摘要： An optical scanning device that performs optical scanning across an object to be scanned with a light deflected, comprises: a deflection unit that causes a deflection mirror driven by a driving source to deflect the travel direction of light emitted from a light source and generates the light deflected; a resonator that includes a resonance space for reducing sound emitted from the deflection unit and a resonance passage communicating with the resonance space to direct sound from outside to inside the resonance space; a housing that accommodates the deflection unit and the resonator, and a partition wall that partitions a deflection unit accommodating space acting as a space for accommodating the deflection unit in the housing and a resonator accommodating space acting as a space for accommodating the resonator in the housing.

摘要： An optical scanning device includes a light source configured to emit a light beam; a rotary deflector configured to perform optical scanning by reflecting and deflecting the light beam emitted from the light source while rotating; an optical system forming member configured to form a path of the light beam; and a resonator having a resonance frequency corresponding to a sound generated by rotational drive of the rotary deflector. The rotary deflector is installed in a closed space. The resonator is installed so that the sound within the closed space is absorbed.

摘要： A light source unit includes a holder, a light source, coupling lens, and a support member. The light source is supported by the holder and projects a light beam against a target. The coupling lens adjusts an optical axis of the light beam. The support member contacts the holder and the coupling lens to fix the coupling lens in place on the holder after the coupling lens adjusts the optical axis of the light beam. The holder and the coupling lens are adhered to the support member using an adhesive agent. An optical scanner includes a rotary deflector to deflect and scan the light projected from the light source unit, a scan optical element to focus the light deflected by the rotary deflector, and the light source unit. An image forming apparatus includes the optical scanner.

摘要： An image forming apparatus includes an apparatus body including positioning faces; a detachably attachable unit including receiving parts and contact parts; and a biasing member to press the receiving parts of the detachably attachable unit to the positioning faces disposed on the apparatus body. The biasing member is rotatably disposed to the apparatus body, contacts the contact parts disposed on the detachably attachable unit, presses the receiving parts against the positioning faces, and is elastically deformable in a direction separating from a rotary supporting point of the biasing member; and when the biasing member is rotated to a locked state from a release state, the biasing member is hooked to the contact parts, so that the receiving parts are pressed toward the positioning faces by the biasing member.
