Electronic device and ejection mechanism thereof

摘要

An electronic device comprises a casing, an electronic element, and an ejection mechanism. The casing has a receiving space and an opening. The ejection mechanism includes: a holder for holding and carrying the electronic element to pass through the opening to be exposed outside the casing; a first biasing spring biasing the holder to project outwardly from the opening; a stopping member rotatably pivoted to the casing and contactable with a projection of the holder; a second biasing spring biasing the stopping member to contact the projection, and having an elastic modulus greater than that of the first biasing spring; and a releasing member operable for driving the stopping member to detach from the projection.

1. An electronic device comprising:
a casing formed with a receiving space, an opening, and a through hole, said opening and said through hole being adapted for communicating said receiving space with the outside; an electronic element; and an ejection mechanism including
a holder slidably connected to said casing and located within said receiving space, said holder being used for holding said electronic element and including a projection, said holder being capable of carrying said electronic element to pass through said opening to be exposed outside said casing;a first biasing spring disposed within said receiving space and biasing said holder to project outwardly from said opening;a stopping member rotatably connected to said casing and located within said receiving space, said stopping member being located between said opening and said projection and being removably contactable with said projection;a second biasing spring disposed within said receiving space and biasing said stopping member to contact said projection, said second biasing spring having an elastic modulus greater than that of said first biasing spring; anda releasing member extending through said through hole and operable for driving said stopping member to pivot relative to said casing to detach from said projection.
