An object of the present invention is to provide an optical scanning device and an image forming device. The optical scanning device of the present invention has a housing. A plate-shaped rail part is protrudingly provided on the upper surface of the housing. The rail part extends along the screw shaft to guide the movement of the holding member. A guide part is provided in the holding member. guide groove. The optical scanning device further includes a scraper member that fixes the holding member and scrapes off foreign matter adhering to the rail portion. A collection container portion for collecting foreign matter scraped off by the scraper member is provided on the side surface of the casing on the moving end side. According to the optical scanning device and image forming apparatus of the present invention, while maintaining the linearity of the holding member, it is possible to prevent foreign matter from being caught on the sliding portion of the holding member and to prevent the foreign matter from falling from the upper surface of the casing.
Description
technical field [0001] The present invention relates to an optical scanning device and an image forming device having the optical scanning device. Background technique [0002] An image forming apparatus using electrophotography, such as a copier or a printer, has an optical scanning device for irradiating light to form an electrostatic latent image on a photoreceptor. [0003] The optical scanning device has a case that accommodates a polygon mirror, an imaging mirror, and the like. A light exit for emitting light is formed in the housing. The light exit is constituted by an opening extending in a predetermined direction. The light injection port is closed by a transparent cover such as dust-proof glass. [0004] However, if dirt, dust, etc., due to toner, etc., adhere to the surface of the transparent cover, the optical performance of the optical scanning device will decrease, resulting in a problem that the image will be unacceptable. In response to this problem, a pr...
