Abstract
An ink jet apparatus includes a head, a circuit substrate, a cover frame, a heat sink, a fan, and a wall section. The cover frame supports the circuit substrate that has a drive circuit that drives the head inside of the cover frame and has a through hole. The heat sink that dissipates heat generated in the circuit substrate is disposed inside of the cover frame and has a part that is in direct or indirect contact with the circuit substrate. The fan generates air flow and is arranged such that the fan and the heat sink face to each other via the through hole. The wall section is disposed inside of the cover frame such that the air flow is not directly blown against the drive circuit and the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.
