摘要： A flash lighting apparatus effects proper lighting for different portions of an object field by the use of a light control device disposed on an optical path between a flash light emitter and the object field. In one embodiment, the flash light control device has a plurality of main control portions and at least one sub-control portion adjacent to main control portions. An adjusting circuit adjusts the quantity of light projected by the control portions so that the quantity of light projected by a sub-control portion may be between the quantities of light projected by the adjacent main control portions. In one embodiment, a single booster circuit provides boosted voltage for use in a light emission control circuit that causes flash light emission and also for use in a control circuit for a light control device. In one embodiment, a photometering circuit photometers areas of an object field, and the number of light control portions is greater than the number of photometered areas.

摘要： A vibrational actuator includes an oscillator that generates vibrational energy; a mover that is rotationally driven around a first axis by the vibrational energy; an output shaft that rotates around a second axis by using a rotational force communicated from the mover; and a flange portion projecting out from the output shaft along a direction intersecting the second axis, that rotates together with the output shaft. Pressure is applied to the mover at a position between the flange portion and the oscillator. A distance from the first axis to an outer portion of the mover over an area where the mover is pressed against the flange portion is set to a value large enough to prevent the first axis and the second axis from becoming tilted relative to each other.

摘要： A vibration motor including a vibration element having a driving force output member, which is excited to produce a combination of different vibrations and to generate an elliptical vibration in the driving force output member. A relative moving member in pressure contact with the driving force output member is driven by the elliptical vibration to move in relative motion with respect to the vibration element. A pressure support member is fixed between the vibration element and a first base member, to place the vibration element in pressure contact with the relative moving member. A second base member supports the relative moving member. A vibration absorbing member absorbs vibration produced by the elliptical vibration generated by the vibration element in at least one of the relative moving member and the pressure support member. The vibration absorbing member may be located between the first base member and the pressure support member, between the pressure support member and the vibration element, and between the relative moving member and the second base member.
