Adapter, memory card, and memory card module

A memory card structured enabling it to be housed in an adapter, wherein:

• the adapter has an adapter body for defining a space for housing the memory card and a write protect mechanism for setting whether to enable or disable writing of data into the memory card;
• the write protect mechanism is formed so as to protrude from a side surface on one side of the adapter body into an inner space of the adapter body;
• the memory card comprises
• a memory portion to which data can be written, and
• a terminal portion electrically connected to the memory portion;
• and
• a notch portion is formed on a side surface on one side of the memory card so as to conform to a shape of the write protect mechanism of the adapter.

A memory card module comprising:

• an adapter to be attached to a memory card for changing an external shape such that it can be inserted into a memory card insertion section of specific type equipment;
• and the memory card, wherein:
• the adapter comprises
• an adapter body for defining a space for housing the memory card,
• a write protect mechanism including a write enable/disable setting member which is slidable with respect to the adapter body, and
• a terminal portion located in the adapter body, which is formed so as to be electrically connected to a terminal portion of the memory card when the memory card is housed in the adapter body;
• the write protect mechanism sets whether to enable or disable writing data into the memory card in accordance with the position of the write enable/disable setting member;
• the memory card housed in the adapter body comprises
• a memory portion to which data can be written, and
• a terminal portion electrically connected to the memory portion;
• and
• a notch portion is formed on a side surface on one side of the memory card so as to conform to a shape of the write protect mechanism of the adapter.
