Abstract: A method and apparatus for mounting a compact optical scanner utilizes a one or two-piece mounting bracket to secure the scanner. A bevelled surface on the inside of the bracket cooperated with a conversely bevelled surface on the scanner to prevent removal of the scanner through the top surface of the bracket. Flexible extensions support the scanner and flex out of the way to allow insertion and removal of the scanner.

Abstract: A soft compliant seal is attached to either an anchored or a loose reinforcement ring to provide a non-hermetic seal against liquids or particulates in order to maintain a space between two windows substantially free of all foreign matter.

Abstract: A mounting arrangement vertically mounts a scanner of the type which projects a laser light beam in a scan pattern to find a label on a package and read symbols thereon. The scanner has a housing, a window positioned on a first side of the scanner housing, power and communication cables emerging from a lateral side of the housing, and an optical system within the housing to project the beam through the window. The mounting arrangement includes a support plate for engaging a second side of the scanner housing opposite the first side. The support plate includes means for securing the plate to a horizontal surface. The mounting arrangement further includes a back cover for covering the side of the support plate on the side thereof opposite the scanner. Finally, the mounting arrangement includes a cable cover, securable to the support plate and to the back cover, for covering the cables emerging from the lateral side of the housing.

Abstract: A housing construction for a POS type bar code scanner with multiple apparent source scan geometry includes only two main housing components. Each a casting to which one or a number of routing mirrors are bonded so as to precisely locate the plane of each mirror. The routing mirrors are bonded to the castings preferably on spherical ball type locaters integral with the castings, and their positions are non-adjustable. Other mirrors and collection optics are also retained on the lower and the upper casting. For precisely locating the two castings with respect to each other upon assembly, the castings have three-point contact, coupled with casting bores and removable fasteners with shoulders of precise diameter, so that the relative casting positions are accurately located as to both tilt and lateral shifting. The spherical ball locating devices for the mirrors are positioned, on each of the two castings, with reference to the precision-located connection bores and contact points on that housing.
