Title: Positional sensor
Inventor: TOKUO SEIICHI
IPC: G01D5/245
Filed: 1991-12-24
Abstract: PURPOSE:To eliminate temperature-induced changes or the like in the detection position of a magnet by using the output of a magnetic sensor as its origin at the point when the magnetic field of a detected magnet and a bias magnetic field cancel each other and the intensity of the magnetic field is balanced and turned to zero. CONSTITUTION:A reverse direction bias magnet 3 is provided on the rear side of a magnetic sensor 1. When a detected magnet 2 is not available, a bias magnetic field which is applied to the magnetic sensor turns the output voltage of the magnetic sensor to negative. When the detected magnet 2 is available, the magnetic field of the detected magnet 2 cancels the bias magnetic field and turns the magnetic field to zero. This point is defined as the origin of the output of the magnetic sensor 1. This construction makes it possible to eliminate the changes in the detection point induced by temperature or the like and hence detect the position of the magnet with accuracy irrespective of the temperature factor or the like.

IPC: G03G15/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a sheet feeder whereby a sheet of different size, even when it is mixed to be loaded, can be surely fed. SOLUTION: In the case of loading a sheet mixed in different size, a mixed loading mode switch is operated by a user. Then, a controller is actuated by a mixed loading mode.
