Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register having the function of recording the progress of commercial transactions.

Generally, an electronic cash register is provided with a printing section, and the progress of each commercial transaction is printed out sequentially as a business record. At this time, in order to save recording paper or shorten printing time (shortening mode), the price of each item is classified, organized and stored in the memory inside the electronic register, and the total for each category is calculated as necessary. In most cases, the process of registering each product is omitted, and a printed record like the one shown in Figure 4 is issued. Regarding important items, it is desirable to print them as exception items even in the above-mentioned omission mode in order to prevent operator fraud. However, until now, there has been no electronic register that has such a function and has a simple configuration.

The present invention seeks to provide an electronic cash register which eliminates the above-mentioned conventional drawbacks, and which includes:
The present invention will be explained below along with one embodiment thereof.

In Figure 1, 1 is a numeric key (NK) for entering the product amount, etc., 2 is a function key (FK) for selecting functions such as registering, correcting, and totaling the amount, and 3 is a flip-flop (FF). ), set terminal S20, output terminal O21, reset terminal R2
It has 2. 4 is a numeric register, and 5 and 8 are AND circuits. 6 is an arithmetic circuit which includes an adder/subtractor, a data determination circuit, a data transfer circuit, an input/output signal control circuit, and an output register, and includes a function information input terminal 23, a numeric input terminal 24, and a data output terminal 25. , total signal output terminal 26, sine signal output terminal 27, reset signal output terminal 29
has. 7 and 11 are OR circuits, 9 is a memory, and 10 is a printing section having a printing signal input terminal 30. Further, 28 is one input terminal of the OR circuit 11, to which a gate signal P is applied as described later.

Next, the operation of the above embodiment will be explained. Number key 1
By manipulating , the product amount and the like are input to the number register 4, and a signal is applied to the flip-flop 3 via the set terminal 20 to set it. Further, when the flip-flop 3 is set, the gate 5 is opened, and the operation input of the function key 2 is inputted to the arithmetic circuit 6 via the input terminal 23. The arithmetic circuit 6 has a number register 4
The data is organized and categorized using the number data from and the function data from the input terminal 23, and the contents of an output register (not shown) are transferred from the output terminal 25 to the memory 9. At the same time, the contents of the data output registers are outputted from the total signal output terminal 26 and the sine signal output terminal 27 as described later, and a reset signal is sent from the reset terminal 29 to reset the flip-flop 3.

The input terminal 28 of the OR circuit 11 receives a signal P, which is an output signal of the printing mode selection switch, when P=1 is inputted when all single item prices are to be printed, and when only specific data is to be printed, P=0 is inputted. Said P=
In the case of 1, the AND gate 8 is always open and a business record with all data printed is obtained as shown in FIG. On the other hand, when P=0, the AND gate 8 is opened by the OR gates 7 and 11 and printing is performed only when either the total signal or the sign signal is 1.

Next, the relationship between key operations and printing according to the above configuration will be explained using specific numerical examples. Now, when the key operations shown in FIG. 2 are used, the contents of the data output register of the arithmetic circuit 6 change in accordance with the order shown in FIG. In the figure, a is the amount digit indicating the contents of the register 4 or the output register, b is "0" indicating a positive sign when the registration of the single item amount is paid to the operator from the purchaser of the product, and In the case of a return from the operator to the purchaser (return), A, B, and C are code digits in which "8" is written as a substitute for a negative sign, and c is a department digit that indicates a numerical value coded for the department corresponding to the content of the product. , d represents a function digit in which a number corresponding to the code of a function key such as payment, correction, etc. is written, and e represents a total symbol digit in which 1 indicating a total is written.

As is clear from the above explanation, the sine signal output terminal 26 corresponds to the third bit of "8" in symbol digit b of the output register, and the sine signal output terminal 26 corresponds to "1" in digit e of the total symbol. "1" is output from each signal output terminal 27. Therefore, when the print mode switch is OFF and the mode is omitted printing, the input to the terminal 28 is "P=0", so in the contents of the output register shown in FIG. and the digit of the total sign “e=
1'' data, that is, only the d, ho, he, and g of FIG.
It will be printed as shown in Figure 5.

That is, in the embodiment described above, the content of each individual item amount input using the numeric key 1 is assigned a positive or negative sign from the viewpoint of deposit or payment, and by providing a means for determining the positive or negative sign, the printing unit 10 It is possible to control the distribution of data to transmission and stop.

In addition, in FIGS. 3 to 5, 0125 written at the bottom is an identification number for each transaction, and A is an operator name.

As is clear from the above embodiments, when it is desired to print out the total amount of returned goods, amount corrections, discounts, etc. among the results calculated by the arithmetic circuit, the present invention can be easily printed by selecting the print mode selection switch terminal. It has the effect of being able to.
