摘要： When a fixing roller 1 generates heat by a magnetic flux generating section 3 during a standby time, a control section 5 rotates the fixing roller 1. This prevents the fixing roller 1 from locally generating heat and being damaged. Moreover, the control section 5 rotates and heats a pressure roller 2 during the standby time, which makes it possible to keep the pressure roller 2 at a specified temperature and to reduce a time taken for a fixing device to recover from the standby state.

摘要： An image forming apparatus which comprises a light shutter disposed between a source of light and an image carrier, which is electrostatically charged to a predetermined polarity, and capable of exhibiting a light transmissivity which varies according to a voltage applied to the light shutter. A first voltage of a predetermined direction is applied to the light shutter according to image information during a first period in which a first area of the image carrier passes across the light shutter, to form the electrostatic latent image on the image carrier. This electrostatic latent image is subsequently developed into a toner image. In order to substantially recover the light shutter from a light-induced fatigue, i.e., internal polarization of an electro-optical material forming the light shutter, a second voltage of a direction counter to the predetermined direction is applied to the light shutter during a second period in which a second area of the image carrier passes across the light shutter.

摘要： A light shutter device including a group of light shutter elements 31a, 31b 31c and 31d formed on a light shutter chip 30 made of PLZT has a construction in which an electrode gap is set wider in a element in which an electric field acts more strongly to equalize half wavelength voltages of elements almost to the same level since electric fields acting on the elements are different in strength from each other even under a prescribed voltage applied between a common electrode 32 and each of individual electrodes 33. An electrode gap of an element 31c having a weaker electric field is comparatively set narrower, whereas an electrode gap of an element 31d having a stronger electric field is set comparatively wider. Moreover, a shape of electrodes of each element are altered so as to make half wavelength voltages of elements almost equal.

摘要： A liquid crystal panel displays an image, while a lens projects, as a virtual image, an image displayed by the liquid crystal panel. A control system controls either the liquid crystal panel or the lens so as to periodically effect a changing of the position of the virtual image, each changing occurring over a predetermined time period. The control can be accomplished by changing the position of the liquid crystal panel or of the lens along an optical axis at a speed of less than 0.1 mm/sec so as to avoid burdening the eye of the observer. The motion can be at a uniform speed through most of the range of the motion, while permitting a slowing down to a stop at each end of the range and then an acceleration to the uniform speed in the opposite direction. A rest period (i.e., a full stop for a period of time) can be provided at one or both ends of the motion range, either for each cycle of motion or after the occurrence of a plurality of such cycles. When used in a situation in which the size of the viewed image is of particular importance, the size of the display region can be changed so that the apparent image size remains constant with a change in the position of liquid crystal panel.

摘要： An optical shutter device wherein a light emitted from a light source is allowed to be incident to a polarization shutter chip through a fiber array and then the light is caused to pass through the chip by turning on a voltage to be applied to electrodes connected to transmittable portions corresponding to pixels, so that a receptor surface is lighted through an imaging lens array. Light which is incident to the polarization shutter chip at an angle .theta..sub.0 is reflected from electrode vertical surfaces, and then the light outgoes from the transmittable portions in the form of leakage light. However, the aperture angle of a lens unit of the imaging lens array is set smaller than the incident angle .theta..sub.0, and thus the light (which were incident) at the angle .theta..sub.0 (leakage light) is not focused on the receptor surface by the lens unit.
