Description

The present invention relates to an input device having a compulsory function such as an ECR (electronic cash register).

[Prior Art] Conventionally, in ECRs having a compulsory function, the compulsory is applied either before registration is started or after registration is completed.

That is, in the case of the call before the registration starts, for example, in the case of the <customer number> button compulsory, the registration process cannot be performed unless the customer number is input.

On the other hand, if you call after registration, for example, <tax / service>
In the case of compulsory, the input operation of the <cash / deposit> button cannot be performed unless the <tax / service> input operation is performed.

[Problems to be Solved by the Invention] As described above, in the related art, since the compulsory is applied only before the start of the registration process or after the registration, it is said that the compulsory is applied under a predetermined condition during the registration. Such a special case, for example, the subtotal amount is 1
It is very inconvenient because you cannot do a compulsory such as giving a discount when the amount exceeds 10,000 yen.

In addition, if the compulsory function is provided, the compulsory must be operated even when it is not actually needed, and thus there is the complication of unnecessary key operation.

An object of the present invention is to limit a key input after a specific key to a plurality of key codes stored in advance corresponding to a specific key when a condition stored in advance corresponding to the specific key is satisfied, An error processing is performed when a key code other than a plurality of key codes is input, so that the key input after a specific key can be limited to a preset key sequence.

[Means for Solving the Problem] The means of the present invention is to provide a key code of a specific key, a condition for limiting the input corresponding to the specific key, and a key input when the condition is satisfied. Condition storing means for storing a key sequence including a plurality of key codes; key determining means for determining whether or not the input key is the specific key stored in the condition storing means; When the key is discriminated, the condition corresponding to the specific key is read out from the condition storing means, and the condition discriminating means for discriminating whether or not the condition is satisfied, and the condition discriminating means satisfies the condition. When it is determined that a plurality of key codes corresponding to the specific key are read from the condition storage means, the plurality of key inputs after the specific key are read. It is limited to the key code, and key input limiting means for performing an error process when a key code other than the plurality of key codes is input.

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

When a key is input, the key determination means determines whether or not the input key is the specific key stored in the condition storage means, and when the specific key is determined, the condition determination means causes the condition storage means to output the specific key. The condition corresponding to is read and it is determined whether or not the condition is satisfied.

When the condition determining unit determines that the condition is satisfied, the key input limiting unit reads a plurality of key codes corresponding to the specific key from the condition storing unit, and a plurality of key inputs after the specific key are read. The key code is limited to the above key code, and error processing is performed when a key code other than the plurality of key codes is input.

[First Embodiment] A first embodiment will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a circuit diagram of an ECR (electronic cash register). The input unit 1 is set to power off, registration, setting, settlement, and inspection modes. Mode key 1A, Numeric key 1B, Department key
1C, tax / service key 1D, clear key 1E, customer key 1F, subtotal key
1G, cash / deposit key 1H,%-key 1I,% + key 1J, and other function keys 1K are provided respectively, and the output of each key is input to CPU 2 for processing. This CPU2 is a circuit that controls all the operations of this ECR.
In addition to A and control unit 2B, this time the key code is set A
Register, B register where search key code is set,
C register to set condition data, D register to set condition flag, E register to set input data such as subtotal, a register to set address,
An a'register is provided.

RAM 3 is composed of a total memory 3A and a key sequence memory 3B, and a key sequence of the compulsory function is preset in the key sequence memory 3B.

The ROM 4 is a memory in which key operation procedures other than the key sequences set in the key sequence memory 3B are fixedly set.

In addition to the CPU 2, a drawer 5, a printing unit 6, and a display unit 7 are also provided.
Are connected.

Next, the operation will be described with reference to FIGS. 2 and 3. Address 1 of area M1 to M5 of key sequence memory 3B
As shown in Fig. 2, the key code is "00".
2 ”, the character code is“ subtotal ”, the next key code is“ [1] [0] [% −] [cash / deposit] [E] ”,
It is assumed that the condition flag “0” and the condition data “subtotal ≧ 10000” are preset.

Also, in address 2 of areas M1 to M5 of the key sequence memory 3B, the key code is "002", the character code is "subtotal", and the next key code is "[tax / service].
[Cash / deposit] [E] ”, condition flag“ 0 ”, and condition data“ subtotal / customer ≧ 2500 ”are preset.

Now, when a customer makes a purchase and performs the registration process, the numeric keys 1B and department keys 1C are operated until the subtotal key 1G is operated, so steps A1 and A2 in the flowchart of FIG. 3 are operated. , A3 are repeatedly executed. When the subtotal key 1G is operated, the calculation unit 2A calculates the subtotal amount and sets it in the E register. Then, from step A2 to A4, the a register is incremented by 1 to become "1", and then the key sequence memory is stored in the B register in step A5.
The data "002" of address 1 in the area M1 of 3B is set in the B register, and then it is compared with the key code "002" in the A register in step A6. Since they match, YES is returned to step A8 and the address is set. The condition flag “0” of the area M4 of 1 is set in the D register, and then it is determined in step A8 whether or not the D register is “1”, the result is NO and the process proceeds to step A9. Condition data “subtotal ≧ 10000” is set in the C register, and then step A
At 10, the data in the C register is compared with the subtotal amount in the E register. And the subtotal amount of this time is 10,000
If it is equal to or more than the circle, the process proceeds to step A11, and the next key code of the area M3 of address 1 is the area M of address 1
6, transfer set to M7, M8, M9 sequentially. Then, in step A12, the condition flag "1" is set in the area M4 of address 1, in step A13, "6" is set in the a'resistor, and in step A14, the data of M (a ') is set to B. It is set in the register. Also, the subtotal is now 10
Since it is over 000 yen, after operating the subtotal key 1G, "10,%
-The key operation of "cash / deposit" is performed. In this case, wait until the number "1" is entered, and when the number is entered, step
In A15, that is judged, the key input code is set in the A register, and the process proceeds to step A16.

Then, in step A16, the contents of the A register and the contents of the B register are compared, and if they match, the process proceeds to step A17, where the process based on the data input by the key is executed, and the process proceeds to step A19, where there is a mismatch. If there is, error processing (step A18) is executed and then the process returns to step A1. Also, in step A19, the a'register is incremented by 1 to become "7" and M
The contents of 7 are set in the B register (step A20), and the process proceeds to step A21. Then, in step A21, it is determined whether or not the content of the B register is the end code, that is, it is determined whether or not a series of predetermined key operations after the subtotal key operation are completed, but in this case, it is not the end code. The process proceeds to step A15, and the same processes as described above are sequentially executed.
Then, when it is determined that the next key code is the end code in step A21, the process proceeds to step A22 and M6
~ Clear the contents of Mn and proceed to step A4, sequentially search the key sequence memory 3B for the same key code as the entered key code, and also the condition flag indicating that it was previously entered. If is not set,
The above processing is sequentially executed.

If it is determined in step A6 that the key codes of the A register and B register do not match, step A23
Then, it is determined whether or not the search address of the key case memory 3B is the final address, and if it is not the final address, the process proceeds to step A4, and if it is the final address, the process proceeds to step A24. If no flag is set in M4 (not shown), a normal function process is executed to proceed to step A25, where the contents of a, a'register and M4 are cleared and step A1 Return to.

On the other hand, when the subtotal amount is 10,000 yen or less, the process returns from step A10 to step A4, and steps A5, A6 and A23 are repeated until the data in the a register becomes n, and the process ends.

Also, if the subtotal amount of a customer is 2500 yen or more, as shown in Address 2 in Fig. 2, after the subtotal operation, [tax /
If you perform a [Bong] or [Cash / Deposit] operation, when the a register becomes "2" by the above-mentioned operation, step
A5, A6 are executed, and further steps A7, A8, A9, A10, A1
1, A12, A13, A14, A15, A16, A17, A19, A20, A21, A1
5, A16, A17, A19, A20, A21, A22 are similarly executed, respectively, and the compulsory is executed.

On the other hand, if it is 2500 yen or less, steps A4, A5, A6, A23 are a
The process is repeated until the register becomes n, and the process ends.

Second Embodiment Next, a second embodiment will be described with reference to FIGS. 4 to 8.

FIG. 4 shows a circuit diagram thereof, but the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Thus, the input section 1 is newly provided with an arrangement key 1L for instructing execution of the arrangement process. The arrangement code of area M3 is set in the D register.

Next, the operation will be described. Now, as shown in FIG. 5, it is assumed that data for compulsory as shown in the figure is preset in each area M1 to M4 of addresses 1 and 2 of the key sequence memory 3B. Then, this data setting operation may be performed as shown in FIG. That is, the mode key
1A to enter setting mode, then cash / deposit key 1H, subtotal key
When 1G, the 1 and 0 keys of the numeral keys 1B, the% -key 1I, and the arrangement key 1L are operated, the condition data and the like are preset in the address 1 as shown in FIG. The same applies to the address 2.

In addition, when clearing such preset data, in this setting mode, the cash / deposit key 1H, subtotal key
1G, the 1 and 0 keys of the numeric keypad 1B, the% -key 1I, and the clear key 1E may be operated sequentially.

Next, when the key operation shown in FIG. 7 (1) is performed for registration, steps B1, B2, B3 of the flowchart in FIG. 8 are repeated until the cash / deposit key 1H is operated, and the data is stored. To enter. And when you operate the cash / deposit key 1H, step
From B2 to step B5, the a register is incremented by 1 to become "1", then the key code "001" of the area M1 of the address 1 is set in the B register in step B6, and next in the step B7 the A register this time. Key code of "001"
Is compared with YES, the process proceeds to step B8, condition data subtotal ≧ 10000 of area M4 is set in the C register, and then in step B9, it is set in the E register based on the data in the C register. Subtotal data 15
Compared to 00 yen. Then, since the condition is not satisfied, the routine proceeds to step B12, where it is judged whether or not the a register is n, and when it is NO, the routine returns to step B5 and the a register becomes "2".

Then steps B6, B7 and B8 are executed, and at B9 address 2
It is determined that the condition data subtotal / customer ≧ 2500 is not satisfied, and the process returns to step B5 via step B12. After that, the above-described operation is repeated until the a register becomes n.

On the other hand, if YES in step B12, the process proceeds to step B13, the a register is cleared, and the process proceeds to step B4 to execute each function process (in the embodiment, the tightening process by the present / deposit key) and then return to step B1.

Further, when the key operation example as shown in FIG. 7 (2), that is, when the subtotal of one customer has operated the cash / deposit key 1H for more than 2500 yen, the condition data of address 2 is set in step B9. It is determined that the condition is satisfied, and the process proceeds to step B10. And area M3 (address 2) data [subtotal] [tax / service] [E]
Are transferred to the D register, and the arrangement process based on the D register is performed in step B11. Then, the process proceeds to step B12.

Further, when the registration as shown in FIG. 7 (3) is performed, that is, when the condition data of the address 1 is satisfied, steps B9, B10 and B11 are executed, and the process proceeds to step B12.

Further, as shown in FIG. 7 (4), also in the case of the registration processing satisfying both condition data of the addresses 1 and 2, the above-mentioned steps B9 to B11 are respectively executed, and the process proceeds to step B12. In the second embodiment as described above, when the compulsory function operates according to the conditions during registration, the key code set beforehand is read and the arrangement processing is performed. There is an advantage that the key input error can be prevented.

[Effects of the Invention] According to the present invention, when a condition stored in advance corresponding to a specific key is satisfied, a plurality of key codes stored in advance corresponding to the specific key for key input after the specific key Is limited to key sequences including, and error processing is performed when a key code other than the plurality of key codes is input, so that necessary key input limitation can be set in advance and unnecessary key operation need not be performed. There is an advantage.
