PURPOSE:To eliminate the mechanical interlocking mechanism such as a roll- out mechanism of a photographing lens, etc. and to make a camera small-sized, by making a member fixed to a projecting element transferrable directly to the place near a distance mark in a viewfinder. CONSTITUTION:An IRED11, i.e., a projecting element is in focus of a projecting lens 5 at the position shown by a solid line to an infinite subject, and then shifted by pivoting on a fulcrum axis 9 via a lever 8. In this case, a frame plate is set at the rear side of a camera. Thus it is possible to set the distance B from the axis 9 to the tip 8a of an IRED lever which is a pointer larger than the distance A from the axis 9 to the IRED11. The IRED lever serves as a poiner 8a. Thus the moving degree of the pointer 8a can be increased. Accordingly, the mechanical interlocking mechanism like a roll-out mechanism of a photographing lens, etc. is eliminated and the camera can be made small-sized. |
