Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a barcode reading device, and more particularly to a barcode reading device that statically reads the barcodes of sheets of paper stored in a hopper 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, papers 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 13a.
The paper is sent in the direction of the arrow in the figure by rollers 13b and 13c for paper transport.

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
The barcodes are read while the documents are taken out one by one from the hopper and stored in the stacker.
Even if a reading error occurs, it will be accumulated in the stacker.

Therefore, in order to read the paper again, it is necessary to place the ejected paper in the hopper again, which is a drawback.

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

(Means for Solving the Problems) In order to achieve the above object, a barcode reading device according to the present invention is capable of stacking a large number of sheets of paper bearing barcodes to be read, and at least reading the barcodes of the sheets of paper. a container having a transparent portion against which a coded portion is pressed; a barcode reader fixed to the transparent portion from outside of the container in opposing proximity to read the barcode; and a transparent portion of the container. an ejecting mechanism that ejects the paper sheets one by one from the container on the side where the paper sheets are placed; a control section that controls the ejecting mechanism based on the reading result of the barcode reader; and a control section that controls the ejecting mechanism based on a signal from the control section. is operated to sequentially discharge the sheets whose barcodes have been read from the container.

(Example) Next, an example 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 the hopper, 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 FIGS. 1 and 2, one side of a container (hopper) 1 into which papers 2 such as slips can be stacked is made of a transparent plate 1a.
The barcode reader 4 is placed so that the barcode reading section 4a of the barcode reader 4 is positioned opposite to the barcode 2a printed on the surface of the paper 2 that contacts the transparent plate 1a from the inside with the transparent plate 1a in between. can be adjusted by a structure not shown.

Note that the barcode reader 4 is a stationary barcode reader that can read barcodes while standing still 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 7 in FIG. 1, it takes the posture shown by the solid line, and when it wants to store the paper 2 in the left part of the stacker 7, it takes the posture shown by the two-dot chain line in the figure. Take.

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 stacked and stacked 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 barcode 2a written on the slip 2 through the transparent plate 1a, and transmits the read data via the control unit 5. and send it to an external host computer.

When the host computer receives this data, it instructs 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 posture of the paper selection mechanism 6 in accordance with the selection signal to select the ejected paper. , non-applicable, etc., and accommodate them in different accommodation locations provided in the stacker 7.

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

Further, since the structure is as described above, when this embodiment is used, various paper sorting machines 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, thereby reading the barcode in a stationary state and waiting until the reading is finished. 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 a reading error occurs, 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.
