专利汇可以提供Camera capable of combination with a power-driven housing for film-rewinding专利检索，专利查询，专利分析的服务。并且A camera of the type which uses a magazine provided with a supply spool having the opposite ends thereof exposed out of the shell of the magazine, a slit for passing a film therethrough and capable of being opened and closed, and a slit-operating means for opening and closing the slit provided in one end face of the magazine. The camera includes an aperture formed below a film magazine containing chamber, and a light-intercepting cover for covering the aperture to prevent the entry of any extraneous light therethrough while enabling the opening and closing of the camera''s backplate and the slit of the film magazine, whereby power-driven film-rewinding operation can be accomplished by replacing the light-intercepting cover with power-driven filmrewinding means, and the camera''s backplate and the slit of the film magazine can be opened and closed with the power-driven film-rewinding means mounted on the camera. The camera may further include a retaining member for retaining the lightintercepting cover so as to inhibit the removal of such cover unless the camera''s backplate is opened, and a release member for releasing the light-intercepting cover from its retained position provided in the film magazine containing chamber.，下面是Camera capable of combination with a power-driven housing for film-rewinding专利的具体信息内容。

权利要求

1. A camera using a magazine provided with a supply spool having the opposite ends thereof exposed out of the shell of the magazine, a slit for passing a film therethrough and capable of being opened and closed, and a slit-operating means for opening and closing said slit provided in one end face of the magazine, the combination comprising: a film housing for containing said magazine therein; a first driving member disposed in said film housing and manually operable to rotate said spool for film rewinding; a control member disposed in said film housing and having an engaging portion engageable with said slit-operating means, said control member being movable so as to provide said slitoperating means with a motion necessary to open and close said slit, said control member having an aperture formed in a portion thereof on the extension of the axis of said spool; and a covering member for opening and closing said aperture of said control member and capable of completely intercepting any light incident on said aperture when said aperture is closed, said covering member including a first clutch means engageable with said control member when said aperture is closed, said first clutch means being capable of providing said control member with a motion necessary to drive said slit-operating means through a manual actuation imparted from the exterior of said camera housing.

2. A camera as defined in claim 1, wherein the combination further comprises a power-driven housing which may be detachably mounted on said camera and when mounted on said camera, can completely intercept any light incident on said aperture of said control member, said power-driven housing including: a second driving member engageable and disengageable with said spool end having said slit-operating means when said power-driven housing is mounted on said camera, said second driving member being capable of rOtating said spool with a motive power during power-driven film rewinding; and a second clutch means engageable with said control member when said power-driven housing is mounted on said camera, and capable of providing said control member with a motion necessary to drive said slit-operating means through a manual actuation imparted from the exterior of said power-driven housing.

3. A camera as defined in claim 1, wherein the combination further comprises a deformable intercepting member having a central opening dimensioned sufficiently to provide said aperture of said control member, said intercepting member being interposed between said control member and said covering member when said camera is used without said power-driven housing combined therewith, said intercepting member being interposed between said control member and said power-driven member when said camera is used with said power-driven housing combined therewith.

4. A camera as defined in claim 1, wherein the combination further comprises a first locking means capable of blocking the opening action of said covering member independently of its own closing action, and a releasing means capable of releasing said blocking action of said first locking means with respect to said covering member, said releasing means being manually operated only within said film housing.

5. A camera as defined in claim 1, wherein said film housing has a wall portion which can be opened and closed to permit the loading and unloading of said magazine, and said camera further includes a second locking means disposed in said film housing and capable of locking said wall of said film housing in closed position, said second locking means being displaceable to a position for opening said wall of said film housing in response to the movement of said control member.

6. A camera as defined in claim 2, wherein said second driving member is movable along its own axis with respect to said power-driven housing when engaging said spool.

7. A camera as defined in claim 4, wherein said releasing means is disposed in said covering member.
