<p>PURPOSE:To provide a driving unit which can be divisibly driven by dividing voltage setting means for applying voltages to respective leads into the prescribed groups by the prescribed number and driving them. CONSTITUTION:A phase detector 11 detects the ends of transfers of record signals A, B, C to an editing circuit 10, thereby detecting a recording phase. A record controller 12 starts with the output CAR1 of the detector 11, counts clock pulses CP3, forms a recording timing CAR2, and generates block selection signals BE1-BE3 via the CAR2. The controller 12 detects the temperature of the recording head in a recording circuit 13 as an optimum recording condition. Accordingly, the end of the recording operation is detected by a mode detector 11 by the end of the transfer through the circuit 10 of the recording signals A, B, C to a recording circuit 13, and is performed by divisibly driving the blocks in the prescribed group of the prescribed picture elements from the recording circuit 13 by the controller 12.</p> |
