    摘要: A photoelectric conversion array is comprised of a longitudinal semiconductor substrate formed with a plurality of doped regions electrically isolated from one another and equidistantly aligned in the longitudinal direction of the substrate. Each doped region is comprised of a first region containing therein base, collector and emitter regions arranged to constitute a bipolar phototransistor operative in response to irradiation of incident light onto the base region to induce a photoelectric current between the collector and emitter regions, and a second region disposed adjacent to and laterally of the first region and containing therein a drain region, a source region, a channel region between the drain and source regions and a gate region disposed on the channel region to constitute a MOS switching transistor electrically connected in series to the bipolar phototransistor and selectively operative in response to a control voltage applied to the gate region to enable the induced photoelectric current to flow through the channel region to thereby drive the corresponding bipolar phototransistor.

    摘要: The image reading apparatus is of the multi-chip line sensor having a plurality of photoelectric conversion elements connected through corresponding switching elements commonly to every one another. Each group of the commonly connected photoelectric conversion elements outputs on a common line an image signal which is then fed to a sample hold circuit and is thereafter outputted from a single output terminal. By such construction, the image signal from the photoelectric conversion elements is sequentially outputted externally from the single output terminal in the form of output waveshape as held in the sample hold circuit in such manner as to prolong output duration of each bit image signal to thereby enable fast operation of the line sensor.

    摘要: A plurality of opto-electro conversion elements are arranged integrally in a row to constitute a line image sensor to produce respective image bit signals. A plurality of switching elements are connected to the corresponding conversion elements and switchable between on and off states to read out the corresponding bit image signals. A scanning circuit scans sequentially the switching elements to successively turn on them to thereby effect the sequential reading of bit image signals. An initiating circuit is connected to the scanning circuit for generating an initiating signal effective to initiate the scanning circuit. An ending circuit is also connected to the scanning circuit and operates after the switching element of last stage is turned off for generating an ending signal indicative of the ending of scanning operation for one line. A control circuit receives the initiating and ending signals and produces a control signal. A gate circuit is commonly connected to the switching elements and made open according to the control signal to output the series of image bit signals.

A first common line is connected to output terminals of odd-numbered switching elements. A second common line is connected to output terminals of even-numbered switching elements. A first reading gate has an output terminal and an input terminal connected to the first common line. A first reset gate has an output terminal and an input terminal connected to the first common line. A second reading gate has an output terminal and an input terminal connected to the second common line. A second reset gate has an output terminal and an input terminal connected to the second common line. A third common connecting line is connected between the output terminals of first and second reading gates and a signal output terminal for outputting the detection signals. A reset power source terminal is connected to the output terminals of the first and second reset gates. A control circuit operates with the sequential driving of the switching elements for controlling the first and second reading gates and the first and second reset gates so as to output the detection signals while sequentially resetting the photoelectric conversion elements.
