Description

Description: TECHNICAL FIELD The present invention relates to a sales data processing device capable of transmitting / receiving data to / from a data collecting device.

[Prior Art] In recent years, systemization of electronic registers has progressed, and each time an electronic register (sales data processing device) on the slave side inspects the electronic register (data collection device) on the master side using online or inline. , All the sales total data of the sales data processing device is transmitted and totaled by the data collection device.

[Problems to be Solved by the Invention] However, transmitting all the sales total data for each inspection requires a long transmission time, a high running cost of a telephone line, and the cost thereof is enormous. Therefore, it is conceivable that the operator may reduce the running cost of the telephone line etc. by extracting and transmitting only the updated sales total data to a separate file for each inspection, but it is very troublesome to create a separate file. It will take.

An object of the present invention is to make it possible to easily output only updated data each time it is output.

[Means for Solving the Problems] Means of the present invention are as follows.

The data storage means has a plurality of classifications, and stores data corresponding to each classification, for example, areas M1, M2, M3, etc. of the total memory 3 that stores sales total data by classification.

The updating means specifies any one of the plurality of classifications and updates the data corresponding to the classification, for example, CPU2 that accumulates registered sales data and steps S4 and S7 processed by this CPU2. Etc.

The flag storage means, when the data corresponding to the designated classification is updated by the updating means, stores a flag indicating that in association with the designated classification. For example, the total sales data etc. at the initial stage or after the transmission is stored. An area M4 and the like of the total memory 3 for storing a flag indicating that it has been updated in association with the sales total data for each classification.

The output designating means is an output of each data stored in the data storing means, for example, a mode switch 1D for designating transmission of total sales data to a data collecting device, and cash / cash /
A custody key or the like.

The determining means determines, based on the flag, which of the above categories the data has been updated when the output of the data is designated by the output designating means, for example, sales prior to transmission processing. CPU2 for determining whether the total data has been updated by referring to the flag, step S35 processed by this CPU2, and the like.

The data output means extracts the category stored by being associated with the flag by the determining means and outputs the data corresponding to the extracted category, for example, the total sales determined to be updated in the total sales data. The transmission unit 4 and the like transmit only data to the data collection device.

The canceling means cancels the flag corresponding to the classification for which the data is output by the data outputting means. For example, for the total sales data transmitted, the flag corresponding to the total sales data transmitted. Is a CPU2 for releasing the total sales data to a state indicating that it has not been updated, and step S28 and the like processed by this CPU2.

[Operation] The operation of the means of the present invention is as follows.

Data storage means for storing data corresponding to each of a plurality of classifications and flag storage means for storing a flag corresponding to each of the above classifications are provided, and any one of the plurality of classifications is provided. By specifying the category, the data corresponding to the category is updated by the updating means. Then, when the data corresponding to the designated classification is updated by the updating means, a flag indicating that is stored in the flag storage means associated with the designated classification. Then, when the output designating unit designates to output each data stored in the data storing unit, the discriminating unit determines, based on the flag, which data in each of the categories has been updated. The data output means extracts the classification stored by the determination means in association with the flag, and outputs the data corresponding to the extracted classification. Further, with respect to the classification whose data is output by the data output means, the flag corresponding to the classification is canceled by the canceling means.

Therefore, it becomes possible to easily transmit only the updated sales total data for each transmission.

It is transmitted to the data collection device described later. Under the control of the CPU 2, sales data and the like are sent to the display unit 5 and the printing unit 6, and the drawer 7 is opened.

The total memory 3 is composed of, for example, a RAM (random access memory), and data writing and reading operations are controlled under the control of the CPU 2. In addition to the area M that stores the total sales data for each transaction and each responsible person, the total memory 3 also includes areas M _{1 to} M ₄ for total sales for each department.
And so on. Here, the area M ₁ is the department code, the area M ₂ is the sales quantity, the area M ₃ is the sales amount, and the area M ₄ is the no sales input flag after transmission, that is, after the sales data by department is transmitted to the data collection device, A flag is stored that indicates whether sales data of the department is to be transmitted depending on whether or not the sales of the department is performed. Further, in the total memory 3, an area M ₅ for storing a post-settlement check-out flag used for detecting the first inspection immediately after the settlement, an area M ₆ for storing a subtotal of one transaction,
Area for storing the machine number unique to the electronic register

Next, the configuration of the electronic register on the master side, that is, the data collecting device will be described with reference to FIG. This data collection device has an individual storage unit K corresponding to the electronic register of each terminal in addition to the totaling storage unit S. Are denoted by the same reference numerals, and the description thereof will be omitted. The tally storage unit S stores tally data for each transaction, each person in charge, and the like, and also stores the number of sales and the amount of sales corresponding to the department code, and the sales data from each slave side is tallyed. . The individual storage unit K is a storage unit corresponding to the number of terminals.
K ₁ has a Kn, each storage unit K ₁ Kn is the corresponding area Mc ₁ for storing the machine number of the terminal that ～Mcn, the area M ₁ for storing sales quantity, sales amount corresponding to the department code ~ M ₃
It is configured to have an area Ms for storing a flag indicating the end of counting.

[Operation of Embodiment] Next, the operation of this embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing the registration operation by department. When the number keys are operated and then the department keys are operated, the flow of FIG. 3 is started. First, the divisional registration process is executed in steps S _{1 to} S ₈ . That is, the department code in the C register is searched from the area M ₁ of the total memory 3 while incrementing the value of the A register (address counter) by +1 (steps S ₁ and S ₂ ).
When the designated department is searched in this way, the number of sales in the area M ₂ corresponding to the designated department is incremented by 1 (step
S ₃ , S ₄ , S ₅ ). Then, the contents of the D register (current sales amount) is added to the sales amount in the area M ₃ corresponding to the specified sector (step _{S 6, S 7, S 8} ). Then area M ₆
The process of adding the sales amount of this time to the subtotal in is executed (steps S ₉ , S ₁₀ and S ₁₁ ).

When such processing is complete, the next step S ₁₂ the area M
_It is determined whether the flag in ₅ is "1". Here, the flag in the area M _5, becomes "1" immediately after the settlement, which becomes "0" at the first inspection after settlement, hence, to step S ₁₂ the first inspection carried out after settlement It detects the initial registration or during, if the initial registration, the flag in the area M ₄ corresponding to the sector specified by the a register is "0" (step S _13). Therefore, if the division-based registration is performed after the first inspection, the flag “0” indicating that the sales data of the division should be transmitted is set, but if it is the initial registration, the area M is set at the time of settlement. _Since all ₄ are cleared, such processing (step S ₁₃ ) is not executed. Thus, the contents of the next step S ₁₄ the A~E register is cleared. In addition, FIG. 6A shows the total memory 3 after the settlement.
Shows the contents of the area M ₁ ~M ₄ of the inner, sales quantity of the area M _2,
All flags in the area M ₄ along with the sales amount of the area M ₃ and has a "0". Then, FIG. 6B shows areas M _{1 to} M ₄ in the total memory 3 when the above-mentioned divisional registration is executed before the first inspection is performed after the settlement.
Shows the contents of. In this case, all the flags in the area M ₄ are “0”, as is clear from the above-mentioned divisional registration operation.

Next, when the mode switch 1D is operated to switch to the inspection mode and the cash / deposit money key is operated, the inspection process is started according to the flow shown in FIG.
That is, first, a transmission signal for informing the data collection device that data is to be transmitted is transmitted, and along with this, it waits until a receivable signal comes from the data collection device (steps S ₂₁ and S ₂₂ ). Then, when a receivable signal arrives, the value of the A register is incremented by 1 in the next step S ₂₃ , and then the area M ₅
Flag of the inner is "1", i.e., the first or servicing after settlement is determined (step S _24). If the first inspection, the value of the A register in the next step S ₂₅ the final address "n"
While either is determined, since initially does not reach the final address, the process proceeds to step S _25. Here machine number from the area M ₇ is the department code from the area M ₁ ~M ₃ specified by the A register is transferred sales quantity, it reads the sales amount to C~F register. Data taken in C~F register this way is sent to the transmission unit 4 is transmitted to the data acquisition device (step S _27). Thereafter, the flag "1" is written into the area M ₄ specified by the A register (step S _28). Then, until the value of the A register is the final address "n", the process returns from step S ₂₉ to step S _21, the result of the above-described operation is repeated, the area of each sector together with the sales data corresponding to each sector is transmitted
Flag in the M ₄ is all set to "1". FIG. 6C shows the contents of the areas M _{1 to} M ₄ in this state. Thus, the transmitting departmental sales data, when the area M ₄ corresponding to the last sector flag "1" is written, the transmission end signal is transmitted along with the machine number (step S _30, S ₃₁₎ . Thus, after the flag in the area M ₅ is set to "0", the contents of A~F register is s cleared respectively (step S _32, S _33).

When the first inspection is completed in this way, the flag in area M ₅ is set to "0". Therefore, when the next inspection operation is performed after performing the departmental registration processing, the flow of FIG. 4 is performed. Although starts running, turn in step S _24, "nO", i.e., it is determined that it is not at the inspection immediately after the settlement, the step
Proceeds to S _34, the flag in the area M ₄ specified by the value of the A register is transferred to B register, the flag on the basis of the contents of the B register is "1" whether the determination is made. In this case, the flag corresponding to the department 1 is first read, but as shown in FIG. 6d, the department is not registered between the first inspection and the next inspection, and the sales data of the department is updated. If not, the flag remains "1", so the process proceeds to the next step _S36 , but initially A
Since the value of the register has not reached the final address "n", the flow returns to step S _21. Therefore, the sales data of the department 1 in which the flag in the area M ₄ remains “1” is transmitted at the first inspection and is not transmitted at this inspection. Then, the department 2 is designated next, and the flag corresponding to the department is read out. However, in the department 2, as shown in FIG. Since the registration has been performed, the flag in the area M ₄ is “0” in step S ₁₃ of the departmental registration processing of FIG. Therefore, in this case, the process proceeds from step S ₃₅ to step S _25, and step S _26, S
Execution of ₂₇ transmits the sales data for department 2. Thereafter, the flag in the area M ₄ corresponding to the sector is set to "1" (step S _28). Such operation is performed for each division, the processing for the last sector ends, the fact is detected in step S _36, so that the step S ₃₀ and subsequent steps are executed sequentially. In this way, in the second and subsequent inspections, registration by department is performed between inspections, and only the updated sales data for that department will be transmitted, so reduce the amount of data transmission. Is possible.

Next, the operation of the data collection device side will be described with reference to FIG. First, the slave side determines whether or not there is a transmission signal, and if there is, transmits a receivable signal (steps S ₄₁ , S
₄₂ ). After that, the presence or absence of the transmission data is determined, and if there is, the memory corresponding to the transmitted machine number is stored in the individual storage unit K.
Is searched, but if there is not, it waits until there is transmission data (steps S ₄₃ and S ₄₄ ). Thus, it is determined whether there is a next step S ₄₅ the end signal, if not, retrieves the division of the transmission data (step S _46). When such a search process is completed, a sales data tabulation process is performed in steps S _{47 to} S ₅₀ . In this case, the totaling is performed for each of the sales quantity and the sales amount, and is performed by subtracting the sales data in the individual storage unit K from the transmission data and then adding the value to the totaling storage unit S. Thus, the flag "1" or in the area Ms corresponding to the next step S all the ₅₁ terminal, i.e., whether aggregation processing for all the terminals has been completed is determined, and if not completed,
Returning to step S ₄₁ , the above operation is repeated. Thus, the flag is "1" in the area Ms in step S _45, the transmission of the terminal detects that it has ended, the flag "1" to the area Ms corresponding to the machine number in the next step S ₅₂ After setting, proceed to step S ₅₁ .

In this way, when the counting process for all terminals is completed,
As it is detected in step S _51, the process proceeds to step S _53, reads the entire contents of the individual storage unit K and aggregate main storage unit S, the feed to the printing unit 5, thereby sequentially printing on a recording paper.
Then, the areas from which data has been read out from the individual storage unit K and the totalization storage unit S are cleared, respectively, and all areas Ms are cleared (steps S ₅₄ and S ₅₅ ).

In the above embodiment, it is determined whether the sales data of the department is to be transmitted according to the flag in the area M ₄ corresponding to each department, but the sales data is determined according to whether the sales data is updated. You may make it discriminate | determining using itself. In this case, the sales data may be the number of units sold or the amount of sales. Further, although all sales data are transmitted at the time of the first inspection, data not registered by the time of the first inspection need not be transmitted.
Besides, various modifications can be applied without departing from the present invention.

[Effects of the Invention] According to the present invention, only the data in which the flag indicating that the data has been updated is stored and the flag corresponding to the classification in which this data is output is canceled. It becomes possible to easily output only the updated data for each output. Therefore, it becomes possible to easily greatly reduce the amount of transmitted data each time data is transmitted by inspection output or the like.
