Turn to And transmission control means for transmitting the data.

[Industrial applications]

The present invention relates to a POS terminal, and more particularly to a POS terminal that saves internal data in the event of a failure to a higher-level terminal controller or the like.

[Conventional technology]

Nowadays, so-called POS systems that connect a plurality of POS terminals to a terminal controller in various sales operations, collectively perform data processing, and increase the efficiency of operations are widely used.

In the case of a POS terminal of this POS system, for example, when a failure such as a key input becomes impossible,
It is common that the data in the internal memory is sent to the terminal controller, and the terminal controller analyzes the contents of the fault.

At this time, the internal data was sent to the terminal controller when the power was turned off and the power was turned on again after a failure occurred.

[Problems to be solved by the invention]

By the way, in the above-described conventional method, when the power is turned off once and the power is turned on again, the internal data is always saved to the terminal controller.

Therefore, even when the operation of one day is completed and the power is turned on at the start of the operation of the next day, the internal data is saved. However, in this case, since no failure has occurred, there is no need to save the internal data to the terminal controller. Similarly, when the power is turned off even if no failure has occurred, the internal data is saved the next time the power is turned on.

Therefore, the conventional device has a problem that once the power is turned off, the internal data is unconditionally saved to the controller when the power is turned on next time.

The present invention has been made in view of such a point, and an object of the present invention is to provide a POS terminal capable of saving internal data only when a failure occurs, for example.

[Means for solving the problem]

FIG. 1 is a principle block diagram of a POS terminal according to the present invention.

In the figure, a first storage unit 111 stores and holds data during operation.

The second storage unit 113 stores and holds a flag indicating whether or not a key input operation is being performed.

The setting unit 115 determines whether or not a key operation is being performed.
A flag is set in the second storage means 113.

Although not shown, a means for temporarily turning off the power when a failure occurs is provided.

When the power is turned off and then turned on again, the transfer control means 117 checks the recorded contents of the second storage means, and if the flag indicates that a key input operation is being performed, Then, the data stored in the first storage unit 111 is transferred to the host device.

Therefore, as a whole, when a failure occurs and the power is turned off after the information set in the second storage unit 113 indicates that the key input operation is being performed, and then the power is turned on,
The data stored in the first storage unit 111 is configured to be transferred to a higher-level device.

[Action]

The first storage unit 111 stores data during operation without being erased even when the power is turned off. Further, in the second storage unit 113, a graph is set according to whether or not a key input operation is being performed by the setting by the setting unit 115. When the power is once turned off and then turned on again, the recorded contents of the second storage means 113 are checked,
When the flag indicates that the key input operation is being performed, the transfer control unit 117 transfers the data stored in the first storage unit 111 to the host device.

According to the present invention, when the second storage unit 113 indicates that a key input operation is being performed, a failure occurs and the power is turned off;
Then, when the power is turned on, the data in operation stored in the first storage unit 111 is transferred to the host device, so that the internal data can be saved only when a failure occurs, for example.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 shows a configuration of a POS terminal according to one embodiment of the present invention.

I. Correspondence Between Embodiment and FIG. 1 Here, the correspondence between the embodiment of the present invention and FIG. 1 will be described.

 The first storage unit 111 corresponds to the work area 215.

 The second storage unit 113 corresponds to the flag 213.

 The setting unit 115 corresponds to the CPU 210.

 The transfer control unit 117 corresponds to the CPU 210.

An embodiment of the present invention will be described below assuming that there is the above correspondence.

II. Configuration of the Embodiment In FIG. 2, the POS terminal 200 has a central processing unit (CPU) 210 for performing overall control, a work area 215 for storing data during operation of the device, and whether a key input operation is being performed. Memory 211 including a flag 213 and the like in which information on whether or not is set
, A line control driver / receiver 217 for controlling communication with a terminal controller (not shown), a display 219 for displaying results and the like, a keyboard 221 for inputting data and instructions, and printing the results and the like. And a printer 223.

CPU 210, memory 211, line control driver / receiver 217,
The display 219, the keyboard 221, and the printer 223 are all connected to the bus. However, the display 219, the keyboard 221, and the printer 223 are via an interface (not shown).

The line control driver / receiver 217 is connected to a terminal controller on the center side via a line.

The work area 215 is set by the CPU 210 so as to be “1” when a key input operation is being performed and “0” when a key input operation is not being performed.

In addition, even if the POS terminal 200 or the power is turned off, the information of the flag 213 and the work area 215 are not deleted because the power is backed up independently.

III. Operation of Embodiment FIG. 3 shows an operation procedure relating to data saving. FIG. 4 shows a temporal flow relating to data saving.

The operation of the embodiment will be described below with reference to FIGS.

First, the task is started and the terminal is turned on (step 311). In this state, the key 213 has not been input yet, so the flag 213 is “0”.

Next, the screen on the display 219 is moved to the home position (step 312). Even in this state, the flag 213 is "0".

In this home position state, it is determined whether or not an instruction to end the work has been given from the keyboard 221 (step 313).

If the instruction to end the business is not issued (negative determination in step 313), key input in a transaction with the customer is started (step 314).

Next, it is determined whether a failure has occurred during the input in step 314 (step 315).

If no trouble occurs (negative determination in step 315) and the transaction is completed, the input is terminated (step 316),
It returns to the home position screen of step 312.

If a failure has occurred in step 315 (affirmative determination), the power is turned off once (step 317).

When the power is turned on again (step 318), the data stored in the work area 215 in the memory 211 is sent to the terminal controller via the line control driver / receiver 217 (step 319).

On the other hand, if an instruction to end the work is issued in step 313 (affirmative determination), the power is turned off (step 313).
320) Terminate the business.

According to the above operation procedure, as shown in FIG. 4, when the power is turned on at the start of a business day, the flag 213 is set to "0", so that the data in the work area 215 is not saved to the terminal controller. . On the other hand, if a failure occurs during the key input operation and the power is turned off, the flag 213 keeps “1”, so that when the power is turned on again, the data in the work area 215 is saved. .

IV. Summary of Embodiment As described above, in the memory 211, the flag 213 is set so as to be “1” during key input in a transaction with a customer and “0” when no key input is being performed. If the failure occurs and the power is turned off during the key input in the transaction of 即 ち, ie, when the flag 213 is “1”, the data in the work area 215 is saved to the terminal controller when the power is turned on thereafter.

However, when the power is turned on at the start of a business day, the flag
Since 213 is “0”, the data in the work area 215 is not saved.

Therefore, the internal data can be saved only when a failure occurs.

V. Modifications of the Invention In the above-described embodiment of the present invention, the flag as the second storage means is secured in the same memory as the work area of the first storage means. May be configured by hardware.

The setting means at that time is not limited to the software setting by the CPU.

Further, in "I. Correspondence between the embodiment and FIG. 1",
Although the correspondence between the present invention and the embodiments has been described, the present invention is not limited to this, and those skilled in the art can easily infer that there are various modifications.

〔The invention's effect〕

As described above, according to the present invention, when the power is turned on in a state where the second storage means indicates that a key input operation is being performed, the data stored in the first storage means during the operation is transferred to the host device. By transferring the data to the server, for example, the internal data can be saved only when a failure occurs, which is extremely useful in practice.
