PURPOSE:To prevent irregular feed of a thermal recording paper by subdividing a single line into a plurality of groups are moving the thermal recording paper by a single step when an image record reaches the terminal point of each group. CONSTITUTION:A control 20 accumulates recording data DR into a buffer memory 21, and the number of black pixels is counted (subdivided into blocks) starting with the head of this accumulated data DR, forming data DR which amounts to a predetermined value and recording data DT consisting of dummy data before and after the data DR. Then this recording data DT is output to a thermal head 12 synchronized to a clock signal CK, and at the same time, a latch signal LT is output to allow the data DT to be latched to the thermal head 12. After this, a strobe signal SB is output to allow the latched data DT to be recorded on thermal recording paper. In addition, a drive pulse PD is applied to a motor drive part 22 each time the predetermined number of data Dr is processed. Consequently, a stepping motor 23 is actuated to move thermal recording paper by one step. |
