Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 105 words
An image communication system, comprising: a plurality of communication terminals each including speech communication means for effecting speech communication and reading means for reading an image; and line control means for selectively connecting said communication terminals to at least one communication line, wherein said line control means includes input means for inputting image data from each of said terminals, means for performing a communication procedure of image data, and send means for sending the image data input from said input means to said communication line in accordance with the communication procedure, said line control means being adapted to send image data from said plural terminals.
Claim 2
Dependent Claim 105 words
An image communication system, comprising: a plurality of communication terminals each including speech communication means for effecting speech communication and reading means for reading an image; and line control means for selectively connecting said communication terminals to at least one communication line, wherein said line control means includes input means for inputting image data from each of said terminals, means for performing a communication procedure of image data, and send means for sending the image data input from said input means to said communication line in accordance with the communication procedure, said line control means being adapted to send image data from said plural terminals.
Claim 3
Dependent Claim 21 words
An apparatus according to claim 1, further comprising means for receiving the image data and means for recording the image data.
Claim 4
Dependent Claim 36 words
An apparatus according to claim 2, wherein said receiving means includes a memory for storing the image data, the image data being recorded by said recording means after the image data is stored in said memory.
Claim 5
Dependent Claim 37 words
An apparatus according to claim 1, wherein said transmitting means includes a memory for storing the image data, the image data being transmitted after the image data from one of said terminals is stored in said memory.
Claim 6
Dependent Claim 27 words
An apparatus according to claim 4, wherein said transmitting means transmits the image data from said memory in accordance with a transmission command from said one terminal.
Claim 7
Dependent Claim 91 words
An image communication system, comprising: a plurality of speech communication terminals each having reading means for reading an image; and a line exchanging unit for connecting said plural speech communication terminals to plural communication lines; wherein said line exchanging unit includes means for performing a communication procedure of image data, and transmitting means for transmitting image data from said speech communication terminals in accordance with the communication procedure, and wherein said communication procedure means starts the communication procedure in response to a transmission command from one of said speech communication terminals.
Claim 8
Dependent Claim 91 words
An image communication system, comprising: a plurality of speech communication terminals each having reading means for reading an image; and a line exchanging unit for connecting said plural speech communication terminals to plural communication lines; wherein said line exchanging unit includes means for performing a communication procedure of image data, and transmitting means for transmitting image data from said speech communication terminals in accordance with the communication procedure, and wherein said communication procedure means starts the communication procedure in response to a transmission command from one of said speech communication terminals.
