TELE-WRITING TERMINAL EQUIPMENT

Title:

TELE-WRITING TERMINAL EQUIPMENT

Document Type and Number:

Japanese Patent JPH01296849

Kind Code:

A

Abstract:

PURPOSE:To improve the operation environment of an interactive type picture communication by using an input output integral type digitizer for the input output device of the line drawing information of a tele-writing terminal. CONSTITUTION:The line drawing information inputted by using a pen for an input output integral type digitizer 1-1 is displayed on the display of the digitizer and outputted to a encoder decoder 1-2. The encoding signal from the encoder decoder 1-2 is sent through a modulator demodulator 1-3 and a communication line interface 1-4 onto the communication line. At the tele-writing terminal at the opponent side, a receiving signal is inputted through the communication line interface 1-4 to the modulator demodulator 1-3, and further, outputted through the encoder decoder 1-2 to the input output integral type digitizer 1-1.
