Abstract: A light quantity adjustment apparatus includes a pair of substrates having a light-path aperture; a plurality of diaphragm blades disposed between the pair of substrates; a driving ring that opens and closes the plurality of diaphragm blades; and a driving device. The plurality of diaphragm blades is supported by the substrate via a first guide plate made of a resin film. The substrate and the first guide plate are provided with guide grooves fitted into protrusions formed in the plurality of diaphragm blades to guide the blades. Guide grooves of the substrate are formed of concave grooves. Guide grooves of the first guide plate are formed of through holes. The through holes of the first guide plate have a narrower width than the concave grooves of the substrate to engage in the protrusions of the diaphragm blades and to guide the diaphragm blades in the open and close direction.

Abstract: A light quantity adjusting device prevents possible violent vibration resulting from an external force. The light quantity adjusting device includes a substrate having an optical path aperture, a blade movably placed on the substrate to restrict the quantity of light passing through the optical path aperture, and an electromagnetic driving device for drivingly opening and closing the blade. The electromagnetic driving device includes a rotating shaft, an arm integrated with the rotating shaft, and a transmission pin provided on the arm. The blade has a cam groove formed therein and engaging the transmission pin. The cam groove includes a continuous groove having a driving area that crosses a pivoting direction of the transmission pin at a predetermined angle to displace the blade and a non-driving area that crosses the pivoting direction of the transmission pin at a substantially right angle to reduce displacement applied to the blade.

Abstract: A camera has a lens portion and an imaging portion arranged on a rotating stand of a pan/tilt apparatus. The pan/tit apparatus includes a device frame; a rotating stand; a regulating device for defining two end positions of an operational range of the rotating stand, and a drive device for driving the rotating stand. The drive device has a rotor and a stator. The rotor has a permanent magnet and an output shaft for engaging an arm portion of the rotating stand. The stator includes an excitation coil for applying a rotational force to the permanent magnet when an electrical current flows in the excitation coil. An electric control device controls the electrical current.

Abstract: This invention provides an automatic framing camera that identifies a still subject, frames it, and photographs it. The ranging direction of a ranging unit (light emitting element and light receiving element) that can range in one direction is changed by a pan motor and a tilt motor, and a still person is searched for by changes in the signal from the ranging unit. Then, the photography direction of the imaging element is turned by the tilt motor toward the center of the face of the person that was found, this is framed with the center of the person's face in the center of the angle of view, and the person's face is photographed by the imagining component.

Abstract: A method and device for simple and sure connection of a filament-shaped connecting body, comprising forwardly feeding a collecting body of a multiplicity of filament-shaped connecting bodies L comprising a filament part f, a head h and a joining part k into a join groove 6b and a head groove 6a, which are provided on a side of a body 2, from rearwardly of the body 2, receiving the head h into a head support part 4d of a head conveying arm 4, causing the head h to approach a tip end of a hollow needle 5 along a predetermined path from a position spaced from the hollow needle 5, simultaneously causing a rod 10 of a piston 9 to force the joining part k into the hollow needle 5 to fit the same into a latch hole b of the head h to connect the filament part f in a ring-shaped configuration.

Abstract: Reflected image light obtained by illuminating a reading portion to be read on a given objective image plane is sent to an image sensor located on the rear side through a reflecting member disposed substantially just above the reading portion. By forming a viewing path inclined forward against, or forward with respect to a vertical plane, the image sensor so as to permit the reading portion to be observed easily, the desired image light reflected from the reading portion is little interfered with by external light entering inside the scanner through the viewing path, thereby to enjoy image processing of high quality.
