Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 108 words
An apparatus being adaptable to a protocol standard for transmitting and receiving data, said standard defining a first operation mode, a second operation mode, a first protocol type, a second protocol type, and a response protocol type, said apparatus comprising: means for detecting said first protocol type; means for detecting said second protocol type; means for setting said apparatus in said first operation mode and said second operation mode in response to detections of said first protocol type and said second protocol type; and means for selecting said responsive protocol type in response to said first operation mode and said second operation mode set by said setting means.
Claim 2
Independent Claim 108 words
An apparatus being adaptable to a protocol standard for transmitting and receiving data, said standard defining a first operation mode, a second operation mode, a first protocol type, a second protocol type, and a response protocol type, said apparatus comprising: means for detecting said first protocol type; means for detecting said second protocol type; means for setting said apparatus in said first operation mode and said second operation mode in response to detections of said first protocol type and said second protocol type; and means for selecting said responsive protocol type in response to said first operation mode and said second operation mode set by said setting means.
Claim 3
Dependent Claim 29 words
The apparatus of claim 1, wherein said setting means further comprises: means for determining a time interval between detections of said first protocol type and said second protocol type.
Claim 4
Dependent Claim 29 words
The apparatus of claim 2, wherein said setting means further comprises: means for indicating said first operation mode and said second operation mode in response to said determining means.
Claim 5
Dependent Claim 31 words
The apparatus of claim 3, said apparatus further comprises: means for detecting data type; and means for decoding data according to said data type detected by said data type detecting means.
Claim 6
Dependent Claim 21 words
The apparatus of claim 3, wherein: said first operation mode is non-handshake mode, and said second operation mode is handshake mode.
Claim 7
Dependent Claim 30 words
The apparatus of claim 5, wherein: said first protocol type is a TOP protocol, said second protocol type is a BOT protocol, and said response protocol is a HSK protocol.
Claim 8
Dependent Claim 57 words
The apparatus of claim 6, wherein: said TOP protocol includes information indicating image data type, said BOT protocol includes information confirming said data type, and said HSK protocol includes information indicating whether a facsimile machine at receiving end is ready and whether the information in said TOP protocol is compatible with said facsimile at the receiving end.
Claim 9
Dependent Claim 12 words
The apparatus of claim 6, wherein said standard is MIL-STD-188-161 B&C standard.
Claim 10
Dependent Claim 70 words
The apparatus of claim 2, wherein: said setting means sets said apparatus in said first operation mode when said second protocol type is detected within a predetermined time interval after said first protocol type has been detected, and said setting means sets said apparatus in said second operation mode when said second protocol type is not detected within said predetermined time interval after said first protocol type has been detected.
Claim 11
Dependent Claim 21 words
The apparatus of claim 9, wherein: said first operation mode is non-handshake mode, and said second operation mode is handshake mode.
Claim 12
Dependent Claim 30 words
The apparatus of claim 10, wherein: said first protocol type is a TOP protocol, said second protocol type is a BOT protocol, and said response protocol is a HSK protocol.
Claim 13
Dependent Claim 58 words
The apparatus of claim 11, wherein: said TOP protocol includes information indicating image data type, said BOT protocol includes information confirming said data type, and said HSK protocol includes information indicating whether a facsimile machine at the receiving end is ready and whether the information in said TOP protocol is compatible with said facsimile at the receiving end.
Claim 14
Dependent Claim 13 words
The apparatus of claim 11, wherein said protocol standard is MIL-STD-188-161 B&C standard.
Claim 15
Independent Claim 107 words
A method of operating an apparatus adaptable to a protocol standard for transmitting and receiving image data, said standard defining a first operation mode, a second operation mode, a first protocol type, a second protocol type, and a response protocol type, said method comprising the steps of: detecting said first protocol type; detecting said second protocol type; setting said apparatus in said first operation mode and said second operation mode in response to detections of said first protocol type and said second protocol type; and selecting said response protocol type in response to said first operation mode and said second operation mode set by said setting step.
Claim 16
Independent Claim 107 words
A method of operating an apparatus adaptable to a protocol standard for transmitting and receiving image data, said standard defining a first operation mode, a second operation mode, a first protocol type, a second protocol type, and a response protocol type, said method comprising the steps of: detecting said first protocol type; detecting said second protocol type; setting said apparatus in said first operation mode and said second operation mode in response to detections of said first protocol type and said second protocol type; and selecting said response protocol type in response to said first operation mode and said second operation mode set by said setting step.
Claim 17
Dependent Claim 30 words
The method of claim 14, wherein said setting step further comprises the step of: determining a time interval between detection of said first protocol type and said second protocol type.
Claim 18
Dependent Claim 30 words
The method of claim 15, wherein said setting step further comprises the step of: indicating said first operation mode and said second operation mode in response to said determining means.
Claim 19
Dependent Claim 23 words
The method of claim 16, wherein: said first operation mode is a non-handshake mode, and said second operation mode is a handshake mode.
Claim 20
Dependent Claim 30 words
The method of claim 17, wherein: said first protocol type is a TOP protocol, said second protocol type is a BOT protocol, and said responsive protocol is a HSK protocol.
Claim 21
Dependent Claim 57 words
The method of claim 18, wherein: said TOP protocol includes information indicating image data type, said BOT protocol includes information confirming said data type, and said HSK protocol includes information indicating whether a facsimile machine at receiving is ready and whether the information in said TOP protocol is compatible with the said facsimile at the receiving end.
Claim 22
Dependent Claim 13 words
The method of claim 19, wherein said protocol standard is MIL-STD-188-161 B&C standard.
