Abstract
The present invention relates to a film magazine having an external cylinder both end surfaces of which are closed by upper and lower covers, and a spool hub rotatably contained in the external cylinder at the axis thereof. The spool hub has a thin winding shaft cylinder having and axial length substantially the same as the axial length of the external cylinder and a projection provided on an upper portion of the inner periphery thereof so as to engage a rewind mechanism of a camera. The winding shaft cylinder has a hollow space longitudinally extending over the interior length thereof. A strobe capacitor as a constituent part of the camera body is disposed in the space so that the space in the camera can be further decreased.
Claims5
A camera comprising:
- a film magazine chamber for releasably containing a film magazine removably inserted into said chamber and having a projection which is inserted into a hollow portion of a spool shaft of the film magazine without affecting rotating operation of the spool shaft by a winding member, the spool shaft of the film magazine being rotatably Contained in the film magazine so as to wind a film thereon and having a cylindrical portion with a hollow interior;
- said projection including a constituent part of an electric circuit in a camera body, said constituent part of the electric circuit being a capacitor.
A camera comprising:
- a film magazine chamber for containing a releasably insertable film magazine;
- said film magazine having a spool shaft;
- and
- a stationary constituent part projecting from one wall of the film magazine chamber and aligned with an axial direction of the spool shaft to be received by and contained in a hollow cylindrical portion provided in the spool shaft of the film magazine without affecting operation of the spool shaft by a winding member;
- and
- said constituent part being a strobe capacitor.
A camera system comprising:
- a camera body;
- a film magazine for releasable insertion into the camera body:
- a film magazine chamber provided in the camera body for receiving the film magazine;
- a spool shaft rotatably provided in the film magazine for winding a film thereon;
- a hollow cylindrical portion provided in the spool shaft;
- a constituent part projecting from one wall of the film magazine room to be received by and contained in the hollow cylindrical portion without affecting operation of the spool shaft by a winding member;
- and
- said constituent part being a strobe capacitor.
