Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a POS in which all electronic cash registers automatically start inspection work at a predetermined time regardless of the set work. Regarding the system.

[Technical Background of the Invention and Problems Thereof] When it is necessary to arrange a large number of electronic cash registers such as in a department store or a supermarket, each electronic cash register is connected in a closed loop through a transmission line, and each electronic cash register is connected. A POS system is used that centrally manages sales data of products registered for sale at a register.

When performing sales operations in 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 the sales data such as the sales amount of the product to be sold and the sales data of the department code are input to the keyboard. When the key input is performed with the registration keys such as the numeric keypad and the department key provided in, the input sales data is stored in a totaling file such as a departmental file provided in the storage unit. Then, when confirming the totalization of the sales data of the products that have been sold at the time when a certain amount of products are sold, the cashier sets the operation mode to the inspection mode, and the totalized data ( Inspection data) is output.

However, such a POS system has the following problems. That is, when performing inspection work at each register as described above, the cashier must suspend the sales registration work, switch the operation mode to the inspection mode with the control key, and input the inspection command by key operation. Therefore, if all the cash registers of the POS system are to be inspected at a predetermined time all at once, each cashier must suspend the sales registration operation and wait before the inspection time. It was Therefore, there is a problem that not only the work efficiency of the sales registration work is lowered but also the burden on the cashier is increased. Further, since the sales registration work must be suspended during the inspection work, the customer is kept waiting during that time, and the service for the customer is deteriorated.

In addition, the time and interval at which the inspection work is carried out are determined by the store side depending on the situation of customers entering. For example, in a store that has a large number of customers at the time of opening, it is desirable to perform the first inspection in a short time after the opening and then perform the second inspection at intervals. On the other hand, in a store with a low number of customers at the time of opening, even if the first inspection is performed in a short time after opening, meaningful data cannot be obtained as aggregated data.

[Object of the Invention] The present invention has been made based on such a situation, and an object thereof is to set a plurality of times arbitrarily set according to the situation of the store regardless of the set business. In that case, all electronic cash registers will automatically start inspection work, thereby providing a POS system that can reduce the burden on the cashier, obtain accurate inspection data, and improve the service to customers. Especially.

[Outline of the Invention] In the POS system of the present invention, one electronic cash register of a plurality of electronic cash registers constituting the POS system is used as a master electronic cash register, and this electronic cash register is used for all electronic cash registers. On the other hand, a time table that stores time elements indicating a plurality of times at which inspection work is executed simultaneously corresponding to a series of table numbers, time element setting means that sets the time elements in this time table in order of table number, A table variable area that stores the table number during measurement of the table, a time element measurement area that stores the time element during measurement of the time table, a flag area that sets a flag when measuring the time element, and a fixed interval A means for checking the flag area each time an interrupt signal is input, and a flag When reset is confirmed, the time element corresponding to the table number in the table variable area is read from the time table, stored in the time element measurement area, and a flag is set in the flag area. It is determined whether it is the time of the time element stored in the area, and if it is that time, an inspection work start command is automatically sent to all the electronic cash registers, the flags in the flag area are reset, and the table variable area In addition to providing a means to update the table variable to the next table number, in response to the input of the above inspection work start command to each electronic cash register, the totalized data registered in each totalization file is set regardless of the setting work. A means is provided for transmitting and registering to a center file provided outside.

Embodiments of the Invention Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a POS system according to an embodiment, which includes a plurality of general electronic cash registers 1 (hereinafter abbreviated as registers) and one master electronic cash register 2 (hereinafter abbreviated as master register). And the control unit 3 are connected in a closed loop by one transmission unit 4.

The register 1 and the master register 2 are used to enter sales data such as the sales amount of a product sold to a customer and a department code using a numeric key provided on the keyboard and a registration key for the department key, and store them in an internal storage unit. It is to be registered in the provided file for each department, and the control unit 3 controls each register 1 and the master register 2. The master register 2 is externally connected to a floppy disk storage device 5 as a center file.

FIG. 2 is a block diagram showing the master register 2. The CPU (central processing unit) 6 has an arithmetic circuit, a command register, etc. built-in, and various types of CPUs based on input information from the control key 7 and the keyboard 8. Performs arithmetic processing and stores fixed data of a program in each business mode such as [Registration], [Check], [Settlement], and [Setting] via the address bus 9, the data bus 10, and the control signal line 11. The ROM 12 and the RAM 13 that stores the sales data of each merchandise keyed in are operated. Also, the control circuit 14 and the keyboard 8 of the floppy desk storage device 5 are described.
A keyboard input circuit 15 to which a key signal from
Control key input circuit 16 to which each operation mode command signal from control key 7 is input, display control circuit 18 that sends a display drive signal to display unit 17 that displays sales amount, department code, total amount, etc., sales to receipt Amount of money,
The printer control circuit 20 of the printer 19 for printing the total amount of money and the I / O interface circuit 21 connected to the transmission path 4 are the data bus 10 and the control line 11, respectively.
Is connected to the CPU 6 via.

In the RAM 13, as shown in FIG. 3, the sales data of the products input by the key operation of the registration keys such as the numeral keys and the department keys provided on the keyboard 8 are classified according to the department code, and the sales number and sales. In addition to the department-specific file RA1 for accumulatively storing the amount of money, a time table RA2 is formed as a time memory for storing a time element indicating the time at which all the registers including the master register 2 are to be inspected at the same time. ing. This time table RA2 has an area RA3 for storing N table numbers.
An area RA4 for storing the set time until the time when the inspection work is started is provided for each table number.
Further, the RAM 13 has a table variable Z area RA for temporarily storing the table number of the time table RA2 during the measurement.
5, a time measurement T area RA6 for temporarily storing the set time of the area RA4, and M.M. An area RA7 for storing FLAG is formed.

Each of the registers 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
Only the department file RA1 is provided in the AM13. Further, the control unit 3 is provided with a totalization file 22 for totalizing the adjustment data of all the registers 1 and 2.

Therefore, when the time table RA2 is set to indicate how many hours after the power is turned on in the master register 2, the inspection work is carried out in accordance with the procedure shown in FIG. That is, the control key 7 is operated to set the business mode to the [setting] mode. After that, the table number of the area RA3 and the set time of the area RA4 are input in the order of the table numbers by operating the numeric keys provided on the keyboard 8 and the function keys. When all data has been input, the setting operation is finished by pressing a key indicating the end of setting such as a current key.

When the above setting work is completed, the cashier sets the control key 7 to the [registration] mode and starts the product sales registration. In this state, CP of master register 2
Based on the flowchart of FIG. 5, U6 is configured to send an inspection work start command to the control unit 3 via the transmission line 4. That is, this inspection start routine is
It is designed to operate by a clock signal interrupt of U6, for example, every 20 msec.
Is set to the [registration] mode, first, the value (T) of the time measurement area RA6 of the RAM 13 and the table variable area RA5
After initializing the respective values (Z) (T = 0, Z = 1), wait for the clock signal interrupt at P1. When an interrupt signal is input at P1, the M.M.A. of area RA7 of RAM 13 is input at P2. It is checked whether FLAG is set or reset, that is, whether it is set to 1, and if it is not 1, the setting time of the area RA4 corresponding to the number of the area RA3 designated by the table variable Z of the area RA5 is set to time. It is stored in the measurement T area RA6 and the M.T. FL
Set AG to 1. After that, the time T stored in the area RA6 is reduced by one. Then, after confirming that the time T is not zero at P3, the process returns to P1 and waits for the interrupt of the next clock signal.

M.P.2 If FLAG is set to 1, the time T of the area RA6 is reduced by 1 because the set time is already being measured. When the time in the area RA6 becomes zero at P3, the inspection start command is sent to the control unit 3 via the I / O interface circuit 21 and the transmission path 4. afterwards,
M.D. of the area RA7. FLAG is reset, that is, cleared to 0, and the table variable Z in the area RA5 is advanced by 1.
In P4, the table variable Z is the set number N of table numbers.
After confirming that it has not exceeded, return to P1. When the table variable exceeds N at P4, it is determined that the sending of all the inspection start commands to the control unit 3 is completed, and this program is ended.

Each time the control unit 3 receives each inspection start command from the master register 2, these inspection start commands are sent to the master register 2
Is transmitted to each register including the above via the transmission path 4. All the registers 1 and 2 start their own inspection work at the time of receiving the inspection start command. Then, the totalized data of the file for each department, that is, the inspection data is once sent to the master register 2 via the control unit 3. The master register 2 stores each received inspection data in the floppy disk in the floppy disk device 5 via the control circuit 14. In this case, in order to execute the inspection work even though the registers 1 and 2 are in the registration work, the timing for searching the divisional file RA1 for the registration work and the above-mentioned divisional file for the inspection work The timing for searching RA1 is shifted. Specifically, while one is searching, the other is waiting. By doing so, it is possible to simultaneously execute the sales registration work and the inspection work.

In the POS system configured as described above, for example, in the case where the inspection work of all the registers 1 and 2 is performed all at once after 3 hours, 5 hours, and 7 hours after the start of the registration work,
The work mode of the master register 2 is set to the [setting] mode in advance, and the time table RA1 is set according to the procedure of FIG.
3 hours, 2 hours, and 2 hours may be set in the area RA4 corresponding to the numbers 1, 2, and 3 of the area RA2. With this setting, the master register 2 automatically sends an inspection start command to the control unit 3 when two hours have passed after the start of sales registration work in the master register 2. As a result, the control unit sends an inspection start command to all the registers 1 and 2, and the inspection data of all the registers 1 and 2 is stored in the floppy disk of the floppy disk device 5 of the master register 2. Similarly, the inspection data of all the registers 1 and 2 at the time when 5 hours have passed and at the time when 7 hours have passed are stored in the floppy disk of the master register 2.

In such a POS system, each register 1, 2
Even if the sales registration work is in progress, the inspection data of all the registers 1 and 2 is automatically obtained at the time set in advance in the master register 2, so each cashier needs to carry out the inspection work by himself / herself. Since there is no such thing, it is possible to concentrate on the sales registration work and improve the work efficiency of the sales registration work. It is also possible to reduce the burden on the cashier. Further, since it is not necessary to suspend the sales registration work for the inspection work, the customer can be improved without waiting for the customer.
Moreover, since the inspection work time is accurate, the obtained inspection data is also accurate.

The present invention is not limited to the above embodiment. That is, as shown in FIG. 6, R of the master register 2 is
The AM 23 may be formed. In the RAM 23, the time table RA2 is provided with an area RA8 for storing the time when the inspection work is started corresponding to each table number. Further, there is formed a time measurement T area RA9 for temporarily storing the set time of this area RA8. The master register 2 is provided with a clock circuit that measures the time of day. Therefore, the CPU 6 of the master register 2 in the POS system of this embodiment is configured to send an inspection start command to the control unit 3 according to the flowchart of FIG. In this flow chart, every time the clock signal is interrupted from the CPU 6, the current time TM is read from the clock circuit and compared with the set time T stored in the area RA9.
An inspection start command is sent to the control unit 3 when these values become equal. P configured in this way
In the case of the OS system, the inspection time of one day such as 10:00, 13:00, and 15:00 may be set in advance in the area RA8 of the time table RA2 of the RAM 23.

Even with the POS system having such a configuration, the same effect as that of the above-described embodiment can be obtained.

[Effects of the Invention] As described above, according to the present invention, all the electronic devices including the master electronic cash register are reached at a plurality of times arbitrarily set in the master electronic cash register in advance regardless of the set business mode. The cash register automatically starts inspection work. Therefore, it is possible to reduce the burden on the cashier, obtain accurate inspection data suitable for the situation of the store, and further improve the service to customers.
