<p>PURPOSE:To improve the print quality by varying a delay time of a print timing in response to a motor exciting change time interval when a recording carrier motor enters intermittent operation so as to improve fluctuation of a picture recording position due to the effect of the motor excitation change time interval by a motor trigger. CONSTITUTION:A motor trigger signal is sent to a current driver 22 to switch an exciting phase of a motor 21 and stepping operation is implemented. Whether or not an intermittent flag is 0 is discriminated and when '0' is judged, the main scanning is proceeded. That is, when picture data are outputted continuously from a decoder 34, a strobe signal fed to a print head 32 and used, to print picture data is immediately outputted. However, it is judged that the intermittent flag is not 0, a scanning delay in response to a scanning delay register content is executed. That is, when the picture data are not continuously outputted from the decoder 34, the start of the main scanning is delayed.</p> |
