<P>PROBLEM TO BE SOLVED: To provide a drawing device and a liquid supply device which generates convection of ink sufficiently irrespective of an amount of ink in an ink tank and suppresses a defect caused by settling of an ink component. <P>SOLUTION: The drawing device includes: a discharge head which discharges a liquid; a storage tank which stores the liquid; a first temperature adjusting part which adjusts a temperature of a part of the liquid in the storage tank; a second temperature adjusting part which is arranged in a position different from the first temperature adjusting part and adjusts a temperature of a part of the liquid in the storage tank; and a temperature adjusting part control part which controls the first temperature adjusting part and the second temperature adjusting part. The temperature of the part of the liquid adjusted by the first temperature adjusting part and the temperature of the part of the liquid adjusted by the second temperature adjusting part are different. The temperature adjusting part control part adjusts a temperature difference between the temperature of the part of the liquid adjusted by the first temperature adjusting part and the temperature of the part of the liquid adjusted by the second temperature adjusting part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
