Printer

## Abstract

A printer includes a main body, a guiding plate secured within the main body, a cover rotatably connected to the main body and including at least one resisting block, and a shielding assembly arranged between the cover and the guiding plate. The printer includes a shielding plate rotatably connected to the main body and at least one elastic element secured to the shielding plate. The shielding plate is in an upright state when no external force is exerted on the shielding plate. When the cover is rotated to cover the main body, the resisting block resists the elastic element, causing the shielding plate to rotate from the upright state to a horizontal state, and causing a portion of the shielding plate to contact the guiding plate.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to printers.
2. Description of Related Art
A conventional inkjet printer includes a main body, a cover rotatably connected to the main body, a guiding plate to guide a printed paper to move out of the printer, an ink box disposed on the guiding plate, and a paper tray. The cover defines an opening. A printed paper can be ejected from the opening into the paper tray. When the cover is rotated to cover the main body, the space between the cover and the guiding plate is relatively great. When the printer is operating, ink from the ink box may fall into other elements of the printer through the space. Thus the printer may be contaminated by ink. Furthermore, foreign bodies may enter the ink box through the opening and the space to damage the ink box. Therefore, there is a need to provide a new printer to solve the above problems.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, a printer 100 includes a main body 10, a cover 20 rotatably connected to the main body 10, a guiding plate 30 secured within the main body 10, an ink box 40 disposed on the guiding plate 30, and a paper tray 50. The guiding plate 30 is used to guide a printed paper out of the printer 100 through an opening 21 defined in the cover 20 into the paper tray 50. In this embodiment, at least one resisting block 22 protrudes from the cover 20.
In this embodiment, the printer 100 further includes a shielding assembly 60. The shielding assembly 60 includes a shielding plate 62 and at least one elastic element 64 secured to the shielding plate 62. The shielding plate 62 is rotatably connected to the main body 10 and is arranged between the cover 20 and the guiding plate 30. Two opposite sidewalls (not labeled) of the shielding plate 62 respectively include shafts 620. The shielding plate 62 is rotatably connected to the main body 10 via the shafts 620. The shielding plate 62 is in an upright state when no external force is exerted on the shielding plate 62. When the cover 20 is rotated to cover the main body 10, the resisting block 22 resists the elastic element 64, causing the shielding plate 62 to rotate from the upright state to a horizontal state, and causing a portion of the shielding plate 62 to contact to the guiding plate 30. When the cover 20 is rotated to an open state, the resisting block 22 disengages from the elastic element 64, causing the shielding plate 62 to rotate from the horizontal state to the upright state.
In this embodiment, when the cover 20 covers the main body 10, the shielding plate 62 is in the horizontal state, thus the shielding plate 62 can prevent ink from the ink box 40 falling into and contaminating other elements of the printer 100. Furthermore, the shielding plate 62 contacts the cover 20 and the guiding plate 30 when in the horizontal state, thus preventing foreign bodies from entering the ink box 40 through the opening 21 while the ink box 40 is operating. A portion of the shielding plate 62 contacts the guiding plate 30 when the shielding plate 62 is in the horizontal state, thus the shielding plate 62 will not hinder a printed paper from ejecting from the printer 100. The shielding plate 62 is in the upright state when the cover 20 is in the open state, thus a user can conveniently replace the ink box 40.
Referring also to FIG. 4, the elastic element 64 includes a fixing end 642 and a free end 644. The fixing end 642 is secured to the shielding plate 62 with a fixing element 55. The free end 644 is bent toward the shielding plate 62. The fixing end 642 is farther away from the shaft 620 than the free end 644. In this embodiment, two elastic elements 64 are employed. The elastic elements 64 are substantially parallel to each other and respectively adjacent to the shafts 620. In this embodiment, the resisting block 22 includes an inclined sidewall 222 extending from the top of the resisting block 22. When the cover 20 covers the main body 10, the inclined sidewall 222 resists the free end 644 to cause the shielding plate 62 to be in the horizontal state and cause a portion of the shielding plate 62 to contact the guiding plate 30. In this embodiment, the cover 20 includes two resisting blocks 22 parallel to each other.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.

## Claims

1. A printer comprising:
a main body;
a guiding plate secured within the main body;
a cover rotatably connected to the main body and comprising at least one resisting block facing the guiding plate; and
a shielding assembly arranged between the cover and the guiding plate, and comprising a shielding plate rotatably connected to the main body and at least one elastic element secured to the shielding plate, wherein the shielding plate is in an upright state when no external force is exerted on the shielding plate, when the cover is rotated to cover the main body, the at least one resisting block resists the at least one elastic element, causing the shielding plate to rotate from the upright state to a horizontal state, and causing a portion of the shielding plate to contact the guiding plate, when the cover is rotated to an open state, the at least one resisting block disengages from the at least one elastic element, causing the shielding plate to rotate from the horizontal state to the upright state.
