A portable, stand-alone, desk-top, laser scanning workstation includes a laser scanning head mounted above a support base. Objects bearing bar code symbols to be scanned are passed underneath the head for overhead scanning, or are passed along one side of the head for sideward scanning. The symbols are oriented face-up towards the handler all during their passage through the workstation to facilitate sighting and registration of the symbol with the laser light beam generated by the head. The workstation is self-supporting, is fully portable, can process objects of different sizes, and grants access to objects from either side of the workstation. The workstation is connected to a microprocessor-based microcomputer which is mounted within a desk-top console, as well as to a variety of peripheral devices such as a printer, a keyboard, a communications port, audio-visual annunciators and a data display. The workstation, console and peripheral devices all constitute an intelligent laser-based data acquisition terminal for use in a variety of applications.

In a laser scanning system, a portable, stand-alone, desk-top, laser scanning workstation for reading bar code symbols on objects passing through the workstation, comprising: (a) a single housing having wall portions bounding an outlet port; (b) miniature light source means mounted within the housing, for generating a laser light beam; (c) miniature optic means mounted within the housing, for directing the laser light beam along a light path through the outlet port and towards a bar code symbol which is located in the vicinity of a reference plane that is located exteriorly of the housing; (d) miniature scanning means mounted in the light path and within the housing, for cyclically sweeping the laser light beam across the bar code symbol for reflection therefrom; (e) miniature sensor means mounted within the housing, for detecting the intensity of light reflected from the bar code symbol, and for generating an electrical signal indicative of the detected intensity of the reflected light; (f) miniature signal processing means mounted within the housing, for processing the electrical signal to generate therefrom a processed signal descriptive of the bar code symbol; (g) all of said miniature light source means, optic means, scanning means, sensor means, and signal processing means together with said housing constituting a light-weight, compact laser scanning head; (h) a base located exteriorly of the housing and mountable on a support surface; and (i) means for mounting the head on the base to constitute a laser scanning workstation which supports itself on the support surface and which is portable as a unit from one location to another, said head being mounted at a predetermined elevation above the base to permit the user to view the bar code symbol from above the same, and to position the bar code symbol in the light path of the laser light beam exteriorly of the outlet port during passage of the object through the workstation.
