    摘要: A method and a device for starting a machine, in particular, a printing press, using a sensor or sensor field which emits a start signal during the approach of a part of the body of a machine operator. According to the method, the machine is automatically started if the start signal appears twice consecutively and if the following additional conditions, automatically checked by a machine controller, are met: No start signal is present within a first predefined time period following the instant of the first appearance of the start signal in a predefined time interval, and the start signal reappears within a second predefined time period following the first predefined time period. The device includes a proximity- or touch-sensitive operating surface, which has a first partial surface having the function of a machine starter and second partial surface, which blocks the function of the first partial surface for a predefined period of time in response to proximity or contact.
