<p>PURPOSE:To reduce the recording time for one line's share, by counting the number of black picture element data among recording data and controlling the number of recording electrodes printing at one time with the number of black picture element data. CONSTITUTION:A recording data DATA is stored in shift registers S1-Sn in synchronizing with a transfer clock CLK. The said data is latched to shift registers LS1-LSn and latch circuits L1-Ln with a strobe pulse STB to preset shift registers A1-An to zero. The recorded data BDTA is outputted in synchronizing with a shift clock SCLK and only a black picture element data 1 is counted at a counter C via a logical circuit AND. The shift clock SCLK is stopped at the count end pulse OVER, a prescribed recording voltage pulse DP is applied to recording electrode drive circuits D1-Dn, and only the data set to 1 in the shift registers A1-An is printed as one block.</p> |
