スが発生するといった問題点があった。In conventional cameras that use cartridge film, loading the film is quite troublesome, and in order to improve this, various proposals have recently been made for so-called easy-to-load film cameras that allow for easy film loading. ing. The present applicant also proposed one of this kind of proposals by opening a small back cover on the back side that corresponds to the cartridge chamber of the camera and inserting the cartridge into the cartridge chamber without worrying about the length of the film that has been pulled out in advance. We have already filed an application for a camera that automatically feeds a part of the film leader into the camera body and then automatically feeds it into the spool chamber by simply closing the back cover. . However, in the camera of this application, the cartridge may be loaded with the film drawer opening facing upward (towards the back of the camera).
In such cases, there were problems in that the back cover would not close or the film would not be properly fed into the spool chamber, resulting in film loading errors.

通用されれば好適なものである。The present invention solves the above-mentioned conventional drawbacks.The present invention corrects the position of the cartridge, especially the position of the film drawer opening, in conjunction with the opening/closing operation of the back cover when loading the film, thereby eliminating the occurrence of film loading errors. The object of the present invention is to provide a camera in which the present invention can be used, and it is particularly suitable if it can be used in the above-mentioned simple film loading type camera.

Reference numeral 12 denotes a connecting lever that is bent into a substantially dogleg shape when viewed from above, and a shaft 13 inserted through a hole 12a bored in the approximate center of the lever 12 is fixed to the camera body 1, thereby forming the connecting lever. 12 is pivotally attached to the camera body 1 so as to be rotatable. A The connecting lever 12 has a first arm part 12b and a second arm part 12c integrally on both sides (left and right sides in FIG. 5) of the glaze 13,
The first arm 1 is located near the free end of the first arm 12b.
An elongated hole 12d extending substantially parallel to the outer surface of the second arm 12c is provided near the free end of the second arm 12c, and an elongated hole 12e extending substantially parallel to the outer surface of the second arm 12c is provided near the free end of the second arm 12c. Further, the back cover connecting pin 11 is provided on the first arm portion 12b.
A step portion 12f that is bent to the side is formed. Reference numeral 14 denotes a shaft 15 disposed within the cartridge chamber la and fixed to the camera body 1 concentrically with the winding shaft PI (FIG. 6) of the cartridge P. As shown in FIG. 4, the cartridge correction lever 14 has a flat, circular disk portion 14a, and has an oval cross section so as to be housed in a space between the lower end of the cartridge P and the inner wall surface of the cartridge chamber 1a. Connecting part 1 that bends into a single character shape
4b, and an operating portion 14c that is continuous with the connecting portion 14b and bent at a substantially right angle. An operating bottle 16 is installed in a substantially vertical direction at a suitable position on the connecting portion 14b side of the disc portion 14a, and the operating bottle 16 is inserted into a long hole bored in the lower part of the cartridge chamber 1a as shown in FIG. (not shown) and extends downward. The free end of the operating bottle 16 is inserted into the elongated hole 12e of the connecting lever 12, and the free end of the back cover connecting bottle 11 is inserted into the elongated hole 12d.

Pはパトローネla内における正規位置に保持される。Next, the operation of the camera of the present invention having the above configuration will be explained. As shown in FIG. 1, when the back M5 is opened, the operating portion 14c of the cartridge correction lever 14 approaches the inner wall side of the back cover pivot portion 1b of the camera body 1 in conjunction with this opening operation. 7 In this state, if the user loads the cartridge P into the cartridge chamber 1a with its film drawer opening P2 facing upward as shown by the dashed line in FIG. The following operations are performed. In other words, when the back M5 moves to the closing operation, the back M5 rotates clockwise around the shaft 7, and accordingly, the back cover connecting pin 11 also rotates clockwise around the shaft 7. . Then, the back cover connecting pin 11 presses the first arm portion 12b of the connecting lever 12 downward, so that the connecting lever 12 rotates counterclockwise about the shaft 13. On the other hand, since the operating pin 16 of the cartridge correction lever 14 is fitted into the elongated hole 12e, the cartridge correction lever 14 rotates clockwise about the shaft 15 as the connecting lever 12 rotates counterclockwise. do. At this time, each of the pins 11, 16 slides within the elongated holes 12d, 12e, so that the operation is performed smoothly. As the cartridge correction lever 14 rotates clockwise, the action portion 14c of the lever 14 comes into contact with the flat surface P3 of the cartridge P, and further rotates the cartridge P clockwise about the winding shaft P. to press. When the back cover 5 is completely closed as shown in FIG. 5, the action part 14c and the plane part P3 are approximately parallel to the surface of the aperture (not shown) of the camera body 1, and the cartridge P is at its normal position in the cartridge la. Retained.

の説明は省略する。That is, the film drawer opening P2 of the cartridge P is oriented in a direction substantially parallel to the surface of the aperture (not shown), and the film F is fed without waste to the spool chamber (not shown). In addition, when releasing the back M5, the operating portion 14c of the cartridge correction lever 14 is
is retracted to a position where it does not interfere with the loading of the cartridge P, but its explanation will be omitted.

メラに適用すれば好適である。As explained above, according to the camera of the present invention, the position of the cartridge is adjusted in conjunction with the opening/closing operation of the back cover when loading film.
In particular, the position of the film drawer opening has been corrected, which eliminates film loading errors such as the back cover not closing when loading a cartridge with the drawer opening facing upwards, making it possible for even people who are unfamiliar with cameras to do so. Film can be loaded easily and reliably. In particular, you can open the small back cover on the back side that corresponds to the cartridge chamber of the camera, put the cartridge into the cartridge chamber without worrying about the length of the film that has been pulled out, and close the back cover. It is suitable for application to a camera in which a portion of the leader is once wound into the camera body and then automatically fed to the spool chamber.
