Abstract

A memory card socket has a plate-like antenna block having a coil-like secondary antenna which is opposed to an antenna incorporated in a memory card in a state where the memory card is attached to the card receiving portion. Openings as cavities are formed in portions of the antenna block inside of the coil of the secondary antenna. With this structure, it is possible to obtain a memory card socket having a compact and simple structure and having a non-contact communication function capable of preventing producing cost from increasing.

Claims

1. A memory card socket comprising

a case formed with a card receiving portion for receiving a thin plate-like memory card having a coil-like antenna, and

a slider which is held in the card receiving portion such that the slider can move forward and backward in an inserting/pulling-out direction of the memory card in association with a memory card inserted into the card receiving portion, in which

the memory card pushed into the card receiving portion is held on a deep side in the card receiving portion through the slider, wherein

the memory card socket further comprises a plate-like antenna block having a coil-like secondary antenna which is opposed to the antenna, and

a cavity is formed in a portion of the antenna block inside of a coil of the secondary antenna.

6. The memory card socket according to claim 1, wherein the antenna block can move forward and backward in an inserting/pulling-out direction of the memory card.

2. A memory card socket comprising

a case formed with a card receiving portion for receiving a thin plate-like memory card having a coil-like antenna, and

a slider which is held in the card receiving portion such that the slider can move forward and backward in an inserting/pulling-out direction of the memory card in association with a memory card inserted into the card receiving portion, in which

the memory card pushed into the card receiving portion is held on a deep side in the card receiving portion through the slider, wherein

the memory card socket further comprises a plate-like antenna block having a coil-like secondary antenna which is opposed to the antenna, and

a magnetic sheet is provided inside of a coil of the secondary antenna of the antenna block.

7. The memory card socket according to claim 2, wherein the antenna block can move forward and backward in an inserting/pulling-out direction of the memory card.

3. A memory card socket comprising

a case formed with a card receiving portion for receiving a thin plate-like memory card having a coil-like antenna, and

a slider which is held in the card receiving portion such that the slider can move forward and backward in an inserting/pulling-out direction of the memory card in association with a memory card inserted into the card receiving portion, in which

the memory card pushed into the card receiving portion is held on a deep side in the card receiving portion through the slider, wherein

the memory card socket further comprises a plate-like antenna block having a coil-like secondary antenna which is opposed to the antenna, and

the antenna block is provided with a magnetic sheet located between the secondary antenna and the antenna of the memory card.

4. The memory card socket according to claim 3, wherein the magnetic sheet is provided such as to cover an entire region of an inner side from at least an outer peripheral edge of the secondary antenna.

5. The memory card socket according to claim 3, wherein the magnetic sheet is a band-like sheet extending along a coil of the secondary antenna.

8. The memory card socket according to claim 3, wherein the antenna block can move forward and backward in an inserting/pulling-out direction of the memory card.

9. The memory card socket according to claim 4, wherein the antenna block can move forward and backward in an inserting/pulling-out direction of the memory card.

10. The memory card socket according to claim 5, wherein the antenna block can move forward and backward in an inserting/pulling-out direction of the memory card.
