<p>A preconfigurable entry device for a data processing facility as for example a computer, consisting of two arrays of keys, one or several control panels, electronic circuitry and the electronic components belonging to them. The entry device comprises electronic preselecting means which can be controlled by aid of mechanical switching means on the control panels and which allow for an optimal adaptation of the keyboard to different fields of applications and which facilitate a touch driven, rhythmic operation of the keyboard considerably to the user using ten fingers during a working session. The entry device consists of a left and right part, whereby both parts comprise keys and mechanical switching means and electronic circuitry, both parts being mechanically independent from each other and therefore arbitrarily moveable relative to each other. The keys are made couplable to coding units, capable of creating code signals. First and second shift keys are coupled to switching devices. The switching devices are coupled accross control lines either directly to coding units or they are coupled to one or several preselecting means allowing for a selection of a multitude of additional coding units.</p> |
