Abstract

PURPOSE:To decrease the danger of a misoperation of a user by constituting the system so that as for a keyboard input in a non-display state, only a migration to a display state of a display device is executed, and it does not become an input to an application program. CONSTITUTION:The system is provided with a keyboard input device C, a display device D, an arithmetic processor A, and a main storage device B, and when the display device D is in a display state, a keyboard input is read out by an operating system, and transmitted to an application program. When the display device D is in a non-display state, the keyboard input is read out by the operating system and switches the display device D to a display state. Also, the input in this case is rejected in the inside of the operating system, and not delivered to the application program. In such a way, the system which scarcely causes a misoperation can be obtained.

Description

【発明の詳細な説明】 ［産業上の利用分野］ 本発明はコンピュータシステムに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to computer systems.

ことを目的とするものである。Therefore, in the present invention, in response to keyboard input in the non-display state, only the display device is shifted to the display state, and
The purpose of this system is to provide users with an easy-to-use computer system with less risk of erroneous operation by creating a system that does not provide input to application programs.

Arithmetic processing unit A processes information based on information in main memory B and input from keyboard C, and outputs the results to a display device. Further, the processing unit A switches the display device to a non-display state as necessary.
