Abstract: A cordless facsimile system capable of realizing a telephone answering function, without a separate telephone answering device. The cordless facsimile system with a telephone answering function includes a stationary base unit connected to a public switched telephone network (PSTN) and a cordless, mobile facsimile unit in radio communication with the base unit.

Abstract: A call screening method for a facsimile system having a stationary main unit connected to a telephone network and at least one cordless portable unit for enabling a user to screen an incoming call during an automatic telephone answering function. A telephone answering device incorporated into the stationary main unit is used to record an incoming message of an incoming call received from the telephone network while performing an automatic telephone answering function. A RF transceiver is used to form a radio communication link with the cordless portable unit of the facsimile system in order to output the incoming message as received at the stationary main unit to a speaker, of the cordless portable unit while the incoming message is being recorded in the telephone answering device at the stationary main unit to permit the user to screen an incoming call.

Abstract: A facsimile apparatus has a plurality of portable units, and enables a subscriber to make a call reservation and conduct a telephone conversation on the reserved call, using the portable units. A base unit of the facsimile apparatus sets up a call reservation in response to a call reservation request signal from the portable unit, while the facsimile apparatus transmits and receives image data. Upon completion of transmitting and receiving the image data, the base unit connects a voice communication path between the portable unit and a facsimile of the other party, so that the subscriber can make the call reservation and talk with the other party over the telephone by using the portable unit.

Abstract: A method of recording a telephone conversation in a cordless facsimile system including a cordless facsimile apparatus, a portable unit, and a base unit connected to a public switched telephone network, for wirelessly connecting the cordless facsimile apparatus to the portable unit. The portable unit wirelessly transfers a telephone conversation recording command to the wireless facsimile apparatus according to the telephone conversation recording command input by a user of the portable unit. Upon receiving the telephone conversation recording command, the cordless facsimile apparatus receives an RF signal corresponding to the telephone conversation, being transferred between the portable unit and the base unit, converts the received RF signal to voice data, and stores the voice data in a memory. Also, the portable unit can transfer a telephone conversation playback command to the cordless facsimile apparatus according to the telephone conversation playback command input by the user of the portable unit.

Abstract: A facsimile apparatus having a mobile unit prints set contents of the mobile unit on the recording paper, so as to allow the user to confirm the set contents accurately. The mobile unit reads set contents data stored in a memory of the mobile unit in response to a print request for the set contents and transmits the read set contents data to the facsimile apparatus. Then, the facsimile apparatus receives the set contents data and prints the set contents on the recording paper. The print request is made by depressing a print request key of the facsimile apparatus or of the mobile unit.

Abstract: A technique for informing a calling party of a no-paper state while a facsimile machine receives image data. If no paper is sensed while the facsimile machine receives image data, a call reservation is made. If the calling party responds to the call reservation, a voice message indicating that there is no paper is sent to the calling party.

Abstract: An equalizing circuit and method for data communication terminal equipment includes: a level detecting unit for detecting respective levels of a high frequency signal and a low frequency signal which are frequency shift keying signals inputted through a telephone line during a handshake and for outputting the detected respective levels; a control unit for comparing the levels of the high and low frequency signals detected by the level detecting unit and for generating a frequency compensation amplification control signal according to a level difference between the high and low frequency signals; and an equalizing unit for inputting a level detection signal outputted from the level detecting unit and for compensating any attenuation and distortion of received signals in response to the frequency compensation amplification control signal of the control unit, so as to effect equalization.

Abstract: A device for automatically transmitting a document in a facsimile system includes a central processing unit (CPU) that enables automatic transmission of image data from a document by dialing a telephone number recorded on the document in response to entry of a transmission start key. A key input unit includes the transmission start key and a number of function keys and provides key data to the central processing unit (CPU). A scanner scans the image data and the telephone number recorded on the document and converts the scanned image into digital image data. A pattern recognition unit recognizes the pattern of the telephone number scanned by the scanner. A dialing unit transmits a dialing signal through a public telephone network, and a line interface unit (LIU) forms a data transmission path with a receiving facsimile device to enable transmission of the image data.
