Receiving apparatus and electronic device employing the receiving apparatus

An electronic device, comprising:

• a housing;
• and
• a receiving apparatus mounted in the housing, the receiving apparatus defining two states and switchable between the two states;
• comprising:
• a casing;
• a lid rotatably engaged in one side of the casing to open and close the casing;
• and
• the receiving apparatus further comprising a supporting portion and a transmission mechanism;
• the supporting portion engaged with a bottom of the casing for receiving an input and output interface;
• the transmission mechanism driving the supporting portion to rotate relative to the bottom of the casing by cooperation with the lid;
• wherein when the receiving apparatus is in a closed state of the two states, the lid covers the casing and the supporting portion is inclined relative to the bottom of the casing;
• when the receiving apparatus switches to an open state from the closed state, the lid rotates to open the casing and the supporting portion rotates relative to the bottom of the casing to be perpendicular to the bottom of the casing.
