Definitions

  • This invention relates to a method of forming an embossed character on a portable-type medium in the form of a card such as an IC card.
  • an embossing apparatus which is called an embosser has been used to form an embossed character on an IC card.
  • FIG. 6 shows a process of forming an embossed character by the use of such a conventional embosser.
  • the embosser comprises a male die 10 provided with a projection in the form of a certain character and a female die 9 provided with a recess in the form of the same character into which the projection of the male die 10 is fitted.
  • an IC card 1 is placed between the male die 10 and the female die 9, and then both the dies 9 and 10 are pressed against the IC card 1 so that the projection of the male die 10 cuts into the plastic substrate of the IC card 1.
  • the plastic substrate is deformed so as to have an embossed character 8-1 thereon.
  • Figures 3a and 3b show a multi-functional IC card with a display.
  • the IC card 1 is provided with a display section 3-1 and input/output keys 7-2 on its rear side as shown in Figure 3b, and also provided with a magnetic stripe 9 , embossed characters 8-1 , and external terminals 3-6 through which electric signals are input or output on its front side, as shown in Figure 3a.
  • FIG. 5 shows a sectional view of an IC card of this type.
  • the IC card 1 comprises an IC module 3 disposed between metallic panels 5 and 6 , and the spaces between the upper panel 5 and the IC module 3 and between the lower panel 6 and the IC module 3 are filled with adhesive 4 .
  • To the upper panel 5 is attached a rear face panel 7 provided with key contacts 7-1 , and to the lower panel 6 is attached a front face panel 8 on which embossed characters 8-1 are previously formed.
  • a frame 2 To the upper panel 5 is attached a rear face panel 7 provided with key contacts 7-1 , and to the lower panel 6 is attached a front face panel 8 on which embossed characters 8-1 are previously formed.
  • FIG 4 is a perspective view of the above-­mentioned IC module 3 , which comprises an LCD display device 3-1 , an LSI chip 3-3 , the external terminals 3-­6 , a sheet-type battery 3-2 , a key contact pattern 3-5 , and the like, all incorporated into a substrate 3-4 .
  • the size of the IC module 3 is substantially the same as that of the IC card. This means that the electronic components are embedded in the entire region of the IC card.
  • embossed characters are to be formed on any portion of such an IC card by means of a conventional embosser, the embedded components will surely be damaged by the stress applied by the embosser.
  • embossed characters are previously formed on the front face panel alone and then the front face panel with the embossed characters is used in the assembly of the IC card.
  • embossed characters are formed in the production process of an IC card, so that the issuer of an IC card should select the characters to be formed before the production process starts.
  • the method of forming an embossed character on an IC card of this invention comprises the steps of: applying a viscous resin, which adheres to the surface of the IC card and hardens when exposed to ultraviolet light, onto the surface of the IC card while forming a desired character with said resin; and projecting ultraviolet light onto said surface of the IC card so as to harden said resin applied in the form of said desired character.
  • the step of applying said resin to the surface of said IC card is performed by the use of a resin-application device comprising a discharging unit with a nozzle for discharging said resin, an X-Y table which is disposed below said nozzle and moves in the directions of X and Y with respect to said nozzle, and a control unit which controls said discharging unit and said X-Y table.
  • a resin-application device comprising a discharging unit with a nozzle for discharging said resin, an X-Y table which is disposed below said nozzle and moves in the directions of X and Y with respect to said nozzle, and a control unit which controls said discharging unit and said X-Y table.
  • the IC card includes an IC module comprising a substrate into which an LCD display device, an LSI chip, external terminals, a sheet-type battery, a key contact pattern, and the like, are incorporated.
  • the size of said IC module is substantially the same as that of said IC card, said IC module being interposed between a pair of metallic panels.
  • each of said metallic panels is provided with a face panel attached thereto.
  • the invention described herein makes possible the objectives of (1) providing a method of forming an embossed character on an IC card, in which an embossed character can be formed without applying any stress on the IC card so that the electronic components embedded therein are not damaged, thereby improving the reliability of the IC card; (2) providing a method of forming an embossed character on an IC card, in which an embossed character can be formed without interfering with the inside structure of the IC card, so that the embossed character will not impose any restriction on the layout of the electronic components embedded within the IC card; (3) providing a method of forming an embossed character on an IC card, in which an embossed character can be formed on a completely-manufactured IC card with a display, so that it is not necessary to form any embossed characters during the production process of the IC card, resulting in a reduced production cost of the IC card, and so that an embossed character can be formed on the IC card at any time after the production of the card; (4)
  • a method of forming an embossed character on an IC card of this invention comprises two processes.
  • One is a resin-application process in which a viscous resin that can adhere to the surface of an IC card and will harden when exposed to ultraviolet light is applied to the IC card while a desired character is being formed with the resin, and the other is a UV radiation process in which the resin thus applied in the form of the desired character to the surface of the IC card is irradiated with ultraviolet light so as harden.
  • Figure 2 shows an apparatus for forming an embossed character on an IC card, which is used in the method of this invention.
  • the apparatus comprises a resin-application device including a discharging unit 12 , an X-Y table 11 and a control unit 13, for performing the above-mentioned resin-application process, and also comprises a UV radiation device 14 for performing the above-mentioned UV radiation process.
  • a viscous resin is contained in the discharging unit 12 which includes a pump for discharging the resin through the nozzle 12-1 with a fixed pressure for a predetermined period of time according to a discharge signal delivered from the control unit 13 .
  • This construction is known in the prior art.
  • the nozzle 12-1 faces an IC card 1 which is temporarily fixed on the X-Y table 11 so that the resin discharged from the nozzle 12-1 can be applied to the surface of the IC card 1 .
  • the X-Y table 11 can be horizontally moved in the directions of X and Y (the direction X is parallel to a pair of parallel sides of the rectangular IC card, while the direction Y is parallel to another pair of parallel sides thereof and is perpendicular to the direction X).
  • the distance and direction in which the X-Y table 11 moves is determined by a movement signal delivered from the control unit 13 .
  • the control unit 13 is substantially the same as a control unit of a conventional numerically controlled machine. As described above, the control unit 13 controls the period in which the discharging unit 12 discharges the resin and also controls the distance and direction in which the X-Y table 11 moves, in such a manner that a desired character, letter or figure can be formed with the resin discharged onto the IC card 1 fixed on the X-Y table 11 .
  • the control unit 13 is provided with a plurality of programmed sequences of discharge and movement signals, and the like, each sequence corresponding to a character, letter, figure, etc. The user, selects the appropriate sequences corresponding to desired characters to operate the apparatus.
  • the X-Y table 11 is first moved so that the nozzle 12-1 is located just above the starting point of the figure "1" to be formed on the IC card 1 . Then, the pump of the discharging unit 12 is driven to discharge the resin through the nozzle 12-1 onto the surface of the IC card 1 . At the same time, the X-Y table 11 moves in the direction of Y so as to allow the resin to be applied in the form of a straight line along the direction of Y onto the surface of the IC card 1 .
  • the X-Y table 11 stops, followed by the suspension of the operation of the pump, which stops the application of the resin.
  • the resin in the form of a line of a predetermined length is applied to the surface of the IC card 1 , resulting in an embossed figure "1". Since the resin has viscosity, the resin thus applied has a fixed height from the surface of the IC card 1 .
  • the IC card 1 on which a desired character has thus been formed is then subjected to a UV radiation process by the use of the UV radiation device 14 , which comprises a UV lamp 14-1 , a reflecting plate 14-2 and a table 14-3 .
  • the IC card 1 on which the resin in the form of the desired character has been applied is temporarily fixed on the table 14-3 , and then exposed to ultraviolet light emitted from the UV lamp 14-1 .
  • the resin in the form of the desired character hardens.
  • the resin adheres to the surface of the IC card, there is very little possibility that the resultant embossed character will be separated from the card.
  • Figure 1 is a sectional view of a multi-­functional IC card with a display, on which embossed characters are formed by the method of the invention.
  • the IC card 1 comprises an IC module 3 disposed between two metallic panels 5 and 6 , and the spaces between the upper panel 5 and the IC module 3 and between the lower panel 6 and the IC module 3 are filled with adhesive 4 .
  • To the upper panel 5 is attached a rear face panel 7 provided with key contacts 7-1 , and to the lower panel 6 is attached a front face panel 8 .
  • Embossed characters 8-2 are formed on the surface of the front face panel 8 of the completely-manufactured IC card 1 by the method of the invention.
  • an embossed character can be formed without applying any stress on the IC card so that the electronic components embedded therein are not damaged, thereby improving the reliability of the IC card.
  • the embossed character thus formed does not interfere with the inside structure of the IC card, so that there is no restriction on the layout of the electronic components embedded within the IC card.
  • an embossed character can be formed on a completely-manufactured multi-functional IC card with a display, so that it is not necessary to form embossed characters during the production process of the IC card, resulting in a reduced production cost thereof. Moreover, since the the characters to be formed need not be selected before the production process of the IC card, embossed characters can be formed at any time after the manufacture of the IC card.
