PURPOSE:To observe an input signal right after recording, by recording the input signal by a thermal recorder and at the same time displaying said signal by a display. CONSTITUTION:An input signal for which sampling is performed at a recording control part 11 becomes a pattern signal and is entered into a head driver 12, and the driver 12 drives a thermal head 1 and the signal is recorded on heat- sensitive recording paper. The record pattern signal is entered into a shift resister 13 and is held, and the content of this shift resister 13 is read out by a display part 14 and is displayed on a display matrix of a display 4. |
