DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 is a block diagram showing an embodiment of a waveform recording apparatus according to the present invention. In the figure, 10 is a pen-shaped position indicator, 11 is a display constituted by an LCD, etc., 12
Is a tablet, and in the apparatus of this embodiment, a position indication is made up of a plurality of drive coils arranged in parallel with each other at equal intervals and a plurality of sense coils arranged orthogonally to the drive coils in parallel with each other at equal intervals. The pointing coordinate of the position pointing device 10 is configured to be detected with high accuracy by electromagnetic coupling with the device 10. Further, 13 is a recording mechanism having a thermal head for recording on thermal recording paper having a plurality of thermal elements, and 14 is a data processing unit for recognizing what kind of data the coordinate data input from the tablet 12 is. , 15 are LCD drivers for driving the display 10, 16
Is a control unit, 17 is a memory, 18 is a buffer, and 19 is A /
It is a D converter.

Consider a case in which the external waveform signal is input and displayed in the apparatus of the above-described embodiment.
First, an external signal is input from each of the channels CH1 to CH4, the variable amplifier 18 once amplifies or attenuates, that is, the range is converted by the range switching signal d, and then the A / D converter 19 converts the digital waveform signal. Convert to. The converted waveform signal is sent to the control unit 16 based on the clock signal c, and the control unit 16 generates display data according to the input waveform signal and sends this data to the display unit 11 via the LCD driver 15. To do. The display 11 displays a waveform based on the input data. Here, in order to obtain a desired display (output) range, when the enlargement / reduction and the recording of the waveform are performed, the pointing operation by the position indicator 10 is performed.

That is, the display area of the display unit 11 is divided into a waveform display area and a display area of commands for instructing enlargement or reduction of the displayed waveform and output to the recorder 13 as described later. When the command display area is designated by the position indicator 10, the designated coordinates are detected by the tablet 12 formed on the back surface of the display 11 and transmitted to the data processing unit 14. Data processing unit 14
Is provided with a table indicating the correspondence between each display area of the display pattern displayed on the display 11 and the coordinate data in advance. When the designated coordinates are input, the designated coordinates are displayed in the command area based on the table. If it is in the command area, the corresponding command data a is sent to the control unit 16. In this case, the control unit 16
The display data is created by enlarging the waveform of the corresponding portion and the like, is displayed on the display unit 11, and is output to the recorder 13. If the designated coordinates are present in the waveform display area, a comment or the like is added to the displayed waveform or the like, so that the character data b to be added is sent to the control unit 16.

FIG. 2 is a diagram showing an example of a display pattern displayed on the display unit 11. The area of this display pattern is divided into the above-mentioned waveform display area 11a and command display area 11b. Here, channel CH1
Display the waveform signal input from the upper part of the waveform display area,
A case where this waveform signal is enlarged in the time axis direction and displayed in the lower part of the waveform display area will be described. First, channel CH
The waveform signal input from 1 is displayed in the first waveform display area indicated by 11c in FIG. Here, in the figure, the area of the "MAGNIFY (enlargement)" command indicated by P8 is designated and input. That is, when the position pointing device 10 points the area P8, a switch (not shown) provided in the position pointing device 10 is operated to send the information of the pointing coordinate to the data processing unit 14. The data processing unit 14 determines the type of the instructed information whether it is a command or a waveform operation based on the transmitted coordinate information, and sends it to the control unit 16. In this case, it is determined that "a command to enlarge the waveform has been issued" and this information is sent to the control unit 16.

When the waveform enlargement command is given, the control unit 16 waits until the coordinate information of the enlargement range of the waveform signal is input. Here, the operator, for example, in the figure, indicates the designated coordinate P.
By sequentially pointing the points indicated by 1 and P2 by the position indicator 10, the coordinate information of the enlarged range is given to the control unit 16. Next, the control unit 16 displays the enlarged waveform signal after performing arithmetic processing on the designated range of the waveform signal so that the designated range becomes full scale. That is, the waveform signal is appropriately arithmetically processed so that the range indicated by the designated coordinates P1 and P2 in the drawing becomes the range indicated by the designated coordinates P3 and P4 in the drawing, and the second signal indicated by 11d in the drawing is obtained.
This waveform signal is displayed in the waveform display area of. When the arithmetic processing is impossible, the range of the X and Y axes is switched to re-input the data.

The above is an example of the enlarged display of the waveform signal, but the reduced display of the waveform signal can be performed by the same instruction operation. In the case of reduced display, "R
After selecting the "EDUCE (reduction)" command, the waveform signal to be displayed is selected, and the full-scale value is input by an appropriate means such as the position indicator 10 or a numeric keypad (not shown). When inputting the above-mentioned full-scale value using the position pointing device 10, if a sub-window is opened after selecting a waveform signal and a ten-key is displayed in this sub-window to input a numerical value, good. The function of inputting this numerical value can be performed by software processing and can be stored in the data processing unit 14 in advance, so that the design and function change thereof can be easily performed. Further, the output of the displayed waveform signal by the recording mechanism 13 is performed by the "OUTPUT STA" in the command display area 11b.
This is performed by inputting the designated coordinates P9 in the area displayed as "RT". In this case, the data processing unit 14
Sends information indicating the data output to the control unit 16.

FIG. 3 is a flow chart showing the operation of the apparatus of the above embodiment, which summarizes the above operation. That is, when the power is first turned on, the control unit 16
Reads the initial screen data from the memory 17 and displays it on the display 11 (step 30). Then, the initial setting information such as time scale, range, and number of channels is stored in the memory 1.
7 is read (step 31) and external data is taken in through the A / D converter 19 (step 32),
Display data is created from the fetched external data and the initial setting information (step 33). Then, the created display data is driven by the LCD driver 15 to display the display 1.
The LCD display process (step 34) for displaying on 1 is performed.

When a certain area of the display pattern displayed on the display unit 11 is designated by the contact of the position indicator 10 in this way, the result of the detection judgment (step 35) of the designated coordinate on the tablet 12 is " Y ”, and the detected coordinate data is sent to the data processing unit 14. The data processing unit 14 recognizes and determines from the above-mentioned table what kind of information the input coordinate data, that is, the input information, is (step 36).

In this case, the input information is the waveform display area 1
When it is recognized as an additional character drawn in 1b, the control unit 16 converts the coordinate data indicating the additional character into display data, stores it in the memory 17, and changes the data to be displayed on the display 11 ( Perform step 37), then step 3
Return to step 2 of external data import processing. Further, when the input information is recognized as a command for instructing processing such as enlargement or reduction of the waveform, the control unit 16 creates display data based on the recognized command, stores it in the memory 17, and displays it. A data change process (step 38) for displaying on the container 11 is performed, and the process returns to step 32.

If the input information is a command for instructing the output to the recording paper or the end among the above commands, it is first judged whether or not the command indicates the end operation (step 3).
9), if it is an end command, it will end as it is,
If it is not the end command, it is determined whether the command is an output operation command (step 40). If it is an output command, the data already stored in the memory 17 and being displayed on the display 11 is read from the memory 17, and the recording mechanism 1
An output process (step 41) for transferring to 3 and printing is performed.

As described above, the digitizer including the position indicator 10 and the tablet 12 is used as the input mechanism of the waveform recording device, and the display area on the display unit integrally formed with the tablet 12 is used as the waveform display area and the plurality of command display areas. In addition to the above, the command display areas are designated by the position indicator 10, and processing such as waveform enlargement and reduction and waveform data printout processing can be performed without button operation. . Further, it becomes possible to add a memo or the like to the display area, and the memo can be recorded on a recording paper.

In this embodiment, a tablet is used as the input mechanism, and the tablet is configured as a tablet with a display function. However, it is not necessary to add notes such as notes, and highly accurate coordinate detection is not required. In some cases, a thermosensitive tablet may be used instead of the tablet, and in such a configuration, a finger can be used as the position indicating means.

[0018]

As described above, according to the present invention, when the display area of the display is divided into a waveform display area and a plurality of command display areas, and the command display area is designated by the position indicator, Since the waveform signal displayed in the waveform display area is processed by, for example, enlargement or reduction and then output to the recorder, the operation button for processing the waveform signal is unnecessary.
