Abstract
Abstract In order to control or identify an authorization of access, use is made of a control station which has two different read-write systems. The first unit is designed in particular for remote control of active date carriers comprising a microcomputer. The second read-write system is designed for the control of passive data carriers, on which the data are stored in a magnetic or optical form. Preferably both read-write systems are provided with parallel outputs, to which a switching system is connected, which passes to the peripheral systems the output signals produced by means of the desired data carrier.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A control station for the examination of data stored in data carriers, comprising a first control device comprising a transmitter/receiver unit for a distant control of an approached data carrier also having a transmitter/receiver unit, and a second control device comprising an insert slot for a control of a data carrier to be inserted into the slot, the first and second control deices having parallel outputs connected to a conversion unit, and at least one peripheral device being connected to the conversion unit and controlled by the output signal generated by the data carrier.
Claim 2
Dependent Claim
94 words
A control station for the examination of data stored in data carriers, comprising a first control device comprising a transmitter/receiver unit for a distant control of an approached data carrier also having a transmitter/receiver unit, and a second control device comprising an insert slot for a control of a data carrier to be inserted into the slot, the first and second control deices having parallel outputs connected to a conversion unit, and at least one peripheral device being connected to the conversion unit and controlled by the output signal generated by the data carrier.
Claim 3
Dependent Claim
50 words
A control station according to claim 1, wherein a peripheral device is formed by a multi-color signal lamp arranged in the housing to display the control result, the transmitter/receiver unit of the first control device and the lamps of the signal being covered by a common covering of frosted glass.
Claim 4
Dependent Claim
35 words
A control station according to claim 1, wherein each data carrier equipped with a transmitter/receiver unit comprises a ready circuit which can be activated by means of a signal emitted by the first control device.

Claim 9
Dependent Claim
20 words
A control station according to claim 6 further comprising a limiting blind arranged at a distance to the transmitter/receiver unit.
Claim 10
Dependent Claim
25 words
A control station according to claim 1, wherein the second control device comprises a write-read head and a print head subsequent to the insert slot.
Claim 11
Dependent Claim
17 words
A control station according to claim 1, wherein both control devices are arranged in a common housing.
Claim 12
Dependent Claim
59 words
A control station according to claim 4, wherein the carrier frequencies for the data transfer from the control station to the data carrier as well as from the data carrier to the control station are different, the transmitter/receiver unit of the control station comprising a transmission oscillator, and the transmitter/receiver unit of the data carrier comprising a frequency divider.
Claim 13
Dependent Claim
20 words
A control station according to claim 6, further comprising a limiting blind arranged at a distance to the transmitter/receiver unit.
