Abstract
An output mechanism for transferring a print medium is disclosed. The output mechanism includes an output tray, a stand connected to the output tray, a roller assembly rotatably coupled to the stand, and a block member connected to the stand adjacent to the roller assembly. The roller assembly transfers the print medium onto the output tray. The block member contacts an end of the print medium and allows the print medium to be curl upward.
Description
- 1. Technical Field
- The present disclosure relates to an output mechanism which can prevent a print medium form curling downward.
- 2. Description of Related Art
- Many printers include an output mechanism for outputting a printed print medium, such as a sheet of paper. The print medium tends to curl downward because of its gravity after being processed by the printer. Thus, it is desirable to provide an output mechanism which can prevent the print medium from curling downward.
- Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is a cross-sectional view of an output mechanism according to an exemplary embodiment. -
FIG. 2 is a cross-sectional view of the output mechanism ofFIG. 1 , showing that the output mechanism is outputting a print medium. - Embodiments of the present disclosure are now described in detail, with reference to the accompanying drawings.
- Referring to
FIG. 1 , anoutput mechanism 1 of a printer includes anoutput tray 11, astand 12 disposed on theoutput tray 11, aroller assembly 20 rotatably coupled to thestand 12, and ablock member 30. Therolling assembly 20 is used to transfer aprint medium 2 onto theoutput tray 11, and theblock member 30 is used to prevent theprint medium 2 from curling downward. - In the embodiment, the
roller assembly 20 includes afirst roller 21 and asecond roller 22 which cooperatively define agap 23. Thefirst roller 21 and thesecond roller 22 can be driven by a driving mechanism (not shown) to rotate respectively around an axis of their own. - The
block member 30 includes a fixedportion 31 and anangled portion 32. - The
fixed portion 31 protrudes from thestand 12. Theangled portion 32 defines a distal,free end 33 whose position is lower than that of thegap 23 when being measured from theoutput tray 11. In the embodiment, theblock member 30 is L-shaped and made of flexible material. - Referring to
FIG. 2 , when thefirst roller 21 and thesecond roller 22 respectively rotate around their axes, theprint medium 2 is transferred through thegap 23 as driven by thefirst roller 21 and thesecond roller 22. During the transfer, the front end of theprint medium 2 will contact theangled portion 32 of theblock member 30. The processedprint medium 2 is then curled upward. After that, theprint medium 2 is dropped onto theoutput tray 11, and theoutput mechanism 1 prevents theprint medium 2 from curling downward. - While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
Claims (3)
1. An output mechanism for transferring a print medium, comprising:
an output tray;
a stand connected to the output tray of the output mechanism;
a roller assembly comprising a gap and configured to transfer the print medium onto the output tray through the gap; and
a block member comprising a distal, free end lower than the gap when being measured from the output tray, causing the print medium to be upward curled before the print medium reaches the output tray.
2. The output mechanism as described in claim 1 , wherein the roller assembly comprises a first roller and a second roller rotatably coupled to the stand, wherein the gap is formed between the first roller and the second roller.
3. The output mechanism as described in claim 2 , wherein the block member is made of flexible material.
