摘要
In a film cassette, a spool is supported for rotation in an unwinding direction inside a cassette shell, a convoluted film roll whose outermost convolution is a film leader is coiled about the spool, and a film stripper is located substantially adjacent a passageway to the exterior of the shell to be received between a leading end of the film leader and a next-inward convolution of the film roll responsive to rotation of the spool in the unwinding direction to divert the leading end into the passageway. According to the invention, a protuberance projects from the film leader to lie against the next-inward convolution in order to hold the leading end of the film leader and the next-inward convolution apart to generally ensure the stripper will fit between the leading end and the next-inward convolution.
