In a light scanning method of scanning a light beam emitted from a light source on a plane to be scanned, a focal distance of an optical element that converges light emitted from the light source onto the plane to be scanned is sequentially varied to uniform a beam spot diameter at each position on the plane to be scanned where a distance from the light source varies.

Light scanning method and light scanning unit

There are provided a light-emitting device, an illuminating apparatus, and a display apparatus in which, in order to apply light to an object to be illuminated with uniformity in light intensity, the quantity of light which is applied to a part of an edge of a to-be-illuminated region of the to-be-illuminated object located near a light-emitting section can be lessened. A backlight unit includes a printed substrate, a plurality of light-emitting sections each of which has a base support, an LED chip and a lens, and reflective members each of which is placed around the light-emitting section and has a first wall portion and a second wall portion.

An embodiment of a paper feed apparatus is provided with a pressure varying mechanism that varies a load pressure of a pickup roller to originals. The pressure varying mechanism has a rotating lever that switches the load pressure, a rotating arm that contacts and presses against a swinging arm of the pickup roller, and a biasing portion that biases the rotating arm to the swinging arm when the rotating arm contacts to the swinging arm. When continuously reading a wad of originals in which different-size originals are mixed, due to a user operating the rotating lever, the load pressure to the originals is increased by making the rotating arm contact to the swinging arm such that the swinging arm is pressed by the biasing portion.

Paper feed apparatus

A document transporting device () serves as a platen cover to expose and cover platens (A,B). A document holder () is mounted on a predetermined mounting portion of the device (). A lateral end of the document holder () is withdrawn from a predetermined position where the end is located, so that a document transport path (R) is exposed through an area in which the document holder () has been withdrawn. The document transport path (R) is exposed to the left or the right with respect to the front of the device ().

Document carrying device, document reading device, and image forming device

According to the present invention, highly accurate adjustment of the angles and positions of optical elements constituting an optical scanning unit can be easily performed. For a cylindrical lens that makes the light beam for exposing a photoreceptor converge on the surface of the photoreceptor, a frame is provided for holding the cylindrical lens therein. The frame is supported by two support portions for a chassis of the optical scanning unit such that the longitudinal direction of the cylindrical lens becomes parallel to the scanning direction of the photoreceptor. The optical scanning unit is configured such that the angle of the cylindrical lens in the longitudinal direction is adjustable in the sub-scanning direction of the photoreceptor at the support portion on the front side (operational side) of these support portions.

A document reading device includes a document transport and, for reading a document image, an optical reader having a movable exposure which stops at a predetermined reading position and emits light onto the document. A guide member guides the document to the reading position to form a predetermined inclination angle with respect to a flat-plate face of a support, which supports the document being transported when it passes over the reading position. A transport path is formed with the support so that the document passing over the reading position is transported along the flat-plate face. A detection member detects a leading end position of the guide member, the predetermined reading position being set to within a predetermined distance in a transport direction from the leading end of the guide member, which is known beforehand to be stain-free.

Document reading device

A connecting apparatus of the present invention includes a cable used for electrically connecting an apparatus main body section to a section rotatably supported by a hinge member with respect to said apparatus main body section, wherein the cable is provided in parallel to a rotation axis of the hinge member so as to be held by the apparatus main body section and the section, respectively, and the cable has a half-loop shape. Because the cable is provided in parallel to a rotation axis of the hinge member so as to be held by the apparatus main body section and the section, respectively, the torsional stress is dispersed in the half-loop of the cable when the cable is twisted by a rotation of the section rotatably supported. On this account, the stress is not concentrated, thereby reducing the stress applied to the cable, and improving a durability of the cable.
