The sliding portion 32 is formed at both edge portions of the heat generating head which does not substantially perform the thermal transfer action. The sliding portion 32 minimizes the frictional force during the rotation of the thermoelectric conversion unit 3, .

Since the width of the card c is usually about 54 mm, the sliding portion 32 is formed on both sides of the edge except for the ceramic base resin, which is typically coated with a ceramic resin having a low coefficient of friction.

At this time, the cylindrical body 31 is formed to have a thickness of about 0.2 mm, and the sliding portion 32 is formed to have a thickness of several tens to several hundred nanometers (nm) to minimize the formation of the step at the boundary with the central portion, As shown in Fig.

More specifically, the thermoelectric conversion tube 3 has an outer surface portion 35, an outer surface portion 35, and an outer surface portion 35, which are woven by weft (a) and warp (b) A connecting yarn 37 connected between the outer surface portion 35 and the inner surface portion 36 and a connecting yarn 37 connected between the outer surface portion 35 and the inner surface portion 36 so as to be spaced apart from each other by a weft yarn a and a warp yarn b, 35 and a coating layer 38 formed by coating a thermally conductive resin on the inner surface portion 36.

The thermoelectric conversion tube 3 may be formed by supplying inorganic fibers or organic fibers to a velveteen loom so that the thickness is approximately 0.2 mm.

At this time, the inorganic fibers can be selected and applied as long as they have a low thermal expansion coefficient in the range of -20 to 20 ppm / ° C in the longitudinal direction and the transverse direction. Typically, E-glass fiber, D- Glass fibers, and T (S) -glass fibers.

The organic fibers may be those having a coefficient of thermal expansion in the longitudinal and transverse directions ranging from -20 to 20 ppm / 占 폚 among wholly aromatic polyaramid fibers, polybenzoxazole fibers, liquid crystal polyester fibers, and PE fibers (polyethyene yarn) Can be selected and configured.

In order to minimize the thickness of the thermoelectric conversion tube, it is preferable to use a flat type yarn having a flat surface with a thin thickness of the fiber in cross section.

As described above, when the thermoelectric conversion tube 3 is formed in a multi-layer structure composed of the outer surface portion 35, the connecting yarn 37 and the inner surface portion 36, the connecting yarn 37 Can be absorbed and the damage or deformation of the heat generating head 2 or the card c can be prevented in advance and the space portion between the outer surface portion 35 and the inner surface portion 36 can be prevented from being damaged It is possible to maintain the heating temperature at a constant level, thereby improving the lamination quality and re-transferring quality.

Hereinafter, the operation of the secondary head device of the card printer according to the embodiment of the present invention will be briefly described.

First, as described above, the card is provided with a lamination device portion (not shown in Fig. 1) of a card printer for attaching a lamination patch of a transparent material to protect the printed surface printed on the surface, (Not shown, see Fig. 2) of a card printer for printing and printing a printed image on a card.

As shown in FIGS. 3 and 5, when the card printer is operated in the state that the above-described secondary head device is installed, the card c enters the upper surface of the conveying roller device 8, When the head driving device (not shown) disposed on the upper part of the apparatus is operated, the secondary head device is lowered.

When the secondary head unit is lowered in this manner, the heat generating head 2 is lowered, and the thermoelectric generating cylinder 3 is inserted into the outside of the heat generating head, so that the part of the thermoelectric generating cylinder 3 is in direct contact with the card surface Heat transfer action is performed.

More specifically, the thermal transfer cylinder 3 applies a pressing force to the surface of the card c placed on the conveying roller unit 8, and at the same time, the heat transferred from the internal heating element is applied to bond the lamination patch to the card surface Or the image printed on the intermediate transfer film (d) is printed on the card surface.

At this time, since the thermoelectric conversion cylinder 3 has flexibility, when it comes into contact with the surface of the card, it is deformed flat on the bottom surface of the heat generating head 2 to make surface contact while forming a fixation nip. The thermal transfer characteristics are improved and the joining and printing operation can be stably performed.

The rotating inertia force of the conveying roller unit 8 is applied to the thermoelectric conversion element 3 in the process of the completion of the bonding and printing operations as described above and the secondary head unit is lifted, The secondary head unit is lowered again and the above-described operation is repeatedly performed to perform the joining and printing operation. Since the thermoelectric conversion element 3 is guided by the cylindrical guide member 4, the thermoelectric conversion element 3 is stable and rotates without distortion.

In particular, as shown in Fig. 7, when the sliding portion 32 having a low coefficient of friction is formed at both edge portions of the thermoelectric conversion element 3, the frictional force is minimized because the sliding portion 32 is rotated around the sliding portion 32, It is possible to prevent a phenomenon that a specific part is deteriorated due to a rotation failure because the rotating operation of the using cylinder 3 is performed smoothly.

8, if the thermoelectric conversion element 3 is formed in a multi-layer structure composed of the outer surface portion 35, the connecting yarn 37, and the inner surface portion 36, It is possible to prevent the heat generating head 2 and the card from being damaged or deformed in advance and the space between the outer surface portion 35 and the inner surface portion 36 The heating temperature can be kept constant, thereby improving the bonding and printing quality.

As described above, the present invention is not limited to the above-described embodiment, but can be applied to a secondary head device of a card printer according to the present invention, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
