Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scanner device provided with an automatic document feeding means for feeding a document to a document reading means. The present invention relates to a scanner device capable of preventing occurrence of a missing page.

[0002]

2. Description of the Related Art Conventionally, in this type of scanner device,
When an ADF (Auto Document Feeder) takes in a document with pages such as a book and conveys it, a plurality of documents are taken in at the same time, causing missing pages to be taken in. As a result, the data of the read document is transferred to the PC.
(Personal computer) or the like, the page number of the actual document and the registered page number may be shifted.

In order to correct this, data of each registered page is first examined one by one to find out which page has been missed, and the registration number of the page that has not been missed is replaced with the actual page number. Then, it was necessary to read the missing page separately. Such a correction work is very troublesome, and the trouble increases as the number of missing sheets increases.

In order to solve such a problem, for example, Japanese Patent Application Laid-Open No. Hei 5-273812 discloses a method in which a position at which a page number is written on a manuscript paper is designated in advance by a position designation unit, and the position designated at the time of copying is designated. There has been proposed an apparatus in which a page number is read by a reading sensor and the read page numbers of a leading page, a last page, and a missing page are displayed on a display unit so that a copy omission can be automatically confirmed.

[0005]

However, in the apparatus described in Japanese Patent Application Laid-Open No. Hei 5-273812, a position designating section for designating a position where the page number of the document is written in advance, and a position designating section for the document in advance. A sensor for determining the page number written at the designated position is required, which causes an increase in cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and detects the occurrence of a page omission by a simple configuration.
An object of the present invention is to provide a scanner device capable of matching the page number of an actual document with the registered page number.

[0007]

According to the present invention, there is provided a scanner device comprising: a document reading means for reading a document; and an automatic document feeding means for transferring the document to the document reading means. And a counter for counting the number of documents taken in by the automatic document feeder.

Thus, the sensor can detect that a plurality of originals have been taken in at the same time, and the counter means can detect the number of originals that have been taken so far (where the plurality of originals have been taken in). Then, the occurrence of a missing page is automatically determined, and the page number of the document and the registration number can be matched except for the portion where the missing page occurs.

Further, as the sensor, a relatively inexpensive sensor such as a photo sensor and a pressure sensor capable of sensing the number of documents to be taken can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the scanner device of the present invention will be described below with reference to FIGS. Here, FIG. 1 is a block diagram showing a schematic configuration in the present embodiment, and FIG. 2 is a flowchart showing a document taking operation in the present embodiment.

In FIG. 1, reference numeral 1 denotes an original transport driving unit for automatically taking in and discharging an original, 2 an original reading unit for reading (scanning) the original transported by the original transport driving unit 1, and 3 an original transport driving unit. Reference numeral 1 is a document number detection sensor that detects the number of captured images when the document is automatically captured.

Reference numeral 4 denotes a counter unit which counts and records where multiple sheets have been captured based on information from the number-of-documents detection sensor 3, and 5 denotes a document read by the document reading unit 2. This is a data registration device for registering scan data and registering information on where and how many sheets are simultaneously detected detected by the counter unit 4.

In the above-described configuration, as the number-of-documents detecting sensor 3, a photo sensor or a pressure sensor capable of detecting the number of taken-in documents is used. This photo sensor or pressure sensor is arranged at the document inlet.

That is, when detecting the number of originals by using a photosensor, the reflectance is higher when the photosensor is loaded with two originals than when one original is imported. Take advantage of that. However, 1
Since the reflectance of a sheet varies depending on the paper to be scanned, sampling may be performed at the time of preview performed before scanning.

When the number of originals is detected by using a pressure sensor, the weight of one original is weighed to determine whether one original or a plurality of originals have been captured at the same time. Can be detected by the weight of

Further, the data registration device 5 is constituted by a PC or the like, and adds a registration page number so as to match the page number of the read document based on the missing page portion determined by the counter unit 4. Along with
Prompts the user to scan the portion where the missing page has occurred again.

This eliminates the need to check the coincidence between the document page number and the registered page number and re-register the registered page number, thereby greatly improving the efficiency of the operation.

The document taking-in operation of the scanner configured as described above will be described with reference to the flowchart of FIG. First, before you start importing your manuscript,
At the same time as previewing the size of the manuscript paper, the output data of the manuscript number detection sensor 3 when one manuscript paper is taken in is transferred to the counter unit 4 and held therein (step 1).

Then, automatic document taking-in is started (step 2), and every time a document is taken in, the document number detecting sensor 3
Is compared with the stored data (step 3), and when it is determined that a plurality of originals have been taken in at the same time, the number of simultaneously taken originals is counted by the counter unit 4 at that time. The result is registered in the data registration device 5 together with the counting result (step 4). If it is determined that only one sheet has been normally captured, it is determined in the next step whether or not all the originals have been captured.

Then, it is determined whether or not all the originals have been captured (step 5). If all the originals have been completed, the process ends (step 6). If all the originals have not been completed, the process returns to step 2. Then, the original is taken in.

As described above, since data indicating which portion and how many originals have been simultaneously captured can be registered in the data registration device 5, the data registration device 5 uses the data based on the data. The registration page number is added so as to match the page number of the read document, and the user can be prompted to scan the portion where the missing page has occurred again.

[0022]

Since the scanner device of the present invention has the above-described configuration, it is possible to detect the occurrence of a missing page with a simple configuration and to match the actual document page number with the registered page number. .
