Embodiment Construction

[0015] Embodiments of the present invention will be described below based on the drawings.

[0016] reference from Figure 1 to Figure 3 Embodiments of the present invention will be described. figure 1 is a schematic diagram showing the internal structure of an image forming apparatus including the document scanning apparatus of the present invention. figure 2 An enlarged view showing the first frame. image 3 It is a side view showing the first frame with the original pressure plate opened.

[0017] The digital copying machine 50 (which is an example of the image forming apparatus of the present invention) has a first frame 60 and a second frame 100 which assemble a plurality of parts for reading an image recorded on a document. Wherein, the second frame assembles a plurality of components for forming an image on the recording medium, and as shown in the figure, the second frame 100 is disposed below the first frame 60 . Therefore, the first frame 60 is placed on the sec...

Abstract

A document scanning device comprising: a loading plate on which an original is placed; a scanning unit which moves relative to the loading plate and scans the original; a separator member which slides and rubs on the loading plate and limits The interval between the aforementioned loading plate and the aforementioned scanning unit: the aforementioned spacer member is in contact with the aforementioned loading plate in a line contact manner along the moving direction of the aforementioned scanning unit.

Description

technical field [0001] The present invention relates to a scanning device for reading an image of a document. Background technique [0002] Conventionally, an image forming apparatus has been used to read an image recorded on a document (document image) and form the read document image on a recording medium such as recording paper. As a method (mode) of reading an original image, there are known a so-called original fixed scanning mode and an image moving reading scanning mode. [0003] In the image moving reading scanning mode, for example, a contact image sensor (hereinafter referred to as CIS) that reads the original image is placed stationary under the original platen glass, and on the one hand, the original is passed through the upper surface of the CIS in the original platen glass. area (image reading area), on the one hand to read the original image, on the other hand, in the original fixed scanning mode, place the original on the original table glass, on the one han...
