ABSTRACT:
A push button device for an electronic device includes an annular translucent member fixed to a body of the electronic device; a push button positioned in the annular translucent member to be capable of being depressed; a light emitter for illuminating the annular translucent member; a convex semi-cylindrical surface which is a portion of a complete cylindrical surface, and is positioned on a side of a space between the light emitter and the annular translucent member; and at least one photoreflective sheet adhered to the convex semi-cylindrical surface. An axis of the complete cylindrical surface extends in a direction substantially parallel to a direction along which the light emitter and the annular translucent member are aligned. A direction normal to a tangent plane to the convex semi-cylindrical surface extends toward the annular translucent member and the push button.
