Abstract: The invention relates to a magazine having a plurality of disk drawers which are mounted in disk-holding compartments and each of which holds a single disk (CD), all of the disk drawers being lockable in and releasable from the magazine by means of a single, common disk drawer locking mechanism and the magazine being capable of insertion into a machine. In order to create a magazine of straightforward, compact and economical design having as few components and being as simple to assemble as possible, the disk drawer locking mechanism is integral with the magazine. The disk drawer locking mechanism and the magazine are constructed as a one-piece injection molded unit in plastic and the disk drawer locking mechanism has a locking catch and a release tab which are joined to the magazine or an outer panel of the magazine by means of a common, elastic fulcrum bar and which pivot conjointly around the centre axis of the fulcrum bar thereby acting against its spring action.

Abstract: A device for compensating pitch errors in a worm gear consists of a stationarily mounted rotary worm-gear spindle (11) and a nut element (24) which is axially movable on said spindle and connected with an object to be translatorily moved. The object may be a support (14) for an image document, a slide or the like which is scanned in a scanner for enhancing data for electronic processing. The device is characterized in that the nut element (24) is composed of a plurality of resilient disks (17) accommodated in a transport sleeve (13) and each having a radial segment-shaped slot (18), in that the disks engage the threads (20) of the spindle by means of end faces (21) defined by the slots and in that the outer circumferential surfaces of the disks are fixedly connected with the transport sleeve. This allows the support (14) to be moved with great precision and the electronic data of the image document to be enhanced as correctly as possible.
