摘要： A velocity modulator device is provided for printer type supports driven by rotary members comprising at least one driving mechanism including a motor causing a rotary member to rotate by means of a resilient torsion bar, said mechanism having a mechanical resonance frequency F. In accordance with the invention, the velocity modulator device is characterized in that the motor is a low inertia direct current motor supplied by a periodic current of the frequency F, the intensity of the current being such as to periodically bring the velocity of the rotary member to zero, at the frequency F, without changing its direction the motion of said member, resulting from superposition of a rotary uniform driving motion and an oscillatory motion at the frequency F.
