Abstract

PURPOSE:To read a bar code in a still state, to repeat reading until it can be read out correctly and to enhance accuracy by discharging a sheet after the bar code is read out of the sheet in a container. CONSTITUTION:One side of the container 1 which piles and contains the sheet 2 is made up of a transparent plate 1a. The bar code 2a is printed on the front of the sheet 2 whose inner side comes into contact with the transparent side. The code reading part 4a of a bar code reader 4 is installed so as to face the transparent 1a. When a read command is issued from a control part 5, the reading part 4a reads the bar code 2a through the transparent plate 1a, and transmits it to a host computer through the control part 5. Then the host computer instructs the control part 5 to discharge the sheet, and processes data. According to the discharge command, a discharge mechanism 3a isolates and discharges one sheet 2 in the container 1. In accordance with a selection signal, the attitude of a sheet selection mechanism 6 is varied to recognize whether the sheet is discharged or not, and the sheet is contained in a stacker 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a barcode reading device, and more particularly to a barcode reading device that reads barcodes of sheets of paper stored in a hopper in a stationary state and then discharges the sheets.

(Prior Art) Conventionally, a device as shown in FIG. 3 has been generally used as a method for reading barcodes from a stack of sheets of paper with barcodes such as slips.

In FIG. 3, sheets 2 such as slips and the like stored in the hopper 11 are discharged one by one from the lower part of the hopper 11 by the discharge mechanism 132, and are conveyed by rollers 13b and 13C for feeding the sheets 1.1. Sent in the direction of the middle arrow.

During the conveyance, the barcode attached to the paper 2 is read by the barcode reader 14, and the result is sent to the computer 15 as an output signal.

In this way, the barcode is read by using the movement of the paper 2, and the paper 2 such as slips that have been read are stored in the stacker 17.

(Problems to be Solved by the Invention) As mentioned above, the conventional barcode reading device reads the barcode while moving the documents taken out one by one from the hopper and stacks them on the stacker. Even if this occurs, it will be accumulated in the stacker as it is.

Therefore, there is a drawback that in order to read the paper again, it is necessary to load the ejected paper back into the hopper.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such drawbacks and to provide a barcode reading device that is more reliable than conventional barcode reading devices by discharging only those that have been completely read.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the barcode reading device of the present invention includes a container 1 in which a large number of papers 2 having barcodes 2a to be read can be stacked therein; , container 1
a discharge mechanism 3a capable of discharging sheets one by one from a barcode; a barcode reader 4 for reading the barcode;
It has a control unit 5 that controls the ejection mechanism 3a, and a part of the container 1 is made into a transparent structure 1a, and the barcode 2a of the paper type 2 that is accommodated in the container 1 and contacts the transparent structure 1a from the inside and the barcode reader 4. The barcode reading section 4a has a transparent structure 1a.
They are arranged so as to face each other with the barcodes 2a interposed therebetween, and under the control of the control unit 5, the ejecting mechanism 3a sequentially ejects the sheets 2 from the container 1 after reading the barcode 2a.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a barcode reading device according to the present invention, and a stacker, stacker, etc. are shown in cross section.

FIG. 2 is a perspective view showing essential parts of the embodiment shown in FIG. 1.

As shown in Figures 1 and 2, paper 2 such as slips etc.
One side of a container (hopper) 1 that can be stacked with items is made of a transparent plate 1a.

A barcode reading section 4a of a barcode reader 4 is located at a position facing the barcode 2a printed on the surface of the paper 20 that contacts the transparent plate 1a from the inside with the transparent plate 1a in between.
The barcode reader 4 has a structure (not shown) that can be adjusted so that the distance is adjusted.

Note that the barcode reader 4 uses a stationary barcode reader that can read barcodes while remaining stationary on the barcode.

The rollers 3a, 3a are for discharging sheets one by one that are in contact with the transparent plate 1a from the inside, and rotate in the direction of the arrow in the figure when discharging the sheets.

The rollers 3b and 3c form a pair, one of which is constantly driven to push the paper 2 downward.

When the paper sorting mechanism 6 wants to store the paper 2 in the right part of the stacker in FIG.
If you want to store it in the left part of the figure, take the position shown by the two-dot chain line in the figure.

The rollers 3a, 3b and the paper sorting mechanism 6 are driven by a drive mechanism such as a motor (not shown) controlled by the control section 5.

Next, the operation will be explained.

As shown in FIG. 2, the sheets 2 are placed one on top of the other with the transparent plate 1a in between so that the barcode 2a is positioned in front of the barcode reading section of the barcode reader 4.

Therefore, when a reading command is issued from the host computer via the control unit 5, the barcode reader 4 reads the transparent plate 1a.
The barcode 2a written on the slip 2 is read through the controller 5, and the read data is transmitted to the external host 1-computer via the controller 5.

When the host computer receives this data, it orders the control unit 5 to eject the slip, processes the data, and, if necessary, sends out a selection signal for the slip, etc.

When the control unit 5 receives the ejection command signal, the ejection mechanism 3a separates and ejects the slip 2 in the hopper 1, and changes the attitude of the paper selection mechanism 6 in response to the selection signal to remove the ejected paper. are selected depending on whether they are applicable or not, and are stored in a storage location provided in the stacker 7.

Since the present embodiment operates as described above, the paper is not ejected to the outside unless the hard code is completely read.

Further, since the structure is as described above, when this embodiment is used, various paper sorting machines that are integrated with a barcode reading device can be easily obtained.

(Effects of the Invention) As explained above, the present invention reads a barcode from a sheet of paper while it is still in a container, and then ejects the sheet from the container. Since the paper is ejected from the printer, the reading operation can be repeated until it can be read correctly, improving the reading accuracy.

Further, unlike conventional devices, when there is a reading error, the reading is performed again, so there is no need for troublesome operations such as putting the ejected paper back into the container again.

As a result, a highly reliable device is obtained.
