PURPOSE:To reduce manufacture cost, to eliminate adverse influence upon an image during photography, and to improve the efficiency of printing operation by providing a picture area which is not sectioned by a picture frame on a film disk surface having metering notches at the outer circumference at equal intervals. CONSTITUTION:When a web consisting of a long-sized film is punched, a center hole for core engagement and inner and outer circumferential notches are punched firstly and a core 12 is fitted in the center hole. Then, the outer circumference of the disk is punched along the outer circumferential notches to form metering notches 13, 13.... The picture area 14 is not sectioned by a picture frame. Thus, part of a shot image is not cut by the picture frame too much, and it is not necessary to consider the picture frame during enlargement by a printer unlike before; the operativity of printing operation is expected to be improve and any claim due to the entry of the picture frame in a print surface, etc., is not made. |
