Abstract

PURPOSE:To handle many kinds of fixed-form information without degrading the use efficiency of a line, by providing a storage device where plural format data are held in the terminal side to make the manual intervention on the terminal side unnecessary. CONSTITUTION:A format designating code ID112 of a business form and variable data 113 are transmitted from a central computer 100 and are received in a receiving buffer 106. A data control part 102 analyzes this data to transfer variable data 113 to a buffer 107 and reads out format data (for example, 111) corresponding to the format ID112 from a storage device 103 and transfers it to a buffer 108. Variable data in the buffer 107 and format data in the buffer 108 are edited together and are transferred to an output buffer. Edited data in the buffer 109 is outputted to a printer 104 or a display device 105.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an output method to a terminal system connected to a central computer via a communication line, and in particular outputs a plurality of fixed forms in various types and in large quantities. This invention relates to a terminal output method suitable for such cases.

[Prior art]

Conventional terminal systems that output a large amount of forms generally use pre-printed paper for the fixed part of the form, so when using different types of forms, the paper must be manually needed to be set. In order to solve this trouble, there is a method that sends form data of forms from a central computer to a terminal system, but this method uses 2 to 3 K bytes of information (fixed part printing information) as form data of forms as actual data. This had the disadvantage of inefficient use of the line, as it had to be sent to another source. Especially when handling image signals in the future, the size of the fixed part of the form will be several tens of thousands.
It is expected that the number of bytes will increase, and the efficiency of line usage will further decline.

[Purpose of the invention]

An object of the present invention is to provide a terminal output method that does not require manual intervention on the terminal side and can handle multiple types of fixed information without reducing line usage efficiency.

[Summary of the invention]

The main point of the present invention is that a storage device that holds a plurality of format data is provided on the terminal side, and when outputting forms, the central computer adds only a format designation code (format ID) to the actual data and The terminal side reads the format data corresponding to the sent format ID from the storage device and outputs the desired forms.

[Embodiments of the invention]

FIG. 1 is a block diagram of an embodiment of the present invention.

In the figure, a central computer 100 is connected to a terminal control device 101 through a communication line 120. The terminal control device 101 includes a storage device 103 such as a floppy device, and a printing device 1.
04 and a display device 105 are connected to form one terminal system as a whole. Various format data are stored in the storage device 108 as 111, 111', and 111. The terminal control device 101 includes a data control unit 10
2, reception buffer 106, buffer for town change data (actual data) xo7. It is composed of a format data buffer 108, an output buffer 109, and a transmission buffer 110. Among these, the data control unit 1o2J classifies the format ID given from the central computer 100, selects necessary format data from the storage device 108, and stores the format data in the buffers 107, 108.
, 109 to automatically create forms, or to request the central computer 100 to transfer unregistered format data using the buffer 110.

Now, the transmission data from the central computer 100 includes the form ID 112 of the form to be output and the town change data 118, and is once sent to the reception buffer 10 of the terminal control device 101.
Received on 6th. The data control unit 102 analyzes the data received in the reception buffer 106 and stores the town change data 11.
8 is transferred to the buffer 107. On the other hand, Form ID 112
, the format data (for example, 111) corresponding to the format ID 112 is read from the storage device 108 and transferred to the buffer 108. This format data corresponds to the fixed part of the Kuma slip. The variable data in buffer 107 and the format data in buffer 108 are edited together and transferred to output buffer 109. Figure 2 shows the buffer 107
, 108 before editing and the content after editing of Barafu 1090. The edited data in the buffer IM is then sent to the printing device 104 or the display device 105.
is output to.

Next, a case will be described in which the format data corresponding to the format ID 112 sent from the central computer 100 is not stored in the storage device 10B.

At least one storage device 108 is provided for the terminal system f1t101K, or at least one storage device 108 is provided for the printing device 104. However, due to physical capacity limitations, there may be cases where the format data corresponding to the format ID indicated by 112 in the transmitted data is not stored in the storage device 108. Whether format data corresponding to a certain format ID exists in the storage device 108 can be easily determined by managing the format ■D name corresponding to the format data stored in the storage device 108 in the data control unit 102. You can know.

If there is no format data corresponding to the format ID 112 in the transmission data in the storage device 108, the data control unit 102 temporarily stores the format ID 112 in the transmission buffer 110, and also stores the format ID 112 in the old terminal control device 1. The same address is set in the transmission buffer 110. Thereafter, the data control unit 102 transmits the contents of the transmission buffer 110 to the central computer 100 as an unused device format ID 114 and a device address 115. calculator 10
0 sends format data corresponding to format ID 11+ to the terminal control device 101 specified by the device address 115. The data control unit 102 of the terminal 7fflJ control device 101 stores the received format data in the buffer 1.
08, the variable data previously received and stored in the buffer 107 are collected, and outputted to the printing device 104 or display device 105 via the output buffer 109. By doing so, it is possible to cope with the limitation of the physical capacity of the storage device 108. Note that if there is an unused area remaining in the storage device 108, the format data sent from the central computer 100 is stored in the storage device xo as analytical data.
It could also be stored in a.

〔Effect of the invention〕

It is clear from the above explanation that, according to the present invention, it is necessary to manually set the paper, etc. Since it is only necessary to add D to the change data and send it to the terminal side, the above-mentioned line usage efficiency is achieved.
