Abstract: When a fare is inserted, a receipt on which a password assigned to the user is printed is issued, and a sheets each bearing a printed image is housed in a storage bin or a storage box. When the password printed on the receipt is inputted, the corresponding storage bin (storage box) is shifted to a sheet outlet, thereby allowing the user to take this out. Thus, it is possible to provide a print system that is superior in the operability and allows the user to positively obtain his or her own job, and a sheet-processing device suitable for such a system.

Abstract: A method for measuring the quantity of light emitted from an optical write head which drives an array of light shutter elements extending in a main scanning direction individually in accordance with image data. In order to measure the quantity of light outputted from each of the light shutter elements, a photosensor is moved in the main scanning direction at a constant speed while the light shutter elements are driven in such a way that adjacent elements are not driven at a time. While light shutter elements which are in odd numbers in the array are driven, the photosensor is moved forward to measure the quantities of light outputted therefrom, and while light shutter elements which are in even numbers in the array are driven, the photosensor is moved backward to measure the quantities of light outputted therefrom.

Abstract: 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.

Temperature of the optical shutter array is detected by the temperature sensor, and based on a voltage representing the temperature and a reference voltage for driving optical shutter element, a driving voltage for the optical shutter element is generated in the temperature compensating circuit. The driving voltage is applied to the optical shutter element through the IC control unit and a driving IC. As a result, a voltage applying apparatus for a light signal emitter which has a simple structure and allows cost reduction is provided.

Abstract: 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.

Abstract: The differences in the detected values of temperature and humidity between the time at which the suspension of operation begins and the time at which operation is restored are sought, and the differences are compared with their respective prescribed thresholds. If the difference in temperature is less than the threshold and the difference in relative humidity is less than the threshold, as an example, it is determined that the environmental change during the period of suspension of operation is less than the threshold, and the copying machine is made ready immediately without performing image stabilizing control. On the other hand, where the difference in temperature equals or exceeds the threshold, or where the difference in relative humidity equals or exceeds the threshold, it is determined that the environmental change during the period of suspension of operation equals or exceeds the threshold, whereupon image stabilizing control is executed and the image forming operation parameters are set.
