Limited-Function Keyboard for Industrial Displays

       This article describes a limited-function keyboard that
fastens to the front bezel of an industrial computer display in place
of the original cathode ray tube (CRT) filter.

      The layout of the keyboard is shown in Fig. 1.  The keys
consist of thirty-six function keys, including six with
user-selectable legends F31 - F36; a numeric keypad; nine cursor
control keys indicated as the arrows, Home, End, Page Up, Page Down
and Back Space; plus Insert, Delete, Esc (escape), Ctrl, Alt and
Enter Keys.  Mounted in the center area, corresponding to the CRT
opening in the bezel, is a contrast-enhancing anti-glare glass panel.

      Fig. 2 is an exploded perspective view showing the mounting of
the limited function keyboard on the industrial computer CRT display.
 It is attached to the front surface via screws that attach to the
mounting holes originally intended for mounting a CRT filter.  The
keys are arranged such that they cover the bezel areas to the left,
right and bottom of the CRT.  The general locations of these key
groupings are shown.  The contrast-enhancing anti-glare glass panel
restores the visual enhancement originally provided by the CRT
filter.
