DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a reading unit 2 is provided for a transport path of an object to be read, for example, a mail 1. The reading unit 2 optically reads an image on the mail 1.
The read image is supplied to the character detection cutout unit 3.

The character detection cutout unit 3 detects and cuts out a character pattern from the image read by the reading unit 2. The extracted character pattern is supplied to the temporary word recognition unit 4 and the word pattern holding unit 6.

The temporary word recognizing unit 4 detects a word pattern corresponding to an address display up to the capital, prefecture, prefecture, prefecture, county, and city levels based on the contents of the memory 5. Recognize from inside. The recognition result is a word pattern holding unit 6
And supplied to the table selection unit 7.

The memory 5 is a relatively small-capacity storage means, and stores a standard word pattern and an address code corresponding to an address display up to a predetermined level, for example, a metropolitan / prefecture / prefecture / prefecture / county / city level as a dictionary in advance. I remember.

The word pattern holding section 6 holds each word pattern which is not recognized by the temporary word recognition section 4 among the check character patterns of the character detection cutout section 3. The table selecting section 7 constitutes a reading means together with a reading control section 8 and a word data shift register 10 described later, and sequentially stores the standard word patterns and the address codes in the external storage device 9 for each table and from the upper to the lower. To choose. This selection instruction is supplied to the read control unit 8.

The read control unit 8 sequentially reads out the standard word pattern and the address code according to the selection instruction of the table selection unit 7 from the external storage device 9. The external storage device 9 is a large-capacity storage device such as a hard disk device or an optical disk device, and is a ward, a town, a village, a character, a chome, an address, a number, and the like lower than the city, prefecture, prefecture, prefecture, county, and city levels. A standard word pattern and an address code corresponding to an address display such as a name are hierarchically stored as a table for each level and in association with an address code of an address display located at a higher position. This storage format is shown in FIG.

The standard word pattern and the address code sequentially read by the read control unit 8 are shifted and held in the word data shift register 10 in a serial state continuous with an end signal (END) as shown in FIG. You. Then, of the standard word pattern and the address code shifted and output from the word data shift register 10, the standard word pattern is supplied to the matching unit 11, and the address code is supplied to the address code register 12.

Each time a standard word pattern is supplied from the word data shift register 10, the collating unit 11 collates the standard word pattern and each word pattern in the word pattern holding unit 6 collectively. At some point, a latch enable signal is output to the address code register 12.

The address code register 12 responds to the latch enable signal of the collating unit 11 to read the address code from the word data shift register 10, that is, the address code attached to the matched standard word pattern, as a read result and the table selecting unit. 7 is output as the selection data.

FIG. 3 shows a specific configuration of the word pattern holding circuit 6 and the matching unit 11. The matching unit 11 includes a plurality of comparison circuits 11a, 11b,... 11n into which a common standard word pattern is input collectively. As shown in FIG. 3, the word pattern holding unit 6 includes a plurality of word pattern holding circuits 6a, 6b,.
n.

Next, the operation of the above configuration will be described. The image of the mail 1 is optically read, and the character pattern of the destination address in the read image is detected and cut out. Then, based on the contents of the memory 5, a word pattern corresponding to the address display up to the capital, prefecture, prefecture, prefecture, county, and city levels is recognized from the above-mentioned closed character pattern. The recognition result is supplied to the word pattern holding unit 6 and the table selecting unit 7.
Each word pattern that has not been recognized as an address display at the metropolitan / prefecture / prefecture / prefecture / county / city levels is held in the word pattern holding unit 6.

If the destination address on the mail 1 is, for example, “Toshiba Yanagimachi Factory No. 70, Yanagicho, Sachi-ku, Kawasaki-shi, Kanagawa”,
The word patterns "Kanagawa" and "Kawasaki" are recognized first. The other word patterns existing in “70 Toshiba Yanagimachi Factory” are stored in the word pattern storage unit 6.

As for the word pattern included in "70 Yanagimachi Factory in Yukicho, Toshiba Yanagimachi Factory", for example, in the case of "Yanagimachi", "Kinumachi", "Yanagimachi", "Yanagidacho", "Kinutacho"
There are 4 candidates.

When a word pattern corresponding to the address display up to the metropolitan / prefecture / prefecture / prefecture / county / city levels is recognized, a ward name table corresponding to the address display at the immediately lower level is selected based on the recognition. Then, the standard word pattern and the address code of the ward name table are sequentially read from the external storage device 9. The standard word patterns in the ward name table include “Yuki Ward” and “Tsurumi Ward” (FIG. 2).

When the standard word pattern and the address code in the ward name table are read out in this way, they are collectively collated with each word pattern in the word pattern holding unit 6.
If there is a match in this collation, the address code attached to the matching standard word pattern (if the matching standard word pattern is “Saikoku”, the address code is “1000”) is output as a read result.

At the same time, the output address code becomes the next table selection data. This time, the town name table immediately below the ward name is selected, and the standard word pattern and the address code of the town name table are sequentially displayed. Is read. "Yanagimachi" as a standard word pattern for the town name table
"Asahicho" and others (Fig. 2).

When the standard word pattern and the address code of the town name table are read out in this way, they are collectively collated with each word pattern in the word pattern holding unit 6.
If there is a match in this collation, the address code attached to the matching standard word pattern (if the matching standard word pattern is "Yanagimachi", the address code is "1100") is output as a read result.

At the same time, the output address code becomes the next table selection data. This time, the address / large name table immediately below the town name is selected, and the address / large name table is selected.
The standard word pattern and the address code of the large name table are sequentially read. "No. 60""No.70""Toshiba Yanagimachi Plant"
And so on (FIG. 2).

When the standard word pattern and the address code in the address / large name table are read out in this manner, they are collectively collated with each word pattern in the word pattern holding unit 6. If there is a match in this comparison, an address code attached to the matching standard word pattern (if the matching standard word pattern is “70” or “Toshiba Yanagimachi Factory”, the address code is “1106”) is output as a read result. .

As described above, the image on the postal matter 1 is read, the characters of the destination address are checked, and the checked character pattern is converted into a standard word which is sequentially selected from the upper level to the lower level of the address display. Patterns are collectively collated for each selection and the address code attached to the matching standard word pattern is used as a read result, so that the address on the mail 1 can be read quickly and accurately. Even in the case of wide area sorting processing of mails to be processed, the processing can be executed quickly. The present invention is not limited to the above embodiment, and various modifications can be made without changing the gist.

[0036]

As described above, according to the present invention, characters are detected by reading an image on an object to be read, and the detected characters are sequentially selected from the upper level to the lower level of the address display. All the standard words are checked at once for each selection, and the address code attached to the matching standard word is used as the reading result, so that the address on the object to be read can be read quickly and accurately. For example, it is possible to provide an address reading device capable of performing a wide area sorting process of mails quickly.
