DATA COMMUNICATION CONTROL DEVICE, IMAGE READING DEVICE, AND IMAGE FORMING APPARATUS

摘要

A data communication control device includes a transmitting unit that transmits data; and a receiving unit that receives the data through a communication line. The transmitting unit includes a transmitting component that transmits an establishment signal of establishing communication to transmit the data to the receiving unit, and a first controller that controls the transmitting component. The receiving unit includes a receiving component that receives the data transmitted by the transmitting component, and outputs a confirmation signal of confirming the establishment of the data communication with the transmitting component when receiving the establishment signal, and a second controller that controls the receiving component, and transmits a notification signal of notifying the first controller about the establishment of the data communication through a dedicated line different from the communication line when receiving the confirmation signal. The transmitting component starts transmitting the data when the first controller receives the notification signal.
