Title: Holding frame for positive film frame
Inventor: HIRASAWA AKIKO
IPC: G03D15/10
Filed: 2000-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a positive film frame holding frame which makes positive film frame numbers immediately identifiable. SOLUTION: The positive film frame holding frame 10 is formed of a pedestal 12 in opaque color and a cap 14 in transparent color by two-color molding.
