Abstract
A printer including an input tray including a input print media support surface and an output tray including an output print media support surface separate from the input print media support surface of the input tray, wherein the output tray nests in the input tray or the input tray nests in the output tray when the input tray and the output tray are in the closed position, and wherein the input tray is configured to prevent input print media in the input tray that has not been circulated through the printer from contacting output print media in the output tray that has been circulated through the printer.
Description




BACKGROUND OF THE INVENTION




Printers have become ubiquitous in office and home environments. Some common applications are for desktop printing of computer generated documents. Prior art printer architectures are not designed for minimizing a printer foot print when the printer is positioned on a desk or other support structure. Further, prior art printer architectures are not designed for minimizing shipping volume.




It would be an advantage to provide a printer with low foot print and/or a small footprint and/or a printer that minimizes a volume needed for shipping and/or while providing media trays of substantial strength.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS




Reference will now be made in detail to various embodiments of the present invention. An effort has been made to use the same reference numbers throughout the drawings to refer to the same or like parts. Directional and spatial language, such as upwards and bottom, is frequently used herein. This language for the exemplary embodiments is intended to be interpreted in view of a printer sitting on a table and ready to print, where the printer is in a fully deployed configuration.




In a first embodiment of the present invention, as seen in

FIGS. 1-13

, there is a printer


100


comprising an input tray


200


and an output tray


300


. In some embodiments of the invention, these trays are full input trays and full output trays, while in others, these trays are not full input trays and full output trays. By “full input tray” and “full output tray,” it is meant trays for a printer that support print media used in a printer in a manner that prevents pre-printed media in one tray from contacting printed media in another tray, based on the print media size that is to be typically utilized in the printer. That is, a full input tray prevents input media (e.g. paper that has not been circulated through the printer) in a full input tray from contacting output media (e.g. paper that has circulated through the printer) in the output tray, and visa-versa. (Of course, this does not include trays that prevent a piece of print media from contacting the media on the input tray and the output tray while the piece of print media is circulating through the printer, since in some printers, the top of the print media can be in the output tray while the bottom of the media can still be in the input tray.) Full trays can be differentiated from trays formed from, for example, a stub that only supports a small portion of the surface area of print media, which, in the case of an input tray positioned below the output tray, permit at least some of the unsupported portions of output media (e.g. portions not in contact with the stub) to contact the input media.




The input tray


200


and the output tray


300


can include respective input and output print media support surfaces


210


and


310


. In the first embodiment of the present invention, the support surfaces


210


and


310


are configured to support an entire piece of print media having dimensions 8½ inches by 11 inches, such as a conventional standard size paper and/or A4 paper. In some embodiments of the invention, the support surface


310


includes a surface formed by extending the output stop


330


(discussed in greater detail below) while in other embodiments, the support surface


310


does not include a surface formed by extending the output stop


330


. In other embodiments of the present invention, the support surfaces


210


and


310


only support a portion of a piece of print media having dimensions 8½ inches by 11 inches. In some embodiments of the present invention, the support surfaces are flat, while in other embodiments of the present invention, the support surfaces are curved. Still further, in other embodiments of the present invention, the support surfaces have cavities where a portion of the print media is not supported. By way of example only and not by limitation, the cavity


320


for the output stop


330


of the output tray


300


(discussed in greater detail below) could result in portions of the output print media not being supported by the output print media support surfaces


310


. This could also be the case with the input print media support surface


210


.




According to the first embodiment of the present invention, the input tray


200


and the output tray


300


can be configured to rotate from a open position to a closed position.

FIG. 10

illustrates rotation of the trays of an embodiment of the present invention from the open position to the closed position. However, in other embodiments of the present invention, the trays


200


and


300


can be open and closed in a different manner. In this regard, some embodiments of the present invention can be practiced by utilizing any means that will result in the opening and the closing of the trays of the printer.




In the first embodiment of the invention, the input print media support surface


210


of the input tray


200


is positioned outboard of the output print media support surface


310


of the output tray


300


(i.e., the input print media support surface


210


is positioned a distance further from the center of the printer


100


than the output print media support surface


310


) when the input tray and the output tray are in the closed position, as shown in FIG.


2


. In one embodiment of the present invention, this is a result of the rotation of the input tray


200


to the closed position, where the input tray


200


is positioned below the output tray


300


when the trays are in the open position, as shown in FIG.


1


. However, it is noted that in other embodiments of the present invention, the output print media support surface


310


of the output tray


300


could be positioned outboard of the input print media support surface


210


of the input tray


200


when the input tray


200


and the output tray


300


are in a closed position. This could be the case, by way of example, when the input tray


200


is positioned above the output tray


300


when the trays are in the open position.




As can be seen from

FIG. 2

, the input tray


200


of the first embodiment forms part of an exterior side of the printer when the input tray


200


and the output tray


300


are in the closed position. In this embodiment, the input tray


200


is substantially contoured with the housing


400


of the printer when the trays are in the closed position, thus resulting in a printer


100


of a reduced footprint as well as a printer with a uniform appearance in that the trays generally conform to the overall shape of side of the printer.




By “substantially contoured,” it is meant that the exterior (as in reference to trays in the closed position) side surface


250


of the input tray


200


, as shown in FIG.


2


and

FIG. 13

, is contoured in about the same manner as the exterior surface


410


and/or


420


of the side of the printer housing


400


into which/out of which the trays rotate, and that when the trays are in the closed position, the exterior side surface of the input tray


200


is about aligned with the surface


410


and/or


420


of the side of the printer housing


400


. Thus, there is minimal protrusion and/or intrusion of the input tray


200


from the printer housing


400


when the trays are in the closed position. However, a limited amount of protrusion/intrusion can be present in the embodiments and still obtain a substantially contoured configuration. In some embodiments of the present invention, the exterior side surface


250


of the input tray


200


protrudes about 4 mm from the exterior surface


410


and/or


420


of the printer housing. Still further, a limited amount of difference between the contours of the exterior surface


250


of the input tray and the surface


410


of the printer housing


400


can be present in the embodiments and still obtain a substantially contoured configuration. That is, the trays do not need to have the exact same contour as the contour of the exterior surface


410


/


420


of the printer housing, providing that the trays maintain a uniform finished look that is comparable to the context of at least one of the exterior surfaces of the printer housing


400


. Still further by way of example there could be a prominent protrusion or indentation on one or more of the trays to, by way of example, to notify a user as to how to open or close the trays.




It is further noted that in the above explanation of the configuration of the side of the housing


400


into and out of which the trays rotate, the input tray


200


is located on the outboard side of the output tray


300


. However, it is noted that the above explanation is applicable in a modified form as would be readily understood to one of ordinary skill in the art to embodiments where the output tray is on the outboard side of the input tray


200


; the output tray


300


having an exterior surface that is substantially contoured with the surface


410


and/or


420


of the printer housing


400


.




According to another embodiment of the present invention, the output tray


300


nests inside the input tray


200


(or visa-versa) when the input tray


200


and the output tray


200


are in a closed position. In such an embodiment, the printer


100


can utilizes a full input tray


200


including a print media support surface


210


, and an output tray


300


with a support surface


310


. It is noted that in some embodiments of the invention, the output tray


300


is not a full output tray as described above. It could include trays formed from a stub that only supports a small portion of the surface area of print media, where, in the case of an input tray positioned below the output fray, at least some of the unsupported portions of output media (e.g. portions not in contact with the stub) could come into contact with the input media supported by the input tray.




It is noted that in other embodiments of the present invention utilizing an input tray


200


and an output tray


300


that nests in the input tray


200


in the closed position, the output tray


300


is a full output tray


300


as described above. Again, it is noted that in other embodiments of the invention, the input tray


200


could nest in the output tray


300


.




It is noted that other embodiments of the present invention can utilize a full output tray


300


that nests in a full input tray


200


when the output tray is in the closed position, and visa-versa.




By the term “nest,” it is meant that at least a portion of one tray is seated inside at least a portion of another tray, as shown, by way of example, in FIG.


3


and/or in FIG.


11


.

FIG. 3

(showing the output tray


300


with output stops


330


removed for clarity and with the printer housing


400


removed for clarity) shows the configuration of the input tray


200


and an output tray


300


in the closed position. Support walls


290


extending from the input media support surface


210


extend past the output print media support surface


310


. In the embodiment shown in

FIG. 3

, when looking down an axis of rotation


335


of the output tray


300


(discussed in greater detail below) a substantial portion of the output print media support surface


310


lies inside the sidewalls


290


of the input tray.




In other embodiments of the present invention, a substantial portion of the support surface


310


of the output tray


300


lies inside an extrapolated volume formed by the input print media support surface


210


of the input tray


200


and the support walls


290


of the input tray


200


. By “extrapolated volume,” it is meant an estimated volume that would be present if the ends of the support walls


290


on either side of the input tray


200


were connected by walls running about normal to both the support walls


290


and the input print media support surface


210


of the input tray


200


, as shown by the dashed lines


2000


in FIG.


3


. From

FIG. 3

, it can be seen that the output print media support surface


310


lies inside this extrapolated volume. It is noted that in other embodiments of the invention, the output print media support surface


310


can lie outside the extrapolated volume and the output tray would still be considered nested in the input tray if a substantial portion of the output tray


300


was positioned inside the extrapolated volume.




It is noted that the trays nest even though one portion of a tray extends past another portion of the tray, as seen, by way of example, in

FIGS. 3 and 13

, where a hinged portion


3010


of the output tray (discussed in greater detail below), extends through the input tray


200


when in the closed position.




Having explained some of the possible relationships between the input tray


200


and the output tray


300


of the present invention, additional features that can be present in some embodiments will now be discussed. It is noted that some or all of these additional features described below can be practiced with some or all of the embodiments of the present invention, as is the case with some or all of the above discussed features.




In one embodiment of the invention, when the input tray


200


and the output tray


300


are in the open position, the print media support surfaces


210


and


310


can be about 20 mm from each other; surface


210


being below surface


310


. However, other embodiments of the present invention can have smaller distances or greater distances. By way of example, if 500 sheets of 8½×11 inch paper is desired to be placed in the input tray


200


, the distance between the two surfaces could be larger.




As can be seen from

FIG. 2

, the printer


100


has a cavity


600


. Cavity


600


permits the user to place his or her fingers in the cavity to impart an outward force (away from the printer


100


and with a component orthogonal to the surface


250


) on the input tray


200


and/or the output tray


300


, thus causing the trays to rotate towards the open position. It is noted that such a cavity can be present, or a variation or a plurality of variations of such a cavity can be present in the printer


100


of the present invention and still have an input tray


200


that is substantially contoured with the surface


410


of the side of the printer housing


400


.




In one embodiment of the invention, shown in

FIG. 3

, an axis of rotation


335


of the output tray


300


is defined by rotation bosses


340


extending from the sides of the output tray


300


. These rotation bosses


340


can be made as one piece with the main body


305


of the output tray


300


and can extend from the sides of the output tray


300


.




The rotation bosses


340


of the output tray


300


can fit into boss holes


420


(only one of which is shown in

FIG. 4

, which shows the housing


400


with the input tray


200


and the output tray


300


removed for clarity.) Thus, when the rotation bosses


340


are inserted into boss holes


420


, the output tray


300


can rotate from the closed position to the open position and visa-versa.




To facilitate insertion of the rotation bosses


340


into the rotation boss holes


420


, the output tray


300


can be provided with relief sections (not shown) behind one or more of the rotation bosses


340


that permit a respective rotation boss


340


to flex inward relative to the main body


305


of the output tray


300


. In one embodiment of the present invention, these relief sections comprise sections that form an exaggerated “U” shape in the main body


305


of the output tray


300


, where at least one of the legs of the “U” can be compressed towards the other leg.




In some embodiments of the present invention, the input tray


200


is of one-piece construction and is, by way of example, molded from plastic. However, other embodiments can utilize an input tray


200


that is of two or more piece construction.





FIG. 5

, which illustrates the input tray


200


without the output tray


300


, shows that in some embodiments of the present invention, an axis of rotation


230


of the input tray


200


is defined by rotation bosses


240


extending from the sides of the input tray


220


, and can extend from the gussets


220


. These rotation bosses


240


can be made as one piece with the input tray


200


and can extend from the sides of the input tray


200


.




In the first embodiment of the invention, the rotation bosses


240


of the input tray fit into boss holes


430


(only one of which is shown in FIG.


4


). Thus, when the rotation bosses


240


are inserted into boss holes


430


, the input tray


200


can rotate from a closed position to an open position and visa-versa. As with the output tray, to facilitate insertion of the rotation bosses


240


into the rotation boss holes


430


, the input tray


200


could also be provided with relief sections (not shown.) Alternatively or in addition to this, the input tray


200


could also flex. (This is the case with the output tray


300


as well.)




Some embodiments of the present invention utilize an input tray


200


that comprises a slotted gusset


220


on one or more sides of the input tray


200


which extend on a plane normal to the axis of rotation


230


of the input tray. These slotted gussets


220


can provide additional strength and flexural rigidity to the input tray


200


.




In an embodiment of the invention, one or more of the slotted gussets


220


have a detent rib


270


extending from the gussets


220


. In an embodiment of the invention, the detent rib


270


extends away from the input tray


200


from the side of the gusset


220


in the direction of the axis of rotation


230


. In other embodiments, the detent rib


270


could extend inward and/or could extend normal to the axis of rotation


230


.




The detent rib


270


can be used to lock the input tray


220


in the closed position, where “lock” is defined as providing a configuration where the input tray


200


will not move from the closed position except as a result of a force in excess of a force imparted on the mass of the input tray


200


as a result of gravity and/or the force imparted by other components of the printer


100


. That is, by way of exemplary scenario, the input tray


200


would not rotate or at least not substantially rotate from the closed position in the open direction unless a user imparted an opening force on the input tray (either directly or indirectly) sufficient to move the input tray


200


in a direction towards the open position.




In one embodiment of the present invention, this locking is obtained by alternating interference of the detent rib


270


with a rib


440


on the printer housing


400


during rotation of the input tray


200


to or from the closed position, where “interference” is defined as a state of the material where elastic or substantial elastic deformation with minor plastic deformation has occurred in either the input tray


200


or the printer housing


400


as a result of contact between the detent rib


270


and the rib


440


of the printer housing, the contact being the result of the desire (due to elastic memory of a material) of either the detent rib


270


and/or the rib


440


to occupy the same space at the same time due to the configuration of the printer


100


. By way of exemplary embodiment, when the input tray


200


is rotated in the direction of opening and/or closing, the interference could be a result of elastic deformation in at least one of the gusset


220


and a portion of the printer housing


400


that supports the rib on the printer housing.




In some embodiments of the present invention, the printer housing


400


includes one or more guide components


450


that interfere (consistent with the definition above) with one or more of the gussets


220


when the input tray is rotated in the closed and/or opened direction to plastically deform one or more of the gussets


220


and/or one or more of the components of the housing


400


so that one or more of the detent ribs


270


is pushed below (discussed in greater detail below) the rib


440


on the printer housing


400


to lock the input tray


200


in the closed position. That is, the guide component


450


can aid in the elastic deformation of the gussets


220


to enhance the locking of the input tray


200


. In some embodiments of the invention, the guide components


450


limit the elastic deformation of the gussets


220


; the bulk of the elastic deformation occurring in the components of the printer housing


400


. In other embodiments, the guide components


450


modify the deformation of the gussets


220


(e.g. increase the deformation).




In an embodiment of the invention, one or more guide components


450


are part of a spacer


460


that extend across or substantially across the cavity into which the trays close.

FIG. 6

shows the spacer


460


according to one exemplary embodiment of the present invention as seen when looking downward in relationship to the input tray


300


and the output tray


200


(with the gussets


220


) in the closed position.




The function of one embodiment of the present invention as it relates to the detent rib


270


and the rib


440


during opening and closing will now be discussed by way of exemplary scenario. Starting from the closed position of the input tray


200


of the embodiment shown in

FIG. 5

, the detent rib


270


is positioned below the rib


440


. In this configuration of one embodiment of the invention, the input tray


200


would not be able to rotate in the open direction without an exterior force being applied to the input tray


200


, as the canted end


274


of the detent rib


270


would be contacting the rib


440


and the material properties of these components would be such that they would not deform a significant amount to permit anything more than minor rotation of the input tray


200


. Owing to the ability of at least one of the components of the tray


200


and the printer housing


400


to elastically or substantially elastically deform, one or both of the rib


440


and the detent rib


270


is pushed out of the way of the other as a significant rotating force is applied to the input tray


200


, thus creating an interference between the rib


440


and the detent rib


270


. While this interference continues, the input tray


200


is inhibited and/or prevented from substantially rotating towards the open position due to the friction forces between the rib


440


and the detent rib


270


. Once the detent rib


270


clears the rib


440


so that there is no longer interference between the two components, the input tray


200


is free to rotate to the open position. In some embodiments of the invention, canted end


272


of detent rib


270


remains in contact with the rib


440


to inhibit rotation in the closed direction.




One or more of the gussets


220


of the present invention can have a slot


260


. The slots


260


of one embodiment form a semi-circle with a center point substantially aligned with the axis of rotation


230


. However, other embodiments of the present invention can utilize slots


260


of other shapes, such as by way of example, a rectangular shape, a triangular shape, an oval shape, etc. This is because in some embodiments of the invention, the slots


260


are for providing clearance for the rotation boss


340


of the output tray and/or for providing a rotation stop for the input tray


200


, as can be seen in FIG.


3


. That is, in some embodiments of the present invention, where the axis of rotation


335


of the output tray passes through the gussets


220


of the input tray


200


, the gussets


220


can surround the rotation bosses


340


of the output tray


300


. In such configurations, one or both ends


262


and


264


of the slots


260


can contact the rotation bosses of


340


when the input tray


200


is in the open position or in the closed position, respectively, thus preventing further rotation of the input tray


200


. Thus, in some embodiments of the invention, the slots


260


can be of substantially any shape or configuration providing that the slots allow for clearance of the rotation boss


340


of the output tray


200


with respect to the flanges


220


and/or provide structure that serves to limit rotation of the input tray


200


.




As can be apparent from the above discussion, in embodiments of the invention where the end


262


of the slots


260


contact the rotation boss


340


of the output tray


300


, this contact can be used to define the open position of the input tray


200


and/or the angle of the input tray


200


relative to the rest of the printer when the input tray


200


is at the open position.




In an embodiment of the invention, the input tray


200


can be provided with one or more rotation stops


280


that contact the output tray


300


when the input tray


200


is in the open position to limit the rotation of the output tray and/or define the angle of the output tray


300


at the open position when the input tray


200


is in the open position. By way of example, when the input tray


200


is at the open position, the output tray


300


, which could be rotated to its open position with the input tray


200


, could come to rest on the ends


282


of the rotation stops


280


. Rotation stop surfaces


350


could be provided on the output tray


300


that, in an exemplary embodiment, extends from the side of the output tray


300


, around which could be provided open space so that when the input tray


200


and the output tray


300


are rotated in the closed position, the ends


282


of the rotation stops


280


slide from the stop surfaces


350


and/or from contacting the stop surfaces


350


, thus permitting the output tray


300


to be nested in the input tray and/or to permit the output tray


300


to be positioned inboard of the input tray


200
