Abstract:
A data communication apparatus has a data communication unit for performing a data communication; a speech unit for performing communication; an output unit for outputting a signal received from a partner station; and a control unit for judging if there is a possibility of communication by the partner and controlling the output unit based on the judgment result.
Abstract:
An image transmitting method in an image transmitting apparatus such as a facsimile apparatus having a plurality of transmission modes in which pixel densities differ. This method comprises the steps of: detecting a size of a recording paper on the reception side; detecting a size of an original to be transmitted; automatically selecting the transmission mode of a high pixel density in the case where the size of the transmitting original is larger than the size of the recording paper; transmitting the image of the transmitting original to the reception side; and detecting the receivable mode on the reception side. With this method, even in case of reproducing the image in the reduction size mode on the reception side, the image with a high image quality can be always derived irrespective of the selection of the image quality mode of the operator.
Abstract:
The communication apparatus is provided with a timer for time counting a predetermined time interval and in the case where a control signal was detected witin a predetermined time interval, the automatic reception is done in the facsimile mode and image information is received. In the case where the control signal could not be detected within the predetermined time interval, the communication is done in telephone mode and the voice-communication is performed. Further, with such a constitution, the facsimile mode and the telephone mode are automatically switched, thereby enabling the image reception or voice-communication to be executed in correspondence upon a communication apparatus on the distant side.
