Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile apparatus having a so-called monitor copy function.

[Prior art]

When transmitting a document with light density characters or detailed graphics written on it using a facsimile machine, there are cases where you want to check how these will be reproduced. For this reason, there are facsimile machines equipped with a monitor copy function.

In this facsimile device, while the image information read by the reading section is being transmitted, the read image information is sent to its own recording section and the image is recorded. Therefore, each time a document is sent, the sending side retains one recorded image (monitor image).
will be obtained.

However, in such a facsimile device, even if an attempt was made to record the communication status at the time of transmitting the original on the recording paper, there was no space to do so. Therefore, a part of the image recording area is completely blanked out, and information such as the transmission date and time, recording density, and whether there is a retransmission request from the receiving side is printed in this part. Furthermore, in facsimile apparatuses that use long recording paper, a method has been adopted in which, after recording of an image is completed, data representing the communication state is recorded on a subsequent portion of the recording paper.

However, with the former facsimile device, it was not possible to monitor the image in the area where the frame was left open, and the original purpose of the monitor could not be achieved in some cases. Furthermore, the latter facsimile apparatus not only cannot be used in cut paper feeding type facsimile apparatuses, but also has the problem that the recording paper becomes uneconomical.

[Purpose of the invention]

In view of these circumstances, it is an object of the present invention to provide a facsimile device that can record a monitor image of an original and information representing the communication status on recording paper of at least the same size as the original without interfering with each other. purpose.

[Structure of the invention]

The present invention includes a reading unit that reads image information on a document, a transmitting unit that transmits the read image information, and a character generating unit that converts predetermined information representing the communication state at the time of transmitting the image information into a character pattern. Then, the image information transmitted by the transmitter is thinned out line by line and recorded in a compressed form in the sub-scanning direction. The facsimile device is equipped with a monitor unit that prints information representing the communication status.

〔Example〕

The present invention will be explained in detail with reference to Examples below.

FIG. 1 shows the facsimile apparatus of this embodiment. The reading unit 11 uses an image sensor to sequentially read image information on a document line by line. The image signal 12 obtained in this manner is supplied to both the transmitter 13 and the monitor 14 after being binarized. After compressing the signal, the transmitter 13 modulates the signal and sends it to the communication line 15.

In the monitor section 14, the frequency of the clock pulse generated for each scan of the image sensor is divided by half, and the gate is controlled using this frequency to thin out the image signal 12 by one line into two lines. The monitor original signal 16 obtained in this way is sent to the recording section 17.
is supplied to In the recording section 17, the sub-scanning of the recording paper is controlled using a clock pulse whose frequency is similarly divided into 1/2, and a monitor image is recorded.

FIG. 2 shows the monitor image obtained in this manner in comparison with the original. A monitor image is obtained on the recording paper 19 by thinning out every two scanning lines of the original document 18. This makes it possible to accurately monitor the print density of light originals and the like. Although the scanning line density is reduced by half, the image reproducibility of the entire document can be checked almost completely.

When the monitor image of the original has been created in this way, the image information "A" on the original 18 is reproduced in a compressed form on the upper half 21 of the recording paper 19, as shown in FIG. There is. Lower half 2 of recording paper 19
Monitoring character information "B, C, . . ." output from the character generator 23 is recorded in the blank space of No. 2. The character generator 23 generates a character pattern based on the transmission side communication status information 24 obtained from the transmission side facsimile device. This is then scanned line by line and supplied to the recording unit 17 as a monitoring communication status signal 25. The transmission side communication status information 24 includes the date and time of transmission, the destination telephone number, the pressed state of the image quality control button, and the like.

The facsimile apparatus of this embodiment can also record the communication results sent from the receiving side on the lower half 22 of the recording paper. That is, the receiving unit 26 decodes the control signal sent from the facsimile device (not shown) on the receiving side when the transmission of the original is completed, and converts predetermined control information such as a request for retransmission of the original into the communication status information on the receiving side. 27 to the character generator 23. The character generator 23 generates a character pattern based on this, and supplies it to the recording section 17 as the above-mentioned monitoring communication status signal 25.

In the embodiment described above, the image information is uniformly thinned out line by line, but it is also possible to completely reproduce the image information only in a desired sub-scanning section.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to record a monitor image of the entire document and information representing the communication state on recording paper of the same size as the document without interfering with each other. In addition, since both the monitor image and the information representing the communication status can be recorded on recording paper of the same size as the original, such as cut paper, the unification of the recording paper size makes it easier to file the recording paper. There is.
