ABSTRACT:
A splicer bed has a leader support on a top thereof. An opening is provided in one end of the leader support. A knife mounting base is arranged to project from the opening and is provided at one end with a cartridge holder. The knife mounting base has a leader positioning head provided on the other end thereof for determining the position of a leader. A stationary knife is mounted to the leader positioning head. A movable knife is mounted for pivotal movement to the stationary knife. A film holddown plate is pivotably mounted to the knife mounting base. The knife mounting base is provided with a pair of punches which are arranged slidably and can be lowered by the film holddown plate. Before the leading portion of a film is drawn out from a film cartridge loaded in the cartridge holder is held under the film holddown plate, the downward movement of the film holddown plate causes the punches to cut two notches in both side edges of the film. The leading portion of the film is trimmed by the downward action of the movable knife and then is joined by a strip of splicing tape to the leader placed on the leader support.
