摘要： The disclosure is directed to an image recording arrangement for use in facsimile equipment and the like, adapted to effect an image recording at a rough density for standard information and an image recording at high density for fine information at a density at least two times that of the rough density. The recording arrangement includes a recording head having a dot density sufficient to resolve the high density so that, during the recording at the rough density, one bit of the recording information corresponds to at least two dots of the recording head.

摘要： A data converter is provided with arranged in a parallel manner such that each has a storage capacity for plurality of bits. A counter counts clock pulses and supplies a signal representing the counting results to a decoder, which in turn supplies loading pulses to respective shift registers. The shift registers received in a parallel manner a plurality of serial bit data in response to the loading pulses and internally transfer the storage contents bit by bit in response to transfer signals, so that the data read from the shift registers are outputted through an output control gate.

摘要： An apparatus for reading an image from a document which comprises a light emitting means having a plurality of LEDs, a back plate disposed in the vicinity of a region in which the document is to be irradiated, an optical sensor, an adjust means which changes the output level of each LEDs, and a control means which controls the adjust means in such a manner that the output level of each of the LEDs is equal to each other, in response to the output signals of the optical sensor which are obtained from light beams reflected from the back plate when no document is in the region. In the apparatus, the document can be irradiated uniformly by the LEDs.
