〔Effect of the invention〕

As explained above, in the present invention, when a medium is inserted from the first inlet/outlet, the switching valve connects the first conveyance path and the third conveyance path, and the planetary gear meshes with the first driven gear. As a result, the first feed roller and the third feed roller are rotated by one driving source, the medium is smoothly transferred between the first conveyance path and the third conveyance path, and the medium is transferred from the second entrance/exit. is inserted, the switching valve connects the second conveyance path and the third conveyance path, and the planetary gear meshes with the second driven gear, whereby the drive source connects the second feed roller and the third conveyance path.
Since the feed roller rotates, the medium is smoothly transferred between the second conveyance path and the third conveyance path.

Therefore, according to this, it is possible to convey the medium in a short time, and since complicated control is not required and only one drive source is required, it is possible to realize an inexpensive conveying device.

In addition, the present invention also provides the following effects.

While a medium is being conveyed in one of the first and second conveyance paths, even if the medium is inserted into the other conveyance path through the entrance/exit, the power from the drive source is not transmitted to the feed roller of that conveyance path. Therefore, even if the medium comes into contact with the feed roller, the medium will not be transported into the apparatus, and jams can be prevented.

In addition, since the connecting portion of the conveyance path on the side not connected by the switching valve is closed, even if the medium inserted into the other conveyance path is inserted further into the side, the switching valve will cause the medium to be inserted into the third conveyance path. Therefore, the medium may collide with the medium being conveyed, causing a jam, or may interfere with a sensor installed in the conveyance path, causing malfunction, or other adverse effects on the device. You can also get the effect of not having one.

In addition, since the above operation is performed by mechanically linking the switching of the switching valve and the switching of power transmission, there is no need for complex control and this is achieved by a simple method, so there is no malfunction. Moreover, the effect of reducing costs can also be obtained.

In addition, since the power transmission to each feed roller is switched by a planetary gear linked to a switching valve, the feed rollers may become locked due to a jam or the like on the first or second conveyance path, making one conveyance impossible. Also, without complicated control,
It is possible to continue processing using the other conveyance path simply by switching the switching valve, which also provides the effect of high operational efficiency.

Furthermore, by connecting the first conveyance path and the third conveyance path, or the second conveyance path and the third conveyance path with a switching valve, one continuous conveyance path is formed to convey the medium. Therefore, even if the medium is deformed, it will not get mixed into another conveyance path or jam, and it will be possible to smoothly convey the medium in both insertion and ejection directions.

Furthermore, since both the first and second entrances and exits serve as the medium insertion and discharge ports, there is no need to provide a dedicated discharge port, and the device can be made more compact.
