20100003060 | PAPER CUTTING DEVICE AND A PRINTER WITH A PAPER CUTTING DEVICE - A paper cutting device for cutting sheet material from the lengthwise edges of the material toward the middle comprising a stationary blade and first and second movable blades with the sheet material placed between the stationary blade and the first and second movable blades. The paper cutting device enables the spacing between the stationary blade and the first and second movable blades to be opened by moving the stationary blade frame and the movable blade frame relative to each other. The first movable blade and second movable blade are supported on a first stud and second stud, respectively, near the distal ends of the edge of the blade part of the stationary blade so that the paths of the blade tips overlap when cutting the sheet material. The movable blade drive mechanism drives the first movable blade and second movable blade with the first movable blade leading and the second movable blade following. | 01-07-2010 |

20110181661 | CARRIAGE GUIDE MECHANISM AND A PRINTER - A carriage guide mechanism for a printer enables using plural rolling bearings to move a carriage along a guide shaft with no play or vibration. The carriage bearing units of the printer carriage guide mechanism have three rolling bearings each that hold the guide shaft from three directions. The outer ring of each rolling bearing makes line contact with the outer ring roller surfaces, which each face a different direction and are formed on the guide plate of the guide shaft, and contact therebetween is maintained by the urging force of a flat spring. Because chatter and vibration, particularly play and vibration around the center axis of the guide shaft, can be prevented when the carriage moves, a drop in print quality due to vibration of the printhead caused by carriage chatter or vibration can be reliably prevented. | 07-28-2011 |
