EXAMPLES Prior to the description of the examples, label attachment on the IC card to be processed will be described with reference to FIG. Labeling methods include a method using a hot melt adhesive sheet (a) and a method using a label with a hot melt adhesive (b).

As shown in the figure, in the case of (a), a hot-melt adhesive sheet 31 is arranged between the label 3 and the card body 5 for alignment, and the heating tool 30 controlled to a predetermined temperature is used for the label 3. When the hot melt adhesive sheet 31 is melted by applying heat from the side and the heating tool 30 is released and cooled, the hot melt adhesive is solidified and the labeling is completed.

In the case of (b), as shown in the drawing, a label 32 with a hot melt adhesive is prepared, aligned, and the heating tool 30 controlled to a predetermined temperature is labeled 32.
When applied by applying heat from the side to melt the hot-melt adhesive, and when the heating tool 30 is released and cooled, the hot-melt adhesive solidifies and labeling is completed.

By the way, the hot melt adhesive contains 12
Many of those that melt at around 0 ° C are used, and the higher the heating temperature, the faster the bonding process. However, I in the IC card
C is resin-sealed at 160 to 180 ° C. at the time of manufacturing, and if the heating temperature exceeds this temperature, the IC may be damaged. Therefore, the temperature of the heating tool 30 is 180
It is necessary to control the temperature so that it does not exceed ℃. For the same reason, the heating roll and the heating / adsorption tool in each of the examples described below are controlled to a predetermined temperature not exceeding 180 ° C.

An IC with the label 3 attached in this way
The card is exfoliated by the devices of the following examples.

(Embodiment 1) FIG. 1 shows an embodiment 1 "I".
It is a figure which shows the structure of the label peeling apparatus of C card.

In FIG. 1, reference numeral 1 is a resin roll sheet having a large tensile strength, and a thermosetting adhesive A.
2 is pre-coated. 3 is a label to be peeled off, 4
Is a hot melt adhesive B used in any of the above-mentioned methods, 5 is an IC card body, and 6 is a heating roller controlled to a predetermined temperature. Reference numeral 7 is an IC (not shown)
It is a carrier that holds the card and carries it in the direction of arrow C. As the restraint means, a mechanism that mechanically presses the end of the IC card or a so-called vacuum chuck that sucks the lower surface of the IC card can be used. The roll sheet 1 is configured to be wound in the direction of the arrow D at substantially the same speed as the transport body 7.

With the above structure, when the right end of the IC card comes under the heating roller 6, the thermosetting adhesive A.
Since 2 is adhesively cured and the hot melt adhesive B.4 is melted, the right end of the label 3 is adhered to the roll sheet 1 and pulled, and peeling starts. As the carrier 7 moves, the label 3 is sequentially heated to the left and peeling progresses, and the left end of the IC card passes under the heating roller 6 to complete the peeling.

In this way, the label can be easily peeled off when the IC card is reused.

Since the label processed in this embodiment is attached with a hot melt adhesive, it is difficult to peel it off manually. Even if it can be peeled off manually, the temperature of the heating means cannot be controlled, so there is a high possibility that the IC card will be damaged. In addition to this, the illegal function of the IC card can prevent unauthorized modification of the IC card. it can.

(Embodiment 2) FIG. 2 shows an embodiment 2 "IC
It is explanatory drawing of "label peeling apparatus of a card."

In FIG. 2, reference numeral 20 denotes a heating / adsorption tool which is controlled to a predetermined temperature and which is adsorbed by the negative pressure of the passage shown by the broken line leading to the heating surface. As shown in the figure, the label-equipped IC card prepared by any of the above-mentioned methods is heated by applying a heating / adsorption tool 20 of a predetermined temperature from the label 3 side, and is separated from the IC card body 5 while adsorbing the label 3 Peel off. The lower surface of the IC card is fixed by a vacuum chuck (not shown) so that the IC card body 5 does not float up. The residue of the adhesive 4 remaining on the IC card body 5 is removed by a so-called hot brush made of Kevlar (brush heated by a heater) which is a heat resistant fiber to obtain a recycled product.

In this way, the label can be easily peeled off also in this embodiment.

(Modification) Although each of the above embodiments relates to the peeling of the label of the IC card, the present invention is not limited to this, and a sheet form such as a label attached to various articles. It can be carried out in the form of peeling the member. At this time, the heating / sucking surface of the heating / sucking tool needs to have a shape that matches the shape of each article.

Further, the heating / suction tool used for the peeling process can be used also as the heating tool at the time of attaching the label.

[0031]

As described above, according to the present invention,
A sheet-like member such as a label that is difficult to peel off manually can be easily peeled off from the main body, and the main body can be reused.
