When a cartridge having a light-shielding lid at the film entrance / exit is used as described above,
A method has been proposed in which a light-blocking lid is closed in a film unit with a lens or a camera after shooting is finished, and then a cartridge is taken out. As an example, an opening / closing mechanism that interlocks with the light-shielding lid of the cartridge is provided inside the film unit with a lens or the camera, and a jig is inserted from the outside to operate the opening / closing mechanism to close the light-shielding lid before taking out the cartridge. There is a way.

However, providing the opening / closing mechanism increases the number of parts and inevitably increases the cost. Aside from general cameras that have a margin of cost to some extent, in a film unit with a lens, which is characterized by being simple and inexpensive, increasing the cost is a serious problem.

Further, a space for the opening / closing mechanism is required, which hinders miniaturization.

Further, even if an opening / closing mechanism is provided, if the cartridge is taken out without forgetting to close the light shielding lid, the film may be exposed to light.

The present invention has been made in view of the above problems, and is a method for taking out a cartridge, which does not require an opening / closing mechanism suitable for a film unit with a lens.

As shown in FIG. 4, the cartridge 8 includes a cartridge body 80, a hoisting spool 81, a film F wound around the hoisting spool 81, and a film inlet / outlet port 8.
2 and a light-blocking lid 83 for blocking the light.
It is configured as disclosed in Japanese Patent No. 75336. The light shielding lid 83 is rotatably fitted in the cartridge body 80, and a key 84 is formed at one end of the light shielding lid 83. In the figure, the light-shielding lid 83 is in a state in which the film entrance / exit 82 is opened and the film is fed. On the other hand, when the light shielding lid 83 shields the film entrance / exit 82, the film 84 is closed by driving the key 84 to rotate the light intercepting lid 83 about 90 ° in the counterclockwise direction.

Therefore, the cartridge 8 used in the present invention
Is different from the conventional film cartridge which has a telemp at the entrance / exit of the film, the light-shielding lid 8 is always used when it is taken out into the bright room.
3 needs to shield the film entrance / exit 82 from light.

When the above-described lens-equipped film unit 1 is shipped, the light-shielding lid 83 opens the film inlet / outlet 82 so that the film can be fed. Also,
The film unit with lens 1 according to the present invention does not have any closing mechanism for closing the light shielding lid 83. Therefore, after taking a picture using the lens-equipped film unit 1 and returning it to a laboratory or the like, the cartridge 8 is taken out of the lens-equipped film unit 1 in a dark room, and the light-shielding lid 83 of the cartridge 8 is closed. After that, the cartridge 8 is carried to a bright room and set in an automatic developing machine to perform development.

As described above, since the rotary jig 51 may be inserted regardless of the position of the key groove 84a in the rotational direction, the work can be easily performed even in a dark room.

As another embodiment, the rotary jig shown in FIG. 6 can be used. 6A is an enlarged perspective view before the rotary jig is crimped onto the cartridge, and FIG. 6B is an overall perspective view before the rotary jig is crimped onto the cartridge.
(C) is an overall perspective view in which the rotating jig is pressure-bonded to the cartridge.

The rotary jig 61 has a cylindrical end portion 62 made of an elastic member such as rubber at the tip. When the end portion 62 is brought into contact with the key 84 of the cartridge 8, the end portion 84b of the key 84 is crimped, the key 84 is rotated by a frictional force regardless of the position of the key groove 84a, and the light shielding lid 83 can be closed. it can. As described above, since the rotary jig 61 may be pressure-bonded regardless of the position of the key groove 84a in the rotation direction, the work can be easily performed even in a dark room.

Further, another embodiment is shown in FIG. Figure 7
7A is a perspective view before the pressing jig is pressed against the cartridge, and FIG. 7B is a perspective view in which the pressing jig is pressed against the cartridge.

In both figures, the light-shielding lid 83 protruding outward from the film inlet / outlet 82 of the cartridge 8 is pressed from the side surface by the tip of the inclined surface 71a formed on the pressing jig 71, whereby the light-shielding lid 83 is pressed. 83 is rotated and closed. As described above, since the pressing jig 71 may be directly pressed at an arbitrary position in the longitudinal direction of the light shielding lid 83 without using the key 84, the operation can be easily performed even in a dark room.

In addition, there is also a method in which the light shielding lid 83 is wound in the developing cartridge without being closed in a dark room. FIG. 8 is a diagram showing that the film is wound around the developing cartridge from the photographed cartridge. 90 is a developing cartridge 1
This is an example, and is similar to the developing cartridge filed by the applicant in Japanese Patent Application No. 6-279901. The film F pulled out from the cartridge 8 taken out from the film unit with lens in the dark room is inserted into the developing cartridge 90 and wound around the reel 91. In addition,
The pressure roller 9 so that the reel 91 can be reliably wound up.
