Abstract
Abstract Code bars having first and second opposite edges with coded projections, are located between spring-biassed interposers and storing slides. When a key releases a selected first interposer, it engages corresponding first code projections of corresponding code bars and displaces the same so that storing members are displaced in accordance with the second coded projections. A typing operation is carried out under the control of the storing members, while the first selected interposer is driven back to its position of rest, and out of the locking means, so that a second selected interposer, whose key was operated during the printing operation, and which was blocked in a waiting position by the locking means, can enter the locking means and cause another printing operation.
