摘要： A facsimile system including a facsimile control system implemented with plural microcomputers one of which acts as a master microcomputer coupled to the other microcomputers in a master/slave relationship. At least one of the slave microcomputers has halt and reset inputs coupled to an input/output port of the master microcomputer while another one of the slave microcomputers is coupled through a sub-system in the facsimile system, such as a drive control circuit, to an input/output port of the master microcomputer.

摘要： A signal receiver quantization circuit for an image data transmission device in which received signals are quantized correctly even if they are subjected to distortion in their time positions so that degradation of the received images is prevented. In accordance with the invention, a signal receiver includes a digital PLL circuit, a PLL control circuit for detecting the transition times of an input received signal with the digital PLL circuit being controlled in accordance with an output of the PLL control circuit, and a circuit for sampling the input signal in response to an output signal of the digital PLL circuit. In a preferred embodiment, the PLL control circuit detects the transition times of the input signal only during predetermined time slots determined in accordance with the relative phase between the input received signal and a sampling clock.
