ネジ等によシ画像読取装置本体に取り付けていた。In this type of system, an image reading device that inputs image information as an optical signal and outputs it as an electrical signal is an important device that influences the performance of the entire system. For this reason, there is a strong need to develop an image reading device with excellent performance. Along with this, an IJD array in which a plurality of LED chips are arranged has been newly used for illuminating the document surface of the image reading device due to problems such as miniaturization, cost reduction, and reduction in heat generation. In such an LED array, L
The light emitted from the ED chip is focused at the center of the light-receiving surface by a condensing lens, forming a peak in the illuminance distribution, but the peak of the illuminance distribution on the light-receiving surface is sharp, and the area where high illuminance can be obtained is at the center of the light-receiving surface. This L
When using an ED array to illuminate a document in an image reading device, the surface of the document must be the light-receiving surface, and the part of the document to be read must be aligned with the center of the light-receiving surface where the highest illuminance can be obtained. As a means of mounting and fixing,
The mounting hole drilled on the board is used for positioning,
It was attached to the main body of the image reading device with screws, etc.
