するデイジタイザのカーソル。[Claims for Utility Model Registration] Used in combination with a tablet, a voltage is induced by a magnetic field formed by an alternating current flowing through the grid conductor of the tablet, and a current flowing through its own coil causes the tablet to In a digitizer cursor that measures the coordinate position of the coil on the tablet by inducing a voltage in another grid conductor, the cursor includes a tuned circuit for detecting the cursor position and a tuned circuit for detecting switch information. The tuned circuit for detecting the cursor position is composed of a first coil and a first capacitor connected to the first coil and forming a circuit tuned to the frequency of the alternating current for detecting the cursor position. The tuned circuit for detecting switch information includes a second coil, a second capacitor connected to the second coil, a plurality of capacitors connected in parallel to the second capacitor, and a plurality of capacitors connected in parallel to the second capacitor. a switch provided for each of the capacitors for controlling whether or not to connect the capacitor in parallel with the second capacitor, and by operating the switch, the cursor position detection It is possible to configure multiple types of tuning circuits each tuned to the frequency of the AC current for detecting multiple types of switch information set within a frequency band different from the frequency of the AC current. While operating in the position detection mode, the AC current for detecting the cursor position is applied to measure the cursor position, and while operating in the switch information detection mode, the AC current of multiple types of frequencies for detecting switch information is applied in a time-sharing manner. A digitizer cursor characterized by detecting flow switch information.
