Abstract: An opto-mechanical platform for supporting truncated optical elements having at least one substantially flat side surface is disclosed. In one particular exemplary embodiment, the opto-mechanical platform may be realized as an apparatus for supporting truncated optical elements having at least one substantially flat side surface. Such an apparatus may comprise a platform having a substantially flat surface area for supporting the substantially flat side surface of the truncated optical elements. Such an apparatus may also comprise at least one substantially vertical wall formed on at least a portion of the platform for providing mechanical rigidity to the platform.

Abstract: An integral actuator/reel lock/spring for a video cassette is described, including: (a) a lock body having a first end and a second end, an inclined opening at the first end to receive a tape player/recorder pin, lateral wings, angled grooves and a lead in for a self-centering rib in the cassette base; and (b) a spring bar connected centrally at the second end of the lock body, the spring bar including a pawl and a lower dog leg combination formed at each end. The lock body is received in the cassette base in an area defined by: (a) a first, elongated, central portion having parallel side walls, between which is formed a self-centering rib; and (b) a pair of lateral, substantially triangular walled portions, each spaced from the central portion.
