Abstract: An optical scanner includes a scanning optical system, a housing, and a pressing and retaining member. The housing includes a retaining portion, a support portion that is formed to be opposed to the retaining portion, and an engaged portion to be engaged with an engaging portion. The pressing and retaining member includes a main body including the engaging portion and at least one pressing portion. In a first state where the engaging portion is engaged with the engaged portion, the at least one pressing portion presses the optical element toward the retaining portion. While the pressing and retaining member shifts from a second state where the engaging portion is not engaged with the engaged portion to the first state, a distal end of the at least one pressing portion passes beyond a boundary between the retaining portion and the optical element and abuts on a part of the housing.

Abstract: An optical scanning device (15) includes a reference light guide part (50); a sub-light guide part (40); a reference holding structure (53) which includes a reference reception part (55) configured so as to be in contact with the reference lens (52) deflected in a sub-scanning direction; a sub-holding structure (45) which includes a sub-reception part (45) configured so as to be in contact with the sub-lens (42) deflected in the sub-scanning direction, wherein a deflection direction of the reference lens (52) coincides with a deflection direction of the sub-lens (42), and when it is assumed that the reference lens (52) and the sub-lens (42) are not deflected, an absolute value of a smallest distance between the sub-reception part (45) and the sub-lens (42) is set to be equal to or larger than an absolute value of a smallest distance between the reference reception part (55) and the reference lens (52).

Abstract: An optical scanning device includes a housing, a transmissive member, a wire-shaped member, a driving portion, a cleaning holder, a cleaning member, a stopper, and a control portion. The control portion is capable of executing a cleaning mode including at least one of a forward travel operation of controlling the wire-shaped member to travel in a first direction so that the cleaning holder moves along the transmissive member and a backward travel operation of, after executing the forward travel operation, controlling the wire-shaped member to travel in a second direction so that the cleaning holder moves in an opposite direction to a direction of the forward travel operation. The control portion executes a load releasing operation of controlling the cleaning holder to move by a prescribed amount in an opposite direction to the direction of the forward travel operation or the direction of the backward travel operation.

Abstract: A casing for an optical scanning device is configured to accommodate therein a scanning optical system. The casing includes a main body, a lid, a first positioning mechanism, and a second positioning mechanism. The main body includes an opening formed in an upper face. The lid closes the opening of the main body. The first positioning mechanism positions, when a plurality of the main bodies are stacked in a plurality of stages, the main body on an upper stage in a horizontal direction and a height direction, with respect to the main body on a lower stage. The second positioning mechanism positions, when a plurality of the casings, each having the lid attached thereto, are stacked in a plurality of stages, the casing on the upper stage in the horizontal direction and the height direction, with respect to the casing on the lower stage.

Abstract: An optical scanning device includes a housing that houses an optical system for generating a light ray for optical scanning, and has a dustproof glass for emitting the light ray to an outside, and a cleaning system that is assembled to the housing and cleans the dustproof glass. The cleaning system includes a cleaning member, and a holder that holds the cleaning member, and with the holder moved in a specified movement direction relative to the dustproof glass, the cleaning member cleans the dustproof glass. The cleaning member includes a cleaner member that is adapted to contact a surface of the dustproof glass, and a pressing member that has a pressing surface for pressing the cleaner member toward the dustproof glass and is formed of an elastic body. In the movement direction, a width of the cleaner member is wider than a width of the pressing surface.

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.

Abstract: A light deflecting device includes a rotary polyhedron and a cover that covers the rotary polyhedron. The cover includes an opening facing a peripheral surface of the rotary polyhedron. Light beam is irradiated to the peripheral surface of the rotary polyhedron through the opening of the cover, and the rotary polyhedron allows the light beam to be deflected and scanned with respect to an object to be irradiated while rotating about an axial center thereof. When an opening angle of the opening centered on the axial center of the rotary polyhedron is θ and n is set as a natural number, θ satisfies the following Equation (1) θ>((360°/the number of surfaces of the rotary polyhedron)×n)×0.83 . . . (1) and Equation (2) θ

Abstract: The calculation unit calculates the time interval between the time at detecting the light beam reflected by the reflective surface of the rotatory polyhedron incident on the BD sensor by the light beam detecting unit and the time at detecting the light beam reflected by the reflective surface incident on the optical sensor in the light source by the return light beam detecting unit. The scan adjusting unit adjusts the luminescence time of the light source for scanning the light beam on the surface to be scanned based on the time interval calculated by the calculation unit.

Abstract: An optical scanning device irradiates an image carrier with laser light to form an electrostatic latent image. The optical scanning device includes a casing, a transmissive member, a wire-shaped member, a driving portion, a guide rail, a cleaning holder, a cleaning member, and a stopper. The cleaning member is fixed to the cleaning holder and cleans the transmissive member by sliding with respect to the transmissive member along with movement of the cleaning holder. The stopper is disposed on one side of the guide rail in an extending direction of the guide rail and restricts the movement of the cleaning holder. Another side of the guide rail in the extending direction of the guide rail is open in the extending direction of the guide rail.
