PROBLEM TO BE SOLVED: To obtain a head, a printer and a system of printer and image processor in which a board and an aperture can be cooled. SOLUTION: In order to prevent deterioration of image quality due to decrease of emission caused by heat generated through flickering of LEDs 12b, 12c and 12d and to prevent a board 12a from being heated up to the melting pint of plastic composing a carriage 9, the board 12a is made of a metal plate having high thermal conductivity and means for dissipating heat of the board 12a is provided. The heat dissipating means for the board 12a has vents 31 on the opposite sides of the box type board supporting section 9a of the carriage 9 in the traveling direction thereof. Heat of an aperture 29 is dissipated through the heat dissipating means for the board 12a by making the aperture 29 of a metal plate having high thermal conductivity and supporting the aperture 29 on the carriage 9. |
