The cam responsible for ejecting the tape is stuck. Unplug the unit, unscrew the back from the front, and loosen the tape from the drum on the right side.
On the left side, find the tiny motor on a pulley that turns the giant white gear-cam. There should be a small wheel on the pulley; rotate it gently with your finger until the tape ejects.
