Abstract: Provided is an image scanning unit which makes it possible to improve scanning accuracy while also making the overall body thinner by appropriately positioning a plurality of reflection members within an effective space in a carriage frame without wasting space. An image scanning unit, wherein a frame is divided into at least two spaces facing an irradiation surface, a first accommodation unit for accommodating a light source unit is formed in one of the spaces, a second accommodation unit for accommodating at least one reflection member is formed in the other adjacent space, a first reflection member for initially receiving light reflected from the irradiation surface is positioned at the side opposite the irradiation surface with the first accommodation unit positioned therebetween, and a light-shielding member is provided between the first reflection member and the reflection member positioned in the other space and prevents light that has strayed from a scanning light path from the first reflection member from being incident on the reflection member in the other space.

Abstract: A lighting device includes a light source that illuminates an object of illumination, a reflecting member provided opposite the light source so as to direct a first part of illuminating light emitted therefrom to the object of illumination, and a light-blocking member provided between the light source and the object of illumination and between the reflecting member and the object of illumination. The light-blocking member blocks the first directed part of the illuminating light and a second part of the illuminating light directly illuminating the object of illumination with a certain ratio of a light-blocking rate for the first directed part of the illuminating light to a light-blocking rate for the second directly illuminating part of the illuminating light.

Abstract: In an image sensor including a light emitting element for emitting a light beam to be incident on a document, a light receiving element for receiving the light beam reflected by the document, and a lens array for directing the reflected light beam from the document to the light receiving element, there is located a mirror between the lens array and the light receiving element for changing the direction of the light beam passing through the lens array. The light emitting element and the light receiving element are located on the same substrate. With this arrangement, a compact and inexpensive image sensor can be achieved. This compact image sensor causes an increased amount of light to be incident on the document.
