ABSTRACT:
An ultra-compact laser scanner comprising a self-contained housing including a handle portion configured to be readily held within the hand of a person and a short length body portion projecting outward from the handle portion. A subassembly including a laser tube and associated power supply is mounted on a circuit board within the handle and can be readily removed therefrom. A signal processing subassembly is located within the body portion above the handle. A motor and optic system subassembly is also mounted within the body portion and is arranged to direct a beam of laser light from the laser tube through an arc out through a window in the front of the body portion of the housing to sweep across a bar code symbol at which the device is aimed. A beam width adjusting/beam blocking moveable curtain is mounted over the window. Light reflecting off the bar code enters back into the housing through the window, passes through a compact optic path to a photodetector and associated signal processing components so that the bar code scanned is decoded. The device includes a trigger for effecting the scanning operation. The decoded signals are provided via a cable to associated peripheral equipment, such as electronic cash registers, computers, etc.
