PURPOSE:To obtain a multiple-pens recorder excellent in indentification by combining a bar-graph indicator with the multiple colors with a multiple-pens system recording plural signals and indicating the same signal as the multiple- pens system on each bar-graph indicator. CONSTITUTION:An indication unit 5 having the plural bar-graph indicators is provided in combination in the multiple-pens recorder which records plural analog measured signals with the different colors respectively using plural pens P1-P3 on recording paper 2. The same number of these plural bar-graph indicators as the pens P1-P3 are provided to indicate the same measured signals with the same colors as the pens P1-P3 respectively. Hereby, the measured signals can be easily identified even when the feed speed of the recording paper 2 is slow. Further, even in case the pens P1-P3 are arranged by shifting and the recording is performed with a time lag, the measured signals can be identified with a real time.
