いう欠点かある。The conventional facsimile machine described above sends information on the selected linear density to the other party's device at the beginning of communication, and then transmits the read image signal with the linear density fixed. If the transmission time is increased, fine letters become unclear, and if the line density is reduced, the transmission time becomes longer.

受信記録部8に出力する。The communication control unit 6 modulates and outputs the image signal output from the image signal processing unit 5 to which line density information according to the control signal 4a from the marker detection unit 4 is added to the facsimile receiving side via the line 7. At the time of reception, the received image signal is demodulated from the line 7 and output to the reception recording section 8.
受信記録部8は、通信制御部6からの画信号に付加され

A thin portion 2a and a coarse portion 2b of the calligraphy drawn in are determined, and a marker 3a and a marker 3b are set at the beginning in the sub-scanning direction 1b. When communication starts, the reading unit 1 performs sub-scanning 1.
It moves in the direction of the arrow b and reads the marker 3a (a marker with fine writing in the main scanning direction) and outputs an image signal 1a. The marker detection unit 4 identifies the signal of the marker 3a included in the image signal 1a using a preset reference value and outputs a control signal 4a instructing reading at a thin line density.

て主走査と副走査の速度を制御し受信記録をする。The reading unit 1 lowers the main scanning and sub-scanning speeds according to the thin line density instruction of the input control signal 4a, and reads 2a of the original 2.
When the marker 3I] (a thick mark in the main scanning direction) is read, a control system that instructs reading with a coarse line density from the marker detection unit 4 (the main scanning and sub-scanning speeds are increased by the wholesale signal 4a) is read. The image signal 1a obtained by reading the portion 2b of the original 2 is output.The communication control section 6 adds information indicating fine and coarse line densities from the marker detection section 4 to the image signal and transmits it to the line 7. The reception recording unit 8 controls the main scanning and sub-scanning speeds in accordance with information indicating the fine and coarse line densities detected from the image signal received from the line 7 and performs reception recording.
