There are the following problems regarding removal. Since the template member is attached to the photographing screen frame inside the camera, when the template member is attached and detached, external light may reach the inside of the camera. Therefore, if the template member is mounted or removed in a bright place with less than the prescribed number of photographic films photographed, the photographed frames may be exposed.

On the other hand, it is possible to attach and remove the template member in a dark place such as a dark room. However, since there is not always a dark room or the like where the photographing is being performed, the number of photographic films less than the specified number is required. It can be generally said that it is impossible to attach and detach the template member while only taking a picture.

Therefore, according to the prior art, the mounting and dismounting of the template member cannot be performed until the photographing is completed to the specified number and the photographic film is rewound.
If you do not finish the specified number of shots but want to attach or remove the template member, give up the shooting of the remaining unphotographed frames, rewind the photographic film, and replace it with a new photographic film. It is necessary to attach and detach the template member. As described above, the template member according to the related art is difficult to use.
