Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a recording device, and particularly to a recording device suitable for recording time-series changes in various input data as waveform changes on recording paper. It is something.

(Prior Art) Conventionally, as a recording device of this type, a dot recording mechanism having a plotter ben, a wire dot head, etc. is used to record on recording paper on which scale lines and scale characters C-1 are printed, as shown in FIG. There are devices that record various types of data. however,
According to this device, when the recording paper expands or contracts due to changes in temperature, humidity, etc., the interval between scale lines changes during recording, resulting in poor recording accuracy. Also, depending on the input data,
The recording paper must be replaced with one on which scale lines and characters are printed according to the input data, and each time, the time axis of the recording paper must correspond to the time of the input data, making the operation difficult. It was complicated.

Therefore, in order to improve the operability, there are some devices in which scale characters and scale lines are also recorded by a dot recording mechanism. However, this method requires a large amount of ink to print not only the waveform for the input data but also the scale characters and lines, which requires frequent refilling of the ink and increases maintenance costs. It has the disadvantage of being expensive. In addition, the characters expand and contract depending on the running speed of the recording paper, making them difficult to read, and the waveform of the input data,
If you select the same ink color for the scale lines and scale characters,
There was an inconvenience that it became difficult to visually recognize the value of input data.

Furthermore, conventionally, recording paper without scale lines or scale characters has been used as a recording device. Graduation lines, scale letters,
There is one that prints and records all input data waveforms. However, in this case, since only one color can be recorded, there is a drawback that it becomes difficult for the user to visually recognize the input data value when the input data waveform overlaps with the scale characters, as described above.

(Problems to be Solved by the Invention) As described above, in consideration of operability, it is desirable to hide the scale lines and scale characters on the recording paper in accordance with the recording of the input data waveform. However, in this case, when the scale characters and the input data waveform overlap, the user cannot easily visually recognize the content of the input data, and it must be said that the system is still unsatisfactory in terms of operability. Furthermore, if scale lines, scale characters, and input data waveforms are written using only the dot recording pattern, a large amount of ink is required, which requires frequent replacement, which poses problems in terms of device availability and maintenance.

The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a recording device that allows a user to easily read input data waveforms and has good operability and maintainability.

[Structure of the invention] (Means for solving the problem) The recording device of the present invention has a first recording mechanism (2, 3, 4i) that records a waveform corresponding to input data on a single carriage 1.
), a scale line, and a second recording mechanism 6 that records scale characters.
A single recording control device 12 is configured to control recording for each recording unit area on the recording paper 5 in accordance with the input data IN1 to IN4 and the scale control data.

(Function) In the recording device of the present invention, the recording control device determines whether the recording unit area is the area to be recorded or the area where the input data is to be recorded based on the incoming input data and scale control data, and determines whether the scale line or scale character is Determine whether the area is for recording.

A first recording mechanism records an area where input data is to be recorded, and a second recording mechanism records an area where scale lines and characters are to be recorded.

If neither of these conditions apply, no recording is performed.

The recording control device sequentially performs this operation for each recording unit area. As a result, the first recording mechanism records the waveform of the input data, and the second recording mechanism records the scale lines and scale characters.

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

The carriage 1 has a solenoid coil 2 as shown in FIG.
The four plotter pens 4i (i=1 to 4) are moved downward by the force of the solenoid coil 2 against the elastic force of the spring 3, and moved upward by the force of the spring 3 by the force of the solenoid coil 2. Third
). Further, the carriage 1 has a thermal head 6 disposed at the bottom of the housing of the carriage 1 so as to face the recording paper 5.
Equipped with.

The recording paper 5 is moved in the longitudinal direction (Y direction) by a platen 8 that is rotationally driven by a first motor 7, and the carriage 1 is attached to a thread 11 and is moved by a second motor 9.
The rotational motion of the recording paper 5 is converted into a linear motion by the pulley 10 and the thread 11.
It is designed to reciprocate in the x direction). That is, the carriage 1 is configured to relatively move on the recording paper 5 in both the x and y directions.

In this embodiment, a plotter pen 41 is provided for recording waveforms of input data, and a thermal head 6 is provided for recording scale lines and scale characters. Recording control for the plotter pen 41 and 4J-maru head 6 and rotational control for the first and second motors 7.9 described above are performed by a recording control device 12 shown in FIG.

The recording control device 12 includes a central processing unit (CPtJ) 13 having a microcomputer configuration. ROM14 for storing programs and fixed data. It is equipped with a working RAM 15.

In the case of this embodiment, a maximum of four pieces of data can be handled as input data that can be recorded on the recording paper 5, corresponding to the plotter pens 41 (1=1 to 4), and four incoming input data can be handled. After IN1 to rN4 are selected by the multiplexer 16, they are further selected by the amplifier circuit 17. The signal is amplified via the analog/digital conversion circuit 18, converted into a digital digital signal, and taken into the recording control device 12.

It is also provided with a keyboard input device 19, and input ports 1 to 2.
Scale control data such as the range (maximum variable range) of each input data IN1 to IN4, units of scale lines, and scale characters to be printed are supplied to the it, IJ m device 12 through the input data input terminal 0.

The control device 12 executes the data processing shown in FIG. 4 based on the incoming input data and scale control data to determine the recording location, and outputs each output port 21, 22, 23, 24 so as to record at the determined location. and driver 25.26.2
7. Thermal head 6, solenoid coil 2 through 28. Motor 7° drives and controls motor 9.

J3, two displays and a display driver 30 are provided so that input data can be displayed as numerical values.

The recording processing procedure by the CPU 13 will be explained. CPU13
For example, after starting the program in step S1 by receiving a print start command from the keyboard input device 19, the program proceeds to the next step S2, and the input data IN is input.
1 to IN4 are captured in chronological order and stored in the RAM 15. Next, in step S3, the scale control data is fetched from the keyboard input device 19, and the input data I
N1 to IN4 and scale control data are calculated for each recording unit area (one line is divided into 1024 unit areas, for example) for one line in the width direction of the recording paper 5.
It is stored in the RAM 15 whether input data, scale lines, or scale characters should be recorded.

After that, in step S4, the unit area N to be processed
is set to an initial value "1", and in the next step S5 it is determined whether or not to record in the recording unit area N. As a result, if a negative result is obtained, the process immediately proceeds to step S9, which will be described later, and if a positive result is obtained, the input data INi
The process proceeds to step S6 in which it is determined based on the contents of the RAM 15 whether to record the scale lines or scale characters.

As a result, in the case of a scale line or a scale character, the CPU 13 proceeds to step S7, drives the motor 9, moves the carriage 1 so that the thermal head 6 is located in the recording unit area, and then moves the thermal head 6. Operate and record. On the other hand, in the case of input data, CPLJ
Step 13 proceeds to step S8 where the carriage 1 is moved so that the plotter pen 41 corresponding to the input data to be recorded is located in the recording unit area, and then the solenoid coil 2 corresponding to the plotter pen 41 is energized. and record it using the plotter pen 41.

As a result, the recording operation for the recording unit area 1ittN is completed, and the CPU 13 sets the next recording unit area N+1 as a new processing target in step S9, and proceeds to step S9.
Proceed to step 10. This step 810 is to judge whether the recording operation <35 to 88) has been completed for all the recording unit areas of the line, and if a negative result is obtained, the process returns to the above-mentioned step S5 and the next recording unit is started. After moving on to the recording operation and obtaining a profile result, in step S11, the motor 7 is operated to advance the recording paper 5 by one line.
Returning to step S2 described above. Thereafter, operations similar to those described above are repeated.

In this way, under the control of the control device 2, the input data IN1 to IN4 captured line by line are recorded by the plotter pen 41, and the scale lines and scale characters are drawn for each line that constitutes them. is recorded by the thermal head 6.

Therefore, according to this embodiment, since it is possible to record scale lines and scale characters, it is possible to omit the need to replace the recording paper for each input data, and to omit secondary operations such as setting the time for recording and paper. Moreover, even if the recording paper expands or contracts, the input data can be recorded with high accuracy with respect to the scale lines.

In addition, since the scale lines and scale characters are recorded by the thermal head 6, and the input data waveform is recorded by the plotter ben 41, the recorded colors etc. are different, making it easy to distinguish between the two and improving visibility. can do. Also,
Since the records are distributed, the failure cycle becomes longer, the ink usage cycle becomes longer, and the maintenance and inspection cycle becomes longer.

Therefore, the thermal head 6 and plotter bench 4
1 recording i control is performed by a single recording control device 12, the control configuration can be simplified, and the carriage 6
can be easily controlled.

In the above embodiment, the thermal head 6 records the scale lines and scale characters, and the plotter ben 41 records the input data waveform, but the recording targets may be assigned in the opposite manner.

Further, as a dot recording mechanism, a wire dot head may be used instead of a plotter, and/or a piezoelectric recording head may be used instead of a thermal head. Furthermore, the number of input data that can be recorded is not limited to the above-mentioned four. Further, it is sufficient that the carriage moves relatively on the recording paper in the XY directions, and the moving directions of the carriage and the recording paper are not limited to those described above.

[Effects of the Invention] As described above, according to the present invention, the first recording mechanism records scale lines, scale characters, etc., and the second recording mechanism records input data waveforms.
The two recording mechanisms are mounted on the same carriage and the recording is controlled by a single recording control device, making it possible to obtain a recording device with a simple configuration and good operability and visibility.
