Patent number: 8773116Abstract: A rotation angle detecting device includes a rotating body rotating according to rotation of a vehicle pedal; a magnet attached to the rotating body; a magnetism detection element disposed facing the magnet at a predetermined interval from the magnet; and a first control circuit connected to the magnetism detection element. The center of the magnet is placed at the rotation center of the rotating body. The magnetism detection element detects magnetism of the magnet to output a detection signal. The first control circuit outputs an angle signal corresponding to a rotation angle of the rotating body according to the detection signal, and outputs a switching signal according to the rotation angle of the rotating body. The rotation angle detecting device reliably detects a rotation angle and turns a stop lamp on and off for example with a simple structure.Type: GrantFiled: August 30, 2011Date of Patent: July 8, 2014Assignee: Panasonic CorporationInventors: Shinji Hirose, Kouji Oike, Kiyotaka Sasanouchi

Patent number: 7321230Abstract: The rotation angle-detecting device has a main rotator and two detecting rotators that rotate as the main rotator rotates. Each of the two detecting rotators has a magnet and a magnetic detector. As the detecting rotator rotates, a change occurs in magnetic lines of force from the magnet. From the change, the magnetic detector detects rotation of the detecting rotator. According to the rotation detected, the device determines the rotation angle of the main rotator. In addition, a ring-shaped ferromagnetic body is disposed around the magnet or the magnetic detector of the detecting rotator. The structure described above enables magnetic detection without disturbance in each magnetic field of the magnets, and even in a downsized structure, the device can detect the rotation angle with high accuracy.Type: GrantFiled: March 5, 2007Date of Patent: January 22, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaharu Ushihara, Kouji Oike
