Claim:
1. A power reception control device includable in a non-contact power transmission system that performs non-contact power transmission from a power transmission device to a power reception device through a primary coil and a secondary coil, the power reception device supplying power to a first load, the power reception control device comprising: a power reception section that is adapted to be connected to the first load and that converts an induced voltage in the secondary coil into a direct-current voltage; a load modulation section that modulates a second load; a power terminal that is configured to be electrically connected to the first load; and a power supply control section that controls the power supplied to the first load via the power terminal, the load modulation section being configured to transmit information from the power reception device to the power transmission device through the secondary coil and the primary coil utilizing load modulation of the second load, and the power supply control section reducing the power supplied to the first load when a power-reception-side control section controls the load modulation section to transmit the information from the power reception device to the power transmission device.
