Abstract
Abstract A sales data transmission system includes a sales data processor such as a scale of the type capable of calculating and displaying a sales price from a unit price and a measured weight, a communication device which is made a part of this data processor and transmits and receives signals indicative of sales data and a memory unit which serves not only to receive and store the sales data transmitted from the communication device but also to transmit the stored sales data back to the communication device in response to a request signal therefrom.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A sales data transmission system comprising: a plurality of data processors for calculating and displaying a purchase price, each of said data processors having communication means for transmitting and receiving purchase data, and a wireless portable transceiver unit having memory means for storing data, said transceiver unit being capable of receiving and storing purchase data transmitted from and of transmitting purchase data stored in said memory means to one of said communication means within a communication range of said transceiver unit in response to a request signal from said one of said communication means.
Claim 2
Dependent Claim
94 words
A sales data transmission system comprising: a plurality of data processors for calculating and displaying a purchase price, each of said data processors having communication means for transmitting and receiving purchase data, and a wireless portable transceiver unit having memory means for storing data, said transceiver unit being capable of receiving and storing purchase data transmitted from and of transmitting purchase data stored in said memory means to one of said communication means within a communication range of said transceiver unit in response to a request signal from said one of said communication means.
Claim 3
Dependent Claim
34 words
The sales data transmission system of claim 1 wherein said data processors are scales capable of calculating a purchase price from a measured weight and a unit price and displaying said calculated purchase price.
Claim 4
Dependent Claim
15 words
The sales data transmission system of claim 1 wherein said data processors are cash registers.
Claim 5
Dependent Claim
24 words
The sales data transmission system of claim 1 wherein said communication means and said transceiver unit exchange said purchase data therebetween through wireless means.
Claim 6
Dependent Claim
34 words
The sales data transmission system of claim 1 wherein said transceiver unit exchanges data with said one of said communication means only in response to a signal from said one of said communication means.
Claim 7
Dependent Claim
64 words
The sales data transmission system of claim 1 wherein each of said data processors has a control device and an input device, said control device being so programmed as to cause a new purchase data item to be added to a total data item stored in said memory means of said transceiver unit in response to an add command received through said input means.
