<p><P>PROBLEM TO BE SOLVED: To provide a thermal printing device which can shorten warming-up time, reduce heat or load stress to be brought to bear on a thermal recording sheet, save power consumption, and accelerate the conveying speed of the sheet by solving a conventional problem of a heat roller mounted in an image erasure part of the heat-sensitive recording sheet. <P>SOLUTION: A heater 91 positioned at a right angle with the conveyance direction of the thermal recording sheet 60 and in a direction parallel with the sheet 60 regarded as a longitudinal direction, is installed inside a cylindrical housing 92. Further, a slit-shape opening 93 is opened in an opposite part to the sheet 60 of the housing 92, and also a blower 94 for blowing air to the housing 92 is installed. Under this constitution, an image is erased by blowing a hot blast to the sheet 60 in a non-contact fashion, while the sheet 60 is conveyed between conveying rollers 12 an 23. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
