Claims (1)

[Claims for Utility Model Registration] 1. Image data to be transmitted is stored in an image memory, the stored image data is read out and modulated, and transmitted through a transmission line, and the read image data is converted into analog data using a digital/analog converter. A transmitting device converts the image data into a signal and displays it on a television rate transmission monitor, demodulates the image data transmitted through the transmission line and stores it in an image memory, reads out the stored image data, and converts it to a digital/analog converter. It is equipped with a receiving device that converts the signal into an analog signal and displays it on the TV rate receiving monitor, and by pointing a desired position on the screen of the transmitting monitor or the receiving monitor with a light pen, the corresponding signal can be displayed on the monitor of the other party or both parties. What is claimed is: 1. A still image transmission device that displays a marker at a designated position, wherein a signal corresponding to the indicated position is directly applied to the digital/analog converter on the signal receiving side or both sides. 2. The still image transmission device according to claim 1, wherein an address memory is provided in the transmitting device and the receiving device,
After a signal corresponding to the indicated position is stored in the address memory, it is applied to the digital/analog converter, and the contents stored in the address memory are transferred after a certain period of time or to the signal corresponding to the new indicated position. A still image transmission device characterized by erasing data during transmission. 3. The image transmission device according to claim 1, wherein both the transmitting device and the receiving device include first and second image memories as the image memories,
The first image memory stores image data to be transmitted or received, and the second image memory stores image data transferred from the first image memory and a signal corresponding to the designated position. west,
A still image transmission device characterized in that the contents of a first image memory are transferred to a second image memory after a certain period of time or when a signal corresponding to a new designated position is transmitted.
