According to one embodiment, there is provided a power reception device. A power reception coil receives power from a power supply device in a non-contact manner. A power reception unit causes the received power as a charging current to flow to a load. A notification unit notifies that a relative position of the power reception device to the power supply device is inappropriate. A control unit starts charging by the charging current which is set to a first current value and controls the charging current so as to gradually increase the charging current. If the charging is stopped before the charging current reaches a second current value larger than the first current value, notification is performed that the relative position of the power reception device to the power supply device is inappropriate.

A printing device includes: a printing unit printing on a recording paper; a feeder unit having a roller that rotates about a shaft and feeds the recording paper and a motor that rotates the shaft; a detection unit detecting the rotation of the shaft; and a control unit controlling the printing unit. The control unit calculates an electrifying time during which the printing unit is electrified and a non-electrifying time during which the printing unit is not electrified following the electrifying time, based on a detection signal from the detection unit. When the calculated non-electrifying time is less than a predetermined time, the control unit corrects the non-electrifying time in such a way that the non-electrifying time becomes equal to or longer than the predetermined time, and causes the printing unit to print.

A printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.
