PURPOSE:To fix both a light emitting element and a light receiving element of a horizontal rotary angle detector and a vertical rotary angle detector of a lens barrel to a stator side member. CONSTITUTION:A slit disk 33 is fitted to a rotor side member of a horizontal rotary angle detector 22 and a vertical rotary angle detector 23 to arrange the slit disk 33 between a light emitting element 25 and a light receiving element 28 arranged opposite to each other and fitted to the stator side member 11 and the slit disk 33 is turned by the rotor side member in a direction orthogonal to an optical axis (f) of the light emitting element 25 as a feature. |
