Abstract
The present invention is a set-top box integrated with a low-height printer. The printer includes an input tray for storing input media sheets and an output area for holding output media sheets. The printer further includes a printhead that scans and prints on the media sheets from the front to the back of the printer. The media sheets are stored in the input tray in a landscape orientation and are held in the output area in a semi-curled position. Alternatively, the media sheets are stored in the input tray in a portrait orientation.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to printers, and more particularly, to a low profile printer integrated within a digital set-top box.
2. Related Art
Set-top boxes such as cable television boxes, Internet terminal boxes etc. are increasingly being used with consumer home entertainment equipment such as television sets. For example, most “pay for” broadcast services that use television interaction, such as cable television services and Internet access services via the television, require their users to have some type of set-top box. Note that the term “broadcast services” refers to signals being transmitted over analog telephone lines, coaxial cable lines, fiber optic lines, satellites and the like.
The set-top box typically allows the user to select between channels, perform programming functions, etc. Also, for efficient broadcast transmission and, in some cases, to ensure that only paying customers are using these services, the broadcast signals are usually scrambled or encoded before being transmitted and the set-top box decodes the signals. Consequently, television set-top boxes are becoming an integral part of home entertainment equipment.
There are many instances when a user may want a hardcopy of the information displayed on the screen of their television set. For example, a user may want to print e-mail messages, maps, recipes and information-rich content, such as still or captured scenes from a live broadcast, digital video disk (DVD) players, movie cameras, video recorders etc.
Currently, conventional printers are manually connected to the set-top box when users desire hard copies of the information displayed on the screen of their television sets. However, most conventional printers are bulky, and thus require large amounts of space in users' home entertainment units. Also, expensive and additional cables are required to connect the printer to the set-top box. Further, most conventional printers are not aesthetically appealing like entertainment equipment. This is because most printers are not designed to be used with an entertainment center, but are instead designed to be used with other office equipment. As such, most printers do not match well with other home entertainment equipment.
Thus, what is needed is a set-top box with an integrated low-height printer that will save space in home entertainment units. What is also needed is a printer that will blend in with ordinary home entertainment equipment and will not require the use of exposed and expensive printer cables.
SUMMARY OF THE INVENTION
To overcome the limitations of the systems: and methods described above, and to overcome other limitations that will become apparent upon reading and understanding the present specification, the present invention is embodied in a set-top box having an integrated printer. The printer is preferably a low-height printer and includes front and back portions, an input tray for storing input media sheets, an output area for holding output media sheets and a printhead for printing information on the media sheets. The printhead prints information on the media by sequentially scanning the printhead across the media as the media is advanced toward the output area (each scan is commonly referred to as a swath). The printer preferably accepts any standard media, such as 8.5×11 inch (letter size), 8.5×14 inch (legal size), A4, A5, etc papers.
In one embodiment, the paper is stored in the input tray in a portrait orientation so that the shortest dimension of the paper exists from the front to the back of the printer. For example, for 8.5×11 inch paper, the 8.5 inch dimension would exist from the front to the back of the printer and the 11 inch dimension would exist from one side to the other side of the printer. The paper is advanced to the output area in a portrait orientation. Thus, the printhead scans from the front to the back of the printer and each swath is printed across the shortest dimension of the paper.
In another embodiment, the paper is stored in the input tray in a landscape orientation so that the longest dimension of the paper exists from the front to the back of the printer. For example, for 8.5×11 inch paper, the 11 inch dimension would exist from the front to the back of the printer and the 8.5 inch dimension would exist from one side to the other side of the printer. The paper is advanced to the output area in a landscape orientation. Thus, the printhead scans from the front to the back of the printer and each swath is printed across the longest dimension of the paper.
As a result, in both embodiments, the printhead moves from the front to the back of the box when scanning and printing on the media sheets. Further, to reduce the side to side width of the low-height printer, the output media sheets are held in the output area in a semi-curled position. Unlike some conventional inkjet printers that use a U-shaped path, the present printer uses a straight through path from the input tray to the output holding area. This allows the height of the set-top box to be kept to a minimum.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In the following description of the preferred embodiment, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration a specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
Overview
As shown in the drawings for the purposes of illustration,
FIG. 1
depicts an overview block diagram of a home entertainment system
100
of the present invention. Namely, the system
100
includes a television set
102
and a home entertainment unit or a hybrid printer and set-top box
106
. The hybrid printer and set-top box
106
can be positioned near or on top of the television set
102
and contains a set-top box
108
, set-top box electronics
110
and a print mechanism
120
. The set-top box electronics
110
electronically connects the print mechanism
120
via any suitable manner, such as an electrical cable (not shown), to the set-top box
108
. The set-top box electronics
110
is also connected to the television set
102
via any suitable manner, such as a coaxial cable (not shown).
The set-top box electronics
110
contains at least a processor or controller (not shown) to process data. Depending on the set-top box, processing data may include decoding encoded data, processing data from the Internet and processing data that is to be printed by the print mechanism
120
. Thus, the set-top box electronics
110
may include both conventional set-top box electronics and printer electronics.
The set-top box electronics
110
can also contain a non-volatile memory (not shown) for storing software programs to run the print mechanism
120
(i.e., a printer driver) and to decode encoded data (i.e., decoding algorithm) or to access and interpret data from the Internet (i.e., a web browser). As will be explained later, the print mechanism
120
may have a partner electronics connector or electronic port to electronically couple audio/visual equipment, such as a video camera, video recorder, DVD player and the like to the hybrid printer set-top box. The partner electronics port may also be used to download needed software to the set-top box electronics
110
. That is, software upgrades as well as new software (e.g., video capture software) may be downloaded into the set-top box electronics
110
via the partner electronics port.
However, currently, for printing purposes, problems exist when a user desires a hard copy of the information displayed on the television screen. Although conventional printers can be manually connected to some set-top boxes, most conventional printers are bulky, and thus require large amounts of space in users' home entertainment units. In addition, most conventional printers do not match the decor of entertainment equipment.
The hybrid set-top box with an integrated low-height printer in accordance with the present invention solves these problems. One advantage of the present invention is that the cost of manufacturing for the hybrid set-top box and printer is reduced. Namely, the hybrid set-top box and printer shares a single, albeit slightly larger, power supply device. Ordinarily, the cost of two individual power supply devices is greater than the cost of one device. In addition, the hybrid set-top box and printer shares a common top-case material. As is well known in the industry, top-case materials are typically expensive components. Further, the hybrid set-top box and printer allows for the full integration of the printer electronics onto the set-top box electronics board. This will additionally contribute to more cost savings. Part of these manufacturing cost savings will likely be passed along to the users in the form of reduced prices for the hybrid box.
Another advantage is that the hybrid set-top box and printer can be manufactured to match the style and decor of typical home entertainment equipment. In addition, since the set-top box and printer of the present invention is an integrated hybrid device, it saves space in users' home entertainment centers.
Component Details and Operation
Landscape Print Mechanism
FIG. 2
illustrates one embodiment of the present invention, namely a print mechanism of the hybrid set-top box printer
106
of FIG.
1
. The print mechanism of
FIG. 2
is a landscape print mechanism
200
depicted by a cut-away front perspective view. The landscape print mechanism
200
includes a printhead
210
, a pick and feed roller
220
, a print bar
230
, an input tray
240
and partner electronics, preferably including an interconnection port
250
(hereinafter collectively referred to as “partner electronics/port
250
”). As previously mentioned, the partner electronics/port
250
can be used to electronically couple additional equipment to the hybrid printer and set-top box. The partner electronics/port
250
can further be used to upgrade software used to operate the set-top box. The partner electronics/port
250
may be located on either the top of the box or on any of the sides of the box. There may also be a plurality of partner electronics/ports
250
.
A plurality of media sheets
260
are stored, one atop another, in the input tray
240
. To ensure that the width of the hybrid set-top box and printer meets standard width specifications of home entertainment equipment, such as 430 mm, an output tray is preferably not used. Instead, the media sheets
260
are pushed or kicked in the output area of the hybrid set-top box and printer in the direction shown by the arrows.
In addition, to further ensure that the
430
mm width specification is met, the media sheets
260
are preferably stored in the input tray
240
in a landscape orientation so that the shortest dimension (width) of the paper exists from one side
266
to the other side
268
of the printer
200
, as shown in FIG.
2
. Hence, the media sheets
260
are also held in the input tray
240
in a landscape orientation. For example, for 8.5×11 inch paper, the 8.5 inch dimension (width) would exist from side
266
to side
268
of the printer
200
and the 11 inch dimension (length) would exist from a front
270
to a back
275
of the printer
200
.
In operation, the input tray
240
may be suitably lifted by an automatic lifter or resiliently biased against the pick and feed roller
220
by a spring to allow the pick and feed roller
220
to pick the topmost media sheet
260
from the input tray
240
. The printing process starts by actuating the pick and feed roller
220
to move the leading edge of the media sheet
260
toward the print bar
230
. The actuating mechanism is well known in the art and thus is not described. To allow the printhead
210
to print on the media sheet
260
, the sheet is stopped momentarily in a print zone (not shown).
When printing on the media sheet
260
, the printhead
210
scans the media sheet
260
on an axis from the front
270
to the back
275
of the printer
200
and the paper is advanced by the roller
220
to an output area
280
in a landscape orientation. In other words, as the printhead
210
scans from the front
270
to the back
275
of the printer
200
, each swath of ink is printed across the longest dimension of the paper. After information is printed on the media sheet
260
, the media sheet
260
is kicked or pushed into the output area
280
. The output area preferably has a curved track for holding the outputted paper in a semi-curled position for saving space.
Portrait Print Mechanism
FIGS. 4 and 5
illustrate another embodiment of the present invention.
FIGS. 4 and 5
are identical to
FIGS. 2 and 3
, respectively, with the exception of input tray
440
, which is disposed in a portrait orientation (see FIG.
5
). The configuration of
FIG. 5
allows the hybrid set-top box and printer
106
of
FIG. 1
of the present invention to have a reduced depth.
Similar to
FIGS. 2 and 3
,
FIGS. 4 and 5
show a plurality of media sheets
460
stored, one atop another, in input tray
440
of printer
400
. The media sheets
460
are pushed or kicked into output area
480
of the hybrid printer and set-top box in the direction shown by the arrows. As in the embodiment of
FIG. 2
, an output tray is not used. Instead, the media sheets
460
are held in the output area
480
in a semi-curled position. This configuration ensures that specific width specifications of home entertainment equipment is also met in this embodiment.
In operation, the input tray
440
may also be lifted to allow pick and feed roller
420
to pick the topmost media sheet
460
from the tray. Similar to printer
200
of
FIG. 2
, the printing process for printer
400
starts by actuating the pick and feed roller
420
to move the leading edge of the media sheet
460
toward the print bar
430
. To allow the printhead
410
to print on the media sheet
460
, the sheet is stopped momentarily in a print zone (not shown).
However, in this embodiment, the media sheets
460
are preferably stored in the input tray
440
in a portrait orientation so that the shortest dimension (width) of the paper exists from a front
470
to a back
475
of the printer
400
, as shown in FIG.
4
. Hence, the media sheets
460
are held in the input tray
440
in a portrait orientation. For example, for 8.5×11 inch paper, the 8.5 inch dimension (width) would exist from the front
470
to the back
475
of the printer
400
and the 11 inch dimension (length) would exist from one side
466
to the other side
468
of the printer
400
. The media sheets
460
are fed to the printbar
430
in the same portrait orientation as stored. After information is printed on the media sheet
460
, the media sheet
460
is kicked or pushed into output area
480
.
Thus, when printing on the media sheet
460
, the printhead
410
scans the media sheet
460
on an axis from the front
470
to the back
475
of the printer
400
and the paper is advanced by the roller
420
to the output area in a portrait orientation. In other words, as the printhead
410
scans from the front
470
to the back
475
of the printer
400
, each swath of ink is printed across the shortest dimension of the paper.
Media Sheet Access
In both embodiments of
FIGS. 2-5
, input media sheets are stored in respective input trays. The input trays, as will be explained later may be slid in and out of the hybrid set-top box and printer. Output media sheets may be retrieved, however, in a variety of ways. For example, the output media sheets may be retrieved through an open slot located on top of the box (see
FIG. 6
) or through an open door on top of the box (see FIG.
7
).
In
FIG. 6
, the media sheets
610
are shown semi-curled or curved over a track of output area
620
, printbar
630
and input tray
640
.
FIG. 7
shows input area
740
, printbar
730
, semi-curled media sheets
710
that are curved over a track of output area
720
and door
750
. Note that although the invention is shown having top accesses to the output media sheets, it is not restricted to only such accesses, side accesses are equally within the scope of the invention.
Print Mechanism Access
FIG. 8
illustrates consumer accesses to the print mechanism. For example, access to the printhead such as to replace ink cartridges can occur through an opening
815
behind the hybrid set-top box and printer front panel. In addition, an input paper tray
840
may be slid in and out of the set-top box through opening
845
. Openings
815
and
845
may also be used to clear paper jams. These openings can be placed at the rear as well as atop the box. Also, if the top of the box is not used to store or retrieve media sheets or to provide access to the print mechanism of the present invention, other equipment can be stacked atop the box.
Alternative Embodiments
FIG. 9A
illustrates a cut-away perspective view of the present invention with slots open atop the set-top box to store input media sheets as well as to retrieve output media sheets.
FIG. 9B
illustrates a cut-away perspective view of the present invention with door access to store and to retrieve media sheets. As shown, either side of the hybrid set-top box and printer can be used to store the output media sheets. If input media sheets are stored at side
900
, the sheets will travel from right to left. If, on the other hand, the input media sheets are stored at side
910
, the sheets will travel from left to right.
In either
FIG. 9A
or
FIG. 9B
, input and output media sheets are held in a semi-curled or curved up position. This configuration allows for an even more compact set-top box. Note that in both
FIGS. 9A and 9B
, printbar
980
is shown. Note also that open door access
920
is shown in FIG.
9
B.
Conclusion
The present invention uses a minimal number of rollers (i.e., the pick and feed roller) and does not stack the output of the printer on top of the input. Thus, the present invention uses a straight through paper path as opposed to the U-shaped paper path of conventional printers. This allows the printhead to be located only one inch above the bottom of the box. The straight through paper path and the low printhead contribute to a low profile hybrid printer and set-top box.
The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Therefore, the foregoing description should not be taken as limiting the scope of the invention defined by the appended claims.
