Abstract
A transfer device to transport a film card from a film platform of a microfilm reading machine to a cassette and in the reverse direction has a transport device which has two mutually opposite rotary disks which are approachable towards each other like the jaws of tongs. This transport device is capable of moving towards the film card, so that the film card passes between the disks. One of the disks is driven so that the film card is transported as soon as it passes between the disks. Due to the arrangement of a pair of disks, the transport device is extremely flat so that it can withdraw a film card from a cassette without the need for it to be slid into the induction region of the transport device by means of, for example, a ram.
