Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register (hereinafter referred to as ECR) used in an in-line system in which a center computer and a plurality of electronic cash registers are combined.

Conventionally, in an inline system consisting of a center computer and multiple ECRs, when ECR settlement data is collected into the center computer, an electronic cash register performs settlement processing upon a settlement request from the center computer, and the data is transferred to a transmission buffer. and sent it to the center computer. Unfortunately, there is a problem in that data exchange takes time and data transmission takes time. Also, if there is a payment request, the registration operation will be stopped while the ECR is in the process of payment or data exchange.
There was a risk that the customer would be forced to wait until the payment process was completed.

An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional ECR, and to quickly respond to settlement requests from the center side. Moreover, it is an object of the present invention to provide an ECR that does not stop the registration operation even while responding to a payment request and does not impair service to customers.

In order to achieve the above object, the ECR of the present invention includes two storage sections, a first and a second storage section, and a switching circuit section for selecting these storage sections. By the operation of the unit, subsequent registration data is stored in the other storage unit, and data stored in one of the storage units is sent to the center computer.

The present invention will be described in detail below with reference to embodiments shown in the drawings.

FIG. 1 is a block diagram showing an outline of an inline system in which the ECR of the present invention is implemented. In the figure, there is a center computer CC and n ECRE1.

E2...En are coupled and connected to the center computer cc and each EC'RE1, E2-...-En
Data is exchanged between them.

FIG. 2 is a circuit block diagram showing the configuration of an ECH according to an embodiment of the present invention. The ECR shown here is employed as each ECREI, E2, . . . En of the system shown in FIG.

In Fig. 2, 1 indicates a keyboard for inputting registration data, etc., and 2 indicates a button for printing registration/payment data, etc.
Furthermore, it is a display section including an indicator light and the like that displays a data transmission preparation completion state. 4 according to the program stored in ROM5.

This is a central processing unit (CPU) that controls and executes ECR functions such as registration 9 inspection, settlement, and transmission. Further, 6 and 7 are memories M1 and M2 as storage units provided independently from each other for storing registration data and payment data. 8a and 8b are switching circuits, and these switching circuits 8a and 8b have built-in settlement flag storage areas and switching flag storage areas. The aforementioned CPU 4 still has a built-in registered END flag storage area. 9 is a transmission interface circuit for coupling with the center computer CC shown in FIG.

In the circuit shown in FIG. 2, the registered data is the switching circuit 8a, 8
6 stored in the memory determined by the switching flag b, that is, when the switching flag is '0'', the registered data is stored in the memory M1, and when the switching flag is '°1'', the registered data is stored in the memory M2. be remembered. Also, the switching circuit 8a
- The data stored in the memory determined by the switching flag in the settlement flag 11"' of 8b is sent to the center computer via the switching circuit Bb and the transmission interface 9. In other words, when the switching flag is °t1" The data stored in memory M1 is sent out, and the switching flag is set to u, OI.
The data stored in the memory M2 is configured to be sent out in the case of T. Therefore, when the switching flag is '0'', the registered data is stored in the memory M1 and the stored data in the memory M2 is sent out, and conversely, when the switching flag is '1'', the registered data is stored in the memo 11M2, and the data stored in the memory M2 is sent out. The data stored in M1 is now sent out.

Next, referring to the control flow shown in FIG. 5, FIG.
The operation of CH will be explained. In the figure, the CPU 4 at step ST (hereinafter abbreviated as ST) 11.

Determine whether it is a keyboard interrupt. If keyboard 1
If any key is operated, ST is determined as YES.
12, it is determined whether it is a payment key.

If the pressed key is the settlement key, that is, it is a settlement command from the ECR itself, the determination is YES and the process moves to 5T15.
At that point, the memory in which the registration data is stored (for example, the memory 1JM2 when the switching flag is "1") is processed for payment, and the payment data is printed out using the printer 2.Then, at 5T14, the payment W flag is set to 0. °1" and then convert the switching flag with 5T15 (for example, °°1").
"' to O"') shi.

In ST16, a display indicating completion of transmission preparation is performed.

Moji center computer CC makes a payment request to ECR. , the operation flow is 5T1 with 5Tii judgment NO.
Proceed to step 7 and make a determination for °°Settlement Settlement Request Interrupt Example': YES
Therefore, move to 5T1B and determine whether the settlement flag = 1. Already on the ECH side, for example, the above-mentioned 5T12 → 5T
13 → 5T14 → ...If the payment is completed as shown in 5T16, the payment flag becomes °'1"', so if the judgment is YES, the process moves to 5T19 and the memory specified by the switching flag (for example, the switching flag °' Note if 0”’! JM2)
The settlement data is transmitted to the center computer CC via the transmission interface 9.

If there is a request for payment from the center computer CC while the payment has not yet been made on the ECH side, the process moves to 5T20 based on the determination dNO at 5T1B, and a display indicating that there is a payment request is made.

From this display, the ECH operator knows that a payment request has been made by the center computer. Next, ST21
Then, it is determined whether the registration operation is in progress. If the mode setting key on the first side of the keyboard is set to registration mode, the judgment will be Y.
Becomes ES, moves to S'l'22, and registers E in CPUJ.
Determine if the ND flag is 1. If the registered END flag is ``''
As long as it is not 1", the judgment will be No and this step will remain until the registration END flag is set. This is because the registration JOB key is pressed during the registration operation and the payment operation will not start for a certain period of time.The registration END flag is ST3 [It is set in the flow below 1. In other words, when any of the registered JOB keys on the keyboard 1 is pressed at the stage where there is a settlement request interrupt, the operation flow is 5T110 judgment YES ST12 (7) judgment NO
, 5T30's determination of "Is there a payment request interrupt?" is YES, and then 5T51 is when the built-in 1 timer F is set in the CPU4.
Determine whether it is medium or not.

If the timer is not being set, the determination is No and the process starts at 5T32. And in s'r34, ``Is the timer count up?''
judge. Since the timer has not counted up yet when the timer starts counting, the judgment is No, and the operation flow returns to the start, ST11, ST12.5T50
When it reaches 5T5i, it is determined whether the 1 timer is being set or not.
Moving on to ES and Nashi5T36. ST36 is °1 registered JO
Then, if the registered JOB key is not pressed, the judgment is NO and the process moves to s'r34.

Determine whether the timer has counted up. Then, a new registered JOB key is pressed, and the operation continues for a period of 92 or more, and the timer continues counting.

Then, when the timer counts up, the determination at 5T34 is YES, and the registration END flag is set at 5T35.
1''. If the registered JOB key is pressed before the registered END flag is set to °°1'''i..., the judgment at 5T36 becomes YES, the timer is reset again at s'r32, and the timer is set at 5T33. Then, the timer starts counting again from 0. Then, at 5T34, the timer continues counting until the determination of "Is the timer count up" becomes YES. Next registration before count up
When the OB key is pressed, the timer is reset after the initial reset, and the same operation as described above is performed. When a certain period of time passes after the registered JOB key is pressed, the timer times up and the judgment of 5T34 becomes YES.
At T35, the registration END flag is set to °'1'.

Now, the explanation returns to ST22. Registered END flag =
If it is not 61", stay at this step, but if the registration E
ND flag is 9@1” and fisT22 judgment is YES
Then, the process moves to 5T23 and the settlement flags of the switching circuits 8a and 8b are set to '1#. Then, at 5T24, the switching flag is switched (for example, from "°1" to '0'), and at 5T25, the transmission preparation completion is displayed.Then, at 5T26, the memory specified by the switching flag (for example, if the switching flag is "0") Memo!JM2) is sent to the center computer CC via the transmission interface 9. and 5T
At step 27, payment processing and data printing is performed.

When the payment processing is completed, a clear command is sent from the center computer CC. Therefore, on the ECH side, the operation is STfl's "keyboard interrupt" judgment NO → 5T
Judgment No-, 5rsy of 17 “Other than payment request interruption”
``Is it clear command interrupt?'' judgment is YES and ST

Set the settlement flag 'k'011 with 5T41 and register END.
The flag is set to °°0'' and the timer is reset in ST42.Then, in ST43, the transmission preparation completion indicator is turned off, and in s'r44, a printout indicating that the payment process has been completed is printed.The ECR operator also knows the completion of payment by this printout. be able to.

In the above manner, the ECR is sent from the center computer CC.
When a payment request is received, if the memory that had previously stored the registered data is Ml, the registration data after receiving the payment request is stored in the memory M2, and the memory M
1 is sent to the center computer CC, and when the next payment request is made, the subsequent registration data is stored in the memory M1, and the data stored in the memory M2 is sent to the center computer. I am trying to send it to.
