Abstract

PURPOSE:To read out the picture information on a registered original in the order of pages by registering the picture information read out of a 2-sided original together with the page number of the original and the discrimination information on both sides of the original. CONSTITUTION:The picture data on both sides of originals 1-5 are registered successively to the sequential physical sectors in such order as shown in the figure. The page numbers and the label data on the page control information on each of both sides of a series of 2-sided originals are recorded to logical sectors 1-10 respectively. These physical sectors where the picture data are registered and logical sectors where the label data on the page information are recorded are set opposite to both sides of the sequential originals, i.e., to the order of pages respectively as shown in the figure. Then those data are read out of an optical disk after the automatic registration is through with a series of 2-sided originals according to the page information recorded to the logical sectors. Then the control is given so that the picture data on the registered originals can be read out in the original page order of the 2-sided originals.

Description

[Detailed Description of the Invention] [Technical Field] The present invention provides an automatic document registration method in which image information for each page of a sheet document is continuously fed and sequentially read, and is stored and registered in a storage device such as an optical disk. In particular, double-sided originals can be automatically registered so that they can be reproduced in page order.

[Prior Art] Generally, in an image file system using a storage device such as an optical disk that can store a large amount of information, a large number of documents containing information to be stored are automatically fed and the read information is registered. Adopting this type of automatic document registration method is an essential requirement due to the nature of the image file system.

However, in the conventional automatic document registration method, an automatic sheet document feeder is used to continuously feed the document to the document reader and read it, and the information read in the feeding order is registered in the image file in the same order. Therefore, the order of reading information from the image file is also the order of registration, and therefore the order of document feeding.When registering a single-sided document, it is not possible to automatically feed the double-sided document to the page type. The drawback is that a sheet document feeding device that is possible cannot be adopted.

[Objective] An object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to continuously feed a series of double-sided originals to a document reading device using a conventional automatic sheet document feeder, automatically register them, and register them. An object of the present invention is to provide an automatic document registration method that allows information on a document to be read out into pages.

[Representative Configuration of the Invention] That is, the automatic manuscript registration method of the present invention adds and registers the page number and front and back identification information of the manuscript together with the image information read from the double-sided manuscript.
The image information of the registered manuscript can be read out into pages.

[Example] In explaining the present invention in detail with reference to the drawings below, firstly, with reference to FIGS. 1 and 2, a sheet document automatic feeding reading storage device to which the present invention is implemented, namely: The configuration and operation of the automatic document registration device will be explained.

FIG. 1 is a perspective view schematically showing the appearance of the automatic sheet document feeder, and FIG. 82 is a longitudinal sectional view thereof.

In the figure, C is a two-dimensional scanning original reading device, and 2 is a platen, that is, a glass plate of an original plate, which is fitted and fixed into a window provided on the top plate of the outer box. This platen 2
is a part of the original exposure area.

The automatic sheet document feeder is disposed above the platen 2 described above, and is roughly divided into a document feeder section that includes a document stacking tray, that is, a sheet document stacking table L, that is, a document separation and conveyance section A, and a document setter section. B, a discharge tray 10 for normally running documents, a document traveling reversing section 5, and a discharge tray 8 for skewed documents.

The document feeder section A loads a series of double-sided documents set in this manner with the front side image side facing downward, and separates the set of double-sided documents one by one from the upper side and feeds them to the document center section B. Reference numeral 11 denotes a paper presence/absence detection switch sensor that detects whether or not a document is stacked on the document stacking tray l.

On the other hand, the document setter section B consists of a pickup roller mechanism 12 connected to the document feeder section A and an endless conveyor belt 3 that faces each other in close proximity to or in contact with the entire upper surface of the platen 2. The document fed out one sheet at a time is pressed against the platen 2 by the conveyor belt 3 and is conveyed while sliding the top surface of the platen 2 from right to left in the figure until the leading edge of the document reaches the reference position 4 on the platen 2. do. As a result, the original is conveyed to a predetermined position on the platen 2 and set.

In this state, the downward image surface of the set original is read by the original reading device C via the transparent platen 2. Thereafter, the document on the platen 2 is discharged to the normal traveling document discharge tray 10 disposed on the left side in the figure by the rotation of the endless conveyor belt 3 of the document setter section 8 again.

This document conveyance cycle is automatically and repeatedly carried out sequentially and repeatedly for each document in the series of documents loaded on the document stacking tray l, and after the entire front side of each of the series of double-sided documents has been continuously read, The double-sided originals stacked on the paper output tray 1O are transferred to the original stacking tray 1, and then stacked with the image side on the back side facing downward, and the above-described document feeding and reading are repeated to read the entire series of double-sided originals.
The read image information is recorded on the optical disc, and a series of document registration is completed.

At the starting end of the document conveyance path, at least one pair of infrared emitter 8 and infrared receiver 7, which are arranged opposite to each other across the conveyance path, detects skew or double feeding of the document being conveyed. The selection plate 8 is rotated based on the detected information, and the skewed original or double-fed original that is unsuitable for reading is conveyed to the paper ejection tray 6 and ejected.

Note that, after the feeding of a series of documents is once completed, these skewed or double-fed documents are transferred to the document stacking tray 1, and automatic feeding and automatic reading are performed again.

Next, the manner in which information such as document image data is stored by the above-mentioned optical disc will be explained with reference to FIG.

On an optical disk storage medium, storage information is managed in units of sectors divided into fixed storage capacities.In the figure, the smallest section surrounded by a solid line and a dotted line is an l sector 301. The image data transmitted from the document reading unit via the image data is stored in sequential sectors from the outer peripheral edge of the optical disk, that is, the upper edge of the recording medium schematically shown as a rectangular section in the figure, and the image data storage area is It is called an image area, and the sectors 301 that make up the image area 302 are called physical sectors.

On the other hand, control data regarding image data for each manuscript, that is, page numbers in a series of manuscripts,
Data such as the address of the corresponding physical sector is stored in sequential sectors from the inner edge of the optical disk, that is, from the bottom edge in the figure.The control data storage area is called a label area, and the sectors 301 constituting the label area 303 are stored as a logical area. It is called a sector.

Therefore, for an optical disk that manages and stores and registers each data related to a document as described above.

For example, when five double-sided originals are sent to a document reading device by an automatic sheet document feeder, read, and automatically registered, the page order of the document itself is sequential as shown in Figure 4 (A). This is an alternating order of front a and fold of manuscripts 1 to 5.

However, when automatically feeding double-sided originals, as described above, for a series of double-sided originals 1 to 5, first only the front side a is read, then only the back side is read, and the read image data is transferred to the optical disk in the order of reading. to be memorized. Therefore, the front and back sides of the original image data to be sequentially stored in the physical sectors 1 to 10 of the optical disk are as shown in FIG. 4 CB). Therefore, if the image data registered in this order is read out in the order of physical sector addresses without particularly managing the readout order, the front and back sides of the read image data will remain the same as shown in Figure 4 CB). The order is as follows.

In contrast, in the automatic document registration method of the present invention, the image data of the front and back sides of documents 1 to 5 are registered in sequential physical sectors in the order shown in FIG. 10, the page numbers of a series of double-sided manuscripts,
Record label data for page management information such as front and back,
The physical sector in which image data is registered and the logical sector in which page information label data is recorded are sequentially transferred to the front and back of the document.
That is, the pages are made to correspond to each other as shown in FIG. 4(C).

Therefore, when reading from an optical disk after automatically registering a series of double-sided originals, the image data of the registered originals should be controlled so that reading is performed according to the page information recorded in the logical sectors, and the image data of the registered originals can be read in the original page order of the double-sided original. I can do it.

Next, FIG. 5 shows an example of the circuit configuration of the automatic document registration apparatus according to the present invention.

In the figure, in the sheet document automatic feeders (A, B), the document reader t (C), and the optical disk device (0), which are respectively shown surrounded by chain lines, 501 is the document reader (

This is an image data bus that transmits image data to the management unit 513.

Reference numerals 513 and 514 refer to circuit portions that respectively manage storage data in the image area and label area on the optical disk device, and 515 refers to the label area management unit 513 and R, which will be described below.
This is a label data bus between AM81B and AM81B.

51B is the control line 50 from the skew/double fed document detection circuit 50B.

Data buses 513 and 520 between 13 and 514 and the optical disk 517 are switches for respectively starting the entire document registration operation and the front and back side identification information recording operation of a double-sided document.

In the automatic document feed reading/storage device according to the present invention, which includes the above-mentioned components, the central control circuit 501 is activated by the registration switch 519 or the skew registration switch 520, and the document loading information from the paper presence/absence detection switch sensor 11 is activated. Accordingly, the central control circuit 501 controls and operates the respective circuits of automatic sheet document feeders A and B and document reader C. Thereby, the image data read by sequentially conveying a series of documents is transmitted to the image area management section 513 of the optical disk device C, and is sequentially stored on the storage medium of the optical disk.

At the same time, the output tray selection circuit 50

In the process of automatic document registration described above, a front and back identification signal of the document being registered is sent from the central control circuit 501 to the control line 52 in accordance with the front and back identification information from the document front and back identification switch 520.
2 to the label area management section 514, the image data of the registered document stored in the physical sectors in the order shown in FIG. 4(B) is input from the document reading section 5011 via the control line 511. Based on the disc number count information, address information of logical sectors in the order shown in FIG. 4(C) is created and recorded and registered in the logical sectors of the optical disc.

Through the above operations, automatic registration of double-sided originals using the automatic sheet document feeder is performed.

FIG. 6 shows a flowchart for controlling the above-described operations in the present invention.

First, when the automatic document feeding reading storage device is activated in step SO, in step S1, a paper feeding operation is carried out according to the information of the switch sensor 11.In the next step S2, pages are counted, and after reading the document, In step S3, it is determined whether the read document is the front side or the back side based on the information of the document front/back identification switch 520. If the read document is the front side, the process proceeds to step S4, and if the document is the back side, the process proceeds to step S5, where front page and back page address information to be registered in the logical sector is created, respectively.

Next, in step S6, the address information is registered in the logical sector. In step S7, it is determined based on the information from the switch sensor 11 whether or not reading of the stacked originals has been completed, and if it has not been completed, the process returns to step Sl and sends the next original. On the other hand, if the process has been completed, it is determined in step S8 whether or not one skew feed has occurred, and if such an occurrence is detected, a re-registration operation is performed in step S8, and then the process proceeds to step SIO. On the other hand, if the process ends normally, the process directly proceeds to step SIO, and the series of operations ends here.
