Abstract
The invention is directed to a media tray for an imaging apparatus for receiving a sheet of media. The media tray includes a base having a first side region and a second side region, a first sheet support member, a second sheet support member, a first mechanism, a second mechanism, and a force applying mechanism. The first and second mechanisms pivotally couple the first and second sheet support members to the side regions of the base, respectively. The force applying mechanism applies a force on the first and second sheet support members such that each of the first and second sheet support members diverge upwardly and outwardly from the base. The force applying mechanism includes a first cam member or first spring mechanism positioned between the first sheet support member and the base and a second cam member or second spring mechanism positioned between the second sheet support member and the base.
Description
TECHNICAL FIELD OF INVENTION
The present invention relates to a media exit or output tray for an imaging apparatus, and more particularly, to a retractable media exit or output tray for an ink jet printer.
BACKGROUND OF THE INVENTION
Most ink jet printers include some method of providing for a tray or bin to hold media once the media exits the printer. Early trays consisted of a flat tray that held the media in a flat fashion. The printing speed of early printers was slow enough so as to allow for the ink on a printed sheet of media to dry before the next sheet of media was positioned on top of the previous sheet.
As printing speeds increased, the ink on a printed sheet of media was unable to dry before the next sheet of media was positioned on top of the previous sheet. Hence, the ink would often smudge due to the contact with the next sheet of media. Some attempts have been made to address this problem by adjusting the drying properties of the ink. Other attempts have focused on methods of processing the media. For example, several printers have elaborate devices that tilt and kick the media onto staging platforms that are later actuated to allow the media to drop onto the surface of the tray. Other attempts have been directed to mechanisms which actively or passively hold the media such that the media's transverse cross section is concave.
Although the aforementioned attempts have addressed ink smudging problems with various degrees of success, they typically require complex, non-compact mechanisms or special media. Furthermore, the complexity of the mechanisms lend themselves to a higher probability of breakdown and higher costs. Also, the size of the mechanisms consume valuable desk space and are cumbersome to use. Thus, a need exists for a media exit tray with a simple design that addresses the ink drying problem, and is retractable within the printer to reduce the space required for the printer.
SUMMARY OF THE INVENTION
The invention is directed to a media tray for an imaging apparatus for receiving a sheet of media. The media tray includes a base having a first side region and a second side region, a first sheet support member, a second sheet support member, a first mechanism, a second mechanism, and a force applying mechanism. The first and second mechanisms pivotally couple the first and second sheet support members to the side regions of the base, respectively. The force applying mechanism applies a force on the first and second sheet support members such that each of the first and second sheet support members diverge upwardly and outwardly from the base. The force applying mechanism can be either a cam or spring mechanism.
In one preferred embodiment, a media tray for receiving a sheet of media transported thereto from an imaging apparatus includes a base and a media support assembly. The media support assembly is moveably coupled to the base and includes at least one cam member that engages an inclined region of the base. The at least one cam member forces an outer portion of said media support assembly to move upwardly relative to the base when the media support assembly is moved in a first direction relative to the base. The base is slideably coupled to the imaging apparatus.
The media support assembly includes a base extension having a first side region and a second side region positioned above the base. The base extension is slideably coupled to the base. The media support assembly also includes a first and second sheet support member, each of which is pivotally coupled to the first and second side regions of the base extension, respectively. Each of the first and second sheet support members includes a downwardly extending cam member having a cam surface for engaging the inclined region of the base. As the base extension is slid outward from the base, the first and second cam surfaces engage the inclined region of the base to force each of the first and second sheet support members to pivot upward and away from the base.
Other features and advantages of the invention may be determined from the drawings and the detailed description of the invention that follows. Corresponding reference characters indicate corresponding elements throughout the several figures.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1-3
show an ink jet printer
100
incorporating an exit tray
102
of the present invention. Printer
100
further includes a housing
104
and a bottom frame member
106
. As shown in
FIG. 1
, exit tray
102
is positioned in a retracted position when the printer
100
is not in use. As shown in
FIG. 2
, exit tray
102
is positioned in an extended position to receive print media, such as one or more sheets of paper, during a printing operation.
FIG. 3
shows printer
100
of
FIGS. 1 and 2
with bottom frame member
106
detached from housing
104
and exit tray
102
in the extended position.
Exit tray
102
includes a base
108
, a base extension
110
, a first sheet support member
112
, and a second sheet support member
114
. With reference to
FIGS. 1-11
, the structure and function of exit tray
102
will be discussed in greater detail.
Referring now to
FIG. 3
, base
108
is slideably coupled to bottom frame member
106
. Bottom frame member
106
includes two L-shaped guides
146
,
148
which slideably engage two corresponding base L-shaped guides (not shown) of base
108
to form a translational joint. Frame guides
146
,
148
extend from an upward-facing frame surface
150
and are located in a central, recessed portion
144
of bottom frame member
106
. Base
108
slides in a generally horizontal plane relative to bottom frame member
106
. Base
108
is slid into frame recessed portion
144
when exit tray
102
is in the retracted position and is extended from frame recessed portion
144
when exit tray
102
is in the extended position. Alternative methods could be used to couple base
108
to bottom frame member
106
, such as for example, a roller-track assembly, so long as the coupling means allows base
108
to move along a linear axis in a plane generally parallel to the plane of bottom frame member
106
.
As shown in
FIG. 4
, base
108
further includes two L-shaped guide channels
156
,
158
which slideably receive corresponding L-shaped guides
160
,
162
of base extension
110
(see FIG.
5
). Base guide channels
156
,
158
are located within a transversely centered base recess portion
152
generally below an upper surface
154
of base
108
. Base extension
110
is disposed generally within base recess
152
when exit tray
102
is in the retracted position and is extended outwardly from base recess
152
when exit tray
102
is in the extended position. Alternative methods could be used to couple base extension
110
to base
108
, such as for example, a roller-track assembly, so long as the coupling means allows base extension
110
to move along a linear axis in a plane substantially parallel to the plane of base
108
.
Base
108
further includes in base recess portion
152
two detent members
164
,
166
to impede the initial extension of base extension
110
relative to base
108
. Detent members
164
,
166
engage two detent grooves
168
,
170
in extension guide channels
160
,
162
. Detent members
164
,
166
are shown as flexible cantilever arms which snap into detent grooves
168
,
170
when base extension
110
is disposed within base recess portion
152
. Alternative structure could be employed to impede the initial movement of base extension
110
relative to base
108
, such as for example, a raised bump portion on base extension
110
which engages a recessed divot portion on base
108
.
As shown in
FIG. 5
, base extension
110
further includes a first pair of slotted apertures
186
, a second pair of slotted apertures
188
, a third pair of slotted apertures
190
and a fourth pair of slotted apertures
192
. The slotted aperture pairs are used to pivotally couple first sheet support member
112
and second sheet support member
114
to base extension
110
.
Referring to
FIG. 6
, first sheet support member
112
includes two clip pairs
198
,
200
extending from a surface
202
in a region near a proximal end
210
. Clips
198
,
200
engage the two clip receiving aperture pairs
186
,
188
formed in extension surface
180
of base extension
110
to form a rotational joint. Clip
198
includes a left and a right, partially cylindrical members
199
,
201
whose cylindrical axes are aligned to each other. Clip
200
includes a left and a right, partially cylindrical members
203
,
205
whose cylindrical axes are aligned to each other. The aligned cylindrical axes of clips
198
,
200
define a pivot axis (P
1
) of first sheet support member
112
. Alternative methods could be adopted to pivotally couple first sheet support member
112
to base extension
110
, such as for example, a standard hinge.
Second sheet support member
114
has two clips (not shown) which engage the two clip receiving aperture pairs
190
,
192
formed in extension surface
180
of base extension
110
. The structure and function of the clips of second sheet support member
114
are identical to clips
198
,
200
of first sheet support member
112
. It should be noted that second sheet support member
114
is generally a mirror image of first sheet support member
112
. Therefore, all structure and function disclosed herein for first sheet support member
112
should be understood to be applicable to the structure and function of second sheet support member
114
, unless otherwise stated.
When exit tray
102
is in the retracted position (see FIG.
1
), the upper surface
230
of first sheet support member
112
, the upper surface
232
of second sheet support member
114
and the upper surface
184
of a raised, central portion
182
of base extension
110
are generally co-planer. When exit tray
102
is in the extended position (see FIG.
2
), a distal end
208
of first sheet support member
112
and a distal end
212
of second sheet support member
114
are raised upward relative to extension surface
184
and the proximal ends
210
,
214
of first and second sheet support members
112
,
114
, respectively. The proximal ends
210
,
214
of sheet support members
112
,
114
are pivotally coupled to base extension
110
as described above and remain adjacent to base extension
110
.
Referring to
FIG. 6
, in one embodiment of the present invention, (also referred to as the cam embodiment), the upward movement of distal ends
208
,
212
of sheet support members
112
,
114
is caused because first sheet support member
112
and second sheet support member
114
each further include a downwardly extending cam member
204
which engages upper surface
154
of base
108
. Cam member
204
includes a cam surface
206
. When exit tray
102
is in the retracted position, cam members
204
of sheet support members
112
,
114
are each disposed within a cam recess
172
,
174
, respectively, located in base
108
(see FIG.
4
). Each cam recess
172
,
174
has a tapered surface
176
,
178
, respectively, which extends downwardly from base upper surface
154
. When exit tray
102
is in the extended position, cam members
204
of first and second sheet support members
112
,
114
are disposed forward of cam recesses
172
,
174
and cam member surfaces
206
rest upon base upper surface
154
.
Referring to
FIG. 7
, in another embodiment of the present invention (also referred to as the spring embodiment), cams
204
are replaced by downwardly extending leaf springs
226
. Accordingly, the upward movement of distal ends
208
,
212
of first sheet support member
112
and second sheet support member
114
results from an upward force generated by leaf springs
226
. When exit tray
102
is in the retracted position, leaf springs
226
are compressed generally against sheet support members
112
,
114
and against base upper surface
154
. Since leaf springs
226
flex, base cam recesses
172
,
174
are not required in base
108
. In the retracted position, a downwardly facing surface
228
of frame member
106
applies a downward force on the upper surfaces
230
,
232
of first and second sheet support members
112
,
114
. When exit tray
102
is in the extended position, first and second sheet support members
112
,
114
are forward of frame surface
228
and the compression of leaf springs
226
is relieved to thereby lift distal ends
208
,
212
of sheet support members
112
,
114
.
The interaction between the various components in the embodiments of exit tray
102
will now be explained through a discussion of: (a) the relationship between the components in the retracted position, (b) as the components are moved from the retracted position to the extended position, (c) components in the extended position, and (d) as the components are moved from the extended position to the retracted position.
When the cam embodiment of the present invention is in the retracted position (see FIG.
1
); base
108
, base extension
110
, first sheet support member
112
and second sheet support member
114
are generally within the recessed portion
144
of bottom frame member
106
(see FIG.
3
). Base extension
110
, first sheet support member
112
and second sheet support member
114
are generally co-planar relative to each other and disposed generally above base
108
such that base extension detent grooves
168
,
170
(see
FIG. 5
) engage base detent members
164
,
166
(see FIG.
4
), and such that cam members
204
are within base cam recesses
172
,
174
.
The cam embodiment of exit tray
102
is moved from the retracted position (see
FIG. 1
) to the extended position (see
FIG. 2
) by the application of an outward force by a user on a grip surface
196
of a grip portion
194
of base extension
110
. Initially base
108
, base extension
110
, sheet support members
112
,
114
all move outward together. This is because detent members
164
,
166
(see
FIG. 4
) have a larger force threshold than the translational joint between base
108
and bottom frame
106
. Once base
108
is fully extended, the force threshold of detent members
164
,
166
is overcome and base extension
110
slides relatively outward or forward from base
108
. As base extension
110
slides outward relative to base
108
, cam surface
206
(see
FIG. 6
) of first sheet support member
112
travels up base cam surface
176
(see
FIG. 2
) thereby forcing first sheet support member
112
to rotate at clips
198
,
200
such that distal end
208
of right sheet support member
112
is raised relative to proximal end
210
. The distal end
212
of the second sheet support member
114
is raised relative to proximal end
214
by identical means.
Once the cam embodiment of exit tray
102
is in the extended position (see FIG.
2
), cams
204
are forward of base cam recesses
172
,
174
and each cam surface
206
of cams
204
of sheet support members
112
,
114
rests on base upper surface
154
. Base
108
may be held in the extended position, for example, by positioning detent members on bottom frame member
106
to engage base
108
.
The cam embodiment of exit tray
102
is moved from the extended position to the retracted position by the application of an inward force by the user on grip
194
to force base extension
110
, first sheet support member
112
and second sheet support member
114
to slide inward relative to base
108
. As the sheet support members
112
,
114
slide inward, cam surfaces
206
of cams
204
slide back down tapered surfaces
176
,
178
and into base cam recesses
172
,
174
(see FIG.
2
). As cam surfaces
206
slide down tapered surfaces
176
,
178
, distal ends
208
,
212
of sheet support members
112
,
114
rotate downward until they are generally co-planar with base extension
110
. Once base extension
110
detent grooves
168
,
170
(see
FIG. 5
) engage base detent members
164
,
166
(FIG.
4
), base extension
110
is fully retracted and first and second sheet support members
112
,
114
are generally co-planar with base extension
110
. Base
108
then slides into the bottom frame recess portion
144
of bottom frame member
106
, and below downward-facing surface
228
of housing
104
.
The spring embodiment of the present invention is substantially identical to the cam embodiment. The most important difference between the spring and cam embodiments is the replacement of cam members
204
(see
FIG. 6
) with leaf springs
226
(see FIG.
7
). When the spring embodiment of exit tray
102
is in the retracted position, downward-facing surface
228
of frame member
106
applies a downward force on the upper surfaces
230
,
232
of first and second sheet support members
112
,
114
, thereby maintaining leaf springs
226
in a compressed state.
In the spring embodiment, as exit tray
102
is moved from the retracted position toward the extended position, sheet support member upper surfaces
230
,
232
begin to clear frame surface
228
and the distal ends
208
,
212
of first and second sheet support members
112
,
114
rotate upward due to the upward force generated as leaf springs
226
are relieved from their compressed state.
As exit tray
102
is moved from the extended position to the retracted position, a downward force is applied to the upper surfaces
230
,
232
of first and second sheet support members
112
,
114
so that upper surfaces
230
,
232
pass beneath frame surface
228
. This downward force can be achieved manually, for example, by the user applying the downward force. The downward force can also be applied by frame surface
228
by selecting a shape of support members
112
,
114
or frame surface
228
such that contact of the upper surfaces
230
,
232
with frame surface
228
occurs progressively from proximal ends
210
,
214
to distal ends
208
,
212
of sheet support members
112
,
114
as exit tray
102
is moved toward the retracted position. It is within the scope of the present invention to have shallow recesses in base
108
, generally similar to cam recesses
172
,
174
to accept leaf springs
226
to reduce the downward force to be applied to upper surfaces
230
,
232
when exit tray
102
is moved from the extended position to the retracted position.
FIG. 8
shows a diagrammatic side view of the operation of ink jet printer
100
with the cam embodiment of exit tray
102
.
FIG. 9
shows a diagrammatic side view of the operation of ink jet printer
100
with the spring embodiment of exit tray
102
. Structural components common to
FIGS. 8 and 9
are referred by corresponding reference numerals. Unless otherwise indicated, the discussion that follows applies to both
FIGS. 8 and 9
.
A sheet of media
116
is transported from an input tray
118
to exit tray
102
by a series of rollers
120
,
122
, and
124
. As media
116
is being transported, it passes beneath a printhead assembly including a cartridge
126
and a carrier
128
. The cartridge
126
is removably secured to carrier
128
by a spring-loaded latch (not shown). Carrier
128
is reciprocated back and forth along a guide rod
130
by a drive belt (not shown). The drive belt is driven by a motor that is controlled by an electronic control means. The bottom of carrier
128
contains a foot
132
which rides in a groove
134
of guide rail
136
. Both guide rail
136
and guide rod
130
are secured to the side frames (not shown) of printer
100
. A nozzle plate
138
on the bottom of a downwardly extending portion
140
of cartridge
126
contains an array of nozzles (not shown) for ejecting ink droplets in a downward direction, toward media
116
. A trough
142
is provided to collect waste ink droplets.
As media
116
passes beneath nozzle plate
138
, nozzle plate
138
along with the rest of the printhead assembly is reciprocated back and forth along guide rod
130
. Ink is ejected from the nozzles in nozzle plate
138
at prescribed transverse locations, to form an image on media
116
. The transverse cross-section of media
116
is generally linear while it is being carried from input tray
118
to exit tray
102
.
FIG. 10
shows exit tray
102
in the extended position receiving a sheet of media
116
exiting printer
100
. As media
116
begins to exit printer
100
, the media bends downwardly until media
116
is supported at its right edge
220
by a region of surface
230
near distal end
208
of first sheet support member
112
and at its left edge
222
by a region of surface
232
near distal end
212
of second sheet support member
114
. As long as the trailing end of media
116
is supported within printer
100
, and supported at right and left edges
220
,
222
by sheet support members
112
,
114
, media
116
is held generally flat (planar), but with a slight undulation which increases in magnitude from the trailing end of media
116
to the front end of media
116
. Once the trailing end of media
116
is released by printer
100
, media
116
assumes a generally concave shape along its transverse direction due to the support of right and left edges
220
,
222
and the downward force of gravity on the unsupported regions of media
116
. The central portion of media
116
rests on upper surface
184
of base extension
110
. The concave, transverse cross-section provides increased stiffness to media
116
along its longitudinal axis. Because of the increased stiffness, media
116
can have a longer longitudinal extent than the extent of exit tray
102
in the extended position and still maintain a linear longitudinal cross-section.
Since the printed media is retained in exit tray
102
