Abstract

The invention relates to a device for the removal and transfer of plate-shaped objects (CD) from a stack using a suction device being movable against a counter-force for generating a vacuum with a predetermined duration at a suction opening. To obtain a simple, compact and inexpensive design with safe, simple and gentle removal and transfer of plate-shaped objects such as ring disks or information carriers (compact disks, diskettes or floppy disks) in an automated environment, the device has two U-shaped hollow elements in a concentric arrangement that are on the one hand slideable towards and into one another with their open ends and on the other hand are substantially airtightly sealed in their movement range in relation to one another to the extent that when a vacuum is generated a leak flow of predetermined size and course is achievable, and hence also the vacuum duration that is predetermined for the removal of the object. Furthermore, a sensor device having a sensor, scanning marks and receiving device provided with two pivot-in holding elements for a plate-shaped object (CD) picked up by the suction device from the top of a stack are also provided.
