Abstract

PURPOSE:To avoid useless transmission by providing a function returning the state of receiver equipment and the state of a faulty equipment such as paper jamming of reception paper to a sender equipment. CONSTITUTION:The content of an equipment status register 11 is sent to an encoder 12, and the status is coded such as '01' for paper jamming and '02' for paper shortage. The coded signal is sent back to a sender side via a transmission multiplex circuit 13. When the coded signal is, e.g. '01' the sender side sets a bit relating to 'paper jamming' and when '02', a bit relating to 'paper shortage' is set. Then the content of a reception status register 23 and a transmission number register is sent to an output means 25 and the content is displayed. Thus, the sender side recognizes a fault state of the equipment of the receiver side.

Description

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

[Conventional technology]

Conventionally, this type of facsimile transmitter/receiver only performs one-sided communication to the receiver, and no information is communicated from the receiver side. The sending side cannot distinguish between a non-operating case and a busy case due to being in use.

[Problem to be solved by the invention]

In the above-mentioned conventional facsimile transceiver, the transmitter side cannot identify the status of the receiver device, so even if the receiver is malfunctioning, the sender recognizes that it is simply being used and repeats the sending operation several times. It is inefficient to do this. Also, when transmitting automatically, there is a drawback that the transmitter is occupied.

[Means to solve the problem]

The facsimile transceiver of the present invention includes a means for detecting and storing the details of a fault in the device, a means for transmitting a fault code coded for each previous fault content to a receiving line, and a means for decoding the fault code received from the line. and means for outputting and displaying the details of the fault in response to the decoded received fault code.

〔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. The area surrounded by the dashed line is the object of the present invention.

Reference numeral 1l denotes a device status register that stores the status of a transmitter/receiver failure, paper jam, etc. 12 is an encoder for encoding according to the bit position of the i-position status register 11, that is, the status of the transmitter/receiver; 13 is an output of the encoder 12 that collects the signals from the transmitting circuit having the normal function of the fax transmitter/receiver. transmission collective circuit. 21 transmits the received signal to a facsimile transmission circuit and a decoder circuit 22
Receiving separation circuit for separating into. A decoder 22 decodes the status of the device on the other side (in this case, the information receiving side) from the encoded and received signal. 23 is a reception status register for storing the state decoded by the decoder. 24 is a sending number register that stores the number of the person to whom you want to send a fax when you dial it. 25
is a means for displaying the contents of the reception status register 23 and the contents of the transmission number register 24 (for example, on a liquid crystal display) or an output means for outputting them on the reception sheet. 31 is encoder 1 during normal facsimile transmission and reception operations.
2. A control circuit for performing control such as preventing the decoder 22 from operating.

Next, the operation of this embodiment will be explained. It is assumed that both the transmitter and receiver have the same functions, and that one's transmission line is connected to the other party's reception line, and the other party's transmission line is connected to one's own reception line. When dialing is performed from the sending side, the dialed number is stored in the sending number register 24. At the same time, although it is outside the scope of the present invention, when a facsimile signal is sent from the facsimile transmission circuit to the other party via the transmission aggregation circuit 13 and the receiver of the other party is out of order for some reason, or when the received paper is When reception becomes impossible due to a blockage or the like, that state is stored in the device status register l1. The contents of device status register l1 are sent to encoder 12 and encoded according to the contents of the register. For example, if there is no malfunction, use ro OJ, and if there is a paper jam, use ro IJ.
, if it is out of paper, r02J. If the failure requires repair, it is coded as ro 3J. Under the control of the control circuit 31, the coded signal is sent back to the source via the transmission aggregation circuit 13 after a predetermined period of time (for example, 30 seconds) after the start of normal facsimile reception. The control circuit 31 is connected to the encoder 12 during normal facsimile transmission.
Control so that it is not output from.

At the transmission source, it enters the reception separation circuit 21 from the reception line,
The coded signal is sent to decoder 22. It is decoded by the decoder 22 and received by the reception status register 23.
Set each bit of . For example, if the coded signal is "01", a bit corresponding to the state of "paper jam" is set, and if the coded signal is "02", a bit corresponding to the state of "out of paper" is set. The control circuit 31 controls the decoder 22 so that no signal is output during normal facsimile reception. The contents of the reception status register 23 and the transmission number register are sent to the output means 25, and the contents are displayed. For example, the following is displayed on a liquid crystal display. Recipient's phone number r03-123-4567J and "paper jam"
The following message will be displayed. As another example of the output means, it is also possible to record and output the recipient's telephone number and the status of the recipient's equipment on the receiving paper. The transmitting side can know the failure status of the receiving side equipment.

〔Effect of the invention〕

As explained above, the present invention transmits the device status of the receiver by providing a function to return the status of the device and the status of the device failure, such as paper jam in the receiving paper, to the device that sent the message. This can be recognized by the machine and has the effect of avoiding invalid transmission operations.
