Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 95 words
A camera for recording picture images and data images on a film comprising: (a) first recording means for recording a picture image on a selected part of the film; (b) second recording means for recording a data image on a portion of the film; (c) manually operable trigger means; and (d) control means responsive to said trigger means for controlling said first and said second recording means, said control means being arranged to cause operation of said first recording means and to prevent operation of said second recording means while said trigger means is operated.
