Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A recording apparatus comprising: first sheet feeding means for feeding a large size of recording sheet; first detection means for detecting the presence or absence of a sheet in said first sheet feeding means; second sheet feeding means for feeding a small size of recording sheet; second detection means for detecting the presence or absence of a sheet in said second sheet feeding means; communication means for data communication; recording means for recording image data received from said communication means or communication monitoring data; and selection means for selecting either one of said first and second sheet feeding means, in the recording of the received image data, in accordance with size data transmitted to said communication means prior to said image data, and for selecting said second sheet feeding means in the recording of said communication monitoring data, said selection means selecting said first sheet feeding means in the recording of said communication monitoring data when said second detection means detects the absence of a sheet and said first detection means detects the presence of a sheet.
Claim 2
Dependent Claim
177 words
A recording apparatus comprising: first sheet feeding means for feeding a large size of recording sheet; first detection means for detecting the presence or absence of a sheet in said first sheet feeding means; second sheet feeding means for feeding a small size of recording sheet; second detection means for detecting the presence or absence of a sheet in said second sheet feeding means; communication means for data communication; recording means for recording image data received from said communication means or communication monitoring data; and selection means for selecting either one of said first and second sheet feeding means, in the recording of the received image data, in accordance with size data transmitted to said communication means prior to said image data, and for selecting said second sheet feeding means in the recording of said communication monitoring data, said selection means selecting said first sheet feeding means in the recording of said communication monitoring data when said second detection means detects the absence of a sheet and said first detection means detects the presence of a sheet.
Claim 3
Dependent Claim
55 words
A recording apparatus according to claim 1, wherein said selection means is adapted, in the recording of the received image data, if either said first or second detection means detects the absence of the recording sheet in either sheet feeding means selected in accordance with said size data, to select the other sheet feeding means.
Claim 4
Dependent Claim
47 words
A recording apparatus according to claim 2, wherein said selection means is adapted to control said recording means so that if said other detection means detects the absence of the recording sheet in said other sheet feeding means, the recording of the received image data is interrupted.
Claim 5
Dependent Claim
47 words
A recording apparatus according to claim 1, wherein said selection means is adapted, if said first detection means detects the absence of a sheet in said first sheet feeding means, to control said recording means so as to interrupt the recording operation of the communication monitoring data.
Claim 6
Dependent Claim
17 words
A recording apparatus according to claim 1, further comprising memory means for storing and communicating monitoring data.
Claim 7
Dependent Claim
184 words
A recording apparatus comprising: first and second sheet feeding means for storing and feeding different sized recording sheets, respectively; first detection means for detecting the size of the recording sheets stored in said first sheet feeding means; second detection means for detecting the size of the recording sheets stored in said second sheet feeding means; communication means for data communication; recording means for recording image data received by said communications means or communication monitoring data; and size detection means for detecting the size of the recording sheets set in said first and second sheet feeding means; and selection means for selecting, in the recording of said image data, either one of said first or said second sheet feeding means in accordance with (1) size data transmitted to said communication means prior to said image data, and (2) output data of said first and second detection means, and for selecting, in the recording of the communication monitoring data, either one of said first or said second sheet feeding means which is detected to have a smaller size sheet by said first and second detection means.
Claim 8
Dependent Claim
184 words
A recording apparatus comprising: first and second sheet feeding means for storing and feeding different sized recording sheets, respectively; first detection means for detecting the size of the recording sheets stored in said first sheet feeding means; second detection means for detecting the size of the recording sheets stored in said second sheet feeding means; communication means for data communication; recording means for recording image data received by said communications means or communication monitoring data; and size detection means for detecting the size of the recording sheets set in said first and second sheet feeding means; and selection means for selecting, in the recording of said image data, either one of said first or said second sheet feeding means in accordance with (1) size data transmitted to said communication means prior to said image data, and (2) output data of said first and second detection means, and for selecting, in the recording of the communication monitoring data, either one of said first or said second sheet feeding means which is detected to have a smaller size sheet by said first and second detection means.
Claim 9
Dependent Claim
19 words
A recording apparatus according to claim 6, wherein said communication monitoring data are for monitoring functions of the apparatus.
