Description of the Related Art Conventionally, in an automatic double-sided copying machine or the like, a double-sided copy is obtained by reversing a single-sided copied sheet and sending it again to an image transfer unit, and further copying the back side of the sheet. Such an automatic double-sided copying machine is disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 60-101551, and the paper transport path switching device used in this copying machine temporarily converts a single-sided copied paper. It uses an intermediate tray for storing paper and an inverter for reversing single-sided copied paper, and therefore has a large height and width, so that it is not suitable for a small space design. Further, in the paper transport path switching device described in Japanese Utility Model Application No. 62-105311, a discharge gate and a switching gate are used for a discharge tray and a return path, respectively, so that the manufacturing cost of the device increases, and However, there is a problem that the drive control of these gates becomes complicated.

に大きくする必要があった。In FIG. 5, reference numeral 1 denotes a first paper transport path, on which a single-sided copied paper is fed in the direction of the arrow from the right, and a flexible paper guide attached to the upper end of the switching gate 4. The sheet passes through the space between 42 and the guide plate to reach the second paper transport path 2 and is sent to a paper discharge device connected to the second paper transport path. When a two-sided copy is desired, the sheet is reversely fed by the forward / reverse roller of the sheet discharging device, the sheet is guided from the second sheet conveying path 2 to the third sheet conveying path 3, and is again conveyed to the transfer section of the copying machine to be transferred to the back side. Copying is performed on the (non-copying side) to obtain a double-sided copy. Here, the switching gate 4 is supported by a rotating shaft 5 and is rotated around the rotating shaft 5 by, for example, a solenoid (not shown). When the switching gate 4 is rotated about the rotation axis to the position as shown in FIG. 6, the single-sided copied sheet sent from the right through the first sheet transport path 1 is the sixth sheet. The sheet is fed in the direction of the arrow in the drawing, passes through the third sheet transport path 3, is returned to the transfer section of the copying machine, and is copied on the copied surface of the sheet to obtain a multiplex copy. This switching gate 4 is the seventh
Conventionally, about eight pieces are conventionally attached to the rotating shaft 5 at regular intervals in parallel with each other. The projecting guide portion 41 below the switching gate moves left or right in the third paper transport path when the paper transport direction is switched, so that the space of the third paper transport path near the junction is particularly large. Needed.

る。The paper transport path switching device according to the present invention will now be described in detail. First, the case of duplex copying will be described. The paper transport path switching device of the present invention shown in FIG. 1 has first and second substantially horizontal paper transport paths and a substantially vertical third paper transport path communicating with each other at a junction of a three-way junction. . A plurality of switching gates 4 fixed to a rotating shaft 5
Does not have a downwardly protruding guide portion of the switching gate existing in the third paper transport path 3 in the conventional paper transport path switching device, but in the first and second paper transport paths at the junction of the three-way junction, respectively. It has a protruding guide extending in the opposite horizontal direction. Then, instead of eliminating the downwardly protruding guide portion of the switching gate, one end thereof is rotatably supported by the rotating shaft 5 at the junction of the three-way junction, and the other end thereof is suspended downward in the third paper transport path. One or more auxiliary gates 6 are provided (see FIG. 4). A flexible paper guide, for example, a mylar film (trade name) 42 is attached to the leading end of the switching gate 4 on the paper discharge path side, and the paper is passed only between the guide plate and the flexible paper guide in the paper discharge direction. Can pass through. The paper conveyance process will be described with reference to FIG. 8. The paper on which the toner image on the photosensitive drum 7 has been transferred by the fixing device 8 to which the single-sided copy has been performed is the first paper.
The sheet is guided to the sheet transport path 1, reaches the sheet discharge device 9 via the second sheet transport path 2 by the switching gate 4, and is reversely fed near the intermediate point between the forward / reverse rotation rollers 91 and 92. At this time, the switching gate 4 is located at the dotted line position in FIG. 3 (the same position as in FIG. 1), and the sheet to be reversely fed is
Although the paper advances toward the paper transport path 3, the leading edge of the paper rotates the auxiliary gate 6, which is rotatably supported around the rotation axis 5, about the rotation axis 5, so that the second and third papers are rotated.
The sheet transport path is opened, the sheet is guided into the third sheet transport path, returned to the transfer section of the copying machine again via the intermediate tray 10, and copied on the back surface of the sheet, thereby obtaining a double-sided copy.

る。Next, the case of superimposed copying will be described with reference to FIG. 2. When the single-sided copied paper is guided to the first paper transport path 1, the switching gate 4 is at the dotted line position and the paper is transported in the direction of the arrow. Then, the leading edge of the sheet rotates the auxiliary gate 6 around the rotation shaft 5, and the first and third sheet conveying paths are opened. Therefore, the paper is transferred to the third paper transport path 3
, Again reaches the transfer section of the copying machine, and the next image (eg, cyan image) is superimposed and copied on the previously copied image (eg, yellow image), and this superimposed copy is repeated a required number of times. Thereby, for example, a color copy is obtained.

の小型化および簡素化を達成することができる。According to the paper transport path switching device of the present invention, the space of the path connecting portion at the junction of the first, second and third paper transport paths can be reduced, and the auxiliary gate can be rotated about the rotary shaft. The drooping makes it easy to drive the switching gate. In addition, the gate is not rotated during single-sided copying, which is usually most frequently used, and the paper transport direction can be changed without rotating the gate even during double-sided copying. Since the conversion can be performed, the load on the electric components used in the device can be reduced, so that the power consumption of the device can be reduced and the device can be reduced in size and simplified.
