うになつている。(Prior art) In Fig. 5, 1 is the camera body, 2 is the back cover,
3 is a take-up spool; 4 is a sprocket; 5 is a film that is wound onto the take-up spool 3 via this sprocket; 6 is a film roller that guides the film 5; 7 is a free end on the outer periphery of the take-up spool 3; A film guide plate 8 has its base rotatably pivoted to the camera body 1 so that the film guide plate 7 is in contact with the film guide plate 7. When loading the film, the film 5 is attached to the sprocket 4.
The perforation is fed onto the outer periphery of the take-up spool 3 in the same direction as its rotating direction, and the perforation is engaged with the claw 3' of the take-up spool 3, and then wraps around the outer periphery of the take-up spool 3 and its tip. is pressed against the outer periphery of the take-up spool 3 by the free end of the guide plate 7, and as the take-up spool 3 rotates, the film is wound around it and winding is continued.

３′と係合せず巻取り不能となるおそれがあつた。(Problem to be solved by the invention) However, in the conventional device, when the sprocket 4 is rotated by the take-up lever and the film 5 is loaded, the film 5 moves along the outer circumference of the take-up spool 3 in the direction of rotation of the take-up spool 3. The perforation of the film 5 enters between the camera body 1 and the take-up spool 3 in the opposite direction to the rotational direction of the take-up spool 3, and the perforation of the film 5 engages with the claw 3' of the take-up spool 3. There was a risk that winding would not be possible due to misalignment.

A take-up spool, a film guide plate whose base is rotatably supported on the camera body, and a film guide plate of the take-up spool such that the free end of the film guide plate is fitted into and in contact with the small diameter portion of the take-up spool. The film guide plate includes a spring for constantly restraining the film in the same direction as the rotation direction, and when the film enters around the take-up spool in a direction opposite to the rotation direction of the take-up spool, the film guide plate prevents the advance of the film. The perforation of the film comes to be engaged with the claw of the take-up spool in this blocked state.

よつて巻き取られるようになる。(Function) In the simple film loading device of the present invention, when the film fed by the sprocket advances in the opposite direction to the rotational direction of the take-up spool and enters between the body and the take-up spool, the leading end of the film touches the film guide plate. At this time, the perforation of the film engages with the claw on the outer periphery of the take-up spool, and the film is taken up by the take-up spool.
（実施例） 以下図面によつて本考案の実施例を説明する。(Example) Embodiments of the present invention will be described below with reference to the drawings.

位置関係となるようにする。（従つて第１図〜第
３図の場合には前記ガイド板７は巻取スプール３
の左側に位置される）。 In the present invention, when the take-up spool 3 rotates counterclockwise as shown in Figs. 1, and the guide plate 7 is controlled by a spring 8 to rotate in the same counterclockwise direction as the take-up spool 3, so that the free end of the guide plate is rotated by the spring 8.
so that it is pressed against the outer periphery of the take-up spool 3. (Accordingly, in the case of FIGS. 1 to 3, the guide plate 7 is connected to the take-up spool 3.
).
又巻取スプール３の外周の爪３′に隣接した部

イルム５の何れかの部分のパーフオレーシヨンが

て容易に係合されるようにする。 A small diameter portion 9 is formed on the outer periphery of the take-up spool 3 adjacent to the pawl 3', and the free end of the guide plate 7 contacts the take-up spool 3 within this small diameter portion 9. As a result, the guide plate The upper surface of the film 5 is at a sufficiently lower level than the claw 3' of the take-up spool 3, and therefore, if the leading edge of the film 5 hits this part, the perforation of any part of the film 5 will not reach the take-up spool 3. It is made very easy to engage with the pawl 3' by the rotation of the holder.

るようにされる。 Since the simple film loading device of the present invention has the above-described configuration, the leading end of the film 5 enters between the camera body and the take-up spool 3 in the opposite direction to the rotational direction of the take-up spool 3, as shown in FIG. Even if the film 5 is fed by the sprocket 4, its advance is blocked by the guide plate 7, and in this blocked state, the perforation near the tip of the film 5 engages with the claw 3' on the outer periphery of the take-up spool 3. Therefore, the perforation of the film 5 engages with the pawl 3' of the take-up spool 3 as shown in Figure 2, and since the spool 3 is rotating counterclockwise, the perforation of the film 5 engages with the claw 3' of the take-up spool 3 as shown in Figure 3. After the traveling direction of the film 5 is reversed, the film 5 is wound around the outer peripheral surface of the take-up spool 3.
