Abstract

PURPOSE:To enable a good printing to be carried out even for the transfer paper of a low smoothness by increasing the smoothness of the transfer paper, by a method wherein a smoothing means is contacted with the transfer paper supported by a platen, is moved thereon and the transfer paper is smoothed by the smoothing means prior to printing. CONSTITUTION:A smoothing apparatus is positioned in front of a thermal head 9 in the direction where the thermal head 9 keeps on printing, and smoothes the transfer paper 1 by pressing it in advance. Because a pressing component 5 presses the transfer paper 1 by pushing its edge against the transfer paper 1 supported with a platen 2, the metal, glass, ceramic, etc. efficient in wear resistance are used therefor. Further, the pressing component 5 is fixed to a support component 6 and is pressed, and a solenoid 7 and a spring 8 release pressing. By this moving the edge of the pressing component 5 in contact with the transfer paper 1, high pressure can be obtained and the fiber of the transfer paper can be more deformed than by a rolling method. Therefore, its smoothing can be promoted.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a printer, and particularly to a printer that can perform good printing on transfer paper with low smoothness.

Prior Art In order to perform good printing on transfer paper with low smoothness, it is necessary to smooth the transfer paper prior to printing, and various proposals have been made.

For example, in the method described in Japanese Patent Application Laid-Open No. 131259, transfer paper is moistened and passed between a pair of rollers to apply pressure, thereby improving the smoothness of the transfer paper.

However, since the relative speed between the roller and the transfer paper is 0 at the contact point, the fibers of the transfer paper deform only in the vertical direction, making it difficult to increase smoothness through plastic deformation.

Purpose The purpose of the present invention is to improve the above-mentioned problems, increase the smoothness of transfer paper, and provide a printer that can perform good printing even on transfer paper with low smoothness. .

Structure To achieve the above object, the printer of the present invention has means for smoothing the transfer paper by contacting and moving over the transfer paper supported by the platen, and the smoothing means The feature is that the transfer paper is smoothed before printing.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the outside N! of a printer in one embodiment of the present invention.
FIG.

The printer of this embodiment includes a transfer paper 1, a platen 2, a scanning table 3. Ink cartridge 4. Pressure member 5. Support member 6. It includes a solenoid 7 and a thermal head 9.

An ink cartridge 4° and a smoothing device are mounted on the scanning table 3. This scanning table 3 is
Printing is performed by the thermal head 9 parallel to the platen 2, running from the left side to the right side of the transfer paper l, and the above-mentioned smoothing 9
11 is located in front of the thermal head 9 in the direction in which the thermal head 9 prints, and is placed on the transfer paper 1 in advance.
Smoothing is performed by applying pressure.

FIG. 2 is an explanatory diagram of a smoothing device in a printer according to an embodiment of the present invention.

The smoothing device in this embodiment includes a pressure member 5°, a support member 6. Consists of a solenoid 7 and a spring 8.

Since the pressure member 5 presses its edge against the transfer paper 1 supported by the platen 2, a material having excellent abrasion resistance such as full bending, glass, ceramic, etc. is used. Further, the pressure member 5 is fixed to a support member 6, and is pressurized and released by a solenoid 7 and a spring 8.

In this way, by moving the edge of the pressure member 5 against the transfer paper l, high pressure can be obtained and the fibers of the transfer paper can be deformed more greatly than the rolling method, which promotes smoothing. be able to.

Effects According to the present invention, by providing a relative speed between the pressure member and the transfer paper, it is possible to deform the fibers of the transfer paper to a greater extent, and it is possible to deform the fibers of the transfer paper to a greater extent, thereby making it possible to produce good results even on transfer paper with low smoothness. It becomes possible to perform printing.
