[Problems to be Solved by the Invention] As mentioned above, in the conventional data communication system, business data is transmitted from a terminal device to a computer, and the computer determines whether or not it is the operating date for the relevant business. When this is not the operating day, the operation of sending business data from the terminal device to the computer every time it occurs is repeated, which places a load on both the terminal device and the computer, and increases communication costs.

The present invention has solved the above-mentioned problems, and its purpose is to provide a data communication system that reduces the burden on computers and terminal devices and reduces communication costs.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a computer that specifies an operation date for each business content and sends the data, and a computer that is connected to the computer via a line and sends the data. The present invention is characterized by comprising a terminal device that stores a stored operation date and can send the business data to the computer only when input business data corresponds to the stored operation date.

[0006]The above-mentioned computer can send the operation date data to the terminal device by providing a business operation date transmitter that can set and send operation date data for each business content within a certain period of time.

[0007] The terminal device further includes: a business operation date receiving unit that receives operation date data from the computer; and a business operation date storage unit that stores the operation date data received by the business operation date receiving unit. A business operation date confirmation unit that sends the data to the computer when the business data input by the operator matches the operation date of the operation date data in the business operation date storage unit, and notifies the computer that business processing is not possible when they do not match. With this, when business data is input, it can be determined whether or not to send the business data only within the terminal device.

[0008]

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

FIG. 1 is a block diagram showing an embodiment of the data communication system of the present invention. In the embodiment shown in FIG. 1, a computer network is configured by connecting a central host computer 10 and a terminal device 20 through a communication line 30.

[0010] The computer 10 includes a business operation date transmitting unit 1
1. The business operation date transmitting unit 11 can set operation date data for each business content within a certain period of time and can send this data.

The terminal device 20 has a business operation date receiving section 21, a business operation date storage section 22, and a business operation date confirmation section 23. In the figure, the business operation date storage unit 22 is stored in an external storage device, but if a storage device whose memory is not erased (for example, EP-ROM) is used, even if it is stored inside the terminal device 20. good. The business operation date receiving unit 21 receives operation date data from the computer 10. The business operation date storage unit 22 stores the operation date data received by the business operation date receiving unit 21. The business operation date confirmation unit 23 sends the data to the computer 10 when the business data input by an operator (not shown) matches the operation date of the operation date data in the business operation date storage unit, and sends the data to the computer 10 when they do not match. Notify the operator that business processing is not possible.

The operation of the embodiment configured as described above will be explained.

FIG. 2 shows a data layout diagram of the business operation date storage section 22 provided in the terminal device 20, in which business codes 41 and one year's worth of business operation days 42 are provided in correspondence. .

First, data on business operation days for each business code for one year is set in advance in the business operation date transmitter 11. Next, the business operation date transmitting unit 11 transmits the business operation date data to the terminal device 20. It is assumed that the business operation date transmitting unit 11 transmits the business operation date data to the terminal device 20 once a year and when the business operation date is changed.

[0015] The business operation date receiving section 21 of the terminal device 20 includes:
The business operation date data received from the computer 10 is stored in the business operation date storage section 22.

Next, the operation when the terminal user transmits business data from the terminal device 20 to the computer 10 will be explained. A terminal user inputs business data from a keyboard (not shown) of the terminal device 20. The input business data is passed to the business operation date confirmation section 23. The business operation date confirmation unit 23 retrieves the business operation date data from the business operation date storage unit 22 and checks whether the operation date of the business data input by the terminal user exists therein. If the business data input by the terminal user has a date of operation, the data can be processed by a computer, so the business operation date confirmation unit 23 transmits the business data input by the terminal user to the computer 10. On the other hand, if the operation date of the business data entered by the terminal user does not exist, the data cannot be processed by a computer, so the business operation date confirmation unit 23 responds with a reception refusal message to the terminal user stating that the operation date is not the input business operation date. do. This allows the operator to know that it is not a business operation day.

As a result, according to this embodiment, communication is not performed between the computer 10 and the terminal device 20 on days other than business operation days, so that the load on both the computer 10 and the terminal device 20 is reduced, and Communication costs can also be reduced.

[0018]

Effects of the Invention The present invention provides business operation date data to the terminal device when communicating between a computer and a terminal device at a remote location, and each time business data is input, the terminal device changes the business operation date data. This has the effect of reducing the load on computers and terminals, and reducing communication costs.
