Apparatus including the drive mechanism and a driving mechanism using shape memory alloy

摘要

Driving mechanism using shape memory alloy, the axis of connecting a shape memory alloy the first and second coils to be connected in series with each other in the axial direction (1, 2), each shape memory alloy coil (1,2) drive member pin-shaped extending in the direction (3), the shape memory alloy coil (1, 2) substrate having a (4a) and a drive circuit (11) for supplying a current wiring pattern (4), the drive member ( and a magnetic latch portion for holding a 3) and (9), the magnetic latch part (9) has a latched position in the axial drive member (3), the drive circuit (4a) the shape of the first and second shape memory alloy coil or the second first current to selectively driven memory alloys coils (1, 2), driven (1 , Is fixedly held in the axial direction (9a, 9b) magnetic body drive member (3) is moved along the axial direction 2) by heat shrinking, provided the drive member (3) is magnetically attracted to the latch position is.
