A slide/tilt mechanism is provided to include a base plate; a slide plate which is slid between a closed position and an open position with respect to the base plate; a guide plate which supports the slide plate to make the slide plate movable; a tilt mechanism which tilts the slide plate with respect to the base plate by inclining the guide plate with respect to the base plate; an elastic member which actuates the slide plate in a slide direction and a tilt direction; and a tilt restriction member which engages the tilt mechanism to restrict the inclination of the guide plate when the slide plate is slid from the closed position to the open position, and disengages the tilt mechanism to permit the inclination of the guide plate when the slide plate reaches the open position.
