摘要： A storing section (70) stores a second initial contact instruction value, which is predefined as an instruction value for positioning a movable portion (5) to a second contact position where the movable portion (5) is contacted with a stopper (8), and an initial standby instruction value, which is predefined as an instruction value for positioning the movable portion (5) to a specified standby position within a moving range of the movable portion (5). A correcting section (42) calculates an actual standby instruction value by correcting the initial standby instruction value, based on a second actual contact instruction value obtained when a contact detection section (41) has detected that the movable portion (5) is positioned to the second contact position, and the second initial contact instruction value. A setting section (43) sets a standby position corresponding to the actual standby instruction value, as an actual standby position of the movable portion (5).

摘要： 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.
