Description

[Detailed Description of the Invention] The present invention is a POS (point-off sales) system, a banking system, etc., which accumulates amount data and quantity data input at the time of a transaction on a cumulative device (hereinafter referred to as a terminal device or terminal) side, and , relates to an improvement in processing when so-called online/offline switching is performed at a terminal in a system in which data is also collected and aggregated by a central device.

In general, a system is known in which data input on the terminal device side is accumulated, and data input on the terminal device is also collected and totaled on the center device side.

However, in such a system, for example, if the center device becomes malfunctioning, or if the operator is to be trained, or if the terminal is to be maintained, inspected, or tested, it is difficult to connect from a state where it is logically connected to the center side. A so-called online/offline switching is being performed to disconnect the device.

When performing such a switch, the cumulative total of the terminal device, the so-called transaction counter, is usually outputted at the time of switching from online to offline, and also outputted when switching from offline to online, and recorded by a printer etc. It is possible to confirm and identify the data left in the offline state.

However, with conventional devices, just before switching to offline mode or online mode on the terminal device side, a complicated operation different from the operation when performing a normal transaction is required to output the cumulative data of the transaction counter. ing.

Therefore, if the operator forgets to check the transaction counter data and enters the next transaction data, the
It has drawbacks, such as the fact that it is difficult to distinguish between cumulative data in online mode and cumulative data in offline mode.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a mode switching processing method for a data accumulating device that eliminates the need for outputting a transaction counter.

In order to achieve the above object, the present invention detects that the online/offline mode changeover switch is switched and automatically outputs transaction counter data. The details will be explained based on.

In the figure, KB is a keyboard, IR is an input register, A is an addition section, SL is a selector, TR#0 to TR#i are transaction counters, RD is a reading section, PC is a print control section, TC is a transmission control section, M is the mode changeover switch, ■ is the inquiry key, 01
, 02 is the OR gate, CC is the center device, and F is the file.

The configuration of this embodiment will be explained below.

The data input section consists of a keyboard KB, through which data is input.

The data input from the keyboard KB is accumulated by the accumulator.

This accumulation section consists of an input register IR, an adder A, and a selector S.
L and transaction counter TR,='O~T'R,ji.

The adder A adds the data in the input register IR, and the selector SL stores the added data in the transaction counters TR7'O to TR,='i.

The print control unit PC and printer PR constitute an output unit,
Input register IR or transaction counter TR〆0~TR
Output the data stored in /i.

Furthermore, the data stored in the input register IR is transferred to the center device CC by the transmission control section TC.

In addition, the mode switching switch 7CHM specifies switching between online and offline, the switching detection section DT detects the switching of the mode, and the reading section RD detects the transaction counter TR10~
Data stored in TR/i is sequentially read out and output by printer PR.

Next, the operation of this embodiment will be explained.

First, normal operation, that is, online mode will be explained.

In the online mode, switch M outputs a signal at logic "0" level.

This places the transmission control section TC in an operable state.

A data type code (written as code) and data to be accumulated (collectively referred to as input data) are input from the keyboard KB, and are accumulated in the input register IR.

The data accumulated in the input register is supplied to the print control section PC via the transmission control section TC and the OR gate 01.

As a result, the input data is transferred to the center device CC and registered in file F. For example, one month's cumulative total by product, etc.
Used for large cumulative total processing.

Further, the data supplied to the print control unit PC is supplied as is to the printer PR, and is printed out as a receipt or authentication data.

On the other hand, among the input data accumulated in the input register IR,
The type code portion is supplied to the selector SL, and the cumulative data portion is supplied to the adder A.

The selector SL selects transaction counters TR#0 to TR#i according to the supplied type code part.
・Transaction counter T in which the corresponding type code is stored
R#m is extracted, and the data accumulated in the accumulated data section is further supplied to the adding section A.

Adder A further accumulates the data portion of register IR with respect to the accumulated data passed from selector SL, and adds it to selector SL.
Deliver to.

The selector SL updates the cumulative data portion of the previously selected transaction counter TR+m with the cumulative data delivered from the adding unit A.

Similarly, transaction counter TR#O~ for each type code
The cumulative data accumulated in TR#i is updated.

Next, when the mode changeover switch M is changed over, the changeover detection section DT detects the rise or fall of the mode changeover switch M, and activates the readout section RD to read.

Based on this, the reading unit RD reads out each transaction counter one by one, and passes this to the print control unit PC.

The print control unit PC supplies the received type code and cumulative data to the printer PR to print it.

This is done in the same way whether switching from online mode to offline mode or switching from offline mode to online mode.

However, when the transmission control unit TC is supplied with a logic ``1'' level signal specifying the online mode, the transmission function is disabled and no data is transmitted.

As a result, input data is not supplied to the center device CC from the terminal, and the terminal can perform its own processing.

Further, whether in the online or offline state, if the user wants to check the cumulative data of the transaction counter, he or she presses the inquiry key I.

As a result, reading is activated in the reading unit RD, and the following steps are performed.
In the same manner as described above, the contents of the transaction counter are printed out for each type.

As explained above, according to the present invention, by switching the switch between online mode and offline mode, the cumulative data up to that point can be automatically printed out, and complicated operations are not required when switching as in the conventional mode.

Although I did not explain this, when the mode is switched, except when printing an inquiry, the reading section reads and outputs the contents of all transaction counters, and then all transaction counters are cleared by other processing means. Then, there is an advantage that the cumulative data in each mode can be obtained immediately.

In addition, a display device is provided, and the reading unit notifies these display devices that the printing output of all transaction counters has been completed, outputs a message such as "Kakuninseyo" on the display device, and confirms the following input with an end key etc. By prohibiting the button until it is pressed, it is possible to reliably prevent forgetting to confirm when switching.
