Title: Auxiliary unit for electric typewriters - can separate data storage from typewriter itself giving substantial reduction in cost
Inventor: LAU MANFRED
IPC: B41J23/32
Filed: 1973-06-20
Abstract: Between the key lever and the action of the actual image carrier a small coil is situated. If the key is pressed, the inside core of the coil is moved to transfer the movement of the key to the action lever. This movement in the coil closes a contact, and current is fed into a code-translator. Each key has its own code. This code is fed into a data store which may consist of a magnetic tape. When typing is finished, the magnetic tape can be taken out and stored a away until needed again. Consequently automatic typewriters need no memory storage space, and device can be fitted on any type of electric typewriter.
