摘要： The present invention provides an object-sensing device capable of estimating the presence of an object attached on a sensing surface, the kind of the object and the state of the object. An image is formed by a lens with light via the sensing surface, and the light is received by a light-receiving element portion in which a plurality of micro-light-receiving elements are arranged. In the object detection mode, totally reflected light from the sensing surface is received by the light-receiving element portion. The components are arranged at an angle that allows total reflection when there is no object, and does not allow the total reflection condition to be satisfied when there is an object. In the light scattering object detection mode, scattered light from the sensing surface is received by the light-receiving element portion. A signal pattern is obtained by joining detection signal levels of the micro-light-receiving elements in accordance with the arrangement of the micro-light-receiving elements. An increase portion or a drop portion of the signal pattern that appears in accordance with the presence of the object or a difference in the state thereof is analyzed, so that the kind and the state of the object such as a rain drop, muddy water, fogging, ice or the like are estimated.

摘要： There are provided a light emitting unit in which temperature increase due to heat generated in a light emitting element is suppressed to enhance light emission efficiency, a linear illumination device in which the light emitting unit is incorporated, and a contact-type image sensor and an image scanner in which the linear illumination device is incorporated. A lead frame 23 in the light emitting unit has an extension 29. The extension 29 is folded along a case 12, and a plate-shaped heat dissipater 30 is connected to the extension 29. The connection is carried out by forming holes 29a and 30a in the extension 29 and the heat dissipater 30, respectively, and engaging a protrusion 31 formed on the case 12 in the holes 29a and 30a. The extension 29 thus comes into tight contact with the heat dissipater 30 and is fixed thereto. The heat dissipater 30 is made of a good thermally conductive material, such as copper, and formed separately from the lead frame 23.

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.

摘要： A line-illuminating device is provided in an image-scanning device such that the end of a transparent light guide is not disengaged from a casing and uniformity of the light amount can be achieved. A rib is formed unitarily with a resin mold which constructs a light source unit so as to cover an end of a light-emitting plane of the transparent light guide. The end of the light guide can be prevented from being disengaged from the casing by the rib. Another rib is formed unitarily with the end of the casing on the opposite side of the light source unit. This rib covers an opposite end of the light-emitting plane of the transparent light guide, and prevents the opposite end of the light guide from being disengaged from the casing.

摘要： An object sensor is provided, which has a high object detection rate with respect to an object such as a raindrop adhering to a detection surface, and which is capable of detecting the presence/absence of an object with a high sensitivity. A light source 10, a detection surface 110, a focusing lens 40, and a plurality of photodetecting elements of a photodetecting unit 50 form a focusing system of equal magnification that is capable of catching an image in a size smaller than an object to be detected. Light emitted from the light source 10 is incident on the detection surface 110 via a prism 20 at a predetermined incident angle. Without a raindrop 120, the total internal reflection condition is satisfied as shown by a path 140 of a beam, so that the beam is subjected to the total internal reflection. Then, the beam passes through a prism 30, and is focused on a photodetecting surface of the photodetecting unit 50 by the focusing lens 40. On the other hand, with a raindrop 120, the total internal reflection condition is not satisfied as shown by a trail 130 of a beam, so that the beam passes therethrough and is not focused on the photodetecting unit 50. A difference in signal level is determined on the photodetecting element basis, so that an object covering the detection surface 110 is detected.
