[0034]

[0035] figure 1 Is a perspective view of the image forming apparatus 1 according to the first embodiment of the present invention, figure 2 It is a cross-sectional view showing the internal structure of the image forming apparatus 1. in figure 1 In, not shown figure 2 The automatic document feeder 20 and the conveying unit 55 are shown. In addition, although the figure shows a complex machine equipped with a printing function and a copy function as an example of the image forming apparatus 1, the image forming apparatus may be a printer, a copying machine, or a facsimile device.

[0036] The image forming apparatus 1 includes an apparatus main body 10 (housing) having an approximately rectangular parallelepiped casing structure, and an automatic document feeder 20 arranged on the apparatus main body 10. Inside the apparatus main body 10 are housed: a reading unit 25 that optically reads a document image to be copied; an image forming section 30 that forms a toner image...

Abstract

The sheet feeding device includes a housing, first and second feeding paths, and first and second covers. The first feeding path extends in a vertical direction within the housing. The second feeding path extends in the vertical direction within the housing, and a lower end thereof is connected to an upper end of the first feeding path. The first cover, in which an upper side is openable/closable relative to the housing with a lower side as a fulcrum, exposes, in an open state, the first feeding path outside of the housing. The second cover, in which an upper side is openable/closable relative to the housing with a lower side as a fulcrum, exposes, in an open state, the second feeding path outside of the housing. When both the first cover and the second cover are opened, the first cover and the second cover are respectively in the open state relative to the housing in a mode where a second opening angle of the second cover relative to the housing is smaller than a first opening angle of the first cover relative to the housing.

Description

technical field [0001] The present invention relates to a sheet conveyance device and an image forming apparatus including the same. Background technique [0002] In an image forming apparatus that forms an image on a sheet, a toner image is formed on a photosensitive drum by an image forming unit, and the toner image is transferred at a transfer nip formed between the photosensitive drum and a transfer roller. Print onto sheet. The image forming apparatus further includes a fixing unit, and the sheet on which the toner image is transferred is subjected to fixing processing in the fixing unit, and then discharged to the outside of the apparatus. [0003] Since the image forming apparatus described above uses sheets of different sizes, a sheet conveying device including a multi-layer sheet cassette is disposed below the image forming section. Sheets delivered from the respective sheet cassettes are supplied to a sheet transport path extending in the vertical direction on on...
