Title: Ink jet recorder
Inventor: YAMADA TAKEHIRO
IPC: B41J2/175
Filed: 1985-11-11
Abstract: PURPOSE:To assure that a stable image is recorded despite varying environmental conditions by controlling the temperature of a heat exchange element while regulating the time change rate of ink temperature to a prearranged value and maintaining the ink temperature within a range in which ink can be of small diameter particles of stable size. CONSTITUTION:If ink temperature exceed a prearranged level, this state is detected by a temperature control circuit 16 which inputs a detection signal from a temperature sensor 15. Then a heat exchange element 14 is driven to cool the ink so that the temperatures of the ink injected from the nozzle 2 of a recording head A will not exceed an upper limit value Tmax. On the other hand, if said temperature drops below a prearranged level, the ink will be heated so that the temperatures will not fall below a lower limit value Tmin. Thus the temperature of the ink injected from the nozzle are regulated to stay between the Tmax and Tmin. Further, temperature is controlled so as to allow the time change rate of temperature to fall below (dT/dt)max.
