Abstract: A discharge roller device includes at least one roller pair, at least one first free roller and at least one second free roller. The roller pair includes a driving roller and a pressure roller pushed against the driving roller. The first free roller is disposed at a side where the driving roller is disposed with respect to a plane including a nip part of the roller pair and a part of the first free roller is located in the pressure roller side rather than the plane. The second free roller is disposed at a side where the pressure roller is disposed with respect to the plane and a part of the second free roller is located in the driving roller side rather than the plane.

Abstract: The present invention provides a press with an automatic tool changing function which can reduce the amount of time required to change cartridges. A punch press 1 uses cartridges 2 with tools mounted thereon to press works W, and has a change position 7 where the cartridges 2 are changed. A cartridge transferring and loading device 5 is provided which draws out the cartridges 2 from the change position 7 via a linear path L and transfers and loads the cartridges in a cartridge magazine 3 located on an extension of the linear path L. The transferring and loading device 5 has a cartridge moving-in and -out mechanism 19 that moves both forward and backward to transfer and load the cartridges 2 both in the punch press 1 and in the magazine 3.
