Television image recording apparatus |
摘要 |
In a device that photographs a television screen a plurality of lenses are adjacently arranged on exchangeable lens supports. In order to achieve a higher image frequency and in order to avoid operating errors during the positioning of the lenses, the disclosure provides that the lens supports carrying the lenses are positioned in the image recording apparatus in a waiting position, and are selectively shifted by means of individual drives into the active position; a television monitor is moved into the correct distance relative to the selected lens support via an additional positioning drive.
