位置決め装置。[Claims for Utility Model Registration] 1. An image that has a light source and an image sensor that receives the light emitted from the light source and outputs a corresponding output by receiving the reflected light from the surface of the subject, and can be used as a handy type. In an image scanner equipped with a paper feeder section that incorporates this image scanner section and can also be used as a sheet-through type, before the object is conveyed to a certain area facing the image sensor. The image data read by the image sensor from the range part is compared with the image data read by the image sensor from the leading position of the subject when the subject is transported to the range part, and image data based on the comparison result is obtained. 1. A subject leading positioning device for an image scanner, comprising: a subject leading position positioning section that determines the leading position of the subject based on a difference in the number of objects. 2. In an image scanner that has a light source, an image sensor that receives reflected light from the light source and outputs a corresponding output by receiving reflected light from the surface of the object, and has a drive mechanism for transporting the object, is not conveyed to a certain area facing the image sensor, the image data read by the image sensor from the area, and the subject is conveyed to the area, and the image sensor reads the image data from the leading position of the subject. A subject head positioning device for an image scanner, comprising a subject head positioning section that compares the image data to be read and determines the head position of the subject based on a difference in the image data as a result of the comparison.
