Since a large number of classes 3 can be transported at a short pitch P, it is not necessary to lengthen the transport path, and the size of the apparatus can be reduced.
Furthermore, since a large number of paper sheets 3 can be conveyed at a short pitch, the processing capacity can be improved. This makes it possible to transport the paper sheets 3 at a low speed,
It is also possible to suppress the generation of noise due to the transport motor and the like. In addition, as shown in FIG. 23, when the paper sheets 3 are accumulated from the short side direction by the so-called impeller 30, the paper sheets 3
24, it is possible to install a large number of impellers 30 in accordance with the width in the short direction of the sheet, so that the size of the apparatus can be reduced as compared with the case where the paper sheets 3 are stacked from the longitudinal direction as shown in FIG. Can be.

It comprises two outlet sensors 14 for detecting that the transport posture of the leaves 3 has been changed by approximately 90 ° along the transport surface.

Here, the structure of the rotating shaft 41 will be described in detail. As shown in FIGS. 3 and 4, the rotating shaft portion 41 includes a pair of a guide shaft 45 and a driving shaft 42 that are disposed so that their distal ends face each other through an opening 22 formed in the guide 5. A motor 40 for rotatingly driving the drive shaft 42 (in a counterclockwise direction in FIG. 2) via a belt 44, a drive pulley 43, and the like, and a solenoid 46 for moving a guide shaft 45 forward and backward with respect to the tip of the drive shaft 42. , A wear member 420 and a sliding member 421 provided at the tip of the drive shaft 42 or the tip of the guide shaft 45, respectively. The corners of the tip portions of the wear member 420 and the sliding member 421 that face each other are chamfered for guiding the conveyed paper sheets.

The wear member 420 includes the wear member 4.
In a state where the sheet 20 is rotating and the sheet 3 is sandwiched between the sheet 3 and the sliding member 421, the material, the surface roughness, and the like are set so that slip does not occur between the sheet 3 and the lower surface. Has been taken into account. On the other hand, when the wear member 420 is rotating and the paper sheet 3 is sandwiched between the wear member 420 and the wear member 420, the sliding member 421

When the sliding member 421 separates from the wear member 420 due to the rise of the sheet, the rotation of the paper sheet 3 stops, and the paper sheet 3 delivered to the short transport path 12 is further downstream (in the transport direction F side). Transported to

As a result, as shown in FIG. 10, the transport direction changing unit 8 rotates along the transport surface while sandwiching the paper sheet 3 between the drive shaft 42 and the guide shaft 45 constituting the rotary shaft unit 41. While rotating the paper sheet 3 by 90 ° in the direction L, that is, while changing the transport direction (transportation posture) of the paper sheet 3 from the longitudinal direction to the lateral direction, the paper sheet 3 is moved from the longitudinal transport path 11 to the short side.

For example, as shown in FIG. 11 and FIG. By delaying the timing for holding the leaves 3 by the displacement K, the delivery position to the short conveyance path 12 can be moved by a distance (movement M) according to the displacement K. Accordingly, for example, even when sheets of different sizes are successively conveyed, by adjusting the timing for pinching the sheets 3 without changing the position of the short conveyance path 12 or the like. The transport posture of each sheet can be changed.

In portions where the detection accuracy is relatively unimportant and the sheets need to be simply transported over a long distance or where the sheets are stacked, the sheets can be transported in the short direction. Therefore, at the portion where the paper sheets are transported in the longitudinal direction, the occurrence of skew is suppressed, and
Since the sheets can be detected over a long distance, the detection accuracy can be improved. Also, in the portion where the paper sheets are transported in the short direction, a large number of paper sheets can be transported at a short pitch, so that the paper sheets can be transported at a low speed and the like, and the noise of the transport motor and the like can be reduced. be able to. further,
According to the first, second, eighth, or ninth aspect of the present invention, the transport direction of the paper sheet (transport posture of the paper sheet) is changed by rotating the paper sheet. The transport direction can be changed, and the size of the apparatus can be reduced.

According to the third, fourth, tenth, or eleventh aspect of the present invention, the transport direction of the paper sheet is changed by revolving the paper sheet. In addition, the delivery position of the paper sheet before and after the change of the transport direction of the paper sheet can be selected widely, and the degree of freedom in designing the apparatus can be improved.

Further, in the invention according to claim 5, 6, 12 or 13, the conveying direction of the paper sheet is changed by rotating and revolving the paper sheet. In addition to the effects of the invention, it is also possible to arrange the transport paths in which paper sheets are transferred in directions orthogonal to each other, and to improve the degree of design freedom of the apparatus. .

According to the second, sixth, ninth or thirteenth aspect of the present invention, one of the pair of nipping members is transported. By rotating the paper sheet along the surface, the conveyance posture of the paper sheet can be changed, so that the apparatus can be configured with a simple structure and the size of the apparatus can be reduced.
