Abstract

1. Letter perforator comprising a perforator body (1) including an insert slot (5) and two perforator dies (3, 3') which are under the influence of a return spring (4, 4') and initially disposed perpendicularly to the insert slot (5) and guided in perforator-die guides, and which are operatable by a lever mechanism (2) acting on their rearward face surfaces whereby the lever mechanism comprises an operating member which is tiltable around a mounting pin aligned between the two perforator-die guides at the perforator body perpendicular to the plane formed by the perforator-die guides, characterised in that the lever mechanism comprises a single operating lever (2), constructed to be a two-armed lever, one arm of which displaces one perforator die and the other arm of which displaces the other perforator die (3, 3').
