A card printer is a device that prints letters and patterns on the surface of various cards such as ID cards, ID cards, and employee cards. When a card is supplied from the card supply device, the card printer is located above the printing ribbon supplied onto the printing surface of the card. The print head is driven to perform printing.

The printed card is attached with a lamination patch (meaning a coating film) made of a transparent material in order to protect the printed surface such as an image, pattern, text, and the like printed on the surface. The lamination patch is placed on the surface and applied by thermal attachment.

For example, the instantaneous direct heating type card lamination device developed by the present applicant and disclosed in Korean Patent Registration No. 10-1253307 has been proposed.

As shown in FIG. 1, the card lamination apparatus includes a lamination head 140 and a lamination head 140 that are instantaneously heated by the power applied and disposed on the transfer path of the card a to emit heat. Pressing down so that the lamination patch (b) is coated on the card (a), the head lifting means 150 for raising again when the coating is completed is provided.

The lamination head 140 has a structure in which a heating element 142, a heat dissipation member 143, and a temperature sensing unit 144 are installed inside the head case 141 formed in a rectangular columnar hexahedron shape.

On the other hand, the card printer is not printed by directly contacting the printing ribbon on the plastic card, but the printing process by the printing ribbon on the intermediate transfer film is performed, and then the image printed on the intermediate transfer film through the lamination process (re-transfer) There has been proposed a reprint card printer which is laminated and printed on the substrate.

For example, a "transfer color transfer printer of instantaneous direct heating", which is developed by the present applicant and disclosed in Korean Patent Registration No. 10-1308536, has been proposed as a retransmission card printer.

Referring to Figure 8, the secondary head device of the card printer according to a second modification of an embodiment of the present invention is a head case 1 is provided with a cylindrical rotating space 15, the heating head 2 is installed in the head case ), A cylindrical heat transfer cylinder (3) inserted into the circumference of the heat generating head and a cylindrical guide member (4) installed on the top of the heat transfer cylinder to guide the rotation operation, wherein the heat transfer cylinder (3) has a card surface. It is formed into a planar body having a multilayer structure in order to improve adhesiveness upon contact with, absorption of impact force, and resilience.

More specifically, the heat transfer cylinder 3 has an outer surface portion 35 and an outer surface portion 35 in which the cross-sectional structure is woven by the weft yarn a and the inclination b, as shown in the enlarged portion of FIG. An inner surface portion 36 woven by the weft yarn (a) and the inclined (b) to be spaced apart to the connecting portion 37, the outer surface portion (37) connected between the outer surface portion 35 and the inner surface portion (36) 35) and a planar body having a coating layer 38 formed by coating a thermally conductive resin on the inner surface portion 36.

In addition, the heat transfer cylinder 3 may be applied to a woven fabric by supplying inorganic fibers or organic fibers to the velvet loom to have a thickness of about 0.2 mm.

In this case, the inorganic fiber may be selected and applied as long as the fiber has a low coefficient of thermal expansion having a coefficient of thermal expansion in the longitudinal and transverse directions of -20 to 20 ppm / ° C., but typically E-glass fiber, D-glass fiber, NE- Glass fiber, T (S) -glass fiber can be applied.

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

First, as described above, the card may be attached to a lamination device portion of a card printer (not shown in FIG. 1) to attach a lamination patch of transparent material to protect the printed surface printed on the surface, or to the first printed intermediate transfer film. The printed image is mounted on a re-transfer portion (not shown in Fig. 2) of a card printer which is laminated and printed on a card.

3 and 5, when the card printer is operated in the state where the above-described secondary head device is installed, the card c enters the upper surface of the feed roller device 8, and in this state, the secondary head When the head driving device (not shown) disposed above the device is operated, the secondary head device is lowered.

When the secondary head device is lowered in this way, the heat generating head 2 is lowered, and since the heat transfer cylinder 3 is inserted into the outside of the heat generating head, the part of the heat transfer cylinder 3 is in direct contact with the card surface. Thermal transfer will be performed.

More specifically, the thermal transfer cylinder 3 bonds the lamination patch to the card surface by applying a pressing force to the surface of the card c mounted on the feed roller device 8 and applying heat received from the internal heating element. Or, the image printed on the intermediate transfer film (d) is printed on the card surface.

At this time, since the heat transfer cylinder 3 is flexible, when it comes into contact with the surface of the card, it is flatly deformed at the bottom of the heat generating head 2 to form a fixing nip so that the surface is brought into contact with each other. Thermal transfer characteristics have been improved, enabling stable bonding and printing.

Since the inertia force of the feed roller device 8 acts on the heat transfer cylinder 3 during the process of assembling and printing as described above and the secondary head device is raised, the rotation operation is performed to some extent, and then the controller Under the control of the secondary head device is lowered again and repeat the above-described operation to perform the bonding and printing operation. And, since the heat transfer cylinder (3) is guided by the tube guide member (4), it is stable and rotates without deformation.

In particular, when the sliding portion 32 having a low coefficient of friction is formed at both edge portions of the heat transfer cylinder 3, as shown in FIG. 7, the frictional force is minimized since the sliding portion 32 is rotated based on the sliding portion 32. Since the rotation operation of the use cylinder (3) is performed smoothly, it is possible to prevent the phenomenon that a particular part is deteriorated due to the poor rotation.

In addition, as shown in FIG. 8, when the heat transfer cylinder 3 is formed in a multilayer structure having an outer surface portion 35, a connecting yarn 37, and an inner surface portion 36, the heat transfer cylinder 3 is lowered together with the heat generating head 2. In the process, the portion of the connecting yarn 37 may be contracted to absorb impact force, thereby preventing damage and deformation of the heat generating head 2 or the card, and the space between the outer surface 35 and the inner surface 36. Since it performs the function of a thermal insulation chamber for storing the additional heat, it is possible to maintain a constant heating temperature to improve the bonding and printing quality.
