Abstract:
1. An electronic device providing card holder access, comprising: a housing comprising a sidewall and a bottom, the sidewall defining a slot, and the bottom defining a through hole; a card holder comprising a top surface and a bottom surface opposite to the top surface, the top surface defining a recessed receiving space to receive an electronic card, a projection protruding from the bottom surface; and a card holder control mechanism comprising a knob, an elongated rotatable plate, and an elastic element, the knob comprising an operation portion and a connecting portion, the operation portion being external to the housing, the connecting portion extending through the through hole and secured to an intermediate portion of the rotatable plate, one end of the elastic element being connected to the rotatable plate, and an opposite end of the elastic element being connected to the bottom of the housing, the knob configured for being manually operated to rotate between a first orientation and a second orientation, the rotatable plate jointly rotatable with the rotation of the knob between a first position where the knob is in the first orientation, the elastic element is in an original natural state, the rotatable plate is spaced apart from the projection, and the card holder is entirely received within the housing, and a second position where the knob is in the second orientation, the elastic element is stretched, and the rotatable plate resists the projection and pushes the card holder to move toward the slot until a portion of the card holder extends out of the housing through the slot, a resilient elastic force provided from the stretched elastic element drives the rotatable plate and the knob to respectively return to the first position and the first orientation if an external force exerted on the knob disappears.
