Emachine t6412

I have the above emachine computer. I took the sm card out of my camera and was going to print some pics.
I was too far to the right and instead I held the card to /miccrodrive slot and my card fell inside the computer. I need to know how to get it out. I took the side off and could not see it. I am going to go back and take the other side off, but I don't think it is in that part of the computer. Can you help me? There are so many precious pictures of my family on this. I appeciate any help you can give me. Thank you!
