Abstract
Abstract A facsimile machine uses a thermal print head for recording data on a roll of thermal sensitive recording paper. The roll of recording paper is wound around a core shaft on which a paper information memory is mounted. The facsimile machine includes a system controller in charge of overall control of the machine and the system controller reads the information stored in the paper information memory. The paper information to be stored includes a size, such as width and length, of the recording paper and a sensitivity of the recording paper. The facsimile machine may transmit the necessary data among the paper information to a transmitter. The facsimile machine may adjust the operating condition of the thermal print head in accordance with the sensitivity information read out of the paper information memory so as to insure production of an excellent recorded image.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A facsimile machine comprising: image reading means for optically reading an original; transmitting means for transmitting an original image read by said image reading means; receiving means for receiving data transmitted from a remote transmitter; recording means for recording said data received by said receiving means, wherein said recording means comprises a storage means for storing a supply of recording paper and further wherein said recording means is provided with an electronic paper information storing means which is part of said receiving paper storage means for electronically storing predetermined information regarding said recording paper stored in said recording means; and controlling means associated with each of the abovementioned means for controlling the overall operation of said facsimile machine, said controlling means being capable of reading said predetermined information stored in said electronic paper information storing means in controlling the overall operation of said facsimile machine.
Claim 2
Dependent Claim
145 words
A facsimile machine comprising: image reading means for optically reading an original; transmitting means for transmitting an original image read by said image reading means; receiving means for receiving data transmitted from a remote transmitter; recording means for recording said data received by said receiving means, wherein said recording means comprises a storage means for storing a supply of recording paper and further wherein said recording means is provided with an electronic paper information storing means which is part of said receiving paper storage means for electronically storing predetermined information regarding said recording paper stored in said recording means; and controlling means associated with each of the abovementioned means for controlling the overall operation of said facsimile machine, said controlling means being capable of reading said predetermined information stored in said electronic paper information storing means in controlling the overall operation of said facsimile machine.
Claim 3
Dependent Claim
22 words
