Abstract A system is disclosed in which a keyboard operated device such as a typewriter is simulated for training purposes by providing a keyboard on which a prearranged sequence of alphanumeric characters are to be typed. Information relating to the prearranged sequence is stored on a piece of paper tape in a paper tape reader and is also presented on a sheet of paper inserted in the device. A covering means having a window therein is employed to cover the typed material. As the correct sequence is typed on the keyboard, the window advances incrementally one space at a time after a comparison is made between the information stored on the paper tape and the typed character. If a match is not made therebetween, the keyboard is inhibited so that the student cannot proceed further. When the window reaches the end of the line, the covering means is reset to recover the typed line and the paper upon which the alphanumeric information is present is advanced so that the line previously incrementally uncovered is moved out of the field of the covering means.

Total Claims: 4
Claim 1
Independent Claim
159 words
A device for simulating the operation of a machine which produces a display, said device including: first means for holding a prearranged multi-character display in a position; second means for covering said prearranged display; third means for mounting said first and second means with said covering means covering said position; said third means being responsive to an advance signal for producing a predetermined relative movement between said first and second means to selectively uncover a predetermined portion of said position; said predetermined portion being representative of a single character of said multi-character display a multi-key keyboard having means for providing an information signal in response to one of said keys being depressed said signal being indicative of which of said keys is depressed; fourth means for storing and presenting a stored signal indicative of a next key to be depressed; and fifth means responsive to correspondence between said information signal and said stored signal for providing said advance signal.
