止画像伝送装置。 In a still image transmission device that transmits television images using a narrowband transmission path such as a telephone line, a counter that counts at least a signal indicating completion of writing to a memory multiple times, and a binary counter that sequentially counts the counting results. , a decoder that decodes the output of the binary counter, and a driver circuit that drives a switching circuit such as a relay using the output of the decoder,
The video signal selected by the driver circuit is
By storing the signal in memory after D conversion and sending it out to a narrowband transmission line, multiple input video signals are automatically selected for each arbitrary number of images to be transmitted, converted into still images, and transmitted to a remote location. A still image transmission device characterized by:
