摘要

PROBLEM TO BE SOLVED: To provide a device for notifying a user of an incoming call while a cellular phone is kept at a dark place such as in the bag.;SOLUTION: From sounds generated when a call is incoming to a cellular phone 1 or from vibration sounds generated in manners mode, a sound sensor 3 in tight contact with the cellular phone 1 of a call incoming signal transmitter 2 detects call incoming to the cellular phone 1. A light sensor 4 distinguishes a preservation situation of the cellular phone 1 by lightness based on a signal transmitted from the sound sensor 3 and only when the cellular phone 1 is kept at a dark place, the light sensor 4 sends a call incoming signal to a signal generating circuit 6. The call incoming signal causes a call incoming display 14 of a call incoming signal receiver 9 to display call incoming. Even when the cellular phone 1 is in a normal mode or in the manners mode, call incoming is displayed only when a preservation place is in the environment such as in the bag.;COPYRIGHT: (C)2009,JPO&INPIT
