摘要

Improved lectern for typewriters, characterized in that it is of the type that is constituted by a vertical surface provided on top of a document retention rod, also comprising an indicator strip that moves with respect to said surface under the action of a knob that moves over sets of pulleys to respective tractor cables linked to said terminal strip, part of said vertical surface forming a lower platform that acts essentially as a support for the typewriter, being articulated on the platform itself a lateral lever of drive that extends to the spacer of the machine being superimposed on a height adjustable stop that governs the displacement to spaces of said aforementioned terminal strip, and because the actuating lever is connected with interposition of a connecting rod to an articulated arm with the help of a spring on the control shaft that drives the tractor cables is tando topped by an articulated fork that attacks by one of its branches a pinion fixed to the aforesaid axis of the command causing the displacement of the cables that actuate the strip according to the space regulated by the travel stop for the actuating lever, while on the other branch the fork rubs in its recess on a static release cam that allows the free movement of the indicator bar under the action of the control, the latter being substantially provided with an articulated upper sector that rotates under the action of a radial handle .
