POSITION DEVIATION DETECTION DEVICE AND ELECTRONIC APPARATUS

摘要

This position deviation detection device (110) is provided with: a comparator (120) that compares the current induced in a reception coil (302) of a reception apparatus (RX) (300) to which electrical power is supplied from a transmission apparatus (TX) (200) by means of a contactless electricity supply method; a frequency counter (140) that is connected to the comparator and that counts the transmission frequency (fi) transmitted from the transmission apparatus; and a resistor (160) that stores the count value (Fi­) of the frequency counter. Provided is a position deviation detection device (110) that can detect position deviations of a reception apparatus over a transmission apparatus during charging.
