Patent ID: 8772659

Claim:
An electronic apparatus comprising: a key top; a lifting/lowering mechanism supporting the key top for free up-and-down motion between a raised position and a lowered position; a contact portion that effects switching in conjunction with the up-and-down action of the key top; a resilient member that, along with being capable of causing the key top to remain on standby in the raised position, can be resiliently deformed during the downward travel of the key top; a substrate that, along with supporting the lifting/lowering mechanism, has the resilient member disposed thereon, and a first sound dampening member arranged on the surface of the substrate where the lifting/lowering mechanism is provided, and abuttable by an edge of the key top when the key top is at the lowered position, wherein the first sound dampening member is formed from a resiliently deformable material and has an opening at a position corresponding to the key top, and the opening extends to a position outside of the key top in aplanar view so that a space under the key top and a space outside the key top communicate with each other when the key top is at the lowered position.
