Read control system in facsimile equipment

Abstract

Abstract PURPOSE:To decrease the distortion generated on a recording picture at the reception side by sending a read signal to each drive pulse of a pulse motor to make the read position of a data for one scanning line constant at all times. CONSTITUTION:A counter 8 receives a drive pulse sent from a control section 6 to a pulse motor 7 and sends a read signal consecutive for a 1/4 time of the read signal required to read data for one scanning line's share synchronously with the drive pulse to an image sensor 1. A drive pulse with broad pulse interval is sent from the control section 6 as shown in a figure (a) (6) at the start of the pulse motor 7. The counter 8 sends the read signal in a time reading 1/4 of the data for one scanning line's share as shown in figures (b)(6)1-(6)4 synchronously with the drive pulse (6) to the image sensor 1. The image sensor 1 reads sequentially the data for one scanning line's share by 1/4 each at each drive pulse and sends the compression section 2. When the speed reaches a prescribed speed, the read signal reading one scanning line is sent from the counter 8.
