Abstract: A measurement device (10) includes a first processor (12a) that performs first pipeline processing on a first input signal according to a first sample timing, a second processor (12b) that performs second pipeline processing on a second input signal according to a second sample timing with a sampling period longer than the first sample timing, an adjustment unit that adjusts an output timing of the first input signal on which the first pipeline processing was performed to match an output timing of the second input signal on which the second pipeline processing was performed, and a creation unit (17) that sequentially creates a waveform of the first input signal on which the first pipeline processing was performed and for which the output timing was adjusted by the adjustment unit, and a waveform of the second input signal on which the second pipeline processing was performed.

Abstract: A recorder using a line thermal head is provided with a digital delay circuit for driving heating elements a plurality of times on the basis of one piece of recording data and a thermal history circuit for controlling the driving of the heating elements on the basis of accumulated heat temperature data of the heating elements themselves stored in advance in a memory. This arrangement makes it possible to reduce stepped recording attributable to high speed feeding of recording paper, and to prevent the lowering of printing quality caused by the continuous driving of the heating elements.
