Electronic device for recognizing erroneous insertion of card, and operating method thereof

摘要

An electronic device comprises a socket having a plurality of connection terminals that accommodates a card-type external device having a corner cut-out portion, a plurality of contact pads exposed on a surface of the card-type external device that are correspondingly connected to the connection terminals in response to insertion of the card-type external device into the socket. A detection unit detects erroneous insertion of the card-type external device into the socket in response to incorrect location of the cut-out portion during the erroneous insertion. A processor outputs a control signal in response to the detected erroneous insertion of the card-type external device.

主权项

1. An electronic device comprising:
a socket provided within the electronic device for receiving a card-type external device having a cut-out portion formed in a corner of the card-type external device; a detection unit for detecting erroneous insertion of the card-type external device in the socket, wherein external device wherein the detection unit includes: (i) a movable piece occupying the cut-out portion when the card-type external device is correctly inserted into the socket, and (ii) a fixed piece that electrically couples to the movable piece when the card-type external device is erroneously inserted into the socket; and a control unit configured to output a control signal in response to the fixed piece electrically coupling with the movable piece.
