Semiconductor device and a method of manufacturing the same
View Patent ↗On an adapter mounting portion 3 a having a projecting cross section which is formed on a cap 3 of a small-sized memory card 1, a recessed portion of an adapter 2 side is fitted so that both parts are formed as an integral unit in a replaceable manner. Accordingly, the small-sized memory card 1 can maintain the dimensional compatibility with respect to existing memory cards whereby the small-sized memory card 1 can be used also in equipment which is designed to cope with the existing memory cards.
1. A multi media card comprising:
a card body having a front surface and a rear surface opposite to said front surface, said card body having a first pair of opposed sides extending in a first direction and a second pair of opposed sides extending in a second direction substantially perpendicular to said first direction;
a plurality of external terminals formed on said rear surface of said card body and being arranged in a vicinity of one of said first pair of opposed sides of said card body; and
a groove for catching formed in said rear surface of said card body and being disposed in a vicinity of the other of said first pair of opposed sides of said card body and at a substantially central position between said second pair of opposed sides of said card body.
2. A multi media card comprising:
a card body having a front surface and a rear surface opposite to said front surface, said card body having a first pair of opposed sides extending in a first direction and a second pair of opposed sides extending in a second direction substantially perpendicular to said first direction; and
a plurality of external terminals formed on said rear surface of said card body and being arranged in a vicinity of one of said first pair of opposed sides of said card body;
wherein said card body has a first thickness defining a standard thickness of said multi media card,
wherein said card body has thinned portions at both end portions of the other of said first pair of opposed sides of said card body,
wherein said thinned portions have a second thickness thinner than said first thickness of said card body,
wherein said thinned portions are defined by recesses formed on both of said front and rear surface of said card body, and
wherein lengths of said recesses are different from each other in said second direction.
3. A multi media card according to claim 2 , wherein a length of said recesses on said front surface of said card body is longer than a length of said recesses on said rear surface of said card body.
4. A multi media card comprising:
a card body having a front surface and a rear surface opposite to said front surface, said card body having a first pair of opposed sides extending in a first direction and a second pair of opposed sides extending in a second direction substantially perpendicular to said first direction; and
a plurality of external terminals formed on said rear surface of said card body and being arranged in a vicinity of one of said first pair of opposed sides of said card body;
wherein said card body has a first thickness defining a standard thickness of said multi media card,
wherein said card body has thinned portions at both end portions of the other of said first pair of opposed sides of said card body,
wherein said thinned portions have a second thickness thinner than said first thickness of said card body, and
wherein side surface of said thinned portions are receded from said second pair of opposed sides of said card body toward an inside of said card body in a plan view, respectively.
