Perforation forming mechanism for use in an imaging apparatus
View Patent ↗An apparatus includes a mid-frame for supporting a back side of a sheet of media. A carrier system is configured to transport a carriage in a reciprocating manner with respect to the mid-frame. The carriage includes a bay. A perforation cartridge is configured to be received in the bay. The perforation cartridge contains a perforation forming mechanism. A controller is coupled to the perforation forming mechanism, the controller being configured to select at least one of a vertical perforation resolution and a horizontal perforation resolution of the apparatus.
1. An apparatus, comprising:
a mid-frame for supporting a back side of a sheet of media;
a carrier system configured to transport a carriage in a reciprocating manner with respect to said mid-frame, said carriage including a bay;
a perforation cartridge configured to be received in said bay, said perforation cartridge containing a perforation forming mechanism; and
a controller coupled to said perforation forming mechanism, said controller being configured to select at least one of a vertical perforation resolution and a horizontal perforation resolution of said apparatus.
2. The apparatus of claim 1 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a media type.
3. The apparatus of claim 1 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a media thickness.
4. The apparatus of claim 1 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a user selection.
5. The apparatus of claim 1 , wherein said perforation forming mechanism comprises:
a motor having a rotatable shaft;
a flywheel coupled to said rotatable shaft; and
a linkage pivotably connected between said flywheel and said perforation device.
6. The apparatus of claim 5 , further comprising:
a control circuit connected to said motor for controlling an operation of said motor; and
a sensor connected to said control circuit, said sensor being used to detect a position of said perforation device.
7. The apparatus of claim 1 , wherein said perforation forming mechanism comprises:
a motor having a rotatable shaft;
a cam coupled to said rotatable shaft; and
a cam follower connected to said perforation device, and positioned adjacent said cam.
8. The apparatus of claim 1 , wherein said perforation forming mechanism comprises:
a solenoid; and
an armature received in said solenoid and connected to said perforation device.
9. The apparatus of claim 1 , said perforation forming mechanism including a perforation device, further comprising a perforator maintenance station including an abrasive member for sharpening said perforation device.
10. The apparatus of claim 1 , further comprising:
a conveyor belt arranged for carrying paper waste generated during perforation of a sheet of print media; and
a conveyor drive unit coupled to said conveyor belt for advancing said conveyor belt.
11. An apparatus, comprising:
a mid-frame for supporting a back side of a sheet of media;
a carrier system configured to transport a carriage in a reciprocating manner with respect to said mid-frame, said carriage including a bay;
a perforation cartridge configured to be received in said bay, said perforation cartridge containing a perforation forming mechanism, said perforation forming mechanism including a perforation device; and
a perforator maintenance station including an abrasive member for sharpening said perforation device.
12. The apparatus of claim 11 , further comprising a controller coupled to said perforation forming mechanism, said controller being configured to select at least one of a vertical perforation resolution and a horizontal perforation resolution of said apparatus.
13. The apparatus of claim 12 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a media type.
14. The apparatus of claim 12 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a media thickness.
15. The apparatus of claim 12 , wherein said controller selects said at least one of said vertical perforation resolution and said horizontal perforation resolution based on a user selection.
