Electronic device having electronic card connector

An electronic device with an electronic card connector comprising:

• a housing, the housing having:
• a supporting wall with a first outer surface and a first inner surface, the inner surface of the supporting wall being defined by a plurality of supporting wall inner surface edges;
• and
• a plurality of peripheral sidewalls extending away from the supporting wall at two or more of the supporting wall inner surface edges, with one of the peripheral side walls defining a first through hole and a second through hole;
• wherein, the supporting wall and plurality of peripheral sidewalls define an accommodating space, with each of the peripheral side walls having a second inner surface facing the accommodating space and a second outer surface opposite to and substantially parallel to the second inner surface;
• and
• wherein, the first though hole and the second through hole are positioned on the through-holed peripheral wall close to the supporting wall and extend from the second outer surface of through-holed peripheral wall to second inner surface of the through-holed peripheral wall;
• a movable tray having a defined space for receiving the electronic card;
• a second geared rack having a lower surface slidably coupled to the first inner surface of the supporting wall, the second geared rack having an upper surface, opposite to and substantially parallel to the lower surface of the second geared rack, the upper surface of the second geared rack being coupled to the movable tray;
• a rotatable cylinder gear attached to the first inner surface of the supporting wall and meshing with gears of the second geared rack;
• and
• a first geared rack slidably position along the first through hole with a portion of the first geared rack extending from the accommodating space through the second first through hole, the first geared rack having gears meshing the rotatable cylinder gear;
• wherein, when the first geared rack is slide along the second through hole, the cylinder gear is engaged and turned and the cylinder gear engages the second geared rack moving the movable tray.
