DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus such as a facsimile apparatus capable of color reading and capable of both-side transmission.

[0002]

2. Description of the Related Art In a conventional color readable facsimile apparatus, an operator on a transmitter side selects whether or not to perform color reading, and based on the selection state,
It is determined whether color reading or monochrome reading of single-sided document information is performed and executed.

Here, when a facsimile apparatus capable of color reading is used, and a double-sided original is transmitted, the double-sided original is read in front and back in page order. It is possible. For example, for the double-sided document from P1 (page 1) to P10, the front and back sides are read in black and white binary,
For both-sided originals 1 to P15, color reading can be performed on both front and back sides.

[0004]

However, in the above-mentioned conventional example, for example, when an image is sent, the front side is a color original, and the back side is a black and white binary description about the color image information. All of the two-sided information must be transmitted as color reading, and there is a problem that the transmission time becomes longer.

An object of the present invention is to provide an image communication apparatus capable of reading a two-sided original having a color photograph and having an explanation written in characters on the back side in an appropriate color or monochrome binary and transmitting the image. It is intended for.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided an image communication apparatus capable of reading, transmitting, and recording a double-sided original, selecting a reading unit for reading color information and selecting whether to read the surface of the double-sided original in color.

An NCU (network control unit) 2 connects to a terminal of the line in order to use the telephone network for data communication and the like.
It controls connection of the telephone exchange network, switches to a data communication path, and holds a loop. The NCU 2 connects the telephone line 2a to the telephone (CML off) or connects the telephone line 2a to the facsimile machine (CML on) under the control of the bus 26. In a normal state, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates a transmission system signal and a reception system signal, sends a transmission signal from the addition circuit 12 to the telephone line 2a via the NCU 2, and transmits a signal from the other party via the NCU 2. The signal is received and sent to the modem 8 via the signal line 6a.

The modulator / demodulator 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27ter, V.I. 29, V.I. 17, V.I.
This is a modulator / demodulator that performs modulation and demodulation based on the signal 34, and each transmission mode is designated by control of the bus 26. The modulator / demodulator 8 inputs a transmission signal from the bus 26, outputs modulated data to the signal line 8a, inputs a received signal output to the signal line 6a, and outputs demodulated data to the bus 26.

The calling circuit 10 inputs telephone number information in response to a signal from the bus 26, and sends DTMF to the signal line 10a.
Is output.

The addition circuit 12 receives the information of the signal line 8a and the information of the signal line 10a, and adds the result of the addition to the signal line 12a.

Next, two-sided transmission will be described.

There are two communication modes for duplex transmission, an alternate mode and a continuous mode. Here, the alternate mode is a mode in which a double-sided document is transmitted in the order of pages from the front side to the back side. The continuous mode is a mode in which the front side of a two-sided original is all transmitted in the page order, and then the back side of the two-sided original is all transmitted in the page order.
