Abstract

PURPOSE:To prevent the continuity of analog recording from being impaired, without reversing a recording paper during the printing operation, by providing an analog recording mechanism, a printing mechanism and the like to enable smooth assembly with a simple construction. CONSTITUTION:A platen 1, an analog recording mechanism AR, a printing mechanism CP and the like are arranged. Then, a recording paper 2 is fed in a fixed direction with a motor. The magnitude of a measuring signal is recorded analog on the recording paper 2 with pens P1-P3 while the feed speed of the recording paper 2 of the like is printed to record with a pen P0. Here, the pen P0 is displaced in the direction of feeding the recording paper 2 or directions perpendicular to and vertical to the feeding direction according to the printing signal.

This will not impair the continuity of analog recording.

Description

[Detailed Description of the Invention] [Industrial Field of Application J] The present invention relates to a pen recorder, and more specifically, it provides a pen recorder that can record a predetermined print pattern on recording paper as needed. It is something.

[Prior Art] A pen recorder is widely used for analog recording of various measurement signals because it can continuously record the magnitude of a measurement signal.

Incidentally, a pen recorder is generally equipped with an analog recording mechanism having a pen that is displaced in a direction perpendicular to the feeding direction of the recording paper according to the magnitude of the measurement signal and records the magnitude of the measurement signal on the recording paper in an analog manner. The feeding speed of the recording paper is 1 day.

No printing mechanism is provided for recording predetermined printing patterns related to various analog records such as time, alarm information, and time markers.

Such a printing mechanism includes a dot printer mechanism that uses a dot pattern head such as a wire dot head or a thermal head to selectively drive predetermined dot elements according to a print signal to print a predetermined dot matrix pattern. A conceivable plotter mechanism is to displace a pen in a direction perpendicular to the feeding direction of recording paper in response to a print signal, and to move the recording paper in forward and reverse directions to print using analog line segments.

[Problems to be Solved by the Invention] However, incorporating the former dot printer mechanism into a conventional Venn recorder increases cost and is difficult in terms of space. Further, incorporating a plotter mechanism having the latter structure is not preferable because the recording paper is sent back in the opposite direction during printing, which impairs the continuity of analog recording.

The present invention has been made with attention to these points, and its purpose is to have a relatively simple structure that can be easily incorporated, and to prevent the recording paper from being sent back in the opposite direction during printing operations. To provide a pen recorder having a printing mechanism that does not impair the continuity of analog recording.

[Means for Solving the Problems] The present invention achieves the above object by displacing the magnitude of the measurement signal on the recording paper by displacing the recording paper in a direction perpendicular to the feeding direction of the recording paper according to the magnitude of the measurement signal. An analog recording mechanism that has a ben for analog recording, and a mechanism that moves in the recording paper feeding direction, in a direction perpendicular to the recording paper feeding direction, and in a direction perpendicular to the recording paper according to a print signal, and a predetermined printing pattern on the recording paper. The present invention is characterized in that it is provided with a printing mechanism having a recording ben.

[Example] Hereinafter, a detailed explanation will be given using the drawings.

FIG. 1 is a simplified structural explanatory diagram showing one embodiment of the present invention, and shows an example of a three-pen recorder that records the magnitude of measurement signals of three channels in analog form. In Figure 1,
Three bends P are installed at the top of the platen 1 along the feeding direction of the recording paper 2 wound around the cylindrical platen 1.
, ~P3 are arranged in 84 layers, and a printing mechanism CP having a Ben PO for recording a predetermined printing pattern on the recording paper 2 is arranged below these analog recording mechanisms AR. Reference numeral 3 designates a chart cassette in which a portion 3a for storing unrecorded recording paper 2a and a portion 3b for storing recorded recording paper 2b are integrated, and is disposed at the bottom of the printing mechanism CP. . 4 is recorded recording paper 2 sent out from platen 1
This is a holding member that guides the platen 3b to a predetermined storage portion 3b, and is arranged so that its end faces the platen 1 with a predetermined gap maintained therebetween. 5 is a display unit, and each ben P1 to P
3 along the width direction of the recording paper 2.

6 is a case, and 7 is a door.

FIG. 2 is a configuration explanatory diagram showing a specific example of the printing mechanism CP in FIG. 1, and the same parts as in FIG. 1 are given the same reference numerals. In FIG. 2, 8 indicates that the Ben arm 9 is connected to the shaft 10.
The carriage is rotatably attached to the main shaft 11 and the slave shaft 12 via the main shaft 11 and the slave shaft 12. Both ends of the main shaft 11 and the slave shaft 12 are fixed to side plates 13 and 14, respectively, and are kept parallel to each other. A tooth profile 11 is formed at one end of the side plate 13 so as to mesh with a gear 1G attached to the output shaft of the motor 15, and rotates about the main shaft 11 in accordance with the rotation of the motor 15. Reference numeral 18 denotes a drive plate for moving the Ben arm 9 in the vertical direction, and is rotatably attached to a side plate of the main body (not shown). A plunge v21 of a solenoid 20 is connected to the drive plate 18 via a link 19, and rotational driving force is applied thereto. Reference numeral 22 denotes a reeling line for moving the carriage 8, which is wound around a driving pulley 24 which is rotationally driven by a motor 23, and then wound between driven pulleys 25 and 26, and is aligned on the carriage 8.

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

The recording paper 2 is continuously fed in a fixed direction indicated by an arrow A at an arbitrarily set speed, for example, between 5 ml/H and 612,000 III/H by a recording feed motor (not shown). On the recording paper 2, the magnitude of the measurement signal is recorded in analog form by each of the sensors P1 to P, and the feeding speed of the recording paper 2 is recorded by the sensor Po.

Various print records such as time, alarm information, and time markers are performed. In such print recording, Ben Pa is moved in the feeding direction of the recording paper 2 and the recording paper 2 according to the print signal.
The recording paper 2 is displaced in a direction perpendicular to the feeding direction of the recording paper 2 and in a direction perpendicular to the recording paper 2. To displace the pen Po in the feeding direction of the recording paper 2, the motor 16 is rotated to displace the Ben arm 9 in the front-back direction with respect to the platen 1.

To displace the carriage 8 by moving the reeling line 22 by the motor 23 in a direction perpendicular to the feeding direction of the recording paper 2, and to displace the pen Po in a direction perpendicular to the recording paper 2, The solenoid 20 is selectively energized to rotate the drive plate 18 and displace the pen arm 9.

As a result, a predetermined print pattern is recorded on the recording paper 2 while the recording paper 2 is being continuously fed.
A tilt pattern corresponding to the feeding speed of the recording paper 2 is recorded. Here, for example, if 20 characters are printed on one line and the printing speed is 2 characters per second, it will take 10 seconds to print one line. If the limit of the inclination of the recording pattern is 2m+1 for 100m1, then the limit of the feed speed is 2 mra/10s = 720s+n
+ / H, and as mentioned above, from 5 ml 1 l/H to 1
For recorders that can set any feed speed between 2000em/H and 720m from 5m+1m/H.
Printing with an allowable inclination can be performed at a feed rate between +a/H. Note that in this embodiment, the motor 16
, 23 are pulse motors with the same characteristics that can print at a speed of about 5 cm/'S with a resolution of 0.21 ffiI11, for example. For this purpose, each pulse motor 1G
, 23 must be initialized. For such initialization, a mechanical stopper may be provided and a drive pulse is applied for a predetermined period of time to cause the pulse motor to step out before initialization is performed, or a switch may be provided and its contact It may be initialized by a signal. Alternatively, positioning may be performed by directly connecting an encoder to the motor. Further, by energizing these motors 16 and 23 only when printing is performed, it is possible to reduce power consumption and suppress a rise in internal temperature.

In the above embodiment, a recorder using a cylindrical platen was described, but it may be a flatbed recorder or a vertical recorder configured such that the pen is vertically displaced. Good too.

Also, the number of pens is not limited to three, but 2flII and 4 pens.
It may be 111 or more.

Alternatively, a servo motor may be used as the motor for forming the print line groove, and may be combined with a potentiometer to convert the digital print signal into an analog signal and apply it.

[Effects of the Invention] As explained above, according to the present invention, it can be easily incorporated into a relatively simple structure, and recording paper is not sent back in the opposite direction during printing operation, resulting in continuity of analog recording. A pen recorder having a printing mechanism that is not damaged can be realized, and the practical effect is great.
