Abstract: A facsimile system having a terminal and a main body. The terminal reads an image and sends the read image to the main body, and the main body transmits the image data received from the terminal through a communication line. The terminal includes a processing instructing unit for instructing processing of the read image at the main body; a first storage unit for storing an identification code specifically assigned to the terminal; and a sending unit for sending to the main body the image data, the instruction data instructed by the processing instructing unit, and the identification code stored in the first storage unit. The main body includes a receiving unit for receiving the data sent by the sending unit; a detecting unit for detecting the identification code from the data received by the receiving unit; and a processing unit for processing the image data received by the receiving unit based on a result of the detection made by the detecting unit.

Abstract: A date communication apparatus in which a message stored in advance is transmitted to a receiving station so as to notify the receiving station that a call-waiting signal has been received, if a call-waiting signal is received by a transmitting station during communication. The reception of a request for line connection from a third station is detected by the call-waiting-signal detecting unit of a transmitting station on the basis of the call-waiting signal transmitted by an exchange. If the call-waiting signal is detected, a preset message is read from a message storage unit, and is transmitted to the other station. This message is transmitted either upon completion of the transmission of all the predetermined data or upon completion of the transmission of data, for instance, in units of pages.

Abstract: A facsimile apparatus receives data from a transmitting station and is provided with a capability for determining when an interrupt request signal has been received from another station. It is first judged whether an error has occurred in received image information on one line. If an error occurrence is detected, its time period is then measured. If the error period coincides with the output time period for a prescribed interrupt request signal, it is determined that an interrupt request signal has been received. Further, it may additionally be determined whether the coincidence has occurred a plurality of times in succession thereby affirming the reception of an interruption request signal.

Abstract: A facsimile machine for facsimile communication with another facsimile machine comprises a host machine including processor for processing data; at least one handy-scanner provided separately from the host machine, for scanning an original document, the handy-scanner including reader for reading image data from the original document, and first transmitter for transmitting the image data read by the reader; and at least one relay station for relaying data signals between the host machine and the handy-scanner, the relay station including second transmitter for transmitting the data received from the first transmitter of the handy-scanner to the host machine, and a buffer memory for temporarily storing the image data before the second transmitter transmits the image data to the host machine, the host machine processing the image data transmitted by the second transmitter.

Abstract: When an interrupt completion detecting unit detects completion of an interrupt processing, a hooking unit executes hooking automatically. A busy tone detecting unit judges whether or not a station of a suspended telephone communication has been holding the telephone circuit. If not, a call is directed to the suspended station on the basis of stored information on its dialing number. At the same time as the hooking is executed, an on-hook judging unit judges whether or not a handset at the own station is in an on-hook state. If it is on the hook, a predetermined processing for urging an operator to lift the handset is executed. This processing selectively causes ringing of a bell incorporated in a telephone unit or of a buzzer, or indication by a display unit or a lamp. With the above procedure, the telephone communication with the suspended station can automatically be restored in accordance with the situations at the suspended and own stations.

Abstract: In a data communication apparatus, when detecting a "catch phone" signal sent out from an exchange, a receiving station requests a transmitting station to resend data by use of protocol information. At the transmitting station, the data resending request is detected in a protocol information analyzing unit, and a predetermined unit of data which was transmitted immediately before the present time is resent. The receiving station has a page deleting unit to save the memory area used to store the data resent and avoid printing of unnecessary data. The page deleting unit enables deletion of data received when a "catch phone" call comes in and permits the resent data to be effectively stored in a memory. Also, in the apparatus, a "catch phone" detecting unit in a transmitting station detects that a circuit connection request comes in from a third station on the basis of a "catch phone" signal sent out from an exchange. A page-end detecting unit detects completion of transmission of a predetermined unit of data.

Abstract: A facsimile network system capable of carrying out broadcast communication which enables documents in a memory of a key station to be sent automatically to multiple remote receiving stations at regular intervals. A sending sheet which is attached to the documents as a first page including names (addresses) of the key station (sender) and the remote receiving stations, date and message, is automatically prepared in the facsimile machine, so that it is transmitted together with the documents.

Abstract: A data communication apparatus in which if it is determined that a distant station presently in communication is a called station by a distant-station discriminating means, and a call-waiting signal is detected by a call-waiting-signal detecting means, a call-waiting-telephone controlling means is activated. This call-waiting-telephone controlling means switches over the line to the interrupting-station side by controlling a line switching means, and commences processing for an interrupt communication by a call-waiting telephone. Thereby, even if there has been an interrupt request signal, an interrupt communication is not allowed if a distant station presently in communication is in a chargeable state.
