ABSTRACT:
A transport chain includes chain links having respective nests for receiving spindles, each supporting a bank of film discs. The chain is advanced to convey spindles received in the nests successively along a transport path to photofinishing equipment, for example. A stop member is disposed in the transport path proximate the photofinishing equipment to stop the forwardmost spindle as the chain continues to advance. The forward end of a rocker arm is raised by the forwardmost spindle stopped in the transport path, which lowers a rearward end of the rocker arm into the transport path to block the next following spindle from advance with the chain. In this way, separation is maintained between the two banks of film discs supported on the forwardmost and next following spindles. Transfer of the forwardmost spindle from the chain to the photofinishing equipment allows the forward end of the rocker arm to be lowered, which raises the rearward end of the rocker arm from the transport path to free the next following spindle for resumed advance with the chain.
