Abstract

PURPOSE:To display the correlation between a printed value and the corresponding parts clearly, when an input signal value or its operated value is printed by a printer, by printing a mark at the position corresponding to the input signal value on recording paper. CONSTITUTION:In order to record a mark 26, its digital value is imparted to a printer 23 through an interface 24. At this time, a signal is imparted to a driver 27 through an output port 13. The mark 26 is recorded on recording paper 18 based on the output from the driver 27. The mark 26 is attached to recording curves A-N. The value of each input signal at the time when the mark 26 is attached is printed as a digital value 25. CH1-CHn mean channels. In this way, the corelation between the printed value and the part related to this value can be immediately understood at a glance. Erroneous reading of the recording curves and other faults can be prevented in advance.

Description

[Detailed description of the invention] This invention relates to a pen recorder.

As is well known, a pen recorder drives a pen in response to an input signal (analog signal) and thereby records N+2 on recording paper that is transferred. Therefore, the content recorded on the recording paper becomes the input signal waveform with respect to time. However, input G after or during recording? When it is necessary to read the signal waveform, the 14 scale of the recording paper is used as a scale, or another scale is used, but since the recording paper is moving during recording, it is difficult to read it. Furthermore, when using another scale, if the relative positional relationship of that scale with respect to the recording paper deviates, it may cause erroneous reading.

An object of the present invention is to easily and reliably read input signal waveforms recorded on Fi recording paper.

This invention digitally prints an input signal (+h) or a function 3'?4 value obtained by arbitrarily processing the input signal value at an arbitrary time of the input signal waveform, and also reads it on a recording paper. The present invention is characterized in that a mark indicating the input signal waveform portion is recorded.

Embodiments of the invention will be described with reference to the drawings. The figure does not show an example in which the present invention is applied to a multi-pen recorder. 1α～1r

Reference numeral 21 denotes a processing setting section, which is composed of a keyboard, and the transfer speed of the recording paper 18, printing items of the printer controlled by the printer, etc. are set. The setting information is sent to the central processing unit 5 via the input boat 10. recording paper 18 y
To determine the feed rate, the central processing unit 5 divides the clock pulse from the clock oscillator 14 according to the result of the calculation 3f corresponding to the setting self-rise, and sends the +;a pulse to the output port 12.
Send it to Dreitsuk 22. Pulses from driver 22 are sent to step motor 19. The step motor 19 rotates at a speed ε corresponding to the frequency of this pulse.

23 is a printer, to which the calculation results from the medium heat processing device 5 are sent via an interface 24; The content printed by the printer 23 is a digital value of each person's number 11 at an arbitrary time in a simple example. Examples of this include the approximate fraction, f/N fraction, and other calculated a-values at any given time of the input signal. These 4 are medium heat treatment equipment 5
The processing is performed according to the program in the memory 7 when the processing is set by the processing content setting unit 21K. At this time, a mark is also placed on the recording paper at the location corresponding to E0 at that time. An example of this is shown in FIG. 2, where each input signal x1 to

Record.

In order to record this mark 26, when the digital value is input to the printer 23 via the interface 24, a signal to that effect is given to the driver 27 via the output port 16. As a result, the output from the driver 27 drives the marker 28 facing the recording paper 18, and #r! A mark 26 as shown in FIG. 2 is recorded. In addition, instead of this recording, the position servo system 16α~ is recorded via the DA converter 9a~9°.
164, it is enough to move the pen slightly horizontally by 8 Sh (you may also force No. 1. At this time, the mark 26
are attached to the recording curves A to N as shown in FIG.

FIG. 3 shows an example of printing by the printer 23 as described above, in which the value of each input signal (or the calculated value obtained from a set of three predetermined values) at the time when the mark 26 is placed is a digital value. Printed as Jl. "
"CH1" to "rcHnJ" represent each channel, and a digital value is printed on the right side of the display.

When printing is performed by the printer 26 in an arbitrary period of 7 April, the beginning is set as "N01", and the following is rN.
Printing is very good as OkJ. The setting of this cycle T is set by the processing content setting section 21.The setting is sent to the central processing unit 4 and stored in the memory 2 in the same way as the fixed content.
At 4rT, the digital value 1η of the input signal at that time is sent to the printer 23, and a timing signal for printing is given to the output port 13 or a certain digital value (+?+) to the DA converter.
