Abstract: PROBLEM TO BE SOLVED: To ensure a desired spot size at all times for all LED elements while taking account of the difference of beam profile among respective LED element regardless of the characteristics of a photosensitive body and the image forming conditions and to eliminate longitudinal streak or uneven density. SOLUTION: Even if image forming conditions are modified to conform to the characteristics of a photosensitive body being used, a preset corresponding correction data is read out from a memory section 15 while taking account of a case where other proximate LEDs 3 are lighted simultaneously by a correction data reading means depending on the image forming conditions when a desired spot size is determined. A drive control means controls lighting operation of the LED 3 using the correction data to ensure a uniform optical writing providing a desired spot size. According to the arrangement, an image having no longitudinal streak nor fluctuation of density can be obtained even when proximate LED elements 3 are lighted simultaneously to print a longitudinal line.

Title: Worm gear device
Inventor: MOCHIZUKI MASANORI
IPC: F16H1/16
Filed: 1989-11-29
Abstract: PURPOSE:To prevent the occurrence of a backlash by a method wherein first and second gear members having rollers brought into contact with the respective flanks on the advancing side and the following side of a worm tooth are alternately disposed on an outer periphery through an energizing means. CONSTITUTION:In a wheel H and a worm 1, a set of first and second tooth members 2a and 2b are geared with a tooth 11, a roller 20 of each tooth member is rotated around a stem part 22, and rotation of the worn 1 is transmitted to the wheel H. The roller 20 of the first tooth member 2a is brought into contact with the flank on the advancing side of a tooth 11 and the roller 20 of the second tooth member 2b is brought into contact with the flank on the following side of the tooth 11. A protrusion force is exerted in the radial direction of the wheel H on the tooth member through the energizing force of an energizing means located between the bottom part of a hole 31 and the tip of the stem 22. Thus, since the tooth 11 is nipped by means of a set of the first and second tooth members 2a and 2b, the backlash of a gearing part is prevented from occurring. Even when the gearing part is worn due to a long term use, gearing prevented from the occurrence of a backlash is ensured.
