PURPOSE:To prevent the lowering of density of a recording image at the beginning of recording by mounting a pulse power control means for altering power in a predetermined number of electric pulses when a non-recording period detection means detects that a prodetermined number of recording data are not inputted continuously. CONSTITUTION:When a recording start signal is inputted, the presence of recording data is judged in a step S1 on the basis of the logic 'H' or 'L' of a data block signal transmitting the recording data of one pixel at every one clock pulse and, when the presence of the data is judged, predetermined control numbers (n), (m) are set. Next, the presence of recording data in the data block signal is investigated and, when there is no recording data, the value of (m) is reduced by 1 and, when m=0 is judged, recording procedure is returned to the Step 1. When the presence of data is judged, m=m is set and a pulse width is set to (x). This pulse width (x) is wider than the pulse width (y) used at the time of usual recording. Next, the recording due to the pulse width (x) is performed and 1 is subtracted from (n). This recording due to the pulse width (x) is performed until a recording end signal is detected or n=0 is obtained and, when recording over n-times is judged to be finished, the recording due to the usual pulse width (y) is performed. |
