Abstract: An optical scanning device has a light deflector deflecting a light beam from a light source, a synchronization detection sensor determining timing of starting scanning in main scanning direction based on timing of detecting the light beam scanned in main scanning direction by the light deflector, and a pre-sensor imaging optical system imaging the light beam reflected from the light deflector on the synchronization detection sensor. The pre-sensor imaging optical system moves the imaging position of the light beam on the synchronization detection sensor in a direction making the timing of detecting the light beam earlier or later according to whether variation in temperature causes the magnification of the scanning optical system in main scanning direction to increase or decrease respectively.

Abstract: An optical scanning device includes a light source, a deflector, an incident optical system and one scanning lens. The scanning lens includes a first face and a second face. In a main scanning direction cross section of the scanning lens, when a scanning range is separated, with on axis as a reference, into an image height region of a first direction and an image height region of a second direction that is opposite to the first direction, the incident optical system is disposed on a side of the image height region of the first direction. Curvature of the first face in a sub scanning direction cross section decreases from on axis toward off axis in the main scanning direction, and curvature of the second face in the sub scanning direction cross section increases from off axis of the first direction toward the second direction in the main scanning direction.

Abstract: A scanning optical apparatus includes a light beam detection unit, a reference signal generation unit, and a returned light detection unit. The light beam detection unit decides whether the light beam reflected by the reflecting surface of a polygon mirror has entered the BD sensor, through comparison between an output value of the BD sensor and a predetermined first threshold. The reference signal generation unit generates a scan start reference signal in response to the decision that the light beam has entered the BD sensor. The returned light detection unit decides whether the light beam reflected by the reflecting surface has entered the internal light sensor, through comparison between an output value of the internal light sensor and a second threshold corresponding to light beam intensity higher than the intensity of the light beam reflected by the reflecting surface and corresponding to the first threshold.

Abstract: An optical scanning device includes a light source which emits a light beam, a deflector, an incident optical system and one scanning lens. The deflector reflects and deflects/scans the light beam emitted from the light source. The scanning lens includes a first face facing the deflector and a second face on an opposite side to the first face, and performs imaging of the deflected/scanned light beam on a surface to be scanned. In a main scanning cross section, when an angle relative to an optical axis of an incident light beam which enters the scanning lens from the first face is θin, and an angle relative to an optical axis of an outgoing light beam which is output from the second face toward the surface to be scanned is θout, in an entire scanning region, a condition of 0.9

Abstract: A pressure retaining member is formed by bending a metal plate. The pressure retaining member includes: a body portion supported by a housing; and two pressing portions which are connected to the body portion, can be elastically deformed, and press an optical element toward a retaining portion of the housing. One of the two pressing portions is formed with a restriction portion which restricts a depth with which the other one of the two pressing portions enters between the two pressing portions of another pressure retaining member or a depth with which the body portion of the another pressure retaining member enters between the two pressing portions.

Abstract: Each of first and second glasses to be cleaned has a first edge and a second edge. A cleaning system has a cleaning member having a contact surface adapted to contact a surface of the glass, and first and second holders that hold the cleaning member. A drive system moves the holder so as to perform an outward cleaning moving from the first edge toward the second edge and a return cleaning returning from the second edge to the first edge. At a start position of the outward cleaning, the holder is stopped so that a portion of the contact surface of the cleaning member is positioned inside the first edge, and at a start position of the return cleaning, the holder is stopped so that a portion of the contact surface is positioned inside the second edge.
