Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a POS system in which all electronic cash registers automatically start inspection operations at a predetermined time regardless of the set operations. Regarding the system.

[Technical backbone of the invention and its problems 1 When it is necessary to arrange a large number of electronic cash registers, such as in department stores and supermarkets, each electronic cash register is connected in a closed loop with a transmission path, and each electronic cash register is A POS system is used that centrally manages sales data of products registered for sale at a cash register.

When performing sales operations using such a POS system, each cashier sets the operation mode of the electronic cash register (hereinafter abbreviated as register) to the registered operation mode, and then sets the sales data such as the sales amount and department code of the sold products. When the user manually presses a registration key such as a number key or a department key provided on the keyboard, the inputted sales data is stored in a file n1, a collection of departmental files, etc., provided in the storage section. When a certain amount of products have been sold and the cashier wants to check the collected sales data of the products sold so far, the cashier should set the business mode to inspection mode and use the aggregated data registered in the departmental file ( Inspection data) is output.

However, such a POS system has the following problems. In other words, when performing inspection work at each register as described above, the cashier must temporarily interrupt sales registration work, switch the business mode to inspection mode using the control key, and input an inspection command using the key operation. Therefore, if all registers making up the POS system were to be inspected at the same time at a predetermined time, sales registration operations would be suspended and the sales registration operations at each register (J) would be suspended before the inspection time. Therefore, there was a problem that not only the efficiency of the sales registration work decreased, but also the burden on the carriage t'- increased.Furthermore, the sales registration work should not be interrupted during the inspection work. If this happens, the customer will be forced to wait during that time, resulting in a decline in service to the customer.

[Objective of the Invention] The present invention has been made based on the above circumstances, and its purpose is to automatically collect all electronic cash at a predetermined time regardless of the set business. To provide a POS system that can reduce the burden on a cashier, obtain accurate inspection data, and improve service to customers by allowing a register to automatically start inspection operations.

[Summary of the Invention] In the POS system of the present invention, one electronic cash register among the plurality of electronic cash registers constituting the POS system is used as a master electronic cash register, and this electronic cash register has the following functions: A time memory that stores a time element indicating the time to execute inspection operations on all electronic cash registers at the same time, and automatically issues an inspection operation start command to all electronic cash registers at the time stored in this time memory. In addition, each electronic cash register is equipped with a means to send out the total data registered in each total file to an external center file in response to the input of the above-mentioned inspection service start command, regardless of the setting operation. We are trying to provide a means to send and register them.

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

FIG. 1 is a block configuration diagram showing a POS system according to an embodiment, in which a plurality of general electronic cash registers 1 (
(hereinafter abbreviated as register) and one master electronic cash register 2 (hereinafter abbreviated as master register)
and the control section 3 are connected in a closed loop through one transmission line 4.

Each of the registers 1 and the master register 2 stores sales data such as the sales amount of products sold to customers and department codes on the keyboard (enters them using registration keys such as the assigned number key and the -1 department key). The control section 3 controls each register 1 and the master register 2. The control section 3 controls each register 1 and the master register 2.

Note that a floppy disk storage device 5 is externally connected to the master register 2 as a center file.

FIG. 2 is a block diagram showing the master register 2. A CPU (Central Processing Unit) 6 includes an arithmetic circuit, a command register, etc., and performs various functions based on manual information from the control keys 7 and keyboard 8. In addition to performing arithmetic processing, it also stores fixed data of programs for each business mode such as [registration], [inspection], [accounting], and [setting] via address bus 9, data pathco 0, and control signal line 11. The ROM 12 and the RAM 13 for storing the keyed sales data of each product are operated. and 6- a control circuit 14 for the floppy desk storage device 5, a keyboard input circuit 15 to which key signals from the keyboard 8 are input, a control key input circuit 16 to which each business mode command signal from the control keys 7 is input; A display control circuit 18 that sends a display drive signal to the display unit 17 that displays the sales amount, department code, total amount, etc., a printer control circuit 20 of one printer that prints the sales amount, combined amount, etc. to the cash register 1. I10 interface circuits 21 connected to the transmission line 4 are connected to the CPU 6 via the data bus 10 and control line 11, respectively.

As shown in FIG. 3, the RAM 13 stores product sales data entered by key operations of registration keys such as numeric keys and department keys provided on the keyboard 8, including sales points and sales for each department code. In addition to the departmental file RA1 that cumulatively stores each amount, a time table RA2 is formed as a time memory that stores a time element indicating a time 2 at which all registers including the master register 2 are to be inspected at the same time. Teru. This time table R
A2 is provided with an area RAS for storing N table numbers and an area RA4 for storing the set time until the time when inspection work is started for each table number. Furthermore, the RAM 13 includes a table variable 7 area RA5 that temporarily stores the table number under measurement of the time table RA2;
Similarly, time measurement T that temporarily stores the setting time of area RA4.
Area RA6, set time it ill! M indicating that it is in the l.

An area RA7 for storing FLAG is formed.

Each register 1 other than the master register 2 has almost the same configuration as the master register 2, but the floppy disk storage device 5 and the control circuit 14 are not provided, and the R
AM13 is provided with only a departmental file RA1. Further, the control unit 3 is provided with a tally file 22 that stores the settlement data of all the registers 1.2.

When setting in the time table RA2 how many hours after the power is turned on in the master register 2 to have all the inspection operations performed all at once, it is carried out based on the procedure shown in FIG. That is, the user operates the control key 7 to change the business mode to the [setting] mode. Thereafter, by operating the numeric keys and function keys provided on the keyboard 8, the table number of area RA3 and the setting time of area RA4 are input in the order of the table numbers. When all data input is completed, a key indicating completion of setting, such as a current total key, is pressed to end the setting work.

When the above setting work is completed, the cashier sets the control key 7 to the [registration] mode to start product sales registration. In this state, the CP of master register 2
U6 is configured to send an inspection service start command to the control unit 3 via the transmission line 4 based on the flowchart in FIG.

That is, this inspection start routine is activated by the interrupt of the clock signal of the CPU 6, for example every 20 m5ec, and when the control key 7 is set to the [registration] mode, first the time piece 1 measurement of R9-AM13 is started. Initialize the value (T) of area RA6 and the value (Z) of table variable area RA5 (T-0,
Z=1), waits for an interrupt of the clock signal at Pl. When an interrupt signal is input at Pl, R2 is input.
M in area RA7 of AM13.

Check whether FLAG is set to 1, and if it is not 1, select the area RA3 specified by table variable 7 of area RA5.
The setting time of the area RA4 corresponding to the number is stored in the time measurement T area RA6, and M and FLAG of the area RA7 are set to 1. Thereafter, the time T stored in area RA6 is decreased by 1. Then, in R3, it is confirmed that the above-mentioned time T is not zero, and the process returns to P1 to have the next clock signal interrupt.

If M and FLAG are set to 1 in R2, the time T in area RA6 is subtracted by 1 because the set time is already being measured. When the time in the area RA6 becomes zero at R3, an inspection start command is sent to the control unit 3 via the I10 interface circuit 21 and the transmission line 4. after that,
Clear M of area RA7 to FLAG@O, area RA5
Q10 - Advance pull variable 7 by 1. After confirming at P4 that the table variable 7 does not exceed the set number N of table numbers, the process returns to P1. When the table variable exceeds N at P4, it is determined that all inspection start commands have been sent to the control unit 3, and this program is ended.

Each time the control unit 3 receives each inspection start command from the master register 2, the control unit 3 sends these inspection start commands to the master register 2.
The data is sent to each register including the data via the transmission line 4. All the registers 1.2 start their own inspection work upon receiving the inspection start command. Then, the total data of the department files, that is, the inspection data, is once sent to the master register 2 via the control section 3. master register 2
The received inspection data is stored in the floppy disk by the floppy disk device 5 via the control circuit 14.

In this case, in order to execute inspection work even though registration work is in progress in each register, 1.2, the timing to search departmental file RA1 for registration work and the above departmental file for inspection work are required. The timing of searching for file RA1 is shifted. Specifically, while one is searching, the other is on standby. By doing so, it is possible to execute sales registration work and inspection work at the same time.

In a POS system configured in this way, for example, if all registers 1.2 are to be inspected at the same time 3 hours, 5 hours, and 7 hours after the start of the registration process,
Set the business mode of the master register λ to the [setting] mode in advance, and set the time table RAI according to the procedure shown in Figure 4.
What is necessary is to set 3 hours, 2 hours, and 2 hours in area RA4 corresponding to number 1.2.3 of area RA2. With this setting, the master register 2 automatically sends an inspection start command to the control unit 3 when two hours have elapsed since the start of the sales registration business. As a result, an inspection start command is sent from the control section 3 to all the registers 1.2, and the inspection data of all the registers 1.2 are stored in the floppy disk of the floppy disk device @5 of the master register 2. Similarly, inspection data of all registers 1.2 after 5 hours and 7 hours are stored in the floppy disk of master register 2.

In a POS system like this, each register 1.
Even if 2 is in the process of registering sales, the inspection data for all registers 1 and 2 will be automatically obtained at the time preset in master register 2, so each cashier will be able to carry out the inspection himself. Since there is no need for this, you can concentrate on sales registration work, and the work efficiency of sales registration work can be improved. It is also possible to reduce the burden on the cashier. Furthermore, since there is no need to interrupt sales registration work for inspection work, customers are not kept waiting, and service to customers can be improved. Furthermore, since the inspection work time is accurate, the inspection data obtained will also be accurate.

Note that the present invention is not limited to the embodiments described above. That is, the RAM 23 of master 13-register 2 may be formed as shown in FIG. This RAM
In 23, there is an area 11 R for storing the time at which inspection work is to be started corresponding to each table number in the time table RA2.
A 8 is provided. Further, a time measurement T area RA9 is formed to temporarily store the set time of this area RAS. Note that the master register 2 is provided with a clock circuit that measures the time of day. Therefore, the CP of the master register 2 in the POS system of this embodiment is
U6 is configured to send an inspection start command to the control unit 3 according to the flowchart shown in FIG. In this flowchart, each time a clock signal from the CPU 6 interrupts, the current time TM is read from the clock circuit and compared with the set time T stored in the area RA9, and when these values become equal, the control unit 3 The inspection start command is sent to the With a POS system configured in this way, 10
What is necessary is just to set the inspection time of the day, such as 13:00, 13:00, 15:00, in area RAS of time table RA2 of RAM23.

14- Even with a POS system having such a configuration, effects similar to those of the above embodiment can be obtained.

[Effects of the Invention] As explained above, according to the present invention, all electronic cash registers including the master electronic cash register automatically operate at the time set in advance on the master electronic cash register, regardless of the set business mode. We are planning to start inspection work in due course. Therefore, it is possible to reduce the burden on the cashier, obtain accurate inspection data, and further improve customer service.
