Claim 9:
10. An actuator comprising:
a control unit configured to allow a first control capable of driving a drive part with a first driving force and a second control capable of driving the drive part with a second driving force which is stronger than the first driving force;
a moving part configured to move in a predetermined direction;
an elastic member configured to receive at least one of the first driving force and the second driving force from the drive part and to supply a force for the moving part to move to the moving part; and
a storage unit configured to store an end condition for ending the second control,
wherein
the control unit starts a first driving of the drive part by the first control, then starts a second driving of the drive part by the second control when the first driving of the drive part has stopped,
the control unit causes the storage unit to store positional information of the drive part as first positional information when the end condition stored in the storage unit has been satisfied, and
a length of the elastic member when the control unit performs the first control is larger than a length of the elastic member when the control unit performs the second control.
