Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register having a mode switch for selectively switching various business modes such as registration and settlement.

[0002]

2. Description of the Related Art An electronic cash register that functions alone or as a POS (point-of-sale information management) terminal normally registers sales data of a product in a storage unit when data relating to the product is input from a keyboard or the like. Registered business mode that processes and acquires total sales data,
When data related to a canceled product is input from the keyboard, etc., the sales data of the product is canceled and registered from the storage unit to correct the total sales data. The return registration operation mode, a report of the sales total data stored in the storage unit is displayed. Execution of inspection business mode that outputs by printing method, settlement business mode that outputs the report of the sales total data stored in the storage unit and then clears the contents of the storage unit, business mode such as registration and return registration In doing so, it is possible to selectively execute various business modes such as a preset business mode in which data such as a unit price of a product necessary in advance is set in the storage unit.

As a means for selecting one of these business modes, a mode switch SW which is rotated by a key as shown in FIG. 8 is generally used. The rotation range of the mode switch SW is limited depending on the type of key. In the case of the mode switch SW shown in FIG. 8, the first key having a rotation range A1 from the key position of the set business mode to the key position of the settlement business mode and the key position in the rest state to the inspection business mode are rotated. There is a second key having a range and a third key having a rotation range from a key position in a rest state to a return registration business mode.

In a store that uses an electronic cash register equipped with such a mode switch SW, the first key is used by the manager such as the store manager, and the second key is used by the manager of the cashier. By restricting the third key to be used by ordinary cashiers, it is possible to improve management safety.

By the way, in the conventional electronic cash register having this kind of mode switch, the key position of the mode switch and the business mode selected by the key position are fixed by the control program, and the electronic cash register. When the control unit of the register recognizes the change of the key position of the mode switch, the control unit of the register is configured to select and execute the application program of the business mode set by the control program for the changed key position.

[0006]

However, in the conventional electronic cash register having the mode switch, the correspondence between the key position of the mode switch and the business mode selected by the key position is fixed by the control program. However, the control program itself had to be modified in order to change this correspondence. However, since it takes a lot of time and cost to modify the program, it is practically difficult to change the key position of the mode switch to a desired mode due to the convenience of the store.

For this reason, for example, in a store that uses an electronic cash register having a mode switch SW shown in FIG. 8, a general cashier may perform the inspection work mode, but the execution of the return registration work mode is prohibited. Even if such an operation was attempted, it was not possible to realize the above-mentioned execution restriction of business by properly using the key.

The present invention has been made under such circumstances, and an object of the present invention is to provide a key position of a mode switch operated by a key and a business mode selected at the key position. It is an object of the present invention to provide an electronic cash register in which the correspondence relationship of can be arbitrarily changed without changing the control program, and the execution restriction of the work desired by the user can be easily realized by properly using the key. .

[0009]

The present invention has a mode switch which is operated by a key for selecting various business modes such as registration and settlement, and a program of the business mode selected by this mode switch. In the electronic cash register for executing the sales registration process of the product sales data by executing the program storage means for storing each application program of various business modes and the hard code corresponding to each key position of the mode switch. A file reading means for externally reading a code-corresponding file in which business codes that specify various business modes such as registration and settlement are set,
File storing means for storing the code corresponding file read by this means, and hard code reading means for reading the hard code corresponding to the current key position of the mode switch,
A memory search means for searching the code corresponding file stored in the file storage means by the hard code read by this means to read the corresponding business code, and a business mode corresponding to the business code read by this search means. Program selection executing means for reading the application program from the program storage means and executing it.

[0010]

According to the present invention having such a configuration, the code corresponding file read from the outside by the file reading means is stored by the file storage means. In this state, when the hard code corresponding to the current key position of the mode switch is read by the hard code reading means, the code corresponding file stored in the file storage means is searched and the business code corresponding to this hard code is searched. Is read. Then, the application program in the business mode corresponding to this business code is read from the program storage means and executed.

Therefore, a desired business mode can be assigned to each key position of the mode switch simply by modifying the contents of the code corresponding file. Since the modification of the code-corresponding file is merely a modification of the data, it can be carried out easily and in a short time as compared with the modification of the control program.

There are three types of keys: a second key and a third key that can be rotated in the rotation range A2 from the rest position to the key position M2.

FIG. 4 is a block diagram showing a main configuration of the cash register main body 1. In the cash register main body 1, a CPU (central processing unit) 11 as a control unit and a ROM (main memory unit) as a control unit. Read only
Memory) 12 and RAM (random access memory) 13, clock circuit 14 for clocking date and time, communication interface 15 for controlling data communication performed with a host device which is a line-connected host device, and the mode switch 6 is input and a drive signal to the drawer opening device 5a for opening the drawer 5 is output I
The / O port 16 and the like are mounted.

Further, a keyboard controller 17 for receiving a key signal from the keyboard 2, a display controller 18 for sending display data and the like to the display 3, a printer controller 19 for sending print data and the like to the printer 4, Various input / output device controllers such as an HDD controller 21 for writing and reading data to and from the hard disk device 20 are also mounted.

Then, the CPU 11, the ROM 12,
RAM 13, clock circuit 14, communication interface 15,
I / O port 16 and various input / output device controllers 1
7, 18, 19, and 21 are electrically connected by a bus line 22 such as an address bus and a data bus.

In the hard disk device 20, as shown in FIG. 5, each business code 31 for specifying various business modes such as "registration", "return registration", "inspection", "settlement", and "setting", respectively. A program file 30 is registered as a program storage unit that stores an application program 32 for executing the business mode of. Further, the “registration”, “return registration”, “inspection”, and the like for each hard code 41 corresponding to each key position M1 of the mode switch 6
A code corresponding file 40 in which business codes 42 such as “payment” and “setting” are stored is registered.

Incidentally, in this embodiment, the hard code of the key position M1 is "1010", the hard code of the key position M2 is "1020", the hard code of the key position M3 is "1030", and the hard code of the key position M4 is The hard code is "10
40 "and the hard code of the key position M0 is" 1000 "
And

The contents of the program file 30 and the code-corresponding file 40 can be modified at any time by downloading from the host device connected to the line via the communication interface 15.

The ROM 12 stores fixed data such as a control program for controlling the CPU 1. The RAM 13 is formed with various memories for storing variable data such as a storage unit for performing sales registration processing of product sales data.

Then, in the RAM 13, as shown in FIG. 6, a selected program expansion memory 51 in which the application program selectively read out from the program file 30 is expanded and the code corresponding file 40 are expanded. Code-corresponding file expansion memory 52, record read pointer P of the code-corresponding file expansion memory 52
Is formed, and a flag memory 54 of a continuous startup flag F which is set when continuous startup without changing the work is designated by a predetermined key operation of the keyboard 2 is formed.

When the CPU 1 is started up by turning on a power switch (not shown), the R
It is configured to execute the processing shown in the flowchart of FIG. 7 based on the control program in the OM 12.

That is, first, as ST (step) 1, the flag memory 54 is examined to determine whether or not the continuous startup flag F is set. When the continuous startup flag F is reset, the initial startup is designated, so the code corresponding file 40 is read from the hard disk device 20 in ST2 (file reading means).

Next, as ST3, the hard disk device 2
The code corresponding file 40 read from 0 is expanded in the code corresponding file expansion memory 52 (file storage means).

Next, in ST4, the signal of the mode switch 6 input through the I / O port 16 is waited for the current key position to be switched from the rest position to another position. When it is detected that the key position other than the rest position is switched by the change of the signal from the mode switch 6,
At ST5, the hard code at the current key position is obtained from the signal of the mode switch 6 (hard code reading means).

Next, as ST6, the pointer memory 5
The record read pointer P of No. 3 is initialized to the value of the first record of the code corresponding file expansion memory 52. Thereafter, in ST7, the record of the hard code and the business code indicated by the record read pointer P is read from the code corresponding file expansion memory 52 (memory search means).

Here, if the business code of the record is "0" in ST8, the mode switch 6 has been switched to the key position where the business mode is not set, so an error is displayed on the display 3 in ST9. And return to ST4. Then, if it is detected that the mode switch 6 is switched to another position, the processes after ST5 are executed.

On the other hand, if the business code of the record read in ST8 is not "0", the hard code of the record is compared with the hard code acquired in ST5 in ST10. If they do not match, ST1
After incrementing the record read pointer P as 1, the process returns to ST7 and the same processing is repeated.

If the hard codes match in ST10, the business code of the record is acquired in ST12, the application program of the relevant business code is read from the program file 30 of the hard disk device 20, and the selected program expansion memory 51 is read. Expand to. Thereafter, in ST13, the application program expanded in the expansion memory 51 is executed to process the corresponding business mode (program selection executing means).

When the continuous start-up flag F is set in ST1, the process proceeds to ST13 without executing the processes of ST2 to ST12 and executes the application program loaded in the loading memory 51. , Process the applicable business mode.

The key signal from the mode switch 6 is constantly monitored during execution of this application program, and ST
When it is detected that the key position is switched to the key position other than the rest position as 14, it returns to ST5 and repeats the same processing as the above.

Incidentally, the continuous startup flag F is set by designating continuous startup by a predetermined key operation when the power is off. Alternatively, it may be set by operating a predetermined key when the power is turned on.

In the electronic cash register of this embodiment constructed as described above, a desired business code can be assigned to each key position of the mode switch 6 which is switched by a key.

For example, as shown in FIG. 3 (a), the key position M1 is assigned the registration operation mode, the key position M2 is assigned the return registration operation mode, and the key position M3 is assigned the inspection operation mode. Assuming that the settlement business mode is assigned to the key position M4 and the setting business mode is assigned to the key position M0, first, as shown in FIG. 5, the hard code “1010” of the key position M1 is assigned to the hard disk device 20. The business code "registration" is set for the key code M2, the business code "return registration" is set for the hard code "1020" at the key position M2, and the business code "check" is set for the hard code "1030" at the key position M3. , The business code “settlement” is set for the hard code “1040” at the key position M4, and the business code “setting” is set for the hard code “1000” at the key position M0. To load the code corresponding file 40 that.

In this way, when the electronic cash register is initialized by turning on the power switch or the like, the code corresponding file 40 is read from the hard disk device 20 and expanded in the code corresponding file expanding memory 52. It Then, for example, the mode switch 6
When the key is switched to the key position M1 with the key, the code corresponding file expansion memory 52 is searched using the hard code "1010" of the key position M1 as a search key, and the corresponding business code "registration" is read. Then, the registration business program is selected and executed from the program file 30 of the hard disk device 20, and the registration business is processed.

Further, for example, when the mode switch 6 is switched to the key position M2 with a key, the code corresponding file expansion memory 52 is searched using the hard code "1020" of the key position M2 as a search key, and the corresponding business code. "Return registration" is read. Then, the return registration work program is selected and executed from the program file 30 of the hard disk device 20, and the return registration work is processed.

On the other hand, in the above electronic cash register, as shown in FIG. 3 (b), when the check operation mode is assigned to the key position M2 and the return registration operation mode is assigned to the key position M3, The hard code "1" of the key position M2 of the data of the code correspondence file 40 shown in FIG.
The business code corresponding to "020" is changed to "check", and the business code corresponding to the hard code "1030" at the key position M3 is changed to "return registration" to load the code correspondence file 40.

In this way, when the electronic cash register is initially started up, the hard disk drive 20
The code-corresponding file 40 after the change is read from and is expanded in the code-corresponding file expansion memory 52. In this case, when the mode switch 6 is switched to the key position M2 with the key, the changed code corresponding file expansion memory 52 is set with the hard code "1020" of the key position M2 as the search key.
Is searched and the corresponding business code “inspection” is read. Then, the inspection work program is selected and executed from the program file 30 of the hard disk device 20, and the inspection work is processed.

As described above, according to this embodiment, the ROM 1 is used in spite of the electronic cash registers of the same model.
For example, the key position M2 of the mode switch 6 can be easily set as the return registration work selection position or the inspection work selection position without modifying the control program in 2.

Therefore, for example, in a certain store, a general cashier capable of handling a key whose rotation range is limited to A1 may perform the return registration business mode, but prohibits the execution of the inspection business mode. Although the inspection business mode may be performed in another store, even if the operation of prohibiting the return registration business mode is prohibited, the electronic cash register of this embodiment causes an increase in cost. You can respond quickly without.

At each key position of the mode switch 6,
"Registration", "Return registration", "Inspection", "Settlement", "Settings"
If a sticker indicating the business name such as is attached, the change can be dealt with easily.

In the above embodiment, the code-corresponding file 40 is set in the hard disk device 20 and is expanded in the code-corresponding file expanding memory 52 at the time of start-up, but it is set in advance in a floppy disk, a memory card or the like. You may make it expand | deploy in the code corresponding file expansion memory 52 at the time of raising. In addition, the communication interface 15
The code-corresponding file 40 is set in the storage section of the host device connected by the line, the host device is inquired at the time of startup, the code-corresponding file 40 is read, and the code-corresponding file expanding memory 52 is expanded. Good.

In addition, various modifications can be made without departing from the scope of the present invention.

[0046]

As described above in detail, according to the present invention, a code-corresponding file in which business codes for specifying various business modes such as registration and settlement are set for each hard code corresponding to each key position of the mode switch is created. If the hard code corresponding to the current key position of the mode switch is read by reading from the outside and read into the memory, the code corresponding file is searched for and the corresponding business code is read, and the corresponding business code is found. Since the application program of the business mode to be executed is selected and executed, the control program is changed to the correspondence relationship between the key position of the mode switch operated by the key and the business mode selected at the key position. It is possible to replace it arbitrarily without needing to do so, and it is possible to easily realize the execution restriction of the work desired by the user by properly using the key. It is possible to provide a shoe register.
