Abstract

A digital palm PC is provided which has a housing, a digital storage device to store digitally text and/or image data, and a pagewide inkjet printer located within the housing to receive digital information from the digital storage device. The printer is configured to print an image on media external thereto as the palm PC traverses the media in a printing orientation.

Description

    CROSS REFERENCE TO RELATED APPLICATION
  • This Application is a continuation application of U.S. patent application Ser. No. 11/505,858 filed on Aug. 18, 2006, which is a continuation application of U.S. patent application Ser. No. 10/503,899, filed on 9 Aug. 2004, now issued U.S. Pat. No. 7,140,792, which is a 371 of PCT/AU03/00162, filed on Feb. 12, 2003, all of which is herein incorporated by reference.
    • FIELD OF INVENTION
  • The following invention relates to a hand-held personal computer known as a “palm PC”, having a built-in printer.
    • BACKGROUND TO INVENTION
  • Known palm PCs have no means of providing an “instant” print-out of text and/or images therefrom. Instead, if a print-out is needed, the palm PC must communicate data stored therein to another PC to which there is attached a printer.
  • The mere incorporation into a palm PC of a known conventional printer device would not result in a compact, easily portable palm PC. This is because prior printers incorporate a supply of print media and employ a print media feed mechanism to transport the print media past the printheads to effect printing onto the print media. Moreover, known printers, having a supply of print media, are large and heavier than would be desirable in a portable palm PC that is sized and shaped to fit conveniently with a user's pocket or purse for example.

    • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • In FIG. 1 of the accompanying drawings there is schematically depicted a palm PC 10 having an integral printer. The palm PC is sized and shaped to fit within a typical purse or pocket user and is shown in the figure traversing a page of print media 11 to print an image 12 thereon.
  • As shown in FIG. 2, the palm PC includes a housing having a top molding 13 and a base molding 14. These moldings house the internal components of the device. The palm PC includes a color liquid crystal display (LCD) and touch screen 20. A stylus 21 fits within a receptacle in the palm PC and is used to touch the LCD and touch screen 20 to operate the device. Function buttons 19 also serve to control the functioning of the palm PC.
  • At the bottom edge of the palm PC 10 there is provided a printhead 15 flanked at either end by wheels 16 and 22. Wheel 16 is an optical encoder wheel, whereas wheel 22 is an idler wheel. These wheels may be connected so as to rotate in unison upon a common shaft. The operation of optical encoder wheel 16, idler wheel 22 and printhead 15 is described in detail our co-pending application (AP46) entitled “Portable Printer and Copier”, the content of which is specifically incorporated herein by cross-reference.
  • The printhead 15 can be capped and uncapped selectively by a capping device (not shown), which is described in our co-pending application (AP44) entitled “Capping Device for a Portable Printer”, the content of which is specifically incorporated herein by cross-reference. As an alternative to a capping device, an ink seal 36 may be provided. This might be in the form of a removable strip of elastomeric material.
  • As shown in FIG. 3, the palm PC 10 includes ink inlets 17 via which an internal ink reservoir having separate compartments can be refilled with ink. A battery charger and communications port module 18 are located, in this embodiment, on the same side of the palm PC as the ink inlets 17.
  • As shown in the exploded perspective illustration of FIG. 4, the LCD and touch screen 20 sits upon a printed circuit board 26. A number of function switches 37 are mounted on the PCB 26 and aligned with function buttons 19 so a to be depressed when the buttons 19 are used. A battery 23 which is preferably a lithium-ion rechargeable battery resides alongside the PCB and is connected electrically to the charger port module 18 and the PCB 26. A speaker 24 is also provided. The ink inlets communicate with respective compartments within reservoir 29. These compartments are best illustrated in FIG. 9. The individual ink compartments relay ink to the printhead unit 15.
  • As depicted in FIG. 5, the PCB 26 has attached thereto a dynamic random access memory (DRAM) chip 31, a print engine controller (PEC) chip 30, a QA chip 27 and a flash memory chip 28. The battery 23 connects to the PCB at connector block 38 and a ribbon cable for flexible PCB 39 connects the power and communications port module 18 to the PCB 26 via a connector block 40.
  • As shown in FIG. 9, the ink reservoir 29 is divided into a number of longitudinal compartments. In the depicted embodiment, there are separate compartments for cyan ink 32, magenta ink 33, black ink 34 and yellow ink 35. Ink from these compartments is transferred to printhead 15.
  • Power and data transfer from the PCB 26 to the printhead 15 can be by direct connection between those two units. That is, the printhead 15 may have electrical contacts soldered directly onto the PCB 26. However, in alternate configurations, an intermediate flexible PCB extending between the printhead 15 and PCB 26 can be used.
  • In use, the palm PC 10 can be operated by use of the stylus 21 upon the color LCD and touch screen 20. Function buttons 19 can also be manipulated as required. When a printed image of text and/or graphics is desired, a print command can be initiated either by use of a stylus 21 or function buttons 19. A user then draws the printhead 15 over a sheet of print media (in this case paper) as shown in FIG. 1. The ejection of ink by printhead 15 upon print media 11 is controlled by the PEC chip 30 in response to signals received from the optical encoder wheel 16 which contacts the surface of the print media 11 and rotates in use. Details of this interaction can be found in our co-pending application AP46 as cross-referenced above.
  • The internal configuration of components within the housing of the palm PC can vary depending upon requirements. For example, the printhead and ink cartridge can be an integral unit or formed separately. The printhead can extend generally normal to the extent of the ink cartridge or parallel thereto. In a further embodiment, instead of providing only two wheels 16 and 22 (one optical encoder wheel and one idler wheel) on a narrow edge of the palm PC, three, four, or more wheels might be provided say in the broad back face of base molding 14. In the case of four wheels being provided, they can be disposed in a rectangular layout in plan. One of the wheels would be an optical encoder wheel and the other wheels idler wheels. The printhead can be located generally within a space defined by a rectangle with a wheel at each corner.
  • Although the invention has been described with reference to a number of specific embodiments, it will be appreciated by those skilled in the art that the invention can be embodied in many other forms.
