2. Description of the Related Art In recent years, graphical user interface technology has been improved, and even a beginner can use advanced application software.

However, in order to realize an easy-to-use user interface possessed by advanced application software, a software developer must design a complicated program, the burden on the software developer increases, and the development efficiency increases. Is declining. That is, although the original purpose of application software development is data processing, a great deal of effort must be spent on developing a user interface for inputting the data. In general, application software having a complicated user interface is poor in portability. This is because the application software has a program configuration in which a data input unit forming a user interface and a data processing unit processing input data are mixed.

[0004] As a solution to such a problem, a so-called "UIMS (user interface management system)" has been devised. This technology manages a user interface separately from data processing, and can have an application structure in which a data input unit and a data processing unit are separated. Therefore, the developer of the application software can design and develop the data processing unit independently of the data input unit. Further, in the application software developed using the UIMS technology, the change of the data input unit does not reach the data processing unit. As a result, it can be said that UIMS is a technology that can improve development efficiency and maintenance efficiency.

The above operation shown in FIG. 16 has been described for one data input / output terminal, the host information processing device, and the processing of key input information. However, as shown in FIG. The same applies to the processing with the processing device. That is, the host information processing apparatus manages a plurality of connected data input / output terminals for each terminal, and performs the processing shown in FIG. 16 for each input / output terminal.

Although the end of the processing is not described in FIG. 16, if there is a key input for instructing the end of the processing, the application is ended.

[0034]

In the prior art, as described above, screen display information depending on screen specifications such as the screen size and resolution of the data input / output terminal is generated on the host information processing apparatus (50) side. Was. Therefore, when a plurality of data input / output terminals having different specifications are employed, a problem may occur that a normal input screen is not displayed. That is, for example, when screen display information assuming a large screen size is generated on the host side, it cannot be displayed on a data input / output terminal having a small screen size (see FIG. 17). When the host information processing apparatus (50) generates screen display information on the assumption that a character string that can be displayed in one line is “32”, for example, the character string that can be displayed in one line is “ When the data input / output terminal of "24" is connected, the character string constituting the input screen is folded in the middle of the line, and there is a problem that a normal input screen cannot be displayed (FIG. 18).
reference).

Further, communication between the data input / output terminal and the host information processing device occurs every time a key is input from the user, and the connection is kept in effect during data input.

Therefore, there is also a problem that the communication load and the communication cost increase.

Further, the screen definition information stored in the screen definition section (51) has absolute display coordinates indicating the arrangement of parts such as fields constituting the input screen, and data of different screen sizes. When the input / output terminal is connected to the host information processing device, if the input screen is displayed in an abnormal state or the input screen looks normal, a small screen is displayed at the upper left of the screen. There was also an inconvenience of composing a bad input screen (FIG. 19).

According to the present invention, in view of the above-mentioned problems of the prior art, the screen definition in the host information processing apparatus is independent of the data input / output terminal, and an input screen suitable for each data input / output terminal can be constructed. It is another object of the present invention to reduce the communication load and communication cost between the host information processing device and the data input / output terminal.

[0039]

In order to achieve the above object, in a data input / output terminal device according to the present invention, screen definition information, which is information for constituting an input screen, is collectively read from an external device. A screen creating unit for creating an input screen according to the screen definition information, and a data input unit for inputting data from the input screen.

Further, it is determined whether or not the data input from the data input unit is a data transfer signal, and when it is determined that the data is a data transfer signal, a series of data input from the data input unit is converted to a predetermined external data. The apparatus further includes a data transfer unit that transfers the data to the device.
