OPERATING DEVICE WITH FOCUSSING OPERATING ELEMENT

摘要

The position of an operating element of an operating device should be able to be detected more accurately. For this purpose, an operating device with a base element (1), a transceiver device (2), which is fixedly arranged on the base element (1), for emitting and receiving light, a control element (6) which relative to the base element (1) between a first extreme position (10) and a second extreme position (11) is movable, and an optical element (8) which is fixedly arranged on the operating element (6), provided for deflecting the light (7) of the transceiver device (2) , By means of the optical element (8), the light (7) of the transceiver device (2) can be focused substantially in the direction of a receiving part (4) of the transceiver device (2). An evaluation device of the operating device is designed for evaluating a signal of the receiving part (4) such that an intensity of the received light (7) represented by the signal has a position of the operating element (6) in a region from the first extreme position (10 ) is assigned to the second extreme position (11).
