    摘要: An image copying system is disclosed which has a thermal head energized at a strobe current supply time rate corresponding to a current head temperature according to a preset strobe current supply time rate control characteristics. In copying operation at a standard speed, a read sensor 211 reads an image by performing N main scans in one sub scan. A signal processor 221 validates the image signal thus read once every N scans according to a selection signal from a mode control circuit 401. A record circuit 311 having a thermal head performs one main scan every sub scan. During a copying operation at a speed N times the standard speed, the sub scan speed is made N times and the read sensor 211 reads the image by performing one main scan every sub scan and the signal processor 221 makes the read image signal always valid by the selection signal. The record device 311 performs one main scan every sub scan. A single A/D converter is used for A/D converting head temperature as well as other output signal.

    摘要: A data communication system by which simultaneous communication of voice and data is possible without disturbing voice communication. During communication between a first telephone and a second telephone through a telephone line, when a data signal from a computer is fed to a data communication system, the data signal is modulated according to a spread spectrum system by a spread spectrum modem, mixed with the voice signal, and transmitted from a line interface to the telephone line. The signal including the spread spectrum modulated data signal and the voice signal is received in the second telephone. The voice mixed with spread spectrum modulated data signal is heard at the second telephone with only slight noise. Thus, talking can continue undisturbed, because energy of the data signal is spread to a wider band.
