摘要

PROBLEM TO BE SOLVED: To provide a printing apparatus to perform stable power supply to a head unit mounted on a carriage without using wiring which needs to be moved according to the movement of the carriage.SOLUTION: A printing apparatus comprises: a head unit provided with a discharge unit D which discharges a liquid; a carriage 32 which has the head unit mounted thereon and is movable; a power transmission unit for delivering at least a part of supplied power to the head unit; and a power supply unit for supplying power to the power transmission unit. The power transmission unit includes a conductor 21 provided on the opposite side of the carriage 32 across a transport passage and a conductor 22 provided to the carriage 32, and transmits power supplied from the power supply unit to the head unit through a coupling capacitance formed by the conductors 21 and 22. The power supply unit supplies different amounts of power to the power transmission unit depending on the type of a recording medium which is in the transport passage.
