Description

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

[Technical background of the invention and its problems] This type of recorder is capable of recording analog data and digital data related to the recording line, such as the channel number of the recording line, information related to the recording target, or recording conditions. It can automatically record more information than analog recorders.

However, recording digital data, especially information related to the recording target or recording conditions, takes up a large amount of recording space, so recording of analog data must be temporarily stopped, or data must be superimposed on the recording of analog data. It is.

In the former case, the analog data becomes discontinuous, making it difficult to read, and in the latter case, the analog data and digital data overlap, so
This has the disadvantage that it becomes difficult to read both analog and digital data.

[Purpose of the invention]

The present invention solves these drawbacks,
It is an object of the present invention to provide a recorder that can record analog data and digital data simultaneously and in an easy-to-read manner.

[Summary of the invention]

The present invention enables analog data and digital data to be recorded on the same recording paper, and includes:
This is a recorder in which the ratio of analog data and digital data recorded in the vertical direction of the recording paper is variable.
To this end, we have made it possible to change the amplification gain of analog data, and at the same time to change the scale according to the gain, compressing this analog recording and reducing the proportion that it occupies in the vertical direction of the recording paper, and thereby reducing the unrecorded area. It records digital data.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Reference numeral 10 denotes an analog input gain switching section to which a plurality of analog data are supplied. Each analog data from this switching device 10 is converted into a digital signal by a subsequent ADC 11 and supplied to a recording control section 12. A scale switching section 13 and a data list generator 14 are connected to this recording control section 12 . Further, this recording control section 12 controls the recording head 16 via a subsequent driver 15 using a scale line signal from this scale switching section 13, a digital signal from the data list generator 14, and a digital signal from the ADC 11. It has the function of Furthermore, this recording control section 1
2 is connected to the timer 17.

This timer 17 is connected to the data list generator 14, the scale switching section 13, and the analog input gain switching section 10, and determines when to record digital data. That is, the timer 17 supplies a signal for outputting the digital signal to the recording control section 12 to the data list generator 14 at a preset time. At the same time, the analog gain switching section 1
0, the gain to 1/2, and the scale switching section 13.
Supply switching signals to switch the scale signal to 1/2.

Next, the operation of one embodiment configured as described above will be explained with reference to FIG. 2 as well. First, each analog data supplied to the analog input gain switching section 10 is converted into a digital signal by the ADC 11, and then supplied to the recording control section 12. The recording control section 12 supplies the digital signal as well as the scale signal from the scale switching section 13 to the driver 15. And driver 15
The recording head unit 16 is activated to draw recording lines 21, 22, 23, and 24 corresponding to each analog data on the recording paper 20, as shown above the recording paper 20 in FIG. At the same time, scale lines 25 are also drawn.

By the way, when timer 17 reaches the operating point,
An output command signal is supplied to the data list generator 14, and a digital signal is supplied from the data list generator 14 to the recording control section 12. At the same time, a switching signal is also supplied to the analog input gain switching section 10 and scale switching section 13. Then, the analog input gain switching unit 10 switches the gain to 1/2, and the scale switching unit 13 switches the scale signal to 1/2 and supplies the scale signal to the recording control unit 12.

Therefore, analog data and scale signals are 1/
2, and the recording control unit 12 sends the driver 1
5 to the recording head section 16, and is recorded on the bottom left side of the recording paper 10 as shown in FIG.
At the same time, the driver 15 is also
The digital signal supplied to the recording head section 16 via the recording head section 16 is recorded on the lower right side of the recording paper 10. The recording position of this digital data is determined by the recording control unit 1.
2. In addition, this recording control section 12
supplies a count start signal to the timer 17 when the digital signal from the data list generator 14 ends or when the recording of digital data ends. That is, the signals supplied from the timer 17 to the data list generator 14, scale switching section 13, and analog input gain switching section 10 disappear. Therefore, each section returns to its current state and enters the normal analog data recording state as recorded on the upper part of the recording paper 10.

In this way, when recording digital data, the signal on the analog data side is compressed, and the analog data and digital data are stored in parallel on the recording paper 10.
can be recorded simultaneously.

Note that the present invention is not limited to this one embodiment and can be modified in various ways. For example, we explained the case where analog data is compressed to 1/2,
2/3, 1/3, 1/4, etc. may be selected as appropriate, taking into consideration the recording space for digital data and the visibility of analog data. Moreover, as shown by the dotted line in FIG. 1, it is also possible to record digital data by external input instead of the timer 17 in one embodiment. Of course, while the timer 17 records digital data directly related to each recording line at regular intervals, it is also possible to record other information randomly by external input.

〔Effect of the invention〕

In this way, when recording digital data, the present invention can compress the analog data and record it in parallel on the recording paper together with the digital data. This eliminates the possibility of superimposition of data and digital data, making it possible to obtain records that are easy to read.
