<p>A support assembly (150) for a metal detection device (10) is disclosed. The detection device (10) includes a housing (12) with a central orifice (30), an induction member (82) surrounding the orifice (30) for generating an output voltage when a metal object is passed nearby, and a mechanism which includes pulse emitting (86) and pulse receiving (88) members for selectively sensing an object passing through the orifice (30). The support assembly (150) includes a base member (152) having front (154), rear (155) and opposed side (156, 158) portions sized and shaped for positioning beneath the housing (12). The base member (152) has a central aperture (160) adapted for substantial alignment with the housing orifice (30) when the base member (152) is positioned beneath the housing (12). A mechanism (162, 164) secures the base member (152) to the housing (12), and a plurality of mounting posts (166) are disposed along the base member front (154), rear (155) and side (156, 158) portions for positioning a metal detection device induction member (82) about the central aperture (160). A mounting mechanism (170, 172, 174, 176) is provided for the pulse emitting (86) and pulse-receiving (88) members on opposite sides (156, 158) of the central aperture (160). Finally, a plurality of pulse regulating elements (180) are provided for eliminating ambient light interference and cross-pulse sensing.</p> |
