Abstract: PURPOSE:To directly detect the movement of a moving member of a lens by operating the position of the moving member to a fixed member with use of detecting outputs of a position detecting means of a rack and pinion adjustment and a position detecting means of a fine adjustment. CONSTITUTION:When a moving frame (moving member) 2 is moved in a direction of an optical axis by a linear ultrasonic motor USM, a second mask member 22 integral with the moving frame 2 is moved to a first mask member 21, so that since waves are magnified a/DELTA times the moving amount of the moving frame 2 and moved on a photoreceptor 24b. The movement of the distribution of the quantity of light is detected by the photoreceptor 24b for fine adjustment. Moreover, a light from a light emitting body 23 passing through a through-hole 22b of the second mask member 22 casts a spot on a photoreceptor 24a for coarse adjustment. Therefore, the moving amount of the moving frame 2 is directly detected as the moving amount of the spot of light on the photoreceptor 24a. In this manner, the detecting outputs for coarse adjustment and fine adjustment are operated and the position of the moving frame 2 to a fixed frame (fixed member) 1 is detected.
