Printer with rotary cutter including tape guide on rotary blade

摘要

A rotary cutter apparatus comprises a rotary body and a holding body. The rotary body is supported by a housing so as to rotate along a rotating direction. The holding body is supported by the housing. The rotary body has a rotary blade including a first edge portion. The holding body has a fixed blade including a second edge portion. The first edge portion is configured to be in contact with the second edge portion and to be rubbed with the second edge portion. The first edge portion and the second edge portion are configured to perform cutting of an object to be cut. The object is located in an introduction path. The rotary cutter apparatus further comprises a guide member configured to be in contact with the object and to guide it when the object is fed to an inside of a rotation trajectory of the rotary body.

主权项

1. A rotary cutter apparatus comprising:
a housing; a rotary body supported by said housing so as to rotate along a predetermined rotating direction around a rotation axis; and a holding body supported to swing relative to said housing, said rotary body having a rotary blade including a first edge portion; said holding body having a fixed blade including a second edge portion; said first edge portion being configured to be in contact with said second edge portion in said rotating direction and to be rubbed with the second edge portion; said first edge portion and said second edge portion being configured to perform cutting of an object to be cut by said rubbing, the object being located in an introduction path passing in a vicinity of an end portion of said second edge portion; and said rotary cutter apparatus further comprising a guide member configured to be in contact with said object to be cut and to guide the object when the object is fed from a cutting position to an inside of a rotation trajectory of said rotary body in said introduction path; wherein said rotary blade is a first flat blade including said first edge portion having a linear shape, said fixed blade is a second flat blade including said second edge portion having a linear shape, said second flat blade includes a substantially plate-shaped second base portion, said rotary body has a rotation-side supporting portion provided on said housing so as to rotate around said rotation axis and configured to support said first flat blade so that said first edge portion is parallel with said rotation axis, and said holding body has a fixed-side holding portion configured to hold said second flat blade so that a surface of said second base portion of said second flat blade is parallel with said rotation axis, and when seen from a direction orthogonal to the surface of said second base portion of said second flat blade, said rotation axis and a straight line including said second edge portion are arranged by forming a predetermined angle, said guide member is a rotary shaft arranged in said rotary body and located at said rotation axis, and said rotary shaft has an outer diameter dimension so that a position of a lowest part of the rotatory shaft in a height direction orthogonal to a feeding surface of said object to be cut is substantially the same as a position of said second edge portion in said height direction.
