    摘要: A color scanner for converting color data of a color original (e.g., a photographic film) into an electrical signal, includes a level comparator for discriminating the type of film (e.g., color negative vs. color positive, color vs. monochrome, type of color negative) in accordance with output signals, e.g., color component signals, from a sensor (i.e., based on a light transmittance of an unexposed portion of the film). The output from the level comparator is supplied to an accumulation time control block through a register, a selector, and the like. The accumulation time control block corrects the electrical signal based on the discrimination result from the level comparator irrespective of the type of film, so that an accumulation time of the sensor is changed by changing a bias voltage applied thereto.

    摘要: A motor which drives a movable member by a travelling vibration wave generated in a vibration member having electrostrictive elements arranged with a phase difference therebetween is disclosed. The electrostrictive elements are stacked in a lamination direction with the phase difference therebetween so that a contact area between the electrostrictive elements and the vibration member is increased and a high output and high efficiency drive is attained.
