Automated teller machine and method for detecting tampering with the automated teller machine
An automated teller machine comprises at least one RGB light source, which is disposed on an operating side of the automated teller machine and emits an RGB mixed light, and an optical RGB sensor for sensing the RGB mixed light emitted by the RGB light source, the optical RGB sensor being disposed at a distance from the RGB light source. Furthermore, the automated teller machine comprises a control unit, which is designed such that the control unit detects tampering with the automated teller machine on the basis of the emitted and the sensed RGB mixed light.
1. An automated teller machine comprising:
an output compartment with an output region for outputting notes of value;
a closure element moveable between an open position and a closed position and closing the output compartment when in the closed position;
wherein the output region is delimited in part by a first delimiting wall and a second delimiting wall, the first delimiting wall and the second delimiting wall facing each other on opposite sides of the output region;
wherein the output region which is further delimited by the closure element when the closure element is in the closed position;
an arrangement for monitoring the output region with at least one sensor unit arranged and configured to detect a cash trapping element arranged in the output region wherein the at least one sensor unit includes:
an optical element positioned in the first delimiting wall and having a strip shape,
a plurality of light receivers positioned in the second delimiting wall, and
a plurality of light emitters positioned behind the optical element, wherein light emitted by the plurality of light emitters is scattered by the optical element and radiated uniformly outward, wherein the light emitted by the plurality of light emitters is receivable by the plurality of light receivers, wherein the at least one sensor unit is configured to emit a detection signal in response to the plurality of light receivers not receiving the light emitted by the plurality of light emitters; and
a control unit configured to receive the detection signal and to detect a tampering proceeding in response to receiving the detection signal.
2. The ATM of claim 1 wherein each of the plurality of light emitters comprise red-green-blue (RGB) light sources.
3. The ATM of claim 1 wherein the plurality of light receivers are recessed from a front edge of the output region five to ten millimeters.
4. The ATM of claim 1 wherein the output region is further delimited in part by a third delimiting wall and a fourth delimiting wall, the third delimiting wall and the fourth delimiting wall facing each other on opposite sides of the output region, and the optical element extends fully between the third delimiting wall and the fourth delimiting wall.
