PURPOSE:To perform an accurate positioning, by constituting a device such that, after a forward end of a intermittent feed paper is grasped at a given position, the center thereof is pushed upward to bend it in a ?-shape, and the rear end is restrained, the grasping of the forward end and the push-up of the center are released, and the forward end is brought into contact with a stopper through elasticity of the paper. CONSTITUTION:A forward end of a flexible sheet S, fed intermittently, is held at a given position by a holding means 3, and with a push-up tool 4 turned, the center of the sheet S is then pushed upward to bend the sheet S in a ?-shape. Then, with a restraint means 5 turned, the rear end of the sheet S is restrained. If holding of the holding means 3 and push-up of the push-up tool 4 are released, the forward end of the sheet S is pushed forward under the own weight of the sheet S and through elasticity of the sheet S itself to make contact with a stopper 6, the forward ends are trued up at a given position, and the sheets S are positioned in an accurate location. This constitution causes the sheets to be reliably positioned, and enables to save a laber and automate a device. |
