<P>PROBLEM TO BE SOLVED: To stabilize recording properties by fully radiating heat of a drive circuit without increasing the size of the entire apparatus. <P>SOLUTION: The recording apparatus is provided with a head holder 8 for holding a recording head 1 to discharge ink through selective driving, a heat radiator plate 61 to radiate heat of the drive circuit 12a and a head-side circuit board 22 composed of a heat-conductive base material. A flexible wiring member 12 on which the drive circuit 12a of the recording head 1 is mounted and which connects the head-side circuit board 22 as the drive circuit 12a is taken around the inside of the head holder from the front side to the rear side, held in heat conductive contact with the heat radiator plate 61. One edge of the side wall 61b of the heat radiator plate 61 elongating in the upward and downward direction is held in heat conductive contact with the head-side circuit board 22. <P>COPYRIGHT: (C)2008,JPO&INPIT |
