BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front cover mounting mechanism suitable for application to, for example, an image forming apparatus.

[0002]

2. Description of the Related Art Conventionally, for example, in the regulation of alignment (gap size between components) when mounting exterior components such as a front cover in an image forming apparatus such as an electronic copying machine, it is largely dependent on mutual precision of components. If the accuracy of the parts is insufficient, the alignment becomes non-uniform and the appearance is deteriorated. For this reason, conventionally, the molds of the parts have been changed several times to adjust the parts with higher accuracy.

Further, instead of changing the mold of the component, another component for regulating the alignment is prepared and the alignment is made uniform by using this component.

[0004]

As described above, conventionally, it was necessary to modify the mold, and it was necessary to prepare a separate component for regulating the alignment, which leads to an increase in the component cost. There is a problem that assembly adjustment becomes complicated due to an increase in the number of parts.

Therefore, it is an object of the present invention to provide a front cover mounting mechanism which can facilitate assembly and adjustment and can achieve uniform alignment while suppressing a request for improvement in accuracy of parts.
