主权项 1. An image pickup apparatus, comprising: an imaging optical system including at least one optical member; an image pickup device to acquire an object image formed by the imaging optical system; a fixed member provided in a casing at a position fixed relative to an imaging optical axis when seen in a direction perpendicular to the imaging optical axis; a plurality of movable supporting balls, each of the plurality of movable supporting balls being made of a magnetic material and movably supported with attraction of a magnetic force by the fixed member; a movable member in which the image pickup device is provided and which is movable along the imaging optical axis with respect to the fixed member while being supported by the fixed member with the magnetic force through each movable supporting ball; a driving mechanism configured to generate a driving force to relatively move the movable member with respect to the fixed member by utilizing a force which is received by a current from a magnetic field; a display configured to display the object image acquired by the image pickup device; and a mounting plate to mount the display unit in the casing, the mounting plate being provided with a protruding arm portion protruding toward the movable member, wherein the plurality of movable supporting balls are disposed on one side of the movable member, and the protruding arm portion is disposed on another side of the movable member that is opposite to the one side of the movable member.
