Abstract

PURPOSE: To detect a cursor position without error by detecting electromotive force induced in the cursor and by performing synchronous detection for a driving current and by operating this output voltage in case that induction phenomenan are used to detect the position of the cursor, namely, the center of the winding.
CONSTITUTION: Control circuit 15 controls driving line selector switch 11 to select the x-direction or y-direction driving line. Meanwhile, electromotive force induced in cursor 12 is detected by sense amplifier 14 and is subjected to synchronous detection in 16 for a driving current, and operation circuit 17 calculates the position of cursor 12 in the x or y direction from this output voltage. Data output buffer 18 obtains coordinates of cursor 12 on a basis of the position of the selected driving line and positions x and y of cursor 12 in the driving line. As a result, the position of the cursor can be calculated similarly even around the loop because the loop is not folded, and the cursor position without error can be detected because driving lines can be constituted in the same plane.
