[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register that allows interruption registration of a person in charge of operation called a cashier.

0002

[Prior Art] For example, in a fast food restaurant where products are sold face-to-face across the counter, multiple electronic cash registers are installed above the counter, and several people called cashiers are assigned to operate the electronic cash registers. It is placed inside. Then, each operator operates the keyboard of a nearby electronic cash register to register the ordered products of the customers they serve, and after registration, they sort the products. When the assortment is completed, the customer operates the closing key of the registered electronic cash register to display the total amount on the display, and receives payment from the customer for the displayed amount.

[0003] In this case, it takes some time to assemble the ordered products. Therefore, with the electronic cash registers used in fast food restaurants like this, one person in charge of operation is registering and arranging the products ordered by a customer, while another person in charge of operation is registering and arranging the items ordered by a customer. The company aims to streamline the registration process by allowing customers to register ordered items without interruption.

[0004] Conventionally, electronic cash registers capable of registering interrupts as described above have been disclosed, for example, in Japanese Patent Laid-Open No. 1-15
There is one described in Publication No. 9792. This thing is
When a customer's ordered product is registered, the product sales data is cumulatively registered in the registration memory and sequentially stored in the detail table. Also, the product sales data is sequentially printed on the receipt using the printer. If the interrupt key is operated here to declare interrupt registration of another customer, the receipt being printed is invalidated. When a product ordered by another customer is registered in this state, the product sales data is cumulatively registered in the registration memory, but not stored in the details table. At this time, the product sales data is printed on the receipt using the printer. When the interruption registration is finalized, the registration total of the interruption customers is calculated, and the total amount is printed and issued on a receipt. Next, the product sales data of the interrupted customer stored in the details table is sequentially printed on the receipt to return to the state before the interruption. Thereafter, when the registration closing operation is performed, the registration total of the interrupted customer is calculated, and the total amount is printed and issued on a receipt.

[0005]

[Problem to be Solved by the Invention] However, in the electronic cash register of the above-mentioned publication, if the person in charge of the operation who has registered the interruption does not perform the closing operation and complete the issuance of the receipt to the customer who interrupted, the person responsible for the interruption cannot be held responsible for the operation. The tightening operation by a person was not possible. Therefore, there is no problem if the time required to arrange the goods for the interrupting customer is short, but if it takes a long time, the person in charge of the interrupted operation cannot perform the closing operation for the customer, resulting in a decrease in work efficiency.

[0006] Therefore, the present invention provides that even if an operator in charge interrupts another operator's registration in the middle of registration by another operator in charge, the operator in charge who is interrupted can perform the closing operation before the operator in charge of interrupting the registration. Moreover, the present invention aims to provide an electronic cash register that can issue a receipt to each customer regardless of whether or not there is an interruption, thereby reliably improving business efficiency and ensuring sufficient serviceability.

[0007]

[Means for Solving the Problems] The present invention has a display device that displays the price, cumulatively registers product sales data input through input operations in a registration memory, and calculates one customer per customer through a registration closing operation. In an electronic cash register that displays and outputs registered total data on a display,
A printer that prints receipts, a person instructing means for instructing a person in charge of inputting and closing operations, a save buffer that sequentially stores product sales data and registered total data for each customer for each person in charge of operations, and a save buffer that sequentially stores product sales data and registered total data for each customer, and A product sales data writing means for writing the product sales data into a save buffer for each operating person instructed by the instruction means when the sales data is input, and an instruction means when the total registered data for one customer is calculated by the closing operation. a registered total data writing means for writing the registered total data into a save buffer for each person in charge of operation as instructed by the operator; an instruction key for instructing receipt printing; The apparatus is equipped with a receipt printing control means for sequentially printing out product sales data and registered total data stored in the save buffer for each person in charge of operation using a printer.

[0008]

[Operation] In the present invention having such a structure, each person in charge of operations uses the person-in-charge instruction means to declare that he/she will operate the product before inputting product sales data or closing registration. By doing so, the product sales data and the registered total data for each customer are sequentially stored in the save buffer for each person in charge of operation. Then, when the operator instructs to print a receipt by operating an instruction key, the printer prints out the product sales data and registered total data for each operator who is stored in the save buffer.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an electronic cash register, in which a CPU (central processing unit)
1 via bus line 2 to ROM (read only memory) 3 and RAM (random access memory) 4
A microcomputer as a main body of the control unit is constructed by connecting the memories of the above. Then, the CPU 1 has a clock circuit 5 that measures the date and time, ``registration'', ``inspection'', ``payment'',
An I/O port 9 receives a signal from a mode switch 6 for selecting various business modes such as "Setting" and outputs a drive signal to a drawer opening device 8 that opens a drawer 7, and corresponds to input keys from a keyboard 10. A keyboard controller 11 that takes in key data to be displayed, a display controller 13 that drives and controls a display 12 that displays amounts, etc., and a printer controller 15 that drives and controls a printer 14 that prints on receipts and the like are connected. It functions as an electronic cash register.

As shown in FIG. 2, the keyboard 10 includes number keys 21 for entering numerical data such as the sales amount and number of products sold, and a plurality of preset department codes for classifying each product. A department key 22, a current total key 23 as a closing key for instructing to close registration, a multiplication key 24 for instructing input of a multiplier, a clear key 25 for instructing clearing of numbers and error cancellation, and instructions for printing a receipt. An issue key 26 is provided as a key, and person keys 27a to 27e are provided as person in charge instruction means in which a person in charge code assigned to each person in charge of operation is preset.

The ROM 3 stores in advance fixed data such as program data for the CPU 1 to execute various tasks and character generator data for printed characters and display characters.

On the other hand, the RAM 4 includes a registration memory 31 for cumulatively registering product sales data, as shown in FIG.
Various memory areas are formed, including a number register 32 for temporarily storing numerical data, a print buffer 33 for temporarily storing print data, and a display buffer 34 for temporarily storing display data. Further, a table 40 by person in charge shown in FIG. 4 is formed.

The responsible person table 40 includes flag areas 4 of instruction flags F1 to F5 for each responsible person code preset to each of the responsible person keys 27a to 27e.
1, a totalizer area 42, and a save buffer 43 that sequentially stores product sales data and registered total data for one customer.

[0015] When a power switch (not shown) is turned on, the CPU 1 executes a predetermined initialization process. By this initialization process, the totalizer area 42 and save buffer 43 of the responsible person table 40 are
is cleared. Further, each instruction flag F1 to F5 in the flag area 41 is reset to "0". After that, when one of the person in charge keys 27a to 27e is operated to input while the "registration" mode is selected by the mode switch 6, it is determined that the sign-on operation has been performed by the person in charge of operation, and the input key is pressed. The instruction flag corresponding to the preset responsible person code is set to "1". This enables registration operations using the electronic cash register.

In this state, the CPU 1 waits for a key input from the keyboard 10, and is programmed to execute a key input routine shown in FIG. 5 when a key input is made. That is, when the numeric key 21 of the keyboard 10 is inputted, the numeric data is transferred to the numeric register 3.
2 and displayed on the display 12. On the other hand, if a key other than the numeric key 21 is input,
The input key process of the business mode selected by the mode switch 6 is executed.

FIG. 6 shows the key processing when the department key 22 is inputted when the registration mode is selected. If no numerical data is stored in the number register 32, the sales amount is not entered. Since the department key 22 was operated, the key input is treated as an error. When numerical data is stored in the number register 32, the person in charge corresponds to the instruction flag set to “1” among the instruction flags F1 to F5 in the flag area 41 in the person-in-charge table 40. The contents of the separate totalizer area 42 are investigated. If the content is “0”, the save buffer 4 by person in charge corresponding to the instruction flag = “1” in the table 40 by person in charge
Clear 3. If the value is other than "0", the clearing process described above is not performed. After that, the numerical data in the number register 32 is set as the unit price of the product to be sold, and the unit price is added to the number of sales items (if a multiplier has been entered using the multiplication key 24 immediately before, the multiplier; otherwise, "1") ) to calculate the sales amount. Then, the sales data is cumulatively registered in the registration memory 31 for each department code preset in the input department key. In addition, table 40 by person in charge
The sales amount is added to the person-in-charge totalizer area 42 corresponding to the instruction flag=“1”. Furthermore, the product sales data consisting of the department code, sales amount, and number of items sold is written in the save buffer for each person in charge corresponding to the instruction flag = "1" in the person in charge table 40 (product sales data writing means), and this key processing is performed. end.

FIG. 7 shows the key processing when the current total key 23 is inputted when the registration mode is selected. Investigate the contents of area 42. If the content is "0", the key input is treated as an error because the closing operation was performed before the product was registered. If the value is other than "0", the content is displayed on the display 12 as the total amount. Also, the registered total data consisting of the above total amount is written to the responsible person save buffer corresponding to the instruction flag = "1" in the responsible person table 40 (registered total data writing means)
. After that, the instruction flag of the above table 40 by person in charge =
The person-in-charge totalizer area 42 corresponding to "1" is cleared, and this key processing is ended.

FIG. 8 shows the key processing when the issue key 26 is inputted when the registration mode is selected. First, the save buffer 43 for each responsible person corresponding to the instruction flag = "1" of the table 40 for each responsible person is Investigate the contents of If no data is stored in the buffer 43, the key input is treated as an error because an unregistered operator has instructed printing of the receipt. If data is stored, then the contents of the corresponding totalizer area 42 for each person in charge are investigated. If the content is "0", the key input is treated as an error because a receipt printout was instructed before the registration closing operation. If the value is other than "0", the printer 14 sequentially prints the contents of the corresponding person-specific save buffer 43 on receipt paper, issues a receipt (receipt printing control means), and ends this key processing.

FIG. 9 shows the person in charge key 27 when selecting the registration mode.
This shows the key processing when one of a to 27e is inputted, and the instruction flag corresponding to the person in charge code preset to the input key of the person in charge table 40 is set to "1", and the remaining instructions are executed. All flags are reset to "0" and this key processing is completed.

Next, the effects when the electronic cash register constructed as described above is used in a fast food restaurant where products are sold face-to-face across the counter will be explained.

[0022] For convenience of explanation, the operation manager A with the manager code [1] is responsible for the product (unit price 100) with the department code [01].
yen) and department code [03] (unit price: 300 yen), and while they were sorting out the products, Operation Supervisor B with supervisor code [2] Product with department code [01] (unit price 200 yen) and department code [01]
02] (Unit price: 200 yen). Interact with customers who order one item each and assemble the product. During that time, the operation manager A completes the product assortment and performs the closing operation, and after issuing a receipt, the operation manager C with the manager code [3] buys only one product (unit price 400 yen) with the department code [04]. Interact with customers ordering. A case will be described in which the operator B completes the assortment and performs a closing operation during the assortment, and after issuing a receipt, the operator C completes the assortment, performs the closing operation, and issues a receipt.

In this case, the operation manager A first inputs the manager key 27a, then enters "100" using the number keys 21, operates the department key 22 for the department code [01],
Next, the user enters the number "300" using the number key 21 and operates the department key 22 for the department code [03]. This results in
First, the responsible person key processing shown in Figure 9 creates the responsible person table 4.
The instruction flag F1 corresponding to the responsible person code [1] of 0 is “
1”, and the remaining instruction flags F2 to F5 are set to “0”.
". Then, by the department key processing in Figure 6, the product sales data "department [01], amount [100], score [1]" and product sales are stored in the save buffer corresponding to this person in charge code [1]. Data “Department [03], Amount [3]
00], score [1]” are stored sequentially. Also, the total amount 40 is displayed in the totalizer area 42 corresponding to the person in charge code [1].
0 yen is stored.

Next, after the operation manager B inputs the manager key 27b, he enters "200" using the numeric key 21, operates the department key 22 for the department code [01], and then presses the numeric key 21. 21, enter “200” and enter the department code [02
] is operated. As a result, the instruction flag F2 corresponding to the responsible person code [2] in the responsible person table 40 is set to "1" in the same way as above, and the remaining instruction flags F1 and F3 to F5 are reset to "0". Ru. Then, the product sales data “Department [01], Amount [200]” is stored in the save buffer corresponding to this manager code [2].
], score [1]" and product sales data "department [02], amount [200], score [1]" are stored in sequence. Further, a total amount of 400 yen is stored in the totalizer area 42 corresponding to the person in charge code [2].

Next, the operator A who has completed the product assortment inputs the person in charge key 27a, and then inputs the total key 23. As a result, the responsible person code [1] of the responsible person table 40
After the instruction flag F1 corresponding to the instruction flag F1 is set to "1" and the remaining instruction flags F2 to F5 are reset to "0",
By the current total key processing in FIG. 7, the contents [400] of the totalizer area 42 corresponding to the responsible person code [1] are displayed on the display 12 as the total amount. Further, the total amount is stored as registered total data in the save buffer 43 corresponding to the responsible person code [1], and the totalizer area 42 is cleared. Thereafter, the person in charge of operation A inputs the issue key 26. As a result, the contents of the save buffer 43 corresponding to the responsible person code [1] are sequentially printed out on receipt paper by the printer 14, and a receipt 51 as shown in FIG. 10 is issued.

Next, after the operation manager C inputs the manager key 27c, he enters "400" using the number keys 21 and operates the department key 22 for the department code [04]. As a result, the instruction flag F3 corresponding to the person-in-charge code [3] in the person-in-charge table 40 is set to "1", and the remaining instruction flags F1, F2, F4, and F5 are reset to "0". Then, the product sales data "Department [04], Amount [4]" is stored in the save buffer corresponding to this person in charge code [3].
00], score [1]” are stored. Further, a total amount of 400 yen is stored in the totalizer area 42 corresponding to the person in charge code [3].

Next, the operation manager B who has completed the product assortment inputs the manager key 27b, and then inputs the current total key 23. As a result, the responsible person code [2] of the responsible person table 40
After the instruction flag F2 corresponding to this person code [2] is set to "1" and the remaining instruction flags F1 and F3 to F5 are reset to "0", the content of the totalizer area 42 corresponding to this responsible person code [2] is set to "1". 400] is displayed on the display 12 as the total amount. Also, the total amount is the responsible person code [2]
The registered total data is stored in the save buffer 43 corresponding to the registered total data, and the totalizer area 42 is cleared. Thereafter, the person in charge of operation B inputs the issue key 26. As a result, the printer 14 sequentially prints out the contents of the save buffer 43 corresponding to the person in charge code [2] on receipt paper, and a receipt 52 as shown in FIG. 11 is issued.

Next, the operation manager C who has completed the product assortment inputs the manager key 27c, and then inputs the current total key 23. As a result, the responsible person code [3] of the responsible person table 40
After the instruction flag F3 corresponding to this person code [3] is set to "1" and the remaining instruction flags F1, F2, F4 and F5 are reset to "0", the totalizer area 42 corresponding to this responsible person code [3] is The content [400] is displayed on the display 12 as the total amount. Further, the total amount is stored as registered total data in the save buffer 43 corresponding to the responsible person code [3], and the totalizer area 42 is cleared. Thereafter, the person in charge of operation C inputs the issue key 26. As a result, the printer 14 prints the responsible person code [3].
The contents of the save buffer 43 corresponding to the above are sequentially printed out on receipt paper, and a receipt 53 as shown in FIG. 12 is issued.

[0029] When the person in charge of operation who has received payment from the previous customer registers the ordered product of the next customer, the save buffer 43 corresponding to the person in charge of operation is once cleared by the first product registration of the next customer. This clearing process is performed regardless of whether a receipt has been issued to the previous customer.

As described above, according to this embodiment, the interrupted operator can perform the tightening operation before the operator who has registered the interruption can perform the tightening operation. In this case, a normal receipt can be issued to both the customer who was interrupted and the customer who interrupted. Therefore, even if you use interrupt registration frequently, there will be no wasted waiting time, and the inconvenience of not being able to issue a receipt will not occur, so business efficiency can be improved, sufficient serviceability can be ensured, and sales can be improved. We can expect this to be promoted.

[0031] Furthermore, since the issuance key 26 is provided as an instruction key to instruct the issuance of a receipt, and the issuance of a receipt is optional, receipts are not issued to customers who do not need a receipt, thereby increasing work efficiency. It is also possible to increase it.

Note that it is also possible to use the current total key 23 as an instruction key for instructing the issuance of a receipt. The current key processing in this case is shown in FIG. That is, when the content of the totalizer area 42 corresponding to the operator in charge whose instruction flag is set to "1" is other than "0", the content is displayed as the total amount on the display 12 and also as the registered total data. It is written to the save buffer 43 for each person in charge. Thereafter, the totalizer area 42 is cleared and the contents of the save buffer 43 are printed out on receipt paper to issue a receipt. By doing this, in a store that always issues receipts to each customer, the waste of operating the issue key 26 can be eliminated, and operability can be improved.

In addition, in the embodiment described above, the person in charge keys 27a to 27e are shown as a means for instructing the person in charge of inputting product sales data or closing the registration operation, but similarly to the mode switch 6, the key can be used for switching operations. It is also possible to instruct the person in charge of operation by providing a switch that allows the person in charge of operation to set the switchable range. In addition, various modifications can be made without departing from the gist of the present invention, such as providing the electronic cash register of this embodiment with a data communication function to a host model and using it as a POS (point of sale) terminal. Of course.

[0034]

[Effects of the Invention] As described in detail above, according to the present invention, even if an operator in charge registers an interrupt while another operator in charge registers, the interruption occurs before the operator closes the registration. To provide an electronic cash register which can be operated by a person in charge of operation, can issue a receipt to each customer regardless of whether there is an interruption, can surely improve business efficiency, and can ensure sufficient serviceability.
