Film Positioning Disc The film positioning disc has cut out sectors which engage the film loading prongs The disc serves as a bearing for the prongs and aligns the film with the film transport mechanism b Lock Assembly The baseplate lock assembly secures the baseplate to the camera and opens the metal film magazine An angled stop limits rotation of the lock assembly and releases the retaining spring of the metal magazine 1 The locking plate is slightly wedged shape When the lock is turned fiom the open to closed position the plate engages a locking bar on the camera s inner housing The wedge shape of the plate pulls the baseplate tight to the camera body Two projections on the locking plate strike the angled stop and prevent rotation of the lock beyond the open or closed position 2 When the baseplate is mounted on the camera the curved edge of the angled stop pushes back the magazine retaining spring and unlocks the magazine A groove in the locking plate engages the magazine inner shell knob When the baseplate lock is turned to the closed position the magazine inner shell is turned to its open position Turning the lock to its open position closes the magazine Removing the baseplate reengages the magazine retaining spring and locks the magazine in the closed position 1 7 Hinged Back Fig 23 The hinged back in addition to opening for camera loading also carries a pressure plate and studs for positioning the film a
48. Pressure Plate When the hinged back is closed a spring pushes the pressure plate against two outer film guides on the inner housing The film rests between the outer guides and on the inner film tracks in the film plane This provides a breathing space and assures smooth transport of the film b Film Positioning Studs When the hinged back is closed the positioning studs rest against the outer edges of the film This holds the film perforations in engagement with the sprocket wheel teeth Section Il EXPOSURE METER 1 8 General General functioning of the exposure meter furnished with the KS 15 4 Still Picture Camera Set is described in TM 11 6720 244 12 paragraph 6 3 Following is supplemental information not contained in TM 11 6720 244 12 a Light Measuring Circuit fig a Light 35 volts Figure a Light Measuring Schematic A photo resistor CdS cell battery and ammeter are in series When the cell is dark it has an infinite resistance and no current flows The resistance of the cell decreases in proportion to the intensity of the light incident to it As light intensity increases current flow increases and is measured by the meter b Battery Test Circuit fig b Figure b Battery Test Circuit Actuating the battery test switch disconnects the CdS cell and substitutes resistor R1 Resistor R2 is placed in series with R1 and the battery The meter is connected across R2 and measures the
