摘要：
An image sensing head including a block, a multiplicity of light emitting optical fibers, a multiplicity of light receiving optical fibers, a multiplicity of light emitting elements connected to the light emitting optical fibers and a multiplicity of light receiving elements connected to the light receiving optical fibers. A thin sheet formed with an opening in a portion thereof which faces the sensing end portions of the light emitting and light receiving optical fibers is attached to one side of the image sensing head, so that a predetermined clearance can be maintained between the sensing side end portions of the light emitting and light receiving optical fibers and a document surface to be sensed by the image sensing head.
