<P>PROBLEM TO BE SOLVED: To provide a lid unit that allows even a large attachment object to be attached smoothly while avoiding that a lid in its opened state becomes an obstacle. <P>SOLUTION: A lid unit 114 includes a lid that performs opening/closing operation via a hinge part 114c with respect to a camera body. The hinge part 114c includes: an opening/closing shaft 1146 that has a protrusion 1146a and rotates according to the opening/closing operation of the lid; a cam member 1148 having a cam surface 1148a on which the protrusion 1146a performs a cam trace; and an energizing member 1150 to energize the cam member 1148 in a direction of the opening/closing shaft 1146. The cam trace of the cam surface 1148a by the protrusion 1146a creates a condition that an energizing force of the energizing member 1150 is exerted on an opening direction of the lid, a condition that the energizing force of the energizing member 1150 is exerted to maintain an opened state of the lid, and a condition that the energizing force of the energizing member 1150 is exerted in a direction in which the protrusion 1146a returns to a second cam region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
