Abstract
The device includes a single external control member including a pusher (10) whose head (11) and tube (13) are assembled on either side of a control button (15) which can manoeuvre a rack (35). The driving arm (49) of a lever, (45) pivoted at one end of the rack (35), abuts on the pusher tube (13) and the driven arm (51) can be positioned opposite a determined corrector (9a) by rotation of the lever (45). One or several applications of pressure on the pusher (10) activate said corrector (9a) by rotation of the lever.
