ABSTRACT:
In a collapsible barrel type camera according to the present invention, when the camera user tries to move a barrier from an opened position to a closed position when a lens barrel is protruding to a photographing position, a barrier clicking portion generates a resistance to the barrier before the barrier makes contact with a side of the lens barrel to urge the user to wait for the closing operation. A barrier switch turns off immediately before the barrier has moved to that position where it receives the resistance, and the lens barrel thereby retracts. Hence, the photographer can fully close the barrier after he or she has confirmed collapse. Further, in this camera, the provision of a complicated locking mechanism is not required between the barrier and the lens barrel. This makes the camera compact.
