Abstract

To provide simultaneous typing and a magnetic indicating of a typed character, the upper portion of the face of each type slug 11 is milled to produce projections 12 in a coded configuration representing that particular type character.

Simultaneous Typing And Magnetic Printing

To provide simultaneous typing and a magnetic indicating of a typed character, the upper portion of the face of each type slug 11 is milled to produce projections 12 in a coded configuration representing that particular type character.

The typing and printing are performed on a card 14 having spaced magnetizable stripes 15, which projections 12 engage when a key is actuated. Upon actuation, the type slug 11 is positioned adjacent a permanent magnet 16 which sends flux through the type slug head and its coded projections and then through the magnetic stripe 15 which is disposed at the printing station.

The magnetic circuit is completed through a steel insert 17 in the platen 18 and an armature 19 adjacent the other end of magnet 16.

The flux passing from the ends of coded projections 12 thus produces a corresponding magnetic pattern on magnetic stripe 15 so that this pattern may be subsequently magnetically sensed to determine the type character.

The tip of armature 19 is so spaced from stripe 15 that the flux passing through stripe 15 between armature 19 and insert 17 does not effect the magnetic pattern.
