    摘要： The first and second electrodes, to which a recording signal is to be applied, are printed to a desired pattern on an insulating substrate by, for example, a screen printing method. A heating resistor is formed by, for example, a screen printing method so as to be bridged over these first and second electrodes. A protective layer is formed so as to cover the first and second electrodes and heating resistor therewith. Each of the heating portions of the heating resistor is provided with one or a plurality of laser-made holes, and the resistance value of each heating portion of the heating resistor is regulated to a predetermined level on the basis of the number of the laser-made holes.

    摘要： A thick film thermal printing head having a substrate, an insulating glaze layer formed on the substrate, a heating resistor formed into a straight elongated shape, a driver IC for controlling energization of the heating resistor, a plurality of first lead wires for connection between the heating resistor and the driver IC, a common electrode serving as an intermediate power supply point through which electric power is supplied to the heating resistor, and a plurality of second lead wires for connection between the heating resistor and the common electrode, the first and second lead wires are alternately disposed parallel to each other, at least the first lead wires, the second lead wires and the common electrode being formed on the glaze layer. The heating resistor is formed in the vicinity of an end surface of the substrate, and the lead wires, the common electrode and the driver IC and other components are suitably arranged to form a thick film thermal printing head structure having no insulating interlayer and no through holes at the connection between the lead wires and the common electrode, enabling simplification of the manufacture process and a reduction in the manufacture cost. It is also possible to improve the printing performance of a thermal transfer facsimile apparatus or thermal transfer printer as well as to reduce the size thereof by using the thick film thermal printing head of the present invention.

    摘要： A digital signal is provided by correcting image signal distortions contained in an image signal outputted from an elongated direct contact type image sensor in an image reader such as a facsimile device, which image sensor reads patterns on a document in contact with the document. The image signal distortions of the sensor output are so-called shading distortions due to sensitivity distribution of sensor elements or distribution of light from light sources onto the document. Signal distortions are corrected from both a white signal outputted from the sensor when a white document is read and a black signal outputted when a black document is read. The white signal and the black signal are stored and reproduced to generate a reference signal which is obtained by dividing the voltage range across both the signals at a predetermined ratio. The digital signal is obtained by comparing the sensor output with the reference signal. If necessary, a pseudo-black signal may be produced by dividing the voltage of the white signal.
