Claims

[Scope of utility model registration request]

It consists of a central control unit that sends out image data, and a terminal device that writes the received image data into a refresh memory and displays an image on a cathode ray tube based on the image data read out from the refresh memory. In an image display device which is configured to send out a reception confirmation signal when the reception confirmation signal is received and to send out the next image data when the reception confirmation signal is received by the central control unit, the end unit is operated by a switch operation. An image display device comprising a reception confirmation delay circuit that appropriately delays the sending timing of a reception confirmation signal.
