The facsimile apparatus of this invention performs recognition processing by storing image data received from a transmitting terminal and by decoding the image data stored. The image data received is relayed and transmitted to multiple destinations on the basis of the result of this recognition.

Facsimile apparatus

A communication apparatus capable of transmission and reception simultaneously through a plurality of communication channels of an ISDN basic interface has a communication mode which leaves at least one of the plurality of communication channels free. If this mode has been set, transmission or reception is allowed when this one communication channel among the plurality thereof is made free for the transmission or reception.

Communication method and apparatus

A communication apparatus connectable to an ISDN network and having a communication function and a data communication function comprises a memory for storing a destination number in a speech mode, an instruction unit for instructing data communication in the speech mode, and call means for calling based on the destination number stored in the memory in response to an instruction from the instruction unit.

Apparatus for speed and data communication

When data communication is to be performed, character code data and image data are divided into different block areas, the block area of the image data is further divided into block areas in accordance with image characteristics of the image data, and the data of the respective block areas are communicated, thereby efficiently communicating the data.

Data communication apparatus for converting data in accordance with a

A process for transmitting mixed data, composed of character code data and bit image data in blocks and an apparatus therefor. Efficient transmission can be achieved by selecting the size of blocks suitably according to the quantity of data in each block or the number of blocks.

Data communication process and apparatus for data transmission in blocks

A facsimile apparatus in which the pixel density of image data being received or transmitted can be converted when the image being received or to be transmitted is formed. The apparatus photoelectrically reads a document image at a fixed pixel density and can be manually instructed to execute or not to execute a conversion process on the pixel density of the read image data. If instructed to execute the conversion process the image data whose pixel density has been converted is encoded and transmitted, and if instructed not to execute the conversion process the non-converted image data is transmitted.

Facsimile apparatus with controllable pixel density for image formation

Data communication apparatus

A communication terminal device has a memory for storing data to be transmitted, means for sending out the data stored in the memory to a line for transmission to a receiving station, and a control for converting a portion of the data from the memory so that the converted data are compatible with the type of the receiving terminal.
