ABSTRACT:
A guide for mounting on an optical scanner, said guide including a guide framework provided with a laterally extending guide arm having a straight edge bearing surface which cooperates with a bearing surface on the scanner housing whereby the scanner can be moved in a parallel relationship with the straight edge to prevent lateral movement of the scanner or unintentional rotation of the scanner for superior scanning capability. The guide arm is preferably received within a passage or channel in the framework for reciprocal, lateral movement to adjust the guide arm and hence the bearing surface to be in proper alignment with the bearing surface on the scanner. Double sided adhesive tape provides secure attachment and detachment from the scanner without mutilation of the scanner.
