Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel recording apparatus, and more particularly to a recording apparatus capable of clearly highlighting a portion to be emphasized.

[0002]

2. Description of the Related Art An offset printing apparatus is well known as a method for forming an image by dividing a surface of a recording material into a liquid adhesive area and a non-liquid adhesive area. Further, the applicant of the present invention discloses in JP-A-3-178478 that selectively or selectively and reversibly the surface of a recording medium having a surface which has a low receding contact angle when heated and brought into contact with a liquid by an easy means. A recording device is proposed in which a desired pattern area can be formed selectively (that can be repeatedly used).

FIG. 6 shows an example of a recording apparatus proposed in Japanese Patent Laid-Open No. 3-178478, which heats a surface of a recording material with a recording material containing a coloring material to form a visible image according to the heating temperature. It is a figure which shows the structural example. In this recording apparatus, a belt-shaped belt member 50 coated with a recording material having a surface on which a receding contact angle is lowered when the surface of the belt-shaped member is brought into contact with a liquid in a heated state, and the belt member 50 are stretched. Pair of transport rollers 51, 52 rotated in a state, and the latent image forming liquid holding member 5 provided near the lower side of one of the transport rollers 51.
The thermal head unit 54 for forming a latent image by selectively heating in accordance with a recording signal under the latent image forming liquid 3
And a developing sponge portion 55 that visualizes the formed latent image by using an ink containing a predetermined color material, and recording paper as a recording material that is provided so as to face the other conveying roller 52. A transfer roller 57 that conveys 56 in a state of being pressed against the belt member 50, a cleaner unit 58 that removes the recording material after being transferred to the recording paper 56, and a thermal head unit 54 that is selectively heated. An image removing heater unit 59 is provided for erasing the formed latent image by heating the entire surface.

In this recording apparatus, the recording medium of the belt member 50 is heated on the basis of the image signal supplied to the thermal head section 54 to form a latent image corresponding to the image signal, and the developing sponge section 55 supplies the latent image. The latent image is made into a visible image by the predetermined color ink. The region of the belt member 50 which is a visible image is the conveyance rollers 51,
It is conveyed to the position of the transfer roller 57 by 52 and is transferred to the recording paper 56 conveyed in synchronization. Then, the residual ink on the belt member 50 is cleaned by the cleaner unit 58, and the latent image is erased by the image removing heater unit 59 to prepare for the next image formation. As described above, the latent image formation by the selective heating, the visible image formation (development), the transfer to the recording paper, the cleaning, and the latent image erasing by the entire surface heating are repeatedly performed as one cycle, so that the recording paper 56 is continuously desired. It is possible to provide a recording device capable of forming the image of.

[0005]

In the above recording apparatus, since the transfer roller 57 is always in contact with the recording medium, when the background stain occurs during non-recording, ink adheres to the transfer roller 57 to cause the recording paper 56 to remain. Sometimes the back side got dirty. Further, when the recording apparatus is activated, dust or the like adheres to the recording body, which may cause the soiling to stain the transfer roller 57.

The present invention has been made in view of the above problems, and provides a recording apparatus adopting the recording method proposed in Japanese Patent Application Laid-Open No. 3-178478, which does not stain the recording paper. Is intended.

[0010]

EXAMPLES Examples of the present invention will be described below. FIG. 1 is a diagram showing a first embodiment of the present invention. This recording apparatus includes a belt-shaped belt member 1 coated with a recording material having a surface having a receding contact angle that decreases when brought into contact with a liquid in a heated state, and a pair of belt members 1 rotated in a stretched state. The transfer rollers 2 and 3 and a thermal image forming latent image by selectively heating the latent image forming liquid holding member 4 provided near the lower side of one of the transfer rollers 2 under the latent image forming liquid according to a recording signal. A head portion 5, a developing sponge portion 6 that visualizes the formed latent image by using an ink containing a predetermined color material, and a recording material that is provided so as to face the other conveying roller 3. By the transfer roller 8 which conveys the recording paper 7 in the state of being pressed against the recording medium, the cleaner portion 10 which removes the ink after being transferred to the recording paper 7, and the thermal head portion 5 which is selectively heated. The formed latent image on the entire surface And a dividing image heater unit 11 for erasing by heat.

FIG. 2 is an enlarged view of the periphery of the transfer roller 8 of the recording apparatus. A transfer roller cleaner 9 is provided on the opposite side of the transfer roller 8 from the belt member 1 side, and is configured to clean the surface of the transfer roller 8 constantly or as needed. Therefore, the belt member 1 is soiled with ink during non-recording, which causes the transfer roller 8
Even if ink adheres to the recording paper 7, the transfer roller 8 is cleaned by the transfer roller cleaner 9, so that the recording paper 7 is prevented from being contaminated. As the transfer roller cleaner 9, a porous body, a non-woven fabric, a rubber blade or the like can be used.

FIG. 3 is a diagram showing a second embodiment of the present invention. The transfer roller 8 is not provided with a cleaning mechanism, and the belt member 1 and the transfer roller 8 are cleaned by passing the cleaning member 20 on the sheet through the transfer roller 8 only when the transfer roller 8 is soiled. Is also good. In this case, since the transfer roller cleaner 9 as shown in FIG. 2 does not have to be provided, there is an advantage that the mechanism is simple and the cost is low. It is desirable that the cleaning member 20 on the sheet has a good smoothness and easily absorbs ink. For example, a porous absorber, a blotter paper, etc. may be mentioned. Immediately after the recording apparatus is started up, dust adheres to the belt member 1 and the portion in contact with the developing roller 6 has weak ink repellency, and thus is susceptible to background stains. Therefore, immediately after the start-up, the transfer roller 8 may be cleaned by the method shown in FIG. 3 and then recording may be performed, and thereafter, the transfer roller 8 may be cleaned constantly or as needed.

FIGS. 4 and 5 show a third embodiment of the present invention. In this embodiment, the transfer roller 8 is rotatably supported by the movable shaft 25, and the movable shaft 25 can change the protrusion distance by the moving mechanism 24. Therefore, the movable shaft 25 supporting the transfer roller 8 at the time of non-transfer shown in FIG.
Can be placed away from. Further, at the time of transfer, by projecting the movable shaft 25 long as shown in FIG. 5, a visible image can be transferred onto the recording paper 7. According to this configuration, even if background stains occur during non-recording, it is possible to prevent stains on the recording paper 7 without ink being attached to the transfer roller 8.
