By the way, when trying to increase the tray due to the number of pages etc.,
It is known that a plurality of sorters are connected in series so that some sorters in the middle also have a relay function to the next sorter. A relay transport path was installed in the lower stage, and it was moved up and down together with the storage shelf unit. However, in the collating device as described above, since the storage shelf unit is provided with the relay conveyance path, the size of the storage shelf unit is increased and the weight is increased. It was a big obstacle in moving it. Previously, the inventors of the present invention provided a relay conveyance path on a machine frame frame different from the above-mentioned storage shelf unit, and made it continuous by arranging the relay conveyance path to face the discharge port independently of the vertical movement of the storage shelf unit. We proposed a collating device that allows the sheets to move independently in the relay conveyance path only when they are stored in the tray of the sorter (Japanese Utility Model Application No. 62-187484).

[Problems to be solved by the device]

In the collating device, the relay conveyance path is swingably supported by the machine frame frame at a retracted position out of the moving area of the storage frame unit, and its leading end is between the operating position for transporting paper and the retracted position. It is movably supported. Then, the position detection sensors provided at the operating position and the retracted position detect whether the relay conveyance path is at the operating position or the retracted position. Since this relay conveyance path is connected to the drive system, a gear 505 interlocking with the drive means, which is held at a predetermined position near the operating position of the paper conveyance path 501 as shown in FIG. It engages with a gear 503 provided at the tip of the path 501. Conventionally, the position of the conveyance path 501 holding the gear 503 is detected by the sensor 507 to determine whether or not the paper conveyance path 501 is in the operating position. Therefore, the gears 503 and 505 are provided.
It was not possible to detect whether or not there was a positive meshing condition. [Object of the Invention] As shown in FIG. 20, the present invention is a second gear 505 that meshes with a first gear 503 provided in a sheet conveyance path 501.
Is rotatably provided on one end side of the paper transport path 501 at the operating position, and the engagement of the first gear 503 and the second gear 505 is detected by the sensor 507 on the second gear 505 side. A sheet having a simple structure can detect that the sheet conveyance path 501 is in the operating position and that the gears 503 and 505 are in a positive meshing state by detecting the set state of the sheet 501 in the operating position. The purpose is to obtain a carrier.

[Means for Solving the Problems] In order to solve the above-mentioned drawbacks of the conventional example, the paper transporting device of the present invention has a paper receiving port connected to the paper exit of the paper feeding device and a paper from the paper receiving port. A relay transport path for transporting toward the discharge port, a storage shelf unit having a plurality of storage shelves for sequentially collating and storing the paper from the paper receiving port, and a storage rack unit facing each storage shelf to the paper receiving port. And a means for moving the relay conveyance path between a retracted position out of the movement area of the storage rack unit and an operating position facing the discharge port. In the above, when the relay conveyance path is moved to the operating position, the second gear provided on the displacement member that engages with the relay conveyance path and displaces to the predetermined position is displaced by the displacement member to the predetermined position. As a result, Detecting displacement of the displacement member and the displacement member that drive-connects by meshing with the first gear provided in the feeding path and discharges the sheet from the relay conveying path from the sheet discharge port to another sheet handling device It is characterized in that it is provided with a detecting means. Further, a first gear and a driving means for driving the gear are provided in the relay conveyance path, and the driving means is operated when the first gear and the second gear are engaged with each other, and the first gear is operated.
