Operations According to Present Exemplary Embodiment
In the present exemplary embodiment, the second rib 42, which protrudes from the facing surface 22 of the internal part 20 and is formed along the up-down direction, is in contact with the first rib 51 in the right-left direction as illustrated in
Here, as illustrated in
In contrast, in the present exemplary embodiment, as described above, since the second rib 42 is in contact with the first rib 51 in the right-left direction, the first rib 51 is supported in the right-left direction in a case where an external force is applied to the exterior cover main body 30. As a result, according to the present exemplary embodiment, in a case where the exterior cover 18 is opened and closed with respect to the image forming apparatus main body 11 or the like, the deformation of the exterior cover main body 30 is suppressed as compared with the case of the mode A.
Further, in the present exemplary embodiment, the first rib 51 is sandwiched between the second ribs 42 in the right-left direction. Therefore, the first rib 51 is supported on both sides in the right-left direction in a case where an external force is applied to the exterior cover main body 30, and the deformation of the exterior cover main body 30 is suppressed as compared with the case where the second rib 42 is in contact with the first rib 51 only on one side in the right-left direction.
Further, in the present exemplary embodiment, the first rib 51 is sandwiched between the second ribs 42 in the right-left direction, but the second rib 42 is not sandwiched between the first ribs 51 in the right-left direction. Therefore, the number of first ribs 51 is reduced as compared with a case where the second rib 42 is sandwiched between the first ribs 51 in the right-left direction.
Here, for example, in a case where the exterior cover main body 30 is formed by injection molding with a resin material, as illustrated in
Therefore, according to the present exemplary embodiment, as compared with the case where the second rib 42 is sandwiched between the first ribs 51 in the right-left direction, the formation of the recess portion 38 on the outer surface 33 of the exterior cover main body 30 is suppressed as a result of reducing the number of first ribs 51 in the exterior cover main body 30.
Further, in the present exemplary embodiment, each of the plurality of second ribs 42 is in contact with each of the plurality of first ribs 51 in the right-left direction. Furthermore, each of the plurality of first ribs 51 is sandwiched between the plurality of second ribs 42 in the right-left direction. Therefore, the deformation of the exterior cover main body 30 is suppressed as compared with a case where only one second rib 42 is in contact with the first rib 51 in the right-left direction.
Further, in the present exemplary embodiment, the fourth rib 44, which protrudes from the facing surface 22 of the internal part 20, is connected to the second rib 42, and is formed along the right-left direction, is in contact with the third rib 53 in the up-down direction as illustrated in
Here, as illustrated in
In contrast, in the present exemplary embodiment, as described above, since the fourth rib 44 is in contact with the third rib 53 in the up-down direction, the third rib 53 is supported in the up-down direction in a case where an external force is applied to the exterior cover main body 30. As a result, according to the present exemplary embodiment, in a case where the exterior cover 18 is opened and closed with respect to the image forming apparatus main body 11 or the like, the deformation of the exterior cover main body 30 is suppressed as compared with the case of the mode B.
In the internal parts 20 in configurations illustrated in
Further, in the present exemplary embodiment, since the third rib 53 is sandwiched between the fourth ribs 44 in the up-down direction, the third rib 53 is supported on both sides in the up-down direction in a case where an external force is applied to the exterior cover main body 30, and the deformation of the exterior cover main body 30 is suppressed as compared with the case where the fourth rib 44 is in contact with the third rib 53 only on one side in the up-down direction.
Further, in the present exemplary embodiment, the third rib 53 is sandwiched between the fourth ribs 44 in the up-down direction, but the fourth rib 44 is not sandwiched between the third ribs 53 in the up-down direction. Therefore, the number of third ribs 53 is reduced as compared with a case where the fourth rib 44 is sandwiched between the third ribs 53 in the up-down direction.
Here, for example, in a case where the exterior cover main body 30 is formed by injection molding with a resin material, as illustrated in
Therefore, according to the present exemplary embodiment, as compared with the case where the fourth rib 44 is sandwiched between the third ribs 53 in the up-down direction, the formation of the recess portion 38 on the outer surface 33 of the exterior cover main body 30 is suppressed as a result of reducing the number of third ribs 53 in the exterior cover main body 30.
Further, in the present exemplary embodiment, each of the plurality of fourth ribs 44 is in contact with each of the plurality of third ribs 53 in the up-down direction. Furthermore, each of the plurality of third ribs 53 is sandwiched between the plurality of fourth ribs 44 in the up-down direction. Therefore, the deformation of the exterior cover main body 30 is suppressed as compared with a case where only one fourth rib 44 is in contact with the third rib 53 in the up-down direction.
Further, in the present exemplary embodiment, a projection portion such as a rib positioned along the up-down direction and a projection portion such as a rib positioned along the right-left direction are not formed on the opposite surface 23 of the internal part 20. Therefore, as compared with the case where the projection portion such as a rib positioned along the up-down direction and the projection portion such as a rib positioned along the right-left direction are formed on the opposite surface 23 of the internal part 20, the roughness on the opposite surface 23 is reduced, thereby the opposite surface 23 is easy to clean in a case where cleaning the opposite surface 23 of the internal part 20 in a case where the exterior cover 18 is opened with respect to the image forming apparatus main body 11.
