PURPOSE:To set the standby position of a photographic lens in a focusing state with reference to the extent of a middle distance and also to move the photographic lens to a focusing position laying at a short distance and a long distance, etc., without using an expensive motor and by having an inexpensive mechanism. CONSTITUTION:Solenoids 60 and 61 are driven by a lens driving device so that an interlocking lever 63 may be rotated to either of set positions; a short distance set position or a long distance set position by a signal from a range- finder circuit 73. A connecting lever 65 is slidden and moved in accordance with the rotation of the interlocking lever 63, so that a front group lens 53 is moved back and forth in an optical axis direction, and then, the photographic lens is made to be in a focusing state with reference to either extent of the short, or long distance. The connecting lever 65 is pressed by a spring 67 when both of the solenoids 60 and 61 are not in driving, so that the photographic lens is made to be in a focusing state with reference to the extent of the middle distance. |
