| 摘要 |
The invention relates to a passage control device for non-contacting data carriers, comprising an antenna unit (5) with a front wall (12) which extends along the direction of the passage and faces said passage and whose height corresponds to the varying heights at which the data carriers are worn. At least one antenna (13, 14) for transmitting data in the radio-frequency wave range is positioned on the wall. The device also comprises a turnstile gate (4) having a hinge pin (8) pointing downwards at an angle and stopping arms (10) which extend at an angle to the hinge pin (8). The front wall (12) of the antenna unit (5) extends beyond the turnstile (4) bearing and points downwards. The turnstile (4) is mounted in the forward part of the antenna unit (5), as seen in the direction of passage (15), and the section (17) of the front wall (12) extending beyond the turnstile bearing and downwards extends at an angle towards the rear. The front wall (12) of the antenna unit (5) is configured as an information surface (18) for optical information.
