Definitions

  • the invention relates to a device for determining the selling price of goods, in particular goods offered in self-service sales outlets, which has the features of the preamble of claim 1.
  • the known devices of this type have readers for such goods, the packaging of which is provided with a map on which the price is given, for example in a bar code, for indicating the price on the map.
  • Such maps have the disadvantage that they usually have to be applied by the seller because of the prices to be set by the seller and if a price change it is necessary to overlap with a new map.
  • these known devices For goods that have to be weighed for price determination, these known devices have scales with a keypad, the keys of which are each assigned to a commodity, this assignment for the user by means of a suitable identification, for example a number, a letter or a combination of letters, in many cases also indicated by an illustration of the goods. The user must Select and press the corresponding button for the goods placed on the load plate from the keypad.
  • the electronics are supplied with the identification signal.
  • the electronics determine the sales price, which is printed out on an adhesive label or the like.
  • a disadvantage of these scales is not only that the labeling of the keys is subject to wear and tear and therefore the identification of the labeling can be difficult with frequent actuation, provided the keys are not formed by fields on a screen. In the latter case, if an image of the assigned goods is displayed in the fields, an image memory can be provided from which the required images can be called up. However, this has the disadvantage that the correct image may first have to be sought, which leads to annoying waiting times.
  • the invention has for its object to provide a device for determining the selling price of goods, which neither requires a map containing the price on the packaging or goods required nor a selection of buttons or fields to be made by the customer to identify the goods. This object is achieved by a device having the features of claim 1.
  • identification of each product is carried out by an automatic comparison of the product image generated by the video camera with the product images of the identifiable goods in the image memory, the customer's activity is limited to placing the product on the presentation area, to which the video camera is aimed. If the goods themselves are not suitable for providing the identification picture, you can add an identification sign or align it with the video camera so that it can recognize it.
  • identification marks include, for example, stickers for the goods or their packaging or also signs which are placed on the presentation area in addition to the goods. These identification signs can For example, be contained in a storage container, which is located in the associated goods. Even if such identification signs are required in exceptional cases, the time during which the presentation area is occupied is minimal.
  • the presentation area is advantageously formed by the load plate of a scale with a weight sensor, the output signals of which indicate the weight of the goods. The goods can then be identified during the weighing process.
  • At least each presentation area that receives the goods for a first-time identification is assigned an output device, preferably in the form of a display device, which announces the identified goods figuratively and / or in writing and / or acoustically.
  • the customer can then check whether the goods in question have been correctly identified.
  • each of these output devices preferably has an input device, for example in the form of a key or voice input, which the customer actuates or addresses if the goods identification was correct. If the identification is incorrect, the customer can be asked via the output device to move the goods to a different position.
  • an automatic change of position and / or the use of at least two video cameras capturing the image of the goods from different directions can also be used to improve the possibility of identification.
  • the output device also means for announcing the sales price of the goods and / or the sales price per unit of weight.
  • the output device therefore preferably has a screen on which the information to be disclosed to the customer appears.
  • audio output means can be provided, which deliver the information in acoustic form.
  • the information could also be output only acoustically. A printout of the information is also possible.
  • the issuing of a customer identification card to each customer offers special advantages, on which all relevant data is saved during each identification process.
  • a reader and writer is therefore advantageously assigned to each presentation area for the transfer of at least the sales price to the customer identity card.
  • customer identity cards With such customer identity cards, the recording of the goods and the determination of the total sales price at the checkout can be considerably accelerated, even if the data stored on the customer identity card is not used to determine the total price, but only for comparison with the other data recorded at the cash register can be used.
  • This data acquisition at the cash register is preferably also carried out with the aid of a video camera, an image memory, a comparator and, if appropriate, a weight sensor.
  • reading and writing devices assigned to the individual presentation areas for the customer identity cards are connected to a central computer, all of this data can be temporarily stored there, so that they then only need to be called up from the central computer when the customer is at Cashier is coming. Furthermore, readers can be provided with an output device that enable the customer to query information of interest to him at any time, in particular the total price of the goods selected so far.
  • An internally or externally arranged reading device is preferably provided for loading the image memory or the image memory, by means of which the images from data carriers on which the digitized identification images of all different goods are stored can be read into the memory.
  • the memory can then be loaded and updated in a particularly simple manner and above all without specialist knowledge.
  • the data carriers can, for example, be conventional disks with magnetic or optical storage of the digital signals.
  • An external arrangement of the reading device has the advantage over an internal arrangement that it can be used for several goods identification devices.
  • buttons for main goods groups, e.g. B. provide fruits, drinks, canned goods, vegetables, non-food.
  • the customer can then select the main product group to which the product to be identified belongs. It can be provided here that the identification only begins after the key or the like assigned to the main product group has been pressed by the customer.
  • the device shown in FIG. 1 for determining the selling price of goods offered in a self-service point of sale has any number of self-service scales 1, which are expediently set up wherever weight-dependent goods are offered.
  • One of these self-service scales 1 is also set up at each cash register 2. Since only one goods identification is required for weight-independent goods, detection devices 3 are set up wherever such goods are offered. Since the identification of goods independent of weight can also take place on the load plate of a self-service scale, there is generally no need to set up a recording device 3 at each checkout 2.
  • the use of a scale at the checkout to identify goods that are independent of weight even has the advantage that the weight is available as an additional feature for identification, for example for goods with a very similar appearance but different weights, which facilitates clear identification.
  • the device also includes any number of output devices 4 for customer identity cards 5 and read / write devices 6 for these customer identity cards 5.
  • the output of a customer identification card 5 can be made dependent on this that the customer has an authorization card, for example a check card 9, which he must first enter into the output device 4.
  • One of these read / write devices 6 is assigned to each self-service scale 1 and each detection device 3 in order to be able to write the data determined there into the customer identity card 5.
  • a reader 7 for reading the data stored on the customer identity cards 5 is provided at each cash register. In the exemplary embodiment, further reading devices 7 are installed in the sales room.
  • Each output device 4 and the reading devices 7 are also preferably connected to this master computer 8 via the data bus 10.
  • Each of the electronic self-service scales 1 has a load plate 11 on which the goods 12, which are, for example, a banana, are placed by the customer for the weighing process.
  • the weight is determined in a known manner by means of weighing electronics 13 contained in a weighing cell.
  • a video camera 14 is arranged which, as shown in FIG. 2, is rigidly connected to the scale housing 16 via a tripod 15 , of course, but could also be connected to the supporting surface 17 supporting the scales.
  • the video camera 14 can capture the entire goods support surface of the load plate 11.
  • the video camera 14 is followed by an amplifier-digitizer 18, which can also be built into the video camera 14 and digitize the image taken by the goods 12.

  • the final goods identification is essential accelerates.
  • an identification sign for example a sticker which is to be attached to the banana or which already exists and which bears an image or sign which unmistakably identifies the goods, could be used for the goods identification.
  • the digital image signals are fed to a comparator 19 used for image identification.
  • This is also connected to a memory 20, in which all recognizable identification images, ie the images of all recognizable goods or their identification symbols, are contained in digitized form.
  • the comparator 19 transmits the identification signal belonging to this product to the scale electronics 13.
  • This signal contains the information or is supplemented with the information about the price per unit weight of the recognized goods, which is generated in the known self-service scales by pressing the key assigned to the goods on the scale keyboard.
  • the price that can be calculated by the scale electronics 13 and paid for the goods 12 lying on the load plate 11 can be printed out on a data carrier, preferably in the form of an adhesive label, by means of a printer 21.
  • This data carrier which can also carry the name of the goods, their weight and the price per unit of weight, is then output, as is customary in the known self-service scales. If this data is written into the customer identity card 5, as is the case in the exemplary embodiment, the output of the data carriers could also be omitted.
  • the scale electronics 13 give the name of the goods 12, the price per unit of weight, their weight and the amount to be paid in the form of digital signals to control electronics 22, which is connected downstream of comparator 19 and controls a display device 23.
  • This display device 23 has a monitor on which the image of the goods 12 stored in the memory 20, for example as a color image, is reproduced for control purposes.
  • the information supplied by the scale electronics 13, ie the name of the goods, the price per unit of weight, the weight and the amount to be paid appear on the monitor.
  • the monitor of the display device 23 is held by a stand 23 provided next to the load plate 11 'approximately at eye level of the customer, so that the screen is in the customer's field of vision.
  • the display device 23 contains a loudspeaker 24 instead of or in addition to the monitor, which is preferably arranged within the balance housing 16, then the name of the goods 12, their price per unit weight and / or their weight and / or the amount to be paid can be acoustically displayed be, either once or several times with an adjustable volume and repetition rate.
  • each display device 23 is assigned an input device, for example in the form of a pushbutton or keyboard 30, so that the customer can confirm to the electronics that the goods identification and the data transaction carried out are correct. The confirmation could also be done acoustically. Speech recognition electronics are then required. If the goods identification and / or the data transaction is not correct, then the goods 12 must be moved to a different position in order to repeat the identification.
