ABSTRACT:
A film splicer including a base body on which two films to be spliced are aligned such that splicing ends thereof make contact with each other, an adhesive tape applied to the splicing ends of the films to join them, and a splicer arm that is folded against the base body to bore sprocket holes by punching members and to cut the adhesive tape by cutting members to a length corresponding to the length in the width direction of the films, wherein the cutting members comprise punches capable of punching out both the adhesive tape and excessive edge areas in the width direction of the films and that are formed with tapered portions having an angle relative to a cutting direction that extends in the longer direction of the films, the tapered portions being formed at both end areas in the cutting direction, whereby edge areas in the width direction of the films spliced together are free of steps.
