Title:
THERMAL HEAD DRIVING CIRCUIT
Document Type and Number:
Japanese Patent JPS6376668
Kind Code:
A
Abstract:
PURPOSE:To simplify the wiring pattern of a strobe signal and the structure of a connection means connecting the pattern and an external circuit by permitting a delay circuit to delay the strobe signal of one input by a prescribed time and supplying the signal to each heating body group. CONSTITUTION:The strobe signal SB is given to a 2nd group of ANDs 48-258-45-512 with the delay of one pulse by a delay circuit 50-1. In order to open the ANDs 48-258-48-512, the prescribed places of the heating bodies 41-257-41-512 are conducted through transistors 49-257-49-512. Similarly, heating bodies 41-513-41-768 in a 3rd group are conducted by the output of a delay circuit 50-2, while heating bodies 41-769-41-1024 in a fouth group are conducted by the output of a delay circuit 50-3. Thus a prescribed image can be printed on a recording sheet.
