Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention is applicable to POS. It relates to cash registers such as ECRs (electronic point-of-sale cash registers).

0002

2. Description of the Related Art Conventionally, this type of POS. In cash register machines such as ECRs, it is necessary to strictly manage the equipment. For this reason, keys are provided for administrators, persons in charge, etc., and depending on the type of key, the range of functions that can be operated is restricted, and the person in charge of operations is identified.

[0003] That is, switching the operation mode is usually
This is done by assigning "setting mode", "registration mode", "inspection mode", "accounting mode", etc. to the rotational position of the key, and turning the key to that rotational position. The rotation range is changed depending on the type of key switch, for example, a key switch for an administrator can be rotated to all positions, and a key switch for a person in charge can be rotated only to the "registration mode".

[0004] Furthermore, the person in charge is identified by reading out the shape of the key using a plurality of mechanical contacts and encoding it.

FIG. 5 is a circuit block diagram showing the circuit configuration of a conventional cash register. In this figure, 1 is a mechanical key switch, and by rotating this key switch 1, it is possible to select various operation modes such as setting mode, registration mode, inspection mode, and payment mode.

Reference numeral 2 denotes an input port into which operation mode specification data is input from the key switch 1, 3 a keyboard into which various monetary registration data are input, and 4 a key interface which sends a key scan signal to the keyboard 3 and receives a return signal. , 5 is a CPU, 6 is a ROM, and 7 is a RAM.

As shown in FIG. 5, conventionally, CP
U5 reads the mode status from input port 2 of key switch 1 and enables operation in that mode. For example, if the operator is only permitted to perform settings and registration operations, he or she will be provided with a key that can only be rotated to the position of that mode. In addition, the administrator is provided with a key that can be rotated in all ranges so that the administrator can operate in all modes.

[0008]

[Problem to be Solved by the Invention] However, in conventional cash registers, as mentioned above, it is necessary to prepare keys of various different types, and in particular, the more people involved in the operation, the more keys of different shapes have to be prepared. Because it requires many keys,
This increases costs and makes storage and other management difficult. Furthermore, because of its mechanical structure, it is not possible to create many types of keys, and since it is not a special key, it is easy to forge, which poses security problems.

[0009] The present invention was made in consideration of the above circumstances, and the mechanical key switch part for changing the operation mode and identifying the person in charge is converted into an electronic switch by using a memory card. It provides a cash register.

0010

[Means for Solving the Problems] FIG. 1 is a block diagram showing the configuration of the present invention. As shown in the figure, the cash register according to the present invention has a memory in which the type of operation mode selected from various operation modes such as setting mode, registration mode, inspection mode, payment mode, etc. is written as an operation range. Consists of a cash register main body 103 having a card 101 and a connector 102 into which the memory card 101 can be attached,
The cash register main body 103 includes a specifying means 104 for specifying various operation modes such as a setting mode, a registration mode, an inspection mode, and a payment mode, and a reading means 105 for reading an operation range from a memory card 101 via a connector 102.
A determining means 106 that determines whether the operation mode specified by the specifying means 104 is included in the operation range read by the reading means 105, and when it is determined by the determining means 106 that the operation mode is included in the operation range. A memory card equipped with an execution means 107 for executing money registration processing in a specified operation mode, and a notification means 108 for notifying an operation error when it is determined by the determination means 106 that the money registration process is not included in the operation range. It is a cash register.

[0011] As the designation means 104 in the present invention, a keyboard or the like is used which can designate various operation modes such as setting mode, registration mode, inspection mode, and payment mode.

The reading means 105, the determining means 106 and the executing means 107 include a CPU, ROM, RAM, I/O
It is convenient to use a microcomputer with an O port.

As the notification means 108, various display devices, buzzers, lamps, etc. are used.

[0014]

[Operation] According to the present invention, when the operation mode is designated by the designation means 104, the operation range is read from the memory card 101 by the reading means 105, and the determination means 1
06, it is determined whether the operation mode specified by the specifying means 104 is included in the operation range read by the reading means 105.

[0015] If it is within the operation range, the execution means 107 executes the money registration process, and if it is not within the operation range, the notification means 108 notifies you of an operation error.

[0016] Therefore, if each person in charge has a memory card on which the operating range is written and the memory card is inserted into the cash register at the time of operation, each person in charge can operate the cash register in a different range. This makes it possible to set various operation modes than before, and eliminates the need for a conventional mechanical key switch.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments shown in the drawings. Note that this invention is not limited to this.

FIG. 2 shows this invention in a POS. 1 is a circuit block diagram showing a circuit configuration of an embodiment applied to an ECR (electronic cash register for point-of-sale management); FIG.

In this figure, reference numeral 1 denotes a memory card with a built-in IC memory, and this memory card 1 stores operations selected from various operation modes such as setting mode, registration mode, inspection mode, payment mode, etc. The type of mode is written as the operating range.

2 is a POS.2 having a connector 3 into which a memory card 1 can be attached. This is the ECR body.

4 is POS. This is a keyboard provided on the ECR main body 2. On the keyboard 4, push keys (not shown) are provided that correspond to each operation mode, such as setting mode, registration mode, inspection mode, and payment mode.

5 is a key interface that sends a key scan signal to the keyboard 4 and receives a return signal; 6 is an input/output buffer that temporarily stores data when inputting and outputting data to and from the memory card 1 via the connector 3;
7 is a CPU, 8 is a ROM, and 9 is a RAM.

A control program is written in the ROM 8, and the CRU 7 performs various data processing based on the control program written in the ROM 8.

That is, the CPU 7 reads the operation range from the memory card 1 via the connector 3. Then, when various operation modes such as setting mode, registration mode, inspection mode, payment mode, etc. are specified by pressing a push key on the keyboard 4, whether the specified operation mode is included in the read operation range or not. If it is within the operation range, the money registration process is executed in the specified operation mode, and if it is not within the operation range, a buzzer (not shown) is used to notify an operation error.

FIG. 3 is an explanatory diagram showing an example of the contents of the operation range written in the memory card 1. As shown in FIG. An operation range flag is written in the memory card 1 as an operation range in a data structure as shown in the figure. “1” for each flag
indicates that operation in that mode is possible,
If it is "0", it indicates that operation in that mode is not possible.

Therefore, in the example shown in this figure, the operator who owns this memory card 1 can perform registration and inspection operations.

Next, the contents of the processing operation of the CPU 7 will be explained with reference to the flowchart shown in FIG. When an operation in a certain mode is to be executed, that mode is first designated, and in that case, the operator presses a push key corresponding to that mode.

When the push key corresponding to the operation mode is pressed (step 11), the CPU 7 reads the operation range flag stored in a predetermined area of the memory card 1 (step 12), Determine whether the operation is permitted. That is, it is determined whether the operation range flag is 1 (step 13),
If the operation range flag is 1, it is considered that the operation is possible, and if the operation is possible, the subsequent processing is executed in that mode (step 1
4). Further, if the operation range flag is not 1, it is assumed that the operation is not possible, and if the operation is not possible, an operation error is processed (step 15).

In this way, one type of memory card 1 is prepared regardless of the number of operators, and an operation range flag or operator code is stored in a predetermined area of the memory card 1 in advance according to the person in charge. , transaction limit code, etc., can be used at POS without using a conventional key switch. Appropriate management of ECR becomes possible.

[0030]

[Effects of the Invention] According to the present invention, each person in charge has a memory card with the operating range written on it, and when operating the machine, the memory card is attached to the cash register and the operation can be performed in the designated mode. Since it is determined whether or not this is the case, it is possible to appropriately manage the cash register without using a conventional mechanical key switch.

[0031] Furthermore, since it can be handled by simply changing the code to be written based on a common card, there is no need to prepare many different types of keys as in the past, and the types of codes to be written can be increased arbitrarily. becomes possible. moreover,
Since only the writing code is changed inside the card, it is difficult to forge and is extremely advantageous in terms of security.
