Abstract
An information processor including a keyboard, a main body and a display device. The keyboard is provided with plural infrared-ray emission elements which are located at different positions so as to face in different directions, and an identifying code setting switch for setting the identification code of the keyboard into an infrared-ray signal transmitted from each infrared-ray emission element. The main body includes plural infrared-ray receiving elements which are located at different positions so as to face in different directions, an identifying code setting switch for setting the identification code of the keyboard, and a keyboard controller for judging whether the same identification code as set by the identification code setting switch is contained in the infrared-ray signal which is received by any one of the infrared-ray receiving elements.
