JPS58192178A - Bar code reader - Google Patents

Abstract

PURPOSE:To attain simple reading without moving a reader only with the switch operation, by providing a switch for the reader to read bar code symbols of lots of same commodities and reading the symbols with a conventional method only at first. CONSTITUTION:In a pen type reader 4, a light from a light source 5 irradiates a bar code symbol of a recording medium 1, the reflected light is converted into an electric signal at a photoelectric conversion circuit 6 and applied to a recognizing circuit 7. The result of recognition is inputted to a control circuit 9 as bar code information and stored in a prescribed address of a storage circuit 8. In reading the same bar code symbol read before, the switch 3 provided for the pen type reader 4 is operated and a switch signal is inputted to a switch control section 10 for the reading. The information representing the number of operations of the switch is inputted to the control circuit 9, calculated with the information already stored in the storage circuit 8, and the result is stored in the other storage area.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention The present invention relates to a barcode symbol reading/<-code reading device.

Prior Art In department stores, supermarkets, etc., in order to identify large quantities of products, stickers with barcodes are attached to the products, and the barcodes are transferred to optical K1FF! A system is used to sell products or manage inventory.

As this type of barcode V reading device.

Barcodes affixed to products can be read by placing a reading device in the product movement line, and reading the barcode while the product is being moved.
Alternatively, there is a method in which a store clerk or the like holds a pen-type reader and moves it to read the barcode affixed to the product.

In these conventional methods, when reading a large number of the same products, it is necessary to repeat the same reading operation many times.

In addition, since there may be cases where reading cannot be performed normally, there is a drawback that it takes time to read all the items correctly.

OBJECTS OF THE INVENTION The purpose of the present invention is to eliminate the above-mentioned conventional problems, and to provide a parcode reading device that can easily read barcode symbols of a large number of identical products in a short time. The feature of the present invention is that a trap and a switch are provided in the reader to read the barcode symbols of a large number of the same products, and once the barcode symbol is read in the normal way, the product or products can be read manually by operating the switch. It can be easily read in a short time without moving the instrument.

EMBODIMENT OF THE INVENTION Below, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a pen-type reader section of a barcode reader according to an embodiment of the present invention, in which a salesperson or the like uses a pen-type reader to read a code symbol or information 2 printed on a sticker 1. 4 is manually scanned, and the pen-type reader is equipped with a switch in order to easily read a large amount of the same information in a short time.

FIG. 3 is a block diagram of a Nokuichi code reading device which is an embodiment of the present invention.

(1) When attempting to read a barcode symbol (information) using the barcode reading device of the present invention, the pen-type reader 4 scans the barcode symbol 2 printed on the recording medium 1.

The pen-type reader 4 irradiates the recording medium 1 with light from a light source 5 , converts the reflected light into an electrical signal by a photoelectric conversion circuit 6 , and supplies the electrical signal to a recognition circuit 7 .

The recognition circuit 7 recognizes the read information, and the recognition result is input to the control circuit 9 as barcode information. Control circuit 9
The information input to is stored at a predetermined address in the storage circuit 8.

Next, when reading the same barcode symbol as previously read, there is no need to manually scan the pen reader 4, but the switch 3 provided on the pen reader 4 is operated.

That is, when the switch 3 is operated, a switch signal is input to the switch control section 10. The switch control unit 10 counts the number of switch operations.

When reading of the same barcode symbol is completed in this manner, switch information (number of times) is input from the switch control section 10 to the control circuit 9.

The control circuit 9 calculates the above information and the information already stored in the storage circuit 8, and stores the result in another storage area.

As described above, according to the present invention, when reading the barcode symbols of a large number of the same products, it is only necessary to scan the pen-type reader only the first time, and then operate (for example, press) the same number of switches as the number of products. This greatly simplifies the reading operation and reduces the time required for reading.

Effects of the Invention Since the structure is as described above, the present invention can obtain the following effects.

1. Since the reader is equipped with a switch and requires no effort to operate the switch, many identical barcode symbols can be read easily and in a short time.
