To provide a card supply mechanism performing secure card supply by improving separation actions among cards from each other and reducing loads applied on the lowest layer card to be delivered.

An eccentric cam 46 is rotated so as to take the maximum radius by driving a motor for rotating the eccentric cam 46, cards housed inside a card stacker in a stacked state in the vertical direction are lifted up by an inclined and stepped card abutment surface 14a of a movable member 14, the eccentric cam 46 is rotated so as to take the minimum radius by further driving the motor for rotating the eccentric cam 46, and one end is positioned on the inclined card support surface 12a, thus separating the cards housed in a stacked state from each other. The lowest layer card C inside the card stacker is delivered by a kick roller 15.
