Embodiment approach 1
[0032] Figure 4 It is a perspective view showing the main structure of a printer including the paper conveying device of the present invention.
[0033] like Figure 4 As shown, in the printer 10, a carriage shaft 13 is provided between the side frames 11a, 11b, and a carriage shaft 15 on which the print head 14 is loaded can move along the carriage shaft 13.
[0034] A platen 16 is provided below the carriage shaft 13 at an arbitrary position parallel to the carriage shaft 13 . The print head 14 is disposed facing the platen 16 , and a printing section is formed between the print head 14 and the platen 16 .
[0035] On the front side of the printing section in the paper conveyance direction, there is provided a table 17 as a paper feed tray, in which paper as a medium is placed. The paper is supplied to the printing section, and a paper conveying device as a medium conveying device is provided in the printer 10 . The direction in which paper is fed by the paper feeder is...
Embodiment approach 2
[0084] Figure 13 It is a side view showing the structure of the sheet conveying device according to Embodiment 2 of the present invention.
[0085] Unlike the first embodiment, the paper conveying device 40 of this embodiment adopts a structure in which a restricting member 46 is provided on the paper guide 45 .
[0086] In this embodiment, the same structures as in Embodiment 1 are marked with the same symbols, and detailed description thereof will be omitted.
[0087] like Figure 13 As shown, the paper transport device 40 of this embodiment has an upper paper feed roller 43 , a lower paper feed roller 24 , an upper paper guide 45 and a lower paper guide 26 .
[0088] As a medium guide, the upper paper guide 45 is provided above the lower paper guide so as to be swingable, and constitutes a paper guide as a paper transport path together with the lower paper guide. For the detailed shape of the upper paper guide in this embodiment, refer to Figure 14 .

Abstract
A medium conveying device includes a conveyance path that is used for conveying medium; a medium guide that is furnished on the conveyance path and has at least one swing supporting portion; and a supporting section that supports the swing supporting portion to swing along a separation direction separating from the conveyance path so as to make the swing supporting portion support the medium guide to swing.
Description
technical field [0001] The invention relates to a medium conveying device for conveying a medium and an image forming device having the medium conveying device, in particular to a medium conveying device and an image forming device capable of conveying a medium of any thickness. Background technique [0002] Conventional image forming apparatuses such as printers, copiers, and facsimile devices are provided with a medium transport device that transports paper as a medium, and transports paper supplied from a paper feed tray to an image forming unit. After the image forming unit forms an image on the conveyed paper, the paper is discharged to a paper discharge tray by the discharge unit. [0003] For example, Patent Document 1 below discloses a technology of a sheet conveyance device having a pair of guide members. In this sheet conveyance device, the upper guide member and the lower guide member are fixed in parallel to a side frame of the image forming apparatus, and a con...
