RECORDER AND FACSIMILE EQUIPMENT WITH THE SAME

摘要

PURPOSE:To reproduce even an isolated dot when a black ratio is low while preventing heat storage by controlling energy applied to a recording head corresponding to the counted number of black information and energizing times at the time of recording the prescribed amount of pictures. CONSTITUTION:A thermal head 10a is provided with a shift register 130 for inputting and holding the serial recording data by one line and a shift clock 123 from a data processing circuit 117 and outputting the recording data as parallel signals, a latch circuit 131 for latching the data of the shift register 130 by a latch signal 127 and a heat generating element 132 composed of an exothermic resistor by one line. The output signal 126 of a temperature sensor 59 for detecting the temperature of the thermal head 1Oa is inputted to a recording control part 118. Thus, the recording control part 18 changes the pulse width of a strobe signal 129 corresponding to the detected temperature of the thermal head 10a and changes the applying energy to the thermal head 10a corresponding to the characteristics of an ink sheet.
