FIG. 5 is a schematic diagram showing the main components of the hologram layer forming mechanism, which is provided in the card printer 1 as shown in FIGS. The card printer 1 includes, for example, a hopper unit 3 for stacking a large number of cards 2 such as personal identification cards (so-called ID cards), a magnetic recording mechanism unit 4, a printer unit 5, and a hologram layer forming mechanism unit 6. The stacker unit 7 is provided. The cards 2 stacked on the hopper unit 3 are pushed by the pressing plate 31 and supported by the rubber roller 32, and are fed one by one to the conveying roller 33 by the rotation of the rubber roller 32. The card 2 that has passed through the transport roller 33 comes into contact with a cleaning roller 34 having a surface made of silicon rubber or the like and is sent to the magnetic recording mechanism section 4.

The card 2 sent to the magnetic recording mechanism 4 is
The magnetic head 43 is fed by the transport rollers 41 and 42.
The magnetic data is recorded while moving while being in contact with. The transport rollers 41 and 42 are rotated in the forward direction to record information by the magnetic head 43, and are rotated in the reverse direction to check the read of the recorded data by the magnetic head 43, and then are passed through the turntable 44 and sent to the printer unit 5. . The card 2 which has been determined to be a recording error in the read check is stored in the stacker 45 by the rotation of the turntable 44.

The card 2 sandwiched between the transport rollers 51 of the printer unit 5 is supported by the moving stage 52 by the rotation of the transport rollers 51. Card 2 supported by stage 52
The image is transferred by the transfer ribbon 53 and the thermal head 54 whose heating is controlled, and is further sent to the hologram layer forming mechanism section 6 by the carrying roller 55.

The card 2 sent to the hologram layer forming mechanism portion 6 comes into contact with the transfer film 63 wound around the reels 61 and 62, and is supported by the heat roller 64 and the press roller 65. The heat roller 64 heats the card 2 and pressurizes it together with the press roller 65. The transfer film 63 is
It has the layer structure shown in FIG. 4, a protective layer P made of a mixture of acrylic resin and polyethylene or wax is formed on a base B of PET (polyethylene terephthalate), and a urethane layer is formed on the protective layer P. A hologram layer H made of a system resin is formed, a vapor deposition layer M made of zinc sulfide is formed on the hologram layer H, and a polyester adhesive layer A to be attached to the card 2 is formed on the vapor deposition layer M. ing. The transfer film 63 is heated and pressed by the heat roller 64 and the press roller 65, and then peeled from the card 2 by the peeling roller 66. The peeled card 2 passes through the transport roller 67 and is sent to the stacker unit 7. In the stacker unit 7, the cards 2 are sent by the carrying rollers 71 and stacked.

[0007]

However, in such a hologram layer forming mechanism of the conventional card printer, when the transfer film 63 is peeled from the card 2 by the peeling roller 66, the peeling speed and the heat roller 64 are separated. Although the rotational peripheral speed is matched, the transfer film 63 may be extended due to temperature, the card 2 and the transfer film 63
If the adhesive force of is too large, the peeling speed between the card 2 and the transfer film 63 may become slow.

[0008] Such a card 2 and transfer film 63
If the peeling speed of No. 1 and the peripheral speed at the contact point of the heat roller 64 and the press roller 65 do not match, as shown in FIG.
Occurs. In this band Hb, the light reflection angle is discontinuous, and the light reflection angles of the surrounding hologram layers are different.

By the way, the hologram layer H on the card 2
Forms a beautiful hologram image with a constant reflection angle of light, and thus greatly affects the appearance quality. Therefore, if a band Hb having a different light reflection angle is generated on the way, the card 2
However, there is a problem that the quality of appearance of the hologram layer H is deteriorated.

Therefore, it is an object of the present invention to disclose a hologram layer forming mechanism of a card printer which does not generate a band-shaped nonuniform portion in the hologram layer.

[0011]

In order to solve the above-mentioned problems, a hologram layer forming mechanism of a card printer of the present invention comprises a transfer film having a transferable hologram layer wound around a heatable heat roller, and the hologram layer Is supported by a press roller parallel to the heat roller, the transfer film and the card are superposed and sandwiched between the heat roller and the press roller, and the heat roller is heated while heating the heat roller. While rotating together with a press roller, in a hologram layer forming mechanism of a card printer that transfers the hologram layer of the transfer film to the card surface by pressing, in the card transport downstream side from the contact portion between the heat roller and the press roller. At a position longer than the length of the card in the longitudinal direction, At least a pair of upper and lower rotatable support rollers for sandwiching the card in a state of being adhered to the copying film are provided, and an interval shorter than the length in the longitudinal direction of the card on the downstream side of card transportation is provided from the pair of support rollers. A peeling roller for movably supporting the card against the pulling force for peeling the transfer film from the card is provided at the position.

[0012]

According to the hologram layer forming mechanism of the card printer of the present invention, from the position where the transfer film and the card are nipped by the heat roller and the press roller,
Since the distance to the position where the transfer film and the card are clamped by the pair of support rollers is longer than the length in the longitudinal direction of the card, when the front end of the card is clamped by the pair of support rollers, the heat roller and the press roller are The rear end of the card is separated from the sandwiching part of the card.

Therefore, during the process from the start of transfer to the completion of transfer by heating and pressing the card and the transfer film, the resistance to the progress of the card does not act on the leading end of the card, so the heat roller is used during the transfer process of the card. Since the pressing force and the rotating force between the press roller and the press roller are evenly applied, there is no possibility that unevenness will occur in the adhered state of the card and the transfer film. This prevents the hologram layer transferred to the card from being distorted in the longitudinal direction and prevents the hologram layer from having discontinuous band portions.

At the position where the peeling roller peels the transfer film from the card, at the time of peeling, even if the pulling force of the transfer film changes discontinuously due to the expansion of the film due to heat or the change in the adhesive strength between the card and the film. Since the pair of support rollers freely rotate according to the change, the card is not affected by the discontinuous change in the tensile force of the film.

Therefore, the hologram layer transferred to the card is not distorted, a hologram layer having a uniform film thickness is formed over the entire card, and the reflection angle of the light of the hologram image is kept constant. Will be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hologram layer forming mechanism of a card printer according to an embodiment of the present invention will be described below with reference to the drawings.

In the present embodiment, the general configuration of the card printer 1 is the same as that of the prior art except for the hologram layer forming mechanism section 10, and therefore those parts will be described with reference to the description of the prior art. . Here, the card 2 for transfer is a plastic card, but it may be a card made of paper. Characters and figures are printed on the surface of the card 2 before the hologram layer is transferred.

Hologram layer forming mechanism 10 of this embodiment
Is a heat roller 11, a press roller 12, support rollers 13 and 14, a guide roller 15, and a peeling roller 1.
6 and feed rollers 17 and 18. These rollers 11 to 18 are supported by bearings (not shown) attached to the chassis of the card printer 1. Further, the rollers 11 to 18 are provided in the chassis of the card printer 1 so as to extend in the vertical direction. The transfer film 63 has a layer structure as shown in FIG. 4, and is wound by reels 61 and 62 as shown in FIG. The transfer film 63 is the heat roller 11
And between the press roller 12 and the pair of support rollers 13 and 13 and between the pair of support rollers 14 and 14, and the peeling roller 16 changes the direction to wind the film. To the reel 62 side.

The heat roller 11 has a cylindrical shape with a heater inside and has a small frictional resistance on the peripheral surface.
A surface layer made of a heat-resistant polymer compound (eg, tetrafluoroethylene, polytetrafluoroethylene, perfluoroalkyl vinyl ether, polyamide, polyimide, polyethylene naphthalate, or a polymer thereof) is formed. Although the heater is not shown, the heating temperature can be controlled by controlling energization.

The press roller 12 extends in parallel with the heat roller 11, and quickly absorbs the heat of the heat roller 11 and further has a surface made of a polymer compound similar to that of the heat roller 11 so as to reduce frictional resistance. Have layers. The heat roller 11 and the press roller 12 are in contact with each other such that the card 2 and the transfer film 63 are in close contact with each other and can be pressed with an appropriate pressure.

A guide roller 15 extending parallel to the heat roller 11 is provided in the vicinity of the contact portion between the heat roller 11 and the press roller 12 and at a position biased to the heat roller 11 side. The guide roller 15 is provided at a position where the transfer film 63 contacts the card 2 at a shallow angle.

In the heat roller 11 and the press roller 12, the hologram layer H is attached to the surface of the card 2 by heating the heat roller 11 and pressing the press roller 12. Contact area C between heat roller 11 and press roller 12
The distance L1 from p1 to the contact portion Cp2 of the pair of supporting rollers 13 and 13 is set to be larger than the total length L2 of the card 2, and the pair of supporting rollers 13 and 13 is separated from the contact portion Cp2 by the distance L1. Is arranged in a position.

As a result, the card 2 and the transfer film 63 that have passed between the heat roller 11 and the press roller 12
Is temporarily suspended from the inside, so heat roller 1
The transfer film 63 and the card 2 sandwiched between 1 and the press roller 12 are not subjected to the force of pulling or pushing along the plane direction of the card 2 which causes the distortion of the hologram layer H. Therefore, a beautiful hologram image without distortion is transferred to the card 2.

The card 2 which has passed through the pair of supporting rollers 13 and 13 is again sandwiched by the pair of supporting rollers 14 and 14. The two sets of support rollers 13 to 14 can freely rotate in the forward and reverse directions, and can freely rotate by the winding force of the transfer film 63. The surfaces of the support rollers 13 and 14 are covered with elastic synthetic rubber or the like or slightly flexible plastic or the like to allow the input resistance in the longitudinal direction of the card 2. The supporting rollers 13 and 14 have a function of preventing distortion on the rear end side of the card 2 as much as possible when the transfer film 63 is peeled off by the peeling roller 16, and when the hologram image attached to the card 2 is peeled off. I try not to distort it as much as possible. Therefore, 2
The separation distance between the pair of supporting rollers 13 and 14 is the separation roller 16.
Is set so that the card 2 can be supported so as not to bend during the peeling process in which the transfer film 63 is peeled.

The peeling roller 16 is arranged in the vicinity of the carrying area of the card 2 which is carried from the contact position Cp1 between the heat roller 11 and the press roller 12 toward the carrying roller 18. The distance L3 between the position Cp3 where the peeling roller 16 and the transfer film 63 start to contact and the contact position Cp2 between the supporting rollers 13 and 13 is set to be shorter than the total length L1 of the card 2, and moreover, the supporting roller. Support rollers 14 and 14 are disposed between the contact position Cp2 of the rollers 13 and 13 and the contact position Cp3 of the peeling roller 16.

Therefore, when the peeling roller 16 is pulled upward by the winding force of the transfer film 63, the peeling roller 1 is resisted against the pulling force of the transfer film 63 upward.
6 presses the middle part of the card 2, and further the supporting rollers 13, 13 support the rear end part of the card 2. Transfer film 63
Since the support rollers 13 to 14 and the peeling roller 16 freely rotate with respect to the pulling force of the transfer film 63, only the pulling force of the transfer film 63 is applied to the card 2, and the pulling force does not change. Transfer film 63 is card 2
The surface of the hologram layer H appears smoothly.

A layer of a fluororesin-based polymer compound on the surface of the heat roller 11 may be formed on the surface of the peeling roller 16 so that the sliding friction resistance of the transfer film 63 is reduced.

The feed rollers 17 and 18 arranged on the downstream side of the peeling roller 16 convey the card 2 from which the transfer film 63 is peeled to the stacker section 7 side, and the length of the card 2 from the support roller 14 is increased. They are arranged close to each other at a position shorter than the length L1. The peripheral speed of the peripheral surface of the feed rollers 17 and 18 that presses the card 2 is set to be the same as the peripheral speed of the portion of the peeling roller 16 that comes into contact with the card 2. It is synchronized with the transport speed of. In addition, the feed rollers 17 and 18
Is rotated via a motor and a gear mechanism to convey the card 2 to the stacker unit 7, but a synthetic rubber having a soft surface (for example, butyl rubber, butadiene rubber, silicone rubber, etc.) to allow a change in the conveying speed of the card 2. Other synthetic rubber) has a surface layer made of.

Other configurations are the same as the conventional card printer 1.
Since the configuration is the same as that of 1, the description will be incorporated.

According to the hologram layer forming mechanism 10 of the card printer 1 of this embodiment, the hologram layer H which can be transferred is used.
The transfer film 63 having the above is wound around the heat-controllable heat roller 11, the card 2 on which the hologram layer 11 is transferred is supported by the press roller 12 parallel to the heat roller 11, and the transfer film 63 and the card 2 are superposed. A card printer that is sandwiched between the heat roller 11 and the press roller 12 and transfers the hologram layer H of the transfer film 63 onto the surface of the card 2 by applying pressure while rotating the heat roller 11 while heating and heating the heat roller 11. In the hologram layer forming mechanism, the card 2 is attached to the transfer film 63 at a position at a distance L1 longer than the length L2 in the longitudinal direction of the card 2 from the contact portion Cp1 between the heat roller 11 and the press roller 12. At least a pair of rotatable support rollers 13 and 1 which are nipped.
3 is provided, and at a position Cp3 at a distance L3 shorter than the length of the card 2 from the pair of supporting rollers 13 and 13,
Since the peeling roller 16 that movably supports the card 2 against the force of peeling the transfer film 63 from the card 2 is provided, when the front end portion of the card 2 is nipped by the pair of support rollers 13 and 13, the heat roller is provided. 11 and press roller 1
The rear end of the card 2 is separated from the sandwiched portion with the card 2.

Therefore, during the process from the start of transfer by the heating and pressurization of the card 2 and the transfer film 63 to the completion of transfer, no resistance is exerted on the leading edge of the card 2 against the advance of the card 2, so that the transfer of the card 2 is completed. During the process, the pressing force and the rotating force of the heat roller 11 and the press roller 12 are uniformly applied, and the card 2 and the transfer film 6
There is no risk of unevenness in the adhered state of No. 3. This prevents the hologram layer H transferred to the card 2 from being distorted in the longitudinal direction, and prevents the hologram layer H from having a discontinuous band portion.

At the position where the peeling roller 16 peels the transfer film 63 from the card 2, the peeling force of the transfer film 63 at the time of peeling is discontinuous due to expansion due to heat and a change in the adhesion strength between the card 2 and the film 63. Even if it changes, the pair of support rollers 13, 13, 14, 14 and the peeling roller 16 freely rotate according to the change, so that the card 2 is not affected by the discontinuous change in the tensile force of the film 63. . Moreover, when the transfer film 63 is peeled off by the peeling roller 16, the support roller 14 supports the intermediate portion of the card 2 remaining on the upstream side, and further the support roller 13 supports the upstream end portion of the card 2. Therefore, the occurrence of distortion of the card 2 is extremely reduced, and in this embodiment, the support roller 14 is disposed between the support roller 13 and the peeling roller 16 and is shorter than the length L1 of the card 2 from the support roller 14. The feed rollers 17 and 18 are arranged at a position close to each other, and the feed rollers 17 and 18 are disposed at
Since the card 2 is synchronized with the conveying speed of the card 3, even if the rear end of the card 2 passes the contact position Cp2 of the support rollers 13 and 13, the transfer film 63 is peeled from the card 2 without curving the card 2. it can. Therefore, the hologram layer H transferred to the card 2 is not distorted, the hologram layer H having a uniform film thickness is transferred over the entire card 2, and the reflection angle of the light of the hologram image is kept constant. You will be drunk.

As described above, according to the hologram layer forming mechanism 10 of the card printer 1, there is no fear that the hologram layer H transferred to the card 2 is distorted, and the hologram layer H has a uniform film thickness. Since the reflection state of the hologram image is also uniform, the yield of a card with a beautiful appearance quality can be significantly improved, and data is recorded in a predetermined pattern on the hologram image so that the hologram image on the card is exposed to light. When a data reading method of irradiating and optically reading the reflected light and the like is adopted, it is possible to create a card in which reading errors and the like are unlikely to occur.

[0034]

According to the hologram layer forming mechanism of the card printer of the present invention, there is no risk of distortion in the hologram layer transferred to the card, the thickness of the hologram layer is uniform, and the hologram image is reflected. Since the state is also uniform, the yield of a card with beautiful appearance quality can be significantly improved, and data is recorded in a predetermined pattern on the hologram image, and the hologram image on the card is irradiated with light and When a data reading method that optically reads reflected light or the like is adopted, a card that is less likely to cause reading errors can be created.
