OBJECT OF THE INVENTION
[Industrial application fields]
The present invention relates to an attachment mechanism for attaching another member to a plastic attachment member.
[0002]
[Prior art and problems to be solved]
Currently, plastic articles are flooding society, but unlike natural materials such as wood and metal, plastics are often difficult to return to the so-called “return to earth” state. As is well known, a member having a high strength such as a metal is widely used in such a portion.
[0003]
For this reason, from the viewpoint of saving resources, that is, from the viewpoint of recovering discarded plastics and returning them to raw materials through the process of pulverization and melting, metals that have been incorporated in plastic products until then. However, the auxiliary member is inevitable that the regeneration process becomes difficult.
[0004]
Such an actual situation will be briefly described with reference to an image forming apparatus shown in FIG. This figure is a schematic side view of the image forming apparatus. The image forming apparatus can be opened and closed around the fulcrum 3 on the front side of the apparatus main body 1 and on the position where the operator stands. A cover 2 is provided for this purpose.
[0005]
At the inner position of the cover 2, there are provided an apparatus main body side inner cover 5 and an opening / closing band 4 attached to the cover 2 side by screws 7, and the cover release amount is regulated to drop off or break. Etc. are prevented. When the cover 2 is closed, the magnet catch 8 attached to the cover 2 is attracted to the magnet catch plate 6 attached to the inner cover 5, and the cover 2 is fixed at the closed position.
[0006]
“FIG. 8” shows that the band 4 is attached to the inner cover 5 with screws 7, and “FIG. 9” shows that the magnet catch plate 6 for maintaining the cover 2 in the closed state is fixed. It is sectional drawing.
[0007]
Referring to FIG. 8, when the cover 2 is released as shown in FIG. 7, a force as indicated by F ₁ is applied to the cover 4. In order to face this, a bit 9 of M3 to M4 is usually fixedly arranged on the inner cover 5, and a band 4 is fixed by screwing a screw 7 thereto. In order to prevent the bit 9 from falling off from the inner cover 5, a knurling is usually engraved around the bit 9.

[Means for Solving the Problems]
Therefore, the present invention has a first support member that supports one end side of the coupling member, and a second support member that supports the other end side of the coupling member, and is capable of being attached to and detached from the coupling member. When the coupling member is detached from the coupling member, the movement of the coupling member in a direction in which the member to be coupled is detached from the coupling member is restricted, and one end side of the coupling member is supported to detachably support the coupling member. In a cover for covering a device having a first supporting member and a second coupling member that supports the other end side, and a regulation unit that regulates movement of the coupling member in a direction perpendicular to the direction, There is a hole for inserting a tool to apply a force in the said direction from the surface opposite to the surface on which the coupling member is attached in order to remove the member from the cover. Set at a position outside the range between the two support members. It allows to solve the above problems have been.
[0012]
By configuring in this way, the entire configuration of the predetermined part of the device can be formed from a single material, which is effective for the recycling process of the material after use.
