Keyboard key processing unit, a keyboard for the processor design and construction of the processing unit KEYBOARD

摘要

The invention relates to a keyboard processing unit. Its use in various function keypads provides a technical effect of improving the reliability and extending the application field by eliminating the embedded processor. This result is achieved thanks to the fact that the key comprises: a key body; keyboard display buttons at the top of the housing for displaying images from a particular user to set a predetermined image processing unit with the possibility of rapid change of images, each particular image is uniquely associated with the function which is currently performing the given key; contact card that is installed under the keyboards display and is designed for connecting its findings to the appropriate stub Keyboards; cylinder with an electrically conductive layer, providing a circuit corresponding to the keyboard contacts when the key is pressed; an elastic member providing key return to its original position after it is pressed; wherein the key body is provided with structural members for mounting the cylinder with an electrically conductive layer and the elastic member and for fixing the assembled key in the keyboard. A keyboard with such keys also comprises: a memory for storing a plurality of predetermined images; a controller for controlling output of the selected image from the memory to display one of the keys and for generating a signal when a key is pressed according to the operation performed at the moment of the key; signal converter for converting signals from the controller to the signals transmitted to the processing unit, and inverse transform signal.
