Sheet feed device for a printer or typewriter
Abstract
Abstract The sheet feed device (1) comprises several cassettes (13) on which the sheets 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 (55) intended to activate one of the removal mechanisms. The mechanisms for removal and selection (55) are driven by the platen (3) of the printer (2). The selection mechanism (55) makes use of the position occupied by the mobile carriage (4). The latter carries a drive part (61) that can work with a set of selection levers (56). These levers (56) are equal in number to the removal mechanism. Depending on the position of the carriage during selection, one or the other of the levers (56) is put into active position and moved by a drive wheel (65) to activate a removal control element (76) and to start the removal and introduction processes. The device has the advantage that the platen (3 ) is driven in only one direction during a complete cycle of selection, removal and introduction of a sheet in the printer.
