    摘要: An image reading device comprises: a light source; a first optical element that focuses light emitted from the light source, the emitted light being reflected by a medium in a first detection area; a first detector that outputs first detection information in response to arrival of light in the first detection area; a second optical element that guides to a second detection area a portion of the light emitted from the light source, which portion does not arrive at the reflective medium in the first detection area; a second detector that outputs second detection information responsive to detection of light at the second detection area; and a generator that generates image data of the medium by revising the first detection information on the basis of the second detection information.

    摘要: A thermal printing head for multi-tone reproduction includes a plurality of heating resistors disposed along the scanning line which differ in the magnitude of thermal output upon energization thereof by the same electric current for an identical time period. This effect is achieved by differing the heating area or by differing resistivity of each heating resistors. Selective energization of none, one or more of the heating surfaces enables the reproduction of different tones or colors on the thermo sensitive paper.
