<p>A drinks machine (1) having a code reader device (8), which is designed to read an optically readable code (7) and having a sensor stage (16) for the opto-electronic capture of the code (7) during an exposure period and having an exposure control stage (20) for stipulating a value for the exposure period for the sensor stage (16), and having a bar code recognition stage (22) which is designed to check whether the captured code (7) is recognized, is developed by virtue of the bar code recognition stage (22) being designed to communicate a recognition error to the exposure control stage (20), and by virtue of the exposure control stage (20) being designed to alter the exposure period if a recognition error occurs during reading of the code. The invention also relates to a method for operating the drinks machine (1).</p> |
