1. A laser scanning module, comprising:

  • a module housing having a light transmission aperture for the transmission of a laser scanning beam and collection of return laser light and optics mounted in said module housing for folding said laser scanning beam and collecting return laser light reflected or scattered from a scanned code structure;

    a PC board disposed in or on said module housing and having a configuration of elongated apertures of open-ended and/or closed geometry formed therein in a non-parallel manner and one or more electronic circuits formed thereon with at least one electronic circuit having a conductor formed adjacent said elongated apertures; and

    a laser scanning assembly disposed in said module housing and having a scanning subassembly including a mirror element and an electromagnetic coil structure with a set of electrically-conductive pins for scanning said laser scanning beam through said light transmission aperture and across a laser scanning field;

    a scanning assembly pivot mechanism disposed in said module housing for (i) rotatably mounting said laser scanning assembly, including said scanning subassembly and said electromagnetic coil structure, about an axis of rotation within said module housing and (ii) allowing said laser scanning assembly to be rotated to an angular position about said axis of rotation;

    wherein said set of electrically-conductive pins associated with said electromagnetic coil structure project through said configuration of elongated apertures formed in said PC board at locations along said elongated apertures determined by said angular position.
