本発明は、二つの印字部を有するプリンタ、ファクシミ
リ、複写機、特に用紙の両面印字機構方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printers, facsimile machines, and copying machines having two printing units, and particularly to a double-sided paper printing mechanism system.
従来のプリンタにおいては、両面印字機構は一つの印字

構等必要であった。また先に印字した印字面と同じ機構
部を使用するため、裏面に印字する間、新しい用紙を供
給できず、実質印字速度が上げられない。In conventional printers, the duplex printing mechanism has only one printing section, so after printing on one side of the paper, a mechanism is required to return the paper to the paper feed slot of the printing section again, or a mechanism to turn the paper side to the other side. Met. Furthermore, since the same mechanism as that used for the previously printed printing surface is used, new paper cannot be supplied while printing is being performed on the back side, and the printing speed cannot be increased in practice.

。そのため、裏面−ページ分の画像メモリーを必要とし
、また、データを反転してやる必要が生じ、複雑なデー
タ処理が必要であった。In the case of the above-mentioned conventional double-sided printing mechanism, since one printing section is commonly used for double-sided printing, it has a mechanism for reversing the printed paper to the opposite side. The biggest drawback is that the printing start position does not match the front side and the back side (second printing side), so it was necessary to print on the back side from the bottom side with respect to the front side. Therefore, an image memory for the back side page was required, and the data had to be inverted, requiring complicated data processing.
また一つの印字部を共用しているため、印字スピードが

[Double-sided printing printer system] characterized in that the printing direction is reversed.
次に、本発明の一実施例を示した図面を参照して、本発
明の詳細な説明する。Next, the present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

。Referring to FIG. 1, one embodiment of the present invention includes a printing mechanism section 1 that can print on the front side of paper, a printing mechanism section 2 that can print on the back side of paper, and printing! A paper guide section 3 that guides the paper with prints on its surface from the horizontal section 1 to the printing mechanism section 2, a big roller 6 that supplies the paper, a timing roller 8 that synchronizes the timing of printing start, a laser optical unit 9, and a developing device. vessel 1] and transfer charge-12
, a photosensitive drum 3 , and a fixing roller 14 .
定着された用紙は用紙ガイド部３へ導かれ、用紙案内板

方向７と反対になっている。The fixed paper is guided to the paper guide section 3 and supplied to the printing mechanism section 2 via the paper guide plate 15 and the paper feed roller 16. In this embodiment, the pickup roller 6 of the printing mechanism section 2 is not used and the light is guided directly to the timing roller 18. The printing process of the printing mechanism section 2 is the same as that of the printing mechanism section 1, but as shown in the paper running direction 18, it is opposite to the paper running direction 7.
以上説明したように、本発明によれば、連続的に用紙を
供給することができ、実質の印字速度は用紙の片面印字
の場合と同じ性能を得ることができる。As described above, according to the present invention, paper can be continuously fed, and the actual printing speed can be the same as that of single-sided printing of paper.
また、二つの印字機構部は用紙走行方向が反対であるだ
けで、同じ機構部を用いるので、原価を低減できる。In addition, since the two printing mechanisms use the same mechanism except that the paper running directions are opposite, the cost can be reduced.
