Abstract

PURPOSE:To take out the leading edge of a film housed in a film cartridge having an opening/closing cover with easy operation. CONSTITUTION:An inner cylinder 14 having a plane part 22 is inserted in an outer cylinder 12 having a plane part 44 so that it can rotate around an axial line. Teremps 23 and 25 are provided on the opposed surfaces of the plane parts 22 and 44. A dial knob 56 provided with a spool rotating shaft for rotating the spool of the film cartridge is provided on either side of the outer and the inner cylinders 12 and 14, and a knob 36 provided with a gear 34 meshing with a gear for rotating the opening/closing shaft (opening/closing cover) of the film entrance of the film cartridge is provided on the other side thereof. After housing the film cartridge inside, the inner cylinder 14 is rotated and the cover is closed. Since light is shielded by teremps 23 and 25 even when the leading edge of the film is fed to the outside of the container by rotating the knob 36 and opening the opening/closing shaft of the film cartridge, the film inside does not receive the light.

2. Description of the Related Art A film cartridge for storing photographic film has been proposed in which a light-shielding opening/closing lid is provided at the film entrance/exit.

As shown in FIG. 3, this film cartridge 100 has a main body cylindrical portion 1 as a cylindrical body having a substantially cylindrical shape.
02, and a spool 122 for winding a film is arranged in the center of the main body cylindrical portion 102. Both ends of the spool 122 are rotatably supported by the side portions 124 of the main body cylindrical portion 102. Further, recesses 126 are formed at both ends of the spool 122 (only one side is shown in FIG. 3), and a locking protrusion 128 as an engaging portion is provided at the center of the recess 126. . As shown in FIG. 2, the spool 122 protrudes more on the left side of FIG. 2 than on the right side. These recesses 126 and locking protrusions 128
has almost the same structure as the spool of a regular 135 film cartridge, and has the role of engaging with the winding shaft of the camera and a groove (not shown) provided on the winding shaft. A slit 129 is formed in the center of the spool 122, and the rear end of the film is locked in this slit 129.

[0004] Further, the main body cylindrical portion 102 is provided with a slit-shaped film inlet/outlet 104. A light-shielding shaft 106 as a rotatable light-shielding member is arranged inside the film entrance/exit 104, and a slit 108 through which the film 107 is inserted is formed in the light-shielding shaft 106 along the longitudinal direction. Further, a recess 110 is formed in the main body cylindrical portion 102 near the longitudinal end of the film entrance/exit 104, and one end of the light shielding shaft 106 projects into this recess 110. A gear 112 is fixed to the tip of the light shielding shaft 106 that protrudes into the recess 110.
A lever 114 that can be elastically deformed is integrally provided in a part of 12.

A projection 116 is provided on a portion of the lever 114, and this projection 116 is adapted to engage with small recesses 118 and 120 provided in the recess 110. When this protrusion 116 engages with the small recess 118, the slit 108 of the light-shielding shaft 106 corresponds to the film entrance/exit opening 104, allowing the film to be inserted therethrough. In addition, the protrusion 116
When engaged with the small recess 120, as shown in FIG.
The slit 108 of the light-shielding shaft 106 is the film entrance/exit 104
The inside of the main body cylindrical portion 102 is in a light-shielded state without corresponding to the above.

[0006] When developing using a small automatic processor, the leading edge of the film is pulled out from the cartridge containing the photographed film (so-called tongue removal) before development.
The leading edge of the film is connected with tape to a flexible guide plate called a leader, and the leader guides the film into the developing machine to develop the negative. Such photographed film must not be exposed to light fog until the development process is completed.

[0007] The film cartridge 100 of the type that blocks light with the light-shielding shaft 106 has a light-shielding shaft 106.
Unless the slit 108 of 06 and the film entrance/exit 104 are made to correspond to each other, tongue extraction cannot be performed. However, in this film cartridge 100, when the slit 108 of the light-shielding shaft 106 and the film entrance/exit 104 correspond to each other, light enters the interior, so this work of removing the tongue must be done in a dark room or dark box, which reduces efficiency. I can't do tongue-out work well.
