As a result, the endless conveyor belt 74 of the vertical conveyor table 51 moves, and the postal matter M is carried out to the corresponding conveyor table 2i. Then, as described above, the corresponding horizontal transport table 2 is displaced to the inclined position Ps, and the postal matter M is put into the target sorting box 6. If the postal matter M is loaded after the horizontal transport table 2 is displaced to the inclined position Ps, the horizontal transport table 2 is again moved to the horizontal position Ph.
However, a plurality of mail items M ... May be continuously discharged from the same horizontal transport table 2. In this case, the control for the horizontal transport table 2 is performed as follows. First,
When the next command is given in a state where the horizontal transport table 2 is stopped at the tilt position Ps, the horizontal transport table 2 is stopped at the tilt position Ps as it is. Further, when the horizontal conveyance table 2 is in the process of returning from the inclined position Ps to the horizontal position Ph and the next command is given before reaching the preset position, the horizontal conveyance table 2 is returned to the inclined position Ps from the middle. . Further, if the next instruction is given after the preset position is passed while the horizontal transport table 2 is returning from the inclined position Ps to the horizontal position Ph, the horizontal transport table 2 is temporarily returned to the horizontal position Ph. After that, it is displaced to the inclined position Ps. As a result, the continuous mail items M can be reliably put into the target sorting box 6 and the stable operation of the horizontal transport table 2 is ensured.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, the detection unit is exemplified by a sensor that is pressed when a paper sheet passes and detects the paper sheet, but this does not prevent the use of other sensors such as an optical sensor. In addition, the detection unit provided on the horizontal transport table two before the designated horizontal transport table was used to displace the designated horizontal transport table to the inclined position. The designated horizontal transport table may be displaced to the inclined position by the detection unit provided on the transport table. Further, although the mail sorting device is exemplified, it can be used as a paper sorting device for sorting arbitrary paper sheets. In addition, the detailed configuration, shape, quantity, method, and the like can be arbitrarily changed without departing from the scope of the present invention.
