    摘要: The apparatus of the present invention is provided with a stain preventing element provided between a print drum and a hammer and adapted to shield alternate digits to be printed, said stain preventing element being shiftable in the transverse or advancing direction of print sheet. Said hammer is an intermediate hammer which is set to a predetermined initial position from an unsteady position upon the turning on of the power supply, and simultaneously necessary preparations such as paper feeding and ink application onto the print drum prior to the printing are performed. Also there is provided a stain preventing mechanism for multi-color printing, and the above-mentioned stain preventing member is provided with a means for preventing ink diffusion. Also the paper feed plunger etc. is structured similar to the said hammer thereby rendering the entire apparatus smaller and more compact.

    摘要: A printing head has two or more columns each consisting of a vertical array of dot printing elements. A pulse motor moves the printing head relative to paper, and another pulse motor line feeds the paper upon printing each line. The columns of the head print dots in a superposed manner at high speed under the control of a CPU including memories for storing 7-dot patterns and a control program, respectively.

    摘要: An image reading apparatus includes a plurality of light sources for illuminating an original, a photoelectric conversion device for converting light from the original illuminated by each of the plurality of illuminating means, and a discriminating circuit for discriminating whether or not any image exists on the original, based on image signals output from the photoelectric conversion device at least when the original is illuminated with light from one of the light sources, which possesses spectral characteristics including green. A control circuit controls the apparatus so that, when the discriminating circuit has determined that no image exists on the original, the manner of reading of the image with the light sources other than the light source employed in the discrimination performed by the discriminating circuit is changed from the manner of reading of the image with the light source employed in the discrimination.
