PURPOSE:To enable the lens board of a camera to be collapased by a single operation even if a photographing lens is located at any position, by fitting an interlocking member to interlock a lens extending means with a lens barrel collapsing means and collapsing a lens board on a storing position while interlocking with the collapase of the lens barrel. CONSTITUTION:A finder optical system 2 and a range finder 3 are fitted to the upper part of the square box-like body 1 of a camera. The lens barrel 6 supported by upper, lower, right and left folding type barrel collapsing arms 5 is stored in a lens board storing room of the body 1 and protrusively held at the time of photographing. A lens board 8 supported by two upper and lower pantagraph type arms 7 for straight extension is stored in the lens barrel 6. A front ball rotating and extending type photographing lens 15 is attached to the board 8. At the extension of the board 8 by the arms 7, an operation lever 18 is extended and slid by a pin 11, an operation ring 16 is extended and rotated by the lever 18 and the front ball of the lens 15 is simultaneously extended. Consequently, the lens barrel can be collapsed by a single operation even if the lens 15 is located at any position. |
