PURPOSE:To arrange recording data on the time base, by shifting positions of recording pens from one another so that adjacent pens do not collide and delaying one input signal for the purpose of allowing recording data to coincide with each other on the time base. CONSTITUTION:The signal of a channel CH 1 is shifted on a recording paper by the interval between pen points P1 and P2 and is recorded as if it were generated a time T later than the signal of a CH 2, and the recording paper is moved in the direction of an arrow. For the purpose of eliminating the time difference, input signals of the CH 1 and CH 3 having pen points P1 and P3 in later positions out of input signals driving a pen motor are delayed in a delay circuit by the time T corresponding to the interval between pen points. Thus, input signals of the CH 1 and the CH 3 are applied at a time (t)=t1, when data of the CH 2 recorded at a time (t)=t0 reaches positions of pen points P1 and P3, the time T after as shown in figure, and recording waveforms of the CH 1- the CH 3 are arranged on the same time base. As the result, time bases of large- amplitude recording data are arranged relatively inexpensively. |
