Rotary manipulation type input apparatus

Abstract

A rotary manipulation type input apparatus is disclosed. The rotary manipulation type input apparatus including a rotatable wheel; a magnet joined to the bottom of the wheel; a printed circuit board having one or more detection elements mounted thereon, the detection elements detecting a rotation of the magnet; a base having the printed circuit board joined thereto; and a holder joined to the base and supporting the wheel such that the wheel is rotatable, where the holder includes a body portion, an inclination portion extending in a particular angle from the body portion, and a securing portion extending from an end of the inclination portion and joined to the base, and the inclination portion is made of metal, has a reduced thickness and has superior endurance to external impact.

1 . A rotary manipulation type input apparatus comprising:

       2 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the printed circuit board has one or more receiving holes formed therein in correspondence with the detection elements, and   at least a portion of the detection elements is inserted in the receiving holes.   
   
   
       3 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the body portion and the securing portion are made of metal.   
   
   
       4 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the base has one or more insertion holes in which at least a portion of the detection elements is positioned in correspondence with the receiving holes.   
   
   
       5 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the detection element is a Hall sensor or an MR sensor.   
   
   
       6 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the body portion has an insertion hole and one or more ledges formed adjacent to the insertion hole,   the wheel has securing protrusions protruding downwards,   and a washer having one or more rotation holes of predetermined central angles formed therein is inserted onto the ledges, the securing protrusions being inserted into the rotation holes.   
   
   
       7 . The rotary manipulation type input apparatus of  claim 1 , wherein
 the holder has one or more support portion holes, formed in positions corresponding to the detection elements, in which at least portions of the detection elements are positioned.   
   
   
       8 . The rotary manipulation type input apparatus of  claim 1 , further comprising:
 a center key formed at the center of the wheel; and   a dome button on the printed circuit board such that enables the center key to press the dome button.   
   
   
       9 . A rotary manipulation type input apparatus comprising:
 a rotatable wheel;   a magnet joined to the bottom of the wheel;   a printed circuit board having one or more detection elements mounted thereon, the detection elements detecting a rotation of the magnet;   a base having the printed circuit board joined thereto; and   an elastic holder joined to the base and supporting the wheel such that the wheel is rotatable.   
   
   
       10 . The rotary manipulation type input apparatus of  claim 9 , wherein at least a portion of the holder is made of metal. 
   
   
       11 . The rotary manipulation type input apparatus of  claim 9 , wherein
 the printed circuit board has one or more receiving holes formed therein in correspondence with the detection elements, and   at least a portion of the detection elements is inserted in the receiving holes.   
   
   
       12 . The rotary manipulation type input apparatus of  claim 9 , wherein
 the base has one or more insertion holes in which at least a portion of the detection elements is positioned in correspondence with the receiving holes.   
   
   
       13 . The rotary manipulation type input apparatus of  claim 9 , further comprising:
 a center key formed at the center of the wheel; and   a dome button on the printed circuit board such that enables the center key to press the dome button.
