備する。Moreover, the portable part 3 is a foldable laptop type,
A transmitting/receiving unit 301 that transmits and receives radio waves to and from the transmitting/receiving unit 204, and a memory 3 that temporarily stores image data to be transmitted and received.
02. Separation and combination unit 303 that separates and combines audio signals and image data, camera 304, speaker 305, liquid crystal display 306, microphone 307, echo canceller 30
8. A control section 309 consisting of a microcomputer that controls the entire system, an operation section 319 for performing operations such as off-hook, dialing, and image transmission switching, and a battery 311 are provided.
この実施例では、操作部２０６の操作によってネットワ
