[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of the configuration of a document storage device when the first embodiment of the present invention is applied to a facsimile device. As shown in FIG. 1, the document storage device of this embodiment is
A scanning line density instructing unit 1 for instructing a reference scanning line density and other scanning line densities, and a scanning line density instructed by the scanning line density instructing unit 1 are stored in association with respective pages of a document to be stored. The scanning line density storage unit 2, the document registration unit 3 that registers each page in the document storage unit 4 according to the scanning line density stored in the scanning line density storage unit 2, and the control unit 11 that controls and manages the entire recording apparatus. , A RAM 12 for temporarily storing image information and the like, a communication control unit 13 for performing communication control of a facsimile, an operation display unit 1 for displaying a message to a user and giving an instruction to a document storage device 1
4, an image reading unit 16 for sequentially reading a plurality of documents set in an ADF (Automatic Document Feeding) unit 15, a recording unit 17 for forming an image on a recording paper, for converting scanning line density and for encoding facsimile image information Image processing unit 18 for decoding / decoding
It has.

As shown in FIG. 1, the scanning line density designating section 1 comprises a control section 11 and an operation display section 14, and the document registration section 3 comprises a control section 11 (included in the control section 11). ). Further, the control unit 11 includes a CPU and a ROM containing a program, and the operation display unit 14 has a ten-key pad 21 for inputting a telephone number and the like and a one-touch key 22 for selecting a document in the document storage unit 4, as shown in FIG. A scanning line density instruction key 23 for instructing a scanning line density, a start key 24, and a display unit 25 realized by a liquid crystal display or the like are provided.

FIG. 3 is an operation flow chart at the time of document registration in the above embodiment. The operation of the above embodiment will be described below with reference to FIGS. First, the document (original) to be stored is A
The scanning line density is set in the DF unit 15 (S1), and the operator inputs the scanning line density from the scanning line density instructing key 23 or the like constituting the scanning line density instructing unit 1. This is because the scanning line density instructing unit 1 in the control unit 11 that has detected the setting of the document (original) is the display unit 25.
A message requesting scanning line density instruction is displayed on the screen, and in response to this, the user inputs and instructs the scanning line density of the page number and the image of the page corresponding to the page number. At this time, the reference scanning line density is instructed by first operating one of the scanning line density instruction keys 23 indicated as "normal character", "small character", "fine character" (S2), and then the ten key 21 And the scanning line density instruction key 23 are alternately pressed to instruct each page to be read with a scanning line density different from the reference scanning line density and the scanning line density of the page (S3).

The above-mentioned reference scanning line density is desirable for many pages to read an image according to the reference scanning line density because of the components such as the size of characters on the document to be stored and the fineness of the image. When it is judged that
The scanning line density is selected and determined. So for example
If the reference scanning line density for 8 pages in a 10-page document can be designated, the scanning line density for 8 pages can be designated with one touch, and the operation becomes very simple. Note that the reference scanning line density can be set in advance in common with a plurality of documents, for example, "normal character". In that case, the operation is further simplified because it is only the scan line density of the page to be read that is different from the reference scan line density that needs to be specified for each document. In the above, "normal", "small" and "fine" are, for example, 3.85 lines / mm and 7.7 lines / mm, respectively.
Corresponding to scanning line density of mm, 15.4 lines / mm.

The input scanning line density is acquired by the scanning line density instructing unit 1 of the control unit 11 and stored in the management table of the scanning line density storage unit 2 as shown in FIG. 4, for example. Each record in the management table (data corresponding to each row)
Means, for example, the first record (9 / A, 4B, 6F
/ 6), the stored document is associated with the one-touch key “9”, and the reference scanning line density is “normal character”,
The scanning line density on the fourth page is "small letters", and the scanning line density on the sixth page is "fine letters". The fourth record is currently being registered and is at the stage when the scanning line density instruction is completed and is not yet associated with the one-touch key 22. As shown in the figure, the total number of pages is also set in each record. The scanning line density storage unit 2 may be provided in the RAM 12.

Then, a one-touch key associated (assigned) to the document to be stored is designated (S4). This is because the number of the one-touch key 22 that is unused (not assigned) by the control unit 11 is displayed on the display unit.
Displayed in 25, the user who sees this display can use one-touch keys.
It is realized by inputting a desired unused number from among the displayed by pressing the button 22. When the control unit 11 acquires this number, it sets the acquired number in the one-touch key field of the corresponding record in the management table shown in FIG.

Further, when the start key 24 of the operation display unit 14 is instructed to start reading a document (original) (S5),
The control unit 11 reads the corresponding record from the management table shown in FIG. 4 in the scanning line density storage unit 2 and acquires the scanning line density of the first page. Then, when the scanning line density is given to the image reading unit 16 to instruct the reading of the first page, the image reading unit 16 causes the ADF unit 15 to copy the original of the first page.
To the reading position, the image information of each line is sequentially read from the first line of the document at the line density in the sub-scanning direction (document moving direction) corresponding to the instructed scanning line density (S6).
At this time, the linear density in the main scanning direction (original width direction, line direction) corresponds to the maximum linear density corresponding to the number of pixels of a line sensor (not shown) designed for maximum linear density (for example, corresponding to fine characters). Then, the program processing (software processing) by the control unit 11 or the image processing unit 18 converts the scanning line density to the designated scanning line density. That is, for example, if the instructed scanning line density is half of the maximum line density (corresponding to, for example, a small character), the bit string digitized from the analog value output from the line sensor into the black and white binary is discarded every other bit. . The read image information is stored in the RAM 12 (S6), further encoded by the image processing unit 18 and stored in the document storage unit 4. For manuscripts on and after the second page,
Similarly, reading and storage are performed according to the scanning line density read from the management table in the scanning line density storage unit 2.

When the document stored in the document storage unit 4 is to be transmitted by facsimile, the user only needs to operate the ten-key pad 21 to indicate the destination and to specify the document to be sent with the one-touch key. Then, the control unit 11 that has acquired the data gives the communication control unit 13 a destination number to set up a call with the destination, reads the instructed document from the document storage unit 4, and stores the scanning line density storage. Each page is transmitted to the destination facsimile machine according to the scanning line density for each page stored in the unit 2.

When the image data of the document stored in the document storage unit 4 is output on the recording paper, the operation display unit 14
A print key (not instructed) may be used to instruct the print output, and the one-touch key 22 may be used to indicate the document to be output. Then, the control unit 11 that has acquired these instructions reads the instructed document from the document storage unit 4, and instructs the recording unit 17 to print out the read document. At this time, the scanning line density of the image on each page is converted into the scanning line density of the recording unit 17 and output.

FIG. 5 is a block diagram of the essential parts of the document storage device according to the second embodiment of the present invention. In this embodiment, FIG.
In addition to the configuration of the first embodiment as shown in FIG.
It has. The image composition unit 5 includes a control unit 11a and a RAM.
At the time of registration, the image information of each page stored in the RAM 12 is combined with an image pattern corresponding to the scanning line density of each page. Figure 5
The other structure is the same as that of the embodiment of FIG.

FIG. 6 shows an image image synthesized by the image synthesizing section 5 of the embodiment shown in FIG. One or a plurality of black circles shown in the upper right of each page is an image pattern corresponding to the scanning line density. For example, one black circle is "normal character", two black circles are "small characters", and three black circles are " Fine line means scan line density. When the image information of each page is stored in the RAM 12 at the scanning line density for each page set in the scanning line density storage unit 2, the image combining unit 5 stores the image information.
An image pattern corresponding to the scanning line density is developed into a bitmap at a predetermined position. That is, the control unit 11 is provided with a plurality of image patterns corresponding to the types of image patterns in a plurality of areas of the ROM, and at the time of composition, a pattern corresponding to the scanning line density is read out from the corresponding area of the ROM and bit-mapped. .

After combining, the combined image information of each page is stored in the document storage unit 4 as described above.
Therefore, when such a document is transmitted to the destination facsimile machine or the like, the recording paper with black circles as shown in FIG. 6 is output to the destination facsimile machine. Also,
The image composition shown in the second embodiment may be performed at the time of output, for example, at the time of facsimile transmission output. That is, the scanning line density management table in the scanning line density storage unit 2 has
Since the scanning line densities of the respective pages of the respective documents are set as shown in, when the respective pages are read from the document storage section 4 to the RAM 12 for transmission, the image synthesizing section 5a is The scanning line density management table is referred to, the composition is performed as described above, and the composition is transmitted.

According to the above-described embodiment, since the page with the image pattern indicating the scanning line density can be output on the facsimile receiving side in this way, the receiver has a low cause such as when the image quality of the output document is poor. Read at scan line density,
In addition, it is possible to easily determine whether the image quality has deteriorated due to the transmission at the scanning line density or whether the image quality has deteriorated due to other reasons, so that it is possible to determine whether it is possible to retransmit an even better image quality.

FIG. 7 is a block diagram showing the arrangement of a document storage device according to the third embodiment of the present invention. In this embodiment, as shown in FIG. 7, in addition to the first embodiment shown in FIG. 1, a document connecting section 6 is provided. Document connection section 6
Is configured (included) in the control unit 11 and connects a plurality of instructed documents in the document storage unit 4 as one document. FIG. 8 shows an operation flow of the above embodiment. The operation of the third embodiment will be described below with reference to FIGS. 7 and 8.

First, when the document connection mode is selected from the menu or the like displayed on the display unit 25 of FIG. 2 and the first document instruction request of the document to be connected is displayed in response, the user selects the one-touch key 22. To indicate the desired document (S
11). Similarly, the next document to be linked is designated (S12).
If there is a document to be further connected in addition to these, the same operation is repeated, and if there is no other document to be connected (S1
3) Instruct a one-touch key to be assigned to the linked document to be newly registered (S14).

FIG. 9 shows an explanatory diagram in the case where a linked document in which the document of the one-touch key "1" is the first document and the document of the one-touch key "2" is the next document is assigned to the one-touch key "3". . As shown in FIG. 9, the first document is P1
And P2 and the next document consists of P1 to P3, the first two pages of the concatenated document are P of the first document.
1 and P2, and P3 of the document to be concatenated is successively followed by P1, P2, and P3 of the next document (one-touch key "2").

When the document connection unit 6 acquires each instructed one-touch key number, it registers it in the management table of the scanning line density storage unit 2 as shown in FIG. 10 (S15). Documents assigned to one-touch key "3" (linked documents)
10 has no substance in the document storage unit 4, but when the one-touch key "3" is instructed to send the document, the message shown in FIG.
According to the management table shown in, first, the one-touch key "1"
Document is transmitted at the set scanning line density, and the document of the one-touch key "2" is continuously transmitted at the set scanning line density in one communication.

Further, when linking documents, it is possible to specify not only all pages of one stored document but some pages and link them with all pages or some pages of other documents. It is possible. For example, in the above example, when instructing the second page and the third page of the document of the one-touch key "2", for example, "2 * 3 #" is input by the ten keys 21 after the instruction of the one-touch key. If the one-touch key "1" is used for all pages as it is, the management table of the scanning line density storage unit 2 (third record corresponding to the one-touch key "3") is set as shown in FIG. Reference characters A and B in this table indicate the mode of the reference operation line density as in the case of FIG.

In the embodiment of FIG. 10, when the document of the one-touch key "1" is erased and the document of the one-touch key "3" is left as it is, the document for which the erase instruction input from the operation display unit 14 is acquired. The connection unit 6 checks the management table shown in FIG. 10 to see if there is a linked document,
When it is recognized that the one-touch key "3" is linked to the one-touch key "1" as in the illustrated example, the table contents are updated as shown in FIG. The meaning of the record of the one-touch key "3" in FIG. 12 is that the first page and the second page are output (transmitted) at the scan line density of "normal character" respectively, and then the document of the one-touch key "2" is output. That is. The storage addresses of the first page and the second page are stored in the file management table (not shown) as the storage addresses of the first page and the second page of the one-touch key "3", and the storage addresses of the one-touch key "1" until then. The value set as is set. In addition,
Storage addresses of all pages of all stored documents are set in the file management table, and writing and reading are performed by referring to the storage addresses. Thus, in the third embodiment, a new document can be easily stored without consuming the storage capacity of the document storage unit 4.

Although only the scanning line density has been described above as the reading condition, the conditions such as the halftone reading and the enlargement / reduction reading are also the same as the case of the scanning line density and the standard reading condition and the above reading condition. The operation can be simplified by setting specific reading conditions for different pages only.

[0027]

As described above, according to the present invention,
First, when a document having different scan line densities is stored in a document storage device, a reference scan line density of a document to be stored and a page number of a page whose scan line density is different from the reference scan line density are stored. The operation is simple because it is only necessary to indicate the scan line density. Secondly, in facsimile transmission of stored documents, by outputting a document with an image pattern indicating a scanning line density on each page, the user can Since it is possible to easily determine whether the image quality is poor due to the scanning at the low scanning line density and the transmission at the scanning line density, or the image quality is poor for other reasons, it is possible to determine whether it is possible to retransmit the better image quality. Thirdly, a new document can be registered in the document storage device by a simple operation without consuming the storage capacity of the document storage unit, so that the number of documents that can be stored is increased and the document storage is simplified.
