PURPOSE:To enable a form to be carried in or out while a conveying means such as rotors and the like continues operating to one direction by providing a device with not only a rotor which rotates reversely to the direction that a sheet material is conveyed, in a conveying direction reverse gear section, with but also a pressing means which is composed of an auxiliary body and of a rotor, and is opposite to the above side rotor. CONSTITUTION:A roller 77 which always rotates reversely to the direction that a form is carried in, is provided in a switch back section 21, and a roller 81 is also provided to be opposite to the above said roller. When the form is carried in, the convex side of a cam is engaged with a shaft 75 allowing the roller 81 to be in spaced relation to the roller 77. And when the roller is rotated reversely allowing the form which has been carried in, to be carried out, the concave side of the cam is engaged with the shaft 75 allowing the roller 81 to press the roller 77 through the carried form. So, the form is carried in to a switch back section 21 by means of conveying force of a counterrotation section 19. And the form can be carried out of the switch back section 21 by means of a combination of the roller 77 and the roller 81, each of which rotates to one direction. Accordingly, the form can be conveyed to the reverse direction with no roller 77 normally or reversely rotated allowing the device to be controlled in a simple manner.
