Abstract
Interchangeable scanning drums of drum scanners that are seated at one side for scanning opaque or transparency image originals must be capable of being reliably and quickly connected to the rotatory drive of the scanner unit. Interchangeable drum structures facilitate the attachment of the image originals and allow an economic assembly of scanning drums that, preparatory to the job, can be loaded with image originals simultaneously with the scanning process. According to the Prior Art 874, it was hitherto necessary to design cost-intensive, actively supported work fixtures in order to achieve an adequately stable connection and a dependable, dynamic operation. The present invention avoids this disadvantage with a cost-beneficial design that makes use of centrifugal forces produced by the scanner rotation for the coupling of drum and drive motor flange in combination with toggle lever mechanisms.
