Abstract

Point-of sale (POS) devices and checkout devices are provided. An exemplary checkout apparatus includes a plurality of sensing elements arranged in fixed relationship with each other at the mouth of a bag. At least one of the sensing elements senses a code arranged on a product as the product is being placed into the bag.

Claims

1. A point-of-sale (POS) device, comprising:

a platform;

a sensor assembly comprising a housing configured to at least partially wrap around a central space provided for a bag, the height of the housing being adjustable with respect to the platform; and

a plurality of sensing elements mounted about the housing, each of the sensing elements being configured to sense an identification code on a product within a field of view and a depth of field corresponding to such sensing element;

wherein the plurality of sensing elements are configured and arranged about the housing at various angles relative to the central space so as to provide a three-dimensional scanning space outside the mouth of the bag at least partially surrounded by the housing, the three-dimensional scanning space representing the cumulative fields of view and depths of field of the plurality of sensing elements; and

wherein each portion of the three-dimensional scanning space corresponds to the field of view of at least one of the plurality of sensing elements, such that as a product having an identification code thereon passes through the three-dimensional scanning space, at least one of the plurality of sensing elements will have a field of view capable of sensing the identification code when the identification code is in the three-dimensional scanning space as the product is being placed into the bag.

2. The POS device of claim 1, wherein the sensor assembly housing has an adjustable height configurable to position the three-dimensional scanning space outside the mouth of the bag.

3. The POS device of claim 1, wherein the height of the housing being adjustable allows the three-dimensional scanning space to be positioned outside the mouth of the bag when the bottom of the bag rests on the platform.

4. The POS device of claim 1, further comprising a support assembly coupled to the housing, the support assembly configured to position the three-dimensional scanning space at the mouth of the bag.

5. A checkout apparatus comprising:

a sensor assembly comprising a housing and a plurality of sensing elements configured and arranged about the housing so as to provide a three-dimensional scanning space at a location intended to be near the mouth of a bag, the three-dimensional scanning space representing the cumulative fields of view and depths of field of the plurality of sensing elements, the height of the housing being adjustable with respect to the location intended to be near the mouth of a bag;

wherein each portion of the three-dimensional scanning space corresponds to the field of view of at least one of the sensing elements, such that when an identification code on a product passes through the three-dimensional scanning space, at least one of the sensing elements will have a field of view enabling such sensing element to sense the identification code.

6. The checkout apparatus of claim 5, wherein the sensor assembly housing has an adjustable height configurable to position the three-dimensional scanning space outside the mouth of the bag.

7. The checkout apparatus of claim 6, wherein at least two of the plurality of sensing elements are oriented at different angles with respect to each other.

8. The checkout apparatus of claim 6, wherein at least one of the sensing elements is oriented at an angle with respect to an imaginary plane generally parallel with the mouth of the bag.

9. The checkout apparatus of claim 5, wherein the sensing elements are mounted on the housing.

10. The checkout apparatus of claim 9, wherein the housing at least partially surrounds the scanning space outside the mouth of the bag.

11. The checkout apparatus of claim 9, further comprising a support assembly coupled to the housing, the support assembly configured to position the sensor assembly near the mouth of the bag.

12. The checkout apparatus of claim 11, wherein the support assembly is configured to support the housing and a plurality of bags.

13. The checkout apparatus of claim 9, further comprising at least one light mounted on the housing, wherein the at least one light is configured to enhance the ability of the sensing elements to sense the identification code.

14. The checkout apparatus of claim 5, wherein the identification code comprises at least one of a barcode, a quick response (QR) code, and a data matrix code, and wherein the plurality of sensing elements comprises at least one of barcode readers, laser scanners, one-dimensional scanners, two-dimensional scanners, two-dimensional imagers, and linear imagers.

15. The checkout apparatus of claim 5, further comprising at least one indicator configured to indicate whether the identification code is successfully sensed when the identification code passes through the scanning space.

16. The checkout apparatus of claim 15, wherein the at least one indicator includes at least one of visual indicators and audio indicators.

17. The checkout apparatus of claim 15, further comprising a product-flow detector configured to detect when a product is being placed into the bag and/or when a product is being removed from the bag.

18. The checkout apparatus of claim 5, wherein each of the plurality of sensing elements has a depth of field sufficient to sense the identification code at a distance at least as great as a line-of-sight distance from the respective sensing element to a center point of the mouth of the bag.

19. A product-sensing device, comprising:

a sensor assembly having a plurality of sensors configured and arranged to provide a three-dimensional scanning space at least partially surrounded by the sensor assembly, the three-dimensional scanning space representing the cumulative fields of view and depths of field of the plurality of sensors;

wherein the sensor assembly comprises a housing having an adjustable height configurable to position the scanning space at a location intended to be near the mouth of a merchandise bag; and

wherein each portion of the three-dimensional scanning space corresponds to the field of view of at least one of the sensors, such that when a product having an identification code passes through the three-dimensional scanning space, at least one sensor includes a field of view capable of scanning the identification code.

20. The product-sensing device of claim 19, further comprising a support assembly coupled to the sensor assembly, the support assembly adjustable and configured to position the sensor assembly near the mouth of the merchandise bag.

21. The product-sensing device of claim 20, wherein the support assembly includes a platform and a scale formed in a top surface of the platform, the platform and scale configured to support and detect the weight of the merchandise bag and products in the merchandise bag.

22. The product-sensing device of claim 21, wherein the support assembly comprises a stand and at least one leg, the platform coupled to a top portion of the stand, the at least one leg extending upward from the platform and configured to support the sensor assembly.

23. The product-sensing device of claim 19, further comprising:

at least one illumination element mounted on the sensor assembly, the at least one illumination element being configured to enhance the ability of the sensors to sense the identification code; and

at least one indication element mounted on the sensor assembly, the at least one indication element being configured to indicate to a user whether the identification code associated with the product is successfully.

24. The product-sensing device of claim 19, wherein the identification code comprises at least one of a barcode, a quick response (QR) code, and a data matrix code, and wherein the plurality of sensors comprises at least one of barcode readers, laser scanners, one-dimensional scanners, two-dimensional scanners, two-dimensional imagers, and linear imagers.

25. The product-sensing device of claim 19, further comprising a product-flow detector configured to detect when a product is being placed into the bag and/or when a product is being removed from the bag.

26. The product-sensing device of claim 19, wherein each of the plurality of sensors has a depth of field sufficient to sense the identification code at a distance at least as great as a line-of-sight distance from the respective sensor to an approximate center point of the scanning space near the mouth of the merchandise bag.
