  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same referential mark is attached | subjected to the component which exhibits the same or similar function through all the drawings, and the overlapping description is abbreviate | omitted.

(Embodiment 1: Information medium corresponding to claims 1 and 2)
FIG. 1 is a plan view schematically showing Embodiment 1 of an information medium according to the present invention.
In the information medium 1, a contact portion 12 having electrical conductivity and a reaction portion 13 having electrical conductivity are formed on a base material 11. The contact portion 12 and the reaction portion 13 are connected by a conductive portion 14 so as to be conductive.

  The relationship between the contact portion 12 and the reaction portion 13 and the conductive portion 14 is formed so as to be about twice or more when compared with the unit length of the conductive portion 14. That is, the width or area of the contact portion 12 and the reaction portion 13 is formed to be twice or more that of the conductive portion 14.

  The reason is that, as a characteristic of the projection type capacitive reader, it does not recognize that there is no capacitance change over a certain area. This is because only the position is recognized and the conductive portion 14 is not recognized.

  The contact part 12, the reaction part 13, and the conductive part 14 are not particularly specified as long as they are substances having electrical conductivity. The contact part 12, the reaction part 13 and the conductive part 14 are formed by performing metal plating on the base material 11 and then etching the metal plating, and printing conductive ink on the base material 11. Thus, there is a method for producing a pattern.

  The conductive ink may have a sheet resistance value of 100Ω / □ or less, and a pattern can be produced using a screen printing method or the like.

  Therefore, it is desirable to make the width or area of the contact portion 12 and the reaction portion 13 to be twice or more that of the conductive portion 14. Therefore, if the reaction part 13 has an electric conductivity and has a size of φ2 mm or more, the conductive part 14 is produced with a width of half or less. However, if the width of the conductive portion 14 is 2 mm or more, the capacitance change occurs in the conductive portion 14 itself, and the position of the conductive portion 14 is recognized. Therefore, the width of the conductive portion 14 is not less than 2 mm. Don't be.

(Embodiment 2: Information medium corresponding to claim 3)
FIG. 2 is a plan view schematically showing Embodiment 2 of the information medium according to the present invention.
In the information medium 1, a non-reactive portion 15 is newly provided on a base material 11 in addition to a contact portion 12 having electrical conductivity, a reaction portion 13, and a conductive portion 14.

  The non-reacting part 15 is not in a state where it can be electrically connected to the contact part 12 and the conductive part 14. As a result, the projected capacitive reader cannot be recognized because the non-reactive portion 15 does not cause a change in capacitance.

  These non-reacting parts 15,... Have substantially the same shape as the reacting part 13 and have a so-called dummy role of the reacting part 13.

(Third embodiment of information medium: corresponding to claim 4)
FIG. 3 is a plan view schematically showing Embodiment 3 of the information medium according to the present invention.
In the information medium 1, the reaction unit 13 and the non-reaction unit 15 are not in a conductive state, but are regularly arranged in the vertical and horizontal directions. It can be said that the reaction part 13 and the non-reaction part 15 are regularly arranged in the same manner in the arrangement of FIG.

  At this time, if the distance between the reaction parts 13 adjacent to each other, for example, the distance between the reaction parts 13a and 13b is too close, the coordinates cannot be recognized due to the capacitance change. There is.

  Although it depends on the performance of the projection-type capacitive reader, the distance between the adjacent reaction units 13 (13a and 13b) is 5 mm or more, preferably 10 mm or more is easier to recognize the reaction position of the reaction unit 13. .

(Embodiment 4: Information medium corresponding to claims 5 and 6)
FIG. 4 is a plan view schematically showing Embodiment 4 of the information medium according to the present invention.
This information medium 1 is similar to FIG. 3 in terms of pattern, but when visually observed, it appears that both the reaction part 13 and the non-reaction part 15 are connected by the conductive part 14, and the two are distinguished. I can't.

  However, the non-reactive portion 15 is not electrically connected to the conductive portion 14 as can be seen by actually expanding a part of the information medium 1 as shown in FIG. That is, the insulating part 16 is provided between the conductive part 14 and the non-reacting part 15. If this insulating part 16 is given the same color as the conductive part 14, it cannot be visually discriminated.

Next, FIGS. 6 and 7 are cross-sectional views taken along line XX of the information medium 1 shown in FIG.
FIG. 6 is a sectional view showing another embodiment of the information medium 1 (corresponding to claim 7).

  The information medium 1 is provided with a raised portion 17 in each lower layer portion of the reaction portion 13 and the non-reaction portion 15 which are conductive portions in cross section. As a result, the reaction part 13 and the non-reaction part 15 are in a raised state than the other parts.

  Therefore, by adopting a configuration in which the reaction unit 13 and the non-reaction unit 15 are raised, the reaction unit 13 can easily come into contact with the touch panel surface of the projection capacitive reader, and the conductive pattern (information pattern) can be read. Stabilize.

  FIG. 7 is a sectional view showing still another embodiment of the information medium 1 (corresponding to claim 8).

  This information medium 1 is configured such that the reaction portion 13 and the non-reaction portion 15 are raised from the other portions, as in FIG.

  Accordingly, in the information medium 1 shown in FIG. 7 as well, the reaction unit 13 can easily come into contact with the touch panel of the projection capacitive reader as in FIG. 6, and the reading of the conductive pattern (information pattern) is stabilized. .

8 to 11 are diagrams for explaining an embodiment of the information medium reading method according to the present invention.

The state which made contact is shown. When the finger 21 is brought into contact with the contact portion 12 of the information medium 1, the charge held by the finger 21 that is a part of the hand 2 is moved to the reaction portion 13.

  Therefore, when the reaction unit 13 is brought into contact with the touch panel 31 of the reading device 3 as shown in FIG. 10 with the finger 21 in contact with the contact unit 12 of the information medium 1, the charge remaining in the reaction unit 13. Reacts to the touch panel 31, and the reading device 30 recognizes the position of the reaction unit 13 via the touch panel 31.

  The information medium 1 has a plurality of reaction portions 13..., But if the reader 30 recognizes the positional relationship of the touched reaction portions 13 as the read pattern 33, the read pattern 33 is linked. The read image 32 can appear.

  Next, FIG. 11 is a schematic diagram after the reading device 30 has read the pattern of the reaction unit 13 of the information medium 1. A read image 32 appears on the touch panel 31, and this read image 32 appears. A reading pattern 33 also appears. The read pattern 33 is in a mirror-surface relationship with the pattern of the reaction unit 13 of the information medium 1. Further, the reading pattern 33 may not be displayed on the screen.

Several specific examples will be described below.
