Description
- Sheet outputting devices—including printers, finisher, copiers, scanners, fax machines, multifunction printers, all-in-one devices, or other devices—process and output media such as plain paper, photo paper, transparencies, and other media. In some examples, sheet outputting devices can output media stacks of metals and polymeric media, such as Compact Discs, in addition to or instead of broad and thin media. Sheet outputting devices may output multiple sheets of media into an output tray.
- The following detailed description references the drawings, wherein:
-
FIG. 1 is a partial schematic view of a device according to an example. -
FIG. 2 is a partial schematic view of the device ofFIG. 1 according to an example. -
FIG. 3 is a partial schematic view of the device ofFIG. 1 according to an example. -
FIG. 4 is a partial schematic view of the device ofFIG. 1 according to an example. -
FIG. 5 is a partial schematic view of the device ofFIG. 1 according to an example. - In the following discussion and in the claims, the term “couple” or “couples” is intended to include suitable indirect and/or direct connections. Thus, if a first component is described as being coupled to a second component, that coupling may, for example, be: (1) through a direct electrical or mechanical connection, (2) through an indirect electrical or mechanical connection via other devices and connections, (3) through an optical electrical connection, (4) through a wireless electrical connection, and/or (5) another suitable coupling. The term “connect” or “connected” is intended to include suitable direct connections.
- A number of devices output media onto an output bin or tray for retrieval. The size of output media may vary. The speed at which devices process media has been increasing. For example, printing speeds and scanning speeds of devices are increasing. As a result, media is being output onto the output tray at increasing rates. However, as the speed of media ejection increases it becomes more difficult to control the tidiness of media on the output tray. Many media ejection systems include star wheels to contact a medium and drive it through the media ejection system. However, some systems may be designed such that a user could contact a star wheel during media retrieval resulting in an injury.
- To address these issues, in the examples described herein, a device is described which includes a flap to cover a star wheel and direct a medium onto an output tray. The device includes a media path to transport the medium to the output tray. In such an example, a star wheel is disposed to contact a medium being transported through the media path and drive the medium to the output tray. In operation, as the medium exits the media path, the medium may move the flap. The flap may be moved to a position to direct the medium towards the output tray as the medium exits the media path. In examples, the flap may contact a trailing portion of the medium and direct the medium towards a receiving surface of the output tray. In such examples, the flap may be positioned to cover a star wheel to reduce the risk of injury to a user retrieving media from the device.
- Accordingly, the present specification describes, in one example, a device that includes a star wheel to advance a medium along an output media path; and a flap disposed to cover the star wheel in a first position and to be moved by a force applied by a medium being advanced along the output media path to a second position, the medium to be directed toward an output tray when the flap is in the second position.
- In another example, the present specification describes an imaging device that includes a star wheel to advance a medium; a pinch roller disposed above the star wheel; an output tray to receive the medium; and a flap disposed to cover the star wheel and to rotate in response to a force applied by the medium to a position in which the flap directs the medium towards the output tray when the medium is unconstrained by the pinch roller and the star wheel.
- In yet another example, the present specification describes an imaging device that includes an axle coupled to the imaging device; a pinch roller coupled to the axle; a star wheel disposed below the pinch roller to form an end of a media path to advance a medium; an output tray to receive the medium; and a flap coupled to the axle and disposed to cover the star wheel in a first position and to rotate in response to a force applied by the medium to a second position in which a flap directs the medium towards the output tray.

FIG. 1 is a partial schematic view of adevice 10 according to an example.FIG. 2 is a partial schematic view ofdevice 10 ofFIG. 1 according to an example.FIG. 3 is a partial schematic view ofdevice 10 ofFIG. 1 according to an example.FIG. 4 is a partial schematic view ofdevice 10 ofFIG. 1 according to an example.FIG. 5 is a partial schematic view ofdevice 10 ofFIG. 1 according to an example. Theexample device 10 includes astar wheel 20 and aflap 30. In examples,device 10 further includes anaxle 40, apinch roller 50, and anoutput tray 80. In examples, a medium traveling throughdevice 10 may travel along amedia path 15 towardsoutput tray 80. In examples,star wheel 20,pinch roller 50, andflap 30 may be disposed to form an end ofmedia path 15. - In examples,
device 10 may be any device to output media which may be stacked on an output tray, such as an imaging device, a finisher, etc. An “imaging device” may be a hardware device, such as a printer, scanner, copier, multifunction printer (MFP), or any other device with functionalities to physically produce graphical representation(s) (e.g., text, images, models etc.) on paper, photopolymers, thermopolymers, plastics, fabric, composite, metal, wood, or the like. In some examples, an MFP may be capable of performing a combination of multiple different functionalities such as, for example, printing, photocopying, scanning, faxing, etc. In examples, media may be any type of paper, photopolymers, thermopolymers, plastics, fabric, composite, metal, wood, etc., which may be stacked on a receivingsurface 85 ofoutput tray 80 ofdevice 10. In examples,device 10 may output media alongmedia path 15. In examples,media path 15 may be an output media path or a media ejection path for media ejected bydevice 10. In examples, more than onestar wheel 20,pinch roller 50, andflap 30 may be disposed along the end ofmedia path 15. In such examples, the number and location ofstar wheel 20,pinch roller 50 andflap 30 may be selected for the particular use and design ofdevice 10. For example, the dimensions of various media traveling throughdevice 10 may determine the location ofstar wheel 20,pinch roller 50, and flap 30 at the end ofmedia path 15.

In other examples,output tray 80 may be a separate device coupled todevice 10. In examples,output tray 80 may include asurface 85 to receive multiple sheets or a stack of output media fromdevice 10. Various parameters related tooutput tray 80 may be selected for the particular use and design ofdevice 10. For example, the dimensions and orientation ofoutput tray 80 may be determined by the size of thedevice 10 and the particular use of the system. - In examples,
star wheel 20 may be disposed at one end ofmedia path 15. In examples, a star wheel may be used in various mechanical devices to convey components traveling through the device.

In such examples, a pinch roller may include a portion composed of a compressible material, such as rubber, urethane, foam, cloth, etc. In examples,pinch roller 50 may be any type of pinch roller to couple toaxle 40 and to rotate aboutcentral axis 45. In an example, medium 100 traveling alongmedia path 15 may contactpinch roller 50 andstar wheel 20. In an example,pinch roller 50 may be disposed to apply a force to medium 100 to advance medium 100 throughmedia path 15. For example,pinch roller 50 may apply a force tomedium 100 by compressing the compressible material ofpinch roller 50. In the examples ofFIG. 3 -FIG. 5 ,edium 100 is depicted as advancing alongmedia path 15 according to an example. In such an example, the force applied bymedium 100 as it is advanced alongmedia path 15 may rotatepinch roller 50 aboutcentral axis 45. In examples,pinch roller 50 may be disposed on top ofstar wheel 20 to constrain medium 100 as depicted inFIG. 4 . In such examples,pinch roller 50 andstar wheel 20 may constrain medium 100 until a trailing edge ofmedium 100 no longer contacts pinchroller 50 orstar wheel 20 as depicted inFIG. 5 . - In examples,
flap 30 may be disposed to coverstar wheel 20. In examples,flap 30 may be coupled toaxle 40. In examples,flap 30 may be disposed to coverstar wheel 20 in afirst position 5 in whichflap 30 may be resting under the force of gravity as depicted inFIG. 1 . In such an example,flap 30 may be in contact withstar wheel 20. In examples,flap 30 may be disposed to coverstar wheel 20 in asecond position 7 in whichflap 30 is rotate aboutcentral axis 45 depicted inFIG. 1 andFIG. 5 . In examples,flap 30 may be coupled toaxle 40 via arm 35 a and arm 35 b. In such an example, arms 35 a may be coupled toaxle 40 on one side ofpinch roller 50 and arm 35 b may be coupled toaxle 40 on an opposite side ofpinch roller 50. In examples,flap 30 may be coupled toaxle 40 by snapping arm 35 a and arm 35 b on toaxle 40. In examples,flap 30 may rotate freely aboutcentral axis 45 in response to a force applied thereon. - In examples,
flap 30 may rotate aboutcentral axis 45 in response tomedium 100 traveling alongmedia path 15. In such an example, the weight offlap 30 may be selected to allow medium 100 traveling alongmedia path 15 to rotateflap 30 aboutcentral axis 45. For example,flap 30 may weigh between 1 grams and 20 grams. In examples,flap 30 may apply a force to medium 100 todirect medium 100 towardsoutput tray 80. In such examples,flap 30 may be rotated tosecond position 7 to direct medium 100 towardsoutput tray 80 as depicted inFIG. 1 andFIG. 5 . In such an example,flap 30 may contact aportion 110 ofmedium 100 todirect medium 100 towardsoutput tray 80 whenpinch roller 50 andstar wheel 20 no longer constrain medium 100. - Referring now to
FIG. 3 -FIG. 5 , in examples, in operation,media 100 traveling alongmedia path 15 may be driven towardpinch roller 50 andstar wheel 20 as depicted inFIG. 3 . In examples, as depicted inFIG. 4 ,media 100 may contactflap 30 and apply a force to rotateflap 30 aroundcentral axis 45 fromfirst position 5, depicted inFIG. 3 , to an elevated position depicted inFIG. 4 . In examples, as depicted inFIG. 5 ,medium 100 is directed towardsoutput tray 80 byflap 30 when medium 100 is unconstrained bypinch roller 50 andstar wheel 20. In such an example,flap 30 may be disposed insecond position 7 to direct medium 100 towards receivingsurface 85 ofoutput tray 80. It will be understood thatsecond position 7 may be lower than the elevated position offlap 30 depicted inFIG. 4 because when medium 100 is unconstrained bypinch roller 50 andstar wheel 20flap 30 may rotate downward due to the force of gravity. - In examples,
flap 30 may be composed of any material with sufficient structural integrity to apply the downward force onmedium 100. For example,flap 30 may be composed of a metal, such as aluminum, a metal composite, such as steel, a plastic, a wood, a composite, such as carbon fiber, carbon reinforced plastics, glass-filled plastic, glass-filled nylon, glass-filled polycarbonate, glass filled acrylonitrile butadiene styrene (ABS), etc. Various parameters related toflap 30 may be selected for the particular use and design ofdevice 10. For example, the dimensions and location offlap 30 may be determined by the size of thedevice 10, the size and orientation of media to be stacked onoutput tray 80, the ejection rate of media ontooutput tray 80, and the particular use of the system. In an example, the number and locations offlap 30 indevice 10 may be chosen to allow variability in the dimensions of output media. For example,flap 30 may be dimensioned to contact different sized media, such as, A3 media or A4 media. - While certain implementations have been shown and described above, various changes in form and details may be made. For example, some features that have been described in relation to one implementation and/or process can be related to other implementations. In other words, processes, features, components, and/or properties described in relation to one implementation can be useful in other implementations. Furthermore, it should be understood that the systems, apparatuses, and methods described herein can include various combinations and/or sub-combinations of the components and/or features of the different implementations described. Thus, features described with reference to one or more implementations can be combined with other implementations described herein.
