Claims

[Scope of utility model registration request]

In a film support driving device that drives an inverted U-shaped film support that has been moved from the top of the supply rail to the supply position using a driving mechanism that moves the film support from the top dead center to the bottom dead center, A film in which a pressing mechanism for pressing the column from the rear side is slidably provided on the guide rail, and is integrally movably connected to a weight that moves in the pulling direction toward the supply position via a connecting member. Strut supply mechanism of the strut driving device.
