1. A power reception apparatus, comprising:

  • a secondary coil which receives electric power in a non-contact manner from a primary coil which is disposed on a plane defined by a front-rear direction and a left-right direction which are at right angles to each other;

    a drive part for changing a relative position of the secondary coil on the plane relative to the primary coil;

    a display unit; and

    a processing unit for processing an image to be displayed on the display unit,wherein the processing unit calculates the relative position and a yaw angle of the secondary coil relative to the primary coil based on a coupling coefficient between the primary coil and the secondary coil, and a change with time in the coupling coefficient, andthe processing unit displays information on the relative position and information on the yaw angle of the secondary coil on the display unit,the processing unit determines a target zone on the plane which includes the primary coil,the processing unit displays information on the relative position and information on the yaw angle of the secondary coil on the display unit in an event that the secondary coil is not included in the target zone in relation to the left-right direction, andthe processing unit issues a predetermined notice when a change takes place from a state where the secondary coil is not included in the target zone in relation to the left-right direction to a state where the secondary coil is included in the target zone in relation to the left-right direction.
