BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a line-arranging mechanism.  
         [0003]     2. Description of the Related Art  
         [0004]     One type of a line-arranging mechanism is applied to a fishing pole. Because the diameter of fishing line is very fine, regularity in the arrangement thereof does not affect the volume of the line-arranging mechanism. Another type of line-arranging mechanism is applied to household appliances. The regularity in the arrangement of a power line of a household appliance is of little concern. Referring to  FIG. 1 , a conventional line-arranging mechanism  10  demands that the power line be arranged regularly, thus, the conventional line-arranging mechanism  10  comprises a motor  11  to drive a reciprocator for arranging the power line. The conventional line-arranging mechanism  10  comprises a motor  11 , a lead screw  12 , a reciprocator  14  and a bearing (not shown). The motor drives the lead screw  12  and the reciprocator  14  for regularly arranging the power line.  
         [0005]     The conventional line-arranging mechanism  10  is complex and large, thus, the conventional line-arranging mechanism  10  is expensive. The volume of an electronic device has gradually decreased. If the line-arranging mechanism  10  is applied to an electronic device, the volume and cost are increased.  
       BRIEF SUMMARY OF INVENTION  
       [0006]     A detailed description is given in the following embodiments with reference to the accompanying drawings. A line-arranging mechanism comprises a cam, an axle connecting to the cam, a sliding element and a transmitting mechanism to drive the cam and the axle. The cam comprises an inclined surface and the sliding element to slide thereon.  
         [0007]     The transmitting mechanism comprises a sun gear, a planet pinion and a ring gear. The sun gear is connected to the axle. The planet pinion engages the sun gear and the ring gear. The ring gear is connected to the cam.

     DETAILED DESCRIPTION OF INVENTION  
       [0013]     The following description is a best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.  
         [0014]     Referring to  FIGS. 2 and 3 , a line-arranging mechanism  20  comprises a knob  25 , a cam  21 , an axle  22 , a sliding element  23  and a transmitting mechanism  24  (shown by  FIG. 3 ). The knob  25  comprises a protrusion  251  and a first engaging portion  252 . A force is exerted on the protrusion  251  for rotating the axle  22 . The axle  22  comprises a second engaging portion  221  which is connected to the first engaging portion  252 , thereby, the knob  25  and the axle  22  rotate together for arranging the line. In this embodiment, the cam  21  is cannular and comprises an inclined surface  211  located in the rim of the cam  21 . The axle is installed in the cam  21 . In this embodiment, the axle  22  is approximately at the center of the cam  21 . A space  28  between the axle  22  and the cam  21  contains the line (not shown). The sliding element  23  is movably installed on the inclined surface  211  and comprises a hole  231  through which the line passes. The transmitting mechanism  24  is installed at the bottom of the line-arranging mechanism  20  and connects to the cam  21  and the axle  22 .  
         [0015]     The transmitting mechanism  24  is a planetary gear system which comprises a sun gear  241 , a planet pinion  242  and a ring gear  243 . The sun gear  241  is connected to the axle  22 . The planet pinion  242  engages the sun gear  241  and the ring gear  243 . The ring gear  243  is connected to the cam  21 . The transmission ratio of the sun gear  241  and the ring gear  243  ranges from 3/1 to 20/1. In this embodiment, the transmission ratio of the sun gear  241  and the ring gear  243  is 8/1. When the sun gear  241  turns eight revolutions, the ring gear  243  turns one revolution. When the axle  22  turns eight revolutions, the cam  21  turns a revolution. The inclined surface  211  comprises a high point H and a low point L. When the cam  21  turns one-second revolution (the axle  22  turns four revolutions), the sliding element  23  arrives the high point H. When the cam  21  turns another one-second revolution, the sliding element  23  returns the low point L again.  
         [0016]      FIGS. 3 and 4 A to  4 C are schematic views showing a transmitting mechanism of the invention to arrange a line. Referring to  FIG. 4A , the line-arranging mechanism  20  further comprises a shell  26  for covering the cam  21 , the axle  22 , the sliding element  23  and the transmitting mechanism  24 . The line (not shown) enters the cam  21  from the shell  26 . The shell  26  comprises a groove  261  on the side of the shell. The sliding element  23  is installed on the inclined surface  211  and moves at an incline along the groove  261 .  
         [0017]     Referring to  FIGS. 3 and 4 A, the power line  27  enters the line-arranging mechanism  20  and then passes through the hole  231 . The power line  27  is arranged by the user to turn the protrusion  251  of the knob  25  along an arrow a. The knob  25  links the axle  22  to rotate the axle  22 . The axle  22  links the sun gear  241  of the transmitting mechanism  24  to rotate the sun gear  241  along the arrow a. The sun gear  241  links the planet pinion  242  to rotate the ring gear  243  along an arrow b, thus the cam rotates along the arrow b.  
         [0018]     Referring to  FIG. 4B , when the knob  25  rotates a revolution along the arrow a, the cam  21  rotates one-eighth revolution. The sliding element  23  in the grove  261  is pushed upward along the inclined surface  211  by rotating the cam  21 . In this embodiment, when the knob  25  rotates a revolution (the cam  21  rotates one-eighth of a revolution), the sliding element  23  rises a height H equal to a diameter of the power line  27 . Referring to  FIG. 4C , when the knob  25  rotates four revolutions, the cam rotates one-second revolution, thus, the sliding element  23  moves at the high point H and the power line  27  is wound four revolutions on the axle  22 . When the knob  25  proceeds to rotate four revolutions, the knob  25  moves downward along the inclined surface  211 . The power line  27  is arranged to cover the last wound power line  27  in order. The power line  27  is wound four revolutions per a layer on the axle  22 . The space  28  contains the wound power line  27 .  
         [0019]     The invention arranges the power line  27  in order without a complex mechanism, for example, a motor, a lead screw, and a bearing.  
         [0020]     While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
