PURPOSE:To attain simultaneous transmission instantly, by interrupting a picture signal and other data signals with each other in a prescribed period in a system transmitting other signals together with the picture signal. CONSTITUTION:An image of an original is formed into a binary picture signal on an image pickup element, and after the application of a horizontal synchronizing signal 3, a data selector 5 is controlled by a count output signal for the period counting ten-and-several bits' share to select an input B. Thus, in the period, a control signal from a sequence controller 7 is applied to the data selector 5 and inserted to the data signal of a composite picture signal. When the period of the data signal is elapsed succeedingly, the data selector 5 selects an input A to start the transmission of the picture signal from an original reader 1. Thus, only two communication lines are used and the picture signal and the other data signals are transmitted instantly without error at the same time. |
