  • the first engaging member 61 is rotatably coupled to the ejecting member 23 . In the state where the first contacting portion 61 c is applied with the load of the elastic member 29 via the second engaging member 71 , the first engaging member 61 is rotated around the rotation shaft 63 . Thus, the locking portion 61 a is kept pressed against the card 51 .

  • engagement between the locking portion 61 a and the locked portion 51 a in the predetermined direction is released so that the card 51 can be removed from the connector.
  • the ejecting mechanism 21 moves the ejecting member 23 in the ejecting direction B together with the card 51 .
  • the ejecting member 23 reaches the ejecting position together with the card 51 , compression of the elastic member 29 is released and the urging force is small so that the braking force of the braking device is small. Therefore, the first engaging member 61 can be relatively easily rotated clockwise. As a consequence, the card 51 can easily be removed from the connector.
  • the locking portion 61 a and the first contacting portion 61 c have phases selected so that, when the card 51 moves from the connecting position to the ejecting position, the locking portion 61 a is pressed by an edge of the locked portion 51 a of the card 51 to rotate the first engaging member 61 clockwise as shown in (b) of FIG. 11 and, therefore, the first contacting portion 61 c presses the second engaging member 71 to move upwardly as shown in (b) of FIG. 11 .
  • the first engaging member 61 is rotated to an angular position shown in (b) in FIG. 11 by a slant surface 51 b of the card 51 .
  • the card 51 is inserted.
