     DETAILED DESCRIPTION OF THE INVENTION 
     The invention will be further described in conjunction with the drawings. 
     Referring to FIGS. 1-4, a staple remover of the present invention includes a frame  1 . A motor  2  is arranged at the front portion of the frame  1 . A gear assembly including a plurality of gears with different diameters is connected to the motor. A first gear  3  with a small diameter is driven by the motor  2 . The first gear is engaged to a second gear  4  with a larger diameter than the first gear  3 . A third gear  5  with a smaller diameter than the second gear  4  is fixed to the axle of the second gear  4  at the other side of the frame  1 . The third gear  5  is engaged to a fourth gear  6  with a larger diameter than the third gear  5 . At the same side of the fourth gear  6  is disposed a fifth gear  61  that shares the same axle as the fourth gear  5  and has a smaller diameter than fourth gear  5 . The fifth gear  61  is engaged to a sixth gear  7  with a larger diameter than the fifth gear  61 . 
     A driving wheel  8  that has the same diameter as the sixth gear  7  is fixed to the axle of the sixth gear  7 . Two connecting rods  11 ,  11 ′ are connected between the edge of the driving wheel  8 , the sixth gear  7  and a shaft  15 . A member  14  including a jaw  141  for removing a staple is mounted to the shaft  15 . At two sides of the frame  1  are provided two slide channels  16 . The shaft  15  is mounted in the channels  16  via two sleeves  21  such that the member  14  can move along the channels  16 . 
     Referring to FIG. 4 now, there is provided another shaft  20  at the front portion of the frame parallel to the shaft  15 . The shaft  20  is disposed within two inclined channels  22  parallel to the channels  16 . 
     Turning to FIGS. 3,  6   a , and  6   b , a transition member  13  is disposed at the bottom of the frame adjacent to the member for removing the staple, and has an inclined plane  131  providing a groove  18  that allows the jaw  141  of the member  14  to move along the inclined plane  131 . 
     Referring to FIG. 3, FIG. 7 a  and FIG. 7 b , adjacent to the transition member  13  on the frame is disposed a magazine  12  for containing the removed staple  19 . The magazine  12  at the upper portion provides a bevel plane  26  extended from the inclined plane  131  of the transition member  13 . Onto the bevel plane  26  is provided a slide plate  24  to which a driving block  27  is mounted. A spring  25  is arranged at the plane  26  and is connected to the slide plate  24 . 
     As shown in FIGS. 1,  3 ,  6   a , and  6   b , the member  14  may include a pair of blocks  23  at the two sides of the jaw to prevent the staple  19  from sliding off while operating. 
     Now turning to FIG. 5, a position-limit switch  9  is provided at the upper portion of the frame  1 . The position-limit switch  9  can contact a projection  17  disposed at the outer edge of the driving wheel  8 . 
     The operation of the staple remover according to the invention is now described. 
     When the jaw  141  of the member  14  is put under the staple  19  as shown in FIG. 6 a , a switch  10  disposed on the frame  1  is initiated to drive the motor  2  via the shaft  15 . The motor  2  drives the sixth gear  7  and the driving wheel  8  to rotate though the gear assembly. With the rotation of the gear  7  and the driving wheel  8 , the connecting rods  11 ,  11 ′ are driven to direct the member  14  to move along the inclined channels  16 ,  22 . At the same time, the removed staple with the jaw  141  moves along the groove  18  at the upper surface of the transition member  13  to reach the magazine  12 . The rear part of the member  14  pushes the driving block  27  on the slide plate  24  to move backwards so as to open the magazine. When the jaw moves above the magazine, the staple falls into the magazine by the weight. As shown in FIG. 8, the bottom  120  of the magazine  12  may be made from magnetic materials. At this time, the projection  17  contacts the switch  9  to stop the motor  2  to finish a cycle of removing the staple.
