Abstract
774,426. Theatrical appliances. BRITISH BROADCASTING CORPORATION. July 27, 1955 [Oct. 16, 1954], No. 29838/54. Class 132(1). [Also in Group XX] The device which may be attached to a camera for movement therewith, comprises means for supporting,advancing and illuminating a script and a magnifying optical system adapted to produce an image of part of the script visible to a person in front of the camera looking substantially in the direction of the camera lens. The form shown is attached to a camera 10 by a bracket 11. The script 15 is fed from a roller 13 to a roller 14 by a motor of adjustable speed remotely controlled as by an electromagnetically releasable brake. The script is illuminated by lamps 16 and is viewed through an aperture 24 in a reflector 17. A magnified image formed by the lenses 18, 19 is rendered visible to the observer 22 by mirrors 20, 21. The front face of the latter, which is transparent, may be treated to increase reflection, the rear face to reduce it. A light shield 23 is provided. Alternatively, the mirror 21 may be replaced by an opaque mirror close to the lens axis. Specification 750,654 is referred to.
