2. Description of the Related Art In recent years, printers have been developed that can print on roll paper, which is printed on roll paper and then cut into appropriate lengths to produce printed material. In this printer, in order to separate the portion printed on the roll paper from the roll paper, a cutting step of cutting the printed material slightly longer than the original length,
There may be a cutting step of cutting a printed material cut slightly larger (in this specification, paper separated from roll paper is referred to as a printed material) at an accurate position so that the printed material has its original length. is there. In the latter cutting step, an elongated cut piece is generated, and it is necessary to appropriately process the cut piece so as not to be caught in the driving member of the printer.

As one of the methods, a method of naturally dropping a cut piece downward from a space between a track of a rotary cutter and a discharge roller and receiving the cut piece into a cut piece receiving member is considered.

Further, since the roll paper has a considerable curl, the leading end of the paper rolls downward before the paper discharge roller, and the paper end may be caught between the driving paper discharge roller and the driven paper discharge roller. There are things you can't do. In order to prevent this, a guide plate is provided so as to close the path between the rotary cutter and the discharge roller, and the paper discharge end is advanced along the guide plate, so that the driving discharge roller and the driven discharge roller It is conceivable to adopt a structure that guides the end of the sheet between them. However, as described above, when trying to drop the cut piece from between the track of the rotary cutter and the paper discharge roller, the guide plate is in the way and the cut piece cannot be dropped. Therefore, one problem has been how to achieve both a structure for dropping cut pieces and a structure for providing a guide plate between the track of the rotary cutter and the discharge roller.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to allow a cut piece to be reliably dropped into a cut piece receiving member, to surely prevent the cut piece from being caught in a driving member, and to cause a paper end to advance to a discharge roller.
