摘要： A stringed instrument includes a body, a string, a string exciting device and a bridge. The body supports the string, the string exciting device and the bridge. The string has a scale length determined by a distance between a first support point and a second support point. The string exciting device is designed to be driven by an electrical signal having a certain frequency and vibrate the string by applying an excitation signal having a frequency corresponding to the frequency of the electrical signal. The bridge has the first support point and a surface located between the first support point and the second support point and designed to come into contact with the string during vibration of the string.

摘要： A taking lens system is provided with, from the side of the object to be photographed, a first lens unit (G1) having positive optical power, a second lens unit (G2) having negative optical power, a third lens unit (G3) having positive optical power and a fourth lens unit (G4) having positive optical power. Zooming is performed by moving the first to fourth lens units (G1) to (G4), and focusing is performed by moving the fourth lens unit (G4). When the distance from the most object-to-be-photographed side surface (r1) of the first lens unit (G1) to the imaging surface at the wide angle end is TLw, the overall focal length of the taking lens system at the telephoto end is ft, the overall focal length of the taking lens system at the wide angle end is fw, and the focal length of the first lens unit (G5) is fl, relationships 0.5≦TLw/ft≦1.0 and 6.0≦fl/fw≦20.0 are satisfied.

摘要： The present invention provides a variable magnification optical system for forming an optical image of an object on the light-receiving surface of an image sensor with a variable magnification. The variable magnification optical system includes an optical construction comprising, from an object side, a first reflective surface, a first movable unit, a second reflective surface, and a second movable unit. The optical axis is bent at substantially ninety degrees by the first reflective surface and is further bent by the second reflective surface, and, during magnification variation from the wide-angle end to the telephoto end, the first and second reflective surfaces are kept in fixed positions with respect to the image surface, and the first and second movable units move along the optical axis. The variable magnification optical system fulfills a prescribed conditional formula.

摘要： An imging lens device has a zoom lens system and an imaging sensor. The zoom lens system has a plurality of lens units and changes gaps between the lens units to thereby generate an optical image of an object which can be optically and successively zoomed in and out. The imaging sensor which converts an optical image generated by the zoom lens system into an electric signal. The zoom lens system comprises, from the object side, a first unit having a negative power, a second unit having a positive power, the second unit having a cemented lens element joining three lens elements, and a lens element having a positive power, a third unit having a positive power, and an aperture stop disposed between the first unit and the second unit. Among the three lens elements which form the cemented lens element, a lens element disposed on the object side directs a convex surface toward the object side while a lens elements disposed on the image side directs a concave surface toward the image side. The zoom lens system is fulfilled the predetermined conditions.
