Abstract
Abstract A negative carrier assembly used with a photographic printer. It provides for quick change of the film feed direction according to the film size and other factors. When changing the negative film feed direction, the mask support plate is removed from the negative mask base, turned by 90 degrees, and re-mounted on the negative mask base. This changes the direction of a film guide groove formed in the negative mask supported on the negative mask base. The negative film is pressed by the negative presser frame mounted on the negative presser arm pivoted together with the holder arm.
