摘要： An LED head for illuminating a surface of a photoconductive body includes an LED circuit board, lens assembly (SLA), SLA holder, base, and engagement member. The LED circuit board has LED arrays mounted thereon. The lens assembly has an optical axis and focuses light emitted from the LED arrays on the surface of the photoconductive body. The SLA holder has two opposing walls to hold the lens assembly therebetween. One of the opposing walls has a first reference surface with which the optical axis of the lens assembly is in a predetermined positional relation and urges the lens assembly against the other of the opposing walls. The base houses the LED circuit board and the SLA holder therein. The base has a second reference surface such that the optical axis is placed in position with respect to the LED arrays when the second reference surface is in intimate contact with the first reference surface. An engagement member holds the holder and the base together so that the first and second reference surfaces are in intimate contact with each other.

摘要： A method is used for correcting amounts of light of light emitting elements. A first correction range is defined which has a median of maximum and minimum values of the amounts of light of the light emitting elements, and includes a predetermined number of first subdivided ranges. If the minimum amount of light is not within the first correction range, a second correction reference is produced which is smaller than the first correction reference by a predetermined fraction of the difference between the maximum and minimum values. Then, a second correction range is defined which includes the minimum amount of light, has the second correction reference in its middle, and includes a predetermined number of second subdivided ranges. The amounts of light are corrected by increasing the amount of light if the measured amount of light is smaller than the second correction reference and decreasing the amount of light if the measured amount of light is larger than the second correction reference, the amounts of light being increased or decreased by the correction value corresponding to the second subdivided range. The first correction range may be set to include the minimum and maximum values therein, and the first and second subdivided ranges may progressively widen as the first subdivided ranges becomes increasingly far away from the first correction reference.

摘要： An LED print head is for use in an LED printer. The LED print head has an LED circuit board on which a plurality of LED chips are mounted in line, and a lens assembly having rod lenses for focusing light emitted from the LED chips on a surface of a photosensitive drum in the LED printer. A first member or slider engages either the LED circuit board or the lens assembly and is adapted to displace stepwise to cause either the LED circuit board or the lens assembly to flex stepwise relative to the surface of the photosensitive drum. A second member or slider engages said first member to movably hold said first member. The LED circuit board or lens assembly is flexed so that a point on the photosensitive drum and the surface of the corresponding LED form a pair of conjugate points with respect to the corresponding rod lens.
