Abstract
An optical data code reader employing a scanner of simplified compact construction, which is constituted by a light projection means including a light source and a converging lens and a reflected light sensor means including a reflected light capture lens and a photosensitive element. A laser diode serving as the light source and a photodiode serving as the photosensitive element are mounted side by side on a common substrate in the form of a single chip module. A converging ball lens of the light projection means and the capture lens of the reflected light sensor means are mounted on a common support member, which is connected to the substrate of the laser diode and photodiode in such a manner as to facilitate assembling of the respective components. The capture lens is arranged as a narrow band pass filter permitting passage of only light rays of wavelengths originating from the light source of the scanner.
