Simulation des Durchganges verhinderndes Drehkreuz

摘要

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.
