Does it fit to Ipad Mini aswell?

You can't use the kit to copy any content of the iPad, you will need to copy them from the iPad to your computer e.g. using the windows camera wizard on a PC; Image Capture, iPhoto or Aperture on a Mac : http://support.apple.com/kb/HT4083

The iPad has the lightning connector, so that uses the lightning to SD card reader and the lightning to USB camera connector, but the page that you posted from still applies.

If you copy the photos onto an SD card yourself, as opposed to using it with a camera, then for the photos to be recognised by the iPad you will need to create a DCIM directory off the root of the card, with the photos underneath it, and the photo filenames need to be exactly 8 characters long (no spaces) plus the file extension i.e. in a similar format as if a camera had created/written them

The two things that I linked to (the lightning SD card and USB camera connector) will work with the iPad Mini.

You can only used them to copy photos and videos from an SD card or your camera to the iPad's Photos app, they can't be used to copy them off the iPad to a USB stick or anything else.

To copy them off the iPad you will need to connect the iPad to a computer
