Definitions
- This invention relates to a print engine.
- the invention has particular application in a print engine for use in an instantaneous print, digital camera. More particularly, the invention relates to a separating device for the print engine.
- the print engine of the present invention utilizes a page width printhead for printing an image on print media passing the printhead.
- page width is meant that the printhead prints one line at a time on the print media without traversing the print media, or rastering, as the print media moves past the printhead.
- the print media is supplied to the printhead from a roll of the print media. Accordingly, once an image has been printed on the print media it is necessary to separate that piece, containing the image, from the remainder of the roll.
- the camera with which the print engine is used may have a warning contained thereon warning a user not to pull the print media before the piece, containing the image, has been separated, a problem could arise if this warning were ignored.
- a separating device for a print engine, the separating device separating a piece of print media from a supply of print media after printing of an image by a printhead of the print engine on said piece of print media, the separating device including a separating means which acts on the print media to part said piece from the remainder of the supply of print media; a carrier on which the separating means is carried; a displacement means which acts on the carrier to displace the carrier; and an arm of resiliently flexible material which mounts the separating means to the carrier, the arm being configured to facilitate resilient bending out of the path of the print media of the separating means if the print media is forced prior to completion of a separating operation to inhibit damage being caused to the separating means.
- the separating means may be a cutter wheel rotatably mounted proximate a first end of the arm, the cutter wheel abutting against a bearing surface of a housing of a printhead assembly of a print engine to cut the print media in use to separate said piece from the supply of print media.
- the printhead may be a page width printhead and the cutter wheel may be displaceable in a direction parallel to a longitudinal axis of the printhead.
- the carrier may be a mounting block to which an opposed end of the arm is attached.
- the mounting block may be of machined metal, or a synthetic plastics material and said opposed end of the arm may be attached to the mounting block by heat stakes which are melted to retain the opposed end of the arm in position.
- the mounting block may be mounted on the displacement means to traverse a width of the print media.
- the displacement means may comprise a worm gear on which the mounting block is mounted, the worm gear being mounted in a chassis of the print engine, said chassis inhibiting rotation of the mounting block relative to the worm gear.
- the arm maybe of spring steel.

- An ink feed arrangement 702 is supported by the insert 599 beneath the cap portion 574.
- the ink feed arrangement 702 comprises a spine portion 704 and a casing 706 mounted on the spine portion 704.
- An air supply channel 711 ( Figure 8) is defined in the spine portion 704, alongside the printhead 516.
- the molding 596 includes an angled wing portion 714.
- a flexible printed circuit board (PCB) 716 is supported on and secured to the wing portion 714.
- the flex PCB 716 makes electrical contact with the TAB film 712 by being urged into engagement with the TAB film 712 via a rib 718 of the insert 599.
- the flex PCB 716 supports busbars 720 thereon. The busbars 720 provide power to the printhead 516 and to the other powered components of the print engine 500.
- a camera print engine control chip 721 is supported on the flex PCB 716 together with a QA chip (not shown) which authenticates that the cartridge 504 is compatible and compliant with the print engine 500.
- the PCB 716 includes contacts 723 which engage contacts 725 in the print cartridge 504.
- the printhead itself includes a nozzle guard 722 arranged on a silicon wafer 724.
- the ink is supplied to a nozzle array (not shown) of the printhead 516 via an ink supply member 726.
- the ink supply member 726 communicates with outlets of the passages 710 of the ink feed arrangement 702 for feeding ink to the array of nozzles of the printhead 516, on demand.
- the cutter assembly 544 includes the cutter wheel 566 which bears against the cap portion 574 of the printhead sub- assembly 508.
- the arm 568 by which the cutter wheel 566 is mounted to the mounting block is of spring steel.
- the cutter assembly 544 is displaced to traverse the print media to cut that piece of the print media, containing the image, from the remainder of the print media 542. If a user of the camera in which the print engine 500 is installed should attempt to pull that piece of the print media containing the image from the remainder of the print media prior to complete separation, damage could be caused to the components of the camera and, more particularly, the cutter assembly 554. In other words, should an undue force be exerted in the direction of arrow 728 ( Figure 10) this could cause damage to the cutter assembly 554 and neighboring components.
- the cutter wheel 566 can bend in the direction of the arrow 728, out of the path of the print media. The camera will then reset itself in readiness for the next print operation. If necessary, the image printed on that piece of the print media, which was prematurely pulled by the user, could be reprinted. The displacement of the cutter wheel 566 is monitored by the chip 721.
- the size of the print engine assembly 502 is such that most of the components of the assembly 502 are received within a footprint of an end of the print cartridge 504.
