Data transmitting receiving system, data transmitting receiving method and commodity information processor

Abstract

The present invention provides a data transmission and reception system, a data transmission and reception method, and a commodity information processor capable of easily and safely transmitting and receiving data between a commodity information processor inside a store and a data processing device outside the store. In the data processing device 8 of the headquarters, the mail addresses of the electronic scales 2 installed in the store 1 are registered, and the required commodity unit price data are sent to each electronic scale 2 by email. The transmitted unit price data is stored in the supplier mail server 13 . On the other hand, the electronic scale 2 installed in the store 1 is connected to the Internet 6 through the line 5, and while receiving the unit price data from the supplier mail server 13, calculates the price of the product based on the received unit price data.

Description

technical field [0001] The invention relates to a data sending and receiving system including a commodity information processor, a data sending and receiving method and a commodity information processor. Background technique [0002] In recent years, supermarkets and other stores have used electronic scales to measure the weight of products, labeling machines (label printing devices) that print product prices on labels, and conversion measurements that can perform actuarial calculations such as money registration while measuring product weights. Product information processors such as electronic scales with money registration functions. For example, in an electronic scale, while calculating the product price based on the unit price information of the product, the sales results of the product can be aggregated based on the measurement data of the product. [0003] Japanese Unexamined Patent Publication No. 2000-251185 discloses a data transmission and reception method between...

Problems solved by technology

[0007] In addition, in the case of sending data from the device outside the store to the electronic scale device, although the device outside the store is connected to the electronic scale device in the store through the telephone line, for each electronic scale device, the connection-transmission process is repeated. - The operation of cutting off increases the burden on the equipment outside the store and takes time

[0008] On the other hand, in the case of sending data from the electronic scale device in the store to the device outside the store, the burden on the device outside the store is increased because it is necessary to process all requests from the electronic scale device
