Abstract: A positioning device for optical data storage which has an optical system for generating a polarized, parallel laser light beam and for receiving gated out reflected light beams for evaluation and a sensing head which is radially displaceable relative to a storage disk characterized by the optical system being contained in a rigid frame mechanically decoupled from the sensing head. The system includes a pivotably mounted deflection mirror which enables fine positioning. The sensing head will include an imaging system for focussing the laser beam onto the storage disk which is resiliently hinged to the sensing head so that it is deflectable in a vertical direction for readjustment of the focussing independent of radial motion of the sensing head.

Abstract: A document processing device is provided which is front accessible for use and service and is composed of a paper supply space for cross-perforated continuous-form paper webs, a printing mechanism including a paper feed device, platen and print head, a separator device for producing single documents and an output and/or deposit stacker for single documents. The paper feed device and the paper guidance elements proceeding along the paper web are arranged such that the paper supply space closable by means of a removable housing cover as well as the output and/or deposit stacker are accessible from the front side. The paper supply space and the printing mechanism are located in a lower cabinet rack part whereas the paper guidance elements and devices including the output and/or deposit stacker which follow downstream of the printing mechanism are located in an upper cabinet rack part pivotably secured to the lower cabinet rack part.

Abstract: In a document processing facility whose operation is initiated by user-associated authorization cards which can be plugged into a badge reader, a deposit stacker which is not accessible from the outside is provided below the output stacker. A document seating surface is provided in this output stacker, this document seating surface being movable by a drive device back and forth between a document output position and a deposit position, whereby, in the deposit position, an opening in the deposit stacker is exposed, the documents falling into the deposit stacker after being released by braking elements provided in the output stacker.

Abstract: A collecting stacker for collecting all documents of a user is provided in the printing mechanism preceding the output stacker, whereby a retention mechanism is provided at the output of the collecting stacker, this retention mechanism opening after the arrival of the last document with respect to the individual user and initiating further transport of all documents contained in the collecting stacker into the output stacker in common. Documents left in the output stacker are subsequently transported to a user inaccessible deposit stacker.

Abstract: A device for separating multi-layered strips of paper having carbon paper provided therebetween. The separating device cooperates with the transversely located perforations in the continuous strip to drive the continuous strip through the separating device. The continuous strip also has transversely extending serrations therein which are severed in the separating device so that the continuous strip is separated into individual sheets. Each station in the separating device has a pair of inlet rollers and a pair of outlet rollers with the outlet rollers being driven at a speed which is greater than the speed of the inlet rollers so that the continuous strip is effectively pulled so that the transversely extending serrations will become severed and the individual sheets will be collected at an outlet.
