Abstract

Fiber positioning unit of SCARA type comprising an alpha (1,2,3) and a beta mechanism (4,5); the alpha mechanism successively comprising a motor (1), a driving shaft (2) and a rotatable shaft (3), the rotation of the rotatable shaft (3) being carried out by the alpha motor (1) via the driving shaft (2); the beta mechanism comprising a motor (4) and a fiber holding element (5) that may be rotated by the beta motor (4); both mechanisms being mechanically connected in a way to allow a rotation of the beta mechanism (4,5) by the rotatable shaft (3); the alpha mechanism (1,2,3) being furthermore adapted to be partially located within a focal plate (6), characterized by the fact that the alpha motor (1) is adapted to be located on one side of the focal plate (6) while the rotatable shaft (3) and the beta mechanism (4,5) are adapted to be located on the other side of the focal plate (6).
