Abstract

A document encoder is described, which is conceived as a compact desk set. In order to serve as a multi purpose unit and in spite of that exhibit a compact type of construction, the various printing devices (2, 4, 6, 7, 8) and print backings (41, 42; 47; 55; 64, 71) impacting the document from its front- and back side are arranged stationary in a chassis (1), while the printing process in direction of the lines is accomplished solely through conveying the document by means of a conveyor device. The print devices and the print backings are arranged so that they apply print to the front- and back sides of the document in a partially overlapping way. The document conveyor path (10) is U-shaped, whereby the input station (11) is located at one leg of the conveyor path (10), the printing devices (2, 4, 6, 7, 8) at the other leg (15). The printing mechanisms themselves are either type wheel printing mechanisms (3), stamping print mechanisms (4, 6) or needle print mechanisms (7, 8), according to the desired needs.
