Abstract: A turnstile entry gate comprising at least two, at equiangular distances on an arm carrier (5) mounted barrier arms (2-3), the arm carrier (5) being by way of a remote-controlled barrier device (6) arranged to permit or to prevent turning in at least one rotational direction. The arm carrier (5), or at least one of disks (7; 8) arranged near and connected thereto exhibits a magnetic strip (9) preferably extending circumferentially and adapted, by way of sensors, to indicate the position and the direction of movement of the turnstile. The barrier function of the device (6) is normally mechanically disconnected when one of the barrier arms (2-4) in the turnstile is in its home position, i.e. horizontally oriented, the sensor and electronic systems only checking that a passage has taken place and that, with the aid of e.g. a spring and/or hydraulics, the turnstile can assume its next home position.

Abstract: A turnstile provided with an electronic control unit having a photoelectric cell (8, 9) connected therewith, located downstream from the turnstile revolving member (3), in the user walking-through direction, in order to check if the user has actually walked through. Therefore, the turnstile has the ability to detect and issue a signal for, a simulated walking-through attempt performed by a user who actuates turnstile revolving member (3) without actually walking-through said turnstile, and it proves particularly effective for checking the arrival and the presence of personnel at the working posts.
