ABSTRACT:
A portable instrument incorporates an electro-optical assembly for reading indicia during a reading mode, and for projecting a bit-mapped image during a display mode. A manually operable switch on the instrument is disposed for selecting one of the modes. The image is formed by pulsing a laser at selected times on selected scan lines.
