Opening/closing mechanism
First Claim
1. An opening/closing mechanism comprising:
- a base attached to a main body of an apparatus;
an arm attached to an opening/closing portion of said apparatus and axially supported on said base so as to turn freely;
a rotary plate which turnes together with said arm and which has a projection;
a pop-up plate having an engaging portion, wherein when said opening/closing portion is closed up to a prescribed position, the engaging portion engages with the projection of said rotary plate so that said pop-up plate turns together with the rotary plate; and
a resilient member provided between said pop-up plate and said base and compressed by turning of said pop-up plate, wherein when said opening/closing portion is released, said rotary plate is turned together with said pop-up plate by a compressive reaction force, thereby turning said opening/closing portion up to a prescribed position.
