Demand for an inexpensive color facsimile apparatus is expected not in the business field but in home use, and a product which is easy to operate and use is required in consideration of home use. Such color facsimile apparatus, i.e., an image communication apparatus has a communication means for communicating with a partner terminal via a line, a DRAM ( ) for storing image information received by the communication means, a management means for managing the image information stored in the DRAM ( ), decoding means for decoding the image information stored in the DRAM ( ) into image data to be recorded on a recording paper sheet, and a recording unit ( ) for recording a visible image on a recording paper sheet on the basis of the decoded image data using a selected attached ink cartridge. A CPU ( ) of the image communication apparatus counts C indicating the number of non-recorded color images stored in the DRAM ( ), M indicating the number of non-recorded monochrome images, C indicating the number of recorded color images, and M indicating the number of recorded monochrome images. When a value C &plus;M is not zero, the CPU displays a message indicating that a new image is stored in the DRAM ( ) using a first display unit on a control panel ( ). When the value C is not zero, the CPU displays a message indicating that a new image is stored in the DRAM ( ) using a second display unit independent from the first display unit.

Image communication apparatus and its control method

Whether a call is placed after waiting for confirmation operation or without waiting for confirmation operation upon completion of speech recognition is selected. Data is initialized in the standby state, and upon instruction of speech recognition, speech recognition is done. The speech recognition result is displayed, and when a speech recognition key is operated without any confirmation operation, speech recognition is redone without setting the standby state.

Apparatus for making outgoing call

An image communication apparatus and a communication controlling method thereon, wherein in the case where image data having an attribute not specified by the ITU-T recommendation is transmitted, regardless of an attribute of image data to be transmitted, a reception command including a first image attribute specified by the ITU-T recommendation are sent out, and information including a second image attribute of image data to be transmitted is sent out in a phase transmitting the image data after the reception command is sent out. And when an image is transmitted with the second image attribute, a transmission takes place with a binary file transfer communication procedure following a first communication procedure specified by the ITU-T recommendation so that image data having an image attribute not standardized by the ITU-T recommendation can be transmitted.

Image communication apparatus and communication control method thereof

A communication apparatus for performing auto-redial processing for repetitively calling a distant station using a prestored call number until a connection can be attained, includes a response state detection unit for detecting a response state of the distant station or an exchanger through a line after a calling operation is started, and a control unit for judging according to a detection state of the response state detection unit whether or not the call number is correct, and for, when it is judged that the call number is false, interrupting the auto-redial processing.

Communication apparatus

A data communication apparatus for performing a communication of a procedure signal at a low transmission speed, and performing a communication of data at a high transmission speed, includes a discrimination unit for discrimination whether or not a received signal is an echo signal, and a detection unit for detecting reception of one of high- and low-speed signals according to a discrimination result of the discrimination unit at a timing at which the high- and low-speed signals in communication may be received.

Data communication apparatus

A facsimile apparatus which transmits original image data separately in accordance with size of receiving sheets at a receiving station includes a receiving page counter for counting the number of the receiving sheets on which the original image data is reproduced, and data corresponding to count value of the page counter is transmitted to the receiving station.

Facsimile apparatus and facsimile communication method

A data communication apparatus having an error retransmission mode allows the operator to ascertain an amount of error data when an error is contained in data and when the error is not corrected despite retransmission of the error a predetermined number of times, or makes it possible to reproduce data with respect to correctly received data by discriminating correct data contained in error data, thereby preventing error data from becoming wasted as practically as possible. In addition, at the time of error retransmission, a transmission mode for retransmitting the error data is changed so as to minimize the number of incidents of error retransmission, thereby to enable efficient data transmission.
