Manipulating apparatus and mobile terminal including the same

A manipulating apparatus including a chassis provided with a manipulating portion with which an input manipulation is carried out, said manipulating portion comprising:

• a key top exposed to an outside of said chassis through an opening portion, which said chassis has, and a key main body having a base portion on which said key top is formed within said chassis;
• and
• a circuit board having a detecting portion for detecting an input manipulation using the desired key top, said detecting portion being disposed in a position corresponding to said key top, wherein
• said base portion has a fulcrum point portion protruding in a direction of becoming close to said circuit board and being brought into contact with said circuit board, thereby becoming a fulcrum point for inclination of said key main body in a phase of depressing of the desired key top, and
• an urging member for urging said key main body to a side of said circuit board is provided between said chassis and said key main body.

A mobile terminal comprising

• a manipulating apparatus including a chassis provided with a manipulating portion with which an input manipulation is carried out, said manipulating portion including:
• a key top exposed to an outside of said chassis through an opening portion, which said chassis has, and a key main body having a base portion on which said key top is formed within said chassis;
• a circuit board in which a detecting portion is disposed in a position corresponding to said key top;
• and
• a flat plate-shaped elastic body interposed between said key main body and said detecting portion, wherein
• said elastic body is provided integrally with said base portion,
• said elastic body has a protrusion portion which protrudes from a surface facing said detecting portion and which is adapted to press said detecting portion, and
• said base portion has a fulcrum point portion which protrudes from said base portion toward said circuit board to be brought into contact with said circuit board, and which becomes a fulcrum point for inclination of said key main body in a phase of depressing said key top.
