Description

The present invention relates to a POS system and a program .

  2. Description of the Related Art Conventionally, a POS system including a store computer, a POS terminal (product sales data processing device), and the like has been introduced to manage product sales data in supermarkets, convenience stores, and the like. The POS terminal is used with a drawer for storing sales and change. In such a POS system, when the store is opened, change reserves are inserted into the drawer, and when the store is closed, the entire amount of money in the drawer is collected, and the amount stored in the drawer is subtracted from the amount of change reserves that were inserted at the time of opening. Is calculated as the amount of money put into the drawer during business hours, and the entire amount is collected and managed in comparison with the sales amount recorded in the POS system.

  In recent years, change machines are often used in place of drawers that temporarily store money that is connected to a POS terminal. The change machine has not only a function of automatically paying out necessary change according to a command from the POS terminal, but also a function of counting the amount of money stored therein. There has been an invention relating to a POS system that manages deposits and withdrawals at the time of merchandise sales data processing using information on the amount of money in the change machine grasped by such a change machine (for example, Patent Document 1).

  When a change machine with a function to count the amount of money is used, when the store is closed, the money in the change machine is left without being collected in full, and the remaining money in the change machine is used as the next day's change reserve. It becomes possible to operate the POS system in the operation mode.

JP-A-10-198866

  When the change machine is operated in the remaining operation mode, it is not necessary to collect all the money in the change machine when the store is closed and to insert the change reserve before opening the store the next day, as in the case of the full recovery operation. In other words, there is no money in / out operation when the store is closed and when the store is opened. As a result, mistakes in counting the amount of money stored in the change machine, money collection mistakes, illegal cash exploitation, etc., associated with the taking in and out of money are less likely to occur.

  However, when the change operation is performed with a change machine, the work of collecting the full amount of money at the time of closing and the input of change reserve at the time of opening, which was performed at the time of the full recovery operation, becomes unnecessary. There is no opportunity to check the amount of money that has been put into the bank and the amount of change reserve that is put into the change machine when the store opens. For this reason, it is necessary to check the amount stored in the change machine at the time of opening the store and input it to the POS terminal anew, despite the remaining operation.

  Also, even if the change machine is left behind, it cannot be stored in the change machine during business hours, so some of the money stored in the change machine can be collected in a safe, etc. In addition to merchandise transactions, there is still work to handle money, such as replenishing money of denominations. Since the amount of money withdrawn / withdrawn in such an operation does not accompany the commodity transaction, it is not recorded in the POS terminal or POS system. Therefore, when the cashier collects money from the change machine or adds money to the change machine, the cashier needs to input the money amount collected or replenished to the POS terminal and record it in the POS system. Also at this time, there is a possibility that an input error of the amount to be input to the POS terminal may occur, or money may be illegally exploited by intentionally changing the amount.

  In addition, when the POS system is operated in a floating cashier system in which the cashier operating the POS terminal changes during business hours, the deposit and withdrawal of money stored in the change machine each time the individual cashier signs on to the POS terminal. Management is also required. Even if the operation mode of the residual operation is used, the trouble of confirming the coincidence / inconsistency between the sales amount of each cashier and the amount of money handled by the cashier before and after the cashier signs on is not omitted.

  As mentioned above, even if a change machine equipped with a function to grasp the amount of money stored is introduced, it is not possible to grasp the deposit / withdrawal status of money in the change machine, it is not possible to switch to the remaining operation, and the full collection operation remains The POS system was often operated.

An object of the present invention is to provide a POS system and a program that facilitate the introduction of the operation mode of the remaining operation in order to improve the efficiency of money deposit / withdrawal management.

[Output processing]
FIG. 12 is a flowchart showing the flow of output processing for outputting management data to the output unit (printer PL) for each POS terminal 2. FIG. 13 is a flowchart showing the flow of output processing for outputting management data for each cashier to the output unit (printer PL). Hereinafter, description will be given according to the flowcharts shown in FIGS.

  First, a case where management data for each POS terminal 2 is output will be described with reference to FIG.

  When an operation command for outputting management data for each POS terminal 2 is input from the input unit 8 to the information processing unit 201 of the POS terminal 2, the management data 302 stored in the RAM 204 is sorted in the order of the operation time 303 (ST61). ), The sorted management data 302 is transmitted to the printer PL (ST62).

  As a subsequent process, the information processing unit 201 performs a display asking whether to clear the management data 302 stored in the RAM 204 of the POS terminal 2 on the cashier display unit 9, and clears the management data 302 from the input unit 8. Judgment of whether or not to do is accepted (ST63). When the determination to clear the management data 302 is input to the input unit 8 (Y in ST63), the information processing unit 201 clears the management data 302 stored in the RAM 204 (ST64) and ends the output process. On the other hand, when the determination not to clear the management data 302 is input to the input unit 8 (N in ST63), the information processing unit 201 ends the output process without clearing the management data 302 stored in the RAM 204. To do.

  Note that the operation command to output the management data 302 for each POS terminal 2 as described above is received not only by each POS terminal 2 but also by receiving an input of a cash register No. from the keyboard 411 of the POS management server 3. The management data 502 including the input cash register No. is extracted from the management data 502 recorded in the HDD 406, and the information processing unit 401 of the POS management server 3 sorts the extracted management data 502 based on the operation time 303. May be output from the printer PL.

  Next, a case where management data is output for each cashier will be described with reference to FIG.

  When the information processing unit 401 of the POS management server 3 receives an input of the cashier ID 304 from the keyboard 411 and an operation command for outputting the management data related to the input cashier ID 304 is input, the management data stored in the HDD 406 is stored. After the management data 502 having the input cashier ID 304 is extracted from 502 (ST71), the extracted management data 502 is sorted in the order of operation time 303 (ST72).

  As a subsequent process, the information processing unit 401 calculates the cashier-specific change machine input amount 507 (see FIG. 15) and the excess / deficiency amount 508 (see FIG. 15), and adds them to the management data 502 (ST73). The cashier input amount 507 for each cashier is the total of the sales amount of the transaction products registered in the POS terminal 2 when each cashier signs on the POS terminal 2 and performs the product transaction. Management data in which the operation instruction code 305 is “sign-off” in the management data 502 including the session ID 503 issued before the time when the session ID 503 of the management data 502 is issued in the change amount input 505 for each session. The calculation is performed by adding the change amount 505 for each session, which is 502. The excess / deficiency amount 508 is calculated by subtracting the cashier sales amount 506 from the cashier change amount input amount 507.

As a subsequent process, the information processing unit 401 transmits management data to which the sales amount by cashier is added to the printer PL (ST74).
[Action]
By using the POS system 1 that executes the processing as described above, it becomes possible to improve the efficiency of money deposit and withdrawal management.

  That is, the POS terminal 2 and the change machine 6 constituting the POS system 1 are connected to each other so as to be able to communicate with each other, and when the information processing unit 201 of the POS terminal 2 falls, The storage amount of money stored in the change machine 6 is stored in the RAM 204 as the storage unit as the “storage amount at the time of falling”. Then, the information processing unit 201 of the POS terminal 2 also executes a storage amount acquisition process at the time of startup, and stores the storage amount of money stored in the change machine 6 as “storage amount at startup” in the RAM 204 which is a storage unit. Remember. Then, the information processing unit 201 of the POS terminal 2 compares the storage amount at the time of start-up with the storage amount at the time of startup, and determines whether or not they match. That is, since the RAM 204 of the POS terminal 2 grasps the amount stored in the change machine 6 at the time of closing and opening the store, the store is closed even if the remaining operation without collecting the money in the change machine 6 is performed at the time of closing. It is guaranteed that the amount of money stored does not change between the time of opening and the time of opening.

  As described above, when the POS system 1 of the present invention is used, the POS terminal 2 and the change machine 6 work together, and when the store is closed, the amount of money stored in the change machine 6 is grasped by the information processing unit, and the store opens. Since it is determined whether or not the amount of money stored in the change machine 6 at the time is coincident, management of the change machine during the closing time becomes easy, and the efficiency of money deposit / withdrawal management in the POS system is improved.

  Further, in the POS terminal 2 constituting the POS system 1, every time an operation command is input from the input unit 8, the money storage amount stored in the change machine 6 is stored in the RAM 204 as an operation storage amount. Management data is created by associating the time storage amount with information such as operation time and cashier ID, and stored in the storage unit. Further, the POS management server 3 constituting the POS system 1 receives management data created by the POS terminal 2 every time an operation command is input from the input unit 8 for each cashier, and the received management data for each cashier. to manage.

  As described above, by using the POS system 1 of the present invention, the POS terminal 2 and the change machine 6 are interlocked even during business hours, and the information storage unit always knows the money stored in the change machine 6. Therefore, in addition to managing the change machine during the closing time, it becomes easy to manage the change and payment of the change machine during the business hours, and the efficiency of money management in the POS system is further improved.

  Further, the management data managed by the POS terminal 2 and the POS management server 3 in this way is sorted in time series, and then the sales records managed by the POS system 1 and the money put into the change machine 6 are collected. Is output from the printer PL, which is an output unit, so that it can be compared with the amount of money input.

  14 and 15 are schematic diagrams illustrating an example of management data output from the printer PL. First, an example of management data for each POS terminal 2 output from the printer PL will be described with reference to FIG.

  The management data 302 for each POS terminal 2 output from the printer PL is output as a tabular report in the form shown in FIG. 14 on A4 size paper. In the upper left of the output table C1, a cash register No. 504 corresponding to the POS terminal 2 and a date DT on which the management data 302 is created by the POS terminal 2 are described.

  The configuration of Table C1 will be described.

  Each row of the table C1 stores management data created by the POS terminal 2. The table C1 is configured by positioning the operation time 303 constituting the management data 302 in the leftmost column and arranging the management data 302 stored in each row in the order of the operation time 303.

  In the table, each management data 302 includes an operation time 303, a cashier ID 304, an operation command code 305, an operation storage amount 306, a breakdown by money 307, a recovery amount 308, a replenishment amount 309, a cumulative transfer amount 310, and change from the left. The machine input amount 311, the POS terminal sales amount 312, and the excess / deficiency amount 313 are arranged in this order.

  As a result of the management data 302 being arranged in this way, among the management data 302 positioned at the top row of the table C1, the operation storage amount 306 is the storage amount stored in the change machine 6 when the cash register is opened. It shows the amount of money stored. Also, among the management data 302 positioned at the bottom row of the table C1, the change machine input amount 311, the POS terminal sales amount 312 and the excess / deficiency amount 313 are transferred to the change machine 6 by the product transaction performed at the POS terminal 2. The figure shows the amount of money inserted, the amount of sales recorded in the POS terminal 2, and the difference between the amount of money inserted and the amount of sales.

  Further, as shown in FIG. 14, by calculating and displaying the total amount of the collected amount 308 and the replenishment amount 309 in the lower row of the management data 302 positioned at the bottom row of the table C1, the commodity transaction It becomes easy to grasp the fluctuation state of the money moved from the change machine 6 by the money collection process and the money replenishment process other than the above.

  Next, an example of management data for each cashier output from the printer PL will be described with reference to FIG.

  Similarly to the management data for each POS terminal 2, the management data 502 for each casher output from the printer PL is also output as a tabular report as shown in FIG. In the upper left, a casher ID 304 and a date DT on which the management data 502 is stored in the POS management server 3 are described.

  The configuration of Table C2 will be described.

  The table C2 is configured by arranging the management data 502 formed by adding the session ID 503, the cash register No. 504, and the like to the management data 302 created by the POS terminal 2 in the order of the operation time 303 in each row.

  In the table C2, each management data 502 includes, from the left, a session ID 503, an operation time 303, an operation command code 305, a cash register No 504, an operation storage amount 306, a breakdown by money 307, a collection amount 308, a replenishment amount 309, and cumulative movement An amount 310, a change machine input amount 505 by session, a change machine input amount 507 by cashier, a sales amount 506 by cashier, and an excess / deficiency amount 508 are arranged in this order.

  As a result of the management data 502 being arranged in this manner, the sales amount 506 for each cashier calculated for each cashier from the sales data stored in the POS management server 3 and the change of the POS terminal 2 when the cashier performs a commodity transaction. The change amount 507 of the change machine by cashier, which is the sum of the amounts of money inserted into the machine 6, and the excess / deficiency amount 508 which is the difference between the sales amount 506 by cashier and the change amount 507 of change machine by cashier are at the right end of Table C2. These are arranged and further displayed in time series.

  That is, if the POS system 1 of the present invention is used, the amount of money stored in the change machine 6 and the sales amount managed by the POS system 1 at that time are compared for each POS terminal 2 and each cashier. It is possible to output a report in which management data that can be processed is arranged in time series.

  As described above, the POS system 1 according to the present invention can grasp the entire state of money deposit / withdrawal in the POS system 1 using the output report, thereby improving the efficiency of money deposit / withdrawal management in the POS system 1. Is further planned. For example, the cashier illegally takes out money from the change machine 6 by tracking the difference between the sales amount of each cashier from the time of opening the store to the closing time and the amount actually inserted into the change machine 6 in order of operation time. It becomes possible to analyze the act and whether the cashier has forgotten to insert money into the change machine 6 or the like.

  Further, by performing the remaining operation using the POS system 1 of the present invention, the cashier's operation for checking the amount of money that the cashier had to perform at the time of closing and opening of the store becomes unnecessary. The data input operation to the POS terminal 2 accompanying the collection of money and the replenishment of money to the change machine 6 becomes unnecessary. That is, it can be said that the POS system 1 of the present invention is a system in which the residual operation is easily introduced.
