- media tray 124 provides a tray capable of accommodating differently sized media. To accommodate shorter media, media guide 130 is unlocked and moved towards end wall 142 . To accommodate longer media, media guide 130 is unlocked and moved away from end wall 142 . To accommodate media having a dimension greater than the dimension of tray portion 126 , media guide 130 is moved away from end wall 142 which results in end wall 168 and tray portion 128 also moving away from end wall 142 . As a result, media guide 130 may be distended from end wall 142 by an even larger distance to accommodate even larger media. This enhanced capability of tray 124 to accommodate different media sizes is achieved with relatively few and inexpensive components.

As a result, movement ofrack gear 220 and media guide 130 through a first distance alongaxis 154 results intray portion 128 moving alongrack gear 226 and alongaxis 154 through a second greater distance. In one embodiment, gears 232 and 234 have a gear ratio of about 1.6. In other embodiments, gears 232 and 234 may have other gear ratios,gear 232 may have a larger diameter as compared togear 234 or gears 232 and 234 may have a common diameter. - Stop 236 comprises a structure configured to hinder rotation of
cluster gear 228 to inhibit or prevent the relative movement oftray portions basin 160. Stop 236 comprises a D-shaped structure having a flat 250.Flat 250 is configured to interact or abut flat 224 and to allow flat 224 to slide along and relative to flat 250 when media guide 130 is to be moved relative totray portions tray portion 128 relative totray portion 126. During such abutting engagement of flat 250 with flat 224, flat 250 further inhibits or preventstray portions - In other embodiments,
transmission 134 may have other gear arrangements or other mechanisms for transmitting power or motion resulting from the movement of media guide 130 to one or both oftray portions tray portions cluster gear 228 may alternatively be rotatably coupled totray portion 126 andrack gear 226 may alternatively be coupled totray portion 128. In other embodiments, other mechanisms may be utilized to lock or otherwise retaintray portion 126 relative totray portion 128 in lieu ofstop 236. For example, in other embodiments, flat 224 may alternatively be provided adjacent to rackgear 226 in lieu of adjacent to rackgear 220. -
FIGS. 10-15 illustrate the operation oftray 124.FIGS. 10 and 11 illustratetray portion 128 and media guide 130 in their most extended position relative to endwall 142 oftray portion 126, allowingtray 124 to receive one or more sheets of media having a long dimension alongaxis 154. As shown byFIGS. 10 and 11 , whentray portion 128 and media guide 130 are in their extended most positions, media guide 130 is in abutment withend wall 168 oftray portion 128. As a result, media guide 130 cannot be moved further to the left as seen inFIG. 10 and clockwise rotation ofcluster gear 228 alongrack gear 226 is prevented to preventtray portion 128 from being further extended away fromtray portion 126. -
FIGS. 12-14 illustratetray portion 128 in a fully retracted position relative totray portion 126. In particular,FIGS. 12-14 illustratetray 124 after media guide 130 has been manually moved to the right as seen inFIG. 12 fromadjacent end wall 168 toward end wall 142 (shown inFIG. 3 ). During such movement of media guide 130,rack gear 220 is moved againstgear 232 which results incluster gear 228 rotating in a counterclockwise direction as seen inFIG. 12 . The counterclockwise direction ofgear 228 againstrack gear 226 results intray portion 128 also moving to the right as seen inFIG. 12 towards end wall 142 (shown inFIG. 3 ). As noted above, due to the ratio betweengears tray portion 128,tray portion 128 moves a corresponding greater incremental distance. Such movement oftray portion 128 in response to movement of media guide 130 continues as media guide 130 is moved to the right as seen inFIG. 12 untilgear 232 disengages rackgear 220 and flat 250 abuts flat 224. - As shown by
FIGS. 13 and 14 , abutment of flat 250 with flat 224 prohibits rotation ofcluster gear 228 during further movement of media guide 130 to the right as seen inFIG. 12 . At the same time, flat 224 is permitted to slide relative to flat 250, allowing further movement of media guide 130 to the right relative totray portions tray portion 128 relative totray portion 126. As a result, even whentray portion 126 is in its most retracted position relative totray portion 126 andend wall 142, media guide 130 may still be moved into close proximity withend wall 142 to accommodate media having even smaller dimensions alongaxis 154. -
FIGS. 15 and 16 illustrate media guide 130 moved to its most retracted position relative to end wall 142 (shown inFIG. 3 ). In the particular example illustrated, further movement of media guide 130 to the right as seen inFIG. 15 is prevented by abutment ofend 254 ofrack gear 220 with a structure associated withtray portion 126, such as an end ofchannel 149. As a result,cluster gear 228 remains in mutual engagement with flat 224 andrack gear 226, inhibiting or preventingtray portion 128 from being moved alongrack gear 226 and from being distended relative totray portion 126 while media guide 130 is stationary or is retained in place by lockingmechanism 132. - To accommodate media having a greater dimension along
axis 154,locking mechanism 132 is released (catch 202 is moved to the disengaged position) and media guide 130 is moved to the left as seen inFIG. 15 by sliding flat 224 along flat 250 to the position shown inFIG. 12 . Should it be desired thattray 124 accommodate media having even a greater dimension alongaxis 154, media guide 130 may be further moved to the left as seen inFIG. 12 towards the position shown inFIG. 10 . During such movement of media guide 130,rack gear 220 rotatescluster gear 228 to causecluster gear 228 to rotate alongrack gear 226 to distendtray portion 128 relative totray portion 126 to allow media guide 130 to be moved even further to the left as seen inFIG. 10 . - Overall,
media tray 124 provides a tray capable of accommodating differently sized media. To accommodate shorter media, media guide 130 is unlocked and moved towardsend wall 142. To accommodate longer media, media guide 130 is unlocked and moved away fromend wall 142. To accommodate media having a dimension greater than the dimension oftray portion 126, media guide 130 is moved away fromend wall 142 which results inend wall 168 andtray portion 128 also moving away fromend wall 142. As a result, media guide 130 may be distended fromend wall 142 by an even larger distance to accommodate even larger media. This enhanced capability oftray 124 to accommodate different media sizes is achieved with relatively few and inexpensive components. - Although the present disclosure has been described with reference to example embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the claimed subject matter. For example, although different example embodiments may have been described as including one or more features providing one or more benefits, it is contemplated that the described features may be interchanged with one another or alternatively be combined with one another in the described example embodiments or in other alternative embodiments.
