Abstract:
A sheet deposition device for the selective depositing of printed sheets onto a plurality of superimposed supports, wherein each support is provided with its own drive means for moving said support up and down between a deposition position where sheets can be delivered to that support and a parking position in which sheet deposition is not possible, wherein each support is provided with detection means for detecting an obstacle disposed in the space therebelow, said detection means delivering a first detection signal when the distance between the support provided with said detection means and an obstacle disposed directly therebelow is greater than a predetermined amount and delivering a second detection signal when said distance is equal to said predetermined amount, wherein the sheet deposition device includes a control device which, in response to the reception of a first detection signal makes the drive means capable of activation for moving the supports towards one another between which are situated the detection means delivering the first detection signal and which deactivate the drive means in response to the reception of a second detection signal.
