Filed: 1989-09-25
Abstract: PURPOSE:To depict a waveform with a uniform line by dividing the frequency of pulses of a pulse motor on a high-resolution side between two orthogonal directions and inputting the frequency-divided pulses to an ink jet head. CONSTITUTION:When there is no X-axial motion and dots succeed, a control circuit 14 outputs a positive rotation pulse P+ and the ink jet head 9 operates. Then when only a driving pulse Pc is outputted by the circuit 14, no ink is jetted from the head 9. Further, when only the pulse Pc is outputted from the circuit 14, the head 9 jets ink to form dots. Therefore, when there is no X-axial motion, alternate dots are generated and dots are prevented from blurring.
