Patent ID: 8653362

Claim:
A cover opening and closing mechanism, comprising: a housing comprising an opening; a cover that is attached to the housing to be rotatable about a predetermined rotation axis so that the cover is movable between a closed position and an opened position, the cover being formed to have flexibility and to be deformable when receiving an external force; a first locking mechanism comprising a pair of members respectively provided at a first position on the cover and at a corresponding position on the housing, the pair of members of the first locking mechanism being brought to a locked state when the cover is in the closed position; and a second locking mechanism comprising a pair of members respectively provided at a second position on the cover and at a corresponding position on the housing, the pair of members of the second locking mechanism being brought to a locked state when the cover is in the closed position, wherein a first distance by which the pair of members of the first locking mechanism slide and move with respect to each other in order to bring the first locking mechanism to the locked state is longer than a second distance by which the pair of members of the second locking mechanism slide and move with respect to each other in order to bring the second locking mechanism to the locked state, and wherein an external force required to cause the pair of the members of the first locking mechanism to slide and move with respect to each other is weaker than an external force required to cause the pair of members of the second locking mechanism to slide and move with respect to each other.
