ABSTRACT:
A color film supply apparatus has a supply roll holding unused color film. The apparatus simplifies the handling of the color film. For this purpose, the supply roll and a waste roll to hold used film are supported in a cassette-type, portable housing in a manner such that a length of the color film extends between the supply roll and the waste roll and the housing has, between the supply roll and the waste roll, an opening that is at least as wide as the color film and permits free access to both sides of the color film. In addition, a straight edge is located in the section of the housing containing the waste roll and deflects the travel path of the color film.
