<p><P>PROBLEM TO BE SOLVED: To provide a push-button apparatus capable of translating a button part to its pushing direction while keeping an attitude of the operating surface of the button part when pushing the button part connected to a key base through a hinge part. <P>SOLUTION: A key sheet 11 having a button part 13 is disposed on a supporting member 21 and is supported by it. A hinge part 12 is provided on a key base 11 having elasticity, and a notch 14 wider than the hinge part 12a is provided in the vicinity of the hinge part 12a on the key base 11. In the supporting member 21, a level difference 22 is formed parallel to the notch 14 on the upper surface of the supporting member 21 on the side closer to the hinge part 12a than to the notch 14 of the key base 11. Supporting parts 12b, 12c formed by a slit 15 produced in the key base 11 by pushing the button part 13 and the notch 14 and the hinge part 12a are elastically deformed, and when a bent part produced by the elastic deformation arrives at the bottom of the level difference 22 by bending by the level difference 22, any further bending is regulated. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
