摘要: An LED array device includes a plurality of LED units and a board for supporting the plurality of LED units. Each LED unit has a plurality of LED elements aligned straight in a predetermined pitch with a predetermined spacing between neighboring LED elements. The plurality of LED units are aligned straight with their end edges confronting each other such that an array of LED elements on one LED unit is in alignment with an array of LED elements on a next LED unit with the predetermined pitch being maintained. A spacing between an LED element positioned at the end of the alignment on the LED unit and the end edge of the LED unit is less than a half of the predetermined spacing.

摘要: An optical printer includes an optical printing head and a photosensitive member. Although quiet and fine printing can be performed when a light emitting diode array is employed as the optical printing head, there have been problems, on the other hand, such as difficulty in driving and difficulty in adjustment of primary factors directly affecting the printing quality such as uneveness in dot pitches and intensity. Therefore, the present invention copes with driving conditions by effectively distributing data transferring during static driving, thereby to improve the printing quality by selective printing timings.

摘要: A unit of arrayed light emitting diodes in accordance with the present invention is formed in a manner in which gold paste or the like is applied by screen printing on a substrate (11) to form an elongate printed conductor (12) having a thickness of less than 40 .mu.m, on which light emitting diode arrays (14) having a large number of light emitting areas (5) are disposed. The elongate printed conductor (12) comprises a plurality of printed thick films (121, 122 and 123), the lowermost thick film (121) for example being of a thickness of 10 .mu.m or less, so that both longer side edges of the thick film (121) may have good linearity. Accordingly, using the parallel longer side edges of the elongate printed conductor (12) as reference lines, a plurality of light emitting diode arrays (14) can be disposed with good linearity. In addition, by decreasing a resistance value per unit length of the elongate printed conductor (12) to 1.1 m.OMEGA./mm or less, the current capacity can be increased and the resistance can be lowered.
