Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to improvements in cash registers and similar registers.

Prior Art In the print data of the inspection/settlement sheet issued from the conventional electronic cash register, all department data is printed, and even if the sales of a certain department is "0", it is printed. (Figure 1a) Recently, as shown in Figure 1b, this sales has decreased to "0".
An idea has been proposed to delete the printout from the inspection/settlement sheet for only those departments.

Problems to be Solved by the Invention However, even with this method, the departments where sales are "0" are not fixed, so when comparing with the previously printed checklist or multiple cash registers, it is difficult to determine the printing order. Since the values were not constant, it was difficult and inconvenient to compare them with each other.

On the other hand, with this type of register, from the standpoint of checking for incorrect data input, for example, if the unit price of products handled in a certain department is less than 10,000, the input data is limited to 4 digits, and the 5-digit data is A digit restriction method has been proposed that issues an alert as an incorrect input if there is an input. In such a case, the digit limit is set to "0" for departments that do not handle products.

This invention was made in order to eliminate the above-mentioned drawbacks of conventional cash registers, and when the above-mentioned digit limit is "0", it prevents printing of the data of that department on checklists, etc. The object of the present invention is to provide a register that can print receipts and journals that are easy to inspect and settle, while improving printing efficiency.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides an electronic cash register in which various transaction information can be registered and the number of input digits of input information such as departments for this registration process can be limited. It stores digit restriction information for each department, stores digit restriction information corresponding to the department for a department that handles products, and stores specific data (digit restriction information) for a department that does not handle products. 0), a check circuit for the digit limit memory that reads the contents of the memory and determines whether the digit limit information contains specific data (0), and a check circuit for each department during inspection and payment. a control device that outputs a printing permission signal to a printing device for a department other than the department in which specific data (0) of the digit restriction information in the digit restriction memory is detected by the check circuit when printing the transaction information; It is characterized by having the following.

Operation When a check command is issued, the check circuit reads the digit restriction information stored in the memory corresponding to each department and determines whether or not the digit restriction information contains specific data. Then, when the specific data is not detected, the control device outputs a print permission signal to the printing device. When the specific data is detected, the control device does not output a print permission signal, so no inspection data is printed for that specific department.

Note that although the following embodiments will be described with reference to a cash register, the present invention can also be applied to other data processing devices such as registers.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 2, numeral 1 indicates the keyboard of the electronic cash register, and this keyboard 1 has numerical keys 1 consisting of a numeric keypad for inputting numerical values from ``0'' to ``9'', and data representing the department to which the handled products, etc. belong. Multiple department keys 1 to enter separately
b, and an inspection instruction key 1c.

Reference numeral 2 designates a mode switch provided on the operation surface of the register, which is provided with various keys similar to known registers, but in this embodiment, a setting key 2a, a registration key 2b, and an inspection key 2c are shown. .

3 is a CPU using a microprocessor etc., 4
5 is a ROM in which a program to control the register is written, and 5 is a memory such as a RAM that stores input data, fixed data, etc.
is provided with areas 5a to 5f for storing digit limit values assigned to each department. In the illustrated embodiment, the first division is 4 digits, the second division is 4 digits,
The fifth division is 5 digits, and the third, fifth, and sixth divisions each have a digit restriction attached to 0.

The address of the memory 5 is specified by an address counter 9a controlled by data sent from the CPU 3, and the address is specified by an address counter 9a controlled by data sent from the CPU 3.
In addition to inputting data from the memory 5, the data is also read from the memory 5 via the output control circuit 9c.

Reference numeral 6 denotes a display section, and 7 a printing section, each of which displays data read out by the CPU or prints it out in a receipt or journal format. 8 is a buffer for temporarily storing print data.

Reference numeral 10 denotes a digit number check circuit which checks whether data such as the sales amount of products belonging to a certain department, which is input from the keyboard 1, is within the digit limit range assigned to that department. This digit number check circuit 10 receives input data such as sales amount and department from the keyboard 1 via a buffer 12, while information indicating that a department key has been operated from the keyboard 1 is applied via an AND gate 11. A signal is applied, and the digit limit value of the relevant department is applied from the memory 5. If the input data is within a predetermined number of digits, the input data is transferred to the CPU 3, and the input data is If is greater than the predetermined digit limit value, alarm circuit 1
3, a speaker 14 issues a warning that the input data is incorrect.

Reference numeral 15 designates an AND gate, which inputs signals from the setting key 2a and department key 1b, and its output is applied to the input control circuit 9b of the memory 5. , the input control circuit 9b is operated.

Numeral 17 is a digit limit memory check circuit that checks whether the digit limit value of the corresponding department of the read amount data is "0" at the time of inspection, payment, etc.; Data representing the department is applied from the buffer 8 and the digit limit value of the department is applied from the memory 5. If the digit limit value of the department is not 0, a high level or "1" signal is applied from the terminal 17b to the AND gate 18. , a print permission signal is applied to the printing unit 7 via the OR gate 19, while if the digit limit value is 0, the AND gate 18 is closed and printing of data for that department is prohibited.

A signal is applied to the AND gate 18 from the inspection key 2c.

Reference numeral 20 denotes an inverter, which generates a "1" signal when the check key 2c is in the off state, and provides a print permission signal to the printing section 7 via the OR gate 19.

When using the electronic cash register shown in the above embodiment, first, digit restriction information for each department is set according to the flowchart shown in FIG.

In other words, first press setting key 2 of mode switch 2.
Press a to turn on the AND gate 15 to enable operation, and then input digit restriction information to the CPU 3 using the numerical keys 1a of the keyboard 1. Next, in order to specify which department this digit restriction information corresponds to, the operator presses the department key 1b for the department to be specified on the keyboard 1, and presses the AND gate 1.
5, the input control circuit 9b of the memory 5 is enabled for operation, and the CPU 3 specifies an address for the department via the address counter 9a.

For example, if the amount handled by the first department is 9999 yen or less, the digit limit value "4" is input using the numerical key 1a, and the code indicating the first department is input using the department key 1b. The digit restriction information thus input to the CPU 3 is stored in any of the predetermined areas 5a, 5b, 5c, . . . of the memory 5 via the input control circuit 9b.

Such operations are performed for all departments to set digit restriction information for each department. Now, suppose the digit limit is 4 digits for the 1st and 2nd divisions, 5 digits for the 4th division, and the 3rd,
For departments 5 and 6, the digit limit is "0".

When the setting of all digit restriction information is completed as described above, the operator releases the setting key 2a of the mode switch 2 and presses the registration key 2b of the mode switch 2 to prepare for the next registration operation. When the registration key 2b is pressed, the AND gate 11 becomes operable.

When the operator sets the device in such a state and inputs numerical information (for example, amount information) for the transaction using the numerical keys 1a of the keyboard 1 in order to register a normal transaction, that information is input to the CPU 3 and is also sent to the buffer. 12 is also input and stored. Next, when the operator presses the appropriate key of the department key 1b to indicate which department information this numerical information corresponds to, this department information is input to the CPU 3 and passed through the AND gate 11 to the digit number check circuit 10. make it work.

Then, the address counter 9a operates according to the department information input as described above, specifies the address corresponding to this department in the memory 5, and displays the digit restriction information of that department, for example, a numerical value for the first department. "4" is read out from the memory 5 via the output control circuit 9c, and this digit limit information is applied to the digit number check circuit 10.

Then, based on this digit limit information, it is checked whether the number of digits of the numerical information that has just been input is within the digit limit, and if it exceeds the digit limit, the user is prompted to re-enter the input information. alarm circuit 13
An alarm is emitted from the speaker 14 via.

On the other hand, if the input numerical information is within the digit limit, the numerical information is written into the memory corresponding to the department and the contents are printed on the receipt by the printing unit 7. Further, each piece of information at this time is also displayed on the display section 6.

The above is a transaction processing operation for one product, but the operator performs this operation for all trading products, and when the registration process is completed, operates the transaction end key (not shown) to check the transaction total. The amount is added and stored in a predetermined area of the memory 5 for storing the daily cumulative transaction amount, a receipt is issued from the printing section 7, and the transaction processing for one customer is completed. (5th
(Figure) When the operator performs each transaction registration process in this manner and wishes to check the sales status at a certain point in time, the operator releases the registration key 2b of the mode switch 2 and presses the check key 2c.
When the inspection key 2c is pressed, the AND gate 18 becomes operable.

Next, when the operator presses the inspection instruction key 1c to turn it on, the CPU 3 outputs each information stored in the memory 5 to the buffer 8 via the output control circuit 9c.
Read out.

Now, for example, when the sales amount information regarding the first department is being read out, the digit limit information "4" in the memory 5a corresponding to the first department is also read out to the digit limit memory check circuit via the output control circuit 9c. 1
7, and it is checked whether the digit restriction information is "0" or not. In this case, the digit limit information is not "0", so terminal 1 of the digit limit memory check circuit 17
The output of 7b becomes "1", and the AND gate 18,
The printing permission signal is sent to the printing unit 7 via the OR gate 19.
is applied to Then, the sales amount of the first division applied from the buffer 8 is printed on the checklist as shown in the first line of FIG. 3a. The data is also displayed on the display section 6. A signal is applied from the memory check circuit 17 to the CPU 3, and the CPU 3 increments the address counter 9a to read out the information of the second division. The same operation follows. (FIG. 6) On the other hand, when the sales amount of the third division is now read out from the memory 5, the digit restriction information "0" of the third division is applied to the digit restriction memory check circuit 17. When it is determined that the digit limit of the third division is "0", the output of the terminal 17b of the check circuit 17 becomes "0", and the AND gate 1
8 is closed, and no printing permission signal is applied to the printing section 7. Therefore, sales information for the third division is not printed on the checklist.

According to the example shown in the memory of FIG. 2, the sales information of the fourth department is printed after the second department on the checklist, but the sales information of the fifth and sixth departments are not printed.

This permission signal is controlled only at the time of inspection payment.
During registration and setting, information is always input to the printing unit 7 via the inverter 20 and the OR gate 19. Further, in the above embodiment, the operation was described only at the time of inspection, but the same applies to the time of payment.

By controlling as described above, FIG.
As shown in and b, the receipts and journals printed from the first cash register and second cash register respectively set in the same manner are
Data for each department is printed in the same order, and data for departments whose digit limit is "0" is not printed, making it easy to check the two tables.

Effects of the Invention As can be seen from the above explanation, the present invention stores specific data for each department in the memory of the cash register, for example, the input digit is "0", and stores this specific data in the memory at the time of inspection. The system is configured so that the printing of the department, etc. in which the above specific data is stored is deleted from this inspection/accounting sheet, so unnecessary data is not printed and efficient printing operation is achieved. It also makes it easier to check and compare with other inspection/settlement sheets. In addition, it is possible to print the necessary departmental transaction information at the time of inspection and payment by effectively using the digit restriction information that restricts the input information of the department, and there is no need to provide a special memory (flag) for printing restrictions. There is an advantage.
