PROBLEM TO BE SOLVED: To solve such a problem that, in a conventional imaging device, an exclusive motor for driving a diaphragm during display of a live view image is required to be provided separately from a motor for driving a shutter.SOLUTION: A drive unit includes: a shutter control cam which is rotated in response to motor drive and transmits a driving force for charging a shutter from the motor to the shutter; and a diaphragm control cam having a first cam surface which is rotated in interlocking with the shutter control cam and transmits the driving force for changing an open state of the diaphragm in a shutter charge completed state where shutter charge is completed from the motor to the diaphragm, and a second cam surface which transmits the drive force for changing an open state of the diaphragm in the open state where an aperture of the shutter is opened from the motor to the diaphragm. |
