Abstract

PURPOSE:To reduce the waste in communication time and the line cost by using a data representing number of line error from a reception side during the communication control procedure and displaying and outputting the propriety of the line quality. CONSTITUTION:Prior to the transmission of a facsimile data at the communication side, a transmission control section 7 sends a training check signal (TCF) deciding the line state to the reception side via a MODEM 4. A picture signal error supervising section 5 supervises an error at the reception side and when an error takes place, an error number storage section 6 adds the number and gives the error number data to a reception control section 10 through the MO DEM 4 to send the data to a line state propriety deciding section 8 and the result of discrimination is displayed on a line state display device 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to a facsimile machine that determines the suitability of the line quality used.

[Conventional technology]

Conventionally, this type of facsimile machine transmits a training check signal (TCP") for determining line quality on the transmitting side according to communication control procedures, and then transmits the result determined by the number of line errors on the receiving side as a confirmation of reception readiness (CFR) or A train failure signal (FTT) is transmitted, and when receiving CFR, the transmitting side transmits an image signal, and when receiving FTT, it lowers the transmission speed by one level and retransmits TCP.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile machines do not have a means to check the line status on the sending side, and after the communication is completed, the operator on the receiving side checks the quality of the transmitted data.

are doing. For this reason, if the received recorded image that is reproduced is poor, there is a drawback that the communication time is wasted.

[Means to solve the problem]

A facsimile apparatus according to the present invention includes: a first means for outputting a count of errors counted based on a training check signal received from a line; a second means for transmitting the count value to the line; and a third means for determining whether the line quality is good or bad based on the counted value of and outputting the result for display.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. Before transmitting facsimile data on the transmitting side, the transmission control unit 7 transmits a training check signal (TCP) to the receiving side via the modem 4 to determine the line state. On the receiving side, TCP is received from the line through the modem 4, passed to the copier 3, and then sent to the image signal error monitoring unit 5.
Errors are monitored and when an error occurs, the error number accumulating section 6 adds up the number. When the reception of the determination data is completed, the receiving side passes the number of errors added by the error number accumulating section 6 to the transmission control section 7, and sends it to the transmitting side through the modem 4. Thereafter, on the receiving side, this error number data is passed through the modem 4 to the reception control section 10 and sent to the line condition quality determination section 8. Here, it is determined whether the line state is suitable for transmission or not, and the result of the judgment is displayed on the line state display 9. Note that the criteria for determining whether the line condition is good or bad can be arbitrarily set by an input operation.

〔Effect of the invention〕

As explained above, the present invention enables the operator on the transmitting side to save wasted communication time and line costs by displaying and outputting the appropriateness of the line quality using data indicating the number of line errors from the receiving side during the communication control procedure. There is an effect that it can be reduced.
