ABSTRACT:
A magazine for light-sensitive materials comprises a tubular body and side plates covering each of both sides of the tubular body. The tubular body is formed by bending a sheet material having folded portions at both ends so as to form a slit between both ends and having such a structure that an upper part of the magazine is formed of a portion of the bent material in a region near one end and a front wall part of the magazine is formed of a portion of the bent material in a region near other end. A cured resin is provided within a space formed between the folded portion positioned at the end of the upper part and a portion of the upper part corresponding to the folded portion. Otherwise, a forehead portion having a upper edge and a lower edge is formed of the bent material in an area between the upper part and the folded portion positioned at the end of the upper part. The forehead portion has a plane essentially parallel to the front wall part and a central portion of at least lower edge thereof being outwardly bulged so as to form an arc.
