Abstract
Official abstract text for this publication.
There is provided a cutting mechanism including: a cutter blade that is capable of cutting a medium; a cutter unit to which the cutter blade is attached; and a rack gear that supports the cutter unit, in which the cutter blade is configured to cut the medium by the cutter unit moving in a traveling direction along the guide rail, the cutter unit has a second pinion gear and a fourth roller which are in contact with the guide rail to be held to the guide rail, and the second pinion gear and the fourth roller are disposed so as to interpose the cutter blade therebetween in the traveling direction.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cutting mechanism comprising: a cutter blade that is capable of cutting a medium; a cutter unit to which the cutter blade is attached; and a guide rail that supports the cutter unit, wherein the cutter blade is configured to cut the medium by the cutter unit moving in a traveling direction along the guide rail, wherein the cutter unit has a first holding portion and a second holding portion, which are in contact with the guide rail, to be held to the guide rail, and wherein the first holding portion and the second holding portion are disposed so as to interpose the cutter blade therebetween in the traveling direction. 2 . The cutting mechanism according to claim 1 , wherein the first holding portion and the second holding portion are disposed so as to interpose the guide rail therebetween. 3 . The cutting mechanism according to claim 1 , wherein the first holding portion is disposed behind the cutter blade in the traveling direction, and wherein a distance between the first holding portion and the cutter blade in the traveling direction is configured to be longer than a distance between the second holding portion and the cutter blade in the traveling direction. 4 . The cutting mechanism according to claim 1 , wherein the guide rail is configured with a rack gear, wherein the cutter unit has a driving gear disposed so as to mesh with the rack gear, wherein the driving gear meshes with the rack gear to rotate when the cutter unit moves in the traveling direction, and wherein the cutter blade is configured to rotate as the driving gear rotates when the cutter unit moves in the traveling direction. 5 . The cutting mechanism according to claim 4 , wherein the first holding portion is configured with a pinion gear that is capable of meshing with the rack gear.
