Magnetic head assembly adjustable relative to roll, pitch and azimuth

摘要

A magnetic card transport system for use with an electronic typewriter includes a magnetic head assembly mountable on a bridge frame having a lead screw and a guide shaft mounted thereon. The magnetic head assembly includes a magnetic head attached to a head support. The head support is connected by leaf springs to a thread receiving structure having threads and adjacent guideways formed along an axis transverse to the longitudinal axis of the magnetic head. A clamp member is attached to the head support for engaging the threads against the lead screw and the guideways against the guide shaft whereby the magnetic head is automatically aligned relative to the lead screw and the guide shaft. The magnetic head is adjustable relative to the head support about the roll, pitch and skew or azimuth axes. The leaf spring attachment between the head support and the thread receiving structure permits resistive movement of the magnetic head relative to the lead screw and guideway.
