A writing apparatus provided with a character array positionable along at least one coordinate axis for character selection characterized by the selector mechanism comprising a support shaft; a first front cam mounted rotatably on said shaft and with the possibility of sliding axially thereon; a second front cam mounted on said shaft and kept essentially stationary with respect to it, together with said first front cam, forming a pair of front cams, so that one of the cams of said pair has a cam face or front that includes high and low parts of delay or permanence alternating in an angular sense and facing the other cam of said pair, and the distance between both high and low parts of permanence is dimensionally related to an increase between the locations of characters in the character array, said other cam having a follower part which is applied to the camming face of the first of said cams; means that can be put into operation selectively to rotate said first cam in a sufficient increment at least to put said high and low parts of permanence in cooperative contact of alternate application with said follower part of said pair; and means that functionally connect said first cam to the character matrix, to provide an axial movement that places the character matrix in position along its coordinate axis.
