Abstract

496,835. Television receivers. GENERAL ELECTRIC CO., Ltd., and JESTY, L. C. Oct. 22, 1937, No. 28910. [Class 40 (iii)] The optical distance of an image of the reproduced pic. ture from the screen 2, on which the picture is formed, is so varied in dependence on the optical distance of the sheet 5, which is viewed, from the screen that the image is formed on the sheet in every position of the sheet in which it can be viewed. The sheet can be viewed either in the horizontal 5B or the vertical position 5A. The screen 2 is horizontal and a mirror 7, which is inclined at 45‹ to the horizontal, enables the sheet in the horizontal position to be viewed horizontally and, when the sheet is vertical, deflects the optical axis through a right-angle. According to a modification, the sheet has two vertical positions and two alternatively operative mirrors deflect the optical axis through a right-angle, Fig. 2 (not shown).
