Embodiment Construction

[0038] See attached picture below, figure 1The reference number 10 in represents a light source, which is preferably a semiconductor solid-state laser packaged in a shell, the shell has a plurality of pins 12 protruding from the bottom wall of the shell, and the laser is suitable for passing through the shell when it is energized. A through hole in the upper wall emits a laser beam, preferably a visible laser beam. The housing 12 is inserted in the direction of arrow A into a cylindrical hole 14 in a support or frame 16 having a plurality of mounting posts 18 inserted into and extending through Image 6 Corresponding mounting holes are shown for a substantially planar base plate 20 , which is preferably an underlying printed circuit board (PCB) supported by frame 16 . Frame 16 supports laser 10 and all other elements of a scanning module or assembly, as described below.

[0039] As shown in Figure 7, the bottom wall of the shell rests on the upper surface of the printed circ...

Abstract

A non-retroreflective compact scan module in an electro-optical reader includes a laser light source, a photosensor and an electromagnetic coil mounted at one surface of a printed circuit board. The laser emits a laser beam perpendicular to the board, and is redirected to an oscillatable scan mirror which is magnetically centered to a rest position when the coil is de-energized. Electrical circuitry is mounted at an opposite surface of the board.

Description

technical field [0001] The present invention relates generally to electro-optic readers or scanners, such as bar code symbol readers, and more particularly to scanning modules for use where particularly compact readers are desired. Background technique [0002] Electro-optical readers, such as barcode symbol readers, are now very popular. Generally speaking, a barcode symbol consists of one or more rows of light and dark areas, generally in the form of rectangles. The width of the dark areas (ie, bars) and / or the width of the light areas (ie, spaces) between bars represent the encoded signal to be read. [0003] A bar code symbol reader illuminates the symbol and detects the light reflected or scattered from the bar code fields to detect the width and spacing of each coded field and obtain the coded information. Barcode reading data entry systems improve the efficiency and accuracy of data entry in a variety of applications. This type of system is convenient for data entr...
