Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register or a POS (Point of Sales) terminal. More specifically, this article relates to a product sales data processing device that allows operation modes to be selected by key operation. [Prior Art] Product sales data processing devices, such as electronic cash registers and POS terminals, operate in one of multiple operating modes, such as "setting,""suspension,""registration,""inspection," and "settlement" modes. When a mode is selected, processing based on the selected operation mode is executed. Conventionally, as a configuration for selecting an operation mode, a sixth
The configuration shown in Figures and Figure 7 is adopted. In these figures, 1 is a key switch owned by each operator or store manager, and 2 is a key switch placed on the keyboard.
. . . A switch section 3 which is switched to a position shown in FIG.
This is an input circuit that sends information to the PU.

Each operator or person in charge inserts the key switch 1 in his or her possession into the switch section 2 and rotates it to the desired operating mode position. Then, the signal corresponding to the switching position of the switch section 2 or the input time F! Since the information is given to the CPU through @3, the CPU executes processing based on the operation mode selected by the key switch 1. Note that the above [setting j] refers to the task of setting the date, product name, etc. in the setting area in the storage unit. Furthermore, "Suspension J" refers to a locked state in which all tasks cannot be executed.

Furthermore, "registration" refers to the process of storing the price of sold products in the storage unit and printing the results on receipts and journals. In addition, "inspection" refers to the task of printing out the total sales amount, points, etc. cumulatively stored in the storage unit through "registration". Also,"
"Settlement" refers to the task of printing out the total sales amount, points, etc. cumulatively stored in the storage section by "registration" at the end of the day's work, and clearing the contents of the storage section.

[Problem to be solved by the invention] By the way, as this type of product sales data processing device becomes more sophisticated, it is required to reduce costs and make it more compact6. If there is a key switch 1, a switch unit 2, an input circuit 3, etc., the cost will be high. Furthermore, since the switch section 2 must be placed on the keyboard in consideration of operator operability, it is necessary to secure a space for installing the switch section 2 on the keyboard. This is a problem that not only limits the demand for compactness but also limits the degree of freedom in design. Moreover, each operator or store manager must pull out the key switch 1 from the switch section 2 and carry it with him after finishing his work. Therefore, security problems arise such as the key switch 1 being lost or stolen while being carried. The purpose of the present invention is to provide a product sales data processing system 1 that can solve all of the conventional problems, reduce costs and make it more compact, and also solve security problems. be. [Means for Solving the Problem] In the invention described in claim 1, in a product sales data processing device that executes processing based on an operation mode selected from a plurality of types of operation modes, a mode switching declaration key and a A code input key for inputting a code corresponding to each operation mode; a storage means storing codes corresponding to each operation mode; and a code input key provided that the mode switching declaration key is operated. a determining means for determining whether the code input by the key matches any code stored in the storage means, and the determining means determines whether the code input by the code input key matches any code stored in the storage means; The present invention is characterized by comprising a mode switching means for setting an operation mode corresponding to the code on the condition that it is determined that the code matches the code.

Further, in the invention set forth in claim 2, in the invention set forth in claim 1, the determining means may be configured to operate the code input key on the condition that the mode switching declaration key has been operated a predetermined number of times in succession. It is characterized in that it is determined whether the input code matches any code stored in the storage means. [Function] In the invention described in claim 1, when a code is input using the code input key on the condition that the mode switching declaration key is operated, either that code or one of the codes stored in the storage means is input. It is determined whether the code matches or not. Here, if it is determined that the code matched with either the code input by the code input key or the code in the storage means is set to the operation mode corresponding to that code. In other words, the operation mode can be switched to the one corresponding to the code entered by the code input key, which eliminates the need for a conventional key switch, switch section, input circuit, etc., which reduces costs and allows the switch section to be placed on the keyboard. It is possible to make it more compact since there is no need to place it in the Moreover, since the operating mode can be switched by a code input using a code input key, use by a third party other than a specific person such as an operator or a person in charge can be prohibited. At the same time, since there is no need to carry a key switch, security problems such as loss of the key switch or theft can be solved.

Further, in the invention described in claim 2, on the condition that the mode switching declaration key is operated a predetermined number of times in succession, the code inputted by the code input key is matched with any code stored in the storage means. Since it is determined whether or not they match, that is, the operating mode is switched by double checking the number of operations of the mode switching declaration key and the code input using the code input key, so higher security can be ensured.

[Example] Hereinafter, an example in which the present invention is applied to an electronic cash register will be described based on the drawings.

Figure 1 shows the circuit configuration of the electronic cash register of this embodiment. In the figure, 11 is a CPU. C
The PUII has a ROM 1 that stores programs related to operation modes such as "setting", "pause", and "registration", "inspection", and "payment" via the address/data path 12, etc.
3. RAM 1 for storing sales data etc. 4. Keyboard control circuit 17, display control circuit 18 and I/019
etc. are connected to each other.

A keyboard 22 is connected to the keyboard control circuit 17, and a display section 23 is connected to the display section control circuit 18. Further, a printer 25 is connected to the I/019 via a printer drive circuit R24, and a drawer 27 is also connected via a drawer opening device 26. The keyboard 22 has r
oo,, rQ, - Number 31 as a code input key up to "9", clear JIr- that also serves as a mode switching declaration key
32, Department. In addition to 3r-33, there are 34 subtotal keys and deposit/
Current total -'r-35 etc. are arranged respectively. The 1 number key 31 is used to input the price and number of items, etc.
It is used to enter the code corresponding to each operation mode such as ``Setting'', ``Pause'', ``Registration'', etc. In addition, as shown in FIG. 3, the RAM 14 includes, in addition to an area 40 for storing sales data and the like, a numeric buffer 41 for temporarily storing 1-digit data input using the numeric key 31, and a clear A counter 42 that remembers the number of consecutive operations of the key 32, and code areas 43A to 43A that store in advance codes corresponding to each operation mode such as "setting", "pause", "registration", etc. 43E
and a plurality of flags FO to F5 are respectively provided. Here, the mode switching declaration flag FO is the counter 4.
It is set when the count number 2 reaches "5", and is reset when any of the other flags F1 to F5 is set. Further, the setting mode flag F1 = suspension mode flag F2, registration mode flag F3, inspection mode flag F4, and payment mode flag F5 are set by pressing the number key 31 after the clear key 32 is operated five times in succession.
The code entered by is code area 43A~43
When the code matches any code stored in E, only the flag corresponding to that code is set, and other flags are also set. Further, the CPU II executes processing in each operation mode according to a program stored in the ROM 13. That is, the process of the operation mode corresponding to the set flag among flags F1 to F5 is executed. Also, in each operation mode, when the clear key 32 is operated,
Execute the process shown in the flowchart shown in Figure 4. Also,
When the number key 31 is operated, the process of the flowchart shown in FIG. 5 is executed. In addition, in "pause" mode,
Only operations of clear='r-32 and number key 31 are accepted.

Here, the CPU 11 and the ROM 13 constitute the determining means and mode switching means of this embodiment. In other words, the determining means determines that if the clear key 32- has been operated a predetermined number of times, in this case 5 times, the code inputted by the number -'r-31 is in the code areas 43A to 43E. Determine whether it matches any code stored in . In addition, the mode switching means is
On the condition that the determining means determines that the code inputted by the numeral -1r-31 matches one of the codes in the code areas 43A to 43H, the operation mode corresponding to that code is set. ．． Next, the operation of this embodiment will be explained.

When the power is on, it is set to "hibernation" mode. When changing from this "pause" mode to another mode, or when changing from "setting", "registration", "inspection", or "payment" mode to another mode,
First, after operating the clear key 32 five times in succession, enter the code corresponding to the mode you want to change using the digit JIr-31. The CPU II executes the process of the flowchart shown in FIG. 4 every time the clear key 32 is operated. First, in step (hereinafter abbreviated as ST) 1, the counter 42 is incremented by +1, and then the process proceeds to ST2, where it is determined whether the count number of the counter 42 has reached "5". If the count number of the counter 42 has not reached "5", the process advances to ST3 and normal clearing processing is performed. On the other hand, if the count number of the counter 42 has reached "5", ST
Proceed to step 4 and set the mode switching declaration flag FO. Therefore, when the clear key 32 is operated five times in succession, the mode switching declaration flag FO is set. Further, each time 1 number data is input using the numeric key 31, the process of the flowchart shown in FIG. 5 is executed. First, STII
Determine whether the mode switching declaration flag FO is set. If the mode switching declaration flag FO is not set, the process proceeds to ST12, where the count number of the counter 42 is cleared to "0", and then the process proceeds to ST13, where 1 number processing, that is, storing the numeric data in the numeric buffer 41,
It is displayed on the display section 23.

On the other hand, if the mode switching declaration flag FO is set, it is determined in ST14 to ST18 whether the input digit data (code) matches any of the codes stored in the code areas 43A to 43E. Here, if the input one number data (code) matches the setting code stored in the code area 43A, the process advances to ST21, sets the setting mode flag F1, and then proceeds to ST22, setting the setting mode flag other than F1. After resetting the flags F2 to F5, the process proceeds to ST31, where the counter 42 is cleared and the mode switching declaration flag FO is reset. In other words, switch to configuration mode. Further, if the input number data (code) matches the pause code stored in the code area 43B, the process advances to ST23 and sets the pause mode flag F2, and then the process advances to ST24 to flag other than the pause mode flag F2. Fl. After resetting F3 to F5, the process proceeds to ST31, where the counter 42 is cleared and the mode switching declaration flag FO is reset (6), that is, the mode is switched to the rest mode.

Also, if the input number and data (code) match the registration code stored in the code area 43C, ST2
Proceed to step 5, set the registration mode flag F3, and then
Proceed to T26 and register flags Fl other than registration mode flag F3,
After resetting F2, F4, and F5, proceed to ST31, clear the counter 42, and set the mode switching declaration flag F.
Reset O. In other words, switch to registration mode. Also, input numeric data (code) or code area 4
If it matches the inspection code stored in the 3D, proceed to ST27, set the inspection mode flag F4, and then proceed to ST2
Proceed to 8 and check flags F1 to F3 other than inspection mode flag F4
, After resetting F5, proceed to ST31 and counter 42
and reset the mode switching declaration flag FO.

In other words, switch to inspection mode. In addition, the entered number data (code) is stored in the payment code area 43E. - If it matches the code, ST2
Proceed to 9 and set the payment mode flag F5, then proceed to S
Proceed to T30 and set the payment mode flag F1 to other than the settlement mode flag F5.
After resetting F4, proceed to ST3 1 and counter 42
and reset the mode switching declaration flag FO. In other words, switch to payment mode.

In this way, when any of the flags F1 to F5 is set, the CPU II
Executes processing based on the operation mode corresponding to 1 to F5. Therefore, according to this embodiment, the clear key 32 and the set number -1
Since the operating mode is changed by operating the r-31, there is no need for a key switch, switch section, input circuit, etc. as in the past, resulting in lower costs, and the switch section does not need to be placed on the keyboard. It is also possible to make it more compact. Especially clear key 3
2 and the numeric key 31, which are included in ordinary electronic cash registers, there is no need to provide any special keys. Also from this point of view, it is possible to make it more compact.

Further, since the operating mode can be changed by a code input using the numeric key 31, use by third parties other than the operator or store manager can be prohibited. At this time, only the codes corresponding to the "pause" and "registration" modes should be communicated to the operator, and the other codes should be known only to the store manager. Switching to the mode can be regulated. At the same time, since there is no need to carry a key switch, security problems such as loss or theft of a key switch can be eliminated. In addition, only when the clear key 32 is operated 5 times in a row, the operation mode is set to a state where switching is possible.
Since the operating mode is switched by double checking with the code entered by 1, higher security can be ensured. In addition, in the above embodiment, the clear key 3
2 is also used as the mode switching declaration key, but the mode switching declaration key is not limited to this, and may be any key that does not immediately start a specific operation when operated only once. Alternatively, a special mode switching declaration key may be provided, and the operating mode may be set to a state in which switching is possible on the condition that this key is operated once.

Further, the code input key is not limited to the number -1r-31 described in the above embodiment, but the department key 33 may be used, for example.

In addition, in the above embodiment, apart from the keyboard 22,
If a keypad having a mode switching declaration key, numeric keys, etc. is connected to the CPU 1 via a cable, it is possible to switch modes by key input from the keypad. In this way, even if the person in charge of the store wants to switch to a mode other than "pause" or "registration," he can do so without the operator seeing the key operations, so security can be ensured.

Further, in the above embodiment, an example was explained in which the present invention was applied to an electronic gear/social register, but the present invention can also be applied to a posi terminal or the like.

[Effects of the Invention] As described above, according to the present invention, the following effects can be achieved. Since the keyboard can be selected, the key switch, switch section, input circuit, etc. that are required in the past are no longer required, resulting in lower costs, and the switch section does not need to be placed on the keyboard, making it more compact. be. Moreover, since the operating mode can be switched by a code input using a code input key, use by a third party other than a specific person such as an operator or a person in charge can be prohibited. At the same time, since there is no need to carry a key switch, security problems such as loss or theft of the key switch can be resolved. Further, in the invention described in claim 2, when the mode switching declaration key is operated a predetermined number of times in succession, either the code input by the code input key or the code stored in the storage means is output. Since it is determined whether or not they match, higher security can be ensured.
