Further, the digging type handle portion 15 is formed of a resin integrated body using plastic when manufacturing an exterior member 11a (in the example of FIG. 1, an exterior cover on the right side rear surface) constituting a part of the exterior 11. The outer member 11a is formed by molding.

Since this digging type handle is normally provided for the purpose of lifting the device by placing a hand during transportation, the frame of the structure 6 constituting the skeleton of the casing is formed on the upper part on the back side of the handle part 15. The reinforcing material 14 fixed to the frame abuts and receives a load on the frame side, and the reinforcement in the lifting direction (upward direction) is performed.
Here, FIG. 5 is a cross-sectional view of the main part of the section of the housing of the image forming apparatus 1 shown in FIG. 1 provided with the digging type handle, as viewed from the rear side of the apparatus, and the digging type according to the present invention. In the handle, as shown in FIGS. 4 and 5, a U-shaped reinforcing material 14 is disposed at a position facing the upper part on the back side of the handle portion 15 of the exterior member 11a, and this reinforcing material 14 is attached to the casing. It is fixed to the frame of the structure 6 with a fastening member or the like. 6 is a perspective view of the main part of the structure 6 where the reinforcing member 14 is fixed obliquely viewed from the rear, and FIG. 7 is a main part of the structure 6 where the reinforcing member 14 is fixed viewed from the right side. FIG. In the example shown in FIGS. 5 to 7, since both ends of the reinforcing member 14 are fixed to the frame of the structure 6 with fastening members (for example, bolts and nuts), the upward load that the reinforcing member 14 receives from the handle portion 15. Can be received by the frame of the structure 6.

  Incidentally, the digging type handle provided in a part of the exterior 11 of the image forming apparatus 1 is provided for the purpose of lifting the apparatus by placing a hand during transportation as described above. In addition, the user may move by dragging the device. In such a case, if the handle portion 15 is not reinforced in the drag direction (lateral direction), the exterior surface may bend and be damaged when a load is applied in the horizontal direction.

  Therefore, in the present invention, as shown in FIG. 5, a reinforcing member 14 is provided that is disposed at a position facing the back side upper portion 15a of the handle portion 15 of the exterior member 11a and is fixed to the frame of the structural body 6 of the housing.

Thus, by providing the rib 13 engaged with the reinforcing material 14 on the back surface side upper portion 15a of the handle portion 15, the rib 13 can be engaged with the reinforcing material 14 and the lateral load can be received by the reinforcing material 14. More specifically, the reinforcing member 14 receives an upward load applied to the upper portion of the handle portion 15 of the exterior 11 and receives a lateral load applied to the handle portion 15 by engaging with the rib 13 of the handle portion 15. As a result, the load applied in the upward and lateral directions can be received by the reinforcing member 14 on the frame side of the structure 6, and problems such as damage to the exterior surface can be solved.

  Here, in the digging type handle of the present invention, as shown in the schematic cross-sectional view shown in FIG. 2, a slight gap d between the back side upper portion 15 a of the handle portion 15 and the reinforcing material 14, for example, 0.5 mm to When the gap d of about 1.5 mm is provided and the apparatus is moved, the handle portion 15 bends and the back side upper portion 15a of the handle portion comes into contact with the lower surface of the reinforcing member 14 and the rib 13 engages with the reinforcing member 14. The reinforcing material 14 receives the upward and lateral loads on the handle portion 15. As a result, even if a slight gap d is provided between the back side upper portion 15a of the handle portion 15 and the reinforcing member 14, the load applied in the upward and lateral directions can be received by the reinforcing member 14 on the frame side. Problems such as surface breakage can be solved. In addition, by providing a slight gap d between the back side upper portion 15a of the handle portion 15 and the reinforcing member 14 in this way, positioning is performed when the exterior member 11a provided with the handle portion 15 is assembled to the housing. The degree of freedom increases, positioning becomes easier, and assembling improves.

  Next, FIG. 3 is a perspective view of a main part on the back surface side of the exterior member 11a provided with the handle portion 15 of the digging type handle. As shown in FIGS. 2 and 3, in the exterior member 11 a having the handle portion 15 according to the present invention, a rib that is engaged with the reinforcing member 14 fixed to the frame side of the housing on the back side 15 a of the handle portion 15. 13 and a positioning projection 12 for engaging with retaining holes 18 and 19 provided on the frame side of the housing as shown in FIG. 4 is provided on the back side above the handle portion 15. As a result, by engaging the hooking protrusions 12 with the hooking holes 18 and 19 provided on the frame side of the housing, the exterior member 11a can be positioned and temporarily fixed, and the assembling property is improved. More specifically, when the exterior member 11a is attached to the housing, after the rib 13 of the upper surface 15a on the back surface side of the handle portion 15 is engaged with the reinforcing member 14 fixed to the frame side of the structural body 6 of the housing. The positioning member 11a can be positioned and temporarily fixed by engaging the hooking protrusions 12 and 19 provided on the frame side of the structure 6 with the hooking protrusions 12 for positioning using the deflection of the outer surface. Assembling performance is improved.

  More specifically, when the rib 13 that engages with the reinforcing member 14 is provided on the back side 15a of the handle portion 15 of the digging type handle, when the rib 13 is engaged with the reinforcing member 14 on the frame side, It is necessary to assemble the handle 15 of the exterior member 11a so that the handle 15 of the exterior member 11a is placed under the reinforcing member before the positioning projection 12 is hooked on the retaining holes 18 and 19 on the frame side. By utilizing the deflection, the handle portion 15 of the exterior member 11a can be easily assembled to the lower side of the reinforcing member 14 of the frame. Specifically, when assembling the exterior member 11 a to the housing structure 6, first, the handle portion 15 of the exterior member 11 a is placed below the reinforcing material 14 and provided on the back side upper portion 15 a of the handle portion 15. The rib 13 is assembled so as to be hooked on the frame-side reinforcing member 14. At this time, the hooking protrusion 12 for positioning the exterior member 11 a is in contact with the frame of the structure 6. If the vicinity of the protrusion 12 is bent in the bending direction (the direction of the arrow 16 shown in FIG. 2), the rib 13 can be easily engaged with the reinforcing member 14 on the frame side, and the handle portion 15 can be easily moved. Can be assembled. Then, after assembling the handle portion 15, the lifting projection 12 and the retaining holes 18, 19 provided on the frame side of the structural body 6 so as to return the deflection of the exterior member 11 a while lifting the exterior member 11 a upward. By positioning and engaging the hooking protrusions 12 with the hooking holes 18 and 19, the exterior member 11a can be easily positioned and temporarily fixed. If the exterior member 11a is positioned and temporarily fixed in this manner, the exterior member 11a is temporarily fixed to the structure 6 side by the hooking projection 12, so that the hand can be released from the exterior member 11a, screwing, etc. Thus, the work of fixing the exterior member 11a to the structure 6 can be easily performed. 8 shows a state in which the exterior member 11a having the handle portion 15 is assembled to the portion of the structure 6 shown in FIG. 4 to which the reinforcing member 14 is fixed.

By the way, in the exterior member 11a having the shape as shown in FIGS. 1, 2, 3 and 8, the exterior member 11a is bent when the hooking protrusion 12 for positioning is inserted into the retaining holes 18 and 19 on the frame side. Therefore, if the reinforcing member 14 is designed to always contact in the lifting direction (upward direction) of the digging type handle, the positioning position in the lifting direction (upward direction) is the upper part of the handle portion 15 and the hooking protrusion 12. There is a problem that positioning is lost, the degree of freedom of positioning is lost, and positioning of the exterior member 11a is difficult. Therefore, as described above, if a slight gap d (about 0.5 mm to 1.5 mm) is provided between the back surface side upper portion 15a of the handle portion 15 of the exterior member 11a and the reinforcing member 14, the handle portion is obtained. When the exterior member 11a provided with 15 is assembled to the casing, play of about 0.5 mm to 1.5 mm can be performed in the upward direction, the degree of freedom in positioning is increased, and the positioning position in the lifting direction (upward direction) is a hooking projection. Since it becomes only 12 side, it becomes easy to position the exterior member 11a.
Even if a slight gap d is provided between the back surface side upper portion 15a of the handle portion 15 of the exterior member 11a and the reinforcing member 14 in this way, the gap d is about 0.5 mm to 1.5 mm. When a load is applied to the handle portion 15, the handle portion 15 bends in the direction indicated by the arrow 17 in FIG. 2 to absorb a distance of about 0.5 mm to 1.5 mm of the gap d, and the back side of the handle portion 15. The upper portion 15a abuts on the reinforcing member 14, and the rib 13 engages with the reinforcing member 14 so that the reinforcing member 14 can receive the upward and lateral loads applied to the handle portion 15. Thereby, the safety | security of the handle part 15 is not impaired at the time of conveyance and movement of an apparatus, and problems, such as damage of an exterior surface, can also be eliminated.

In addition, in the housing | casing which concerns on this invention demonstrated above, the exterior member 11a which provided the digging type handle part 15 by using the exterior member 11a which has said digging type handle in at least two places of an exterior. Positioning and assembling can be improved. In addition, since the handle portions 15 of at least two exterior members are reinforced against loads in both the lifting direction (upward direction) and the pulling direction (lateral direction), damage to the handle portion 15 and the exterior member 11a is prevented. A housing having a prevented structure can be realized.
