ABSTRACT:
A guide for directing a printing head parallel to a printing direction in a printing device, the said printing head being displaceable along two parallel, round guide rods which are maintained at a fixed distance from each other by sheet-metal clamps which extend transversely of the longitudinal direction of the rods and which are provided with bearing apertures in which the guide rods are clamped. The guide offers a comparatively high resistance against bending, so that a constant distance is maintained between printing head and record carrier.
