After the user presses " YES " key on the touch panel 79, determine the document image direction of transfer, shown in Fig. 8 (b), does at this moment display show: transmit from Top-of-file? (S4), transmit from the file bottom? (S5), or by the principal direction transmission? (S6), according to demonstration, the user presses one of them on touch panel 79.Step S5 " transmits from the file bottom ", because the top margin up to file all has the information that will transmit, for the Top-of-file of avoiding receiving is covered by top margin image (date received and time, the page number etc.), fileinfo is lost, so select to transmit from the file bottom.Determined step S4, S5 and S6 shown in Fig. 8 (c), are step S7 after one of them, and display 78 points out input to transmit the dialed digit of destination on display screen.

Shown in Fig. 8 (d), after user's input dial numeral, press shown touch screen 79 initiating keys (S8) of display 78, according to pressing the instruction that host CPU 80 sends behind the initiating key, scanner begins to read file (S9).At this moment, display 78 shows " reading file ", shown in Fig. 8 (e).

The image data storage of reading according to the instruction of view data read-write controller 83 (S10) in image data memory 93.94 pairs of view data that are stored in the image data memory 93 of image identification unit are analyzed, and promptly compare (S11) with the character data that is stored in the dictionary memory 94 '.Judge then whether the file on file table top 14 is last file (S12), if also leave alternative document, then returns step S9.If last file, shown in Fig. 8 (f), display 78 shows " accepting internal memory transmits ".At step S13, image Rotation Controllers 95 is rotated processing according to set condition and analysis result to view data.

With after the point of destination is connected,, under the control of fax CPU87, begin to transmit (S14) by fax bus 90 through the view data of image Rotation Controllers 95 rotations.Fax CPU87 reads communication control program from Control on Communication ROM 89, and utilizes CODEC88, and MODEM 86 and NCU 84 carry out facsimile service with the point of destination.

In step S3, when being set at when the document image direction of transfer not being set in order, or set " the document image direction of transfer is not set in order " at step S6, then transmit the dialed digit (S16) that input transmits the destination by normal internal memory, scanner 10 beginnings are read file according to the instruction of host CPU 80.

The image data storage of reading according to the instruction of view data read-write controller 83 (S18) in image data memory 93.With after the point of destination is connected, under the control of fax CPU87, begin to transmit (S14) by fax bus 90.Fax CPU87 reads communication control program from Control on Communication ROM89, and utilizes CODEC 88, and MODEM 86 and NCU 84 carry out facsimile service with the point of destination.

In step S14 and S19, after the view data in being stored in image data memory has transmitted, facisimile transmission EO (S20).

Image recognition operation below with reference to the process flow diagram recitation of steps S11 of Fig. 9.

Begin view data is analyzed (S21) in image identification unit 94, the initial pictures direction is set to k=0 (S22).To the explanation that Fig. 4 did, image identification unit 94 beginnings compare 1 district view data of reading and the character data that is stored in the dictionary memory 94 ' earlier, i.e. type matching (S23) as preceding.

Image identification unit 94 begins the numeral and the character of view data in 1 district and the character data that is stored in the dictionary memory 94 ' are compared, i.e. type matching (S24), and judge whether character direction mates (S25).If do not match, then hiragana and the katakana character to view data in 1 district compares (26), judges then whether character direction mates (S27).If do not match, then the kanji character to view data in 1 district compares (28), judges then whether character direction mates (S29).

At first the reason that the numeral and the character of the view data in 1 district compared is because the page number and the character majority in 1 district are used as top margin and footer.

Even unmatched situation occurs at step S29, as the preceding explanation of being done in Fig. 4, then image identification unit 94 beginnings are carried out type relatively (S30) to 2 districts earlier.

View data in 39 pairs 2 districts of image identification unit is carried out the comparison (S31) of numeral and character, and judges whether character direction mates (S32).If do not match, then hiragana and the katakana character to view data in 2 districts compares (33), judges then whether character direction mates (S34).If do not match, then the kanji character to view data in 2 districts compares (35), judges then whether character direction mates (S36).

Even unmatched situation occurs at step S36, view data is half-twist (S37) left, and k value "+1 " (38).This k value is corresponding to 90 ° of rotations in image recognition operation, and k=0 represents without spin, and on behalf of 90 ° of rotations, k=2, k=1 represent 180 ° of rotations, k=2 to represent 270 ° of rotations.

Here, judge whether view data has rotated four times (k=4) (S39), if less than four times, then from step S23 re-treatment, if four times, then judge and can not carry out image recognition (S40).

If at step S25, S29, S32 satisfies coupling among one of S34 and S36, and then character direction detects normally, and image recognition finishes, and recognition image direction (S41) continuously.

Flow process narration image direction identifying operation below with reference to Figure 10.

At first, judge that document size is A3, B4 still is horizontal A4 paper (S42).If file is A3, B4 or horizontal A4 paper are then judged and rotated several 90 ° in image recognitions.

If k=0, representative is (S43) without spin, and parameter l adds " 1 " and it is classified as 1 class (S44 and S45).If k=1,90 ° (S46) have been rotated in representative, and parameter m adds " 1 " and it is classified as 2 classes (S47 and S48).If k=2,180 ° (S49) have been rotated in representative, and parameter n adds " 1 " and it is classified as 1 ' class (S50 and S51).If k=3,270 ° (S52) have been rotated in representative, and parameter o adds " 1 " and it is classified as 2 ' class (S53 and S54).

If the file that is placed on the file table top 14 is opposite with the standard state of 1 type, then be defined as 1 ' type.Same method if the file that is placed on the file table top 14 is opposite with the standard state of 2 types, then is defined as 2 ' type.

If file is an A4 paper (S55) longitudinally, then judges and in image recognition, rotated several 90 °.

If k=0, representative is (S56) without spin, and parameter 1 adds " 1 " and it is classified as 3 classes (S57 and S58).If k=1,90 ° (S59) have been rotated in representative, and parameter m adds " 1 " and it is classified as 4 classes (S60 and S61).If k=2,180 ° (S62) have been rotated in representative, and parameter n adds " 1 " and it is classified as 3 ' class (S63 and S64).If k=3,270 ° (S65) have been rotated in representative, and parameter o adds " 1 " and it is classified as 4 ' class (S66 and S67).

If the file that is placed on the file table top 14 is opposite with the standard state of 3 types, then be defined as 3 ' type.Same method if the file that is placed on the file table top 14 is opposite with the standard state of 4 types, then is defined as 4 ' type.

Below, with reference to the flow process parameter statement compare operation of Figure 11.

At step S70, begin parameter l, m, n and o compare, no matter and document size is A3, B4, still horizontal A4 paper (S71).

If document size is A3, B4, or horizontal A4 paper, then comparative parameter 1, m, which maximum of n and o.

When parameter l is maximum (S72), then judge the standard state (S73) that a plurality of 1 classes are arranged.When parameter m is maximum (S74), then judge the standard state (S75) that a plurality of 2 classes are arranged.When parameter n is maximum (S76), judge then a plurality of 1 ' class states arranged that (1 class standard state Rotate 180 °) (S77).When parameter o is maximum (S78), judge then a plurality of 2 ' class states arranged that (2 class standard state Rotate 180s °) (S79).

If file is vertical A4 paper (S80), comparative parameter l then, m, which maximum of n and o.

When parameter l is maximum (S81), then judge the standard state (S82) that a plurality of 3 classes are arranged.When parameter m is maximum (S83), then judge the standard state (S84) that a plurality of 4 classes are arranged.When parameter n is maximum (S85), judge then a plurality of 3 ' class states arranged that (3 class standard state Rotate 180s °) (S86).When parameter o is maximum (S87), judge then a plurality of 4 ' class states arranged that (4 class standard state Rotate 180s °) (S88).
