Abstract: A film scanner is capable of reading an image formed on a film in accordance with a photographing mode recorded in each frame of the film. In this film scanner, an image formed in each frame of a film held by a film holder is projected onto a linear image sensor by a focusing optical system to read the image with the linear image sensor. A magnetic information detection unit detects magnetic information recorded in each frame of the film, and a system controller identifies a photographing mode of each frame of the film. In accordance with the identified photographing mode, an image read area of each frame is set and a subscanning motor is driven in accordance with this image read area. The subscanning motor is driven in the area outside of the image read area at a faster speed than in the image read area. Therefore, a read time can be shortened as compared to the case wherein all frames are read in the broadest image read area. Trimming works can be omitted.

Abstract: An actuator apparatus for applying an electrical signal to an electro-mechanical energy conversion element to form a vibration, and for driving a moving body based on the vibration.When the moving speed of a moving body moved by the actuator apparatus is monitored by, e.g., an encoder, the apparatus detects the encoder output at a timing corresponding to the vibrating state of the actuator, so that an encoder output free from the influence of the vibration can be precisely detected.
