Abstract
An absence reception information device for informing the user of a folding portable cellular phone about occurrence of a call during the user's absence is proposed. A folding portable cellular phone generally has a body, a cover section which is rotatably attached to the body, and an LCD (Liquid Crystal Display) for displaying necessary information. The LCD is usually provided on the inner side of the body or the cover section and can not be seen by the user when the cover section is closed. The absence reception information device comprises an LED (Light-Emitting Diode) which is placed on the folding portable cellular phone so as to be seen by the user when the cover section is closed, and an open/close detection circuit. The open/close detection circuit detects whether the cover section is opened or closed. The LED executes absence reception information display for informing the user about occurrence of a call during the user's absence, when the open/close detection circuit is detecting that the cover section is closed. The user can easily see the LED and check whether or not a call from a calling party occurred during the user's absence, even if the cover section is closed, that is, even if the folding portable cellular phone is folded up.
