Abstract

An ink jet recording apparatus comprising recording heads each of which has a nozzle for jetting out light-curing ink which cures when applied to light towards a recording sheet, a light-emitting device equipped with a light source which emits ink-curing light from a luminous tube by discharging at the base, a base temperature controller for controlling the temperature of said base, and a luminous tube temperature controller for controlling the temperature of said luminous tube.

Claims

1. An ink jet recording apparatus comprising recording heads each of which has a nozzle for jetting out light-curing ink which cures when applied to light towards a recording sheet,

a light-emitting device equipped with a light source which emits ink-curing light from a luminous tube by discharging at the base,

a base temperature adjuster for adjusting the temperature of said base, and

a luminous tube temperature adjuster for adjusting the temperature of said luminous tube.

2. The ink jet recording apparatus of claim 1, further comprising

a base temperature detector for detecting the temperature of said base, and

a base temperature controller for controlling said base temperature adjuster to keep said base at a preset temperature according to the temperature of said base detected by said base temperature detector.

3. The ink jet recording apparatus of claim 1, further comprising

a luminous tube temperature detector for detecting the temperature of said luminous tube, and

a luminous tube temperature controller for controlling said luminous tube temperature adjuster to keep said luminous tube at a preset temperature according to the temperature of the said luminous tube detected by said luminous tube temperature detector.

4. The ink jet recording apparatus of claim 1, wherein said light-emitting device is equipped with a reflection member for reflecting diffused light coming from said light source onto said recording medium and

said luminous tube temperature adjuster adjusts the temperature of said luminous tube by adjusting the temperature of said reflection member.

5. The ink jet recording apparatus of claim 1, wherein a cover member is provided to cover said light source and said cover contains a partitioning member to separate the base section which contains said base from a luminous tube section which contains said luminous tube.

6. The ink jet recording apparatus of claim 1, wherein at least one of said base temperature adjuster and said luminous tube temperature adjuster is a cooling fan.

7. The ink jet recording apparatus of claim 6, wherein the rotating speed of said cooling fan is variably controlled by temperature.

8. The ink jet recording apparatus of claim 6, wherein said cooling fan is variably controlled to run and stop by temperature.

9. The ink jet recording apparatus of claim 1, wherein at least one of said base temperature adjuster and said luminous tube temperature adjuster is a Peltier module which variably controls to cool the heat by temperature.

10. The ink jet recording apparatus of claim 1, wherein

said light source is a low-pressure mercury lamp.
