Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
133 words
A communication apparatus comprising: data communication means for performing data communication; speech communication means for performing speech communication; switching means, connected to said data communication means and speech communication means, for switching between operations of said data communication means and said speech communication means; time band setting means for setting a time band; ringing signal detection means for detecting a ringing signal from a calling party; and control means for controlling, after a predetermined period of time when said ringing signal detection means detects the ringing signal, said switching means such that said switching means switches from the operation of said speech communication means to the operation of said data communication means, wherein the predetermined period of time is varied in accordance with the time band set by said time band setting means.
Claim 2
Dependent Claim
133 words
A communication apparatus comprising: data communication means for performing data communication; speech communication means for performing speech communication; switching means, connected to said data communication means and speech communication means, for switching between operations of said data communication means and said speech communication means; time band setting means for setting a time band; ringing signal detection means for detecting a ringing signal from a calling party; and control means for controlling, after a predetermined period of time when said ringing signal detection means detects the ringing signal, said switching means such that said switching means switches from the operation of said speech communication means to the operation of said data communication means, wherein the predetermined period of time is varied in accordance with the time band set by said time band setting means.
Claim 3
Dependent Claim
62 words
An apparatus according to claim 1, further comprising operation detection means for detecting the operation of said speech communication means, and wherein, when said operation detection means detects the operation of said speech communication means within the predetermined period of time, said switching means does not switch the operation of said speech communication means to the operation of said data communication means.
Claim 4
Dependent Claim
29 words
An apparatus according to claim 1, wherein said time band setting means comprises memory means for storing a plurality of time bands and a timer means for counting time.
Claim 5
Dependent Claim
28 words
An apparatus according to claim 2, wherein said speech communication means includes a telephone handset, and said operation detection means detects an off-hook state of said telephone handset.
Claim 6
Dependent Claim
15 words
An apparatus according to claim 1, wherein said data communication means includes facsimile communication means.
Claim 7
Dependent Claim
129 words
A communication apparatus comprising: data communication means for performing data communication; speech communication means for performing speech communication; operation means for effecting operation of said apparatus; ringing signal detection means for detecting a ringing signal from a calling party; switching means, connected to said data communications means and to said speech communication means, for switching operations of said data communication means and said speech communication means; and control means, responsive to said operating means, for controlling, after a predetermined period of time when said ringing signal detection means detects the ringing signal, said switching means such that said switching means switches from the operation of said speech communication means to the operation of said data communication means, wherein the predetermined period of time is set by said operation means.
Claim 8
Dependent Claim
129 words
A communication apparatus comprising: data communication means for performing data communication; speech communication means for performing speech communication; operation means for effecting operation of said apparatus; ringing signal detection means for detecting a ringing signal from a calling party; switching means, connected to said data communications means and to said speech communication means, for switching operations of said data communication means and said speech communication means; and control means, responsive to said operating means, for controlling, after a predetermined period of time when said ringing signal detection means detects the ringing signal, said switching means such that said switching means switches from the operation of said speech communication means to the operation of said data communication means, wherein the predetermined period of time is set by said operation means.
Claim 9
Dependent Claim
39 words
An apparatus according to claim 6, wherein a time band corresponding to the predetermined period of time is set by said operation means, and said control means varies the predetermined period of time in accordance with the time band.
Claim 10
Dependent Claim
34 words
An apparatus according to claim 7, further comprising timer means for counting time, and wherein said control means selects the predetermined period of time in accordance with the time band set by the operation.
Claim 11
Dependent Claim
63 words
An apparatus according to claim 6, further comprising operation detection means for detecting the operation of said speech communication means, and wherein, when said operation detection means detects the operation of said speech communication means within the predetermined period of time, said switching means does not switch from the operation of said speech communication means to the operation of said data communication means.
Claim 12
Dependent Claim
15 words
An apparatus according to claim 6, wherein said data communication means includes facsimile communication means.
