Abstract: An electrophotographic typesetter including a scanning system having a light source, means for receiving said light from said source and rotationally scanning said light through a curvilinear scanning locus, means for receiving said curvilinear scanned light and redirecting the light onto a straight line scanning locus, said redirecting means redirecting the light at an angle to the incident light, said means for producing said curvilinear scanned locus having an axis of rotation, said means for redirecting having a center of curvature, and wherein said straight line scanning locus is on a plane passing through said center of curvature, and perpendicular to said axis of rotation.

Abstract: A self-locking folding leg arrangement which enables extending the leg and automatically locking the leg when the extended position is reached, enables quickly releasing the leg by withdrawing the leg lock against the action of its spring, assures rigidity by virtue of the cooperation of a flange which limits the extent of extension of the leg, while the lock prevents return movement of the leg toward its folded position, and facilitates unlatching or unlocking the leg for folding by virtue of a finger tab on the lock. The leg and lock are each pivotally mounted on parallel axes closely adjacent to and on the same side of a generally flat plate adapted to be secured to the underside of a horizontal support member such as a work bench top or sawhorse top.
