Abstract:
Ejecting mechanism for memory card, comprising:a seat cover connected with one side of a terminal seat, a support arm being pivotally disposed on a middle portion of the seat cover, one end of the support arm being bent to form a stop section, whereby when the memory card is inserted into the terminal seat, the stop section is pushed by the memory card to pivot the support arm, the other end of the support arm being formed with a projecting section, the seat cover being further formed with a protuberance beside the stop section, the seat cover being further formed with a swelling resilient abutting plate beside the projecting section in the pivoting path thereof, the protuberance serving to stop the support arm from pivoting, the resilient abutting plate serving to abut against the projecting section of the support arm to bend and lift the projecting section, the seat cover being further formed with a clamping sheath on one side of the resilient abutting plate; a press key seat which is fitted in the clamping sheath of the seat cover and connected with the seat cover, a projecting shaft being transversely disposed in one end of the press key seat, a hook being pivotally fitted on the projecting shaft, a curved resilient plate extending from one side of the projecting shaft to a middle portion of the press key seat to abut against the hook, a slope being formed in the middle portion of the press key seat and extending toward the other end thereof, an end section of the slope being formed with a stop section having an outward extending pin, a spring being fitted around the pin; and a press key having an extension section extending into the press key seat, a middle portion of the extension section being formed with a hollow section passing through the extension section from upper side to lower side thereof, the pin and the spring fitted therearound being received in the hollow section to resilient abut against the same, a guide channel being formed at an end section of the extension section beside the hollow section, whereby the hook is slidably inlaid in the guide channel to hook locating points thereof so that the press key seat and the press key can be extended or retracted to change the length, the slope of the middle portion of the press key seat serving to guide a corresponding portion of the press key, whereby when the press key seat and the press key are relatively retracted, the front end of the press key is simultaneously pressed downward so that when the memory card is inserted, the press key will not be ejected, when pressing the press key to extend the press key out of the press key seat, the front end of the press key is engaged with the projecting section of the support arm, whereby the support arm can be pushed and pivoted to make the stop section of the other end of the support arm reversely push the memory card and eject the memory card out of the terminal seat.
