Abstract

PURPOSE:To record in heat sensitive with high speed and high resolution by transfering a thermally meltable ink on an object before a solidification and being heated immediately before the transfer from a transfering side. CONSTITUTION:Thermally meltable ink is scaned by the laser beem from an Ar laser oscillator 1 after being formed an image on an ink sheet 7 through AO modurator 2, a beem expander 3, a revolution multimirror 4, and an ftheta lense 5. The thermally meltable ink on the ink sheet 7 is contacted to the recording paper 9 being sent synchronously before a solidification from the melted condition, and applied the constant pressure by pressure rollers 8, then transferred on the recording paper.

Also, experimentally, there is a type that uses laser beam irradiation to transfer images instead of using a thermal head as a heating element. FIG. 2 shows a conventional example of a transfer type thermal recording system using a laser beam. In Figure 2, 1. is a laser beam,
2. is an ink sheet, 3. is recording paper, 4. is Backup Prora, 5. is a guide roller. Ink sheet 2. Laser beam irradiated on the back side of 1. With the energy of ink sheet 2. Heat the ink sheet 2. Recording paper 3. Selectively melt the ink facing the recording paper 3 to form the desired pattern. Transfer to. At this time, back up roller 4. and guide roller5. Ink sheet 2. and recording paper 3. Improves adhesion and transferability. In this way, in the method of melting and transferring ink by applying energy from behind the ink support or the recording paper, heat is transferred to the ink through the ink support or the recording paper. The recording paper is heated,
Since the ink must be melted, the energy efficiency is poor and the transfer speed cannot be increased. At the same time, the heat conduction in the plane direction of the ink support or recording paper is too large to be ignored, resulting in a resolution determined by the arrangement of the heat generating elements of the thermal head or a resolution determined by the spot diameter of the irradiated laser beam. It gets worse. In addition, in the type that generates heat or irradiates a laser beam from the back of the ink support, the temperature distribution of the ink layer during melt transfer is as follows:
The temperature of the surface to be transferred is the lowest, resulting in poor fixing performance.
On the other hand, with the type that heats the recording paper from the back side,
There are large variations in heat conduction due to differences in the thickness, moisture content, paper quality, etc. of the recording paper, and as a result, the transfer ability becomes dependent on the recording paper.

レーザ発振器を用いた場合より簡略できる。According to the author's experience, in the case of the conventional method of transferring by applying thermal energy from the back of the sheet, the threshold energy density required for recording is 0.2, although it depends on the heat-melting ink and the thickness of the sheet. ~0.6 J/cm2, and it has become fully possible to use a semiconductor laser oscillator, whose output has recently been significantly improved, as a laser light source. An example in this case is shown in FIG. In Figure 4, the AO in Figure 3
No modulator is required, and the desired pattern can be obtained by directly modulating the semiconductor laser oscillator, which is simpler than using a gas laser or solid-state laser oscillator.
