Abstract: An electric circuit board has a plurality of conductive pads on a base plate for connection with conductive pins of an electric device such as a thermal head of a facsimile machine. Protective parts are formed on the base plate at the right side of the rightmost conductive pad and at the left side of the leftmost conductive pad. The conductive pads and the conductive pins are soldered by solders heated and melted by a light beam. The protective parts protect the base plate from being burnt by the light beam even when the light beam is projected transversely across the pads from the right side of the rightmost pad to the left side of the leftmost pad.

Abstract: An image forming apparatus for irradiating an image light on a photosensitive recording medium having at least one photosensitive wavelength range on the basis of an image information to thereby form an image on the photosensitive recording medium, comprising a semiconductor laser for emitting an image light or a thermal cathode for emitting thermoelectrons having the image information, a photomultiplier or microchannel plate for converting the image light or the thermoelectrons into secondary electrons while the image forming information is kept, and multiplying the secondary electrons, and a fluorescent screen for converting the multiplied secondary electrons into an intensified image light. The intensified image light may be supplied on a photosensitive recording medium while the image forming information is kept, thereby forming an image on the photosensitive recording medium.

Abstract: An image recording apparatus is disclosed which comprises a CRT on which an image produced by an external host computer is displayed. An image recording device records a copy image corresponding to the image displayed on said CRT on a photosensitive recording medium. A control unit controls a CRT driving device corresponding to an aspect ratio data so that the aspect ratio of the CRT is adjusted to that of an external CRT attached to the host computer.

Abstract: In an image recording apparatus for recording an image of an original document on a photosensitive recording sheet, a light source such as a halogen lamp is provided which emits a light and applying it to the image face of the original document while moving the latter. The photosensitive recording sheet is exposed to the resultant image bearing light, in which the photosensitive recording sheet is moved at a speed equal to the moving speed of the original document. A light intensity sensor detects the intensity of the light applied to the original document, and when the intensity of the light applied thereto is lowered than a required level, the moving speeds of both the photosensitive recording sheet and the original document are lowered to thereby maintain an exposure rate at substantially constant.

Abstract: Input data on a colored or monochromatic image having a gradation are recorded on a light transmissive sheet to prepare mask originals. The data on the colored image are separated into data corresponding to red, green and blue color components and the data on each of the color components are converted to dither data. At least two mask originals are prepared for each color on the basis of the dither data associated with the color. Photosensitive pressure-sensitive recording paper coated with microcapsules each encapsulating a chromogenic material is exposed to light through the mask originals and is then subjected to development under pressure, whereby the image is reproduced thereon. The mask originals carry at least two different patterns of image data for each color.

Abstract: A copying apparatus operable with an original having an image-bearing surface on which images to be reproduced are supported. A radiation reflected by the image bearing surface is focused on a photosensitive paper, by a self-focusing lens array, so that latent images corresponding to the images on the image-bearing surface are formed on the photosensitive paper. The latent images are developed into visible images by a developing device such as a device adapted to apply a pressure to the photosensitive paper. The photosensitive paper may be a self-activated type having a photosensitive material and a developer material which chemically react with each other in the developing process. Alternatively, a separate developer paper having a developer material is superposed on a photosensitive paper having only a photosensitive material.
