<p>PURPOSE:To shorten printing time with a constitution emphasizing compactness and economy as a heatsensitive recorder by providing plural heating resistor rows and composing the recorder so that image information may be distributed and recorded by raster or pixel. CONSTITUTION:A given image information is halved, for instance, by raster and added to a thermal head 3a and 3b, and at the same time, it is so controlled that printing may be performed per raster alternately at a prearranged timing. As a result, it is possible to perform printing of other raster on the other ther mal head while one thermal head is cooling off. Because of the constitution using two thermal heads, the time required for one heating element row to record can be reduced approx. half that for the conventional recorder, if it is so controlled that the first heating element row may exclusively record pixels to be recorded when said row has selected a power line Pl1 and the second heating element row pixels to be recorded when this row has selected a power line Pl2 respectively.</p> |
