DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the accompanying drawings there are schematically depicted a number of different capping configurations for a portable printer. The portable printer is intended to eject droplets of ink onto a sheet of print media as the printer is held by hand and moved across the sheet of print media.
In Figures 1 and 2 of the accompanying drawings there is schematically depicted in cross-section, a printer housing 10 having located therein a fixed printhead 11. The printhead I l has a print chip 12 extending throughout its full width, that is, the width of an image to be printed. A
first embodiment of a capper arm 13, which may be metallic or formed of other material such as plastics, is pivotally mounted at 14 to the printer housing 10. The capper arm 13 resides at the exterior of the housing 10 and includes a leg 28 to which there is affixed an elastomeric pad 16 which seals against the chip 12 in the capped configuration depicted in Figure 1. The elastomeric pad 16 is moved away from the print chip 12 by leg 28 to enable printing in the configuration depicted in Figure 2.
The capper arm 13 includes an activating region 15 to which finger force can be applied as indicated by arrow F shown in Figure 2. The application of such finger force causes pivoting of the capper arm 13 about pivot 14. A spring (not shown) can return the capper arm to the position shown in Figure 1.
A second embodiment of the capping device is depicted in Figures 3 and 4. In this embodiment, the capper arm 13 is formed of a resilient. elastically deformable material such as metal or plastics. In a particular preferred embodiment, the capper arm 13 is formed of stainless steel. The capper arm 13 is fixed at 17 to the printer housing 10 at one end thereof. A fulcrum 14 (depicted schematically) resides alongside the transition of the capper arm 13 to the leg 29.
Upon the application of finger force F as indicated in Figure 4, the capper arm 13 deforms, resulting in the leg 29 moving to the position depicted in Figure 4 so as to draw the elastomeric pad 16 away from the print chip 12 for printing purposes. Upon release of the finger force F, the resilience of the capper returns it to the configuration depicted in Figure 3 wherein the elastomeric pad 16 seals against the print chip 12.
Figure 8 is a schematic cross-sectional end elevational view of a portion of a printer having a fourth type of capping device, in a capped position;
Figure 9 is a schematic cross-sectional end elevational view of a portion of the printer of Figure 8 with the fourth capping device shown in an uncapped configuration;

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the accompanying drawings there are schematically depicted a number of different capping configurations for a portable printer. The portable printer is intended to eject droplets of ink onto a sheet of print media as the printer is held by hand and moved across the sheet of print media.
In Figures 1 and 2 of the accompanying drawings there is schematically depicted in cross-section, a printer housing 10 having located therein a fixed printhead 11. The printhead I l has a print chip 12 extending throughout its full width, that is, the width of an image to be printed. A
first embodiment of a capper arm 13, which may be metallic or formed of other material such as plastics, is pivotally mounted at 14 to the printer housing 10. The capper arm 13 resides at the exterior of the housing 10 and includes a leg 28 to which there is affixed an elastomeric pad 16 which seals against the chip 12 in the capped configuration depicted in Figure 1. The elastomeric pad 16 is moved away from the print chip 12 by leg 28 to enable printing in the configuration depicted in Figure 2.
The capper arm 13 includes an activating region 15 to which finger force can be applied as indicated by arrow F shown in Figure 2. The application of such finger force causes pivoting of the capper arm 13 about pivot 14. A spring (not shown) can return the capper arm to the position shown in Figure 1.
A second embodiment of the capping device is depicted in Figures 3 and 4. In this embodiment, the capper arm 13 is formed of a resilient. elastically deformable material such as metal or plastics. In a particular preferred embodiment, the capper arm 13 is formed of stainless steel. The capper arm 13 is fixed at 17 to the printer housing 10 at one end thereof. A fulcrum 14 (depicted schematically) resides alongside the transition of the capper arm 13 to the leg 29.
Upon the application of finger force F as indicated in Figure 4, the capper arm 13 deforms, resulting in the leg 29 moving to the position depicted in Figure 4 so as to draw the elastomeric pad 16 away from the print chip 12 for printing purposes. Upon release of the finger force F, the resilience of the capper returns it to the configuration depicted in Figure 3 wherein the elastomeric pad 16 seals against the print chip 12.
In the first and second embodiments of the capping device shown in Figures 1 to 4, a user grasps the printer housing 10 and in doing so, inherently applies a force F to the activation region 15 of the capper arm 13. There may be provided a switch within the printer housing and associated with the capper arm 13 such that application of finger force F depresses the switch to set the printhead 11 into a printing operational mode.
In Figures 5 to 7 of the accompanying drawings there is schematically depicted a third embodiment of a capping device incorporating a friction clutch. In this embodiment, the printer housing 10 has mounted thereto one or more wheels 18, at least one of which can be associated with an optical sensor. One of the wheels, ie. wheel 18 in this example, can have associated with it a friction clutch 19. Wheel 18 and clutch 19 can be mounted upon a common shaft 30 (Figure 7) and biased against each other such that rotation of wheel 18 causes rotation of clutch 19 until something stops the clutch 19 from spinning, whereupon wheel 18 continues to rotate with a dynamic frictional engagement between it and the non-rotating clutch 19. In the embodiment depicted, the friction clutch 19 has a peg 20 extending laterally from it. This peg 20 is received behind a deviated portion 21 of the capper arm 13. In this embodiment, the capper arm 13 is attached within the printer housing 10 such that portion 29 moves in a linear fashion, ie. it is guided to move in a straight line.
Upon rotation of friction clutch 19. the peg 20 bears against the deviated portion 21 of capper arm 13 to move it in the direction indicated by arrow C (Figure 6). This, in turn, draws the elastomeric pad 16 away from the chip 12. It should be appreciated in this regard that wheel 18 is riding upon the print media 22 to effect wheel rotation in the direction indicated by arrow W in Figure 6. When the printer housing 10 is lifted away from the print media 22, rotation W ceases, whereupon resilience of the capper arm 13 pushes the peg 20 back to the position depicted at Figure 5 and at the same time returns the elastomeric pad 16 to seal the print chip 12 as shown in Figure 5.
In a fourth embodiment of the capping device shown in Figures 8 and 9. there is provided an internally driven camshaft 24 including an eccentric cam 23. Camshaft 24 might be selectively rotated by means of an electric motor for example. In this embodiment, the capper arm 13 is mounted to a pivot 14 and is biased by an integral spring 25 against the eccentric cam 23. That is, the integral spring 25 biases the leg portion 28 of the capper arm 13 to the position depicted in Figure 8 whereat the elastomeric pad 16 seals over chip 12. When the camshaft 24 is rotated such that the eccentric cam rotates into the position depicted in Figure 9, the capper arm 13 deforms integral spring 25 while the elastomeric pad 16 moves away from the print chip 12.
In Figures 10 and 11 of the accompanying draxvings, there is depicted a fifth embodiment of the capping device wherein the capper arm 13 is activated by an internal solenoid 26. In this embodiment, the capper arm 13 slides linearly between the positions depicted in Figures 10 and 11. The capper arm 13 includes an integral spring 25 that bears against solenoid 26. As an alternative, the spring 25 could bear against some other fixed internal structure of the printer housing 10. Attached to the capper arm 13 is a metallic plate 27 to be attracted to the solenoid 26 by magnetic interaction therewith. Application of electric current to the solenoid 26 creates a magnetic field drawing the metal plate 27 thereto. This in turn draws the capper 13 to the uncapped position where the elastomeric pad 16 has moved away from the print chip 12 to enable printing to commence.
When the solenoid is no longer receiving electric current, its magnetic field diminishes or ceases enabling the spring 28 to return the capper arm 13 to the capped position depicted in Figure 10.
It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, the elastomeric pad need not be affixed to the capper arm itself. Instead, it might be attached to the printhead 11 so as to surround the print chip 12 and come into sealing contact with a smooth surface of leg 28 of capper arm 13.
In Figures 5 to 7 of the accompanying drawings there is schematically depicted a third embodiment of a capping device incorporating a friction clutch. In this embodiment, the printer housing 10 has mounted thereto one or more wheels 18, at least one of which can be associated with an optical sensor. One of the wheels, ie. wheel 18 in this example, can have associated with it a friction clutch 19. Wheel 18 and clutch 19 can be mounted upon a common shaft 30 (Figure 7) and biased against each other such that rotation of wheel 18 causes rotation of clutch 19 until something stops the clutch 19 from spinning, whereupon wheel 18 continues to rotate with a dynamic frictional engagement between it and the non-rotating clutch 19. In the embodiment depicted, the friction clutch 19 has a peg 20 extending laterally from it. This peg 20 is received behind a deviated portion 21 of the capper arm 13. In this embodiment, the capper arm 13 is attached within the printer housing 10 such that portion 29 moves in a linear fashion, ie. it is guided to move in a straight line.
Upon rotation of friction clutch 19. the peg 20 bears against the deviated portion 21 of capper arm 13 to move it in the direction indicated by arrow C (Figure 6). This, in turn, draws the elastomeric pad 16 away from the chip 12. It should be appreciated in this regard that wheel 18 is riding upon the print media 22 to effect wheel rotation in the direction indicated by arrow W in Figure 6. When the printer housing 10 is lifted away from the print media 22, rotation W ceases, whereupon resilience of the capper arm 13 pushes the peg 20 back to the position depicted at Figure 5 and at the same time returns the elastomeric pad 16 to seal the print chip 12 as shown in Figure 5.
In a fourth embodiment of the capping device shown in Figures 8 and 9. there is provided an internally driven camshaft 24 including an eccentric cam 23. Camshaft 24 might be selectively rotated by means of an electric motor for example. In this embodiment, the capper arm 13 is mounted to a pivot 14 and is biased by an integral spring 25 against the eccentric cam 23. That is, the integral spring 25 biases the leg portion 28 of the capper arm 13 to the position depicted in Figure 8 whereat the elastomeric pad 16 seals over chip 12. When the camshaft 24 is rotated such that the eccentric cam rotates into the position depicted in Figure 9, the capper arm 13 deforms integral spring 25 while the elastomeric pad 16 moves away from the print chip 12.
In Figures 10 and 11 of the accompanying draxvings, there is depicted a fifth embodiment of the capping device wherein the capper arm 13 is activated by an internal solenoid 26. In this embodiment, the capper arm 13 slides linearly between the positions depicted in Figures 10 and 11. The capper arm 13 includes an integral spring 25 that bears against solenoid 26. As an alternative, the spring 25 could bear against some other fixed internal structure of the printer housing 10. Attached to the capper arm 13 is a metallic plate 27 to be attracted to the solenoid 26 by magnetic interaction therewith. Application of electric current to the solenoid 26 creates a magnetic field drawing the metal plate 27 thereto. This in turn draws the capper 13 to the uncapped position where the elastomeric pad 16 has moved away from the print chip 12 to enable printing to commence.
When the solenoid is no longer receiving electric current, its magnetic field diminishes or ceases enabling the spring 28 to return the capper arm 13 to the capped position depicted in Figure 10.
It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, the elastomeric pad need not be affixed to the capper arm itself. Instead, it might be attached to the printhead 11 so as to surround the print chip 12 and come into sealing contact with a smooth surface of leg 28 of capper arm 13.
