Multi pen recorder

摘要

PURPOSE:To provide a multi-pen recorder in which power supply circuit section can be downsized by alleviating increase of load current in each servo system upon concurrent variation of analog input signals to a plurality of systems thereby reducing the capacity of power supply. CONSTITUTION:The multi-pen recorder comprising an operational processing section 3 for taking in analog input signals from a plurality of systems through A/D converters, and D/A converters 4 for delivering data processed at the operational processing section 3 to servo systems for moving a recording pen depending on the magnitude of analog input signal is further provided with a delay means 6 for mutually differentiating the data input timing to the D/A converters 4 within the conversion period of the A/D converter 2.
