Title:
INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/093095
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); a light-receiving element (5) connected to another end face of said core (2); and an erase-mode button (6). When pressure is applied at a given position within an input region consisting of the section of the surface of the top cladding layer (3) corresponding to the section where the grid-forming core (2) is, said position is detected via the resulting attenuation of the light received by the light-receiving element (5), yielding input information. If the erase-mode button (6) has been pressed, previously inputted information corresponding to a position within the input region where pressure is applied is identified as erasure information and erased.
