Abstract
Abstract A manuscript in card, sheet, or strip form is moved across a table which is the object plane of a television camera. The camera is adjustably positioned above the table and the camera output is connected to a closed circuit system which includes one or more television picture tubes for showing an image of the manuscript. One picture tube is positioned in front of the speaker. Electrical controls are provided for adjusting the speed of the manuscript as it moved through the object plane. Adjustments are also available for focusing the television camera lens and for swinging the camera from one position to another to pick up information to be conveyed to the speaker.
