Abstract
In a device for converting into video signals the light signals from desired sections of a flat object such as a slide or a photographic print using a CCD-sensor (32), an optical system is provided which includes a lens unit (35) with a constant focal length. The optical system comprises at least two elements which are adjustable along the optical axis (30) and whose positions determine the image and the object distances for the imaging of the section of the object on the CCD-sensor (32). The two adjustable elements are connected by a gear mechanism (24) such that when the image and object distances are adjusted by the gear mechanism the lens unit (35) images the section of the object sharply on the CCD-sensor (32).
