DETAILED DESCRIPTION

(11) As shown in FIGS. 1 and 2, the reading unit according to the invention consists of a housing 10 which, as will be explained below, can be built into an access control barrier such as a turnstile, or simply be arranged with signaling devices in the access region. A reading module is arranged in the upper part of the housing 10. Below the reading module, a U-shaped insertion region 1 for data carriers 5, 5 is formed by an upper first wall 2 and a lower wall 2.

(12) In particular, it may be provided that the reading module has a window 3 with a bar code scanner 11 behind it arranged in the upper first wall 2, such that the bar code scanner 11 scans the insertion region 1 through the window 3. The upper wall 2 comprises a window 3, showed as shaded in FIG. 2, through which the bar code scanner 11 scans the insertion region.

(13) Multiple suitable bar code scanners are known, for instance the Zebra DS457 Imager, and they typically use camera systems with downstream evaluation logic, which scan a bar code and transmit its numerical content to an access system downstream. It should be pointed out explicitly, however, that in the framework of invention, this bar code scanner 11 can obviously be exchanged for any other suitable scanning technology, including, for instance, by an RFID reader. Accordingly, the term windows 3 must be understood abstractly; what is material is that the upper wall 2 of the insertion region 1 for the respectively selected scanning technology be transparent (for instance to infrared electromagnetic waves of the RFID reading module).

(14) The configuration of the reading unit according to the invention shown in FIGS. 1 and 2 is optimally suited for card-shaped data carriers 5, since it can be easily presented for reading the authorization, and the user would intuitively understand that they are expected to insert the data carrier 5 into the insertion region 1. This configuration corresponds to the first state of the reading unit.

(15) FIG. 4 shows that the lower wall 2 of the insertion region 1 is foldably attached to the housing 10 by means of a hinge 12. The arrow 6 marks the swinging movement of the lower wall 2, which is made possible by the hinge 12. If the lower wall 2 is now folded upward, the formerly U-shaped insertion region 1 is converted into an L-shaped insertion region 1 that is open towards the bottom. The reading unit according to the invention is now optimally configured to read data carriers 5 in the form of a wrist band, since the user can easily bring their arm into a position suitable for reading. FIGS. 3 and 5 show this position in an oblique view and in a schematic cross section. This configuration corresponds to the second state of the reading unit.

(16) Therefore, a device for checking access authorizations stored on data carriers 5, 5 can be provided, having a reading unit, arranged in the access region, for the data carrier 5, 5, which actuates signaling means and/or blocking means 4. The reading unit features a housing 10 with a U- or V-shaped insertion region 1 for the data carriers 5, 5, and wherein the U- or V-shaped insertion region 1 is formed in part by an upper first wall 2, in which a window 3 is arranged with a bar code scanner 11 behind it, which scans the insertion region 1 through the window. The second, lower wall 2 of the U-shaped insertion region 1 is attached to the housing 10 by means of a detachable or swiveling hinge 12, such that the U- or V-shaped insertion region 1 can be converted into an L-shaped insertion region 1 that is open towards the bottom by pivoting or removing the lower wall.

(17) It is also indicated here that above of the insertion region 1, a large-scale display 14 is arranged on the housing 10, such that usage instructions can be entered directly in the reading zone.

(18) Wrist bands as data carriers 5 for access control are commonly known, and they typically use either bar codes imprinted on the wrist band or RFID Inlays. Wrist bands are particularly favored for one-time events, since the wrist band can be attached to its owner with a single-use seal, this preventing a transfer to unauthorized third parties. Another application is swimming pools, where the wrist band is well-suited to attach the data carrier to the authorized person without risk of loss.

(19) FIG. 6 shows a schematic access control with a column 13 supporting an access blocking means 4. In this example, the blocking means 4, which may also be referred to as a blocking device or as an access barrier, is a flap arm that can be motorically moved from the Closed position to the Open position when the access system recognizes the authorization as valid.

(20) The person approaching in FIG. 6 carries a data carrier 5 in the form of a wrist band, and the reading unit according to the invention is configured with an L-shaped insertion region through the folding up of the lower wall 2 of the insertion region, that is, in the second state. It is clearly visible here that the reading unit according to the invention allows for a readable delivery of the data carrier 5 in wrist band format.

(21) FIG. 7 shows the same access control, wherein here the reading unit according to the invention is configured with the wall 2 folded down, that is, in the first state, in order to offer the user with a card-shaped data carrier 5 optimal ergonomics.

(22) The invention therefore provides a reading unit that may be adjusted for any respective application. This is particularly advantageous when the requirements of the data carriers 5, 5 may change in the short term. For instance, access control to a holiday resort may be configured in winter with a U-shaped scanning region for cards, and in the summer with an L-shaped scanning region.

(23) The reading unit shown in FIG. 8 features two proximity sensor 15 and 15 in addition to the bar code scanner 11. By way of a proximity sensor, for instance, a light scanner can be used, such as the Sick WL 11 photoelectric sensor. Such a light scanner sends out a light beam, which may be reflected by a person standing in the path of the beam, and which controls a switch output.

(24) The scanning range 16 of the first proximity sensor 15 seen in the IN direction of access is oriented before the insertion region 1 for the data carriers 5, 5. The scanning range 16 of the second proximity sensor 15 seen in the IN direction of access is oriented behind the insertion region 1 for the data carriers 5, 5.

(25) FIG. 9 shows the advantages of this configuration of the reading unit according to the invention in terms of access for people. The scanning beam 16 of the first proximity sensor 15, which is cast in the direction of access IN, detects that the person presenting a data carrier 5, 5 for reading to the insertion region 1 is correctly moving in the direction of access.

(26) If this person would be on the exit side OUT, the scanning beam 16 of the second proximity sensor 15 behind the insertion region 1 would detect this and report it to an evaluation logic, not shown here. The release of the blocking means 4 could then be prevented.

(27) The same applies when access for an entering person is blocked by another person. That situation too is detected.

(28) This embodiment according to the invention makes it further possible to release the blocking means 4 in the respective direction by assigning the reading of a data carrier 5, 5 by the reading module, in particular a bar code scanner 11 or, in case of RFID data, an RFID reader, to the direction of movement of the user. This release is then performed by the evaluation logic not shown here, which queries the reading module and the two proximity sensor 15 and 15 and correspondingly generates release commands for the blocking means 4.
