Abstract
An optical scanning apparatus for retrieving digital electronic images representative of opaque and transmissive objects. The apparatus is equipped with an optical switch which is operated by solenoid switches positioned at one end of the scanning apparatus. A scanning camera equipped with transmissive and reflective light sources for illuminating the corresponding objects may be selected by the operator to retrieve images of either the reflective or transmissive object type.
Claims6
In a transmissive/reflective optical scanning apparatus comprising a scanner housing;
- a carriage;
- two rails extending along the length of the housing and adapted to carry said carriage;
- a reflective scanning platform;
- a transmissive scanning platform;
- a scanning camera positioned proximate to said reflective scanning platform and adapted to selectively view said platforms and generate electrical signals representative of the images viewed;
- and a rotatable optical switch, the improvement comprising a first solenoid relay positioned at a first end of said rails and adapted to set up the apparatus in a transmissive scanning mode;
- whereby said first relay causes rotation of said optical switch in a first direction when energized and when contacted by said switch as it moves along and reaches a predetermined position near one end of said rails.
