Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はファクシミリ送信装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a facsimile transmission device.
従来のファクシミリ送信装置では、変調器を２つもち送
信データを振り分けて２つの変調器に入力し総合として
の通信時間を短縮するものはなかった。No conventional facsimile transmitter has two modulators, and transmit data is distributed and input to the two modulators to shorten the overall communication time.
上述した従来のファクシミリ送信装置は、変調器が１つ
の構成となっており、伝送路の特性によって変調器の上
限の変調速度が決定されるため、伝送時間を短縮するに
は限界があるという欠点が存在する。たとえばＣＣＩＴ
Ｔ、Ｖ２９の規格によれば、９６００ｂｐｓが最高の伝
送速度である。The above-mentioned conventional facsimile transmission device has a single modulator, and the upper limit modulation speed of the modulator is determined by the characteristics of the transmission path, so there is a drawback in that there is a limit to shortening the transmission time. exists. For example, CCIT
According to the T and V29 standards, the maximum transmission speed is 9600 bps.
本発明の目的は、同じ特性の伝送路を用いた場合、伝送
速度が従来比で１／２となるファクシミリ送信装置を提
供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile transmitting apparatus whose transmission speed is 1/2 that of the conventional apparatus when a transmission line with the same characteristics is used.

している。The facsimile transmission device of the present invention includes a control section having a function of dividing the lines of a read document into two lines for each line, a buffer memory for storing at least one line of data from the control section, and the memory. It has two modulators for receiving data from the transmitter, modulating it, and transmitting it to the transmission line.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例のブロック図である。FIG. 1 is a block diagram of one embodiment of the present invention.

５へ交互に送られる。In FIG. 1, a reading unit 1 reads one line of a document. The read data is sent to the encoder 2. The data encoded by the encoding unit is changed to 1 by the switching unit 3.
Each line is sent alternately to buffer memory 4 or buffer memory 5.
例えば１ライン目がバッファ・メモリ４へ送られたなら

ッファ・メモリ５へ送るための切替スイッチは、ファク
シミリ装置の制御部（図示せず）によって制御される。For example, if the first line is sent to buffer memory 4, the second line is sent to buffer memory 5, and the third line is sent to buffer memory 4. After that, repeat this alternately. A changeover switch for alternately sending data to buffer memory 4 or buffer memory 5 is controlled by a control section (not shown) of the facsimile machine.
バッファ・メモリへのデータの転送は、バッファ・メモ
リがいっばいでないことを確認して行なわれる。Transfer of data to the buffer memory is performed after confirming that the buffer memory is not full.
バッファ・メモリ４又は５から変調部６又は変調部７へ
のデータの転送は、変調部６又は変調部７の要求に応じ
て行なわれる。変調部６及び変調部７では引取ったデー
タを変調して、伝送路Ａ及び伝送路Ｂへと送出する。Data is transferred from the buffer memory 4 or 5 to the modulation section 6 or 7 in response to a request from the modulation section 6 or 7. The modulating section 6 and the modulating section 7 modulate the received data and send it to the transmission path A and the transmission path B.

時間を半分にできる効果がある。As explained above, the present invention includes a control unit that has a function of dividing each line of a read document into two,
a buffer memory for storing at least one line of data from the control section; and a modulator for taking data from the buffer memory, modulating it, and sending it out to a transmission path.
By sending signals through two transmission lines, the transmission time can be halved.
