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 with improved countermeasures against unreceivable reception.

(Prior Art) Conventionally, in a facsimile machine, the facsimile machine on the sending side reads and encodes the information on the set document, and then transmits it through a telephone line, and the facsimile machine on the receiving side reads the information that has been sent. Information is transmitted by restoring the information and recording it on recording paper.

In a facsimile machine having a self-diagnosis function on the receiving side, when receiving, the status of the plotter section and the functions of each part of the device such as paper jams are checked to determine whether reception is possible. This self-diagnosis function is intended to improve the reliability of facsimile machines.

(Problem to be Solved by the Invention) However, in such conventional facsimile machines, if reception is not possible during reception, the ringing remains without changing to reception mode, so the line is disconnected on the sending side. Since the line is not closed and communication is not possible, this line will be disconnected. At this time, the operator on the sending side cannot know the reason why communication is not possible, so the sending operation is repeated many times to the receiving side when trying to communicate, which is a burden for the operator on the sending side. become.

Further, when the unreceivable state is restored, the recipient is not notified of the restoration, so the sending facsimile machine cannot determine the timing for re-transmission, which hinders efficient use of the facsimile machine.

(Purpose of the Invention) Therefore, the present invention provides that, when reception is not possible at the time of reception, an unreceivable message is sent to the other party who has made a communication request, and a sendable message is sent when the unreceivable state is restored. By sending a message, the transmitting operator is clearly notified of the unreceivable status and that the unreceivable status has been restored, reducing the burden on the transmitting operator and improving the efficiency of using the transmitting facsimile machine. The purpose is to

(Structure of the Invention) In order to achieve the above object, the invention according to claim 1 provides an automatic transmission and reception function and a self-diagnosis function that checks the functions of each part of the device and determines whether or not reception is possible. If a facsimile machine with a Further, the invention according to claim 2 is characterized in that, when the unreceivable state is restored, a transmittable message is transmitted to the destination to which the unreceivable message was sent.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 7 are diagrams showing an embodiment of the invention according to claims 1 and 2. FIG.

In FIG. 1, reference numeral 1 denotes a facsimile device, and the facsimile device 1 includes a main body 1a including a document table 2, an operation section 3, and the like.

The manuscript table 2 is a stand for placing manuscripts (not shown) to be transmitted, and can collect and send a plurality of manuscripts. The operation unit 3 includes, for example, a start key, a numeric key, a copy key, a mode changeover switch (normal mode, absent mode), various control switches, a display unit, etc., and is used to control each part of the facsimile machine 1. Input the command signal.

As shown in FIG.
6, a communication section 17, a control section 18, and an operation section 3.

The scanner unit 11 is equipped with a line image sensor and a document conveying means (not shown), and while conveying the document set on the document table 2 one by one by the document conveying means, the line image sensor reads the image information of the document. Each line is read, photoelectrically converted, and output to the control unit 18.

The memory 13 stores the image information digitized by the A/D converter in the control unit 18 in a predetermined line (for example, 1 line).
The data is stored at each time and sent to the Korg decoder section 14.

The Korg decoder unit 14 aims to shorten the transmission time and improve efficiency of image information, and compresses (encodes) the image information with the image information when transmitting, and converts the compressed (encoded) image information into the original when receiving. Play information.

The character generator section 15 converts the message information (unreceivable messages, sendable messages, etc.) encoded and stored in the ROM in the control section 18 into character patterns to the communication section 1.
Output to 7.

If the original size of the facsimile machine of the recipient is different, the image scaling unit 16 reduces or enlarges the image at a predetermined magnification and transmits the image to the communication unit 17 in order to adjust the original size.
or send the received image to the plotter section 12.

The control unit 18 includes a CPU, ROM, RAM, etc.
It executes the sequence of the facsimile machine 1 according to the program stored in the ROM, and also checks the functions of each part in the facsimile machine 1 using a self-diagnosis function, thereby executing the process of transmitting a message when reception is not possible according to the present invention. Note that the message to be transmitted is stored in advance in a predetermined area in the ROM as code information.

The recording section 12 includes a thermal head (not shown), a conveyance means, an ink sheet, a recording paper, etc.
An image is recorded on the recording paper based on the image information and control signal input from 3.

The communication unit 17 includes a modulation/demodulation unit, a network control unit, etc. The modulation/demodulation unit is generally referred to as a modem, and transmits the image information of the original compressed by the KOG decoder unit 14 to an external line. At the same time, the modulated signal input from the external line is demodulated to extract the digital signal. The network control unit is generally referred to as an AA-NCU, and has an automatic transmission/reception function that automatically calls a destination and automatically receives a call in response to a transmission from an external line.

Next, the effect will be explained.

The present invention is characterized by processing when the self-diagnosis function of the facsimile machine 1 causes the facsimile machine 1 to become unable to receive data. This process will be explained below based on the flowchart shown in FIG.

It is checked whether or not there is an incoming call from the external line by the facsimile machine (step PL). If there is an incoming call, the self-diagnosis function of the control section 18 determines whether or not it can be received (step pg). The receivable state can be determined by, for example, detecting the state of the plotter unit 12, and if the plotter unit 12 is a thermal type, the temperature of the heater of the thermal head, or if the plotter unit 12 is an electrostatic laser type, the temperature of the heater for constant toner wear is detected. A temperature sensor detects whether a predetermined temperature has been reached, and a paper jam sensor detects a paper jam in the recording paper transport section. When reception is possible, perform reception processing (step P,)
, when reception is not possible, CED, C3I and Di are sent from facsimile machine 1 as shown in the signal sequence shown in FIG.
s to the calling party in order to confirm that the line is connected, confirm that facsimile machine 1 is the called terminal, and confirm that facsimile machine l has the CCITT standard receiving function. do. That is, even if the facsimile machine l is in the reception disabled state, the facsimile device l temporarily enters the reception state, and the calling party transmits the DC3 and TSI signals.

Transmission by the calling side and reception by the called side are determined by the DC3 signal and the TSI signal. Then, the facsimile machine 1 checks whether reception of the TSI signal is completed or not (step P4), and repeats this check until the reception is completed.

When the reception of the TSI signal is completed, check whether the subscriber number indicated by the TSI signal is being received for the first time or not (step P, ); if it is the -th time, flag FL1 is set to request the transmission of an unreceivable message. Set (ON) (
At step P6), the telephone number of the other party is stored in a predetermined area of the memory section 13, and then a DCN signal is output to cut off communication (step P7). - Immediately cut off communication if it is not the first time. Here, the telephone number of the calling party based on the TSI signal is temporarily stored in the RAM in the control unit 18.

Thereafter, the process returns to checking for an incoming call (step p+).

On the other hand, when there is no incoming call (step p+), the above flag F
Step P to check whether LI is ON or not.
8) When FLl is ON, a call is made to the party to whom the communication request was made using the telephone number stored in the RAM in the control unit 18 (for example, this call is made approximately 20 seconds after the communication is disconnected). ) (step P,). Then, the message to be sent is divided depending on whether alternative reception is possible with a device other than facsimile 1 and when it is not possible (Step Pro
) If alternative reception is possible, send the "unreceivable molecule alternative receiver number" shown in FIG. 5 (step P11), and if alternative reception is not possible, send the "unreceivable message" shown in FIG. 6.
(Step P1z).

Note that the causes of failure mentioned in these unreceivable messages are set in advance according to the location of the failure. After sending the message, turn off the transmission request flag FLI
Step P1), the "unreceivable message" sent flag FL2 is set (ON) (step P14). Then, it transmits a DCN signal to cut off communication (step P
1. ) to check the incoming call (step p+). This "unreceivable message" allows the calling side operator to know the status of the receiving side. Here, to explain how to send the "unreceivable message", in the facsimile machine 1,
After entering the transmission mode, the code information of the "unreceivable message" stored in the ROM of the control section 18 is developed into bit images by the character generator section 15 and sequentially transmitted. At this time, if the memory section 13 has a large capacity, it is possible to develop one page's worth of code information into a bit image at a time. In addition, if the memory unit 13 has a small capacity, bit images are developed in block units (several lines - 10-odd lines) at a time, and after transmitting one block's worth of bit images, the bit image of the next block is developed. , sent. The following steps are repeated in sequence. A "sendable message" to be described later is similarly expanded into a bit image and transmitted.

After that, check whether the "unreceivable message" has been sent and the unreceivable state has been restored, step P, b),
If the transmission has been completed and the transmission has been restored, the facsimile device 1 calls the destination again (step P2). Then, a "sendable message" as shown in FIG. 7 is sent, and the sent flag FL2 is turned off (step P1.).

After that, a DCN signal is sent and communication is cut off (step P
2°), and return to checking the incoming call (step P,). As a result, even if the facsimile machine l serving as a receiving terminal is unable to receive data due to a malfunction in the plotter section 12, etc., the line is closed at one end, the telephone number of the other party is memorized, and then the call is made again. In addition, if alternative reception is possible at this time, the alternative reception number is also notified at the same time, so unnecessary retransmission operations on the sending facsimile machine can be omitted. can. Furthermore, when the facsimile machine 1 recovers from the unreceivable state, by transmitting a ready-to-send message to the destination, the facsimile machine on the sending side can perform efficient transmission. Therefore, unnecessary operations on the transmitting operator can be reduced and the burden on the transmitting operator can be significantly reduced.

(Effects) According to the inventions described in claims 1 and 2, if reception is not possible at the time of reception, a reception-unavailable message is sent to the other party who has made a communication request, and when the reception-unavailability state is restored. , since a transmittable message is transmitted, the burden on the operator on the transmitting side can be significantly reduced, and the efficiency of use of the facsimile machine on the transmitting side can be improved.
