In the preferred embodiment illustrated, there has provided a mobile
phone having an internal printer which includes a separately detachable
printhead and ink supply module. The printer phone can be produced
at or close to a standard size phone for any system including PHS,
GSM and GPRS, thereby conferring a higher level of convenience during
operation.
Turning initially to FIG. 1, there is illustrated the preferred
embodiment 1 in the form of a PHS phone and which in many ways looks
like and includes the features of a conventional mobile phone of
this type including an ear piece 2, microphone 3, aerial 4, loud
speaker 5, a series of push buttons 6 and a preferably color LCD
screen 7 for the display of information. Also included is a battery
8 as shown in FIG. 4.
The phone 1 can optionally be equipped with a camera device 10
comprising lenses 11 and associated CCD chip or CMOS sensor 12.
The CCD or CMOS sensor enables the device to store images on demand,
so that the phone can effectively act as a camera device for the
printing out of images, or for their capture and forwarding across
a mobile phone network. The operation of the relevant part of the
internal control electronics can be substantially as set out in
the applicant's earlier PCT application WO 99/04551 entitled "A
replenishable one time use camera system" the contents of which
are incorporated herein by reference. In other embodiments, the
camera device may also be configured to enable video conferencing
by facilitating simultaneous image processing during phone transmission.
A camera function that is mounted for selective movable positioning
on the phone device may be useful for this purpose. For example,
it may be rotatable between a forward facing camera orientation
and a rearward facing video conferencing orientation.
The printer apparatus is shown generally at 15 and comprises a
printhead and ink supply module 16 including a printhead 17, an
ink supply/distribution unit 18 and a print media feed apparatus
20. The feed apparatus is of a conventional form including a motor
21 with associated gear train 22 which drive a series of feed rollers
23.
The packaging of the printer apparatus 15 is best shown in FIGS.
5, 6 and 9. In this regard the printer phone 1 is constructed around
a rigid chassis molding 25. The chassis is adapted to slideably
receive and retain the printhead and ink supply module 16 by means
of retaining flanges 26 provided on the outer casing of the printhead
module 16 which cooperate with under cut channels 27 provided on
the chassis molding.
The full operation of the printer apparatus 15 is best illustrated
in FIG. 9. In use print media 30, preferably in the form of business
card sized paper or card sheets, is fed in through an entry slot
31 provided in the external phone casing 32. This can be done manually
or via a dispenser as described hereafter. The card 30 is then picked
up by the powered entry feed rollers 23 and delivered to the printhead
module 16. The printhead and ink supply module can be substantially
the same as that disclosed in Australian Provisional Patent No.
PP6534 entitled "Micromechanical Device and Method (IJ46A)"
filed 16 Oct., 1998, the contents of which are also hereby incorporated
by cross-reference. In such a device, the printhead is in the form
of an elongate printhead chip that extends the full length of the
print media pathway, so as to print the fall width of the print
media in a single pass without the need for any printhead traversing
mechanisms.
In this particular preferred embodiment, the printhead and ink
module is formed as a sealed unit which is replaced in its totality
after a predetermined amount of usage. The detailed structure of
the ink supply and printhead module is shown more clearly in FIG.
8. The ink supply/distribution unit 18 is of a molded multi-part
structure including a cover 35, a macro channel molding 36 defining
four separate ink supply chambers 37 40 having therein optional
flow control baffles 41. Connected with converging outlets of the
macro channel molding 36 is a micro-molding 42 which defines similarly
converging ink flow nozzles 43 that accurately direct the ink to
minute ink supply inlets on the rear of the printhead 17. Optionally,
an ink filter 44 is provided between the two moldings. A capping
device 47 is also provided as part of the module for sealing and
protecting the nozzle outlets when the printer head is not in use.
It is estimated that the ink supply will on average be sufficient
for printing approximately 1000 pages at 15% coverage of black or
100 photos of 50% coverage of CMYK. An expanded technical description
of the printhead and ink supply module can be found in the aforementioned
provisional patent specification PP6534 and associated applications.
The mobile phone system can be operated under the control of a
series of one or more application specific integrated circuits (ASICS)
which incorporate the usual mobile phone capabilities in addition
to camera and image processing capabilities. An adaptation of the
system outlined in PCT Patent Application PCT/AU98/00544 filed by
the present applicant (also incorporated herein by reference) can
be utilised in the design of the ASIC. The electrical interconnections
for the preferred embodiment is shown schematically as a block diagram
in FIG. 16. Other system designs well known to those skilled in
this field may also be used.
Referring next to FIGS. 11 to 15 there is illustrated a print media
dispenser 50 configured for use with the PHS phone of the previous
embodiments. The dispenser comprises a lower molding 51 that defines
a media storage and dispensing region 52 and a cradle 53 which supports
the printer phone 1 and aligns it with the outlet of the dispenser.
The interactive operation of the print media dispenser with the
phone 1 is best illustrated in FIG. 14. As can be seen, the dispenser
50 has a storage area 52 in which is disposed a quantity of print
media in the form of business card sized paper or card sheets 54.
These cards are supported on a metal base plate 55 which is sprung
by means of opposed spring fingers 56 as shown in FIG. 15. In this
manner, the card supply is constantly biased upwardly toward a media
ejector mechanism 58. The ejector mechanism includes an ejector
slider 59 which is operable upon manual sliding against a return
spring 60 to pick up the top card and feed this out of the dispenser
outlet 61 and into the media entry slot 31 on the phone 1. On release,
the slider automatically returns to the home position to engage
the next card ready for further loading.
Desirably, the printer phone 1 and/or printhead and ink supply
module 16 includes an authentication mechanism such as that outlined
in the applicant's earlier PCT application no. PCT/AU98/00544 entitled
"A camera with an internal printing system". This can
be used to ensure not only that an authenticated approved consumable
(such as the printhead and ink supply module) is used with the printer
phone, but can also be used to store data on the relative usages
of the consumable components such as the ink or the printhead itself
and can optionally be used to set a predetermined usage for these
items.
As noted above, the phone device of the invention may be any kind
of mobile phone that sends and receives signals in a manner which
can be processed into a printable form. Further, while the preferred
form described has a printhead and ink distribution unit which has
an integrally formed and attached ink supply, the ink supply could
be separate and optionally also separately replenishable.
While the invention has been described with reference to specific
examples, it will be appreciated by those skilled in the art that
the invention may be embodied in many other forms.
