An electronic device includes a housing, a card holder, and a card holder mechanism. A sidewall of the housing defines a slot. A projection protrudes from the card holder. The card holder control mechanism includes a knob and a rotatable plate. The knob includes an operation portion and a connecting portion. The operation portion is external to the housing for operation, and the connecting portion is received in the housing and secured to the rotatable plate. When the knob is rotated from a first orientation to a second orientation, the rotatable plate is driven to rotate by the rotation of the knob. During the rotation of the rotatable plate, the rotatable plate resists the projection of the card holder to drive the card holder to move toward the slot until a portion of the card holder extends the housing. |
