Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device, and more particularly, to a conveying device for preventing the leading end of a sheet from entering an opening portion of a sheet conveying path when the sheet is conveyed by a printer, thereby preventing the sheet from jamming.

[0002]

2. Description of the Related Art Conventionally, in a device provided with a cutter for transporting papers and cutting the papers to an arbitrary length, a cutter comprising a circular movable blade and a fixed blade is disclosed in, for example, Japanese Patent Application Laid-Open No. 06-134692. Japanese Unexamined Patent Publication No. 09-07619
No. 0 publication. However, in these prior arts, the trajectory where the movable blade, which is also the opening of the paper transport path, moves is in an open state, and when the leading edge of the paper passes through it, the leading edge of the paper is There is a problem that paper may jam and cause paper jam.

[0003]

The first problem with the conventional paper transport described above is that when the leading edge of the paper passes through the opening of the paper transport path during the transport of the paper, the opening of the paper transport path may be reduced. The leading edge of the paper may enter the paper, causing paper jam.

[0004] The reason is that, when the leading end of the sheet passes through the opening of the sheet transport path, there is no mechanism provided for guiding the sheet to the sheet guide at the opening of the sheet transport path.

[0005]

According to a first aspect of the present invention, there is provided a transporting apparatus for transporting papers and cutting the papers to an arbitrary length. A circular blade base movable along the fixed blade, and a cutter comprising a disk-shaped movable blade which is in a disk shape and whose flat surface is in vertical contact with the fixed blade and is supported by the round blade base, and a moving locus of the movable blade When the leading edge of the paper passes through the opening of the paper transport path above the paper, it is rotated around the axis to the opening of the paper transport path, and interferes with the movement locus of the round blade base in a rotatable state. A cutter shutter, which is arranged so as not to rotate and is rotated by the power of a motor or manually, is provided so that the leading end of the sheet is guided by the cutter shutter during sheet transport without affecting the movement of the round blade base. Between the paper and the paper in the transport direction. It is configured to prevent clogging.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the transport device of the present invention.

FIG. 2 is a top view showing one embodiment of the transfer device of the present invention.

Hereinafter, a printer equipped with a thermal head will be described with reference to the drawings as an example of a transport device according to the present invention.

The transporting apparatus of the present invention is provided with a cutter 5 for transporting sheets and cutting the sheets to an arbitrary length. The cutter 5 has a plate shape having a length equal to or greater than the sheet width. A fixed blade 2, and a circular blade (moving blade) 3 that moves along the fixed blade 2 while being rotated by the movement of the round blade base 4, the plane portion of which comes into contact with the fixed blade 2 in a disk shape. In the conveying apparatus provided with the cutter 5, a movable cutter shutter 6 is provided in the opening 11 of the sheet conveying path of the sheet 1 on the movement trajectory of the movable blade 3.

In FIGS. 1 and 2, a plate-shaped fixed blade 2 having a length equal to or larger than the width of the paper 1, a round blade base 4 movable along the fixed blade 2, and a disk-shaped flat portion are provided. A cutter 5 comprising a movable blade 3 which comes into vertical contact with the fixed blade 2 and is supported by the round blade base 4 is provided.

Here, a paper guide 8 for guiding the paper 1 downstream of the movable blade 3 and the round blade base 4, that is, in the transport direction 1 a of the paper 1, and a paper guide 9 facing the paper guide 8 are provided. .

On the other hand, the thermal head 12 is located on the upstream side of the round blade base 4, that is, on the side opposite to the transport direction 1a of the transported paper 1.
And a platen 13 disposed close to the fixed blade 2. The thermal head 12 is urged toward the platen 13 by a spring (not shown). Thermal head 1
A paper guide 10 for guiding the paper 1 is mounted between the round blade base 4 and the round blade base 4 so as not to interfere with the movement locus of the round blade base 4.

Further, the cutter shutter 6 is arranged so as not to interfere with the movement locus of the round blade base 4 in a state where the cutter shutter 6 can rotate about the shaft 7 to the cutter shutter position 6a.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIGS.

The paper 1 is composed of a thermal head 12 and a platen 1
3, the platen 13 is rotated by a motor (not shown) and applied to the thermal head 12, so that the printing operation on the paper 1 is performed. The printed sheet 1 is guided by a sheet guide 10 and a fixed blade 2, the leading end of the sheet is guided by a movable cutter shutter 6, smoothly passes between a sheet guide 8 and a sheet guide 9, and is conveyed in a conveying direction 1 a. You.

When the paper 1 is transported to a predetermined length and the cutting position of the paper 1 comes to a position where the fixed blade 2 and the movable blade 3 come into contact with each other, the paper 1 is stopped.

Thereafter, when the round blade base 4 is moved in the cutting direction 4a along the fixed blade 2 by driving a motor (not shown) inside the cutter 5, the moving blade 3 moves while rotating and the fixed blade 2 moves. Then, the sheet 1 is cut. After cutting, the round blade base 4 is returned to its original position. At this time, the locus of movement of the round blade base 4 exists as the opening 11 of the paper transport path.

Therefore, when the printing operation is performed on the paper 1 or when the paper 1 is transported, the leading end of the paper 1 is positioned at the opening 11 of the paper transport path.
When the paper 1 passes, the cutter shutter 6 is rotated to the cutter shutter position 6a, and the sheet 1 is conveyed while being guided.

As described above, the transfer device of the present invention
A plate-shaped fixed blade 2 having a length equal to or greater than the width of the sheet 1; a round blade base 4 movable along the fixed blade 2; In a transport device including a cutter 5 including a movable blade 3 supported by a blade base 4,
The movable cutter shutter 6 is provided at the opening 11 of the paper transport path on the paper transport path along the movement locus of the round blade base 4 so that the leading edge of the paper can be transported without affecting the movement of the round blade base 4. Is guided by the cutter shutter 6, smoothly passes between the paper guide 8 and the paper guide 9, and is transported in the transport direction 1a, so that a jam (paper jam) at the time of transporting the paper can be prevented.

[0021]

As described above, the first effect of the transport apparatus of the present invention is that jamming (paper jam) during transport of paper can be prevented before transporting paper.

The reason is that by providing a movable cutter shutter at the opening on the paper transport path on the movement locus of the round blade base, the leading edge of the paper is guided by the cutter shutter during paper transport, and the paper guide and the paper guide This is because the paper passes smoothly between the guides and is transported in the transport direction.
