A tray side binding hole 655 is provided at a position corresponding to the cover side binding hole 575 at the tip of the tray side tongue-like piece 651. The tray side binding hole 655 has a width of about 2 mm in the X-axis direction and a width of about 8 mm in the Y-axis direction. While maintaining the strength of the periphery of the cover-side binding hole 575 and the strength of the periphery of the tray-side binding hole 655, the substrate case 40 is greatly expanded in the X-axis direction so that it does not unnecessarily protrude outward (X2 direction). It is designed to prevent this.

  The binding band 92 is stored inside the tray member 60 so as to be along one end edge portion 66. When the control board 30 is inspected, both the second and third caulking mechanisms indicated by “F” in FIG. 7 are used. The second caulking mechanism is provided at one end edge portion 66 of the tray member 60. Since the tray member 60 has translucency as described above, the binding band provided along the end edge portion 66 is provided. 92 can be easily visually recognized, and the relationship between the third caulking mechanism and the binding band 92 can be easily recognized.

  The binding band 92 has a thickness of about 1 mm, a width of about 5 mm, and a total length of about 115 mm. The proximal end portion of the binding band 92 has an elongated hole through which the binding band 92 passes, and a locking groove is provided on the inner peripheral surface of the elongated hole. Locked grooves that are respectively locked to the locking grooves in the direction are formed continuously.

  The accommodating portion 93 of the binding band 92 is formed at the end edge portion 66 of the tray member 60. The accommodating portion 93 has a holding wall 931 having a width in the X-axis direction of about 10 mm, a wall thickness of about 2 mm (thickness in the Y-axis direction), and a height in the Z-axis direction of about 8 mm. is doing. Three holding walls 931 are provided along the edge portion 66. In order to secure the height of the holding wall 931 in the Z-axis direction, the end edge 58 is higher than the other peripheral edge 501 in the direction of about 5 mm Z2. Each holding wall 931 has a holding groove 932 having a width in the X-axis direction of about 1 mm and a depth in the Z-axis direction of about 5 mm. A binding band 92 is fitted in each holding groove 932.

  In order to constrain the substrate case 40 to the base member 70, as shown in FIGS. 6 and 7, the cover side binding hole 575, the tray side binding hole 655, and the base side binding hole 755 with the centers of the holes aligned are provided. By passing the binding band 92, the cover-side tongue-like piece 574 and the tray-side tongue-like piece 651 are fixed to the base-side tongue-like piece 751. The binding band 92 prevents the substrate case 40 from moving in the X2 direction and prevents it from moving in the Z2 direction.

(Sealing mechanism)
Next, a sealing mechanism is demonstrated with reference to FIGS. 5-7, FIG. 21, and FIG. 21A is a perspective view of the cap member in a separated state, FIG. 21B is a perspective view of the IC tag in a cut state, and FIG. 29 is a cross-sectional view of the IC tag 90 and the cap member 95 broken by a horizontal plane. is there.

  The sealing mechanism includes a cover-side protruding piece 591, a tray-side protruding piece 671, and an IC tag 90. The cover-side protruding piece 591 is provided so as to protrude from one end edge portion 58 of the cover member 50 in the X-axis direction.

  The cover-side projecting piece 591 has a cover-side flat portion 592 configured from a plane orthogonal to the Z-axis direction (front and back direction). The cover-side flat portion 592 is formed in a substantially rectangular shape, and has a width of about 24 mm in the X-axis direction and a width of about 65 mm in the Y-axis direction. In addition, the tray-side protruding piece 671 is provided so as to protrude from one end edge portion 66 of the tray member 60 in the X-axis direction. The tray-side protruding piece 671 has a tray-side flat portion 672 configured from a plane orthogonal to the Z-axis direction. The tray-side flat portion 672 is formed in a substantially rectangular shape, and has a width of about 20 mm in the X-axis direction and a width of about 65 mm in the Y-axis direction.

  When the engaging part 631 is engaged with the engaged part 521, the tray side flat part 672 is formed so as to be smoothly connected to the cover side flat part 592. The tray-side flat portion 672 is in contact with the cover-side flat portion 592 or close to it with a slight gap. The IC tag 90 is formed in a sheet shape, and is pasted so as to span from one of the cover-side flat portion 592 and the tray-side flat portion 672 to the other. An IC tag 90 represented by hatching is shown in FIG. It is not necessary to attach the sheet-like IC tag 90 only to the front side surfaces of the cover-side flat surface portion 592 and the tray-side flat surface portion 672 and to route the cover-side IC tag 90 to the back-side surface of the cover-side flat surface portion 592 and the tray-side flat surface portion 672. Therefore, workability can be facilitated.

  By providing the IC tag 90, security can be enhanced. Further, when removing the cover member 50 from the tray member 60, it is necessary to break the IC tag 90 covering the screw member 94 that fixes the cover member 50 and the tray member 60. Therefore, it becomes possible to leave a history of opening the substrate case 40 by the damaged IC tag 90. Further, the cover side flat portion 592 and the tray side flat portion 672, which are dedicated spaces for attaching the IC tag 90, are provided on the cover member 50 and the tray member 60, and are formed in a flat shape, so that the IC tag 90 is flattened. Since it could be pasted, the IC tag 90 can be made difficult to break.

  The tray side plane portion 672 has a thickness in the Z-axis direction of about 2 mm. Both side edge portions formed along the X-axis direction of the tray side flat portion 672 are formed in a flange shape having a height of about 5 mm in the Z-axis direction (front and back direction). The side edge part formed in the flange shape has a step part 676 formed by about 1 mm higher in the Z2 direction (front direction) than the front side surface of the tray side flat part 672.

  The back side surface of the tray side flat surface portion 672 has a cylindrical portion 674 at a position of about 9 mm in the X-axis direction from one end edge portion 66 of the tray member 60. The cylindrical portion 674 has a height of about 2.0 mm, an outer diameter of about 6 mm, and an inner diameter of about 3 mm in the Z1 direction from the back side surface of the tray-side flat portion 672. An inner diameter portion of the cylindrical portion 674 is a through hole 675.

(Cover side protrusion etc.)
Next, details of the cover-side protruding piece 591 and assembly of the cover-side protruding piece 591 and the tray-side protruding piece 671 will be described.

  The extension piece 593 has a cylindrical portion 595 and a rib 595b. A screw hole 595a is formed in the cylindrical portion 595 along the central axis. The cylindrical portion 595 has an outer shape of about 6 mm and a height of 13 mm in the Z2 direction from the position of the extension piece 593. A rib 595b extends from the cylindrical portion 595 to a side wall 597b and an end wall 597d described later. The rib 595b has a height of about 13 mm in the Z2 direction, and reinforces the cylindrical portion 595. The cylindrical portion 595 and the rib 595b are shown in FIG.

  The screw hole 595a has a groove diameter of about 3 mm. When the engaging portion 631 is engaged with the engaged portion 521, the cylindrical portion 595 overlaps the cylindrical portion 674 in the Z-axis direction, and the screw hole 595a matches the through hole 675. The screw member 94 passes through the through hole 675, is screwed into the screw hole 595a, and the cover-side protruding piece 591 and the tray-side protruding piece 671 are assembled together. The X2 direction of the cover member 50 with respect to the tray member 60 (left in FIG. 29) Direction) movement. Thereby, the screw hole 595a, the through hole 675, the screw member 94, and the like have a function as a caulking mechanism. The head of the screw member 94 is covered with an IC tag 90 which will be described later. Since the head of the screw member 94 is covered with the IC tag 90, there is no need to separately provide a part for covering the head of the screw member 94.

(Cover side protrusion, extension piece)
Next, details of the shapes of the cover-side protruding piece 591 and the extension piece 593 will be described. The cover-side protruding piece 591 is formed in a substantially rectangular parallelepiped box shape whose opening is directed in the Z1 direction (back direction). The cover-side protruding piece 591 has a cover-side flat portion 592 that is a bottom surface portion of the box, and is an outer peripheral wall that is formed along side walls 596a and 596b formed along the X axis, and along the Y axis. It has the end surface walls 596c and 596d formed. Each of the walls 596a to 596c constituting the outer peripheral wall is formed so as to come into contact with the sub-base seat surface portion 781.

  On the other hand, the extension piece 593 is formed in a substantially rectangular parallelepiped small box shape with the opening directed in the Z1 direction (back direction). The extension piece 593 has a bottom surface portion 597a of a box having a width of about 16 mm in the X-axis direction and a width of about 33 mm in the Y-axis direction, and side walls 597b, 597c formed along the X-axis, and The peripheral wall 597 is composed of end walls 597d and 597e formed along the Y axis. The end wall 597e constitutes a part of the end face wall 596c.

  As described above, by directing the opening of the extension piece 593 formed in the box shape in the Z1 direction, the walls 597c to 597e constituting the peripheral wall are brought into contact with the sub-base seat surface portion 781, and the cover-side protruding piece 591 is provided. In addition, the extension piece 593 can be stably moved in the X-axis direction.

  The bottom surface portion 597a is formed so that the cover-side flat surface portion 592 is smoothly connected to the tray-side flat surface portion 672 by making it about 4 mm lower than the position of the cover-side flat surface portion 592 in the Z-axis direction.

  One reason that the tray-side protruding piece 671 is provided on the right edge portion 66 of the tray member 60 and the cover-side protruding piece 591 is provided on the right edge portion 58 of the cover member 50 is that the cover member 50 is attached to the tray member 60. When the cover member 50 is assembled to the tray member 60 relative to the X1 direction (rightward), the gap between the end edge 58 of the cover member 50 and the tray-side protruding piece 671 (extension piece 673). Is used as a moving space for the tray-side flat portion 672 of the tray-side protruding piece 671 to simplify the configuration of the cover-side protruding piece 591 and the tray-side protruding piece 671, and the cover member 50 is replaced with the tray member 60. This is for simplifying the operation of assembling the cover member 50 to the tray member 60 relative to the right direction.

  As described above, when the cover member 50 is moved relative to the tray member 60 in the X1 direction, the tray-side flat portion 672 of the tray-side protruding piece 671 moves in the upper space of the extension piece 593 and the cover-side protruding piece 591 is moved. It is possible to form an XY plane for attaching the IC tag 90 to the two flat portions by contacting or approaching the cover-side flat portion 592.

  On the other hand, if the tray member 60 is assembled to the cover member 50 by moving the tray member 60 relative to the cover member 50 in the X1 direction (right direction), the tray-side protruding piece 671 is attached to the tray member 60. When the cover-side protruding piece 591 is provided on the left-side end edge portion 58 of the cover member 50, the tray-side protruding piece 671 is passed above the cover-side protruding piece 591. And the configuration becomes complicated. For example, a cover member is used to form an XY plane between the tray-side flat portion 672 of the tray-side protruding piece 671 and the cover-side flat portion 592 of the cover-side protruding piece 591 after passing the tray-side protruding piece 671. 50 and the tray member 60 need to be moved relative to each other in the Z-axis direction (front and back direction), the operation of assembling the cover member 50 to the tray member 60 becomes complicated, and inspection work and the like are difficult.

(IC tag)
Next, the IC tag 90 and the stepped portion will be described. The peripheral edge portion of the tray side flat surface portion 672 has a step portion 676 formed by about 1 mm higher in the Z2 direction (front direction) than the position of the tray side flat surface portion 672. The step portion 594 and the step portion 676 both having a height of about 1 mm surround the IC tag 90 having a predetermined thickness attached to the cover-side flat portion 592 and the tray-side flat portion 672, and The IC tag 90 is formed to be higher than the thickness. During assembly work of the substrate case 40 and inspection work of the control board 30, the IC tag 90 is peeled off without being touched by the step 594 and the step 676, and the operator touching the periphery of the IC tag 90. It becomes possible to prevent.

(Assembling the cap member)
Next, assembly of the cap member 95 will be described with reference to FIGS. 27, 29, and 30. FIG. A locking hole 58 a for preventing the cap member 95 from coming off in the X2 direction is formed in the end edge portion 58 of the cover member 50.

  The cap member 95 is fitted into the cover-side protruding piece 591 and the tray-side protruding piece 671 from the X-axis direction. The cap member 95 is formed in a box lid shape. The cap member 95 has a top surface portion 951 formed so as to face in the Z-axis direction, and a peripheral wall portion 952 that covers the inside of the box lid from three directions except for one direction. The peripheral wall portion 952 has a pair of side wall portions 953 and 954 formed along the X axis, and an end wall portion 955 formed along the Y axis direction.

The top surface portion 951 of the cap member 95 has a locking projection 958 having an arrow shape in the X2 direction from the edge facing the end edge portion 58 of the cover member 50. The basic shape of the locking projection 958 is the same as the first arrow piece 815 and the second arrow piece 825 of the caulking member 80, and has a Z-axis length of about 3 mm. It differs from the 1st arrow piece 815 and the 2nd arrow piece 825 which have the height of an axial direction. Since the locking protrusion 958 is fitted into the locking hole 58a on the cover member 50 side, the cap member 95 is prevented from coming off in the X2 direction.
A long hole 957 is formed in the end wall portion 955 of the cap member 95 with the Y-axis direction as the longitudinal direction and the Z-axis direction as the short direction. A tip edge 959 that is bent in the X1 direction is provided at the wall end of the end wall 955. The edge of the elongated hole 957 on the Z1 direction side and the leading edge 959 are formed continuously.

  One of both edge portions 75 and 76 formed along the Y-axis on the peripheral edge 72 of the base member 70, when the fitting portion 737 is fitted to the fitted portion 637, the cap member 95 is A fitting recess 785 is fitted into the cap member 95 so as not to be linearly separated in the Z2 direction (front direction). The attaching direction of the cap member 95 is the X2 direction, which is the same as the caulking direction of the caulking member 80, and the attaching operation of the cap member 95 can be facilitated.

(Operation protrusion)
Next, an operation protrusion 756 for preventing the substrate case 40 from moving in the X2 direction will be described with reference to FIGS.

  The end edge portion 75 of the base member 70 has an operation protrusion 756 formed so as to protrude in the X2 direction. The operation protrusion 756 includes a flexible piece 757, an intermediate piece 758, and an operation piece 759 in order in the X2 direction. The intermediate piece 758 is formed to be approximately 2 mm higher than the flexible piece 757 in the Z2 direction. A step portion 758 a is formed at the end of the intermediate piece 758 (end on the flexible piece 757 side). The operation piece 759 has a length in the Z-axis direction of about 12 mm, and is formed to be about 2 mm higher than the intermediate piece 758 in the Z2 direction. A stepped portion 759a is formed at the end of the operation piece 759 (the end on the intermediate piece 758 side).

  The edge portion 65 of the tray member 60 on the intermediate piece 758 is shown in FIG. In FIG. 10, the intermediate piece 758 raises the edge 65 of the tray member 60 by about 2 mm in the Z2 direction, and lifts the entire tray member 60 from the base surface portion 71 of the base member 70 by about 2 mm in the Z2 direction. The fitted portion 637 is not fitted to the lower end of the entering / exiting groove 738 of the fitting portion 737, and the fitting portion 737 is prevented from entering the locking groove 739. During the assembling work, the fitted portion 637 does not inadvertently enter the locking groove 739, and the operator can move to the next stage while checking each stage, thereby preventing erroneous work. it can.

  When the end edge portion 65 of the tray member 60 is dropped from the intermediate piece portion 758 to the flexible piece portion 757, the end edge portion 65 of the tray member 60 is lowered by about 2 mm in the Z1 direction, and the entire tray member 60 is moved. Since the base member 70 is lowered by about 2 mm in the direction of the base surface portion 71 (Z1 direction), the fitted portion 637 is allowed to enter the locking groove 739. During the assembling work, the operator can move to the next stage in which the fitted portion 637 enters the locking groove 739 by bending the flexible piece 757, thereby preventing erroneous work. it can. Further, the end edge portion 65 of the tray member 60 abuts on the stepped portion 758a, thereby preventing the fitted portion 637 from coming out of the locking groove 739, and the substrate case 40 (tray member 60) in the X2 direction. Stop movement. The edge 65 of the tray member 60 on the flexible piece 757 is shown in FIG.

  In order to move the substrate case 40 (tray member 60) in the X2 direction, the operation piece portion 759 is lowered in the Z1 direction, the end edge portion 65 of the tray member 60 is removed from the step portion 758a, and the fitted portion 637 is locked. The board case 40 (tray member 60) is allowed to move in the X2 direction while allowing the substrate case 40 (the tray member 60) to move out from the groove 739.

(Board case assembly work)
Next, an operation for assembling the substrate case 40 to the machine main body 11 and an operation for inspecting the control board will be described.

(Assembly work of cover member and tray member)
First, an operation for assembling the cover member 50 and the tray member 60 will be described.

  The cover member 50 is moved relative to the tray member 60 in the Z1 direction so that the side edge portions 52 and 56 of the cover member 50 are fitted into the guide groove portions 630 of the tray member 60 and between the adjacent engaging portions 631. The engaged portions 521 and 561 are inserted (state shown in FIG. 13A). With the guide groove portion 630, the cover member 50 can be guided in the X1 direction with respect to the tray member 60.

Status). This prevents the cover member 50 from moving linearly in the Z2 direction with respect to the tray member 60.

(Use of second caulking mechanism “A”)
Next, the second caulking mechanism indicated by “A” in FIG. 7 is used. In the two sets of engagement states, when the caulking hook 88 is inserted into the small diameter cylindrical portion 892 from the outside in the X2 direction with the hook head portions 884 and 885 at the head, the distance between them is reduced against the restoring force. The hook first arrow piece 881 and the hook second arrow piece 882 enter the receiving recess 69 and spread by a restoring force, engage with the stepped portion 893, and hook hook lid on the peripheral portion of the tube inlet portion 599. The member 886 abuts (the caulking state of the second caulking mechanism). This prevents the cover member 50 from moving relative to the tray member 60 in the X2 direction.

(Use of sealing mechanism)
Next, a sealing mechanism is used. In the sealing mechanism, the cover-side flat portion 592 and the tray-side flat portion 672 are smoothly connected to form an XY plane. The screw hole 595a of the cover side protruding piece 591 and the through hole 675 of the tray side protruding piece 671 coincide. The screw member 94 is screwed into the screw hole 595a and the through hole 675. The IC tag 90 is affixed to the cover-side flat portion 592 and the tray-side flat portion 672 (state shown in FIG. 29). The locking protrusion 958 of the cap member 95 is fitted in the locking hole 58a on the cover member 50 side. Further, the tip end portion of the cover-side protruding piece 591 is fitted into the elongated hole 957 of the cap member 95. (State shown in FIG. 29). Thereby, the cap member 95 is restrained in a state where the IC tag 90 is covered from the Z1 direction.

  In the operation of assembling the cover member 50 and the tray member 60, the second caulking mechanism indicated by “A” in FIG. 7 is used, the first caulking mechanism indicated by “B” in FIG. 7 and the first caulking mechanism indicated by “F”. Do not use the two caulking mechanism.

  Further, the third caulking mechanism indicated by “C” in FIG. 7 is not used. In the third caulking mechanism, the tray-side tongue-like piece 651 passes through the communication hole 571 of the cover member 50 and overlaps with the cover-side tongue-like piece 574, and the center of each hole of the cover-side binding hole 575 and the tray-side binding hole 655 coincides. To do. However, the binding-side band 92 does not bind the cover-side tongue-like piece 574 and the tray-side tongue-like piece 651. As described above, the operation of assembling the cover member 50 and the tray member 60 is completed, and the control board 30 can be sealed in the board case 40.

(Board case assembly work)
Next, an operation for assembling the substrate case 40 to the machine main body 11 will be described.

The sub base member 78 is assembled to the base member 70 in advance. The base member 70 is attached to a predetermined position on the rear wall 11a of the machine body 11.
With the ceiling 51 of the cover member 50 facing forward, the substrate case 40 is opposed to the base member 70, the substrate case 40 is moved relative to the base member 70 in the Z1 direction, and the fitted portion 637 of the tray member 60 is moved. , 647 are inserted into the access groove 738 of the base member 70. The other edge 65 of the tray member 60 abuts against the intermediate piece 758 of the operation protrusion 756 (the state shown in FIG. 10A), and the mated portions 637 and 647 and the base member 70 are taken in and out. A gap of about 2 mm is formed between the groove 738 and the groove bottom. When the operation protrusion 756 is displaced in the Z1 direction against the elastic force of the flexible piece 757 (the state shown in FIG. 10B), the fitted portions 637 and 647 are the base member 70. It reaches the groove bottom of the entrance / exit groove 738 (the state shown in FIG. 12A), faces the groove opening of the lock groove 739 of the base member 70 in the X-axis direction, and the substrate case 40 is X1 with respect to the base member 70. It becomes possible to move relative to the direction. At this time, the leading edge 959 of the end wall portion 955 of the cap member 95 is separated in the Z2 direction from the fitting recess 785 of the base member 70 and is not fitted in the fitting recess 785 (the state shown in FIG. 30). . During the assembling work, the operator can move to the next stage enabling the movement of the substrate case 40 in the X1 direction by bending the flexible piece 757, thereby preventing erroneous work. .

Further, the substrate case 40 is moved relative to the base member 70 in the X1 direction, and the fitted portions 637 and 647 of the tray member 60 are inserted into the locking grooves 739 of the base member 70 (3 shown in FIG. 9B). Set engagement state). This prevents the substrate case 40 from moving relative to the base member 70 in the Z2 direction. Back and forth, the other edge 65 of the tray member 60 is disengaged from the intermediate piece 758 of the operation protrusion 756 (the state shown in FIG. 10C), and the flexible piece 757 is restored by its elastic force. And the other edge part 65 fits in the step part 758a between the flexible piece part 757 and the intermediate piece part 758 (state shown in FIG.10 (d)).
In the three sets of engagement states, the front end portions 583 and 663 of the first and second crimping portions 581 and 661 are fitted into the fitting groove 792 of the protection member 79. A gap S <b> 2 is formed between the first side wall 587 of the tip portion 583 and the second side wall 667 of the tip portion 663. The gap S2 communicates with the outside (X1 direction) through a communication hole 794 formed in the standing wall portion 793 of the protection member 79.

(Use of first caulking mechanism)
Next, the first caulking mechanism indicated by “B” in FIG. 7 is used. The leading portions 814 and 824 of the caulking member 80 are advanced to be inserted into the communication hole 794 and the insertion groove S1. When passing through the communication hole 794 and the insertion groove S1, the first arrow piece 815 of the first caulking member 81 and the second arrow piece 825 of the second caulking portion 661 narrow against the restoring force, and the communication hole 794 After passing through the insertion groove S1, the first arrow piece 815 of the first caulking member 81 spreads by the restoring force, and the first side wall 587 of the first caulking portion 581 is caulked together with the standing wall portion 793. The second arrow piece 825 of the second caulking portion 661 caulks the second side wall 667 of the second caulking portion 661 together with the standing wall portion 793. The substrate case 40 (the two sets of the cover member 50 and the tray member 60 in the engaged state) is prevented from moving relative to the base member 70 in the X2 direction.
When using the first caulking mechanism, it is only necessary to insert the caulking member 80 into the communication hole 794 and the insertion groove S1, so that a dedicated jig is not required and workability can be improved. Further, by inserting the caulking member 80, the outer shape of the substrate case 40 has a convex portion, so that the caulking state of the first caulking mechanism can be easily determined.

  In the sealing mechanism, when the substrate case 40 is moved relative to the base member 70 in the X1 direction to be in the three sets of engagement states, the leading edge 959 of the end wall portion 955 of the cap member 95 is formed in the elongated hole 957. Together with the leading edge 591a of the cover-side protruding piece 591 that has passed through, it is fitted into the fitting recess 785 of the base member 70 (state shown in FIG. 29). This prevents the cap member 95 from moving relative to the base member 70 in the Z2 direction.

(Control board inspection work)

In the removal of the first caulking mechanism indicated by “B” in FIG. 7, first, the connecting member 83 is cut to release the covering by the covering member 84 and to release the caulking by the caulking member 80. When the connecting member 83 is cut, the connecting relationship between the caulking member 80 and the covering member 84 is cut off, the restraint by the caulking member 80 on the covering member 84 is released, and the covering member 84 is connected to the first caulking portion 581 and the second covered portion. The base end portions 582 and 662 of the caulking portion 661 can be moved from a predetermined position covering the outside. The covering member 84 is removed from the predetermined position, and the base end portions 582 and 662 of the first and second caulking portions 581 and 661 are cut together. As a result, from the three sets of engagement states, the cover member 50 and the tray member 60 are in two sets of engagement states.

  When the substrate case 40 is moved in the X2 direction with respect to the base member 70, the flexible piece 757 is bent in the Z1 direction against its elastic force, and between the flexible piece 757 and the intermediate piece 758. The other edge portion 65 is removed from the step portion 758a (state shown in FIG. 10C). At this time, the leading edge 959 of the end wall portion 955 of the cap member 95 is disengaged from the fitting recess 785 of the base member 70 (state shown in FIG. 30).

  The substrate case 40 is moved in the X2 direction with respect to the base member 70, and the fitted portions 637 and 647 of the tray member 60 are removed from the locking groove 739 of the base member 70 (state shown in FIG. 9A). 40 is moved in the Z2 direction (near side) with respect to the base member 70, the fitted portions 637 and 647 are removed from the access grooves 738 of the base member 70, and the substrate case 40 is removed from the base member 70.

(Removal of second caulking mechanism “A” during inspection work)
In the removal of the second caulking mechanism indicated by “A” in FIG. 7, the outer cylindrical portion 598 is separated from the end edge portion 58 of the cover member 50, and the hook of the caulking hook 88 accommodated in the accommodating recess 69 on the tray member 60 side is obtained. The connection relation between the first arrow piece 881 for hook and the second arrow piece 882 for hook and the lid member 886 for hook is cut off. Thereby, the restraint of the second caulking mechanism that prevents the movement of the cover member 50 in the X2 direction with respect to the tray member 60 is released.

(Removal of sealing mechanism)
In removing the sealing mechanism, the locking projection 958 of the cap member 95 is removed from the locking hole 58a of the cover member 50. Thereby, the cap member 95 can be moved in the Z2 direction. The cap member 95 is removed from the IC tag 90, the IC tag 90 is peeled off from the cover side flat part 592 and the tray side flat part 672, and the screw member 94 is removed from the screw hole 595 a and the through hole 675. Thereby, the cover member 50 can be moved in the X2 direction with respect to the tray member 60.

  The cover member 50 is moved in the X2 direction with respect to the tray member 60, and the engaging portion 631 is positioned between the adjacent engaged portions 521 (state shown in FIG. 13A). At this time, the tray-side tongue-like piece 651 of the tray member 60 comes out from the communication hole 571 of the cover member 50. Further, the cover member 50 is moved with respect to the tray member 60 in the Z2 direction. Accordingly, the cover member 50 can be removed from the tray member 60, and the control substrate 30 in the substrate case 40 can be inspected.

(Use of second caulking mechanism “F” and third caulking mechanism “C”)
After the inspection of the control board 30 is completed, the cover member 50 is assembled to the tray member 60, the second caulking mechanism indicated by “F” is used, the board case 40 is further assembled to the machine body 11, and “C”. A third caulking mechanism shown in FIG.

  After the inspection or the like of the control board 30 is completed, the cover member 50 is assembled to the tray member 60. Since the assembly work is the same as the work of assembling the cover member 50 to the tray member 60 before the inspection work of the control board 30 described above, the description thereof is omitted.

(Use of second caulking mechanism “F”)
Next, the second caulking mechanism indicated by “F” in FIG. 7 is used. The use of the second caulking mechanism “F” is similar to the above-described use of the second caulking mechanism “A”, and the caulking hook 88 is attached to the small diameter cylindrical portion 892 from the outside in the X2 direction by using the hook head portions 884, 885. When inserted at the head, the first arrow piece 881 for hook and the second arrow piece 882 for hook, which are spaced from each other against the restoring force, enter the receiving recess 69 and spread by the restoring force, and the step 893 And the hook lid member 886 is brought into contact with the peripheral edge portion of the tube inlet portion 599 (the caulking state of the second caulking mechanism). This prevents the cover member 50 from moving relative to the tray member 60 in the X2 direction.

  Next, the substrate case 40 is assembled to the machine main body 11. The assembly work is the same as the work of assembling the substrate case 40 to the machine main body 11 before the inspection work of the control board 30 described above, and the description thereof is omitted.

(Use of third caulking mechanism “C”)
Next, the third caulking mechanism indicated by “C” in FIG. 7 is used. By assembling the substrate case 40 to the machine body 11, the cover-side tongue-like piece 574, the tray-side tongue-like piece 651 and the base-side tongue-like piece 751 are overlapped, and the cover-side binding hole 575, the tray-side binding hole 655, and The center of each hole of the base side bundling hole 755 coincides (three sets of engagement states). The cover-side tongue-like piece 574, the tray-side tongue-like piece 651, and the base-side tongue-like piece 751 are bundled by the binding band 92 passed through each hole. Accordingly, the substrate case 40 is prevented from moving in the X2 direction with respect to the base member 70, and the substrate case 40 can be assembled to the machine body 11 via the base member 70.

(Diversion of caulking member, diversion of board case)
Next, diversion of the caulking member 80 and diversion of the substrate case by Nikoichi will be described. First, diversion of the caulking member 80 will be described. In the caulking state of the first caulking mechanism, the first arrow piece 815 of the caulking member 80 caulks the first side wall 587 of the first caulking portion 581 together with the standing wall portion 793, and the second arrow piece 825 of the second caulking portion 661. However, the second side wall 667 is crimped together with the standing wall portion 793. When the caulking member 80 is diverted in the caulking state of the first caulking mechanism, the protection member 79 is removed, and further, the tip portions 583 and 663 of the first caulking portion 581 and the second caulking portion 661 are removed. However, it is necessary to cancel the caulking relationship between these members and the caulking member 80. At this time, the standing wall portion 793 and the first side wall 587 must be excluded without damaging the first arrow piece 815. Further, the standing wall portion 793 and the second side wall 667 must be excluded without damaging the second arrow piece 825. As described above, it is extremely difficult to transfer the caulking member 80 in the caulking state of the first caulking mechanism.

  Next, diversion of the substrate case by Nikoichi will be described. In the caulking state of the first caulking mechanism, the protection member 79 is removed, and further, the caulking member 80 is removed, and each of the members, the first caulking portion 581 and the second caulking portion 661 described above. It is also extremely difficult to cancel the relationship with the tip portions 583 and 663. That is, the standing wall portion 793 and the first arrow piece 815 must be excluded without damaging the first side wall 587. Further, the standing wall portion 793 and the second arrow piece 825 must be excluded without damaging the second side wall 667. As described above, it is difficult to illegally obtain the cover member 50 and the tray member 60 in the caulking state of the first caulking mechanism, and it is extremely difficult to divert the cover member 50 and the tray member 60 to the substrate case 40 (Nikoichi). Become.

  Further, for example, the base end portion of the first caulking portion 581 in an attempt to illegally open the substrate case 40 without unauthorized access to the first caulking portion 581 or the first caulking member 81 or the like. When the cutting portion 582 is cut and the leading end portion 663 of the second crimping portion 661 is to be extracted from the fitting groove 792 of the protective member 79, the leading end portion 663 of the second crimping portion 661 is moved by the second crimping member 82. Since it is caulked together with the standing wall portion 793, it is difficult to extract from the fitting groove 792. Further, when the base end portion 662 of the second caulking portion 661 is cut and the distal end portion 583 of the first caulking portion 581 is to be extracted from the fitting groove 792 of the protective member 79, the first caulking member Since 81 has crimped the front-end | tip part 583 of the 1st to-be-crimped part 581 with the standing wall part 793, it becomes difficult to extract from the fitting groove | channel 792, and the cover member 50 and the tray member 60 are diverted to the board | substrate case 40. (Nikoichi) becomes extremely difficult.

  Further, even if one of the base end portions 582 and 662 of the first caulking portion 581 or the second caulking portion 661 is cut, the first caulking member 81 and the second caulking member 82 that are integrally formed are cut. However, in order to maintain the crimped state of the front end portions 583 and 663 of the first crimped portion 581 and the second crimped portion 661 together with the standing wall portion 793, so to speak, the crimping member 80, the first crimped portion 581 and the first crimped portion 581 2 Since the front end portions 583 and 663 of the caulking portion 661 are integrated and remain in the fitting groove 792, the front end portions 583 and 663 of the first caulking portion 581 or the second caulking portion 661 are attached. It becomes difficult to extract from the fitting groove 792, and unauthorized acquisition of the cover member 50 and the tray member 60 becomes difficult. Also from this point, it is very difficult to divert the cover member 50 and the tray member 60 to the substrate case 40 (Nikoichi).

  Next, confirmation of the caulking state will be described. As described above, since the outer shape of the substrate case 40 has the convex portion by the first caulking mechanism in the caulking state, the caulking state can be easily determined. When the first caulking mechanism is removed, the convex portion is eliminated, so that the outer shape of the substrate case 40 is greatly changed. Therefore, the unauthorized opening of the substrate case 40 can be easily visually confirmed, and the substrate case 40 is caulked. Can be easily determined.

  Next, advantages of providing the lid member 85 will be described. By cutting the connecting member 83, the first caulking member 81, the second caulking member 82, the lid member 85, and the covering member 84 are disconnected. Even at this time, the first caulking member 81, the second caulking member 82, and the lid member 85 maintain the state in which the standing wall portion 793 is sandwiched from both directions with respect to the X-axis direction. The cutting tool or the like is passed through the communication hole 794 and the like to the first caulking member 81, the second caulking member 82, the first caulking portion 581, and the second caulking portion 661. It becomes difficult to access. Thereby, when the substrate case 40 is tampered with, the connection member 83 must be cut, and the base end portions 582 and 662 of the first and second caulking portions 581 and 661 must be cut, A trace of cutting is left, and it is possible to easily determine the caulking state of the first caulking mechanism.

  Next, advantages of providing the first shielding member 871 and the second shielding member 872 will be described. Since the first plate-like portion 584 and the second plate-like portion 664 (see FIG. 26) are covered from the outside by the first shielding member 871, when the substrate case 40 is tampered with, the cutting tool or the like is used as the first plate-like portion. Since the part 584 and the second plate-like part 664 cannot be accessed and the first plate-like part 584 and the second plate-like part 664 cannot be cut, the connection member 83 can only be cut, leaving a trace of cutting. It becomes. Similarly, since the front side edge portions 584b and 664b of the first plate-like portion 584 and the second plate-like portion 664 are covered from the outside by the second shielding member 872, when the substrate case 40 is illegally opened, a cutting tool is used. Etc. cannot access the first plate-like portion 584 and the second plate-like portion 664, and the first plate-like portion 584 and the second plate-like portion 664 cannot be cut. A trace of cutting will be left.

  Next, advantages of providing the rib portion 798 will be described. Since the rib portion 798 is provided in the region of the base member 70 corresponding to the position of the opening 791 of the protection member 79, it is difficult to destroy the region, and the cutting tool or the like is passed through the opening 791. It becomes difficult to access inside.

  Next, advantages of providing the overhang portion 797 will be described. Since the overhanging portion 797 covers the entire circumference of the lid member 85 from the outside, even if the lid member 85 is separated from the standing wall portion 793 due to a dimensional accuracy error of the lid member 85 and an assembly accuracy error thereof, It is possible to maintain the state where the overhanging portion 797 covers the entire circumference of the lid member 85 from the outside, and to prevent the communication hole 794 of the standing wall portion 793 from being exposed to the outside.

  In the embodiment, the shapes of the caulking member 80 and the caulking portion may be reversed. That is, the leading portions 814 and 824 of the first caulking member 81 and the second caulking member 82 are formed in a substantially groove-shaped cross-sectional shape, and the tip portions 581 and 661 of the first caulking portion 581 and the second caulking portion 661 are formed. May be formed in a substantially arrow cross-sectional shape.

  In addition, the 1st crimping mechanism which concerns on embodiment showed the structure which crimps each other's member in a 3rd aspect under 3 sets of engagement states, but under 2 sets of engagement states, The structure may be crimped in the first or second mode. Also in this case, the connecting member 83 is formed so as to be severable for releasing the covering by the covering member 84 and releasing the caulking by the caulking member 80.

  In the embodiment, the protective member 79 provided on the sub-base member 78 may be provided on the caulking member 80. The protective member 79 having a substantially U-shaped cross-section with the opening directed in the Z1 direction is formed integrally with the caulking member 80. By cutting the connecting member 83, the connecting relationship between the caulking member 80 and the protecting member 79 and the covering member 84 is cut off. The covering by the covering member 84 can be released, and the base end portions 582 and 662 of the first and second caulking portions 581 and 661 are cut, so that the caulking by the caulking member 80 can be released.
