ABSTRACT:
In a printing device, including a drive means such as a stepping means and a driven shaft for advancing a form, a form aligning mechanism comprises a generally cylindrical hollow knob mounted concentrically with the driven shaft by a mounting means which converts a force of sufficient magnitude applied in almost any direction to the generally cylindrical hollow knob into a longitudinal displacement of the driven shaft so as to disengage the driven shaft from the drive means, thereby permitting fine adjustment of the vertical position of the form in the printing device.
