A turnstile personnel access-control device () has one or more blocking arms () connected to a drive element () mounted on a carrier () such that the blocking arms are rotatable about a main axis or shaft (). The blocking arms () assume a blocking position and at least one free position in dependence upon the rotation of the drive element (). Each blocking arm () includes a flat component () that is mounted to rotate about a longitudinal axis () thereof in dependence upon the rotation of the drive element (). In the blocking position of the blocking arms (), one such flat component assumes a pre-defined angular position with respect to the vertical, whereas in the free position, this flat component () is rotated such that passage of a person is allowed.

Turnstile access-control device

A 2D barcode scanner () comprises a housing () having a reading window () and a digital camera () arranged in the housing () for detecting the area of the reading window () either directly or via a deflecting mirror arrangement (). At least one external light source () is provided for illuminating an area in front of the reading window () in the housing (), at the side of the reading window () that is facing away from the digital camera (). At least one external light source () is provided with an optical adapter () by which the light therefrom is distributed, such that the reflection paths are not illuminated at the inside of the reading window () back into the camera (), or are illuminated with a very low intensity. This avoids or significantly reduces the intensity of the light reflections that arise on the inside of the reading window () and are superimposed on the barcode that is to be read as very bright spots in the image of the digital camera ().
