Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a memory card with a built-in IC (integrated circuit) chip.

Memory cards with built-in IC chips have a larger storage capacity than conventional magnetic cards and cannot be easily counterfeited, so they are promising as identification cards, credit cards, game cards, educational cards, etc., and various proposals have been made. ing.

(Prior art and its problems) This type of memory card consists of a card body that has an IC chip and an external terminal connected to the IC chip, but since the external terminal is exposed to the outside, when handling the card, The terminals are easily soiled, the external terminals may be peeled off by external force, and there is a risk that the card may malfunction or become inoperable when connected to an external device such as an external computer or video game device. Therefore, there has been a need for a memory card that is easy to handle and that can reliably protect the external terminals.

(Means for Solving the Problems) The present invention has been devised in view of the above conventional problems, and includes a card body having an IC chip and an external terminal connected to the IC chip, and a card body that houses the card body. A long hole is formed along the storage direction of the card body on one side of the case, and a sliding protrusion that penetrates the card body is provided at a position corresponding to the position of the long hole, while the other side of the case A through hole is drilled in the
A locking protrusion is passed through the through hole, a return spring material is disposed inside the case to bias the case body in the direction of entering the case, and the sliding protrusion is operated from the outside to move along the elongated hole. When the external terminal of the card body is exposed from the case after being moved, the engaging protrusion at the end of the sliding protrusion engages with the through hole, presses the locking protrusion, and causes the engaging protrusion to engage with the through hole. The card body can be moved in and out of the case by removing it and storing the card body in the case, and when using a memory card, the sliding protrusion can be operated from the outside to move it along the long hole of the case. Push the card body out of the case to expose the external terminals of the card body and connect it to an external device such as a computer or video game. The external terminal of the memory card is housed inside to reliably prevent the external terminal of the memory card from becoming dirty or peeling off due to external force.

(Example) Hereinafter, a specific configuration of the present invention will be described based on an example shown in FIGS. 1 and 2.

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

In Figures 1 and 2, 1 is a card body,
Substrate 1 made of glass epoxy or polyimide, etc.
IC such as ROM, EPROM, EEPROM on the top surface of 1
Chip 12 is molded and mounted.
Further, a large number of external terminals 13 are provided at the end of the card body 1 for connection with external devices such as a computer or a video game device, and the IC chip 12 is connected to the external terminals 13 through printed wiring (not shown).
is connected to.

A memory card is constructed by housing the card body 1 in a case 2 consisting of an upper half body 2a and a lower half body 2b. The upper half body 2a and the lower half body 2b may be manufactured by injection molding synthetic resin such as polyvinyl chloride or ABS resin.

A long hole 21 along the storage direction of the card body 1 is bored in the upper half 2a of the case 2.
A sliding protrusion 3 passing through the card body 1 is provided at a corresponding position. On the other hand, a through hole 22 is formed in the lower half 2b of the case 2, and the locking protrusion 4 is passed through the through hole 22.

5 is a return spring material which connects the card body 1 to the case 2.
It is biased in the direction of inward movement.

When the external terminal 13 of the card body 1 is exposed, the engaging protrusion 31 at the end of the sliding protrusion 3 engages with the through hole 22 formed in the lower half body 2b, and the card body 1
is prevented from entering Case 2. Reference numeral 61 denotes a spring member that biases the engaging protrusion 31 to be pushed into the through hole 22.

In order to store the card body 1 in the case 2, the locking protrusion 4 is pushed against the biasing force of the spring member 61 that biases the locking protrusion 4 in the direction of protruding outside the case 2. When the engagement protrusion 31 of the protrusion 3 is disengaged from the through hole 22, the card body 1 is automatically housed in the case 2 by the return spring member 5.

To expose the external terminals 13 of the card body 1 from the case 2 again, the sliding projections 3 are operated from the outside and moved along the elongated holes 22. Then, the engaging protrusion 31 of the sliding protrusion 3 is pressed by the spring member 62 and engages with the through hole 22, so that the external terminal 13 of the card body 1 is exposed as shown in FIGS.

As shown in FIGS. 1 and 2, it is preferable to use spring members 61 and 62 to ensure reliable operation, but these are not always necessary.

In addition, the card body 1 includes an IC chip 12 and
The present invention can also be applied to card bodies 1 of other configurations as long as they are equipped with external terminals 13 connected to IC chips 12. Further, although the external terminal 13 is shown in the figure on one side of the end of the memory card, it is of course applicable to a case where the external terminal 13 is placed on both sides.

(Effects of the invention) Since the present invention has the above structure, when using a memory card, the card body can be pushed out of the case with a simple operation of operating the sliding protrusion from the outside and moving it along the long hole of the case. By exposing the external terminals of the card body, you can connect it to an external device such as a computer or video game, and by simply pressing the locking protrusion, you can store the card body in the case. This has the advantage that it is possible to reliably prevent the external terminal from becoming soiled or peeling off due to external force.
