DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a point-of-sale (POS) terminal, and more particularly to a POS terminal having improved key operability.

[0002]

2. Description of the Related Art Many POS terminal keyboards have a specific function, such as a setting mode using a mode lock and valid keys that can be input during a certain operation.

Conventionally, as shown in, for example, Japanese Patent Application Laid-Open No. 5-35755, an input key is analyzed, but if the key is incorrect, it is displayed that the input key is error and the error is released. Operation is required by the operator.

FIG. 6 is a block diagram showing a conventional example disclosed in the above publication.

In this POS data analysis method, an input device 11 for inputting data for performing a process and a state matrix section 12 for searching for a process to be executed in a next state based on current input data. A matrix search unit 13 for searching the state matrix unit 12 for processing information, a processing control unit 14 for controlling each business processing based on the processing information searched by the matrix search unit 13, and a business processing unit for performing a POS business 15.

Next, the operation of this conventional example will be described. First, the matrix search unit 13 searches the state matrix unit 12 based on the current state waiting for input and the input data from the input device 11. This state matrix part 12
Has information on a process to be executed and information indicating what input data waiting state is to be entered after the process.
The processing information searched by the matrix search unit 13 is notified to the processing control unit 14, and the processing information returns to the matrix search unit 13 and becomes information for the next search. And
The processing control unit 14 controls the business processing unit 15 based on the searched processing information and performs business processing of the POS terminal.

[0007]

The problem is that the operation takes time due to erroneous key input.

[0008] The reasons are time loss during introduction and maintenance, inconvenience to customers at the time of sales registration, a bad impression, and a reduction in the efficiency of cash register operations during congestion.

SUMMARY OF THE INVENTION It is an object of the present invention to improve operability by operating only those keys for which a pressed key is valid.

[0010]

The POS terminal device according to the present invention is characterized in that after inputting a key, the validity of the pressed key is determined by referring to a table corresponding to the position of the mode lock or the type of the immediately preceding pressed key. And

A POS terminal device of the present invention includes a POS keyboard for inputting information necessary for operation, a mode lock, a display device, a control device for performing processing,
A printing device, a first ROM storing a key code table search table, and a key code table stored therein.
And a second of the ROM that, by referring to the key code table lookup table, in the process currently being executed, the position of the key code table and then referenced with a combination according to the immediately preceding depressed key code Get
Said key code table search by referring to the key code table from the obtained position by the table to determine the validity of the depressed key, the key code entered by the keyboard is sent to the control device, said control device key When the code is received, the key code table search table stored in the first ROM is obtained by referring to the current processing corresponding to the mode different depending on the position of the mode lock and the immediately preceding pressed key code. state is stored in the second ROM based can refer to the previous Symbol key code table Ru Tei was, and compares the key code is pressed, where if there is a corresponding key code is pressed key code processing determined Are compared, and if so, execute the determined processing.If not, return to the key input processing and check the available keys. In the decision, if there is no corresponding key, while ignoring the key input, and wherein the return to the key input processing untreated without prompting.

Further, a touch panel that allows input by touching a screen is included, and a code corresponding to the key code can be assigned to the touch panel.

According to the key press error prevention method of the present invention, the key table search table (FIG. 2) is referred to by the processing being performed at the time after the key input, and the key code table (FIG. 3) is referred to by the referred value. Then, it has means for judging the validity of the pressed key. As a result, if the key is valid, the key is accepted.

The validity of the input key is determined by the RO of the POS terminal.
Judgment is made by referring to the table in M, and if the key is erroneously pressed, the key is invalidated. For this reason, it is not necessary to perform post-processing when the operator makes a mistake.

[0015]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of a POS terminal device according to a first embodiment of the present invention. The POS terminal device includes a POS keyboard 1 for inputting information (including an amount for registering sales) necessary for operating the device,
Mode lock 2, display device 3, and control device 4 for processing
, Printer 5, key code table search table,
And a ROM 6 storing a key code table and
And a RAM 7.

FIG. 2 shows a key code table search table 8 indicating a location to which the key table refers. By referring to this table, in the process currently being executed, the position of the next key code table to be referred to is obtained in combination with the immediately preceding pressed key code.

FIG. 3 is a key code table 9 showing usable key codes. The key code table 9 is referred to from the position (state) obtained by the key code table search table 8 to determine the validity of the pressed key.

Next, the operation of this embodiment will be described in detail. FIG. 4 is a flowchart showing the operation of the POS terminal device of FIG.

Input via keyboard 1 (step S1)
The key code is sent to the control device 4. Control device 4
Different modes are stored pressed key code immediately preceding the current process corresponding to the ROM 6 based on (set, registered, settling included) Tei Ru keycode table by Upon receiving the key code, the position of the mode lock 2 The search table is referenced (step S2). Then reference is stored in the ROM 6 based on a state obtained Tei Ru key code table in step S2 performed (step S3), and performs the comparison with the key code is pressed (Step S4). If there is a corresponding key code, that is, if there is a usable key code,
It is determined whether the pressed key code has been determined (finished) (step S5). If so, the determined processing is executed (step S6). If not, the flow returns to the key input processing (step S1). .

If it is determined in step S4 that the key is not usable, if there is no corresponding key, the input key is ignored (step S7). Is displayed, but the process returns to the key input process (step S1) without displaying the message.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 5 is a block diagram of a POS terminal according to a second embodiment of the present invention. A touch panel 10 that allows input by touching the screen with a finger or a pen or the like is included.

Next, the operation of the second embodiment will be described.

In this embodiment, the operation is the same as that of the first embodiment by assigning a code corresponding to the key code in the first embodiment to the touch panel.

[0026]

As described above, according to the present invention, the validity of input keys is determined in each business process and invalid input keys are invalidated, so that the reliability of high-speed key input can be improved. This is effective in shortening the time by eliminating the error cancellation processing at the time of erroneous input.
