ABSTRACT:
An optical element position control mechanism includes an optical element holding member which holds an optical element of a photographing system; an advancing/retracting movement guide member which guides the optical element holding member in an optical axis direction of the photographing system to be movable in the optical axis direction; and a biasing device including an arm, the arm being swingable about a swing axis which is substantially orthogonal to the optical axis and being engaged with the optical element holding member. The biasing device simultaneously exerts via the arm both a biasing force in a direction of movement of the optical element holding member that is guided by the advancing/retracting movement guide member and a biasing force in a direction orthogonal to the direction of movement of the optical element holding member on the optical element holding member.
