Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. and. In the following drawings, the scale of each member is appropriately changed in order to make each member a recognizable size.

[0026] figure 1 is a perspective view of an optical scanning device as an example viewed obliquely from above, figure 2 is the plan view of the same optical scanning device, image 3 yes figure 2 The A-A line profile.

[0027] In these figures, reference numeral 1 is an optical scanning device. This optical scanning device 1 is installed in an image forming device such as an electrophotographic copying machine or a printer (particularly such as image 3 The laser scanning unit (Laser Scanning Unit, LSU) of a color image forming device in which a plurality of photosensitive drums (image carriers) 20 are formed side by side is shown. and, image 3 The illustrated color image forming apparatus is an example of an image forming appara...

Abstract

The present invention provides an optical scanning device and an image forming device. The optical scanning device of the present invention has a plurality of automatic cleaning units that automatically clean the dustproof glass. The automatic cleaning part has a screw shaft, and the screw shaft is arranged along the dustproof glass and spirally passes through the holding member holding the cleaning member. When the screw shafts of each automatic cleaning part are simultaneously driven and the holding member moves, the The height of at least one cleaning member with respect to the said dustproof glass is comprised so that it may differ from other automatic cleaning parts. According to the present invention, the load applied to a driving source such as a motor during cleaning is reduced and suppressed, whereby a relatively inexpensive motor can be used.

Description

technical field [0001] The present invention relates to an optical scanning device and an image forming device. Background technique [0002] In an image forming device such as an electrophotographic copier or a printing machine, the light for writing an electrostatic latent image from an optical scanning device is irradiated to a photoreceptor (image carrier) uniformly charged by a charging device. After the electrostatic latent images are formed on the bulk, each electrostatic latent image is developed using toner by a developing device to be developed as a toner image. [0003] The optical scanning device accommodates a scanning optical system that emits light for writing an electrostatic latent image to a photoreceptor. The light scanning device has an emission port for light emitted from the scanning optical system, and a dustproof glass (glass cover) covering the emission port. For example, a color image forming device corresponds to four colors of magenta (M), cyan ...
