A stage apparatus includes a stationary support plate; a Y-direction moving member including a Y-direction rod portion and an X-direction rod portion connected thereto parallel with the stationary support plate, the Y-direction moving member being supported by the stationary support plate so as to relatively move in the Y-direction; an X-direction moving member supported by the X-direction rod portion so as to relatively move in the X-direction. One of the X-direction moving member and the stationary support plate is provided with a projection, and the other of the X-direction moving member and the stationary support plate is provided with a rotation restriction support portion supporting the projection to move in a plane parallel with the stationary support plate relative to the other of the X-direction moving member and the stationary support plate and which prevents rotation of the X-direction moving member about the X-direction rod portion.

A stage apparatus includes a stationary support base-plate; a Y-direction moving member supported on the stationary support base-plate to move in a Y-direction; and an X-direction moving member supported on the Y-direction moving member to move in an X-direction orthogonal to the Y-direction. The Y-direction moving member includes a Y-direction rod portion which extends in the Y-direction and an X-direction rod portion connected to the Y-direction rod portion and extends in the X-direction. The stationary support base-plate includes a Y-direction guide device for guiding the Y-direction rod portion of the Y-direction moving member so as to slide in the Y-direction, and a Y-direction support device for supporting a free end of the X-direction rod portion so as to allow movement of the X-direction rod portion in the Y-direction. The X-direction moving member is supported by the Y-direction moving member so as to slide in the X-direction.

A one-way rotational transfer mechanism includes a rotary input shaft; a hollow-cylindrical rotary output shaft positioned around the rotary input shaft; a circumferentially-uneven-width-space forming portion formed on the rotary input shaft to form at least one accommodation space between the rotary input shaft and the cylindrical inner peripheral surface; a movable member; balls positioned between first and second holding surfaces; at least one roller member installed in the accommodation space; and a biasing device which biases the movable member so that the balls are sandwiched between the first and second holding surfaces and so that an normal surface and the roller member come into pressing contact with each other. The circumferentially-uneven-width-space forming portion is shaped so that a rotation of the rotary input shaft is transferred to the hollow-cylindrical rotary output shaft via the roller member when the rotary input shaft is rotated.

A fluorescent structure is provided on a curved recess plane of a reflector. The fluorescent structure has a shape of a cylinder which is cut by a plane including its central axis and along its longitudinal direction. An inner wall of the fluorescent structure tapers in like a cone from both ends to the central portion of the fluorescent structure. The structure includes a fluorescent material, for example YAG, which converts blue light to white light and diffuses the white light. Blue LEDs are provided close to both ends of the structure. The blue LEDs are positioned such that blue light emitted from the blue LED enters from both ends and is led to the central portion.

An image-capturing device includes a photographing lens, a first imaging device, a second imaging device and a diaphragm. The photographing lens forms subject images on the first and second imaging devices. The first imaging device receives light rays of the infrared spectrum through the photographing lens and captures a subject image formed by the infrared rays. The second imaging device receives light rays of the visible spectrum through the photographing lens and captures a subject image formed by the visible rays. The diaphragm is mounted in a photographing optical system which includes the photographing lens, and the diaphragm forms a first area and a second area. The first area transmits light rays of the infrared and visible spectrums. The second area selectively transmits light rays of either the infrared or the visible spectrum.

A stage apparatus includes a stationary support plate; a Y-direction moving member including a Y-direction rod portion and an X-direction rod portion connected thereto parallel with the stationary support plate, the Y-direction moving member being supported by the stationary support plate so as to relatively move in the Y-direction; an X-direction moving member supported by the I-direction rod portion so as to relatively move in the X-direction. One of the X-direction moving member and the stationary support plate is provided with a projection, and the other of the X-direction moving member and the stationary support plate is provided with a rotation restriction support portion supporting the projection to move in a plane parallel with the stationary support plate relative to the other of the X-direction moving member and the stationary support plate and which prevents rotation of the X-direction moving member about the X-direction rod portion.

A drive mechanism for a camera includes a movable member located behind a photographing lens and linearly moved along an optical axis thereof, the movable member supporting an image pickup device; an AF coil secured to the movable member or an immovable member of the camera; a magnetic force generating device which is secured to the other of the movable member and the immovable member, so as to linearly move the movable member in the optical axis direction relative to the immovable member by applying a magnetic field upon the AF coil; and a controller which controls the direction of electric current flowing in the AF coil so that image light transmitted through the photographing lens is converged onto an image pickup surface of the image pickup device. The AF coil is a planar coil which is wound on a plane parallel with the optical axis.

A digital camera having a camera-shake compensation mechanism and a luminance compensation processor is provided. The camera-shake compensation mechanism compensates for a camera-shake by adjusting a relative relation between positions of an optical axis of a photographing optical system and a center of an image of an imaging device. The luminance compensation processor compensates for luminance information of pixels of the imaging device, which are outside an image circle of the photographing optical system during a camera-shake compensation operation performed by the camera-shake compensation mechanism.

An anti-shake apparatus of a photographing apparatus comprises a movable unit and a fixed unit. The movable unit has an imaging device and can be moved and rotated on a plane which is perpendicular to an optical axis of a camera lens of the photographing apparatus. The fixed unit supports the movable unit in a movable and rotatable situation on the plane. The movable unit and the fixed unit have a position-detecting apparatus that detects first position-information of the movable unit in a first direction being perpendicular to the optical axis. The is fixed unit has an optical sensor unit that has two position-detecting elements which are used for detecting the first position-information as the position-detecting apparatus. The movable unit has a slit light-source unit that has two slit light-sources which are used for detecting the first position-information as the position-detecting apparatus.
