19 авг 1800 г. - TYPEWRITER
Описание:
Description: a machine for writing in characters similar to those produced by printer's type by means of keyboard-operated types striking a ribbon to transfer ink or carbon impressions onto the paper.
History: The first manufactured typewriter appeared in 1870 and was the invention of Malling Hansen. It was called the Hansen Writing Ball and used part of a sphere studded with keys mounted over a piece of paper on the body of the machine.
Special Features: it has an array of keys, and each one causes a different single character to be produced on the paper, by means of a ribbon with dried ink struck against the paper by a type element similar to the sorts used in movable type letterpress printing.
Uses: It was used to produce printed characters on a piece of paper by typing individual keys.
Interaction/Exposure: Grandparents owned a typewriter and had the chance of playing with the keys but without the ribbon.
