Abstract

A printing device includes a transport roller performing a first transport that transports recording paper drawn from roll paper in a transport direction and a second transport that transports the recording paper in a direction opposite to the transport direction, a cutter having a first blade configured to move between an advanced position and a retracted position, and a second blade for cutting the recording paper together with the first blade moving from the retracted position to the advanced position, and a guide member provided downstream of the first blade in the transport direction and guiding the recording paper during the second transport.

First claim

What is claimed is:

1. A printing device comprising:
a transport roller performing a first transport that transports recording paper drawn from roll paper in a transport direction and a second transport that transports the recording paper in a direction opposite to the transport direction;
a cutter having a first blade configured to move between an advanced position and a retracted position, and a second blade configured to cut the recording paper together with the first blade moving from the retracted position to the advanced position;
a guide member provided downstream of the first blade in the transport direction and configured to contact the recording paper when cutting the recording paper by the cutter; and
wherein at least a part of the first blade is covered by the guide member.

2. The printing device according to claim 1 , wherein the guide member has a slope that is inclined along a direction away from the second blade as going from an upstream region to a downstream region in the transport direction.

3. The printing device according to claim 1 , further comprising:
a second guide member provided upstream of the first blade in the transport direction and guiding the recording paper that moves in a direction opposite to the transport direction during the second transport.

4. The printing device according to claim 1 , wherein the guide member comes into contact with a cut edge of the recording paper cut by the cutter.

5. The printing device according to claim 1 , wherein the first blade includes a first site at least a part of which is covered by the guide member and which cuts the recording paper together with the second blade, and a second site that forms an uncut portion without cutting the recording paper.
