Abstract

In an information input and output unit (10) for data processing equipment, including an input keyboard (14) and a tactile read-out panel (28) with a control keyboard (30) for tactile data display for the vision impaired, it is provided, for making operation by vision-impaired persons easier, that the input keyboard (14), the control keyboard (30) and the tactile read-out panel (28) are arranged in one plane, that the tactile read-out panel (28) with the control keyboard (30), as seen by the operator, is in front of the input keyboard (14) and that in front of the tactile read-out panel (28) is arranged a hand rest surface (102). Between the tactile read-out panel (28) and the control keyboard (30), finger guides (90) may be optionally provided to make the orientation easier. Parallel to the output lines (56,58) of the read-out panel (28) are formed receiving grooves for receiving replaceable information strips (70) which show heading information in the form of Braille characters (74,78 ). The input keyboard (14) is inserted removably in a receiving basin (38) of a case containing the read-out panel (28') and the control keyboard (30).
