Provided is an electronic apparatus including a supporting member that supports an electronic pen including a terminal when the electronic pen is inserted into the apparatus, an electrode that is movably supported, and a movement mechanism that moves the electrode to a first position where the electrode comes into contact with the terminal by a force received from the electronic pen, when the electronic pen is inserted into the apparatus.

Electronic apparatus for communication between electronic pen and external device

An image reading apparatus includes: a light source that irradiates light; a switching unit that switches a direction of the light irradiated by the light source to one of a plurality of predetermined directions; a light guiding unit that guides the light whose direction is switched by the switching unit and that travels in one of the plurality of directions to a position predetermined for each of the directions; and a light sensor that, in a case where an object is in the predetermined position, measures light reflect by the object out of the light guided to the position by the light guiding unit.

Image reading apparatus

The electronic writing instrument is provided with: a writing unit that writes down on a medium where a code indicating identity information and location information of the medium is formed; an emitting unit that emits light to the medium; a photoelectric conversion unit that includes photoelectric conversion element receiving a reflected light from the medium by the light emitted by the emitting unit and outputting an electronic signal after converting the reflected light by photoelectric conversion; a receiving unit that receives a user operation; and a condition changing unit that changes at least any one of an emitting condition of the emitting unit to the medium and an output condition of the photoelectric conversion unit when the receiving unit receives an operation.

Electronic writing instrument, computer system, electronic writing method and computer readable medium

A reading device comprises: an irradiating unit that irradiates light onto a medium; an image forming unit that forms an image from irradiated light reflected from the medium; and an adjusting unit that causes an optical axis of irradiated light to be adjusted, under influence of weight of the irradiating unit, with respect to an optical axis of reflected light that occurs when the image forming unit forms an image of the reflected light.

Image reading device

The present invention uses a single substrate to provide a small-size optical waveguide element that requires no optical axis adjustments, can be driven at a low voltage, is excellent in light utilization efficiency, and can rapidly two-dimensionally deflect a light beam. A right-triangle upper electrode and a rectangular transparent upper electrode are formed on top of a thin-film optical waveguide formed on a conductive substrate to serve as a lower electrode, and an emission right-angled prism is secured on top of the transparent upper electrode. A voltage is applied between the upper electrode and the conductive substrate, and between the transparent upper electrode and the conductive substrate. A horizontal deflection is performed upon application of a voltage to the upper electrode and a vertical deflection is performed upon application of a voltage to the transparent upper electrode.

Optical deflection element

The invention intends to provides an optical waveguide device having a structure that satisfies the low drive voltage characteristic and the low propagation loss characteristic at the same time. The optical waveguide device contains a conductive or semiconductive lower electrode, an epitaxial or single orientational buffer layer provided on the lower electrode, an epitaxial or single orientational optical waveguide provided on the buffer layer, and an upper electrode of a conductive thin film or a semiconductive thin film, provided on the optical waveguide. The optical waveguide device is able to modulate, switch, or deflect incident light beams guided into the optical waveguide by applying a voltage between the upper electrode and the lower electrode.
