Abstract:
1. A supply unit for an activatable and deactivatable electronic apparatus, that can be activated and deactivated, which supply unit has a mains adapter, wherein the supply unit has a first voltage regulator and a voltage source which are connected at the input side with the direct voltage output of the mains adapter, characterized in that the supply unit has a logic module which is supplied by the voltage source with a suitable auxiliary directed voltage; that the first voltage regulator has an enable input that is connected with the output of the logic module and can be activated or, respectively, deactivated as controlled by the latter, wherein a switching contact pair is provided whose contacts are connected with one another to switch over the logic module; that a first contact of the switching contact pair is connected to the auxiliary direct voltage of the logic module and a second contact of the switching contact pair is connected on the one hand to an input of the logic module and on the other hand via the control output of the supply unit to an input of a microcomputer of a control unit; that, in the operating mode, the microcomputer is programmed by a program stored in a program memory in order to establish and evaluate the number and duration of the connection of the contact pair, wherein as a result an input of information is made based on a user input into the apparatus or a switching between states of the apparatus, wherein depending on the evaluation of the input in the microcomputer a digital signal is emitted at a control output to switch from the operating mode into a standby mode; and that a second input of the logic module is connected to the control output via a control input of the supply unit.
