摘要： Top surfaces and inclined surfaces of prisms on a side opposite to a light source are formed such that, in a region on a light source side, light traveling in a light guide body toward the side opposite to the light source is sequentially reflected by the top surfaces and the inclined surfaces of the side opposite to the light surface of the prisms and approaches a direction orthogonal to the longitudinal direction of the light guide body. The height of the prisms can be the lowest in the longitudinally central portion of the light guide body, and gradually increases toward the light source side and the side opposite to the light source, from the central portion.

摘要： To provide an image forming apparatus capable of preventing a fluctuation in image density immediately after the light quantities are corrected, and a method for controlling the same, when light quantity measurement is carried out at time t1, the controller CPU calculates the light quantity correction value ND. Herein, it is assumed that the light quantity correction value ND calculated previously, which is the light quantity correction value before light quantity measurement at time t1, is NDold, and the light quantity correction value ND calculated based on the light quantity measurement value at time t1 is NDnew. When the light quantity correction NDnew is calculated, the controller CPU varies the light quantity correction value ND from the light quantity correction value NDold a plurality of times by a predetermined variation value α in the direction approaching the light quantity correction value NDnew for each of the printing sheets.

摘要： A document scanning device includes a pair of light guides that extend in a main scanning direction of a document and illuminate the document, and a reference plate that is positioned closer to the light guides than the document. Each of the light guides has a first area that illuminates the document and a second area that illuminates the reference plate. Each light guide illuminates the reference plate over a wider area between the light guides in the second area than each light guide illuminates the document in the first area. Therefore, the center of the reference plate is illuminated and a sufficient amount of light is reflected on the reference plate.

摘要： When a driving current value of at least one light emitting element (an organic EL element) has reached a correction limit current value, a controller CPU of a controller constituting a light intensity correcting unit does not correct the light intensity of the light emitting element. Alternatively, the controller CPU may correct the light intensity of the light emitting elements other than a reference light emitting element on the basis of the light intensity of the reference light emitting element using the light element of which the driving current value is greatest as the reference light emitting element. Alternatively, the controller CPU may correct the light intensity of the light emitting elements other than a reference light emitting element on the basis of the light intensity of the reference light emitting element, using the light emitting element of which the light intensity is smallest when the entire light emitting elements are driven with the same driving condition as the reference light emitting element.
