摘要： A lens barrel, an image pickup apparatus, a lens drive method and a method of producing a shape memory alloy used for the drive device are disclosed. A drive device includes: a lens group for guiding light from a subject; a shape memory alloy adopted to be deformed by an electricity supplied to the shape memory alloy, for moving the lens group in a direction of an optical axis; and electricity-supply controlling means for controlling an amount of the electricity supplied to the shape memory alloy; and a detecting means for detecting whether a movement of the lens group starts or not. In the drive device, a movement amount of the lens group in the direction of the optical axis is controlled based on the amount of electricity supplied when the detecting means detects the movement of the lens group.

摘要： The present invention concerns a camera incorporating a real-image finder, having a structure more compact than ever. The camera includes an objective optical system; an erect-image optical system, having a reflecting surface, to receive a light bundle passed through the objective optical system; and an ocular optical system to receive the light bundle reflected from the reflecting surface of the erect-image optical system. In the camera, a rear end of the reflecting surface is located at a backward position with respect to a film conveyance surface and outside the film conveyance surface, and, a front end of the reflecting surface is located at a forward position with respect to the film conveyance surface and inside the film conveyance surface.
