[0040] (First embodiment)
[0041] The following will refer to figure 1 Turning to FIG. 4, the first embodiment of the present invention will be described.
[0042] Such as figure 1 As shown, the printer 1 used as a liquid ejecting device includes a substantially parallelepiped frame 2. The paper feeding tray 3 is formed on the upper surface of the frame 2, and the paper output tray 4 is provided on the front surface of the frame 2. Each of the paper feeding tray 3 and the paper output tray 4 is configured to be accommodated in the frame 2 in a state of being folded with a hinge mechanism not shown.
[0043] The platen 5 extends longitudinally in the frame 2. The recording paper is inserted into the frame 2 via the paper feeding tray 3, and is supplied to the platen 5 by a paper feeding mechanism not shown. Then, the recording paper is conveyed from the frame 2 to the outside via the paper discharge tray 4.
[0044] The guide member 6 is provided in the frame 2 and extends in pa...

[0070] (Second embodiment)
[0071] The following will refer to Figure 5 with Figure 6 The second embodiment of the present invention is described.
[0072] In the second embodiment, similar to the check valve 14 of the first embodiment, the check valve suppresses the backflow of waste ink and air to the cap member 12. In terms of the installation position relative to the frame 2 of the printer 1, the check valve of the second embodiment is different from the check valve 14 of the first embodiment. Thus, the configuration of the check valve of the second embodiment is modified accordingly. Therefore, the following description focuses on the difference between the first embodiment and the second embodiment. The same or similar reference numerals are used to indicate the parts of the second embodiment that are the same or similar to the corresponding parts of the first embodiment.
[0073] Such as Figure 5 As shown, the gear pump GP is connected to the cover member 50 through a c...
