Imaging apparatus and lock mechanism
First Claim
1. 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 includesa cylindrical member coupled to the pivot so as to be movable axially 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, anda 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.

Abstract
An imaging apparatus is disclosed. The image apparatus has: a camera body; a viewfinder unit including a frame; a revolving mechanism for revolving the frame; a frictional mechanism including a detachable plate and giving frictional resistance to the frame and maintaining rotation of the frame; and a lock mechanism for locking and unlocking rotation of the frame. The lock mechanism includes a cylindrical member and a manipulating member for locking. When the manipulating member is rotated in one direction, the manipulating member moves the cylindrical member toward the detachable plate. The part of the frame around a pivot-receiving hole is held between the front end of a barrel and the detachable plate. When rotated in the other direction, the manipulating member permits the cylindrical member to move away from the detachable plate.

18. A lock mechanism mounted in a revolving mechanism for revolving a frame, the revolving mechanism having a detachable plate, a pivot protruding from the detachable plate, and a shaft-receiving hole formed in the frame, the pivot being rotatably inserted in the shaft-receiving hole, the lock mechanism acting to lock and unlock rotation of the frame, the lock mechanism comprising:
-
a cylindrical member coupled to the pivot so as to be movable axially of the pivot and having a barrel part that 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. - View Dependent Claims (19)
