Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 87 words
A data communicating apparatus comprising: means for performing data communication in a data communication mode; means for performing speech communication in a speech communicating mode; detection means for detecting a signal from a calling station indicating that the calling station is in a data communication mode; and control means for switching, during speech communication in the speech communication mode by said speech communication means, said data communicating apparatus from the speech communication mode to the data communication mode in response to the detecting of said detection means.
Claim 2
Dependent Claim 87 words
A data communicating apparatus comprising: means for performing data communication in a data communication mode; means for performing speech communication in a speech communicating mode; detection means for detecting a signal from a calling station indicating that the calling station is in a data communication mode; and control means for switching, during speech communication in the speech communication mode by said speech communication means, said data communicating apparatus from the speech communication mode to the data communication mode in response to the detecting of said detection means.
Claim 3
Dependent Claim 35 words
A data communicating apparatus according to claim 1, wherein said control means switches said data communicating apparatus from the speech communication mode to the data communication mode in response to the detection of the signal.
Claim 4
Dependent Claim 41 words
A data communicating apparatus according to claim 1, further comprising means for detecting a speech signal from the calling station, wherein said control means switches said data communicating apparatus to the speech communication mode upon the detection of the speech signal.
Claim 5
Dependent Claim 37 words
A data communicating apparatus according to claim 1, wherein said speech communication means includes memory means for storing a speech message and means for sending the speech message stored in said memory means to the calling station.
Claim 6
Dependent Claim 35 words
A data communicating apparatus according to claim 1, wherein said speech communication means includes a recording medium, wherein said speech communication means records a speech message sent from the calling station in said recording medium.
Claim 7
Dependent Claim 15 words
A data communication apparatus according to claim 5, wherein said recording medium comprises a memory.
Claim 8
Dependent Claim 48 words
A data communication apparatus according to claim 5, further comprising means for erasing the speech message recorded in said recording medium when said data communicating apparatus is in the speech communication mode upon switching said data communicating apparatus from the speech communication mode to the data communication mode.
Claim 9
Dependent Claim 101 words
A data communicating apparatus comprising: means for receiving a communication request from a calling station; means for performing data communication; means for performing speech communication; detection means for detecting a signal from the calling station indicating that the calling station is in a data communication mode; and control means for enabling said speech communication means and said data communication means, selectively, in response to the communication request and for switching between the performing of speech communication by said speech communication means and the performing of data communication by said data communication means in response to the detecting by said detection means.
Claim 10
Dependent Claim 101 words
A data communicating apparatus comprising: means for receiving a communication request from a calling station; means for performing data communication; means for performing speech communication; detection means for detecting a signal from the calling station indicating that the calling station is in a data communication mode; and control means for enabling said speech communication means and said data communication means, selectively, in response to the communication request and for switching between the performing of speech communication by said speech communication means and the performing of data communication by said data communication means in response to the detecting by said detection means.
Claim 11
Dependent Claim 58 words
A data communicating apparatus according to claim 8, wherein said control means enables said speech communication means in response to the communication request and switches from the performing of speech communication by said speech communication to the performing of data communication by said data communication means in response to the detection of the signal by said detection means.
Claim 12
Dependent Claim 36 words
A data communication apparatus according to claim 8, wherein said speech communication means includes a recording medium and wherein said speech communication means records a speech message sent from the calling station in said recording medium.
Claim 13
Dependent Claim 37 words
A data communicating apparatus according to claim 8, wherein said speech communication means includes memory means for storing a speech message and means for sending the speech message stored in said memory means to the calling station.
Claim 14
Dependent Claim 88 words
A facsimile apparatus comprising: means for receiving a communication request from a calling station; means for performing image data communication; means for performing speech communication; detection means for detecting a signal from the calling station representing a calling tone; control means for enabling said speech communication means in response to the communication request and for switching from the performing of speech communication by said speech communication means to the performing of image data communication by said image data communication means in response to the detection of the signal.
Claim 15
Dependent Claim 88 words
A facsimile apparatus comprising: means for receiving a communication request from a calling station; means for performing image data communication; means for performing speech communication; detection means for detecting a signal from the calling station representing a calling tone; control means for enabling said speech communication means in response to the communication request and for switching from the performing of speech communication by said speech communication means to the performing of image data communication by said image data communication means in response to the detection of the signal.
Claim 16
Dependent Claim 36 words
A facsimile apparatus according to claim 12, wherein said speech communication means includes memory means for storing a speech message and means for sending the speech message stored in said memory means to the calling station.
Claim 17
Dependent Claim 35 words
A facsimile apparatus according to claim 12, wherein said speech communication means includes a recording medium and wherein said speech communication means records a speech message sent from the calling station in said recording medium.
Claim 18
Dependent Claim 14 words
