Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A magazine for dispensing light-sensitive materials comprising a tubular body having two side portions and side plates covering each of said two side portions of said tubular body; said tubular body being formed by bending a sheet material having folded portions at both ends thereof so as to form a slit between said both ends and having an upper part of the magazine formed by a portion of the bent material in a region adjacent one of said both ends, a front wall part of the magazine formed of a portion of the bent material in a region adjacent the other of said both ends, wherein a forehead portion having a upper edge and a lower edge is formed by the bent material in an area between said upper part and one of said folded portions positioned at said one of said both ends of the upper part, said forehead portion having a plane essentially parallel to said front wall part and a central portion of one of said upper edge and said lower edge thereof being bulged outwardly in a direction parallel to said plane so as to form an arc extending lengthwise of the slit.
Claim 2
Dependent Claim
197 words
A magazine for dispensing light-sensitive materials comprising a tubular body having two side portions and side plates covering each of said two side portions of said tubular body; said tubular body being formed by bending a sheet material having folded portions at both ends thereof so as to form a slit between said both ends and having an upper part of the magazine formed by a portion of the bent material in a region adjacent one of said both ends, a front wall part of the magazine formed of a portion of the bent material in a region adjacent the other of said both ends, wherein a forehead portion having a upper edge and a lower edge is formed by the bent material in an area between said upper part and one of said folded portions positioned at said one of said both ends of the upper part, said forehead portion having a plane essentially parallel to said front wall part and a central portion of one of said upper edge and said lower edge thereof being bulged outwardly in a direction parallel to said plane so as to form an arc extending lengthwise of the slit.
