POSITIONING APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus for reciprocatively positioning an article or work object (e.g. an inspection sample or test probe) in precise relation to two separated work stations. The article to be positioned is held in a first carrier having a cam- follower attachment. The first carrier is supported shift- ably on a second carrier. The second carrier can be recip- rocated perpendicular to the plane of the work stations. The cam follower of the first carrier is captured movably in a cam track groove of a stationary plate having two cam track grooves associated with respective said stations. A two- position rotatable cam forms a linking channel between the two tracks. Upon completion of a work operation at one of the stations the second carrier is reciprocated. This moves the cam follower of the first carrier up along one track and one associated surface of the cam to a reversing point above and beyond that surface, and then down along another surface of the cam into the other track; thereby transferring the work object to the other work station. The follower move- ment along said another surface rotates the cam so that on a next reciprocation of the second carrier the cam follower rides up said another surface to said reversing point and down the one surface into the one track; reversely tipping the cam to its original position as it rides along said one surface. -1-
