Abstract
Abstract A memory card is disclosed which has a card body ( 2 ) having a concavity ( 9 ) formed at the forward end thereof in the inserting direction and in which terminals ( 5 ) are disposed and projections ( 10 ) are formed between the terminals ( 5 ) to prevent the terminals ( 5 ) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
A memory card comprising: a substantially rectangular card body having first and second surfaces; electrical terminals disposed proximate an edge of said first surface and positioned in recesses that open to said first surface; a storage device disposed in said card body for storing data; a control circuit disposed in said card body for controlling writing data supplied from said terminals into said storage device and reading stored data from said storage device to said terminals; and said card body having four corners, three of which are of substantially the same shape and the fourth of which is of a different shape to prevent incorrect insertion of said memory card into a receptacle therefor.
Claim 2
Dependent Claim
114 words
A memory card comprising: a substantially rectangular card body having first and second surfaces; electrical terminals disposed proximate an edge of said first surface and positioned in recesses that open to said first surface; a storage device disposed in said card body for storing data; a control circuit disposed in said card body for controlling writing data supplied from said terminals into said storage device and reading stored data from said storage device to said terminals; and said card body having four corners, three of which are of substantially the same shape and the fourth of which is of a different shape to prevent incorrect insertion of said memory card into a receptacle therefor.
Claim 3
Dependent Claim
142 words
A memory card comprising: a substantially rectangular card body having first and second surfaces; electrical terminals disposed proximate an edge of said first surface; a storage device disposed in said card body for storing data; a control circuit disposed in said card body for controlling writing data supplied from said terminals into said storage device and reading stored data from said storage device to said terminals; said card body having four corners, three of which are of substantially the same shape and the fourth of which is of a different shape to prevent incorrect insertion of said memory card into a receptacle therefor; and wherein said terminals are offset from a center line of said rectangular shape toward a first longitudinal edge of said card body and said fourth corner is provided along a second, opposite longitudinal edge of said card body.
Claim 4
Dependent Claim
142 words
A memory card comprising: a substantially rectangular card body having first and second surfaces; electrical terminals disposed proximate an edge of said first surface; a storage device disposed in said card body for storing data; a control circuit disposed in said card body for controlling writing data supplied from said terminals into said storage device and reading stored data from said storage device to said terminals; said card body having four corners, three of which are of substantially the same shape and the fourth of which is of a different shape to prevent incorrect insertion of said memory card into a receptacle therefor; and wherein said terminals are offset from a center line of said rectangular shape toward a first longitudinal edge of said card body and said fourth corner is provided along a second, opposite longitudinal edge of said card body.
