发明名称 DRIVE DEVICE
摘要 <p>A drive device includes a setting unit 12 for setting a control value using a control value-displacement characteristic at a predetermined reference temperature showing a relationship between a control value used to position a movable unit 5 and a displacement of the movable unit 5; a drive unit 20 for supplying drive power corresponding to the control value set by the setting unit 12 to a shape-memory alloy 1 and causing the shape-memory alloy 1 to expand or contract, thereby positioning the movable unit 5; and a correction unit 13 for correcting the control value so as to correct a position shift of the movable unit 5 from a target position resulting from a difference between a control value-displacement characteristic at an ambient temperature and a control value-displacement characteristic at the reference temperature based on the ambient temperature detected by a temperature detection unit 11.</p>
