Abstract: A cutting insert mounting system adapted for a cutting tool in which, by using a tightening screw, a cutting insert is detachably mounted on an insert mounting seat. A central axis of a screw hole of the insert mounting seat is inclined with respect to a normal direction of a bottom wall surface of the insert mounting seat. When the cutting insert is placed on the insert mounting seat, on a virtual plane defined to expand the bottom wall surface, a central axis of the screw hole is shifted from the central axis of a through hole of the cutting insert to the side of one of two side wall surfaces of the insert mounting seat. On the virtual plane, an axis shift direction of the central axis of the screw hole and an inclination direction of the central axis of the screw hole are different.

Abstract: An information processing unit determines, when receiving information through a reading process from a recording medium, whether a user identified by the information has transition authority for a transition from an energy saving mode to a normal mode of carrying out information processing; sends a transition request for carrying out a transition from the energy saving mode to the normal mode to a power supply control part when determining that the user has the transition authority; and carries out the transition to the normal mode in response to the transition request and, when authentication of the user is successful, displays on a user interface part a display screen page for receiving an operation concerning the information processing.
