Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a film crimping mechanism for mounting a crimping plate for obtaining the flatness of a photographic film on the back cover side.

[Prior Art] A roll film as a photographic film is a soft film that bends easily by itself, and cannot secure a correct position by itself. Therefore, by pressing a crimping plate with good flatness and sufficient rigidity against the camera body with a spring and pressing it from the back of the photographic film, the tunnel interval formed by the crimping plate and the film rail is correctly positioned and the flatness is maintained. It is like this.

There are various types of attachment of the crimping plate. For example, as in Japanese Utility Model Laid-Open No. 2-36827, the crimping plate is provided with a projection and a plastic spring member provided on a plastic member supporting the crimping plate. A plate that is assembled and fixed and is elastically held by a spring, or a crimp plate that is elastically deformable as in Japanese Utility Model Laid-Open No. 64-43340, and that crimp plate is elastically deformed to move the crimp plate. A structure in which the crimping plate is configured to move in the direction along the inner wall surface of the back cover main body beyond the restricting protrusions to be blocked, and is elastically held by a spring, or the actual open Sho 61-6543.
There is one such as No. 8 in which a crimping plate is held on the back cover base plate, the back cover base plate is fastened and fixed to the back cover with screws, and the crimping plate is elastically held on the back cover.

[Problems to be Solved by the Invention] In the Japanese Utility Model Laid-Open No. 2-36827, the plate-shaped spring portion is bent by the protrusion provided on the pressure-bonding plate when the pressure-bonding plate is attached to or detached from the back cover. The durability of the part is reduced. Further, when removing the crimping plate, it is necessary to apply a force to the plate-shaped spring portion by a fine rod-shaped jig or the like to bend the plate-shaped spring portion to a position where it does not interfere with the lower side of the protrusion, which is troublesome. Further, the hook portion of this crimping plate is engaged with the hook portion of the pressure plate supporting member so that it will not come off even if the reaction force of the spring is generated in the crimping plate, but the portion of the hook portion that holds this crimping plate. Then, the portion where the reaction force is generated by the spring is distant from each other, and a force for bending the crimping plate is generated, which may deform the crimping plate. Further, when the crimping plate is attached to or detached from the back cover, the spring that elastically holds the crimping plate may be deformed or bent. Further, since there is no means for holding the spring, the crimping plate may drop and be lost when it is attached to or detached from the back cover.

Also, in the case of Japanese Utility Model Laid-Open No. 64-43340, the crimping plate is elastically deformable, and when the crimping plate is attached to and detached from the case back, the crimping plate may be deformed. . Further, when the crimping plate is attached to or detached from the back cover, the spring that elastically holds the crimping plate may be deformed or bent. Furthermore, since there is no means for holding the spring only by inserting it into the receiving hole, it may drop and be lost when the pressure plate is similarly attached to or detached from the back cover.

In the case of No. 61-65438, the back cover base plate is held and the back cover base plate is fastened and fixed to the back cover with screws. , Could not be removed. Also, it is necessary to attach a coil spring to the locking pin of the crimping plate held on the back lid base plate to elastically hold the crimping plate on the back lid side. A simple and reliable mounting mechanism is desired because it requires labor and the coil spring may fall during assembly.

The present invention has been made in view of the above point, and the crimping plate can be easily and surely attached, the workability of assembling is improved, and the crimping plate is repeatedly attached and detached without deformation. However, it is an object of the present invention to provide a camera having a film crimping mechanism in which flatness is maintained and an elastic elastic body that elastically supports the crimping plate is not deformed and does not drop when the crimping plate is assembled.

[Means for Solving the Problems] In order to solve the above problems, a camera having a film crimping mechanism of the present invention includes a film crimping portion, a foot portion connected to the film crimping portion at one end, and a foot portion other than the foot portion. A crimping plate integrally formed with a locking portion located at an end and an engaging portion located on the back cover for engaging with the locking portion, the film crimping portion and the locking portion of the foot portion A stretchable elastic body that is wound between the elastic member and a portion, and the stretchable elastic body is provided with a receiving portion provided on the back cover in a state where the locking portion and the engaging portion are engaged with each other. Between the receiving part provided in the film pressure bonding part,
It is characterized in that it is elastically retained.

[Operation] According to the present invention, since the stretchable elastic body is wound around the foot portion of the crimping plate and the locking portion is provided on the foot portion, the stretchable elastic body is reliably held by the foot portion, and the crimping plate is provided. The elastic elastic body does not drop from the foot when attaching or detaching the back cover to the back cover, and is easy to handle.

Also, when the crimping plate is attached to or removed from the back cover, the elastic elastic body is wrapped around the foot of the crimping plate, so the elastic elastic body only expands and contracts in the longitudinal direction of the foot. The elastic body is restricted from being deformed or bent in the left-right direction in FIG. Therefore, the position of the stretchable elastic body is substantially constant at any foot portion of the crimping plate, the elastic force to the film crimping portion becomes uniform at each foot portion, and the flatness of the crimping plate is maintained.

Further, since the stretchable elastic body is located in the vicinity of the foot portion of the crimping plate, the urging force of the stretchable body acts near the foot portion of the film crimping plate, and the flatness of the crimping plate is maintained.

Further, since the stretchable elastic body is elastically held between the receiving portion provided on the back cover and the receiving portion provided on the film pressure bonding portion,
It is possible to prevent the expansion and contraction elastic body from being displaced in the left-right direction in FIG.
