Abstract
When inserting a MEMORY STICK MS, the tip portion of the MEMORY STICK MS rotates and detrudes the contact pressing plate, so that contact portions of contact terminals 14ai for a SD card SD are pressed down by a rim of slits 20ai of the contact pressing plate 20 up to a position where the contact portions do not interfere with the MEMORY STICK MS.
Claims10
An IC card connector to be used in common for first and second IC cards of different dimensions via a common card inserting opening, comprising:
- a card accommodation portion including a front section for accommodating said first IC card and a rear section formed at a position farther from said card inserting opening than the front section so as to partially overlap with the front section for accommodating said dimensionally different second IC card;
- a group of front contact terminals and a group of a rear contact terminals disposed in the front section and the rear section respectively, for electrical connection with said first IC card and said second IC card respectively;
- a locking/unlocking mechanism fixed to the IC card connector, and
- a contact pressing plate which selectively presses the group of contact portions of the front contact terminals to rotate away from the first or second IC card;
- wherein when the first IC card is inserted, the locking/unlocking mechanism retains the contact pressing plate in a first position wherein the contact pressing plate can rotate, but not slide, and
- when the second IC card is inserted, the contact pressing plate can slide between the first position and a second position, and
- when the contact pressing plate is in the second position, the contact pressing plate can rotate.

An IC card connector, comprising:
- a multiple card accommodation including a first section for removably accommodating via a common card inserting opening a first IC card out of a plurality of IC cards of mutually different shapes, a second section for accommodating a second IC card, formed at a position farther from the card inserting opening than the first section in a line therewith and partially overlapping therewith, and a third section for accommodating a third IC card, formed at a position still farther from the card inserting opening than the first and the second sections, in a line therewith and partially overlapping therewith;
- a group of first contact terminals, a group of second contact terminals and a group of third contact terminals sequentially disposed in a loading/unloading direction of the IC card so as to correspond to the first section, the second section and the third section respectively, for electrical connection with the first IC card, the second IC card and the third IC card respectively;
- a contact pressing plate disposed midway between said group of the first contact terminals and the group of second contact terminals, said contact pressing plate being rotatable so as to press the group of contact portions of the second contact terminals down to a predetermined position or to release the group of contact portions from the predetermined position, said contact pressing plate further being slidable between a first position and a second position according to insertion or removal operation of the second IC card or the third IC card;
- and
- a locking/unlocking mechanism fixed to the IC card connector capable of retaining the contact pressing plate at the first position, wherein
- the contact pressing plate can rotate when in the first and second positions.

- a locking/unlocking mechanism that retains said contact pressing plate selectively in a predetermined attitude;
- and
- a contact pressing plate slidably and rotational movably disposed midway between said group of the first contact terminals and the group of second contact terminals, so as to press the group of contact portions of the second contact terminals down to a predetermined position or to release the group of contact portions from the predetermined position according to insertion or removal operation of the second IC card or the third IC card, wherein
- the locking/unlocking mechanism comprises a locking/unlocking member disposed adjacent to the second section of said multiple card accommodation, having an end portion that selectively keeps an engaged state of retaining said contact pressing plate or a disengaged state of releasing said contact pressing plate according to insertion or removal operation of the second IC card and the third IC card, and a biasing member that biases said contact pressing plate in the disengaged state so as to keep the engaged state.
