Abstract

An electronic device includes a diaphragm having a contact surface configured to contact a subject and a reflective medium on a surface of the diaphragm opposite the contact surface, the diaphragm being configured to elastically deform when pressed by the subject at the contact surface; a light-emitting diode; an aperture configured to narrow light emitted by the light-emitting diode; a photodetector having a light-receiving surface configured to receive light that passes through the aperture and is specularly reflected by the reflective medium; an output unit configured to output a signal based on light in an illuminated region formed on the light-receiving surface by the reflected light; and a housing enclosing the light-emitting diode, the aperture, and the photodetector, wherein the diaphragm is configured to form part of an exterior of the electronic device together with the housing, and wherein a boundary of the illuminated region, the boundary being defined by the light narrowed by the aperture and specularly reflected by the reflective medium, moves in accordance with displacement of the contact surface caused by elastic deformation of the diaphragm, thereby changing an area of the illuminated region on the light-receiving surface and changing an output of the output unit.
