摘要： A light shutter device which has a plurality of light transmitting portions (light shutter elements) on a planar PLZT substrate. By applying voltages between a common electrode and individual electrodes to apply electric fields to the light shutter elements, the light shutter elements transmit and shut light individually. Suppose each of the individual electrodes faces the common electrode at a distance L and has a dimension W in a direction perpendicular to the direction of electric field, W/L>2. Suppose each of the individual electrodes has a dimension D in the direction of electric field, preferably D/L>0.5. Further, the individual electrodes are so placed that the distance between a side of one light shutter element which extends in a direction perpendicular to the direction of electric field and each of the individual electrodes which drive the other light shutter elements is not less than 5L.

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.

摘要： In a light shutter device in which multiple light shutter elements are located on a substrate made of PLZT, and the ON/OFF control of light is carried out by having an electrical field operate on each light shutter element from a pair of electrodes, the cross-talk phenomenon occurs among adjacent elements on the PLZT substrate, i.e., the elements (13c), (13e) and (13g). In order to effectively prevent such cross-talk, driving is carried out such that an electrical field does not operate on such elements simultaneously as a practical matter. In other words, the one line cycle is divided into periods (a) and (b), and the element (13e) is turned ON during the period (a) while the other elements (13c) and (13g) are turned ON during the period (b). Through this operation, a light shutter device in which each element has a stable amount of pass-through light may be obtained.

摘要： A recording apparatus has both a copier function and a fax printing function. The recording apparatus is provided with a photoconductive member, an original table on which an original is placed, and a scanner for scanning the original placed on the original table to project an image of the original onto the photoconductive member so that an electrostatic latent image may be formed on the photoconductive member. An optical print head is provided for forming an electrostatic latent image on the photoconductive member based on an electric signal. Accordingly, the recording apparatus has two modes, a copy mode in which an electrostatic latent image is formed by an operation of the scanner and a print mode in which an electrostatic latent image is formed by an operation of the optical print head. A plurality of sensors are provided for detecting the operation of the scanner, which is controlled by a controller in each of the copy mode and the print mode. The electrostatic latent image formed on the photoconductive member is transferred as a visible image on a recording medium by a transfer unit.
