Patent ID: 8723842

Claim:
A hand-held electronic appliance comprising: a position detecting apparatus ( 194 , 196 ; 502 , 506 ); a position pointing device ( 24 ) for use with the position detecting apparatus comprising a housing ( 12 ) for receiving a circuit, the circuit being formed as a modular unit having a coil member ( 18 , 20 ), a magnetic core body ( 8 , 14 ), a return wire ( 32 ) and a circuit component ( 10 ), the return wire ( 32 ) electrically connecting the coil member ( 18 , 20 ) to the circuit component for delivering an electrical signal that changes a frequency of the circuit, the housing having a housing inner surface with a housing groove ( 30 ), the coil member and the return wire being encapsulated by an encapsulation ( 21 ), the encapsulation ( 21 ) having a protrusion ( 23 ) for covering and encapsulating the return wire between a first coil and a last coil of said coil member, the protrusion having an outer surface received in the housing groove ( 30 ), which extends from a terminal end of the housing to a first location within the housing such that the modular unit is slidingly disposed into said housing from said terminal end toward said first location, said protrusion ( 23 ) further having an inner surface forming a protrusion inner surface groove that receives and is in direct contact with the return wire ( 23 ); and means ( 105 ) for releaseably attaching the position pointing device to the hand-held electronic appliance.
