Abstract

PURPOSE:To permit an operator to read a bar code without changing the direction and the top and bottom of a product with a single operation. CONSTITUTION:This stationary-type scanner 11 is irradiated with laser beams 7 and 8 from two directions. Then, a merchandise 10 is moved in the direction of an arrow A. The laser beam 7 reads the bar codes of the faces 4 and 5 of the merchandise 10 and the laser beam 8 reads the bar codes of the faces 1, 2 and 6 of the merchandise 10.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a stationary scanner.
In particular, it relates to a stationary scanner that reads barcodes while moving products.

0002

2. Description of the Related Art Conventional stationary scanners, as shown in FIGS.
To read the barcode displayed on the surface of 10,
The product 10 is moved in the direction of arrow B. At this time, a laser beam (indicated by a dotted arrow) 21 is irradiated from the reading window 22 of the stationary scanner 20, and the barcode is read by a reading mechanism (not shown). In this case, the barcodes on sides 4 and 5 of the barcode sides 1 to 6 of the product 10 are read.

0003

[Problems to be Solved by the Invention] Since the conventional stationary scanner described above uses one laser beam 21 for reading barcodes,
The barcode on the side cannot be read. Therefore,
When reading barcodes on these sides, there is a drawback in that the operator must change the orientation or top and bottom of the product 20 and read it again. In addition, if a product is sold at Tenji Muyo, such as a pre-assembled fresh pack, and a barcode is displayed on the top side, the barcode cannot be read and the barcode is placed on another side. The disadvantage is that the code must be displayed.

0004

[Means for Solving the Problems] The present invention is a stationary scanner that irradiates a barcode displayed on the surface of a product with a laser beam and reads it, characterized in that the laser beam irradiates from two directions. shall be.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an outline of an embodiment of the present invention. Reference numeral 11 denotes a stationary scanner of the present invention, which moves the product 10 in the direction of arrow A in order to read a barcode displayed on the surface of the product 10 (for example, a rectangular parallelepiped).

The stationary scanner 12 of the present invention is provided with reading windows on two sides for irradiating laser light, and as shown in FIG. 1, the reading windows 9a and 9b are arranged at right angles. Then, laser beams 7 and 8 are irradiated from these reading windows, respectively, and the barcode is read in the same manner as in the conventional example.

In this embodiment, the product 1 is
The barcodes on the 4th and 5th sides of 0 are read, and the barcodes on the 1st, 2nd and 6th sides are read with the laser beam 8. In other words, barcodes on surfaces other than side 3 of the product 10 are read in one operation.

[0009]

[Effects of the Invention] As explained above, since the stationary scanner of the present invention emits laser light from two directions, the operator does not have to change the orientation or the top or bottom of the product with a single operation.
It has the effect of being able to read barcodes on five sides of a product while being easy to hold.
