Description

  The present invention relates to a film holder for holding a photographic film, and more particularly to a film holder for holding a sleeve film cut by connecting a plurality of frames.

  A photographic film such as a negative film or a reversal film is cut into, for example, 6 frames after development to form a sleeve film. When projecting the image of this photographic film with a projector or reading it with a film scanner, use a film holder to remove warpage (curvature in the film width direction) and curl (curvature in the film longitudinal direction) of the photographic film. Be pinched.

Patent Document 1 discloses a film holder having a holder main body and a film pressing member, and holding a photographic film for six frames by using these members. This film holder is intended to securely hold the film with an elastic film pressing member. However, in this film holder, the holder body is made of a rigid material, and the film holding member is made of another elastic material. In addition, the main body and the film pressing member need to be rotatably connected by, for example, a hinge structure including a pin and a hole into which the pin is inserted.
This film holder is used when projecting with a projector, and has a large plate thickness. This is not for storing the sleeve film in the film holder. Further, since two types of materials are used, the material cost is high and it takes time to assemble two parts, and as a result, the manufacturing cost increases.
Conventionally, there has not been a thin and inexpensive film holder not only for projecting with a projector but also for storing a sleeve film in a film holder.
