Abstract
A bar code reader for reading a bar code by emitting a laser beam from a laser diode toward the bar code and receiving the subsequently reflected light on a photosensor, in which the photosensor is disposed along an irradiating direction of the laser beam emitted from the laser diode, thereby achieving the most effective arrangement of the laser diode and the photosensor occupying less area.
