Abstract
Abstract A facsimile apparatus comprises a communication control unit for establishing a connection, the communication control unit sending station identification data to a calling station and receiving station identification data from a called station for identification of the station, an image data transmission and reception unit, an image reading unit, an image recording unit, a memory for storing the station identification data of selected stations; and a memory control unit for controlling the memory such that, when a call is made to a called station, the station identification data that is returned from the called station is stored in the memory as the station identification data of the selected stations. The communication control unit rejects reception of the image data transmitted from the calling station when the calling station is not included in a list of stations stored in the memory.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
307 words
A facsimile apparatus for transmitting and/or receiving image data to and from another facsimile apparatus in another station, comprising: communication control means connected with a communication line for establishing a connection with another station via the communication line, said communication control means sending station identification data to a calling station for identifying own station when a call is received from the calling station, said communication control means further receiving station identification data from a called station, when the facsimile apparatus has made a call to the called station, for identifying the called station; image data transmission and reception means for transmitting image data to the called station via the communication control means when a call is made to the called station and for receiving image data from the calling station via the communication control means when a call is received from the called station; image reading means for reading an image and producing the image data corresponding to the image, said image reading means transferring the image data to the image data transmission and reception means for transmission to the called station; image recording means supplied with the image data received from the calling station from the image data transmission and reception means for recording the image data on a recording sheet as a reproduced image; memory means for storing the station identification data of selected stations; and memory control means for controlling the memory means such that, when a call is made to a called station, the station identification data that is returned from the called station is stored in the memory means as one of the station identification data of the selected stations; wherein said communication control means rejects reception of the image data transmitted from the calling station when the calling station is not included in a list of stations stored the memory means.
Claim 2
Dependent Claim
307 words
A facsimile apparatus for transmitting and/or receiving image data to and from another facsimile apparatus in another station, comprising: communication control means connected with a communication line for establishing a connection with another station via the communication line, said communication control means sending station identification data to a calling station for identifying own station when a call is received from the calling station, said communication control means further receiving station identification data from a called station, when the facsimile apparatus has made a call to the called station, for identifying the called station; image data transmission and reception means for transmitting image data to the called station via the communication control means when a call is made to the called station and for receiving image data from the calling station via the communication control means when a call is received from the called station; image reading means for reading an image and producing the image data corresponding to the image, said image reading means transferring the image data to the image data transmission and reception means for transmission to the called station; image recording means supplied with the image data received from the calling station from the image data transmission and reception means for recording the image data on a recording sheet as a reproduced image; memory means for storing the station identification data of selected stations; and memory control means for controlling the memory means such that, when a call is made to a called station, the station identification data that is returned from the called station is stored in the memory means as one of the station identification data of the selected stations; wherein said communication control means rejects reception of the image data transmitted from the calling station when the calling station is not included in a list of stations stored the memory means.
Claim 3
Dependent Claim
119 words
A facsimile apparatus as claimed in claim 1 in which said memory control means controls the memory means such that the number of calls that have been received from the calling station in the past is stored in the memory means, said memory control means checks the memory means, when storing the station identification data of the called station, whether the memory means is full or not, and when the memory means is full, said memory control means controls the memory means such that the station identification data of the station that had sent facsimile transmission in the least frequency in the past is erased from the memory means before storing the station identification data of the called station.
Claim 4
Dependent Claim
84 words
A facsimile apparatus as claimed in claim 1 in which said memory control means comprises discrimination means for discriminating whether the facsimile apparatus in the called station is operating in a standard communication mode or in a non-standard communication mode based upon the station identification data that is returned from the called station, and said memory control means further stores mode information in the memory means, in addition to the station identification data, indicating communication mode of the facsimile apparatus in the called station.
Claim 5
Dependent Claim
61 words
A facsimile apparatus as claimed in claim 3 in which said memory means comprises a first field for storing the station identification data for stations in which the facsimile apparatus is operated in the standard communication mode and a second field for storing the station identification data for stations in which the facsimile apparatus is operated in the non-standard communication mode.
Claim 6
Dependent Claim
49 words
A facsimile apparatus as claimed in claim 3 in which, when receiving a call from a calling station, said communication control means reads out the mode information from the memory means and establishes the connection according to the communication mode used in the facsimile apparatus of the calling station.
Claim 7
Dependent Claim
38 words
A facsimile apparatus as claimed in claim 1 further comprising message output means for outputting a message, when the communication control means has rejected the reception of image data, indicating that there occurred a rejection of facsimile transmission.
Claim 8
Dependent Claim
29 words
A facsimile apparatus as claimed in claim 6 in which said message output means controls the image recording means such that the message is outputted on the recording sheet.
Claim 9
Dependent Claim
17 words
A facsimile apparatus as claimed in claim 1 in which said station identification data comprises numeric data.
Claim 10
Dependent Claim
17 words
A facsimile apparatus as claimed in claim 1 in which said station identification data comprises character data.
Claim 11
Dependent Claim
26 words
A facsimile apparatus as claimed in claim 1 in which said station identification data is the data defined in the CCITT recommendation for station identification purpose.
