JPH0511966A - Display picture controller - Google Patents

Abstract

PURPOSE:To facilitate operations by grasping the continuity relation of data on a display screen when a picture is moved. CONSTITUTION:For a display picture controller 1, data received by a communication control part 1 are edited by a data edition part 1b and stored in an edition buffer. A keyboard 3 and a display 2 are connected to a display execution part 1c for displaying the edited data on the screen and when a forward key is operated from the keyboard 3, a display start position is moved for the half of the screen. Then, the data for one picture are displayed from the position and simultaneously the head (the intermediate line of the screen) of the newly displayed data is reversed. Therefore, the data can be distinguished from the data remaining in the preceding picture.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen control device, and more particularly to a screen control device for controlling a display screen on a display.

[0002]

2. Description of the Related Art In a conventional display screen control device, when a forward key is pressed from a keyboard, a pointer designating display head data is shifted by one screen and display is started at that position.

[0003]

In the above-described conventional display screen control device, scrolling is possible on a screen-by-screen basis, and when scrolling, the data on the previous screen becomes invisible, so that the connection between the front and back is difficult to understand. There is a drawback.

[0004]

A display screen control apparatus according to the present invention comprises a data editing unit for editing input data and storing it in an edit buffer, and a display execution unit for displaying the edited data on a screen of a display. , A keyboard for changing and designating the display of the screen by operation input, and when the forward key is input from the keyboard, the display start position of the screen is moved by a half screen and data for one screen is displayed from that position. To do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.

The display screen control device 1 of the present embodiment includes a data editing unit 1b that edits data received by the communication control unit 1a and stores it in an edit buffer, and a display execution unit 1c that displays the edited data on the screen. When the keyboard 3 and the display 2 are connected, and the forward key is operated from the keyboard 3, the display start position is moved by half a screen, and one screen of data is displayed from that position, and at the same time, the newly displayed data is displayed. By reversing the beginning (the middle line of the screen), it distinguishes from the data remaining from the previous screen.

FIG. 2 is a diagram for explaining the operation of the present embodiment, in which the data received via the communication control unit 1a is first edited and displayed in the edit buffer by the data editing unit 1b. A pointer is set at the beginning of the edit buffer as a display start point for one screen. The display execution unit 1c displays the data for one screen from the position where the pointer is set on the display 2 as display data as shown in FIG. Next, when the forward key is pressed from the keyboard 3, the pointer moves by half a screen from the current position, and one screen of data is displayed on the display 2 from the moved position. Also, at this time, at the beginning of the newly displayed data,
That is, the middle row of the screen is reversed. The display contents at this time are shown in FIG. After that, the same operation is performed by pressing the forward key.

In this embodiment, the embodiment is limited to the line data, but the data display from the file of the auxiliary storage device can be similarly carried out.

[0009]

As described above, according to the present invention, when the forward key is pressed by operating the keyboard, the pointer indicating the display start point is moved by half a screen, and data for one screen is displayed from that position. By displaying the latter half data and the continuation data of the previous screen on the display as data,
There is an effect that the connection before and after the data on the display screen can be grasped and the operation becomes easy.
