Abstract (en)
[origin: US4564187A] The sheet feed device (1) comprises several cassettes (13) on which the sheets (11) are stacked, a removal mechanism, associated with each of the supports, intended to remove a sheet from the cassette (13) and introduce it into the printer (2), and a selection mechanism intended to activate one of the removal mechanisms. This selection mechanism consists of a guide part (72) comprising several tracks (73 to 75) and a selection lever (56) made to engage with the top of guide part (72). When the platen (3) of the printer (2) turns in the direction opposite the direction of introduction of the paper, the selection lever (56) is driven in the same direction. After a rotation of a predetermined angle, greater than two turns of the platen, the direction of rotation is reversed. The lever (56) follows one of the tracks (73 to 75) to activate one of the removal control parts (76 to 78) and to start the removal and introduction process. This arrangement makes possible, on the one hand, an uncomplicated drive control comprising only a single reversal of the drive direction and, on the other hand, the possibility of rolling back the platen (3) to correct or complete a previously printed line, without thereby starting a new selection and removal cycle.
