ABSTRACT:
A camera in which a photographing lens tube is movable between a collapsed position assumed in a non-photographing condition and an extension position assumed in a photographing condition. The camera is provided with a barrier swingingly rotatable through a hinge between a fully closed position at which the barrier covers a front surface section of a photographing lens and further to take a fully open position at which the barrier retreats from the photographing lens. The barrier is biased in a closing direction when it is in a fully closed position side relative to a substantially middle position between the fully closed position and the fully open position, while being biased in an open direction when being in a fully opening position side with respect to the substantial middle position. With a power switch being switched from its OFF state to its ON state, the barrier is shifted from the fully closed position to the fully open position in conjunction with the movement of the photographing lens tube from the collapsed position to the extension position.
