Abstract: An electronic image filing system includes a reader for reading desired information from a first storage medium containing a plurality of information, a storing device for storing the image read by the reader into a second storage medium, and a controller for controlling the store operation of the storing device. The image on the first storage medium can be retrieved by either the controller or the reader. Following information can be retrieved before the information read by the reader has been stored into the second storage medium.

Abstract: There is disclosed an image processing system capable of effectively utilizing a large-sized display unit by expanding the image signals to be displayed.

Abstract: There is disclosed an image processing system composed of a network of plural stations, in which the transmitted image signals can be monitored on real time basis, always utilizing the full image display area and without lack in the displayed image, by suitably converting the image signals.

Abstract: An image processing system has an original reader or an image file for generating an image signal, a soft display, a high-speed printer, a small printer, a work station with a CPU, and a switching device. An image can always be displayed or printed at the center of a display surface or of a recording medium irrespective of a difference in the image and the display surface or recording medium.

Abstract: An image processing apparatus comprises binarizing circuit for binarizing an input image data, selector for selecting a transmission destination of the binary signal from the binarizing circuit, and switching device for switching a binarization mode of the binarizing circuit in accordance with the selection by the selector.

Abstract: There is disclosed a display apparatus in which plural erasable images formed on an image bearing member are transported to display mechanism and displayed simultaneously thereon. The image bearing member moves along a determined path, along which provided are stations for image formation, display and erasure. The plural images on the image bearing member are selectively changeable.

Abstract: An image processing system transmits image information in the form of electrical signals among plural stations for processing. A switching unit is provided to supply plural sets of signals to the plural stations in a parallel manner, thus achieving efficient signal transmission.

Abstract: Exposure control apparatus for use in a duplicating machine includes a light source powered with a high-frequency pulsed voltage to generate light, a sensor for sensing intensity of the light to produce a sensor output, and control circuitry for controlling the on/off timing of the pulsed voltage in response to the sensor output. At the time of initial turn-on of the lamp the power applied to such lamp is supplied at an increased rate to hasten the turn-on time.

Abstract: A copying apparatus has a manual insertion paper feeding mechanism having a manual insertion portion discrete from an insertion portion through which normally used paper may be inserted for conveyance thereof, register device for once stopping paper inserted through the manual insertion portion and thereafter conveying the paper at an adjusted timing, and slip feeder provided between the manual insertion portion and the register device for effecting forward feeding of the paper inserted through the manual insertion portion and for effecting slip feeding of the paper while maintaining the forward feeding condition when the forward movement of the paper is stopped by stoppage of the register device.

Abstract: A high-voltage power source for suppling a high voltage to corona dischargers used with an electrophotographic apparatus, wherein plural connectors to be connected to the plugs of said corona dischargers are integrally mounted on a casing of a transformer and are connected to the output terminals of said transformer without high-voltage cable thereby eliminating the noise conventionally generated by such high-voltage cable and simultaneously achieving economization of the space and cost required for said cable and the conventionally used separate connectors.
