A portable data collection terminal has an elongate housing with a hand grip conforming rear surface. A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys of the numerical keyboard are identified by indicia disposed on a template. The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template. As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal. The system includes terminals in the form of wireless transceivers in communication with base stations. |

DETAILED DESCRIPTION The objective of the present invention was, early on, to expand on the utility of relatively small, portable, hand-held data collection terminals.
The invention recognizes a need for greater versatility in hand-held data terminals, thereby improving indirectly an overall usefulness of a business system which uses a number of these data terminals as roaming data input and retrieval devices.
It is therefore an object of the invention to provide an improved compact data input and display device with increased functionality.
It is another object of the invention to arrange an alphanumeric keyboard for multi-orientational use.
Further in accordance herewith, it is an object of the invention to provide a pen-activated data input device which interactively may be prompted through display screen prompts.
Another object of the invention is to provide a robust data terminal having a display screen sized to permit operator input via pen strokes and having the capability to change to keyboard entries interchangeably with entry via pen-type signals.
Yet another object of the invention is a power management control function implemented through software controlled microprocessor functions, the power management function including selectively shutting the data terminal down without loss of current data interchange status states on an Input-Output bus (I/O Bus).
According to one aspect of the invention, it is consequently contemplated to increase the data input capacity of a portable data terminal with a touch sensitive liquid crystal display overlay.
The touch sensitive display overlay may function as a keyboard or as a provision for entering graphic data such as signatures.
Another keyboard may be a numerical keyboard or may be activated as a function keyboard to supplement a touch sensitive keyboard implemented as an overlay of a display screen.
In a particular embodiment in accordance with the invention, keys of the touch sensitive keyboard of the display screen of the portable data terminal may be selectively reorientable with respect to the data terminal
