Abstract: PURPOSE:To make it possible to extend the range of radiation and provide a sufficient degree of heating, by installing a reflecting plate comprising a first parabolic locus cross section and a second parabolic locus cross section, which are focused on a heating element. CONSTITUTION:The radiation heat from a heating element 1 reflected on a first parabolic locus cross section 2 advances directly in the same direction as indicated by A. The radiation heat from the heating element 1 radiated on a second parabolic locus cross section 3 advances directly in the same direction with an inclination of an angle theta to the radiation heat A as indicated by A. Therefore, all the radiation heat discharged from the heating element 1 and reflected on a reflecting plate 4 advances directly in either A or B direction without irregular reflection. It is, therefore, possible to extend the range of radiation, providing a satisfactory extent of heating.

Abstract: PURPOSE:To simplify the read scanning of lots of originals by using a self- running means so as to carry an original of a read object through an original carrying path. CONSTITUTION:An operating sheet feed guide 15 is removed from a housing upper part and a roll 16 is set to the side of an original read face in contact with a drive roller 1 and a driven roller 4 and the entire reader is placed while an original read face is directed upward. In this case, the direction of revolution of a motor 3 is in a direction (c) opposite to the direction at manual scanning. In this state, when a sheet original 17 is loaded from a side notch of a sheet feed guide 15, the original 17 is carried in the direction of the arrow (e) through the driven roller 4 and drive roller 1. In the case of reading, since the direction of rotation of the roller 1 is reverse to that at self-running, after a data of one line is once stored in a buffer by one line, the CPU 31 reads the data reversely. Moreover, an encoder disk 5 is driven to obtain a read pulse.

Abstract: PURPOSE: To discriminate the edge side part of an original for detecting a background pattern at the time of image input. CONSTITUTION: A characteristic background pattern provided with the image data of a specified frequency is attached to the background member of a document, and a background is detected in an image frequency detection circuit.

The edge side part detection mechanism controls various erasing mechanisms for erasing the detected pattern as well and prevents the pattern from appearing inside the images.  A sensor for generating a strong wavy pattern at the time of being used for a specified background pattern may be manufactured also.
