Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile off-line POS system suitable for use in in-vehicle sales and in-flight sales of vehicles such as trains and airplanes, and more particularly to a POS system having a sales performance totaling function. .

[0002]

2. Description of the Related Art In recent years, a mobile off-line POS system using a handy terminal for reading a bar code has been adopted as a sales system for goods on a train or in an airplane. And, for example, "J
AL VS ANA Conditions for a mega carrier to survive in the 21st century (published by Chuo Shoin Co., Ltd. on April 12, 1993) "
Pages 56-258: "In-flight OA with great merit
As mentioned above, the use of the POS system is particularly expected for duty-free in-flight sales on international flights.

By the way, such a conventional in-flight sales system, as conceptually shown in FIG. 23, comprises a plurality of handy terminals 101, ..., A plurality of small printers 103 ,. It consists of And each handy terminal 10
1 is a function that reads barcodes from the product catalog based on information such as exchange rates of major countries, contract credit cards, etc., identifies the product, converts prices in each currency, calculates change, and credits. It was given a function that enabled it to handle cards.

Each small printer 103 is placed on a wagon pushed by a crew member, and each crew member specifies a product in a catalog at the handy terminal 101 and sets the handy terminal 101 on the small printer 103 each time sales are completed. The small printer 103 is configured to transmit data by optical communication and output a receipt from the small printer 103.
Then, this sales record data has been stored in the handy terminal 101.

For the final totalization, all the handy terminals 101, ... Are set in the communication table 111 connected to the workstation 105, and the sales performance data accumulated in each handy terminal 101 ,. It is implemented by reading the data into the workstation 105 and executing the arithmetic processing in the workstation 105. Then, the totalized result at the workstation 105 is further stored in a RAM card or the like mounted on the workstation 105 and delivered to a host computer on the ground for sales management, credit card billing, and next flight. It was used to create a product supplement list and analyze sales trends.

[0006] The RAM card installed in the workstation 105 stores the function expansion program of the workstation 105, the function expansion program of the handy terminal 101, and the latest exchange rate data necessary for the handy terminal 101. It is stored. Then, the workstation 105 uses these RAs.
The information stored in the M card is searched, and if there is a program for expanding its own function, it is read into its own RAM or hard disk, and the handy terminal 1
When there is a program and data for 01 function expansion, the work is carried out by transferring the program with all the handy terminals 101, ... Set in the communication table 111. A function expansion system using such a RAM card is disclosed in, for example, Japanese Patent Laid-Open No. 62-282
It is widely used in various electronic devices, as introduced in Japanese Patent No. 321, Japanese Patent Application Laid-Open No. 63-39063, Japanese Patent Application Laid-Open No. 2-105284, and the like.

[0007]

By the way, such P
In the OS system, a large workstation 105
Or, a large communication table 111 has to be installed, and it is necessary to secure a space in the vehicle or in the cabin, and in some cases, it may be necessary to modify the vehicle or the cabin to install the system. There was a problem that the installation work was troublesome. In addition, in order to perform the totaling work, it is necessary to always bring the handy terminal 101, ...

In addition, in the function expansion system in the conventional POS system, there are cases where the program is stored in the RAM card and cases where only the data is stored instead, and the program is stored. Also in this case, there are cases where only the function expansion program for the workstation 105 is stored, cases where only the function expansion program for the handy terminal 101 is stored, and cases where both of these programs are stored. In such a case, the workstation 105 generally employs a method of identifying the type of information stored in the RAM card by searching for an identifier indicating the presence or absence of a program (Japanese Patent Laid-Open No. 62-822321). Therefore, there is a problem that the time required to judge the presence or absence of a program depends on which address in the card the identifier is stored. There was a problem that it had to be stored at the top address. In particular, in a mobile offline POS system installed in a train or an airplane, it is necessary to identify not only the presence or absence of a program but also whether it is for a workstation or for a handy terminal. The method used has a problem that it is troublesome and time consuming.

Therefore, a first object of the present invention is to reduce the size of the entire system and to facilitate the installation of the system in a mobile offline POS system suitable for use in vehicles such as trains and airplanes. To do. A second object is to provide a method of giving a function to a system for achieving the first object and to make it possible to easily further expand the function of the system.

[0010]

[Means, Actions and Effects for Solving the Problems]
The mobile off-line POS system of the present invention, which is made to achieve the above object, includes a plurality of bar code reading handy terminals each having a function of accumulating and storing its own sales record data, and the handy terminal. A mobile off-line POS system comprising one or more portable printers, each of which has a communication means for communicating with a handy terminal via the communication means and a receipt issuing means for selling a product. Then, the sales record data stored in each handy terminal is read into at least one of the printing devices by using the communication means, and the sales records of at least two or more handy terminals are aggregated. In addition to providing an arithmetic function capable of performing processing, the printing device further has a read sales record. A function to identify which handy terminal the data was stored in and to notify the outside of the information to determine the completion / non-completion of the reading, and the sales made based on the calculation function. It is characterized in that it is provided with a writing function of writing the totalized data of the actual results into a portable storage medium.

The printing devices may be provided in the same number as the handy terminals, or one printing device may be provided for two or more handy terminals. Further, the above-mentioned calculation function, notification function, and writing function may be provided in all of the printing devices that make up the system, or only one of them may be configured to have the above-mentioned functions. Is.

According to this mobile off-line POS system, the handy terminals are sequentially set in the communication means of the printing device having the above-mentioned arithmetic function,
The sales record data in each handy terminal is read into the printing device, and the total or part of the system is totaled and the totalized data is written in the storage medium. At this time, since the printing device is provided with an informing function for informing the outside of the information for determining whether the reading of the sales record data from each handy terminal is completed or not completed, the operator of the system is You can easily know from which handy terminal the sales performance data has already been read. Therefore, despite replacing the handy terminal of the same shape in a narrow place such as an airplane or train, while performing the aggregation work,
It is possible to accurately prevent the occurrence of defects such as forgetting to read.

Therefore, it is not necessary to provide a large work station and a large communication terminal capable of setting all the handy terminals at a time as in the conventional case, and the space in a train or an airplane is not compressed. Moreover, despite the discontinuation of such communication terminals, it is possible to accurately prevent the occurrence of forgetting to read the sales record data from the handy terminals having the same shape, and it is possible to smoothly and correctly perform the totaling work.

Here, in this mobile off-line POS system, each of the handy terminals is provided with display means for displaying sales price, change, etc. for each sale of goods, and completion / non-completion of the reading from the printing device. When the information for discriminating the information is notified, the display means is provided with a reading status display function for performing a display for discriminating whether the reading of each handy terminal is completed or not based on the information.

With this configuration, the operator can easily and surely know which handy terminal should be set next by performing a display based on the reading status display function while performing the above-mentioned totalizing work. be able to. Moreover, it is possible to easily confirm whether or not the reading is completed for all the handy terminals.

In this case, further, in this mobile offline POS system, each of the handy terminals requests the printing device to notify the information for determining whether the reading is completed or not completed. A reading status request function is added.

With this configuration, after the sales performance data of a certain handy terminal is read by the printer, which handy terminal is to be set next must be read. It is easy to find out and makes the counting process smooth.

Further, in these mobile offline POS systems, each of the handy terminals reads all the handy terminals when it receives the information for determining the completion / non-completion of the reading from the printing device. If it is determined that the reading is completed for all the handy terminals, the printing device is instructed to complete the counting and the counting data is written in the storage medium. A function to instruct the completion of counting is added.

With this configuration, it is possible to automatically instruct the completion of the totaling work, so that the operator
All you have to do is to set up the handy terminals one by one according to the contents displayed by the reading status display function, and you can easily finish all counting work.

Separately from this, in the mobile offline POS system, the printing apparatus is forced to instruct to complete counting based on the data read so far and to write the counting data into the storage medium. A forced completion instructing means may also be provided.

[0021] This does not always add up the sales results of all the handy terminals, but it is possible to add up the sales results of only a specific handy terminal, and it is possible to expand the system usage variation. Because. For example, in the case of in-flight sales, not all handy terminals have sales results, but if only some handy terminals have sales results, set all handy terminals. There is no need to carry out the processing, and if only some of these handy terminals are set to carry out the processing and the forced completion instructing means is activated, there is no waste and it becomes even more convenient.

In these mobile offline POS systems, each handy terminal has an initialization function for automatically returning the sales record data to the initial state after the sales record data is read by the printer. Have. This is because the aggregation work is performed while replacing the handy terminals of the same shape, which is convenient for avoiding the situation where data is read redundantly from the same handy terminal. In addition, for the POS system in the aircraft, it is desired to separate ": totaling the sales results from the departure point to the relay point" and ": totaling the sales results from the relay point to the destination". Therefore, in such a case, there is a meaning that the sales record from the first departure point to the relay point is not accidentally added to the sales record from the next relay point to the destination.

Further, in addition to the first object, the mobile off-line P of the present invention, which has been made to achieve the second object.
The OS system is a mobile offline P
In the OS system, the printing device and the handy terminal each have a CPU, a ROM, and a RAM inside.
And a program loading function for loading the printing device program stored in a removable storage medium for control into its own RAM to obtain each of the functions. An information transfer function for transmitting the handy terminal program and data stored in the control storage medium to the RAM of each handy terminal through the communication means to execute the function addition to the handy terminal, and for the control. By storing the printing device program, the handy terminal program, and the handy terminal data in the storage medium in a file format by providing separate dedicated directories, respectively, the storage medium can detect whether or not there is information in each directory. Whether there is a program to read and transfer to the handy terminal Characterized by being configured to determine the presence or absence of should do the program and data to the CPU of the printing apparatus.

According to this system, when the control storage medium is attached to the printing device, the printing device only needs to check the presence or absence of the information in each directory to quickly determine what work should be performed next. can do. Therefore, in order to achieve the first object of the present invention, it has become impossible to expand the functions of the respective handy terminals at one time, but it is possible to quickly identify the work to be executed by the printing device, so that it is possible to expand the functions. The time required for etc. is saved as a whole. Further, even when information is stored in this control storage medium, it is sufficient to store the information in separate directories, so there is no need to adjust the storage order according to the type of information.

On the other hand, as shown in FIGS. 2 and 3, the BHT has a liquid crystal display screen 41, a key switch 43 and a function switch 45 on the upper surface, and a photo coupler 47 on the back surface. The key switch 43 includes a numeric keypad, a cursor key, a backspace key, a cancel key, a shift key, a power switch, and the like, and is used for inputting the amount of money received at the time of in-flight sales. There are eight function switches 45, F1 to F8, which are mainly keys for switching currency. For example, the currency of major countries such as yen, dollar, franc, pound, mark, yuan, etc. can be selected.

The BHT has a bar code reader 49 at the front end, and a battery 51 on the rear end lower surface.
Is attached. The button 53 on the side surface is for instructing to read the barcode. The barcode reader unit 49 is an LED substrate that emits red light, LE
Consists of a condenser lens for condensing and diffusing light from the D substrate and guiding it onto the bar code label, a dustproof plate covering the opening, a rubber buffer cover, a flat reflecting mirror, an imaging lens, an image sensor, etc. It is known.

Inside the BHT, as shown in FIG. 5, a computer 60 mainly including a CPU, a ROM, a RAM and an I / O is incorporated. A liquid crystal display screen 41, a key switch 43, a function switch 45, a photo coupler 47, a bar code reader 49, and a read button 53 are connected to the I / O.

The BHT receives a program for expanding the BHT function by optical communication with the BED,
By being installed in the program storage area in the RAM, the arithmetic processing function described later is added. Further, data such as an exchange rate necessary for arithmetic processing is also received from the BED by optical communication and installed in the data storage area in the RAM.
A program for realizing a communication function via the photocoupler 47, a program for reading a barcode via the barcode reader unit 49, etc.
A basic program for operating the is stored in the ROM. Further, the RAM is backed up by the battery 51 even after the power is turned off.

Next, the information stored in the memory card 25 will be described. As shown in FIG. 6, directories A, B, and C are provided inside the memory card 25. The directory A has a BED function expansion program, and the directory B has a BHT function expansion program. However, the directory C stores data necessary for in-flight sales such as exchange rates in a file format.

Next, a method of using the POS system of this embodiment and a process executed by each CPU of BHT and BED will be described. First, a process related to BED function expansion will be described. This process is executed immediately before receiving the new memory card 25 before the flight. First, the memory card 25 is inserted into the slot, and the BED is powered on normally. Then, the CPU of the BED starts the processing shown in FIG.

First, it is determined whether or not the memory card 25 is inserted in the card slot 23 (S10).
When the card is inserted, depending on the presence / absence of files in the directory A in the memory card 25,
It is determined whether or not there is a BED function expansion program (S12). When the BED function expansion program exists, the program file in the directory A of the memory card 25 is transferred to the program storage area secured in the BED RAM (S14).

Then, the program transferred to this program storage area is activated (S16). Thus, B
The function of the ED is expanded. Note that the transfer in S14 is R
It is configured such that the old program file in the AM is overwritten with the new program file.

On the other hand, if no file exists in the directory A of the memory card 25 (S12 = N
O), the process proceeds to S16 as it is, and the old program stored in the RAM from before is activated. In this case, B
The ED function will not be expanded.

Next, the processing relating to the function expansion of BHT will be described. In this process, when the BED is powered on, a power-on method dedicated to the BHT function expansion process is executed. Specifically, the power switch and another specific switch are simultaneously pressed. Also, for the BHT, the power-on method dedicated to the BHT function expansion processing is executed. Again, press the power switch and another specific switch at the same time. Then, the BHT is set in the recess 11 of the BED. By these procedures, the CPU of BHT and the CPU of BED start the processing shown in FIG.

First, the BHT CPU requests the BED to start the BHT function expansion processing (S2).
0). Then, the CPU of BED is the memory card 25
After confirming that the BHT function has been inserted into the card slot 23 (S22), the presence or absence of the file in the directory B in the memory card 25 determines whether or not there is a BHT function expansion program (S24). When the BHT function expansion program exists, the program file in the directory B is output as an optical signal through the photocoupler 19 while using the work area in the BED RAM as a communication buffer (S26). Then BH
The CPU of T receives this optical signal by the photocoupler 47 (S28), and stores it in the program storage area secured in the RAM of BHT (S30). Also at this time, the new program file is stored by overwriting the old program having the same file name.

In this way, the BHT function is expanded.
If there is no memory card 25 or if there is no program file in the directory B, the CPU of the BED outputs an optical signal indicating that there is no file from the photocoupler 19 (S34), and the CPU of the BHT side When the file-less signal is received (S36), B
The HT will not be expanded.

Next, registration of various data such as "exchange rate", "contract credit card information" and "product information" necessary for carrying out in-flight sales from a memory card, flight number, date, leg ( Enter flight information such as departure and destination information). This process is called pre-processing.

In the pre-processing, the memory card 25 is attached to the BED and the BED power is normally turned on.
Then, regarding "contract credit card information", B
The data is stored in the BED data storage area by the same processing as in the case of expanding the function of the ED. When the BHT is turned on, the power switch and the numeric keypad “1” are pressed simultaneously. Then, the BHT is set in the recess 11 of the BED. By these procedures, the BHT CPU and the BED CPU start the processing shown in FIGS. 9 and 10.

First, the CPU of the BHT requests the BED to transfer various data other than the "contract credit card information" (S40). Then, the CPU of BED
Confirms that the memory card 25 is inserted into the card slot 23 (S42), reads the data file stored in the directory C in the memory card 25, and communicates with the work area in the BED RAM. While being used as a buffer, it is output as an optical signal via the photocoupler 19 (S44). Then, the CPU of the BHT receives this optical signal at the photocoupler 47 (S46) and stores it in the data storage area secured in the RAM of the BHT (S48). At this time,
Store a new data file by overwriting old data with the same file name. If the memory card 25 is not inserted, the BED sends the message of no card (S50), the BHT receives it (S52), displays an error message on the liquid crystal display screen 41 (S54),
It returns to S40 again. This error loop can be removed by the crew member inserting the memory card 25 into the card slot 23 of the BED.

Next, the CPU of the BHT determines whether the flight information has been input (S60). The determination as to whether or not the flight information has been input is made by checking whether or not all the flight information is stored in the data storage area in the RAM of the BHT.

When no flight information is input (S60 = NO), the BHT CPU requests the BED to transfer fixed flight information data (S6).
2). Then, the CPU of BED is the memory card 25
The fixed data of the flight information is read from and output as an optical signal via the photocoupler 19 (S64). Then, the CPU of the BHT sends this optical signal to the photo coupler 47.
Is received (S66) and is stored in the data storage area secured in the RAM of the BHT (S68).
The fixed data of the flight information stored here includes the employee number of the chief parser, the group number of the chief parser, and the like.

After the fixed data of flight information is stored in this way, a screen prompting the user to enter a sales date is displayed next.
Waiting for the sale date to be input, a sale date input process (S70) of storing the sale date in the RAM is executed. Then, flight number. Display a screen prompting you to enter the flight number, wait for this input, and enter the flight number. No. stored in RAM. Input processing (S72) is implemented. Subsequently, a screen to the effect that the leg of the current flight should be input is displayed, and the leg input processing (S74) of waiting the input and storing the leg in the RAM is executed. It should be noted that the leg is information that specifies the departure point and the destination point of the flight, as described above. For example, from Narita to New York, "NRT-
Information is entered by an abbreviation such as "JFK".

Thus, when the input of the leg is completed, the menu screen is finally displayed and the preprocessing is finished (S7).
6). Then, the process shifts to the work selection process. On the other hand, when the flight information has already been input (S60 = YES), an inquiry screen as to whether or not the flight information currently input is deleted and re-registered is displayed (S78). Then, if there is a key input indicating that deletion may be performed, the process proceeds to S62, flight information registration processing is executed, and if there is a key input indicating that deletion should not be performed. In step S80, the main menu is displayed (S80).

Next, the main menu will be described.
As the main menu, as shown in FIG. 11, "1:
A screen prompting the user to select either "SALES" or "2: SAUMMARY" is displayed. "SALES" is a process related to implementation of in-flight sales using a product catalog,
“SUMMARY” is a process for totaling the total results of in-flight sales.

When the power of the BHT is normally turned on, if the above-mentioned preprocessing is completed, this menu screen is immediately displayed. Next, the task selection process after displaying the main menu will be described. After displaying the main menu, the BHT executes the task selection process shown in FIG. That is, waiting for the input of "1" or "2" with the ten keys (S90), if "1" is selected, the process proceeds to the sales process (S100), and if "2" is selected, the aggregation process (S200). ).

First, the selling process will be described. The sales process is the sales product registration process described in FIGS.
The payment processing described with reference to FIGS. 15 to 17 and the cancellation processing described with reference to FIG.

When "1" is selected in S90, first,
The sale item registration process in the sale process (S100) is started, and a bar code reading screen is displayed (S102).
Then, when the bar code in the product catalog is read or the cancel key "C" in the key switch is pressed, the process proceeds to the next process (S104). If the cancel key "C" is pressed, the main menu is displayed (S106) and the process returns to the job selection process.

When the bar code is read, it is determined whether or not it is a cancel bar code (S10).
8). If it is a cancel bar code, proceed to the later-described cancel processing, and if not, display the product name, quantity, and unit price corresponding to the bar code in one line, and at the same time, at the bottom of the screen at that time. Sales status display processing for displaying the subtotal of is executed (S110). Specifically, as shown in FIG. 14 (A), abbreviated names are used for product names (“O / WATCH” is an abbreviation for the original watch), and the unit price, number, and subtotal of the basic currency are displayed. To be done. When one passenger desires to purchase a plurality of same products, the number is set by reading the bar code a plurality of times.

Next, the user waits until the enter key "ENT" is pressed, the bar code is read, or the cancel key "C" is pressed (S11).
2). When the barcode is read here, S10 is again executed.
The processing after 8 is repeated. When added by this repetition, the product name, the number, and the unit price read this time are displayed as illustrated in FIG. Then, the subtotal of all the sold products up to this point is displayed. In addition, "O / T SHI
"R" is an abbreviation for original T-shirt.

On the other hand, in S112, the cancel key "C"
When is pressed, the information of the last selected product among the products currently displayed is cleared and then the process proceeds to S114 (S116). Then, when the cancel key "C" is pressed again in S114, the information of all the selected products is cleared and the display returns to the bar code reading screen (S118).

In this way, the selection and cancellation of the products are executed, and when the selection of the products desired by the passenger is completed, S11
2. In S114, the enter key is pressed. Then, the next payment process starts. In the payment process, the total price of the selected products is displayed (S120), and the key input is awaited (S122). In this state, when the number "0-9" is input from the ten keys, the deposit amount is set corresponding to the input number (S124). On the other hand, when the backspace key "BS" is pressed, the total amount displayed in S120 is set as the deposit amount (S126). That is, the sales crew member can omit the input of the deposit amount by pressing the backspace key "BS" when the amount of deposit from the passenger is just right.

When the deposit amount is set in this manner, the total amount and the deposit amount are compared to determine whether or not the deposit is insufficient (S128). When it is determined that the deposit is insufficient, the display is changed by replacing the insufficient amount with the total amount (S130). On the other hand, when it is determined that there is no shortage of deposit, it is determined whether there is change as shown in FIG. 16 (S132). If it is determined that there is change, the amount of change is displayed (S134). Then, key operation "F2-F8" or enter key "EN" for instructing currency change
Wait for the operation of "T" (S136).

Here, the currency is F of the function key.
By pressing F2 to F8 once or by pressing F2 to F8 of the function keys twice in succession, it is possible to change to any of the currencies of the 14 major countries. When the enter key is operated, the BED is instructed to print the receipt (S138), and the sales record data is set to the receipt number. At the same time, the data is stored in the data storage area in the RAM (S140), and the process returns to the beginning of the sale item registration process. On the other hand, when the currency change key is operated, the change is converted in the currency selected by the operation (S142), and the process returns to the change display.

On the other hand, in the processing of S122 of FIG.
Press F2-F8 of function key once or F2-
If F8 is pressed twice in a row, change the currency,
The total amount of money is converted into a new currency (S144), and the total amount of money is displayed again. Further, in the processing of S122, when F1 of the function key is pressed alone, the processing shifts to the card sales processing (S150) for selling with a credit card instead of cash.

In the card selling process, as shown in FIG. 17, first, the total amount is displayed again (S152),
Wait for key input (S154). In this state, when the number "0-9" is input from the ten-key pad, the card usage amount is set corresponding to the input number (S156). On the other hand, when the backspace key is pressed, the total amount displayed in S152 is set as the card usage amount (S158). Here again, when paying the entire amount with a card, it is possible to omit the input of the card usage amount. Note that this S154
When the cancel key is input in step S10, the processing for card sale is exited and the process returns to step S120.

After the card usage amount is set in S156 and S158, the input of the ID number of the sales crew member is waited (S160), and then the credit card is read (S162). Then, the process proceeds to the determination as to whether or not there is a shortage of deposit (S128 in FIG. 15), and thereafter the change processing (S132 to S136), the receipt printing (S138), and the sales record data storage (S140).
And the sequential processing is executed. The reason why the ID number of the flight attendant in charge of sales is input in S160 is to clarify the person in charge when a trouble occurs at a later date with respect to sales by credit card. Next, the cancel process will be described. This canceling process is executed when the cancel barcode is read in the sale item registration process. This is a process executed when accepting a return of a product once sold.

In the cancel processing, as shown in FIG. Waits for input (S180).
Then, the receipt number. Is input, the receipt number. The total sales amount of the transaction specified by is displayed as a refund amount (S182). Then, it waits for a key input (S184).

In this state, if there is a key input "F2 to F8" meaning a currency change, the refund amount is converted into the changed currency (S186), and the process returns to the refund amount display process. If the cancel key "C" is pressed in S184, the process returns to the beginning of the sale item registration process.

Then, in S184, the enter key "EN
If "T" is input, the BED is instructed to print a cancel receipt (S188), and the corresponding receipt number is selected from the sales record data in the RAM. The data of is deleted (S190). Then, the process returns to the beginning of the sale item registration process.

In this way, in the main menu, "1:
When "SALES" is selected, a sale item registration process, a payment process, and a cancellation process are executed. Then, in the sale merchandise item registration process, by pressing the cancel key in S122, the process returns to the main menu again.

Next, in the main menu, "2: SU
Aggregation processing when "MMARY" is selected (S200)
Will be described. In addition, when executing the aggregation process,
The sales crew member collects 6 BHTs at any one of the 6 BEDs. And each BHT
Turn on the power and select "2" from the main menu. Then, the BHT is set in one BED.

Then, as shown in FIG. 19, first, a total confirmation screen is displayed (S202). Then, a command for inquiring whether or not the power is turned on is transmitted to the BED, and a response thereto is waited for (S204, S2).
06). When there is a response from the BED indicating that the power is on, a command for inquiring whether the memory card 25 is attached is transmitted to the BED, and a response thereto is waited (S208, S210). Here, "O
If there is a response of "K", then, a command for inquiring whether or not the number of times of counting is within a prescribed number is transmitted to the BED, and a response thereto is waited (S212, S214).

Then, when there is a response of "OK" to this, finally, the sales record data stored in its own RAM is transmitted to the BED together with its own BHT number, and the reception completion response is waited ( S216, S218). If there is a reception completion response, first, the sales record data in the RAM is erased (S220), and then, as shown in FIG. 20, a command requesting the tabulated BHT number is transmitted and a response to this is sent. Wait (S222, S224).
Then, if there is a response to this, the BHT already collected
The number is displayed on the screen (S226).

Subsequently, it is determined whether or not the BHT numbers received in S226 are all six (S228).
If it is determined that all the six cars are included, a command is issued to the BED to instruct execution of the counting (S23
4) Wait for the response of completion of counting to be returned (S23)
6). Then, when the response of the completion of counting is returned, the power is turned off (S232). Further, when it is determined that not all of the six vehicles are included, it is determined whether to forcibly perform the aggregation (S230). At this time, by pressing the numeric keypad “1” from the BHT, “YES” is established,
By pressing "2", "NO" is established. When "2" is pressed and "NO" is established,
The power of the BHT is immediately turned off (S232). On the other hand, if "1" is pressed and "YES" is established, B
A command for instructing execution of totaling is transmitted to the ED (S234), and waits for a response of completion of totaling to be returned (S236). Then, when the response of completion of counting is returned, the power is turned off (S232).

If "NO" is determined in S206 and S210, an error message is displayed (S238), the process returns to S204 and S208 again, and waits for the "OK" response. In addition, if it is determined to be "NO" in S214, it is impossible to store the sales result data when the memory card 25 is full and the totaling is performed.
Interrupt the process and replace with a new memory card.

During this period, the BED executes the totaling process (BED side) as shown in FIG. Waiting for the command from the BHT to inquire whether the power is on or not, and responding "OK" (S250, S).
252). Then, it waits to receive a command from the BHT to inquire whether the memory card 25 is attached (S254). Here, it is confirmed whether or not the memory card 25 is mounted. If the memory card 25 is mounted, "OK" is returned, otherwise "NO" is returned (S256 to S26).
0). When the response is “NO”, the process returns to S250 and waits again for a command from the BHT. The operator
In the meantime, the memory card 25 is mounted while observing the error display on the BHT. Then, the process proceeds to S258 and "OK"
Is returned, and the process can be shifted to the next process.

In the next process, the process waits for the reception of a command asking whether the total number of times is less than the specified number (S262). Then, it is confirmed whether or not it is within the specified number of times, and the result is transmitted (S264 to S268). In addition, when transmitting that the total number of times exceeds the specified number of times, the process is interrupted, and only when the information indicating that the total number of times is less than the specified number of times is transmitted, the next process can be performed.

In the next process, the process waits until the sales record data and the BHT number are received from the BHT (S270). Then, when received, the received sales record data is added to the total data of the work area in the RAM (S27).
2). Then, the reception completion response is output (S27).
4).

Next, the reception of a command requesting the totalized BHT number is awaited, and a response to this is output (S
276, S278). Then, it waits for a command to be received (S280). When the command is received, it is determined whether it is a command for instructing execution of counting or a command for inquiring about power-on (S282). If it is the latter, the process returns to S252 and the response of “OK” is given. If it is the former, the result of totalizing the work area total data is printed as a total list (S284), and the total data is stored in the memory card 25 (S28).
6). Then, when these are finished, turn off the power (S
288).

As described above, according to this embodiment, 6
With just one BHT and six BEDs, you can do everything from in-flight sales to total in-flight sales results. Therefore, the problem of pressure on the space inside the machine unlike the conventional system involving a workstation does not occur. In addition, P to the cabin
There is no need to modify the OS system for installation,
Moreover, it is not necessary to carry in large-scale equipment.

In addition, despite the fact that such a compact system is realized, each BHT has BE sales data.
When the data is transmitted to D and the total is executed, the sales data in the RAM is erased, so that the same type of BHT is not set twice and the data is not duplicated. Also, B
Since the configuration is such that the HT number is sent to the BED together with the sales data, the totaled BHT number is requested to be returned from the BED, and this is displayed, it is mistaken which BHT should be set next to perform work. Absent. Then, since it is configured to automatically determine the completion of the aggregation processing by determining that the aggregation of all 6 BHTs has been completed, the operator
It is sufficient to simply set the BHTs one after another and repeat the processing, and no troublesome judgment is required.

Further, in the embodiment, it is configured such that the completion of counting may be forcibly instructed even if not all 6 units are used. For example, only 4 of 6 BHTs are used for in-flight sales. In such a case, it is convenient that only the used BHTs are set in order and processed, and when they are completed, the totaling can be performed.

In addition, in this embodiment, the memory card 2
It was configured to use BED and BHT to expand the functions of BED and BHT.
Since the HT function expansion program and the data are configured to be stored in separate directories in file formats, the presence or absence of the function expansion program can be easily and quickly determined. Therefore, although the functions of the BHT cannot be expanded at a time for six units, the processing time for expanding the functions is not unnecessarily lengthened. Further, it is convenient to repeatedly use the memory card 25 without the trouble of always storing the identifier for identifying the presence or absence of the function expansion program at the head address.

Although one embodiment has been described above, the present invention is not limited to this embodiment, and various embodiments can be adopted without departing from the scope of the invention.
