Embodiment Construction

[0030] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures. Well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0031] 3 to 6 are an assembled view, an exploded perspective view, a longitudinal sectional view, and a front view, respectively, showing a hinge unit according to an embodiment of the present invention. Referring to these drawings, the hinge unit 10 includes a lower frame 110 and an upper frame 120 connected to the lower frame 110 through a hinge axis P. Referring to FIG.

[0032] The hinge unit may connect the cover of the image forming device with the scanning unit of the main body of the image forming device. In addition to re...

Abstract

A hinge unit applies resilience differently according to the angle at which the hinge unit is opened, and an image forming apparatus has a cover attached by the hinge unit. The hinge unit includes a lower frame connected to a scan unit of a main body of an apparatus; an upper frame engaged with the lower frame through a hinge shaft and connected to a cover; and first and second resilient members serially arranged within the upper frame. When the cover pivots toward the scan unit at less than a predetermined angle, the hinge unit provides relatively minor resistance, whereas when the cover pivots toward the scan unit at the predetermined angle or greater, the hinge unit provides relatively greater resistance, thereby appropriately coping with the moment by weight of the cover. As a result, the improved hinge unit may enable a user to open and close the cover more comfortably.

Description

technical field [0001] The invention relates to a hinge and an imaging device with the hinge unit. More particularly, the present invention relates to a hinge unit capable of smooth operation by applying elastic force varying with the opening angle of the hinge unit, and also devises a hinge unit having a cover connected to the main body of an image forming apparatus through the hinge unit. imaging device. Background technique [0002] Generally, an image forming apparatus having a scanning function, such as a copier, a scanner, and a multifunction device, scans a document and stores an image read from the document as data or prints out the image on a printing medium such as paper. [0003] FIG. 1 shows a conventional multifunctional device as an example of an imaging device. Referring to FIG. 1, the multifunctional device includes a scanning unit 2 formed on its main body 1 for reading an image from a document placed on the scanning unit 2; the multifunctional device also...
