PORTABLE TELEPHONE SET
Document Type and Number:
Japanese Patent JP3791134
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To temporarily release a misoperation prevention mode by a simple operation.
SOLUTION: When a touch sensor 7 is turned on by grasping a grip part of a telephone set main body by a user, the misoperation prevention mode is released for specified time on condition that any one key of a key operation part 2 is operated by a control circuit 8. Therefore, the misoperation prevention mode is returned to a normal mode without inputting a releasing code by key operation of the key operation part 2, the hasty key operation of a releasing mode is unnecessitated in the case that normal operation like response to an incoming call or emergency call, etc., is performed even in the misoperation prevention mode, the operation becomes easy, the mode is automatically returned to the misoperation prevention mode after the specified period and a misoperation prevention function is effectively used. Since the misoperation prevention mode is released on condition that any one key of the key operation part 2 is operated even when the touch sensor 7 is turned on, the misoperation prevention mode is not unnecessarily released when the touch sensor 7 is improvidently activated or failed by short-circuit.
