2. Description of the Related Art In recent years, recognition of the importance of document management has been increasing as part of work efficiency improvement. Under such circumstances, an electronic filing device is used to effectively use an office space and rationalize document retrieval work. Therefore, the user is demanding to provide an electronic filing device with improved operability by improving the user interface.

In the conventional electronic filing apparatus, when one or a plurality of originals are set on the scanner, the set originals are conveyed one by one to the reading section of the scanner, where the information on the originals is optically read. . The read information is converted into an electric signal, then binarized, and recorded in a storage medium such as an optical disk.

When the original to be read has information written on both sides, the front side and the back side are continuously read, and then the data is edited so that the front side and the back side of each original are continuous, and a single file is created. It is recorded in the storage medium.

[0005]

However, in the above-described conventional electronic filing apparatus, when recording a double-sided original, all pages are stored on both the front and back sides. Even if it is a double-sided original, it is rare that information is written on the back side of all the originals, and in many cases, there are mixed originals whose back side is blank. When recording such an original,
Since a blank page is recorded, it has a problem that it becomes a major factor of reducing the use efficiency of the storage medium. In view of this point, an object of the present invention is to provide an electronic filing device in which the usage efficiency of a storage medium is improved.

[0006]

In order to solve the above problems, the present invention comprises a first image reading means for reading information on the front side of a document and a second image reading means for reading information on the back side of the document. Document combining means for combining the image data read by the first image reading means and the second image reading means as one document data,
The document synthesizing unit stores the document data synthesized by the document synthesizing unit, and the synthesizing unit has a unit for excluding the blank page information of the information on the back side of the document when synthesizing the document data.

[0007]

According to the present invention, by the above means, when a plurality of double-sided originals are registered in the electronic filing apparatus, it is possible to exclude the part having a blank back side for registration.

Becomes

The operation of the electronic filing apparatus of the present embodiment having the above-described structure will be described below with reference to the flow charts of FIGS. 4 to 6.

When the user sets the original on the image scanner 10 in such a direction that the surface of the original becomes the reading surface, and in step 1, when an instruction to start reading the front is given from the keyboard 8, the CPU 1 first causes the CPU 2 to execute step 2. At, the variable 1 for counting the surface is initialized to "1". Then, in the image scanner 10, the first original is conveyed from the set original, and the front surface of the conveyed original is read in step 3. The read original is recorded in the document data storage unit 7 of the external memory 5 in step 4, and in step 5, the document data storage unit 7 recorded in step 4 in the surface information storage unit 52.
Set the storage address in.

After setting the address in the surface information storage section 52,
If the original set in the image scanner 10 remains in step 6, the variable 1 is updated to "+1" in step 7 and the process returns to step 3. If not, the reading of the front side is completed.

After reading the front surface, the back surface is read. The user sets the original on the image scanner 10 so that the back surface of the original becomes the reading surface, and then step 1
In step 1, when there is an instruction to start reading the back surface from the keyboard 8, first, in step 12, the CPU 1 initializes a variable m for counting the back surface to "1". Where C
In step 13, the PU 1 checks the blank document information storage unit 51 to see whether the back side of the document to be read is set as a blank sheet.

If the page to be read is not set as a blank page, the image scanner 10 reads the corresponding page in step 14, and step 15
In, the read page data is the document data storage unit 7
Memorized in. Then, at step 16, the back side information storage unit 53 stores the data in the document data storage unit 7
The address inside is written and the corresponding blank page flag is set to "0".

If the page to be read is set as a blank page, in step 17, the image scanner 10
Then, the information is not read, and the corresponding document is idly fed. Then, in step 18, NULL data is set in the portion where the storage address of the m-th page data of the back surface information storage section 53 is written, and the blank page flag corresponding to it is set to "1".

After the processing from step 14 to step 16 or the processing from step 17 to step 18, the CPU 1 in step 19 checks whether or not the document set in the image scanner 10 remains, and still reads it. If there is a manuscript, the variable m is updated by "+1" in step 20, and the process returns to step 13,
If there is no original, the data on the front side and the data on the back side are combined into one document data by the processing from step 31.

First, the CPU 1 initializes the variable i for total page management to "1" at step 31, and at step 32, sets the variable j for front surface data counting and the variable k for back surface data counting to "1", respectively. After initializing to
Data are combined by repeating the processing from step 33 to step 39.

At step 33, the storage address of the page j data set in the surface information storage section 52 is set as the storage address of the i-th page data of the document management data in the document management section 6, and at step 34, The variable i is updated by "+1".

Next, in step 35, the blank page flag of the data corresponding to the k-th page on the back side is checked in the back side information storage section 53, and if the value of the flag is "1", the process directly proceeds to step 38. The process is transferred and the flag value is "0".
If so, the processes of step 36 and step 37 are performed.

In step 36, the storage address of the k-th page data set in the back surface information storage section 53 is set to the storage address of the i-th page data of the document management data in the document management section 6, and the following step At 37, the variable i is updated by "+1".

Here, in step 38, the CPU 1
Judges whether the processing of all the read front and back data has been completed, and if there is still data to be processed, in step 39, the variable j and the variable k are respectively set to "+1".
After updating, the process returns to step 33, and if there is no data to be processed, step 40 and step 4
Process 1 is performed.

In step 40, the value obtained by subtracting "1" from the value of the latest variable i is set as the number of pages of the document management data of the document management section 6, and in step 41, based on the input from the keyboard 8. Register the document name and finish the process.

As described above, according to the present embodiment, when a double-sided original is registered in the electronic filing device, it is possible to specify a blank back side and exclude the specified page at the time of registration. Therefore, it is not necessary to record unnecessary data, and the storage device can be used efficiently.

In this embodiment, the blank page is designated, but the original having the information to be registered on the back side may be designated.

Although the user has designated from the keyboard 8 that the back side of the manuscript is blank, the manuscript is first read unconditionally before it is judged in step 13 whether or not it is a blank page. The number of pixels in the pixel is counted, and if the number is less than or equal to a predetermined value, it is determined as a blank page, and the process of step 18 is performed through step 13. If it is greater than or equal to the predetermined value, it is determined that the page is not a blank page and step 15 Also, the processing of step 16 may be performed.
