Abstract

PURPOSE:To decrease the danger of occurrence of a memory overflow by reduc ing to the picture information in size smaller than a read original size when it is judged that the allowance is absent at the remaining quantity of a picture information storing memory. CONSTITUTION:A control part 5 calculates a memory capacity necessary to an original accumulation and compares the result with the empty capacity of a picture information storing memory 3 by means of the number of sheets of an original, a line density, address information inputted by an operating part 1 and the capability of an opponent device obtained by an opponent device capability information file 4. At such a time, when the latter is larger than the former, the accumulating and storing are executed by the designated mode, when the former is larger than the latter, the read picture information is reduced to the A4 size, instruction is issued to a picture information compressing part 6 so as to compress the picture information and the compressed picture information is stored into the picture information storing memory 3.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a facsimile device.

[Conventional technology]

Conventionally, with this type of facsimile machine, if the other party's device has the recording ability to directly record in the original size of the sending station,
Accumulates the image size of the sent original without reducing it,
It was sending.

[Problem that the invention seeks to solve]

The conventional facsimile machine described above stores the read image information as it is in the image information memory without considering the remaining amount of memory that can be stored, and therefore cannot store the entire input document in the image information memory. This method has the disadvantage that not only does it cause a memory overflow before the image information is completed, making it impossible to transmit all documents at once, but also imposes restrictions on operations that involve storing image information in the memory.

[Means for solving problems]

The facsimile device of the present invention is a facsimile device that is capable of sequential broadcast transmission and has a document reading section, an image information compression section that reduces the image size of read image information, and an image information storage memory that accumulates and stores the image information. If it is determined that there is not enough space left in the image information storage memory considering the linear density and number of originals to be sent, set an original of a size that can be recorded in the main scanning direction of the recipient device. Even if the document size is smaller than the size of the transmitted document, the device has means for storing and transmitting the image information smaller than the size of the transmitted document.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention.

1 is an operation section including a display for prompting operations and a switch for accepting input; 2 is a document reading section capable of reading documents of B4 size or larger; 3 is an image information storage memory for accumulating and storing image information; 4 is for communication history. 5 is a control unit that determines the mode of image information to be stored in the memory 3; 6 is an image information compression unit that compresses the image information; 7 is an image information compression unit that compresses the image information; A communication control section 8 controls the communication procedure, and is a line control section that performs outgoing and incoming call control for the line.

The control unit 5 calculates the memory capacity required for document storage based on the number of originals, linear density, and destination information inputted through the operation unit 1 and the capabilities of the partner device obtained from the partner device capability information file 4. It is compared with the free capacity of the image information storage memory 3. At this time, if the latter is larger than the former, it is accumulated and stored in the specified mode, but if the former is larger than the latter, the read image information is reduced to A4 size and the image is stored. An instruction is given to the image information compression section 6 to compress the information, and the compressed image information is stored in the image information storage memory 3.

Wait for the completion of accumulation and storage before communicating with the partner device.

〔Effect of the invention〕

As explained above, in the present invention, if it is determined that there is not enough remaining capacity in the image information storage memory considering the linear density and number of originals to be transmitted, By reducing the image information, the amount of image information is compressed, and the amount of image information storage memory consumed can be reduced compared to reading the raw information iK, so the risk of memory overflow 70- is reduced, and the image information storage memory is reduced. This has the effect of reducing operational constraints associated with storage in memory.
