    • A coordinate reader comprises first and second conductor loops each having an electrical conductor so that electrical conductors of the respective conductor loops are juxtaposed on an electrically insulating board, a cosine function generator connected to one of the first and second conductor loops, a sine function generator connected to the other of the first and second conductor loops, a cursor incorporating a magnetic flux detecting coil for detecting magnetic fluxes generated in the conductor loops excited by the cosine and sine function generators, and a processor. The processor processes and controls operations of the aforementioned components to detect coordinates of the cursor.
    • 坐标读取器包括第一和第二导体环,每个导体环具有电导体,使得各个导体环的电导体并置在电绝缘板上,余弦函数发生器连接到第一和第二导体环之一,正弦函数发生器 连接到第一和第二导体环路中的另一个,光标包括用于检测由余弦和正弦函数发生器激励的导体环路中产生的磁通量的磁通量检测线圈,以及处理器。 处理器处理和控制上述组件的操作以检测光标的坐标。
