BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device having a function of notifying a host computer or the like connected via a communication line of a data processing result.

[0002]

2. Description of the Related Art Some data processing devices for executing data processing by timely executing various preset business programs have a function of notifying a host computer or the like connected via a communication line of a data processing result. There is.

This notification function is provided in, for example, a store processor of a POS (Point of Sale Information Management) system. The store processor executes sales price change work, various master file update work, etc. to the POS terminal for product sales data registration connected by an inline line, and notifies the host computer of the data processing result each time. .

By providing such a notification function,
This is convenient because the data processing result in the data processing device main body can be monitored by an external device such as a host computer.

By the way, in the data processing apparatus of this type, conventionally, every time a processing result of each activated business program occurs, information indicating the processing result in real time is sent to the communication line regardless of whether the processing is normally completed or abnormally completed. Through the host computer.

[0006]

As described above, conventionally, since the information indicating the processing result is transmitted in real time, line connection and disconnection are frequently performed. For this reason, when a dedicated line such as ISDN (Integrated Services Digital Network) is used as a communication line, the line usage fee becomes high and the cost becomes high.

Therefore, the present invention intends to provide a data processing device capable of reducing the cost by reducing the number of times of notifying the data processing result without interfering with the work of monitoring the data processing result performed by an external device. It is a thing.

[0008]

The present invention relates to a business program connected to an external device through a communication line and for performing various data processing, and a communication program for notifying the external device of the data processing result. And a data processing result stored in the storage unit, the result information storing unit sequentially storing information indicating the data processing result every time the data processing is performed by executing the business program. Result investigation means for examining the information at a certain time interval to check whether there is information indicating abnormal termination, counting means for counting the number of investigations by the result examination means, and the count value by the counting means has reached a predetermined value. At this time and when the presence of the information indicating the abnormal termination is confirmed by the result investigation means, the communication program is executed and the data stored by the storage means is executed. The information indicating the processing result via the communication line is obtained and a processing result notification means for transmitting to an external device.

[0009]

According to the present invention having such a configuration, every time data processing is performed by executing the business program, information indicating the data processing result is sequentially stored by the result information storage means. Further, the information stored by the result information storage means is examined at regular time intervals. Then, if the presence of the information indicating the abnormal end is confirmed by this investigation, the information stored by the result information storage means is transmitted to the external device through the communication line.

On the other hand, if the existence of the information indicating the abnormal termination is not confirmed, the information stored in the result information storage means is examined again after a lapse of a certain time. Each time the information stored in the result information storage means is investigated, the number of investigations is counted by the counting means. When the counted value reaches a predetermined value, the information stored in the result information storage means is communicated. It is transmitted to the external device through the line.
