Document Type and Number:
Japanese Patent JP7077905
Kind Code:
B2
Abstract:
A heater device includes a contact determination unit for determining contact or non-contact of an object based on a change in capacitance between a plurality of electrodes. The contact determination unit is configured to determine (i) the contact of the object in response to a determination that the change in capacitance between the plurality of electrodes per predetermined unit time is a change in one direction and equal to or larger than a first determination threshold value. The contact determination unit is configured to determine (ii) the non-contact of the object in response to a determination that the change in capacitance between the plurality of electrodes per predetermined unit time is a change in a direction opposite to the one direction and equal to or larger than a second determination threshold value.
