PROBLEM TO BE SOLVED: To take an in-focus photograph by simply and accurately performing range-finding for close-up photographing by moving the focal position of a photographing lens to a position including the object of distance nearly equivalent to the extended quantity of an extending member capable of being extended on the side of the object from a camera front surface by manual operation at the inside of the depth of field. SOLUTION: The extending member 11 is wound on a take-up shaft 12, and the other end of a string 25 whose one end is attached at a pin 251 implanted at a lens moving can 23 is wound on the take-up shaft 13 integrally rotating with the take-up shaft 12. The extending member 11 is maintained in a shortest projecting state from the front surface 10 of a camera 1 by the spring force of a rotary shaft spring 15 inserted into a common rotary shaft 14 integrally coupling the take-up shafts 12 and 13 and a can spring 232 hung between the lens moving can 23 and a camera main body. Then, the lens moving can 23 moves the focal position of the photographing lens 21 at the position so as to enter the inside of the depth of field of the object of the distance nearly equal to the extended quantity of the extending member 11. |
