Abstract
This disclosure relates to an object detector which incorporates a photoelectric detector in the vacuum flow path of a vacuum pickup system to serve as a device to determine whether an object has been successfully engaged, retained and transported by a vacuum orifice, so that transport cycles may be modified or terminated by control circuitry in the event that the object has not been successfully engaged, retained and transported, thereby saving time and reducing damage to object, transport means or the surface to which the object is transported.
