In the same figure, "10:00 AM meeting" data is selected and highlighted by the user's up / down cursor key operation on the parent device side, and is corrected to "3:00 PM meeting" data (see FIG. 16B). When the synchronized communication processing is executed again, as shown in FIG. 16 (c), the uncorrected "call to 9:00 AM head office" data is displayed on the display screens of the master unit and the slave unit as normal data. Is displayed on the second line of the display column, and the “10:00 AM meeting” data before being corrected on the parent device side is displayed on the third line of the display column together with a double line display indicating before correction as data before correction. The fourth line in the display column together with the display of "parent" indicating that the "3:00 PM meeting" data modified on the parent device side has been modified by the parent device as modified data of the parent device. It is displayed.

Here, as shown in FIG. 16 (c), after the parent device-modified data "3:00 PM meeting" is selected by the user's operation of the up / down cursor keys and highlighted, the synchronization of the input device 32 is performed. When the cancel key is input, as shown in FIG. 16 (d), the data after modification of the master unit "3:00 PM meeting" and the double-line display indicating before modification are deleted, and the display screen is modified. Return to the previous state (see FIG. 16A).

Further, in the above-mentioned master / slave unit synchronized communication processing, when data is corrected in each of the master unit and the slave unit, the normal data, the pre-correction data, the data after the master unit correction, and the slave unit are corrected. The state in which the data after device correction is displayed and the state in which the data after correction of the child device are displayed as the latest data by the above-described child device data latest display process,
As shown in FIG.

First, as shown in FIG. 17A, the parent device (personal computer 2) and the child device (electronic notebook 3)
In each of the display devices, the same data is displayed by the synchronized communication process, the date data indicating the current date is displayed on the first line, and the schedule data is displayed on the second line and below. Have been. Here, as the schedule data, “9:00 AM”
"Call the head office" data and "10:00 AM meeting" data are displayed on the third line. In the figure, "10:00 AM meeting" data is selected and highlighted by the user's up / down cursor key operation on the parent device side, corrected to "3:00 PM meeting" data, and further, the child device side The “10:00 AM meeting” data is selected and highlighted by operating the up and down cursor keys, and after being corrected to the “2:30 PM meeting” data (see FIG. 17B), the synchronization communication process is executed again. And FIG.
As shown in (c), on the display screens of the parent device and the child device, the uncorrected “call to 9:00 AM head office” data is displayed as it is as normal data on the second line of the display column, and the child device side 2:30 PM meeting modified at
The data is displayed on the third line of the display column together with a “child” display indicating that the data has been corrected by the slave as data after the correction of the slave and a double line display indicating before the correction. 1:00 PM meeting "is displayed on the fourth line of the display column together with the display of" parent "indicating that the data has been corrected by the master as the master corrected data.

Here, as shown in FIG. 17 (c), after the slave unit correction data "2:30 PM meeting" is selected by the user's operation of the up and down cursor keys and highlighted, the input device 23 or the input device When the slave unit data key of the device 32 is input, as shown in FIG. 17D, the double-line display indicating before the correction displayed together with the slave unit corrected data is deleted, and the slave unit corrected data is displayed. Is displayed as the latest data, and the data after modification of the master unit is displayed with a double line indicating before modification (see FIG. 17D).

As described above, according to the communication system 1 of the present embodiment, the display data is selected and highlighted by the correction processing, the selected display data is stored as the pre-correction data, and the parent data is stored. The display data after the correction in the device or the child device is newly registered as the corrected data in the parent device or the child device. Also, the synchronization information of the slave unit data is checked by the master / slave unit synchronization communication process, and if there is correction data, the slave unit corrected data is transmitted to the master unit. Check the synchronization information of the master device, and if there is any corrected data, send the corrected data to the slave device to the slave device, and display the status of the data stored in the master device or the slave device by the master / slave device data display processing. Different display data is displayed on both display screens based on the display data.

Therefore, the display data corrected in the master unit, the display data corrected in the slave unit, and the display data before the correction is performed in the master unit or the slave unit include the “after-master” information and the “child”. After-machine correction information or before-correction information is set and stored in the storage device separately from other normal data.
