The invention of the present document is an improved disc singulator (10) for use in singulating and delivering to a test site (12) an integrated circuit device (14) to be tested by a tester mechanism. The singulator (10) includes structure to positively hold the device (14) within slots (64) formed in the periphery (52) of the disc (10) as it is rotated. A main body portion (16) of the device (14) is, thereby, held so that a plane defined by the main body (16) is oriented generally orthogonal to a plane defined by the disc (10). Additionally, the device (14) is held at an appropriate radial location with respect to the disc (14) so that, as the disc (10) rotates the device (14) carried thereby through a slit (40) in a printed circuit board (36) at the test site (12), contacts (26) of the device (14) will engage corresponding probes (38) at the test site (12). A wire spring (124) is employed to orient the main body portion (16) of the device (14) within a slot (64) in the disc (10) to prevent canting of the device (14). A plunger (86) and latch (132) are employed to assure proper radial positioning.

Photographic print paper magazine with multi-position handle

A photographic printer makes a plurality of exposures on photographic print paper. The size of the exposure is determined by a mask. The proper feed length of the print paper is determined by indicia associated with the mask.

Paper feed system for photographic printer

A photographic printer has a punch marking system for placing cut and end-of-order marks on the photographic paper. The punch marking mechanism is adjustable to accommodate different widths of print paper. The punch marking mechanism includes guide rods which are positioned transverse to the path of the print paper. First and second carriage assemblies are movable along the guide path defined by the guide rods on opposite sides of the center line of the paper path. A lead screw moves both the first and second carriage assemblies along the guide path in an essentially symmetrical manner about the center line of the paper path. The punches or other marking devices are carried on the first and second carriage assemblies.
