Description

overlapping contour and rotatable bearing block 1 is hinged, touches with his b 11 d i

is hinged to the bearing block 1, touches the free end of the value transmitter 11, which has a control flank 12 with individual steps, the boundary surfaces of which are concentric to the axis of rotation of the value transmitter. The element 8 is scanned by a pawl 13 resiliently mounted on the feeler lever 4. If a coin is now thrown into the time control device, a disc which adjusts the control time intervals and which is not shown for the sake of clarity, corresponds to the coin value-dependent angular rotation Valuator 11 rotated by a certain angular amount via the lever 14 and lifted the end of the element 8 from its rest position to one of the steps adjacent to it. This has the consequence that the EIementS is deflected, the pawl 13 is brought out of engagement with the stop IS holding the feeler lever 4 in its rest position and the feeler lever 4 is pivoted by the spring force of the tensioned spring 16 until the pawl 13 against that of the Abuts 10 which is not covered by the contour of Element_8.
