摘要： An optical writing device includes a polygon mirror configured to guide a light beam emitted from a light source. The polygon mirror is disposed in a case. The case includes a cover unit and a pressure unit configured to exert pressure on the cover unit. Pressure exerted by the pressure unit on the cover unit is greater than pressure exerted on another portion of the cover unit.

摘要： Applicable rules (IF-THEN rules) are generated with use of predetermined membership functions concerning input and output variables in response to entry of input and output values. Accordingly, time and labor required to make rules can be simplified. In addition, it can be also verified, by making fuzzy inferences according to the generated rules, whether or not the rules are appropriate.

摘要： An optical scanner includes a light source, an optical element, a deflector, a casing, and a first cover. The deflector deflects the light beam emitted from the light source to scan a photoreceptor through the optical element. The casing includes an upper opening, walls including a transparent plate defining a deflector compartment to accommodate the deflector, and an optical element mounting portion to accommodate the light source and the optical element. The first cover covers the upper opening of the casing and includes a recessed portion recessed toward the bottom of the casing and including a first opening at the bottom thereof facing the deflector. The recessed portion and the walls are directly or indirectly connected to define a single continuous space isolating the deflector compartment from the optical element mounting portion. The recessed portion and the deflector compartment communicate via the first opening.
