Abstract

A scanning system (10) for reading bar code symbols including a portable hand-held scanning device (12) is provided. The portable hand-held scanning device (12) generates electrical signals descriptive of the bar code symbols and includes a manually actuatable trigger switch (26) for initiating reading of the bar code symbols each time the manually actuatable trigger switch (26) is actuated by the user when the portable hand-held scanning device (12) is supported by the user. The scanning system (10) further includes a fixture (14) for receiving and supporting the portable hand-held scanning device (12). The fixture includes a head portion (42) and a base portion (40). The hand-held scanning device (12) is supported by the head portion (42) a predetermined distance above the base portion (40) to allow objects bearing the bar code symbols to pass between the head portion (42) and the base portion (40). The fixture (14) further includes structure (64, 66, 70) for sensing the presence of an object between the head portion (42) and the base portion (40) and for automatically initiating reading by the portable hand-held scanning device (12) of the bar code symbols each time the sensing …
