A connector device in which a push rod can be locked in a predetermined approach position when an IC card is connected. The structure of an ejection mechanism is simplified, and the number of parts is reduced and assembling operability is improved. The push rod is held so as to reciprocate movably while constantly biased in an IC-card ejection direction, outside of a frame to guide insertion/removal of the IC card. A transmission pin attached to the push rod is engaged with a heart-shaped cam groove provided in an outer side surface of the frame. The transmission pin is constantly biased by a spring force of an elastic piece integrated with the push rod toward the cam groove. When the IC card is inserted, as an operation member of the transmission pin is held in the cam groove, the push rod is locked in the predetermined approach position. When the push rod, lock-released and projected, is pushed to the approach position, the transmission pin drives a driving plate entering the cam groove, to eject the IC card via an eject arm.

[ What is claimed is:] [1.] A connector device having a frame attachably/removably supporting an IC card, a push rod held by the frame so as to reciprocate movably and elastically-biased in an IC-card ejection direction, and a number of pin contacts connected to socket contacts of the IC card in inserted status, wherein the IC card in inserted status is ejected by pushing said push rod, said device further comprising:a heart-shaped cam groove fixed to said frame;a transmission pin attached to said push rod such that said push rod can move along the heart-shaped cam groove;a driving body movably held and adapted to be in contact with said transmission pin in a predetermined position;an eject arm interlocked with said driving body; andan elastic piece, integrally provided with said push rod, that elastically-biases said transmission pin toward said heart-shaped cam groove,wherein said transmission pin is locked at two positions of said heart-shaped cam groove, whereby said push rod is locked in a predetermined approach position and a projected position projected from the approach position by a predetermined amount,and wherein when the IC card is inserted, by a first push operation with respect to said push rod in said approach position, said transmission pin is guided along said heart-shaped cam groove, thus said push rod withdraws to said projected position, and by a second push operation with respect to said push rod in said projected position, said transmission pin drives said driving body to eject the IC card via said eject arm.
