Abstract

PROBLEM TO BE SOLVED: To obtain a recorder in which a cascade display can be set easily by a method wherein a printing region in every channel is computed by a control circuit on the basis of a preset recording width and a preset shift width, a printing circuit is controlled and measured data is printed inside the printing region. SOLUTION: In a measuring circuit 1, measured waveforms in a plurality of channels are converted into a digital signal so as to be supplied to a control circuit 2 as a measured signal. In the control circuit 2, the measured signal 100 is stored once in a storage circuit or the like inside the control circuit 2. The control circuit 2 designates a channel which is used to compute a printing region, and is judges whether the designated channel can be printed or not. When it can be printed, a recent printing region is found from a recording width and a shift width on the basis of a previously computed printing region. The control circuit 2 outputs printing data, a printing start signal or the like as a control signal 101, and a printing circuit 3 prints a measured waveform on a sheet of recording paper on the basis of the control signal 101. In this manner, it is possible to obtain a recorder in which the recording width or the like is not required to be set for every channel and in which a a cascade display can be set easily.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recorder for printing measurement data such as waveform data on a recording sheet, and more particularly to a recorder for automatically shifting a printing area at regular intervals and printing the same.

[0002]

2. Description of the Related Art In a conventional recorder, a measured value is recorded by printing waveform data and the like measured in a plurality of channels on a recording sheet.

However, when a plurality of channels have the same range and the measured values are almost the same, the printed waveforms overlap each other. For example, even if the printing color is changed for each channel, the waveform of each channel is changed. Cannot be determined.

Therefore, conventionally, the printing waveform of each channel is separated and displayed by shifting the printing area for each channel at a fixed interval (hereinafter referred to as cascade display).

FIG. 5 is an explanatory view showing such a conventional printing example. “A”, “B”, and “C” in FIG. 5 are print areas of channels 1, 2, and 3, and “D”, “D” in FIG.
"E" and "f" are the print waveforms of channels 1, 2 and 3.

As a result, a cascade display as shown in FIG. 5 allows a plurality of channels to have the same range,
Moreover, even if the measured values are almost the same, the print waveform of each channel is displayed separately.

[0007]

However, in the conventional example, when such a cascade display is performed, a print area must be set for each channel. For example, FIG.
The shift width shown in the middle "g" and "h"
There is a problem that the recording width and the like shown in FIG. 4 must be set for each channel, and if the number of channels is large, the setting operation takes a long time. The problem to be solved is to realize a recorder that can easily set the cascade display.

[0008]

According to the present invention, there is provided a recorder for printing measurement data on a recording sheet, comprising: a measuring circuit for receiving the measurement data of a plurality of channels; A print circuit that prints the measurement data, and a control that calculates a print area of each channel based on a preset recording width and shift width, and controls the print circuit to print the measurement data in the print area. And a circuit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of a recorder according to the present invention.

In FIG. 1, reference numeral 1 denotes a measuring circuit for taking in a plurality of measured values, 2 denotes a control circuit, 3 denotes a printing circuit, 100 denotes a measurement signal, and 101 denotes a control signal.

A measurement signal 100 which is an output of the measurement circuit 1 is connected to a control circuit 2, and a control signal 10 from the control circuit 2
1 is connected to the printed circuit 3.

Here, the operation of the embodiment shown in FIG. 1 will be described. The measurement circuit 1 converts measurement waveforms of a plurality of channels into a digital signal or the like and outputs it as a measurement signal 100 to the control circuit 2. The control circuit 2 temporarily stores the measurement signal 100 in a storage circuit or the like in the control circuit 2.

The control circuit 2 outputs necessary data such as print data and a print start signal to the print circuit 3 as a control signal 101 after performing arithmetic processing and the like necessary for waveform printing. The printing circuit 3 prints a waveform measured based on a control signal 101 from the control circuit 2 on a recording sheet.

Further, the operation of the embodiment shown in FIG.
This will be described with reference to FIGS. FIG. 2 is a table showing each setting example, FIG. 3 is a flowchart for explaining a print area calculation process in the control circuit 2, and FIG. 4 is an explanatory diagram showing a printing example of the embodiment.

In FIG. 2A, channels 1, 2, and
The measurement ranges of 3, 6, 7, 8, 9 and 10 are “2V”, and channels 4 and 5 do not perform printing.
P "state is set respectively.

On the other hand, in FIG. 2B, assuming that the recording width of the entire printing paper is "100", the recording width of each channel is set to "72" and the shift width is set to "5".

When the print area calculation processing shown in FIG. 3 is performed in the control circuit 2 under these setting conditions, first, FIG.
As shown in (a), a channel whose print area is to be calculated is specified.

Then, as shown in FIG. 3B, it is determined whether the designated channel can be printed. For example, since “SKIP” is set for channels 4 and 5, the calculation of the print area is not performed.

If printing is possible, the current print area is calculated based on the print area calculated previously, as shown in FIG.

That is, if the lower limit of the print area is "0" and the upper limit of the print area is "72", the shift width "5" is added to each value, and the lower limit of the print area "5" and the print area are set. Upper limit "7"
7 "is set as the print area of the designated channel this time.

However, when the upper limit of the print area exceeds the recording paper width "100" as shown in FIG. 3D, the lower limit of the print area is set to "0" as shown in FIG. Then, the upper limit of the print area is reset to "72" which is the recording width.

FIG. 4 shows the result of printing each waveform by using the print area calculated according to the flowchart shown in FIG.

That is, the recording paper width "1" shown in "a" in FIG.
In contrast to "00", the waveform "B" of channel 1 is "" in FIG.
As shown in C, printing is performed based on the print area designated by "0" to "72".

The waveform "d" of channel 2 is indicated by "e" in FIG.
“5” to “” shifted by the shift width “F” as shown in
Printing is performed based on the print area designated by 77 ".

Similarly, the waveforms of the channels 3, 6, 7 and 8 are "g", "h", "li" and "nu" in FIG.
"10" to "82", "15" to "8"
7 "," 20 "to" 92 ", and printing based on the print area specified by" 25 "to" 97 ".

However, channels 4 and 5 are "SKIP"
Is designated, no printing is performed, and the shift width between channel 3 and channel 6 is "5".

Further, the waveform of the channel 9 is shown in FIG.
The print area becomes “30” to “102” by the calculation of, and the upper limit exceeds the recording paper width “100”.
It becomes "0" to "72" like the middle "c". Then, similarly to the above, the print area after the channel 10 is calculated.

As a result, by calculating the print area of each channel based on the recording width and the shift width, it is not necessary to set the recording width and the like for each channel, so that the setting of the cascade display becomes easy.

Since the recording paper width varies depending on the type of the printing circuit 3 provided in the recorder, the recording paper width is set to "10".
Although the recording width and the shift width are determined by converting to 0 ", the control circuit 2 determines the recording paper width based on information from the printing circuit 3 and the like, so that the actual length, for example, in" mm "units. It is also possible to set the recording width and shift width with
The recording width and the shift width can be set intuitively.

[0030]

As is apparent from the above description,
According to the present invention, the following effects can be obtained. By calculating the print area of each channel based on the recording width and the shift width, it is not necessary to set the recording width and the like for each channel, so that a recorder that can easily set the cascade display can be realized.
