Description

Detailed Description of the Invention (1) Technical Field of the Invention The present invention relates to a recorder that records a plurality of analog data.

(2) Prior Art A thermal recorder is known as this type of recorder. This thermal recorder has a thermal head arranged across the width of thermal recording paper, and each heating element of this head selectively generates heat according to an input signal, as shown in Fig. 1. It records multiple analog data.

Further, as shown in FIG. 1, different identification marks are recorded near each recording line. This identification mark is attached to identify which recording line corresponds to which analog data.

(3) Problems with the prior art However, in parts A to C surrounded by dotted lines in FIG. There is a drawback that it is not possible to determine at a glance which recording line E, B, and C indicate.

(4) Purpose of the Invention The present invention has been made to address the above-mentioned drawbacks, and even if the recording lines at the positions marked with identification markings intersect, it is impossible to determine which recording line the identification markings indicate. The purpose of this project is to provide a recorder that allows you to determine at a glance whether there is a fish or not.

(5) Structure of the Invention The present invention is configured to record a mark indicating which recording line the identification mark indicates.

(6) Embodiment of the Invention An embodiment of the invention will be described below with reference to FIGS. 2 and 3.

FIG. 2 is a circuit diagram of one embodiment, and 10 is an AD converter that converts a plurality of input analog data into digital signals. 11 is a recording control section connected to the output side of this AD converter 10. 12 is an identification mark generator connected between this recording control section 11 and the AD converter 10. 13 is this identification mark generator 12
is a mark generator connected in parallel with .
Reference numeral 14 denotes a recording timing generator that supplies read signals to the mark generator 13 and the identification mark generator 12. This generation part 14
generates a signal synchronized with a plurality of analog data input to the AD converter 10, and is connected to both the generators 12 and 13 via the gate 15.
It is connected to the. This gate 15 is the timer 1
6, it is opened at regular intervals or arbitrarily by an external operation signal. Reference numeral 17 denotes a drive unit that causes a heating element of, for example, a thermal head (not shown) connected to the recording control unit 11 to generate heat.

The drive section 17 receives signals corresponding to a plurality of analog data, identification markings, and marks from the recording control section 11, drives the thermal head, and records the respective data on thermal paper (not shown). Here, as shown in FIG. 3, different alphanumeric characters A to F are used for each analog data. Then, each identification mark is recorded in the vicinity of each analog data at regular intervals at different times.

Further, the mark is recorded based on an analog data signal corresponding to each identification mark at approximately the same time as when each identification mark is recorded. here,
The mark uses a triangular shape and is recorded thinner than the recording line so that the recording line will not be erased even if it overlaps with the recording line of each analog data. This recording is accomplished by making the signal from mark generator 13 apply less electricity to the corresponding heating element of the thermal head than other signals.
Note that this can also be achieved by making the coloring density coarser than that of the recording line.

By recording the identification mark and mark together with the analog data in this way, even if the identification mark is attached at a position where the analog data recording line intersects, the mark will make it possible to identify the analog data recording line indicated by the identification mark. Can be identified at a glance. In addition, by recording the marks thinly, it is possible to maintain sufficient visibility of the recorded lines.

Although the description has been made using a triangle as the mark, it goes without saying that other marks such as an X may also be used. Furthermore, although the description has been made in such a manner that the mark is recorded thinly, for example, only the mark may be recorded in a different color from the other recordings. It is also possible to record marks so as not to overlap recording lines to be marked.

Further, although the identification symbol has been explained using alphanumeric characters, it is of course possible to use other characters such as Arabic characters.

Furthermore, the circuit diagram shown in FIG. 2 shows one embodiment of the present invention, and it goes without saying that various configurations can be considered.

(7) Effects of the Invention In this way, the present invention not only records identification marks corresponding to analog data, but also marks the recording lines corresponding to the identification marks, making it easier to read the records. can be done accurately and quickly.

Claims (1)

[Claims] 1. Record different identification markings for each analog data to be recorded at an arbitrary timing near each of a plurality of recording lines recorded according to different analog data, and record which recording line each identification marking indicates. A mark that is thinner than each recording line and has a certain shape that indicates the identification mark is recorded at almost the same timing as the recording timing of the identification mark, and a part of the mark is recorded over each recording line. Features a recorder.
