Description

[Technical Field]

[0001] FIELD OF THE INVENTION An embodiment of the present invention relates to a control panel. [Background technology]

[0002] Conventionally, control panels for power conversion equipment and the like house many control boards and electrical equipment inside their housings. Furthermore, the electrical components (equipment) housed inside the control panel housings must be removed from the control panel housings during inspection and maintenance.

[0003] However, if each supply unit is placed on the left and right side walls or the back of the housing's inner wall and is configured to be able to be pulled out individually, there is a possibility that although the supplies are placed along the side walls inside the housing, they may not be placed in a central position in the internal space away from the side walls.

[0004] If the density of the supplies is increased, work will have to be done in a small space inside the housing, which could reduce work efficiency, so in some cases it was necessary to select the appropriate supply from among the supplies and easily pull it out of the housing as needed. Furthermore, it is possible to arrange supplies at a high density, and at the same time, it is possible to accommodate flexible arrangement of supplies, such as changing the layout of the supply arrangement, in response to an increase or decrease in the number of parts of the supplies to be arranged.

[0009] The control panel of the first embodiment will be described below with reference to the drawings.

[0010] (First embodiment) Fig. 1 is a perspective view showing a control panel in an embodiment, Fig. 2 is a perspective view showing an equipment arrangement plate and a drawer mechanism of the control panel in an embodiment, and Fig. 3 is a perspective view showing an equipment arrangement plate and a drawer mechanism of the control panel in an embodiment.

[0011] Hereinafter, the X-axis, Y-axis, and Z-axis directions, which are perpendicular to each other in three-dimensional space, are directions parallel to each axis. For example, the left-right direction of the control panel 10 is parallel to the X-axis direction. The front-rear direction of the control panel 10 is parallel to the Y-axis direction. The positive direction of the Y-axis direction is the direction from the rear to the front of the control panel 10. The up-down direction and vertical direction of the control panel 10 are parallel to the Z-axis direction. The positive direction of the Z-axis direction is the direction from the bottom to the top of the control panel 10.

[0012] 1 to 3, a control panel 10 according to the embodiment is provided in, for example, power equipment, etc. The control panel 10 is a power distribution board, a distribution panel, a control panel, etc. that constitutes a power conversion device, a power supply device, a motor drive device, etc. The control panel 10 has a housing 11, a plurality of item placement plates 13, and a drawer mechanism 15. The housing 11 has a substantially rectangular parallelepiped outer shape. Almost the entire front surface 11f of the housing 11 is open. An opening 11a of the housing 11 is provided with an opening / closing door 12 that can be opened and closed. When the opening / closing door 12 is closed, the inside of the housing 11 is isolated from the outside.

[0013] The housing 11 has left and right side panels 11s, 11s, a bottom panel 11d, a back panel 11b, and a top panel 11u. The left and right side panels 11s, 11s, the bottom panel 11d, the back panel 11b, and the top panel 11u are connected to each other at their edges. A wiring inlet 11k is formed in the bottom panel 11d at a forward position close to the front surface 11f.

[0014] The equipment placement plate 13 is stored inside the housing 11. The equipment placement plate 13 is arranged parallel to the side panels 11s, 11s. The equipment placement plate 13 is arranged along the inside of the side panel 11s. The equipment placement plate 13 is arranged on the inside of each of the left and right side panels 11s. The right equipment placement plate (equipment placement plate) 13 is arranged on the inside surface of the right side panel (side panel) 11s. The left equipment placement plate (equipment placement plate) 13 is arranged on the inside surface of the left side panel (side panel) 11s. On both the right equipment placement plate 13 and the left equipment placement plate 13, equipment (not shown) is mounted and arranged on the side opposite the side facing the side panel 11s. The equipment includes control boards, electrical components, etc.

[0015] The right and left supply placement plates 13 each have a rectangular outline. The right and left supply placement plates 13 are each supported on the side panels 11s by a drawer mechanism 15. The right and left supply placement plates 13 are each divided into multiple pieces positioned above and below by a dividing line along the front-to-rear direction. The equipment placement board 13 of the embodiment is divided into two parts in the vertical direction relative to one side panel 11s. The equipment placement board 13 of the embodiment is divided into two parts in the vertical direction relative to the other side panel 11s.

[0016] The right supply placement plate 13 is divided into two in the vertical direction relative to the right side panel 11s. The two right supply placement plates 13 are arranged so as to cover almost the entire inner surface of the right side panel 11s. Each of the two right supply placement plates 13 has a Y-direction dimension that is almost the same as the depth direction (front-to-back direction) dimension of the right side panel 11s. The Z-direction dimensions of the two right supply placement plates 13 may be the same or different. The left supply placement plate 13 is divided into two in the vertical direction relative to the left panel 11s. The two left supply placement plates 13 are arranged so as to cover almost the entire inner surface of the left panel 11s. Each of the two left supply placement plates 13 has a Y-direction dimension that is almost the same as the depth (front-to-back) dimension of the left panel 11s. The Z-direction dimensions of the two left supply placement plates 13 may be the same or different.

[0017] In this way, the right and left equipment placement plates 13, which are parallel and opposed to each other, may have the same contour shape, so long as they are arranged along the left and right side panels 11s. Alternatively, the right and left equipment placement plates 13 may be divided into two in the vertical direction so that the left and right have different Z-direction dimensions. Furthermore, the right and left equipment placement plates 13 and 13 may have different numbers of divisions in the Z direction. Either the right or left equipment placement plate 13 or 13 may be divided into three or more divisions in the vertical direction.

[0018] Either the right supply placement board 13 or the left supply placement board 13 may be configured as a single piece without being divided vertically. Alternatively, either the right supply placement board 13 or the left supply placement board 13 may be configured as a single piece without being divided vertically. It should be noted that the right and left item placement plates 13 and 13 may have a dimension in the Y direction that is shorter than the dimension in the depth direction (front-rear direction) of the side panel 11s.

[0019] A tangential part 19 is arranged in a front position on the surface of the right equipment placement plate 13 opposite the surface facing the right side panel 11s. The tangential part 19 is a terminal block or a connector. A plurality of tangential parts 19 may be provided on the right equipment placement plate 13. The tangential part 19 is arranged close to the front surface 11f of the right equipment placement plate 13. Wiring drawn in from outside the housing 11 via the wiring inlet 11k is connected to the tangential part 19. At least one tangential part 19 can be arranged on each of the multiple right equipment placement plates 13.

[0020] A tangential part 19 is disposed in a front position on the surface of the left equipment placement plate 13 opposite to the surface facing the left side plate 11s. The tangential part 19 is a terminal block or a connector. A plurality of tangential parts 19 may be provided on the left equipment placement plate 13. The tangential part 19 is disposed close to the front surface 11f of the left equipment placement plate 13. The tangential part 19 is connected to the housing via a wiring inlet 11k. The tangential parts 19 are connected to the wiring drawn in from outside the body 11. At least one tangential part 19 can be arranged on each of the plurality of left accessory arrangement plates 13.

[0021] The tangential parts 19 are disposed in positions close to the wiring inlet 11k on the right and left equipment placement boards 13. By disconnecting the wiring connected to the tangential parts 19, the right or left equipment placement board 13 or 13 can be pulled forward as described below. The vertical position of the tangential parts 19 is not particularly limited as long as they are disposed on the front surface 11f of the right or left equipment placement board 13 or 13 close to the wiring inlet 11k. In addition, since the tangential part 19 is positioned close to the front surface 11f, the wiring connected to the tangential part 19 can be easily disconnected by simply opening the opening / closing door 12 without moving the right or left item placement board 13 in the Y direction.

[0022] At this time, the wiring has enough play to enable it to be disconnected from the tangential part 19. With the wiring connected to the tangential part 19, it is not anticipated that the right or left supply placement plate 13 will be pulled forward. Therefore, the wiring of the supply placement plate 13 to be pulled forward is first disconnected from the tangential part 19, and then the right or left supply placement plate 13 is pulled forward. For this reason, there is no need to provide excess play in the wiring to enable movement of the right or left supply placement plate 13 in the Y direction.

[0023] In this way, there is no need to provide excessive slack for wiring within the housing 11. Therefore, the wiring can be stored in an extremely neat state within the housing 11. Furthermore, there is no need to provide excessive slack in the housing 11 in order to store the wiring within the housing 11. Therefore, the space within the housing 11 can be used for other purposes. For example, the space that was previously used for slack for wiring within the housing 11 can be used to increase the number of accessories placed on the right accessory placement board 13 or the left accessory placement board 13. Alternatively, the space that was previously used for slack for wiring within the housing 11 can be used to increase the number of right accessory placement boards 13 or left accessory placement boards 13 installed.

[0024] The right supply placement plate 13, which is divided in the vertical direction, is supported on the right side panel 11s by a drawer mechanism 15. The left supply placement plate 13, which is divided in the vertical direction, is supported on the left side panel 11s by a drawer mechanism 15. The drawer mechanism 15 draws the supply arrangement plate 13 forward while maintaining the position stored inside the housing 11 (see Figure 3). The drawer mechanism 15 is a front-rear slide mechanism that supports the supply arrangement plate 13 so that it can move in the front-rear direction. The drawer mechanism 15 can employ a configuration such as a slide rail mechanism extending in the Y direction, a long hole extending in the Y direction and a protrusion that fits into this, or a link mechanism.

[0025] The drawer mechanism 15 extends in the Y direction. The drawer mechanism 15 can draw the right or left supply placement plate 13 forward without interfering with the opening and closing door 12. The drawer mechanism 15 can draw the right supply placement plate 13 forward without interfering with the left supply placement plate 13. The drawer mechanism 15 can draw the left supply placement plate 13 forward without interfering with the right supply placement plate 13.

[0026] Specifically, the drawer mechanism 15 extends along the upper and lower edges of the rectangular outline of the divided right supply placement plate 13. The drawer mechanism 15 is arranged in the front-to-rear direction. The drawer mechanism 15 is connected to the surface of the right supply placement plate 13 facing the right side panel 11s. The drawer mechanism 15 is connected to the inner surface of the right side panel 11s. The upper end of the right supply arrangement plate 13 located on the upper side may be supported on the back plate 11b by a drawer mechanism 15. In this case, the drawer mechanism 15 provided on the upper end of the right supply arrangement plate 13 protrudes forward in the Y direction from the back plate 11b. The lower end of the right supply placement plate 13 located on the lower side may be supported on the bottom plate 11d by a drawer mechanism 15. In this case, the drawer mechanism 15 provided at the lower end of the right supply placement plate 13 protrudes forward in the Y direction from the back plate 11b.

[0027] The drawer mechanism 15 extends along the upper and lower edges of the rectangular outline of the divided left supply placement plate 13. The drawer mechanism 15 is arranged in the front-to-rear direction. The drawer mechanism 15 is connected to the surface of the left supply placement plate 13 facing the left panel 11s. The drawer mechanism 15 is connected to the inner surface of the left panel 11s. The upper end of the left supply placement plate 13 located on the upper side may be supported on the back plate 11b by a drawer mechanism 15. In this case, the drawer mechanism 15 provided on the upper end of the left supply placement plate 13 protrudes forward in the Y direction from the back plate 11b. The lower end of the left supply placement plate 13 located on the lower side may be supported on the bottom plate 11d by a drawer mechanism 15. In this case, the drawer mechanism 15 provided at the lower end of the left supply placement plate 13 protrudes forward in the Y direction from the back plate 11b.

[0028] For example, inside the housing 11, on the right supply placement plate 13 located at the upper right, the drawer mechanism 15 along the upper edge is close to the top panel 11u. Inside the housing 11, on the right supply placement plate 13 located at the upper right, the drawer mechanism 15 along the lower edge is close to the upper edge of the right supply placement plate 13 located at the lower right. Inside the housing 11, on the right supply placement plate 13 located at the lower right, the drawer mechanism 15 along the lower edge is close to the bottom panel 11d.

[0029] Inside the housing 11, on the left supply placement plate 13 located at the upper left, the drawer mechanism 15 along the upper edge is close to the top panel 11u. Inside the housing 11, on the left supply placement plate 13 located at the upper left, the drawer mechanism 15 along the lower edge is close to the upper edge of the left supply placement plate 13 located at the lower left. Inside the housing 11, on the right supply placement plate 13 located at the lower left, the drawer mechanism 15 along the lower edge is close to the bottom panel 11d.

[0030] The wiring inlet 11k is used to draw in wiring from outside the housing 11. The wiring inlet 11k is arranged close to the front surface 11f of the housing 11. The wiring inlet 11k is arranged close to the front surface 11f of the bottom panel 11d. The wiring inlet 11k may also be arranged close to the front surfaces 11f of the side panels 11s, 11s. In this case, the wiring inlet 11k may also be arranged close to the front surface 11f of the right side panel 11s, which is covered by the right equipment placement panel 13.

[0031] The wiring inlet 11k may be arranged close to the front surface 11f of the left side panel 11s covered by the left equipment placement panel 13. The wiring inlet 11k may be arranged close to the front surface 11f of the top panel 11u. If necessary, the wiring inlet 11k can be arranged at any position on the housing 11. The arrangement position and number of the wiring inlets 11k can also be easily changed.

[0032] The housing 11 may house a rear item placement plate (item placement plate) 14 arranged parallel to the rear panel 11b. The rear item placement plate 14 is arranged in front of the rear panel 11b. The right end of the rear item placement plate 14 is close to the right item placement plate 13. The left end of the rear item placement plate 14 is close to the left item placement plate 13.

[0033] The rear item placement plate 14 is arranged to cover the front side of the rear panel 11b. The rear item placement plate 14 may have substantially the same contour shape as the rear panel 11b. The rear item placement plate 14 may also have a contour shape smaller than that of the rear panel 11b. The tangential parts 19 can be formed at any position on the rear accessory arrangement plate 14. The housing 11 can also have a wiring inlet 11k formed on the floor surface portion 11d or the like at a position corresponding to the tangential parts 19 of the rear accessory arrangement plate 14.

[0034] The rear item placement plate 14 can also be made movable in the front-to-rear direction relative to the rear plate 11b. The rear item placement plate 14 can also be made rotatable relative to the rear plate 11b around a rotation axis near either the left or right end. The rear item placement plate 14 can also be configured to be fixed to the rear plate 11b and not move relative to the rear plate 11b.

[0035] With this configuration, the door 12 of the control panel 10 is opened, and one of the supply arrangement boards 13 is moved forward in the Y direction by the drawer mechanism 15. In this example, the left supply arrangement board 13 located at the upper left in Figure 3 is moved forward in the Y direction by the drawer mechanism 15. Then, as shown in FIG. 3, the left item placement board 13 is pulled out from inside the housing 11 to an external position forward of the opening 11a of the housing 11 while maintaining the position in which it was stored inside the housing 11.

[0036] As a result, the surface of the upper left supply placement board 13 on which the supplies are mounted is pulled out to a position forward of the housing 11, and the board is ready for work. The surface on the left supply placement board 13 on which the supplies are mounted is not in close proximity to other supply placement boards 13 or supplies, and there is ample space near the mounting surface. This makes it easy to perform maintenance on the supplies on the left supply placement board 13.

[0037] In other words, because the pulled-out left equipment placement board 13 is positioned outside the opening 11a of the housing 11, the other equipment placement boards 13 stored inside the housing 11, the equipment mounted on the other equipment placement boards 13, the housing 11, the opening and closing door 12, etc. do not get in the way of the work. This improves accessibility for wiring work, maintenance work, etc. Here, maintenance work, etc. means attaching equipment to the equipment placement board 13, connecting wiring to the equipment placement board 13, or inspecting the equipment, wiring, etc.

[0038] Furthermore, even when two left-side component placement boards 13 requiring maintenance or other work are simultaneously moved outside the housing 11, the right-side component placement board 13, the components mounted on the right-side component placement board 13, the housing 11, the door 12, etc., do not interfere with the work. This improves work efficiency. Since there is no need to work in a narrow space, the risk of coming into contact with components during work can be reduced. Furthermore, since there is no need to perform work inside the housing 11, space can be saved. This allows for high-density mounting within the housing 11.

[0039] Furthermore, while the left supply placement board 13 is stored, the accessibility of the work can be improved by pulling out only one of the right supply placement boards 13, or by simultaneously moving the two flush right supply placement boards 13 outward from the opening 11a of the housing 11.

[0040] Furthermore, while there was previously a restriction on the attachment range of supplies to the supply arrangement board 13 at the rear side in the Y direction, this restriction on the attachment range of supplies to the supply arrangement board 13 can be eliminated. This makes it easy to flexibly change the supply arrangement inside the housing 11, that is, to change the layout. It also makes it easy to respond to an increase or decrease in the number of parts attached to the supply arrangement board 13.

[0041] Here, before moving any of the equipment placement boards 13, the wiring connected to the tangential parts 19 of that equipment placement board 13 is first disconnected. Then, the wiring does not need to be moved other than by removing it inside the housing 11. The wiring only needs to have enough slack to be removed inside the housing 11. In other words, the wiring only needs to be connected to the tangential parts 19 at a position stored inside the housing 11, and does not need to be long enough to follow the movement of the equipment placement board 13.

[0042] This minimizes the length of the wiring inside the housing 11, allowing for neat wiring arrangement within the housing 11. This eliminates the need for excess wire (wiring). By disconnecting the wiring of the tangential components 19, the housing 11 and the equipment placement board 13 can be separated. In other words, the shortest possible wiring can be achieved. At the same time, damage to the wires can be prevented.

[0043] Furthermore, since both the tangential part 19 and the wiring inlet 11k are disposed close to the front surface 11f, it becomes possible to easily remove the wires from the tangential part 19 when the opening and closing door 12 is opened. Since both the tangential part 19 and the wiring inlet 11k are disposed close to the front surface 11f, it becomes possible to reduce the length of the wiring inside the housing 11. Furthermore, since the tangential part 19 and the wiring inlet 11k are disposed on the front surface 11f, it becomes possible to prevent the wiring leading from the wiring inlet 11k to the tangential part 19 from accidentally coming into contact with other parts of the appliance inside the housing 11.

[0044] In addition, it is possible to set the item placement for each of the multiple item placement boards 13. Therefore, by standardizing the outline shape or item placement for the multiple item placement boards 13, it is possible to respond to even more flexible layout changes. By configuring multiple equipment placement boards 13 so that they can be divided at any position, the equipment placement boards 13 can be made lighter, sub-assembly is possible, and workability can be improved.

[0045] When maintenance or other work on the control panel 10 is completed, the equipment arrangement board 13 is moved backward in the Y direction by the drawer mechanism 15. After the equipment arrangement board 13 that was pulled out is moved to the storage position, the wiring is connected to the corresponding tangential parts 19. When all wiring is completed, the opening and closing door 12 is closed and the housing 11 is sealed.

[0046] (Second embodiment) The control panel of the second embodiment will be described below with reference to the drawings.

[0047] FIG. 4 is a perspective view showing an equipment arrangement plate and a drawer mechanism of the control panel in the embodiment. The difference between this embodiment and the first embodiment described above is the arrangement of the equipment placement board; other configurations corresponding to those of the first embodiment described above are given the same symbols and their descriptions are omitted.

[0048] 4, the control panel 10 of the embodiment has a central equipment placement plate (equipment placement plate) 13 provided between a right side panel 11s and a left side panel 11s located on the left and right sides in the X direction. The central equipment placement plate (equipment placement plate) 13 is arranged parallel to the right equipment placement plate 13 adjacent to the right side panel 11s and the left equipment placement plate 13 adjacent to the left side panel 11s.

[0049] The central item placement plate 13 is stored inside the housing 11. The central item placement plate 13 is arranged parallel to the right item placement plate 13 and the left item placement plate 13. The central item placement plate 13 is arranged spaced apart from the right item placement plate 13 in the X direction. The central item placement plate 13 is arranged spaced apart from the left item placement plate 13 in the X direction. The central item placement plate 13 is arranged so that the distance from the right item placement plate 13 in the X direction is equal to the distance from the left item placement plate 13. In this case, the space inside the housing 11 is divided into two in the X direction by the central item placement plate 13. On the central equipment placement board 13, equipment (not shown) can be mounted and placed on the surface facing the right equipment placement board 13 and the surface facing the left equipment placement board 13. The equipment includes a control board, electrical components, etc.

[0050] The central item placement plate 13 has a rectangular outline and is divided into a plurality of upper and lower pieces along parting lines extending in the front-rear direction. In this embodiment, the central item placement plate 13 is divided into two in the vertical direction in the space between the top panel 11u and the bottom panel 11d of the housing 11. The two central item placement plates 13 are arranged with a Z-direction dimension that is approximately equal to the distance between the top panel 11u and the bottom panel 11d. The two central item placement plates 13 may be divided to have approximately the same size as either the right item placement plate 13 or the left item placement plate 13 that are similarly divided in the Z direction. The Z-direction dimensions of the two central item placement plates 13 may be the same or different.

[0051] The two upper and lower central item placement plates 13 may be divided into two in the vertical direction so that they have different Z-direction dimensions from the right and left item placement plates 13. The central item placement plate 13 may be divided into three or more vertical divisions. The central item placement plate 13 may have a different number of divisions in the Z direction from the right and left item placement plates 13. The central item placement plate 13 may also be configured as a single plate without being divided in the vertical direction. The two divided central item placement boards 13 each have a dimension in the Y direction that is approximately the same as the dimension in the depth direction (front-rear direction) of the right item placement board 13 and the left item placement board 13.

[0052] A tangential part 19 is arranged on at least one of the surfaces of the central item placement plate 13 facing the right item placement plate 13 and the surface facing the left item placement plate 13. The tangential part 19 is arranged in a front position on the central item placement plate 13. The tangential part 19 is arranged in a position close to the opening 11a when the central item placement plate 13 is stored in the housing 11. The tangential part 19 is a terminal block or a connector. A plurality of tangential parts 19 may be provided on the central item placement plate 13. The tangential parts 19 may be arranged on both sides of the central item placement plate 13. Wiring drawn in from outside the housing 11 via the wiring inlet 11k is connected to the tangential part 19. At least one tangential part 19 can be arranged on each of the multiple central item placement plates 13.

[0053] The tangential part 19 is disposed in a position close to the wiring inlet 11k on the central equipment placement plate 13. By disconnecting the wiring connected to the tangential part 19, the central equipment placement plate 13 can be pulled out as described below. The vertical position of the tangential part 19 is not particularly limited as long as it is disposed on the front surface 11f side of the central equipment placement plate 13 close to the wiring inlet 11k. Furthermore, since the tangential part 19 is arranged close to the front surface 11f, the wiring connected to the tangential part 19 can be easily disconnected by simply opening the opening / closing door 12 without moving the central equipment arrangement plate 13 in the Y direction.

[0054] The central item placement plate 13 is divided into two parts in the vertical direction and is supported on the housing 11 by a drawer mechanism 15. The drawer mechanism 15 draws the central item placement plate 13 forward while maintaining its orientation stored inside the housing 11. The central drawer mechanism (drawer mechanism) 15 can employ a configuration such as a slide rail mechanism extending in the Y direction, a long hole extending in the Y direction and a protrusion that engages with it, or a link mechanism. The drawer mechanism 15 extends in the Y direction. The drawer mechanism 15 can draw the central item placement plate 13 forward without interfering with the opening and closing door 12. The drawer mechanism 15 can draw the central item placement plate 13 forward without interfering with the right and left item placement plates 13.

[0055] The drawer mechanisms 15 extend along the upper and lower edges of the rectangular outline of the divided central supply placement plate 13.

The drawer mechanism 15 provided at the lower end of the upper central item placement plate 13 protrudes from the back plate 11b parallel to the top plate 11u.

[0058] The drawer mechanism 15 provided at the lower end of the lower central item placement plate 13 is provided so as to be in contact with the bottom plate 11d. The lower end of the lower central item placement plate 13 is supported on the bottom plate 11d by the drawer mechanism 15. The lower end of the lower central item placement plate 13 may also be supported on the back plate 11b by the drawer mechanism 15.

[0059] The upper end of the lower central item placement plate 13 is supported on the back plate 11b by a drawer mechanism 15. The drawer mechanism 15 provided at the upper end of the lower central item placement plate 13 protrudes forward in the Y direction from the back plate 11b. The drawer mechanism 15 provided at the upper end of the lower central item placement plate 13 protrudes from the back plate 11b parallel to the bottom plate 11d.

[0060] In the central supply placement plate 13 located on the upper side, the drawer mechanism 15 along the lower edge is close to the upper edge of the central supply placement plate 13 located on the lower side. Inside the housing 11, in the central supply placement plate 13 located on the lower side, the drawer mechanism 15 along the upper edge is close to the lower edge of the central supply placement plate 13 located on the upper side. The drawer mechanism 15 that contacts along the top panel 11u is fixed to the top panel 11u, and the drawer mechanism 15 that contacts along the bottom panel 11d is fixed to the bottom panel 11d.

[0061] The drawer mechanism 15, which protrudes forward in the Y direction from the rear plate 11b, is fixed to the housing 11 by a support member such as a cantilever, one end of which is fixed to the rear plate 11b. Note that the drawer mechanism 15 disposed at a position spaced apart from any of the top plate 11u, bottom plate 11d, right side plate 11s, and left side plate 11s may be fixed to the rear plate 11b. Alternatively, the drawer mechanism 15 spaced apart from any of the top plate 11u, bottom plate 11d, right side plate 11s, and left side plate 11s may be fixed to a predetermined position by a support member fixed at an arbitrary position inside the housing 11.
