  • Home-position detecting method, sheet processing device, and image forming apparatus
    Patent number: 8191885
    Abstract: A processing unit performs a predetermined processing on a sheet in a process of carrying the sheet. A home-position detecting unit detects a home position of a moving member of the processing unit by detecting a part of the moving member using a detecting unit. The home-position detecting unit sets in advance a detection range for recognizing the home position, and when a part to detect the home position is detected in a state in which the moving member is stopped, sets a detection position as the home position by assuming that the detection position is in the detection range without moving the moving member once out of a detection range of the detecting unit.
