Abstract

Abstract Disclosed is an electronic cash register comprising an input unit including numeric keys to enter the numerical information such as price and function keys to enter a variety of transaction information, an internal processing circuit to process the numerical information entered by the input unit, an output unit to deliver numerical information entered by the input unit or numerical information processed by the internal processing circuit, a first memory to store the cumulative total values of the numerical information occurring from various transactions, a drawer to keep and store the cash, which is opened by an open command signal sent from the internal processing circuit at the end of various transactions, a timer to start timing in response to the open command signal of the drawer and to stop the timing action in relation to the closing action of the drawer, and a second memory to store a time information corresponding to the measured period by the timer according to the timing action of the timer.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 166 words
An electronic cash register comprising: input means including numeric keys to enter the numerical information such as a price and function keys to enter a variety of transaction information; internal processing means to process the numerical information entered by said input means; output means to deliver numerical information entered by said input means or numerical information processed by said internal processing means: a first memory to store the cumulative total values of the numerical information occurring from various transactions; a drawer to keep and store the cash, which is opened by an open command signal sent from said internal processing means at the end of various transactions; timer means to start a timing action in response to said open command signal of the drawer and to stop said timing action in relation to the closing action of the drawer; and a second memory to store a time information corresponding to the measured period by said timer means according to the timing action of said timer means.
Claim 2
Dependent Claim 166 words
An electronic cash register comprising: input means including numeric keys to enter the numerical information such as a price and function keys to enter a variety of transaction information; internal processing means to process the numerical information entered by said input means; output means to deliver numerical information entered by said input means or numerical information processed by said internal processing means: a first memory to store the cumulative total values of the numerical information occurring from various transactions; a drawer to keep and store the cash, which is opened by an open command signal sent from said internal processing means at the end of various transactions; timer means to start a timing action in response to said open command signal of the drawer and to stop said timing action in relation to the closing action of the drawer; and a second memory to store a time information corresponding to the measured period by said timer means according to the timing action of said timer means.
Claim 3
Dependent Claim 169 words
An electronic cash register comprising: an input unit including numeric keys to enter numerical information such as prices and function keys to enter a variety of transaction information; an internal processing unit to calculate and transfer numerical information signals; a display unit and a printer to deliver the entered or internally processed numerical information; a first memory to store cumulative values of the numerical information appearing in a variety of transactions such as prices; a drawer to keep and store the cash, which is opened by an open command signal from said internal processing unit; a timer to start a timing action in response to said drawer open command signal and also to stop said timing action in relation to the closing action of the drawer; and a second memory to keep and store the information corresponding to the timed period of said timer sequentially to the end of the timing action of said timer and also to deliver the stored data at the printer when resetting or reading.
Claim 4
Dependent Claim 169 words
An electronic cash register comprising: an input unit including numeric keys to enter numerical information such as prices and function keys to enter a variety of transaction information; an internal processing unit to calculate and transfer numerical information signals; a display unit and a printer to deliver the entered or internally processed numerical information; a first memory to store cumulative values of the numerical information appearing in a variety of transactions such as prices; a drawer to keep and store the cash, which is opened by an open command signal from said internal processing unit; a timer to start a timing action in response to said drawer open command signal and also to stop said timing action in relation to the closing action of the drawer; and a second memory to keep and store the information corresponding to the timed period of said timer sequentially to the end of the timing action of said timer and also to deliver the stored data at the printer when resetting or reading.
Claim 5
Dependent Claim 178 words
An electronic cash register comprising: an input unit including numeric keys to enter numerical information such as prices and function keys to enter a variety of transaction information; an internal processing unit to calculate and transfer numerical information signals; a display unit and a printer to deliver the entered or internally processed numerical information; a first memory to store cumulative values of the numerical information appearing in a variety of transactions such as prices; a drawer to keep and store the cash, which is opened by an open command signal from said internal processing unit; a timer to start a timing action in response to said drawer open command signal and also to stop said timing action in relation to the closing action of the drawer; a counting circuit to count up every time said timer measures a desired period; and a count keeping memory to enter and store the count of said counting circuit at the end of the timing action of said timer and to deliver the stored data to said printer when resetting or reading.
Claim 6
Dependent Claim 178 words
An electronic cash register comprising: an input unit including numeric keys to enter numerical information such as prices and function keys to enter a variety of transaction information; an internal processing unit to calculate and transfer numerical information signals; a display unit and a printer to deliver the entered or internally processed numerical information; a first memory to store cumulative values of the numerical information appearing in a variety of transactions such as prices; a drawer to keep and store the cash, which is opened by an open command signal from said internal processing unit; a timer to start a timing action in response to said drawer open command signal and also to stop said timing action in relation to the closing action of the drawer; a counting circuit to count up every time said timer measures a desired period; and a count keeping memory to enter and store the count of said counting circuit at the end of the timing action of said timer and to deliver the stored data to said printer when resetting or reading.
