An apparatus is disclosed for measuring a three-dimensional shape of a subject, which includes: a turntable unit configured to include a turntable, and a support frame adapted to rotatably support the turntable; a measurement head configured to photograph the subject on the turntable and to measure the three-dimensional shape of the subject based on at least one resultant photograph of the subject; and a transformable holder being attached to the measurement head and holding the turntable unit. The holder is configured to be selectively placed in an unfolded position in which the turntable unit is unfolded with respect to the measurement head, and a folded position in which the turntable unit is folded with respect to the measurement head, as a result of transformation of the holder, and further configured to allow, when in the unfolded position, the subject to be located on the turntable unit and to be photographed.

An image processing device comprises: plane conversion means which receives a subject image in which a subject having a particular shape has been captured and shape information about three-dimensional shape of the subject from the outside and converts the subject image into a plane image in which the subject is viewed from a prescribed direction based on the shape information; and in-plane position detection means which recognizes a subject area in the plane image as an area representing the subject and determines a position of the subject in the plane image.

In an image forming apparatus, an exposure head has blue light emitting elements, a base on which the blue light emitting elements are provided, bonding pads formed on the base, and an aluminum-made reflecting layer formed on each bonding pad. Each aluminum-made reflecting layer has a reflectivity of 90% or higher to blue light from the light emitting element with respect to the regular reflection component. Part of blue light generated by one of the light emitting elements may travel to an adhered surface of the light emitting element, but it is reflected by the aluminum-made reflecting layer without being absorbed by the adjacent bonding pad, so that that part of blue light is re-directed toward a microcapsule recording sheet. This construction considerably increases the power of blue light emitted from each blue light emitting element provided in the exposure head, thereby enabling provision of an image forming apparatus in which the power of light emitted from each blue light emitting element provided in an exposure device is considerably increased.

The housing 2 is integrally formed with a cylindrical support portion 6. A cylindrical bore 30a is formed through the support portion 6. An inner diameter of the bore 30a is made substantially equal to an outer diameter of the semiconductor laser 4. The semiconductor laser 4 is therefore supported in the bore 30a. A lens barrel 7 holds therein a collimator lens 5. The outer diameter of the lens barrel 7 is also substantially equal to the inner diameter of the bore 30a. The lens barrel 7 is also supported in the bore 30a.

An optical scanning system including a light source which emits a light beam; a light deflector having at least one reflecting surface providing a deflecting surface for deflecting the light beam emitted by the light source, in a deflection plane defined by the light beam incident to the light deflector and the light beam deflected by the light deflector; and a light-converging device which receives the light beam deflected by the light deflector and forms an optical image on an object to be scanned, an optical axis of the light-converging device being spaced from, and extending parallel to, the deflection plane.
摘要:
An optical scanning apparatus of the present invention is for optically scanning a medium. In the optical scanning apparatus, a light source receives image information and emits light beam modulated in accordance with the image information. A single optically imaging system is positioned in a single location for receiving the light beam from the light source and for focusing the light beam to be focused on the medium. A reflective mirror formed with a single reflective surface is provided for reflecting the light beam from the optically imaging system to direct the light beam to the medium. The reflective mirror is rotated by a motor at a fixed speed to allow the reflective surface to scan the light beam on the medium in a scanning sweep. Surfaces other than the reflective surface of the reflective mirror is prevented from directing the light beam to be focused on the medium.
