Abstract
Apparatus is disclosed for selectively notching an edge of a material such as photographic film or cutting through the material using the same blade. The material is guided by a path, and the blade is mounted for variable penetration into the path. One or more solenoids are responsive to a first control command for driving the blade a first distance into the path to notch an edge of the material therein, and responsive to a second control command for driving the blade a second distance into the path to cut entirely through the material. The apparatus has particular application as a cutter/notcher for a film recorder.
