Abstract
An apparatus for mounting a film magazine into camera includes a magazine receiving casing which is adapted to receive a film magazine therein and which includes a drive shaft for driving a film winding shaft of the magazine for rotation. The casing is disposed in a tiltable manner with respect to a camera body to permit the insertion or removal of a film magazine into or from the casing.
Claims27
Apparatus, comprising:
- a camera body having a film chamber formed therein;
- a magazine receiving casing for receiving a film magazine therein;
- mounting means for tiltably mounting said casing in said film chamber so that it is movable between a first position wherein said casing is wholly located in said chamber and a second position wherein said casing extends at least partially outside of said camera body to permit insertion or removal of a film magazine;
- and
- a drive shaft extending into said casing and adapted to engage a film shaft of a film magazine when a film magazine is located in said casing, said drive winding shaft tilting with said casing.

Apparatus comprising:
- a camera body having a film chamber formed therein;
- a magazine receiving casing for receiving a film magazine therein, said magazine receiving casing having an open top which is channel-shaped in cross-section including an open side which is covered by a stop sheet, said stop sheet providing a grip to enable a user to tilt said casing, said stop sheet being resilient such that it can be pulled away from said casing so as to increase the effective size of said top opening;
- mounting means for tiltably mounting said casing in said film chamber so that is is movable between a first position wherein said casing is wholly located in said chamber and a second position wherein said casing extends at least partially outside of said camera body to permit insertion or removal of a film magazine;
- and
- a drive shaft extending into said casing and adapted to engage a film winding shaft of a film magazine when a film magazine is located in said casing.

Apparatus comprising:
- a camera body having a film chamber formed therein;
- a magazine receiving casing for receiving a film magazine therein;
- mounting means for tiltably mounting said casing in said film chamber so that it is movable between a first position wherein said casing is wholly located in said chamber and a second position wherein said casing extends at least partially outside of said camera body to permit insertion or removal of a film magazine;
- a drive shaft extending into said casing and adapted to engage a film winding shaft of a film magazine when a film magazine is located in said casing;
- and
- said casing being urged towards said second position by the resilience of a leaf spring disposed below said casing;
- and
- a spring member mounted at a position on said camera body which will cause said spring member to engage an upper end of a film magazine which is received in said casing for constraining said casing from angular movement under the resilience of said leaf spring, said spring member comprising a second leaf spring which forms a movable electric contact disposed adjacent to a fixed contact, said movable connact being urged into contact with said fixed contact when a film magazine is received in said casing to provide a switching action for a detection circuit which indicates the presence of a film magazine in said casing.
