A vibration-canceling mechanism includes a vibration transfer member of a plane shape inserted between a vibration-origination system having at least one resonance frequency and an object to which a vibration is applied from the vibration-origination system. The actuator is configured to move the medicament container within the housing when the actuator is moved from a first configuration to a second configuration. By using as a mask a lamination of the electrode layer and gate insulating film and the field insulating film, an ion implantation process is executed to form n+-type source and drain regions. The frictional sheets 210 are disposed to form frictional-sheet groups 211 each including five frictional sheets 210 disposed successively. The flexible shower arm assembly includes an elongated flexible member defining a fluid transfer path, the flexible member having a first end and an opposite second end. The lens memory and the lens controller operate with the first power and the second power, respectively, when the photographing lens is mounted to the camera body.
