Abstract: A communication system is constructed by interconnecting a data terminal and a communication terminal via an interface. The communication terminal receives text data created by the data terminal, develops these data into image data and then transmits the image data. In response to a command from the data terminal, the communication terminal uses a reader to read the image of an original, thereby acquiring image data, and transmits these image data to a line. On the other hand, the order of transmission of the image data based upon the text data and the image data based upon the reading of the image of the original is set at the data terminal. On the basis of the order of transmission set, the data terminal controls the execution of transmission of the two types of data in the communication terminal.

Abstract: In a portable facsimile apparatus according to this invention, each recording paper (or each document to be transmitted) may be set in place by manual operation. In a case where the portable facsimile apparatus needs additional recording paper (or an additional document) to be set by an operator during image reception or image transmission, the portable facsimile apparatus so informs the operator, while the apparatus delays shifting following image reception or image transmission. As a result, the operator can set additional recording paper (or an additional document) into the portable facsimile apparatus, during image reception, without terminating the image reception.

Abstract: A communication apparatus is provided which is capable of facsimile communication, voice communication and concurrent voice/facsimile communication. In one version, the apparatus has first and second connecting units for connection to a voice communication terminal (such as a conventional telephone) and a data communication terminal (a facsimile apparatus or the like), respectively. A selector selects between those two connecting units. An analog signal from either the voice communication terminal or the data communication terminal is binarized, the two streams of data (if the apparatus is in concurrent transmission mode) are mixed, and the resulting data stream is converted to an analog signal for transmission. Similarly, an incoming analog signal, if received in the concurrent communication mode, is separated into binary voice and binary non-voice data, which are then separately processed and output as appropriate. Also, it is possible to switch among voice, data, and concurrent voice/data modes.
