A rectangular connecting plate  25  has one end hingedly secured to the bottom edge  293 . The other end of the connecting plate  25  is connected to the back of the main support body  21 . The support leg  29  further comprises a curved member  292  on a center of a top edge, and a transverse ridge  291  on one end of the curved member  292 . The curved member  292  is shaped to complimentarily engage with an extending closed, rectangular, flexible flange  27  of the main support member  26  when the holder  20  is closed in a storage position (see  FIG. 9 ). The ridge  291  is adapted to insert in one of a plurality of parallel grooves  261  on the back of the main support member  26 . The ridge  291  can be retained by any one of the grooves  261  means that the electronic processing device  60  on the main support member  26  can be disposed in different angles with respect to the main support body  21  (i.e., different tilt angles). This arrangement enables a user to comfortably view the electronic processing device  60  in an optimum tilt angle. 
         [0030]    A rectangular rigid plate  28  is fixedly provided on a lower portion of the main support member  26  just between the grooves  261  and the bottom edge of the main support member  26 . The connecting plate  25  is adapted to rest upon the rigid plate  28  when the holder  20  is closed. Moreover, a closed elastic strap  23  may be used to wrap around the front portions of the main support body  21  and the main support member  26  in the closed position of the holder  20  (see  FIGS. 8 and 9 ). The provision of the elastic strap  23  can ensure the holder  20  and the device(s) (e.g., electronic input device  50  and/or electronic processing device  60 ) being retained in a protected state. 
         [0031]    Referring to  FIGS. 10 and 11 , a holder  30  for holding portable electronic devices in accordance with a third preferred embodiment of the invention is shown.

         [0034]    The holder  40  comprises a main support body  41 , a main support member  46 , and a support leg  49  as discussed in detail below. The support leg  49  is a rod-like member. A pivot pin  47  is provided on a back of the main support member  46 . A gear  471 , as one portion of a ratchet, is provided on the periphery of the pivot pin  47 . the support leg  49  comprises an annular hole  491  at a top end, the hole  491  being put on the gear  471 , a pawl  492  provided on the inner surface of the hole  491 , a lever  494  distal the pawl  492 , and an elastic member (e.g., helical spring)  493  biased between the lever  494  and the back of the pawl  492 . The front of the pawl  942  is formed with a plurality of teeth which are adapted to engage with the teeth of the gear  471 . A pivoting operation (as indicated by the upper arrow) of the lever  494  may compress the elastic member  493  to push the pawl  492  to pivotably move the gear  471 . As such, an angle of the support leg  49  with respect to the main support member  46  is changed. A reverse pivoting operation (as indicated by the lower arrow) will return the lever  494  to its original position with the engagement of the pawl  492  and the gear  471  remained unchanged. The above two steps can be performed repeatedly until a desire tilt angle of the support leg  49  with respect to the main support member  46  is obtained. Further, the bottom end of the support leg  49  is rested upon a planar surface (e.g., desk top). This arrangement enables a user to comfortably view the electronic processing device  60  in an optimum tilt angle. 
         [0035]    Referring to  FIG. 15 , the electronic processing device  60  may be alternatively rested upon the tilted flange  17  and the electronic input device  50  may be retained by the flange  12  in another configuration of use. 
         [0036]    While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
