1. The device for reproducing sound tests is designed especially for the blind. It has a control panel with a plate. Above the plate, there are two perpendicular guides, a horizontal one and a vertical one, with a shifting position detector, connected through a connecting conductor to the data registration and processing system, equipped with a power switch, a decoder, a disk drive, a light control and sound processing sockets. It is characterised in that the sliding carriage with a rotary converter (4) is mounted on the horizontal guide (5). The slider (23) with the rotary converter (4) with an outrigger (19) is mounted on the vertical guide (25). The outrigger has cross-hairs (26) and a position detector (18) with a button (17). The rotary converters (4) on the carriage (2) and the slider (23) are connected through the position detector (18) to a known system of data registration and processing (40). |
