Abstract
Receiver for rotating lasers used for guiding machines (for example public works machines), which comprises a receiver assembly proper (6) disposed on a support (9) enabling it to be fastened on the machine, a cell consisting essentially of plates (7) carrying photodiodes (8) and disposed around a fixed shaft in such a manner as to form a pillar enabling the passage of the beam to be detected over 360.degree., the assembly being protected by a peripheral shell (28) capped by a protective hood (27). The photodiode (8) plates (7) are three in number and are disposed vertically around a central support shaft to form between them an angle of 60.degree. to one another, the mounting being effected in such a manner that they are detachable and their fastening being achieved with the aid of damping members disposed at each end of the plate support shaft (7) and around the latter.
