Abstract:
A supply real for motion picture film has a socket which can receive the free end of the innermost convolution of film, and an integral retaining device which can be readily broken off and has a clamping portion insertable into the socket to clamp the free end of the innermost convolution against the reel. The retaining device is further provided with an additional portion which extends beyond the socket when the latter received the clamping portion to serve as a means for preventing improper insertion of the reel into certain types of cassettes. The additional portion can be broken away from the clamping portion so that the reel, with the clamping portion inserted into the socket and with the additional portion broken away, can be inserted into cassettes of another type which do not permit insertion of reels with the additional portions of retaining devices extending beyond the sockets.
Abstract:
A still camera for use with holders for percussively ignitable flash lamps wherein the holder is connectable to a socket in or on the body of the camera and the socket is indexible by the film transporting mechanism through the intermediary of motion transmitting means having a reciprocable, pivotable and/or axially movable slide or a gear train. The condition of that flash lamp which faces the subject is scanned by a lever which prevents the motion transmitting means from indexing the socket when an unfired lamp faces the subject or when the holder is detached from the socket.
