Thus it is possible to transfer a large quantity of data at a high speed and in a simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a data transfer method between data processing devices such as electronic notebooks.

<Conventional technology> Conventionally, when transferring data between data processing devices such as electronic notebooks, all data stored in the data processing device on the sending side is transferred to the data processing device on the receiving side at once. Alternatively, only the data displayed on the data processing device on the sending side is transferred to the data processing device on the receiving side.

In the latter data transfer method, as shown in FIG. 4, first, the "" key of the data processing device on the sending side is pressed to display the first data of the data stored in the memory on the display device. If the displayed data is to be transferred, the "function" key and the "option" key are used to put the sending side into transmission mode and the receiving side into reception mode. Then, the display on the transmitting side changes to "transmitting" and the display on the receiving side changes to "receiving", and the displayed data is transferred from the transmitting side to the receiving side. When the data transfer is completed, both the transmitting and receiving sides enter the display state of the transmitted data. Next, if you want to transfer other data, press the ``'' key until that data appears, then press the ``Function'' and ``Options'' keys as above. Transfer that data.

Thereafter, similar operations are repeated to transfer the necessary data.

<Problems to be Solved by the Invention> By the way, in the conventional data transfer method described above, in the method of transferring data all at once, it is difficult to transfer only the necessary data out of the data stored in one data processing device to the other data processing device. If you want to transfer the data, you need to transfer the stored data all at once and then delete unnecessary data on the receiving side. Further, in the method shown in FIG. 4, only necessary data can be selectively transferred, but the same operation must be repeated each time data is transferred. As described above, both methods have the problem that the operations are complicated and inconvenient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data transfer method that allows selective transfer of only necessary data with simple operations.

Means for Solving the Problems> In order to achieve the above object, the present invention provides a data transfer method for reading data stored in a storage means of a data processing device and transferring it to another data processing device, In the data transfer mode, the data stored in the storage means is displayed on the data display means for each data, and when the data transfer key is pressed, the data displayed on the display means is displayed on the data processing device of the above function. After the transfer, the next data is displayed on the display means, while when the data update key is pressed, the data displayed on the display means is not transferred to the data processing device of the above function and the next data is displayed on the display means. The feature is that it is displayed.

First, the data processing device on the sending side is set to data transfer/transmission mode, and the first data of the data stored in the storage device is displayed on the display device, while the data processing device on the receiving side is set to data transfer/reception mode. mode. Then, on the sending side, if the displayed data is to be transferred, the data transfer key is pressed, and if not to be transferred, the data update key is pressed.

When the data transfer key is pressed, the display data is transferred to the receiving side, and then the next data is displayed on the display device of the sending side. On the other hand, when the data update key is pressed, the display data is not transferred to the receiving side, and the next data is displayed on the display device on the sending side.

Below, by operating the data transfer key and data update key,
Selectively transfer the data you need. In this way, once the data transfer mode is set, necessary data can be selectively transferred by simply pressing the data transfer key and the data update key.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

Fig. 5 is a block diagram when two data processing apparatuses (A, B) are connected by a communication cable C to realize an embodiment of the data transfer method of the present invention. Each of the data processing devices A and B includes a display device 1, a display control device 2, and a display control device C.
It is composed of a PU 3, a ROM 4.4° 4, an IIAM 5.5, and a keyboard 6.

The data transfer operation in the data processing apparatus will be explained based on the functional explanatory diagram of FIG. 2 and the flowchart of FIG. 3.

FIG. 3(a) is a flowchart for setting the transmission mode or reception mode in the select transfer mode, which is a mode for selectively transferring data. This setting is made by pressing the "Function" key on the keyboard 6 and the "
This is done using the ``option'' and ``s'' keys.

In step A1 of FIG. 3(a), the operator of data processing device A (hereinafter referred to as set A) determines whether data processing device B (hereinafter referred to as set B) is in the receiving mode,
If it is the reception mode, the select transfer transmission mode is set in step A4. Then, in step A5, "select transfer transmission mode" is displayed on the display device 1. On the other hand, if the other party is not in the receiving mode, select transfer receiving mode is set in step A2. Then step A
3, "select transfer reception mode" is displayed on the display device 1.

Figure 2 shows that set A is set to transmit mode and set B is set to transmit mode.
Fig. 3(b) and (c) are respectively functional explanatory diagrams when set to the reception mode.
3 is a flowchart showing the operation of set B.

In step Bl of FIG. 3(b), the CPU 3 on the sending side
'' key is pressed, and when the ``'' key is pressed, the process advances to step B2 to read out the first data from the RAM 5 and display the data on the display device 1 for a certain period of time. Thereafter, the process proceeds to step B3, where "Transfer Y/N", which is a message for inquiring whether or not to transfer data, is displayed on the last line of the display. The operator looks at this display and presses the rYJ key to transfer, or presses the rNJ key to not transfer. When the rYJ key is pressed,
The CPU 3 displays "transferring" on the last line of the display in step B8, and then transmits the display data in step Bg. When the transmission is completed, the process proceeds to step BIO, and the "transfer route" is displayed on the last line of the display for a certain period of time. Next step B
Proceed to step B7, determine whether the display data is the final data, and if it is not the final data, proceed to step B7,
After displaying the next data for a certain period of time, the process returns to step B3.

On the other hand, when the rNJ key is pressed, the process advances to step B6.
It is determined whether the display data is the final data, and if it is not the final data, the process proceeds to step B7, and after displaying the next data for a certain period of time, the process returns to step B3. If the display data is the final data in step B6, step Bi
Proceed to step t, send the transfer completion code, and then proceed to step B.
At step 12, a message "All data selection completed" indicating that selective transfer of all data has been completed is displayed for a certain period of time.

After that, "Name?" is displayed, the mode returns to normal mode, and the transmission mode is canceled.

On the other hand, the CPU 3 on the receiving side performs step C in FIG. 3(c).
Determine whether there is data transfer from the sending side using I.
, if there is data transfer, the process proceeds to step C2, where it is determined whether the received data is a transfer end code. If the received data is not a transfer end code, the process proceeds to step C3 and displays "receiving select transfer", data is received in step C4, and the received data is displayed for a certain period of time in step C5. Thereafter, the "select transfer reception mode" is displayed in step C6, and the process returns to step CI. If the received data is a transfer end code in step C2 above, the process advances to step C7, where the message ``All data selection completed'' is displayed.Then, ``Name?'' is displayed. is displayed, returns to normal mode, and cancels reception mode.

In this way, once you set the select transfer call mode,
After pressing the `` key to display the first data, you can selectively transfer data just by operating the rYJ and rNJ keys, and after transferring data with the rYJ key, the next data is automatically displayed. This allows large amounts of data to be transferred quickly with simple operations.

<Effects of the Invention> As is clear from the above, the data transfer method of the present invention displays the data stored in the storage means on the data display means for each data in the data transfer mode, and when the data transfer key is pressed. When the data displayed on the display means is transferred to another data processing device, the next data is displayed on the display means, and when the data update key is pressed, the data displayed on the display means is transferred to another data processing device. Since the next data is displayed on the display means without being transferred to the data processing device having the above function, a large amount of data can be quickly and selectively transferred with a simple operation.
