Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention organizes and stores image data read by an image scanner in a storage unit, and retrieves the data from the storage unit and displays or prints the data as necessary. The present invention relates to an image file device.

2. Description of the Related Art In a conventional image file apparatus, image data of a document read by an image scanner at one time is handled as one page. Image data of one page is used as a processing unit, and compression-coded data is stored in the storage unit for each page.
Further, the data retrieved from the storage unit is decoded page by page and supplied to a display or printer.

Problems to be Solved by the Invention For example, it is assumed that a large image scanner capable of reading documents up to A1 size is provided. There is no waste or inconvenience when the A1 size original is put on this and the image data is processed as one page. However, when a small-sized original is placed on the large scanner, the part outside the original is also scanned, and that part becomes the margin outside the document, and the image data including the margin is processed as one page. Various wastes and absurdities such as wasteful use of data, extra time required for encoding and decoding, and useless blank space when an image is printed.

A general image scanner is devised so that the extra-document margin is not generated in the sub-scanning direction (the reading is completed when the sub-scan reaches the end of the document). However, the length of the main scan of the scanner is constant (this is called the scanning width), and a margin outside the document is inevitably generated when reading a document having a small width.

If two A3 size originals are set side by side in the A1 size scanner in the width direction, the width becomes equal to that of the A1 size and the image can be read without the above waste (4th See figure). In addition, two originals can be read at once, and work efficiency when inputting a large number of originals is good.
However, since the image in which two originals are arranged is processed as one page, the data of the two originals cannot be handled as separate pages. In other words, the image cannot be displayed or printed unless the two images are merged.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to divide image data read and registered at one time by an image scanner into a plurality of pages and individually output them. An object is to provide an image file device.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a mounting table capable of mounting a plurality of sheets and a plurality of originals mounted on the mounting table.
A reading means for reading by operation; and a storage means for storing a plurality of originals read by one operation in the reading means as one physical page and storing a logical page for each one of the plurality of originals. Read means for sequentially reading the document image stored in the storage means in the main scanning direction in units of physical pages, designating means for designating a logical page of the document image stored in the storage means, and main scanning for the reading means. It is provided with an output means for outputting only when the document images sequentially read in the direction are within the range of the logical page designated by the designating means.

According to the present invention, the plurality of read originals are stored in the storage means as one physical page by the above-mentioned configuration, and a logical page is added to each of the plurality of originals and stored.
The document image is sequentially read from the storage means in the main scanning direction in units of physical pages, and the output from the reading means is output to the output means only when it is in the same range as the logical page designated by the designating means, and not in the same range. At times, a mask is applied so that the output means does not output.

Embodiment FIG. 1 shows a schematic configuration of an image filing apparatus according to an embodiment of the present invention. This device is an image scanner 1
And (determined as A1), a coding circuit 2 for compressing and coding the image data from the image scanner 1, a memory 4 for storing the coded image data in an organized manner, and a data for the memory. A memory control circuit 3 for performing write / read access control, a decoding circuit 5 for decoding the data read from the memory 4 to restore the original image data, and a page division circuit corresponding to the above-mentioned divided page output means. 6 and an output unit 10 for outputting the decoded image data
And (display 7, A1 size printer 8, A3 size printer 9, etc.), a main controller 11 that controls the entire apparatus in general, and an operation unit 12 that gives various operation commands to the main controller 11. Is equipped with.

As described above, the image data read at one time by the scanner 1 is internally processed as one page (which is the physical page), is encoded by the encoding circuit 2, and is arranged in the memory 4 via the memory control circuit 3. And stored. Of course, data reading is also performed in page units. In the case of a normal output mode other than the page division mode according to the present invention, one page of encoded data read from the memory 4 is returned to the forward dimension image data by the decoding circuit 5, and the decoding circuit 5
Is passed through the page dividing circuit 6 and supplied to the output unit 10. The image for one page is displayed or printed.

As shown in FIG. 4, two originals of A3 size are set side by side on the image scanner 1 for A1 size and set by the scanner 1 at a time. Then, the document and the combined image of the document are stored in the storage unit 4 as one physical page. At this time, a logical page number for distinguishing the manuscript from the manuscript is given to each by the operation unit 12, and the memory 4
Register in.

When outputting the image of the above document, the corresponding logical page number is designated by the operation unit 12. In response to this, the main controller 11 gives a command to the memory control circuit 3 to take out the data of the combined image with the original from the memory 4, and outputs the output from the decoding circuit 5 to the page division circuit 6. A command to extract only the image data of the document is given. Each part operates according to this command,
Data of some logical pages in one physical page (manuscript)
Is supplied to the output unit 10.

FIG. 2 is a configuration example of the page division circuit 6, and the operation in the page division mode is shown in the timing chart of FIG.

As shown in FIG. 4, when the originals are arranged and the image data read by the image scanner 1 is taken out from the memory 4, the image data shown in FIG.
Z1 is sequentially output in series. The data Z1 shown in this figure corresponds to one main scanning line of the scanner 1.

The image data Z1 from the decoding circuit 5 is supplied to the output unit 10 via the gate 62, and the enable signal from the decoding circuit 5 is supplied.
Y1 is supplied to the output unit 10 via the gate 61, and the clock signal X synchronized with the pixel of the data Z1 is supplied to the output unit 10 as it is.

When the enable signal Y1 is turned on, the clock signal X is input to the counter 64 via the gate 63, and the counter 64 counts it. The counter 64 is preset with the number N1 of pixels of A3 size in the main scanning direction. When the clock signal is counted by N1, the count end signal is output to the control unit 65.

Original data exists in the first half of the image data Y1, and original data exists in the second half. The counter 64 outputs a count end signal when the data of the first half of the image data Y1 has been input.

It is assumed that a command has been issued from the main controller 11 to the control unit 65 to output the image of the document. In this case, the control unit 65 turns on the control signal a until the count end signal is generated after the enable signal Y1 is turned on, and then turns off the control signal a. Then, the first half of the image data Z1 passes through the gate 62, and the second half is masked by the "white" data. This becomes the image data Z2 to the output unit 10. When the enable signal Y2 is output to the A1 size printer 9, the enable signal Y2 should be the same as the enable signal Y1.
When outputting to the format printer 8 or the display 7, only the first half is turned on.

It should be noted that only the data of the second half of the original of the image data Y1 can be supplied to the output unit 10 in the same manner as described above.

EFFECTS OF THE INVENTION As described in detail above, a plurality of read originals are stored in the storage means as one physical page, and a logical page is added to each of the plurality of originals and stored. The original image is sequentially read from the storage unit in the main scanning direction in units of physical pages, and the output from the reading unit is output to the output unit only when the range is the same as the logical page designated by the designating unit. Since a plurality of originals are read by the reading operation, the reading and storage time can be shortened, and the output means outputs only when it is the same as the logical page designated by the designating means, and masks when it is not the same. Therefore, it is possible to output a document image of an arbitrary logical page with simple control.
