    摘要: An optical unit of an optical scanning-type touch panel is constructed by providing a light emitting element for emitting infrared laser light, a collimation lens for changing the laser light from the light emitting element into parallel light, a light receiving element for receiving scanning light, a slit plate for limiting incident light on the light receiving element, a polygon mirror for angularly scanning the laser light from the light emitting element, an aperture mirror for limiting light projected onto the polygon mirror from the collimation lens by an aperture and for reflecting the reflected light from the polygon mirror toward the light receiving element, a light receiving lens for focusing the reflected light from the aperture mirror, and a motor for rotating the polygon mirror in a single optical unit main body as one unit.

    摘要: In order to measure a scanning light cut-off region, an output of a light receiving element and a threshold value set by an MPU are compared by a comparator and a region where the former is smaller than the latter is measured as the scanning light cut-off region. During one cycle of optical scanning, this threshold value is switched in a plurality of stages according to the scanning angle. By accurately measuring the scanning light cut-off region, the correct position and size of an indicator such as a finger or pen are calculated.

    摘要: Laser light emitted by a light emitting element is made parallel light by a collimation lens, passes through an aperture of an aperture mirror, and is then angularly scanned in a plane substantially parallel to a display screen by rotation of a polygon mirror and projected onto a recurrence reflection sheet. Then, after the reflected light from the recurrence reflection sheet is reflected by the polygon mirror and aperture mirror, the light is focused by a condenser lens to enter a light receiving element. The aperture mirror has an asymmetrical shape in the scanning direction and/or the vertical direction about the optical axis, according to a scanning surface opening width of the polygon mirror.
