Sound-film camera

In a cine camera, in combination:

• a casing adapted to accommodate a motion-picture film having a sound track, said casing being provided with an exposure gate and sound-recording means;
• drive means in said casing for transporting said film past said exposure gate and said sound-recording means, said drive means including a continuously rotatable capstan and a pinch roller adapted to clamp said film therebetween;
• energizing means for said drive means including manually operable trigger means;
• relatively displaceable support means for said pinch roller and said capstan;
• and
• an external actuating member on an outer surface of said casing coupled with said support means and manually operable independently of said trigger means for relatively displacing said pinch roller and said capstan from a more widely separated normal position into a relatively closed spaced alternate position preparatorily to operation of said trigger means, said actuating member comprising a spring-loaded mounting for an eyepiece of a viewfinder engageable by the head of a user holding said casing.

• and
• an energizing circuit for a component intervening in the taking of motion pictures, said circuit including switch means coacting with said support means for preventing the energization of said components in said normal position.
