Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a communication device, and more particularly, to a communication device which inputs / outputs predetermined data via a communication line according to a predetermined communication procedure and outputs data via recording means. It is about.

[Prior Art] The color (ground) of recording paper of a conventional facsimile apparatus is basically one color.

Here, basically, it means that, for example, if an A4 cassette and a B4 cassette are provided, and if the colors of the recording paper set in the A4 cassette and the B4 cassette are changed, recording on a plurality of colors of recording paper can be performed. means.

However, no facsimile apparatus that changes the color of the recording paper to be recorded according to the communication management information (particularly focusing on the presence or absence of an error) and the received information has not been proposed.

[Problems to be Solved by the Invention] However, in the above conventional example, the color of the recording paper to be recorded is not changed according to the communication management information (particularly, attention is paid to the presence or absence of an error) and the received information. Recording is performed on white recording paper.

Recently, the communication volume of facsimile transmission has increased, and the memory function has been enhanced, so that the operator has no choice but to store data in the memory.

For example, at the time of memory transmission or broadcast transmission, an error occurs and a communication result report is output.

However, since the amount of communication is large and the color of the recording paper is the same as the received information, errors have been missed and business opportunities have been missed.

An object of the present invention is to solve the above problems and to provide a communication device capable of selecting an appropriate color of recording paper according to the operation state of the device.

[Means for Solving the Problems] In order to solve the above problems, according to the present invention, a recording unit that performs recording using at least one of three different colors of recording paper, and a normal reception by the recording unit And the first error report if an error occurs while operating as a transmitter,
Also, when operating as a receiver, when an error occurs, it has control means for recording a second error report, the color of the recording paper for recording the normally received data,
The recording unit is controlled such that the color of the recording paper for recording the first error report is different from the color of the recording paper for recording the second error report.

The color, the color of the recording paper for recording the first error report to be recorded according to the occurrence of an error when operating as a transmitter, and the second color to be recorded according to the occurrence of an error when operating as a receiver Since the recording means is controlled so that the color of the recording paper for recording the error report 2 is different from the color of the recording paper, the normally received data and the error report recorded when an error occurs are recorded on the recording paper. By making the colors different, it is possible to draw the user's attention to the occurrence of an error. In the case of an error, the transmission error report and the reception error report have different colors. Since recording is performed using recording paper, the user can clearly confirm at a glance whether the error is related to transmission or reception, and recording can be performed even in an environment with a large amount of communication. There is an excellent effect that the user does not lose sight of important error information at the output position, and the nature of the error information (whether a transmission error or a reception error) can be clearly confirmed at a glance.
