PROBLEM TO BE SOLVED: To simplify a structure and allow inexpensive manufacture by applying a constitution such that a push rod for moving a PC card in a pulling direction via a link member is retained at a holding position, and an operation device for resetting the PC card at a delivery position under a pressing force is provided with a cam having a movable actuator member, as well as a drive part, a locking part and a resetting part for the actuator member. SOLUTION: A lateral projection part 60 of a header body 14a is guided along the forward end of a push rod 50, and the actuator member is mounted on the support pin of a slider which is positioned above a cam groove 66 of the push rod 50, the follower pin of the actuator member moves from the locking part of the cam groove 66 to a drive part via a resetting part, when a push button 58 is depressed. As a result, the push button 58 externally projects and is positioned at a delivery position. When the push button 58 is depressed next, the protection piece 48 of a link member 40 is made to travel due to the actuator member, and then rotates around a support shaft 47, thereby pushing out an eject board 32 together with a PC card locked with an engagement part 36. In this case, the follower pin cannot move in an opposite direction, due the existence of a slope.
