Abstract

Official abstract text for this publication.

An ink jet apparatus includes: a head that discharges liquid; a circuit substrate that has a drive circuit for driving the head; a heat sink which has a part that is in direct or indirect contact with the circuit substrate and is able to dissipate heat generated in the circuit substrate; and a fan that generates air flow capable of cooling the heat sink. The heat sink is configured such that the air flow is not directly blown against the drive circuit and such that the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.

First claim

Opening claim text (preview).

What is claimed is: 1 . An ink jet apparatus, comprising: a head that discharges liquid; a circuit substrate that has a drive circuit for driving the head; a heat sink which has a part that is in direct or indirect contact with the circuit substrate and is able to dissipate heat generated in the circuit substrate; and a fan that generates air flow capable of cooling the heat sink, wherein the heat sink is configured such that the air flow is not directly blown against the drive circuit and such that the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit. 2 . The ink jet apparatus according to claim 1 , wherein the fan is disposed to face the drive circuit and the heat sink is disposed between the drive circuit and the fan.
