ABSTRACT:
A typewriter comprises a carriage (1) sliding parallel to a platen (3). The typing device (2) operates in a printing zone which is displaced along this platen (3).
The casing (7) of the machine is open above the platen (3) and has a transparent anti-noise hood (10) covering its opening (8).
In order to facilitate the reading of the last line of type across the hood (10) which absorbs a part of the light, the typewriter is provided with means for illuminating the platen (3). These illumination means are constituted by electric bulbs (17) either carried by a transparent slide (14) housed in a U-shaped throat (12) or lie in the direction of the platen (3).
