Generic handheld symbology scanner with a modular optical sensor
First Claim
1. An apparatus for scanning a one or two-dimensional bar code symbol, comprising:
- a scanner housing having a scan head, said scan head including a receptacle disposed therein;
a scanning control unit disposed within said housing separate from said receptacle and electrically connected to a first connector provided in said receptacle; and
an optical module adapted to removeably engage said receptacle, said optical module comprising a second connector adapted to mate with said first connector upon engagement of said optical module with said receptacle, said optical module further comprising an optical sensor adapted to receive light reflected from said bar code symbol through an opening of said scan head and convert said light into data representative of said symbol, said data being thereby provided to said scanning control unit.

Abstract
A scanning apparatus comprises a scanner body portion having an internal receptacle within a scan head portion thereof. A scanning control unit is disposed within the body portion separate from the receptacle and has an electrical connection that extends through the body portion to the receptacle. A removable optical module is adapted to engage the receptacle and be connected electrically to the scanning control unit through the electrical connection. The module includes an optical sensor adapted to receive light reflected from the bar code symbology through an opening through the body portion and convert the light into data representative of the symbology. The data is thereby provided to the scanning control unit. The optical sensor may comprise either a one-dimensional charge-coupled device, a two-dimensional charge-coupled device, an articulated laser, or a light emitting diode.
