0). With this operation, the control unit 40 starts the drive motor 39 and rotates each transport roller. In the case of this embodiment, step 101 is YES because there are two sheets to be conveyed.

First, a paper sheet 36 having a short dimension (a)
Is inserted into the transport path 43 from the paper sheet insertion section 32 (step 102), the dimension a of the paper sheet 36 becomes
Is shorter than the distance A between the paper rollers 3 and
After the leading end of the paper sheet 36 reaches the carrying roller 19 (the carrying roller 22) (step 103), even when the trailing end of the paper sheet 36 comes off from the carrying roller 20 and the carrying roller 23, the leading end of the paper sheet 36 remains The transport guide 44, the transport roller 25, and the transport roller 28 are not reached (Step 104: N).
The paper sheet 36 falls into the storage box 31 (step 1).
05). Thus, first, the conveyance of the paper sheet 36 having a short size is completed. Here, the sheet to be conveyed again is 1
Step 101 is still Y because there are remaining sheets.

Next, the paper sheet 37 having the long dimension (b)
Is inserted into the conveyance path 43 from the paper sheet insertion section 32 (step 102), the size b of the paper sheet 37 is longer than the distance A between the conveyance roller group 41 and the conveyance roller group 42,
After the leading ends of the rollers reach the transport rollers 19 and 22 (step 103), the transport rollers 20 and 23
Before the trailing edge of the paper sheet 37 comes out of the paper guide 37, the leading end of the paper sheet 37 is
(Step 104: Y), and the paper sheet 37 is stored in the storage B.
The transport roller 25 and the transport roller 2 do not drop to the OX31.
When the trailing end of the sheet 37 comes off from the transport roller 26 and the transport roller 29, the sheet reaches the sheet take-out section 33 (step 106).

Since the conveyance of the paper sheets to be handled is completed by this, there is no paper sheet to be conveyed (step 101:
N), the start / stop switch 34 is turned off (step 1).
07), the rotation of each transport roller is stopped by stopping the drive motor 39, and a series of sheet transport operations is completed.

According to the paper sheet transport apparatus shown in this embodiment, the paper sheet is set on the transport path by setting the distance between the transport rollers in advance in accordance with the size of the paper sheet to be handled. , It is possible to convey the paper sheets 36 with short dimensions to the paper sheet storage box 31 and the paper sheets 37 with long dimensions to the paper sheet take-out section 33, respectively.

In the above-described embodiment of the present invention, a configuration has been described in which paper sheets having a size longer than a predetermined size and paper sheets having a shorter size are separated and conveyed / stored. By providing a plurality of paper sheet sorting configurations as described above, it is also possible to discriminate paper sheets for each finer size. For example, as shown in FIG.
2 and a sheet information reading sensor 38, and a sheet storage BO between a conveyance roller group 41 and a conveyance roller group 42.
When X31 is provided and paper sheets are transported from the left side of the figure,
Unnecessary paper sheets are dropped into the paper sheet storage box 31, only necessary paper sheets are passed through, and the paper sheet information reading sensor 38 reads the paper sheet information. A method of providing a paper sheet sorting structure having a set of transport roller groups provided at different intervals from the transport roller group 41 and the transport roller group 42 on the transport path that allows only the leaves to pass therethrough. A separate transport path is provided in place of the paper sheet storage BOX 31 provided between the transport roller group 42, and the dropped paper sheets are transported to another transport path,
Further, the present invention is also applicable to a method of providing a sheet sorting structure having a set of conveying rollers arranged at intervals different from that described above in another conveying path.

[0020]

According to the present invention, each sheet can be passed only on the conveyance path by setting in advance the distance between the conveyance rollers in consideration of the size of the sheet to be handled. Each type of paper can be transported to a separate location, and special components such as sensors and switching gates, as well as control programs for calculating the dimensions of these paper sheets, are not required, and accurate transport is possible with an inexpensive configuration. .
