DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for irradiating a recording medium coated with a sublimation dye with a laser beam to perform recording by suction. It relates to a mouthpiece cartridge to be used.

[0002]

2. Description of the Related Art Conventionally, as a recording method using a sublimation type dye, a transfer film coated with a sublimation type dye is pressed against a recording medium and the transfer film is heated by a thermal head to evaporate the sublimation dye. In general, a method of transferring the image data to a recording medium is used. However, the transfer method has a problem that a transfer film different from the recording medium must be used. Therefore, as a recording method that replaces such a transfer method using a sublimation dye, the present applicant has
A method has been developed in which a sublimation dye is applied to the recording medium itself, and the sublimation dye is sublimated, scattered and removed by irradiating the sublimation dye application surface with a laser beam to perform recording. As an apparatus for performing this recording, FIG.
As shown in the figure, the recording medium 1 is held on the outer peripheral surface of a cylindrical rotary drum 2, the rotary drum 2 is driven to rotate, and further, the recording medium 1 held on the rotary drum 2 is irradiated with laser light. A head having a structure in which the head 3 is moved along the rotating drum 2 to record an image on the entire recording medium 1 has been developed.

[0003]

However, when recording was performed with this recording apparatus, the dye released by sublimation and scattering by laser light irradiation adhered to the objective lens 4 of the recording head 3 and was relatively short. There has been a problem that the objective lens is polluted with time, thereby deteriorating the quality of the recorded image, or adhere to surrounding members and contaminate the machine. In order to solve this problem, it is conceivable to attach a suction port of the suction hose 10 near the position where the recording head 3 irradiates the laser beam, and perform the recording operation while sucking and removing the dye released by the laser beam irradiation.

However, when this method is carried out, the sucked dye adheres and accumulates in the suction mouth of the suction hose 10 and in the middle thereof, and clogging occurs in a relatively short time to lower the suction capacity. The problem arises that the suction hose has to be replaced. In addition, simply by arranging the suction port of the suction hose 10 near the laser beam irradiation position,
There was also a problem that the suction effect of the released dye was low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is used by attaching to a tip of a suction hose used for sucking and removing a dye emitted by laser light irradiation, so that the sucked dye is fixed. It is an object of the present invention to provide a mouthpiece cartridge having a configuration capable of efficiently coping with dye clogging by collecting at a location and exchanging the location.

Another object of the present invention is to provide a suction cartridge having a structure capable of efficiently sucking and removing dyes emitted by laser light irradiation.

According to a sixth aspect of the present invention, a plurality of fins are formed in the storage space.

[0013]

According to the first aspect of the present invention, the dye discharged by sublimation or the like when the recording head irradiates the recording medium with the laser beam can be sucked into the suction cartridge together with the air by the above-mentioned structure. When passing through the storage space, the flow velocity decreases or the flow direction changes, so that the dye often comes into contact with the inner surface of the storage space, so that the dye solidifies and adheres to the surrounding wall surface. The easy dye can be adhered to the inner surface of the storage space and captured, so that the clogging of the downstream suction hose can be prevented for a long time. In addition, when the amount of dye attached to the storage space increases, it can be easily dealt with by removing the suction cartridge from the recording head and replacing it with a new one.

The carriage 7 is held by a linear motor 8 provided in parallel along the rotary drum 2. Thus, the recording head 3 travels in the longitudinal direction of the rotary drum 2 by the linear motor 8, and can scan the recording medium 1 in the longitudinal direction of the rotary drum 2. In the present embodiment, the rotary drum 2 is arranged horizontally, and is configured to be rotationally driven in the direction in which the laser beam irradiation position of the recording head 3 travels upward, that is, in the direction of arrow B.

Reference numeral 11 denotes a lens barrel holding the objective lens 4 of the recording head 3, reference numeral 12 denotes a suction cartridge attached to the recording head 3 so as to surround the lens barrel 11, and reference numeral 13 denotes a suction hose connected to the suction cartridge 12. It is.
The suction cartridge 12 includes the objective lens 4 and the rotating drum 2.
A lens cover 16 which is arranged to surround the laser light path between the recording medium 1 and the upper surface, and forms a lens front space 15;
, An inlet 18 communicating with the front space 15 of the lens, a storage space 19 communicating with the inlet 18, and the storage space 1
It has a storage portion 21 having an outlet 20 for communicating the nozzle 9 with the suction hose 13. The storage space 19 has a substantially rectangular parallelepiped shape, and the flow rate of the air flowing inside the storage space 19 is
It is made larger in cross-sectional area than the inlet 18 and the suction hose 13 so as to be considerably smaller than the inside of the suction hose 13. The inlet 18 is made as short as possible so that the dye does not adhere to the inner surface. In other words, the storage space 19 is provided as close to the lens front space 15 as possible. The mouthpiece cartridge 12 is arranged so that the storage part 21 is located above the lens cover part 16, and in this state, the inlet 18 is formed on the bottom surface 19 a of the storage space 19, and the area of the rear surface 19 b is formed on the rear surface 19 b.

After the recording medium 1 is held on the outer peripheral surface of the rotary drum 2 by vacuum suction or electrostatic suction, the rotary drum 2 rotates in the direction shown by the arrow B, and the recording head 3 emits a laser beam during the rotation. The image is recorded by selectively sublimating and removing the sublimation dye on the surface of the recording medium 1. During the recording, the recording position is moved by moving the recording head 3 in the longitudinal direction of the rotary drum 2, and the image is recorded on the entire surface of the recording medium 1.

During the above recording operation, the suction cartridge 12 is constantly sucked by the suction means 28 via the suction hose 13, and therefore, the air is constantly sucked from the inlet 18. During the recording operation, as described above, the laser light applied to the recording medium 1 causes the dye to be released from the laser light irradiation position in order to sublimate the sublimation dye, but the emission position is surrounded by the lens cover 16. Therefore, the dye hardly scatters to the outside and is immediately sucked into the storage space 19 through the inlet 18. At this time, an upward airflow is generated in the front space 15 of the lens by the rotation of the rotary drum 2 in the direction of arrow B, and this airflow is also transmitted to the storage space 1.

The airflow from the inlet 18 changes its direction toward the outlet 20 or collides with the back surface 19b around the outlet 20, so that the storage space 1
The number of opportunities to contact the inner surface of the storage space 9 increases, and the dye in the air efficiently adheres to the inner surface of the storage space 19 and is captured. Thus, the concentration of the dye in the air sucked by the suction hose 13 becomes extremely low, so that the suction hose 13 is less likely to be adhered and clogged on the inner surface of the suction hose 13, and the downstream filter 27.
Life can be extended. In addition, even if the dye adheres and accumulates in the storage space 19, since the cross-sectional area is large, the suction resistance is small, and the suction failure does not occur.
