Japanese Patent Application Laid-Open No. 08-044951

  Both the product reading work by the dedicated operator and the product reading work by the customer are accompanied by the scanning work of taking out the product from the shopping basket placed on the shopping basket and reading it with the scanner of the accounting body. Is a burden on the body. In this product take-out operation, the burden on the body varies depending on the position of the product in the shopping basket. That is, the products in the shopping basket are widely distributed from a position close to the operator to a position far from the operator, and in particular, when a product at a distant position is taken out, the burden on the operator's waist is large. Of course, the height of the shopping basket is also a factor that affects the size of the burden on the operator, but generally there is variation in the height of the operator, and the height of the shopping basket is suitable for people of average height. It is prescribed as follows. However, the difference in the burden based on the position of the product in the shopping basket exists for people of any height, and it is inevitable that there is a burden on the product position for all people. It is.

  The present invention provides a shopping basket that holds the bottom surface of a shopping basket on an upper surface of a shopping basket provided adjacent to an accounting main body having a data reading function by a scanner so as to incline toward an operator standing in front of the accounting main body. A holding part was formed.

  The burden on the body when taking out the product from the shopping basket is the same for the operator even if the height of the operator is different, so there is no difference in the position of the product for the operator, and the burden of taking out the product from all areas of the shopping basket is eliminated. Since it can be made almost constant and there are no product positions where an excessive burden is imposed, the operation is relatively easy.

  An embodiment of the present invention will be described with reference to the drawings. This embodiment relates to a self-checkout system. First, the accounting body 1 is provided in the center. This accounting body 1 is provided with a settlement function unit 3 on a housing 2. That is, a coin change machine 4 and a bill change machine 5 are provided below the settlement function unit 3. A table 6 is provided above the coin change machine 4 and the bill change machine 5, and a scanner 7, a code number input machine 8, and a receipt printer 9 are provided above the table 6. A touch panel surface 10 and a card reader 11 are provided on the top, and a lamp 12 is provided at the center back. The scanner 7 is formed so as to be separable as a scanner block 13, and is disposed in the housing 2 so as to be covered with a cover or the like so that it can be taken out.

On the left side of the accounting main body 1, a shopping basket 14 is integrally provided.
The shopping basket 14 has a casing 15 fixed to the casing 2, and a measuring instrument 16 is provided in the casing 15. The weighing instrument 16 has a weighing pan 17 whose upper surface is inclined. On the upper surface of the weighing pan 17, a shopping basket holding portion 19 that is formed so as to be inclined toward the operator and holds the shopping basket 18 is formed. The shopping basket holding part 19 has an L-shaped convex part protruding in a bead shape. In practice, the shopping basket 18 that slides on the weighing pan 17 comes into contact. A step portion protruding in an L shape may be formed. And the shopping basket holding part 19 of the shopping basket stand 14 arranged on one side of the accounting main body 1 becomes higher from the corner on the accounting main body 1 side on the operator side toward the corner on the diagonal side. It is so inclined. Specifically, when the size of the bottom of the shopping basket 18, that is, the length of A-C is 40 cm and the length of B-C is 35 cm, the inclination of the shopping basket holding portion 19 is inclined to the shopping basket 18. The angle of the straight line connecting the corner C on the operator side to the diagonal corner A with respect to the horizontal plane is 38.682 ° to 48.590 ° (approximately 35 ° to 50 °). The angle of the straight line connecting the corner C on the operator side to the corner B along the operator side of the bottom surface with respect to the horizontal plane is 16.602 ° to 25.377 ° (approximately 15 ° to 26 °). The absolute value of such an angle varies depending on the shape and size of the shopping basket 18.

  Further, a mounting table 20 is provided on the right side of the accounting body 1. The mounting table 20 is separate from the accounting main body 1 and has an independent housing 21. Further, the mounting table 20 is provided with a measuring instrument 22 on the casing 21, which is different from the measuring instrument 16. The weighing pan 23 of the weighing instrument 22 is formed with a positioning portion 24 that determines the position of the shopping basket 18 or the like that protrudes into an L shape and puts products. A product placing table 26 is provided behind the measuring device 22 via a support column 25 rising upward.

  On the right side of the mounting table 20 thus formed, another mounting table 27 is provided. The mounting table 27 is provided with a product mounting table 29 held by a column 28. In front of the product placing table 29, two plastic bag hooks 31 for holding a single plastic bag 30 opened so as to store products are formed to protrude. At the center of these shopping bag hooks 31, a holding portion 32 for holding unused stacked shopping bag 30 is provided. The mounting table 27 is also provided with a measuring device 33 different from the measuring devices 16 and 22.

  In such a configuration, the shopping basket 14, the accounting body 1, the mounting table 20, and the mounting table 27 are arranged in order from the left to the right. And these shopping basket 14, the accounting main body 1, and the mounting table 20 are connected to a power source and a signal line by connecting electric wires (not shown).

  First, when a shopper performs a self-checkout operation, the shopper himself becomes an operator, and there are two modes of operation. In the first mode, a shopping basket 18 brought by a shopper is placed on the right table 20 of the accounting body 1 and the scanned product is placed in the shopping basket 18 when the accounting process is completed. The kite 18 is brought home as it is. The second mode uses the mounting table 27 provided with the plastic bag 30. When the scanned product is directly put into the plastic bag 30 and the accounting process is completed, the plastic bag 30 is left as it is. Take it home.

  Next, the case where the self-check is performed in the first mode will be described. First, the shopper places the shopping basket 18 containing the product to be purchased on the weighing pan 17 of the weighing instrument 16 of the shopping basket 14. At this time, the shopping basket holding unit 19 is placed in a state where the shopping basket 18 is inclined toward the operator, that is, the shopper, as described above. This state is that the shopping basket 18 is located at the correct weighing position, and there is no possibility that the weighing value will be distorted. When the shopping basket 18 rests on the weighing pan 17 in this way, the measured total weight is sent to the settlement function unit 3 as data. Then, the shopper scans the individual products with the scanner 7 in accordance with the screen instruction on the touch panel surface 10 of the accounting main body 1, and puts the finished product into the shopping basket 18 provided on the mounting table 20. When all the products are scanned and put into the shopping basket 18 on the right mounting table 20, the shopper performs accounting on the touch panel surface 10. In this accounting process, a cash or card payment method is selected by screen operation. In the case of cash, the cash is inserted into the coin changer 4 or the bill changer 5, and in the case of a card, the card is read into the card reader 11. Pass through. When such an accounting process is completed, a receipt is issued from the receipt printer 9. If there is a change, the change is returned from the coin change machine 4 or the bill change machine 5, and the checkout is completed. At this time, the total weight of the product including the shopping basket 18 measured by the measuring instrument 16 of the shopping basket 14 is measured, and the total weight after scanning all the products is measured by the measuring instrument 22 of the mounting table 20. It is weighed. Therefore, it is confirmed that all the registered products have moved to the shopping basket 18 by comparing the value obtained by subtracting the weight of the shopping basket 18 from the data of the measuring instrument 16 and the weight measured by the measuring instrument 22. This prevents fraud. The accounting body 1 is provided with a controller (POS), a power source, etc. (not shown) to control each device. In addition, although the weight of the shopping basket 18 that the shopper has brought is various, the weight before scanning and the weight after scanning are measured values of the change, so the absolute value of the shopping basket 18 The difference in weight is not a problem.

  Therefore, in the present embodiment, the shopping basket 18 is inclined toward the shopper by the shopping basket holding unit 19, and when viewed three-dimensionally, the product on the front side and the product on the back side of the shopping basket 18 There will be no large distance difference. The state of the burden on the body of the shopper's work at this time is confirmed by human simulation software Jack, and the results are shown in FIGS. 7 is a virtual human model of a tall person (95th percentile Japanese man, 179 cm tall), and the height of C on the bottom surface of the shopping basket 18 shown in FIG. When the height is 80 cm from the floor (+10 cm in comparison with C) and the height of A is 95 cm from the floor (+25 cm in comparison with C), the fourth and fifth postures of reaching out to each product This is an analysis of the force generated between the lumbar vertebrae. The analysis results show that A is 1451N (Newton), B is 1552N, and C is 1497N with respect to C as an example of a position where B is +10 cm and A is +25 cm. Therefore, the burden on the body is substantially the same regardless of the position at which the product is taken out from the bottom surface of the shopping basket 18.

  In addition, it can be seen in FIG. 7 that the height of the bottom of the shopping basket 18 from the floor surface is changed to 50 cm to 110 cm (C height) in a tall person, and the virtual human body model due to the difference in height is shown. Since the force generated between the fourth and fifth lumbar vertebrae has substantially the same inclination in each of A, B, and C, as described above, even if there is a difference in the height of the bottom surface of the shopping basket 18 from the floor surface, Even in the height, the force generated between the fourth and fifth lumbar vertebrae of the virtual human body model is substantially equal in each of A, B, and C, and an excessive burden is not applied.

  Next, FIG. 8 shows a state in which a virtual human body model of a short person (female 5th percentile, 155 cm) is used. When the height of B is +15 cm and the height of A is +30 cm with respect to the height of C on the bottom surface of the shopping basket 18 shown in FIG. 6, the force generated between the fourth and fifth lumbar vertebrae of the virtual human body model is , A, B, and C have substantially the same inclination, so that the burden on the body is substantially the same when the product is taken out from any position on the bottom surface of the shopping basket 18.

  In the implementation, since the height of the shopper varies, the absolute value of the height of the bottom surface of the shopping basket 18 from the floor should be determined eclectic to any height. That is, this embodiment is not intended to equalize the burden for people of different heights, but the absolute value of the burden differs depending on the height, but the product position differs for that person. The load is the same, and it is intended to average the burden on the body to eliminate an increase in the load depending on the position of the product. Therefore, since there is no place where the burden is locally large, the burden on the body is relatively reduced.

  The effect of reducing the burden on the body by inclining the bottom surface of the shopping basket 18 in this way is not only for the self-checkout system in which the shopper directly handles the product, but also when the dedicated operator performs accounting processing. The burden is reduced.

  Next, the self-check in the second aspect will be described. In this case, the product is moved by scanning the product taken out from the shopping basket 18 of the shopping basket 14 and directly putting the scanned product into the shopping bag 30 on the mounting table 27. Then, the weight of the product put in the shopping bag 30 is measured by the measuring instrument 34. At this time, a large number of shopping bags 30 are held on the mounting table 27, and the weight thereof changes according to the consumption of the shopping bags 30, but as described above, the weight of the product is measured as a change value. Therefore, even if there is an overall weight change of the shopping bag 30, there is no problem. The shopper brings home the shopping bag 30 filled with the products thus scanned.

1 shows an embodiment of the present invention and is a perspective view of the whole. FIG. It is the perspective view seen from the operator side of the state which put the shopping basket in the shopping basket holding part. It is a front view of a state where a shopping basket is placed in the shopping basket holding unit. It is a top view of the state which put the shopping basket in the shopping basket holding part. It is a side view of a state where a shopping basket is placed in the shopping basket holding unit. It is a top view which shows the position of the bottom face of a shopping basket. It is a graph which shows the change by the goods position of the state which considered that the tall person performed the relationship between the height from the floor surface of goods when taking out goods from a shopping basket, and a waist burden. It is a graph which shows the change by the goods position of the state which considered that the short person performed the relationship between the height from the floor surface of goods when taking out goods from a shopping basket, and a waist burden.
