Abstract
A drive unit and drive module which use a shape memory alloy as a drive source to move a driven member, and which can drive at a high speed, independently of the ambient temperature and the position of the driven member. The timing of moving the driven member is controlled based on the position to which the driven member is moved, and based on the settling time for the driven member moved to that position to settle at that position, thus, the driven section can be moved in the minimum drive time, and this arrangement provides the drive unit and drive module that can drive at a high speed, independently of the ambient temperature and the position of the driven member.
