Abstract
A communication terminal device is miniaturized in a shape handy to carry while maintaining the necessary operability. The terminal device is constituted by a first box for voice communication and a second box linked with the first box via short-distance radio link for data input and data display. The first box is provided with minimum functions necessary for the voice communication so as to be small, whereas the second box can be provided with a keyboard high in operability and a relatively large display means so that display and input for data communication can be made conveniently.
