Although the end detecting means for resetting the n data is sunken, it is not shown.

The operation of the vt position configured in this way will be explained.

The AB [1G human power signal applied to the input ψ tone 11 to 1n is the performance rJ 1. The signals are sequentially selected by the scanner 2 controlled by the II control circuit 16 and applied to the amplifier 3.

As the amplifier 3, for example, a grammatical gain amplifier is used. This amplifier 3 is based on the circuit Ill 10 circuit 1
6, the gain is set to t11 so that it is linked to the ski t and s2.
It is controlled and amplified so that the output signal becomes, for example, O~2■, regardless of the magnitude of each analog input No. 15. The analog output signal sent out from amplifier 3 is converted to Al1)+J! J4 converts it into a digital signal and stores it in the first memory 7.
is stored in This data is linearized according to the type of input and stored as a signal for display and 1-ging, and is also used as a signal for trend recording, for example, because it corresponds to a width of 250111 in 0.111 steps. It is converted into a numerical value of 0 to 2500 and stored.The analog part consisting of the scanner 2, amplifier 3 and A/D converter 4 is connected to another digital part via a photocoupler. This makes it possible to completely electrically isolate the analog part and the digital part.On the other hand, the i-digital signal applied to the input terminal 5 is also applied to the interface, E-, which is controlled by the control circuit 16.
The signal is stored as a signal for display and logging via the bus 6, and is also sequentially and selectively stored in the first memory 7 as a signal for trend recording corresponding to the recording width.

The recording paper 8 is intermittently fed by a predetermined distance m each time the recording head 11 is scanned, for example, by a paper feeding mechanism 9 that is controlled by the performance control circuit 16.

As the recording head 11, for example, as shown in No. 41*1, a wire dot head mounted as an impact recording element is used. The wire dot head is I'1
4. As shown in FIG. 4, the ink ribbon IIA is fed along the feeding direction of the recording paper 8 and is dyed in multiple colors in the width direction, and the recording paper 8 is moved in a manner corresponding to the number of color bands of the ink ribbon 11A. The dotting mechanism 11 has a plurality of 11 subs arranged along the feeding direction of the ink ribbon 11A and selectively driven to transfer a predetermined color of the ink ribbon 11A. The recording head 11 configured in this way is moved in a direction perpendicular to the feeding direction of the recording paper 8 by a distance of, for example, 0.1 mm from the recording head moving device 41113'r controlled by the arithmetic control circuit 16 to the recording head moving device 41113'r when the recording paper 8 is stopped feeding. / Sj Tsubu was beaten 4-1 by the last two.

is converted into a digital signal and temporarily stored in the second computer 15. Although this device uses a common memory divided into the first memory 7 and the second memory 15, it is also possible to use independent memories.

In the trend mode, the frame control circuit 16 controls the first
All the data corresponding to the input signal stored in the first memory 15 and the data corresponding to the position of the recording head 11 stored in the second memory 15 are read out, and the data stored in the first memory 15 is read out. Data that is significantly different from the data stored in the second memory 15 is detected. Then, the recording head 11 is moved a predetermined small amount along the scanning direction according to the difference. [When the difference becomes zero, the recording head 11
Sends a control signal to perform dot recording of a predetermined color corresponding to the input terminal selected in 1! j, 43, When sending out these control 11 signals, the recording position of each color +6 is added. Such a correction may be applied, for example, to the first
Each output of the recording head 11 records a predetermined color assigned to each input terminal in each input terminal stored in the memory 7! The phase difference signal for the SS number elements is added r-
or subtracted.

Further, when recording, two or more colors may be mixed as necessary. The recording head 11 sequentially performs these operations once in the process of scanning, and the size of each person's body is printed out in 7 sizes in a predetermined color.
It can be recorded in a log-like manner. 1] In the recording mode, the recording head 11 digitally records the magnitude of each human input signal, for example, in a single color. 13. When displaying these trends and logging shades, the display 18 shows the characteristics of each input signal.

In addition, these various 1
7 control actions are performed based on a given 10 grams.

With this configuration, while the recording head 11 moves from one end to the other end in the scanning direction, and also when returning from the other end to one end as necessary, the power applied to the input terminals 11 to 1n is The size of the analog [1] input signal and the digital 48 input signal applied to the input terminal 5 can be recorded analogously on the same recording paper with dot patterns of predetermined colors according to each, and can be digitally displayed on the display. For example, the measurement results before the frame and the
Changes in results can be monitored continuously. Furthermore, if necessary, the magnitude of a particular analog input signal can be continuously displayed digitally.

By the way, like this! For example, when recording a trend of 30 channels of analog input signals in 6 colors, 1 = 5 channels are assigned to each unit.
The reciprocity of continuous recording with 1al-color wires is quite low, but for example, when recording 300 channels of 7-channel input signals with 6-color C trend, 50
Since 311 channels are used, the frequency of consecutive recordings of the same color is considerably n.

(Problems to be Solved by the Invention) However, if 1-lend recording is performed continuously with the same color of Y-I in this way, there is a risk of burning out the solenoid coil, which is not preferable. Note that since digital recording is performed at, for example, O, amrfl steps, there will be no major problem in the flow.

The present invention addresses these points, and its purpose is to realize a multi-point measurement and recording device that can prevent burnout of the solenoid coil when trend recording is performed continuously using a colored wire. It's about doing.

(Step 'f: to solve the problem)' The multi-point measuring and recording device d of the present invention scans a recording head in which a plurality of selectively driven impact recording elements are mounted for each unit step of raster scanning. In a multi-point measuring and recording device configured to dot record the magnitude of an analog signal at multiple points while The present invention is characterized in that a recording element drive control means is provided which detects the presence or absence of an impact recording element and controls the drive of the impact recording element so that darkening dot recording is performed at constant step intervals when the dot recording steps are continuous.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention, and the same parts as in FIG. 3 are given the same reference numerals. In FIG. 1, 23 is a decoder that detects the recording command output from the U RUJ control circuit 16, and when the recording command detection signal is applied to the monomulti 24, the thinning circuit 25
Add to. The multiplier 24 applies a pulse signal having a pulse width necessary to drive the solenoid 28 of the dotting mechanism 11B to the C solenoid drive circuit 27 via the gate 26. The thinning circuit 25
It detects the presence or absence of consecutive dot recording steps of each applied Wty@ analog signal, and when the dot recording steps are continuous, drives the impact recorder G3a so as to perform thinning dot recording at constant step intervals. The recording data to be controlled is thinned out and output to the game l-26.

With this configuration, in the case of J&J in which the dot recording steps using the wire 1111- are continuous, thinning dot recording is performed at constant step intervals.

FIG. 2 is an explanatory diagram of thinning recording in the apparatus of the present invention, in which the number of dot recording steps using the same WV is 31! The figure shows an IA in which dot recording is performed by thinning out to 1/3 when continuing. In the 21ii4, P+''・1)7 indicates the dot recording block position.

The interval is set to 0.1 mm as described above, and the diameter of the recording dots by the width V is set to 0.4 mrn. If the input data string to the same wire for these recording step positions n P + to P7 is rl-1-0-1-1-0-1J, the 1-thinning circuit 25 extracts data for three adjacent dots. While sequentially monitoring, if there are two or more recorded data "1", the subsequent recorded data is thinned out to 'UIOJ', so the queried data string is l-0-0-1-0-
0-IJ, but the recording dots will partially overlap in the raster scan direction, and considering the human reading resolution, recording continuity will not be impaired and the power applied to the solenoid can be reduced. can be lowered.

In the above embodiment, an example is shown in which the recorded data is thinned out to ⅓, but the thinning rate may be increased or decreased as appropriate depending on the thinning ratio or the configuration.

In addition, such thinning processing is performed by the v4 Feng Ruri control circuit.
It is better to do it in a regular manner.

(Effects of the Invention) As explained above, according to the present invention, the multi-point measurement recording Rj function can prevent burnout of the solenoid coil when trend recording is performed continuously with ν on the same color wire. This can be realized and has great practical effects.
