Abstract
Abstract Disclosed herein is a facsimile apparatus with a message-board function, which comprises a device for setting up a first supervisory period between the reception of a message and the execution of its associated procedure for thereby detecting whether or not a DTMF signal is inputted during the first supervisory period, a device for setting up a second supervisory period when a desired DTMF signal is detected during the first supervisory period for thereby detecting whether or not a DTMF signal is inputted during the second supervisory period, and a device for temporarily releasing the connection of a line when a group of DTMF signals indicative of a telephone number are detected during the second supervisory period for making calls by dialing with respect to the telephone office number, thereby transmitting the contents of a message to a called side.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A facsimile apparatus connectable to a remote apparatus, comprising: means for initiating a first supervisory period, and for detecting a DTMF signal received from the remote apparatus during the first supervisory period; means for initiating a second supervisory period in response to a detection of a predetermined DTMF signal during the first supervisory period, and for detecting a group of DTMF signals received from the remote apparatus during the second supervisory period; and means for terminating connection to the remote apparatus reception of a group of DTMF signals during the second supervisory period which correspond to a telephone number, for dialing the telephone number corresponding to the group of DTMF signals received during the second supervisory period, and for transmitting data to a party corresponding to the telephone number.
Claim 2
Dependent Claim
129 words
A facsimile apparatus connectable to a remote apparatus, comprising: means for initiating a first supervisory period, and for detecting a DTMF signal received from the remote apparatus during the first supervisory period; means for initiating a second supervisory period in response to a detection of a predetermined DTMF signal during the first supervisory period, and for detecting a group of DTMF signals received from the remote apparatus during the second supervisory period; and means for terminating connection to the remote apparatus reception of a group of DTMF signals during the second supervisory period which correspond to a telephone number, for dialing the telephone number corresponding to the group of DTMF signals received during the second supervisory period, and for transmitting data to a party corresponding to the telephone number.
Claim 3
Dependent Claim
27 words
The facsimile apparatus of claim 1, further comprising: means for receiving data from a calling side when no DTMF signal is received during the first supervisory period.
Claim 4
Dependent Claim
34 words
The facsimile apparatus of claim 1, further comprising: means for receiving data from a calling side when a DTMF signal received during the first supervisory period does not correspond to the predetermined DTMF signal.
Claim 5
Dependent Claim
34 words
The facsimile apparatus of claim 1, further comprising: means for receiving data from a calling side and for storing the data in memory when no DTMF signal is received during the second supervisory period.
Claim 6
Independent Claim
128 words
A method of operating a facsimile apparatus, comprising the steps of: establishing connection with a remote apparatus initiating a first supervisory period; detecting a DTMF signal received from the remote apparatus during the first supervisory period; initiating a second supervisory period in response to a detection of a predetermined DTMF signal during the first supervisory period; detecting a group of DTMF signals received from the remote apparatus during the second supervisory period; terminating connection with the remote apparatus in response to a reception of a group of DTMF signals during the second supervisory period which correspond to a telephone number; dialing the telephone number corresponding to the group of DTMF signals received during the second supervisory period; and transmitting data to a party corresponding to the telephone number.
Claim 7
Independent Claim
128 words
A method of operating a facsimile apparatus, comprising the steps of: establishing connection with a remote apparatus initiating a first supervisory period; detecting a DTMF signal received from the remote apparatus during the first supervisory period; initiating a second supervisory period in response to a detection of a predetermined DTMF signal during the first supervisory period; detecting a group of DTMF signals received from the remote apparatus during the second supervisory period; terminating connection with the remote apparatus in response to a reception of a group of DTMF signals during the second supervisory period which correspond to a telephone number; dialing the telephone number corresponding to the group of DTMF signals received during the second supervisory period; and transmitting data to a party corresponding to the telephone number.
Claim 8
Dependent Claim
26 words
The method claim 5, further comprising the step of: receiving data from a calling side when no DTMF signal is received during the first supervisory period.
Claim 9
Dependent Claim
33 words
The method claim 5, further comprising the steps of: receiving data from a calling side when a DTMF signal received during the first supervisory period does not correspond to the predetermined DTMF signal.
Claim 10
Dependent Claim
28 words
The method claim 5, further comprising the step of: receiving and storing data from a calling side when no DTMF signal is received during the second supervisory period.
