ABSTRACT:
An apparatus is disclosed for acquiring, transferring and releasing an object such as a prewound spool of film (10), in which a rotatable frame (410-426) is provided with a slidably mounted block (434) which pivotably supports a pair of gripping fingers (464,466) for holding the object and rotatable cam plate (456) which includes cam slots (448,484,486) operatively associated with followers (454,476,478) on the frame and fingers; so that, upon application of a force (488-510) to the cam plate, the block initially translates away from the frame to a position where the fingers close to grip the object, after which rotation of the frame permits transfer of the object to another location where a reverse force is applied to the cam plate to release the object and translate the block back to its starting position.
