The operation of the present invention will be described below with reference to the flow chart shown in FIG. First, from the telephone screen in Figure 2, F
When the AX key 27 is operated, the FAX screen of FIG. 3 is displayed,
In this state, as shown in step 1, the handwriting input area 3
Handwriting input to 7 is performed. After the input is completed, if it is determined in step 2 that the save key 29 has been operated,
After writing the data input in step 3 into the page memory 14, in step 4, the handwriting input area 37 is erased so that the next screen can be input, and the process returns to step 1 to input the next screen. Then, step 1 to step 4
The above process is repeated to sequentially store the FAX data to be transmitted in the page memory 14.

On the other hand, when there is no save instruction in step 2 and it is judged in step 5 that the FAX transmission key 36 has been operated, that is, when the input of the FAX data to be transmitted is completed, FIG. The transmission mode setting screen shown in is displayed. In this setting screen, a magnification setting of whether the FAX transmission data input by handwriting is transmitted at the same size or enlarged and transmitted, the edit mode whether the input to the handwriting input area 37 is portrait or landscape, and the FAX number of the destination Settings are made.
The setting of the magnification and the edit mode is selected by the arrow key 28 and set by the setting key 39, and the FAX number is set by the ten key 20. That is, the magnification is set in step 6, the edit mode is set in step 7, and the FAX number is set in step 8. Thereafter, when the transmission start key 40 is operated, the transmission FAX data is created in step 9 and the transmission process is performed in step 10 based on each setting, as described in detail below.

Next, the creation of FAX data in step 9 will be described. The input to the handwriting input area 37 described above can be performed in two ways: vertically using the handwriting input area 37 or horizontally. Figure 6
Shows the page memory 14, and in particular, in this figure, the handwriting input area 37 is used in portrait orientation to store a plurality of pages (6 pages in the figure) of input data. The page memory 14 is a digitizer with L
The number of dots in the handwriting input area of the CD display unit 10 (512
The input data is managed corresponding to (* 240). As described above, when the data is input using the handwriting input area 37 in the portrait orientation, if the magnification is set to the same magnification in step 6 and the edit mode is set to portrait orientation in step 7, the control of the memory control circuit 15 is performed. Thus, the handwritten input data is read from the page memory 14 in the order shown by arrows 1 to 5,
It is sent to the magnification conversion circuit 16. When the magnification is set to the same size, it is sent to the editing circuit 17 as it is, an appropriate blank is added to each page, and stored in the buffer memory 18 via the memory control circuit 19. Similarly, under the control of the memory control circuit 15, the data is read out in the order of arrow 6 to arrow 10, and the same is followed by arrow 255.
Data is read out in the order of arrow 2600 from 6 and sequentially stored in the buffer memory 18. In parallel with this, the control circuit 13 controls the encoding memory 9 and the FAX codec unit 8 to send the FAX transmission data to the PHS control unit 4, and the FAX transmission is performed. As a result, FIG.
As shown in (5), each handwritten input data is arranged in the vertical direction five by five and transmitted.

FIG. 8 shows the page memory 14 when the handwriting input area 37 is used horizontally. In such a case, if the magnification is set to 1: 1 in step 6 and the edit mode is set to landscape in step 7, the handwritten input data is read from the page memory 14 in the order shown by arrows 1 to 3, and the memory control is performed. Buffer memory 1 via circuit 19
8 is stored. Similarly, the arrows 4 to 6 and the arrows 718 to 720 are sequentially read out and encoded in the same manner. The transmission data created in this way is
As shown in FIG. 9, three pieces of handwritten input data are arranged horizontally and transmitted.

Next, the case where the magnification is set to enlarge in step 6 will be described. Figure 10: Handwriting input area 3
7 shows the page memory 14 when 7 is used in portrait orientation, and the memory control circuit 1 is the same as in the case of the same size as described above.
Under the control of 5, the handwritten input data is read out in the order of the arrows. After that, the buffer memory 18 is temporarily stored through the magnification conversion circuit 16 and the editing circuit 17 and is encoded, which will be described with reference to FIG. FIG. 11 schematically shows the processing of handwritten input data when the magnification is enlarged. FIG. 1A shows the page memory 14, and the number of dots is 6 for simplicity. As described above, the pixels are read from the page memory 14 in the order of arrow 1, arrow 2, arrow 3, and arrow 4 under the control of the memory control circuit 15 and sent to the magnification conversion circuit 16. In the magnification conversion circuit 16, each pixel is set to 2
It is sent to the edit circuit 17 repeatedly one by one, and the edit circuit 17 inserts appropriate blank data before and after each page and stores it in the buffer memory 18 as data as shown in FIG. Thereafter, under the control of the control circuit 13, the FAX transmission data is sent to the PHS control unit 4 by the encoding memory 9 and the FAX codec unit 8, and the FAX transmission is performed. At this time, “standard” is set as the transmission condition. Set and sent. On the receiving side, as shown in FIG. 7C, the handwritten input is doubled and output. In this way, as shown in FIG. 12, two pieces of each handwritten input data are arranged vertically and output.

Further, if the magnification is set to enlarge in step 6 and the edit mode is set to landscape in step 7, the handwritten input data is read out in the order shown in FIG. 13, and the same processing as that shown in FIG. 14 is performed. As described above, the handwritten input data are arranged side by side and output.

[0019]

As is apparent from the above description, the present invention, in the information terminal device according to the present invention, transmits handwritten input data to a rectangular input display device of which size is limited, Optimal transmission data is created regardless of whether it is used in portrait orientation or landscape orientation, so that the recording paper of the FAX machine on the receiving side is not wasted. In addition, the input image can be enlarged and transmitted by designating the magnification, and the output that is easy to see can be obtained.
