摘要

The camera (1) safety lock has three anchoring points two of which form part of a single lock. The lock carried by the camera (1) has lateral movement perpendicular to the axis of the assembly. The lock is held in two catches (15, 16) on the axis of two buttons (8, 9) carried on the rear end of the film loader (2). The third anchoring point (4) placed in the front of the film loader (2) consists of a mortise and tenon type assembly (3, 4). Release of the film loader is achieved by means of push plate (7) which actuates a cam (19) which makes the lock move to a release position. The push plate (7) also frees at the moment of release an ejection button (6) whose spring (r4) was compressed at the moment of film loading. The button (6) permits quick release of the camera loader (2).
