摘要

The plotter has a base (30) that is attached to a contact surface (20), and a retaining arm (40) that is attached at the base. A laser (50) emits laser beam perpendicular to the contact surface and is fastened at a free end of the retaining arm. A writing device (60) is attached at the retaining arm, where a writing point (60A) of the writing device is arranged adjacent to the laser beam in a plane of the contact surface.
