Abstract

In a card-shaped memory having an IC module, a circuit board having integrated circuits thereon is provided in a card body. A plurality of circuit patterns are provided on the board. First ends of the patterns are connected to the integrated circuits. The second ends are disposed on one side of this board. A plurality of contacts are provided. The base ends of the contacts are connected to these circuit patterns. The leading ends are placed in connection holes in the card body. A holding member holds a plurality of the contacts together.

Claims

1. A card-shaped memory having an IC module comprising:

a card body (11)

connection holes (11b) provided on the side face of said card body;

a board (13) provided in said card body, and on which integrated circuits are arranged;

a plurality of circuit patterns (CP), first ends of said circuit patterns being connected to said integrated circuits, and second ends of said circuit patterns being disposed on one side of said board;

a plurality of contact means (15), leading ends of said contact means being placed in said connection holes and not extending beyond said body, and base ends of said contact means being respectively connected to said circuit patterns; and

holding means (16) laid on one side of said board holding said plurality of contact means together.

2. A card-shaped memory having an IC module comprising:

a card (11);

a board (13) provided in said card body, and on which integrated circuits are arranged;

first contact means (15a-15n) provided in said card body, and connected to said integrated circuits, said first contact means further being for connecting to first connector means of an external device, for data transfer;

second contact means (15o) provided in said card body, said second contact means protruding farther than said first contact means, and being for connecting to grounded second connector means of the external device;

a conductive member (12) provided on the surface of said card body; and

connecting means comprising a conductive spring (20) for electrically connecting this conductive member to said second contact means.

3. A card shaped memory having an IC module, comprising:

a card body (11) having connection holes provided at a side section thereof;

a board (13) having an integrated circuit provided on and within said card body;

first contact means (15a-15n) connected at a base end to the integrated circuit and having a free forward end located within a corresponding connection hole to allow data transfer;

second contact means (15o) having a base end mounted on said board and a free forward end extending beyond the first contact means, said second contact means being locatd within a corresponding connection hole;

a conductive member (12) provided on a surface of said card body; and

third contact means (20) for electrically connecting said conductive member to said second contact means.

4. The card shaped memory according to claim 3, wherein said first and second contact means are held by a holding means situated along one side section of said board.

5. The card shaped memory according to claim 3, wherein said integrated circuit is comprised of a static random access memory.

6. The card shaped memory according to claim 3, further comprising:
