Optical scanning device and image forming apparatus using the same

#The present patent application claims priority from Japanese Patent Application No. 2007-051317, filed on Mar. 1, 2007 in the Japan Patent Office, the entire contents of which are hereby incorporated herein by reference.

#1. Technical Field

#Example embodiments generally relate to an optical scanning device and an image forming apparatus using an electrophotographic method, such as a copier, a printer, a facsimile machine, and a multifunction apparatus that combines the functions of the copier, the printer, and the facsimile machine.

#A more complete appreciation of example embodiments and the many attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:

#FIG. 1 is a schematic view illustrating a printer according to example embodiments;

#FIG. 2 is an enlarged schematic view illustrating an image forming unit in the printer illustrated in FIG. 1;

#The accompanying drawings are intended to depict example embodiments and should not be interpreted to limit the scope thereof. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted.

#It will be understood that if an element or layer is referred to as being “on”, “against”, “connected to”, or “coupled to” another element or layer, then it can be directly on, against, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, if an element is referred to as being “directly on”, “directly connected to”, or “directly coupled to” another element or layer, then there are no intervening elements or layers present. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

#Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, term such as “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein are interpreted accordingly.
