Abstract:
1. An image data transmitting apparatus comprising: document reading means for reading a document set therein; image data storing means for storing the image data of the document resulting from reading; communication means connected to an image data receiving apparatus via a communication line; and trouble detecting means for detecting a transmission trouble which has occurred in transmitting the image data by the communication means, wherein when the trouble detecting means detects the transmission trouble, a reading operation of the document reading means and a transmission operation of the communication means are stopped, and when the documents are set in the document reading means thereafter again, the reading operation of the document reading means and the transmission operation of the communication means are restarted, the image data transmitting apparatus further comprising: transmitted-sheets-number storing means for storing a number of document sheets for which image data is completely transmitted by the communication means by a time when the interruption of transmission is carried out by reason of occurrence of the transmission trouble, wherein in retransmitting image data for all the documents, discrimination data is added to the image data for the documents to discriminate between image data which is already transmitted and image data which is not transmitted yet, based on the data stored in the transmitted-sheets-number storing means.
