Description

[Detailed description of the invention] The present invention relates to a barcode reading device that automatically reads optically readable barcode labels.
To provide a barcode reading device that allows smooth reading operations.

In conventional barcode reading devices equipped with optical reading means, the light beam is projected upward from the bottom. Since the position of the barcode label cannot be visually confirmed, it is difficult to properly align the barcode label with the light beam. As a result, the reading processing time per item was also slow. Furthermore, information written on the front side is usually used for classification after reading, and once the paper is turned over, the operator is forced to work very hard, which is a factor that impairs work efficiency.

The present invention aims to solve the conventional problems and improve work efficiency by projecting a light beam from above to below. In other words, the present invention provides a high value-added barcode reading device that enables smooth reading of barcode labels without turning them over, speeds up processing time, and improves the efficiency of sorting operations. This is what we provide.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a table, 2 is a support body attached to the upper rear part of the table 1, and a main body 3 is fixed onto this support body 2. In FIG. The front part of the main body 3 projects further forward than the front part of the support body 2, and a space is formed between the front projecting part of the main body 3 and the table 1. Reference numeral 4 denotes a panel provided at an angle on the front surface of the main body 3, and this panel 4 is provided with a display section 5 for displaying read information, etc., and a keyboard section 6 for inputting various information. 7 is a hood that covers the upper part of the display section 5;
is an L-shaped holding rod provided on the main body 3; 9 is a light pen; a connection line 10 connected to the light pen 9 is supported by the L-shaped holding rod 8; Reference numeral 11 denotes an optical scanning means disposed at the front inside the main body 3, and a light beam 12 emitted from the optical scanning means 11 is projected toward the table 1 through an outlet 13 provided on the bottom surface of the main body 3. Reference numeral 14 designates an anti-reflection area provided on the upper surface of the table 1 in a portion onto which the light beam 12 is projected, and 15 and 15' designate sensors for object detection provided on both sides of the anti-reflection area 14, respectively. Reference numeral 16 denotes an article to which a barcode label 17 shown in FIG. 12, the barcode is automatically read and displayed on the display section 5.

The configuration of the optical scanning means 11 built in the main body 3 is shown in Fig. 3. The light beam emitted from the light source 18 is deflected downward by the scanning system 19,
By scanning a bar code label 17 attached to an article 16, the reflected light 12' is converted into an electrical signal by a photoelectric converter 20, and the waveform-shaped signal is sent to a determination circuit 21, which reads the bar code.

FIG. 4 shows an example of a barcode reading operation in the device of the present invention. The operator holds the barcode label 17 or the article 16 to which the barcode label 17 is affixed in his/her hand 22 and scans the barcode on the label by passing the light beam 12 through the optical scanning area while checking the label position. is automatically read. Furthermore, the input information is displayed on the display section 5.

The sensors 15, 15' for detecting the article 1
Depending on whether sensor 6 is operated from right to left or from left to right, either sensor 15 or 15' is selected, and either sensor performs detection and a reading start signal is issued. Further, an anti-reflection area 14 provided to prevent light reflected from the table 1 is covered with a black matte thin film sheet to prevent light reflected from the table 1. FIG. 5 shows an anti-reflection means in another embodiment, in which a slit 23 is formed on the table 1 in accordance with the shape of the scanning pattern of the light beam 12.
The light beam 12 is configured to pass through the space of this slit 23 and exit downward, and no reflected light from the table 1 is generated.
Similar to the embodiment shown in FIG. 1, the reflected signal from the label is also stable, and an effect that does not dazzle the eyes can be obtained.

Furthermore, in the above embodiment, when the article 16 to which the barcode label 17 is attached cannot pass through the optical scanning area, or when the optical scanning means 11 becomes unusable, as an alternative, , a light pen 9 having the same function as the optical scanning means 11 is provided, and the light pen 9 can also read the bar code on the bar code label 17 and automatically input data.

The keyboard section 6 is used for setting the date, inputting the number of people, etc.
Furthermore, when both the optical scanning means 11 and the light pen 9 become unusable, it has a function that allows manual input while looking at the display section 5 as the last input means.

In this embodiment, reading can be performed while visually confirming the position of the barcode label with the barcode label facing up, eliminating the need for the operator to turn the barcode label over. , the barcode reading operation can be performed smoothly, improving work efficiency and speed, and is effective in improving work ability. Furthermore, it is a tabletop type in which the main body, table, and support are integrated, and has the advantage that the installation location can be easily changed and the installation direction can be easily changed depending on the work performance.

As is clear from the above embodiments, the present invention provides an anti-reflection area in the reading area that absorbs the light beam, provides object detection sensors on both sides of the anti-reflection area, and uses a light pen in addition to the optical scanning means. With this configuration, the reflected signal from the label is stable, the barcode can be read without dazzling the eyes, and the barcode can be reliably read even if the article is inserted into the optical scanning area from either the left or right direction. This has the effect that even large objects that cannot pass through the optical scanning area can be easily read with a light pen.
