Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to an electronic cash register (hereinafter referred to as E).
9R), and particularly relates to a FOR that can distinguish the functions that can be operated by each operator.

[IIIM of the Invention] This invention provides an ECR in which information regarding functions that are permitted to be operated or functions that are prohibited to be operated is stored in a storage means, and an operator can perform any of the functions. When an operation is performed to execute a function, it is determined based on the information stored in the storage means whether the function is a function that is permitted for the operator, so that the function can be operated by each operator. This allows the functions to be distinguished.

[Prior Art] With the development of electronic technology, recent ECRs have become capable of performing various functions. However, some of these functions, such as a report function regarding store sales, are not suitable for ordinary operators to operate. In the conventional E'OR, the shape of the key inserted into the mode key (cylinder lock key switch) for switching the ECR operation mode is changed depending on the operator, so that the functions that can be operated by each operator can be adjusted. They were differentiated according to their authority. . For example, the key held by a general operator can only turn the mode key to the selection position for product registration, and therefore the general operator can only operate the product register. On the other hand, the key held by the administrator can rotate the mode key to any selected position, and therefore the administrator can operate any function. '1 [Problems to be Solved by the Invention] By the way, recent ECRs have various functions, so it has been impossible to switch all of them using the mechanical mode key as described above. Therefore, the operation mode selected by the mode key is a rough classification of detailed functions, and a plurality of types of functions can be executed in each operation mode. Therefore, in conventional ECRs such as those mentioned above, in which the functions that can be operated by the operator are separated in relation to the mode keys,
Only a rough distinction could be made, and it was not possible to distinguish between operators the detailed functions performed in each operating mode. Furthermore, there is a limit to changing the shape of the mode key, and it is not possible to distinguish between the functions that each operator can operate individually.

Therefore, an object of the present invention is to provide an ECR that allows finely distinguishing the functions that can be operated by each operator, and that allows the content of the distinction to be easily changed.

Means for Solving Problem E] The present invention provides a storage means for storing information regarding functions that a certain operator is permitted to operate or functions that are prohibited from being operated; determining means for determining whether or not the function is a function permitted for the operator when an operation for avoiding the execution of the function is performed, based on information stored in the storage means;
and a processing means for executing processing related to the function in response to the determination in stage f that the function is permitted for the operator.

[Operation] In the present invention, when the operator performs an operation for executing any of the functions, the determining means stores information 4x on the storage means as to whether or not the function is a function permitted to the operator. The determination is made based on stored information, and when it is determined that the function is permitted for the operator, the processing means executes processing related to the function.

Current total key 39 is used as a conversion table for generating a predetermined function code in accordance with the operating mode at that time when any of the III function keys of the currency exchange key 35 is pressed. For this purpose, the M/C function code table 73 records function codes for each function key for each operation mode of registration 9 inspection and fine sieve. This indicates that various functions as shown in the figure are executed depending on the selected position of the mode key 30 and the key sequence. FIG. 8 also shows function codes and subcodes that are predefined for each function.

FIG. 1 is a flowchart for explaining the operation of CPLll shown in FIG. Below, the above figure 8 and 1
The operation of one embodiment of the present invention will be described with reference to the drawings.

In this embodiment, a responsible person code is assigned to each operator in advance, and the operator is required to input this responsible person code first when operating the ECR (see Figure 8). ).

First, the operation of setting permitted function hoods in the operator-specific permitted function code table 72 shown in FIG. 6 will be described. Note that this setting operation is performed in the setting mode. First, in step S1, the CPU clears the working memory 71 and clears the initial SET flag 714.
Turn on.

Subsequently, the process advances to step S2, and the numerical code input from the numeric keypad 32 is stored in the input buffer F711 until the function key is pressed. The numerical code stored in the manual buffer 711 at this time is the responsible person code. Next, the process advances to step S3, and it is determined whether the initial SET flag 714 is turned on. Initial SET flag 714
If it is turned on, the process advances to step S4, where the operation mode selected by the mode key 30 at that time is read, and the code corresponding to this operation mode is stored in the mode area 712. The operations in steps S3 and S4 are performed in order to continue the previous mode even if the mode is changed during operation. Next, the process advances to step S5, and it is determined whether the content of the mode area 712 is the setting mode. Since it is the setting mode at this time, the process advances to step S6, and it is determined whether or not the person in charge key 34 has been pressed. If a function key other than the person-in-charge key 34 is pressed, it is an operational error, so step S1
Return to operation. On the other hand, if the person in charge key 34 is pressed, the process advances to step S7, where the person in charge code stored in the input buffer 711 is read and the address of the operator-specific permission function code table 72 corresponding to the person in charge code is set. Set to pointer 713. Subsequently, key manual processing is performed in step S8. That is, numerical data input from the numeric keypad 32 is stored in the input buffer 711 until a function key is pressed.

The numerical data input from the numeric keypad 32 at this time is a function code or subcode. Next, step S9
The process proceeds to step 201, and it is determined whether or not the subtotal key 38 has been pressed.

If the subtotal key 38 is pressed, the process advances to step 810, and the function code and subcode stored in the manual buffer 711 at that time are set in a predetermined area of the per-operator permitted function code table 72 indicated by the setting pointer 713. . Subsequently, the process advances to step 811, where the setting pointer 713 is incremented. Thereafter, the process returns to step S8. When the setting of the function code or subcode is repeated as many times as necessary and the current total key 39 is pressed, step 8
This is determined in step S12, and the process returns to step S1. This completes the setting of function codes and subcodes for one operator.

The series of operations described above is performed for each operator, and the operator-specific permitted function code table 72 is all set, and this table does not change until it is set again.

Next, the operation when the operation is performed in either the registration 1 inspection or payment operation mode will be explained. As mentioned above, even when operating in either the registration 1 inspection or payment operation mode, the operator must first enter his or her responsible person code from the numeric keypad 32 and then press the responsible person key 34. It is being The entered responsible person code is
The data is stored in the input buffer 711 in step S2.

Thereafter, it is determined in step S5 that the operation mode is not the setting mode, and the process proceeds to step 813, where the person in charge key 3
4 is determined to be pressed. Next, proceed to step 814;
It is determined whether the initial 5IET flag 714 is turned on. If the initial SET flag 714 is not turned on at this point, it is determined that an operation error has occurred, and error processing is performed. On the other hand, initial SET flag 7
14 is turned on, proceed to step 815;
Data from the permission function code table 72 corresponding to the person-in-charge code stored in the input buffer 7P711 is read and loaded into the permission buffer 717. The contents of this permission buffer 717 are referenced during subsequent operations in order to determine whether to permit or prohibit the operated function.

Next, when a function key other than the person in charge key 34 is pressed,
Proceed to step 816. In step $16, a function code predefined by a combination of a function key (including a department key) and an operation mode is read from the M/C function code table 73 and set in the input function code area 715.

Subsequently, after the subcode area 716 is cleared in step 817, the process advances to step 818. This step 8
In step 18, it is determined whether the function code stored in the input function code area 715 represents an inspection report or a settlement report. As shown in FIG. 8, when creating an inspection report or a settlement report, a two-digit report code is input and then the cash total key 39 is pressed.

This report code is stored in the input bag 7?711 in step S2. If it is determined in step 818 that the function code represents report creation, the process proceeds to step 819, where the report code stored in the input buffer 711 is set in the subcode area 716 as a subcode. After the child, proceed to step 820. On the other hand, if it is determined in step 818 that the function code does not represent report creation, the function code is directly
Proceed to step 20. In this case, the content of the subcode area 716 is "o o". In step 820, a search is made to see if there is a food in the permission buffer 7717 that matches the function code and subcode set in the input function code 1 rear 715 and subcode area 716. The process then proceeds to step 821, where it is determined whether or not a matching code is found as a result of the search in step 820. If there is no matching code, it means that the function operated by the operator at that time is not permitted for the operator, so error processing is performed and processing for that function is prohibited. On the other hand, if there is a matching code, step S2? Proceed to
Input function code area 715 and subcode area 7
Processing corresponding to the function code and subcode set to 16 is performed. After the processing is completed, the initial SET flag 714 is turned off. If the process performed at this time is a process in the middle of one transaction, such as department registration, discount registration, 10% discount registration, and subtotal display, there is a process to be continued, so the process returns to step S2 described above. On the other hand, if there is no further processing to be performed, such as cash transaction 9 currency exchange 9 creation of inspection report and creation of settlement report, the process returns to step S1 described above.

In addition, in the above-mentioned embodiment, the per-operator permission function code table 72 is provided inside the RAM 7;
If a card is issued to each operator and the functions that each operator can operate are recorded on this card, the above-mentioned operator-specific permitted function code table 72 will be unnecessary, and the RAM
7 storage capacity can be reduced. Furthermore, setting operations for function codes for each operator can be omitted.

The configuration and operation of such other embodiments will be explained below.

one! In the second embodiment, a card reader 2 is connected to the CPU 1 shown in FIG. Then, the card reader 2 reads the data recorded on the card for each operator. Further, a card buffer 718 as shown in FIG. 9 is provided in the RAM 7.

This card buff? 718 stores function codes and subcodes read from cards for each operator.

FIG. 2 is a flowchart for explaining the operation of another embodiment. The flowchart in FIG. 2 is similar to the flowchart in FIG. 1 except for the following points, and corresponding parts are given the same step numbers. In the embodiment of FIG. 2, after initial SET processing is performed in step S1, key manual processing in step 830 is performed.

In this manual key processing of step 830, numerical data input from the numeric keypad 32 is stored in the input buffer 1711 until a function key is pressed or a card is scanned into the card reader 2. Note that when the card is scanned, a key code indicating card input is set in the input buffer 711. After that, the operation mode is set in steps S3 and S4, and then step S
At step 31, it is determined whether or not a card has been inserted. If there is a card input, the process advances to step 832 and the card data read by the card reader 2 is stored in the card buffer 1718. Then, the process proceeds to step 833, where it is determined whether or not there is a card input. If there is a card input, the initial SET flag 71 is set at step 814.
4 is determined to be on, the function code and subcode data of the card buffer 7718 are loaded into the permission buffer 717 in step 834. Thereafter, this permission buffer 1717 is used to determine whether or not to permit the input function. The subsequent operations are similar to those shown in FIG.
