Next, the operation of the embodiment of the present invention will be described in detail with reference to the flow chart shown in FIG. First, in step S1, a designated screen is set from a plurality of FAX reception data stored in the page memory 9. That is, F
In the AX received image display mode, the first screen is set first, but by operating the cursor key 25,
You can set the screen you want to display, other than the current setting screen. In step S2, it is searched in line units whether or not there is valid image data in the image set in step S1.

That is, in FIG. 7, 44 is a schematic representation of the received FAX data stored in the page memory 9, and 45 is valid data. In step S2, each line L0, L1, L from the beginning of the page memory 9
It is sequentially searched whether or not effective pixel data exists in 2 ,. In step S3, if the existence of the pixel valid data 45 is searched for in the line L7 as shown in FIG. 7, in step S4, the block dividing means 33, based on the reduction ratio set by the reduction ratio setting means 32, As shown in FIG. 7, the block 46 is set, the presence / absence of valid pixel data in the block set in step S5 is searched, and if the presence of valid pixel data is confirmed in step S6, the block 46 is determined in step S7. Is displayed on the LCD display unit 11 with a digitizer.

At this time, for example, when the effective pixel data 47 exists at the position shown in FIG. 8, the effective pixel data 47 is searched in the line Li in step S3, and the effective pixel data of the block 48 is first searched in step S6. However, since the effective pixel data 47 does not exist in this block 48, the process proceeds to step S9. In step S9, it is determined whether or not the block search in one direction is completed, that is, F
It is determined whether the block search is completed up to the right end of the AX received data. Therefore, in the case of FIG. 8, the process returns to step S5, the block 49 is set again, the block search is performed, and the detection on the effective pixel data 49 causes the display on the LCD display unit with the digitizer to be performed in step S7.

Then, in step S8, it is determined whether or not there is an instruction to display the next screen, that is, whether or not to display the blocks before and after the block currently displayed. For example, in FIG. 4, when the image shown in the display area 38 is displayed, the operation of displaying the next image (in FIG. 2B, the >> key 27 is pressed) causes steps S9, S5, and After the processing of S6, the display area 39 is displayed in step S7. When the operation of the >> key 27 is detected in step S8 while the display area 39 is displayed, step S8 is performed.
Since it is determined in 9 that the block search is completed, the process returns to step S2, the same processing as described above is repeated, and the images in the display areas 40, 41, and 42 are sequentially displayed. In this way, by confirming the display of the five screens, the image for one page of the A4 size can be confirmed.

When it is detected in step S10 that the search for all lines has been completed, the process ends. Note that FIG.
It is also possible to search and display in the opposite direction by pressing the << 26 key.

When the end of the screen display process is instructed in step S11, the process ends.
