、切換爪８で１外に排出される。The first example of a typical #l configuration of a conventional copier capable of double-sided copying is shown below.
As shown in the figure. The original placed on the contact glass 2 provided on the top surface of the copying machine housing l is exposed to the photosensitive drum 4 by the exposure system 3, and is formed on the photosensitive main drum 4 by a predetermined 9-photography process. The resulting toner image is transferred to a transfer sheet fed from the paper feed section 5, and fixed by the fixing device 6, completing one-sided copying. The transfer paper on which one-sided copying has been completed passes through a three-roller type reversing device 7, and then is transferred to a double-sided copying machine.
When the mode is selected, the original is introduced into the reversing guide 9 by the switching claw 8, and is ejected onto the intermediate tray 11 by the reversing feed roller 10 and stacked. When a predetermined number of sheets have been stacked, the original is placed on the contact glass 2. When the paper in the intermediate tray is replaced or turned over and the copy button is pressed, the paper in the intermediate tray is fed to the transfer section of the photosensitive drum 4, and after the toner image on one side is transferred and fixed, the paper is switched after the reversing device 7. It is ejected out of the machine by the claw 8, and a double-sided copy is obtained. When the single-sided copy mode is selected, the switching pawl 8 is used to eject the paper to the outside after the single-sided copy is completed.

トレイは両面複写モードでのみ使用され、片面モードで
は使用されず遊んでいるので使用効率が悪い。In conventional copying machines capable of double-sided copying, as described above, the intermediate tray is used only in the double-sided copying mode, and is not used in the single-sided mode and is idle, resulting in poor usage efficiency.

以下、本発明の実施列１図面に基いて詳細に説明する。In order to achieve the above-mentioned object, the present invention enables transfer paper to be set from the outside on the intermediate tray of a copying machine capable of double-sided copying, and the paper feed selection means selects the transfer paper set on the intermediate tray. The selection and features of the present invention will be described in detail below with reference to the drawings of the first embodiment of the present invention.

る。In the copying machine according to the present invention, stacks of paper of various sizes can be set on the intermediate tray from the outside. When the front surface Ae of the copying machine housing is opened, the intermediate tray can be easily reached, and a guide and a paper size detection means that can be displaced according to the paper size are provided on the intermediate tray.
このようにしたことにより、中間トレイは両面複写２行

紙台が２つから３つに増加したことになる。By doing this, the intermediate tray can also be used as a normal paper feed tray when double-sided copying is not being performed.For example, in the example shown in FIG. Including the first paper feed tray 54a1 and the second paper feed tray sb), the number of paper feed trays has increased from two to three.
各給紙台にセットされた用紙の選択は、操作部の給紙選
択キーにより行なわれ、表示部に表示される。The paper set on each paper feed table is selected using a paper feed selection key on the operation section, and is displayed on the display section.

If the optional tray 12 having the optional cassette 2a and the optional cassette B12bi can be installed, the display will be as shown in FIG.
When the optional tray is not connected, the selection and paper size of the first paper feed tray, second paper feed tray, and intermediate tray are shown in order from the top. When the optional tray is connected, the first paper feed tray is shown in order from the top. Paper stand, option cassette A1 option cassette B selection? It is better to do as shown.
