摘要： The present invention provides a light guide, a line-illuminating device, and an image-scanning device that provide excellent uniformity in the amount of light produced. A light-reflecting portion comprised of spherical concave surfaces becomes a reflecting surface having spherical convex surfaces when it is seen from the inside of the light guide. Even when the incident angle of light from the light source unit is slightly offset, the reflection angle in spherical convex surfaces significantly changes, and light is reflected uniformly toward the upper surface serving as a light-emitting surface. In particular, when the fine spherical concave portions of the light-reflecting portion have a small depth, the incident light from the end surface is reflected toward the upper surface, serving as a light-emitting surface, and both side surfaces without reflecting back to the light-emitting unit side, so that uniform reflection can be achieved.

摘要： A light guide, a line-illuminating device, and an image-scanning device are provided which are excellent in uniformity of the light amount. A light-reflecting portion comprised of tubular concave surfaces becomes a reflecting surface having tubular convex surfaces when seen from the inside of the light guide. With such structure, even when the incident angle of light from a light source unit slightly displaces, the reflection angle in the tubular convex surfaces significantly changes. In an irregular surface having a triangular shape, as in a conventional example, the incident angle becomes almost uniform in the area far from the light source unit, and thereby the reflection angle also becomes uniform. Consequently, it is difficult to achieve uniform reflection in the main-scanning direction. However, with the tubular concave surfaces, light is reflected uniformly toward the upper surface as a light-emitting surface.

摘要： An optical disc drive includes: an optical head with an actuator and a photodetector; a tracking driver outputting a drive signal to the actuator; a first tracking error signal generator for generating a first tracking error signal based on an output signal of the photodetector; first and second lens position control sections for respectively outputting first and second lens position control signals to the tracking driver; and a selector for selectively supplying the first tracking error signal to the first or second lens position control section according to a moving velocity of the optical head during a seek operation. The first lens position control signal is obtained by extracting signal components, of which the frequencies are equal to or lower than a predetermined frequency, from the first tracking error signal. The second lens position control signal is obtained by extracting DC components of the first tracking error signal at on-track points thereof.

摘要： A lens array 4 is formed as an erect 1:1 imaging lens by superimposing two lens plates 40 and 40 together. Each lens plate 40 consists of a number of micro lenses 41 which are regularly provided at a predetermined pitch and in a two-dimensional manner. This lens plate 40 is for example made by press molding the ultraviolet curing resin in a soft condition using a transparent mold and by irradiating the ultraviolet light on the ultraviolet curing resin from outside for hardening. Since the lens array 4 is provided with micro lenses 41 in rows in a sub-scanning direction, deterioration of an amount of light level resulting from the displacement between a light axis of the lens and an image sensor 6 is not generated.
