Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a memory card with a case, in which a memory card equipped with an IC memory is housed in a case, and the external terminals of the memory card are covered.

Memory cards, which have IC chips mounted on thin plates such as plastic, have a larger storage capacity than conventional magnetic cards and cannot be easily counterfeited, so they are used as identification cards, credit cards, games, etc.
It is promising as an educational card, etc., and various proposals have been made.

(Prior art) This type of memory card has an IC chip mounted thereon, and an IC board having external terminals connected to the IC chip buried in a recess formed in a card base.
It is known that the surface of the IC board and the surface of the card base are fixed and integrated by thermocompression bonding or adhesive so that they are substantially flush with each other.

However, since the external terminals of this memory card are exposed to the outside, the external terminals are easily soiled when the card is handled, and there is also a risk that the external terminals may be peeled off due to external force.

Therefore, a case is molded by injection molding of synthetic resin such as ABS resin or polypropylene resin, and a storage section with a size approximately equal to the width, length, and thickness of the memory card is formed in the case. However, it was troublesome to put the memory card in and take it out from the case, and there was also a risk of accidentally dropping the memory card from the case.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and it forms a concave groove that does not contact the external terminal of the memory card from the opening of the housing part to the deep part of the case. At the same time, a long hole along the memory card storage direction is formed in at least one side of the case having a storage portion whose size is approximately equal to the width, length, and thickness of the memory card, and the long hole is formed in the memory card. A protrusion is provided at a position corresponding to the protrusion, and the memory card can be stored in the storage part of the case via the protrusion, thereby protecting the external terminal of the memory card and improving ease of handling.

(Example) Hereinafter, the specific structure of the present invention will be explained based on the example shown in FIGS. 1 to 3.

FIG. 1 is a perspective view showing an embodiment of a memory card with a case of the present invention, FIG. 2 is a cross-sectional view taken from FIG. 1, and FIG. 3 is a cross-sectional view taken from FIG.

In FIG. 1, A is a memory card A, and B is a case. Reference numeral 1 is an IC board, which is made of glass epoxy or polyimide, and has a number of external terminals 13 on the top surface for connection to devices such as computers, and a ROM, etc. on the bottom surface.
1 chip such as EPROM, EEPROM, etc.
2-chip EPROM etc. and microprocessor
An IC chip 12 is molded and mounted. Also, on the bottom surface of the board 11, there are many printed circuit boards 1.
4 are provided, and the IC chip 12 is connected to each printed wiring 14 and connected to the printed wiring 1.
4 is connected to each external terminal 13 on the top surface of the board 11 through a through hole (not shown) penetrating the board 11 at the end of the board 11, and the IC chip 12
is connected to the external terminal 13 via printed wiring 14.

The IC board 1 is embedded and fixed in a recess formed in a memory card A made of synthetic resin such as polyvinyl chloride or ABS resin so that the external terminal 13 is almost flush with the surface of the memory card A. There is.

On the other hand, B is a case, and has a storage part 2 with dimensions approximately equal to the width W1, length L1, and thickness T1 of the memory card A, and one side of the case B has a storage part 2 extending in the storage direction of the memory card A. A long hole 3 along the line is bored. On the other hand, memory card A has the slot 3 above.
A convex portion 4 is provided at a position corresponding to the position of the convex portion 4.
The memory card A can be freely stored in the storage section of the case B through the holder.

As shown in FIGS. 2 and 3, the storage section 2 has a groove 5 that does not contact the external terminal 13 of the memory card A from the storage opening of the case B to the inner part of the case B. It is possible to prevent the terminal 13 from being rubbed by the inner surface of the storage section.

The groove 5 may be formed by cutting out a dimension T2 larger than the thickness T1 of the card A over a predetermined width W2.

Although the groove 5 is illustrated as being formed only on the upper surface of the storage portion, it is not limited thereto and may of course be provided on both the upper and lower sides.

(Effects of the invention) The present invention has a long hole along the memory card storage direction in at least one side of the case, which has a storage part approximately equal in size to the width, length, and thickness of the memory card. The card is provided with a protrusion at a position corresponding to the elongated hole, and the memory card can be stored in the storage part of the case through the protrusion, so when the memory card is not in use, the external terminal of the memory card can be connected to the case. This protects the external terminals by covering them, and also prevents the external terminals of the memory card from coming into contact with an external device such as a computer by pushing the memory card out of the case through the protrusion when using the memory card. In addition, the external terminals of the memory card are formed with contact-free grooves from the storage opening to the back of the case, so when the memory card is stored in the case, the external terminals can be easily handled by the inner surface of the case. It has the advantage of being able to prevent rubbing.
