摘要： An original document size detection device of the present invention is characterized by comprising a document reading table, a light source which irradiates an original document placed on the document reading table, a cover body which covers the original document, a light detection unit which detects a reflected light that a light from the light source is reflected by the original document and an external light that enters the surface of the document reading table when the cover body is lifted, a masking unit which masks an output signal based on the external light in the output signal of the light detection unit based on the reflected light and the external light, and a determination unit which determines a size of the original document in a main scanning direction based on the output signal of the light detection unit that is masked by the masking unit.

摘要： An optical switch is provided. The optical switch includes: a first distributed-coupling type optical coupler having a first optical waveguide and a second optical waveguide arranged in parallel with each other that outputs an input light inputted to an input end of the first optical waveguide from an output end of either the first optical waveguide or the second optical waveguide as output light; a first electrode that applies an electric field corresponding to the first input voltage to the first optical waveguide and the second optical waveguide and controls whether the input light inputted to the first optical coupler is outputted as the output light based on the first input voltage; and a phase modulation reducing section that reduces the phase change of the output light in accordance with the change of the electric field applied to the first optical waveguide and the second optical waveguide.
