An input receiving apparatus receives an input such as an order slip transmitted from a facsimile apparatus at a user terminal. The user makes a conversation reservation before the user transmits the image data of the order slip. After the input receiving apparatus receives the image data, the input receiving apparatus switches a connection line from a facsimile receiving apparatus to a facsimile transmitting apparatus within the input receiving apparatus within the same call upon receipt of the conversation reservation signal automatically transmits a switching signal to the facsimile apparatus at the user end and performs a character recognition by extracting a character portion from the image data, thereby preparing a return image data based on the character recognition. When the facsimile apparatus at the user end is ready for receiving the return image data, the input receiving apparatus transmits the return image data. The user confirms his order by observing the return image and then issues a PB signal.
