Abstract

A facsimile machine uses cut sheets ofrecording paper of a predetermined size. If data to be recorded requires a cut sheet of paper of a size larger than the cut sheets of paper of the predetermined size set in the facsimile machine for use, then upon completion of recording part of the data on one of the cut sheets of recording paper of the predetermined size, a predetermined number of lines recorded at the end of the one of the cut sheets of paper are once again recorded at the beginning of the next following cut sheet of paper prior to recording of the following portion of the data to be recorded. In this manner, since that portion of data, which is divided between the two consecutive pages, is recorded twice in accordance with the present invention, no information will be lost even if the data to be recorded is significantly long.

Claims

1. A method for recording data in a facsimile machine using cut sheets of recording paper of a predetermined size, comprising the machine-implemented steps of:

determining whether or not a larger cut sheet of paper is required for recording said data than said predetermined size; and

recording a predetermined number of lines recorded at the end of a cut sheet of recording paper at the beginning of a next cut sheet of recording paper if a larger cut sheet of paper is required for recording said data than said predetermined size.

2. A recording system of a facsimile machine using cut sheets of recording paper of a predetermined size, comprising;

first storing means for storing data to be recorded;

second storing means for storing a predetermined amount of said data as transferred from said first storing means;

recording means connected to said first and second storing means for recording said data on one or more of said cut sheets of recording paper depending on the quantity of said data; and

control means for controlling the supply of said data among said first, second and recording means such that said data is supplied from said first storing means to said recording means and at the same time to said second storing means until completion of recording of one of said cut sheets of recording paper, and, then, that portion of said data not stored in said second storing means is first supplied to said recording means for recording on another of said cut sheets of recording paper prior to the supply of the following portion of said data from said first storing means to said recording means and also to said second storing means.

3. The system of claim 2 wherein said first storing means includes a buffer memory for storing said data to be recorded in its entirety.

4. The system of claim 3 wherein said second storing means includes a FIFO memory having a predetermined capacity.

5. The system of claim 4 wherein said control means includes a controller connected between said buffer memory and said FIFO memory, a selector connected between said FIFO memory and said recording means, and a bypass line connected between a line interconnecting said controller to said FIFO memory and said selector.

6. A facsimile machine for receiving data defining facsimile lines which collectively define a transmitted image and for recording a facsimile of the transmitted image on one or more cut sheets each of which has a selected image size, comprising:

means for receiving said data;

means responsive to the receiving means to record a facsimile of at least an initial portion of the transmitted image on a first cut sheet; and

means for (a) determining if the received data define a transmitted image whose size is greater than the image size of a first cut sheet and (b) in case the size of the transmitted image is greater, causing the recording means to record on the first cut sheet as much of the transmitted image as will fit thereon and for recording on a second cut sheet (i) a selected number of the facsimile lines already recorded at the end of the first cut sheet and (ii) at least a portion of the remainder of the transmitted image.

7. A fasimile machine as in claim 6 in which the determining and causing means comprises a memory which stores at least data defining said selected number of facsimile lines already recorded at the end of the first cut sheet.

8. A facsimile machine as in claim 7 in which the memory stores the number of facsimile lines which define an image corresponding to the image size of a cut sheet.

9. A facsimile machine as in claim 8 in which the memory is a FIFO memory by facsimile line.

10. A method of receiving data defining facsimile lines which collectively define a transmitted image and of recording a facsimile of the transmitted image on one or more cut sheets each of which has a selected image size, comprising:

receiving said data and recording a facsimile of at least an initial portion of the transmitted image on a first cut sheet; and

determining if the received data define a transmitted image whose size is greater than the image size of a first cut sheet and, in case the size of the transmitted image is greater, recording on the first cut sheet as much of the transmitted image as will fit thereon and recording on a second cut sheet (i) a selected number of the facsimile lines already recorded at the end of the first cut sheet and (ii) at least a portion of the remainder of the transmitted image.

11. A method as in claim 10 in which the determining and causing step comprises storing in a memory at least the data defining said selected number of facsimile lines already recorded at the end of the first cut sheet and reading the stored data and recording the beginning of the second cut sheet on the basis of the data read out of said memory.

12. A method as in claim 11 in which the step of storing data in said memory comprises storing in the memory the number of facsimile lines which define an image corresponding to the image size of a cut sheet.

13. A method as in claim 12 in which the storing step comprises storing in a FIFO memory.
