摘要： An optical pick-up device includes a laser diode, an objective lens for focusing a light beam emitted from the laser diode on an optical disc, an optical detector for receiving a reflected beam from the optical disc, a beam splitter for causing the light beam emitted from the laser diode and a reflected beam to pass therethrough or reflect, a front monitor for receiving the light beam emitted from the laser diode, and a front monitor light-guiding plate for guiding a part of the light beam emitted from the laser diode to the front monitor. The front monitor light-guiding plate is arranged between the laser diode and the objective lens and has a region having a predetermined shape for causing the part of the light incident thereon to change a traveling direction thereof by refraction and then reach the front monitor.

摘要： A cleaning device includes a cleaning blade disposed in contact with a rotator, a toner collecting section disposed along the rotator and the cleaning blade and includes a groove extending in an axial direction of the rotator, a conveyor disposed in the groove, and an agitator disposed on a side of a rim of the groove. The conveyor rotates to convey the toner in a longitudinal direction of the groove. The agitator vibrates through contact with the conveyor and includes comb-tooth portions lined in a comb shape in the longitudinal direction of the groove, and bent portions, each of which is bent from an end of one of the comb-tooth portions. The comb-tooth portions contact a circumference of the conveyor to vibrate. The bent portions are lined at intervals smaller than intervals on a base side of the comb-tooth portions.

摘要： A toner conveyance device includes a downward passage, a reciprocating member disposed in the downward passage, to move in a vertical direction in which the downward passage extends, a conveyance passage communicating with a lower end of the downward passage and extending in a direction crossing the vertical direction, a conveyor to rotate in the conveyance passage around an axis extending along the conveyance passage to transport the toner, and a flexible member projecting from a bottom of the reciprocating member toward the conveyance passage. The flexible member extends in the axial direction of the conveyor and moves together with the reciprocating member. When the reciprocating member is at a lowest position, a lower end of the flexible member opposes a portion of the conveyor downstream from an upper end thereof in a rotation direction thereof.
