Abstract: Marking apparatus is provided having a reciprocable carrier assembly composed of two parts. One part comprises a motor driven reciprocable carrier, while the other part comprises a movable carrier member which is pivotally supported at one end of the reciprocable carrier. The movable carrier member supports an inking roller and a printing roller and is mechanically coupled to the motor so as to cause the movable carrier member to be positioned, in the course of a first cycle of reciprocation by the reciprocable carrier, such that the inking roller is moved across the entire extent of an impression stamp supported and positioned on a fixed plate, and in the course of a second cycle of reciprocation by the reciprocable carrier, such that the pressure roller is rolled across a document which has been positioned over the stamp between the two cycles of reciprocation. The rolling action of the pressure roller causes the document to be pressed against the stamp to effect the desired marking.
