ABSTRACT:
A moving element having secondary keyboard for a portable electronic device is placed between a first member and a second member of the device for providing different keyboard sets to improve readability of text when in different operating configurations. When the second member slides out laterally relative to the first member, the moving element remains stayed in the first member, not moving with the second member. When the second member slides out vertically relative to the first member, the moving element slides with the second member along the sliding groove on the first member, and the moving element is exposed on top of the second member to present a concise dialing keyboard. The secondary keyboard contacts corresponding buttons of a primary keyboard directly. Thus, there is no need to provide additional circuit module exclusively for the secondary keyboard such that the cost and volume can be reduced.
