<p>A miniature scan module (12) which is adapted to be installed as part of a terminal or other apparatus for the reading of bar codes has an integrated assembly of a laser diode (58,60) and a photodetector (56) which is rotatably mounted for reciprocation about an axis (80) of rotation. The assembly is supported in whole or in part on and connected electrically to, a mounting board (14) by flexures (81,84) which extend between the integrated assembly and supports (89,90) on the board. The assembly has a body (28) with a wall (30) and a platform (32). The wall supports the laser and has a reflective surface which directs light (68) resulting from the scanning of the laser beam across the bar code to the detector. The assembly also carries printed circuits connected to the detector and the laser diode. Connections are made through the flexures to these printed circuits and to other circuits on the mounting board. <IMAGE></p> |
