摘要： A rotary transformer includes a rotary magnetic member (11a), a stationary magnetic member (11b), and a plurality of coils (13a, 13b, 14a, 14b, 16a, 16b). These two magnetic members have respective counter surfaces opposing to each other with a small space (S) interposed therebetween. A plurality of pairs of coil grooves (12a, 12b) opposing to each other for receiving the plurality of coils on the two counter surfaces are provided. At the same time, a plurality of wiring grooves (18a, 18b) are formed so as to cross the coil grooves to join the same. A pair of lead lines extending from one of the coils (13a, 13b, 14a, 14b) disposed in the coil grooves are drawn out outside of the rotary transformer without crossing other coils simultaneously transferring signals in the wiring groove.

摘要： An imaging apparatus in which the influence of the movement of hands and of the motion of an object to a high resolution picture image is reduced is provided. Picture image light from the object passes through an optical system (33) and light-transmitting domains (L) of a color filter provided at the light incident side of an imaging device (34). The light-transmitting domains (PD) transmit only predetermined chromatic lights of the picture image light to input to corresponding photo-receiving domains (PD) of the imaging device (34). The imaging device (34) is a two-picture element mixed reading type device. In a high resolution mode, an image forming point of the picture image light is moved to two places in parallel and the picture image light is formed at each image forming point to image the picture image light. Then, the signal processing circuit (44) combines the two original picture image signals whose image forming points during the imaging operation are different to generate a single output picture image signal. Thereby, an equivalent imaging time in imaging a single output picture image may be shortened.

摘要： In an image shifting mechanism (10, 100), a pair of bimorph type piezoelectric elements (22a, 22b, 122a, 122b) are disposed on both sides of a refraction plate (21, 121). The bimorph type piezoelectric elements (22a, 22b, 122a, 122b) have a cantilever structure. The base end sides of the bimorph type piezoelectric elements are bonded and secured to a stage (25), and the free end sides are sandwiched between an upper holding plate (23) and a lower holding plate (24) so as to support one end of the refraction plate (21, 121). When the bimorph type piezoelectric elements (22a, 22b; 122a, 122b) are displaced, the refraction plate (21, 121)can be inclined around its rotation center O. In the case of this structure, the specifications of the refraction plate and the bimorph type piezoelectric elements (22a, 22b: 122a, 122b) are determined so that the relationship between the moment of inertia Ic around the rotation center of the moving portions of the image shifting mechanism and the moment of inertia Ig around the center of gravity of the image shifting mechanism is Ic/Ig ≦ 1.6.
