DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag with a foldable bone such as a dark bag used for loading a photographic paper in a magazine.

[0002]

2. Description of the Related Art In general, in a magazine type photoprinting machine, a magazine loaded with photographic paper is set in a photoprinting machine to perform printing work. However, when loading photographic paper into a magazine, In order to prevent exposure of photographic paper, the loading operation is performed in a separately prepared dark bag.

In a conventional dark bag, a cloth bag body is provided with an opening which can be opened and closed by a fastener, and a cylindrical arm cover for inserting a hand into the bag body is provided on both sides of the bag body. After the magazine and the photographic paper are accommodated in the bag main body through the opening, the hand is inserted into the bag main body from the arm cover, and the photographic paper is loaded into the magazine in the bag main body. .

However, since the conventional dark bag is formed of a soft cloth and does not have a shape-retaining property by itself, for example, when the photographic paper is loaded in the dark bag, the flexible bag body may be hand or hand-held. There is a problem that the workability is bad because it is entangled with magazines.

[0005] For the above problems, for example,
As shown in Japanese Patent Application Laid-Open No. 8-65047, two bottom plates capable of being folded in two by a hinge, a side frame made of a pipe swingably supported on the bottom plate, and a side frame in the bag body. As shown in Japanese Unexamined Utility Model Publication No. 63-41155, a dark bag which secures a working space in the bag body by providing a foldable frame composed of braces installed between the members. In addition, a connection port is provided in the bag body, a blower fan is connected to the connection port, and by driving the blower fan, a dark bag in which the bag body is inflated into a predetermined shape,
Alternatively, as shown in Japanese Utility Model Laid-Open Publication No. 4-31145, an air filling section is provided by making the side face of the bag body a double structure, and the bag body is three-dimensionally filled by filling the air filling section with air. What has been proposed to be formed has been proposed.

[0006] However, even when the skeleton is first provided inside the bag body, it takes time to assemble or fold the skeleton, and the workability is poor, and the overall weight becomes heavy. In the case of a type in which the bag body is inflated to a predetermined shape by a fan, not only does a blower fan be required separately, but when used, dust blows up inside the bag body due to the wind blown from the blower fan. There is a defect that adheres to the photographic paper, and furthermore, in a dark bag with a part of the bag
It takes time and effort to inject air into the air filling section.

Therefore, Japanese Patent Application Laid-Open No. 10-301254 discloses a flexible bag body formed in a substantially rectangular parallelepiped having four side surfaces and two opposing surfaces, and attached along the periphery of the four side surfaces. By forming a dark bag with a bone bag provided with a mold holding frame made of a spring material, the three-dimensional shape is maintained by the holding frame during use, and the holding frame is stacked into a thin rectangular shape when stored, and further stacked. It has been proposed to twist the holding frame into three rings and fold the whole into a small circle.

However, when the four holding frames are overlapped, there is a problem that the four holding frames become thick and difficult to fold, and the whole becomes bulky, so that further improvement in workability is required.

[0009]
