Patent ID: 8884932

Claim:
A pen type coordinate indicator, comprising: a core body protruding from a distal end of a chassis to form a pen tip; a first magnetic body having a distal end surface contacting said core body, the first magnetic body being wound around by a coil; a second magnetic body disposed such that a distal end surface thereof faces an proximal end surface of said first magnetic body; and a first elastic body and a second elastic body interposed between said proximal end surface of said first magnetic body and said distal end surface of said second magnetic body, wherein a distance between said end surfaces of said first and second magnetic bodies facing each other is changed by a pressing pressure applied to the pen tip of said core body, and wherein, during a first time section of pressure application, at least said first elastic body is elastically deformed by a pressing pressure until said proximal end surface of said first magnetic body or said distal end surface of said second magnetic body comes in contact with said second elastic body, and during a second time section of pressure application after said contact with the second elastic body has been made, in addition to said first elastic body, said second elastic body is elastically deformed by a further pressing pressure, whereby said pen type coordinate indicator has a pressing pressure sensitivity corresponding to the distance between said end surfaces of said first and second magnetic bodies facing each other and the pressing pressure sensitivity of the first time section is different from the pressing pressure sensitivity of the second time section.
