Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A change-over system for automatically answering telephony and facsimile reception in a facsimile apparatus capable of connecting an automatic answering telephone set thereto, characterized in that at the time point when a terminating party side sends out a circuit connecting signal and a digital identification signal to an originating party side, and subsequently sends out a group identification signal, ringing of the automatic answering telephone set at the terminating party side is begun, and at the same time, the time interval until the automatic answering telephone set is brought into an off-hook state from the beginning of the ringing is detected, thereby allowing the time of the beginning of the ringing of the automatic answering telephone set to be altered by a correction function.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
132 words
A facsimile apparatus comprising: a main body including a processing unit; a network control unit, separate from the main body, operably connecting the main body to a telephone circuit, an additional telephone set and an automatic answering telephone set having a recording device controlled by the automatic answering telephone set, the network control unit including relay switches for selectively connecting the main body, the additional telephone set, and the automatic answering telephone set to the telephone circuit, and initialization means for initializing the automatic answering telephone set after a predetermined period; and correction means for reducing the predetermined period in response to a previous call wherein the additional telephone was not answered and a digital command signal was not received prior to a sending of a predetermined number of digital identification signals.
