Abstract

PURPOSE:To read even a commodity which can not be turned upside down by reading a bar code with the aid of the optical system of a case body with a translucent window facing upwards or the optical system of a hand scanner with the translucent window facing downwards. CONSTITUTION:The translucent window 2 attached with a glass plate is built on the upper surface of the case body 1, and a PLU key board 4 is held on a pillar 3 built at the side of the case body, and a holder 9 to hold the hand scanner 7 freely detachably in the state that its translucent window 8 is made to face downwards, is fixed on the side surface of the key board 4. Usually, the bar code 27 of the commodity 26 is read by the photoelectric converting part of the case body 1. At the case the commodity 26, the bar code label 27 of which can not be turned downwards, the bar code 27 of this commodity 26, as it faces upwards, is brought close to the translucent window 8 of the hand scanner 7, which read the contents of the bar code label 27.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a stationary scanner.

2. Description of the Related Art Conventionally, there has been a stationary scanner in which an optical system of a barcode scanner is provided inside a casing having a transparent window formed on the upper surface to read images such as barcodes displayed on products.

Problems to be Solved by the Invention On the other hand, the price of the product is often displayed on the top of the product along with the barcode label so that customers can easily see it, so the barcode label is placed at the bottom facing the translucent window. However, the packaging of perishable foods and the like often consists of a tray containing the contents wrapped in a transparent film, and when such products are turned upside down with the barcode label facing down, the contents can be read. This may cause the product value to decline.

If barcode labels are affixed to both the top and bottom of the product, the above-mentioned problems with reading operations can be resolved, but since two barcode labels must be issued, there is a problem of increased running costs.

Means to Solve the Problems A stationary case with a transparent window formed on the top surface and a barcode scanner optical system housed inside, and a stationary case with a transparent window formed on one end and a barcode scanner housed inside. A portable hand scanner housed therein is provided, and a holder is provided at the top of the housing to detachably hold the hand scanner with the light-transmitting window facing downward.

Therefore, if you place the barcode label displayed on the product face down and face the translucent window of a stationary housing, and have the optical system inside the housing read the image, with the barcode label facing down, there will be a problem. The product is placed facing the translucent window of the hand scanner with the barcode label facing upward, and the image is read by the hand scanner's optical system.

Example An embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a stationary case, on the upper surface of which is formed a transparent window 2 equipped with a glass plate, and a column 3 erected on the side.
A PLU keyboard 3 is rotatably held by a hinge 5, and a display 6 is fixed to the upper surface of the PLU keyboard 4. Reference numeral 7 denotes a portable hand scanner that can be held with one hand, and a transparent window 8 is formed at the end of a case 7a of the hand scanner 7. Further, a holder 9 is fixed to the side surface of the PLU keyboard 4 for detachably holding the hand scanner 7 with the transparent window 8 facing downward. This holder 9 is formed of an elastic plate material,
It has a U-shaped cross section so that the hand scanner 7 can be inserted and removed from the side.

As shown in FIG. 3, inside the stationary housing 1, there are a laser beam emitting section 10, a scanning section 11 that scans the beam from the laser beam emitting section 10, a laser beam receiving section 12, and a laser beam receiving section 12. A binarization circuit 13 connected to the laser beam receiver 12, a pattern detection unit 14 connected to the binarization circuit 13, a decoding unit 15 connected to the pattern detection unit 14, and a decoding unit 15 connected to the binarization circuit 12. An optical system 17 consisting of an interface circuit 16 connected to a host computer 18 is provided.

The case 7a of the hand scanner 7 also includes an L for illumination.
An ED 20a is built in, and an interrupt switch 2o is provided on the front surface. The case 7a of the hand scanner 7 also includes a COD image sensor 19.
and a binarization circuit 21 are provided, and this binarization circuit 21 is connected to a cable 23 and a connector 24.
．． 25 to the decoding unit 15.

In such a configuration, 1 usually includes a photoelectric conversion unit 1 in a housing 1.
2 reads the barcode 27 of the product 26. That is, when the barcode 27 is directed toward the transparent window 2, the barcode label 27 is irradiated with a scanning line emitted by the laser beam emitting section 10 and scanned by the scanning section 11, and this reflected light is received by the laser beam receiving section 12. , a binarization circuit 13 converts the output of this laser beam receiver 12 into a digital signal,
The pattern detection section 14 inputting this digital signal reads the contents of the barcode label 27. The output of the pattern detection section 14 is decoded by the decoding unit 15 and transferred to the host computer 18.

In the case of a product 26 whose barcode label 27 cannot be turned downward, the barcode label 27 of this product 26
The user approaches the transparent window 8 of the hand scanner 7 with the hand scanner facing upward, and turns on the interrupt switch 20 of the hand scanner 7. As a result, the COD image sensor 19 receives the reflected light from the barcode label 27 illuminated by the LED 20a, the binarization circuit 21 converts the barcode image into a digital signal, and this digital signal is decoded in the housing 1. Unit 15 decodes and host combination coater 18
Output to.

In this way, the optical system 1 of the housing 1 is adjusted depending on the type of product 26.
7 or the optical system 22 of the hand scanner 7 can read the contents of the barcode label 27. Therefore, it is possible to read the barcode label 27 without attaching it to both the top and bottom surfaces of the product 26.

In addition, when reading operations are performed continuously with the hand scanner 7, the product 26 is read by approaching the translucent window 8 of the hand scanner 7 held in the holder 9, or the product 26 is read by bringing the product 26 close to the transparent window 8 of the hand scanner 7 held in the holder 9. In the case of the product 26, any usage mode may be selected, such as removing the hand scanner 7 from the holder 9, holding it with one hand, and touching the product 26 for reading.

Note that if the first interrupt switch is a type that automatically interrupts at high speed, the second interrupt switch can be used as in the above embodiment.
The trouble of operating 0 can be eliminated.

Effects of the Invention Since the present invention is configured as described above, the optical system of the housing having an upwardly facing light-transmitting window or the optical system of the hand scanner having a downwardly facing light-transmitting window can be used to scan the bar depending on the type of product. It is possible to read the code, and therefore it has the effect of making it possible to read even products that cannot be reversed and preventing the contents of the package from collapsing.
