Electronic card holder and electronic device using same

An electronic device, comprising:

• a housing comprising a bottom plate and a peripheral sidewall protruded from the bottom plate, and the peripheral sidewall defining a housing opening and a slide groove;
• and
• an electronic card holder comprising:
• a fixed member attachable to the bottom plate, the fixed member having a first side wall and a second side wall substantially parallel to and opposite the first side wall, the first side wall and the second side wall forming a defined receiving space, the defined receiving space having an opening;
• a tray configured to accommodate an electronic card usable with the electronic device, the tray slidably passing through the housing opening and the opening in sequence and further receiving in the defined receiving space, the tray having a first side outer surface parallel to the first side wall and a second side outer surface parallel to the second side wall;
• and
• a latching member attached to a sidewall of the first side wall opposite the receiving space, the latching member having a main body, a pressing portion extending from the main body away from the first side wall and further protruding out from the slide groove, and a latching portion protruding from the main body toward the defined receiving space;
• wherein, the sidewall defines a sidewall opening through which the latching portion may extend, and the tray defines a sidewall notch on the first side outer surface for receiving the latching portion;
• wherein, when the tray is engaged with the fixed member, the latching portion passes through the sidewall opening and is received in the sidewall notch;
• and
• wherein, the latching portion is driven to move away from the sidewall notch by an external pressure applied on the pressing portion of the latching member, the tray is thus disengaged with the fixed member.
