Abstract

PURPOSE:To position a recording means such as a recording pen automatically at a ruled line behind an adjacent ruled line on the basis of position information on the recording means about ruled lines on recording paper when the recording paper and recording means stop changing in relative position. CONSTITUTION:The recording paper 10 is displaced by a pulse motor 12 in a lateral-axis direction and the recording pen 14 is driven for displacement in a longitudinal-axis direction. Ruled lines 16 are printed previously on the recording paper 10 and the pulse motor 12 is controlled under the command of a CPU18. Outputs of an analyzer, etc., are fetched in an RAM24 through input/output interfaces (I/O). Data on various condition setting are inputted on a keyboard 26. Data and control instructions are transferred among the respective I/Os, RAMs, ROMs, and the CPU through a bus line 30. Further, the recording pen is positioned at the ruled line behind the adjacent ruled line, so recording results are discriminated more easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a recording apparatus, and particularly to the movement i[fh of a recording means such as a recording pen with respect to the ruled line of recording X1.

[Backbone of invention] l ()

Generally, a device that records on recording paper is used as a means for displaying analysis results from an analyzer or output results from various measuring devices. The analysis results recorded on these recording papers are
1- as a variable, and let fl(l1111 be the second physical h-1 variable for this variable. This 4j,
Looking at 3.il+, for example, it is the wavelength or wave number in the spectrum of a spectrophotometer, the retention time in the chromatogram of a gas or liquid chromatograph, and the quality hL number in the 'jl Ifl spectrum of mass spectrometry. It is a chemical shift in the absorption spectrum of a nuclear magnetic resonance apparatus. Furthermore, in older time measurement devices, it is often simply time.

The analytical results recorded on these recording sheets are based on the premise that the horizontal and vertical axes correspond one-to-one.

Based on this premise, the measurer performs qualitative or quantitative analysis of the analytical sample. Therefore, in order to perform accurate analysis, it is necessary to read the amount of displacement on the horizontal axis9.
Ease of use and accuracy of ωU measurement are required. Then,
In order to satisfy these requirements, general recording paper is pre-printed with jl'1' and glands in the direction of the axes.

There are various ways to draw this ruled line, but usually it is
1 scale between cyn, .).

A marker method is also used to further improve accuracy. In this marker method, for example, short markers are recorded at 1 mm intervals, medium markers are recorded at 5 mm intervals, and long markers are recorded at 10 mm intervals.

However, if the lateral displacement 1111 (a of 1) is primarily considered, it is effective to use ruled lines preprinted on the recording paper. When attempting to obtain a spectrum in the wavelength range of 300 nnl-400 ntn (7) using a meter, the position of the recording pen must be aligned with the ruled line before starting the measurement.

Here, if the horizontal axis feed is 2 On In/Crn, the i position of 20 nm intervals, such as 320.340 nm, can be immediately read. Furthermore, matching the position of the recording pen with the ruled line is also necessary when using the marker method. This is because there is no correspondence between the ruled lines and the markers, and the ruled lines cannot be used effectively, and the existence of the ruled lines even becomes a hindrance to reading the horizontal axis.

However, when using this border, please follow the instructions below:
Such a problem arises. That is, every time a measurement is made, the recording pen position lif and 117. The lines have to match, which makes it difficult to operate. In general measurements, the recording pen and the ruled lines do not necessarily match after the -th measurement. In fact, there are many cases where they do not match. Therefore, in the past, in order to effectively utilize the gτ line, it was necessary to align the recording pen and the ruled line each time the dlll was determined, which resulted in poor operability;
There is an A.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a recording device that automatically aligns a recording pen with a ruled line after recording is completed and allows easy identification of recording results.

[Summary of the invention]

The present invention is based on the positional information of the recording means with respect to the recording paper ``2nd IJ'+'' line at the time when the change in the relative position of the recording paper and the recording means stops. This automatically aligns the recording means with the ruled lines.

Here, the relative liquefaction of the recording paper and the recording means (MIM/) refers to the so-called X-Y type, the recording means is fixed, and the recording paper is
The so-called Y-'11' system is sent out 11 times.The position information refers to the position of the recording means with respect to the print lines at a predetermined interval.

An embodiment of the present invention will be described with reference to FIG. Here, e'1, a so-called Y-T type recorder body is used. That is, displacement of the recording paper 10 in the horizontal axis direction is performed by the pulse motor 12, and displacement in the vertical axis direction is performed by driving the recording pen 14 by a recording pen drive mechanism (not shown).

On the recording paper 10, ruled lines 16 are printed in advance at predetermined intervals. The pulse motor 12 is connected to the arithmetic processing unit i'? , 1 (hereinafter referred to as CJ)) 18 (abbreviated as U) 18 is controlled 1ii11 via a pulse motor input/output interface (hereinafter abbreviated as PMI10) 20.

The output t'1 from the divider 7, etc., is transferred to the random access memory (hereinafter abbreviated as A4) 24 via an input/output interface (hereinafter abbreviated as I10) 22. , A: ji, etc. are entered from the keyboard 26.The software described later is pre-recorded in the read-only memory (hereinafter abbreviated as ROM) 2B. I10.11.AM
, l The transfer of data and collateral instructions between the OM, CPU, etc. takes place via the pass line 30.

Next, this embodiment will be explained using the 71 coach yard shown in FIG. The sequence shown in this flowchart is RO
It is memorized in advance by M2B.

Here, to explain using a spectrophotometer as an example, prior to measurement, information such as wavelength travel JIf, range, recording magnification rate, scanning speed, etc. is input from the keyboard 2G, and once) IA
It is stored in M24. Thereafter, when a measurement start command is input, the process branches in the "YES" direction at determination 5o. In process 52, the number of pulses to be output to the pulse motor 12 is updated based on the 1 green report previously stored in the AM 24.

At the I10 output 54, the calculated number of pulses is 1) M
Set to I1020. With this set, Pal, 1

As the process 18, in process 56, the number of output pulses output to the pulse motor 12 is prepared as an integrated period. Then, when the recording of the spectrum is finished and the sludge stops, the decision 50 branches to "NO".

Then, in a decision 58, it is determined whether the number of output pulses arranged and removed in the process 56 is zero. here,
If the number of output pulses is zero, that is, if the pulse motor 2 is not moving at all, no correction is required, and the routine ends with END'.

However, if the number of stored pulses is not zero for J1 stave, it indicates that the pulse motor 12 has moved, so process 6
It reaches 0. Process 11 (60, A 3rd place 100 C (,
Set the low pulse number to ``1self6J・Il'i l O''
Next y from a16! Divide by the number of pulses required to move to the line. The remainder of this division is the number of overshooting pulses of the recording pen 14 from the last ruled line. Therefore, in determination 62, "a
Cc) If the remainder is zero, this means that the position of the ruled line 16 and the recording pen 14 match, and the process proceeds to step 70. In process 70, 51 [¥3'? By resetting the number of stored pulses, this routine ends with "FJND" in preparation for the next measurement. Note that if the remainder is still not zero in the decision 62, in the process 64, from the digit 1 j" of the current recording pen 14 to the next U"

Then, as mentioned above. Finally, process 70 becomes ``END'' and this routine ends.

According to this embodiment, after recording is completed, the ruled lines of the recording paper and the position of the recording pen are automatically aligned, so there is no need to align the ruled lines and the position of the recording pen before the next recording, which improves operability. will improve.

In addition, since the software is used in the implementation process, it is easy to update or add procedures and content.

Next, the I10 output 68 will be explained. This I1
As a pre-stage of the 0 output 68, the ! of determination 62 is performed. If i is zero, the remainder is not zero, and the difference number is output at I10 output 66.
The positions of are consistent. Therefore, a fixed number of pulses is further output to the PMI 102o. This constant number of pulses is the number of ruled line interval pulses itself or an integral multiple of this number of pulses.

According to this embodiment, the following points are effective.

In other words, if the position 1&( of the recording pen at the end of recording is close to the next ruled line, the recording pen can only be moved at the nearest 1st line trench. The result will be difficult to see.Also, if the recording pen and the ruled line match at the end of recording, it will be impossible to distinguish between the previous and succeeding recording results.In such a case, roughly -:l' The distance between the j lines is 4.1, and by sending the recording pen by the distance between the two fat lines, it becomes possible to distinguish between the two results.It is also effective when storing the two recording results separately.

However, it is also effective when using a wavelength professional method using a spectrophotometric IW meter. Wavelength Pro here refers to specifying multiple wavelengths to be measured in advance, and then using the spectrometer to
'The i-th designated wavelength is set, and the photometric values for each wavelength are sequentially recorded. Conventionally, in this Wavelength Pro, the recording pen was driven in the following manner to draw an elongation graph in order to make it easier to read the recorded values. In other words, move the recording pen down at the 2nd digit (4) on the vertical axis, and send the horizontal axis at the caution position. Then, without moving the horizontal axis, move the recording pen in the vertical direction to the photometric value position. Send to t and that(・〆l
'1 at position 'l11. ``!, production amount horizontal'('lt+ is sent. At that horizontal axis position, move the recording pen to 4 or 1q++ zero position (d
I sent it up to the point, and then I sent it horizontally +1)1). This method of drawing a bar graph requires a complicated circuit configuration.

On the other hand, by using the I10 output 68,
Easy to implement. That is, after aligning the recording pen with the other line, the I10 output 68 records υ, for example, -1!1゛^, for the first wavelength. After setting the second wavelength, the I10 output 68 records the ρ, - ruled line interval. By doing this, since the ruled line of the recording paper is used as the line corresponding to the vertical line 11111 of the conventional bar graph, it is possible to easily record the photometric value of the wavelength pro in a second.

Note that here, a kind of wavelength sweep is performed during the displacement from the first wavelength to the second wavelength, but this is not related to the σ1 determination result and is defined as not the scan referred to in judgment 50. It is necessary to keep it. Since the recording pen is repeatedly displaced in the vertical 11111 direction between the first wavelength and the second wavelength, it is desirable to keep the pen up during this period.

In the description of each of the above embodiments, Y is used as the recording method.
-CH5I is described as being of the T type, but it may be of the XT type.

However, the recording means may be of a heat-sensitive type, a discharge breakdown type, or the like, in addition to recording media.

In the above explanation, the digit of the recording pen 14 is 1i! :1" Although it has been explained that the correction is automatically performed immediately after the end of recording, the correction may be made some time after the end of the measurement and before the start of the next recording. However, in 7J, the following points It is advisable to perform correction after recording is completed. In other words,
Performing the correction before the start of recording Li1J means that there is only one time lag, which is not constant in time, after the command to start recording.
The actual recording is configured to begin. therefore,
When trying to record the reaction fJl image by adding a reagent to an analytical sample, the timing of adding the reagent and the timing of starting recording may not be aligned, and the timing of adding the reagent may not match the ruled lines, or the reaction may be delayed. There will also be cases where the initial phenomenon cannot be recorded.

〔Effect of the invention〕

According to the present invention, the lines of the recording paper are automatically marked after recording is completed.
The operability of matching the position of the gland and the recording pen is improved, and since the ruled line is made to match the rear ruled line rather than the adjacent ruled line, identification of the recorded result is also facilitated.
