[0005] The cover may include a first plate-shaped member, a second plate-shaped member, and a limiting portion. The first plate-shaped member has, for example, a first surface facing the thickness direction. The second plate-shaped member has, for example, a second surface facing the thickness direction. Furthermore, the second plate-shaped member is moved in a movement direction along the first surface and combined with the first plate-shaped member in an opposing state with the second surface facing the first surface. The limiting portion is, for example, provided from one end to the other end of the first surface in the movement direction. Furthermore, the limiting portion limits the movement of the second plate-shaped member in the thickness direction, which is being moved in the movement direction, between a pair of side edges of the second plate-shaped member.

[0006] In this cover, the restricting portion is provided from one end to the other end of the first plate-like member in the movement direction, which prevents other components from being placed in the area between the pair of side edges, and this may prevent the area between the pair of side edges of the second plate-like member from being fully utilized.

[0007] The present disclosure aims to make it possible to more widely utilize the area between a pair of side ends of the second plate-shaped member compared to when the restricting portion is arranged from one end to the other end of the first plate-shaped member in the movement direction. [Means for solving the problem]

[0008] A first aspect of the present invention is a cover comprising: a first plate-shaped member having a first surface facing in the thickness direction; a second plate-shaped member having a second surface facing in the thickness direction and moved in a movement direction along the first surface so as to be combined with the first plate-shaped member in an opposing state with the second surface facing the first surface; a first limiting portion provided on the first surface at a portion of the movement direction and limiting the movement in the thickness direction of the second plate-shaped member being moved in the movement direction between a pair of side ends of the second plate-shaped member; and a second limiting portion provided on the first surface downstream of the movement direction relative to the first limiting portion and limiting the movement in the thickness direction of the second plate-shaped member being moved in the movement direction at each of the pair of side ends after the restriction by the first limiting portion is released.

[0018] In an eleventh aspect, in the tenth aspect, the opening width of the notch gradually increases toward the downstream side in the movement direction.

[0019] The twelfth aspect is the tenth aspect, further comprising a third limiting portion provided on the first surface and contacting the downstream end of the second plate-like member in the opposing state in the movement direction to limit the movement of the second plate-like member in the movement direction, and an insertion portion provided on the third limiting portion and inserted into an opening in the notch on the downstream side in the movement direction.

[0020] In the 13th aspect, in the first aspect, the second limiting portion has a contact portion that contacts the side end and limits the movement of the second plate-shaped member in the thickness direction and a direction intersecting the movement direction, and a clamping portion that is provided on the contact portion and clamps the second plate-shaped member between the side end and the first surface and limits the movement of the second plate-shaped member in the thickness direction.

[0026] A nineteenth aspect is an image forming apparatus including the housing according to the eighteenth aspect, and an image forming unit provided inside the housing and forming an image on a recording medium. [Effects of the Invention]

[0027] According to the configuration of the first aspect, the area between the pair of side ends of the second plate-shaped member can be more widely utilized than when the first limiting portion is provided from one end to the other end of the first plate-shaped member in the movement direction.

[0028] According to the configuration of the second aspect, when the restriction by the first limiting section is released, the second plate-like member is prevented from moving in the thickness direction, compared to when the second limiting section begins to restrict the movement of the second plate-like member in the thickness direction after the restriction by the first limiting section is released.

[0029] According to the configuration of the third aspect, movement of the second plate-shaped member in the thickness direction is suppressed midway between the pair of side ends, compared to when the first limiting portion is positioned at a distance from the second limiting portion that is less than 1 / 8 of the dimension between the pair of side ends.

[0030] According to the configuration of the fourth aspect, the transfer of the limiting function that limits the movement of the second plate-like member in the thickness direction from the first limiting portion to the second limiting portion is carried out more smoothly than when the first limiting portion is positioned at a distance from the second limiting portion that is more than 1 / 4 of the dimension between the pair of side ends.

[0031] According to the configuration of the fifth aspect, the transfer of the limiting function of limiting the movement of the second plate-like member in the thickness direction from the first limiting portion to the second limiting portion is carried out more smoothly than when the first limiting portion is positioned at a position less than 1 / 8 of the dimension between the pair of side ends from the midpoint between the pair of side ends.

[0032] According to the configuration of the sixth aspect, movement of the second plate-like member in the thickness direction at the midpoint between the pair of side ends is suppressed compared to when the first limiting portion is positioned at a position away from the midpoint between the pair of side ends that is more than 1 / 4 of the dimension between the pair of side ends.

[0033] According to the configuration of the seventh aspect, movement of the second plate-shaped member in the thickness direction is suppressed in the middle of the pair of side edges, compared to when only one first limiting portion is provided.

[0034] According to the configuration of the eighth aspect, movement of the second plate-shaped member in the thickness direction is suppressed throughout the entire second plate-shaped member, compared to when multiple first limiting portions are arranged at positions less than 1 / 8 of the dimension between a pair of side ends.

[0035] According to the configuration of the ninth aspect, movement of the second plate-like member in the thickness direction is suppressed over a longer range in the movement direction of the second plate-like member compared to when the length of one first limiting portion in the movement direction is the same as the length of the other first limiting portion in the movement direction.

[0036] According to the configuration of the tenth aspect, the movement of the second plate-shaped member in the thickness direction can be suppressed by the insertion operation of inserting the protruding portion into the notch.

[0037] According to the configuration of the eleventh aspect, it is easier to insert the protrusion into the notch compared to when the opening width of the notch is constant toward the downstream side in the movement direction.

[0038] According to the configuration of the twelfth aspect, the opening of the notch on the downstream side in the movement direction can be hidden by the insertion portion.

[0039] According to the configuration of the 13th aspect, both the movement of the second plate-shaped member in the thickness direction and the movement in the transverse direction are suppressed compared to when the second limiting portion only limits the movement of the second plate-shaped member in the thickness direction.

[0040] According to the configuration of the fourteenth aspect, the clipping portion is less likely to protrude in the thickness direction from the opposite surface of the other portion, compared to when the height in the thickness direction on the opposite surface of the second plate-shaped member is constant.

[0041] According to the configuration of the 15th aspect, movement of the opposing second plate-like member in the thickness direction, movement in the movement direction, and movement in the intersecting direction are suppressed compared to when the cover has only the first limiting portion and the second limiting portion.

[0042] According to the configuration of the sixteenth aspect, movement of the second plate-shaped member in the intersecting direction is suppressed more than when the cover is provided with only the first limiting portion and the second limiting portion.

[0043] According to the configuration of the seventeenth aspect, the area between the pair of side ends can be more widely utilized than when the fifth limiting portion is always in contact with the first surface.

[0044] According to the configuration of the 18th aspect, the area between the pair of side ends of the second plate-like member can be more widely utilized than when the first limiting portion is provided from one end to the other end of the first plate-like member in the movement direction.

[0045] According to the configuration of the 19th aspect, the area between the pair of side ends of the second plate-like member can be more widely utilized than when the first limiting portion is provided from one end to the other end of the first plate-like member in the movement direction.

DETAILED DESCRIPTION OF THE INVENTION

[0047] An example of an embodiment of the present invention will be described below with reference to the drawings.

[0048] <Image forming apparatus 10> The configuration of an image forming apparatus 10 according to this embodiment will be described. Fig. 1 is a perspective view showing the image forming apparatus 10. Fig. 2 is a front cross-sectional view showing the image forming apparatus 10.

[0049] Note that the arrow UP in the figure indicates the top of the device. The arrow DO in the figure indicates the bottom of the device. The arrow LH in the figure indicates the left of the device. The arrow RH in the figure indicates the right of the device. The arrow FR in the figure indicates the front of the device. The arrow RR in the figure indicates the rear of the device. These directions are defined for the convenience of explanation, and the device configuration is not limited to these directions. Note that in each direction of the device, the word "device" may be omitted. For example, "above the device" may be simply referred to as "above."

[0050] In the following description, the "up-down direction" may be used to mean "both above and below" or "either above or below." The "left-right direction" may be used to mean "both right and left" or "either right or left." The "left-right direction" may also be referred to as the side, lateral, width, and horizontal direction. The "front-rear direction" may be used to mean "both forward and backward" or "either forward or backward." The "front-rear direction" may also be referred to as the side, lateral, and horizontal direction. The up-down direction, left-right direction, and front-rear direction are directions that intersect with each other (specifically, directions that are perpendicular to each other).

[0051] In the figures, the symbol "x" inside a "circle" indicates an arrow pointing from the front to the back of the page. In the figures, the symbol "·" inside a "circle" indicates an arrow pointing from the back to the front of the page. The dimensional ratios of the parts shown in each figure in the up-down, left-right, and front-to-back directions may differ from the actual dimensional ratios.

[0052] The image forming apparatus 10 shown in Figures 1 and 2 is an apparatus that forms an image. Specifically, as shown in Figure 1, the image forming apparatus 10 includes an image forming apparatus main body 11, a medium storage unit 12, and a cover 18. As shown in Figure 2, the image forming apparatus 10 also includes a medium discharge unit 13, an image forming unit 14, and a conveying mechanism 16. Each unit of the image forming apparatus 10 will be described below.

[0053] <Image forming apparatus main body 11> 1 and 2 is an attachment target to which the cover 18 is attached, and is a portion where each component of the image forming device 10 is provided. Specifically, the image forming device body 11 is formed in a box shape (specifically, a substantially rectangular parallelepiped shape) with an open front.

[0054] This image forming apparatus main body 11 and a cover 18 attached to the front of the image forming apparatus main body 11 constitute a housing 15. In other words, the image forming apparatus main body 11 functions as an example of a housing main body to which the cover 18 is attached. The housing is a box that houses elements (specifically, parts, devices, etc.) having predetermined functions inside.

[0055] 2, for example, the medium storage unit 12, the image forming unit 14, and the transport mechanism 16 are provided inside the image forming device main body 11. The medium discharge unit 13 is provided on the right side surface of the image forming device main body 11, as shown in FIG.

[0056] <Medium storage section 12> 2, the medium storage unit 12 is a portion of the image forming apparatus 10 that stores the recording medium P. The recording medium P stored in the medium storage unit 12 is supplied to the image forming unit 14. Note that, for example, paper is used as the recording medium P.

[0057] <Media discharge section 13> 2 is a portion of the image forming apparatus 10 to which the recording medium P is discharged. The recording medium P on which an image has been formed by the image forming unit 14 is discharged to the medium discharge portion 13.

[0058] <Image forming unit 14> 2 has a function of forming an image on the recording medium P sent out from the medium storage unit 12. As the image forming unit 14, for example, an electrophotographic image forming unit that forms an image on the recording medium P using toner is used.

[0059] In an electrophotographic image forming unit, for example, the steps of charging, exposure, development, transfer, and fixing are performed to form an image on the recording medium P. Note that the image forming unit is not limited to an electrophotographic image forming unit. For example, an inkjet image forming unit may also be used as an example of the image forming unit, and various image forming units can be used. In an inkjet image forming unit, for example, an image is formed on the recording medium P by ejecting ink droplets from an ejection unit onto the recording medium P.

[0060] <Transport mechanism 16> 2 is a mechanism for transporting the recording medium P. The transport mechanism 16 transports the recording medium P by a transport member 17 such as a transport roll, for example. The transport member 17 may be a transport belt or the like, as long as it is a member that can apply a transport force to the recording medium P and transport the recording medium P.

[0061] The transport mechanism 16 transports the recording medium P from the medium storage unit 12 to the image forming unit 14. Furthermore, the transport mechanism 16 transports the recording medium P from the image forming unit 14 to the medium discharge unit 13.

[0062] <Cover 18> Fig. 3 is a side view showing a part of the image forming apparatus 10 including the cover 18. Fig. 4 is a perspective view showing the cover 18. Fig. 5 is a rear view showing the cover 18.

[0063] Cover 18 has a function of covering, for example, the front portion of image forming apparatus 10 (see FIG. 1). Cover 18 is provided on image forming apparatus main body 11 in an openable and closable manner, as shown in FIG. 3. In this embodiment, cover 18 is attached to image forming apparatus main body 11 in an openable and closable manner between a closed position (position indicated by a solid line in FIG. 3) and an open position (position indicated by a two-dot chain line in FIG. 3).

[0064] In the following description of the cover 18, the up / down, left / right, front / back directions are indicated based on the state in which the cover 18 is closed relative to the image forming apparatus main body 11 (i.e., the state in which the cover 18 is in the closed position).

[0065] 4 and 5, the cover 18 specifically includes a first plate-shaped member 30 and a second plate-shaped member 20. Furthermore, the cover 18 includes first limiting portions 51, 52, second limiting portions 61, 62, third limiting portions 71, 72, fourth limiting portions 91, 92, and ribs 80, 81, 82, 83. Each portion of the cover 18 will be described below.

[0066] <First plate-shaped member 30> Fig. 6 is a perspective view showing the first plate-shaped member 30. Fig. 7 is a rear view showing the first plate-shaped member 30.

[0067] As shown in Fig. 6, the first plate-shaped member 30 is formed in a plate shape with its thickness direction aligned in the front-rear direction. In this embodiment, the first plate-shaped member 30 is formed from a single plate material with its thickness direction aligned in the front-rear direction. The first plate-shaped member 30 has a first surface 30A facing in the thickness direction. In this embodiment, the first surface 30A is, for example, a flat surface facing rearward.

[0068] 6 and 7, first limiting portions 51, 52, second limiting portions 61, 62, third limiting portions 71, 72, and fourth limiting portions 91, 92 are provided on the first surface 30A of the first plate-shaped member 30. The first limiting portions 51, 52, second limiting portions 61, 62, third limiting portions 71, 72, and fourth limiting portions 91, 92 will be described later.

[0069] <Second plate-shaped member 20> Fig. 8 is a perspective view showing the second plate-shaped member 20. Fig. 9 is a rear view showing the second plate-shaped member 20. Fig. 10 is a front view showing the second plate-shaped member 20. Fig. 11 is a plan view showing a part of the second plate-shaped member 20. Fig. 12 is a plan view showing a state in which restriction by the first restricting portions 51, 52 has started in the configuration shown in Fig. 11.

[0070] As shown in Fig. 8, the second plate-shaped member 20 is formed in a plate shape with its thickness direction extending in the front-rear direction. In this embodiment, the second plate-shaped member 20 is formed by a plurality of walls, as will be described later. The second plate-shaped member 20 has a second surface 20A (see Fig. 10) facing in the thickness direction. The second surface 20A is a flat surface facing forward.

[0071] The second plate-shaped member 20 is moved upward and combined with the first plate-shaped member 30 in a state where the second surface 20A faces the first surface 30A (hereinafter referred to as the facing state). In this way, the first plate-shaped member 30 and the second plate-shaped member 20 are combined after moving upward to form the cover 18. This makes it possible to reduce the thickness of the cover 18 while increasing its rigidity.

[0072] The upward direction is an example of the movement direction along the first surface. The state shown in Figures 4 and 5 is the opposing state of the second plate-shaped member 20.

[0073] Specifically, as shown in Figures 8, 9, and 10, the second plate-shaped member 20 has rear walls 21, 22, and 23, right walls 24 and 25, left walls 26 and 27, an upper wall 28, and a lower wall 29. Furthermore, the second plate-shaped member 20 has insertion portions 40 and 41, V-shaped walls 44 and 45, and fixing portions 48 and 49. Furthermore, the second plate-shaped member 20 is provided with ribs 80, 81, 82, and 83. The ribs 80, 81, 82, and 83 are an example of fifth limiting portions.

[0074] The right wall 24 constitutes the right end (the rightmost part) of the second plate-shaped member 20 above the fixing portion 48. The left wall 26 constitutes the left end (the leftmost part) of the second plate-shaped member 20 above the fixing portion 49. The right wall 24 and the left wall 26 are an example of a pair of side ends.

[0075] The right wall 25 is disposed rearward and to the left of the right wall 24. The right walls 24, 25 are formed in a plate shape with a thickness extending in the left-right direction. The right walls 24, 25 constitute the right side plate of the second plate-shaped member 20.

[0076] The left wall 27 is disposed rearward and to the right of the left wall 26. The left walls 26, 27 are formed in a plate shape with a thickness extending in the left-right direction. The left walls 26, 27 constitute the left side plate of the second plate-shaped member 20.

[0077] The rear wall 22 is disposed between the right wall 25 and the left wall 27. The rear wall 22 is connected to the rear end of the right wall 25 and the rear end of the left wall 27. The rear wall 21 is disposed between the right wall 24 and the right wall 25. The rear wall 21 is connected to the rear end of the right wall 24 and the front end of the right wall 25. The rear wall 23 is disposed between the left wall 26 and the left wall 27. The rear wall 23 is connected to the rear end of the left wall 26 and the front end of the left wall 27.

[0078] The rear walls 21, 22, and 23 are formed in a plate shape with the thickness direction being the front-rear direction. The rear walls 21, 22, and 23 form the rear plate of the second plate-shaped member 20.

[0079] The rear wall 21 is disposed forward and to the right of the rear wall 22. The rear wall 23 is disposed forward and to the left of the rear wall 22. Therefore, when the second plate-shaped member 20 is in an opposing state (see FIG. 4), the rear walls 21, 23 are disposed closer to the first plate-shaped member 30 than the rear wall 22. As a result, the dimension of the second plate-shaped member 20 in the front-to-rear direction (i.e., the dimension in the thickness direction) is smaller in the areas of the rear walls 21, 23 than in the area of ​​the rear wall 22.

[0080] The lower wall 29 is connected to the lower ends of the right walls 24, 25 and the lower ends of the left walls 26, 27. The dimension of the lower wall 29 in the front-to-rear direction is smaller at the rear walls 21, 23 portions than at the rear wall 22 portion. The lower wall 29 is formed in a plate shape with its thickness direction extending in the up-down direction. The lower wall 29 constitutes the lower plate of the second plate-shaped member 20.

[0081] A pair of insertion holes 29A into which insertion portions 54 (described later) of the first restricting portions 51, 52 are inserted are formed in the lower wall 29. The pair of insertion holes 29A are arranged with a gap between them in the left-right direction.

[0082] The fixing portion 48 protrudes to the right at the lower end of the right wall 24. The fixing portion 48 is formed in a plate shape with its thickness direction in the front-to-rear direction. The rear surface of the fixing portion 48 is flush with the rear surface of the rear wall 21. The fixing portion 48 is formed with a through hole 48A through which a fastening member (not shown) is passed to be fastened to a fastening hole 57 (described later) of the first plate-shaped member 30. The fastening member is passed through the through hole 48A and fastened to the fastening hole 57, thereby fixing the second plate-shaped member 20 to the first plate-shaped member 30.

[0083] The fixing portion 49 protrudes to the left at the lower end of the left wall 26. The fixing portion 49 is formed in a plate shape with its thickness direction in the front-to-rear direction. The rear surface of the fixing portion 49 is flush with the rear surface of the rear wall 23. The fixing portion 49 is formed with a through hole 49A through which a fastening member (not shown) is passed to be fastened to a fastening hole 57 (described later) of the first plate-shaped member 30. The fastening member is passed through the through hole 49A and fastened to the fastening hole 57, whereby the second plate-shaped member 20 is fixed to the first plate-shaped member 30.

[0084] The upper wall 28 is connected to the upper ends of the right walls 24, 25 and the upper ends of the left walls 26, 27. The dimension of the upper wall 28 in the front-to-rear direction is smaller at the rear walls 21, 23 portions than at the rear wall 22 portion. The upper wall 28 is formed in a plate shape with its thickness direction extending in the up-down direction. The upper wall 28 constitutes the upper plate of the second plate-shaped member 20.

[0085] A pair of grooves 22A, 22B are formed in the upper end of the rear wall 22 and the upper wall 28. The pair of grooves 22A, 22B are spaced apart in the left-right direction. Specifically, as shown in Fig. 9, groove 22A is located at an intermediate position 202 between a middle portion 204 of the second plate-shaped member 20 in the left-right direction and the right wall 24. Groove 22B is located at an intermediate position 206 between the middle portion 204 and the left wall 26.

[0086] Each of the grooves 22A, 22B opens rearward in the rear wall 22 and upward in the upper wall 28. The opening width of each of the grooves 22A, 22B gradually increases toward the upper side. As a result, each of the grooves 22A, 22B is formed in a substantially triangular shape when viewed from the rear. Note that rearward view refers to the view from the rear side toward the front side.

[0087] 10, each of the V-shaped walls 44, 45 is formed in a substantially V-shape in rear view along the hypotenuse of each of the substantially triangular grooves 22A, 22B. Upper ends of ribs 80, 81 arranged at intervals in the left-right direction are connected to the V-shaped wall 44. Upper ends of ribs 82, 83 arranged at intervals in the left-right direction are connected to the V-shaped wall 45.

[0088] 11, an opening 46 through which each of the first restricting portions 51 and 52 passes is formed in each of the V-shaped walls 44 and 45. The opening 46 of the V-shaped wall 44 is disposed between the ribs 80 and 81. The opening 46 of the V-shaped wall 45 is disposed between the ribs 82 and 83. The specific configurations of the ribs 80, 81, 82, and 83 will be described later.

[0089] The insertion portions 40, 41 are components that are inserted between the first limiting portions 51, 52 and the first surface 30A. Each of the insertion portions 40, 41 is provided in each of the groove portions 22A, 22B. Each of the insertion portions 40, 41 is formed in a plate shape with its thickness direction in the front-to-rear direction. Each of the insertion portions 40, 41 has a notch 42, 43 that opens at the upper end and is formed toward the lower side. The opening width of the notch 42, 43 gradually increases toward the upper side. The upper end is an example of the downstream end in the movement direction. The lower side is an example of the upstream side in the movement direction. The upper side is an example of the downstream side in the movement direction.

[0090] <First limiting portions 51, 52> The first limiting portions 51, 52 have a function of restricting the movement in the thickness direction (specifically, rearward) of the second plate-shaped member 20, which is being moved upward relative to the first plate-shaped member 30. In this embodiment, the first limiting portions 51, 52 restrict this movement between the right wall 24 and the left wall 26 of the second plate-shaped member 20. Note that this movement also includes the case where the second plate-shaped member 20 moves relative to the first plate-shaped member 30.

[0091] The first limiting portions 51 and 52 are provided in a part of the first surface 30A in the movement direction (specifically, the up-down direction). Specifically, the first limiting portions 51 and 52 are provided in a lower part of the first surface 30A (a part below the center of the first surface 30A in the up-down direction).

[0092] The first limiting portions 51, 52 are disposed between the right wall 24 and the left wall 26, at a portion of the second plate-like member 20 in the left-right direction. Furthermore, the first limiting portions 51, 52 are disposed apart in the left-right direction. The left-right direction is an example of a direction intersecting the thickness direction and the movement direction. Note that the left-right direction can also be said to be a direction intersecting the movement direction and along the first surface. The left-right direction can also be said to be a direction from one of the right wall 24 and the left wall 26 to the other.

[0093] Specifically, each of the first limiting portions 51, 52 has a protruding portion 53 that protrudes from the first surface 30A and is inserted into each of the notches 42, 43. The protruding portion 53 has a shaft portion 53A that protrudes rearward from the first surface 30A, and a protruding portion 53B that protrudes in the left-right direction from the shaft portion 53A on the shaft portion 53A.

[0094] The second plate-shaped member 20 is moved in a state in which each of the insertion portions 40, 41 is inserted into the gap between the protruding portion 53B and the first surface 30A at each of the first limiting portions 51, 52. As a result, the first limiting portions 51, 52 limit the movement of the second plate-shaped member 20, which is being moved upward, in the thickness direction (specifically, backward).

[0095] Furthermore, the first limiting portions 51, 52 limit the left-right movement of the second plate-shaped member 20 that has been moved upward as a result of the shaft portion 53A coming into contact with the insertion portions 40, 41.

[0096] The length of the shaft portion 53A and the protruding portion 53B of the first limiting portion 51 in the up-down direction is longer than the corresponding length of the first limiting portion 52. Therefore, the length of the first limiting portion 51 in the up-down direction is longer than that of the first limiting portion 52. Note that the first limiting portion 51 is an example of one first limiting portion. The first limiting portion 52 is an example of another first limiting portion.

[0097] A part of the first limiting portion 51 and the entire first limiting portion 52 overlap in a side view. A side view refers to a view from one of the left and right sides toward the other.

[0098] The lower ends of the first limiting portions 51 and 52 are positioned at the same vertical position on the first surface 30A. Therefore, the first limiting portions 51 and 52 start restricting the movement of the second plate-like member 20 in the thickness direction at the same time.

[0099] The upper end of the first limiting portion 51 is disposed on the first surface 30A above the upper end of the first limiting portion 52. Therefore, after the first limiting portion 52 finishes limiting the movement of the second plate-shaped member 20 in the thickness direction, the first limiting portion 51 finishes limiting the movement of the second plate-shaped member 20 in the thickness direction. In other words, the timing at which the first limiting portion 51 finishes limiting the movement of the second plate-shaped member 20 in the thickness direction is later than that of the second plate-shaped member 20.

[0100] Furthermore, each of the first limiting portions 51, 52 has an insertion portion 54 that is inserted into the insertion hole 29A. This insertion portion 54 protrudes rearward from the overhanging portion 53B of the protruding portion 53. In each of the first limiting portions 51, 52, when the second plate-shaped member 20 is facing each other, the insertion portion 54 is inserted into each of the pair of insertion holes 29A. By inserting the insertion portion 54 into the insertion hole 29A, movement of the second plate-shaped member 20 in the up-down and left-right directions is restricted. Note that the cover of the present disclosure may be configured without the insertion portion 54 and the insertion hole 29A.

[0101] <Second limiting portions 61, 62> The second limiting portions 61, 62 have a function of restricting the movement of the second plate-shaped member 20 in the thickness direction (specifically, rearward) as it is being moved upward. In this embodiment, the second limiting portions 61, 62 restrict the movement at each of the right wall 24 and the left wall 26 after the restriction by the first limiting portions 51, 52 is released. Furthermore, in this embodiment, the second limiting portions 61, 62 start restricting the movement before the restriction by the first limiting portions 51, 52 is released. In this way, in this embodiment, the restricting function of restricting the movement of the second plate-shaped member 20 in the thickness direction is transferred from the first limiting portions 51, 52 to the second limiting portions 61, 62.

[0102] The second limiting portions 61, 62 are provided on the first surface 30A above the first limiting portions 51, 52. Each of the second limiting portions 61, 62 is arranged along the right wall 24 and the left wall 26. As a result, after the restriction by the first limiting portions 51, 52 is released, the movement of the second plate-shaped member 20 in the thickness direction is restricted by each of the right wall 24 and the left wall 26. The second limiting portions 61, 62 are provided in the lower part of the first surface 30A (parts below the center of the first surface 30A in the up-down direction).

[0103] 6, the second limiting portions 61, 62 specifically have contact portions 63, 64 and clamping portions 65, 66. The contact portions 63, 64 extend rearward from the first surface 30A. The contact portions 63, 64 are formed in a plate shape with a thickness extending in the left-right direction.

[0104] The contact portion 63 is disposed on the outer side (specifically, the right side) of the right wall 24. The contact portion 64 is disposed on the outer side (specifically, the left side) of the left wall 26. The contact portion 63 contacts the right wall 24, and the contact portion 64 contacts the left wall 26, thereby restricting the movement of the second plate-shaped member 20 in the left-right direction.

[0105] The clamping portions 65 and 66 are provided on the contact portions 63 and 64. Specifically, the clamping portion 65 extends leftward from the rear end portion of the contact portion 63. Specifically, the clamping portion 66 extends rightward from the rear end portion of the contact portion 64. The clamping portions 65 and 66 are formed in the shape of a plate with a thickness extending in the front-to-rear direction.

[0106] The clamping portions 65, 66 clamp the second plate-shaped member 20 between the right wall 24 and the left wall 26 and the first surface 30A, thereby restricting movement of the second plate-shaped member 20 in the thickness direction. The clamping portions 65, 66 contact the rear walls 21, 23 of the second plate-shaped member 20.

[0107] The rear surface 20B of the second plate-shaped member 20 is a portion sandwiched between the sandwiching portions 65 and 66 (specifically, rear walls 21 and 23), and is lower in height in the thickness direction than the other portion (specifically, rear wall 22). The rear surface 20B is an example of an opposite surface opposite to the second surface.

[0108] In this embodiment, the lower ends of the second limiting portions 61, 62 (specifically, the contact portions 63, 64 and the clamping portions 65, 66) are disposed below the upper ends of the first limiting portions 51, 52 (specifically, the shaft portion 53A and the protruding portion 53B). That is, the lower portions of the second limiting portions 61, 62 overlap with the upper portions of the first limiting portions 51, 52 in a side view.

[0109] As a result, in this embodiment, the movement restriction by the second restricting portions 61 and 62 begins before the movement restriction by the first restricting portions 51 and 52 is released.

[0110] Furthermore, even if the lower end of the second restricting sections 61, 62 is positioned higher than the upper end of the first restricting sections 51, 52, if the following conditions are met, the movement restriction by the second restricting sections 61, 62 will begin before the movement restriction by the first restricting sections 51, 52 is released.

[0111] The condition is that the vertical distance from the first limiting portions 51, 52 to the second limiting portions 61, 62 is shorter than the vertical dimension of the insertion portions 40, 41. The vertical dimension of the insertion portions 40, 41 is the vertical length of the portion inserted between the first limiting portions 51, 52 and the first surface 30A.

[0112] In this embodiment, as the second plate-shaped member 20 moves, the state in which the movement of the second plate-shaped member 20 in the thickness direction is restricted by the first restricting portions 51, 52 and the second restricting portions 61, 62 transitions in the order of a first restricting state, a second restricting state, and a third restricting state. The first restricting state (see FIG. 13) is a state in which the first restricting portions 51, 52 restrict the movement of the second plate-shaped member 20 in the thickness direction, and the second restricting portions 61, 62 do not restrict the movement of the second plate-shaped member 20 in the thickness direction. The second restricting state (see FIG. 14) is a state in which both the first restricting portions 51, 52 and the second restricting portions 61, 62 restrict the movement of the second plate-shaped member 20 in the thickness direction. The third restricting state (see FIG. 15) is a state in which the second restricting portions 61, 62 restrict the movement of the second plate-shaped member 20 in the thickness direction, and the first restricting portions 51, 52 do not restrict the movement of the second plate-shaped member 20 in the thickness direction.

[0113] As described above, in this embodiment, the first limiting portions 51, 52 and the second limiting portions 61, 62 share the role of limiting the movement of the second plate-shaped member 20. This makes it possible to reduce the range of movement restriction performed by the first limiting portions 51, 52. As a result, it is possible to reduce the vertical dimension of the first limiting portions 51, 52.

[0114] <Positions of the first limiting portions 51, 52 and the second limiting portions 61, 62> 16 , each of the first limiting portions 51, 52 is disposed at a position that is spaced apart from each of the second limiting portions 61, 62 by at least ⅛ of the dimension WA between the right wall 24 and the left wall 26. Specifically, each of the first limiting portions 51, 52 is disposed at a position that is at least ⅛ and at most ¼ of the dimension WA from each of the second limiting portions 61, 62. In the present embodiment, each of the first limiting portions 51, 52 is disposed at a position that is approximately ¼ of the dimension WA from each of the second limiting portions 61, 62.

[0115] 16, the outer edge of the second plate-shaped member 20, excluding the fixing portions 48 and 49, is indicated by a two-dot chain line. Also, in FIG. 16, the positions through which the dashed dot line passes (including the intermediate positions 202, 204, and 206) indicate positions that divide the dimension WA into approximately eight equal parts. Therefore, the dimension between the dashed dotted lines corresponds to 1 / 8 of the dimension WA.

[0116] Furthermore, each of the first limiting portions 51, 52 is disposed at a position that is at least 1 / 8 of the dimension WA away from a middle 204 between the right wall 24 and the left wall 26. Specifically, each of the first limiting portions 51, 52 is disposed at a position that is at least 1 / 8 and at most 1 / 4 of the dimension WA away from the middle 204. In this embodiment, the first limiting portions 51, 52 are disposed at a position that is at most 1 / 4 of the dimension WA away from the middle 204.

[0117] In this embodiment, the distance from the middle 204 to the right wall 24 is approximately equal to the distance from the middle 204 to the left wall 26. The middle 204 is an example of the middle between a pair of side edges. The middle 204 can also be said to be the middle position of the second plate-shaped member 20 in the left-right direction.

[0118] Furthermore, the first limiting portions 51, 52 are disposed at positions spaced apart by at least 1 / 8 of the dimension WA. Specifically, the first limiting portions 51, 52 are disposed at positions spaced apart by at least 1 / 4 and not more than 1 / 2 of the dimension WA. In this embodiment, the first limiting portions 51, 52 are disposed at positions spaced apart by approximately 1 / 2 of the dimension WA.

[0119] In this embodiment, the first limiting portion 51 is disposed at an intermediate position 202 between a middle 204 in the left-right direction of the second plate-shaped member 20 and the right wall 24. The intermediate position 202 can also be referred to as a position between the middle 204 and the second limiting portion 61. The first limiting portion 52 is disposed at an intermediate position 206 between the middle 204 and the left wall 26. The intermediate position 206 can also be referred to as a position between the middle 204 and the second limiting portion 62.

[0120] The intermediate position 202 is set, for example, at a position that divides the dimension from the middle 204 to the second limiting portion 61 approximately equally. The intermediate position 206 is set, for example, at a position that divides the dimension from the middle 204 to the second limiting portion 62 approximately equally.

[0121] The positions of the first limiting portions 51 and 52 are based on, for example, the center in the left-right direction, and the positions of the second limiting portions 61 and 62 are based on, for example, the contact surfaces of the contact portions 63 and 64 with the second plate-shaped member 20.

[0122] <Third limiting parts 71, 72> The third limiting portions 71, 72 abut against the upper end of the second plate-shaped member 20 facing the first plate-shaped member 30, thereby limiting the upward movement of the second plate-shaped member 20. The third limiting portions 71, 72 are provided on the first surface 30A. Specifically, the third limiting portions 71, 72 extend from the first surface 30A. The third limiting portions 71, 72 are formed in a plate shape with the thickness direction extending in the up-down direction.

[0123] The third limiting portions 71, 72 are provided with insertion portions 73, 74 that are inserted into the cutouts 42, 43. The insertion portions 73, 74 extend downward from the third limiting portions 71, 72. Specifically, the insertion portions 73, 74 extend downward from the center of the third limiting portions 71, 72 in the left-right direction. As a result, the third limiting portions 71, 72 and the insertion portions 73, 74 form a T-shape. The insertion portions 73, 74 extend rearward when viewed from the first surface 30A. The insertion portions 73, 74 are inserted into the upper openings of the cutouts 42, 43.

[0124] <Fourth Restriction Section 91, 92> The fourth limiting portions 91, 92 limit movement of the second plate-shaped member 20 in the front-rear direction, upward, and left-right direction. Note that the front-rear direction is an example of the thickness direction.

[0125] The fourth limiting portions 91 and 92 are provided on the first surface 30A of the first plate-shaped member 30. Specifically, the fourth limiting portion 91 is provided on the upper portion of the first surface 30A (a portion above the center in the vertical direction of the first surface 30A) and on the right portion of the first surface 30A (a portion to the right of the center in the horizontal direction of the first surface 30A). The fourth limiting portion 92 is provided on the upper portion of the first surface 30A (a portion above the center in the vertical direction of the first surface 30A) and on the left portion of the first surface 30A (a portion to the left of the center in the horizontal direction of the first surface 30A).

[0126] The fourth limiting portion 91 receives the upper and right corners of the opposing second plate-shaped member 20. Specifically, the fourth limiting portion 91 has contact portions 91A, 91B, and 91C. The contact portion 91A is formed in a plate shape with its thickness direction extending in the up-down direction, and extends rearward from the first surface 30A. The contact portion 91A comes into contact with the right end of the upper wall 28 of the second plate-shaped member 20. This limits the upward movement of the second plate-shaped member 20.

[0127] The contact portion 91B is formed in a plate shape with its thickness in the left-right direction and extends rearward from the first surface 30A. The upper end of the contact portion 91B is connected to the right end of the contact portion 91A. The contact portion 91B comes into contact with the upper end of the right wall 24 of the second plate-shaped member 20. This restricts the second plate-shaped member 20 from moving rightward.

[0128] The contact portion 91C is formed in a plate shape with its thickness in the front-rear direction and has a triangular shape when viewed from the rear. The upper end of the contact portion 91C is connected to the rear end of the contact portion 91A, and the right end of the contact portion 91C is connected to the rear end of the contact portion 91B.

[0129] The contact portion 91C comes into contact with the upper end of the rear wall 21 of the second plate-shaped member 20. As a result, the second plate-shaped member 20 is sandwiched in the front-rear direction between the contact portion 91C and the first surface 30A, and movement of the second plate-shaped member 20 in the front-rear direction is restricted.

[0130] The fourth limiting portion 92 receives the upper and left corners of the opposing second plate-shaped member 20. Specifically, the fourth limiting portion 92 has contact portions 92A, 92B, and 92C. The contact portion 92A is formed in a plate shape with its thickness direction extending in the up-down direction, and extends rearward from the first surface 30A. The contact portion 92A comes into contact with the left end of the upper wall 28 of the second plate-shaped member 20. This limits the upward movement of the second plate-shaped member 20.

[0131] The contact portion 92B is formed in a plate shape with its thickness in the left-right direction, and extends rearward from the first surface 30A. The upper end of the contact portion 92B is connected to the left end of the contact portion 92A. The contact portion 92B contacts the upper end of the left wall 26 of the second plate-shaped member 20. This restricts the movement of the second plate-shaped member 20 to the left. In this embodiment, the second plate-shaped member 20 is sandwiched in the left-right direction between the contact portion 91B and the contact portion 92B, restricting the movement of the second plate-shaped member 20 in the left-right direction.

[0132] The contact portion 92C is formed in a plate shape with its thickness in the front-to-rear direction and has a triangular shape when viewed from the rear. The upper end of the contact portion 92C is connected to the rear end of the contact portion 92A, and the left end of the contact portion 92C is connected to the rear end of the contact portion 92B.

[0133] The contact portion 92C comes into contact with the upper end of the rear wall 23 of the second plate-shaped member 20. As a result, the second plate-shaped member 20 is sandwiched in the front-rear direction between the contact portion 92C and the first surface 30A, and movement of the second plate-shaped member 20 in the front-rear direction is restricted.

[0134] <Ribs 80, 81, 82, 83> The ribs 80, 81, 82, and 83 are an example of a fifth limiting portion. Each of the ribs 80, 81, 82, and 83 protrudes rearward from the first surface 30A and extends in the up-down direction. Each of the ribs 80, 81, 82, and 83 is formed in a plate shape with its thickness direction in the left-right direction. Each of the ribs 80, 81, 82, and 83 does not contact the first surface 30A. Note that each of the ribs 80, 81, 82, and 83 only needs to be out of contact with the first surface 30A at least when the second plate-shaped member 20 is facing it.

[0135] The upper ends of the ribs 80, 81 are connected to the V-shaped wall 44, and the lower ends of the ribs 80, 81 are connected to the bottom wall 29. The ribs 80, 81 are arranged at intervals in the left-right direction. A passage 801 (i.e., a gap) is formed between the ribs 80, 81 to allow the first limiting portion 51 to pass through in the up-down direction.

[0136] The rib 80 contacts the first limiting portion 51 from the right side, thereby restricting the movement of the second plate-shaped member 20 to the right. The rib 81 contacts the first limiting portion 51 from the left side, thereby restricting the movement of the second plate-shaped member 20 to the left. In this way, the ribs 80, 81 restrict the movement of the second plate-shaped member 20 in the left-right direction.

[0137] The upper ends of the ribs 82, 83 are connected to the V-shaped wall 45, and the lower ends of the ribs 82, 83 are connected to the bottom wall 29. The ribs 82, 83 are arranged at an interval in the left-right direction. A passage 823 (i.e., a gap) is formed between the ribs 82, 83 to allow the first limiting portion 51 to pass through in the up-down direction.

[0138] The rib 82 contacts the first limiting portion 52 from the right side, thereby restricting the movement of the second plate-shaped member 20 to the right. The rib 83 contacts the first limiting portion 52 from the left side, thereby restricting the movement of the second plate-shaped member 20 to the left. In this way, the ribs 82, 83 restrict the movement of the second plate-shaped member 20 in the left-right direction.

[0139] <Supplementary information> 9 and 10, an insertion portion 89 that protrudes upward is provided on the upper wall 28 of the second plate-shaped member 20. Meanwhile, the first plate-shaped member 30 is provided with an inserted portion 79 in which an insertion hole 78 into which the insertion portion 89 is inserted is formed. When the second plate-shaped member 20 is moved upward relative to the first plate-shaped member 30, the insertion portion 89 is inserted into the insertion hole 78. Note that the cover of the present disclosure may be configured without the insertion portion 89 and the inserted portion 79.

[0140] The first plate-shaped member 30 is provided with fastened portions 58, 59 each having a fastening hole 57 formed therein. The fastened portions 58, 59 are disposed on the first surface 30A below the second limiting portions 61, 62, respectively. For example, the second plate-shaped member 20 is fixed to the first plate-shaped member 30 by fastening a fastening member (not shown) to the fastening hole 57 of the fastened portions 58, 59 with the fastening member (not shown) passed through the through-hole 48A.

[0141] <Actions according to this embodiment> In this embodiment, the first limiting portions 51, 52 are provided on the lower part of the first surface 30A of the first plate-shaped member 30 (parts below the center in the up-down direction of the first surface 30A).

[0142] Therefore, compared to when the first limiting portions 51, 52 are provided from one end to the other end in the up-down direction of the first plate-like member 30, the area occupied by the first limiting portions 51, 52 in the area between the right wall 24 and the left wall 26 is smaller. This makes it less likely that other components will be hindered from being placed in the area between the right wall 24 and the left wall 26, making it possible to make wider use of the area between the right wall 24 and the left wall 26. This makes it possible to place, for example, reinforcing members such as ribs that reinforce the cover 18, or other components, in the area between the right wall 24 and the left wall 26.

[0143] Furthermore, in this embodiment, the second limiting portions 61, 62 start limiting the movement of the second plate-shaped member 20 in the thickness direction before the limit by the first limiting portions 51, 52 is released.

[0144] Therefore, when the restriction by the first limiting portions 51, 52 is released, the second plate-like member 20 is prevented from moving in the thickness direction, compared to when the second limiting portions 61, 62 begin restricting the movement after the restriction by the first limiting portions 51, 52 is released.

[0145] In addition, in this embodiment, each of the first limiting portions 51, 52 is positioned at a distance from each of the second limiting portions 61, 62 that is at least 1 / 8 of the dimension WA between the right wall 24 and the left wall 26, as shown in Figure 16.

[0146] Therefore, compared to when each of the first limiting portions 51, 52 is positioned less than 1 / 8 of the dimension WA away from each of the second limiting portions 61, 62, movement of the second plate-shaped member 20 in the thickness direction is suppressed in the middle 204 between the right wall 24 and the left wall 26.

[0147] Specifically, each of the first limiting portions 51, 52 is disposed at a position spaced apart from each of the second limiting portions 61, 62 by at least ⅛ and at most ¼ of the dimension WA.

[0148] Therefore, compared to when each of the first limiting portions 51, 52 is disposed at a position that is more than ¼ of the dimension WA away from each of the second limiting portions 61, 62, the following effect is obtained: That is, compared to the above-mentioned case, the limiting function of limiting the movement of the second plate-like member 20 in the thickness direction is smoothly transferred from the first limiting portions 51, 52 to the second limiting portions 61, 62.

[0149] In this embodiment, each of the first limiting portions 51, 52 is disposed at a position that is ⅛ or more of the dimension WA away from the middle 204 between the right wall 24 and the left wall 26.

[0150] Therefore, compared to when each of the first limiting portions 51, 52 is disposed at a position less than 1 / 8 of the dimension WA away from the middle 204, the following effect is obtained: That is, compared to the above-mentioned case, the limiting function of limiting the movement of the second plate-like member 20 in the thickness direction is smoothly transferred from the first limiting portions 51, 52 to the second limiting portions 61, 62.

[0151] Specifically, each of the first limiting portions 51 and 52 is disposed at a position spaced apart from the middle 204 by ⅛ to ¼ of the dimension WA.

[0152] Therefore, movement of the second plate-like member 20 in the thickness direction at the middle 204 is suppressed compared to when each of the first limiting portions 51, 52 is positioned at a position more than 1 / 4 of the dimension WA away from the middle 204.

[0153] In the present embodiment, the first limiting portions 51 and 52 are arranged apart in the left-right direction, which reduces the movement of the second plate-shaped member 20 in the thickness direction in the middle 204 compared to when only one first limiting portion is arranged.

[0154] Specifically, the first limiting portions 51, 52 are disposed at positions spaced apart by at least ⅛ of the dimension WA. Compared to when the first limiting portions 51, 52 are disposed at positions spaced apart by less than ⅛ of the dimension WA, movement of the second plate-shaped member 20 in the thickness direction is suppressed throughout the second plate-shaped member 20.

[0155] In the present embodiment, the first limiting portion 51 has a longer length in the up-down direction than the first limiting portion 52. Therefore, movement of the second plate-like member 20 in the thickness direction is suppressed over a longer range in the up-down direction of the second plate-like member 20, compared to when the up-down length of the first limiting portion 51 is the same as the up-down length of the first limiting portion 52.

[0156] In this embodiment, the protrusions 53 inserted into the notches 42, 43 restrict the movement of the second plate-shaped member 20 in the thickness direction.

[0157] Therefore, by inserting the protruding portions 53 of the first restricting portions 51, 52 into the notches 42, 43, it is possible to restrict movement of the second plate-shaped member 20 in the thickness direction.

[0158] In this embodiment, the opening width of the notches 42, 43 gradually increases toward the upper side. Therefore, compared to when the opening width of the notches 42, 43 is constant toward the upper side, it is easier to insert the protrusion 53 into each of the notches 42, 43.

[0159] In this embodiment, the third limiting portions 71, 72 are provided with insertion portions 73, 74 that are inserted into the notches 42, 43. Therefore, the insertion portions 73, 74 can hide the upper openings of the notches 42, 43.

[0160] 6 , the second limiting portions 61, 62 have contact portions 63, 64 and clamping portions 65, 66. The contact portion 63 contacts the right wall 24, and the contact portion 64 contacts the left wall 26, thereby restricting movement of the second plate-shaped member 20 in the left-right direction. The clamping portions 65, 66 clamp the second plate-shaped member 20 between the right wall 24 and the left wall 26 and the first surface 30A, restricting movement of the second plate-shaped member 20 in the thickness direction. Therefore, compared to a case in which the second limiting portions 61, 62 restrict only movement of the second plate-shaped member 20 in the thickness direction, both movement of the second plate-shaped member 20 in the thickness direction and movement of the second plate-shaped member 20 in the left-right direction are suppressed.

[0161] In this embodiment, the rear surface 20B of the second plate-shaped member 20 is shorter in height in the thickness direction at the rear walls 21 and 23 sandwiched between the sandwiching portions 65 and 66 than at the rear wall 22.

[0162] Therefore, the sandwiching portions 65, 66 are less likely to protrude in the thickness direction from the rear surface 20B of the rear wall 22 compared to when the height in the thickness direction at the rear surface 20B of the second plate-shaped member 20 is constant.

[0163] In this embodiment, the cover 18 is provided with fourth limiting portions 91 and 92 that limit movement of the second plate-shaped member 20 in the front-rear, upward, and left-right directions.

[0164] Therefore, compared to when the cover 18 is provided with only the first limiting portions 51, 52 and the second limiting portions 61, 62, movement of the opposing second plate-like member 20 in the front-rear, upward, and left-right directions is suppressed.

[0165] In this embodiment, the cover 18 is provided with ribs 80, 81, 82, and 83 that restrict the movement of the second plate-shaped member 20 in the left-right direction.

[0166] Therefore, compared to when the cover 18 is provided with only the first limiting portions 51, 52 and the second limiting portions 61, 62, movement of the second plate-shaped member 20 in the left-right direction is suppressed.

[0167] In this embodiment, the ribs 80, 81, 82, and 83 do not contact the first surface 30A of the first plate-shaped member 30. As a result, gaps are formed between the ribs 80, 81, 82, and 83 and the first surface 30A, making it possible to use a wider area between the right wall 24 and the left wall 26 than in a case where the ribs 80, 81, 82, and 83 are always in contact with the first surface 30A.

[0168] <Modification> In this embodiment, the first plate-shaped member 30 is formed from a single plate material whose thickness direction is the front-to-rear direction, but this is not limited to this. The first plate-shaped member of the present disclosure may be a member including elements such as ribs and side walls, or may be a member having a flat shape in the thickness direction. In this embodiment, "plate-shaped" refers to a shape that is flat in the thickness direction, and is not limited to a member formed from a single plate material. The first plate-shaped member of the present disclosure may be a plate-shaped member having a first surface facing the thickness direction.

[0169] In the present embodiment, the second plate-shaped member 20 has rear walls 21, 22, 23, right walls 24, 25, left walls 26, 27, upper wall 28, and lower wall 29, but is not limited thereto. The second plate-shaped member of the present disclosure may have only some of these walls. The second plate-shaped member of the present disclosure may have other walls in addition to these walls. The second plate-shaped member of the present disclosure may be formed from a single plate material, similar to the first plate-shaped member 30. The second plate-shaped member of the present disclosure may be any plate-shaped member having a second surface facing in the thickness direction.

[0170] In the present embodiment, two first limiting portions (first limiting portions 51, 52) are provided on the cover 18, but this is not limited to this. As the first limiting portion of the present disclosure, one or three or more first limiting portions may be provided on the cover 18.

[0171] In the present embodiment, the first limiting portions 51, 52 are disposed in a portion of the second plate-shaped member 20 in the left-right direction between the right wall 24 and the left wall 26, but this is not limited thereto. The first limiting portions of the present disclosure may be disposed, for example, over the entire area between the right wall 24 and the left wall 26.

[0172] In the present embodiment, the first limiting portion 51 has a longer vertical length than the first limiting portion 52. However, this is not limited to this. For example, the vertical length of the first limiting portion 51 may be the same as the vertical length of the first limiting portion 52.

[0173] In the present embodiment, the first limiting portions 51, 52 limit the movement of the second plate-shaped member 20 in the thickness direction and the left-right direction, but this is not limited thereto. The first limiting portions of the present disclosure only need to limit at least the movement of the second plate-shaped member in the thickness direction.

[0174] In the present embodiment, the lower portions of the second limiting portions 61, 62 overlap with the upper portions of the first limiting portions 51, 52 in a side view, but this is not limited to this. The second limiting portions of the present disclosure may be provided above the first limiting portions 51, 52 and spaced apart from the first limiting portions 51, 52.

[0175] In the present embodiment, the second limiting portions 61, 62 start restricting the movement of the second plate-like member 20 in the thickness direction before the restriction by the first limiting portions 51, 52 is released, but this is not limited to this. The second limiting portions of the present disclosure may be configured to start restricting the movement after the restriction by the first limiting portions 51, 52 is released, for example.

[0176] In the present embodiment, the second limiting portions 61, 62 limit the movement of the second plate-shaped member 20 in the thickness direction and the left-right direction, but this is not limited thereto. The second limiting portions of the present disclosure only need to limit at least the movement of the second plate-shaped member in the thickness direction.

[0177] In the present embodiment, the rear surface 20B of the second plate-shaped member 20 is the rear walls 21, 23 sandwiched between the sandwiching portions 65, 66, and has a height in the thickness direction that is lower than the rear wall 22, but this is not limited to this. The second plate-shaped member of the present disclosure may have a configuration in which the height in the thickness direction of the rear surface 20B is constant.

[0178] In this embodiment, as shown in FIG. 16, each of the first limiting portions 51, 52 is disposed at a position spaced apart from each of the second limiting portions 61, 62 by ⅛ or more of the dimension WA, but this is not limiting.

[0180] In this embodiment, each of the first limiting portions 51, 52 is disposed at a position that is ⅛ to ¼ of the dimension WA away from each of the second limiting portions 61, 62, but this is not limiting.

[0182] In the present embodiment, each of the first limiting portions 51, 52 is disposed at a position that is ⅛ or more of the dimension WA away from the intermediate portion 204 between the right wall 24 and the left wall 26, but this is not limited thereto. The first limiting portions 51, 52 of the present disclosure may be disposed at a position that is less than ⅛ of the dimension WA away from the intermediate portion 204, for example.

[0183] In the present embodiment, each of the first limiting portions 51, 52 is disposed at a position that is 1 / 8 to 1 / 4 of the dimension WA away from the middle 204, but is not limited to this. For example, the first limiting portion of the present disclosure may be disposed at a position that is more than 1 / 4 of the dimension WA away from the middle 204.

[0184] In the present embodiment, the first limiting portions 51, 52 are disposed at positions spaced apart by at least ⅛ of the dimension WA, but this is not limiting. For example, the first limiting portions of the present disclosure may be disposed at positions spaced apart by less than ⅛ of the dimension WA.

[0185] In the present embodiment, the opening width of the notches 42, 43 gradually increases upward, but this is not limiting. For example, the opening width of the notches 42, 43 may be constant upward.

[0186] In the present embodiment, the insertion portions 73, 74 to be inserted into the notches 42, 43 are provided in the third limiting portions 71, 72, but this is not limiting. The insertion portions 73, 74 may not be provided in the third limiting portions 71, 72.

[0187] In the present embodiment, the ribs 80, 81, 82, and 83 are configured not to come into contact with the first surface 30A of the first plate-shaped member 30, but this is not limiting. The ribs 80, 81, 82, and 83 may be configured to come into contact with the first surface 30A.

[0188] In the present embodiment, the cover 18 includes the first limiting portions 51, 52 and the second limiting portions 61, 62, as well as the third limiting portions 71, 72, the fourth limiting portions 91, 92, and the ribs 80, 81, 82, 83. However, the present disclosure is not limited to this. The cover of the present disclosure may include at least the first limiting portions and the second limiting portions.

[0189] In the present embodiment, as shown in FIG. 3 , the cover 18 has, as an example, a configuration in which the upper part is opened and closed with the lower part serving as a connection part (specifically, a fulcrum) with the image forming apparatus main body 11, but this is not limited thereto. For example, the cover 18 may have a lower part that is opened and closed with the upper part serving as a connection part with the image forming apparatus main body 11. In this way, the cover 18 can be a cover that is opened and closed vertically. Furthermore, the cover 18 may be a cover that is opened and closed horizontally. Specifically, one of the left and right parts of the cover 18 may be a connection part with the image forming apparatus main body 11, with the other of the left and right parts being opened and closed.
