ABSTRACT:
An image sensor includes a frame 1, a light source unit 4 located in the frame 1 for irradiating light onto an original A to be read, a light receiving sensor 5 located in the frame 1 and including a plurality of light receiving portions arranged therein, and an optical system 6 located in the frame 1 for causing the light from the original A to be received by the light receiving portions in the light receiving sensor. The image sensor also includes at least one positioning portion formed in the frame 1 at an appropriate location and used to mount the light receiving sensor substrate 3 in the frame 1 and a stopper engaging and receiving portion 12 formed in the frame at an appropriate location. A leaf spring 2 has a stopper 21 formed thereon for detachably engaging the stopper engaging and receiving portion. The light receiving sensor substrate 3 properly positioned in the frame relative to the positioning portion 11 is resiliently biased against the frame. Thus, the light receiving sensor substrate can be detachably mounted and held in the frame.
