INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/093287
Kind Code:
A1
Abstract:
This invention provides an input device whereby information such as inputted text can be erased. Said input device is provided with the following: a tetragonal sheet-shaped optical waveguide (W) comprising a grid-forming core (2) sandwiched between a tetragonal sheet-shaped bottom cladding layer (1) and top cladding layer (3); a light-emitting element (4) connected to one end face of the core (2) of the optical waveguide (W); and a light-receiving element (5) connected to another end face of said core (2). The section of the surface of the top cladding layer (3) corresponding to the section where the grid-forming core (2) is constitutes an input region. From pressure applied by a tip input section of an input body and a tip eraser section of an eraser body having different thicknesses, input information and erasure information are recognized from the difference in thickness. Previously inputted information corresponding to a position within the input region where pressure is applied by the tip eraser section of the eraser body is recognized as erasure information and erased.
