Abstract

PURPOSE:To simplify the equipment constitution and to reduce the cost by recording a reception signal on a line and sending a reproduction signal recorded at the transfer to a facsimile equipment to the line as it is. CONSTITUTION:When the receiving operation is finished or a reception data exists already and its designated transfer time is reached, a main control section 6 starts a transmission control section 3 and a facsimile equipment at a designated transfer destination is called via a network control section 2 to send/receive a prescribed control signal. The main control section 6 reproduces an image data stored in a designated area of a storage section 5 via a storage control section 54 in the transmission step of the image data. The reproduction signal converted by a D/A converter 53 passes through a switching gate 55 and the reproduction signal is sent to a line 1 via the network control section 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a facsimile relay broadcasting device that stores information sent from one facsimile device and transfers it to another facsimile device.

Conventional technology The conventional basic configuration of facsimile relay broadcasting equipment is
As shown in the figure. This device includes a network control unit 12 that controls connection of a transmission line 11, a modem 13 (modulator/demodulator) that demodulates received signals and modulates transmitted signals, and a transmission control unit 14 that executes predetermined transmission control procedures. , M of the received signal
An MF detection circuit 15 that detects the F}-y signal, a main control unit l6 that controls the entire apparatus, a console l7 that is operated by the operator to input various data such as various commands and destinations, and an image of the original. an image reader 18 that photoelectrically reads the image data, an encoder 19 that compresses and encodes the image data read by the image reader l8, a decoder that decodes the compressed and encoded image data, and a paper sheet that receives the decoded image data. The image printer 21 is equipped with an image printer 21 that prints images, and a large-capacity storage section n that can store a considerable amount of image data.

The signal received by the network control unit 12 is supplied to the modem 13, the transmission control unit 14, and the MF detection circuit 15, and the image data demodulated by the modem 13 is stored in the storage unit n, and the signal is sent to the MF detection circuit 15 button and transmitted. The transfer destination information detected by the control unit l4 is associated with the stored image data. When transmitting this stored image data to the transfer destination, the transmission control unit 14 button and the network control unit 12 control the line connection with the other party, and then the image data is reproduced from the storage unit n, and The signal is modulated by the modem 13 and sent from the network control section 12 to the line 11.

Problems to be Solved by the Invention Conventional relay broadcasting devices have had the problem of being complex and expensive. In contrast to the conventional configuration shown in FIG. 2, if it is a dedicated device for relay broadcasting, the image reader 8 and image printer 21 are unnecessary and can be eliminated, and accordingly, the encoder 19 and decoder addition can also be eliminated. You can also do that. However, even in that case, the received image data to be relayed is demodulated by the modem 13 and then stored in the storage section 13, and at the time of transfer, it is taken out from the storage section 13 and sent to the modem 13.
The modem 13 is essential because the signal is modulated and transmitted.

Therefore, there is a limit to the simplification of the structure.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a facsimile relay broadcasting apparatus having a simple configuration.

Means for Solving the Problem Therefore, in the present invention, the received signal on the line is stored in the 11 storage means without being expanded, and the reproduced signal of the storage means is sent to the line when transferred to another facsimile machine. It was configured to do this.

Function: In the structure of the present invention, the received signal on the line is stored as is without being expanded, and the reproduced signal is sent directly to the line during transfer.

Embodiment FIG. 1 shows a schematic structure of a facsimile relay broadcasting apparatus according to an embodiment of the present invention. This device includes a network control unit 2 that controls the connection of a transmission line 1, a transmission control unit 3 that executes a predetermined transmission control procedure (modem training control on the other party), and detects an MF}-in signal of a received signal. MF detection circuit 4 that controls the MF detection circuit 4, a main control unit 6 that controls the entire device, a console 7 that is operated by the operator to input various data such as various commands and destinations, and a main controller that records and reproduces the received signal on the line 1. The storage unit 5 includes a storage unit 5 with a capacity.

The storage unit 5 records the analog transmission signal on the line 1 and sends the reproduced analog transmission signal to the line 1. A digital audio tape recorder (DAT) is suitable for the storage section 5, but other storage devices such as a general cassette tape recorder, floppy disk device, or hard disk device can also be used. The storage unit 5 in the illustrated embodiment includes an A/D converter 51, a digital memory 52, and a D/A converter 5.
3, a storage control section 54, and a gate 55 for switching input/output for recording and reproduction.

The operation of the facsimile relay broadcasting apparatus configured as described above will be described below.

When the relay broadcasting device is called from a certain facsimile device, the transmission control section 3 sends a predetermined control signal via the network control section 2, and then the modulated image data is transmitted from the other party. come.

The transmission control section 3 and the main control section 6 give an operation command signal to the storage control section 54 before proceeding to the step of receiving the image data, and at the same time start the recording operation of the storage section 5, switch the gate of the switching gate 55. Set the switch on the A/D converter 51 side. Therefore, the image data sent from the other party is recorded in the storage section 5 with only one modulated signal on one line 1. Among them, the signals sent from the other party before the transmission control procedure include information specifying the transfer destination and information specifying the transfer time. 4, and the control information is associated with image data stored in the storage section 5 in the main control section 6.

Next, the transfer operation will be explained. When the receiving operation is completed, or when received data already exists and the designated transfer time has arrived, the main control section 6 starts the transmission control section 3. Then, the transmission control section 3 calls the specified transfer destination facsimile device via the network control section 2, and when the line is connected, sends a predetermined control signal. Then, when it comes to the step of transmitting image data, the main control section 6
4 and reproduces the image data stored in the designated area of the storage section 5. The playback signal converted by the D/A converter 53 passes through the switching gate 55 (at this time, the switching gate 55 is controlled by the storage controller 54 to
(set on the A converter side). This playback signal (
The modulated 11 image data) are sent to the line 1 via the network control section 2.

Effects of the Invention As explained in detail above, in the facsimile relay broadcasting device according to the present invention, the received signal on the line is recorded in the storage means without being demodulated, so that it can be sent to another facsimile.
) Since the playback signal of the storage means is sent as is to the housing line when transferred to the device, there is a means for decompressing the signal on the line to obtain image data, and a means for compressing the image data at the time of transfer. is not necessary, which simplifies the device structure and reduces the cost.
