Description

  The present invention relates to a card connector including a card tray for receiving a card and a connector main body into which the card tray is inserted and removed.

  It may be necessary to place the card on the lower surface of the card tray in the posture of being inserted into the connector body. For example, the card is placed on the lower surface when the card is placed on both the upper and lower surfaces of the card tray or when the connector body is mounted on the downward surface of the circuit board.

  When a card is placed on the lower surface of the card tray, a structure for preventing the card from dropping is required. As one of the structures for realizing this, it is conceivable that the card is inserted into the card tray from the lateral direction, and a groove into which the edge of the card enters when the card is inserted is provided in the card tray. If this structure is adopted, even if the posture of the card tray is changed to a posture in which the surface on which the card is placed faces downward, the card can be prevented from falling.

However, if you adopt a structure that slides the card horizontally and puts it on the card tray,
It is conceivable to try to insert the card tray into the connector body while the card is halfway inserted into the card tray. If an attempt is made to insert the card tray into the connector body while the card is inserted halfway, the card may abut against the connector body and cannot be inserted. Alternatively, not only can the insertion become impossible, but the card or the card connector may be damaged.

  Here, Patent Document 1 discloses a memory device that is not a card tray, but is a type in which a plurality of cards are inserted sideways into a holder and the holder is inserted into an apparatus main body. In the case of the memory device of Patent Document 1, the card needs to be completely inserted into the holder. If the holder is to be inserted into the device main body with the card protruding laterally from the holder, the card will hit the side of the insertion port of the device main body.
