Provided is an optical detecting device, wherein a photodiode is provided on a first surface of a substrate, a planar output electrode for outputting electrical signals corresponding to a quantity of light received by the photodiode is provided on a second surface of the substrate opposite to the first surface, a cutout portion is provided in a third surface of the substrate such that the cutout portion is in contact with the output electrode provided on the second surface, said third surface being different from the first surface and the second surface, and an electrode connected to the output electrode is provided on the inner surface of the cutout portion.

Optical detection device, optical device, optical information reading device, and light source fixing method

A bar code scanner module is disclosed that may include a chassis housing an optical transmission system therein, the optical transmission system including a laser diode and a motor; a first circuit board coupled to the motor; and a second circuit board disposed within the chassis and in communication with the first circuit board. The module may further include a third circuit board disposed in proximity to the chassis and in communication with at least one of the first circuit board and the second circuit board.

Compact bar code scanner assembly

An optical aberration is intentionally introduced into the optical system which produces the scanning beam of an optical code scanner, in order to produce a scanning beam which has plural focal points or waists at different distances from the scanner. The operating range of the scanner can thereby be increased by taking advantage of different beam waist locations when the optical code is at different distances from the scanner. In accordance with an embodiment of the invention, coma is intentionally introduced to an optical system providing a light beam for an optical code scanner. This provides a scanning beam with plural beam waists at different distances from the scanner. This may be accomplished by orienting the light source and focusing optical system so that their optical axes intersect or by introducing an optical member, such as a prism, between the original light source and the focusing optical system.
