    • A control circuit of an image reader having at least one light source includes: a light source control portion that controls ON and OFF of the light source by performing current switching for adjusting a value of a current supplied to the light source; a black reference data creating portion that creates black reference data used for shading correction under control of the light source control portion; an image reading portion that reads image data under control of the light source control portion; and a shading correction portion that performs shading correction of the image data using the black reference data. The black reference data creating portion adds a noise, which is equivalent to a noise added to the image data by the current switching, to the black reference data, and the shading correction portion removes the noise added to the image data by performing the shading correction.
    • 具有至少一个光源的图像读取器的控制电路包括:光源控制部分,通过执行电流切换来控制光源的导通和截止,以调节提供给光源的电流的值; 黑色基准数据生成部,其在光源控制部的控制下,生成用于阴影校正的黑色基准数据; 图像读取部,其在所述光源控制部的控制下读取图像数据; 以及阴影校正部分,其使用黑色参考数据执行图像数据的阴影校正。 黑参考数据创建部分将通过当前切换添加到图像数据的噪声等效的噪声添加到黑参考数据,并且阴影校正部分通过执行阴影校正来去除添加到图像数据的噪声 。

    • A light irradiation apparatus 10 is configured to comprise: a supporting means 11 for supporting a semiconductor wafer W as an irradiated object, the semiconductor wafer W being stuck with an adhesive sheet S having an ultraviolet curable adhesive on a circuit formation surface; and a light irradiating means 13 having a focus axis P at a location spaced by a predetermined distance, and being provided so as to enable head-swinging motion thereof. The supporting means 11 is supported by a multi-joint robot 12, and relatively displaces the wafer W so as to prevent an adhesive layer surface SA of the adhesive sheet S from deviating from a position of the focus axis P, when the ultraviolet ray irradiating means 13 performs the head-swinging motion.
    • 光照射装置10被构造为包括:用于支撑半导体晶片W作为被照射物体的支撑装置11,半导体晶片W在电路形成表面上粘附有具有紫外线固化粘合剂的粘合片S; 以及具有聚焦轴P位于间隔预定距离的位置处的光照射装置13,并且被设置成能够进行头摆动作。 支撑装置11由多关节机器人12支撑,并且当紫外线照射时,相对移动晶片W以防止粘合片S的粘合剂层表面SA偏离聚焦轴P的位置 装置13执行头摆动作。
