Abstract

A processing device includes a support table to support a sheet medium, a sheet cutter to cut the medium supported on the support table, a cutter holder to move the sheet cutter in a toward-away direction in which the sheet cutter moves toward and away from the support table, and a cutter transporter to move the cutter holder in a cutting direction that is orthogonal to a transport direction of the medium. The cutter holder includes a holder movable in the toward-away direction and that holds the sheet cutter, an actuator including a rod that extends or retracts, a link connected to the rod and the holder, and a rotation shaft that rotatably supports the link so that the holder moves in the toward-away direction in response to extension or retraction of the rod.

Claims22

Dependent claims

A processing device comprising:

a support table to support a sheet medium;
a medium transporter to transport the medium supported on the support table in a predetermined transport direction;
a processing head to process the medium supported on the support table;
a sheet cutter that includes a blade portion at a tip to cut the medium;
a cutter holder to hold and move the sheet cutter in a predetermined toward-away direction so as to move the blade portion of the sheet cutter into contact with or away from the medium supported on the support table;
and
a cutter transporter to move the cutter holder in a cutting direction that is orthogonal to the transport direction;
wherein
the cutter holder includes:
a holder that is movable in the toward-away direction and that holds the sheet cutter;
an actuator including a rod that extends or retracts;
a link including a first connecting portion connected to the rod and a second connecting portion connected to the holder;
and
a rotation shaft that rotatably supports the link so that the holder moves in the toward-away direction in response to extension or retraction of the rod.
