摘要

A shutter for a cartridge is adapted to be mounted on a cartridge case of the cartridge so as to open and close a head insertion hole in the cartridge case housing a recording medium therein. The shutter is made of a synthetic resin and includes a pair of opposed flat plate portions (6) and a connecting plate portion (7) interconnecting the pair of flat plate portions at one end edges of the flat plate portions. The thickness of each of the flat plate portions increases progressively from the one end edge thereof, disposed adjacent to the connecting plate portion, toward the other end edge of the flat plate portion remote from the connecting plate portion. There is also disclosed apparatus for molding this shutter. <IMAGE>
