Patent ID: 7916211

Claim:
An imaging apparatus comprising: a camera body including a case, an imaging device accommodated in the case and acting to image a subject, and a signal-processing portion accommodated in the case and acting to create a video signal based on an imaging signal created by the imaging device; a viewfinder unit including a display portion for displaying an image based on the video signal and a frame supporting the display portion; a revolving mechanism for revolving the frame, the revolving mechanism including a detachable plate detachably connected to a detachable portion of the case, a pivot protruding from the detachable plate, and a shaft-receiving hole which is formed in the frame and into which the pivot is rotatably inserted; a frictional mechanism for giving frictional resistance to the frame and maintaining rotation of the frame; and a lock mechanism for locking and unlocking rotation of the frame; wherein the lock mechanism includes a cylindrical member coupled to the pivot so as to be movable along an axial direction of the pivot and having a barrel part which covers the pivot over a part of the frame that is around the shaft-receiving hole, and a manipulating member for locking, the manipulating member being rotatably coupled to the pivot; wherein when the manipulating member is rotated in one direction, the manipulating member moves the cylindrical member toward the detachable plate and the part of the frame around the shaft-receiving hole is held between the front end of the barrel part and the detachable plate; and wherein when the manipulating member is rotated in the other direction, the manipulating member permits the cylindrical member to move away from the detachable plate.
