Abstract

PURPOSE:To obtain easy-to-read recording data by providing a recording control part which varies intervals of lateral scale lines or the length of a longitudinal scale line according to a signal from a means for detecting the extent of variation of analog data and prints the scale lines together with the analog data. CONSTITUTION:A recording control part 11 records the analog data from an A/D converter 10 on recording paper through a recording driving part 17 and when the output of an adding circuit 13 is received, scale data is read out of a scale data storage part 16 and recorded together with the analog data. Then, the frequency of output from the circuit 13 becomes higher and higher as the extent of variation of the analog data becomes larger and larger, and the frequency of reading of scale data by the control part 11 from the storage part 16 also increases, so that scale lines printed on the recording paper become narrower. When the extent of variation of the analog data decreases to the contrary, the sum value of the circuit 13 hardly exceeds an upper limit value, the frequency of output to the control part 11 decreases and lateral scale lines are printed roughly. Thus, easy-to-read recording data is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a recorder capable of recording analog data and printing scales on recording paper.

[Technical background of the invention and its problems]

Conventional recorders use printed recording paper, so
It is necessary to prepare a piece of paper with the desired scale,
It was annoying. In addition, when printing digital data, the scale may interfere with reading the data.For this reason, a recorder that uses blank recording paper and can print the scale while recording analog data has been considered. ing. At this time, we do not simply add scales at regular intervals;
The problem is how to attach suitable scales to analog data to make it easier to read.

[Purpose of the invention]

The present invention has been made to solve this problem, and aims to provide a recorder that can provide a scale according to changes in analog data.

[Summary of the invention]

The present invention detects the degree of change in analog data, and if the degree of change is large, shortens the interval between horizontal scale lines of the stored scale or prints a longer vertical scale line, or vice versa. If the degree of change is small, the interval between the horizontal scale lines may be increased or the length of the vertical scale line may be shortened, so that the scale can be changed in accordance with the change in the analog value.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

10 is A that converts analog data into digital data
/D converter. The output of this converter 10 is supplied to the recording control section 11 and the difference detection circuit 121C.

This difference detection circuit 12 is a San! Since the difference between successive data is detected for each ring, this detection signal is supplied to the adder circuit 1s/C. This adder circuit 13 adds the detection signals from the difference detection circuit 12, and when the upper limit value set by the setting section 14 is exceeded, outputs a signal to that effect to the recording control section 1.

Reference numeral 15 denotes a scale condition selection section, in which, as shown in FIG. It is selected and supplied to the scale data storage section 16. The scale data storage section 16 is configured to output the stored scale data in response to a request from the recording control section 11.

The recording control section 11 normally records the analog data from the A/D converter 10 on the recording paper 20 as shown as 25 in FIG. 2 via the recording drive section 17. When receiving the output from the scale r
- The scale data is read out from the data storage section 16 and recorded together with the analog data.

With this configuration, when the degree of change in analog data increases, the number of outputs from the adder circuit 13 increases.
The number of times that the recording control section 11 reads scale data from the scale data storage section 16 also increases, and therefore the intervals between the scale marks printed on the recording paper 20 become narrower. That is, as the degree of change in analog data increases, horizontal scale lines will be printed densely. On the other hand, when the degree of change in analog data becomes smaller, the added value of the adding circuit 13 hardly exceeds the upper limit value, so the number of outputs to the recording control section 14 decreases, and the horizontal scale line becomes more difficult to print. be done.

In addition to the scale printing command based on difference detection, a scale printing command unit may be provided separately for printing scales (26 in FIG. 2) at regular intervals. Furthermore, when the scale is printed densely, the scale becomes easier to read by not adding vertical scale lines.

Next, another embodiment of the present invention will be described with reference to FIGS. 3 and 4.

30 is an A/D converter t'16° that converts input data into digital data; the output of this converter 30 is:
San! The signal is converted by the ring circuit 31 and supplied to the difference detection circuit 32. In this difference detection circuit 32, the following SAN! The difference between the ring data is detected and supplied to the counter 33. This counter 33 counts the difference in fixed time units, and when the count value exceeds the upper limit value from the setting section 34, it outputs a signal to that effect to the scale storage section 35. Further, this counter 33 is reset by a command signal from the scale generation timing command section 36.

Further, the command signal from the scale generation timing command section 36 is also supplied to the scale storage section 35 and the scale-related data storage section 37. Both storage units 35 and 37 receive the command signal and supply data to the recording control unit 38, respectively. Data such as vertical scale lines stored in the scale storage section 35 and units other than scales and scale values stored in the scale-related data storage section 37 are supplied from the #2 meter setting section 39 and the clock 40. .

The recording control unit 38 also sends input data from a signal conditioner 41 that prepares input data to a recording drive unit 42.
The image is recorded on the recording paper 43 via the recording paper 43.

Further, the scale storage section 35 stores the stored vertical scale line data in the recording control section 38 when a certain period of time has elapsed after receiving the command signal from the scale generation timing command section 36.
However, if it receives a signal from the counter 33 before the data supply ends, it will again operate to continuously send out data for a certain period of time. Further, the counter 33 is reset at the same time as outputting a signal to the scale storage section 35 and starts counting again.

With this configuration, as shown in FIG. 4, the vertical scale lines and related data are recorded on the recording paper 43 together with the input data according to the command signal from the scale generation timing 36. At this time, if the degree of change in the input data is large, the difference in values for each sampling period will be large. A signal to be sent to is supplied. Therefore, when the degree of change in input data is large, long vertical scale lines are recorded together with the input data, as shown at 44.45 in FIG.

This configuration makes it easier to read input data in portions that change rapidly.

[Effects of the present invention]

``Since the present invention is configured in this way, it is possible to print appropriate scales corresponding to changes in input data, and it is possible to obtain easy-to-read recorded data.
