Description

[Detailed Description of the Invention] [Industrial Application Fields] The present invention provides an electronic cash register in which an inspection task is divided into a plurality of types, for example, in order of confidentiality, and each inspection task can be executed using a dedicated task designation key. Regarding.

[Prior Art] In a general electronic cash register, there are buttons next to a keyboard provided on the front of the housing to select and set each task such as [registration], [inspection], [checkout], etc. A control key is provided that is operated using a designated key. [Registration Co., Ltd.] Stores sales data such as the department code, sales amount, and number of sold products entered manually from the keyboard into the departmental sales memory, cash sales memory, total sales memory, etc. formed in the storage unit. This is a normal sales registration operation that cumulatively registers in various memory areas, calculates the total amount for - customers, issues a receipt, and exchanges money for the total amount with the customers. Moreover, [inspection] is a task of printing out each data value cumulatively registered in each memory area of the storage unit on a receipt or the like as an inspection report at a predetermined fixed time, for example, after the start of sales operations. [Settlement Co.] For example, at the end of a day's work, each data cumulatively registered in each memory area in the storage unit is printed out as a settlement report, and the contents of each memory area that have already been printed are cleared. This is work to prepare for tomorrow's registration work.

[Problems to be Solved by the Invention] However, electronic cash registers configured to perform the above-mentioned tasks also have the following problems. That is, as described above, there are many types of memory areas formed within the storage unit. Therefore, these memory areas store relatively low-confidential data such as departmental sales memory, cash optical memory, and latch optical memory, and relatively sensitive data such as total sales memory and cashier-specific operating time memory. There are things that memorize highly sensitive data. Further, highly confidential data only needs to be grasped by the person in charge of the sales floor, and it is often not desirable for management to show such highly confidential data to general cashiers. Particularly in large-scale retail stores, one electronic cash register may be handled by many cashiers. However, if an inspection job is specified using the job specification key, the data in all memory areas will be printed out as an inspection report. Therefore, there is a problem that the cashier can see all the data.

There is also a concern that highly confidential data may be easily output by a third party manipulating the business specification key.

The present invention has been made based on these circumstances, and its purpose is to divide inspection work into multiple types, for example, in order of confidentiality, and execute inspection work using a dedicated work designation key for each type. An object of the present invention is to provide an electronic cash register that can protect highly confidential data from general cashiers and unforeseen accidents.

[Means for Solving the Problems] In the electronic cash register of the present invention, an inspection job in which each data value accumulated in each memory area of the storage unit is printed out as an inspection report can be printed out when this inspection job is designated. The system is divided into a plurality of types of inspection jobs with one type of memory area to be inspected, and is provided with a plurality of types of job designation keys that can each specify a predetermined inspection job among the divided inspection jobs.

[Operation: With an electronic cash register configured like this, minutes! Each of the inspected tasks cannot be executed without a designated task designation key, so by having the sales floor manager hold the task designation key for inspecting the memory area that stores highly confidential data, it is possible to Data can be kept confidential.

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

FIG. 2 is a perspective view showing the electronic cash register of the embodiment. As shown in the figure, a keyboard 2 is provided on the front surface of the housing 1, and a display section 3 is provided on the upper part of the housing 1 for electronically displaying the department code of the sold product, the total sales amount, etc.; A receipt issuing port 4 and a drawer 5 for storing cash are provided at the bottom.

Furthermore, a display section 6 for customers having the same configuration as the display section 3 is attached to the upper surface of the housing 1.

As shown in the figure, the keyboard 2 includes number keys 7 for entering sales amounts, sales quantities, etc. of sales products, and department keys 8 for indicating product classifications. Multiplication key to calculate the total amount when selling with credit other than cash 9. In addition to sales registration keys such as a deposit/cash total key 10 for calculating the total amount for cash sales, there are provided a cancel key 11, a control key 12 operated with a business designation key, and the like.

As shown in FIG. 3, the control key 12 can be operated with two business designation keys: a cashier key 13a used by the cashier and a manager key 13b used by the sales floor manager. keyhole 1 as shown in
4 is the above-mentioned 6 key 13a.

Each task can be specified by inserting and rotating 13b. That is, with the six keys 13a and 13b inserted into the keyhole 14, the power is turned on and the machine enters a hibernation state. Then, by rotating the cashier key 13a while it is inserted, you can select [Settings], [Pause], [Register], and [Inspection 1 item].
It is possible to select and specify four business modes: [Payment 1]. On the other hand, in the manager key 13b, in addition to the above four business modes that can be selected and specified with the cashier key 13a, ``Inspection 2'' and ``Payment 2'' can be selected and set.

Specifically, the cashier key 13a can only be rotated from the [setting] position to the [payment 1 position] due to the key shape shown in FIG. 3, and the person in charge key 13b can only be rotated from the [setting] position to the [payment 2 position]. is possible.

FIG. 4 is a block diagram of the electronic cash register. The CPU (Central Processing Unit) 15 has a built-in arithmetic circuit, etc., and performs various arithmetic processing based on input information from the keyboard 2, as well as an address bus 16. Data bus 17. A ROM 19 that stores fixed data such as programs for each of the above-mentioned operations via a control line 18, and a RAM 2 that stores sales data such as the sales amount of each product that has been manually input.
0 and operate. Also, a control key input circuit 21 to which a command signal from the control key 12 is input.
A keyboard input circuit 221 receives key signals from the keyboard 2; a display control circuit 23 sends display signals to the display sections 3 and 6; The printer control circuit 25 of the dot printer 24 that prints out sales data, total amount, various inspection reports, settlement reports, etc. on the receipt is connected to the data bus 17. It is connected to the CPU 15 via a control line 18.

In the RAM 20, as shown in FIG. 5, there is a departmental sales memory R1 in which sales data such as the number of sales items and sales amount of each sales item entered manually from the keyboard 2 is cumulatively registered for each department code. A totalizer R2 is used to calculate the total amount of products sold to customers, a cash sales memory R3 is used to accumulate the total amount of each cash sale using the deposit/cash key 10, and a multiplier key 9 is used. credit memory R4 that accumulates the total amount of each credit sale, correction memory R5 that accumulates the amount of sales that were later corrected due to returned goods, etc.
A total sales cumulative memory R6 is formed to accumulate the total sales amount, which is the sum of cash sales and credit sales. Also, this RAM
A cashier-specific operating time memory R7 is formed within the electronic cash register to accumulate the working hours of each cashier who performs sales operations at the electronic cash register. moreover,
[Settled flag A indicating that one transaction has been completed
A flag area R8 for storing the payment amount and a flag area R9 for storing the payment completed flag B indicating that the transaction of [Payment 2] has been completed are formed.

It should be noted that among the above-mentioned memories R1, R2-R7, the data cumulatively registered in the departmental sales memory R1, cash sales memory R3, and credit card memory R4 has a relatively low degree of confidentiality, and is stored in the correction memory R5 and total sales cumulative total. The memory R6 and the cashier-specific operating time memory R7 are relatively highly confidential.

The CPU 15 is configured to execute the inspection work according to the flowchart shown in FIG.

That is, when an inspection command is manually inputted from the keyboard 2 by manual operation of a combination key specified in advance, the control key 12 is activated by the work designation key 12a or 12b to select [Inspection 1].
] If the work mode is specified, it is determined that the inspection work for one inspection has started. Then, each data accumulated in the comparatively low-secrecy departmental sales memory R1, cash sales memory R3, and credit account memory R4 of the RAM 20 is printed out as an inspection report on a receipt by the dot printer 24.

In addition, when the inspection command is manually issued, the control key 12
is set to the [Inspection 2] task mode using the task designation key 13b, it is determined that the inspection task of [Inspection 2] has started. All memories R1, R3-R7 including RAM 20, relatively highly confidential correction memory R5, total sales cumulative memory R6, and operating time memory for each cashier R7.
The accumulated data is printed out on the receipt as an inspection report.

Further, the CPU 15 is configured to execute payment operations according to the flowchart shown in FIG. That is, when a payment command is manually inputted from the keyboard 2 by manual operation of a combination key specified in advance, if the control key 12 is designated to the [Payment 1] business mode by the work designation key 12a or 12b, the [Payment 1] is activated. ] It is determined that the settlement operation has started. Then, each data accumulated in the comparatively low-secrecy departmental sales memory R1, cash optical memory R3, and credit card memory R4 of the RAM 20 is printed out on a receipt by the dot printer 24 as a settlement report. Then, each data in each memory R1, R3, and R4 that has been printed out is cleared, and the cleared flag A in the flag area R8 is cleared.
Set to 1.

Note that the payment completed flags A and B are used to prevent the same payment transaction from being performed twice, and are cleared to 0 once data is stored in each memory in the [registration] transaction.

In addition, when the payment command is manually issued, the control key 12
is set to the [Settlement 2] business mode using the business designation key 13b, it is determined that the [Settlement 2] settlement business has started. All memories R1, R3-R7 including RAM 20, relatively highly confidential correction memory R5, total sales cumulative memory R6, and operating time memory for each cashier R7.
The accumulated data is printed out on the receipt as a settlement report. Then, each memory R1 that has been printed out,
Each data of R3 to R7 is cleared and the settled flag B in the flag area 8 is set to 1.

In the electronic cash register configured in this manner, each cashier only holds the cashier key 13a as a business specification key, and therefore can only perform the operations of [Inspection 1] and [Settlement 1]. Therefore, the data accumulated in the correction memory R5, the cumulative total sales memory R6, and the individual cashier operating time memory R7, which are highly confidential to the cashier, will not leak.

Further, the person in charge of the sales floor can obtain each data accumulated in all the memories R1, R3-R7 formed in the RAM 20 as an inspection report or a settlement report by using the person in charge key 13b. be.

Note that the present invention is not limited to the embodiments described above. In the embodiment, the inspection work is divided into two types: a case in which only one inspection can be carried out and a case in which it is possible to carry out one inspection and [inspection 2], but as shown in FIG. The inspection range of ~R7 may be set in four stages.

In this case, it is sufficient to prepare four types of business specification keys in ascending order of confidentiality. In addition, if the rotation range of the 6 keys becomes wider, as shown in Figure 8, power on/off control and common task 1 registration] [Even if a different common key is used to set the settings] good.

In addition, in the example, the [Settlement] work was divided into [Settlement 1] and [Settlement 2], but since [Settlement] is carried out at the end of the day's work, there is only one type of [Settlement]. Good too.

[Effects of the Invention] As described above, according to the present invention, inspection tasks are divided into a plurality of types, for example, in descending order of confidentiality, and the inspection tasks can be executed using the respective task designation keys. Therefore, highly confidential data cumulatively registered in each memory of the storage unit can be protected from unexpected accidents caused by general cashiers and third parties, and reliability can be further improved.
