Flexible Layout Price Look Up Keyboard Display

       Disclosed is a system for a Price Look-Up (PLU) Keyboard
Display Unit.  A conventional PLU has two displays.  One is for the
operator, and the other is for the customer.  These two displays are
usually fixedly mounted.  The Flexible Layout PLU Keyboard Display
unit disclosed herein has one display on the keyboard unit, and one
separate display.  The display on the keyboard has two-way usage,
that is, one is for the operator and the other one is for the
customer.

      High flexibility is required for the PLU Keyboard Unit in order
to respond to various requirements of the end user.  Therefore, the
display on the keyboard has two-way usage.  When this display is in
the position shown in Fig. 1, it is for observation by the operator
and it displays data from top to bottom.  When this display is turned
over, as shown in Fig. 2, it is for observation by the customer and
it displays data upside-down.

      Microcodes or hardware circuits respond to the position of the
display to convert between the up-right image and the upside-down
image.  This idea can be applied to all keyboards that have a display
unit such as the PLU Keyboard Display.  It finds usage in banks,
public offices, hospitals, etc.
