The card receiving part has a circular arc part 20PAR corresponding to the step part 16R of the memory card 16 on a side surface of one end part facing the spring support shaft 20S, and a part of the other end toward the spring support shaft 20S side on the side surface. It has a protrusion 20PA.

  A narrow side surface portion connected to the step portion 16R of the inserted memory card 16 is also in contact with the side surface continuous between the arc portion 20PAR and the projection portion 20PA.

  As shown in an enlarged view in FIG. 8, the protrusion 20PA protrudes outward by a predetermined height from the other side surface portion connected to the arc portion 20PAR. The dimension in the thickness direction of the ejection member 20 at the protrusion 20PA is set to be smaller than the thickness of the arc 20PAR. As shown in FIG. 10 and FIG. 11, a narrow width portion connected to the stepped portion 16 </ b> R of the inserted memory card 16 is also in contact with the protruding portion 20 </ b> PA. As a result, both side portions of the inserted memory card 16 are guided by cooperation with the side wall 12WR of the base member 12 facing the side surface on which the protruding portion 20PA and the arc portion 20PAR are formed.

  Note that the protrusion 20PA may be formed at a position closer to the arc portion 20PAR. However, when the protrusion 20PA is formed at a position closer to the rear end, the contact period with the side surface of the memory card 16 becomes shorter, so that wear resistance is increased. Has a sexual effect.

  A groove 20g into which a fixed end portion of a leaf spring 26 that selectively engages with the notch portion 16NB of the memory card 16 is inserted is formed on the inner side of the side surface of the eject member 20 where the projection portion 20PA is formed. ing. The leaf spring 26 as an elastic member has a curved portion at the tip that selectively engages with the notch 16NB of the memory card 16. The curved portion is located inward of a plane including the side surface on which the protruding portion 20PA is formed in the eject member 20 described above. Accordingly, as shown in FIG. 5, the top of the curved portion is inward by a distance D from the position of the side surface of the eject member 20 where the protrusion 20PA is formed, so that the step 16R of the inserted memory card 16 is provided. The narrow portion that continues to the line does not interfere. Further, when the curved portion is pressed by the side surface of the memory card 16, the leaf spring 26 can be elastically displaced with its fixed end portion as a fulcrum as shown by a two-dot chain line in FIG.

  As shown in FIG. 1 in an enlarged manner, the eject member control unit 24 includes a substantially heart-shaped cam element (heart cam) 20HC formed on the side wall 12WL side of the ejector member 20, and a plurality of cam members formed around the heart cam 20HC. As shown in FIG. 4, the gate guide groove 20GG having a step portion of one side is connected to the hole of the side wall 12WL, and the other end portion is slid along the lever guide groove 20GG. Cam lever CL and the pressing spring 10E (see FIG. 2) of the cover member 10 described above.

  The presser spring 10E biases the bent end of the cam lever CL so as to be in sliding contact with the guide surface of the lever guide groove 20GG.

  As shown in FIG. 1, the heart cam 20HC formed of resin has a substantially V-shaped cam surface that is selectively engaged with one end portion of the cam lever CL at a portion facing the inclined surface portion 20F of the eject member 20. is doing.

  As shown in FIGS. 6 and 7, the lever guide groove 20GG and the heart cam 20HC are formed at positions slightly lower than the positions where the leaf springs 26 are disposed. Further, a part of the lever guide groove 20GG and the heart cam 20HC is formed at a position almost directly above the raised portion 12B. Thereby, the thickness of the eject member 20 can be reduced.

  The lever guide groove 20GG branches from the middle of the first guide groove 20G1 to the first guide groove 20G1 that linearly extends along one side of the heart cam 20HC along the side wall 12WL and the other side of the heart cam 20HC. The second guide groove 20G2 extending parallel to the first guide groove 20G1, the one end of the first guide groove 20G1 facing the cam surface, and the one end of the second guide groove 20G2. And a third guide groove 20G3 connecting the portions facing the cam surface.

  One end of the first guide groove 20G1 extends to a rear end 20R that extends substantially parallel to the spring support shaft 20S.

  The average depth of the first guide groove 20G1 is set larger than the average depth of the second guide groove 20G2. The depth of the portion of the first guide groove 20G1 that intersects one end of the second guide groove 20G2 is set to be the deepest. Accordingly, a step portion is formed at the intersection of the first guide groove 20G1 and one end of the second guide groove 20G2.

  In addition, the depth of one end of the guide groove 20G3 is between the end of the first guide groove 20G1 on one end side of the third guide groove 20G3 and one end of the first guide groove 20G1. The depth is set to be deeper than the depth of the groove 20G1. Accordingly, a stepped portion is formed at the boundary portion between the end portion on the one end side of the first guide groove 20G1 and the one end portion of the guide groove 20G3 in the third guide groove 20G3.

  Furthermore, between one end of the second guide groove 20G2 and one end of the guide groove 20G2 in the third guide groove 20G3, the depth of one end of the guide groove 20G2 is the same as that of the third guide groove 20G3. It is set to be deeper than the depth. Accordingly, a step portion is formed at the boundary portion between the end portion on the one end side of the second guide groove 20G2 and the one end portion of the guide groove 20G2 in the third guide groove 20G3.

  As a result, one end of the cam lever CL is guided sequentially through the first guide groove 20G1, the third guide groove 20G3, and the second guide groove 20G2 following the operation of the eject member 20. It becomes.

  In such a configuration, when the memory card 16 is mounted, first, when the front end portion 16F of the memory card 16 is inserted into the accommodating portion 14 through the card slot, the stepped portion 16R is ejected as shown in FIG. The member 20 is engaged with a portion connected to the arc portion 20PAR constituting the card receiving portion, and the side surface portion of the memory card 16 is guided to the side wall 12WR.

  Next, when the front end portion 16F of the memory card 16 is further advanced, the step portion 16R of the memory card 16 is engaged with the arc portion 20PAR of the eject member 20 as shown in FIG. At that time, after the curved portion of the leaf spring 26 is pressed by the side surface of the memory card 16, it is engaged with the notch 16NB of the memory card 16.

  Subsequently, after the memory card 16 is further pressed against the urging force of the coil spring 22 together with the eject member 20, when the pressing force is released, as shown in FIG. The first guide groove 20G1 is separated from the cam surface of the third guide groove 20G3. At this time, the state in which the curved portion of the leaf spring 26 is engaged with the notch 16NB of the memory card 16 is maintained.

  Therefore, the eject member control unit 24 puts the ejector member 20 into a holding state. As a result, the memory card 16 is held in the accommodating portion 14, and the contact pads of the memory card 16 and the contact terminals 18ai are brought into contact with and electrically connected. Further, the memory card 16 that has been mounted is prevented from jumping out to the outside due to the engagement state of the curved portion of the leaf spring 26.

  On the other hand, when the memory card 16 is removed from the accommodating portion 14, the loaded memory card 16 is first pushed in a little further. At this time, when the eject member 20 is advanced, one end portion of the cam lever CL is released from the cam surface and is separated and moved to the second guide groove 20G2, so that the raised portion 20B of the eject member 20 is grooved. It is guided by 12 g and retracted by the urging force of the coil spring 22. Therefore, since the eject member control unit 24 releases the ejector member 20, the ejection of the memory card 16 is started.

  At that time, the counterclockwise rotational moment applied to the memory card 16 based on the pressing force of the eject member 20 acts on the memory card 16 by the reaction force of the protrusion 20PA on the eject member 20 acting on the memory card 16. 12 is applied to the memory card 16, the memory card 16 is not inclined in the direction indicated by the arrow E ′ in FIG. 12, and therefore the memory card 16 is smoothly ejected along the direction indicated by the arrow E. Will be.

  Further, the curved portion of the leaf spring 26 is brought into a state of being engaged with the notch portion 16NB of the memory card 16, as shown in FIGS. Thereby, there is no possibility that the memory card 16 is undesirably dropped from the accommodating portion 14.

  Then, when the end portion of the memory card 16 exposed to the outside is further pulled in the card ejection direction, the curved portion of the leaf spring 26 is made to the notch portion 16NB of the memory card 16 as shown in FIGS. Since the disengaged state is established, the memory card 16 is taken out. At that time, as shown in the enlarged view of FIG. 15, the distal end portion of the curved portion of the leaf spring 26 contacts the inner wall surface 12S of the front end portion of the side wall 12WL. Displacement is regulated. Therefore, there is no possibility that the repeated life (durability) of the leaf spring 26 will be remarkably lowered.

  In the example of the IC card connector according to the present invention described above, the eject member 20 includes the leaf spring 26. However, the present invention is not limited to such an example. For example, as shown in FIG. An eject member 40 that does not have a flat leaf spring may be used.

  The eject member 40 is formed of, for example, a resin material, and, as shown in FIG. 16, a card holding portion formed integrally with a spring support shaft 40S that supports the other end of the coil spring 22, and a card holding portion. And a lever guide groove 40GG that is formed integrally adjacent to the ejecting member control unit 24 and a raised portion (not shown) formed in a portion facing the inner surface of the base member 12. It is configured to include. In FIG. 16, the eject member 40 corresponds to the slope portion 20F and the rear end portion 20R, the first guide groove 20G1, the second guide groove 20G2, the third guide groove 20G3, and the like in the eject member 20 described above. The same slope portion 40F, rear end portion 40R, first guide groove 40G1, second guide groove 40G2, third guide groove 40G3, and heart cam 40HC are provided.

  A raised portion that rises by a predetermined height on the bottom surface of the eject member 40 is movably fitted in the guide groove 12g. The guide groove 12g is formed on the above-described base member 12 so as to extend in the direction in which the memory card 16 is attached / detached. As a result, the eject member 40 is supported so as to be slidable along the direction in which the memory card 16 is attached and detached.

  The card holding part has a card receiving part as an engaged part that is formed corresponding to the shape of the narrow part that continues to the step part 16R of the memory card 16. The card receiving portion has an arc portion 40PAR corresponding to the step portion 16R of the memory card 16 on the side surface facing the inclined surface portion 40F at one end facing the spring support shaft 40S, and toward the spring support shaft 40S side on the side surface. A protrusion 40PA is provided at a part of the other end.

  A narrow side surface portion connected to the stepped portion 16R of the inserted memory card 16 is also in contact with the side surface continuous between the arc portion 40PAR and the protruding portion 40PA.

  The protrusion 40PA protrudes outward by a predetermined height from the other side surface portion connected to the arc portion 40PAR. The dimension in the thickness direction of the ejection member 40 at the protrusion 40PA is set to be smaller than the thickness of the arc portion 40PAR. A narrow portion that continues to the stepped portion 16R of the inserted memory card 16 is also in contact with the protruding portion 40PA. As a result, both side portions of the inserted memory card 16 are guided by cooperation with the side wall 12WR of the base member 12 facing the side surface on which the protruding portion 40PA and the arc portion 40PAR are formed.

  Note that the protrusion 40PA may be formed at a position closer to the arc portion 40PAR. However, if the protrusion 40PA is formed at a position closer to the rear end, the contact period with the side surface of the memory card 16 becomes shorter. Has a sexual effect.

  When such an eject member 40 is used, a cover member 50 as shown in FIG. 17 may be used instead of the cover member 10.

  The cover member 50 having a gate-shaped cross-sectional shape is formed of a thin metal material. As shown in FIG. 17, engagement holes 50 a, 50 b, and 50 c to be engaged with the claw portions of the base member 12 are formed on one side surface portion of the cover member 50 so as to correspond to the claw portions. Has been. On the other side surface portion of the cover member 50, an engagement hole (not shown) with which the other claw portion of the base member 12 is engaged is formed.

  Therefore, the cover member 50 is fixed to the base member 12 by engaging the respective engagement holes with the respective claw portions of the base member 12.

  In addition, a pressing spring 50E that movably supports the cam lever in the above-described eject mechanism is provided on one side surface side of the upper surface portion that connects both side surface portions of the cover member 50. The base end portion of the elastic pressing spring 50 </ b> E is formed integrally with the cover member 50. The holding spring 50E is formed, for example, by punching a part of the cover member 50 toward the inside thereof by press working. Accordingly, an opening is formed around the portion of the cover member 50 corresponding to the pressing spring 50E. Further, a brake piece 50D that brakes a steep protrusion when the memory card 16 is ejected is provided on the other side surface side of the cover member 50.

  Therefore, also in such an example, when the memory card 16 is removed from the accommodating portion 14, the loaded memory card 16 is first pushed in slightly. At this time, when the eject member 40 is moved forward, one end portion of the cam lever CL is released from the cam surface, and is separated and moved to the second guide groove 40G2, so that the raised portion of the eject member 40 becomes the groove 12g. And is retracted by the urging force of the coil spring 22. Accordingly, since the eject member control unit 24 releases the ejector member 40, the ejection of the memory card 16 is started.

  At that time, the counterclockwise rotational moment applied to the memory card 16 based on the pressing force of the eject member 40 acts on the memory card 16 by the reaction force of the protrusion 40PA on the eject member 40 acting in the clockwise direction. Is applied to the memory card 16, so that the attitude of the memory card 16 does not have to be tilted in the direction indicated by the arrow E ′ (see FIG. 12), and therefore the memory card 16 is indicated by the arrow E. It will be discharged smoothly along the direction.

  In addition, an undesired sudden jump-out of the memory card 16 from the accommodating portion 14 is avoided by the brake piece 50D.

  Furthermore, in the example of the IC card connector according to the present invention described above, an eject member 60 as shown in FIG. 18 may be used.

  The card receiving portion of the above-described eject member 40 has a protrusion 40PA and a circular arc portion 40PAR. Instead, the eject receiving member 60 shown in FIGS.

The eject member 60 has the same rear end portion 60E corresponding to the rear end portion 20R, the first guide groove 20G1, the second guide groove 20G2, the third guide groove 20G3, etc. of the eject member 20 described above. The first guide groove 60G1, the second guide groove 60G2, the third guide groove 60G3, and the heart cam 60HC are provided.

  The eject member 60 is formed of, for example, a resin material, and as shown in FIGS. 18 and 21, a card holding portion formed integrally with a spring support shaft 60S that supports the other end of the coil spring 22 described above, A lever guide groove 60GG that is integrally formed adjacent to the card holding portion and forms part of the above-described eject member control portion 24, and a raised portion 60RE formed on a portion (bottom surface) facing the inner surface of the base member 12. (See FIG. 19).

  A raised portion 60RE raised from the bottom surface of the eject member 60 by a predetermined height is movably fitted in the guide groove 12g. As a result, the eject member 60 is supported so as to be slidable along the direction in which the memory card 16 is attached and detached.

  The card holding part has a card receiving part as an engaged part that is formed corresponding to the shape of the narrow part that continues to the step part 16R of the memory card 16.
