Abstract
Abstract A recording device having a highly integrated recording head, which can perform high-quality high-speed printing of halftone image and which is compact and inexpensive to manufacture and can work at reduced running cost (with no need of replacing its recording head due to contamination with ink) and at saved power consumption. The recording device comprises an ink feeding unit for applying ultraviolet curing ink to an image transfer intermediate, an ultraviolet ink-curing head for selectively ultraviolet curing ink applied to the image transfer intermediate according to an image pattern, a platen for pressing a recording medium against the image transfer intermediate to transfer not-cured ink from the image transfer intermediate onto the recording medium, ultraviolet thermal ink-curing unit for fixing the ink on the recording medium and an ink removing unit for removing residual ink from the image transfer intermediate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
A recording device for recording an image pattern on a recording medium by ink onto an image transfer intermediate and further transferring the inked image pattern onto the recording medium, which is provided with ink applying means for applying a coat of liquid ink on the image transfer intermediate, ink curing means for selectively curing the liquid ink coat on the image transfer intermediate according to the image pattern and transfer means for transferring the recording medium into contact with the image transfer intermediate to transfer still not-cured ink from the image transfer intermediate onto the recording medium.
Claim 2
Dependent Claim
98 words
A recording device for recording an image pattern on a recording medium by ink onto an image transfer intermediate and further transferring the inked image pattern onto the recording medium, which is provided with ink applying means for applying a coat of liquid ink on the image transfer intermediate, ink curing means for selectively curing the liquid ink coat on the image transfer intermediate according to the image pattern and transfer means for transferring the recording medium into contact with the image transfer intermediate to transfer still not-cured ink from the image transfer intermediate onto the recording medium.
Claim 3
Dependent Claim
26 words
A recording device as defined in claim 1, wherein the ink is ultraviolet curing ink and the ink curing means is provided with ultraviolet irradiation unit.
Claim 4
Dependent Claim
51 words
A recording device as defined in claim 2, wherein the ink curing means is provided with a deformable mirror deformably formed for reflecting ultraviolet from the ultraviolet irradiation unit at an angle suitable for the image pattern to be recorded and a slit for passing reflected light from the deformable mirror.
Claim 5
Dependent Claim
42 words
A recording device as defined in claim 3, wherein the deformable mirror comprises a cantilever having a mirror surface and driving portion for driving the cantilever by applying any one of heat, electric field and electrostatic field to deform the mirror surface.
Claim 6
Dependent Claim
52 words
A recording device as defined in claim 2, wherein the image transfer intermediate is formed of transparent member and the ultraviolet irradiation unit is disposed within the image transfer intermediate to apply ultraviolet from opposite side to the ink applied surface of the image transfer intermediate to a coat of the ink.
Claim 7
Dependent Claim
32 words
A recording device as defined in claim 1, wherein the ink is thermal curing ink and the ink curing means has heating means for heating the surface of the image transfer intermediate.
Claim 8
Dependent Claim
47 words
A recording device as defined in claim 6, wherein the heating means is composed of a resistance heating type micro-heater, an insulation film formed on the micro-heater and a heater pad formed on the insulation film and having a convex surface for contacting the image transfer intermediate.
