And the other end of the lever 4 is inserted into the insertion guide 2.
The lever 4 is rotated counterclockwise in FIG. 1 around the fulcrum 13 on the upper surface of the end wall 10 of the connector body 1 by the pressing operation of the rod 5 by engaging with the tip of the operating rod 5 extending from the side. Then, the eject plate 3 is slid to the near side by this rotation, and the IC card A is pushed out to the near side via the claw piece 3a. 3 and 5, the end wall portion 10 of the connector main body 1 is formed to be slightly lower than the upper surface of the connector main body 1 with which the eject plate 3 slides.
The lever 4 can be interposed between the lower surface of the eject plate 3 and the upper surface of the end wall portion 10. Further, the central portion of the upper surface of the end wall portion 10 and the portion on the near side thereof are provided with respect to the cut portion 3b. The escape groove 14 is formed so that the entire ejection mechanism including the lever 4 is within a dimension obtained by adding the thickness of the ejection plate 3 to the thickness of the connector body 1. Protrusions 15 projecting forward are formed on both sides of the connector main body 1, and mounting brackets 16 for fixing the connector main body 1 to a circuit board in a body of an electronic information device or the like are fixed to each of the protrusions 15. At the same time, a projection 17 for positioning with respect to the circuit board is protruded from the lower surface of the connector main body 1, and a pair of rails 18 extending on both sides of the connector main body 1 are extended. A guide groove 18a that fits into the side edge portion A2 of the IC card A was formed in the first embodiment.

As shown in FIGS. 1, 4 and 5, the insertion guide 2 includes a pair of rail members 20 and 21 made of synthetic resin,
And a connecting plate 22 made of a thin metal plate that holds the rail members 20 and 21 across the rail members. The rail members 20 and 21 are provided with side edges A on both sides of the IC card A.
2, the guide grooves 20a and 21a are formed, and the engaging pieces 20b and 21b extending forward are integrally extended, and the engaging pieces 20b and 21b are formed on the connector body 1 in the respective rail portions 18 respectively. The insertion guide 2 can be connected to the connector main body 1 by engaging with the engagement groove 18b on the outer surface of the rail, and in this connection state, the guide grooves 20a, 21a of the rail members 20, 21 and the guides of the rail portions 18 are formed. The groove 18a was aligned on a straight line.

Each connecting member 22 has a rail member 20, 21.
The claw piece 22a inserted and locked in the vertical through-holes 20c, 21c formed at the bottom is cut and raised downward, and furthermore, both sides of the connecting plate 22 are arranged along the outer surfaces of the rail members 20, 21.
