Title:
OPERATION INPUT DEVICE AND OPERATION INPUT DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/134558
Kind Code:
A1
Abstract:
Disclosed is an operation input device that receives force applied by an operator, which comprises a substrate (10) having an arrangement surface on which coils (21 to 24) are disposed in a circumferential direction of a circle formed by connecting points at an equal distance from a reference point, a key (30) disposed on a side of the substrate (10) from which the force is input, and return springs (51 to 54) that elastically support the key (30). The key (30) has an opposing surface that opposes the arrangement surface and an operation surface on which the force can act. When the opposing surface approaches the arrangement surface due to the force acting on the operation surface, the inductance of at least one of the coils (21 to 24) changes.
