Abstract

PURPOSE:To prevent the trailing edge part of film from being jammed at the exit of a film chamber even when this part tends to curl by forming a notched part near the exit of the film chamber and forming a step part at the rail-like projected line for supporting the back surface side of the film. CONSTITUTION:Two rail-like projected lines 18 are integrally provided at the part of a back cover 7 covering the back surface of the film chamber 13 so that the back surface of the film may be prevented from being damaged because of that it rubs on the inner wall of the film chamber 13, and the friction of the film with the inner wall of the film chamber 13 is reduced, thereby smoothly feeding the film. The projection 18 supports both side edges of the film housed in a roll state in the film chamber 13 by abutting on the back surface of the film. The notch 18a is formed at one part of the projected line 18 so as to prevent the trailing edge part of the film from being jammed at the film exit of the film chamber 13. Therefore, the film can move to the back surface side.

2. Description of the Related Art A lens-fitted photo film unit is an unexposed roll film with a patrone that is built into a unit body equipped with a simple photo-taking mechanism. It can be carried out.
The lens-fitted film unit uses a 135 film cartridge that conforms to the ISO standard. When the film unit is assembled, the film is pulled out from the cartridge and collected into rolls, which are respectively loaded into the cartridge chamber and the film chamber. Then, when the film is wound up each time a photograph is taken during use, the photographed film is sequentially rolled into the cartridge.

Before loading the film and the cartridge in the unit main body, there is used a film drawing device for drawing the film from the cartridge and collecting the film into a roll. This device is provided with a holding portion for the cartridge and a winding shaft for winding the film, and by driving the winding shaft by locking the leading end of the film coming out of the cartridge onto the winding shaft, While pulling out the film, it is wound around the winding shaft in a roll shape.

When the film drawing device as described above is used, a strong bending is likely to occur at the leading end of the film due to the engagement with the winding shaft, and a winding habit is formed at the center of the film roll. Easy to do. When such a film roll is loaded into the film chamber of the unit body, even if the film roll is loosened a little, the curl remains in the central part, and shooting progresses and the film approaches the final end. In this case, the curled portion may be stuck in the exit of the film chamber, so that the film cannot be pulled out smoothly.

FIG. 4 is a sectional view of the vicinity of a film chamber when a conventional general film unit with a lens is horizontally cut, and shows a state in which the movement progresses to near the final frame. A large part of the film 2 is wound around the film cartridge, and there is room in the inside of the film chamber 3. However, since the rear end of the film 2 has a winding tendency, it is inside the film chamber 3. Film 2 which does not spread loosely
The rear end portion of the film chamber 3 is pulled and moved toward the outlet 3a of the film chamber 3 as it is. As a result, a portion of the film 2 having a curl may be caught at the outlet 3a of the film chamber 3 to increase the winding torque, or in some cases, it may be impossible to wind the film.

The rear cover 7 is integrally provided with a bottom cover 15 for the film chamber and a bottom cover 16 for the film chamber having a projection 17, and the bottom of the chamber 12 and the bottom of the film chamber 13 are light-tight. It is designed to cover. Further, in the portion of the rear cover 7 which covers the back surface of the film chamber 13, the back surface of the film 20 is prevented from being scratched by being scratched by the inner wall of the film chamber 13, and the friction between the film 20 and the inner wall of the film chamber 13 is prevented. Two rail-shaped ridges 18 are integrally provided in order to reduce the amount of the film so that the film can be smoothly fed. The ridges 18 support both side edges of a film 20 housed in a roll in the film chamber 13 from the back side. A notch 18a is formed in a part of the ridge 18, so that the rear end portion of the film 20 will not be clogged with the film outlet of the film chamber 13, as described later.

The operation of the above configuration will be described. Immediately after starting the photographing of the lens-fitted film unit, the film 20 is wound and loosened in the film chamber 13 as shown in FIG. 2, and the back surface of the outermost film is held by the ridges 18 of the rear cover 7 and the inner wall of the film chamber 13. It is in a state of being. Even if shooting progresses from this state and the film 20 runs low, the terminal end 20a of the film 20 moves to the vicinity of the film outlet 13a of the film chamber 13 while the terminal end 20a of the film 20 is hooked on the protrusion 17. The film 20 can be smoothly pulled out toward the exposure position without clogging the film outlet 13a.
