2. Description of the Related Art
Regular card readers are commonly designed to read different memory cards such as SM card, memory stick, SD card, and multimedia memory card. However, conventional multipurpose memory card readers cannot read a xD memory card, which is a storage medium developed by Japan Olympus and Fuji. The capacity of a xD memory card can easily be expanded to over 8 GB. This high capacity memory card is practical for use in image processing. It is regrettable that conventional card readers cannot read a xD memory card.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a memory card connector, which fits any of a variety of memory cards including SM card, memory stick, SD card, multimedia memory card, and xD memory card. It is another object of the present invention to provide a memory card connector, which has a thin thickness.
To achieve these and other objects of the present invention, the memory card connector comprises a housing, the housing comprising a front side, a rear side, an open chamber extending to the front side for the insertion of a memory card into the inside of the housing, two stepped portions bilaterally disposed at a front side of the open chamber, a plurality of elongated slots and a recessed chamber arranged in a top wall thereof, and two locating notches symmetrically disposed at two sides thereof; a plurality of first terminals mounted in the housing for the contact of a memory card, the first terminals each having a first end inserted from the rear side of the housing into the inside of the open chamber and the elongated slots, and a second end curved downwards and then upwards outside the housing; a plurality of second terminals mounted inside the housing for the contact of a memory card, the second terminals each having a first end respectively inserted from the rear side of the housing into the inside of the open chamber and suspended below the first terminals, and a second end curved upwards and then downwards outside the housing; a plurality of third terminals mounted inside the housing for the contact of a memory card, the third terminals each having a first end inserted from the rear side of the housing into the inside of the open chamber and suspended below the second terminals, and a second end curved upwards and then downwards and respectively suspended between the second ends of each two adjacent second terminals, the third terminals include longer third terminals and shorter third terminals; a plurality of fourth terminals mounted inside the housing for the contact of a memory card, the fourth terminals each having a first end turned inwards at right angles and then backwards, and a second end turned upwards and then downwards outside the housing, the fourth terminals including a number of spaciously pitched fourth terminals to be alternatively arranged with the longer third terminals at same elevation; a lever fastened pivotally with a part inside the housing and transversely suspended in the front side of the open chamber for controlling the insertion of an assigned memory card into the open chamber.
