Title:
LIGHT-GUIDING SHEET AND MOVABLE CONTACT BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/011259
Kind Code:
A1
Abstract:
A light-guiding sheet has a film-shaped light transmissive base material, a plurality of light-emitting portions formed on the base material, and a light transmissive light-guiding layer covering the plurality of light-emitting portions. By this configuration, light enters the light emitting portions from the base material and the light-guiding layer, thereby increasing the amount of light scattered and reflected by the light-emitting portions. Therefore, a movable contact body using the light-guiding sheet enables bright illumination to thereby enable easy-to-see and easy operation.
