Title:
発電入力装置および前記発電入力装置を使用した電子機器
Document Type and Number:
Japanese Patent JP5859763
Kind Code:
B2
Abstract:
First and second opposing ends are formed in a magnetic path forming member on which a power generation coil is wound. A rotating body has a permanent magnet, a first magnetization member and a second magnetization member. When an operating force does not act on an operating member, an end surface of the first magnetization member is opposed to the first opposing end via a gap and an end surface of the second magnetization member is opposed to the second opposing end via a gap. When the operating member is pressed, the rotating body rotates and when the force to the operating member is released, the operating member and the rotating body return. Since the rotating body and the magnetic path forming member do not come into contact with each other, the force required to operate the operating member is relatively weak and large electromotive force can be obtained.
