. 50A 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. 50, 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 with respect 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 sixth 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 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 the first member and the second member, and if the two members are coupled and separated by sliding relative to each other, Any thing is acceptable.

  In each of the above-described embodiments, the configuration in which the first insertion member 310 is detachably provided on the movable base portion 203 has been described. However, the present invention is not limited to this configuration mode. For example, the first inserted member 310 may be formed integrally with the bottom plate portion 261 of the movable base portion 203 so as to be removed from the bottom plate portion 261 by cutting a previously cut portion. Good.

  In each of the above-described embodiments, the case where both the first inserted member 310 and the second inserted member 330 are separated when the fixing pin 301 is removed has been described. However, the present invention is limited to this configuration. is not. For example, one of the first inserted member 310 and the second inserted member 330 may be separated so that the fixing pin 301 can be rotated relative to the second inserted member 330.

  In addition, the fixed pin 301 is configured such that, when the substrate box 102 is fixed to the movable base portion 203, the distal end portion of the fixed pin 301 is covered with the fitting portion 321 and cannot be directly touched. It is not an essential requirement that the tip side portion is covered, but it may be exposed and directly touched.
