Abstract: A hybrid actuator (100A) includes a magnetostrictive actuator (110) having a magnetostrictive element (111), and a moving-coil actuator (130) including a movable portion (132) having an outer periphery to which voice coils (131a), (131b) are attached. The actuator (110) is fixed to the movable portion (132) of the actuator (130) so that the direction of displacement output of a drive rod (113) becomes the same as the displacement direction of this movable portion. Since the actuator (110) is fixed to the movable portion (132) of the actuator (130), together with a displacement output in response to a high-frequency-range audio signal, which is obtained by the actuator (110), a displacement output in response to a low-frequency-range audio signal, which is obtained by the actuator (130), is also obtained at a tip of the drive rod (113). By abutting the tip of the drive rod (113) against an acoustic diaphragm, a wide band audio output can be obtained.

Abstract: An image reading system which, even if a user sets a transparent original of a wrong type in order to obtain a preview image, is capable of displaying the preview image which is suited to the type of the transparent original without executing pre-scanning again. When a film original is set on a scanner and an image is read therefrom to display a preview image, reading of the image is carried out by the same reading method irrespective of whether the film original is negative or positive. Image processing for displaying the preview image is changed according to the type of the film selected by the user.
