Abstract

PURPOSE:To securely read a bar code even if the conveying direction of a document is changed according to the shape of the document by selecting the read direction of a bar code scanner optionally for the conveying direction of the document. CONSTITUTION:The bar code scanner 7 is provided with a rotary shaft 7a and a pulley 7b at one end part of the shaft 7a is connected to a motor 9 through a belt 8 to rotate the scanner 7 in 90 deg. units by the rotation of the motor 9, thereby changing the scanning direction. Then the document 1 to which the bar code 23 is added is conveyed from a paper feeding tray 2 and the scanning direction of the scanner 7 is determined according to the photographic direction of the document 1 to read the bar code 23. Then a document where a conveyance defect or read defect occurs is discharged to a defective paper discharging tray 13 and a document 1 where no error is detected is photographed by a camera 16 and discharged to a normal paper discharging tray 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method of photographing a sheet member such as a slip to which code information such as a bar code is attached on a microfilm, and photoelectrically reading this code information. The present invention relates to an information reading device capable of reading information.

[Prior Art] Conventionally, in order to reduce the storage space for documents such as vouchers that are ordered in large quantities, image information has been stored on microfilm, optical disks, magnetic disks, and the like. but,
Easily search for this information at a later date (hereinafter referred to as search)
In order to make this possible, it is necessary to input search information (hereinafter referred to as an index) corresponding to each piece of information, and it takes a huge amount of time to input this index. Therefore, one way to solve this problem is to add code information such as a barcode that will serve as an index to the above document, and to send this code information to a barcode scanner or MI.
An information reading device as shown in FIG. 6 has been devised as an information reading device that captures image information on a document and records the image at the same time as it is read by a reading mechanism such as CR or OCR.

This device holds a document 100 such as a slip to which a barcode is attached as an index to rollers 101, 102 and 1.
The document 100 is conveyed one by one toward the paper output tray 108 by a conveying means consisting of a belt 104 and a belt 104, and the barcode is read by a barcode scanner 105.
It is photographed and made into microfilm. The barcode read here was input into a computer and could be searched easily and reliably at a later date.

[Problems to be Solved by the Invention] However, in the conventional example described above, since the barcode scanner 105 is used in a fixed manner, the reading scanning direction (hereinafter referred to as the scanning direction) of the barcode scanner 105 is determined automatically. It was to be done.

In other words, the conveyance direction of the document 100 is limited to only one predetermined direction corresponding to the scanning direction, and if the conveyance direction of the document 100 is set to a direction different from the scan direction, the document 100 will not be able to read the barcode. The camera i07 is transported to the photographing unit 106 without being photographed.
It will be photographed.

Incidentally, there is an optimal photographing direction in which the document 100 is photographed by the camera 107 so that efficient photographing can be performed according to the shape of the document 100.
The optimal photographing direction in step 7 and the above-mentioned scanning direction do not necessarily match, and for the reasons mentioned above,
Since the conveyance direction of the barcode scanner 105 is set based on the scanning direction of the barcode scanner 105, for example, as shown in FIG. 7, very inefficient photographing may be required.

The present invention has been made to solve the problems of the prior art described above, and its purpose is to reliably read code information on a document regardless of the direction in which the document is conveyed.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a conveyance means for conveying a document to which code information has been added, and a predetermined code information of the document conveyed by this conveyance means. In the information reading apparatus, the reading scanning direction of the reading means can be arbitrarily selected with respect to the conveyance direction of the document.

[Function] In the present invention having the above configuration, by making it possible to arbitrarily select the reading scanning direction in the reading means,
Even if the conveyance direction of the document is changed depending on the shape of the document, the code information attached to the document can be reliably read.

[Embodiment] A first embodiment of the present invention is shown in FIGS. 1 to 4, and its structure will be explained based on FIGS. 1 to 3.

1 is a manuscript with a barcode attached as code information, 2
3 is a paper feed tray that stores the original 1, 3 is a paper feed sensor that detects the presence or absence of the original 1, and 4 is a transport roller that transports the original 1. A transport belt 5 is attached to the transport roller 4. . Reference numeral 6 denotes a position sensor for detecting whether or not the document l is at the reading position of a barcode scanner 7 as a reading means. is provided with a pulley 7b. This pulley 7b is connected to a motor 9 via a drive belt 8, and the rotation of this motor 9 allows the barcode scanner 7 to rotate in 90'' increments, making it possible to change the scanning direction.10 11 is a solenoid that is driven and extends when a conveyance defect such as double feeding or transportation is detected, or when a bar code as code information is not read properly, and 11 is a conveyance path that changes depending on the solenoid IO. Reference numeral 12 denotes an ejection roller that sends out originals for which transport defects such as double feeding or transportation have been detected, or originals for which barcode reading errors have occurred (hereinafter referred to as defective originals) to the defective ejection tray 13. Reference numeral 14 represents an ejection belt. This is a delivery roller that drives the delivery belt 15, and serves as a recording means provided above the trajectory of the delivery belt 15, which records a document that has been correctly transported and has had its barcode read (hereinafter referred to as a normal document) at a predetermined position. The normal document is conveyed to be photographed by the camera 16, and the normal document is discharged onto the normal paper output tray 17. 18 is a data processing machine (hereinafter referred to as a computer) having a key manual section 1g. , an index is created from the code information read by the barcode scanner 7.

Next, an example of the operation of this embodiment will be explained based on FIG. 4.

First, when photographing a document 1 with a barcode attached, turn on the power switch of the main body (STEP 1), then determine the scanning direction of the barcode scanner 7 according to the photographing direction of the document 1 ( STEP 2). Then, the paper feed sensor 3 detects whether or not the document 1 exists on the paper feed tray 2.
5TEP, , 3) If there is no document 1, the operation ends 5TEP 4) If it is detected, the paper is fed by the transport roller 4 after a predetermined timing (STEP
5). Then, a detection means (not shown) checks for conveyance defects (STEP 6) and checks for barcode reading (STEP 7). If an error occurs in either of these, the solenoid 10 is driven to extend the barcode. 5TEP 8), the conveyance path 11 is changed upward, and the document 1 is discharged to the defective paper discharge tray 13 by the discharge roller 12 (STEP 9). Then, the solenoid 10 returns to the predetermined position again (STEP
IO). Also, document 1 in which no error was detected
is sent by a delivery belt 15, and a camera 16 is sent to a predetermined position.
After photographing (STEP II) Normal paper output tray 17
(STEP 12). Note that the read barcode information is sent to the computer 18, and an index is created within the computer 18.

Next, a second embodiment of the present invention is shown in FIG. 5, and the same parts as in the first embodiment will be described with the same reference numerals.

The reading means in this embodiment uses a laser beam and reads the reflected light, and the laser beam emitted from a laser beam gun (not shown) installed near the line image sensor 2o such as COD is polygon mirror 21
is reflected and transmitted through the prism 22 whose plane is trapezoidal,
This corresponds to barcode 23 on document 1. The reflected light that hits the barcode 23 travels in the opposite direction along the optical path described above and is read by the line image sensor 20. Here, by rotating the polygon mirror 21 in the direction of arrow X in the figure, the barcode 23 is scanned in the direction of arrow X in the figure, but if the prism 22 is rotated by 45 degrees in the direction of arrow B in the figure, the barcode 23 is scanned in the direction of arrow B in the figure. direction is 90°
It rotates in the direction of arrow Y in the figure. That is, prism 2
Barcode 23 on document 1 can be read by simply rotating 2 by 45 degrees.
The scanning direction can be changed by 90''.

Therefore, since the movable parts can be made smaller compared to the first embodiment, the device main body can also be made smaller.

Since the other configurations and operations are the same as those of the first embodiment, their explanations will be omitted.

[Effects of the Invention] As explained above, in the present invention, code information attached to a document can be reliably read even if the conveyance direction is changed depending on the shape of the document, so that the photographing direction of the document can be changed. can be freely selected, allowing for efficient photographing of originals.
