发明名称 Optical apparatus
摘要 An apparatus, such as an image pickup apparatus, includes a first optical unit constituting part of an optical system, a first motor which drives the first optical unit, a second optical unit disposed behind the first optical unit and constituting part of the optical system, a second motor which drives the second optical unit, and a control device which controls the first motor and the second motor in such a way as to draw in the second optical unit in response to an instruction for stowing the optical system and draw the first optical unit into a space made vacant by drawing in the second optical unit. Thus, the control device controls the first motor in such a way as to draw the first optical unit into the space after the space is made vacant by drawing in the second optical unit.
