摘要:
A light guide (11) includes: an incident surface (18), an exit surface (17) and two reflective surfaces (1501, 1502). The incident surface (18) allows light emitted from a light source (12) to be incident thereon. The exit surface (17) extends in a main scanning direction and allows the incident light to exit the light guide (11) therethrough. Two reflective surfaces (1501, 1502) are located opposite to the exit surface (17) to extend in the main scanning direction and are configured to reflect the incident light toward the exit surface (17). One (1501) of the reflective surfaces includes a plurality of light reflecting patterns (16) formed integrally therewith and having an oval hemispherical prism shape. The other reflective surface (1502) is a separate surface from the one reflective surface (1501) and is formed in a planar shape that enables attachment of a reflective member (1521) allowing the incident light to be reflected thereon toward the exit surface (17).

An image forming apparatus (100) includes a job executing portion (108), a mode setting portion (110), and an operating portion (109). The operating portion (109) accepts a function unit setting operation for setting a job executing mode in a function unit, the mode setting portion (110) sets the job executing mode in the function unit based on the function unit setting operation accepted by the operating portion (109), and the job executing portion (108) executes a job in the job executing mode set by the mode setting portion (110).
摘要:
The invention relates to an image forming apparatus (100) that has two job executing modes - a usual mode for executing a job at a predetermined usual processing speed; and a quiet-sound mode for raising quietness during a time of executing a job by executing the job at a quiet-sound processing speed slower than the usual processing speed. A mode setting portion (110) to set the job executing mode and an operating portion (109) configured to accept an operation for setting the job executing mode are provided. The operating portion (109) includes a display portion (91) having a usual mode key (NK2) and a quiet-sound mode key (SK2). When the usual mode key (NK2) operated, the mode setting portion (110) sets the job executing mode of the executing target job to the usual mode, and if the quiet-sound mode key (SK2) is operated, the mode setting portion (110) sets the job executing mode of the executing target job to the quiet-sound mode.
