摘要： A device for feeding of individual sheets to a plate (4) of an office machine, in particular of a matrix printer (1), is provided with several storage bins (5, 6). In each case a separating roller (7, 8) is coordinated to the storage bins (5, 6) and the separating roller (7, 8) is connected to a drive motor (9) via a gear train. In order to create a reliably operating storage bin selection, which can be employed for larger distances and for larger-volume storage bins, it is disclosed that the drive motor (9) can be left-hand or right-hand rotatably controlled, that the drive motor pinion (10) engages a first gear wheel (11), that an eccentrically supported cam (12) is carried by the first gear wheel (11), that the cam (12) engages into a switching rocker (13), and that at least a second gear wheel (15) is rotatably supported at the switching rocker (13) supported around a horizontal axle (14), where the second gear wheel ( 15) is tilted, depending on the rotary direction of the drive motor (9), into engagement with the respective gear wheel (16, 17) of one of the separating rollers (7, 8).
