Description

[Detailed description of the invention] [Industrial application field] This invention relates to electronic cash registers.

[Conventional technology] Conventionally, in electronic cash registers, when the power switch is turned on, the system starts up, imports product sales data from an input section such as a keyboard or barcode reader, registers that data in memory, and opens the drawer. There is a known system that enables a series of registration processes.

[Problem to be solved by the invention] However, in a device like this, where the system starts up immediately when the power is turned on and a series of registration processes can be performed, anyone can easily start the operation, so it is necessary to open the drawer. It was easy for people to handle money by using this method, which caused problems in terms of management.

This invention was made based on the above circumstances, and aims to provide an electronic cash register that can improve manageability.

[Means for Solving the Problems] The present invention provides an electronic cash register in which product sales data is taken in by operating an input unit, registered in a memory, printed out and issued, and a drawer is opened. A memory card with a PIN written on it, a card reader that reads the PIN of this memory card, a PIN register that stores the PIN read by this card reader, a number key for inputting the PIN, and a number of strokes. Comparison means is provided to compare the PIN entered by the key with the PIN stored in the PIN register to check for a match, and when the comparison means detects a match, product sales data can be captured and registered by operating the input unit. , which made it possible to open the drawer.

[Operation] In the present invention having such a configuration, after inputting the N source,
Insert the memory card into the card reader and enter the PIN number using the numeric keys. Only when the entered password matches the password read from the memory card can a series of registration processes such as importing product sales data, registration, and opening the drawer by operating the input section become possible.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

etc. are provided. Further, a drawer 7 is attached to the bottom of the casing 1, and a remote display 8 is attached to the top of the casing 1.

FIG. 2 is a block diagram showing the circuit configuration, in which numeral 11 is a CPU that constitutes the main body of the control section, 12 is a ROM that stores program data for this CPU 11 to control each section, and 13 is a block diagram showing the circuit configuration.
14 is a RAM equipped with the memory necessary for registration and various memories necessary for data processing, and 14 is a key-type control that switches and sets the business mode to ``registration'', ``inspection'', ``payment'', and ``setting''. An input port 16 controls the input of signals from the switch 15, and a clock circuit 16 counts the time and date.

Further, 17 is a printer controller that controls the printer 18, 19 is a display controller that controls the displays 3 and 8, 20 is a keyboard controller that controls the keyboard 21 and receives key signals from the keyboard 21, and 22 is the card A card reader installed inside the insertion slot 6.
This is a reader/writer controller that controls the writer 23 to read and write data to the magnetic card 5.

The printer controller 17 also has a drawer opening device 2.
4 to cause the device 24 to open the drawer 7.

The CPLJ 11, ROM 12, RAM 13, input port 14, clock circuit 16, and each controller 17.19.2
0.22 is electrically connected by a pass line 25, and data and control signals are transmitted.

The control switch 15 and the keyboard 21 constitute the input section 2, and the keyboard 21 is provided with a number key, a department key, a multiplication key, a clear key, a registration closing key, and the like.

As shown in FIG. 3, the RAM 13 is set with a password register 13a, a power counter 13b, a person buffer 13c, a display buffer 13d, a print balance 1301, a department total fi 13f, a transaction total 13g, and an eight-digit password. An 8-digit number setting memory 13h and the like are provided.

As shown in FIG. 4, the magnetic card 5 is set with, for example, a four-digit PIN number at the beginning, followed by a space and then the registered department code, sales quantity, sales amount, and time data are sequentially loaded. It is now possible to

The CPtJ 11 is programmed to perform the process shown in FIG. 5 immediately after the power is turned on. That is, first, the magnetic card 5 is on standby to be inserted from the card insertion slot 6. When the magnetic card 5 is inserted, the card reader/writer 23 is driven to read the password from the magnetic card 5 and store it in the password register 13a.

Next, press the number key to wait for human power. When a four-digit password is input using the numeric keys, the input password is compared with the password already stored in the password register 13a to check whether they match. (comparison means) and when it is determined that the comparison results match,
Importing and registering product sales data by operating the input unit 2,
Allows opening of drawers, etc. If they do not match, the counter 13t) is incremented by 1 and the password is read from the 1FM card 5 again, and the password is input and compared. Then, until the counter 13b counts "5", that is, when a match is not determined even after 5 repetitions, the 8-digit common password is input using the numeric keys.

When an 8-digit PIN is entered, the PIN is compared with the PIN stored in the 8-digit number setting memory 13h, and if a match is found, the product sales data is entered by operating the input section 2. Enables import, registration, opening of drawers, etc.

In a state in which the input unit 2 can be operated, the CPU 11 executes a registration task when the "registration" mode is specified with the control switch 15, for example.

In this registration process, the number must be entered using the numeric keys and multiplication keys of the keyboard 21; however, in the case of one item, this key operation is not necessary. ), when the unit price is input using the numeric key and the department key is operated, the sales quantity and sales amount, which are product sales data, are classified by department code and accumulated in the department totalizer 13f. In addition, display data is stored in the display buffer 13d,
The display 3.8 is controlled and displayed. It also stores print data in the print buffer 13e and controls the printer 18 to print and output the data on each sheet of receipt and journal paper.

When this department registration is performed and the closing key is operated on the keyboard 21, the total amount registered in the department is accumulated for each transaction in the transaction totalizer 13a, and the total amount is printed on the receipt and journal paper by the printer 18. Output and cut and issue a receipt. Furthermore, the drawer opening device 24 is driven to open the drawer 7. Furthermore, the card reader/writer 23 is controlled to write the department code, number of sold items, sales amount, and time of the clock circuit 16 on the magnetic card 5.

In this embodiment having such a configuration, the input unit 2 cannot be operated at all simply by turning on the If source. In this state, the magnetic card 5 is inserted into the card insertion slot 6, and a four-digit password is entered using the number keys on the keyboard 21. When the entered password matches the password set on the magnetic card 5, it becomes possible to import product sales data, register, open the drawer, etc. by operating the input section 2.

If the passwords do not match, you can enter the password again, so if you make a mistake, you can start over. In addition, if there is an abnormality in the magnetic card 5, the password will not match even if you enter the password five times, so in this case, enter the commonly set 8-digit password to the manager, for example. do that for me. This allows the input section 2 to be operated.

In this way, unless you insert the magnetic card 5 and enter the same password as the one set on the card 5, you will not be able to register product sales data or open the drawer 7, etc. There is no possibility of someone other than the operator opening the drawer without permission. In other words, the device can be managed reliably and manageability can be improved.

Furthermore, since the data registered by the operator is written in the magnetic card 5, it is possible to later read the magnetic card into a personal computer or the like using a card reader and perform various classification and tally operations. In other words, it is not necessary to incorporate a classification and totaling program into the cash register. Therefore, it is extremely effective when using multiple cash registers. In this case, if a large-capacity memory card such as a RAM card or an IC card is used instead of the magnetic card, coarsely detailed data can be stored and highly accurate classification and aggregation can be performed.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to provide an electronic cash register that can improve manageability.
