Magnetic Card Marking Device

The dictation unit has provision for marking a record media to indicate ends of letters or secretarial instructions, as well as to indicate the extent of progress during recording operations.

The unit in A has Mark button 1, depressed by the operator each time a mark is desired on record media 12. The latter, with aperture 12a, is inserted in the unit for engagement by pin 13 on band 14 rotated by a drive capstan not shown. Band 14, in turn, drives idler capstan 15 and through gears 16, 17, and 18 rotates lead screw 19 to drive magnetic head 20 and cam member 9. Also driven concurrently through cable 21 is scan assembly 10 with scan lever 22. Assembly 10 carries marking element 23 that can be a pencil, chemical ink or other marking media. To mark media 12, the operator depresses button 1 having leaf spring 2 that engages interposer 4 releasing it from bracket 3. Interposer 4 is connected with bell crank 8 that follows cam 9. This turns one revolution for each complete revolution of media 12 on capstan 15. Marking occurs when member 8 drops in the low dwell of cam 9, swings counterclockwise on shaft 11 due to pressure exerted by spring 5 in the direction indicated by arrow A. This permits marker 23 to move downwardly against media 12 to mark it. The high point of cam 9 restores element 8 and through extension 8a moves interposer 4 to the left to the restored condition on bracket 3.

The unit in B provides a mark on each revolution of the media to indicate progress of recording and a...
