The cellular phones, PDAs, GPSs, and electronic reading devices become necessary equipment for almost every person and the aesthetic outer appearance attracts the user's attentions directly by its color, texture and patterns. The outer appearance shows the personality of the user. However, the users cannot change the outer appearance of the electronic devices easily because the shape, the colors and the patterns are integral to the casing. Therefore, replaceable cases are developed to allow the users to change the casings as desired.
