Publication number: 20060226716Abstract: A step motor includes a rotor having four magnetic poles, a first magnetic pole magnetically excited by a first coil, a second magnetic pole magnetically excited by a second coil, and a third magnetic pole magnetically excited by the first coil and the second coil. A gap between the third magnetic pole and the rotor is smaller than that between the first magnetic pole and the rotor and that between the second magnetic pole and the rotor. In the step motor, it is possible to intensify the influence, on the rotor having four poles, of the magnetic fields created from three magnetic poles. Accordingly, this can weaken the magnetic fields set up from the first magnetic pole and the second magnetic pole, which tend to intensify the influence on the rotor, enabling the torque smaller at the time of the rotation start of the rotor.Type: ApplicationFiled: March 22, 2006Publication date: October 12, 2006Applicant: Seiko Precision Inc.Inventors: Hisashi Kawamoto, Seiichi Oishi

Patent number: 7104708Abstract: A sector drive unit for a camera includes sectors capable of opening and closing an aperture provided on a base plate. A first actuator drives the sectors to open and close the aperture, and a drive force transmitting mechanism transmits a driving force of the first actuator to the sectors. A sector retaining unit retains the sectors at the aperture-opening position or at the aperture-closing position, and a second actuator drives the sector retaining unit to a position to retain the sectors and to a position not to retain the sectors. The sector retaining unit prevents the sectors from moving accidentally due to an impact or the like when the sectors are at either the opened position or the closed position. The use of the second actuator for driving the sector retaining unit reduces power consumption and prevents generation of noise during the time of an exposure.Type: GrantFiled: April 14, 2004Date of Patent: September 12, 2006Assignee: SEIKO Precision Inc.Inventors: Yoichi Nakano, Hiroshi Takahashi
