Apparatus for accepting and retaining an information card
First Claim
1. An information card chamber for accepting, retaining and making electrical contact to an information card, the information card chamber having at least a first and a second platform, the first platform raised from the plane of and substantially parallel to the second platform, the information card chamber comprising:
- means for making electrical contact to the information card when the information card is properly inserted, said means for making electrical contact disposed only on a first side of the first platform;
first means for translating the information card away from said means for making electrical contact while said information card is inserted, said first means disposed only on said first side of the first platform; and
second means for translating the information card towards said means for making electrical contact while said information card is inserted, said second means fixedly disposed only on a first side of the second platform.

Abstract
The present patent application discusses a low profile information card chamber (107) used in a radiotelephone (101). The information card chamber accepts, retains and makes electrical contact to an information card (105). The information card chamber (107) makes electrical contact to the information card when the information card is properly inserted (105). The electrical contacts are located on the lower platform (213) of the information card chamber (107). Upon inserting the information card (105) into the information card chamber (107), the information card (105) is translated away from the electrical contacts (205). Prior to being fully inserted, the information card (105) is translated towards the electrical contacts (205). The two translational devices allow an information card (105) to be inserted into the information card chamber (107) without excessive wiping of the electrical contacts (205) by the information card (105).
