In the present invention, after an image mail is transmitted to a receiving-end machine (S, S), when a reception error occurs, an image format of image data in the image mail is altered, and the image mail including this image data (retransmission image mail) is retransmitted to the receiving-end machine (Sthrough S). That is, it is attempted to avoid the occurrence of the communication error due to the image format, by altering the image format of the image data and retransmitting the same. With this arrangement, it is possible to avoid successive occurrence of the communication errors, even if the transmission data is retransmitted. Thus, as compared to the arrangements in which retransmission is not carried out at all or identical transmission data is retransmitted, the present arrangement can improve the efficiency of data transmission.

Data transmission device, data transmission method, data transmission program, data reception device, data reception method, data reception program, and communication system

In a communications device, a terminal machine transmits/receives data over a network and makes a request for a response to a data transmission from a receiving-end machine. In the terminal machine, an e-mail message identifying unit determines whether data to be received over the network is response data to the response request, and a main control unit controls so as to preferentially receive data identified as the response data by the e-mail message identifying unit over other data. Thus, if an e-mail message is transmitted with a request for a disposition verification, a reply message to the disposition verification request can be quickly received from the receiving-end machine.

Communications device and communications method

A communication system serving as a transmitter terminal and a receiver terminal for communications with a second communication system via a communication line, the communication system includes a storage section for data storage; a communication section for data communications, the communication section being adapted for reception and transmission of data and size information indicative of the size of the data with respect to the second communication system; a detection section for detecting a free space in the storage section; a comparing section for comparing the data size contained in the size information with the size of the free space in the storage section; a calculating section for, if the storage section is short of free space for accommodation of the data size, calculating a waiting period required for recovery from the shortage of the free space in the storage section; and a timer section for timing the lapse of the waiting period.

Communication system and method, and storage medium for the system

An image processing apparatus includes a joining-portion processing section for combining partial images that have been read in a divided manner. Focused on partial document data predeterminately specified among a plurality of partial document data stored in an image memory, the joint-portion processing section performs a recognizing operation on the joints, a positioning operation and other operations beginning with the proximity of the specified partial document data. The partial images are then combined together to form one complete image. For example, in the case of copying an original document, which is of a size too large to be copied in one operation, on one sheet of paper in a reduced manner, it becomes possible to eliminate time consuming tasks such as trimming and pasting of the partial documents as well as calculating of the reduction rate. Thus, the efficiency of the operation is improved, and by specifying the partial document data from which the operation is started, it is possible to join the partial images accurately irrespective of the order of inputting the partial documents.
