原位置检出方法、纸张处理装置及图像形成设备
摘要：
一个在运送纸张的过程中对纸张执行预定处理的处理单元。原位置检出单元通过使用检出单元检出移动构件的一部分而检出移动构件的原位置。原位置检出单元预先设置用于识别原位置的检出范围，当在移动构件处于停止状态下检出用于检出原位置的所述部分时，通过假定检出位置处于所述检出范围内而不需将所述移动构件移动到所述检出范围外从而将所述移动构件的所述部分的检出位置设置为所述原位置。
摘要（英）：

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 homeposition 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.
