Abstract
Abstract A data transmission device includes a memory for storing a plurality of data consisting of a plurality of sorting areas. The device selectively transmits the data of the sorting area including a desired data in response to a predetermined command signal. Data of the sorting areas including data not desired may not be sent. A central processing unit is connected to each of the electronic cash registers through one or more communication lines and when the electronic cash register receives a command signal sent from the central processing unit, the electronic cash register acts according to the command signal to send specific data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A method for selectively sending data from a host computer to a plurality of slave electronic cash registers operatively connected to a master electronic cash register comprising the steps of: (a) transmitting command signals from the host computer to a master electronic cash register for a slave electronic cash register operatively connected to said master electronic cash register, said command signals being signals for selectively retrieving specific sales data and/or all data in a divisional file of a memory in the slave electronic cash register, the division file including a plurality of sorting areas with some of said plurality of sorting areas, containing sales data while the remaining sorting areas contain other data; and (b) sending instructions from the master electronic cash register to the save electronic cash register based on the specific command signal.
Claim 2
Independent Claim
135 words
A method for selectively sending data from a host computer to a plurality of slave electronic cash registers operatively connected to a master electronic cash register comprising the steps of: (a) transmitting command signals from the host computer to a master electronic cash register for a slave electronic cash register operatively connected to said master electronic cash register, said command signals being signals for selectively retrieving specific sales data and/or all data in a divisional file of a memory in the slave electronic cash register, the division file including a plurality of sorting areas with some of said plurality of sorting areas, containing sales data while the remaining sorting areas contain other data; and (b) sending instructions from the master electronic cash register to the save electronic cash register based on the specific command signal.
Claim 3
Dependent Claim
64 words
The method of claim 1 further comprising the steps of: (c) processing the instructions in the slave unit based on the specific command signal, to select sales data and/or other data in the division file; (d) sending the selected data from step (c) to the master electronic cash register; and (e) forwarding the selected data from step (d) to the host computer for evaluation.
Claim 4
Independent Claim
187 words
A method for selectively controlling data sent from a plurality of electronic cash registers each of the electronic cash registers including a memory with a plurality of division files each division file including a plurality of sorting areas containing sales data and a plurality of sorting areas containing other specific data to be sent to a host computer unit so that unnecessary data is not sent back to the host computer comprising the steps of: (a) sending a signal from the host computer unit along at least one transmission line to each one of said plurality of electronic cash registers said signal identifying code data in at least one of said division files sorting areas containing said sales data; (b) selecting and receiving said signal in at least one of said plurality of electronic cash registers; (c) processing said signals in said at least one cash register so that only the specific selected sales data which is stored in the sorting area of the division files in at least one of said electronic cash registers is sent to said host computer based on said signal identifying code.
Claim 5
Independent Claim
187 words
A method for selectively controlling data sent from a plurality of electronic cash registers each of the electronic cash registers including a memory with a plurality of division files each division file including a plurality of sorting areas containing sales data and a plurality of sorting areas containing other specific data to be sent to a host computer unit so that unnecessary data is not sent back to the host computer comprising the steps of: (a) sending a signal from the host computer unit along at least one transmission line to each one of said plurality of electronic cash registers said signal identifying code data in at least one of said division files sorting areas containing said sales data; (b) selecting and receiving said signal in at least one of said plurality of electronic cash registers; (c) processing said signals in said at least one cash register so that only the specific selected sales data which is stored in the sorting area of the division files in at least one of said electronic cash registers is sent to said host computer based on said signal identifying code.
Claim 6
Dependent Claim
35 words
The method of claim 3 further including the step of sending a signal from separate devices operatively connected to each of the electronic cash registers to turn the operation of a electronic cash register on.
Claim 7
Dependent Claim
34 words
The method of claim 3 further including the step of sending a signal from separate devices operatively connected to each the electronic cash registers to turn the operation of the electronic cash register off.
