→ Upper / lower limit value limiter 5 → Storage device 6 at the route of storage device 6
Further, it is stored in the storage device 4 in the route of, that is, the route of the storage device 6 → the selection device 11 → the storage device 4. As a result, the CRT display device 9 displays KB
The input data is switched to the PC recognition data. on the other hand,
When the read signal B becomes "H", the screen display switching signal output device 10 switches the character color switching signal from "yellow" to "white". As a result, the PC recognition data on the CRT display device 9 is displayed in "white". The display state in "white" corresponds to the operation and processing of steps 106 and 107 of the flowchart of FIG. 2, and corresponds to the section of the time chart of FIG.

FIG. 4 shows an example of a display screen corresponding to the present embodiment. KB input data and PC recognition data are switched and displayed in one display area Z. At this time, the character color is "white" as described above. → It can be switched in the order of “blue” → “yellow”. Correspondingly, the display area Z is "dark gray" → "dark gray" →
The color is switched to "blue", and only the frame line indicating the display area is displayed in "blue".

Thus, according to this embodiment, the data is displayed by using the single display area, and the recognition data is switched to the input data by the temporary input command and the input data is switched to the recognition data by the main input command. The
Further, the display color of the character can be switched in distinction from the state of waiting for data input by touching the screen.
