  • Publication number: 20240393382
    Abstract: A contact detection apparatus includes an electrostatic sensor, and a determination processor detecting whether a conductor comes into contact with a plurality of detection regions. The determination processor includes a storage unit, a determination reference value setting unit, and a determination processing unit. The determination reference value setting unit determines a detection region in which a difference between a capacitance equivalent value and a setting reference value exceeds a threshold value as a contact region where the conductor is in contact, determines a detection region in which the difference is equal to or less than the threshold value as a non-contact region where the conductor is not in contact, and sets the setting reference value corresponding to the non-contact region as a determination reference value of the contact region for the contact region when determining that the contact region exists and that the non-contact region exists.
