Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a price checker, in particular to an immovable price checker with an angle-adjustable scanner.

2. Description of Prior Art

With the advancement of science and technology, barcodes are widely used in various articles. The barcodes provided on the article have important information (such as: price) of the article. Thus, in order to scan the barcodes on the article to check its price, various scanners are proposed. The scanner is combined with an external or built-in display to form a so-called price checker, whereby the price of the article can be displayed conveniently for customers.

The price checkers are classified into two categories including a movable price checker and an immovable price checker. The movable price checker is one which an operator can hold it by a hand and carry it to approach the article to scan the barcodes on the article. Such a movable price checker is often used on a cash counter in a convenience store. With an external display (such as a screen of a cash register) being electrically connected to the movable price checker, the information in the barcodes scanned by the scanner can be displayed on the display immediately.

Unlike the movable price checker, the immovable price checker is often fixed to a predetermined position (for example, fixed on a wall with approximately one meter from the ground). The immovable price checker is often used in a large-size supermarket. A customer has to move the desired article to the underside of the immovable price checker and then to rotate the article until the barcodes on the article are accurately scanned by a scanner provided in the immovable price checker. In this way, the information in the barcodes can be displayed on a screen built in the immovable price checker.

However, the customer may sometimes require strenuous effect to move a bulk and heavy article (such as a bag of rice) to the underside of the immovable price checker, and then rotate the article to make the barcodes on the article to be scanned by the scanner. Thus, the customer has to perform the above-mentioned steps in order to check the price of the article, which is so inconvenient and laborious for the customer.

U.S. Pat. No. 6,062,477 discloses a retail terminal 10 connected to a pivoting base assembly 18 with a tilt mechanism 56 and a stationary base 58 so that the retail terminal 10 is rotatable with respect to the stationary base 58 through the tilt mechanism 56. A scanner unit 80 can be connected to the retail terminal 10 through one connector 32 of the retail terminal 10 through a cable 102. The retail terminal 10 can be connected to a fixed-angle base assembly 246 in lieu of the pivoting base assembly 18 and the scanner unit 80 is installed to a housing 272 of the fixed-angle base assembly 246. However, the scanner unit 80 still cannot be rotated for scanning the barcodes on the article.

U.S. Pat. No. 5,478,998 discloses a tilting wall-mounted optical scanner 10 including a molded-plastic base member 12 installed on a vertical wall 13, and an optical scanning unit 14 connected to the base member 12 by means of pivot structure 16. However, the optical scanning unit 14 is not installed to any device.

Therefore, in order to solve the above-mentioned problems, the present Inventor proposes a novel and reasonable structure based on his research and experiments.

DETAILED DESCRIPTION OF THE INVENTION

The detailed description and technical contents of the present invention will become apparent with the following detailed description accompanied with related drawings. It is noteworthy to point out that the drawings is provided for the illustration purpose only, but not intended for limiting the scope of the present invention.

Please refer to FIGS. 1 to 4. The present invention provides an immovable price checker 1 with an angle-adjustment scanner (referred to as “price checker 1” hereinafter). The price checker 1 is installed on a wall (not shown) for scanning barcodes of an article (not shown). The price checker 1 includes a base 10, a scanner 20, a processor 30, a display 40 and a pivoting means 50.

The base 10 is substantially formed into a rectangular shape and fixed on the wall. As shown in FIG. 3, the bottom surface of the base 10 is provided with a plurality of fixing holes 11 for allowing hooks or nails (not shown) protruding from the wall to be inserted into the fixing holes 11. In this way, the price checker 1 can be fixed on the wall. The shape of the base 10 is not limited to the rectangular shape only, and it may be modified according to practical demands.

In the embodiment shown in FIG. 1, the scanner 20 is connected to a lower portion of the base 10 for scanning the barcodes of the article. The scanner 10 is substantially formed into an oval shape, and the interior of the scanner 30 is provided with a light source (not shown) for emitting light beams for scanning the barcodes. Since the components within the scanner 20 are not the technical characteristics of the present invention, the description relating thereto is omitted for simplicity. It should be noted that, since the light source is provided within the scanner 20 for emitting lights, the light source inevitably generates heat during its operation. In view of this, a portion of the surface of the base 10 adjacent to the scanner 20 is provided with a plurality of heat-dissipating holes 12, thereby dissipating the heat of the scanner 20 to the outside.

The processor 30 is provided in the base 10 and electrically connected to the scanner 20. The scanner 30 comprises a circuit board 31 and an input/output end 32 (FIG. 2, refereed to as “I/O end” hereinafter) provided on the circuit board 31. The interior of the circuit board 31 is provided with electronic circuitry (not shown) for processing the information of barcodes scanned by the scanner 20 and converting the information into the data to be displayed on the display 40. The I/O end 32 comprises various connecting ports 321 including USB, RJ-45, VGA or the like and a power input port 322. The connecting port 321 is electrically connected to a data processing system (not shown). The data processing system is configured to store the information of various barcodes and feedback the information of barcodes to the display 40. The bottom surface of the base 10 is provided with an accommodating trough 13 (FIG. 3), and the I/O end 32 is mounted in the base 10 with the connecting port 321 being observable in the accommodating trough 13. By this arrangement, it is convenient for the user to insert the connecting line (not shown) into the connecting port 321.

The display 40 is fixed to an upper portion of the base 10 and electrically connected to the processor 30 for displaying the data (such as the price of the article) processed by the processor 30. The display 40 comprises a screen 41 and a circuit board 42 electrically connected to the screen 41 and the processor 30. The user only needs to look at the data displayed on the screen 41 so as to know the price of the article.

The pivoting means 50 is connected between the base 10 and the scanner 20. In the embodiment shown in FIG. 1, the pivoting means 50 comprises a first engagement unit such as a hole 51 provided in the base 10 and a second engagement unit such as a pivot shaft 52 connected to one side of the scanner 20 to insert into the hole 51. By this arrangement, the scanner 20 is rotatable with respect to the base 10 to adjust the angle of the scanner 20 by using the pivot shaft 52 of the pivoting means 50 as a center of rotation.

According to the present invention, the angle of the scanner 20 can be adjusted in a stageless or multiple-stage manner. FIG. 5 shows the angle of the scanner 20 is adjusted in a stageless manner. When the hole 51 and the pivot shaft 52 are in an interference fit, the user can rotate (clockwise or counterclockwise shown in FIG. 5) the scanner 20 with respect to the base 10 around the pivot shaft 52 to a desired angle. The scanner 20 can be fixed to the desired angle by means of the friction force between the hole 51 and the pivot shaft 52. Thus, the scanner 20 is ready to scan the barcodes of the articles.

Please refer to FIGS. 6 and 7. In the present embodiment, the angle of the scanner 20 is adjusted in a multiple-stage manner. The pivot shaft 52 is not integrally formed with the scanner 20 but formed as a separate component. The periphery of the pivot shaft 52 is formed with a positioning flange 521. The positioning flange 521 is provided with a plurality of positioning holes 522 (seven shown in the FIG. 7). One surface of the scanner 20 adjacent to the positioning flange 521 is provided with a notch 21, in which a positioning post 22 and a spring 23 for abutting the positioning post 22 are provided. The positioning post 22 can be selectively engaged in one of the positioning holes 522. It can be seen from FIG. 6 that the tip of the positioning post 22 is made round to be easily engaged within the positioning hole 522. When the user exerts a force to rotate the scanner 20, the positioning post 22 can be removed from the original positioning hole 522 and engaged in another positioning hole 522, thereby achieving the multiple-stage adjustment of the angle of the scanner 20.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. The scanner 20 and the display 40 may not be necessarily provided in a vertical direction of the base 10. Alternatively, the scanner 20 and the display 40 may be provided in a horizontal direction of the base 10 as long as the scanner 20 can rotate with respect to the base 10. The shapes and dimensions of the base 10, the scanner 20 and the display 40 can be modified according to practical demands. In the previous embodiments of the present invention, although one side of the scanner 20 is connected to the pivot shaft 52, both sides of the scanner 20 may be provided with a pivot shaft 52 respectively to be connected to the base 10. The above modifications and equivalent changes are still embraced in the scope of the present invention.

In comparison with prior art, the present invention has advantageous effects as follows.

Since the scanner 20 is pivotally connected to the base 10 and rotatable with respect to the base 10 by using the pivoting means 50 as a center of rotation, the user can adjust the angle of the scanner 20 with respect to the base 10, so that the scanner 20 can scan the barcodes on the article easily. Thus, it is unnecessary for the user to laboriously rotate the article to make the barcodes to be scanned by the scanner of a conventional immovable price checker. Therefore, the convenience and practicability of the present invention are improved greatly.
