Abstract

An improved price updating apparatus for use in retail store pricing systems has an input for receiving update data indicative of a product for which a price change is desired and the changed price. The apparatus looks up records in a database relating to store locations, for locations where the product may be found. Where the location has an electronic price display device, preferably connected with the apparatus by a serial data link, the changed price is transmitted to the display device by the serial data link. Where the location has a printed price, the apparatus stores a print job record containing information about the price and the shape and size of printed price. A user is later able to select, one by one, the various shapes and sizes of printed prices, and to print all the records intended for printing at the selected shape and size.

Claims

1. Price updating means for use in a price display system including both individually addressable information display devices and printed price indicators disposed to display prices, and having a data source, a communications channel connecting said data source with said information display devices, and a printer connected to the data source, said printer disposed to print said printed price indicators in response to print commands, the data source comprising a first data file of records corresponding to product locations, each record containing product information indicative of the product associated with the location corresponding thereto, each record also containing information indicative of whether the location corresponding thereto is associated with an information display device or with a printed price indicator, the price updating means comprising:

input means for receiving update data indicative of a product for which a price change is desired and the changed price therefor;

lookup means responsive to the update data for looking up among records in the first data file those matching records, if any, for which the product information matches the product for which a price change is desired;

first posting means responsive to a matching record having information indicative of its respective location being associated with an information display device, for posting the changed price to the associated information display device;

queueing means responsive to a matching record having information of its respective location being associated with a printed price indicator, for storing a print command capable of causing the printer to print a printed price indicator illustrative of the changed price; and

means responsive to said stored print command to activate said printer to print the price indicator.

2. The price updating means of claim 1, wherein the data source further comprises a second data file of records corresponding to products, each record containing product information indicative of the corresponding product, and price information indicative of the price associated with the product corresponding thereto, the price updating means further comprising:

second posting means responsive to the update data for locating the record, if any, for which the corresponding product matches the product for which a price change is desired, and for posting to the record the changed price.

3. The price updating means of claim 2 wherein the electronic price display devices of the price display system are mounted in housings adapted to receive respective printed overlays, each of which includes at least a portion of the related product information in said second data file, said price updating means further comprising:

means responsive to selection of a record in said second data file to activate said printer to print a label including said portion of the related product information.

4. The price updating means of claim 3 wherein said information display devices are mounted in housings of a plurality of different sizes and shapes and wherein said second data file includes data specifying the size and shape of the housing associated with each product, whereby upon activation, said printer prints labels of size and shapes corresponding to the respective display device housings.

5. The price updating means of claim 1, wherein the printed price indicators are of a plurality of sizes, and each record in the first data file associated with a printed price indicator further comprising information indicative of the size of the associated printed price indicator, the queueing means of the price updating means further comprising:

means responsive to a matching record having information of its respective location being associated with a printed price indicator, for storing in the print command information indicative of the size of the associated printed price indicator,

and means responsive to selection by a user of a size of printed price indicator for providing to the printer print commands for which the information indicative of the size of the associated printed price indicator matches a the selected size.

6. The price updating means of claim 1 wherein the printer of the price display system is a laser printer.
