Abstract
Abstract An inspection system is provided to simultaneously X-ray inspect hand carried articles and provide metal detection of the person of the carrier. These different inspections are independent, and may be carried out separately from one another. The X-ray inspection involves the insertion of a hand carried item into a chamber, and guiding it along the X-ray inspection station by holding a handle outside of the detector. Metal detection of the person may be accomplished independently by walking through a metal detector arch.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
131 words
Apparatus for inspecting an article comprising a longitudinally extending cabinet having top and bottom walls, oppositely disposed side walls, and oppositely disposed end walls; a longitudinally extending slot-like opening in said cabinet adjacent a corresponding edge of said top wall and a side wall; an entrance opening at one portion of said cabinet and an exit opening at another portion of said cabinet, said entrance opening and said exit opening connecting with said longitudinal opening so that a hand-held suspended article can be passed in said cabinet by a person holding said article outside said cabinet; means arranged within said cabinet for generating sensing radiation in a direction transversely to movement of said hand-held article; and means for detecting said radiation after passage through said article and for recording resulting information.
Claim 2
Dependent Claim
131 words
Apparatus for inspecting an article comprising a longitudinally extending cabinet having top and bottom walls, oppositely disposed side walls, and oppositely disposed end walls; a longitudinally extending slot-like opening in said cabinet adjacent a corresponding edge of said top wall and a side wall; an entrance opening at one portion of said cabinet and an exit opening at another portion of said cabinet, said entrance opening and said exit opening connecting with said longitudinal opening so that a hand-held suspended article can be passed in said cabinet by a person holding said article outside said cabinet; means arranged within said cabinet for generating sensing radiation in a direction transversely to movement of said hand-held article; and means for detecting said radiation after passage through said article and for recording resulting information.
