Memory card adaptor

摘要

A card tray to be mounted to a memory card can make the memory card mountable in a card slot for memory cards conforming to standards different from those to which the memory card conforms. The card tray has a main body and a recessed mount section. The recessed mount section is formed such that the holder of a second memory card can be mounted to one of the major surfaces of the main body. A memory-card-mounted body is produced when the second memory card is mounted to the recessed mount section. The card tray is configured such that, when the first memory card is placed on the memory-card-mounted body with the left and right edges thereof aligned with each other, the contact pieces of the first memory card and the contact pieces of the second memory card have longitudinally overlapping parts and transversally overlapping parts as viewed from above.
