A card connector has a connector main body including therein a first cam block extending along the card-receiving inserting slit and capable of a first horizontal movement and also a second cam block extending along the inserting slit and in parallel relation with the first cam block. The second and first cam blocks cause the second cam block to move in a second horizontal direction by one directional first horizontal movement of the first cam block, and are brought to be in cam engagement by a first cam surface for causing the second cam block to move in the second horizontal direction by a first half movement of the first horizontal movement in the other direction. The second and first cam blocks are brought to be in cam engagement by a second cam surface for causing the second cam block to move in the vertical direction by a latter half movement of the horizontal movement in the other direction. In addition, the second cam block urgingly presses the contact to bring it to be in an opening state by the second horizontal movement and removes the pressure the contact so as to bring it to be in a closed state. Furthermore, the vertical movement causes the card to be pushed up to slide and rub the contacting surface for ensuring a good contact.
