Description

  The present invention relates to an electronic module built-in card having a display unit.

Conventionally, there has been a card incorporating a module having a display device (for example, Patent Document 1).
However, in the conventional card, a hole is provided in a resin (plastic) layer and a transparent material is embedded. For this reason, the conventional card is difficult to be aligned and manufactured.
In addition, the resin layer has a small thickness, and a base color corresponding to the design or the like may not be able to use a resin having a strong hiding power. In such a case, the conventional card may be seen through the module.
Furthermore, the conventional card is difficult to manufacture because the display device built in the card and the position of the transparent material are required to be aligned with high accuracy.
Furthermore, the conventional card is required to adjust the height of the surface of the resin layer and the surface of the transparent material in order to make the card surface smooth, and it is more difficult to manufacture.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings and the like.
FIG. 1 is a plan view and a cross-sectional view of a card 1 according to the first embodiment.
FIG. 1A is a plan view of the card 1.
FIG. 1B is a cross-sectional view of the card 1 (a cross-sectional view taken along line bb in FIG. 1A).
FIG. 1C is an enlarged cross-sectional view showing the vicinity of the window 50.
FIG. 2 is a plan view illustrating the internal structure of the card 1 according to the first embodiment.
Note that FIG. 1B shows the edge 32a of the white print layer 32 protruding inward in order to clarify the layer structure, but in practice, as shown in FIG. 1C. The upper transparent substrate 30 is printed.

In the embodiment, a view in which the normal direction of the card upper surface 1a (ticket surface) is the vertical direction (stacking direction) Z and the card upper surface 1a is viewed is referred to as a plan view as appropriate. In the plan view, the longitudinal direction of the card 1 is defined as the left-right direction X, and the lateral direction is defined as the vertical direction Y. The shape in the plan view is appropriately referred to as a planar shape.
In each drawing, the size and the like of the vertical direction Z, the vicinity of the window 50, etc. are exaggerated as appropriate for the sake of clarity.
As shown in FIG. 1, the card 1 is a card having a thickness of about 0.8 mm. The card 1 has a function of generating an authentication password (so-called one-time password), but is not particularly limited to this function.

First, the electronic module 10 built in the card will be described.
As shown in FIG. 2, the electronic module 10 includes electronic components such as a substrate 11, a display unit 12, a button 13, a battery 14, and an IC chip 15.
The substrate 11 is a rigid or flexible type printed wiring board.
The display unit 12 is a display device that displays a one-time password. The display unit 12 is, for example, an electronic paper display or a liquid crystal display. The display unit 12 is mounted on the substrate 11. The display unit 12 is connected to the substrate 11 by a cable 12a.
The button 13 is a push button. The button 13 is, for example, a dome switch or the like mounted on the substrate 11. The button 13 outputs operation information to the IC chip 15.

The battery 14 is a member that supplies power to the display unit 12 and the IC chip 15 of the electronic module 10. The battery 14 is connected and fixed to the substrate 11 by a connection terminal 14a.
The IC chip 15 is a control device that controls the electronic module 10. The IC chip 15 is mounted on the substrate 11. The IC chip 15 is driven by power supplied from the battery 14. The IC chip includes a storage device (not shown) that stores a control program for controlling the processing of the electronic module 10.

The operation of the electronic module 10 will be described.
When the user presses the button operation range 30b (see FIG. 1A) on the card upper surface 1a, the IC chip 15 generates a one-time password based on the output of the button 13, and this one-time password. Is displayed on the display unit 12.
Although detailed description is omitted, as another configuration, a contact terminal, a loop antenna, and the like may be provided to communicate with an external device (card reader).

The configuration of the card 1 will be described.
As shown in FIG. 1, the card 1 includes an upper transparent substrate 30 on the upper side Z <b> 2 of the frame body 21, and includes a lower transparent substrate 20 on the lower side Z <b> 1 of the frame body 21. These layers are bonded with an adhesive or the like.
The frame body 21 is a layer that accommodates the electronic module 10. The frame body 21 is filled with an adhesive or the like, and the adhesive or the like holds the electronic module 10.

The upper transparent substrate 30 is made of a transparent or translucent material having translucency.
On the upper transparent substrate 30, a magnetic stripe 30a, a silver concealment print layer 31 (silver-based concealment print layer), a white print layer 32 (white print layer), and an upper pattern print layer 33 are provided as print layers. ing. The silver concealment printing layer 31, the white printing layer 32, and the upper pattern printing layer 33 are provided in order from the lower side Z1.

  The magnetic stripe 30 a is provided immediately above the upper transparent substrate 30. In the plan view, the magnetic stripe 30 a is provided in a strip shape in the left-right direction X. Information on bank account numbers and the like are recorded in the magnetic stripe 30a. This information can be read using a reader (not shown).

  The silver concealment printing layer 31 is provided by silk printing or the like directly on the upper transparent substrate 30 and the magnetic stripe 30a. The silver concealment print layer 31 is a silver print layer. The ink of the silver hiding printed layer 31 has a sufficient hiding power that does not allow light to pass through. For this reason, the electronic module 10 and the magnetic stripe 30a are concealed by the silver concealment printing layer 31, and are designed to make it difficult for a viewer to visually recognize the card upper surface 1a.

  The white printing layer 32 is provided by silk printing or the like immediately above the silver hiding printing layer 31. The white print layer 32 is a white print layer. The white print layer 32 changes the color of the upper pattern print layer 33 to a desired color. In other words, when the upper pattern print layer 33 is provided on the silver hiding print layer 31, the color of the pattern may appear different due to the silver color of the silver hiding print layer 31. The white printing layer 32 can conceal the silver color of the silver hiding printing layer 31 and color the upper pattern printing layer 33 in a desired color.

The upper pattern print layer 33 is provided immediately above the white print layer 32 and is disposed on the uppermost surface of the card 1. The upper pattern print layer 33 is formed, for example, by pressing and transferring a transfer foil provided on PET. The upper surface of the upper pattern print layer 33 may have a mirror shape or a mat shape.
The pattern printed on the upper pattern print layer 33 is observable from the card upper surface 1a, and has information such as characters, symbols, and figures. In the button operation range 30b, “press” is printed to indicate the operation position to the user.

The lower transparent substrate 20 is formed of the same material as the upper transparent substrate 30.
The lower pattern print layer 41 is provided directly below the lower transparent substrate 20. The lower pattern print layer 41 is provided by transfer or the like, similar to the upper pattern print layer 33. Note that the lower pattern print layer 41 may include a concealment layer similar to the silver concealment print layer 31 or the like so that the electronic module 10 or the like can be concealed when a viewer observes the lower surface of the card.

The card 1 is manufactured by manufacturing the printed lower transparent substrate 20 and the upper transparent substrate 30 in advance, laminating them on the lower side Z1 and the upper side Z2 of the frame body 21, and laminating them.
An example of the thickness of each layer of the card 1 is as follows.
Printing layer on upper transparent substrate 30: 1 to 5 μm
Upper transparent substrate 30: 100 μm
Frame 21: 450 μm
Lower transparent substrate 20: 100 μm
Underprint printing layer: 1-5 μm
Thus, the card | curd 1 can reduce the curvature accompanying lamination by setting it as the same layer structure up and down via the frame 21, and making it the same thickness.

The form of the window part 50 is demonstrated.
As shown in FIG. 1, the window part 50 is provided in an area corresponding to the display part 12. The viewer can see the display content of the display unit 12 through the upper transparent base material 30 inside the window unit 50.
The window 50 is formed by removing the silver hiding print layer 31, the white print layer 32, and the upper pattern print layer 33 so that they are not partially printed.
The edge of each printing range is the order of the white printing layer 32 (printing range A32), the silver concealment printing layer 31 (printing range A31), and the upper pattern printing layer 33 (printing range A33) from the inside of the window 50.
For this reason, the printed layer around the window 50 is observed as follows.
The edge portion 32 a of the white print layer 32 is exposed to the inside so as to form the edge portion of the window portion 50. The reason why the white color of the white print layer 32 is exposed in a frame shape is, for example, to meet a design requirement.
As shown in FIG. 1B, in the range B1, the silver concealment print layer 31 exists on the lower side Z1 of the white print layer 32, and does not exist in the inner range. For this reason, in the exposure range B2 of the white print layer 32, the white color may change between the range B1 where the silver color of the silver concealment print layer 31 can be seen through in a frame shape and the inside thereof.
However, even in this case, the exposure range B2 of the white print layer 32 is as small as about 1 mm, for example. Further, in this small width, there are three edges (the edge of the white print layer 32 (inner boundary), the edge of the silver concealment printing layer 31, and the edge of the upper pattern print layer 33 (outer boundary)). Are arranged consecutively. For this reason, the appearance of this white color change is inconspicuous. For this reason, even if a viewer observes the window part 50 periphery, there is no sense of incongruity.

The upper pattern print layer 33 is disposed on the white print layer 32 until the window portion 50 is closest. For this reason, the upper picture print layer 33 can develop a desired color up to the window 50.
The silver hiding print layer 31 is not exposed around the window 50. As described above, even if the silver concealment printing layer 31 is seen through, there is no sense of incongruity.

  In addition, since the printing edge part around the window part 50 changes in steps in this way, the card | curd 1 is not conspicuous even if there is a printing shift. Thereby, the card | curd 1 can reduce the positional accuracy at the time of printing, and can improve manufacturing efficiency.

As described above, the card 1 according to the present embodiment may be printed on the upper transparent substrate 30 and provided with the window portion 50 in order to make the display unit 12 visible and conceal the electronic module 10. So it is easy to manufacture. Moreover, since the silver concealment printing layer 31 is provided, the electronic module 10 can be sufficiently concealed.
Furthermore, the card 1 can develop a desired color up to the window 50 and the manufacturing efficiency can be improved.
Further, since the card 1 is formed by providing the window portion 50 with a printing layer on the upper transparent base material 30, the periphery of the window portion 50 can be smoothed, and the hole processing to the upper transparent base material 30 is necessary. Absent. Thereby, manufacturing efficiency can further be improved.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the following description and drawings of the respective embodiments, the same reference numerals or the last part (the last two digits) are assigned the same reference numerals for the same functions as those of the second embodiment described above, and are duplicated. Description is omitted as appropriate.
FIG. 3 is a plan view and a cross-sectional view (a diagram corresponding to FIG. 1) of the card 201 of the second embodiment.
Note that FIG. 3B shows the edge portion 233a of the upper picture print layer 233 projecting inward in order to clarify the layer structure, but actually, as shown in FIG. In addition, it is printed on the silver concealment printing layer 231.
The card 201 of the second embodiment is obtained by changing the printing range around the window 250 from the first embodiment, and other configurations are the same as those of the first embodiment.

The edge of the printing range around the window 250 is the order of the silver concealment printing layer 231 (printing range A231), the upper pattern printing layer 233 (printing range A233), and the white printing layer 232 (printing range A232) from the inside of the window 250. It is.
For this reason, the printed layer around the window 250 is observed as follows.
The edge part 231a of the silver hiding printed layer 231 is exposed to the inside so as to form the edge part of the window part 250. The reason why the silver color is exposed in the frame shape (see FIG. 3A) is, for example, to meet a design requirement.
The white print layer 232 is not exposed around the window portion 250.
In the upper pattern print layer 233, in the range B201, the white print layer 232 does not exist on the lower side Z1, and thus the silver color of the silver concealment print layer 231 may be seen through in a frame shape. Even in this case, the width of the frame shape is sufficiently small (for example, the width of the range B201 is within about 1 mm), and the edge portion 231a of the silver concealment printing layer 231 is located immediately inside. The shaped part is inconspicuous. For this reason, even if a viewer observes the window part 250 periphery, there is no sense of incongruity.

With the above configuration, the card 201 of this embodiment has the same effects as those of the first embodiment.
In addition, when the ticket surface (upper pattern print layer 233) has a dark color design such as black, it may be required to conceal the white color around the window portion 250 so as not to be noticeable. Even in such a case, it is possible to hide the white print layer 232 with the upper picture print layer 233 while hiding the electronic module 10 with the silver mask print layer 231.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
FIG. 4 is an enlarged sectional view showing the vicinity of the window 50 of the card 301 of the third embodiment.
In 3rd Embodiment, the mat | matte part 360 which has an unevenness | corrugation was provided in the white print layer 332 upper surface exposed around the window part 50, and the pattern print layer 333 upper surface. For example, the mat portion 360 may be provided by providing irregularities on a press plate used for card manufacture and shaping the card upper surface.
Thereby, even if the silver color of the silver concealment printing layer 331 in the range B301 is transparent, the card 301 can be more inconspicuously blurred, and even when there is a printing shift, it can be further inconspicuously blurred.
Note that the mat portion 360 of the present embodiment may be provided on the card 201 of the second embodiment. Also in this case, the same effects as in the present embodiment can be obtained.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
FIG. 5 is a plan view and a cross-sectional view (a diagram corresponding to FIG. 1) of the card 401 according to the fourth embodiment.
In FIG. 5B, in order to clarify the layer configuration, the thickness of the printed layer is increased and shown to have a space between layers, but actually, as shown in FIG. Such a large space does not occur, and the interlayer (hatched portion) is filled with an adhesive or the like.
The card 401 is provided with an upper pattern print layer 433, a white print layer 432, and a silver hiding print layer 431 in this order on the lower surface of the upper transparent substrate 430. The card 401 is not provided with a magnetic stripe on the upper surface side, and it is not necessary to conceal this. For this reason, the card 401 has a printing layer disposed on the lower surface of the upper transparent base material 430.
As in the first embodiment, the stacking order of the print layers is the silver concealment print layer 431, the white print layer 432, and the upper design print layer 433 in order from the lower side Z1.

The printed content of the pattern print layer 433 is observed through the upper transparent substrate 430.
The mode in which the window 450 is observed is almost the same as that in the first embodiment.
However, in the card 401, since the upper pattern print layer 433 is formed on the lower surface of the upper transparent substrate 430, the distance between the upper pattern print layer 433 and the display unit 12 in the vertical direction Z is shortened. For this reason, when the inside of the window part 450 is observed, the card 401 can improve the sense of unity of the upper picture print layer 433 and the display part 12 and can improve the texture.

  As described above, the card 401 can improve the texture when the inside of the window 450 is observed. Moreover, since the printing layer is arrange | positioned on the lower surface of the upper transparent base material 430, the card | curd 401 can suppress the contamination of a printing layer.

  Note that the configuration in which the print layer is disposed on the lower surface of the upper transparent base material 430 as described above may be applied to the first to third embodiments. Also in this case, the same effects as in the present embodiment can be obtained.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
FIG. 6 is a plan view and a cross-sectional view (a diagram corresponding to FIG. 1) of the card 501 of the fifth embodiment.
In the card 501 of this embodiment, the white printing layer 32 (see FIG. 1) is deleted from the first embodiment.
The upper pattern print layer 533 has a silver design. For this reason, even if the upper pattern print layer 533 is directly printed on the silver concealment print layer 531 without providing the white print layer 32, the desired pattern can be developed.

  In the periphery of the window portion 550, the edge portion 531a of the silver hiding print layer 531 is the innermost side, and the edge portion 533a of the upper pattern print layer 533 is observed on the outer side. In this case, since the design of the upper picture print layer 533 is silver, there is no sense of incongruity even if the viewer observes the window 550 and the surroundings.

As described above, the card 550 of this embodiment can reduce the cost by deleting the white print layer when the design of the upper picture print layer 533 is silver.
Note that the card 550 of the present embodiment may be modified as in the fourth embodiment, and the upper picture print layer 533 may be provided on the lower surface of the upper transparent base material 530. Also in this case, the same effect of suppressing fouling as that of the fourth embodiment is obtained.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made as in the modifications described later, and these are also included in the present invention. Within the technical scope. In addition, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. It should be noted that the above-described embodiment and modifications described later can be used in appropriate combination, but detailed description thereof is omitted.

(Deformation)
(1) In the first to third and fifth embodiments, the upper picture print layer and the lower picture print layer are exposed. However, the present invention is not limited to this. For example, an oversheet layer (thickness of about 60 μm), which is a transparent protective layer, may be provided on these surfaces. Thereby, the stain | pollution | contamination of an upper design print layer and a lower design print layer can be suppressed.

(2) In the embodiment, the example in which the lower base material is a lower transparent base material having translucency has been described, but the embodiment is not limited thereto. The lower substrate may be an opaque substrate such as white. In this case, the color of the lower pattern print layer can be expressed more accurately.
