摘要： A contact-type image sensor is designed to prevent, in an effective manner, dust from entering into a space between a rod lens array and a light receiving sensor. A rod lens array includes a large number of rod lenses between two flat substrates and between spacers located at left and right ends; one row of the rod lenses is arranged in such a way that central axes of the rod lenses become parallel to each other. At an emission side of a rod lens in an axis line direction, each substrate includes an extension portion, whose length is determined based on an operating distance of the rod lens. A lower end of the extension portion of each substrate is in contact with an upper surface of a sensor substrate. In this manner, the rod lens array is positioned with high accuracy with respect to the light receiving sensor.

摘要： A rod lens array includes a plurality of columnar rod lenses each having a refractive index distribution in which a refractive index continuously decreases from a central axis thereof to an outer periphery, and arranged in at least one row to align the central axes in parallel to each other. Each of the plurality of columnar rod lenses includes an emission-side end portion region, an incident-side end portion region, and an intermediate region between the emission-side end portion region and the incident-side end portion region, each having a central refractive index. The central refractive index of the incident-side end portion is equal to that of the emission-side end portion region in an optical axis direction, and the central refractive index at the intermediate region is higher than those of the emission-side and incident-side end portion regions.
摘要翻译：棒状透镜阵列包括多个柱状棒状透镜，每个具有折射率分布的折射率分布，折射率分布从折射率分布连续地从其中心轴向外周减小，并且布置在至少一排中以使中心轴线平行于每个其他。多个柱状棒状透镜中的每一个都包括发光侧端部区域，入射侧端部区域和发光侧端部区域与入射侧端部区域之间的中间区域，折射率。入射侧端部的中心折射率与光轴方向的发光侧端部区域的中心折射率相同，中间区域的中央折射率高于发光侧端部区域的中心折射率，侧端部区域。
