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 uses cartridges with tools mounted thereon to press works W, and has a change position where the cartridges are changed. A cartridge transferring and loading device is provided which draws out the cartridges from the change position via a linear path L and transfers and loads the cartridges in a cartridge magazine located on an extension of the linear path L. The transferring and loading device has a cartridge moving-in and -out mechanism that moves both forward and backward to transfer and load the cartridges both in the punch press and in the magazine
