PURPOSE:To ensure the contact between a prescribed part of a head and a sensor and to extract an output level of a voice signal stably by providing a projecting guide to a head rest in which the voice input sensor is imbedded. CONSTITUTION:When a head 1 reaches a head reset 2, the head 1 touches with a projecting guide 4 to guide the head 1 toward a sensor 3 fitted to the head rest 2 and a prescribed part of the head 1 is in contact with the sensor 3. Thus, when the head 1 is in contact with the head rest 2, the prescribed part of the head 1 and the sensor 3 are surely in contact with each other to offer the effect of outputting a stable voice signal. |
