Abstract
A motor driven turnstile for providing cyclic access to a passage (16) to which a monitoring system or the like is allocated. The turnstile is controlled in such a way that, after a satisfactory monitoring result, each blocking arm (4) is first taken from the blocking position to a stopping position located at a small angle (alpha) from the blocking position, in which, after external pressure applied by the user, the arm is once again driven by the drive motor (6) and turned further until the next arm is in the blocking position.
