Abstract

PURPOSE:To reduce damage for document information due to the addition of communication control information by recording the communication control information at an upper or lower part having a little effective information of picture information to be printed onto recording paper. CONSTITUTION:The facsimile receiver is equipped with a communication control part 1, page memory 3 to store the picture information for one page decoded by a decoder 2 in a memory, and counters 6 and 8 to detect the upper or lower part having a lot of blank of the recording paper when the picture information is recorded. Further, a system control part 4 is provided to write the communication control information in the blank part of the memory 3 according to an instruction from a comparator 7, and a recording part 5 is provided to print out the picture information and the communication control information stored in the memory 3 to the recording paper. Therefore, while comparing whether a lot of black picture elements exist in the upper part or the lower part by the comparator 7, the system control part 4 writes the communication control information into the correspondent address of the memory having a little black picture elements, and the recording part 5 prints out the picture information and the communication control information read out of the memory 3 to the recording paper. Thus, the document information is not damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile receiver, and more particularly to a facsimile device that adds and records communication management information from a transmitting terminal to image information.

[Conventional technology]

In conventional facsimile receivers, CCITT Recommendation T
CIL (CallIdentifi) defined in 563
The recording function records communication management information such as the sender's terminal number, document number, page number of the sent document, communication date and time, etc. notified by the G4 facsimile communication protocol, and the image information set in advance on the receiver side. It is added to the top or bottom of the page and printed on recording paper.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile receiver always prints the communication management information on the upper or lower part of the preset reception recording side, so there is a problem that the communication management information is overlapped with the image information and the document information is damaged.

[Means to solve the problem]

The facsimile receiver of the present invention includes a communication control unit that outputs communication management information of a sending terminal and image information of a transmitted document in accordance with a communication control procedure, and a page memory that stores decoded image information corresponding to a hage in a memory. , a comparison means for detecting the upper or lower part of the recording paper with a large margin when the image information is recorded; means for writing the communication management information in the margin of the page memory according to an instruction from the comparison means; It has means for printing out the stored image information and communication management information on recording paper.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

This embodiment includes a communication control unit 1 that outputs communication management information of a sending terminal and image information of a sending document according to a communication control procedure;
A page memory 3 that stores image information for one page decoded by the decoder 2 in memory, and a counter 6 that detects the upper or lower part of the recording paper where there is a large margin when image information is recorded.
．． 8 and the comparator 7, the system control unit 4 writes communication management information in the margin of the page memory 3, and the recording unit prints out the image information and communication management information stored in the page memory 3 on recording paper. 5.

Next, the operation will be explained.

The communication control unit 1 performs communication according to the G4 facsimile communication protocol, and collects CI information such as terminal number information 1 and document number information.
Communication management information necessary for L recording is notified to the system control unit 4, and encoded image information is transferred to the decoder 2. The decoder 2 writes the decoded image information into the page memory 3 and notifies the system control unit 4 of the number of lines of the decoded image information of one page. System control unit 4
If the number of image information lines notified from the decoder 2 corresponds to the upper position of the CIL recording, the counter 6 counts the number of black pixels, and if the number corresponds to the lower position of the CIL recording, the counter 8 counts the number of black pixels. After the decoding of the image information for one page is completed, the system control unit 4 uses the comparator 7 to compare whether there are more black pixels in the upper part or the lower part, and communicates to the one with the smaller number of black pixels. The management information is written to the corresponding address of the page memory 3, and the recording section 5 prints out the image information and communication management information read out from the page memory 3 onto recording paper.

〔Effect of the invention〕

As explained above, the present invention records communication management information in the upper or lower part of the recording paper, where there is less effective image information, thereby reducing damage to document information due to the addition of communication management information. There is an effect.
