Abstract:
A coordinate sensor of the present invention includes light emitting diodes (10) and line sensors (13) each including light receiving elements (13s), and further includes, between the light emitting diodes (10) and the light receiving elements (13s), wavelength selective reflection mirrors (11) for allowing light emitted from the light emitting diodes (10) to be selectively incident to the light receiving elements (13s).
