Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention 1 relates to a portable UJ function diagram storage medium having an electric circuit formed therein, such as an IC card or a memory card.

1. Technical costs of the invention and its problems 1. When creating this type of portable storage medium, it is better to use a rigid module in the form of a co-dip than to use a flexible module. 5. Due to its nature, it is easy to install.

Therefore, rigid modules are increasingly being applied to this type of portable storage medium.

However, when using a rigid module, if it is used for a long period of time under conditions where mechanical external edges such as bending are applied, the rigid module may fall off from the base material. There is a growing risk of

[Object of the Invention 1] The present invention has been made in view of the above, and its object is to provide a portable storage medium with improved mechanical strength.

[Summary of the Invention 1] In order to achieve the above object, the portable storage medium of the present invention has a configuration in which a coin chip-shaped rigid module equipped with a locking member is attached to a base material.

Example of invention C] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view showing the main structure of a portable storage medium according to an embodiment of the present invention.

This portable storage medium is constructed by forming a hole 3 as shown in FIG. 2 in a tortoise so that a rigid module 2 falls into a base material 1 made of vinyl chloride, and inserting carbon into the hole 3 as shown in FIG. A rigid module 2 in which a recess 4 having an inner diameter larger than the bottom opening size is formed is placed, and a base material 1 and a helical ball module 2 are thermocompression bonded using a ferro temporary 5 as shown in FIG. As shown in Figure 1, concave e! A configuration is obtained in which the softened base material 1 has entered the inside of I4. Note that 6 is an air vent, 7 is a Ti packaging, and 8 is an external connection terminal.

Therefore, in this portable storage medium, the structure of the mounting portion of the rigid module 2 is made strong without using adhesive.

Further, after mounting the rigid module 2 on the base material 1, the base material 1 can be covered with a cover sheet 9 in which contact holes for external connection terminals 8 are formed, as shown in FIG. .

Further, as shown in Fig. 6 (A), after covering the surface of the rigid type module 2 with a cover sheet 9, as shown in Fig. 6 (B), the surface of the rigid module 2 was covered with the cover sheet except for the holes 3. A rigid type module 2 can be attached to the base material 1 to create a portable storage medium as shown in FIG. Matching the printing on the material 1 surface cover sheet simplifies production.

FIG. 7, FIG. 8, and FIG. 9 are diagrams showing the structure of a portable storage medium according to another embodiment of the present invention.

FIG. 7 (Δ) shows a rigid module 11 in which a convex portion 12 with a rotation stopper 13 is formed at the center of the periphery.

The same figure (C) shows the rigid type module 31 which formed the four part 32 in the center of a periphery, and formed the rotation stop part 33 in the lower part.

A base material 1 in which holes 14, 24, 34 corresponding to these rigid modules 11, 21, 31 are formed is shown in FIGS. 8(A), (B), and (C).

From this relationship, the hole 14 as shown in Figure 9 (A)
The rigid module 11 can be attached to the base material 1 only when the base material 1 on which it has been formed is curved.

In addition, as shown in FIG.
The rigid module 21 can only be mounted on the base material 1 when it is curved.

In addition, as shown in FIG.
Rigid modules can only be installed when the is curved.

This makes it easy to install rigid modules, but
Since the rigid type module is fitted due to curvature, when such a configuration is adopted, measures must be taken to prevent the rigid type module from peeling off from the portable storage medium during use.

Therefore, as shown in FIG.
A slit 42 is formed near the rigid module 41 in the center of the base material 1 into which the module 1 is fitted.

In the case of this embodiment, when the base material 1 is bent by an external force, the position where the slit 42 is formed is particularly bent significantly.
The other portions of the base material 1 maintain good flatness, and therefore the remodule 41 is prevented from being detached from the base material 1 in a rigid manner υ1.

Further, as shown in FIG. 11, the slits may be replaced with 43, and in this case, the slits 42 in FIG.
Similarly to the case where 1111152 is formed, the rigid module 41 is prevented from being removed from the base material 1.

In addition, when the flexible type L Joule 51 is laminated in the base material 1 as shown in FIG.
By forming an IC chip, an excellent portable storage medium such as an IC chip can be produced. At that time, the first
Forming a plurality of slits 52 as shown in FIG. 3 is preferable from the viewpoint of protecting the portable storage medium since stress concentration on one slit 52 is avoided. It is also effective to form the rib h 52 into a curved shape as required.

From a different perspective, prevention of separation of rigid modules can be made effective.

For example, as shown in FIG. 14, the part that the bottom of the rigid module 61 inserted into the M shrine 1 comes into contact with is an elastic member 62, and this elastic member 62 is fixed to the rigid module 61 with an adhesive. ? do.

Note that double-sided adhesive tape can also be used as the adhesive.

In this case, even if the base material 1 is curved as shown in FIG. 15, the elastic member 62 will relieve the bending stress.

Furthermore, as shown in FIG. 16, even if a high-rigidity small piece Jff is laminated at the mounting portion of the rigid module 71 on the base material 1, the tax suppression effect of the rigid module 71 can be exerted.

Furthermore, as shown in FIG. 17, a rigid plate may be laminated on the base material 1 where the rigid module 81 is attached, the thickness of which becomes thinner toward the end. In this case, as shown in FIG. It also has the function of preventing loss (U) of the base material 1 when the base material 1 is curved.

[Effect of the Invention 1 As explained above, the portable storage medium to which the present invention is applied has improved mechanical strength, and therefore the range of applications is significantly expanded.
