Abstract

PURPOSE:To reduce the burden of an operator, and simultaneously, to speed up a processing by generating partition position information based on a relation between picture data on the front surface of an original and the picture data on the back surface of it. CONSTITUTION:Picture information on both the front and the back surfaces of the original is read by a scanner 1, and the data quantity of each read page is measured by a counter 7. Then, the measured data quantity of the front page of the original and the measured data quantity of the back page are compared, and the partition position information of the picture information is generated according to this compared result. Consequently, by storing this partition position information while relating it to retrieval information, for instance, or storing this partition information as the retrieval information, the partition work at every title by the operator is eliminated when plural originals are recorded. Thus, the burden of the operator can be reduced, and simultaneously, the processing can be speeded up.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an information file device that searches and reads out desired image information as needed from among various types of image information stored in a storage device. [Prior Art] Recently, a large amount of image information such as texts and drawings is read by optical two-dimensional scanning, and this read image information is sequentially stored in a storage device, and each stored image is An information file device has been developed and put into practical use that makes it possible to read out necessary image information immediately by attaching search information to the information. FIG. 8 is a block diagram showing the general configuration of such an information file device. In this information filing device, the scanner 1 first reads a document to be filed. This scanner 1 performs processing such as binarization on an optically read image, converts it into image information by displaying a dot pattern, and outputs it to an image memory 2. The image memory 2 temporarily stores the dot pattern given from the scanner 1 as dot data for at least one page. The data stored in the image memory 2 is then sent to the display memory 3 and displayed on the display device 4.
is displayed. After confirming the image displayed on the display device 4 in this way, the operator operates the keyboard 5 to enter index information (consisting of file name, date and time, symbol, etc.) as appropriate, and executes the file execution of the image information. Give instructions. As a result, the image information displayed on the display device 4, that is, the image information stored in the image memory 2, is sent to the encoding/decoding circuit 9, compressed by encoding, and then stored in the storage device 10. The data is sent and written to a predetermined area of the storage medium. On the other hand, when the index information inputted from the keyboard 5 is written to the storage medium by the storage device 10, the index information input from the keyboard 5 is stored on the common storage medium in a state associated with the position information on this storage medium. Or stored in a predetermined area of another storage device. When reading the image information filed in the information file device as described above, the operator first inputs index information attached to the required image information by operating the keyboard 5. Here, the system control circuit 6 searches the input index information and reads out the position information of the corresponding image information. This read position information is then sent to the storage device 10, and the image information written at the corresponding position on the storage medium is read out. This image information is compressed and encoded, and is sent to the encoding/decoding circuit 9, where it is decoded into the original dot data. This dot data is then sent to the image memory 2 where it is temporarily stored, and further transmitted via the display memory 3 to the display device 4.
Or it is transferred to the printer 11 and output. [Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, in order to immediately read out the necessary image information from the image information on the storage medium, the operator has to distinguish between pieces of information when storing the image information. The index information must be entered in advance using a keyboard, etc. Therefore, when repeating the process of storing multiple pages of image information for one title, if you try to input all of the image information consecutively, the operator will need to check the divisions between each title by scanning the scanner 1. It is not possible to leave the system while it is in operation, which is a huge burden, and it is difficult to increase the input speed, which also has the disadvantage of often leading to omissions in the input of index information, etc. ．． In addition, in order to separate information from each other, it has been put into practical use to insert special paper, such as paper with sharp edges or paper with a specific color, for each title. There was also the disadvantage that the process of inserting special paper for each title was cumbersome. SUMMARY OF THE INVENTION An object of the present invention is to provide an information file device that can automatically divide stored information by title without imposing a burden on the operator. [Means for Solving the Problems] The present invention provides an information file device that searches and reads desired image information from a storage device storing a plurality of pieces of image information, including a reading unit that reads image information on both the front and back sides of a document; A measuring means for measuring the amount of data on each page read by the reading means, a comparing means for comparing the amount of data on the front page and the amount of data on the back page of the manuscript measured by this measuring means, and It is characterized by having a delimiter position generation means for generating delimiter position information of image information. [Operation] In the present invention, since the delimiter position information is generated based on the relationship between the image data on the front side and the image data on the back side of the document,
For example, by storing this delimiter position information in relation to search information, or by storing this delimiter position information itself as search information, when recording multiple manuscripts, the operator can separate each title. This eliminates the need for additional work, reduces the burden on the operator, and eliminates input errors. Furthermore, when reading each manuscript, there is no need for an operator to intervene, making it possible to speed up the processing. [Embodiment] FIG. 1 is a block diagram showing an information file device according to an embodiment of the present invention. In the figure, the same components as those shown in FIG. 8 above will be described with the same reference numerals. The scanner 1 automatically and continuously optically reads both the front and back sides of a document, performs processing such as binarization, converts the optical image of the document into image information displayed in a dot pattern, and converts this dot data into an image. Memory 2 and data amount counter 7
This is what is output to. The image memory 2 stores dot patterns sent from the scanner 1 or the encoding/decoding circuit 9 for each document as dot data. The display memory 3 stores the dot data stored in the image memory 2 and displays it on the display device 4 by transferring the dot data. The keyboard 5 is operated by the operator to input search information for image information to be filed into the information file device of this embodiment, or to give various instructions. The system control circuit 6 controls the entire information file apparatus of this embodiment, and controls each component circuit of the information file apparatus according to instructions given from the keyboard 5. The data amount counter 7 counts the dot data sent from the scanner 1 separately for the front and back sides of each page. The data amount comparison circuit 8 compares the amount of data on the front and back sides of one page of the document counted by the data amount counter 7, and determines that the information is separated when the amount of data on the front and back sides is reversed.
This determination result is output to the system control circuit 6. When the encoding/decoding circuit 9 writes the image information for one document stored in the image memory 2 to the storage medium of the storage device 10 and stores it, the encoding/decoding circuit 9 converts the amount of data into a known compression encoding method. When this compressed encoded image information is read out from the storage medium and written into the image memory 2, it is decoded and converted into dot data. The printer l1 prints the dot data stored in the image memory 2 on appropriate paper to make a hard copy. The storage device 10 stores encoded image information, search information input through the keypad 5, and delimiter information of continuous image information output from the system control circuit 6 based on the determination result obtained by the data amount comparison circuit 8. is stored on a storage medium. FIG. 2 is a flowchart showing the storage operation of image information in the information file device configured as described above. First, the operator sets single-sided originals for multiple titles on the scanner 1 (S L). In this manuscript, each title spans many pages. At this time, for example, if the manuscript is a single-sided manuscript filed in a binder with a heading attached to each title, the operator will pull out the manuscript every other time for each heading, as shown in Figure 3. Set it on scanner 1 in the reversed state. When the system control circuit 6 receives a start instruction from the keyboard 5 (S2). Scanner 1 automatically reads both the front and back sides of the set multiple originals (S3
). The read signal is sent to the image memory 2 and data amount counter 7. As a result, dot patterns on the front and back sides of each image document are stored in the image memory 2 (S4).
The system control circuit 6 transfers the image information stored in the image memory 2 to the encoding/decoding circuit 9, and after encoding, transfers it to the storage device 10 and stores it in the image information area of the storage medium (S5). ．． Further, the data sent to the data amount counter 7 is counted by the amount of data on the front and back sides (S6). Further, the data is transferred to the data amount comparison circuit 8. The data amount comparison circuit 8 has a function of determining that it is a break in input information when the data amounts on the front and back sides are reversed. Therefore, when a one-sided document is read by the scanner 1 while being turned over for each title, each time the reversal is confirmed, it is determined as a delimiter of image information (37). This result information is stored in the search information area of the storage medium of the storage device 10 via the system control circuit 6 (Sa). On the other hand, the system control circuit 6 stores the index information input from the keyboard 5 in the search information area of the storage medium of the storage device 10 (
S9). In other words, after the operator has stored all the manuscripts of the plurality of titles in the information file device, if the operator inputs the index information of each title in order from the beginning using the keyboard 5, the information will be automatically stored in the search information area. The delimiter position information and its index information are associated in the system control circuit 6. FIG. 4 is a flowchart showing the operation when reading image information of a plurality of titles filed in the information file device as described above. First, the operator inputs the index information of the image information that he/she wishes to read by operating the keyboard 5 (S11), whereby the system control circuit 6 searches the input index information in the search information area on the storage medium. and read out the index information number from the beginning (S 1 2)
．． Then, image information corresponding to the index information is read out based on the above-mentioned image information delimiter position information (S13). The system control circuit 6 restores the read image information to dot data using the encoding/decoding circuit 9 (514). Transfer the image to the image memory 2 and store it (S15). Thereafter, based on the operator's instructions, the dot data in the image memory z is transferred to the display device 4 or the printer l1 and output (3 1 6). Note that instead of searching for image information using index information as described above, it is also possible to search by locating the desired break position of image information using only the break position information of the image information. Further, in the above embodiment, the data amount comparison circuit 8 determines whether the data amounts on the front and back sides have been reversed, and when the data amount has been reversed, it is stored as position information in the search information area of the storage medium as an information delimiter. However, the data amount comparison circuit 8 may be configured to determine that there is a break in information when the amount of data on the back side is greater than the amount of data on the front side. In this case, as shown in FIG. 5, the operator only has to set a plurality of manuscripts in the scanner, each of which has a blank heading sheet with index information written on the back side inserted for each title. Therefore, there is no need to turn over the manuscript for each title as in the above embodiment, and the manuscript can be stored in the information file device in a binder or the like in a 7-eye state. In addition, in this way, as in the above embodiment, the delimiter for each title is automatically stored not only for single-sided manuscripts but also for double-sided manuscripts, allowing desired information to be searched. Further, in the above embodiment, the data amount is counted by the data amount counter 7 provided immediately after the scanner 1, but as shown in FIG. This may be done based on the count of the amount of data after compression encoding. In particular, when transferring compression-encoded data to the storage device 10, it is necessary to count the amount of data in advance and output it to the storage 10 as address allocation information. It has a counter. Therefore, if the data amount comparison circuit 8 is provided after the encoding/decoding circuit 9 and is controlled by the system control circuit 6 as in the above embodiment, image information input and retrieval can be performed in the same manner as in the above embodiment. be able to. In particular, by counting the amount of data after compression encoding, even if a heading with black and white stripes is inserted for each title, as shown in Figure 7, delimiter information for each title is created. By changing the width of these black and white stripes as appropriate, identification numbers can be automatically assigned to the divisions. By storing the identification numbers attached to these divisions as search information in the search information area of the storage medium, an identification function is added to the mere divisions, and a desired document can be searched for by the identification number regardless of the order in which the image information is stored. It becomes possible to read. Furthermore, by configuring the storage device 10 and the system control circuit 6 so that some kind of title corresponds to the identification number assigned to each section, the operator can enter the title etc. as index information using the keyboard after inputting the information. 5 eliminates the need for input, making it possible to completely automate the input of image information to the information file device. [Effects of the Invention] According to the present invention, the separation position information is generated based on the relationship between the image data on the front side and the image data on the back side of the document. This eliminates the need to attach marks, reducing the burden on the operator. Furthermore, operator input errors can be reduced, image information can be stored continuously, and processing can be speeded up.
