Patent ID: 7970312

Claim:
An image forming apparatus, comprising: a main body having an opening therein to provide access to an interior thereof; an openable/closable cover panel to cover the opening of the main body; a unitary assembly detachably attached to an inner side of the cover panel to settle into an operational position within the main body of the image forming apparatus by contacting the interior of the main body as the cover panel closes; a fastener to fasten the assembly in place on the cover panel; and a holder to hold the assembly on the cover panel, the holder including: a positioning surface to receive a positioning pin projecting from the assembly; and first and second guide surfaces disposed on opposite sides of the positioning surface each to slidably guide the positioning pin onto the positioning surface, the second guide surface being elastically displaceable to cause the positioning pin to slide off onto the positioning surface as the positioning pin presses against the second guide surface due to pressure acting on the assembly against the cover panel.
