PROBLEM TO BE SOLVED: To enhance stability of waste ink while shortening the time for drying printed ink by employing a heat sink coupled thermally with heating components, e.g. a power supply motor, for transmitting heat to a printed recording medium or a waste ink storing section thereby utilizing generated heat effectively. SOLUTION: A printed board 4 fixed with circuit components is fixed to the inside of a power supply unit 1 having outer surface formed with a heat plate 6 for dissipating heat of a mounted heat generating component 5 to the outside of the unit. The storage section of a waste ink tank is formed by containing a waste ink absorber 2 in the waste ink tank. A heat sink 7 transferring heat to the waste ink tank is coupled thermally with the heat plate 6 of the power supply unit 1 through face contact with the heat plate and extends to the inner side face and the lower surface of the waste ink storage section thus transferring heat from the power supply unit 1 to each waste ink absorber 2. |
