1. An electromagnetic induction-type information input device configured to acquire information input by a user using a writing tool, the information input device comprising:

  • a plurality of detection portions that are each configured to detect an output signal output from the writing tool and to output a detection result;

    a processor that is configured to;

    cause each of the plurality of detection portions to perform detection processing that detects the output signal;

    identify an identified detection portion based on the detection results output from the plurality of detection portions, the identified detection portion being a detection portion, among the plurality of detection portions, that has detected an output signal having a largest strength among the output signals detected by the plurality of detection portions;

    stop a supply of electric power to a non-identified detection portion, the non-identified detection portion being one or more of the plurality of detection portions other than the identified detection portion;

    cause the identified detection portion to perform the detection processing after the supply of electric power to the non-identified detection portion has been stopped; and

    identify a position of the writing tool, based on the detection result output from the identified detection portion.
