No. 10/940,592 filed Sep. 13, 2004, from which priority is claimed under all applicable sections of Title 35 of the United States Code including, but not limited to, Sections 121 and 365(c), and the entire contents of which are incorporated herein by reference. 
     
    
     BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates generally to electronic devices, particularly portable electronic devices and more specifically to portable electronic devices having multiple body elements configurable to predetermined fixed orientations each of which define a respective different operative position. 
         [0004]    2. Description of Related Art 
         [0005]    The demand by users and the purchasing public that portable electronic devices, particularly mobile telephone devices, become increasing smaller and lighter while at the same time providing an increasing number of different functions in addition to the basic telephone communication functions places a premium on available surface space for the user interfaces necessary to carryout the intended functions and operations of the associated features. In addition, there is also a demand for larger size screens for displaying images, for example, taken with a camera built into the mobile telephone or for displaying received images such as streaming video. This demand has required the manufacturer of such devices to design and develop innovative device enclosures capable of reconfiguration from one operative position to another to provide the necessary user interface to operate the device and to accommodate larger size screens. One such mobile telephone device enclosure is the “flip” phone wherein the cover of the device is hinged to a main body element which carries a user interface relative to usage and the cover is “flipped” to open the device to make the user interface assessable to the user. The inside surface of the cover carries a screen to display alphanumeric characters, graphics, images and other representations common to such mobile telephone devices and which are commonly known in the trade and by the consuming public. The “flip” phone enclosure configuration provides one method to expand the user interface surface and provide a larger screen display area while maintaining a relatively smaller size device enclosure compared to other mobile telephone devices wherein the user interface and the screen share a common surface area. 
         [0006]    Another mobile telephone device enclosure as illustrated, for example, in  FIGS. 1A-1C  is the “slide” phone generally designated  10  wherein the cover  12  overlays a main body element  14  and is arranged for sliding engagement with the main body element  14 . The cover  12  carries a screen  16  and may include keys  18  to carry out various intended functions of the device when the cover  12  is in its overlying operative position as shown in  FIG. 1A . The device is configured to a second operative position when the cover  12  is slid by a user in the direction shown by arrow  20  to expose a surface  22  of the main body element  14  as shown in  FIG. 1B  wherein the surface  22  carries a user interface  24  which may be an arrangement of keys  26  in a desired pattern to carry out the intended function such as inputting a telephone number or entry of alphanumeric characters to the device in a well known manner. The device is returned to its closed operative position by sliding the cover  12  in the direction shown by the arrow  21 . Although such “slide” phones provide ease of usage in changing from one operative position to another operative position, the increase in effective user interface area provided by “slide” phones is not as effective as “flip” phones because of the limited movement of the cover  12  with respect to the main body element  14 . As schematically illustrated in  FIG. 1C , an overlap of the cover  12  and main body element  14  represented by the length  28  is typically a 50 percent overlap and results in a hidden area  30  between the cover  12  and main body element  14  to maintain rigidity of the “slide” phone in its extended open position and thus the hidden area  30  of the main body element surface  22  is not available for usage as a user interface or for any other function. 
         [0007]    What is needed therefore is a portable electronic device wherein one body element is arranged to move relative to another body element from an overlapping closed operative position to a non-over lapping operative position to maximize the surface area relative to usage of each body element. 
         [0008]    It is also desirable to provide a portable electronic device wherein one body element is arranged to move relative to another body element to maximize the surface area relative to usage of each body element for use as a user interface. 
         [0009]    It is also desirable to provide a portable electronic device wherein one body element is arranged for relative movement with respect to another body element to configure the body elements in a number of different predetermined fixed orientations each of which define a different operative position.
