Problems solved by technology
In this case, although the installation space of the imaging device as a whole does not increase, the arrangement design in the main body of the imaging device is very restricted.
In addition, the imaging device needs to be designed taking into account the attached duplex unit, thus complicating the imaging device itself
In addition, since the manual sheet feeder is supported on the duplex unit, the weight of the duplex unit itself increases, and handling of the duplex unit becomes difficult.

Embodiment Construction
[0024] The embodiments of the present invention will be described in detail below. In addition, it should be pointed out that in this specification, "one side" of the main body of the imaging device refers to all sides except the upper side and the bottom side, including the front side and the back side.
[0025] figure 1 is a schematic sectional view of the imaging device 1 in the embodiment of the present invention. figure 2 is a schematic cross-sectional view of a state where an inversion conveying unit is installed in the image forming apparatus 1 . A document reading unit 2 is provided in an upper portion of the imaging device 1 . A paper feeding unit 3 and a printing unit 4 are sequentially arranged in the lower portion of the image forming apparatus 1 from the bottom side.
[0026] In the document reading unit 2 , a paper holder 11 is disposed on a cover portion 10 . The document placed on the paper holder 11 is transported to a position facing the reader by a conv...

A duplex image forming device includes an image forming device and a reversible transportation unit. The image forming device includes a paper transportation path, a paper feed unit which transports a paper to the paper-transportation path, a printing unit which prints an image onto the paper, a discharge tray where the paper printed with the image is discharged, a manual paper feed tray which is attached to a side of the image forming device, and a storage opening which is provided at a side of the image forming device and stores the manual paper feed tray. The reversible transportation unit is inserted into a side of the image forming device to cover the upper part of the storage unit. The reversible transportation unit includes a reversible transportation path for transporting out to an upstream side of the printing unit, the paper transported from the downstream side of the printing unit of the paper transportation path. The reversible transportation path is formed by passing through the storage opening.
Description
technical field [0001] The present invention relates to an image forming device, such as a copier and a facsimile machine, in particular to a reversing conveying unit for forming images on both sides of paper and an image forming device in which the reversing conveying unit can be inserted . Background technique [0002] In order to form images on both sides of a sheet, there has been provided a reversing conveying path for reversing the sheet in the sheet conveying path. After an image is formed on one side of the paper, the paper is conveyed into a reverse conveyance path, and the two sides of the paper are reversed, thereby forming an image on the other side of the paper. When such a conveyance path for paper inversion is provided in the main body of the image forming device, the space inside the image forming device needs to be increased. Therefore, when an image needs to be formed on each side of a sheet, a reverse conveying unit can be inserted into the main body of ...
