According to this invention, since black regions are provided along the advancing direction on an original plate, the dark-time output levels of the linear sensor would not be affected by dust adhered on the original plate or the presence of trimming lines. Since a calibration region is provided, the circuit system can be calibrated with the maximum and minimum values of the signals from the linear sensor to thereby achieve more precise reading of images.

A liquid crystal shutter array requiring no separate focusing lens system. Microlenses for focusing the light incident upon a matrix of pixel electrodes are formed in a transparent substrate of the shutter assembly. A refractive index of light of each of the microlenses is set in a manner such that the incident angle .theta. of the light incident on the liquid crystal of the shutter through the microlenses satisfies; ##EQU1## where P, a, and d respectively represent the size of each of the photomasks, the length of a portion wherein each of the photomasks and corresponding ones of the pixel electrodes overlap, and the thickness of the transparent substrate on the light output side.

A thermal developing apparatus develops thermally a photosensitive material having an electrically conductive, heat-generating layer. The apparatus is provided with a heat-insulating cover which is disposed in contact with or close to the surface of the photosensitive material when supplied with electric current, whereby the generation of convection of air at the upper side of the photosenstive material is prevented, and the occurrence of uneven development is eliminated. When the heat-insulating cover is disposed at a distance away from the surface of the photosensitive material, if this distance is less than a predetermined value, no convection of air takes place and, hence, there is no risk of uneven development occurring.

A precharge circuit precharges a bit line paired with the bit line to which the selected one of the memory cells is connected, by applying to the former bit line an external reference voltage for comparison with a voltage in the bit line caused by selection of the memory cell. A precharge assist circuit, which is connected to the former bit line in parallel with the precharge circuit, charges the bit line to a predetermined potential by using a power supply voltage. A sense amplifier, which is connected to the pair of bit lines, senses and amplifies a potential of a bit line that is connected to a memory cell selected by word lines.
