Ejecting device for storage card

An ejecting device for use in a body of an electronic device for receiving and ejecting a storage card, comprising:

• a first housing fixed to the body;
• a second housing fixed in the first housing, the second housing defining an opening for allowing insertion of the storage card thereinto;
• an ejecting member received in the second housing, the ejecting member movable between a retaining position where the storage card is entirely retained by the ejecting member within the second housing and a releasing position where the storage card is released and ejected out by the ejecting member from the second housing;
• a first spring member received in the second housing and configured to apply a force on the ejecting member to push the ejecting member to move from the retaining position toward the opening of the second housing, thereby the ejecting member ejecting the storage card out of the second housing;
• an engaging member movable between a first position where the engaging member engages with the ejecting member when the ejecting member is in the retaining position and a second position where the engage member disengages from the ejecting member when the ejecting member is in the releasing position;
• an electromagnet configured to apply a magnetical attraction force to the engaging member to move the engaging member from the second position to the first position;
• a circuit board;
• a switch button electronically connected to the circuit board, the switch button configured to generate an ejection signal in response to a user's operation thereupon;
• and
• a processor mounted on the circuit board and configured to execute a program to save data in the storage card in response to the ejection signal, the processor further configured to control the electromagnet to pull the engaging member to disengage the ejecting member during a preset period after the execution of the program is finished.
