Reference numeral b denotes a friction plate to be joined to a part of the sheet surface, which is formed in a rectangular shape, and is disposed on each side of the sheet 3. The friction plates 1a and 1b are attached to a drive mechanism 2 that is driven individually. As shown in FIG. 2, the drive mechanism 2 has one end fixed to the outside of the friction plates 1a and 1b and the other end connected to the connecting portion 1a.
It has three movable parts 5 connected to one. The connecting portion 11 is fixed to a case body 2a supported by a frame (not shown) or the like. Further, the material and shape of the movable portion 5 protruding from the case body 2a are determined so as to be swingable along the surface direction of the sheet 3. Further, a driver 8 is attached to each movable portion 5.
A coil 7 for passing a current from the coil 7 is wound, and each of the movable portions 5 is surrounded by magnets 6 having different poles. The part 5 is configured to swing (reciprocate).
The drive mechanism 2 reciprocates at a constant speed when the movable portion 5 reciprocates in the sheet transport direction (right in FIG. 3) by, for example, controlling the energization of the coil 7, When moving backward in the direction opposite to the transport direction (left in FIG. 3), it is configured to move backward at a sharply accelerated speed.
Here, when the friction plates 1a, 1b move to the left sharply, a kinetic frictional force acts between the friction plates 1a, 1b and the paper 3 so that the friction plates 1a, 1b
When a and 1b slide on the surface of the sheet 3 and move to the right at a constant speed, the maximum static frictional force acts and the friction plate 1
The friction coefficients of the friction plates 1a and 1b and the reciprocating speed of the movable portion 5 are determined so that a and 1b shift the paper 3.

３は搬送される。Therefore, according to the paper transporting apparatus of this embodiment, when the driver 8 applies a current to the coil 7 to move the movable portion 5 by the magnetic force between the magnet 6 and the movable member 5, the friction plates 1 a and 1 b As shown in FIG. 4, it reciprocates right and left.
The paper 3 is conveyed along the guide 4 by the movement of the friction plates 1a and 1b.

へ順次送り出されることになる。In this case, when the friction plates 1a, 1b move rightward at a constant speed, the maximum static frictional force acts between the friction plates 1a, 1b and the paper 3, and the friction plates 1a, 1b transport the paper 3. Shift in the direction. On the other hand, when the friction plates 1a and 1b move sharply to the left,
Since a kinetic friction force acts between the sheet 1b and the sheet 3 and the kinetic friction force is smaller than the maximum static friction force, the friction plates 1a and 1b
Slide the surface back. Therefore, the paper 3 is sequentially sent out in the transport direction.
