PURPOSE:To simplify a constitution and an electric insulation, by a method wherein a digital conversion, a memory function, and a delay function of an input signal for pen difference correction are commonly used. CONSTITUTION:An N-number of input signals are consecutively applied to terminal 1A-1N, the signal of the terminal 1A is applied to a servo-mechanism 2A, and with a pen 3A started, a recording is conducted on a recording paper 4. The other input signals are produced into digital to be stored in their respective memories 22A-22M. After a time delay is produced by means of each memory, they are produced into analogue again to be applied to servo-mechanism 2B-2N, their respective pens 3B-3N record on the recording paper 4. Even if there is a pen difference thereupon, all inputs are recorded with the same time-axis origin in common. |
