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.

A document scanning apparatus for scanning a document is provided. The document scanning apparatus includes an image sensor unit which irradiates an incident light towards the document and generates image data by sensing a reflected light reflected from the document, a supporting unit which supports the image sensor unit, a movement unit which moves the image sensor unit between a scanning position and a calibration position, a housing which houses the image sensor unit, the supporting unit, and the movement unit, a transparent plate which transmits the incident light and the reflected light, a calibration sheet which is attached to a surface of the transparent plate, which is exposed to outside and is positioned in an area including the calibration position, and a housing cover which is coupled to the housing and seals inside of the housing.

A contact type image sensor comprises: a light source 3 to emit a light with a predetermined inclination angle for the direction of the normal line of the surface of an original at the position of a read line 9 in order to irradiate the light from both sides to the read line by one light source; an original supporting member 6 to support the original in order to lead the light from the light source 3 to the read line 9; and a photoelectric converting device section 5 to receive the light from the original surface. At least a part of the original supporting member 6 locating on the side opposite to the arrangement side of the light source 3 with respect to the read line 9 has a reflecting surface for reflecting a part of the light from the light source 3 and leading to the read line 9.

A contact type image sensor comprises a transparent member which can contact an original to be read, a light source for radiating light onto the original via the transparent member, a sensor for receiving light reflected by the original, an imaging element for imaging the reflected light on a light-receiving portion of the sensor, and support unit for supporting the sensor, the imaging element, the transparent member, and the light source. At least one of the imaging element and the light source is supported by the transparent member and the support unit.

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.
