A driving mechanism is disclosed that utilizes a shape-memory alloy. In particular, mechanical components are movably positioned by a member composed of shape-memory alloy, which changes shape when heated. The present invention reduces the number of mechanical components in a driving mechanism, thereby reducing size and improving performance. One of many applications of the present invention is a camera application.

1. A driving mechanism having a plurality of driven members, comprising:first driving power source; a second driving power source which is a shape-memory alloy member; a transmission changeover mechanism for selectively transmitting a drive force from the first driving power source to a specific one of the plurality of driven members, wherein the transmission changeover mechanism performs a transmission changeover action by utilizing a shape change of the second driving power source; and a controller for controlling electrical power to said first and second driving power sources, wherein said electrical power is supplied to the first driving power source only while said electrical power is removed from the second driving power source.
