Abstract

An image communications apparatus divides a long-size original image into a standard-size image portion and a remaining image portion in a transmission mode, and in recording a received long-size original image divides it into a standard-size image portion and a remaining image portion in a reception mode. When the apparatus divides the long-size original image into a standard-size image, a portion of the original image at which division is performed is set to be a blank portion by controlling information of the original image so that partial split image in a printed paper can be prevented.

Claims

1. An image communications apparatus comprising:

first sensing means for sensing whether or not the length of an original image is longer than a predetermined length;

second sensing means for sensing a blank portion of the original; and

processing means for dividing the original image utilizing said blank portion as a border when the length of the original image is sensed to be longer than the predetermined length.

2. An image communications apparatus according to claim 1, wherein said processing means includes a transmission means which divides the original image utilizing said blank portion as a border and transmits data of the divided original images.

3. An image communications apparatus according to claim 2, further including reading means for reading the original image.

4. An image communications apparatus according to claim 1, wherein said processing means is recording means which divides the original image utilizing said blank portion as a border and records the divided original images.

5. An image communications apparatus according to claim 4, further including demodulator means for demodulating a signal representative of said original image.

6. An image transmitting apparatus comprising:

reading means for reading an original image;

transmitting means for transmitting an image signal read out by said reading means;

sensing means for sensing whether or not the length of said original image is longer than a predetermined length;

blank portion sensing means for sensing the presence of a blank portion within said predetermined length of said original image; and

stopping means for temporarily stopping transmission of said transmitting means when the length of said original image is sensed to be longer than the predetermined length.

7. An image transmitting apparatus according to claim 6, wherein said blank portion sensing means senses a blank portion in a limited area within said predetermined length of said original image.

8. An image transmitting apparatus according to claim 6, wherein said stopping means is operable to stop the reading operation of said reading means at said blank portion.

9. An image receiving apparatus comprising:

receiving means for receiving a signal representative of an original image;

sensing means for sensing whether or not the length of the image represented by the received image signal is longer than a predetermined length;

blank portion sensing means for sensing a blank portion within said predetermined length of the received image; and

recording means for dividing the original image utilizing said blank portion as a border and for respectively recording the divided original images on separate recording members when the length of said received original image is sensed to be longer than the predetermined length.

10. An image receiving apparatus according to claim 9, wherein said blank portion sensing means senses a blank portion in a predetermined area within said predetermined length of the original image.

11. An image receiving apparatus according to claim 9, further including memory means for temporarily storing said received image signal for a predetermined number of scanning lines.
