Abstract

PURPOSE:To prevent a useless call and to improve the using efficiency of facsimile equipment by adding an interruption processing function and an auxiliary storage device to the facsimile equipment. CONSTITUTION:When a connection request from the other facsimile equipment is executed in the middle of transmitting/receiving a facsimile picture, a control part 13 executes an interruption processing temporarily and, thereafter, stores the connection information of the facsimile equipment, to which the connection request is execute, into an auxiliary storage device 12. The picture-transmitting/ receiving processing to be temporarily held is resumed, and after the picture- transmitting/receiving is completed, a communication with the opponent facsimile equipment is activated based on the connection information. Thus, even when the facsimile equipment executes the connection request in the middle of the picture-transmitting/receiving, a connection can be surely executed without executing the retrial of the connection.

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 can perform efficient retries when the other party's facsimile machine is in use.

[Conventional technology]

When a conventional facsimile machine sends an image to the other party's facsimile machine, for example, as shown in FIG.
is currently transmitting images to facsimile device 2,
Assume that facsimile device 3 makes a connection request to facsimile device 1 . In this case, it will be busy,
The facsimile machine 3 retries the connection several times every time a certain period of time elapses.

[Problem to be solved by the invention]

The conventional facsimile machine described above stays busy for a long time when the other party's facsimile machine is sending or receiving a large amount of information, but attempts to reconnect regardless of the state of the other party's facsimile machine. Because there are
The drawback is that retrying the connection several times will result in failure, resulting in a failure to send data.

[Means to solve the problem]

When there is a connection request from another facsimile device while transmitting or receiving a facsimile image, the facsimile device according to the present invention temporarily performs interrupt processing and then information about the connection of the facsimile device that received the connection request. remember,
- The temporarily suspended image sending/receiving process is restarted, and after the image sending/receiving process is completed, communication with the other party's facsimile device is started based on the connection information.

[Effect]

According to the present invention, even if the other party's facsimile device makes a connection request during image transmission/reception, connection can be reliably established without retrying the connection.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention. In the figure, 4 is a transmitting/receiving switching unit that performs switching when sending and receiving facsimile images, 5 is a transmitting unit that sends image data to the other party's facsimile machine through a line when sending images, and 6 is a receiving unit that performs switching when sending and receiving facsimile images. T is a receiving unit that receives image data from the other party's facsimile machine through a line, T is a document to be sent, 8 is an image reading unit that reads this sending document 7 and converts it into an electrical signal, and 9 is a received image. , 10 is an image output unit that restores image data based on electrical signals sent from the other party's facsimile machine into a visible image, and 11 is an image output unit that temporarily stores the image as an electrical signal and also sends commands to/from the other party's facsimile machine. A storage device 12 stores all image information converted into electrical signals to be sent to the other party's facsimile machine when the other party's facsimile machine is in use. When there is a connection request from a facsimile device other than the other party, the connection information of the facsimile device that received the connection request, such as a magnetic disk device that stores the telephone number, two separate image numbers for sending and receiving images, etc. The auxiliary storage device 12 is the transmitter 5. Receiving section 62 Image reading section 82 Image output section 10. Storage device 11
and a control unit that monitors the operation of the auxiliary storage device 12 and controls it to operate correctly.

Next, the operation of the facsimile machine having the above configuration will be explained with reference to FIG. First, facsimile machine 1
is currently transmitting an image to facsimile machine 2, and when a connection request is received from facsimile machine 3, the communication with facsimile machine 2 that is currently being executed is temporarily suspended, and the temporary communication with facsimile machine 3 is suspended. Start communication. During this communication, the facsimile device 3 does not receive all the image information, but only the minimum information necessary for recalling, that is, the telephone number of the other party's facsimile machine, and whether the image is being sent or received. 1 image number is received and stored in the auxiliary storage device 12. After the facsimile machine 1 completes communication of the minimum necessary information with the facsimile machine 3, the facsimile machine 1
Resume communication with. On the other hand, when temporarily communicating with the 7mm 7mm device 1, the facsimile device 3 sends the above-mentioned minimum amount of information, and at the same time sends all the information to be sent that has been read through the phone number 9 and the image reading unit 8 of the other party's facsimile device 1. The image information is stored together in the auxiliary storage device 12 in preparation for later retransmission. When the facsimile device 1 finishes communicating with the facsimile device 2, it stores it in the auxiliary storage device 12, calls the facsimile device 3 based on the information about the communication with the facsimile device 3, and transmits the image specified by the image number. command to do so. The facsimile machine R3 receives the command, extracts image information from the auxiliary storage device 12, and sends it to the facsimile machine 1. When the transmission is completed, the facsimile devices 1 and 3 delete the related information from the auxiliary storage device 12 and terminate the connection.

〔Effect of the invention〕

As described in detail above, according to the facsimile device according to the present invention, by providing the facsimile device with an interrupt processing function and an auxiliary storage device, connection requests from other facsimile devices can be received while sending or receiving facsimile images. , the current sending/receiving image processing is temporarily put on hold, and the connection information of the facsimile device that made the connection request, such as the telephone number and two separate image numbers for sending/receiving, is stored in the auxiliary storage device. Then, the temporarily suspended image sending/receiving process is resumed, and after the image sending/receiving process is finished, the called party resumes the connection using the connection information stored in the auxiliary storage device, thereby eliminating unnecessary calls. This has the effect of preventing the facsimile machine from being occupied by the facsimile machine and increasing the efficiency of use of the facsimile machine.
