Description

sich ein Stapel St blattförmiger Aufzeichnungsträger befindet. Über dem Ablagefach M ist eine Bremsplatte Br so angeordnet, daß sich seine, der Transportbahn T zugewandte Seite oberhalb der Transportbahn befindet. An der Bremsplatte Br sind, mehrere Düsen angebracht, durch deren Saugöffnungen D die umgebende Luft unter der Bremsplatte Br abgesaugt wird. Zum Transport des auf der Transportbahn T befindlichen Aufzeichnungsträgers A T dienen mehrere Rollenpaare R, von denen hier der Einfachheit halber nur ein Rollenpaar dargestellt ist. Etwa eine Aufzeichnungsträgerlänge vor der Einmündung des Ablagefaches M befindet sich als Abtastorgan A eine Fühldüse, deren Düsenöffnung beim Vorbeigang eines Aufzeichnungsträgers A T von diesem verschlossen wird. Das dadurch gewonnene Signal dient zum Abschalten des Unterdrucks unter der Bremsplatte Br mittels eines Drei-Wege-Membran-Schalters V. Der unter der Bremsplatte Br wirkende Unterdruck bleibt so lange abgeschaltet, bis das einlaufende Blatt auf seinem Weg in das Ablagefach die Öffnung der Fühldüse wieder freigibt. Dadurch löst sich der vorangehende Aufzeichnungsträger schon vor dem Eintreffen· des nächsten Aufzeichnungsträgers von der Bremsplatte ab. Der nachfolgende Aufzeichnungsträger schießt mit der ihm von den Rollen des letztenthere is a stack St of sheet-shaped recording media. A brake plate Br is arranged above the storage compartment M in such a way that its side facing the transport path T is above the transport path. A plurality of nozzles are attached to the brake plate Br , through the suction openings D of which the surrounding air is sucked out under the brake plate Br . Several pairs of rollers R are used to transport the recording medium AT located on the transport path T , of which only one pair of rollers is shown here for the sake of simplicity. About one record carrier length in front of the opening of the storage compartment M is a sensing element A , the nozzle opening of which is closed by a recording carrier AT as it passes by. The signal obtained in this way is used to switch off the negative pressure under the brake plate Br by means of a three-way membrane switch V. The negative pressure acting under the brake plate Br remains switched off until the incoming sheet opens the sensor nozzle on its way into the storage compartment releases again. As a result, the previous recording medium is detached from the brake disk even before the arrival of the next recording medium. The following recording medium shoots with it from the rolls of the last one

Only when the negative pressure is switched off when a recording medium comes in again does the recording medium adhering to the brake plate Br fall into the storage compartment M.

The disadvantage of this known brake plate, which is provided with suction openings, is to be seen in the fact that it is arranged for the recording medium to slide along its underside through thin and high-speed inertia. and mechanical means applied to the brake plate are insufficiently sucked by negative pressure, characterized by ensuring that the recording media are protected.
