Abstract
Abstract In an apparatus that has a main power supply and a sub-power supply and that halts a main power supply in the standby state, the main power supply is turned on for an incoming call for facsimile communication, while the main power supply is not turned on for an incoming call for speech communication. Therefore, the unnecessary turning on and off of the main power supply can be prevented. When the DRPD (Distinguish Ringing Pattern Detect) service is provided, a plurality of telephone numbers are assigned to a single communication line, and a plurality of call signals whose pattern differ are employed for receiving calls. When one of these telephone numbers is used for facsimile and another telephone number is used for a telephone, an incoming call can be identified as being either for facsimile or for telephone by distinguishing between the patterns of the call signals. When the pattern of the call signal is for facsimile, the main power supply is turned on to perform data communication. When the pattern of the call signal is for telephone, the main power supply is not turned on.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
A facsimile machine comprising: communication means for performing data communication; power supply means, which is capable of being turned on and off, for supplying power to said communication means; identification means for identifying plural types of call signals that are transmitted across a communication line; and control means for turning on said power supply means in consonance with an identification result that is provided by said identification means.
Claim 2
Dependent Claim
26 words
A facsimile machine according to claim 1, wherein said plural types of call signals are call signals that are used in Distinguish Ringing Pattern Detect service.
Claim 3
Dependent Claim
61 words
A facsimile machine according to claim 1, further comprising setting means for setting a type of a call signal across data communication, wherein, when a call signal through said communication line is identified by said identification means to be said call signal for data communication that is set by said setting means, said control means turns on said power supply means.
Claim 4
Dependent Claim
72 words
A facsimile machine according to claim 3, further comprising speech communication means for performing speech communication, wherein said setting means sets a type of a call signal for speech communication and wherein, when a call signal across said communication line is identified by said identification means to be said call signal for speech communication that is set by said setting means, said control means does not turn on said power supply means.
Claim 5
Dependent Claim
76 words
A facsimile machine according to claim 4, further comprising second setting means for setting no-ringing reception during which, upon the receipt of an incoming call, an operator is not notified of said incoming call by ringing, wherein, when said no-ringing reception is set in said second setting means, said control means does not respond to the result obtained by said identification means and turns on said power supply means at the time of said incoming call.
Claim 6
Dependent Claim
144 words
A facsimile machine comprising: a main power supply, which is capable of being turned on and off, for supplying power to said facsimile machine; a first controller for receiving power from said main power supply; a second controller for controlling an ON/OFF state of said main power supply and a console unit that performs key input and a display, and for monitoring a call signal from a switchboard; and a sub-power supply for supplying power to said second controller, whereby said main power supply is turned off in a standby state and whereby a type of key input is determined, and as a result, when it is necessary for said first controller to be operated, said second controller turns on said main power supply to activate said first controller, while when said first controller need not be operated, said second controller manages key-input data.
Claim 7
Dependent Claim
34 words
A facsimile machine according to claim 6, wherein, when said first controller begins to operate, said second controller transfers, to said first controller, said key-input data that are managed while in the standby state.
Claim 8
Dependent Claim
116 words
A facsimile machine comprising: communication means for performing data communication; power supply means, which is capable of being turned on and off, for supplying power to said communication means; identification means for identifying a telephone number at a calling side that is reported, together with a call signal, across a communication line; setting means for setting a telephone number of a call originator that desires communication; and control means for employing an identification result that is provided by said identification means and a setup that is provided by said setting means to turn on said power supply means when a telephone number that is reported across said communication line is a telephone number that is set.
Claim 9
Dependent Claim
63 words
A facsimile machine according to claim 8, further comprising an auto answering/recording function that has a personal absence/presence select means that selectively sets an absence mode and a presence mode, wherein, when said absence mode is selected, said control means turns on said power supply means in consonance with the detection of a call signal, regardless of said identification result and said setup.
Claim 10
Dependent Claim
191 words
A facsimile machine comprising: speech communication means for performing speech communication; data communication means for performing data communication; connection means for connecting communication lines; power supply means, which is capable of being turned on and off, for supplying power to said data communication means and said connection means; first detection means for detecting a call signal across said communication line; control means for turning on said power supply means in consonance with said call signal that is detected by said first detection means; second detection means for determining whether or not an operator is permitted to use said speech communication means; and control means for determining whether or not a terminal at which a call for which said connection means effects a connection with said communication line is a data communication terminal such as a fax communication terminal or a speech communication terminal, and for, when said call originates at said speech communication terminal and when said second detection means determines that said operator is permitted to employ said speech communication means, turning off said power supply means after said connection means connects said communication line to said speech communication means.
Claim 11
Dependent Claim
21 words
A facsimile machine according to claim 10, wherein said second detection means detects an off-hook state of said speech communication means.
Claim 12
Dependent Claim
28 words
A facsimile machine according to claim 10, wherein said control means turns off said power supply means in consonance with a control signal from said speech communication means.
