<p>PURPOSE:To give various functions with instructions of a processor to simplify the constitution by constituting a driving circuit with an output driver, a gate, and a latch and connecting this circuit to the processor of a control circuit by bus connection. CONSTITUTION:Many driving ICs 200 are arranged in a recording head of a high-temperature recorder to constitute a driving circuit 20, and one end of each IC200 is connected to a heating body 10 consisting of a resistance. Recording data input terminals Data, -WR, and A0-A2 are connected commonly to individual ICs 200A. A detector 202 is connected to ICs 200 individually, and they are selected by inputs A3-A7. Each driving IC200 is constituted of the output driver, the gate, and the latch circuit and is connected to the processor of a control circuit 3 by bus connection. Various functions are given to the recorder in accordance with instructions of the processir of the control circuit 3, and the capacity of the recorder is improved to simplify the constitution.</p> |
