FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to one embodiment of the present invention.

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 a telephone exchange network, switches to a data communication path, and holds a loop. The NCU 2 connects the telephone line 2a to the telephone 4 when the signal level (signal line 20a) from the control circuit 20 is “0”, and connects the telephone line 2a when the signal level is “1”. It is connected to the facsimile machine side.
In a normal state, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, sends the transmission signal from the addition circuit 12 to the telephone line 2a via the NCU 2, and transmits the 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 modem 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27ter, V.I. 29, V.I. 17, V.I.
34, and performs modulation and demodulation based on
Each transmission mode is designated by the signal line 20c. The modulator / demodulator 8 receives a signal output on a signal line 20b, outputs modulated data on a signal line 8a, receives a received signal output on a signal line 6a, and outputs demodulated data on a signal line 8b. Output.

The ANSam sending circuit 10 is a circuit for sending an ANSam signal. When a signal of signal level "1" is output to the signal line 20d, the ANSam sending circuit 10 sends an ANSam signal to the signal line 10a and sends it to the signal line 20d. When the signal of the signal level “0” is being output, no signal is output to the signal line 10a.

The addition circuit 12 inputs 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.
a. The reading circuit 14 reads an image of a document and outputs the read image data to a signal line 14a. The recording circuit 16 is for sequentially recording information output to the signal line 20e line by line.

The memory circuit 18 is used for storing raw information of read data or encoded information, and also for storing received information or decoded information.

The operation unit 22 includes a one-touch dial, abbreviated dial, numeric keys, * / # keys, a start key, a set key, other function keys, and the like, and the pressed key information is output to a signal line 22a.

The double-sided reading selection button 24 is a button for instructing selection of double-sided reading. When the button 24 is pressed, a pressing pulse is generated on the signal line 24a.

A double-sided reading selection lamp 26 is a lamp for indicating that double-sided reading has been selected.
When a clear pulse is generated at f, the light turns off, and thereafter, every time a pressing pulse is generated on the signal line 24a, the sequence of turning on, turning off, and turning on is repeated. The double-sided reading selection lamp 26 outputs a signal having a signal level "1" to the signal line 26a when "lit" and outputs a signal level "1" to the signal line 20a when "off". 0 "is output.

The document length detecting circuit 28 is a circuit for detecting the document length. When a detection start pulse is generated on the signal line 20h, the resolution output on the signal line 20g (8 pel / mm in the main scanning direction in the standard mode). × 3.85 in the sub-scanning direction
line / mm, 8pe in main scanning direction for fine mode
l / mm x 7.7 line / mm in the sub-scanning direction, 8 pel / mm x 15.4 line in super fine mode
/ Mm9), read information to be output to the signal line 14a, and sequentially output the original sub-scanning length to the signal line 28a.

The display circuit 30 is an LCD or the like capable of displaying a message. The display circuit 30 receives information on the signal line 20i and reads, for example, "Since it was a long document, only the front side was read." Please select from only sending, scanning the back side, combining in memory, and interrupting the transmission. "" Long manuscript, cannot automatically scan both sides. " Continue or select to interrupt reading and transmission of original information ".

In the facsimile apparatus of this embodiment, when double-sided reading is selected, the control means 20 reads only the front side when the original length exceeds a predetermined length while reading the front side information. Upon completion, the operation of encoding the read information and storing the read information in the memory circuit 18 is controlled, and after the reading operation of the front side is completed, the fact that only the front side has been read is displayed on the display circuit 30 because the document is a long document. Control to display.

Then, after only the reading of the front side is completed, only the front side is transmitted. The back side is set, the back side is read, and stored in the memory circuit 18, and then transmitted from the first page to the front side and back side in this order. The user is allowed to select each processing mode of interrupting transmission, and control is performed to execute subsequent processing in accordance with the selection. Here, it is assumed that the length of a document determined to be long is different depending on the width of the long document.

FIGS. 2 to 9 are flowcharts showing the control flow of the control circuit 20 in the first embodiment of the present invention.
